MECHANISM FOR CONTROLLING THE INK-SUPPLY F PRlNTlNG-MACHENES.
Specification of Letters Patent.
Patented Oct. 16, 1906.
T0 on whom, it natty concern:
Be it known that I, DAVID W. J ONES, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented a new and useful Mechanism for Controlling the Ink-Supply of Printing-Machines, of which the following is a specification.
The object of this invention is to provide a new and improved device for controlling the inking mechanism of cylinder printingpresses, so arranged that the supply of ink can be controlled and regulated by the feeder of the press from the position where he ordina rily stands supplying sheets to the machine.
The accompanying three sheets of drawings illustrate enough of a cylinder printingpress with my improvements applied thereto to enable one skilled in the art to practice the invention.
Referring to the drawings, Figure 1 is a side elevation, partly in diagram, of a cylinder printing-press with my improvements applied thereto. Figs. 2 and 3 are small detail views illustrating parts of the operating connections. Fig. 4 is a rear. elevation, and Fig. 5 a side elevation, of part of the cylindertripping mechanism. Figs. 6 and 7 are detail views illustrating the operation of said cylinder-tripping mechanism. Fig. 8 is a sideelevation, and Fig. 9 is a rear elevation, of the ink-fountain-actuating mechanism. Figs. 10 and 11 are views similar to Fig. 8, ilustrating the parts in different operative positions,- and Fig. 12 is a small detail view.
illustrating the construction of a pawl hereinafter described.
Referring to the drawings and in detail, A designates the impression-cylinder, and B the reciprocating bed, of an ordinary tworevolution cylinder printing press. The bed carries the usual printing-form O.
F represents an ink-fountain which is ar ranged at the end of the machine. Ink is taken from the fountain-roller by the ductorroller D and deposited upon the ink-table I, which is secured to the front end of the bed. The ink is spread and rolled on the table I by .the usual distributing-rollers E and is taken from the ink-table by the usual form-inking rollers H, which latter apply and roll the ink on the form C.
r V The ductor-roller D is mounted in suitable arms 10 arranged on a cross-shaft, projecting from which is a lever 11, which connects by a link 12 to a vibrating frame 13, which has a roller 14 engaging a cam 15, mounted on the cam-shaft 16 of the machine. This camshaft is arranged in the usual manner to make one turn for every two turns of the impression-cylinder. The cam 15 is usually made in a box form, the inside line of which is alone designated in Fig. 3, the outer line of the camgroove being omitted, so that the arrangements can be clearly seen. This mechanism will vibrate the ductor-roller D at the proper time to take ink from the ink-fountain roller and lay the same up on the ink-table I. The ink-fountain-roller shaft 17 has a lever 18 loosely hung thereon. This lever carries a pawl 19, which is arranged at its upper end in position to engage a rachet-wheel 20, secured on the shaft 17.
A notched disk 21 is loosely arranged on the shaft 17 This notched disk can be turned and secured in adjusted position by means of a spring-catch 22. Said notched disk has a shoulder 23, which reaches under can be adjusted so that the supply of ink can be regulated. The lower end of the lever 18 is connected by a link 24 to a crank-ar1n 25 on the cam-shaft 16.
The impression-cylinder A has its shafts eccentrically journaled in boxes 26, which are journaled in the framing of the machine." These boxes have extending arms which connect by links 28 to arms 29 secured on shaft 30, journaled in the framing. As said shaft 30 is oscillated, as hereinafter described, the impression-cylinder will be raised and lowered to coact with the bed in the usual mannerthat is, the cylinder will be lowered to make the impression as the bed moves forward and will be lifted to clear the form as the bed makes its backward stroke.
The following mechanism is rovided for I out of operation or thrown into Operation, as
operating the cylinder: Mounte on the shaft 16 is a box-cam 31, the inside line of which is shown. The same engages a roller 32, hung on a vibrating lever 33. Connected to this lever is a link 34, which has a hook at its end. This hook can engage a pin or roll 36, arranged between two arms 37, projecting from a hub secured on said shaft 30. When said hook is in engagement with said pin or roll 36, the impression-cylinder will be raised and lowered in its regular operation. A tripping motion is provided for these connections. This tripping motion consists of the foottreadle 38, mounted on a rod attached to an arm 39, mounted on a shaft 40. This shaft has an arm 41, which connects by link 42 to a cam-block 43, loosely mounted on said shaft 30. Projecting from the hook 35 is a stud 44, which carries a roller 45, arranged in position to engage said cam-block 43. When the foot-treadle is in its normal or raised position, the cam-block 43 stands in the position shown in Figs. 5 and 7, and the hook 35 will engage the pin 36 and oscillate the shaft 30 to put the impression-cylinder through its regular operations. If the foot-treadle is depressed, the cam-piece will be moved to the position shown in Fig. 6. When in this position, as the hook 35 moves to the extreme right-hand position the roller 45 will run up the cam-block 43, which will disengage the hook from the pin 36, so that the arms 37 will be left in their right-hand positions, as
shown in the drawings, so that as the hook 35 moves to the left the same will clear said pin, whereby the impression-cylinder A will be left in its raised position or tripped, although the remaining mechanisms go through their regular movements. The cylinder A will remain in its raised or tripped position so long as the foot-treadle is kept depressed. When the treadle 38 is released, the cam-piece 43 will move back to the position shown in Figs. '5 and 7, whereby when the hook 35 again reaches the right-hand position it will engage the pin 36, and the impression-cylinder will be thrown into operation. The arms 37 are usually extended to bear on a fixed part to define the exact position of the same to the right, and a spring-pressed arm 46 (shown in Fig. 3) is usually arranged in connection with said arms to keep the arms in proper position,
- when the hook 35 is lifted by the cam-block 43 clear of the pin 36 and the impression-cylinder tripped. A stop-piece 47 is usually arranged on the cam-block 43 to limit the motion thereof.
The foregoing constructions comprise a common well-known form of printing-machine. In such constructions when it is desired to stop the inking mechanism the pawl 1 9 is lifted out of engagement with the ratchetwheel, a leaf-spring or some similar device being provided, so 'that the pawl can be kept desired.
The object of the present invention is to add to the foregoing mechanism devices whereby the supply of ink can be controlled by the operator without going to the end of the press, where the ink-fountain is arranged. To accomplish this desirable result, the following connections are arranged: A weighted pawl 470 is arranged on the side of the fountain to prevent the fountain-roll from turning backward. The pawl 19 is given two cam- surfaces 48 and 49. A leaf-spring 50 is secured to the lever 18 to engage a pin 51, carried by the pawl 19. A stop orfiling piece is usually arranged on the arm 18 for said pin 51 to engage to define the thrown-out position of the pawl 19. It will be seen that when the pawl is in operative position, as shown in Fig. 8, said spring 50 Will push on the pin 51 and will cause the pawl to engage the ratchet-wheel 20. The end of the leafspring is turned down, so as to leave a shoulder 500, whereby when the pawl is snapped to inoperative position the pin 51 will pass said shoulder 500, and the spring will then hold the pawl in inoperative position.
To control the action of the pawl the following mechanism is provided: A treadle 53 is arranged on the frame of the machine. The same connects to an arm 54, mounted on a short shaft 55. This shaft has a small lever or arm 56 thereon, which connects by link 57 to a lever 58, mounted onashaft 59,ar-ranged near the ink-fountain. Secured on this shaft 59 is a lever or finger 60, which is arranged in position, to engage and control the pawl 19. When the treadle 53 is in raised or normal position, the finger 60 will stand in the position shown in Fig. 8 and the pawl 19 will operate with the ratchet-wheel in theordinary manner. When it is desired to disconn'ect the inking mechanism, the treadle 53 is depressed. This will move the lever 60 to the position shown in Fig. 1O, so-that when the pawl reaches its extreme backward movement the cam-surface 49 thereof will engage the end of said lever 60, which will-sna the pawl out of operation. The pawl wil remain out of operation until the lever 60 again assumes its normal position, as shown in Fig. 11, when the cam-surface 48 on the pawl 19 will engage the end of the finger 60, and the pawl 19 will thereby be snapped into operation. The parts are shown in Fig. 11, with the cam-surface 48 just engaging the end of the finger-lever and just before the pawl 19 and lever 18 reach the extreme of their movements. When the press is stopped with the pawl 19 in its fullback position, the pawl 19 can be thrown in or out of operation, as desired, by moving the lever 60 to engage the cam- surfaces 48 or 49.
The ink-fountain trip mechanism has no connection or operative .relation with any other part of themachine and is controlled entirely from the treadle 53. The treadle 53 is usually arranged adjacent to the treadle 38, so that, if desired, the operator can simultaneously depress both treadles and throw the inking mechanism out at the same time he trips the operation of the impression-cylinder; but there being no connection or operative relation between the treadles enables the operator to trip either or both mechanisms at will. This is advantageous in the following ways: When the press is first started, it is customary to run the same for a number of strokes with the impression-cylinder tripped and'with the inking mechanism in operation to ink up, as it is called, so that the rollers and form will be fully charged with ink when the sheets are first fed to the machine. To do this operation, the operator simply depresses the treadle 38, which puts the impression-cylinder out of operation, but
leaves the inking mechanism in operation.
In other cases it is desirable to stop the supply of ink for an impression or number of im pressionsas, for example, when ink has been applied too fast from the fountain or on the last few sheets of a run. To do this, the operator simply depresses the treadle 53, which cuts the inking mechanism out of operation, but still leaves the impression-cylinder in operation. In still other cases when it is desired to throw both impression-cylinder and inking mechanism out ofoperation the operator depresses both treadles 38 and 53 with one foot or with both feet, which throws both mechanisms out of operation.
It will be seen, while the two tripping mechanisms can be operated at the same time by the operator, that there is no operative relation between the mechanism for throwing the ink-fountain out of operation what I claim, and desire to secure by Letters Patent, is
1. The combination in a cylinder printingmachine, of an ink-supply device arranged at one end thereof, and comprising movable parts, mechanism for operating the same, a tripping mechanism for stopping the motion of the moving parts, and connections arranged so that the operator can control said tripping mechanism from his ordinary position independently of any of the other mechanisms of the machine.
2. The combination in a cylinder printingmachine, of an ink-fountain arranged at one end thereof, mechanism for operating the ink-fountain roller, a tripping mechanism for disconnectmg sald operating mechanism,
and connections arranged so that the operator can control the tripping mechanism from his ordinary position independently of any other mechanism of the machine.
3. The combination in a cylinder printingmachine, of an ink-fountain arranged at one end thereof, a ratchet-wheel connected to the ink-fountain roller, a vibrating lever carrying a pawl for engaging said ratchet-wheel to turn the ink-fountain roller, a tripping mechanism for said pawl, and connections arranged so that the' operator can control the tripping mechanism from his ordinary position independently of any other mechanism of the machine.
4. The combination in a cylinder printingmachine, of an ink-fountain arranged at one end thereof, a ratchet-wheel secured to turn the ink-fountain roller, a vibrating lever carrying a pawl for engaging said ratchet-wheel, a controlling-finger for throwing said pawl into and out of operative position, and connections extending therefrom so that the operator can control the action of the pawl from his ordinary position.
