To a, whom it may concern.-

Be it known that I, CHARLES ELLSWORTH ADAMSON, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Rotary Copying-Press, of which the following is a s ecification.

My invention re ates to improvements in rotary copying-presses or machines that are used for making press-copies of business-letters and all written documents; and the ob j ects of my invention are to construct a simple and durable machine in which the copying-paper is carried in a roll and cut ofi into loose sheets before the copy is made, thereby making the copies on loose sheets, the paper being cut of a length to suit each particular letter.

A further object is to arrange the machine so the copy is made in full view of the operator and also to arrange the mechanism so that a letter can be given one or more impressions before removing the co y from it.

These and other objects I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my machine, showing it as it appears when making a copy. Fig. 2 is a longitudinal section. Fig. 3 is a front end elevation, and Figs. 4, 5, 6, 7, and 8 are detail views.

Similar letters refer to similar parts throughout the several views. Q

The main frame of my machine consists of two side rails A A, which are made right and left, and the front cross-end C and rear end 0. The ends 0 and C firmly hold the sides together by means of machine-screws a, all as shown in Figs. 1, 2, and 3. At the forward end of the frame are two elevated bearinglugs A A, which form j ournal bearings for the journal ends of the rubber copying-roller B. One of the journals of the sald roller extends througha lug A, so that the crank B is secured. Directly below and parallel to the co ying-roller B is a small metal bearingrol ler D, journaled on the frame. (Most clearly shown in Figs. 2 and 3.) This roller is set a proper distance from the rubber roller, so as to give a suitable im ression or pressure to the copying-plate E, w 'ch works between them. The sand plate E is made of thin metal, having two of its edges 6 I) turned down to stiffen it. The rear end a of the said plate is beveled off, forming a cutting edge for cutting the copying-paper crosswise into sheets. Two guide ears or projections d d are formed on the rear corners of the plate. (Most clearly shown in Fig. 4.) These projections fit into a groove 6, cut into the inside of each side rail A. (Most clearly shown in Figs. 1, 6, and 7.) By these projections resting in the said grooves the copying-plate is supported at its rear end, allowing the said plate to move freely endwise, as is the case when making a copy, and they also form a stop for the plate to prevent it from running entirely out of the rolls B and D. The grooves e extend from a point of contact between the rolls B and D to a point near the rear end of the side rails, all as shown in Figs. 1, 2, and 7.

In Fig. 2 the plate is shown run back as far as it will go, showing that the forward end of the said plate is still resting between the said rolls B and D. and that the rear or cutting end of the plate is resting against the copyingpaper and roller K.

On the inside and near the lower edge of each of the side rails A A is a rib F, which extends almost the entire length of the said rails. (Most clearly shown in Figs. 2 and 6.) On each of these ribs rests an impression-bar G, one of which is shown in Fig. 5. These bars are each formed with two j ournal-bearings f and g and a bearing-recess h for the ends of the impression-spring H, all as clearly shown in Fig. 5. The impressionspring H extends crosswise of the frame, each end resting in a recess h and on the rib F. In each central bearing f rests one end of the journal I for carrying the roll of copying-paper, the position of which is indicated in Fig. 2. In the end bearings g the journals of the moistening-roller J are secured. (Most clearly shown in Figs. 1 and 2.) The said moistening-roller is made of tubing having a cast head J secured in each end, the outer end of each head being formed into a spindle or journal J. (Most clearly shown in Fig. 8.) This roller is covered by having a thin linen cloth J wound around it and the cloth turned in at the ends of the roller into a recess formed by the heads J, being set in a short distance back from the end of the roll, and after the cloth is turned into the recess it is securely held in place by a spring-ring i. (Most clearly shown in Fig. 8.) The moistening-roller J rests directly against the paper-delivery roller K, which is journaled to the side rails AA just in rear of the moistening-roller, and it being muchsmaller than IIO the latter and journaled higher up on the frame it inclines to hold. the moisteningroller down, bearing the bars G against the ribs F. The delivery-roller K is madethe,

, is also covered with cloth in the same manwater-pan ner as roller J. The pressure of roller J against roller K is regulated by a thumbscrew L, which is adjusted to bear against the spring H, the said screw being tapped into the end bar C near its central part, all as shown in Figs. 1, 2, and 3. The roll of copying-paper is supported in the journal I, which rests in bearings f f on the bar G, and the paper from this roll passes down under roller J and up between it and roller K, and by the adjustment of the impression-screw L the said paper can be moistened to any degree desired. It will be seen in Fig. 2 that the dampening-roller J extends down into the M, which surrounds the lower por tion of said roller, and by keeping this pan sufficiently full of water to reach the roller the cloth covering will absorb and retain the moisture at all times and dampen the copying-paper as it runs around it. ,Just in rear of the roller K is pivoted a small threadguide roller N. (Most clearly shown in Figs. 1, 2, and 7.) This small roller N is parallel to the roller K, and a number of heavy threads K encircle the two rolls K and N. (Most clearly shown in Figs. 1, 2, and 7.) These threads are for the purpose of separating the moist copying-paper O fromthe impression-roller K at a point where the cutting end 0 of the plate E comes in contact with the said paper and roller K. The threads are placed about one inch apart, and they are held in their positions by the copying-paper adhering to them and to the roller K. (Most clearly shown in Figs. 1 and 2.)

By locating the roll of copying-paper par allel to the dampening-roller and on bars G G the paper will feed around the dampening roller freely, and in so doing it passes through the water and against the wet covering on the rollers, and the excess water is pressed out of the paper at the pressure-point between the two rolls. It will be seen in Fig. 2 that the end bars C and C are provided with suitable lugs a, through which the machine-screws a pass to rigidly hold the frame of the machine together.

The operation of my machine is as follows: The letter to be copied is placed on the co ying-plate written side up. The crank I is then turned to the right and a moist sheet 0 of copying-paper is run out, as indicated by the arrows and dotted line in Fig. 2. As soon as a sufficient amount of paper is turned out to cover the written part of the letter it is stretched backward against the cutting end c of the plate E. Then by pulling quickly to one side the sheet Q is cut off. This loose sheet Q, is then laid down over the letter I, and by turning the large crank B to the right the copy-plate E is carried under the copyingroller B, as indicated in Fig. 1. The said crank is turned to the right until the plate is run as far out as it will go, the projections d 61 coming in contact with the end of the grooves e 6 directly under the roller B. Then by reversing the crank to the left the plate is run back to its normal position, thus giving the letter two impressions, completing the copy, and resting the plate in the position shown in Fig. 2. This operation can be repeated according to the number of letters to copy, or if two or more copies are desired from the same letter the first copy is removed without disturbing the letter and the copying operation repeated for each copy desired.

When it is desired to copy a sheet written on both sides, a sheet of moist copying-paper is. cut off and placed on the plate, then the letter placed over it, and another sheet of moist copying-paper placed over the letter, so that the letter is between two moist sheets, in which position it is given the copying impressions. Two or more letters may be copied at one time by placing them on the copying-plate one over the other, with a sheet of moist copying-paper in contact with the written side of each letter. This, however, is limited, as the more sheets placed on the copying-plate the harder the impression and the more power it will require to operate the copying-roller.

I do not confine myself to any particular way of fastening the cranks B and K or to other minor details of construction.

I do not desire to claim herein the copying device, as that has been made the subjectmatter for a separate application which was filed February 10, 1905, and bears Serial No. 245,119.
