IMPROVEMENT IN SAW-BUCKS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY J. DILL, of Cummngton, in the .county of Hampshire, and State of Mussucliu` setts,` have invented a new and useful Improvement in Saw-Bucks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification.

This invention relates to the manner in which a stick ot' {ire-wood or cord-wood is held fast or secured in the saw-buck for the purpose of sawing it into suitable lengths; undfit consists in arranging adjustable toothed clamps for holding the stick, which clamps nre brought in contact with it by bearing upon a treadle with the foot, and which clamps are thrown apart by the action of springs, as will be hereinafter described.

Figure 1 represents a side view of' the saw-buck with the clamps attached. l p y Figure 2 is an end view, showing more distinctly theditl'erent parts, andthe manner oftheir combination.

Similar letters of reference indicate corresponding parts. p

A represents the stands of an ordinary saw-buck, connected `together by the bar B in the usual manner. They 'are also connected by another bar or rod at their lower ends, which rod is marked C. D represents the clamps. There are two of these, as seen in the drawing, each formed of two pieces, which :1re halved together where they intersect each other, and with the bar B passing through them, as seen, which bar forms a pivot, l

upon whichthey hang, and turn or open and shut like a pair of shears. Each of those clamps has an arm, E, which is fast to one leg, and which passes through. a mortise in the other leg, as seen, and around this arm there is a spiral spring, F', the tension of which tends to keep the legs apart.' In order to draw them together, and thereby bring the jaws together, a treadle, E', is attached tothe lower bar or rod, C, by a hinge, a. F represents rods, which are attached to each of the four legs ofthe clamp by staples, the endsof which rods are attached to rings, as seen in the drawing. Theserings support a rod, over which the trendle passes, and which is depressed by bearing or pressing upon the treadle, and raised by the action of the springs, when the pressure upon the treadle is removed. In this way 'the clamps are made to gripe a stick of wood, as seen in `ig.'2. Gr represents the wood. For the purpose-of holding the wood more firmly, thejaws of the clamps are provided with teeth or spikes, which penetrate the wood when the jaws approach each other, and hold it fast. I

Having thus described my invention= I claim as new, and desireto secure by Letters Patent- The clamps D, the treadle E', the arms E, springs F', sind rods F, constructed, arranged, and operating,

in combination with the stationary part A, substantially as shown und described, for the purpose set forth.
