IMPROVEMENT IN SAW-BUCKS.

Specification forming part of Letters Patent No. 169,343, dated November 2, 1875; application filed October 22, 1874.

' To all whom it may concern:

A Philadelphia, Pennsylvania, have invented an Improvement in Saw-Buck, of which the following is a specification:

The object of my in vention is to make cheap and substantial saw-bucks, which can be readily taken apart andpacked in a small compass for transportation and storage, and as readily put together; and this object I attain in the manner. which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure 1 is a perspective view of my improved saw-buck Fig. 2, a perspective view of the legs where they are fitted together; and Fig. 3 a sectional view showing the manner of securing the legs of the buck together and to the cross-bar.

The saw-buck consists of the two legs A and A, and two similar legs, B and B, the two pairs of legs being connected together by the bar D, and the legs being extended above this connect-ion, as usual, so as to form a proper lodgment for the log to be sawed. The two legs of each pair are not halved together in the ordinary mannerthat is, by making a rectangular recess in each leg, where the two cross each other; for these recesses, having abrupt corners, tend to seriously weaken the legs-a difficulty which I obviate by rounding the bottom of the recess in one leg A and making a concave recess in the leg A, as

shown in Fig. 2. The leg A is not materially weakened by its recess, nor'is the leg A weakened, as its recess presents no abrupt corners to induce a fracture. The connectingbar D is reduced in diameter at each end, where it passes through the two legs, and the portion thus reduced in diameter is made plainata, to fit snugly in the opening of the inner leg B, and is threaded at b to accord with an each other, and then one end of the bar D is passed through the plain opening in the inside leg, and screwed into the threaded opening of the outer leg, so that the shoulder as on the bar D shall bear against the inside of the inner leg, when the tighter the bar is screwed the more firmly will the two legs be secured to each other and to the bar, the opposite end of which is connected to the other pair of legs in a similar manner.

I claim as my invention The combination, in a saw-buck, of recessed legs A A, and a connecting-bar, D, having at each end a shoulder, as, and a cylindrical projection plain at a, where it passes through the inner leg, and threaded at b, where it passes through the outer leg, all as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the preseuceof two subscribing witnesses.

HENRY DISSTON.
