INK-=FOUNTAIN.

SPECIFIGATIONforming part of Letters Patent No. 277,582, dated May 15, 1888.

Application filed August 7, 1882. (N0 model.)

To all whom it may concern:

Be it known that 1, CHARLES A. LIEB, of the city, county, and State of New York, have invented, made, and applied to use Improvements in the Construction of Ink-Fountains for Use in Printing-Presses and I do hereby declare that the following is a full, clear, and correctdescription of my invention, reference being bad tothe accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which- Figure l is a view of my fountain as appliedto a job printing-press; Fig. 2, a top view of the fountain; Fig. 3, a cross-section of Fig. 2; Fig. 4, a view of the ratchet-wheel and pawl employed by me; Fig. 5, a cross-section of Fig. 4. Figs. 6 and 7 are views of the eccentric sleeves employed.

In the drawings like parts of the invention are indicated by the same letters of reference.

The nature of the present invention consists in improvements, as more fully hereinafter set forth, in the construction of inkingionntains for job printing-presses, and will be found to relate more particularlyto that class of printingpresses in which a revolving disk is used for the distribution of the ink, the object of the invention being the production of an inkingfountain simple in construction, easilycleaned, readily adjusted, and one aiiorded to the consumer at a low cost.

To enable those skilled in the arts to make and use my invention, I will describe its construction and operation.

A shows the trough to receive the ink, provided with an inclined bottom, as shown, and B is the duct-roller of the fountain.

(J shows eccentric sleeves or collars, two of which are used, passed over the journals of theduct-roller B, and received within the slot.- ted ears a on the forward part of the trough A, within which they can be turned. Tliese eccentric sleeves or collars G are provided with the lovers or handles 1), by which their position is regulated.

E are bindingscrews bearing upon the eccentric sleeves or collars G, and holding the same in position. These'screws E are passed through the forward parts of the ears a.

The ductroller B is elongated on one side by continuing the metal of which itis formed, and projects beyond the side line of the trough A. Upon this elongated portion is received a ratchet-wheel, F, provided with a journal, G, passed through an opening in a curved lever, H, near its upper end. A collar, J, and setscrew K keep the ratchet-wheel in position upon this elongated portion.

H shows a curved lever, the lower portion of which is made open to form a cam, M, fitting snugly over the hexagon-nut, asshown in Fig. 1, passed over a stud secured in the back shaftof the printing-press. Within an opening in the lever H the ratchet-wheel F is secured, and directly above the ratchet-wheel is placed the pawl N, by which the ratchet-wheel F 'is operated.

0 are brackets for supporting the fountain in proper position over the ink-disk of the printing-press, so that ink may be taken from the duct-roller of the fountain by one of the composition rollers employed to ink the form, and by it be imparted to the disk.

Such being the construction, the operation will be readily understood. The duct-roller B of the fountain is adjusted to the forward edge of the trough A to give the desired flow of ink from the trough to the duct-roller B by turning the eccentric sleeves or collars G by means of the handles D, and then tightening the regulating-screws E. Thus,ifthe broad portions of the sleeves or collars are brought nearer the front line of the trough A, the roller B is thrown forward or away from the trough A, and the ink will flow freely to the duct-roller B, and vice versa. been supplied with ink from the trough A, is revolved by means of the lever H, the cam end M of which is fitted snugly over thehexagen-nut, as shown, and, as the back shaft of the press turns, causes the pawl N to turn the ratchet-wheel F a certain distance, and as the ratchet-wheel is fixed upon the elongated por tion of the duct-roller B, the turning of the ratchet-wheel by means of the pawl causes the duct-roller to revolve.

It will be seen that while the form-rollers are imparting ink to the form the duct-roller is receiving-its supply of ink from the trough, and revolving so as to present the ink thus re- The duct-rollerB, having I ceived to the upper form-roller as it reaches the extent of its upward movement, so that as the form-roller descends this ink received by it is imparted to the ink-disk and distributed 5 over the disk by the revolution of the same.

Having now set forth my invention, what I claim as new is- The combination of the ink-trough A, the

duct-roller B, the eccentric sleeves or collars O, and the bindingscrews E, constructed and I0 operating substantially as and for the purpose
