OF MIDDLETOWN, CONNECTICUT.

IMPRQVEMENT lN PRINTERS lNKlNG-R OLLERS.

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

I, CHARLES S. WESTCOTT, of Elizabeth, in the countyot' Union and State of New Jersey, have intented-l certain Improvements in Printers Inkiug- Rollers, of which the following is a specification.

My invention has forits chief object the improve ment of the printers ink-roller, now in general use,

composed mainly of glue and treaclc, or of glue and honey, glycerine, or some similar or analogous substance, by covering the same-with a.skin or outer surface of India rubber, gutta-percha, leather, cloth, or other suitable material, so as to give the ink-roller more durability, and rendering it more easily to be cleaned.

' I also design to include within the object of my invention an ink-roller covered as aforesaid, the body of which will be sponge, or combined with ,glue, glyccr rine, or other substances suitable for the body of the roller, excluding, however, India-rubber sponge or India-rubber moss.

To accomplish this, 1- make a sack or skin of India rubber, vulcanized or .not, leather, cloth, or other, suitable fabric, which, when tilled as hereinafter described, will be. of size and form required for the contemplated ink-roller. The inside of this sack or skin I make. rough or corrugated, so as not toslip or turn easily upon its filling. 'lhrough the. sack or skin, longitu-.

dinalty, 1 insert a shaft or spindle for the center of the roller. The ends of the sack or skin Iclose up around the shaft or spindle with India rubber skin,

India-rubbei cloth, leather, cloth, metal plate, or other.

suitable material, to cause it to adhere firmly t0 the shaft or spindle, and prevent slipping or turning upon it, making or leaving a hole or opening at one end through which to till'the skin or sack. I thenplace the sack or skin, with the spindle or shaft in-- serte d iutoa hollow mold of suitable form and smoothness inside, and fill the sack or skin through the open ing with a composition of melted glue and treacle or glue and honey, such as is usually used in the formation of ink-rollers, and of the requisite consistency, or

wit-h other substance of a similar nature, or with finc pulverized sponge, singly or combined with glutinous or other suitable substances, (not India-rubber sponge. or Imlia-rubber moss, which are expressly excluded,)

which will be of the necessary consistency and pliability to form the body of ink-rollers. The opening maythen be closed or not, as desirable. The roller is then ready for use.

' What I claim, and desire to secure by Letters Pat eat, is-

1.- An ink-roller, the body of which is composed of a composition ofglue and treacle or. glue and honey, such as is generally used in the ibrmation of printers ink-rollers, or of some other substance (not rubber or moss) of a similar nature which will be ofth'e consistency and pliability requisite for tbe'body of the roller, in combination with an external surface or a coating of solid rubber, either. vulcanized or not, gutta-percha, or of leather or fibrous or textile material, or combined with rubber, gntta-percha, or some of a )rintei"s ink-roller not includim India-rubber sponge or Iudia-rublmr moss, combined with an outer skin or covering of India rubber, gutta-percha, leather,

cloth, or some other suitable material, substantially as set forth.
