N. 5. A CORPORATION CF PRINTING-PRESS.

To all wle. am it may concern:

Be it known that we, SAMUEL CRUMP, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, and ADIN W. HIL- srnenn, a citizen of the United States, residing in Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in or Pertaining to Printing-Presses, of which the following is a specification.

The invention relates more particularly to novel means for enabling the effectual automatic cleaning or Washing of the ink distributing and form rollers, forms and other portions of printing pr sses to which the ink may be applied, either directly in the proper operation of the press or by offsetting, as in the case of tympans and angle bars or web supporting and directing rollers of printing machines of the perfecting type, Without removing any of the rollers or other parts from the press and While the same are driven by the press driving means;

Our invention may be built in the press or printing machine or be embraced in an attachment to be applied thereto. We preferably embody the invention in the'form of an attachment which may be readily applied to presses already in use.

Our invention is based on the conception of cleaning all of-a train of rollers of a press, as well as the form,'while they are on the press and whether they be many or few, simultaneously, quickly and effectually.

The operation or method of utilizing our invention is based on the principle of transferring the ink or color from one roller to another or from one inked surface to another in series through the chain of rollers or surfaces to a final uninking or draw ofl' roller, which is preferably a rollermade of printers roller composition, from which it is removed by a scraper or scrapers held against the same, said uninking roller-being mounted "in a suitable receptable containing a solvent of ink, provision being made for applying the uninking rollento one of the inked surfaces to be cleaned and idisengaging the same therefrom after the cleaning operation has been completed 'lhe invention is applicable to flat bed p gases and cylinder presses with equal eiiiciencyif 'lhe an Specification of Letters Patent.

' inking rollr to which faces on the Patented Sept. 21, 1915.

Serial No. 14,056.

the scraper is applied being constantly become the point of delivery for the ink from all of the other rollers or surfaces in the train and in an almost incredibly short deprived of its ink, will timeall the ink on said rollers or surfaces will transfer to said uninking roller and be removed, all .of the rollers and inked surpress becoming thoroughly cleansed. and also dried of the kerosene or other solvent which we will pour on the rollers during the cleansing operation for softening the ink. The form rollers will be" A left in contact with the form during the cleansing operation when it is desired that the form shall be cleaned at the same time that the rollers are being cleansed.

The invention may be applied to the tympan or angle bars of a perfecting press with entire efficiency as will be hereinafter explained.

One of the most difiicult problems in cleaning the rollers and inked surfaces of a printing press is to remove the fine paper (lust therefrom, this dust adhering with great tenacity to the rollers, and one objee't attained by our invention is the removal of such paper dust with absolute efficiency and without injury to the rollers.

The invention resides in the novel f atures, arrangements and combinations of partshereinafter described and particularly pointed out in the claims, and the invention will be fully understood from the following specification, reference being had to the accom'panying drawings, in which:

- 16 is a detached top view of the receptacle enumerated being usual to flat bed presses or tank for the uninking roller shown in- Figs. 12 and 15; Fig. 17 is a vertical section throu h the same, taken on the dotted line 17-4? of Fig. 1c, and Fig. 18 is an .end view of the same.

In the drawings, 25 denotes a portion of the side of a flat bed press, 26 the form, 27 ink rollers for the form and 28 a driving gear common to flat bed presses and traveling with the bed, said gear wheel 28 receiving'its motion ordinarily from a rack bar on the frame of the press,-all these features Our attachment comprises side frames 29,

which are ,connected together by the rods and shaftshereinafter referred to, hooks 30 on a rod 31 connecting said sides, and legs 32 (Fig. 2) on the attachment adapted to rest upon the sides 34 of the press frame. The hooks 3O constitute the meansfor connecting the attachment to the frame of the press, and-these hooks when the attachment is in position engage a transverse rod 35 rigid with the frame of the press, as shownin Figs. 2 and 8. Our attachment further comprises a receptacle 36 for solvent and refuse cleaned from the inked surfaces of the press, an impervious, smooth-surfaced uninl-zing roller 37 partly confined within said receptacle and adapted to be engaged by scraper blades 38 secured within said receptacle, a roller 39 which engages the form and a transverse roller 40 which engages both the

rollers

37, 39 and rotates by friction, the

rollers

37, 39 preferably having printers roller composition outer portions, as shown in Fig. 8, and the roller 39 serving to transfer the ink from the form to the roller 40 and from this roller the ink or color is drawn off by the rotating roller 37, from wliich'the ink or color is constantly removed by the scrapers 38. We provide for the rocking or oscillating of the receptacle 36, so that first one scraper blade 38 and thenthe other may be positioned for use against the uninking roller 37 in accordance. with the direction of motion of the form 26,

In Fig. 8 we illustrate the. roller 39 in position engaging the form 26 and the roller toward the press mechanism clear of the roller 37, as represented by dotted lines in Fig. 9.

The. receptacle 36 is in the form of an elongated trough extending transversely of the press and its details are probably more clearly illustrated in Figs. 8, 10 and 1.1. The receptacle 36 comprises sides 41, ends 42 and

trunnions

43, 44, the trunnion 43 being solid and the trunnion 44 tubular. The tubular trunnion 44 is mounted in a tubular bearing 45 secured to the side frame 29 and which side frame is made hollow in line with said trunnion 44 and receives a coupling 46 connected with a pipe 47. The outer end of the opening or chamber 48 within the side frame 29 is closed by a cap 49. The end of the receptacle 36 has surrounding the tubular trunnion 44 an annu lar groove 50 which receives the inner edges of the tubular bearing 45 and is provided with a packing 51 so as to for-m a liquid tight joint between thetrunnion 44 and bearing 45. At the opposite end of the receptacle 36 the trunnion 4-3 is mounted in a bearing sleeve 52 and is pressed against by a coiled spring 53, the function of the spring 53 being to press the receptacle 3G in a direction toward the bearing sleeve 45 and against the packing 51, thereby maintaining secured the lower edges of the scraper blades l in securing the blades and the blades and '38 and strips 55, said strips serving to aid strips being detachably fastened in said grooves by means of screws 56. The blades are of thin metal capable of limited flexion and they may be securely fastened in place by means of the grooves 54, strips and screws 56. The blades 38 extend upwardly adjacent to the sides of the receptacle 36 and at their upper edges are formed with inwardly turned lips -57which alternately engage at their edges the surface of the roller 37 during the use of the attachment one flat bed press and stand clear of said roller when the attachment is not in use. The lips 57 are deflectedilaterally from the body of the scrapers 38, and this particular construction of scraper we have found to be highly efficient in cleaning the roller 37 so that a clean dry surface of said roller may be constantly presented to and draw ofi ink or color from the roller 40. The bottom of the receptacle 36 is hollowed out, as at -58, for convenience in reaming out the grooves 54.

The roller 37 has its shaft 59 mounted in bearings, as at 60, in the sides 29 of the attachment, and on this shaft is a gear wheel 61 by which power-is transmitted, as herelnafter explained, to rotate the roller 37.

The gear wheel 61 is in mesh with a pinion wheel 6% (Fig. 1) secured on a shaft 63 on whose outer end is a gear wheel 62 (Fig. 2) in mesh with an intermediate gear wheel 65 which is in mesh with a gear wheel 66, and said gear wheel 66 is in mesh with a gear wheel 67. The gear wheel 67 is adapted to be thrown into engagement with the gear wheel 28 hereinbefore described, when the attachment is to be placed in operation and to be elevated from said gear wheel 28 when the press is not to transmit its motion through the train of gear wheels just doscribed to the gear wheel 61 on the shaft of the uninking roller 37. The gear wheel 67 has its stud shaft 68 (Fig.1) mounted in a bearing in the outer end of a bracket arm 69, at whose inner end is a sleeve 70 swiveled i on the rod 35. The swiveled arm 69 is'con n'ected by a pin, as shown in Fig. 1, with one end of a link 71, whose other ends 1s pivotally secured to the lower arm of a bell crank lever 72, the upper arm of which is pivotally connected with the inner. end of a long link 73 which extends outwardly and is pivotally secured to an arm'74lhaving a sleeve 75 securing it upon a shaft 76. The

shaft v76 has at one end an exposed handle- 77 by which the shaft may.- be turned or oscillated. When the handle 77 is turned inwardly or toward the body'of'the press, it will give the shaft 76 a partial rotation and cause the arm 74 to push against and move the link 73 inwardly and this link will turn the bell crank 7 2 inwardly and downwardly and through the link 71 cause the arm 69 to move inwardly and downwardly and carry the gear wheel 67 into mesh with the gear wheel 28 constituting a portion of the drivthe end thereof not shown in Fig. 1 but corresponding exactly with the gear wheel 61 shown in Fig. 1., an intermediate gear wheel or idler 78, shown by dotted lines in Fig. 2,-

and a gear wheel 79 secured on the shaft of the roller 39 and being in mesh with the in termediate gear wheel 78. The bell-crank lever 72 is swiveled on a rod 80 and on this rod, which is mounted. in bearings 81 in the side frames, 29, is secured a lever 82 which.

extends outwardly and curves downwardly and then inwardly and affords a bearingvfor the shaft 83 of the doller 39, as shown by dotted lines in Figs. 2 and The rod or shaft 80 will extend transversely across the attachment and at each side of the attachment will be one of the levers 82 so that the shaft of the roller 39 may he supported at both of its end portions. The levers 82 are connected with the shaft 76, and said levers one at each side of the attachment, are provided not only to afford bearings for the roller 39, but as means for permitting the elevation of said roller from its position shown in Fig. 8, in contact with the form 26, to the position shown in Fig. 9 and also in Fig. 2, in which it may be seen that the roller 39 is slightly elevated above the form 26. To each lever 82 is pivotally secured (at 84:) at its inner end a lever 83, which extends outwardly and at its outer portion has a curvedarm 85, which is directly over a pivoted cam-dog 86 secured on and therefore movable with the shaft 76 by the manual operation of the handle lever 77. The levers 83 have ournaled in them the shaft of the transfer roller 40, said shaft being numbered 87 in Fig. 2. The lower end of the dog 86 is rounded and adapted to engage and rest on the frame of the press, and when the shaft of said lever and the roller l9 carried there by, and also, from its lower end, elevate the shaft 76 and lever 82 to lift the roller 39 from the form 26, the roller 39 being thus disengaged from the form 26 and the roller 40 from the

roll rs

39, 37 or to the relative positions 'illustra ed in Fig. 9. When the

rollers

39, 40 are lthus placed out of operation by the turning of the shaft 76 to elevate the levers 83 and levers 82, the arm 74 becomes turned outwardly with the shaft and i by pulling on the link 73 effects through the bell-crank 72, link 71 and arm 69 the .elevation of the gear wheel 67 from engagemen with the gear wheel 28 of the press, and thus when the rollers of the attachment are placed out of operation, the gearing leading to them from the gear wheel 28 becomes disengaged from said gear wheel 28 and said rollers of the attachment come to rest, The shaft 76 will have a cam-dog 86 near each end so that the

levers

82, 83 at each side of the attachment and the

rollers

39,40 con nected withthem may be correspondingly and evenly elevated and lowered when the shaft 7 6 is turned to effect these results.

Since the bed of the press has reciprocating or reverse movements and communicates such movements to the gear wheel 28, a re verse rotation or oscillation will be imparted from the gear wheel 28 to the train of gears leading to the

rollers

37, 39, and since the roller 37 has reverse movements imparted to it, it is necessary or at least highly de sirable that two of the scraper'blades 38.

be employed so that when the roller 37 is rotating in one direction one scraper blade may engage the same and when the roller is rotating in a reverse direction the other scraper blade may engage the same. In Fig. 8 we illustrate at the left hand side thereof one scraper blade 38 engaging the roller 37 while the other blade is free of said roller, and it will be understood. that when the said left hand blade is engaging the roller 37, said roller is rotating upwardly and toward the right, so that thelip 57 on said blade may act as a broad hook to clean the upwardly traveling surface of sa droller. In order to effect the alternate engagement of the scraper blades 38 with the roller 37 in conformity with the reciprocations of the bed of the press, we provide for the oscillation of the receptacle or trough 30. such oscillatory movement of such receptacle or trough belng colmnumcated to it from the shaft 59 ofthe uninking roller 37 through intermediate connections more clcartv represented in Figs. 1 and 3 to 7 inclusive, in which 88 denotes a pin secured to and extending from the upper corner of one end of the receptacle 36 and 89 a crank arm secured on the inner end of the shaft 90 and having a slot 91 transversely confining the pin and permitting said arm to have a rocking motion with the shaft 90 Without a bell crank 94 secured on the shaft 90, and

other features hereinafter mentioned corfined within said cup-disk 92 and housing 93. Upon the shaft 59 is a bushing 95, and the cup-disk 92 has a tubular section 96 mounted on said bushing, being secured thereto and to the shaft 59 by means of a set screw 97 shown in Fig. 5. The housing 93 has a tubular section 98 which is mounted on the bushing 95, and the outer end of said bushing is flanged over on the housing, as at 99, to retain-the housing in position. The housing 93 is somewhat elongated and at one end has a hearing, as at 100, on the shaft 90. The bell crank 91 has upper and

lower arms

101 and 102, respectively, and these arms carry

rollers

103 and 104, respectively,

which extend laterally within the housing 93. lVithin the cup-disk 92 and engaging the inner lateral wall thereof is confined a grip or clutch spring 105, this spring being in the form of a split ring separated at its ends and at said ends formed with inwardly extending arms 106 'and 107, respectively, which arms are separated from each pther and have substantially parallel facing surfaces defining a space within which is confined a pivoted wedge block or key 108 carried by an oscillatory arm 109 which arm is within the housing 93 and at one end swiveled upon the sleeve section 98 of said housing, said sleeve section 98 extending; as shown in Figs. 5 and 6, into the cup-disk 92 and said arm 109 having a sleeve section 110 which snugly but with freedom for motion fits .upon the sleeve section 98 of the housing 93 and extends into the disk 92. In Fig. 6 the numeral. 111 indicates the pin by which the block or key 108 is connected with the arm 109: The arm 109 has a rounded outer end or cam surface 112, and upwardly and downwardly extending

arms

113 and 114, respectively, and said arms are slightly concaved and merge into the convex outer surface 112 The outer surfaces of thearm 109, including the arms 113, 11%, are engaged by the rollers 103. 104: of the bell crank 94, as may be seen in Figs. 3 and t, and in the operation of the machine said arm 109 has an oscillatory motion imparted to it and daring such'motion carries its outer end Whose movement is imparted through the crank 89 and pin 88 to the receptacle 36.

Upon the sleeve section 110 of the oscillatory arm 109, are mounted two disks 115,

116, respectively, having ona segmental portion of theiredges gear

teeth

117 and 118, respectively, and being also formed with radially projecting

arms

119 and 120, respectively. The gear teeth 117 of the disk 115 are in mesh with a pinion Wheel 121 which overlaps and is thereby placed in mesh with a corresponding pinion Wheel 122 in engagement with the gear teeth 118 ofthe disk 116. The pinion wheel 122 is secured upon a stud shaft 123 having a bearing in a sleeve 124 (Fig. 7), constituting an integral portion of the housing 93. The pinion Wheel 121 is secured on a pin 125 having a bearing in a sleeve 126 formed in tegrally with the housing 93, and said pin at its outer end is secured to a crank arm 226 whose upper end is connected by a link 127 with a crank arm 128 connected by a sleeve 129 with the rock shaft 76. The aforesaid operating handle 77 is connected with said shaft 76, and When said handle is turned in one direction it will rotate the '1 pinion wheel 121 in that direction and said pinion Wheel will impart its movement to turn the disk 115 in a reverse direction and also operate to rotate the pinion wheel 122 in a reverse direction and cause said pin-ion wheel 122, engaging the gear teeth 118, to turn the disk 116 in a direction reverse to the movement of said pinion wheel 122. The eflect of the reverse movements of said pinion wheels 121. 122 is to turn the

disks

115 and 116 in directions to either cause the arms 119 and 120.thereof to approach each other or to the position shown in Fig. 4 or to rccede from each other or to the position shown in Fig. 3.

When the

arms

119, 120 are to approach each other they engage the

arms

106 and 107 of the spring 105 and when in such position their pressure against said

arms

106, 107 serves to contract the spring 105 sufii ciently for said spring to release firm engagement of itself with the inner walls of the disk 92. Fig. 4 shows a neutral position of the arm 109

withthe arms

119, 120 of the

disks

115, 116 in engagement with the arms 106,107 on the spring 105, while Fig. 3 shows the extreme movement of the arm 109 in one direction for turning the receptacle 36 for one limit of its movement, and, as shown, in such condition of the machine, the arm 106 of the spring 105 is against a stationary stop 130 formed on the housing 93; when the arm 109 is in its other extreme position the arm 107 on the spring 105 will engage the stop-arm 131 also formed integrally with the housing 93.

When by means of the handle 76, arm 128 and link 127 the

gear Wheels

121, 122 turn thedisks 115 and 116 to carry their

arms

119, 120 against the

arms

106, 107 of the arm 109 or to the neutral position shown in Fig. 4, said

arms

119, 120 will contract the spring 105 and leave the mechanism in the condition represented in Fig. 4, with the receptacle 36 at rest; but when the handle arm 77 is turned to separate the arms119, 120 from the

arms

106, 107 of the spring 105, the spring will expand suificiently to pass into engaging relation With the rim of the disk 92, and thenthe'cup-disk 92 will be rotated from the shaft 59 of the roller 37, and a rocking motion will be imparted to the shaft 90 and through said shaft and intermediate connections to the receptacle 36. During the rotation of the shaft 59 and disk 92 in onedirection, the spring 105 Will be carried thereby until, say, the arm 106 reaches the stoparm 130 and becoming arrested thereby the spring is caused to sufiiciently contract to release its engaging relation with the rim of the disk 92, and upon that taking place the disk 92 may have a further rotary -motion regardless of the spring 105. The travel of the spring 105 with the disk 92 until the spring reaches the stop arm 130 is. to effect that movement of the arm 109 which will, through the bellcrank lever 94, rock the shaft 90 in one direction-to tilt the receptacle36 and thereby move a scraper-blade against the roller 37, and the continued rotation of the disk 92 while thespring is against the stop-arm 130, is to permit the uninking roller37 to continue its rotation against said scraper blade so as to perform its duty and be cleaned by sai blade.

When the ,echanism of the press is reversed the roller 37, shaft'59, and disk 92 will imme iately have a reverse rotationv and the arm 106 of the spring will be released from the stop arm 130 and the spring 105 will expand into binding relation with the rim of the disk 92, said springthen taking the direction of motion of said disk and carrying its said arm 106 against the wedge or key 108 pivotally carried by the arm 109, with the result that due to the resistance of the arm 109, there being a load on it, the wedge or key 108 will be turned slightly on its pivot and wedged between the

arms

106 and 107 and not only cause the spring 105 to more tcnaciously engage the rim of the disk 92 but insure the downward movement of the arm 109 under the force exerted against it by the arm 106 of the spring. The pressure of the spring against the Wedge or key 108 will not become relaxed until the outer cam surface 112 of the arm is against the roller 104 of the bell crank 94 nor until the arm 107 of the spring has become arrested by the sto arm 131. When the .arm 107 reaches the stop arm 131 the spring will become arrested thereby and the continued rotation of the disk 92 coupled with the resistance offered by the stop arm 131 will result in the contraction of the spring 105 to the proper extent for enabling the uninking roller 37 to continue in motion against the scraper blade brought against it during the downward movement of the arm 109. When the press mechanism is again reversed the spring will leave the stop arm 131 and move upw'ardly with the disk until said spring again becomes arrested by the stop arm 130 and thereupon the uninking roller and disk 92 will continue in motion. The upward travel of the spring toward the stop arm 130 will result in the two arms of the spring turning the wedgeor key 108 to a position in which it will be wedged between them and bind the spring more tightly against the rim of the disk 92 and'assure the due upward return of the arm 109 in opposition to the load upon it due to the crank arm 94: and the connections leading to the receptacle 36.

at the left hand "side of Fig. 8, 'so as to The receptacle 36 is tilted in one direction during the upward movement of the arm 109 and in the reverse direction during the downward movement of said arm 109, and in each instance, after the receptacle 36 has been tilted-to carry a scraper blade against the roller 37, said blade remains stationary and the roller 37 continues in motion until on a reversal of the press mechanism thearm 109 is moved to its opposite position to effect the tilting of the receptacle 36 and the carrying of its other blade against the roller 37 ,when again the receptacle will re main stationary and the roller 37 continue in motion.

When a scraper blade is moved against the roller 37 it becomes slightly flexed, as shown effectually clean the roller. One very desi'rable feature of the operation is that'at the moment the press mechanism reverses and the mechanism of our attachment becomes rerversed thereby, the spring 105 leaving the

stop arms

130, 131, respectively, acts a little more quickly than the arm 109, and

the result of this is that the roller 37 on its reverse movements and just at the very beginning of such movements, rotates 'downform of the press the handle lever 77 will had been serving to clean the roller 'is to permit the roller to wipe from the edge of the blade any solventor other matter which might remain on such edge and finally transfer to the roller on the next reverse'move;

downward stroke the edge of the scraper blade which ment when the blade is returned to the roller.- One object of the invention is to prevent the solvent from reaching the upper surfaces of the roller and to at all times present a clean dry roller surface to the transfer roller 40 or other roller or surface which may be engaged by the uninking roller.

In the employment of the attachment 8. suitable solvent of ink will be supplied to the receptacle 36 as represented in Fig. 8,

form and its engagement with the roller preventing the solvent from rising above the scraper blade and said edge 57 serving during the rotation of the roller to efiectually clean the same, removing therefrom the ink or color together with the solvent adhering -to the roller. It is one of the import-ant featuresof the invention that a solvent" of ink or color is placed within the receptacle 36 to cooperate with the scraper blade or blades in cleaning the uninking roller and in getting said roller to present a clean dry surface to the surface from which ink or color is to be transferred thereto. The solvent may be supplied to the Fig. 15 we illustrate suitable mechanism for this purpose, which mechanism will be hereinafter described in connection with the construction shown in Fig. 15. The operation at the attachment hereinbefore described will largely be understood description.

without 'further elaborate When the attachment is not to be usedthe handle lever 77 will be turned in one direction to separate the gear wheel 67 from the" gear wheel 28 of the press and separate the roller 40 from the roller 37 and roller 39 and the roller \39 from the form 26, and thereupon the press may continue in opera,- tion without regard to the attachment. \Vhen it is desired to clean. the rollers and be turnedl'n a reverse direction to lower the gear wheel 67 into engagement with the p gear wheel 28 and lower the pick-upland transfer roller 39 into engagement with the 'form 26 and the roller 40 into engagement roller 39 to the roller 40'from which it will be drawn 05 by the roller 37, whence the ink or color will be removed by one scraper blade or other in accordance with the direction of motion of the form 26.- During the.

use of the attachment the receptacle 36 will be oscillated in the manner hereinbefore described so as to alternately carry the scraper blades 38 against the roller 37.

The invention is applicable to various types of presses and in Figs. 12 to 18 inclusive we illustrate a modified form of the graphic varnish in sullicient quantity to reach the first form roller, and run the press for about three minutes to work off the paper dust; after this we stop the press, throw on the uninking roller, apply solvent again and run the press with the uninking roller in position until the form is absolutely dry; then we throw off the uninking roller promptly and drain the solvent fromthe uninking roller receptacle.

One of the most difficult problems in cleaning a press is to detach and remove the paper dust which gathers on the inked surfaces, and in accordance with our invention we are able to efiectually accomplish the removal of this paper, dust, as well as the ink or color. We shall also employ our invention-in connection with the tympan, applying solvent to the tympan and placing the uninking roller in engagement with the surface of the tympan, so as ,to remove offset therefrom. \Ve shall also apply our invention to the angle bars or rollers of a web perfecting press so as to remove offset therefrom.

Referring to Figs. 12 to 18 inclusive we therein illustratea modified embodiment of the invention and will proceed to describe the details of the same. The uninking roller is designated in this modification by the numeral 140 and the receptacle for solvent and refuse taken from the roller is numbered 141. The uninking roller 140 may engage any inked surface of a press or printing machine requiring to be cleaned, but we illustrate the same in Fig. 15 as in engagement with the ink-distributing drum 142 of usual character in certain types of presses. The scraper blade is designated by the numeral'143 and is fastened to a bar 144 hav ing shaft end portions 145 suitably journaled in bearings 146 and'having 'on their outer ends eccentrics 147 resting on the side supports 148. The scraper blade bar is equipped with a handle 149 by which it may he turned to its operative position shown 1n Fig. 15 or back from the roller 140 to an inoperative position. receptacle 141 may be supplied from a tank 150 having anoutlet pipe 151 connected with a valve casing 152 containing a threeway valve 153 and communicating with a pipe 154 leading to the receptacle 141 and -with a waste discharge pipe 155. After .the

attachment has been in use and it is desired to leave the same in as cleana state as POSSl The solvent for the ble, the three-way valve 153 will be turnedto the position shown in Fig. 15', in which position the tank 150 and receptacle 141 may.

be discharged of'their contents. I Should the three-way valve 1 be turned so that its through passage is transverse of the casing 152 and its short passage extended downwardly, the receptacle 141 alone will be drained without any discharge from the tank 150; and when the valve 153 is turned so that its short passage extends upwardly, the tank 150 may dischargeits contents into the receptacle 141. The receptacle 141' is supported at its ends on arms 156 which are fastened by screws 157 to-side bars 158 and have upturned inner ends set Within sockets 159 extending from the ends of the receptacle 141 and serving as means for supporting said receptacle upon the inner ends of said bars 156. The uninking roller 140 has end shaft sections 160 which are mounted in bearings 161 on the side bars 158, and one of said shaft sections has secured upon it a gear wheel 162 by which the uninking roller will be driven. When the'uninking roller 140 engages the ink-distributing drum. of the press, the gear wheel 162 may be placed in mesh with the usual gear on said drum and derive motion therefrom. The roller 140 will remain in engagement with the inkdistributing drum 142 only during the time that said roller 140 is in use cleaning the inked surfaces of the press, and hence it is desirable that the attachment be so applied to the press that it mav be raised to effect the engagement of the roller 140 with the drum 142 and lowered to carry said roller from said drum when theattachment is to be placed out of commission. We therefore support the receptacle 141 and roller 142 on side bars158 which may move downwardly to the extent permitted by the eccentrics 147 on the shaft ends of the scraper blade bar 144. When the more greatly projecting portions of the eccentrics 147 are on the side frames 148 they hold the scraper blade in operative position and prevent any sagging downwardly or lowering of the roller 140 from the ink-distributing drum 142, but

when the handle 149 is turned downwardly to remove the. scraper'blade 143 from its operative position, the narrow sections of the eccentrics engage the side frames 148 and allow the lowering of the bars 158 and with them the receptacle 141 and roller 140 to a suflicient extent to releasethe roller 140 from the drum 142. The side frames or bars 158 are connected with and in part supported from bars 163 which are pivotally secured at their forward ends to stationary side frames of the press and hence may turn downwardly when permitted so to do, this being when 148 and are on the shaft ends of the scraper bar 144 mounted in the side frames or bars 158, the bars 163 will move upwardly and downwardly under the control of the eccentrics 147, moving upwardly to aid in elevat- 5 ing the receptacle 141 and engaging the roller 140 with the ink distributing drum 142 when the more greatly projecting por-,

tions of the eccentrics are turned to engage the side frames 148 and turning downwardly when said eccentrics are rotated to a reverse position so gravity of the receptacle 141 and roller .140. The bars 163 are connected with the bars or side frames 158, and said bars or side frames 158 are connected with the receptacle 141, uninking roller 14(,), and scraper blade bar 144 and'serve to steady said bars or side frames 158 and receptacle 141 during the upward and downward movements of the same. The upward and downward movements of the receptacle 141 and roller 140 are controlled by the eccentrics 147 which have simultaneous movement with the scraper blade bar 144' under the manual operation of the handle 149. During the upward and downward movements of the receptacle 141 and roller IA-O, the pipe section 154 will flex sufficiently not to require a I separate joint and not to interfere with the vertical movement of the

receptacle

1,41 and parts connected therewith.

The operation of the modified embodiment of our invention shown in Figs. 12 to 18 inclusive will be understood from the foregoing description without further detail explanation. Then the press is to be cleaned the receptacle 141 will be elevated and the roller 140 placed in engagement with the ink-distributing drum 142, and the scraper blade 143 will be engaged with the roller 140. The press may then continue in motion and the ink or color will be drawn over to the roller 140 and removed therefrom by the scraper blade 143. The ink-distributing drum 142 always rotates in the same direc- 147 will turn downwardly to as to permit the lowering by tion, and therefore only one scraper blade 143 becomes necessary.
