HARRY COOPER, OF SAN ANTONIO, TEXAS, ASSIGNOR OF TW'O-THIRDS TO WVILLIAM \V. OOULSON, OF SAME PLACE.

ADJUSTABLE BENCH-HOOK.

filPl-JCIFICATION forming part of Letters Patent No. 302,385, dated July 22, 1884:.

Application filed December .27, 1883. (N model.)

To all, whom it may concern.-

Be it known that I, HARRY Coornn, of San Antonio, in the county of Bexar and State of Texas, have invented a new and Improved Adjustable Bench-Hook, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is aplan view of my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional elevation of the same, taken through the line we", Fig. 2. Fig. 4 is a sectional plan view of apart of the same, taken through the line y y, Fig. 2.

The object of this invention is to facilitate the adjustment of bench-hooks and promote security in holding the work.

The invention consists in a bench-hook constructed with a plate carrying a sliding bar, to which is adjustably secured a hook. The sliding bar and hook are locked in place by a clamp and cam attached to the plate, and the plate and its attachments are locked to the bench-front by a stationary lug attachedto the plate, and a movable lug attached to alever pivoted to the said plate and locked in place by a cam, so that the said hook can be readily adjusted upward,

0 3 work to be held may require, as will be hereinafter fully described.

A represents an ordinary work-bench,which is provided with a stationary hook, B, in the 5 ordinary manner for the forward end of the is held by the hook O, the shank of which extends downward at the forward side of the bench A, and has two vertical slots, 0, formed in its lower end toreceive the,screws C by which the said hook issecured to the bar D, so that by loosening the said screws G the hook G can be raised and lowered as the work to be held may require. The bar D is made with dovetailed edges, and slides in a dovetailed groove in the upper part of the plate E, and is locked in place by a clamp, F, which is placed upon the screw G,and pin H, attached to the plate E, and which pass through holes in the middle and lower parts of the said clamp F. The fordownward, forward, and backward, as the work to rest against. The rear end of the work' ward side of the iniddlepart of the clamp F is rounded or beveled longitudinally to fit into the correspondingly-concaved inner side of the lever I, which is placed upon the screw G, and is secured in place by a nut, G, screwed upon the said screw, so that the said lever will act as a cam to lock and release the clamp F. By this construction, by turning the cam-lever I to theright or left,the clamp F willbe forced against the bar Band will lock the said bar and the hook O securely in place, and by turning the said cam I into a vertical position the bar D and hook G will be released, and can be readily adjusted as the work to be held may require. The plate E is provided with two inwardly-projecting pins or lugs,-J K, to pass through holes L in the front of the bench A, and support the said plate E and its attach ments. The pin or lug J is stationary, and is attached to the plate E. The pin or lug K is .70 movable, passes through an inclined or curved slot, M, in the plate E. and is attached to the end of the lever N, which is pivoted to the plate E by a rivet, O, or other suitable means. The forward part of the lever N is bent upward, so that its lower part will be so low down upon the plate E as to be out of the way. With this construction, by moving the rear part of the lever Ndownward, the lug K will be forced toward the lug J, so that the said lugs will be forced against the sides of the holes L, and will clamp the plate E firmly to the front of the bench A, and by moving the rear end of the lever N upward the lug K will be forced from the lug J and the plate E will be released. 8 5 Holes L are formed in the front of the bench to receive the lugs J K, so that the plateE and its attachments can be move toward or from the forward endof the bench A, as the length of the work to be held may require. The rear 0 end of the lever N passes beneath the lower end of the clamp F, so that the said clamp may serve as a guard to keep the said leverin place against the plate E. The pins or lugs J K should be roughened to prevent them from 9 5 slipping out of the holes Lwhen clamping the plate E against the front of the bench A.

To the rear end of the plate E is pivoted the cam P in such a position as to bear against the upper side of the rear end of the lever N and lock thesaid lever in place when clamping the plate E to the front of the bench A.

In using the improvement, the hook Ois adjusted at the proper height to hold the work, and the 0am I is turned into a vertical position to release the bar D. The bar D is then ad justed into such a position as the length of the work to be held may require, the hook O is drawn into the work, and the cam I is adj ust ed to lock the bar D and hook O in place.

Having thus described niyinvention, I claim as new and desire to secure by Letters Patent 1. The improved bench-hook consisting of the attaching-plate E, provided with the horizontal sliding bar D, mounted in suitable ways in the upper face of said plate, and the vertical hooked bar 0, secured adjustably to said bar D by slots and set-screws O O, and a suitable clamping device on plate E, for holding the bar D in any desired position, substantially as set forth.

2. The combination, with the bench pro vided with holes L, of the attaching-plate E, carrying the bench-hook, and provided on its rear face, near one end,with pin .I, and on its front face, near its opposite end,with a pivoted lever, N, carrying a pin, K, extending through an inclined slot, M, substantially as set forth.

3. The combination of the attaching-plate E, carrying a bench-hook, and provided on its rear face with a pin, J, with thelever N, pivoted to the said plate, and provided with a pin, K, at its forward end, extending through an inclined slot, M, and a clamping-lever, I, pivoted to the attaching-plate at the rear end of said lever, for clamping said lever in place.

at. Iheattaching-plate E, having the horizolr tal bar I), carrying the hook-bar, and sliding in suitable ways innsaid plate, in combination with the clamp F, bearing against bar D, and

mounted on stud G on the attaching-plate, and a cam-lever, I, also on said stud, and adapted to force the clamp against the horizontal bar I) for looking it in place,substantially as set forth.

5. The horizontal bar D, mounted to slide in 5 upper endon said bar D, fLIlClIDOLlDlJGd on a stud, G, on the plate F, said stud also carrying a cam-lever, I, bearing on said clamp I for binding the clamp against the bar andlock ing said bar in place, substantially as set forth.

6. An adjustable bench-hook consisting of an attaching-plate provided near its top with a horizontal bar, D, sliding in suitable ways therein, said bar carrying a vertically-adj ustable hook-bar, C, a clamp, F, on the screw G of the attaching-plate, bearing on the barD, a

cam-lever, I, also on said screw, for operating clamp F, a pin, J, on the rear face of the attaching-plate near one end, and a pivoted le ver, N, carrying a pin, K,working through an inclined slot, M, and a clamp-lever for locking the rear end ofsaidlever, substantially as set forth.
