PRINTING-MACHINE.

SPECIFIGATIDN forming part of Letters Patent NO. 697,089, dated April 8, 1902.

Application filed May '7, 1900. Serial No. 15,869. (No model.)

To all whom it may concern:

Be it known that I, ERNST JENSEN, a subject of the King of Saxony, residing at Munich, Bavaria, Germany, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification.

In the accompanying drawings illustrative of a machine constructed in accordance with my invention, Figure I is a vertical longitudinal sectional View; Fig.II, an end elevation; Fig. III, a top plan view with part of the handle broken away; Fig. IV, a plan view of the guide-rail on a reduced scale, and Fig. V a transverse sectional view thereof.

Like letters of reference mark the same parts in all of the figures of the drawings.

The machine is provided with a hollow cylinder a, having interior screw-threads in its ends to receive screw-plugs (Z and e, which latter have threaded openings in their outer ends to receive journals g and h. A pin w enters the edge of cylinder at and of a cylinder 1; to prevent them from moving upon each other. The design-roll c is carried by a hollow shell or double cylinder a2, mounted on cylinder Z), the design-roll being a cylinder of felt with or without the design branded or burned in or on its periphery, or of soft gum, celluloid, hard gum, metal, or other suitable material, while the shell 00 is elastic and filled with air and is to be removed or replaced with the designnoll. In the surface of cylinder c is a small semi-annular groove 3 to receive wards on the steel sheet of the guiderail M, Fig. IV.

The design -roll when of celluloid, hard gum, metal, or the like serves for the production of cameo or intaglio designs on soft moist cement, plaster, asphalt, or the like.

The screw-plug c has formed with it a disk e, which serves as the head of said screwplug and holds the design-roll against endwise movement, while a similar disk-head d on the screw-plug d serves the same purpose at the opposite end of the design-roll. The disk (P has formed integral with it a second disk cl, partially separated from it by an annular space or groove of a width and depth conforming to the narrow part a of the guide rail, Fig. V.

The journals g and h are mounted in bearings in a bowf and may be readily and easily placed in or removed therefrom bysimply unscrewing them from the plugs 61 and e.

K indicates the reservoir for ink or color, which is secured to lateral projections from the bow f by means of screws 8 and t, which enter slots in said projections, whereby the distance of the reservoir from the axis of the design-roll may be regulated. (See Figs. I and IL) The reservoir is longitudinally slotted in its bottom to permit of the projection therethrough of an inking-roll m into contact with the design-roll, said roll m being journaled at one end in the head Z of the reservoir and at its opposite end in a disk 0, seated in the opposite end of the reservoir and covered by the cap or head 1), said disk 0 being secured by a pin .2 and provided above the roll with an opening through which to fill the reservoir when the cap or head 19 is-re* moved. The steel sheet a secured upon the guide-rail it, forms the bottom of the groove to and has formed upon its edge wards of, while the part a has openings or notches u When the machine is to be started, it is placed upon the guide rail or disk d in groove to and part a in the annular groove between disks d and d and with pin 1; resting in any one of the notches or openings 10' {of guide-rail u, so that the device will roll on the guide-rail away from or toward the handle thereof, as

desired, one of the wards 1L entering a groove y and the pin 0 entering one of the notches n whereby the design-roll is kept from sliding and held clear of the ink-roll during its movement in its eitherdirection.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a printing-machine, the combination with a hollow cylinder having interiorlythreaded ends, of screw-plugs threaded in said ends, a bow, and journals mounted in bearings therein and threaded into the outer ends of the screw-plugs, substantially as described.

2. In a printing-machine, the combination with a hollow cylinder having interiorlythreaded ends, of screw-plugs threadedin said ends and having threaded openings to receive journals,said screw-plugs being also provided with disk-heads and a design-roll held in place between said heads, substantially as described.

3. In a printing-machine, the combination with a hollow cylinder, of screw-plugs threaded in the ends thereof, journals threaded in said plugs, a bow having bearings for said journals, and projections radially slotted, and screws passing through the reservoir-shell and into the radial slots, substantially as described.

4. In a printingniaehine, the combination with the design-roll and its supports, 00m-
