IMPROVEMENT IN SAWlNG-MACHINES.

Specification forming part of Letters Patent No. 125,975, dated April 23, 1872.

To all whom it may concern.-

Be it known that I, CORNELIUS B. MORE- HOUS, of Washington, in the county of Washin gton and State of Iowa, have invented a new and useful Improvement in Sawing-Machines and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to a new and useful improvement in machines for sawing fire-wood and for other purposes; and it consists mainly in an automatic feeder, in combination with one or more saws, the combination and arran gelnent being as hereinafter more fully set forth and described.

In the accompanying drawing, Figure 1 is a side elevation, and Fig. 2 a top or plan view of a sawing-machine constructed according to my invention.

Similar letters of reference indicate corresponding parts.

A is the sawing frame or table, of rectangular orio ther form, and of suitable size. B is the drivingshaft. 0 is the saw shaft, with one or more saws thereon, revolved by means of the belt D from the pulley E of the shaft F. G is a pinion-wheel on the shaft F, and H is a cogged wheel on the driving-shaft which engages with the pinion-wheel. I is a crank on the driving-shaft. The machine may be driven by hand-power applied to the erank,or by any other motive-power. end of the shaft F. K is a small pinion on the end of the driving-shaft B, which shaft extends to about the middle of the table, and is supported by the boxes L L. M is a spurwheel, which en gages with the pinion K. This wheel is on a short shaft supported by the table-top in the box N. O is the feeder, which is made to slide horizontallyin suitable guides J is a fly-wheel on the.

on the table and push or force the woodto be sawed up to and through the saw or saws. I is a pitman connected with the feeder, as seen at q, and with the spur-wheel M, by a wristpin, R. The small pinion and the large spurwheel give the feeder a motion proportioned to the speed and power imparted to the saws. S represents the saws, one or more of which may be employed. T represents curved bars of iron hinged or pivoted to the front of the feeder,-serrated on their inner edges, the object of them being to hold the piece of wood while being sawed.

The arrangement of the feeder is such that it is drawn back sufficiently to receive the wood to be sawed back of the saws, on the return or forward motion, to force it over and through the saws. To the front edge of the feeder three (more or less) bars, U, are hinged. The piece of wood to be sawed is placed on these bars when the feeder is drawn back. When the feeder has been forced forward past the saws these bars drop and discharge the sawed wood. As the feeder is drawn back these bars are drawn up so as to again be parallel with the table. Vith this machine all that it is necessary to do is to place the wood on the machine. All the labor and danger of forcing it up to the saw are avoided.

Having thus described myinvention, I claim as new and desire to secure by Letters Patcut-- 1. The feeder O U, in combination with the sawing-machine herein described.

2. The combination and arrangement of the shafts B and F, pinions G and'K, wheels H and M, feeder 0, saw or saws S, and table A, substantially as and for the purposes dedescribed.

CORNELIUS B. MOREHOUS.
