SPECIFICATION vforming part of Letters Patent Nd. 272,388, dated February 13, 1883.
l Application inea August, v14, 1882. (No model.)
To-all whom it may concern: Be it known that I, JOHN M. ROSS, of Bath, inthe county of Steuben and State of'New York, have invented certain new and useful Improvements in Metal Shears or Gutters; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in critters or shears for iron; and it consists in the combination of a suitable frame, a cam which moves a gate having one of the knives connected thereto, a friction-wheel, and a reversible lever and ratchet, whereby the cam is made to 4operate the cutters, as will be more tully described hereinafter.
Figure l is a side elevation of my invention complete. Fig. 2 is an edge view ofthe same.
A represents a suitable base or standard, to which the posts B are secured in any suitable manner. The upper ends of thesevposts are secured together by means of a steel rod or bolt, which passes through them, and which forms a journal or pivot for the friction-roller C to turn upon. This friction-roller has formed upon it a ratchet, D, in which the inner end of the spring-actuated dog G is made to catch. The inner end ot' this dog passes through a suitable guiding-frame, H, and it is provided with a stop, I, to prevent it from becoming detached. The operating-lever P is bent so that it can be swungaround to either side, and thus made to operate the cam in dit'terent directions. The teeth of the ratchet are so formed that the inner end of the dog will operate equally well in either direction.
Moving vertically between the two posts B, and secured to the cam by a steel pin, is the gate K, to the lower end of which is secured the cutter J'. This cutter is made removable from the gate in any suitable manner, so that when injured it can be readily removed and replaced by another. J ournaled in the upper end of this gate, upon a steel pin or block, is the cam L, which has its upper edge to bear against the under side of the friction-roller by means of which the cam is operated. Passed over one of thev posts'is a suitable loop or presence of two Witnesses. Y

frame, N, which can be secured in any suitable position by means ot' a set-screw, 0, and which frame has a friction-roller, R, secured to its inner end. This friction-roller R catches against the under side of the flange formed on `the side ot' the cam, and serves to hold the cam up against the friction-roller, so that the slightest movement of the roller will cause the cam to move at the same time. In between the lower ends of the two posts is secured the second one, Q, of the knives or cutters, and which knife Q is made removable,so that it can be removed and replaced at any time.- When the cam, which is made more bulging upon one side than the other, is moved in one direction,itis specially intended to cut heavy rods and bolts or heavy plates of metal, While when turned in the opposite direction it is specially adapted for cutting light material.
Upon the frontot' the base A are formed suitable standards, in the upper end of which is placed a suitable cam for locking the iron in place while it is being cut. The steel pin, which passes through the cam L into the gate K, is set. eccentrically to the center of the cam. This'cam being held upragainst the frictionroller O by-the'wheel R, the gate is moved vertically by the pin as the cam is made to revolve by the dog G and lever P. By setting this pin nearer to or farther from the center of the cam a greater or less movement can be given to the gate, according to the thickness of the iron to be cut. A
Having thus described my invention, I claim- 1. The combination of a suitable supporting-frame, a friction-roller, ratchet, dog, and operating-lever, with a cam, sliding gate, and the cutters, the parts being combined and arranged to operate substantially as shown.
2. In a metallic shears or cutter, the combination of the friction-roller, the cam, the supporting wheel or roller It, gate, and a mechanism for turning the cam, substantially as described.
In testimony whereof I ailx my signature inv JOHN Witnesses:
