Letters Patent No. 99,131, dated January 25, 1870.

IMPROVEMENT IN SAWING-MACHINES.

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

To all whom it Imay concern:

Be it known that we, LOUIS BACH and L. C. CHRST- LIP, of Tlfn, in the county of Seneca, and in the State of Ohio, have invented certain new and useful Improvements in sawing-Machines; and do hereby declare that the following is a full, clear, and exact de- Letter A represents the two main uprights which' form the frame, and which are supported and braced by the props B. v

Pivoted to a cross-piece, C, extending between the props B, is the treadle D, which is connected by the rod E to the crank-shaft F.

This shaft has its bearings upon the front side of the beams A, and is provided with a large drivingwheel, G, and has a crank formed in its centre, so as to be operated by the treadle D and a handle, H, attached to its end.

Secured to the under side of the beams, but lower down, there is a second shaft, I, which has a small cog-wheel, K, att-ached to it, which gears in the larger one, G.

Fastened to the end of this shaft there is an eccentric, L, to which thelarm M is' attached.

Rising .upward from the prop B is the support or standard N, which is braced and strengthened by the arm O.

Upon the top of the standard N there is pivoted a sleeve, P, through which the arm M is Iliade to pass, so as to serve as a guide while holding it up.

Pvoted to the outer end of the arm M is the pitman R, which operates the saw.

Extending perpendicularly between the prop B and the beam A is the guide S, which consists of two metal plates, between which the pitman plays.

In the side of the cross-piece T, between the two beams A, there is a number of curved metal prongs, which serve to hold the stick of wood while being sawed.

After the saw has made one cut, and the wood has to be moved forward for a second, the saw is raised upward by pulling on the cord V, which passes up over the top of the cross-piece W, which joins the two beams together, and is then fastened to a hook, which holds the saw suspended while the wood is being moved forward.

This. cord is attached to a slide, Y, which plays up I and down between the guides S. When the cord is drawn downward, this slide is pu'lled upward, which presses against the pitman R, and raises the saw from the wood. p

This machine can be operatedA either by hand, foot,

lor any other motive-power, and forms one of the cheapest, simplest, and most effective machines yet invented. It is so light that it can be readily moved `from place to place, and is simple in its operation and construction.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, is

1. The standard N, provided with the movable sleeve P, when used to guide and support the :arm M, substantially as set forth and described.

2. llhe arrangement ofthe guides S, between which the bar R moves, standard N, sleeve P, pitman M, and arm R, with thel slide Y and cord V, all substantially as and for the purposes herein set forth.

In testimony that we claitn the foregoing, we have hereunto set our hands, this 17 t-h day of May, 1869.

` LOUIS BACH.

L. C. CHRISTLIP.
