CLAMP.
SPECIFICATION forming part oi' Letters Patent Nip. 307,439, dated November 4, 1884.
Application filed March 15, 15354.` (No model.)
sachusetts, have invented a certain new and.
useful Improvement in Clamps. of which the following is a description sufficiently full,
clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the saine, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is an isometrical perspective view of my improved clamp, Fig. 2, a side elevation showing a modification ofthe same, Fig. 3, an end elevation of the head-stock in Fig. 2, Fig. 4, an end elevation of the head-stock in Fig. l, Fig. 5, an end elevation of the slide, and Fig. 6- a vertical longitudinal section of a portion ofthe head-stock in Fig. 2.
Like letters of reference indicate corresponding parts in the different gures of the drawings.
My invention is designed as an improve nient 011 the clamp secured to lnie by Letters Patent of the United States, No. 292,207, dated January 22, A. D. 1884; and it consistsin the employment of a slide of peculiar construction provided with a set-screw, in combina tion with the parts shown and described in said patented clamp, whereby one head-stock is enabled to serve for several bodies, thereby reducing the aggregate cost of manufacture when several of the clamps are required, and rendering the implement more useful and et'- fective than those of ordinary construction.
rPhe nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.
In the drawings, A represents thc body of the clamp, I3 the head-stock, and G the tailstock. The body is provided on either side with a longitudinal groove, m, ruiming its entire length, and on its top with two series of holes, g 71,. The head-stock consists of two downwardly-prejecting flanges or side pieces, E, which are connected by the horizontallyarranged cap or body F, the body of the stock being provided with two upwardlyprojecting l flanges, G G, and either side piece with an inwardly-projecting stud, d, working in the groove m.
Mounted horizontally in the head-stock B,
and fitted to work in correspondingly-thrcaded holes, b, in the flanges G, there is a screwshaft, J, provided with the handle or lever L at its outer end, the shaft being engaged with both flanges, thereby gaining greater strength and directnessof movement than would result from its engagement with a single flange. I do not, however, conne myself to the use of both flanges, or to threading the holes in both when two are used, althoughI deem two preferable to one, for the reasons stated.
The tail-stock C consists of two downwardly-projeeting flanges or side pieces. M, connected by the cap or body N, the body of the stock being provided at its inner end with an upwardlyeprojecting flange or face-plate, Q, and with a brace, t, resting en the body and abutting against the outer face of the flange. The holes g incline slightly toward the center of the body A, the holes h being also inclined toward the center of the body, or in a direction opposite that of the holes g.
The head-stock and tail-stocl are each provided with a centrally-arranged downwardlyprojecting stud, Z, the stud in the head-stock being properly inclined and otherwise adapt ed to enter the holes g, andthe stud in the tailstock fitted to enter the holes h, thereby enabling the stocks to be secured in any desired position on the body.
In Fig. 2 a modification of the clamp is shown, which is preferable for some kinds of work, the modification being described as follows:
Projecting downwardly and backwardly from the forward ends ofthe side pieces E of the head-stock B, and on the inner face of either side piece there is a tooth or dog, P, adapted to enter a corresponding niortise or slet, z, cut in the side of the body A, the slot inclining toward the tail-stock end of the clamp, as shown. A like tooth or dog, P, projects downwardly and backwardly from the tail-stock C on the inner face of either side piece M, adapted to engage in a series of inortises or slots, y, also formed in the sides of the tailstock and slide K, and the tail-stock Yany desired position.
the body A, but inclined toward the head- 1 moved from the body 'for use with another 45 stock end of the clamp, or in an opposite direction to the niortise e.
In using the clampshown and described in said Letters Patent, and also ordinary clamps ot' this character, for `gluing up cabinet-work and similar purposes, it is necessary to leave the work in the clamp until it sets, thus necessitating the use of a head-stock to each body.
My presentinvention is designed to obviate this object-ion, and to that end I make use ot' the slide K, which is inortised to fit nicely on the top ofthe body A, and provided on either side with an inwardly-projecting flange, @,working in the groove m, and also on its top with the vertically-arranged flanges or face-plates RS, as shown. The slideis also provided with a set-screw, T, whichis fitted to work in a correspondingly-threaded hole, i', and engage the body A, thereby enabling it to be secured in In the use of my improvement the body A is placed on any convenient bench or support, and its head-stock adjusted as shown, the pin lof said stock being in one of the holes g, and the stud d in the grooves m. The 'work to be glued or' otherwise operated on is then placed lacross the top of the body or stock A, between moved up as closely as possible to the article to be clamped, the studs dof the tail-stock being also in the grooves m. The pin or stud Zin the tail-stock is then pushed down .into one of the holes 7i, and the screw J turned in by the handle L, causing the work to be grasped or clamped between the slide K and tail-stock C in a manner which will be readily obvious without a more explicit descript-ion. After the work is clamped between the tail-stock and slide, as described, the screw T is turned Idown forcibly onto the body A, l thereby rinly securing the slide in the position in which it stands at the time. The screw J is then'turned back and the headstock reclamp.
For doing small work two or more slides may be used with each clamp, if necessary. It will also be .obvious that when a piece of work is clamped between the tail-stock C and slide K, and the slide secured by the screw T, another piece of work may also be clamped between the head-stock and slide, if desired. A loose guard or cap, H, is titted to the inner end of the screw to prevent injuring the work. This, however, will not be required unless the work is clamped between the head-stock and slide. The pins l and teeth or dogs P, being inclined and respectively hooking into corresponding holes or mortises in the body A, prevent the inner ends of the stocks fromrising or riding upwardly when a great strain is exerted 4on the screw J, or in doing heavy work. The stocks being respectively pivoted on the studs d, their inner ends may be readily raised to enable the work to be inserted to better advantage.
Instead of the flanges e, the slide may be provided with a stud on either side projecting into the grooves in, if preferred.
I-Iaving thus explained my invention, what I claim is- Y I. Ina clamp substantially such as described, the slide K, provided with the flanges e and screw T, in combination with the body A, tail-stock C, head-stock B, and screw J, construeted, combined, and arranged to operate substantially as specitied.
2. In aclamphavingaheadstoek, tail-stock, and body, substantially such as described, the slide K, provided with the face-plates R S, screw T, and ilanges e, substant-ially as set forth. r f
