PHlLIPP SCHNEIDER, OF HAMBURG, GERMANY.

COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 271,525, dated January 30, 1883. Application filed March 13, 1882. (No model.)

To all whom it may concern:

Be it known that I, PHILIP]? SCHNEIDER, of Hamburg, in the Empire of Germany, have invented a new and usefulImprovement in Copying-Presses, of which the following is a specification.

The invention relates to the class of press for copying letters or other writings, &c., which consists of two iron parts or frames with upright sides hinged together, so that the parts or frames may be folded or unfolded, like a book. The two said parts or frames are provided on the side opposite the hinges, one with a stud or roller and the other with a lever having a hooked end or nose, which is adapted to engage with said stud or roller for drawing the parts or frames together and exerting a pressure on a book or papers placed between them.

My invention consists in a novel combination, with the two parts or frames and the lever and stud or roller for drawing them together, ofa spring arranged between the hinge connectingthepartsorframes and oneof said parts or frames, and another spring arranged between said stud or roller and the part or frame which is provided with the stud or roller, whereby said parts or frames are caused to exert a yielding pressure on the book or papers placed between them.

The invention also consists in the combination, with the two parts or. frames of the press, of a compartment or receptacle for wetting papers or sheets arranged in one of said parts or frames, a loose plate covering said com partment or receptacle, and a spring bearing upon said plate and serving to keep the wetting papers or sheets in smooth condition, as more fully hereinafter described.

In the accompanying drawings, Figure 1 represents a plan of a press embodying my invention. Fig. 2 represents a back view of the press. Fig. 3 represents a front view of the press. Fig. 4 represents a section of the press in a closed state, without a copying-book or copying-papers; and Fig. 5 represents a section of the press with a book inclosed.

Similar letters of reference designate correspondingparts in all the figures.

The copying-press consists essentially of the box-shaped upper part, A, and the corresponding lower part, B, hinged together by hinges p on one side, which allow the part A to be raised or unfolded for the purpose of putting the copying-book onto the part B, as shown in Fig. 5, or of removing it from this part. The part or frame A carries a hand-lever, H, fulcrumed to it, and the end of the lever is formed as a hook or nose, by means of which it catches under a stud or roller, 1", connected with the part B. The hinge 1), connecting the parts A B, is attached to the latter part by an intermediate spring, F, placed on the bolts 2' i. In a similar manner the stud or roller r, under which the hook or nose of the lever H catches, is connected with the part B by a spring, F. This arrangement allows of the raising of the top part while the pressure is applied, and se cures a uniform yielding pressure upon the copying book or papers. Fig. 5 shows the part A raised by the pressure exerted on the'book, while Fig. 4 shows both parts close together without the copying-book. The part B of the press is furnished with a compartment or re ceptacle, 1), used for the reception of wetting paper or sheets, which may be kept in a smooth condition between the bottom of said compartment or receptacle and a loose plate, 6, fit ted to the said compartment or receptacle, the

said plate having an elastic pressure applied to it by a spiral spring, 0, applied between it and the top plate, Z, which is secured to the top of the part B. This top plate, Z", and the portion of the part B immediately below it, to which it is secured, are seoured'by hinges q q to the bottom plate of the part B.

The operation of copying is as follows: The lever H is placed in the position shown in Fig. 3, in which position it is kept by a springcatch. The upper part, A, is then fully opened and the copying book or papers put on the lower part, B, ofthe press. The cover or partA is then folded down, as shown in Fig. 2, and the lever H is operated to cause its hooked end or nose to engage with the stud or roller r. The copying-book is thereupon compressed between the parts A and B.

The use of the springs F F is advantageous, because they adapt the press for receiving books of different thicknesses.

That I claim as myinvention, and desire to secure by Letters Patent, is-

1. The combination, with the two box-like parts or frames A B, of the hinge p, the lever TOO box, substantially as and for the purpose herein, fnlcrurned on the side of the part A, the
