1 Claim.

The present invention rel-ates to improvements in work holders and the like and provides a device of this character whereby the holder may be built up the required height and adjusted to a precise measurement to one thousandth of an inch if necessary.

Another advantage of the invention is the provision of a cone shape attachment which is used where other attachments fail to serve the purpose.

Still another advantage of the invention is to provide a pivoting attachment designed to accommodate certain work not available in the remaining attachments.

With the foregoing in mind, it will become readily apparent that the invention possesses further advantages, all of which will be clearly revealed during the course of the following detailed description, illustrated throughout the accompanying drawing, and more fully pointed out in the sub-joined claim.

With reference to the drawing:

Figure 1 is a sectional assembly of the device taken through the center thereof and showing the major elements included.

Figure 2 is a transverse sectional view taken upon line 22 of Figure 1.

Figure 3 is a transverse sectional view taken upon line 33 of Figure 1.

Figure 4 is also a sectional view taken upon line 4-4 of Figure 1.

Figure 5 is a top plan view of the grooved attachment; and Figure 6 is an elevation thereof.

Figure '7 is an elevation of the rectangular block attachment.

Figure 8 is a plan view of one of the shim-s; and Figure 9 is an edge view thereof.

Figure 10 is a sectional assembly of the pivoting attachment.

Figure 11 is a top plan view of the graduated base member.

Figure 12 is a top plan view of one of the block members.

All of the views of the drawing are drawn to approximately full size.

The invention comprises base member I having internal threads so as to threadedly engage plug member 2 as clearly shown in Figure 1, and the circumferential face of said plug member is preferably knurled, and the circumferential face of said base or IA is graduated to one thousandth part of an inch, and the lower portion of the base is hexagonal in formation in order that the base may be held against turning a support.

A set screw 3 is provided where shown and when tightened, engages the threaded shank of the plug for the purpose of holding plug member 2 in a fixed relation with respect to base I. Indicator 4 is also provided and is attached to plug member 2 by screw 5, and it is noted that indicator 4 extends to a position in direct contact with graduated surface IA.

Plug member 2 is provided with spaced apart apertures 6 upon the top thereof so as to engage similar shape pins 1 of block 8, and said block has apertures so as to engage pins 9 of block I0. Block ID has apertures to engage pins H of block I2, and the latter block also has apertures so as to engage pins I 3 of block I4. Block I 4 has apertures so as to engage pins I5 of elongated block I6, also similar apertures I I are formed within block l6 where indicated.

Referring to Figure 1 it is clear that supporting post I8 is provided as shown, and said post being counterbored as at I9 so as to form a'su'itable seat for base I as shown. Since the base has fiat side faces and rests in a similarly shaped pocket in the post, the base will be held against turning movement when the plug 2 is turned.

In Figures 8 and 9 a typical shim 20 is indicated and having apertures 2| therein so as to correspond with any of the pins, 1, I0, I3 and I5.

In Figures 5 and 6 an attachment member adapted to accommodate rounds of every description is indicated at 2'2 and formed with transversely extending groove 23 as shown, also spaced apart depending pins 24 so that this attachment is interchangeable with the remaining elements of the device;

In Figure 13 the cone shape member 25 is shown with pins 26 therein. This member is particularly adapted for close places where the other elements of thedevice fail to be useful and is interchangeable with the remaining elements.

In Figure 7 rectangular block 2 7 is provided with pins 28 therein and is adapted for particular work suitable only for this shape of block.

In Figure 10 the pivoting unit comprises base member 29 which is provided with a socket within the upper portion thereof so as to engage ball 30 of upper member 31, also pins 32 within said upper member so that the pivoting unit is interchangeable with the remaining elements of the device.

It is understood from Figure 1 how the various elements may be built up one above another so as to accommodate any class of work, and in this figure the assembly is shown resting upon table A of the machine upon which it is used. It is further understood that the device is designed so as to hold work upon milling machines, shapers, surface grinders and the like.

Having thus fully described my invention, what I claim as new is:

A working supporting tool comprising a support having its upper face formed with a pocket, a base removably seated in said pocket, the pocket and the base having confronting flat peripheral faces engaging each other to prevent the base from turning in the pocket, said base being 10 formed with a threaded core, a plug over the base having a threaded shank screwed into the bore to adju-stably hold the plug in engagement KARL HUBSCHNEIDER.
