F. STEINMETZ PRINTING PRESS Aug. 17, 1937.

Filed OCT.. 16, 1936 INVENTOR FRITZ STEINMETZ ATTORNEYS PatentedAug. 17, 1937 'Y UNITED s'ra'rlas PATENT OFFICE PRINTING PRESS Fritz Steinmetz, Leiiilll. Germany Application October 16, 1936. Serial No. 105,952 In Germany August 31, 1935 2 Claims.

'Ihis invention appertains to a novel adjusting mechanism for printing presses, and more particular to adjusting mechanism for the ink fountain and rollers of printing presses` utilizing aniline inks.

Heretofore these presses were of anA exceedingly expensive order due to the complicated mechanism employed for adjusting the ink fountain and associate rolls. It was thought necessary to l0 provide individual supports and adjustment on each side of the press for'the ink and distributing rollers. Not only was the adjusting and supporting mechanism expensive, but adjustment was difficult, and undue wear occurred on the various Another salient object of my invention is to provide a mechanism of the above character,

which will be easy to adjust, and in which the various rollers will be heldin proper line.

A further important object of my invention is I to provide an adjusting mechanism, in which wear will be reduced to a minimum, and in which wear can be compensated for by the accurate adjustment of the parts.

- With these and other objects in view, the inj vention consists in the novel construction, ar-

rangement and formation of parts, as will` be hereinafter more specifically described, claimed,

and illustrated in the accompanying drawing, in

' which. drawing:

Figure 1 is a fragmentary top plan view of a 4o press embodying my novel mechanismu lFigure 2 is a fragmentary side elevation of the Figure 3 is a detailed vertical section taken on the line 3-3 of Figure 2, looking in the direction of the arrows.

Figure 4 is a similar section taken on the line 4*-4 of Figure 2, looking in they direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate correspending parts throughout the several views, the letter P generally indicates a printing press, which includes side frame plates 5. 'I'he press is of substantially the usual character, and, therefore, only suilicient parts thereof have been mechanism for supporting and adjusting the (ci. loi-351) illustrated to show the operation of my novel mechanism. As illustrated, the frame plates 5 carry the upstanding arms 6, in which is journaled the shaft 1 for the impression cylinder 8. Normally, bearing against the impression cylinder is the plate cylinder 9, and this cylinderin turn has normally bearing against the same the distributing roller i0. The distributing roller I0 is supplied with ink from the fountain Il by means of the fountain roller I2. 10

These rollersare driven in some appropriate manner, which'forms no part of the present invention. A

My present invention appertains to a novel 15 plate cylinder 8, the distributing roller I0, and the fountain roller I2. The frame plates 5 are provided with longitudinally extending slots I3l and the inner faces. of the frame plates are planed smooth adjacent ,to the slots. If preferred 20 the upper and lower walls of the slots I3 can be rabbeted, as at I4, for a purpose which will be later set forth.

Arranged againstthe polished inner faces of the frame plates 5 are the supporting slide plates 25 I6. The inner face ofthe slide plates I5 havel formed thereon longitudinally extending ribs I6, which are tted within the slots I3, and these ribs have connected thereto by means of screws I1, or similar fastening elements, bearing plates I3, which engage the outer face of the frame plates 5. By this construction and arrangement of partaV the slide plates I5 are firmly held against lateral shifting movement, and are prevented from twisting in any way. At the same time, the slide plates can be adjusted in the slots I3 toward and away from the impression cylinder 8.

In order to provide an additional support for the sliding plates, the same can be provided with 40 longitudinal "shoulders i9, which can t snugly against the rabbets I4. VThe forward upper ends of the slide plates I5 carry suitable bearings 20 for the shaft 2| of the plate cylinder 9, and the plates I5 below the plate cylinder also carry suit- 45 able bearings for the shaft 22 of the fountain roller I2. The fountain II is also connected directly to the slide plates by the use of suitable supporting arms 23. f'

Rockably mounted upon the shaft 22 are levers 50 or links 24, the outer ends of which have pivotally connected -thereto forwardlyr extending links 25. The links 25 carry suitable bearings for the shaft 26 of the distributing roller I0.

By adjusting the slideV plates, all of vthe rollers 55 9, III, and I2, and the fountain II, can be moved toward and away from the impression cylinder.

Any appropriate mechanism can be employed for adjusting thev slide plates I5, and in the pres- 5 ent instance I have shown an'adjusting screw 21 rotatably carried by a side frame plate 5. The

x screw 21 is held against longitudinal movement by a collar 28, and the operating handle 29 which is keyed or otherwise secured to the screw. The

screw extends into an internally threaded 'bore 30 formed in a slide plate I5.

Obviously, when wear takes place on the slide plates I5, or on the frame plates 5, such wear can be taken up by suitable adjustment of the set screws l1.

The distributing roller can be adjusted toward and away from the plate cylinder l by the use of an adjusting screw 3|. This adjusting screw is rotatably carried by a sleeve 42 rockably mounted on a lever 24. Longitudinal movement of the screw 3l relative to its sleeve is prevented by a collar 33, and the operating handle 34 engaging the opposite ends of said sleeve. The

lower end of the screw 3| is threaded into a stub shaft 35 movably carried by a frame plate 5. By adjusting' the screw' 34 the

levers

24 and 25 will be raised and lowered, and as the lever 24 swings about its axis 22, the roller I II can be swung toward andaway from the plate cylinder l.'

v To bring about the adjustment of the distributing roller III, relative to the fountain roller I2, an adjusting screw 36 is provided. 'Ihe lower end of the screw is threaded into a suitable opening formed in a lip 31 carried by the lever 24.

35 This adjusting screw 38 is rotatably received within a sleeve 38 carried by or formed on the upper lever or link 25. 'I'he operating handle 39 for the screw I6 bears against -theupper end of the sleeve 38, and an expansion coil spring 4|I 40 is placed around said screw and normally bears against the lip I'I and a shoulder`l on the sleeve 38. Obviously, b y tightening or loosening the screw the distributing roller Il can be raised or lowered.

From the foregoing description it can be seen that I have provided an exceptionally simple and durable mechanism for bringing about the accurate adjustment of an inkfountain and its associate rolls of a printing press.

Changes in details may be made without departing from the spirit or scope of my invention, but what I claim as new is:

1. In a printing press. a side frame plate,wan impression cylinder rotatably carried byl'the frame plate, a slide plate, means foradjusting the slide plate toward and away from the impression cylinder, a plate cylinder rotatably supported by the slide plate and adapted to'normally engage the impression cylinder; ink fountain supported by the slide plate, a fountain roller rotatably mounted on the slide plate, a link rockably mounted on the supporting shaft for the frame plate, a slide plate, means for adjusting the slide plate toward and away from the impression cylinder, a plate cylinder rotatably supported by the slide plate and adapted to normally engage the impression cylinder, an ink fountain supported by the slide plate, a fountain roller rotatably mounted on the slide plate, a distributing roller mounted between the fountain roller and plate cylinder and adapted to normally engage the fountain roller and plate cylinder, a pair of toggle links connecting the distributing roller with the slide plate, .means for supporting the links of the toggle at their points of connection, means for raising and lowering the support, and means for adjusting one of said links independent of the support.
