color-Printing Machines, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to machines for printing various designs on fabric or paper of any kind or class in a plurality of colors, and the object thereof is to provide an improved machine of this class which employs stereotype plates or rollers and lithographic ink; a further object being to provide a machine of the class specified by means of which lithographic ink in its normal condition may be used and designs produced in fast colors without subjecting the printed designs to further treatment other than dry- .ing; and with these and other objects in view the invention consists of a machine of the class specified constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the'views, and in which 2 Figure 1 is a side view of my improved multi-color printing machine, or the operative parts thereof, the steam drying drums, the steam drying pipes, the suppl roller and the rewinding roller being not s own in this view: Fig. 2 a view of the opposite side of the machine, as shown in Fig. 1 with parts omitted and only the bottom part of the machine being shown: Fig. 3 a vertical section on the line 3-3 of Fig. 1: Fig. 4 a section on the line 4c4 of Fig. 1 and on enlar 'ed scale: Fig. 5 a section on the line 5% of Fig. 4: Fig. 6 a view of certain details of the construction looking in the direction of the arrow 6 of Fig. 4: 7 a diagrammatic side view of the machine and showing the movement of the sheet to be printed: Fig. 8 a section on the line 88 of Fig. 9: Fig. 9 a side view of 'a detail of theconstruction; and Fig. 10 a partial section on the line 1010 of Fig. 5.

In the practice of my invention I provide a main upright frame 1 comprising two side members 2 which are connected by transverse bolts 3 WhlCh may be arranged in any desired manner, but one of which is arranged near the bottom, in the construction shown, and the other two near the top, but it will be understood that any desired number of these .bolts may be employed. In the central bottom portion of the sides of the frame are vertlcally movable bearing blocks 4 in which 1s mounted a platen drum 5 which is made vertically adjustable by means of screws 6 provided at their upper ends with beveled gears 7, and a transversely arranged shaft 8 having corresponding gears 9 provided at one end with a crank wheel or similar device 10. In the top of the main frame is mounted a roller 11 having a shaft 12 mounted in vertically adjustable bearings 13, and said bearings are made adjustable by means of vertically arranged screws 14 provided with crank wheels or similar devices 15.

Mounted on the platen drum 5 and roller 11 is an endless platen belt 16 composed of rubber, rubber and canvas or any other suitable elastic material, and supported in any desired manner at one side of and at a suitable distance from the drum 5 and roller 11 and parallel therewith are two steam drying drums l7 and 18 arranged one above the other, and below which is a rewinding roller 19 between which and the drum 5 is a supply roller 20 on which is wound the sheet of material to be printed. Above the supply roller 20 are two drag rollers or rods 21 and 2 2 arranged one above the other, and approximately in the same horizontal plane with the upper drag roller or rod 21, and midway between the drum 5 and roller 11 is a roller 23, and between the roller 11 and the upper steam drum 17 is placed, in a horizontal plane, a plurality of steam pipes 24. This construction and arrangement being clearly shown in F igs.- 1 and 7.

The sheet 25, on which the desired design is to be printed, is wound on the roller 20 and is passed around the drum 5 and roller 11 in the direction of the arrows at, and from the roller 11 said sheet passes over the steam pipes 24, around the upper steam drum 17, then between the drums 17 and 18 and around the drum 18 and then connected with the rewinding roller 19. Arranged at the opposite sides of and-beneath the drum 5, are a plurality of ink preparing and applying devices or mechanisms 26 three of which ide' are employed on each side, as here shown but it will be understood that the number of these ink preparing and applying devices will be controlled by the number of colors which it is desired to employ in printin any particular design or designs. The in: preparing and applying devices 26 are all exactly of the same form, construction, and operation and a description of one will therefore apply to all. Each of these devices. employs in its construction a rigid rectangular frame 27 comprising parallel side bars 28 and an outer transverse end bar 29, and the side bars 28 are rovided with'outwardly directed angle mem ers 30 which are adjustably secured to an'gle brackets 31, which in turn are secured to the side members 2 of the main frame by screws or bolts 32, or in any desiredmanner, and the angle brackets 31 are provided with slots 33 through which are passed bolts 34, and by means of this constructionthe frame 27 is made adjustable toward and from the platen drum 5.

The side bars 28 of the frame 27 are pro ,vided adjacent to the drum 5 with recesses 35, and midway thereof with other 'recesses 36, and in the outer end of said frame is an ink font or holder 37 which is box-shaped in form, and ranges transversely of the frame, and mounted in the front thereof, which is open, is a transverse metal roller 38. Mounted in the recesses in the side bars 28 of the frame 27, and adjacent to the plziten drum 5, is a transverse stereotype mandrel 39 on which is placed a stereotype plate 40 which is cylindrical in form and on which is placed part of the design to be printed, and it will be understood that the design on the stereotype plate 40 of the stereotype mandrel 39 in the difierent ink applying devices or mechanisms 26 is different in form, but all of which taken to: gether make up the complete design to be printed. The shaft 41 of the mandrel 39, or the opposite ends thereof, are provided with bearings 42 which are made adjustable longitudinally of said shaft and radiall or toward and from the drum 5, and it wi 1 be understood that the longitudinal adjustment also adjusts the mandrel 39' transversely of the face of the drum.

The adjustment toward and from the drum 5 is etfected by screws 43 which press on the bearings 42 and this adjustment or movement is for the purpose of increasing or decreasing the pressure of the mandrelon said drum. The longitudinal adjustment of the mandrel or of the bearings 42 by which the longitudinal adjustment of the mandrel is produced, is elfected by means of screws 44. In order to accomplish this result the bearings 42 are provided with inner movable members 45 and the screws 44 are passed inwardly parallel with the shaft 41 and oper: ate on the members 45 and by manipulating the said screws at the opposite ends of the shaft 41 said shaft and the mandrel may be adjusted transversel of the face of the drum, as will be rea ily understood.

Mounted between the roller 38.and the mandrel 39 and in the same plane thereof andv beginning with the roller 38 are rollers 4647-'48 and 49 all of which are composed of rubber or have a rubber facing, and the rollers 38-4748 and 49 have a rotary movement only, and the roller 49 operates in connection with the stereotype plate 40. Mountedover and operating in connection with the roller 49 is a roller 50 composed of rubber or havin a rubber face, and rearwardly thereof an slightly below the roller 50 is another roller 51 preferably of metal. The roller' 50 has a rotary movement only, while the roller 51 has both a rotary and longitudinal movement.

Mounted at one side of the frame 27 in a bracket 52 is a longitudinally movable bar 53 composed of separate parts adjustably connected at 54, and the front end of which isforked and provided with a roller wheel. 55Iwhich operates in connection with a cam disk 56 fixed to the shaft 41, and the rear end of the bar 53 is connected with the corresponding end of the shaft of the roller 46, and mounted on the opposite ends of the shaft of the roller 46 are rock arms 57 pivoted to the side bars 28 of the frame 27 at 58, and which extend below the frame 27 and. areconnected by a cross bar 59, and mounted in the upper ends of the arms 57 is a roller 60 which is made to contact with the roller 46, but which operates in connection with the rollers 38 and 47 intermittently, and connected with the side bars 28 of the frame 27 are springs 61 which operate to hold the roller wheel 55 'in connection with the cam disk 56, and-to force the roller 46 into contact with the roller 47, which operation forces the roller 60 into the dotted position shown in Fig. 5, and out of contact with the roller 38, and the operation of the cam disk 56 throws the roller 46 into contact with the roller 38 intermittently, as above stated.

The end portion of the shaft 41 of the mandrel 39. opposite the cam disk 56 is provided with "a gear 62 which meshes with a smaller gear 63 on the corresponding end of the shaft of the roller 49, and the. opposite end of the shaft 41 is provided with a crank disk 64 provided'in its outer face with a 'diametric groove 65 in which is mounted a block 66 made adjustable by means of a set screw 67, and pivoted to the block'66 is an arm 68 which 18 connected with an arm 69 loosely mounted on the shaft 70 of the roller 38, and the arm 69 is provided with a spring pressed pawl 71 which operates in connection with a ratchet 72 fixed to the shaft 70, and this construction imparts to the roller 38 mogeu an upward and for-ward step by step move? ment through the ink 73 in the font or box 37.

- Each of the shafts 41 of each of the mandrels 39 of each of the ink applying devices 26, opposite the cam disks 56 is provided with a gear 74, and these gears mesh with drel shafts 41, as clearly shown in Figs. 8

provided with cylindrical heads 84 having and 9, said gears being rotatably mounted on sleeves 78 adjustable longitudinally on said shafts, and the gears 74 are held on the sleeves 78 by collars 79 having set screws 80.

The gears 74 are provided on their outer sides with ears 81 in which are mounted worms-82 which mesh with corresponding worm gears 83 on the sleeves 78 and the op posite' end portions of the worms 82 are radial holes 85 to receive the ends of crank pins or similar devices for turning said worms, which operation is performed by hand, and, the ob ect of this construction is to provide for the adjustment of the man? drel 39 circumferentially so that the design or designs on the-stereotype plates 40 may be put in perfect registration with each other. l

Mounted beneath and transversely of the drum 5 is a power shaft 86 one end of which is provided with a pinion 87 which meshes with the gear 75, and the opposite end of which. is provided with a belt wheel 88 and said shaft is also provided inwardly of the belt wheel 88 with a box cam 89 having a spiral groove 90.

Mounted horizontally and at the outer side of the main frame adjacent to and over the box cam 89 and in brackets 91 secured to said frame is a rock shaft 92, and said shaft is provided between the brackets 91 with a downwardly directed arm 93 the lower end of which is provided with a pin 94 which operates in the groove 90 of the box cam 89 and by means of this construction the shaft 92 is given a rocking rotary movement.

Theshafts 93 of the-rollers 51 of each of the ink applying devices or mechanisms 26 are'projected on the side of the machine on which the shaft 92 is mounted, and these I shafts are provided with grooved wheels 94 and the shaft 92 is provided with arms 95 which correspond in number with the number of ink applying devices 26, and which are provided with forks 96 having inwardly directed pins 97 which operate inthe grooves 98 of the wheels 94, and the object of this construction is to give the rollers 51 a reciprocatory longitudinal movement.

As hereinbefore stated the objectof this machine, or one of its objects, is to print a design on fabric, paper, or the like and especially silk, in different colors and at one not impossib e by reason of the operation, and to print said design in fast colors by using lithographic ink, this result has never heretofore been produced except by using stone or other tablets and by processes which made a number of operations necessary, or one for each color, but with my improvement, the desired object can be obtained at oneoperation, and the.

number of colors depending on the number of ink preparing and applying devices.

- In the old method of printing differentcolors by the use of tablets or prints the rfect registration of the different colors In the print, roduced was very difficult if fact that the article to be printed had to be taken from one machine to another, but with my imrovement the various adjustments provided or, or the adjustments of the printing inandrels of the different ink applying-devices,

provide means whereby the registration of the different stereotypes printing different colors can be exactly effected and the desired work accomplished in the best possibleorder,

and in the shortest possible time, and at one 1 operation of the machine.

It is a well known fact that lithographic ink is not a liquid or flowing body but is :more of a plastic or viscid character, and

this ink must in the operation of the ma- 1 chine be broken up. and entirely distributed so thatit will completely. cover the rollers 49 by which the colors are appliedto the stereotype plates, and thisresult is accomplished by the movement of the various rollers between the rollers 38 and the rollers-49 of the ink applying devices or mechanisms.

It will be understood that the rollers 49 are given a continuous movement by the gears 62 and 63, and the rollers 38 are given an intermittent or step by step movement by the parts 686971 and 72, while the rollers 46 and 60 are given a forward and backward movement by the parts 5355- -5657 and 59, all of the colors employed being also capable of rotary movement in the usual manner. In this operation the rollers 38 turn in the direction of the arrow a2 and pick up particles of the ink in the font or box 37, and the rollers 46 and 60 receive the ink from'the rollers 38 and apply it to the rollers 47 and in this operation the particles of ink are broken up and spread over the rollers 46-47 and 60. The rollers 51 in addition to having a rotary movement also have a longitudinal movement, and this operation takes the ink from the rollers 47 and,applies itto the rollers 48 and the ink is more finel and evenly applied to said last named r0 ers, and the rollers 49 take the ink from the rollers 48 and apply it to the stereotype rollers or mandrels 39, and in this operation the ink is completely and evenly applied to the rollers 49 by the rollers 48 and 50 and the 45 tact therewlth'.

rollers 49 are given a continuous, even and smooth coating of. said i soas to perfect the transfer oi" the ink by the rollers tat-to the' stereotype rollers or mandrels-zdh or stereotiylpe plates mounted-thereon It w be observed that all of the printing or stereotype rollers: 39 are mounted in an arc of a circle below andat-the sides of the platen drum 5, and by reason of the n fact that said drum is-vertically movable or adjustable it may be raised, when -red, above the said printing or stereotype rollers in order to permit of, and facilitate, the .operation of adjustin said rollers into the desired position an the adjusting of the stereotypefplates thereon, and this is one of the chief atures of aiplicants invention, another feature thereof eing the possibility of adjusting the stereotype rollers longitudinally and rotarily in order to cause the stereotype printin plates thereon to properly register, in the operation of printing a design of diderent colors at one operation on a strip of cloth or other material,

and means for effecting the longitudinal adjustment of said stereotype rollers, is clearly shown in Fig. at, and means effecting the rotary adjustment of said rollers is clearly shown in Figs. 8 and 9, and these so rollers are also, as hereinbefore stated, ad-

justable toward and from the platen drum 5.

Another feature of my invention, and wherein it difi'ers from others of its class is in the fact that the platen drum 5 is turned by friction of the stereotype rollers-39 and not by direct gearing, as'in other machines of this class, and this also facilitates the assembling of the various parts of the machine or press, and the adjustment of said rollers, as hereinbefore described, and by the scope of the appended claim without departing from the spirit of my invention or sacrificing its advantages. It will be understood that the steam drymantra ingdrums 17 and 18 may" beet Jason .torm and construction, and these drums to-" gether with the rollers 19 and 20,'the steam pipes 24: and the rods or rollers 21-and 22 may be supported in any desired manner, and in connection with the mainframe of the machine, or in any other we and, as

will be understood, the steam drying drums l7 and 18 and the steam pipes 24 are for the purpose of thoroughly drying the printed sheet, 25 or the designs prlnted thereon be fore said sheet is rewou-nd on the roller 19.

Having fully described my invention what I claim as new and desire to secure 'byLetters Patent is a In a machine ofthe class described, a

platen drum, and a plurality of frames mounted at the sides of and beneath said drum and each of which is provided with a stereotype roller operating in connection therewith, ink holders mounted in said frames, ink rollers mounted adjacent to and operating in connection with said ink holders and having a step by. step movement,

other rollers mounted ad acent to and opcrating in connection with the stereotype rollers and geared in connection therewith,

two independent rollers mounted between the ink rollers and the rollers geared in connection with the stereotype rollers, and one of which is in connection with the last named rollers, rollers mounted above and in contact with the two independent rollers and longitudinally movable, other rollers mounted over the rollers geared inconnection with. the stereotype rollers and in contact therewith, rollers mounted between the ink rollers and the adjacent independent rollers -and movable toward and from each, and adapted to contact with each alternately,

,and other rollers mounted over the inking rollers and adapted to bear thereon intermittently and always in contact with the last named rollers.

In testimony that I claim the foregoing as a my invention I have si ed my name in presence of the subscribing witnesses this 18th day of April 1912.
