Among such devices are angle irons of different types such as a right angle iron, measuring irons, slotted angle irons, pallet irons, box angle irons, sine blocks, sine bars, V blocks, many of which are disclosed in catalogue number 511 of Taft-Peirce Manufacturing Co. of Woonsocket, R.I. Such devices are precision made and are employed in tool making by clamping a work piece thereto so that the work piece may be supported and precisely positioned with respect to a machining tool, grinder, or some other tool member for precise working of a surface on the work piece. Such prior proposed work holding devices were useful for specific tooling operations. In the event a different tooling operation was required the work piece was often transferred to a different type of work holder. Such transfer of a work piece to a different work holding device was time consuming because of the care and accuracy with which the work piece was required to be secured to the work holder device and precisely positioned with respect to the tool.
SUMMARY OF INVENTION The present invention relates to a novel work holding means so constructed and arranged as to readily position a work piece with respect to a tool for precise, ac-
curate working or machining of the work piece.
An object of the present invention is to disclose and provide a work holding means wherein a work piece is capable of being positioned in a multitude of different positions for a working operation while maintaining the desired rigid standards of preciseness and accuracy for such work.
Another object of the present invention is to disclose and provide a work holding device which can be utilized for positioning a work piece and performs the functions of several prior proposed tool holding devices such as sine blocks, V blocks, angle blocks, whirly-gigs, indexing, and other functions without providing socalled secondary set-ups.
Still another object of the present invention is to disclose and provide a multi-purpose work holding device having rigidity, rapid adjustment and a rugged construction whereby work pieces of various type may be readily positioned, secured and worked upon.
Generally speaking, the present invention contemplates a work holding device provided with a body member similar to a right angle iron. The body member is provided with a plurality of sets of V grooves so arranged and spaced to permit its use as a sine bar or block. The body member is also provided with selectively arranged holes adapted to receive pins for positioning a work piece for grinding at normal angles or grinding at compound angles. The body member is provided with means for registering its relationship with respect to a work table in such a manner that the work holding means is capable of positioning a work piece in a desired relation to the tool with the set-up time minimized. The right angle body member is further provided with V grooves and index recesses adapted to receive an indexing device cooperable with the body member whereby angular rotational adjustment of a cy- 2 lindrical work piece may be readily achieved with respect to a tool.

Referring first to FIGS. 1 and 2, a work holding means embodying this invention may comprise an integral body member generally indicated at 20 having generally the shape and configuration of a right angle iron. Body member 20 may comprise a first body portion 21 and a second body portion 22 disposed at right angles to body portion 21. Body portions 21 and 22 may be of the same cross-sectional thickness and of the same width. Body portions 21 and 22 provide first rectangular flat finished surface means 23 and 24 in contiguous relation and of a uniform width.
Work holder means 20 also includes a web member 25 of angular configuration and comprising a web leg 26 parallel to body portion 21 and a web leg 27 parallel to body portion 22. Web member 25 bridges the included angle of 90 degrees between the body portions- 21 and 22. Web leg 26 is provided with a surface means 28 lying in a plane common to the plane formed by the top edge face 29 of body portion 22. Web leg 27 provides a surface means 30 lying in a plane coplanar with the plane of edge'face 31 of body portion 21, said second surface means 28 and 30 being at right angles to each other and in contiguous relation. The second surface means 28 and 30 are of reduced width as compared to the width of the first surface means provided by body portions 21 and 22.
I The structure briefly defined above is essentially that of a right angle iron. The first and second surface means are finished in precise 90 degree relationship and surfaces'are in precise parallelism. Preferably second surface means 28 and 30 on web member 25 are wider than the surfaces provided on prior right angle blocks for purposes later described.
Means are provided for positioning the body member 20 for performing angular work, that is grinding, machining or cutting a surface on a work piece at an angle to an axis of the work piece. Such means include a set of V grooves 32 on surface means 23 of body portion 21, another set of V grooves 33 on surface means 24 of body portion 22,'and still another set of V grooves 34, provided on the second surface means specifically the surface 28 and the edge face 29 of the leg member 26 and body portion 22 respectively. The spacing of the grooves in each set of grooves is a sine related distance apart, such spacing being precise. Each set of V grooves 32, 33 and 34 is adapted to receive a roll or dowel 35 of the same diameter. When dowels 35 are associated with a set of V grooves, the body member 20 is readily adapted to perform the function of a sine bar or sine block from any one of three different surfaces. Such use of body member is illustrated in FIG. 2 where dowels 35 are positioned in the set of V grooves 32, one dowel 35 being positioned upon a finished reference surface 36 and the other dowel- 35 being positioned at a selected distance above reference surface 36 by one or more shim elements 37 for precisely positioning the exemplary work piece at a selected angle, for example three degrees, with respect to a plane parallel to reference surface 36. In FIG. 2 the work piece is illustrated as a core pin 39 having a head 40 and a free end 41 on which an angular surface 42 is to be formed by a suitable tool 43. Work piece 39 is securely and precisely positioned in a longitudinally extending V groove 45 provided in the second surface means 28 of the web leg 26. A suitable clamp 46 may hold work piece 39 in V groove 45.
FIG. 4 illustrates the body member 20 carrying the work piece 39 as illustrated in FIG. 2 but positioned at a much greater angle such as 30 by a shim block 48 to permit forming or cutting of tapered surface 42 of the work piece 39. In addition, while work piece 39 is held on device 20 as shown in FIG. 4, notch 49, flat 49a, and slope 49b may be cut therein without changing the set up of the work piece on device 20. Thus a plurality of complex cutting operations may be performed with accuracy, such capability being enhanced by the freedom to measure with respect to the work piece. In collet set ups, the work piece must be removed, marked and repositioned.
Dowels are normally removable from their associated transverse grooves and are not fixed therein. In the event of a specific work setup where dowels 35 are desired to remain fixed in a V groove, a suitable set screw means may be provided in each dowel for cooperation with a tapped hole in the bottom of a V groove. However, removability of dowels 35 is preferred 'because dowelsare not needed'for non-angular set ups, may be obstructive in other set ups, and provide the advantage of selective placing of dowels 35 in one of the other sets of V grooves on the body member as shown, for example in FIG. 5. v
In FIG. 5 dowels 35 are shown positioned in V grooves 33 provided on the body portion 22. One dowel 35 is in contact with reference surface 36 and the other dowel 35 is seated upon suitable shims 37 to provide a selected angle such as 5 degrees for grinding an angular end face 50 on the free end of work piece 39.
Use of the V grooves in sine relation is further shown in FIG. 10 wherein dowels 35 are positioned in the set of V grooves 34 provided in the end face 29 of body portion 22 and in the distal end of leg member 26 of the web member 25. ln FlG. 10 a different form of work piece 39a is shown clamped to surface 23 of body portion 21 to permit grinding of an angular face on work piece 39a. The body member 20 is positioned at a'selected angle by a shim block 51.
The work holding means of this invention is also readily adapted to the forming or cutting of surfaces at compound angles on a work piece. FIGS. 6, l1 and 12 show positioning of a work piece on the body member 20 to permit such forming of a compound angle. In FIG. 6 body portion 22 is provided with a plurality of arcuately arranged holes 53 and 54 which converge toward the upper section of body portion 22 and which include reference bottom holes 530, 54a parallel to surface means 23 and a preselected distance apart hereafter referred to as Sdistance. S-distance is the distance between centers of sine rolls, buttons, or the equivalent, for example 5 inches, 10 inches, and is a preselected distance to correlate with reference tables com monly used in the machine tool industry for sine plates, sine bars, and other sine equipment to permit rapid accurate positioning of work (Taft-Pierce Catalog No. 51 1, pages 6 10 inclusive). In this example S-distance is used for the distance between centers of a reference hole 53a and any one of holes 54 a, 54, or a reference hole 54a and any one of holes 53a, 53. Holes 54 are arcuately spaced apart an S-distance from bottom reference hole 53a so that insertion of dowel pins 56 in selected holes will generate angles with respect to a plane parallel to the plane of surface means 23 of from 0 to 10, 20, 30 and 45. Holes 53 are similarly related to bottom reference hole 540. Other angles can be readily achieved by using well known gauge blocks since the spacing between the pins 56 in respective holes 53a, 54 and 54a, 53 are always the preselected S-distance apart.
AS best shown in FIGS. 11 and 12, a work piece such as 39b may be clamped by suitable means, not shown,
against the surface means 24 of the leg portion 22. Body member 20 may be positioned at a selected first angle by using dowels 35 in V grooves 32 and a shim block 57. Pins 56 may be inserted in the selected pin holes 53 and 54 to provide a suitable angle upon which a mounting bar 59 is supported to position work piece 39b at the desired compound angle with respect to the tool 60. From a consideration of FIGS. 11 and 12 it will be readily apparent that the angular surface at 61 being formed by the tool 60 lies at a compound angle with respect to the normal axis of the work piece 39b.
Means for further adjustably positioning the work holder device of this invention in order to selectively position a work piece with respect to a tool includes elongated angle slots 64 and 65 provided in body portions 21 and 22 respectively. Each slot 64 and 65 extends through said body portions and is disposed at an angle of 45 to the longitudinal and lateral axis of the body portions. Each slot 64 and 65 is adapted to receive therethrough a bolt means 66 which serves to securely clamp the work holder device to a work bed or table provided with reference surface 36. Body member20 may thus be readily angularly positioned with respect to the axes of the work table. To facilitate precise alignment with respect to the axis of the machine, alignment holes 67 are provided on the longitudinal and transverse axes of the body portions and spaced apart a preselected S-distance. Alignment holes 67 receive pins which may extend into the T-slot in the machine bed and bear against one or the other edges thereof for precise reference and alignment purposes. Adjustment of body member 20 with respect to a tool 7 is thus further facilitated and the body member may be precisely mounted on the machine table in proper relationship to a tool with set-up time minimized.
In FIG. 3 body member 20 is positioned with its table face or surface means 23 against a reference surface 36 of a work table and held thereagainst by the bolt means 66. In FIG. 3 a work piece 39 is positioned with its axis parallel to reference plane 36 for the purpose of providing an axially extending slot 70 in the free end 41 of the work piece by means of a disc cutter cutting tool 7 1.
Means for indexing a work piece such as a headed ejector or core cylindrical rod 72, FIG. 7, into a selected rotational position is another advantage provided by the construction of body member 20. In FIG. 7 work piece 72 is seated in longitudinally extending V groove 45 provided in the web leg 26. Along the length of web leg 26 and adjacent to opposite ends thereof are provided recesses 73 and 74 adapted to receive an index bushing 75. Index bushing 75 includes a through bore 75 of a selected diameter to readily slidably accommodate cylindrical work piece 72. Index bushing 75 is secured against relative rotational movement with respect to work piece 72 by a set screw 77, FIG. 9. Index bushing 75 is thus in fixed relation to the work piece and is loosely accommodated in recess 73 so that the work piece 72 may firmly rest in the V groove 45. Head notches 73a, 74a are formed at a selected distance from working surfaces 24 and 27 to receive heads 40 of standard core or ejector rods.
Index bushing 75 is provided with a plurality of selectively angularly spaced radial bores 79 adapted to receive one end of an index pin 80. Bores 79 may be provided in selected angular spaced relation such as 90, 45, 30 and apart. To facilitate location of a plural- 81 (which may have a small stop flat therein) serves as a positive precise top for rotationally positioning work piece 72. Thus to determine the precise diameter upon which the slot is to be cut, FIG. 3, the index bushing will be turned to a selected position before the work piece 72 is held and clamped in the V groove 45. In the event a cross slot was desired at the index pin would be placed in an index bore spaced 90 from the initial pin position and after the pin had been placed in the index bore and positioned against edge 81, the cross slot could be cut in precisely 90 relations with the original slot.
Likewise, as shown in FIG. 8 index 75 may be selectively rotationally positioned to turn work piece 72 through successive 90 angles to provide flats 83 on the end of work piece 72. In FIG. 8, work piece 72 is illustrated as mounted in a V groove 85 extending longitudinally in surface 30 of the web portion 27. Leg portion 27 is provided with index receiving recesses 86 in a manner similar to the recesses 73 and 74 of web portion 26.
It is important to note that longitudinal V grooves 45 and 85 provided in respective surface means 28 and 30 are symmetrical with respect to the body member and in this example, the apices of the Vs lie in a vertical plane longitudinally bisecting the body member. A work piece secured in one of the longitudinal Vs 45 and 85 is thus precisely related to other reference or working surfaces to thereby permit additional work on the work piece without removing the piece from the V groove. Since the surface means 28 and 30 are wider than those in a right angle iron, the V grooves 45 and 85 may be largerand may accommodate work pieces of greater diameter. In addition, one of the working V grooves 45, 85 may be made wider than the other so that thediameters of work pieces accommodated by the V grooves 45, 85 may range up to two or three inches. The body member thus is useful as a V block.
In FIG. 8 it will be noted that the body member 20 is being utilized in another position to angularly position work piece 72 with respect to a tool 87. Index bushing 75 and the extra width of web means 25 and the selected size of the V grooves 45 and 85 therein provide for accommodation of cylindrical work pieces of varying diameter as for example from 7% inch to 2 inches or more. This arrangement also provides for hand spin grinding of a work piece by loosening the clamp means and so returning the work piece by hand.
Some of the features mentioned above which have been applied to a right angle iron may also be applied to other work holding devices as illustrated in FIGS. 13-16 inclusive. In FIGS. 13 and 14 an angle plate is provided with a base or table portion 101 and an upstanding work portion 102 at right angles to portion 101. Each of the portions 101 and 102 may be provided with a slot 103 disposed at a 45 angle to the right angle axes of the leg portion for reception of a work table hold-down bolt means as previously described. The center of slot 103 is at the intersection of the right diate set-up and alignment of the angle of the work on -a work table. Each of the portions 101 and 102 may also be provided with the arcuately arranged holes 106 and 107 in which the bottom holes are spaced apart a sine distance and the remaining holes are spaced apart a selected angular relationship with respect to the bottom hole of the other arcuate set of holes. Thus the angle plate 100 may support through the use of pins received in holes 106 and 107 a work piece for presenting the work piece to a machine tool for grinding a surface thereon at a selected angle.
In FIGS. 15 and 16a V block 110 is illustrated. V block 1 includes a set of V grooves 11 l on table surface 112 of the block and also a set of V grooves 113 on a contiguous surface. Sets of grooves 111 and 113 include V grooves of selected width and depth and the grooves ofeach set are spaced apart a preselected S- distance and are adapted to removably receive rollers or dowels 114 to position the V block at a selected angle by means of shims or guage blocks 115- as shown in FIG. 15.
A V block such as lltl is normally provided along one surface with a relatively wide and deep V groove 116 adapted to hold a cylindrical work piece such as work piece 117. In spaced relation along V groove 116, V block 110 may be provided with an index bushing recess 119 and a work piece head recess 120. A suitable strap type clamp means 121 may be provided for securely holding work piece 117 in the V groove. Index bushing 122 may be provided with angularly spaced, radially extending sets of holes 123 as in the prior embodiment of an index bushing, said holes receiving an index pin 124 for rotationally positioning work piece 117.
It will thus be apparent that V block 110 is now capable of providing the function of a sine plate in combination with a means for rotationally positioning a work piece with respect to its axis for angular and rotational working thereof.
The advantages of the right angle iron will be readily apparent to those skilled in tool making. The work holding body member 20 not only may be used for the purposes which it previously served but also is capable of use as follows: first as a reversible sine plate or block employing one of three different surfaces on the block and thereby eliminating a secondary set up in a machining or inspection operation, second, a compound sine block utilizing one of two different surfaces to readily locate and position a work piece for the working thereon of a compound angle; third, as a V block by utilizing the 45 angle hold-down slot on each of two leg portions of the angle iron together with precise alignment of the body member by the alignment holes in the leg portions of the block for fast and accurate set-ups; fourth, rotationally or angularly positioning of a cylindrical member with respect to its axis by means of the index bushing.
The modified right angle iron as described above is thus adapted to perform a sequence of complex operations with high interrelated preciseness and accuracy, without loss of time caused by the necessity previously of secondary set-ups. The work piece is capable of being positioned with respect to a tool in virtually any gular flats, tapers, squares, and chamfers may be readily machined or ground. Those skilled in the toolmaking art will recognize the versatility and usefullness of the several adaptations of the above-described work holding means which embodies this invention.
It will also be understood that costs of set-ups are minimized because of the several features of construction of the device 21), that inspection of the work is facilitated, and that measurements along the work can be readily made. The angularly disposed slot in each of the body portions enhances set up time because no indicating is required; that is the step of precisely locating a surface of a work piece upon which work is to be performed (Taft Pierce Catalog No. 511 page 2). The work holding device 20 constructed with the features in many different positions for work thereon by atool.
The several features of this invention have been exemplary shown with respect to a right angle iron, angle block, and V block. They may also be applied to a tool makers vise which has precision finished surfaces on. an elongated generally rectangular body, having ,an upstanding fixed jaw portion at one end and a slidable jaw member movable by a feed screw threadedly carried in an upstanding body portion at the other end of the body. Sets of transverse V grooves spaced'a preselected S-distance apart may be cut in the bottom and side surfaces of the vise body to receive sine rolls for positioning the vise body at a selected angle of gauge blocks. In addition the upstanding fixed jaw portion may be provided with arcuately arranged holes a preselected S-distance apart such as holes 53 & 54 described above. Thus the modified vise permits positioning a work piece for angular and compound angular working in addition to its normal use as a vise.
It is understood that various other modifications and changes may be made in the work holding means described above which come within the spirit of this invention and all such changes and modifications come within the scope of the appended claims are embraced thereby. I
