To all whom it may concern..-

Be it known that I, EDWARD THOMAS CLEATHERO,of The Hollies,Barrington Road,

Altrincham, in the county of Chester, England, have invented certain new and useful Improvements in and Connected with Machines for Cleaning the Rollers of Printing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in and connected with automatic and preferably power-driven machines for cleaning the inking'rollers of printing-machines, either lithographic or typographic.

The object of it is to provide a machine that can deal with rollers irrespective of the length of the latter, dispense with special devices for holding them in position While they are going through the several stages of the cleaning process, and clean them in part or completely Without injuring their peripheries.

The terms clean, cleaning, cleaned are to be understood as including the three distinct acts of washing the ink off the dirty roller, rinsing the washed roller, and drying the rinsed roller.

The basic feature of the invention is a pair of rollers rotated side by side at difierent speeds, but in the same direction, and so mounted in their bearings that the printingroller canlie in the angular-recess formed by the juxtaposition of the opposite faces of the upper portions of the said pair and the printing-roller will be held in contact with the said portions by its weight. The pair of rollers will rotate the printing-roller and rub its periphery between them.

The invention requires that one or two or all the distinct acts of washing, rinsing, and drying must be performed by one or more pairs of the rollers just described; but it is indiiferent whether the machine contains only one such pair (in whichcase it will be a washing or a rinsing or a drying machine) or whether it contains one, two, or three such pairs. A machinehaving one such pair may also have a single-roller washing or rinsing or drying device or any one or two of them of any well-known kind. i

one roller at a time.

Each of the above-described pairs of rollers or single-roller device is provided with a suitable trough to work in, suitable pipes to supply and draw 0E either or both the liquids used in each, and suitable squeezers applied from either above or below to remove the fouled liquid from the respective pair or device.

A machine comprising two or three of the above-described pairs of rollers 01' a machine comprising one such pair and one or two single-roller devices or two such pairs and one single-roller device has an intermittent feeder to present the printing-rollers one by one to its cleaningorgans in succession. This intermittent feeder is of a rotary type and is either manual or geared with the other rotating organs of the machine. It consists of arms adapted either to'have the printing-rollers temporarilyattached to them during the passage of the former through the machine or to push the said rollers before them over thewashing, rinsing, or drying rollers, as many as there may be, each arm dealing with only The printing-rollers are fed to the carrier manually, a suitable device being provided, if desired, to secure the desired intermittence. The series of pairs of rollers and single-roller devices may be arranged inan arc concentric with the axis of the feed or ina row under the feed. The intermittence just mentioned extends also to the travel of the printing-rollers through the machine, each roller being temporarily held or left in contact for a proper time with the respective pair or device. Referring to the accompanying drawings,

Figures 1 and 2' together constitute a front elevation, partly insection, of a power-driven machine for either washing or-rinsing or drying one printing-machine roller at a time. Fig. 3' is an end elevation from the left hand of Fig. 1; Fig. 4, a plan corresponding with Figs- 1 and 2; Fig. 5, a front elevation, partly in section, of a power-driven machine for washing and drying printingrollers and which comprises a manual and intermittent feed for successively presenting theprinti-ngrollers to the pair of washing-rollers and the single-roller-drying device; Fig. 6, a side elevation from the left hand of Fig. 5; Fig. 7, a vertical section on the line 77 of Fig. 5; Fig.

8, a side elevation of the washing and dryingrollers and the'intermittent feed from the left hand of Fig. 5'; Fig. 9, a side elevation of a power-driven machine comprising washing, rinsing, and drying rollers and which comprises an automatic and intermittent feed for successively presenting the printing-rollers to the washing pair; Fig. 10, a plan corresponding with Fig. 9, but omitting the rollers to be cleaned and those that have been cleaned; and Fig. 11, an end elevation of Fig. 9 from the right hand, but without the rollers that have been cleaned.

Referring to Figs. 1 to 4, a pair of standards 1 2, held together by a pair of tie-rods 3 3, and a bracket 4, bolted to the standard 1, constitute the frame of the machine. 5 is the, shaft that carries the fast and loose pulleys 6 7. It turns in bearings 8 9 in the bracket 4 and standard 1. 10 is the trough, supported at the proper height between the standards 1 and 2. 11 is the pipe to carry away the fouled liquid from the said trough, and 12 its controlling-cock. None of the parts just described are features of the present invention and may for that reason be of any suitable construction.

13 14 are the pair of equal and parallel rollers, and 15 16 their shafts,turning in bearings 17 17 in the tops of the respective standards 1 and 2, the axes of the rollers being preferably in the same horizontal plane. These shafts are prolonged through the standard 1, each prolongation having fast on it outside the standard a spur-wheel which do not gear directly with each other, because the rollers 13 14 are required to rotate at difierent speeds. The spur-wheel18 on the roller-shaft 15 is smaller than that, 19, on the roller-shaft 16; but they are of the same pitch. The required difference in the rate of rotation is secured by driving them both directly by a third wheel 20,fast on the pulley-shaft 5. This direct driving is illustrated by the dotted lines in Fig. 3 and also provides that the two

rollers

13 and 14 rotate in the same direction, as indicated by the arrowin Fig. 4. The rollers 13 14 are of the same diameter and are of any material suitable for their particular purpose. The printing-roller lies in the angular space formed by the opposite faces of the upper portions of these rollers. A printing-roller 21 is shown in dot-and-dash line in this recess.

22 is a squeezer to squeeze liquid out of the rollers 13 14. It consists of a loose rinsingroller (which may be of any suitable material) of the same length as the pair of rollers '13 14, its ends turning in bearings 23 24, in-

corporated with brackets 25 26, fitted with set-screws 27 28, adapted to pull the squeezer into proper contact with the opposite faces of the lower portions of the rollers 13 14 by hearing down upon the ends of the trough 10, as shown best in Figs. 1, 2, and 4.

29 30 are set-screws the shanks of which are passed through vertical slots 31 32 in the standards 1 2 into the respective brackets 25 26 to hold them in position after that of the squeezer has been adjusted by the

screws

27 and 28.

The periphery of a used printing-roller is frequently so uneven that a pair of parallel rollers, such as 13 14, when used as washingrollers cannot come into contact with the low parts of it. To meet such a case, one end bearing (see Fig. 4) of one roller of the pair is movable away from its fellow bearing, whereby any desired zone in the length of the printing-roller may be subjected to extra pressure and rubbing, according to the width between the two end bearings, one of which shall have been moved away from its fellow for that pu rpose. The movable bearing 17 can slide upon the standard 2 between that top and the cap-plate 33, being held in any given position with reference to its fellow bearing on the same standard 2 by a spring 34, resilient in a cavity 35 between the bearing and the op posite face of the cavity, and a set-screw 36, turnable in the same standard or in a lug 37, fast thereto on the opposite side of the hearing 17*, bya hand-disk 38. Thus if the setscrew is turned outward the spring 34 moves the bearing 17 away from its fellow bearing, and when it is turned inward again more or less, as may be desired, the bearing 17 is moved back again.

39 is a fixed core to prevent the spring 34 buckling.

The

rollers

13 and 14 are both shown as parallel throughout their length. Either or both may be, if desired, slightly barreled-i. e.,

larger in the middle-the diameter gradually decreasing toward each end.

Referring to Figs. 5 to 8, a pair of standards 40 41, held together by tie-rods 42, and a bracket 43, bolted to the standard 40, constitute the frame of the machine. 44 is the shaft that carries the fast and loose pulleys 45 56. It turns in bearings 47 48 in the bracket 43 and standard 40. 49 is the washing-trough, supported at a proper height between the

standards

40 and 41 by flanges 5O 51,projecting from its respective ends and resting upon and screwed to ledges 52 53, projecting inwardly from the standards-40 41, respectively. 54 is the pipe to carry away the fouled liquid from the

trough

49, and 55 is its controllingcock. None of these parts 40 to 55 are features of the present invention, and for that reason they may be of any suitable construction.

56 and 57 are the pair of washing-rollers. They are made of any material suitable for their purpose. Like the

pair

13 and 14 of Figs. 1 to 3 they are parallel, of the same length and diameter, and rotate in the same direction, but at different speeds. They are driven from the shaft 44 by a pinion 58, fast thereon and gearing with a spur-wheel 59, turning in a bearing 60 on the standard 40. This wheel 59 gears with the two spur-

wheels

61 and 62 of the same pitch, but of different diameters. Each of these is fast on its respective spindle 6.3, each spindle turning in a bearing 74 in the standard 40. The inner end of each spindle 63 is a socket 105, which receives the tapered end of the respective shafts 64 65 of each roller 56 57 of the washing pair, and a flat 66, in which the said end terminates, as shown in the dotted lines in Fig. 5. Theopposite end of each shaft 64 65 turns in a respective bearing 67 in the ing-

wheels

61 and 62.

. 69 is a squeezer to squeeze fouled liquid out of the pair of washing-rollers 56 57. It is shown as consisting of a roller (which may be of any suitable material) of the same length as the rollers 56 57, its ends turning in bearings 71, incorporate with brackets 72 73. These brackets have combined with them set-screws 27 28 29 30 and slots 31 32 in the same way and for thesame purpose as described with reference to Figs. 1 to 3.

One of the two bearings 67 of the shafts 64 65 may be adjustable to and from its fellow for the same purpose and by means of the same adjusting devices as described with reference to the bearing 17 of Figs. 1 to 3.

Likewise either or both the rollers 56 57 may, if desired, be slightly bellied in the middle.

is a drying device ofa well-known construction. It is shown as consisting of a single roller mounted on a shaft 76, which is rotated in bearings 77 78 on the respective standards 40 41 by a gear-wheel 79, driven by the wheel 59, already described, and driving a wheel 80 on the shaft 76.

81is a squeezer to squeeze fouled liquid on of the roller 75. .It is shown as consisting of a roller (which may be ofany suitable mate-. rial) mounted on a shaft 82, turning in bearings 83 84, which are adapted to slide in ver tical guides 85 86 on the

respective standards

40 and 41. The squeezer 81 is put into and out of working contact with the dryingroller 75 by means of an inverted set-screw 87, working in a lug 88 on the inner face of each of the

standards

40 and 41 and engaging the under side of the respective bearing for that purpose.

89 is a removable drip-plate hanging from the top tie-rod 42 behind the drying device.

It is bent to the front underthe latter and holding the cleaned rollers to be taken out of the machine is illustrated in Figs. 4 to 7 and consists of two x-shaped plates 90 91; four/ties 02 92,.ho1dingthese two plates para allel with each other and at the proper distance apart; an axle93, on which the two plates 90 91, duly tied together, are mounted and which turns in hearings in the frontends of two levers 94 95, having their respective fulcra 96 97 in the standards 40 41; a pair of S-hooks 98 98, hanging from each of the four tie-rods 92 to receive and carry a printingroller 99 through the machine; a square 100 on the outside of the X-plate 90 and having its four corners radially coincident with the arms of the X-plates 90 91; a notched bracket 101, fast to the inner face of the respective standard 40 to receive the bottom corner of the square 100; a treadle 102 at the front of themachine, pivoted on the rod 103 at the rear and linked by the pair of links 104 104 to the rear ends of the levers 94 95. It is used as follows: So long as the attendant does not depress the treadle 102 the. weight ofthe roller-feed keeps itlocked against rotation by holding the bottom corner of the square 100 in the notched bracket 101. Such an engagement of square 100 and bracket 101 presents one pair of books 98 in each of four. equidistant positionsviz., one pair to the 1 attendant, one pair to the pair of washingrollers, one pair to the drying-roller, and a fourth pair outside the machine ready for the attendant to take the washed and dried roller off. Accordingly he puts a roller 99 into the pair of hooks 98 98 hanging before him, depresses the treadle to unlock the axle 93,

turns the feed through quarter of a circle,

IOO

andv releases the treadle 102, thereby making the feed present the first roller to the washing-

rollers

56 and 57 and hold it in contact with the upper portions of each until 'it has been Washed. He then hangs'anothei' printing-machine roller in the pair of hooks 98 98 l at that moment in front of him, depresses the treadle 102, turns the feed through a secondquarter of acircle,and releases the treadle, as before, thereby making the feed present the first printing-roller to the drying-roller succession, the pair to which the printingrollers are first presented being the washing pair, the second the rinsing pair, and the third the drying pair. 105 106 are a pair of side frames held together by ties 107. 108 is the (lrivingbelt, passed around the pulley 109 and driven by any suitable means in the di rection indicated by the arrows in Fig. 9. This pulley 109 and a gear 110 are fast on the shaft 111, turning in suitable bearings carried by the side frame 105. 112 113 are the pair of. washingrollers and 114 their squeezer.

115 116 are the pair of rinsing-rollersandl17 l ing-rollers and their squeezer.

their squeezer. 118 119 are the pair of dry- 121 is a trough divided by two transverse partitions 122 123 into the washing-trough 124, in which work the washing-rollers 112 and 113 and their squeezer114, the rinsing-trough 125, in which work the rinsing-rollers 115 116 and their squeezer 117, and the drying-trough 126, in which work the drying-rollers 118 119 and their squeezer 120. The trough 121 is held in working position by any suitable means, such as by a flange 127 128 at each end, resting upon the ledges 129 130, respectively, to which they are bolted. 131 132 133 are drawoff pipes from the respective troughs 124,125 126.

The three pairs of rollers and squeezers just described are rotated from the gear 110. To rotate the rollers 115 116 and the squeezer 117, the gear 110 meshes with a pinion 134, fast on the shaft 135 of the roller 115. This pinion 134 meshes with a pinion 136, suitably mounted on the side frame 105 and which in turn meshes with a pinion 138, fast on the shaft 139 of the roller 116. The difference in speed of the two rollers 115 116 is secured by differences in the diameters of their respective pinions. Either of the two may be the larger. In the figures, 134 has eleven and 138 twelve teeth. To rotate the rollers 112 113 and the squeezer 114, the pinion 134 meshes with one, 140, suitably mounted on the side frame 105, and which in turn meshes with one,

- 141, fast on the shaft 142 of the roller 113.

, This pinion 141 meshes with one,143,on aspindle 144, suitably mounted in the side frame 105, and the pinion 143 with one, 145, fast on the shaft-146 of the roller 112. The relationship as to diameter between the pinions 141 and is the same as between the pinions 134 and 138 before described and for a like reason. To rotate the rollers 118 119 and the squeezer 120, the pinion 138 meshes with one, 147, suitably mounted on the side frame 105, and which in turn meshes with one, 148, fast on the shaft 149 of the roller 118. This pinion 148 meshes with one, 150, fast on a spindle 151, turning in a suitable bearing in the side frame 105, while the pinion 150 drives the other roller 119 of the pair by meshing with a pinion 152, fast on the shaft 153 of the said roller. There is the same relationship as to diameter between the

pinions

148 and 152 as there is between the pinions 134 and 138 or between 141 and 145 and for a like reason.

It will be noticed that the combination of pair of rollers, squeezer, and the respective trough just described is practically the same as that illustrated in Figs. 1 to 4 and described therewith; but the squeezer 22 is vertically adjustable, while the

squeezers

114, 117, and 120 are not so shown. It is to be understood, however, that the present invention includes the combination with the pair of rollers described of a loose-running rollersqueezervertically adjustable or not, as may be preferred.

table.

The construction illustrated in Figs. 9 to 11 furtherincludes a device which is applicable to any machine according to the present invention irrespective of the number of pairs of the rollers above described, with which it may be fitted. The object of the said device is to impart areciprocating movement to one roller of each pair, (but only in the case of parallel r0llers,) excepting the last pair in the direction of its axis for the purpose of increasing the rubbing effect between the so reciprocated roller and the printing-machine roller on the one hand and the squeezer on the other. The said object is attained by the following means: 154 is a pinion fast on the shaft 111 and meshing with a gear 155, fast on a spindle 156, turning in a suitable bearing in the side frame 105 and having fast on its opposite end a pinion 157, which meshes with a gear 158, fast on the adjacent end of a shaft 159, turning in suitable bearingsin the two side frames 105 106. The end of the shaft 159 is prolonged past the side frame 106, where its end terminates in a pin 160, which is eccentric to the said shaft. 161 is a connecting-rod from the pin to an arm 162, fast upon a shaft 163, turning in bearings formed in bracket pieces 164 on the side frame 106. Each roller to be reciprocated has its shaft prolonged past the side frame 106, and the shaft 163 carries a respective and upstanding arm 165, the top end of which engages loosely with the prolonged shaft end 6. g., by means of a fork 166 engaging between a pair of collars 167 168.

The intermittent feeder illustrated in Figs. 9 to 11 has all the functions of the one illustrated in Figs. 5 and 8 that are essential to the invention and is in addition thereto, it is automatic throughout being driven by the machine, feeds itself with a dirty printingmachine roller and itself delivers the cleaned one. 169 is a table carried by ledges 170 170 on the side frames 105 106. It is declined in the direction of the washing-rollers 112 113, and the dirty rollers 171, as they lay lengthwise upon it, roll down it until they are stopped by the detent-roller 172. 173 173 are grooves in its periphery. They are arcual and less than a semicircle in cross-section, extend from one end of the roller 172 to the other, and are symmetrically arranged about the same, each one being intended to receive the leading dirty roller 171 from the table 169 and to allow the said roller to roll out of it away from the said 174 is a ratchet-wheel fast on the shaft 175 of the roller'172, this shaft turning loosely in hearings in the side frames 105 106. The ratchet-wheel 174 has as many teeth as the detent-roller 172 has grooves 173, each ratchet-tooth having a definite relationship to the respective groove. 176 is a gravitypawl pivoted upon the side frame 105 to cooperate with the ratchet-wheel 174, and the angular position of the latter with reference to the roller 172 is such that when a tooth of the ratchet-wheel 174 is engaged by the pawl 176 the bottom of the respective groove 173 has just passed the vertical plane which passes through the axis of the roller 172.

177 is an upward extension of that side of the lwith reference to the roller 172.

. turning on a spindle 187, fast to the side washing-trough 124 next to the roller 172, its top forming part of the path which the leading inked roller takes on its way from the.

table 169 down to the washing-rollers 112 113. 178, 179, and 180 are three rods parallel with each other and with the three pairs of rollers 112 113, 115 116, and 118 119. Each is carried by a pair of arms 181 182, fast to one of three transverse shafts 183 184,

r'turning in suitable hearings in the side meshes with the wheel 185, fast on the shaft 184, and the wheel 185 with a pinion 186,

frame 105, which meshes with a gear 188, fast on the shaft 183, the

gears

185 and 188 being of the same size as the one 158. 189 and 190 are upstanding extensionsof the partitions 122 123 and form part of the path of a printihg-machine roller through the machine. 191 is a, roller delivery table onto which the feeder delivers the cleaned rollers and down and over which the leading roller rolls as far as a stop 192, fast along the outer edge of the table 191. 193 193 are ledgesfast on the inside faces of the side frames 105 106 to support the table 191. I

The carrier just described acts as follows:

-The printing-machine rollers to be cleaned having been laid upon the table 169 one behind another roll down it until they are stopped by the contact of the leading one with the detent-roller 172, then standing in the position illustrated and seen best in Fig.

9. One such roller is laid in the top groove 173 of the said detent-roller 172 and the machine started. The revolving rod 178 trips the pawl 176, whereupon the weight of the roller in the top groove 173 turns the detentroller 172 far enough to allow thesaidroller to roll out of the groove in questionand over the extension 177 and washing-roller 112 into the angular space between it and the washing-roller113, as shown in Fig. 9. The partial rotation of the detent roller. 172 that sufficed for the escape of the printingmachine roller from the top groove 173 brings the next groove up opposite to the leading one of the dirty rollers 171 on the table 169 and which accordingly rolls into it. The continued rotation of the roller 172 brings the last-mentioned groove and roller in it up to the top, where it is locked by the engagement of the respective tooth of the ratchetwheel 174 with the pawl 176, the rod 178 having already cleared the said pawl, (and passed the washing-rollers 112 1133, too,) so that it has returned to its normal position before the said tooth has come to the top. It is to be borne in mind that the above-mentioned partial rotation of the detent-roller 172 is effected by the weight of the printing-machine iroller in the top groove 173. By thetime the rod 178 comes up behind the printing- Imachine roller now on the washing-rollers 112 113, the latter having completed the washing of it, and the rod 178 rolls it forward over the extension 189 onto the rinsing-rollers 115 116, therod 179 being at that time out of the path of the roller. By the time the latter is rinsed the rod 179 comes up behind itand rolls it forward over the extension 190 onto the drying-rollers 118 119, the rod 180 being at the time likewise out of the path of the roller. By the time the latter is dried the rod 180 comes up behind it and rolls it over the drying-roller 119 onto the table 191.

I claim- 1. The combination of a pair of rollers rotated in the same direction but at difierent speeds; a single-roller device; and means for rotating the said pair of rollers and the single-roller device.

2. The combination of a multiplicity of pairs of rollers, the rollers of each pair rotated in the same direction but at difierent speeds; a single-roller device; and means for rotating the said pairs of rollers and the single-roller device.

3. The combination of a multiplicity of pairs of rollers, the rollers of each pair rotated in the same direction but at difierent speeds; a multiplicityof single-rollerdevices; andmeans for rotating the said pairs of rollers and s'ingle-rollerdevices.

4. The combination of one or more pairs of rollers, the rollers of each pair rotated in the same direction but at different speeds; a trough for each pair of rollers to work in; a single-roller device; a trough for it to work in; and means for rotating the said rollers and single-roller device.

5. The combination of one or more pairs o rollers, the rollers of each pair rotated in the same direction but at different speeds; a

trough for each pair of rollers to work in; one or more single-roller devices; a trough for each single roller device to work in; and means for rotating the said rollers and singleroller devices.

6. The combination of one or more pairs of rollers, the rollers of each pair rotated in the same direction but at different speeds; a

gle-roller device, means for rotating the said pairs of rollers and single-roller device; and an intermittent rotating feeder having its axis parallel with those of the said pairs of rollers and single-roller device, adapted to receive the printing machine rollers to be cleaned and to present them one by one to the respective pair of rollers and the singleroller device in succession.

8. The combination of one or more pairs of rollers, the rollers of each pair rotated in the same direction but at different speeds; one or more single-roller devices; and an intermittent rotating feeder having its axis parallel with those of the said pairs of rollers and single-roller devices, adapted to receive the printing-machine rollers to be cleaned and to present them one by one to the respective pair of rollers and single-roller device in succession.

9. The combination of two rollers parallel with each other and having their axes in the same horizontal plane; means for rotating them in the same direction but at dilferent speeds; a trough for the said rollers to work in; a vertically-adj ustable roller adapted by having its periphery in contact with the lower faces of both the rollers of the said pair, to serve as a sqneezer; and a draw-01f pipe from the trough.

10. The combination of two rollers parallel with each other and having their axes in the same horizontal plane; means for rotating them in the same direction but at different speeds; a trough for the said rollers to work in; a roller adapted by having its periphery in contact with the lower faces of both the rollers of the said pair, to serve as a squeezer and a draw-off pipe from the trough.

11. The combination of two rollers parallel with each other and having their axes in the same horizontal plane; means for rotating them in the same direction but at different speeds and a loose running roller adapted by having its periphery in contact with both the said rollers to serve as a squeezer.

12. The combination of two rollers parallel with each other and having their axes in the same plane; means for rotating them at different speeds but in the same direction; and means for imparting a reciprocating movement to one of the said rollers in the direction of its axis.

13. In a machine for washing or rinsing or drying the rollers of a printing-machine, the combination with the means for washing or rinsing or drying or with any one or two of them, of an intermittent rotating feeder having its axis parallel with that of the machine roller or rollers and adapted to receive the dirty rollers one by one and to traverse them through the machine.

14.. In a machine for washing or rinsing or drying the rollers of a printing-machine, the combination with the means for washing or rinsing or drying or with any one or two of them, of an intermittent feeder comprising a declined table to receive the inked rollers; a grooved detent-roller to receive one inked roller at a time and to stop the motion of the others down the table; a pawl-and-ratchet device to control the rotation of the detentroller; a rotating rod cooperating with each washing, rinsing or drying means to move the prin ting-machine rollers successively through the machine; means for working the same; and a table to receive the printing-machine rollers.

15. In a machine for washing or rinsing or drying the rollers of a printing-machine, the combination with the means for washing or rinsing or drying or with any one or two of them, of an intermittent feeder comprising a declined table to receive the inked rollers; a grooved detent-roller to receive one inked roller at a time, to be turned about its axis by the weight of that inked roller, and to stop the motion of the others down the table; a pa wl-and-ratchet device to control the rotation of the detent-roller; a rotating rod cooperating with each washing, rinsing or dry; ing means to move the printing-machine rollers successively through the machine; means for working the same and a table to receive the printing-machine rollers.
