COPYING-ROLLER.

SPECIFICATION forming part of Letters Patent No. 274,549, dated March 27, 1883.

(X0 model.)

To all whom it may concern:

Be it known that I, CHARLESE. BALDWIN, acitizen of the United States ofNorth America, anda resident of the city, county, and State of New York, have invented a new and useful Improvement in Copying-Rollers, of. which the following is a specification.

The object of this invention is to provide a cheap, simple, and convenient device for use "in copying letters, manuscripts, &c.a device that may be successfully substituted for the well-known lettencopying press now in general The invention consists of two rollers held in position apart and parallel to each other by a suitable handle, one of said rollers being composed essentially of a hard inelastic non-absorbent material and the other of an elastic absorbent material. or

Reference is to be had to the accompanying drawings, composing part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figural is a side elevation of the device. Fig. 3 is a plan of the same.

In the drawings, A represents a smooth cylindrical roller, of wood, iron, or other inelastic substance, and B a cylindrical roller consisting preferably of an inelastic portion, B, enveloped by an elastic and absorbent cover, B which may be composed of felt, woven fabric,

sponge, or the like, but may consist entirely of elastic and absorbent substance.

0 represents a doubly forked or branched handle in whose eyes or bearings c a are engaged the axles b 0, respectively, of the said A link, 1), may, if desired, be engagedover the ends of therespective rollers A B, or, rather,

When it is desired to take a copy of a letter 7 the absorbent roller 13' is properly moistened by dipping it in water or rolling it over a wet surface, and then is applied (rolled) by the oporator, who grasps the handle 0, over thesheet on which the copy is to be taken, whereby said sheet is suitably moistened. The letter is then laid face downwardon the moistened sheet, and the inelastic roller A is, with suitable pressure, passed over the back of the letter. Thus a copy may be obtained with much less labor, with greater ease, and as much certainty as with the ordinary expensive and cumbersome letter-copying press. I

A thick piece of felt removably secured in the bottom of a suitable vessel,and kept moistened, is best adapted to supply the proper amount of moisture to the roller B, the latter being rolled over the said moistened felt before being applied for use. When either one of the said rollers is applied in use the device is tilted by the operator, so thatthe other roller shall not come in use. c

Having thus described my lili'6ilfi01l, l claim as new and desire to secure by Letters Patent-- As a new article of manufacture, a copyingroller constructed substantially as herein shown and described, consisting of an elastic and absorbent roller and an inelastic non-absorbent roller, held in position apart from and parallel with each other by a suitable handle, as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 21st day of November, 1882. a
