To all whom it may concern.

Be it known that l, anner L. Gal-tux, a citizen of the United States. residing in the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Printin -Machines, of which the following is a specification, reference being had therein to the accompanying drawings. which form a part thereof.

My invention relates to printing machines and more particularly to a type thereof adapted for under-surface printing or printing from intaglio plates.

The main object of the invention is to provide a printing machine which will be capable of printing from intaglio or engraved plates on a continuous web of paper and by a substantially continuous o oration, without lowering the quality of tie work, thus insuring a machine of large capacity.

A. further object is to provide a printing machine employing a plate or form cylinder and a wiping and polishing mechanism in connection tlierewith consisting of a continuously changing absorbent material whereby all the ink deposited on the surface of the plate or plates, as distinguished from that in the depressions, will be removed and the said surface will be wiped and polished with each rotation of the cylinder and prior to the taking of each impression or imprint therefrom.

A still further object to provide a wiping and polishing mechanism whereby a fresh section of an absorbent wiping and polishing strip will be automatically fed relative to the form cylinder during each rotation thereof, thus avoiding the necessity for the use of successive wiping and polishing means. and those delays incidental to the removal and substitution of wipers and polishers as such become soiled through con tinued use to an extent to fail to properly clean and polish the surface of the plate or plates.

A still further object is to provide a wi ing and )olishing mechanism wherein t e wiper wil have during the rotation of the form cylinder, movement opposite to the direction of the peripheral travel of said cylinder and a simultaneous lateral movement. to insure the utilization of a erfectly clean wiper for the final polishing, and to avoid any tendency of the texture of the wiper causing a streaking of the surface of the plate or plates.

A still further object is to provide a wi ing and polishing mechanism which will capable of such adjustment and regulation as to permit the wiper to be so tensioned with relation to the form cylinder as to insure that pressure required to properly wipe and polish the plate or plates.

A still further object. is to provide a wiping and polishing mechanism capable of using a continuous strip of rd ing and polishing cloth and of so rewimling the same after it has passed throu h the machine as to permit it to be use a second time with the reverse side next the plate or plates.

A still further object is to provide a wi ing and olisliing mechanism wherein tlie cloth wil be relieved in great part from the strains incidental to feeding it. through the machine.

A still further object is to provide a flexible backing for the Wl)ll1 and polishing cloth so arranged as to aci itate the threading of the cloth through the machine.

A still further object is to provide a machine of this character wherein the D-roll or platen c *linder, will be so driven relative to the p ate or form cylinder as to cause it to accurately register with the plate or plates with each successive rotation of the form cylinder.

A still further object is to rovide in a machine of this character, a -roll which, while adapted to be driven through frictional engagement with the )late or plates, will be brought to rest at t e end 0 each rotation in a manner to avoid its overrunning the position necessary to secure a perfect registering thereof with the plate or plates upon the next rotation, and will be capable of being positively started in such synchronism with the movement of the form cylinder or plates, as to insure such registering with each rotation.

A still further object is to provide, in such a machine, means whereby the D-roll or platen cylinder may be thrown in and out of gear as desired in running the machine.

A still further object is to provide in such a machine, means whereby, when the D-roll is out of gear, said roll will be held against any movement through friction between any partof said roll and moving parts of the mechanism adapted to rotate same.

A. still further object is to provide a machine wherein any slack in the blanket will be immediately taken up, thus avoiding such looseuess or wrinkling of the blanket as would interfere with the frictional drive of the D-roll from the form or plate cylinder; the quality of the imprint, or the continued registering of the D-roll with the plate or plates.

A still further object is to provide a machine wherein the opposite bearings for the shaft carryin the D-roll, ma be minutely adjusted simultaneously, radia y of the form or late cylinder.

still further object is to provide a machine with a web re-winding mechanism which will automatically adjust its speed of rotation with each increase of the diameter of the roll thereon, thus permitting the paper web to be run throi h the machine and to be re-wound after receiving the imprint.

A still further objectis to so arrange the re-winding mechanism that a continuous web of tissue or other thin )aper or material may be woimd with the we in a manner to prevent the smudging of the work.

A still further object is to provide a machine wherein the paper may be fed directly to the machine withouthavin previously been dampened, thus avoidi t e shrinka 'e of the paper, the removal of t e sizing of the paper, and the labor and ex ense incidental to such dampening and $110 refinishing or recalendering of the paper.

A still further object is to provide a machine with a damping mechanism which will 0 crate continuously during the feeding of t e paper, to transfer an even, thin film of liquid to the surface of the paper in a manner to cause the paper to readily take up the ilik from the intaglio or under cuts of the p ate.

A still further object is to provide in such a mechanism a main reservoir and an auxiliary reservoir for the liquid, and a pipe connection between the two whereby the liquid will be supplied to the latter from the former in quantities to maintain a substantially constant level therein, and means whereby said supply will be automatically cut oil during intervals when the D-roll is out of gear and the paper is notbeing fed relative thereto.

A. still further objectis to provide a machine of this character wherein the plate or plates will be automatically wiped and pollshed and the pa. er will be dampened Just prior to being fed thereto and whlle passing through the machine.

A still further object is to provide a machine of this character wherein the printed web will be fed from the form or plate cylinder in a manner to avoid any likelihood of the fresh ink being smeared.

A still further ObJGCt is to provide in such a machine, means whereby the printed web will he sub'cctell In such heat as will rapidlv dry the hill and remove the moisture from the paper by heat drying, without injury to the paper itself. And a still further ohp-ct is t provide a machine wherein the inking, wiping and polishing of the plate or plates. and the feeding of a continuous web of paper and the dampin thereof. will be done in such sequence aucf in such svnchronism with relation to each other as to permit the machine to be operated substantially automatically and coutinuouslv.

The invention consists in the novel features of construction and combination of parts hereinafter set forth and described and more particularly pointed out in the claims hereto appended.

Inthc embodiment of my invention shown in the drawings, I have shown at '21 the frame designed more particularly for the printing mechanism, and at 22 aframe for the wiping and polishing cloth roll and the paper web mechanism, together with the rewiiliding mechanisms for the cloth and the we i.

Mounted in the frame 21 is the main power shaft 23 which may be driven from an desired source of power, a pulley '24 bem shown.

ll ounted above the main power shaft 23 is the form or plate cylinder 25 which is driven by a shaft 26 having mounted thereon the last of a chain of gears 27 driven from the shaft 23.

Qarried by the frame 2t adjacent to the cylinder 25, is an ink fountain and feeding and spreadin roll mechanism 28, the de tails of whic being immaterial to the in vention will not be described. Any desired type of inking mechanism may be employed. This mechanism is driven by a gear carried by the shaft :26.

A shaft 29 is mounted in the frame 2i adjacent to the shaft- 26 from which it is driven by a chain and s rocket mechanism 30. This last mentionet shaft. has keyed or otherwise secured thereon, a bevel gear 31 "and one member of a clutch 3:2, and has loosely mounted thereon a sprocket wheel 33, carrying the other inelnbcnfll, of the said clutch, thus permitting said sprocket wheel 33 to remain idle or to be caused to rotate with the said shaft. This construction is provided for the purpose of permittiug the wiper feed mechanism to be thrown in and out of gear at. will.

In presses of this character. it is necessarv to ink the plate or plates, to wipe the in from the upper surface thereof leaving the iutaglio de ign or under surface filled with ink. and thereafter to polish the upper surface so as to avoid streaking or s ottnig of the imprint taken therefrom. arious means have been )10\'l(18d to perform these operations. in di erent types of machines,

varying from the machine wherein both are done by hand. to those wherein the wiping done by hand. and those wherein each plate is subjected to the action of first one set of cloths for wi ing and then a second set of cloths for pc ishing. In the present machine, however. I have embodied these steps in practically e si leoperation, ra g from wiping to polishing, with regal to the diiferent positions of the parts during each rotation of the plate or form cylinder. In addition to this, I so construct and arrangethe wiper feed mechanism that any likelihood of the plates being streaked 1S obviated. This mechanism comprises two rollers 35 and 36 mounted in hearings or frames 3T38 respectively on opposite sides of the form or plate cylinder 2."), and in close juxtaposition thereto. The frames 37 and 38 are seated in ways in the frame 2-1 and are ca able of lateral movement which is. impart thereto simultaneously with the actuation of the wiper feed mechanism. This lateral reciprocation is imparted to the frame 38 by means of a stra 43 within which'is an eccentric 44 mount. on a shaft 45. which is driven from the said gear 31 I through a bevel gear-.46. The shaft seated in thebearings 37 is reciprocated bymeans amtlnn- 39 carried thereby and acted upon b anecceutric 40 carried on the shaft 41." T e rollers 35 and 36 are irllers. The

.fraliline m has mounted therein two parallel "47} and '48 of resilient material, prefbly ti-itub alj r s do b v t m other in bearings which are adjustable toward and from each other to regulate the pressure of these rollers upon each other. Said rollers are driven at equal velocity by iutermcshing gears on the shafts thereof. a sprocket wheel -19 carried by one of said shafts. and a chain 50 meshing therewith and with the sprocket wheel 33. On the other end of the frame 2i :1re the wiper cloth guide rollers 51 and 52. To eflectii'ely wipe and polish the plates, it is nec- (:SSRIZV to place t :e cloth under such tension as to always hold it perfectly taut, thus causing it to press hard u Jon the plates. As the said cloth, which in t to drawings is indicated at 53, is drawn from a point beyond the plate or form cylinder, such tensioning must be accomplished by a resistance a L plied thereto on the forward side of said cylinder, each side being determined with relation to the direction of feed of the cloth. This tensionin means preferably comprises a metallic roller M having a plurality of knurled circmnferential ridge-i thereon, as 55, adapted and designed to afi'ord the requisite gripping area. and carrying a brake drum 56. The said roller bears upon the roller 35 and is driven by its frictional engamement therewith. It. is secured to its shafi by means of a feather, thus being permitted to have lateral movement with the roller 35. The bearings for the rollers and 54 are themselves incapable of lateral movement. but are adjustable relativeto each other by means of the adjustment screw 35', to regulate the pressure of the roller on the roller 35, overn'ing the slip age of the cloth and its backing. in fe ing between said rollers; and both said beatings are adjustable toward and from the form or plate cvlinder by means of the racks 54 carried by the bearingspf the roller 54. and the pmions 54" in mesh with each said rack, in order to permit the regulation of the quantity of surace of the wiper cloth contacting with the plate or plates on said cylinder. The pinions 54" are carried on a shaft 54 having a worm wheel 54 actuated by a worm 54". thus adjusting the said rollers 54-35 by a simultaneous equal movement of both ends thereof. The rotation of the roller 54 is take up roller 62.

To relieve the cloth 53 as much as possible from the strains thereon, I provide a strong backing therefor comprising an endless belt; 63 running about the rollers 35, 36, 47, 48, 5t. 62, and 5-1, which belt is made of strong reinforced material, and takes up enough of the strain to permit the use of a wiping cloth of the desired teature. To facilitate the threading of the wiping cloth through the machine, I provide said belt with a flap til under which the end of the continuous strip of cloth may be inserted.

In the lower part of the frame 21, 1s a guide roller 65 for the wiper cloth, to facilitate the feeding and rewinding thereof. The frame 2:2, carries similar rollers 66, 67 and 68, and also a removable roller 69 for the roll of cloth. If desired polished rods may be substituted for the various rollers above referred to.

The wiper being in the form of a continuens web and having a substantially continuous feeding movement, it is desirable to rovide means whereby it will be re-woun to mnveniently store same after use, and also to permit it. to be run through the machine a second time with the reverse side operative. It is also necessary to provide a rewinding mechanism, the velocity of which will be automatically controlled to conform to the variance in the diameter of the roll of cloth on the spindleat any time. This last mentioned mechanism preferably cornprises a shaft 70 mounted in the frame 22 carrying one member of a friction clutch 71 thereon, and having loosely mounted thereon a sprocket wheel 72 carrying the other member of said clutch. The said sprocket wheel is driven from the shaft 23 by means of a sprocket wheel T3 thereon, and a chain 7' The wiper strip when wound on the s indie or shaft 70 with the dirty side outwar may be fed therefrom without changing the position of the parts, it being merely necessary to release the clutch 71 so as to allow the shaft 70 to run as an idler, said clutch being set through the nut 75 to permit such adjustment of the machine and the regulation of the friction clutch itself. After running the cloth through the machine the second time, I wind it upon a shaft 76 mounted on the frame 21 and driven through the for convenience in running t V member T7 of a friction clutch carried thereby, a sprocket wheel 78 can ing the other member of said clutch a sproc etchain 79 and a sprocket wheel 80 carried by the main, driving or power shaft 23. v I arrange the shafts 70 and ,76 in the positions shown the machine, hut'suc-h may be difi'eren positioned if desired.

'- Mounted on a shaft; 81 above the form I cylinder and parallel therewith, is the D- 82 carrying a suitably backed blanket 83, The said roll is driven mainly through frictional engagement thereof with the plate or plates on said cylinder; and to regulate the pressure necessary to develop the reguired pressure, I mount the said shaft 81 in bearings 84 housed in openings in the frame 21 each supported by a plurality of springs 85. Acting on said bearings respectively, are screws 86 mounted in said frame, each of which carries a Worm wheel 87 actuated through a worm 88, the shank of which carries a handle as 89 whereby the said bearings may be simultaneouslv raised or lowered to legulate such pressure. in under-surface printin such ressure, to secure a high class of worii, must e minutel regulated, and by the worm, worm whee and screw construction described, the quantity of movement of the bearings max be regulated to the thousandth of an inch, coustltuting a micrometer adjustment. The simultaneous adjustment of both bearings is desirable in that after the machine is time set up, the subsequent adjustment to compcnsate for a variance in the thickness of the blanket through stretching, or of the backing through substitution or wear, may be accomplished without destroying the parallelism of the plate or form cylinder and the D-roll, thus insuring accuracy and speed of adjustment. The blanket is secured to the D-roll by having one end thereof clamped to the forward edge of a recess in said roll, bv means of a clamp 90 and-the other edge by means of a roller 91 having a plurality of alined teeth 92 and a ratchet wheel 93 engaged by a pawl 94 mounted on the end plate of said roll. The blanket is stretched about the D-roll and the backing between itand said roll, until it is perfectly smooth, by taming the roller 91, the pawl and ratchet holding all that is taken up. It is essential that the blanket be kept taut and as ordinarily in use the blanket is liable to stretch and wrinkle, in a manner to spoil the work unless the machine is stopped and the slack taken up, I provide an automatically operated mechanism which will take up any slack with each rotation of the D- roll, thus preventing the development. of material slack and avoiding the necessity for frequent stoppage of the machine, and hence increasing its capacity to that extent, and permittin the use of a continuous aper web wit iout loss through imperfect imprints or the breaking of the web. This mechanism comprises a lever 95 pivoted to the head of the D-roll and normally projected outwardly until checked by the stop pin 96, by a spring 97. The outer face of this lever has an outwardly presented abutment 98 projected beyond the periphery of said roll head. Mounted adjacent; to the D-roll and projecting into the path of the lever 95 is a disk 99 having a resilient rim 100 adapted to engage the abutment 98.

This rim is fairly still, being capable of depression only when the blanket is sufficiently tense. The degree of resilience of the dish determines the tension of the blanket, and should be such as to not subject said blanket, to breaking strains. T he lever 9.3 has pi voted to its free end a spring PI'BSSflLl pawl 101 adapted to engage the teeth of the ratchet wheel 93 at a point to rotate same each time the lever is depressed.

The D-roll is normally driven through its frictional engagementwith the )late or form cylinder. In a machine of t is character wherein high grade work is done, it is essential, to secure speed, that the D-roll and form cylinder should always register so as to bring the recess in the former to the roper position relative to the plates or orms. 0 drive the D-roll and form cylinders by intermeshing gears carried thereby, has been found unsatisfactory in practice as not securing the necessary de cc of accuracy, and consequently a frictional drive of the former is reasonably requisite. Owing to slight variance in the diameters of the D- roll through a stretching of the blanket, and a tendency of the stud roll to over run slightly as itceascs to e: cage the form or plate at its recessed point, rovide starting means whereby the said r0 will receive a positive starting impulse at the ropcr interval relative to the rotation of the plate or form cylinder, and other means svnchronizcd therewith, whereby the said roll will be locked against movement subsequent to or simultaneously with said discn 'agement, thus iuslu'in an accurate registering of the D-roll with 518 plate or platcs .u the initiation of each rotation, and preventing such an over run of the said roll as would interferc with securing such. I also provide means whereby both such means may be thrown out of gear, and a permanent lock set so as to maintain said D-roll stationcry when it is desired to stop the printing tom orarily for any purpose, as ruunin in paper. or changing the wiper cloth. In the drawings, I have shown this mechanism in a form which I have found preferable to accomplish such results, and shall now describe same.

Loosely mounted on the shaft 81 is a gear 102 having a transverse opening therethrough in which is mounted a plunger pin 103, held retracted by a forked spring 104 straddling said pin and en 'aging suitable slots therein. This gear is adapted to mesh with andbe continuously rotated by the gear 105 mounted on the form cylinder 25. The side of the pin 10:, is beveled on the face thereof resented in the direction of rotution of t \c gear 102, and said gear is spaced away from the frame 21 sufficiently to a-fi'ord a clear field or rotation for said in. Carried by the side of the D-roll a jacent to said gear 102, and substantially diametrically opositc the recem in said roll, is a fixed abutment L06 projected beyond said roll toward said gear with an inclined face presented oppositely to the direction of rotation of the gear, so as to be in the path of the pin 103 when said in is rojected into its operative position. ivotal y moimted on the rame of the machine so as to be ca able of being interposed therebctween an the gear 102, is a lever handle 10'? having a beveled abutment 108 theleon rising from the lever 10? and descending thereto substantially at right angles. The said lever handle carries a latch member 109, preferably a sprin r tongue, adapted to sustain it in the mi position. One end of the said lever carries a tappet 110 ada ted to operate a.

circuit closer when the ever is raised, to

close an electrical circuit, and to open it or permit it to automatically open when the ever is lowered. This circuit closer comprises a fixed terminal 111 and a spring contact 11:2 opposed thereto, and adapted to be engaged by the tappet 110. The D-roll 82 carries on its other end a band 113 preferably of metal, and mounted ad'acent to said band is a brake shoe 114 carri ing brake head 115 having a project' levcr arm 116. Mounted on the same sha as the said brake head, is a lever arm 11'? carrying an adjustment screw 11S, adapted to engage the brake lever arm 116, and set the brake, and an armature 119 on the free end thereof.

Carried by suitable su ports 120 mounted on and insulated from t he frame 21, is an ordinary electro magnet 121. One terminal of the magnet is in electrical connection with a source of electrical supply, as one pole of an ordinary dynamo circuit, and the other is in similar connectiomwith a commutator brush 122 in rmanent contact witha shaft 26. Pivots ly mounted adjacent to the said commutator, and in electrical connection with the other pole of said circuit, is a spriu pressed brush 124 normally held away from said commutator by a stud 125, and adapted to contact with a projection 126 carried by said commutator, with each rotation thereof, and to be raised thereby slightly to insure a ood contact and the return to normal. T is arrangement results in a good electrical contact and that timely energizing and dcnergizing of the magnet, necessary to secure a timely brakin action on the D-roll, and a release thereof which will cause the braking action to be butloug enough to prevent any tendeucv of the D-roll to over run.

'lhc electrical connections of the machine aside from those feeding the resistance coils in the several cylinders and rollers and the drying attachment, to be hereinafter referrccl to, are illustrated in Fig. 11 in a by a swingconventional way. In said view, the terminal wires of the dynamo or other source of power are shown at 127 and 128, the said wire 12? having one lead to the magnet 121, and the other said wire, 128, having one lead 130 through a lamp 131 to the brush 124. The other terminal wire 132 of the magnet leads to the brush 122 and has a branch wire 133 leading therefrom to the switch member 112. The switch member 111 is in direct electrical connection by the wire 134 with the terminal wire 128. By this wiring, it will be observed that when the lever 107 is lowered to initiate the rota tion of the D'roll, the circuit closer 111, 112 is open and the magnet 121 is energized solely through the circuit including therein the commutator 123 and the commutator brush 121, thus setting the brake 111 mnmentarily once during each rotation of the D-roll and the form cylinder; but that when it is raised, the said circuit closers are closed, thus energizing the magnet by a continuous circuit, setting said brake during all periods when the means starting the D-roll is thrown out of the operative position. This arrangement insures such a timely stoppage of the D-roll after it has passed the point of frictional engagement with the plate on the plate cylinder, as to prevent any over run thereof under momentum, and such a holding thereof when not printing, as will avoid any creeping from any source whatever. it will be observed that the pressure exerted by the brake 111 may be so regulated by the set screw 118 as to permit the rotation of the D-roll through its frictional engagement with the plate cylinder, in case the lever 107 is raised before the completion of the rotation, while instantly checking all movement when the flat of the said roll is tangent to the form cylinder.

The paper feed mechanism comprises three cooperating mechanisms, that relating to the support of the paper roll and its feed to the D-roll and form cylinder; a damping attachment by means of which the web may be fed preferably dry before, and be wetted down only as it passes thro h the machine, and the drying and re-win mg mechanism by means of which the web after receiving the imprint is put in convenient form for subsequent treatment, or removal from the press, without danger of being blurred or smut-ted, and without limitin the speed of operation of the machine. T 1e first two of these are reasonably necessary in a machine of this character, but the last may be modified or dispensed with if desired.

Sup orted on the frame 22 is a paper reel 135 a opted to receive a roll of paper web 136. A so supported by said frame is the wetting mechanism between which and the Tool 135 are guide rods or rollers 137-138. IYBB" Mounted on the frame 21 adjacent to the D-roll, are the guide rollers 139-140, over which the web passes. and by which it is trued up before passing to the printing mechanism. The rollers 139 140 are udjustablo toward and from ouch mhcr by any desired means as the set screw 1-11.

lhe damping mechanism comprises at fountain 1-12 in which are uuuuuml two spreading rollers 113-144 adapted to be sub merged in the water or the water and chemieals or solvents, in said fountain. The roller 144 may be adjusted toward and from the roller 143 by means of the set screw 115. thus regulating the quantity of fluid carried over by the roller 143 to the distributing roller hereinafter referred to. Mounted above one of these rollers as 143, and adapted to receive a thin film of moisture therefrom, is a distributing roller 146 over which the paper web 131'- )asses to receive sufiirirut moisture on its l ou-er rllll'flltl' to soften the paper and prepare it for receiving an imprint. 'lhese rollers 143, 1-1-1 and 116 are driven solely throu h the paper web passing over the last named. I have found in practice that by dampin one side of the paper only and immediately before feeding it to the printing mechanism, the sur face to be printed may be softened suf ficicntly to give that flexibility and affinity for iuk necessary to insure the proper taking up of the ink deposited in the intagliu cuts, and that slight depression into said cuts incidental thereto. without so destroying or iujuriously affecting the sizing of the paper. as to necessitate a refinishing thereof after drying. 1 space the dam iug mechanism away from the printing mec 131liuu as shown in order to afi'ord ample opportunity for the moisture to Jerome thcrou hly diffused over and to permeate the sur 'uce of, the paper before entering the printing mechanism, although I have not found this absolutely essential. It is preferable, however, when running at high speed. T 0 meet all the requirements of use however, I provide the machine with e supplemcutal dumping mechanism consisting of the fountain 1 1? in which the roller 140 runs so as to be capable of ap 'ilyiug' water in the paper just as it enters the printing mechamsm. The fountains 142 and the supplemental fountain 147 each with its spreading roller, may be used in coiflliiction with each other, or either may used alone.

To replenish the supply of water in the fountain [-12, l place said fountain in comuuiuicutiou with a reservoir 1-18, through a pipe 149. The inlet to said pipe is controlled by a ball valve 150 the ball of which is of magnetic material, actuated through a ma net 151, the terminals of which are in circuit with a source of electrical supply through a relay 152 actuated Ill) through the operation of the lever 10?. the wiring being such that when the lever is raised, the relay will open the local circuit and close the valve, thus shutting oil" the supply of water flowing from line reservoir 14-8 when the feed of paper ceases, and that when the said lever is down and the press. is

running. water will be fed to said fountain in quantities substantially equaling that bein constantly used.

T find that under some rircuiaslanta's it i-r desirable to provide the roller H3 with interior heating appliances. as resistance coils not shown.

The wirin of the circuit controlling the relay 15:? an the local circuit itself, is substantially as follows: The terminals 175-1T6 of the magnet of the relay are respectivel in electrical communication with one switci member 112, and with one pole of the main circuit. The terminals 17? and 178 of the magnet 151, are res )ectively connected to one pole of the Inca circuit, and with the contact of the said relay. the lever of said relay being connected by the wire 179 with the other pole of said local circuit, an arrangement which reverses the ordinal telegraphic relay, thus causing the. closing of the local circuit when the relay magnet is energized. This construction of relay being well known in the arts, the parts thereof are referred to withoutecial reference letters and are not describe-t in detail.

Disposed above the. D-roll S2 as to allow a clear field for the printed web. is a heated roller ISO. and extending from this roller to the frame 2'. are a plurality of resistance coils 1S1 suitably incased and inclosed in a covered drying box 182. The said frame '22 has a suitable guide rod or roller and a windi reel 155 below it for receiving and re-win iug the printed web. This reel is driven by a gear 156 carried thereby and a gear 157 driven by a friction clutch 158, one member of which carries a sprocket wheel 159 driven from a sprocket wheel on the sha ft 70 by a chain 160. This friction drive is provided to compensate for the variance in the s eed of the reel 155 due to the increasing ialnctcr of the roll of web. The shaft of said car 157 is composed of two concentric sha s. one of which carries the said gear and one member of the clutch. and the other "of which carries the sn'ocket- 159 and the movement.

to pass continuously through said coils, being shown at 174. The. plates 172 are ordinary engraved plates properly bent to shape. and may be attached to the cylinder :55 in any desired manner. The abutting ends of said plate or plates are preferably so positioned as to up )roximately register with the flat of the 0-1-0 l. thus allowing for the slight excess movement of the. form cylinder upon each rotation thereof.

The operation of the herein described rint i11 machine is substantially as fol ows: W ien power is applied to the main shaft through the pulley 24, the form cylinder 2. is continuously rotated through the gear system 27. and the inking mechanism is driven from the gear 105. thus inking the plate or dates immediately after an impre:- sion has ecu taken therefrom.

While the various mechanisms embodied in the machine are or may be all driven from the shaft '23 in such synchronism as to have each perform its functions in a timely manner relative to the others. the operation of each such will be described independently of the others in the interests of perspicuity. The distributii and form rollers ink the plate or plates in the usual and well known manner which is not material to the invention and will not be described in detail.

While the form cylinder rotates continuously, the wiper cloth feed mechanism may be thrown in and out of gear through the clutch 32 to cause the cloth to be fed through the machine or not as desired. The hearings or frames 38 and the shaft mounted in the bearings 37. however. and their rollers 36 and 35, are given continuous lateral reciprocation through the strap 43 and eccentric all and the arm 39 and eccentric 40. said eccentrics bei respectively from the bevel gear 31 througi the shafts 45 and 41 in a manner to cause both said rollers to have a simultaneous equal movement in the same direction. To start the feeding movement of the wiping cloth. the members of the clutch are thrown into mesh with each other, thus causing the endless belt (53 to be carried around the various rollers 35. 36. 4?, .31, 62 and 52 by the rollers 47 and 19, which last mentioned rollers are positively driven by the chain and sprocket mechanism 50. The end of the wiper cloth 53 is then passed under the rollers (36. (58 and and inserted under the flap 64 of the belt 63, whcreafter it is fed relative to the form cylinder by being passed with said belt asa backing under the roller 54. over the roller and under the form cylinder lo the roller 36 on the opposite side there of beneath the inking mechanism. to the rollers 47 and 4-8 by means of which. as heretofore stated, it receives its feeding The speed of rotation of the roller 5-1 may be retarded by setting the.

brake 58 on the drum 56 by the braking mechanism.described, the construction of said roller and its engagement with the roller 35 preventing such slippage of the' cloth and the endless belt as will prevent said cloth being drawn perfectly tight across the plates 17:? on the cylinder 25. The adjustment screws 33 may he used to regulate the pressure of the roller 51 against the roller 35 which will aid in securing the desired tension of the cloth, and the rollers 35 and 54 may be moved toward and from the form or plate cylinder by the actuation of the worm 51. to secure av sufiicient. wiping surface of the cloth to thoroughly wipe, clean and polish the plate or plates. As the cloth leaves the rollers 47 and 48 it is passed around the shaft 50 which at this stage is run as an idler, and the guide rollers or rods and 67 to the shaft 70 which is driven by the friction clutch 71 at a speed varying with the diameter of the roll of cloth thereon, the inked side of the wiper cloth being presented ontwardly. The said cloth in passing under the form cylinder, has a general direction of movement opposite to that of the contacting surfaces of the plates and by reason of the lateral reciprocation of the rollers 35 and 3'3, a substantially circular movement is imparted thereto which tends to not only thoroughl wipe the surface of the said plate or p ates, but to scrub and polish same in a manner to avoid any possibility of streaking through the texture of the cloth itself. It will he observed that the same cloth wipes and polishes the plate or plates, and that these functions are performed at different points of the cloth so that a fresh clean portion thereof is always presented as a finishing portion. Hence portions slight-1y soiled in Wiping a portion of the plate or plates upon one part of a rotation is used for removing the greater portion of the ink from the late or plates during a succeeding part of such rotation and sub- ,sequent rotations; and is disposed ultimately adjacentto the inking rolls so that the subsequent wiping and lishing is done bjv portions of the cloth which are gradually c eaner=pro mrtionately to the distance from said rolls. This construction is important as it results in a machine wherein the. wip ing and polishing is done by a cloth which is never thoroughly saturated with ink and wherein the substitution of fresh clean cloth does not require the shutting down of the machine. It is also desirable in that the cloth being pressed against the late or plates by the tensioning'of the clot 1 and a reinforced flexible backing therefor, a erfect engagement; of the wiper with said I) ate 0: plates is assured: This tensioningof the clothis alsoan important feature, as it in. sures the thorough cleansing and polishing of the plate or 113105. \Vhcn the entire strip of cloth has cen run through the machine und wound men the shaft 70, the clutch 71 is released tn'ou h the nut 75 and the end of the roll of clot l on the shaft 70 is pass-ed under the rollers or rods 68 and 6.) and fed throughthe machine as above described only with the reverse side contactin with the plate or plates. After this seconc run, to avoid obstructin the machine, the clutch 71-78 on the sha t 76 is set and the cloth is wound thereon.

While the.- machine is not. printing, the lever 10? may be raised, thus permitting the gear 102 to run idly as will more fully appear hereinafter. When said lever is thus raised, the tappet. 110 actuatcs the circuit closer 111112 to close thecircuit. energizing the ma net- 121, thus setting the brake shoe 114 and preventing: any excess movement of the D-ro l. The closing of this circuit, also actuates the relay 152, thus closin the valve 150, and cutting otf the supply of water beii fed to the fountain 142. Said lever is he :1 in the raised position by the latch 109 which springs outward and engages the top of the frame 21.

In printing, the end of the aper web 136 13 passed around the guide r s 137 and 138, over the roller 146, between the rollers 139 and 140, between the D-roll S2 and the plate or plates 172 on the form 0 linder 25, upward and over the drying r0 er 180,through the drying box 182 over the coils 181 therein, and about the guide roller 0! rod 154 to the reel 155. When the web is so threaded, the machine is ready for the start. The power beinghon. the form cylinder 25 is ro tated, but te fiat of the D-roll being tangent thereto, or on a plane parallel to a line tangent thereto, it is necessary to give said D-roll an initial positive impulse sufiicient to bring it into frictional engagement with the plate or plates 17) on the form cylinder. To start the printing operation, itis merely necessary to drop the lever 107 between the gear 102 and the side frame 21, the contacts 111 and 112 thus being permitted to Spring apart, denergizing the magnet 121 and releasing the brake 114. As said rotates, the pin 103 carried thereby engages the bevel 108 on said lever and is forced inwardly to a point when the bevel on said pin e gas the bevel on the abutment 106 on the 81 e of the D-roll. Thereafter said D-roll is turned by said gca r to an extent, equaling the le h of the bevel 108 which is sufficient. to bring the D-roll into the re uisite frictional en- I agement with the p ate 172. With the )reaking of the circuit; throu h the switch members 111-412, the brake shoe 114 is released through gravity and raises the armature 119 from the core of the magnet. 121. Substantiall simultaneousl with the engagement o the D-roll wit the plate 172,

the pin 103 passes from the abutment 108 and recedes into its socket, permitting the subsequent rotation of the D-roll to be under friction solely. It will thus be observed that the D-roll receives one positive im wise with each rotation thereof, and therea ter i rotated at the same peripheral velocity as the form 0 linder and plate or plates thereon. The re ative diameters of the form cylinder and of the D-roll, the respective gears 102 and 105 being of equal diameter, is such that said D-roll gains slightly on said pin 103, thus providing a slight interval of rest between successtve rotations. If it be found that the pressure of the D-roll on the plate or plates of the form cylinder, is too great or insulficient to secure a good imprint, or to insure the proper rotation of the former, this pressure may be regulated by turning the handle 89 in the proper direction, thus either pzrmitting the springs 85 to raiw the D-roll arings, or com ressing said springs and thus lowering said arings. The worm and worm wheel construction described not only permits a micrometer adjustment of this pressure, but simultaneously adjusts both hearings in the same degree, thus obviating the dilficulties encountered when each bearing must be adjusted separately. As the D-roll approaches the limit of its rotation, the tappet 126 approaches the brush 124, and simultaneous] with the disengagement of the plate on the form cylinder and the D-roll through the flat thereof assuming aposition substantially tangent to said plate, said tappet engages said brush momentarily closing the circuit to the magnet 121 and setting the brake 114 throu h the attraction of the armature 119 the use lation of the lever 117 and the power applied through the screw 118 to the lever 116 carrying the brake head 115. This instantly checks the D-roll and overcomes any tendency thereof to over run under momentum. Assaid tappet leaves said brush, however, the circuit is again broken. denergizing said magnet, releasing the brake and freeing said D-roll preparatory to the next rotation. The duration of said contact should be such as to hold said D-roll stationary for a period substantially equaling the rest of the D-roll, althou h as the starting impulse is positive, the rake 114 will not materially interfere with the proper and timely initiation of the start of the rotation of said D-roll. The D-roll thus comes to rest after each rotation, the duration of which rest is dependent solely u n the gain of said roll upon the gear 102 uring a single rotation. \Vhether this be relativel more or less (it never being large) the -roll always starts at the same relative to the plate, this interval 0 restcompensating only for those differences in the diameters of the form cylinders and plate orplates thereon. and of the D-roll omt which are unavoidable mechanically and by reason of the varying thickness of the blanket and its hacking. T has it will be obv crved that the D-roll, in printing, is moverl intermittently only, being brought to a dead stop and positively started. yet moving during the interval when the imprint is being taken, in )erfect unison with the plate and plate or orm cylinder: and that notwithstanding the slight differences in the diameters of the form cylinder and the D-roll, said roll is always in perfect register with the plate or lates upon the initiation of the rotation oi the former.

Inasmuch as the D-roll is turned during the printing interval through frictional engagement with the plate or plates on the form cylinder, and as the quality of the work depends upon an even and continuous rotation of the D-roll and a perfectly smooth blanket, the capacity of the machine as well as its elliciency is materially in creased by the automatic blanket take u described. U on each rotation of the D-roll the flexible run 100 of the disk 99 engages the abutment 98 of the lever 95. and if the blanket is properly tensioned, the resistance to the depression of said lever by the blanket, will be greater than that exerted by the rim 100, thus causing the depression of the latter and permitting the lever abutment to pass same without impeding the movement of the D-roll. If, however, there be any slack in the blanket, the lever 95 will be depressed, the awl 101 carried thereby turning the slut 91 through the ratchetwheel 93 thereon. thus taking up such slack, the pawl 94 holding all slack taken up. The rotatable disk 99 is preferable as the circular rim thereof not only presents a contact surface which varies without materially changing the relation of the various parts, thus avoiding wear, at

one point, but because the said disk being free to turn, has such movement as to secure a rolling engagement and disengagement with said lever upon each rotation.

The rollers 143 and 144 in the damping mechanism take up water as they are turned and apply it to the roller 146 which in turn applies it to the under side of the web, being that side which contacts with the plate or plates. These rollers being spaced several feet from the form or plate cylinder, are used only when the press is running at high speed. a short interval being desirable to permit the water to permeate the surface of the paper. 'hen desired. however, the roller 140 may be used alone to dampen the paper immediately before cnterilpg the printing mechanism. This latter have found to be quite as efiicient as the other damping mechanism, particularly when the s eed of the press is somewhat. lower. With either damping mechanism, however, the redeiinergizing-it, as it may be sultattained is the superficial damping of the paper immediately prior to its entering the printing mechanism, thus obviating the resent ractice of wetting down by ampene cloths for a considerable period prior to use, a practice which frequently results in the partial or entire removal of the sizing of the paper and the necessity for refinishing the paper after prmtmg thereon. The pa r is fed throu h the machine by the D-rol and plate or orm c lmder, and hence the feeding thereof wil be discontinned with the raisin of the lever 10?. As the paper leaves the D-roll, it passes about the drying roll 180 and through the heating box 182 over the electric heater 181 where the dampness is thoroughlg removed from the paper and the ink 0 t e imf iress itself dried more or less pprfmtly. mm the heating box 18:2 the we passes over the guide rod or roller 154: to the rewinding reel 155 where it is rewound pre aratory to further operation or treatment. 0 avoid a possible adhesive of the printed web, a tissue web from the reel 161 is laid and wound between the successive plies of the re-wound web as shown. I

The hereinbefore described operations are carried on substantially simultaneously as to time but in sequence as to the general resuit, and with practical continuity, the machine being capable of running at high speed, the nature and uality of the work being considered. It as practice that the web may be run through the machine and be dampened, nrmted and dried as described withoutlikelihood of breakage thereof, and with practically uniform quality of work- The dampening of the paper iimnediately prior to taking the impression has been found to impart to the high. grade pa er required in this-class of work, all the c aracteristics essential to se cure a good imprint while not caus ng the ink to 5 read, or injuring or destroying the finish oi the paper.

In the foregoing description of the operation of the machine, I have referred more particularly to the various operations 1n printing a continuous web without referrin in detail to the operation of all the mec anisms incidental thereto, the power transmissions and the other minor mechanisms, the o ration of such being apparent from the d iiailed description of their construction and arrangement.

The raisin or lowerin of the lever 10? has the functionof not on y controlling the movement of the D-roll but also the electrical circuits ermanently ener 'zing the magnet 121 an actuating the re ay 152, or p uired to supply wateror other solvent to tie fountam '142. Thaintermittnt circuit is not controlledby said layer handle however.

been found in The operation of the means cutting off the supply of water is substantially as follows: The magnet 151 is included in a normally closed local circuit, and the terminal wires of the relay magnet are included in the main circuit through the switch 11l11'2. Hence when the lever 10? is lowered, said switch bemgopen, the local circuit is closed, thus energizin the magnet 148 and openin the valve lfiO by raising the ball thereof. hen, however, the lever is raised and said switch is closed, the circuit to the magnet 121 is not only closed, but the circuit includin the relay magnet is simultaneously close thus breaking the local circuit and permitting the ball of the valve to drop and close said valve.

It is not my intention to limit the invention to the details of construction shown in the accompanying drawings, such bein merely that form of the invention which has been found satisfactory in one class of under surface printing. In orderto increase the capacity of a machine, the dimensions of thevarious parts may be increased to accommodate the machine to a greater number of lates, or a wider web, or the various mec anisms may be multiplied so as to adapt the machine to the use of several webs, a construction which has notbeen illustrated or described as involving no modification of the invention, but merely a duplicate of parts.
