BENCH-CLAMP.

Specification of Letters Patent.

Patented Nov. '7', 1916.

Application filed June 24, 1914. Serial No. 847,063. 1

To all whom it may concern Be it known that 1, JAMES M. BRILES, a citizen of the United States, residing at Victoria, in the county of Victoria and State of Texas, have invented certain new and useful Improvements in Bench-Clamps, of which the following is a specification.

The object of this invention is to provide a bench clamp having one or more grips for engaging the work at different elevations so that if it is desired to plane or otherwise finish or dress a flat side of stock, one of the grips may be used to engage the stock adjacent the surface of the bench, and if it is desired to plane or dress ,a side edge, then both of the grips may be adjusted to engage the stock at different elevations and hold .it in an upright position with its edge in an exposed relation for engagement by the dressing tool.

It is a special object of my invention to simplify bench clamps and provide means whereby the upper grip may be moved out of an operative position and out of a position above the surface of the bench when not in use. 7

Other features of novelty will be more fully described in connection with the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawing :Figure l is a perspective view showing one form of the device of my invention with the upper and lower grips in an operative position. Fig. 2 is a view looking from the rear of Fig. 1. Fig. 3 is a plan view showing the upper gri s ad-v justed out of an operative position. ig. 4 is a side view showing the position'of the upper and lower grips when the upper grip is adjusted out of an operative position.

Like characters. of reference designate similar parts throughout the different figures of the drawing.

As illustrated 1 designates a bench on which a lower or surface grip 2 is preferably rigidly mounted to grip the work. The grip 2 is provided with a base 3 which lies flat upon the bench 1 and which may be secured thereto by means such as screws 4:. The grip portion 2 is elevated somewhat with respect to the surface of the bench, as will be clearly seen by reference to Figs. 1 and 4, and the work-engaging end of the surface grip 2 is preferably serrated or toothed, as indicated at 5. I also bifurcate the lower or surface grip as indicated at 6 for insertion between the bifurcated portions of work of that character to" be held edgewise. In order to stiffen the lower or surface grip I preferably flange the same at 7 so as not only to extend the area of engagement with-the work when the latter is dlsposed edgewise between the jaws of the bifurcated portions, but also to permit of forming the surface grip of sheet metal and imparting sufficient rigidity thereto by its formation to withstand the stresses imposed thereon. The lower or surface grip is extended beyond the edge of the bench 1 and is bent to form butts 8 into which a pin 9 is adapted to be extended.

I provide an upper grip which comprises a strip of metal composed of an upright portion 10 and a horizontal portion 11. The terminal .end of the horizontal portion 11 is bifurcated, as indicated at 12, and I flange the inner faces of the bifurcated portion as indicated at 13, to stiffen the upper grip. The upper grip is hinged to the bench by means which may comprise an an choring plate 14 provided with butts 15 through which a hinge pin 16 extends. The lower end of the upper portion 10 is bent to form a knuckle 17 whereby the upper grip will be hinged to the bench in a manner which will now be clear.

The upper grip, or the upright portion 10 thereof, is proportioned to lie between the butts 8, when in an operative position, and to 'be anchored in. an operative position by the pin 9. I

It will be seen from the foregoing construction that the upper grip can be readily locked to the lower grip in an operative the lower and upper grip will be in such vertical alinement that the work can be disposed edgewise as shown in Figs. 1 and 3 for operation on the upper edge thereof. If on the contrary, the workman desires to operate upon one of the sides of the work, the locking means of pin 9 can be removed so that the upper grip can be detached and swung into an inoperative position thereby leaving the area above the lower grip free for operation upon the work in a flat position, as shown in Fig. 3.

It is believed that the advantages and utility of my invention will be clearly understood from the foregoing description and while I have herein shown and described one position so that the bifurcated portions of specific form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim 1. In a bench clamp, a bench, a lower work grip anchored to the bench for engaging the work at the surface of the bench, an upper grip hinged to the bench for engaging the work at a point above the surface grip, and means for locking the upper grip to the lower grip and disposing the upper grip in an operative position, substantially as described.

2. In abench clamp, a bench, a lower grip I formed of sheet metal and anchored to the bench and provided with a toothed edge and,

a bifurcation extending from the toothed edge, a sheet metal upper grip hinged to the bench and provided with a bifurcated portion adapted to be disposed in vertical alinement with the bifurcated portion of the lower grip, and means for locking the upper grip in an operative position and to the w lower grip, substantially as described.

8. In a bench clamp, a bench, a lower grip anchored to the bench and provided with 7 means for engaging the work at the surface of the bench and having butts extending from the bench, an upper grip hinged to the bench andadapted to be'moved into an opform a work-grip jaw, the bifurcated portion being flanged to fit the same and provide a relatively wide area for grip of the work, an upper grip hinged to the bench and provided with a flange bifurcated portion adapted to be disposed above the bifurcated portion of the lower grip, and means for locking the upper grip in an operative position, substantially as described;

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