IMPROVEMENT IN PRINTERS INK-ROLLERS.

Specification forming part of Letters Patent N0. 38,1 13, dated April 7, 1863.

To all whom it may concern:

Be it known that I, GEORGE LITTLETON, of Cleveland, in the county of Guyahoga and State of Ohio, have invented a new and Improved Mode of Constructing Inking-Rollers for Printers Use; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure 1 is a perspective view. Fig. 2 is alongitudinal section. Fig. 3 is a transverse section.

The nature of my invention consistsin constructing a roller in two parts, with bearers of woolen, rubber, or other elastic substance, and a set-screw for the purpose of adjusting the surface when required, each end of the roller having a flange, upon which is fastened a prepared rubber covering, and by these means I make a very durable roller, good in any temperature, and easily repaired by putting on another covering when one is worn out.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I make roller A of wood or other suitable material, having a flange, B, on one end, a portion of the other end being turned about two-thirds smaller than the main roller. There is a collar-piece, O, fitted loosely on this smaller part, which also has a flange, D, and is provided with a screw and nut, E, passing through it lengthwise for the purpose of tightening the surface when necessary. It also has apin, f, secured to it, which plays in a corresponding hole in the main roller to keep the collar 0 from turning and twisting the surface out of shape. There is a counterbalance, g, placed in the main roller opposite the screw E to equalize the weight. There are bearers II H H H, of woolen, rubber, or other elastic substance, placed at intervals around the main roller A and collar 0. Over these bearers are stretched wires or strings I I, the ends of which are fastened to the flanges B and 1). They are for the purpose of preserving the rotnndity of the surface. Over these wires or strings is placed a covering of several thicknesses of woolen cloth or other elastic substances, K, forming a cushion and giving elasticity to the surface, and over all I place a covering of prepared-rubber cloth, L, which, together with the woolen or elastic covering, is fastened to the flanges B and This rubber surface I prepare by passing a heated iron over it and burning it sufliciently to produce a sticky surface, which holds ink and imparts it to type precisely as the ordinary compost tion-roller does.

By this means I produceatype-inking roller thatis equal to the best composition-roller, and it is a durable one, working equally well in all temperatures, and is very readily repaired by simply removing the old and replacing it by a new outside covering.

. What I claim as my invention, and desire to secure by Letters Patent, is

The construction and arrangement of the roller A and collar 0. with the flanges B and D, the screw and nut E, pin f, counterbalance g, bearers H H H H, wires I1, cushions K, and the prepared-rubber surface L, in the manner herein described, and for the purpose set forth.

GEORGE LITTLETON.
