To all whom it may concern.-

Be it known that we, JOHN A. BROWNING and THOMAS M. ST. JOHN, citizens of the United States, residing in New York city, county and State of New York, have invented certain new and useful Improvements in Copying-Machines, of which the following is a specification.

The object of our invention is to supply a means for the ready production of a number of copies of drawings and written matter by a dry-copying process.

Our invention contemplates making the copies on a continuous strip of paper or on separate sheets of paper, and the machine is designed to be readily adjusted to accomplish these ends.

The construction and operation of the machine will be understood by reference had to the accompanying drawings, forming a part of the specification, in which Figure 1 is a side elevation of our improved copyinganachine adjusted for printing on a strip of paper. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a view of the absorbent-roller-controlling device detached. Fig. 4 is a longitudinal section of the machine adjusted for printing on separate sheets of paper. Fig. 5 is a front elevation of the same, and Fig. 6 shows one end of the clamping device for holding the absorbent covering on its roller.

The two main side frames to and a areconnected together by the tie-rods a a and are secured to the base a At the front ends of these frames is journaled the pressureroller 1), and at their rear ends are provided open bearings for the shaft 0, which carries the roll of paper 0, and against this shaft springs c bear and act as brakes to prevent racing of the roll of paper when it is being printed upon.

On boxes concentric with the axis of the roller Z) are fitted the swinging frames cl cl, which carry the other rollers of the machine, and the plate 6 (said plate being securely fastened to the frames by screws) acts as a brace to bind the frames together and also performs the functions of a knife, over the edge of which the strip of paper may be cutinto sheets after being printed upon, and this edge may be serrated to facilitate this work.

To look the swinging frame in its two 0perative positions, the bolts f f are fitted to rotate in holes in the side frames CL a, their inner cylindrical portions being cut away, as shown in Fig. 2, to allow the curvilinear parts 61 of the frames .rl cl to pass over them while said frames are being shifted, and they act as stops to determine the two positions of the frames by the outer edges of the recesses d and 61 coming in contact with them. These recesses are shaped to receive the bolts ff when they are rotated by their finger-pieces f f to firmly lock the frame. Figs. 5 and 6 show the frames (2 d locked in their upper position.

The paper-receiving roller g has bearings in the frames d d, is provided with a crankhandle 9 and with a paper-gripping device consisting of a rod 9 and end plates g fastened to the ends of the rod and pivoted to the ends of the rollers in such manner as to permit the rod to pass into a longitudinal groove formedin the roller, so as to carry with it the end of the paper and thereby clamp it to the roller.

Between the rollers 12 and g is located the stripping guide-roller h. This roller h we have found essential to cause the paper to leave the absorbent roller freely, for its adhesiveness is such that the paper is liable to become creased when wound on the roller 9 directly from the absorbent roller. The absorbent surface of the impression-roller t' consists of a gelatinous or other material j suitable to absorb the ink of the drawing or writing to be copied, fixed on afabrio backingj, and to enable this absorbent surface to be readily applied to and removed from the cylon the shafts 2' 2' These catches Z Z, when the coveringj j is being applied, are moved over with their ends Z in line with the groove 11. One end of one of the rods is placed under the end of one of the catches, so asto project a little beyond the catch. This end of the fabric and rod are then placed in the groove and slid lengthwise until the other end of the rod passes under the end of the othercatch. The covering j j is now wrapped around the roller '1', said roller being held away from the pressure-roller h during this operation, as hereinafter described, and the other end of the fabric and its rod are inserted in the groove and under the ends of the catches. over, their cam or inclined surfaces acting on the ends of the rods 76 7t to draw the roc s toward the center of the roller, thereby causing the covering to hug the roller closely. To prevent the rods 7c 7; working out endwise, the catches are provided with the flanges Z Z and to assist in inoving the catches over to draw on the rods 76 7c the guide-brackets m m, fastened on the ends of the rollers t, are provided, said pieces being so shaped as to overlap flanges Z Z and thus hold the outer parts of the catches against the ends of the roller 2'. To cause the roller t to bear with a yielding pressure against the pressure-roller Z) and to hold it away when required the following device is employed at each side of the machine. A plate a is held against the frame by a screw a and receives the end of the shaft Said shaft also plays in the slot (1, which has its opening near where the screw n is located, as clearly shown at Fig. 3. The plate at has a curve-shaped slot which works on the screw '17. and which has a re-entrant notch 41 The spring 0 is attached to plate a and the frame and draws the rollert' toward the roller 1). Now to withdraw and hold the roller away from the roller 1) the plates 11 n are moved back until the re-entrant notches n a catch over the screws 11 n, and when it is desired to entirely remove the roller '2'. for the purpose of replacing itby another of a different size the screws n n are taken out and the plates not slipped off the ends of the shafts 1' e which allows the shafts to slide out of the slots d To operate from a roll of paper the machine is set as shown at Figs. 1 and 2, the paper a placed on the shaft 0, around the pressureroller b, the guide-roller 72, and clamped to the roller g, upon which it is wound. The roller 1', with its absorbent surface carrying the device or matter to be printed, bears against the paper as it passes over the roller Z) and imprints it as fast as it can be conveniently wound on the roller g. The paper 0 is shown as passing under the tie-rods a a This is not necessary. IVhen a small roll is used, it can pass directly to the roller 1); but if as large a roll as can be placed in the machine be used then it may be convenient to pass the paper under the rod a After the desired number of impressions have been run off, the paper from the roller g, after being separated from the main roll, is drawn over the knife 0, as shown at 0 and by means of its edge out or torn into sheets. In operating with separate sheets, with the swinging frame and its attendant parts set in The catches are now moved the position shown at Figs. at and 5, a table 1) is used, upon which the sheets are placed to be fed to the machine. This table is provided with hooked brackets 19 p at one end, which set over the projections a or, extendin g upwardly from the front end of the frames to a, said brackets having side lugs 19 13 which rest against the sides of the frames a a to prevent lateral movement of the table thereon. The roller 1' is prepared for this work by placing a strip of paper or other suitable material (1 on the absorbent surface extending over the slot 1" or where the spaces at the top and bottom of the sheets to be printed will come. Gelatinous material, if used, has sufficient adhesiveness, especially if slightly moistened, to hold this paper q in place. In starting, the roller is set with this piece of paper (1 adjacent to roller 1), the end of the first sheet r to be printed is started between the rollers, and the roller i is turned until this end of the sheet is at top, as shown. The end of paper 9 is, by reason of the paperguard q, free and easily grasped by the fingers, which would not be the case if this guard were omitted. The sheet is now pulled, stripped from the roller, and the roller rotated until the guard 1 again comes in position for the end of the next sheet of paper to be fed against it. Then upon continuing the pull on the first sheet until it is clear of the roller the free end of the next sheet is in position to be grasped by the hand, which is pulled off the roller, as was the first sheet, and another sheet fed, as before, and so on, the work being accomplished as quickly as the sheets can be fed to the roller and pulled off.

The table 19 is of a width to lie in the bottom of the machine between the frame a a when not in use, and is so shown in Figs. 1 and 2.
