LETTER-PRESS COPYING-CLOTH.

SPECIFICATIQN forming part of Letters Patent No. 506,610, dated October 10, 1893.

, Application tiled January 7,1893. Serial No. 457,688. (Specimens.)

.To all whom t may concern:

Beit known that l, ROBERT SPURGIN, a citizen of the United States, residing at Chicago, in t-he county of Cook and State of Illinois, have invented a new and useful Improvement in Letter-Press Copying-Cloths, which I desire to protect by Letters Patent, and of which the following is a specication.

The object of my invention is to obviate the difficulty experienced with the cotton copying-cloths heretofore most commonly used in the fact of their edges raveling or fraying after ashort service; thus renderingthem unsightly and troublesome, and, for these and other reasons, often soon unfit for further use.

My improvement consists of a rubber border applied to arectangular piece of suitable cotton fabric, which border not only prevents the fraying of the cloth but also its tearing, except by special effort. Copying-cloths provided with a rubber border, as stated, may be thoroughly and constantly saturated with water without impairing the rubber or aecting its tenacity to the fabric, and they may also be wrung or treated in any way usual with ordinary copying cloths, leaving the rubber border and fabric intact. Unlike the ordinary copying-cloths, Whose edges are raw and unprotected, my improved cloth will even withstand violent strains on, and direct efforts to tear, those parts, to which an ordinary cloth would'often readily yield.

Myimproved copying-cloth is intended to be used in the same manner and for the same purposes as ordinary copying-cloths.

The figure represents a letter-press copying-cloth ten by thirteen inches reduced to one-fourth of that size.

a, a., a, a., indicate a rubber border as described.

made for securing a straight inner edge to the border, which is essential to the utility, linish and hence the commercial value of the improvement. Both the inside and outside edges of the border are capable of being trimmed straight and to a uniform width on all sides of the cloth, after the process above referred to.

The construction as described may be modifled by omitting the rubber border from either or both of the longer sides, particularly when such side or sides of the fabric have a selvage. In every case, however, a rubber border would be embedded into the upper and lower edges of the cloth, which in no event would have a selvage.

Having thus described my invention, what I claim,and desire to protect by Letters Patent iscotton letter-press copying-cloth having a uniform border of soft, vulcanized rubber embedded into the texture of the fabric, all substantially as described and set forth.

ROBERT SPURGIN.
