FOUNTAIN ATTACHMENT.

' Application filed February 18, 1921. Serial N0. 446,153.

To all whom it may concern: 1

Be it known that 1, Louis 1?; Vain, tl Clt1- Zen of the United States, residing at 2011 Congress St, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Fountain .Prttachment, of which the following is a specification. I

This invention relates to printingpresses in which inkis supplied to the form rollers lo a: roller 0 cratin in con'unction with an ink fountain, and the invention has for its object to provide a novel and improved means for adjusting the fountainto vary the position of the fountain roller relative to the form roller for the purpose of obtaining any desired degree of contact between said rollers according to the character of the work to be done by the press. The fountain is adjustableto obtain a greater or lesser degree of contact between the rollers, thereby varying the feed of ink, and the device is so constructed and arranged that the adjustment can be readily made with out stopping the press.

The invention also has for its object to provide a device of the character described which is very simple, and which can be readily applied without any changes in the construction of the fountain or any other parts of the press.

With the objects stated in view, the invention consists in a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification, wherein- Figure 1 is a side elevation showing the application of the invention;

Fig. 2 is a rear elevation, and

Fig. 3 is a side elevation, partly in section.

Referring specifically to the drawing, 5 denotes the ink-containing fountain of a printing press, the same being supported. at its ends by seating on bracket arms 6 of the press frame. The arms 6 are slotted longitudinally, as shown at 7, andthe ends of the fountain carry depending studs or bolts 8 which pass through the slots of the arms, said studs having heads 9 which are located beneath the arms, with a washer 1O interposed therebetween. The studs are fastened to the fountain by being tapped thereinto adjacent to the ends thereof.

The head 9 of each stud 8 has a threaded transverse aperture through which is screwed an adjusting screw 11 having its forward end in contact with a stationary abutment which may be a 'downturned portion 12 of the arm 6. The other end of the screw is formed with a finger piece 13 to facilitate manipulation. v

Onthe under side of each arm 6 is also mounted a holder for the screw 11, said holder being a bar 14 having upturned end portions 15 which seat in the slot 7 and have apertures 18 through which the screw loosely passes, the head 9 being positioned between the parts 15. c b At 19 is shown one. of the form rollers whichcoi'nes in contact withv the roller 20 associatecl vith the fountain 5 to receive a supply ofink. The adjustability of the fountain 5 by means of the screws 11 permits the fountain roller 20 to be properly positioned for engagement by the form roller 19. Adjustment can be readily made to obtain any desired degree of contact by turning the screws 11 to advance or to retract the fountain, and this can be done while the press is running. The fountain roller can also be positioned angularly with respect to the form roller by advancing or retracting one end of the fountain more than the other end, if it is desired that only a portion of the fountain roller is to come into contact with the form roller. If the fountain roller is to come in Contact with theform roller throughout its entire length, it will be necessary to advance or retract both ends of the fountain uniformly. The fountain can also be run back out of service when no ink is required, and this can also be done while the press is in motion.

In order to lock the screw 11 after adjustment is made, a lock nut 21 may be provided, the same being adjustable on the screw so that it may be jammed against one side of the head 9.

Inasmuch as the ends 15 of the holders 14L seatin the slots 7, the holders are prevented from swinging in a lateral direction to carry the screws 11 away from the abutments 12, which would release the fountain 5 and allow it to slide down or drop off the supports 6. The slots 7 run parallel to the direction in which the fountain moves when it is adjusted, and hence they hold the screws 11 properly alined to effect an accurate adjustmentv The washer 10 is sufficiently loose to enable the fountain to be easily moved.

I claim:

1. The combination with a printing pressink-fountain and a support on which the fountain is adjustable; of studsextending from the fountain at the ends thereof and having screw-threaded transverse apertures, adjusting screws threaded through said apertures, and means for locking the studs on the adjusting screws.

2. The combination with a printing press ink-fountain and a support on which the fountain is adjustable, said support being slotted; of studs extending from the fountain at the ends thereof and passing through the slots of the support, said studs having screw-threaded apertures, adjusting screws threaded through said'apertures, and guides through which the adjusting screws pass, said guides seating in the aforesaid slots.

3. The combination with a printing press inlrfountain and a support on which the fountain is adjustable, said support being slotted; of studs extending from the fountain at the ends thereof and having heads which are provided with screw-threaded transverse apertures, and adjusting screws threaded through said apertures.

4;. The combination with a printing press ink-fountain and a support on which the fountain is adjustable, said support being slotted; of studs extendingfrom the fountain at the ends thereof and having heads which are provided with screw-tl1rea :led transverse apertures, adjusting screws threaded through said apertures, and means for locking the studs on the adjusting screws.

5. The combination with a printing press ink-fountain and a support on which the fountain is adjustable, said support being slotted; of studs extending from the fountain at the ends thereof and having heads which are provided with screw-threaded transverse apertures, adjusting screws threaded through said apertures, and stationary abutments against which the screw ends bear.

6. The combination with a printing press ink fountain and a support on which the fountainis adjustable, said support being slotted; of studs extending from the fountain at the ends thereof and having heads which are provided with screw-threaded transverse apertures, adjusting screws threaded through said apertures, and guides through which the adjusting screws pass.

In witness whereof, I hereunto subscribe my name this 15th day of February, 1921.
