4ing drawings, and to letters or gures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in i ink fountains for printing presses, and more particularly job presses.

It has been found dii'icult to regulate the supply of ink to the feed roll, and to conveniently clean the latter, owing to the fact that heretofore the bearings of the feed roll were stationary, or the bottom of the fountain was adjustable.

According to my invention, I arrange the feed roll so that it may beswung on its bearings vaway from the mouth of the fountain, and also provide a detachable connection between the swinging frame carrying the roller and an eccentricy shaft, whereby when the roller is in normal position, and the connection is made, the space for the egress of the ink may beregulated.

Therefore, the object of the invention is to provide means for regulating the supply of ink to the feed rollerand to provide means whereby the feed roller may be `detached from the regula-ting means and thrown upwardly and away from the fountain forrepairs or cleaning.

The inventionV also` relates to the specific details of construction and arrangement of parts which will be hereinafter described, and particularly pointed out in the claims.

In the drawings :.Figure 1 is a perspective viewof my improved fountain. Fig. 2 is a vertical central section of the sam-e. Fig. 3 is a plan view. Fig. 4 is a side elevation, the detachable connection being disengaged and the ink roll thrown up. Fig. 5 is a detail view of the eccentric shaft for adjusting the feed roller.

pawl out of operative position.

1 indicates a fountain, comprising an inclined bottom 2, and sides 2a, each of which is curved at its forward end tov form a seat for the inking roll, when the latter is in operative position, and above the curved portionsv are perforations 4. An ink roll 5, is located in the forward end of the fountain, its shaft 6, being mounted in bearings in depending arms 7 pivotally supported on screws 8, passing through the openings 4, in the sides 2a.

On one end of the shaft 6, is rigidly secured a ratchet wheel 9, which is embraced by the bifurcated arms 10, of an operating lever 11. Mounted in the operating lever is a spring pressed pawl 12, provided with a projection 13, with which a locking dog 14, may engage if it be desired to hold the By this construction, if it be foundnecessary t0 discontinue the feeding of ink from the fountain, the locking dog may be engaged with the pin which will hold the pawl out of contact with the ratchet wheel. It will of course be understood that even though the pawl is disengaged from the ratchet wheel,

the lever may continue to be operated by the usual connections (not shown). The roll 5, is formed at its ends with flanges 17, to form a snug lit in the curved ends of the sides 2a, which prevents the ink oozing out at the end of the fountain. f Each of the arms 7, is provided with av pair of ears 18, and a pin 19, supported in said ears, to provide a means for coupling the detachable means, now to be described. A shaft 20, is mounted in bearings inthe rear of the sides 2a, and under the bottom 2. Near the ends of this shaft are eccentrics 21, which fit in openings 22, in detachable side bars 23, the latter having notches 24 at their forward ends to fit over the pins 19, and between the ears 18. Nuts and washers 25, are fitted over the ends of the shaft 20, to hold the detachable bars 23 in position on the eccentrics. An adjusting lever 26, is secured to the shaft 20, near one end, and it is formed with a curved slot 27, through which passes a screw 28, engaged by a binding nut 29, which binds the adjusting lever against the side of the fountain to hold the In operation, the fountain is clamped to the press by the support and screw 30, and the roll 5, is thrown down on the pivots 8', to engage in the curved seats of the fountain.

a rIhen the detachable connecting bars 28, are

fitted between the ears 18 .and the notches 2a engage over the pins 19. The adjusting lever 26, is now moved, forward or backward, as the case may be which turns the shaft 20, hence by reason of the eccentrics 21, the roll 5, through the medium of the bars 23, is adjusted toward or from the forward end of the inclined bottom, and the ink passage is regulated. This adjustment having been completed, the set screw 29, is screwed up against the lever 26, and holds the parts in position. Now if after operating the press for a while it be found that the ink flows too freely, or is sluggish, the set screw 29 is released and the adjusting lever is turned accordingly, and the ink passage is regulated.

Vhen desiring to clean the roll 5, the bars 23, are raised to disengage the notches 24, from the pins 19, which frees the arms 7*7, and the latter may then be swung upwardly above the fountain 1, as shown in Fig. 4;. When the roll is in this position, it may be conveniently cleaned, and swung again in its operative position, and the connecting bar lowered, when t-he fountain is in condition for further operation.

A fountain constructed according to` my invention is extremely simple, and will save considerable time in cleaning the roll and affords a convenient means for regulatingv the flow of ink without stopping the press.

Having thus described my invention, what I claim is:

1. In an ink fountain, the combination with a stationary inclined bottom, a swinging frame pivotally supported at the end of the fountain, a roll mounted in the swinging frame, detachable elements engaging the frame to hold the roll adjacent the end of the inclined bottom, means including a cam engaging the detachable elements for moving the latter toward or from the end of the fountain to position the roll with reference to the end of the inclined bottom to regulate the passage of ink, and a handle for revolving the cam.

2. In combination, an ink fo-untain formed with curved end portions, a pivotally mounted roll supported on the fountain and provided with end flanges which fit in the curved end portions, and means for adjusting the roll to regulate the passage of ink, said means including eccentrics and connecting bars.

3. In combination, an ink fountain comprising sides having curved ends and a bottom, a pair of hangersv pivoted tothe sides, a roll mounted in the hangers and fitting in the curved portions of the sides, means for intermittently moving the roll, eccentrics mounted on the fountain, bars connecting the eccentrics and the hangers, and an operating device for moving the eccentrics to adjust the position of the roll with reference to the end of the bottom.

4L. In` combination, a fountain comprising sides and a. bottom, a pair of hangers pivotally mounted on the fountain, a roll mounted in the hangers, a pair of detachable side bars connected to the hangers, and means for moving the side bars toward or from the end of the fountain.

5. In combination, an ink fountain, a frame pivotally mounted in the upper part of the fountain, a roll mounted in the frame below the pivotal points thereof, means for adjusting the frame, said means including an eccentric and a detachable connection between the eccentric and the frame, the detachable connection permitting of the frame and roll being swung away from the end of the fountain.

6. In combination, an ink fountain, a pair of arms formed with ears and mounted on the ink fountain, pins extending across the ears, a roll mounted in the arms, a shaft mounted on the fountain and having eccentrics, side bars formed with openings and notches, the eccentrics fitting in the openings and the notches engaging the pins, a lever secured to`the shaft, and means for holding the lever in adjusted position.

7. In combination, an ink fountain, a pair of arms formed with ears and mounted on the ink fountain, pins extending across the ears, a roll mounted in the arms, a shaft mounted on the fountain and having eccentrics, side bars formed with openings and notches, the eccentrics fitting in the openings and the notches engaging the pins, a lever secured to the shaft, said lever having an arcuate slot, a screw passing through the arcuate slot, and a nut engaging the screw to clamp the lever in adjusted position.

8. In combination, an ink fountain, a frame pivotally mounted on the fountain, a shaft and roll mounted in the frame, means between the fountain and the frame for adjusting the latter and the roll, said means including a detachable device for disconnecting the frame to permit it to be swung up-l wardly and away from the end of the fountain, a ratchet wheel mounted on the shaft of the roll, a housing and lever mounted on the shaft, a pawl pivoted in the housing and normally engaging the ratchet wheel, said pawl having a pin and 4dog pivoted to the housing and having a seat, said seat adapted to engage with the pin and hold the pivoted pawl out of engagement with the ratchet wheel.
