To all whom it may concern:

Be it known that I, HENRY F. BEoHMAN, a citizen of the 'United States, residing at Battle Creek, in the county of Calhoun and, Michigan, haye invented certain State of new and useful Improvemen'tsin Distributing-Fountain Mechanism; and I. hereby de clare that the following is a full, clear, a'nd exact description thereof reference being had to/jthe accompanying drawings, which form part of this specification.

-This invention is a novel distributing fountain mechanism particularly designed for printing. presses, and especially adapted printing presses.

The objects of the invention are to slmor use in copnection with rotary-cylinder plify the construction, reduce the number of parts, and dispense with the ordinary fountain roll and ductor, and to take ink from v the fountain and deliver it to theform-rollers by one large roller or drum, which drum performs *the functions of the ordinary ductor and distributing ,will be. readilyunderstood by those famil- 1ar with the art and is capable of embodiment in, different formspand ofuse in various types of presses, and in other machines where "iscous fluid is fed from a fountain and has to be distributed before reaching.

thepoint of its application to the material acted upon.

The accompanying drawings 'illustrate' one practical embodiment of the invention, which I will'explain with reference, to such drawings, and the essential features and combinations of parts for which protection is desired are summarized in the claims.

In said drawings I Figure 1 is a sectional view of a fountain, and a diagrammatic viewv of a drum 006perating with the fountain, of a printing couple, and of a system of rollers cooperating with the drum to distribute the ink and supply same to the printing couple.

Fig. 2 is a detail part side View and: part section of Fig. 1.

Referring to Figs. 1' and The fountain 1 may be of any suitable-form, and is prefspecification of Letters Patent.

The drum may be rotated by gearing or i any suitable means (not shown) in the diindicated in Fig. 1, and

takes ink or fluid from the fountain, surplus fluid being'removed from the surface of the drum by means of a suitable scraper blade 3.

As shown in Fig.1 this scraper blade 3 is adjustably attached to a plate or casting 4 Which is secured to one side of the fountain ,by bolts r passing through slots/Pin the plate4; and said plate 4 may be adjusted toward or from the drum 2 by means of bolts rap ed through a lip or flange 1". on the side of the fountain, and bolts 4 may-be locked when adjusted by means of nuts 4:.

The scraper blade 3 may be secured to the plate 4 by means of bolts 3 tapped into plate 4:, washers 3 being preferably interposed between the heads of the bolts 3 and the blade 3. The scraping edge of the blade 8 may be further adjusted relatively to the periphery ofthe drun1'2 by means of thumbscrews 4 which can be adjusted in the usual manner-so as to-regulate the amount of ink on the surface of the drum 2 that can pass the scraper.

Cooperating with the drum 2 exterior to the fountain are a series of Vibrating and l at 5, 5 5?, 5, and 5 One or more of these rollers, as for instance roller 5", may be a vibrating roller; and if desired one or more of these .rollers may be composition rollers. A sufficient number of distributing rollers should be employed and properly operated to thoroughlydisseminate the ink uponthe surface of the drum 2 before it reaches the form-rollers 6, 6 which'formdistributing rollers (five being shown in Fig.

rollers are arranged after-the last distribut- T ing roller, of the series. of distributing.

' The form-rollers 6, 6" contact with the petherefrom, and, in example shown, transfer and receive the ink.

plate cylinder P of a rotary printing couple of any suitable construction. In the example indicated in Fig. l the plate cylinder P is arranged between the impression cylinder I and the drum. 2. In Figs. 3 and II have shown a practical form of construction enibotlying the invention and especially adalpted for ink distributing fountains for printing presses. In this construction however only four ink rollers 5, 5 5*, 5 are employed instead of five as indicated in Fig. 1.. These rollers are supported in brackets 7 attached to castings 7 mounted on the ends of the fountain and which may form or carry the bearings in which the journals 2 of the fountain roll 2 are mounted. The form rollers 6, (5 are slioivn'as mounted in ad- 'justable brackets 7" attached to the castings 7. The particular construction of these brackets and castings are not essentials of the present invention.

In practice the drum 2 plate cylinder P; and for this purpose the plate cylinder P and [the drum 2 may be ,intergeared, in any suitable manner (not shown), so that they will rotate at the same peripheral speed and in the same direction;

so that the form rollers 6, 6 can readily and properly transfer ink from the drum'to the printing surfaces on the plate cylinder. It will be seen that with this construction the drum 2 performs the functions of a fountain roll, a ductor, and a distributing drum.

By this invention as applied to printing presses I dispense with the ordinary fountain roller and the ductor roller, simplify the inking mechanismby lessenlng the number of parts required and the amount of gearing; and render the mechamsm more compact. It also enables a larger supply of ink to be maintained' in the fountain, and causes may be driven at any desired speed. It is preferably drlven at the same-speed as the printing surfaces on aeeaeoe fluid taken by' the drum fromthe fountain.

In testimonyv that I claim the foregoing as my own, I affix myjsignatnra HENRY RBE OHMAN.
