The prcsentinvention relates to inkifountains for printingzpressesand hasjforanfob- )ect toprovidea novel structure which will bemore compact. and economical than any Y' heretofore in use. Y Y

In the usual fountain construction, the fountain roll is mounted in a bowlcarried'by a air of hinged arms spring-pressed against a j ustable stops wherebyithespacingbetween the fountain roll and the pick up roll; maybe regulated. Because the bowl is mounted on movable supports, fiexible conduits orfpipes with flexible joints must be provided for feeding the inkthereint'o.V p `It is an ,obj/ect' ofthe resent invention to provide a fixed fountain owlV or basin with a resilient'mounting,-forthe fountain'croll there:

in. By usinga fixed basin, flexible ip es and .fittings may beA dispensed with, there y'reducing expense and overcomingrthe possibility of leakage.

Y Another objectofthe vinvein-tion is-to "form the fixed basin asga'nintegralypartof'the bed plate of the press..

I VSince* th 'fountainnieclianisirin*the two A basins isalike, a descriptionl ofthemeoli anism in 'one of the basinswi11'i l Mountedfin alemaniaadjantetheparef tion'jlandnear opposite endsztliereofaretwo brackets er; finished 'pads esffer thesetreckf.

etslbeing 'provided ontheeeorof metas-in roo Hinged to the brackets is a pair of arms 29 which provide bearings 30 for a fountain roll 31. The free end of each arm bears upon a coil spring 32 which embraces a stud 33 fixed to and rising from the bottom wall 11. The stud passes through an aperture in the arm and is threaded near its upper end to receive a nut 34. The latter serves as a stop to limit the extent to which theroll can be raised. The upper end of the stud is supported in a bracket 35. The fountain roll may be adjusted vertically by turning the nuts 34 and to this end each nut is 'formed with spiral teeth meshing with a spiral pinion 37 fixed to a shaft 38 journaled in the bracket 35. Each shaft 38 is formed with a squared end 39 for the application of Ya wrench. Obviously, by this arrangement a very close adjustment canbe made of the spacing between the fountain roll and a pick up roll 40 mounted thereabove. Y

The fountain :roll is vformed at each end withstuds 41 which pass throughl the bearings 30 and enter pockets 42 formed in the arms29. In each pocket and fixed to the fstud is a gear 43 which meshes/with a pinion 44 (Fig. 3) secured on a drive shaft 45, by which means the fountain roll is driven. Each arm 29 is formed with a bearing face 46 of somewhat larger diameter than the fountain roll but cut awayto clear theY pick up roll. This face is adapted to bear against the adjacent end of the fountain roll, and in order to keep the bearing faces in contact with the roll the arms 29 are laterally adjustable, being provided with set screws 47 which bear against finished surfacesor pads 48 formed on the end walls of the basin. The fountain roll 31- isl providedwith the usual means for controlling the'iilm of ink thereon, such means constitutinga blade 50 carried by a head 51 hinged upon the brackets 27. The usual means 52 are provided for adjusting the blade so as to regulate the thickness of theink lm at any point along the roll. indicated fragmentally in broken lines at31a in Fig. 1. j TheVV operation o f the apparatus needs no explanation because it follows the usual practice except that the bowl or basin is stationary and the fountain roll with the mechanism for regulating 4the ink film is mounted in andl adjustable with respect to the basin. Since the `float chamber is located between the two basins 15 and 16 and communicates directly therewith through 1the ports 20 and 21 all iexible piping is dispensed with and the only piping ynecessary is thatconnecting the fixed section 22 with the source of'ink supply. Y i While I have described av preferred embodiment of my invention,` I wish it to beV .understood that this is to be taken asillustrative and not limitative, and that I am Vfree The fountain roll in the basin 16 is to make such changes in form, construction and arrangement of parts as fall within the spirit and scope of the following claims.

I claim:

13. A bed plate for a printing press formed with a recess adapted to serve as a fountain bowl, a pair of arms mounted in the bowl, means for adjusting the arms vertically` with respect to the bowl, a fountain roll-journalled in the arms, each arm being formed with a bearing face adapted to kbear against the adjacent end of the roll, and a set screw on each arm, the bowl being formed with finished surfaces at each end against which the set screws are adjustable to hold said bearing faces against the ends of the roll.

In testimony whereof, I have signed this specication.
