BENCH-STOP.

SPECIFICATION forming part of Letters Patent No. 349,881, dated September 28, 1886.

Application filed March 25, 1886.

To all whom it may concern.-

Be it known that 1, GEORGE B. GARDNER, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and Ill)- proved Bench-Stop, of which the following is a full, clear, and exact description.

My invention relates to work-holding stops for benches used by carpenters and other woodworkmeu, and has for its object to provide a simple, inexpensive, effective, and readilyadjustable bench-stop by which work may be held either at the top or side of the bench, and whereby two men may use the same side of a bench while engaged on separate pieces of work.

The invention consists in certain novel features of construction and combinations of parts of the bench stop, all as hereinafter fully described and claimed. a

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 a perspective view of part of a work-bench with my improved stop applied thereto and illustrating its use. Fig. 2 is an inner face view of the stop removed from the bench. Fig. 3 is a vertical sectional elevation of the stop and adjacent parts of the bench, and Fig. 4 is a top view of the work-holding dog removed from the stop.

The main plateA of the bench-stop is provided at its outer face and upper end with a lug, a, which is vertically apertured to receive the shank b of the work-holding dog B, and a spring, I), held to the shank 1), holds the dog where set at any required height above the top of the work-bench G to suit the thickness of the lumber being worked. I make the dogB with end parts, B B which project opposite ways from the main body portion of the dog, and are toothed at their extremities to catch in and hold the lumber on the top of the bench O, as hereinafter more fully explained.

At the front edge of the plate A is cast a rib, a, on which are fixed the toothed lugs D D, which form dogs adapted to catch into and hold the back end of a board clamped at its forward end to the side of the bench by an ordinary bench-vise, E, as presently described.

On the back of the main plate A there are cast a couple of lugs, F G, having vertically- Serial No. 196,536. (No model.)

ranging slots, in which the toothed grips or clamp-plates H I are fitted to slide, and to these grips, respectively, are attached the one ends of links J K, the other ends of which are pivoted to the opposite ends of a plate, L, which is journaled at its center by a stud, Z, in the mainplate A. To the outer squared end of the stud l alever, M, is fitted, and when this lever is raised the grips H I will be drawn toward each other, and when thelever is lowered the grips will be forced apart.

To the side of the work-bench C there are fixed in any suitable way a pair of parallel guide-strips, N O, the opposing edges n o of which are preferably undercut, as shown clearly in Fig. 3. The back lugs, F G, of the plate A fit between these guide-strips N O, and the toothed ends h t of grips H I enter the edges n 0 of the strips when the lever M is lowered.

The operation is as follows: In surfacing stuff, such as a panel, P, placed 011 top of a work-bench, 0, provided with an end vise, R, having a stop, 1", the benclrstop plate A will be set up to the side of the bench withits lugs F G between the guide-strips N O, and while the lever M is held raised the plate A will be adjusted so that the end B of the dog B stands a little behind the back end of the panel, while thejaw of the vise R, which carries the stop 1', is screwed away from the forward end of the bench O, and the lever M then will be lowered to drive the grips H I into the strips N O, and thereby hold the dog B firmlyin place. The back end of the panel P will be forced back to catch onto the end B of the dog B, and the vise It will be operated to force its stop r against the forward end of the panel P and clamp it firmly between the stop 1' and dog B, as shown in Fig. 1, to hold the panel so it may be planed, carved, or otherwise worked by' tools cutting in any direction. When the bench O is not provided with the end vise and dog, R 1', but has a common fixed head-stop against which the forward end of the work will be forced, and in every case when the work being planed or operated upon varies considerably in length, the lever M will be raised to allow the plate and dog A B to be pushed forward until the end B of the dog catches into the back end of the stuff, and the lever M then will be lowered to clamp the plate and dog A B to the strips N O for holding the work, and

may be edged by a plane or cut by a. drawshave or other tool in either direction. The double-toothed end B B on the dog B of the bench-stop not only allows the stop to be set at the extreme forward end of the bench to hold the work by its toothed end B, but this double-toothed end B B on the dog, together 'with the grips H I and their operating devices above described, allows the bench stop to be anywhere along the center of the length of a. work-bench, whereby the end B of the dog may hold the back end of a piece of work, P, as above explained, and the end B of the dog may be used to support the forward end of a piece of Work, T, (shown in'dottedli'nes in Fig. 1,) thus allowingtwo men to work at the same side of the bench, which at times would beadvantageous.

The bench-stop may be made cheaply, and may be conveniently carried with a kit of'tool's, so as to be at hand for use on temporary workbenches of any kind, as will readily be under- .StOOd.

grips fitted at the baekof the plate and adapted to be forced into guide strips fixed to the side of awork-bench, and dogs, as at D, at the front edge of the main plate and adapted to hold the back end of work clamped to the side of the work-bench, substantially as herein set forth.

2. The combination, in a bench-stop, of a main plate, A, provided with a slotted lug, a, a dog, B, having a shank, b, fitted in the lug a, and having a toothed body portion adapted to overlap the top of a work-bench, dogs, as

at D, at the front edge of plateA and adapted 'to hold the back end of the work at the side of a bench, and devices adapted to clamp the plate A to the side of the bench, substantially as herein set forth.

3. The combination, in a bench-stop, of a main plate, A, having a slotted lug, a, a dog,

l-B, having a shank, b, fitted in lug a, and pro- 1 vided with a toothed body portion adapted to .overlap the top of a workbench, grips H I,

fitted at the back of plate A and adapted to clamp guide-strips fixed atthe side of a. work.- bench, linksJ K,attacbed to grips H I, a plate,

L, pivoted to plate A and also to links J K, and a lever, M, connected to plate L, substantially-as and for the purposes herein set forth.

4.. In combination, a work-bench provided v with guide-strips N O at the side, and a benchstop comprising a main plate, A, gripsH I, fitted thereto and adapted to clamp the stop to the strips N 0, links J K, pivoted plateL, a lever, M, connected to plate L, and one or more'work-holding dogs fitted to plate A, substantially as herein set forth.

5. In a bench-stop, the combination, with a main plate, A, held adjustably to the side of a work-bench, of a dog, B, fitted in plate A and bent over the top of the bench and provided with oppositely-extending extremities B B, adapted to hold the work, substantially as herein set forth.
