Specification of Letters Patent.
Patented Sept. 2, 1913.
Application filed August 31, 1912. Serial No. 718,094.
To all whom it may concern Be it known that I, PATRICK J. LYNCH, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Device for Cleaning Printing-Rollers, of which the following is a full, clear, and exact description.
This invention relates to improvements in devices for cleaning printing rollers, and has for an object to provide an improved construction which may be applied and removed whenever desired, applied and left in place for cleaning the rollers of a printing press.
A further object of the invention is to provide a cleaning device for printing rollers formed so as to scrape the usual supply roller with a substantially rubbing action and then deposit the matter thus scraped ed in a suitable receptacle from which it may be removed in any desired manner.
A still further object of the invention is to provide a pair of cleaning rollers, one of which is adapted to engage and scrape the usual steel roller of a printing press, and the other of which is designed to clean the scraping roller and to deposit the matter cleaned from the scraping roller in a suitable receptacle.
In carrying out the objects of the invention, the device may be applied to any desired printing press and is adapted to contact with the usual steel roller for cleaning the same, and as the steel roller is cleaned the same in turn will clean or take from the remaining rollers and the cylinder of a press the objectionable matter. During the cleaning operation the ordinary steel roller of the press is brought in contact With the scraping roller formed of composition, which in turn is cleaned by a roller formed with a scraping spiral. The composition roller is adapted to move in an opposite direction to the steel roller at the point of contact and this is also true in respect to the spirally formed roller and the composition roller, so that a proper scraping action may be had between the various contacting portions of all of the rollers. Suitable gearing is designed to be provided for accomplishing this purpose, which may be mounted on any kind of an auxiliar frame so as to mesh with the gearwhic drives the steel roller when the device is being used. If
desired, however, independent driving means could be provided for the cleaning rollers.
A. practical embodiment of the invention 1s represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indi cate corresponding parts in both the views.
Figure 1 is an end view of an embodiment of the device shown in position; and Fig. 2 is a top plan view of the structure shown in Fig. 1.
Re erring to the accompanying drawings by numerals, 1 indicates the ordinary or usual plate cylinder, and 2 and 3 indicate the usual composition rollers desi ned to shed ink on the plate cylinder 1. roller 4, known as a steel roller, contacts with the rollers 2 and 3. The cylinder 1 and rollers 2, 3, and 4, are of the usual and ordinary construction and are the members to be cleaned by the cleaner embodying the invention. Contacting with the steel roller 4; is a composition roller 5 which is supported in any desired manner and inter eared with the second cleaning roller 6. t the contact point of rollers 4 and 5 the same move in opposite directions, namely roller tmoves downwardly and roller 5 moves upwardly, so that there is a scraping and consequently cleaning action between the rollers. As the old ink is removed from the roller 4 the same, of course, is deposited on roller 5 and in order to maintain roller 5 properly cleaned roller 6 is provided. The roller 6 at its contact point with roller 5 moves in an opposite direction, namely, upwardly. The roller 6 is provided with a body 7 having spiral edges 8 preferably formed to contact with and properly scrape the roller 5. The matter scraped from roller 5 is deposited in a suitable pan or receptacle 8' which may be removed whenever desired. Gear wheels 9 and 10 are rigidly secured to the rollers 6 and 5, and a connecting pinion 11 is provided for causing the rollers 5 and 6 to turn or move in the direction desired. A pinion 12 is also provided for connecting the driving gear of roller 4 with the gear 10 of the roller 5 so as to operate not only roller 5, but also roller 6. Any desired adjustment may be provided for roller 6 to adjust the same toward and from the roller 5 without departing from the spirit of the invention, and any suitable framework may be provided for both of the rollers 5 and 6, together with their assoviatcd gearing and the intermediate pinions 11 and 12. Y
[t is understood that in the practical op oration of the above-mentioned mechanism, the rollers to be cleaned will be supplied with a quantity of fluid com ound, and the refuse will the more thoroughly be removed from the rollers thereby.
Having thus described my invention I claim as new and desire to secure by Letters Patent 1. In a cleaning device for printing presses, the combination with the rollers of said printing press, of a composition cleanr ing roller contacting with one of the r0llcrs of said printing press, a second cleaning roller, a spiral body arranged on said sec-. ond cleanin roller engaging said first mentioned cleaning roller, and means for causing all of the contact portions of all of said rollers to move in opposite directions for causmg a scraping action between each roller. 1
2. In a cleaning device for printing presses, the combination with the rollers of said press, of a composition cleaning roller adapted to engage one of the rollers of said press, an auxiliary cleaning roller formed with a spiral edge, and means for causing the contact portion of both of said cleaning rollers to move in opposite directions whereby said edge will scrape said composition cleaning roller.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
