MAX ROOKSTROH, OF KLEIN-SEDLITZ, GERMANY.
ATTACHMENT FOR PRINTING-PRESSES.
Specification of Letters Patent.
Patented Aug. 25, 1908.
Application led November 14, 1906. Serial No. 343,431.
To all whom it may concern:
Be it known that I, MAX Rooxs'rnon, director, subject of the Kingdom of Saxony, residing at Klein-Sedlitz, Saxony, Germany, have invented certain new and useful Improvements in Attachments for Printing- Presses, of which the following is a specification.
This invention relates to printing presses and more especially to apparatus 1n connection therewith for the purpose of regulating the lateral movements of the ink distributing cylinders and thus eecting a more uniform distribution of the ink; this being effected mainly by arranging upon the shaft of the ink distributing cylinder a bevel wheel whose plane faces are parallel with the axis of this cylinder, and which, by means of a suitable adjustable device, im arts a reciprocatory movement to the in( cylinder.
The accompanying drawings illustrate two alternative constructions of apparatus in accordance with this invention; Figure 1 being a side elevation, partially in section of an ink distributing cylinder which is rotated by the friction of the duct rollers while Figs. 2 and 3 are respectively a top plan and a front view of the same.
Upon the shaft bwhich is rigidly mounted in the frame a, there is rotatably mounted the ink distributing cylinder o which is adapted to be rotated in the usual manner by means of the duct and friction rollers bearing l against it, and to be moved in the direction of its length by means of adjustable mechanism consisting of a bevel wheel d, rotatably mounted upon the stationary shaft t, preferably within the hollow ink distributing cylinder and with its plane faces parallel with the axis thereof, and of a second bevel wheel g which gears with the bevel wheel d and is actuated by the s ur wheel f. The up er face of the bevel w eel d has formed within it a dovetailed groove r wherein there is arranged a slide i which by means of a screw spindle h can be adjusted to any desired distance from the center of the wheel d. One end of a connecting rod l engages a crank-pin k arranged on the upper side of the slide 'i while the other end of the connecting rod is pivoted to a slide m, adapted to move in a groove n in the shaft b. This end of the condistributingV necting rod carries on its upper side an adjustable block o which slides in an annular groove p of the ink distributing cylinder c and carries it along in the axial direction without preventing its rotation.
The apparatus above described operates as follows z-When the press is-at work the inking cylinder c is -rotated by means of the duct and friction rollers bearing against it. The spur-wheel f is likewise put in motion and rotates the bevel wheels g and d which are in engagement with each other. By means of the pin k which participates in the rotation of the wheel d there is imparted to the connecting rod Z a reciprocatory movement, which by means of the block o sliding in the groove p is transmitted to the inking cylinder c, as shown by dotted lines in Fig. 2. By rotating the screw-spindle h the slide t' together with the pin k attached thereto can be adjusted t0 any desired distance from the center of the wheel d and by this means the amount of movement imparted to the connecting rod and the longitudinal displacement of the inking cylinder can be accurately regulated. When the slide t' and the pin lc are exactly in the middle of the bevel wheel d the device above described is rendered inoperative and the inking cylinder executes a rotary movement only.
Having now particularly described and ascertained the nature ot my said invention and in what manner the same is to be performed I declare that what I claim is 1. An attachment for printing presses comprising the combination with a fixed shaft and a rotatable cylinder mounted thereon, said shaft provided with a groove,
of a rotatable member mounted upon a vertical axis journaled in said shaft, a crank pin carried by said member, a slide mounted in said groove, a block engaging with said cylinder, a rod connected with the crank pin, and means for connecting the block and slide to said rod whereby on the rotation of said member a longitudinally reci rocatory movement will be imparted to sai cylinder.
2. An attachment for printing presses comprising the combination with a fixed shaft and a rotatable cylinder mounted thereon, said shaft provided with a groove, of a rotatable member mounted upon a vertical axis journaled in said shaft, an adjustable crank pin carried by said member, a In testimony whereof I have hereunto set slide mounted in said groove, a block engagmy hand in presence of two subscribing wit- 10 ing with said cylinder, a rod connected with nesses.
the crank pin, and means for connecting the block and slide to said rod whereby on the MAX ROCKSTROH' rotation of said member a, longitudinally Witnesses: reoi roeatory movement will be imparted to ULYssns J. BYWATER,
sai cylinder. PAUL ARRAS.
