PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 770,487, dated September 20, 1904.

Application filed February 11, 1903.

T all whom it may concern:

Be it known that I, J OSEPH WTHITE, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Printing- Machines, fully described and shown in the following specification and the accompanying drawings, forming a part of the same.

The purpose of this invention is the construction of an efficient printing-machine in which the product receives the design indirectly from the form through the agency of a transfer-surface. In a printing-machine of this nature, where a transfer-surface is employed in addition to the usual form and impression surfaces, it is desirable to have these surfaces arranged so that they can be readily manipulated for various necessary purposes, and it is also desirable at times to suspend the printing relation of these surfaces without otherwise interrupting the operation of the machine. Besides providing for these objects my invention makes it possible to have a more compact and a simpler machine than has hitherto been used for this style of printing. It is also possible by my invention to obtain a simpler and more efiicient inking arrangement than has been possible heretofore. To illustrate these and other points which fall within the scope of the invention, I have chosen as a preferred form a machine where the form, transfer, and impression surfaces are each formed on a constantly-running cylinder; but as there are other designs than the one shown to which the principles of this invention can be applied it is to be understood thatI do not limit myself to the form shown in the claims.

Referring to the drawings, Figure l ,is an elevation showing so much of a printing-machine as is necessary to illustrate the invention. Fig. 2 is a partial end view. Fig. 3 is a view showing the cylinder-moving mechanism'in another position. Fig. 4 is a detail view.

The frames 1 of the machine support the form-cylinder 2, transfer-cylinder 3, and impression-cylinder et. WVhile any of the various kinds of form or design surfaces used in Serial No. 142,973. (No model.)

the art of printing may be employed in this machine, I have chosen the flexible aluminium plate 5, which is shown stretched on the impression-cylinder by means of the clamps 6, which are fastened to each end of it.

In planographic printing, where an aluminium plate is employed, the plate is first dampened by water-rolls and then inked by ink-rollers. Any suitable method for manipulating these rollers may be employed, and as they do not form a part of this invention these rollers are shown diagrammatically, the ink-rollers at 7 and the water-rollers at 8. In order to lessen the number of these rollers usually employed and to simplify this part of the machine, the form-cylinder is caused to make a plurality of revolutions to each impression. In the illustrated machine, which is thepreferred form, the form-cylinder makes two revolutions to each impression. As there are four inkingform rollers shown, this makes an equivalent ofeight rollers if the machine were constructed so that the formcylinder made but one revolution to each impression. The plate-surface occupies substantially half .of the circumference of the cylinder 7 and assists in the distribution of the ink, the other half of the cylinder being used as an ink-slab 9, which cooperates with the form-rollers to produce the necessary distribution of the ink.

The shaft 10 of the form-cylinder 2, to which it is fixed, finds its hearings in the boxes 11, mounted in the frame in the usual manner, and these bearings are adjustable by means of the screws 12 13, so that the desired pressure can be given to the transfer impression to suit varying conditions imposed by different thicknesses of design-plate 5 and transfer-blanket 15, &c. It is to be understood that different means of obtaining the desired pressure may be employed; but the preferred form has been described and illustrated.

The transfer-surface consists of a layer or blanket of a suitably-yielding materialsuch, for instance, as a web of cloth and rubber formed or stretched on the surface of the cylinder 2. This blanket, as shown, has the forward end clamped in a recess of the cylinder by the bar 16 .and fastened on the rear end to the rod 17, by which means it is tightly stretched on the surface of the cylinder.

The operation in which the transfer-surface receives its design from the form and transmits it to the material to be printed upon, in this case a hard unyielding materialsuch, for instance, as a sheet of tin, wood, or glassis as follows: On the second revolution of the form-cylinder and after the design has been suitably inked by the ink-rollers the transfercylinder is in a manner to be hereinafter de scribed brought into printing relation (in this case a rolling contact of proper pressure) with the form-cylinder and in this position receives on its surface afilm of ink which is the reversed equivalent of the design on the aluminium plate. After this impression is made the transfer-cylinder is moved out of contact with the form-cylinder and into printing relation with the impression-cylinder, in which position it imparts its design to the sheet of material which is interposed between it and the impression-cylinder, thus completing its function.

' While the transfer-cylinder 3 and impression-cylinder 4 may be of any desired ratio to the form-cylinder 2, they are preferably, as illustrated, two-thirds of the size of the form-cylinder, and when these cylinders are geared together, as shown in the drawings, for instance, by gears 18, 19, and 20, which are fastened to the respective cylinders, so as to rotate in unison, the transfer-cylinder will make three revolutions to two revolutions of the form-cylinder, in which time the machine completes its cycle of operation. The impression-cylinder may be of any suitable ratio to the transfer-cylinder; but, as shown, it is preferably of the same size as the transfercylinder and rotates in unison with it at the same surface speed. It is fast to its shaft 2 1, which finds its bearings in the adjustable cylinder-boxes 25, which are controlled by the screws 26 and 26 to suit varying thicknesses of material to be printed. The impressioncylinder is preferably provided with stops 27, against which the sheets to be printed on are adjusted; but as the method of adjusting the sheet against the stops do not form part of this invention they are not shown.

It is desirable to have the form-surface come in contact with the transfer-surface but once for each impression, and the transfer-surface should only come in printing relation with the impression-surface when the sheet to be printed on is fed between the cylinders, which in the machine illustrated is on every third revolution of the transfer-cylinder. In order to accomplish this result, the diametral relations of the printing-cylinders are effected, so as to first place the form and impression cylinders into printing relation to each other and then have the transfer and impression cylinders in printing relation, (in which latter position the transfer and form cylinders will be placed out of contact.) While this may be done in various ways, (for instance, the form and impression cylinders might be made to move to and from a fixed transfer-cylinder,) it is preferable to move the transfer-cylinder first into contact with the form-cylinder and then into printing relation with the impression-cylinder. The means by which this can be accomplished may be varied widely, andI do not limit myself to the method shown; but

the following is a simple and eificient method r of accomplishing this result.

The transfer-cylinder 3 (see Fig. 2) is mounted on an eccentric shaft 28, on which it runs loosely, its bearings being at 29 in the heads of the cylinder. This shaft finds the bearings for its eccentric ends 30 in the bushes, 31, mounted in the side frames 1 of the machine. The desired eccentricity of bearing might be obtained by making the bushes 31 eccentric and having the ends of the shaft concentric with the cylinder: but it is preferable in this machine to have the shaft eccentric, as shown. The means for operating this shaft may be varied widely; but it is preferably operated and controlled in the following manner: Fast on the end 32 of the cylinder-shaft is the wormwheel 33, which is rotated by the constantlyrevolving worm 34 on the shaft 35, which in turn receives its motion from the miter- gears 36 and 37, the gear 37 being fast on the shaft 38, which is mounted in the side frames, said shaft having a spur-gear 39 fast to it on the inside of the frame. This gear 39 receives its motion from the gear 4:0,which is one member of a compound gear which is loosely mounted on the stud 4:1 in, the side frame of the machine, the other member, 42, of the compound gear meshing with the cylinder-gear 18. Now it will be seen that if this chain of gears were not interrupted or disconnected somewhere the transfer-cylinder would be constantly oscillating on its eccentric shaft between'the cylinders 2 and 4: and would come but in momentary contact or printing relation with these cylinders. It is desirable, however, to control the amount and time of dwell of the transfercylinder with each of the other cylinders. The shaft 35, on which are mounted the miter 36 and worm-wheel 34:, is supported in bearings 43, which are formed on the three-armed lever 4A, and which is loosely pivoted by its hub 45 on the hub of the miter-gear 37, said hub being shown in section in Fig. 3. By this construction it will be seen that the miter-gears remain in proper mesh and that the worm can be constantly rotated at any angle of movement of the lever 44. If this lever is moved so as to bring the worm into mesh with the worm-wheel, the shaft 28 will be caused to rotate and so move the cylinder. The means for controlling the time and amount of this movement can be widely varied; but the means shown is preferred. 'As the three printingcylinders are shown in line (although they might be otherwise placed) it is obvious that it requires a one-half revolution of the eccentric cylinder-shaft to move the transfer-cylinder 3 from printing relation with one cylinder to a position where it is in printing relation with the other cylinder.

- Fast on the eccentric shaft end 32 is a disk 46, which rotates with the shaft. One arm of the lever44 holds a roller 47, which rides upon the periphery of the disk 46 and in this position tends to keep the worm 34 in mesh with the worm-wheel 33 against the action of the spring 48, which tends to throw it out of mesh. The periphery, of the disk 46 contains two diametrically opposite notches 49 and 50 and two notches 51 and 52, which are also diametrically opposite each other, the notches 49 and 50 being used in the normal printing movements of the transfer-cylinder 3 and the notches 51 and 52 being used for the purpose of holding the transfer-cylinder 3 out of action with both the form-cylinder 2 and impression-cylinder 4 in a manner to be hereinafter described.

Assume the notch 49 to. be in cooperation with the roller 47, as in Fig. 3. When in this position, the spring 48 has thrown the wormwheel out of action with the worm, and consequently the eccentric shaft 28 is stationary. Alongside the disk 46 and centered loosely on the disk-hub is a guard-plate 53, which is part of the lever 54, from which it receives its movement. Theouter edge of this guardplate is concentric and of equal diameter with the disk 46. When the disk is moved alongside the disk-notches, as shown in Fig. 1, the guard raises the roller 47 and forms, with the disk, a continuous surface. The worm is thrown in mesh, and thus starts the movement of the eccentric shaft. Fig. 1 shows the transfer-cylinder 3 in con tact with the form-cylinder 2, the printing having just been completed and the eccentric shaft just starting to make itshalf-rotation. which will bring the transfer-cylinder 3 into printing relation with the impression-cylinder 4. i

The means for moving and controlling the guard-plate 53 may be varied widely; but the preferred form is that illustrated in the drawings. Connected to the lever 54 is a forked rod 55, which has a stud 56, operated by a cam 57, fast on the end of the cylinder-shaft 10, said cam being so shaped and timed that just after the printing operation between cylinders 2 and 3 is completed, as is shownin Fig. 1, the rod 55 is moved upward, so as to bring the plate 53 over the notch 49. The worm is thrown into mesh and through its connected gearing rotates the eccentric shaft, carrying the notched disk 46 around withit. It will continue to rotate as long as the guard-plate remains in the position shown; but the lower concentric ring 58 of the cam is of such a length that it holds the guard-plate 53in place until the notch 51 has passed it, when it is moved back, so that when the notch 50 comes opposite the roller 47 the roller drops into it and the spring 48 moves the worm out of mesh and the eccentric shaft is brought to rest with the cylinder 3 in printing relation to the cylinder 4. y

- The action of the cylinder-moving mechanism is the same in moving the transfer-cylinder into printing relation with the form-cylinder as in moving it into printing relation with the impression-cylinder.

The cam 57 is properly timed for both operations for the following reasons: The design is received on the transfer-cylinder during its first revolution at the position a, and it begins to give its impression to the plate on its second revolution at the point 5, which is diagrammatically opposite, so that it gives up its impression one and one-half revolutions after it receives it. Now one revolution of the form-cylinder (on whose shaft 10 the cam 57 is mounted) is equal to one and onehalf revolutions of the transfer-cylinder 3. The cam thus bears the same relation to the first printing or transferring operation as it does to'the second or the operation of printing on the sheet. For instance, when the transfer-cylinder has made one and one-half revolutions beyond the position shown in Fig. 1 it will have just completed giving its impression to the sheet at b, and the cam 57 will have moved one complete revolution and the plate 53 will just have covered the notch 50.

It is desirable to throw the transfer-cylinder out of printing contact with its coacting cylinders. This is done for various purposesfor instance, to distribute the ink thoroughly' before starting printing or when a sheetis not fed for some reason. This may be done by the following means: The rod 55 is provided with a slot, at the ends of which are recesses 59 and 60. The lever 54 has on its end a stud 61, on the threaded end of which is fitted the hand-nut 62, which fits in the sockets at the ends of the slot. When in normal printing operation, it is in the socket 60, as in Fig. 1. In order to trip the cylinder, the hand-nut 62 is loosened and is moved up the slot and fastened in the socket 59, as in Fig. 3. In this position the plate 53 is held out of action with the roller 47. The shaft 28 will then be caused to make onequarter of a revolution instead of one-half of a revolution, as it normally does, for the notch 51 being unguarded the roller 47 drops into it and the worm and worm-wheel is thrown out of mesh. This position is shown in Fig. 3. When the printing action is to be restored, the nut 62 is moved back to its position in the socket 60.

I have shown the guard-plate as being controlled by the slot and hand-nut; but it is to be understood that other means might be used.

For instance, it might be arranged so as to be controlled by foot "or connected so as to be automatically operated.

During the printing positions of the transfer-cylinder the force exerted by the printingpressure is along the line of eccentricity of the shaft 28 and its end 30, and thereforedoes not tend to rotate the shaft 28; but in order to insure the eccentric shaft against any movement while the transfer-cylinder is in printing relation with either of its coacting cylinders it is desirable to lock the shaft when in these positions. A separate locking mechanism may be provided; but as it will be seen that when the transfer-cylinder 3 is perform ing its printing function the roller 47 is in the notch 49 or and is held therein by the pressure of the spring &8 this will serve to hold the cylinder locked in place. Considerable force tending to rotate the shaft would be required to remove the disk so as to displace the roller 47, although said roller can be readily raised by the guard-plate 53. It is also necessary to lock the transfer-cylinder in its tripped position when it is out of contact with its 00- acting cylinders. This might also be done by a separate mechanism; but the disk 46 and the roller on the lever 4A, backed up by the spring 48, will serve for this purpose also.

It is to be understood that the machine described and the mechanisms for accomplishing the different requirements of the machine serve as a specific illustration of the principles of this invention, and I do not limit myself, therefore, to such a design.
