To all whom it may concern.-

1 Be it known that we, SAMUEL CRUMP' and GEORGE SAe-Un, citizens of the United States, and residents of Poughkeepsie, in the county of Dutchess' and State of New York, have invented certain new and useful Improvements in Machines for Cleaning or Treating Printers Rollers, of which the following is a specification.

The invention relates to improvements in machines for cleaning printers rollers, such as the inking and distributing rollers of typographic and lithographic presses; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object of the invention is to provide a machine which will with certainty and rapidity efliciently remove the accumulations of ink, paper fiber, and, other matter from pinters rollers without injury to the surfaces of the latter.

In its preferred construction the machine of ourinvention comprises suitable bearings to receive and permit the rotation of the roller to be treated, a tank below the same to contain anyproper solvent solutionssuch as kerosene, naphtha, or benzin for typographic rollers, and turpentine for lithographic rollersa rough-surfaced roller to engage the surface of the printers rollers and impart rotary motion to the SQF'CG, a brush for applying the solvent to the printers roller, and a series of novel scraper-blades against the edges of which the'printers roller will be rotated and which will effectively remove the ink and foreign matter therefrom, leaving the surfaces of the said roller clean and dry and ready for renewed use in a press. The scraper-blades of our invention are of special importance in that they are obliquely arranged with respect to the printers roller and present concave edges to the surface of same, which edges are on a concave or segmental line or arc of a circle greater in diameter than the diameter of said roller, whereby said edges are enabled to pass on oblique lines, partly around the roller and, due to the relative relation of the blades to one another, clean the entire surfaces of the roller during the rotation of the latter. We prefer to arrange the scraperblades in series and pivotally mount them so that they may be correspondinglyadjusted as to their obliqueness to the roller, whereby the blades may by simply turning them on or with their pivotal supports be adapted to the special conditions of the rollers to be cleaned and especially to the varying diameters ofthe rollers, one set of the blades being adapted without change other than adjustment obliquely for cleaning rollers. materially varying in diameter.

The nature of the invention. and satisfactory means for carrying the same into effect will be fully understood from the detailed description hereinafter presented, reference be ing had to the accompanying drawings, in which Figure 1 is a front elevation of a machine constructed in accordance with and embod ringour invention, a printers roller to. be cleaned being shown in position on. the machine. Fig. 2 is an end elevation of same. Fig. 3 is a top view of same. Fig.4 is a top view, partly broken away, of that portion of the machine affording bearings for the ends of the printers roller, which is also represented in Fig. 4. Fig. 5 is an end projection, partly in section, of same. Fig. 6 is an enlarged end elevation of a portion of one of the bearings for the printers roller, the shaft of the latter being shown in section. Fig. 7 is a top View of a portion of the machine and is presented to represent 11? ore particularly the brush. and the mechanism for m oving the san" efrom the solution-tank into contact with the printers roller. Fig. 8 is an end projection of same. Fig. 9 is a top view of a portion of the machine and illustrates more especially the series of pivotally-m ounted scraper-blades and the means for adjusting them to the desired or necessary oblique position with respect to the roller to be treated. Fig. 10is afront elevation of sante. Fg. 11 is an end elevation of a portion of same, and Fig. 12 is a detached view of one of the scraper-blades provided with a serrated edge.

In the drawings, designates the side frames of the machine,which frani es are suitably connected together by rods in a familiar manner and support between them an elongated receptacle or tank 21 for holdingthe solvent or solution to be applied to the printers rollers for softening the matterthereon.

In the upper ends of the side frani es 20 is mounted a rod or shaft 22, upon one end of which is mounted to rotate thereon the driving-belt wheel 23 and driving gear-wheel 24,

these wheels being connected together by a sleeve in a familiar manner.

IIO

Upon the rod 22 is secured a pair of forwardly-projecting arms 25, Figs. 1 and 3, in the front ends of which are loosely mounted so as to rotate therein the reduced ends or shaft 27, Fig. 2, of the roller 26, the latter having a roughened surface and being thereby adapted by its surface contact with the printers roller 28 to rotate the latter.- On the left-hand end of the shaft 27 is secured a gear-wheel 29, which is in constant mesh with the gear-wheel 24 and receives motion from the latter and communicates the same to the roller 26. I

Upon the rod 22 is also secured a lever arm30, which may be utilized through the rod 22 and arms 25 in elevating the roller 26 from the printers roller 28 and moving the said roller 26 to the back of the machine, the

- gear-wheel 29 during such action rolling upon thegear-wheel24.

The shaft 31 of the printer s roller 28 has its ends cradled in the bearing-loops 32 of the frames 33, Figs. '1, 2, 4, 5, and 6, wherein are provided rollers 34, upon which the ends of said shaft 31 have a bearing. The frames 33' are bifurcated at their rear ends, Figs. 4 and 5, to straddle and rest upon the rod 35, connecting the side frames 20, while at their front ends the said frames 33 rest upon the front edge of the tank 21. The frames 33 maybe slid toward and from each other, and thereby become readily adapted for the varying lengths of printers rollers. We regard the bearing-loops 32, having the bearingrollers' 34, as o importance in view of the readiness with which the printers rollers may be introduced into and removed therefrom and the ease and trueness with which said rollers may be rotated therein.

Upon the inner or facing sides of the side frames 20 are provided vertical guide-lugs 36, in vertical apertures in which are mounted the sliding rods 37, which are connected at their upper ends by a cross-bar or frame 38, Figs. 1, 9, 10, disposed above the tank 21 and carrying the longitudinal series of pivotallymounted overlapping scraper blades 39. The scraper-blades 39 have concave scraping edges 40, and these edges are on the arc of a circle greater in diameter than the diameter of the roller to be treated, and this is an important feature of the invention in that thereby the said blades become adapted for the cleaning of rollers varying materially in diameter and may be arranged on oblique angles to the longitudinal axis of said rollers, as illustrated in the drawings. The blades 39 are in the present instance formed of sheet metal and are fastened by screws, Figs. 9, 10, and 11, to

suitable heads 41, fashioned upon the upper ends of the pins or pivots 42, which extend downwardly through apertures in the bar 38 and have secured upon their lower ends the crank-arms 43, which project rearwardly and are connected in a pivotal manner at their outer ends with the rod 44, by which simultaneous movement may be imparted to the crank-arms 43 and through said arms and the pins or pivots 42 to the scraper-blades 39. The left-hand head 41 has formed on or connected with it a leverarm for manual manipulation, and upon reference to Fig. 9 it will be understood that when the lever-arm 45 is moved to the left or right its movement will be communicated through the left-hand pin or pivot 42 to the left-hand crank-arm 43, and thence through the connecting-rod 44 to all of the remaining crank-arms 43, with the result of correspondingly moving or adjusting all of the scraper-blades 39 with respect to the angle at which they shall stand. Below the lever-arm 45 We provide a segment 46, having a series of serrations 47 to enter into locking engagement with a spring-detent 48, carried by the lever-arm 45, the purpose of the serrations 47 and detent 48 being to lock the leverarm 45 in any of its adjusted positions, and thereby lock the scraper-blades 39 in such position as may be given to them.'

The guide-rods 37 and connecting crossbar 38 constitute a frame which carries all of the scraper-blades 39, and this frameis movable vertically so that the blades 39 may be conveniently moved toward and from the printers roller 28 and be adjusted to suit the special condition of the roller to be treated and the varying diameters of rollers which may be applied to the machine for treatment. The frame carrying the scraper-blades is therefore vertically movable and it may yield to the printers roller to be treated. The mechanism by which the frame carrying the scraper-blades 39 may be manually raised and lowered comprises a rock-shaft 49, mounted in bearings 50, formed in the side frames 20, crank-arms 51, secured on said roclcshaft, Figs. 1 and 10, links 52, pivotally connected to said crank-arms 51 and the guide-rods 37, a lever 53, secured to said rockshaft 49 for turning the latter, and a counterbalance 54, also secured to said rock-shaft 49. When the lever 53 is pushed downwardly, it will turn the rock-shaft 49 toward the front and cause the crank-arms 51 thereon to turn downwardly and through the links 52 pull the guide-rods 37 downwardly, thus lowering the cross-bar 38 and series of scraperblades 39. When the lever 53 is pressed upwardly, it will reverse the motion of the rockshaft 49 and crank-arms 51 and effect the upward movement of the guide-rods 37 bar 38, and scraper-blades 39. The tendency of the counterbalance 54 is .to move the rods 37 and bar 38 upwardly with a yielding pressure, and the said counterbalance 54 is of such Weight as to practically balance the Wei ht of the scraper-blade frame, whereby said ame becomes sensitive and easily moved and c apable of ready manipulation. I

In the operation of the machine we preferably apply the solvent solution to the rollers to be treated by means of a rotary brush,.and in the drawings this brush is designated by the numeral 63, Figs. 7 and 8. The ends of the shaft 64 of the brush 63 are loosely journaled in the rear ends of crank-arms 65, fastened upon a rock-shaft 66, whose ends are journaled in bearings 67, formed in the side frames 20. Upon the rock-shaft 66 is secured a lever-arm 68, by which said shaft is given its rocking movement for the purpose through the crank-arms of moving the brush 63 upwardly from the tank 21 intocontact with the printers roller 28 when the latter is in positionand it is desired to apply the solvent thereto. When the lever-arm 68 is pressed downwardly, it will cause the rockshaft 66 to be turned toward the front and the brush 63 to be elevated against the roller 28 and when the lever 68 is allowed to move upwardly the rock-shaft 66 will. have a re verse motion and the brush 63 will descend into'the tank 21. The brush 63 is caused to rotate when in contact with the printers roller 28 simply by its engagement with said roller, which is rotated by its contact with the rough-surfaced driving-roller 26. We do not of course limit our invention to the rotary brush 63 nor to any special means for applying the solvent or other solution to the printers rollers to be treated.

In the operation of the machine hereinbefore described we will first adjust the bearing-frames 33 to suit the particular length of printers rollers 28 to be treated, and in this operation either one or both of the frames 33 may be adjusted in accordance withthe particular conditions to bemet. Prior to introducing the roller'28 to the bearing-frames 33 the scraper-blades 39 will be moved downwardly and the roughened roller 26, if then at the front of the machine, will be turned rearwardly by means of the lever-arm 30, so that it will be at the rear of the machine. At this time also the brush 63 will be in its lower position. After the printers roller 28 has been introduced I to the bearing-frames 33 the roughened roller 26 will, by means of the lever 30, be turned to the front of the machine and allowed to rest upon the printers roller 28, as shown in Fig. 1 ,the scraper-blades 39 still'being in their lower position. Power being applied to the band-wheel 23, the rough-surfaced roller 26 will be set in motion by means of the gear-wheels 24 29 and will impart rotary motion to the printers roller 28. After the roller 28 has been set in motion the solvent should be applied to the same, and therefore the attendant will press downwardly on the lever 68 and cause the brush 63 to ascend into contact with the roller 28, which then rotating will rotate the brush 63, with the result that the entire surface of the printers roller 28 will become covered with the solvent, which will loosen the accumulated matter upon said roller. The brush 63 maybe raised and lowered asfrequently as may be required in accordance with the amount of solvent it may be found necessary to apply to the printers roller. The seriesof scraper-blades 39 may now be elevated into contact with the printers roller 28 and given any desired adjustment on their axes in accordance with the diameter and condition of said roller, it being understood that said scraper-blades must always have an oblique position and that they must overlap, as shown in Figs. 9 and 10, so that the entire surface of the roller 28 may be subjected to their action. The rotation of the roller 28 against the scraper-blades 29 will be continued until said blades have efficiently removed all of the foreign matter from said roller and said roller is left clean and dry and ready for further use in a press. The concave edges 40 of the scraper-blades 39 are beveled, as shown. in Fig. 11, to approximately aknife-edge, and hence, notwithstanding the oblique angle at which the scra erblades are placed, said blades are enable to efiiciently engage a rather extended surface of the printers roller 28 and rapidly and efficiently clean and dry the same. In Fig. 12 we show one of the scraper-blades 39 as being formed along its beveled'concave edge with serrations, and this form of blade may be used in the treatment of lithographic rollers for napping or graining the same. For the customary work of cleaning rollers for typographic presses we shall employ the smoothed ed blade shown in Fig. 1 1.
