Letters Patent No. 99,395, dated Februa/ry 1, 1870.

aIIMPROVEIVIENT IN PRINTING-PRESSES.

The Schedule referred to in these Letters Patent and making part of the same.

Zo all vwhom it may concern:

Be it known that I, THOMAS W. BRACHER, of the city, county, and State of New York, have invented a new and useful Improvement in Printing-Machines; and I- do hereby declare that the following isa full, clear; and exact description of the same, which will enable others skilled in the art to make and use the same, reference being'had to theaccompanying drawings, forming part of this specification.

The present invent-ion more particularly relates to a machine adapted and intended for the printing of tips for hats and caps, although the improvements embraced herein may he applied to machines for printing other surfaces or articles; and, in such machines, the invention relates to the manner of inking the type thereof. y

The invention consists in a carriage,wh'ich carries, at one end, the hiking-roller and a spring-pawl, its other end being formed with a handle.

Said carriage is arranged, in relation -to a toothed rotating cushion, the form, anda stop, so as to oper ate, in a manner as will be hereinafter more fully described.

In the accompanying plate of drawings, my improvements in printing-machines are illustrated- Figure 1 being a plan `or top view of a sufficient portion of a machine for printing hat and cap-tips to show my improvements;

Figure 2, a central longitudinal vertical section, taken on the plane of the line :v as, tig. l; and

Figure 3, a transverse vertical section, taken on the plane of the line y y, tig. l.

` Similar letters of reference indicate corresponding parts.

A A, in the drawings, represent two uprights or posts, placed in positions parallel to each other. These posts,in a complete and perfect machinefor printing, formvthe guides for the head or holder B (carrying the type or impression-plate C) to move in, when, by and through a lever, or other suitable means, such head B is operated in a downward and upward. direction, to produce a print or impression, from its type or plate, upon paper or any other suitable surface or material which may have been previously placed upon a carriage or bed-frame, D.

The carriage D is arranged to move-on parallel ways or guides, E, fixed in position upon the' crossbar F, connecting the two posts' A, and, in its movement, passes between such posts.

G, a handle, applied to front end of carriage, for convenience in operating it.

H, two parallel extension-arms, fixed to rear end of carriage D. y

To these arms H, at their outer ends I, by thumb or set-screws, are secured slotted uprights' or standartis, K, which, in and between their upper ends L, i carry a roller, M, that, in construction, is tov be similar to any ot' the rollers in printing-machines em` ployed for the iukiug of the type or other impressionsurface.

The carriage D, at its rear end, and between the arms H, is out or hollowed out, as shown in iig. 1

such a manner that the inking-surface of the cushion will be horizontal, or nearly so, and in a plane corresponding, or nearly so, to the movement of the bedframe carrying the ink-roller.

R, a series of ratchet-teeth, formed around the cushion N, at equal and regular distances apart.

With these ratchet-teeth R, a spring-pawl, S, of the carriage D, engages, as such carriage is moved forward, turning the cushio around to a greater or lesser'extent, according as the two parts may. he relaf tively arranged.

T, a stop, ixed to frame of machine, for regulating and limiting the forward movement of the carriage.

The paper or other surface to be printed is first laid upon the carriage in proper position. The carriage is then moved sufficiently forward to bring the typeholder or head down upon the paper carried by it, and

thus the impression of its type is left thereon. Now, draw back the carriage, and remove the said printed sheet, substitute another for it, and again move the carriage forward under the type-holder, and bring such type-holder down upon it, and so on.

Each time .the carriage is moved forward, the inkroller carried by it passes over the ink-cushion, from which it is supplied with ink, such cushion, at the -same time, being partially revolved. And eachtime the carriage is moved backward, its ink-roller passes under the type-head, to the type of which it imparts the ink necessary to give the requisite impression.

I claim as new, and desire to secure by Letters Patent- The carriage D, carrying the roller M and spring- .pawl S at one end, and formed with a handle, G, at

the other end, in combination with the toothed rotating cushion N, form C, and stop T, the parts being constructed and operating together as herein described.
