Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed November 6, 1905. Serial No. 285,973.

To all whom it iota/y concern.

Be it known that .I, CLARENCE B. CUTLER, a citizen of the United States, and a resident of Stanhope, in the county of Sussex and State of New Jersey, have invented certain new and useful Improvements in Machines for Cleaning Printers Rollers, of which the following is a description.

The present invention relates to certain novel and useful improvements in a machine forcleaning printers rollers.

The invention consists in the construction, combination, and arrangement of parts set forth in and falling within the scope of the a pended claims, and while I have herein sl iown and described one articular embodiment of my invention I wish it to be understood that I do not confine myself to all the precise details of construction and arrangement set forth, as there may be modification and variation in certain respects Without departing from the spirit of the invention or exceeding the scope of the claims.

In the accompanying drawings, wherein an embodiment of my invention is delineated,

in all the views. 7

Figure 1 is a perspective view of a machine embracing my invention, certain parts thereof being broken away to more clearly disclose the mechanism. Fig. 2 is a vertical sectional view taken through the machine,

showing the washer-rollers and the scrapingblade out of contact with the roll being acted upon. Fig. 3 is a view in end elevation of the'machine, certain portions being broken away, such view intending to show the driving connections and roll-operating means. Fig. 4 is a vertical sectional; view taken through the machine, showing the scrapingblade and washingrolls operating upon the article to be cleaned. Fig. 5 is a vertical and partly in section, of the machine, certain sectional view taken through a slightlymodifled form of machine, such modification consisting in providing an additional roller adapted particularly for use in connection with machines for cleaning lithographic rollers. Fig. 6 is a view, partly in elevation parts being removed and broken away to show the arrangement of mechanism.

In providing the present machine I have especially in view overcoming certain difficulties which have heretofore been encountered in cleaning rollers used in connection with printing-presses. As is well known, after a comparatively short period of use it is often necessary to remove these rollers and clean from the same the ink and other adhering matter. The machine I have devised is particularly adapted for thispurpose and embraces the essential and desired features of compactness, simplicity, durability, and economy of installation.

Referring now to the accompanying drawings in detail, A indicates the supporting frame of the machine, which may be-of any desired and suitable character and has its leg portions preferably provided with casters 5, so that the machine may be moved from place to place. The superstructure of the machine, which is indicated as a whole by B, includes a longitudinally-disposed reservoir 0, adapted to contain the cleansing fluid to be applied to the rollers. Extending longitudinally through this reservoir is a casing D, which forms a partition practically dividing the reservoir into two longitudinally-disposed sections, said central or partition casing being provided with coverings 6 to prevent the entrance of fluid thereto. Arranged longitudinally of the machine and finding bearings at the top of the sides 7 of the superstructure I B is a track 8, upon which travels the trolley 9, carrying the depending guiding-hook 10, designed to guide and restrain one end of'the roller to be cleaned, said hook narrowing toward the bend thereof, as at 11, to enable the journals of rollers of various size to be accommodated. The aforesaid sides of the frame are grooved, as at12 12, to guide the roller betimes bearing against and supporting the printing-roll while applying the cleansing fluid thereto, a scraper mechanism comprising a screw member extending longitudinally of the machine and adapted to be thrown into contact with the surface of the printingroller to remove the coating of ink and like accumulations therefrom, a device including In order to cleanthe drying or wiping rolls adapted to be moved into contact with the printing-roller for wiping and drying the same afterthe scraping operation has been completed, the supporting or wash rolls and the scraper beihg shifted out of engagement with the roll being cleaned when the drying-rolls are moved in contact.

The construction of my machine in detail, as illustrated in the drawings, issubstantially as follows:

13 is a power-shaft journaled in the frame ofthe machine and driven from any suitable source of ower, such as the motor 14. Upon one end of the shaft 13 is. a pulley 15, connect ed by the driving-belt 16 with the large-pulley 1-7, a gear-wheel 18 being mounted upon thesame shaft as the pulley 17 and designed to turn. therewith. This gear wheel 1S meshes with two smaller gears 19-19, loose on the'ends of the-shafts or journals 20 of: the applying-rolls 21 21, said rolls extending longitudinally through the machine, one in each reservoir and adapted to be partially submergedin the cleansing fiuid'. The gears 20in -.-to be cleaned, which in the-present instance turn'mesh with similar gear-wheels 22 22, fast on theends of the journals 23 of thewasher or. supporting; rolls 24-. The ends of the roll 24 are slightly flanged,.as at 25, for thepurpose of limiting any tendency oft-he rollbeing cleaned to have an endwise movement imparted thereto during'the rotationof-the same. Ar-

. rangediabove the washing-rolls and in driving engagement therewith through the medium of the belt 27', passing over the pulleys 26 26, is the scraper of-the machine, (shown at 28,) such scraper in the present instance being in the form of' a screw and=preferably extending the length ofrthe machine. A trough, or gutter 2.9 is hunglbeneath the scraper and is provided with a gutter-spout; 30, by which the products removed from the printing-roll'by the knife may be conveyed to a suitable point. ofdischarge. From the description thus far it willbe noted that the washing-rolls andflthe scraper are connected in driving engagement and-have arotary movement imparted-theretofrom the power-shaft 13; The scraper is normally thrust forwardinto position to contact with a printing-roll'by means of'the tension-spring 28".

Within the longitudinal casing dividing the reservoir I arrange a devicecarrying a plurality of" rollers. 31, which for thesake of convenience may be termed the dryingrolls-,these-being mounted-upon heads. 32,

connected to the slot-tediposts. or rods 33', whichv project through the bottom, of'the casing-, one, near each end thereof. The

slotted-portions, 34 ofpsaid rods moveinthe.

gui'd'eways 35, formedat the ends ofthemachine, said slottedirods being connectedby the rock-shaft 36,- which also extends longitudinally underthe bed of the machine. At the bottom of the chamber, Within the reservoir, is formed'a depression 37, seating or depress the sliding rods 33, and thereby elevate or depress the drying-rollsv By reference to the drawings it will be noted that the casing forming the longitudinal chamber within the reservoir does not extend quite the entire distance of the latter, so that the ends of the drying-rolls project beyond" the ends of the chamber, and such drying-rolls are actuated. by the belting from the pulley onthe shaftof the washerrolls. (Shown in Fig. .1 at 41.) Since thebearings of the drier and ordinary rolls are connected together, as hereinafter described, their relation is. constant, no. matter what position I they occupy relative to theframe ofithenia- :chine.

In its normal working position the roller is designated as E, is placed in themachine in the manner shown in Fig; 4that is to say, assumingthe parts to occupy the relative positions shown: in said figure the roller E restsin' contact with and is supported by the washing-rolls 24 24-said roll being guided by the j ournal ethereof,fitting in one of the slots 12, while the opposite journal 6 of the rollerrestsinthe hook portion of the trolley 9. If pOWGlFbBdlOW imparted: tothe mainv drive-shaft 13, the rolls throughthe gearing and= belting heretofore described will have rotary motion imparted thereto; and

the su ply-rolls are actuated by therevolu tiono the washing-rolls. Such supply-rolls, taking'up' the cleaning fluid fromthe reservoir, Will apply the same to the wash Orsupport-ing rol s, which in turn will thorough cover-the surface ofthe roller being operated upon with suchfluid; The scraper, which is preferably'inthe form of an-Archimedean screw, being revolved by its power-transmission connections, also acts up onthe sur face of the-roller E and, scrapes OIIIGIIIOVGS therefrom the ink and otheraccumulations,

such removal: being rendered comparatively ea-syby the applicationv of thecleansing fluid, which may be kerosene or other-suitable material} The material: scraped-from the roll by the action -of-;the screw is deposited in the trough 29 and is carried toward and intothespout 30, by which'itis. conveyed to any-suitable point of 'discharge;

After the roller, has been subjected to the washing and iscra ing-"action it is desirable to dry. the samebe oreit is removed-from the machine, and this. is accomplished #bythrowing the washing-rolls and the scraper out of contact with the printing-roller, and subjecting 7 the latterto the action ofthe dryingrolls, which when not in use occupy a position within the casing D. To throw the scraper and the washing or supporting, rolls out of action and bring the drying-rolls into operation, I have constructed and correlated the parts as follows: Pivotally secured to each of the heads 32 is a pair of links43, also connected to the adjacent journals of the washing-rollers 24. Links 44 also connect both ends of the washing-rolls with the sup ply-rolls, so that a toggle-joint is formed between the drying-rolls and the supplyrolls at the ends of such rolls. Links 46 connect the ends of the scraper to the ends of one of the wash-rolls 24, so that saidscraper may be thrown out'of engagement at the desired time. To bring the drying-rolls into play and throw the washing-rolls and scraper out of action, it is only necessary toactuate the rock-shaft 36 to throw the rods 33 upward, which upward movement is assisted by the action of the springs 38. The upward movement of the heads and theirconnected drying-rolls throws-the covers of the chamber or casing D open and at the same time the link connections act to thrust the scraper and the wash-rolls outward away from the center of the machine and from contact with the printing-roller E, said roller then resting upon and being supported by the drying-rolls, as is shown in Fig. 5. The drying-rolls are rotated by the connections heretofore described, and the printing-roller E is speedily wipedand dried and mayjthen be removed from the machine. a

In Fig. 5 I have shown a slightly-modified form of machine adapted especially for use in connection with the cleaning of lithographic printing-rollers. In this instance I provide additional links, such as are shown at 46, which are pivoted to the journals of one of the wash-rolls, the movement of said links being limited by pins 47, moving in the slot 48 in the frame of the machine. This roll, which is shown at 49, is provided with a suitable napping-surface adapted-to grain or nap the roller E in a desired manner, and such roll 49 is adapted to be brought into use simultaneously With the wiping of the roll by the drying-rolls 31.

It will be noted that I have provided an exceedingly simple compact machine possessing great advantages. The machines for this purpose heretofore employed have possessed certain disadvantages, inasmuch as it was necessary to feed or move the rollv being cleaned longitudinally through the same, thus requiring the machine to be approximately at least twice the length of the printers roll. In the present'case it will be noticed that the scraping device and the rolls are so arrandged that the printing-roller may be supporte and held against endwise movement while being operated upon. It will further be seen that by use of the toggle-andlink connections controlled and operated from the rock-shaft that as soon as the roller is placed in position in the machine the supply-rolls, the washers, and the scraper may be immediately brought into operation by throwing the rock-shaft in one direction, while as soon as they have performed their functions they may be moved into an inactive position, and the drying-rolls are elevated to support and wipe the printing-roll.

By referring to Fig. 4 it will be seen that I have provided a reservoir with the side covers 60, hinged-to the sides of the reservoir at 61. When the washing-rolls are thrown back out of engagement with the supply-rolls and with the roller being cleaned, such washer-rolls will strike against the hinged covers and throw the same outward, as is shown in Figs. 2 and 5. Each of the hinged covers has upon its interior face a strip of soft materialsuch as leather, fabric, or, the like-(shown at 62,) against which the washer-roll will strike, and such rolls will be wiped dry by this strip.
