7 Claims.

The invention relates to new and useful improvements in printing press inking mechanisms and more particularly to such improvements in the construction and mounting of ink fountains.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being I realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

of the drawings:

Fig. 1 is a transverse vertical section through an ink fountain mechanism embodying the invention;

Fig. 2 is a full elevation looking at Fig. 1 from the right;

Fig. 3 is a horizontal section on line 3-3 of Fig. 1;

Fig. 4 is a full section on lines 4-4 of Figs. 2 and 3, showing the fountain in operating and in withdrawing position;

Fig. 5 is an enlarged fragmentary detail on line 5--5 of Fig. 3.

Objects of the invention are to provide an ink fountain mechanism which is of simple and sturdy construction, of few and simple parts, which are likewise simple and easy to manipulate; and wherein the fountain itself is readily removable for cleaning or substitution of colors,

' or other purpose, and is as readily replaceable in position; which is easily and accurately positionable and is firmly held in position. The invention is directed to improvements in fountains wherein the fountain roller is journaled in permanent position in the press frame, the fountain roller knife blade, and cooperating parts are also mounted directly in the press frame, while the fountain itself is readily insertible and removable, may be quickly and readily removed and replaced without disturbing the fountain roller or knife, and the fountain passes easily, accurately and reliably into its proper positional relation with respect to the roller and the knife. The invention is in certain respects an improvement on that described and claimed in Patent Number 2,166,631, dated July 18, 1939, to Frank A. Foster. The present invention is directed mainly to providing a removable and replaceable fountain-that is wieldy and fairly light, and yet of strong and firm construction, which can be directly and immediately withdrawn and re- 5 placed, positioned and supported in its proper position, and to provide supporting means which are simple, of few parts, inexpensive to manufacture, and simple and easy in operation.

- Referring now in detail to the embodiment of 10 the invention illustrated by way of example in the accompanying drawings, two cylindrical sleeves I and 2 are fixedly mounted, respectively,

in thetwo side frames 3 and 4 of the press, the exterior ends of the sleeves having respective 15 flanges 5 and 6, which abut against the exterior faces of bosses in the press frames and are held in position by screw bolts 1, the cylindrical sleeves extending inwardly some distance within the press frames. The fountain roller shaft I2 :0 is journaled in a plurality of bushings I3 fitted within the sleeves I and 2 at either end thereof, the fountain roller I4 being fixed centrally on its shaft between-the inner ends of the two bushings I and 2. Suitable seals II may be used to pre- 26 vent ink entering the shaft bearings.

The embodied form of removable and reversible fountain comprises a fountain 2I having side walls 22 and 23 of substantial thickness, the side walls having integral, inwardly-extending flanges 30 24 and 25, and the body 26 of the fountain, which may be of sheet metal, is supported by the flanges, the edges of the sheet 26 abutting on the side walls 22 and 23. The rear part of the top of the fountain is provided with a closure plate 35 21, fastened in place by screws 28, this plate closing the top of the fountain from the rear end up to the supporting bar for the fountain roller knife. The side walls 22 and 23 have deep U- shaped recesses 3i formed therein to receive the 40 sleeves I and 2, as the fountain is passed up from beneath into operating position, the edges of these recesses fitting tightly about the sleeves.

The means for positioning andholding the fountain firmly and accurately in position while 45 permitting its quick removal and reinsertion of the same or another fountain, comprise supporting plates 36 and 31, having, respectively, flange hubs 38 and 39 encircling the sleeves I and 2, the supporting plates being disposed vertically 50 at right angles to their hubs. The supporting plates each have bolt-receiving slots 4I and 42 opening on the bottom side of the plates and extending upwardly. Into each of the side walls 22 and 23 of the fountain are screw-threaded ,lifted upwardly from the full line position shown in Fig. 4, into operating about the fountain roller, as shown in broken lines in Fig. 4, and as shown in Figs. 1 and 2, the sleeves l and 2 pass into the recesses ll, and the bolts 43 and 44 enter the corresponding slots ll and 42. The bolts then are turned home to firmly fasten the positioned fountain to the supporting plates. -The plates 36 and 81 may be held in position longitudinally of the sleeves l' and 2 by clamping bolts 48 and 49.

Referring now to the means for regulating the ink supply from the fountain roller, 'an angled roller knife supporting bar 50 is mounted upon and extends across between the vertical press frames. As embodied, this bar has a horizontal flange Bi .and a vertical flange 52, connected at their ends respectively, to two integral transverse end plates 53 and 54, which abut on and fit between pads 55 and 56 formed on the inner faces of the vertical press frames 3 and 4 (Fig. 2), the knife-supporting bar being fixed to the frames by bolts 85. The fountain roller knife plate 51 is mounted between the under side of the flange 5| and an underneath holding bar 58, and these 'parts are fastened together by screws 59. A

series 01'. thumb screw bolts 60 are screw threaded into the supporting bar and bear upon the knife plate 51 to regulate the ink on the fountain roller I4 in the usual manner. The upper surfaces of the fountain-supporting plates 36 and 31 abut against the bottom surface of the horizontal flange 5| of. the knife support, thereby preventing the supporting plates from rotating on the sleeves l and 2, and holding them in alined position to receive the bolts 43 and 44. An ink drum 64 is shown more or less conventionally, and likewise a ductor roller 65 which vibrates between the fountain roller l4 and the ink drum 64. The ductor roller is mounted on arms 66, fixed on a shaft 61. Suitable means for rotating the fountain roller will be provided and as here shown, a driven sprocket 68 is mounted on an end of the fountain roller shaft l2, and is held on by a disc 69 keyed to the shaft and held from axial displacement by a set screw 10. A suitable spring pin clutch 11 is shown between the hub 69 and the sprocket wheel 88. Any suitable means for actuating the .ductor roller will be provided and a part of said means is more or less conventionally shown as a cam 13, keyed on the opposite end of the fountain roller shaft l2, and keyed also on said shaft is a vibrator cam 14, which is part of the means for vibrating the ink drum or other part of the inking system. Suitable means for rotating the ink drum (not shown) will be provided.

The invention in its broader aspects is not limited to the specific mechanisms shown and vdescribed but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
