PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 351,265, dated October 19, 1886.

(No model.)

T0 to whom it may concern:

Be it known that I, J .urns TAYLOR HOYT, a citizen of the United States, residing at New York, in the county and State of York, have invented new and useful Improvements in Printing-Machines, of which the following is a specification.

This invention relates to machinery for feeding and printing sheets of paper, containing a yielding bed supporting a pile or package of sheets of paper, so that the outer end of the pile is constantly pressed against a printing and delivery roller, which has at or near its ends a frictional surface, by means of which the top sheet is removed from the pile during the revolution of the roller, the roller being provided with a printing or impression surface arranged between the frictional surfaces, so that the sheet or a portion of the sheet is printed during the same revolution.

The various devices and combinations eonstituting the invention are described in the following specification, reference being had to the accompanying drawings, in which Figure l. is a longitudinal section on theline .r .r, Fig. 2. Fig. 2 is a front elevation of the machine. Fig. 3 is a vertical section on the lineyy, Fig. 2. Figs. 4 and 5 are detailed views of parts which will be hereinafter described.

Similar letters indicate corresponding parts.

The letter A designates a platform which supports the operative parts of the machine.

B is a bed that supports the pile of paper. The rear end of the bed is connected to the rear end of the platform by a hook or hinge, O, the forward end of the bed being left free, so that the bed can move vertically on the hinge. Under the forward end of the bed are placed springs D D, which rest upon the platform, and which press the bed with the pile ofpaper upon it constantly upward against the printing and delivering roller.

The letter E designates the paper, consisting of a number of sheets placed one upon another in a pile or package, in which position they are held together by means of an awl or blade, F, which is passed through the rear edge of the sheets at about the center of the width of the sheets. The awl F extends up from a plate, G, which is arranged under the paper, as shown in Fig. 1, and which has upon its under surface a hook, H, by means of which the pile or package of paper is connected to the bed. The awl F and plate G are rigidly connected to each other, or they may be cut and struck up from a single piece of metal. The awl may be round, but I prefer that it be thin andflat and be arranged edgewise in line with the length of the sheets of paper.

On the rear end of the bed are arranged sockets I, which in this example are formed in a plate, J, that is secured to the bed, the object being to provide means for fastening the pile or package of paper to the bed in such a manneras to allow the paper to be properly presented to the printing and delivering roller, different lengths or sizes of papers being secured to the bed at different points by arranging the soekctsI at different dis tances from the rear end of the bed, so that the hook H, on the bottom of the package of paper, can be inserted in one or another of the sockets I, so as to bring the free outer ends of the packages at the proper place under the printing and delivering roller.

It is obvious that the socket-plate J can be made adjustable on the bed, if desired, so as to accommodate the device to various lengths or sizes of paper.

Over the front end of the yielding bed B is a roller or cylinder, K, mounted loosely on a shaft, L, which has its hearings in upright standards M M, rising from the platform. One end of the shaft is provided with a driving-pulley, N, which causes the roller K to turn in the direction of the arrow shown in Fig. 1, its revolution being caused by means of a ratchet-whecl, O, fast on the shaft, and a pawl, P, which is attached to the roller, and which is held against the ratchetwheel by a spring, Q. \Vhen the shaft is turned the other way, the pawl rides over the ratchet-wheel and the shaft turns freely in the roller without causing a reverse movement of the roller. The length of the roller is about equal to the width of the yielding bed. A portion of the roller at each end is provided with an elastic frictional surface for acting upon the top sheet of the package of paper, and drawing it away and tearing it away from the awl. This frictional surface in this example consists of rings of corrugated'indiarubber, SS, mounted upon the roller in proper positions, so as to leave a space, T, between them for the printing-surface, which consists in this example of an elastic plate, U, of india-rubber, secured to the roller in the intermediate space, T, said plate U being provided on its exterior surface with raised letters, words, and characters, as desired, which are to be printed upon the paper. Care must be taken that the printing-surface of the plate U shall not project from the roller so far as to interfere'with the proper action of the frictional surfaces S,but the characters and types thereof must project sufficiently to reach the paper and make a clearimpression thereon.

The printing-surface U is inked by means of inking-rollers R, which are supplied with ink by any suitable device usually employed for similar purposes. The inking-rollers are free to turn by reason of frictional contact with the printingsurface U. The ends of their shafts rest in bearings in plates V V,

'which are adjustably supported on the standards M, and they are held down to their bearings by means of springs W W. The inking portions of the rollers R do not extend beyond the width of the intermediate space, T, so that the rubber rings S S do not become soiled therefrom.

The operation of the machine is as follows: A pile or package of paper in sheets having been secured to theyielding bed B, so that the .free outer ends of the sheets are directly under the roller K, the bed B and the paper thereon being pressed upward by the spring D against the roller K, when the latter is turned in the direction of the arrow, Fig. 1, the frictional surfaces S will act upon the top sheet of the package of paper to tear it oft from the awl F, and draw it off from the package, the printing-surface U, which becomes inked from the inking-rollers, meanwhile making its im-- The bed 13 should be properly guided, so,

as not to turn on its hinge in lateral directions.

The printing-surface U may be formed of any suitable material, and it may comprise ordinary type, if desired. 7

WVhat I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the yielding bed B, of the awl F, the inking-rollers R, and the roller K, having frictional surfaces S and the printing-surface U, substantially as shown and described.

2. The yielding bed B, secured at its rear end by a hinge or hook to a platform, A, and provided with sockets I, one or more, the hook H, and awl F in the package of paper E, in combination with the roller K, having frictional surfaces S and the printing-surface U, substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in thepresenee of two subscribing witnesses.
