SAWING-MAC HINE.

SPECIFICATION forming part of Letters Patent No. 367,958, dated August 9, 1887.

Application filcd March 29, 1887.

- thetown of Oartersburg, eountyof Hendricks,

and State of Indiana, have invented certain new and useful Improvements in Sawingdl Ia chines, of which the following is a specification. The object of mysaid inventionis to provide a cheap and simple sawing-machine, which is capable of being folded together in a very compact form, and thus being very convenient to carry from placeto place, as will be hereinafter more particularly described.

Referring to the accompanying drawings,

which are made a part hereof, and on which,

similar letters of reference indicate similar parts, Figure 1 is a perspective View showing one of my sawing-machines'in use; Fig. 2, a side elevation of the same in folded position, the position of its parts while being folded being shown in dotted lines; Fig. 3, a front elevation of the same when folded, the saw being indicated by dotted lines in the position it oeeupie's when the machine is ready for transportation; and Fig. 4 a rear elevation of the machine in its folded position.

In said drawings, the portions marked A represent the uprights or frame of the machine; B, a pendulum; O, braces, which may act as guides; and D the saw.

The frame A preferably consists of four uprights pivoted together at their upper ends on a pivot, a, which also serves as a pivot for the pendulum. The two front uprights are arranged parallel to each other and connected at their bottom to a foot-piece, a, which is of sufficient length to afford a suitable support for the machine. The two rear uprights are preferably flared from top to bottom and connected about midway by a cross-bar, A, bolted to each.

The pendulum '13 is pivoted at its upper end on the pivot a, as before stated, and is adapted to swing freely between the two sets of uprights when the machine is in position for use. At its lower end it is provided with a series of holes, I), by which it is adapted to be connected to the saw by means of a bolt, 12, as shown.

The braces G are arranged a sufficient distanee apart to allow a suitable way for the travel of the pendulum between them, and are preferably bolted together at their forward ends, as shown, and are pivoted between the Serial No 232,859. (No model.)

forward set of uprights, A, on a bolt, 0. On their outer ends they are provided with notches c, which engage with notches a in the edge of the cross-bar A, and thus securely hold the two sets of uprights in position for operation when the frame is opened. These braces, as will be readily understood, maybe made of any length desiredand provided with numerous notches, and the distance between the two sets of uprights thus regulated to suit the work to be performed. 7' r The operation of my said invention is as follows: Themachine is placedin position for use, as shown in Fig. 1, the two sets of uprights being braced apart and secured rigid in-position by the pivoted braces A, asbefore described. The end of the saw is connected to the proper point on the pendulu m and the work of sawing begun, the pendulum acting to steady and carry the free end of the saw, and being guided and steadied in its work by the braces A, between which is formed the way for its travel, as before described. After use, when it is desired to move the machine from one place to another, the saw is detached from the pendulum, thepivotedbraces disengaged from the crossbar A and turned down between the forward pair of uprights, and the parts thus closed together from the lower end, the rear pair of uprights passing astride the forward pair of uprights, the pendulum closing in between the pivoted braees, and thus the whole machine being closed into a very compact form. The saw may then be tied or strapped onto the machine, as indicated by the dotted lines in Fig. 3, when the whole apparatus can be Very easily taken up and carried to the next scene of operation.

WVhile I have shown four uprights composing the frame, it will be readily seen that three or any number might be substituted without departing from my invention.

Having thus fully described my said inven- IOO 2. lhe combination, in a sawing-machine, of two pairs of uprights, A, pivoted together at their tops, the forward pair being arranged parallel with each other and provided with a foot-piece, a, the rear pair being flared apart at their lower end and connected by the crossbar A, the pendulum B, pivoted on the same pivot which secures said uprights together, and the braces c, pivoted to one pair of said uprights and formed to engage with the crossbar A of the other pair, said braces being arranged to form a guide for said pendulum, substantially as set forth.

3. In a sawing-machine, the combination of the uprights A, pivoted together at their top ALFRED W. CARTER.
