APPARATUS FOR SAWING WOOD.

SPECIFICATION forming part of Letters Patent No. 756,917, dated April 12, 1904. Application filed January 16, 1904. Serial N0.189,285. (No model.)

To all whont it may concern:

Be it known that I, WILLIAM R. WALKER, a citizen of the United States, residing at Fort Smith, in the county of Sebastian and State of Arkansas, have invented an Apparatus for Sawing Wood, of which the following is a specification.

This invention is an improvement in sawingmachines, and relates more especially to the class of portable apparatus for sawing firewood into suitable lengths.

- The primary object of the invention is to provide a saw-carrying frame or apparatus for the purpose of suspending a crosscut-saw at one end of the latter and in such manner that the said saw may be conveniently and easily operated by a single person.

A further object of the invention is to so construct and arrange the parts of the sawcarrying frame as to assist the operation by automatically returning the saw after each stroke.

Other objects of the invention are to provide an apparatus of this character which shall be simple in construction, light and durable, may be conveniently moved from place to place, and will greatly reduce the labor usually required to operate a crosscut-saw such as used in connection with my improved apparatus.

The following specification enters into a full description of the construction and operation of my invention, and what I claim as new, and desire to secure by Letters Patent, is more specifically set forth in the appended claims.

In the accompanying drawings, which form a part hereof, Figure 1 is a perspective view of an apparatus for sawing Wood constructed Fig. 2 is a detail view of the swinging bar to which the saw is directly connected. Fig. 3 is a longitudinal vertical sectional view through the forward part of the frame.

Similar letters of reference indicate similar parts in all the views of the drawings.

In carrying out my invention I employ a frame consisting of the base-board A, to which are firmly secured two pairs of uprights a (t and a a, the uprights of each pa1r being connected at the1r upper ends by a cross-piece (1,

and rod a and in practice I prefer that the uprights a, which are'located at one end of the board A, be a little shorter than the companion uprights a. Extending between these pairs of uprights, at the upper end thereof, are longitudinal strips a, forming the top of the frame and provided adjoining the uprights a with a cross-piece a This frame is adapted to support the saw in the manner hereinafter described, and in order that the same may also form a support for thelogs or other material to be sawed strips a are disposed diagonally and secured to the base-board A and uprights a, projecting at their upper ends a slight distance beyond the latter and so as to provide a log-rest after the manner of the ordinary sawbuck and at this point the frame is braced by means of a cross-bar (0 as is usual.

B designates a bar which is pivoted near its upper end upon a cross bar or bolt (0 supported between the uprights a of the frame, and to said bar at a suitable distance below its pivot is connected the rear end of the saw C, which latter is the crosscut-saw, usually re-' quiringtwo persons to operate it, one at either end, being a longstraight blade with the teeth at the lower edge thereof. Said saw extends from the swinging bar forward in the frame between the uprights a and above the crossbar (6 thereof and at its forward end is provided with a handle 0, by which it is operated. For the purpose of attaching the saw to the bar B the latter is slotted, as at 6, and the connecting-pin o is passed through a transverse aperture in said bar, several such apertures being provided, so that the radius of movement of the pivot end of the saw may be varied. The swinging bar is held at the cenreturn the saw after each stroke, as is obvious.

At the end of the base-board A opposite the sawbuck is a vertical post D, suitably I00 braced by the pieces cl, and in the upper part of this post is a vertical series of apertures 6?, into any one of which is secured a rod 6, extending therefrom through the frame and attached at its forward end to the crossbar cf, the said rod passing through a slot If in the lower end of the swinging bar B, and in operation the said bar will contact with the rod and limit the movement of the saw, and for which purpose the rod is adjustable upon the post by means of the aforesaid series of apertures d Secured to one of the uprights a at a suitable distance above the sawbuck is a short wooden peg or pin f, the upper edge of which is recessed and V-shaped. This peg or pin is for the purpose of, supporting the saw while the operator is placing a log upon the sawbuck.

and being shaped as shown will prevent the saw from being accidentally displaced. 1 The operation of the apparatus will be readily understood, for after placing a log on the sawbuck the saw is removed from its support fand grasped by the handle 0, being then reciprocated back and forth in the usual manner and the rear en wung by means of the bar B and guided by the rod 6, which latter not only limits the reciprocal movement of the saw, but also prevents any lateral movement of the rear end thereof. It will be seen, therefore, that the saw is manipulated by a single operator in the manner usual with two operators. The spring D will assist in the operations of the saw; but in some instances I may dispense with the same.

Having thus described my invention, I claim 1. In an apparatus for sawing wood, the combination, of a frame, a bar pivoted therein to swing longitudinally thereof and provided at its lower end with a slot, a saw-blade pivoted at one end in the bar above said slot, and a guide-rod vertically adjustable in the frame and passing through the slot in the swinging bar, substantially as shown.

2. In an apparatus for sawing wood, the combination, of a frame, a bar pivoted therein to swing longitudinally thereof, and provided at its lower end with a longitudinal slot, a sawblade pivoted in the bar and provided at its opposite end with a handle, a post at one end of the frame, and a rod adjustably attached to the post, extending therefrom through the slot in the swinging bar and attached atits other end to the forward part of the frame.

3. In an apparatus for sawing wood, the combination, of a frame, a bar pivoted therein to swing longitudinally thereof, said bar being provided at' its lower end with a longitudinal slot and at its upper end projecting above its pivot, a spring connected to the upper end of the bar and to the frame, a saw-blade adjustably pivoted in a slot in the bar and at its other end provided with a handle, a rod vertically adjustable in the frame and passing through the slot at the lower end of the bar, a pin on the supporting-frame for supporting the saw, and a sawbuck forming part of said frame.

4. In an apparatus for sawing wood, thecombination, of a frame comprising a base-board I and two pairs of uprights connected at their upper ends, a bar pivoted between one pair of uprights and having a slot near itslower end, a

saw-blade pivoted ,at one end in said bar and extendingtherefrom through the frame between the other pair of uprights and provided with a handle, inclined pieces secured to the latter uprights to form a sawbuck, a supporting-pin for the saw secured above the sawbuck to one of the uprights thereof, a post at the end of the frame opposite the sawbuck,

and a rod secured to said post and sawbuck, and said rod passing through the slot in the lower end of the swinging bar to which the saw is.connected; together with a spring connected to the swinging bar, substantially as herein shown and described. 7

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM R. WALKER.
