SPECIFICATION forming part of Letters Patent No. 518,750, dated April 24, 1894.

Application filed-July 12, 1893. Serial No. 480,268. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. BLUE, of Wheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful Improvements in Work-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, ref{ erence being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in work holders, and it consistsin the novel combination and arrangement of parts which will be fully described hereinafter and particularly pointed out in the claims.

My invention is especially directed to the provision of a work holder which is compact in-its arrangement, convenient and accessible however approached by the operator and which is capable of every adjustment which will aid the operator in executing the work in hand.

Referring to the accompanying drawings: Figure 1, is a side elevation of my improved work holder, showing the work table adjusted to one side and at an angle in dotted lines." Fig. 2, is a plan view of the same. Figs. 3

and 4, are vertical sectional views, taken at right angles to each other, of Fig. 2. Fig. 5, is a plan view of the upper portion of the device, the work table being removed. Fig. 6, is a view of the detachable interiorly screw threaded support. Fig. 7, is a plan view of the work table, the clamping jaws being removed. Fig. 8, is a detail view of the normally stationary clamping jaw. Y

A designates the base or stand having at its upper end the laterally projecting arm A, to which is removably secured the interiorly screw threaded standard support B, which is split longitudinally as shown at B. Lugs b, are projected from opposite sides of the said split, and the same are adapted to be drawn together, thereby contracting the vertlcal .screw threaded opening, by means of screw 1). The object of this arrangement is to bind the screw threaded standard 0 which is adj ustable in the said support, after having been turned to the proper position, so that the same will not turn or yield in any way to pressure exerted upon it through the medium of the work table, presently to be explained.

. D is a vertically slotted head having sockets D upon its lower end which fit down over the upper end of standard 0 to which it is fixedly secured'by set screw d. Journaled concentrically in the slot of the head is the segmental projection E, depending from the annular recessed support F. Projection E, together with support F, are held in avertical position or at any angle thereto, by means of set screw H extendinginward through projecting portion G of head D.

One side of support F is slit vertically as shown in Fig. 5, and projecting from opposite sides thereof are lugs f, which are adapted to be drawn together, thus contracting the recess in the support by means of screw g, projected therefrom and operated by a movable vise handle-g.

I designates the table or work holder proper,

and depending from its under side is the annular boss J having the peripheral groove J, which is engaged by screws j, projecting through support F and by this means the said boss while free to revolve in the recess of the support is held from vertical displacement.

When the table or work holder has been adjusted to the desired angle the screw g, is tightened thereby contracting the slit in head F, and binding bossJ sufficiently to prevent the same from radial movement.

The top surface of table I is provided with a transverse depression L, at the bottom of which are the vertical slots M and N, which communicate with a corresponding transverse recess Z, on the .under side of the table. Extending ,longitudinally in slot M is screw shaft 0 which reciprocates head P therein, while movable in slot N, is head P. Slots M and N are narrower than depressions L, l, and the said heads, being formed with enlarged upper and lower ends to correspond with said depressions while enabled to reciprocate freely through the slot, yet. are held positively from vertical movement. Removably secured to head I" is jaw Q, from which depends stud Q which is adapted to engage one of a series of openings q, arranged adjacent the edge of recess N, and by this means the said jaw is held at any desired distance from the center of the table. Head P carries a correspondingly formed jaw and is in line with and is adjustable to and from jaw Q as is apparent. The enlarged upper ends of head M, N are the same depth as the recess L, so that the projecting surfaces of the jaws rest and move upon the top surface of the table. The opposite sides of table I are provided with the inward cuts 1', for the purpose of afiording the operator more convenient access to portions of the work he may have in hand. Support Bis projected a short distance above lateral arm A, and formed around this projecting portion is the groove R, and adapted to turn therein is the arm S made in longitudinal sections, as shown, and upon the outer end of this arm is supported the revoluble tool box T.

By means of the construction herein shown and described it will be seen that the work table is afforded every possible adjustment with devices for holding the same in whatever position it may be turned.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An improved work holder comprising a support, an annular clamping band upon its upper end, a table, and a boss depending therefrom which extends into the said annular clamp, substantially as shown and described.

2. An improved work holder comprising a table having transverse depressions upon its upper and lower sides, a vertical slot connecting the depressions, heads movable in the slot and enlarged at their opposite ends to fit the depressions, clamping jaws carried by the heads, and a means for adjusting one or both of them substantially as shown and described.

3. An improved work holder comprising a table having a transverse slot, a head movable therein, a jaw removably secured to the head and projecting over the table, a stud depending from the jaw which engages one of a series of openings in the top surface of the table, and a second jaw adjustable in relation with the first named jaw, substantially as shown and described.

4:- An improved work holder comprising a table having depressions in its upper and lower sides, the said depressions being connected by two slots which are in line, a head movable in each slot, which heads are enlarged laterally at their respective ends to fit the recesses of the support, jaws carried by the heads, a means for. holding one of the heads rigid with the support or table, and a screw extending longitudinally through the other head for adjusting it, substantially as shown and described.

5. An improved work holder comprisinga table having inwardly extending cuts 1 upon opposite sides, and dogs adj ustable in a line substantially at right angles and adjacent to the line of said cuts, substantially as shown and described.

6. An improved work holder comprising a base, a vertically recessed support secured thereto which support is slit vertically upon one side, a means for contracting the edges of the said slit, a standard movable vertically in said support, and a work holding device carried by said standard, substantially as shown and described.

7. An improved work holder comprising a base, a vertically recessed support secured thereto, standard movable in the support and a work holding device upon the upper end of the standard, and a projection upon the upper end of the said support having an annular groove, and a tool box support clamped in said groove in which it is adapted to turn, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
