LETTER-COPYING PRESS.

SPECIFICATION forming part of Letters Patent No. 555,653, dated. March 3, 1896. Application filed December 4,1894. $erialNo. 580,784. (No model.)

To all whom it mag concern:

Be it known that I, EDGAR l3. MILLERT, a citizen of the United States, and a resident of Portland, county of Multnomah, and State of Oregon, have invented certain new and use ful Improvements in Letter-Copying Presses, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts in all the figures.

This invention relates to rollers for copying documents without the aid of a press, and has for its object to provide a simple, cheap, readily-constructed and perfectly-operating device of this character, which will present a solid rigid face to the letter or copying book or pad to insure a speedy impression and at the same time yield or adjust themselves to the irregularities or undulations of the surface of the said book or pad.

The invention consists in the novel construction and arrangement of parts hereinafter fully described.

In the accompanying drawings, Figure 1 is a front elevation of a roller embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an inverted plan view thereof.

In the practice of my invention I construct a yoke A,of metal, comprising arms B at each end and a central enlargement A, to which is rigidly secured a vertically-ranging handle 0, of any suitable shape. In each of the arms B is screwed a pivot B, extending therethrough and into a transverse bar or plate D, apertured in either end thereof. Between these plates are placed two adjacent solid or tubular metallic rollers E, having journals or gudgeons E thereon, which have their bearings in the apertured ends of the bars D and are but loosely journaled therein.

The operation of the device is as follows: The page of the book or pad having been 1n oistened, the letter or other document placed thereon and the oiled paper or card inserted thereunder, as ordinarily, the handle 0 of my device is grasped and the rollers E pressed down upon and rolled over the entire surface of the letter, and as the pressure exerted is vertically downward a hard surface is pre sented to the paper; but when, as necessarily occurs where a plurality of pages of the copying-book have been used, the surface of the book is undulating or irregular, the plates D being pivoted in the arms B, the same will yield vertically at either side of said arms whenever the roller E in the end thereof which yields encounters an obstruction or raising of the surface of the book, the opposite end of the plate being correspondingly depressed, as illustrated by dotted lines in Fig. 2, whereby, when the roller encountering the obstruction naturally exerts great pressure upon such portion, this is equalized by the consequent pressing downward of the opposite roller, and, furthermore, the plates D not working in unison and the rollers being loosely pivoted therein one end of either roller may be elevated without materially affecting the opposite end thereof unless by slightly depressing the same. By this construction it will thus be observed that however irregular the surface of the letter, the book, or the oil-board beneath the page the rollers will adjust themselves to the peculiarities of their contour, and therefore every word of a letter may be clearly copied without exerting extreme pressure thereon.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a device of the class described, the combination of a single prong or yoke having a rearwardly-extending handle, a plate pivoted to the inner face of each extremity of the prong or yoke and adapted to revolve on said pivot, and a plurality of rollers extending through the space between the plates, each provided with trunnions entering perforations in the latter and held by the yoke from removal therefrom, said rollers having independent movements with respect to the yoke, the plates and each other, and adapted to revolve with thesaid plates.

In testimony that I claim the foregoing as my invention I have signed my name; in presence of two witnesses, this 9th day of November, 1894:. v

EDGAR B. MILLERT.
