MACHINE FOR CLEANING PRINTERS ROLLERS.

SPECIFICATION forming part of Letters Patent No. '7 53,958, dated. March 8, 1904.

Application filed Tune 25, 1903.

To aZZ whom it may concern.-

Be it known that I, SAMUEL CRUMP,a citizen of the United States, and a resident of Poughkeepsie, in the county of Dutc'hess and State of New York, have invented new and useful Improvements in Machines for Cleaning Printers moved. Machines of this general character are shown and described in Letters Patent No. 678,484, July 16, 1901, granted to F. Hart, assignor, &c., and No. 696,134, granted to me March 25, 1902. In Patent No. 678,484 a machine is disclosed which is more especially designed for cleaning the rollers of typographic presses and in which the printers roller is moved over the cleaning or massage rollers. In Patent No. 696,134 a machine is disclosed which is more especially designed for cleaning the rollers of lithographic presses and in which the cleaning or massage rollers are moved over the printers roller. In the machine of Patent No. 696,134 adisk-shaped cleaner is provided among other instrumentalities for operating upon the roller. The present invention relates to this disk-shaped cleaner, and has for its object to improve the construction of the same with a View of improving its action upon the printers roller in to the left and showing the grainer-disk.

Serial No. 163,079. (No model.)

Fig. 4 is a fragmentary sectional elevation of the grainer-disk on an enlarged scale. Fig. 5 is a face view of the grainerdisk. Figs. 6, 7 and 8 are face views of the blade-disk, showing different arrangements of the blades thereon. Fig. 9 is a vertical section of a bladedisk provided with blades having serrated edges for graining the leather.

Like letters of reference refer to like parts in the several figures.

A represents the traveling carriage mounted on horizontal guide-bars a, and B represents the printers roller to be cleaned or washed. C and D represent two disk-shaped rotary cleaners which are mounted on said carriage to operate upon the roller-either simultaneously or one at a time, as may be most suitable. The cleaner-disk C is provided in its flat working face with blades 0, which operate upon the roller with their projecting edges and remove the liquid solvent, color, ink, and other matter from the roller. The cleanerdisk D is provided, in its flat working face with needles or pins d, which operate upon the roller with their ends and grain the same, producing a soft, napped, or chamoislike surface on the leather cover of the roller. The blade-disk C is secured to the lower end of a shaft-e, which is provided at its upper end with a bevel-wheel e, meshing with a bevel-wheel f on a horizontal driving-shaft F, along which the carriage A slides. The upper portion of the shaft 6 is journaled in a bearing 9 on the carriage A, in which bearing the bevel-wheel is also journaled. The shaft and bevel-wheel are connected by a sliding driving connection, such as a groove and feather, so that the shaft canbe raised and lowered in the bevel-wheel. The blade-disk is raised and loweredby a lever G, which is pivoted to the carriage in rear of the shaft 6 .and pivotally connected to a collar g on the latter.

9 represents a standard arranged on the front portion of the carriage adjacent to the lever for supporting the latter in its elevated position by means of a stud g on the lever entering one of a series of holes g in the standard. These parts are yieldingly held in engagement bya spring g, which is secured to the carriage and bears against the side of the lever.

The blades of the disk C may be arranged in various ways. They are preferably arranged tangentially, as shown in Fig. 6, but may be arranged parallel, as shown in Fig. 7 or in groups, as shown in Fig. 8, or otherwise.

In rotating with the disk each blade strikes the roller alternately in opposite directions and removes the adhering matter therefrom with great thoroughness. The blades throw the removed matter by centrifugal force clear of the roller and the latteris in this manner very effectually cleaned of the liquid solvent, color, ink, and other matters, while the blades keep themselves free from accumulations of removed matter, and are therefore always in good working condition.

The grainer-disk D is mounted and driven like the cleaner-disk C, so that it can be raised or lowered. it represents the shaft of the grainer-disk, h the bevel-wheel at the upper end of said shaft, and 71 the bearing in which the shaft 7b is slidably journaled.

f is the driving bevel-wheel on the shaft F, meshing with the wheel 71..

K represents the lifting-lever of the grainerdisk; l?, the collar on the shaft h, to which this lever is connected; in, the supporting-standard, and k the spring bearing against the lever.

The needles or pins (Z of the grainer-disk are straight and arranged parallel with the shaft of this disk. These needles are secured to the disk by soldering or otherwise and are -movable relatively to each other, so that by drawing the needles through the perforations of the stripper-plate any material adhering to the needles is stripped therefrom.. For this purpose the stripper-plate is provided on its back or upper side with two parallel guide bars or posts Z, which extend through openings in the grainer-disk and are provided above the latter with spiral springs Z, by

which the stripper-plate is yieldingly held against the lower or face side of the grainerdisk. Above these posts there is arranged a collar m, which is mounted loosely on the shaft of the grainer-disk and which moves up and down with the latter. The hub of this collar is preferably provided with a rotary washer m, and a short distance above this hub and washer there is arranged a stopbearing a, through which the shaft of the grainer-disk passes and which is secured to the carriage.

When the grainer-disk is in its lower or working position, (shown in Fig. 3,) the collar m rests loosely on the posts Z and the springs l hold the stripper-plate against the disk, so that the ends of the needles project beyond this plate.

. WVhen it is desired to clean the needles, the grainer-disk is raised by the lever K sufficiently to draw the needles through the perforations of the plate, as represented in Fig. 4:. During this upward movement of the grainer-disk the upward movement of the collar m and washer m is arrested by the washer striking against the stop-bearing n. This ar rests in turn-the upward movement of the stripperplate, the posts Zof which bear against the washer. The further upward movement of the grainer-disk draws the needles through the perforations in the stripper-plate until the ends of the needles are entirely drawn into the plate, whereby all adhering matter is stripped from the needles. The washer m relieves the friction when the collar is raised against the stop-bearing. The springs on the posts l are compressed during this final portion of the upward movement of the grainerdisk. Upon lowering the lifting-lever K the springs expand and withdraw the stripperplate into the cavity of the grainer-disk. By cleaning the needles in this manner from time to time they are readily kept clean and in good working condition.

The cleaner or blade disk C and thegrainerdisk D rest by gravity upon the roller to be cleaned when in their working position and are'held in an elevated position clear of the printers roller by means of the levers and their supporting devices when not required for use. The blade-disk is used nearly always when operating upon a printers roller; but the needle or grainer disk is used only from time to time when the leather covering of a roller is in such a condition that it requires to be grained.

Instead of the grainer-disk D, provided with pins, as described, a grainer-disk C, such as is represented in Fig. 9, may be used. In this construction the grainer-disk is provided with blades 0', arranged as shown and described with reference to the cleaner-disk, but the blades instead of having straight or plain edges have serrated edges. The points of the teeth or serrations operate upon the leather in a way similar to the action of the needles I and produce a nice grained surface.

I claim as'my invention 1. In a machine for cleaning printers rollers, the combination of a rotary disk having in its working face one or more cleaner-blades arranged at right angles to the axis of rotation,
