IMPROVEMENT IN WOOD-SAWING MACHINES.

Specification forming part of Letters Patent No. 158,055, dated December 22, 1874 application tiled October 3, 1874.

To all whom it may concern Be it known that we, HENRY4 FILLEY and ALANSON D. WOOD, of Hersey, in the county of Osceola and State of Michigan, have invented a new and Improved Wood-Sawing Machine, of which the following is a specifica tion:

The invention will rst be fully described, and then pointed out in the claims.

Figure l is a side elevation of our improved machine; Fig. 2 is a horizontal section taken 011 the line ma.' of Fig.1 5 Fig. 3 is a transverse section taken on the line y y of Fig. 2.

Similar letters of reference indicate corresponding parts.

A represents the saw; B, the rod for working it; G, the cross-head for working the rod; D, the ways for the cross-head E, cams on one side ofthe driving-pulley F, for throwing the cross-head back; and F, cams for throwing it forward, arranged to give two double motions of the saw to one revolution of the driving-pulley. Gr is a vertically-working cross-head in the ways H, for raising and lowering the saw by raising the rod B and allowing it to descend, said rod `working through a slot in the cross-head between rollers H. rlhe cross-head is connected to the endless rope I, which passes over pulleys J, and is connected to the hand-lever K, which is used to raise and lower the saw by moving the cord up and down. lThis lever may also be used to press the sawv into the work, if desired, and is provided with a cord and weight, X, for applying the pressure. L represents the holding-dog for securing the log to be sawed, which is provided with a lever, M, for forcing it into a log and for drawing the log up to its place. A holding-plate, N, is provided with notches to hold the lever after it is adjusted, the levers being arranged to swing into the notches, and its pivot y is adjustable up and down to adjust it to logs of different sizes. O is another dog, which is used by driving int-o thelog in the ordinary way. It is held in a slot in the post by its head Z, and is adjustable up and down. The driving-wheel, F', may be worked by power with a belt, or by hand-crank, P.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The cams E F, arranged alternately, and with reversed curves, on wheel F, to operate the cross-head O, in the manner described.

2. The weighted cord passing over pulley, and the lever K, combined as described, to press the saw to the wood in the manner set forth.
