CONTROLLING DEYlCE FOR-LIQUlD-S-UPPLY ROLLS.

SPECIFICATION forming part of Letters Iatent No. 742,249, dated October 27, 1903. Application filed February 2 7, 1 gf)h .f Serial No. 145.336. (No model.)

To all whom itdmay con/corn: v

p ing the parts in a difierent position. Be it known that I, 'WILLIAM S A KHA- VER, a citizen of the United States,'residingi at New York, county of Kings, and State of f New York, have invented certain new and{ useful Improvements in Controlling Devices l for Liquid-Supply Rolls, fullydescribed and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in controlling devices for liquid-sup.

ply rolls.

In certain classes of machines itis customary to employ a liquid-supply roll and a ductor or delivery roll which takes the liquid from the supply-roll and delivers it. instance, in the constructions used in planographic-printing machines, and ordinarily known as water-motions, there is employed. a fountain-roll which takes up water from a fountain and a delivery or ductor roll which takes the water from the fountain-roll and delivers it to other rolls, by which it is placed upon the form.

The present invention has for one of its ob.- jects to produce a simple, cheap, and effective construction by which the amount of liquid delivered by devices of the class referred to shall be controlled. V A further object of the invention is to produce an improved construction by which the amount of liquid delivered by devioesof the character above referred to shall be controlled, which construction can. be readily adjusted without stopping. or otherwise interfering with the Operationof the machine.

Thus, for

With these and other objects in view the the frame.

Fig. 4 is a view similar to Fig. 2, but showing the parts in a different adjustment. Figs. 5 and 6 illustrate a modification of the construction shown in Figs. 1 to 4.

Referring to the drawings which illustrate one embodiment of theinvention, 1 indicates the frame of the machine. The liquid-supplying devices may be of any suitable construction. Asshown,they consist of a pan 2, in which rotates the usual supply-roll 3, which is journaled in suitable bearings on The delivery or ductor roll 4 may be mounted in any suitable manner, so as to move between the supply-roll 3- and a roll 5, which is one of the rolls by which the liquid is distributed and delivered to the form. livery or ductor roll 4 is mounted in arms 6, which are rigidly secured to a rock-shaft 7,

'journaled in suitable hearings in the frame.

The mechanism by which the rock-shaft 7 .is operated may be of any suitable character; but as shown it includes'a suitable Operating-cam and a controller, which together effeet the movements of the delivery-roll from In the present construction the dethe supply-roll to the distributing-roll and i which govern the time during which the delivery-roll remains in contact with the supply-roll, and thereforedetermine the amount of liquid taken up by the delivery-roll. In the construction shown this operating-cam is a rotating cam, (marked 30,) said cam being fast on and rotating with a shaft 31,,which is suitably supported in the frame of the machine.

The controller in the preferred construction comprises a block 32, which, as shown,

is pivoted at 3 3 to the cam 30, so that it may be given movements independent of the movement which it has when moving with the cam. The means for giving the controller its independent movement may be varied widely. In thepreferred form of the construction, however, this means will include an adj ustable'cam 34, said cam being loosely mounted on the shaft 31, before referred to.

The controller-block 32 is provided with a.

cam-roll 35,which cooperates with the cam 34. In the operation of the device the cam 34 is stationary with respect to the shaft and the cam 30 and the controller-block revolve with it. The roll 35, running on the cam 34, causes the controller to be given movements the time and extent of which will depend upon the position and contour of the cam 34. The position of the cam 34 may be adjusted in any suitable manner. As shown, this cam is provided with ahub 36, which is surrounded by a hub 37, said hub having a set'screw 37 tapped through it, so that the hubs 36 and 37 are connected thereby. Extending from the hub 37 is an arm 38, provided with a handle 39. By operatingthis handle the cam 34 may be adjusted axially around the shaft 31 in any desired position. Suitable locking means are provided for holding the cam in its adjusted position, and these locking means may be of any suitable character. As shown, the arm 38 carries a bolt 40, which runs in the slot 41 of a sector 42, secured to the frame. 011 the end of this bolt is a tightening-nut 43, by which the arm and handle may be locked in any desired position in the sectorslot.

The means by which the cam and controller operate to effect the movement of the delivery-roll may be varied and will vary according to the location and arrangement of the fountain.

Referring to Figs. 1 to 4, inclusive, in which the fountain is shown as above the distributing-rolls, there is provided an operating-lever 44, which is pivoted at 45 to the frame of the machine. This lever is provided with a bowl or roller 46, which is long enough to run both on the surface of the cam and on the surface of the pivoted con trollenblock This lever 44 in the construction shown is connected, by means of a link 47, to an arm 48, which is fast on the rock-shaft 7, before referred to.

The operation of the construction thus far described will be clearly seen from the illustration in Figs. 2, 3, and 4. Referring to Fig. 2, the cam 30 and the controller-block are in such position with respect to the cam 34 that the roll 35 is about to drop from the raised portion of the cam 34. In Fig. 4 the roll 35 has passed olf the raised portion of the cam 34, and it will be seen that the controller-block 32 has moved inward, it being guided-in its movement and the extent of the movement being determined in any suitable manneras, for instance, by means of a pin 49, which cotiperates with a slot in the l)lockand this inward movement has allowed the lever 44 to descend and rock the shaft 7, thus moving the roll 4 away from the supply-roll 3. As the cam 30 continues to rotate the lever 44 will be allowed to rock downward still farther, so that the roll 4 will be brought into contact with the distributingroll 5. When the. construction is adjusted as shown in Figs. 2 and 3, the roll 4 will remain in contact with the roll 3 for a comparatively short time, and therefore will take up but little liquid.

If, however, it is desired to increase the time of contact between the rolls 4 and 3, the arm 38 is thrown over by its handle 39, thus carrying the cam 34 axially about the shaft 31. Such an adjusted position is shown in Fig. 4. In this figure the cam 34 is so adjusted that its high portion will act on the controller-block 35 at the time the arm 44 has been raised by the high portion of the cam 30. In other words, in this figure after the high portion of the cam 30 has raised the arm 44 into a position where the roll 4 is nearly in contact with the roll 3 the controller-block comes into operation and raises the arm 44 still farther, so as to bring the roll 4 into full contact with the roll 3. At this time the roll 35 of the controller-block hasjust begun to run on the high concentric portion of the cam 34, and during the time when it is passing over this portion the controller-block will remain raised, so that the roll 4 will remain for a much longer time in contact with the roll 3 than in the case of the adjustment before described, and so will take up more liquid.

In the construction shown in Figs. 5 and 6 the fountain 2 and the supply-roll 3 are located below the distributing-rolls 5. In this case the operating connections are somewhat diiferent. The arm 48, which extends from the rock-shaft 7, has connected to it a slide 51, which is guided in its movement by means of a pin 52, mounted on an arm 53, extending from the frame, said pin cooperating with a slot 54 in the slide 51. The lower end of the slide is provided with a bowl 55, which is operated upon by the cam 30 and the controllerblock. In the construction illustrated in Figs. 1 to 4 the variations in the time of contact between the rolls 4 and 5 took place when the roll 4 was raisedthat is to say, after it had been operated upon by the high portion of the cam 30--whereas in the present construction the variations in the time of contact take place when the roll is lowered or after it has been operated upon by the low portion of the cam 80. The cam 30 is accordingly given a somewhat different shape, and the controllerblock instead of being moved toward the center of rotation of the cam 30 to interrupt the contact between the rolls 3 and 4 is moved away from the center of rotation to accomplish the same result. This also necessitates a difference in the configuration of the cam 34.

Referring toFig. .6, it will be seen that the bowl 55 has run oif the high portion of the cam 30, and therefore that the slide 51 has been permitted to drop, so that the roll 4 rests upon the roll 3. In the position of the parts shown in Fig. 6, however, the controllerblock 32 is about to run onto the high portion of the cam 34, so that the controller-block will be raised and will strike the bowl 55, raising the slide 51 and interrupting the contact between the rolls. If, however, it is desired to increase the time of contact between the rolls 3 and 4, the handle will be shifted, as in the construction formerly de- IFO scribed, carrying the cam 34 to the left of the observer as the construction appears in Fig. 6. The farther the cam is adjusted to the left the longer it will be after the roll 55 has run off the high portion of the cam 30 before it will be struck by the controller-block, so that the longer the time will be during which the rolls 3 and 4 are in contact.

While the constructions which have been heretofore described constitute the preferred forms of carrying the invention into effect, it will be understood that many changes and variations may be made therein without departing from the invention; The invention is not to be limited, therefore, to the specific constructions herein shown and described.
