UNITED STATES PATENT OFFIC MERVIN OOXE .AN D GEORGE E. COXE, OF GREAT VALLEY, NEWV YORK.

DRAG-SAW.

SPECIFICATION forming part of Letters Patent No. 361.052. dated April 12, 1887.

' Application filed October 12, 1886. Serial No. 216,030. (No model.)

10 simple and durable in construction and effective in operation.

The invention consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1' is a side elevation of our improvement, and Fig. 2 is a plan view of the same.

The frameA, of hard wood or other suitable material, is provided with legs B, which sup-' port the rear end of the bed-frame O, on which are erected the standards D, connected by the 0 braces E are secured the metallic pointed spikes or clamps G. The upper ends of the standards G are united by the curved brace or stay H and the bed-frame (J, and the legs D are strengthened by the braces I and by the A platform, K, is secured to the rear upper end of the bed-frame 0. Near the center of the latter, and on the side edges of the two beams O of the frame 0, are secured the me- 0 tallic guide pIates L, through which and through the side beams, 0, passes a pin or shaft, M, on which oscillates the lever N, connected at its upper'end by the link O,with the crank-arm P, journaled in suitable bearings in the standards D, and provided on each side The operation is as follows: The frame A is placed in the positionshown in Fig. 1, so that the spikes or clamps G are firmly-embedded in the top of the log to be sawed, and the saw-blade S rests in the slot F of the sawguide F. The bed-frame C is thus supported ina horizontal position at one end by the log and at the other end by its legs B. The operator seats himself on the platform K, and

by turning the handles Q, imparts a rotary motion to the crank-arm I, which by means of the link 0 imparts an oscillating motion to the lever N. The oscillation of the lever N causes a forward and backward motion of the saw S, which thus saws the log.

The pivotal connection of the saw-holder R with the lever N permits the saw-blade S to adjust itself to the cut in the'log. The throw of the lever N can be increased or diminished by changing the fulcrum of said lever by 7 means of theapertures N and the pin M.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, i.s'

In a sawing-machine, the bed-frame O, supported at one end by the legs B, the standards D, erected on the said bed-frame, the braces E, connecting the said standards with the bedframe, the slotted saw-guide F on the front end of the said braces E, the clamps or spikes on the under side of the said braces, the metallic guide-plates L, secured to the bed-frame C, and the pin M, journaled in the said guideplates L, in combination with the crank-arm P, journaled in the said standards D and provided with the handles Q, the link 0, connected with the said crank-arm, the oscillating lever N, pivotallyconnected with the said link 0 and fulcrumed on the said pin M, and the sawblade S, pivotally connected with the said lever N, substantially as shown and described.
