lNK=FOUNTAlN FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 390,994, dated October 9, 1888.

Application filed November 2, 1887. Serial No. 254,225. (No model.)

.To aZZ whom it may concern.-

Be it known that I, HADWEN SWAIN, a citizen of the United States, residing at San Fran cisco, in the county of San Francisco, State of California, have invented certain new and useful Improvements in Ink-Fountains for Printing-Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an ink fountain suitable for job-presses, and belongs to the class which are placed in front of theink plate or disk.

In the drawings, Figure 1 shows the attachment to the press. Fig. 2 is a back elevation. Fig. 3 is the side elevation.

The ink-fountain Ais pivoted to the bracket 13, and its forward end is supported by arm D, resting on the flat base of the bracket, and the fountain A is free to rise or fall. Through the ink-roll E the shaft Kpasses. On the end of shaft K is arm D, the lower end of which .rests against the flat bottom of bracket B. The

arm D is so hung thatwhen itis pulled backward it allows the front end of fountain A to fall. Pivoted to the lower end of arm D by the pin I is the slotted arm L. In the slot of the latter the pin P works. This pin is fastened to the upperpart ofthe lug of the side saddle, N, and the saddle, during its backward and forward motion, causes pin I to come in contact with each end of the slot in slotted armL, which is of a suitable length to give a slight front and back motion to said arm. This in turn moves arm D and causes fountain A to rise when the ink-rollers are going up and to fall clear to allow them to pass down. Alug, R, projecting from the side face of the bracket B, engages the arm D when moved forward to prevent the same being pushed too far or slightly beyond a perpendicular line and hold the fountain in position, so that in the downward pressure, as when the ink -rollers are over the roll E and the pin 1 is at the other end of the slot 0, its foot will be held from slipping to the left-,or in the opposite direction.

operated by screws H, regulates the flow of ink.

Having thus described my invention, I claim 1. A fountain located in front of the ink plate and supportedin the bracket B, in combination with the raising and lowering arm D, mounted on its shaft and with its lower end resting upon and supported by the foot of the bracket, substantially as described.

2. An ink-fountain, A, having the ratchetwheel mounted upon its shaft, said fountain being supported in the bracket B,the rai singand lowering arm D, also mounted upon the fountain shaft, the lever I- for moving the arm, and the pawl mounted on the bracket to engage the ratchet-wheel and revolve the roller in the movement of the arm, substantially as described.

3. The combination of the fountain, the arm D, and theslotted lever L, connected to the arm and the side saddle of the press, substantially as described.

4. The combination of the rising and falling fountain A, arranged in front of the ink-plate, the arm D, mounted upon its shaft, and the slotted lever L, connected with the pin 1? on the side saddle, and from which motion isim parted to the lever, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

HAD SWAIN.
