B. OWEN,
Improvement in Sawing-Machines.

UNITED STATES PATENT OFFICE.
BENJAMIN ownn, on DAYTON, 01110.
IM PROVEMENT IN SAWlNG-MACHINES.
Specification forming part of Letters Patent N 0. 128,420, dated June 25, 1872- lation to the swinging frame and the racks.
This drawing in scale is twice that of Fig. 1.
A represents the saw-frame, which is constructed in the usual manner. To the rear of the frame'are' secured the arms Gr, one on each side of the frame. These arms are provided with pivots for the ends of the frame B, and the centers of which form bearings for the counter-shaft. The dotted lines at H show the position of the pulley on the counter-shaft. A belt connects this with the pulley on the sawmandrel. To the forward part of the frame are secured segmental racks D, one on each side having a series of cogs in front, and an aperture extending nearly the entire length of the racks. The swinging-frame B is constructed in the usual manner, having projecting parts, shown by dotted lines at m, which serve as bearings for the saw-mandrel. To the front and under side of this frame are secured the hangers B and B that of B being on the near side, and B on the opposite side. Thesehangers form the bearing for the shaft of the pinions F on each side, and support the tightening rod E at each end. The pinions gear into the rack, and outside of the near pinion the shaft terminates in a square end for the orifice of the crank I. (See Fig. 2.) By means of the crank the pinions are made to rotate, and thus the saw is carriedup or down, as may be de sired. The tightening-rod E, Fig. 2, has a screw on each end. The screw on the left end enters a female screw in the part B and the screw to the right enters the nut L. This nut has a flanged part, which rests against the side of the frame, and the other part rests loosely within the aperture of the rack, which prevents its turning. The head E is flanged and terminates in a square for the crank. The rod passes through the aperture of the rack, and the opposite end passes through a circular orifice in the part B. The pinion-shaft and tightening-rod are both operated by cranks at the same time, one being operated by the 'right and the other the left hand. 0n turning the crank to the right the rack is clamped between the head E and part B, and the nut L is brought tightly against the rack on the opposite side; this looks the swinging frame and holds the saw at any desirable elevation. A counter movement releases the frame.
I claim as my invention- The combination and arrangement of the rod E, nut L, hangers B B pinions F, racks D, and swinging circular-saw frame B, substantially as described.
-BENJAMIN OWEN.
