DRAG-SAW FRAME.

SPECIFICATION forming part of Letters Patent No. 297,558, dated April 29, 1884.

-Application filed January 17, 188-1. (No model.)

To all whom it may concern:

Be it known that we, MAI-ILON BECK and AUSTIN MoRoREY, citizens of the United States, residing at Excelsior Springs, in the county of Clay and State of Missouri, have invented certain new and useful Improvements in OrossoutSaw Frames, of which the following is a specification, reference being-had therein to the accompanying drawings.

Our invention relates to improvements in drag-saw or crosscut-saw frames, the object of which is to provide an easy, convenient, and rapid means of sawing logs and wood, and at the same time to provide a frame for supporting, steadying, and carrying the front end of a saw that is operated by one man, but usually takes two, said frame being light, simple, and durable, and so constructed as to be easily adjusted. These objects we attain by means of the device illustrated in the accompanying drawings, forming a part of this specification, in which- Figure l is a view in elevation, showing the entire device. Figs. 2 and 3 are detailed views.

The distinctive features of our invention consist in an adjustable vibrating shaft supporting one end of a crosscut-saw, and supported in a rocking yoke between two uprights in which the said yokehas bearings, said uprights being rigidly attached to and supported upon the sides of a slot in a horizontal piece, said piece having one end rest upon the log to be sawed, while the other end of said piece is supportedupon adjustablelegs,andothernovel features hereinafter more fully set forth.

A is a drag or crosscut saw having a handle, a, at one end, the other end being attached to a shaft, B, by any suitable device. The shaft 13 is made any desired length and size, and of any suitable material, preferably wood, to make it light. This shaft has holes I) for pins 1) to regulate the height of the saw.

G is a yoke, made of wood, iron, or other suitable material, and to fit closely around the shaft B,which it supports. This yoke is made with arms 9 on each side, to rest and work in suitable bearings, c, in the upright supports 0 O, permitting the said yoke to rock back and forth with the shaft. To facilitate the motion of the shaft, the front and back sides of this I yoke are beveled from above and below 9' to form an edge, g.

C O are uprights, preferably made of wood and firmly attached upon a piece, E, and having a connecting-rod, c, to supportthem more firmly for sustaining the bearings of the yoke.

E is a horizontal piece, also preferably made of wood, and of sufficient size and length to admit of a slot, F, for the shaft B to pass through and vibrate in, and to firmly support the uprights G G on the sides of the said slot.

From the slot F, extending forward, is a narrow slot, f to guide the saw until it enters the log, and by means of a pin, 6, in a hole, e, to fasten the saw up when moving it from place to place, and over this narrow slot is a bar, 6 which has the ends bent down, eX- tended through, and attached in the piece E, to strengthen the same and to hold the saw when moving. The lower ends of this bar e are sharpened to form brads or dogs 0 to hold one end of the piece E fast to the log to be sawed. The piece E has holes 6 e c e for legs D D and set-screws d (I. These legs may be lengthened or shortened by means of the set-screws d (I, so that the frame-piece E maybe set horizontally on sidling and inclined ground. a

The device is operated thus: The front end of the piece E is placed upon a log to be sawed, the brads e are driven into the log, and the legs D D lengthened or shortened to make the piece E level. The pin 6 is removed, and the saw rests upon the log to be sawed. One man by the handle a moves the saw back and forth. The front end, being guided by the frame, cannot wabble, and being drawn on a horizontal line all of the teeth out a full stroke. WVhen the log is cut off, the upper pin, 1), prevents the saw from cutting in the ground. The saw is then raised into the slot f, the pin 6 placed beneath it, and it is then ready to move to another place.

The device, when full size, is very light, weighing only about twenty-five pounds, and

thus may be very easily carried by one man from one log to another, as desired.

. The frame being very simple, there is but very little machinery' to get out of repair, and may be very easily operated by one man.

Having thus described the construction, use,

and operation of ourinvention,what we claim as new, and desire to secure by Letters Patcut, is

1. A erosseut-saw frame composed of a vi brating shaft, B, supported in a yoke, G, between uprights O C, said uprights resting upon a horizontal piece, E, said piece having a slot, F, to receive the shaft, and a slot, f, to re ceive the saw, the front end of said piece resting upon the log to be sawed,and its back end upon legs D, all substantially as shown and described.

2. An improved crosscut-saw frame for supporting the front end of a saw, composed of a vibrating shaft, B, said shaft being made adjustable in height, and supported in a yoke, G, said yoke having bearings in uprights C O, which are stayed upon a horizontal piece, E, said piece having a slot, F, to receive the shaft, and a slot, f, to receive the saw, and a bar, 6 to stay the front end, and adjustable legs D, to support the back end of said frame, all substantially as shown and described.

3. The combination of a saw, A, with a frame composed of a shaft, B, supporting one end of said saw, supported in a yoke, G, having bearings in uprights G C, said uprights supported upon a horizontal piece, E, said piece having a slot, F, in which the shaft vibrates, and a narrow slot, f, said piece resting upon the log to be sawed at one end, and upon adjustable legs D D at the other, all substantially as and for the purpose set forth.

4. In an improved frame for carrying the front end' of a crosscut saw, a vibrating shaft, B, adjusted in height by means of holes I), in which are placed pins b, a 'i' ibrating yoke, G, having arms 9 for bearings, and the front and back sides beveled from below and above g g", forming an edge, and a horizontal piece, E, made with a slot, F, to reeeive a vibrating shaft, and a slot, f, to receive a saw, and having a bar, 0 over the slot f, and made with sharpened ends 6 a pin, 6, passing across the lower part of said slot f, to hold the saw up, the back end of said piece E being supported by means of legs D, adjusted in length by means of thumb-screws d, all substantially as shown and described, for the purpose specified.

In testimony whereof we aflix our signatures in presence of two witnesses.
