Leners Patent No. 112,794, dated March 21, 1871.

IMPROVEMENT IN SAWlNG-MACHINES.

The Schedule referred to ln these Letters Patent and making part of the same.

To all whom it may concern:

Be it known niet i, JACOB Famos, of Fairmount,-

in the county of Grant aud- State of Indiana, have invented a new and improved sawing-Machine; and I do hereby declare that the following is a full, clear,

and exact description thereof, which will enable others 'x x, tig.`2, being the section line.

Similar letters of reference indicate corresponding parts. v o

My invention relates to drag-saws, and consists in ,an improved mode of balancing the blade, as hereinafter described and subsequently claimed.

A in the drawing represents 'the supporting-frame or bed of my improved sawing-machine.

B is the driving-shaft,A hung horizontally in the rear part ot' the same.

The shaft is rotated by suitable mechanism, and carries a ily-wheel, a, which is, by a crank-pin, l1, connected with the rod C, for operating the reciprocating saw-slide D.

The saw-blade E, which is of suitable form and construction, is rigidly secured to a sliding frame, D, which is, by means of the rod O, connected with .the shaft B.

The frame D is supported on rails, c c, which are, by suitable ears, secured to a beam, E.

This beam is, at its rear end, by a pin, d, pivoted tothe frame A, while its front end carries claws, eV 0- that straddle an arched guide-post, f, projecting from the bed A.

A weight, g, sliding along a vertical post, h, of the frame A, rests on the saw-blade during the operation, and feeds the same into the timber to be cut.

This weight is, to a certain degree, balanced by a pivoted beam, G, which is hollowed to receiveadjustable-weights, and' connected by a rope, i, passing over a roller, j, with the beam F. v

H is a lever, pivoted to a post, k, and provided with downwardly-projecting arm, l, by means of which it can be used to elevate the beam Fand carry the saw up clear of the wood.

The post h has a notched plate, m, with which an ear, n, of the lever E. is in constant contact to lock the saw when elevated. o

I I are other levers, used for holding the log iu place. l i

They are'pivoted or in suitable manner applied to the frame-work. v

The post his pivoted at its lower end, so that it can be swung out of the way together with its weight, g, when the same may not be required.

A log frame, J', having rollers, o, for the log to be moved on, is attached to the frame A, as shown in glEIaving thus described my invention,

I claim as new, and desire to secure by Letters Patent- The hollow pivoted beam G, rope i, and roller j, combined, as described, with beam F, for the purpose specified.
