IMPROVEMENT IN JOINERS CLAMPS.
Specification forming part of Letters Patent No. 153,206, dated July 21, 1874; application filed February 24, 1874.
To all whom it may concern:
Be it known that I, CORNELIUS S. VAN WAGONER, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in J oiners Clamps, of which the following is a specification:
My invention relates to an improvement in what is known to the trade as joiners7 clamps, particularly to that class which have a movable or adjustable arm, on the end of which is 4a screw; and the invention consists in forming the mortise in the arm, where the beam passes through it, of such a shape as to bring the bearing-points thereof nearer together, and
consequently nearer to the central axial line of the arm.
Figure l is a side elevation of a clamp embodying my invention. Fig. 2 is a central vertical section of the same. Fig. 3 is an under-side view of the arm. Fig. 4 is a section through the line a b in Fig. 3.
A is the beam, provided with central side ribs f, curved at its lower end, provided with a fixed jaw, g, at its bottom, and a cap, O, at its top. A cross-section through the beam A on the plane of line 1/ y, Fig. l, will give the cruciform shape shown at J in Fig. 3. B is the arm, one end of which is provided with a binding-screw, C, having an adjustable head or presser-plate, Vh, between which and the lxed jaw g any object, E, is held and compressed. The part L of the arm B is enlarged ,and perforated with an opening, J, of a crucilform shape, as shown in Fig. 3, and in size a little larger than the beam A, so as to slide easily up and down the latter when held at right angles to it, or in the position shown in Fig. l. The sides of the opening J in the arm B are not made parallel all the way through,
as in the usual manner. The two lower lefthand central corners are cut away at a bevel, as shown in Figs. 3 and 4:, up to about the center of the arm, as shown at c to a in Fig. 4., and the two upper right-hand central corners are cut away in a similar manner, as shown at b to b in the same ligure. The lower lefthandend c of opening J is also cut away at a bevel, as shown at t n in plan in Fig. 3, and in section in Fig. 4, while at el it is not cut away. Cutting awaylthe bottom of the opening at t 'n gives a double hold or gripe to that part of the arm, making it less liable to slip on the beam than when it presents a plain at surface parallel to the back of the beam. i.
It will been that when an object, E, is placed upon the xed jaw g, in order to hold it there preparatory to tightening the screw C, we have only to push the arm B, slightly inclined, down the beam A, until the object E is held in place, as shown in Figs. 1 and 2, when it may be further compressed by turning` the screw C to any extent required. One or two reverse turns of the screw C will loosen the hold or gripe of the arm, so that it can be pushed higher up the beam, to release one article from the clamp or to insert another.
I claim as my inventiony The clamp-arm B, provided with the mortise J, and having bearing-points a b and upper and lower bearing-surfaces c d, in combination with the beam A, having side projections f, all constructed and operating as and for the purpose herein set forth.
