MEANS FOR DRIIT ING THE INK-CYLINDER IN PRINTING-PRESSES WITH A CYLINDER INK DEVICE.
Specification of Letters Patent.
Patented Nov. 9, 1915.
Application filed July 7, 1915. Serial No. 38,527.
T 0 all whom it may concern:
Be it known that I, GUs'rAr HJALMAR Lmns'rnoiu, a subject of the King of Sweden, and resident of Engelbrektsgatan 38, Gottenborg, in the Kingdom of Sweden, have invented certain new and useful Improvements in Means for Driving the Ink-Cylinder in Printing-Presses with a Cylinder Ink Device, of which the following is a specifica tion, reference being had thereln to the accompanying drawings.
In printing presses provided with a cylinder ink device the ink cylinder performs, as already known, not only a rotary motion but also an oscillating motion, the stroke length of which can generally be varied. According to this invention the oscillating motion is produced by the rotary motion in such a manner as to permit the extent of the oscillating motion to be easily varied from naught to maximum during the running of the machine. This is obtained by a cam surface being located on the ink roller and which is pressed against an abutment by the roller being actuated by a spring or the like. The cam which is preferably located at one end of the ink roller has at its circumference an elevation causing the ink roller to be moved longitudinally against the action of the said spring. The said elevation slopes toward the longitudinal axis of the ink roller, so that the length of the stroke is varied by the abutment being moved outward toward the circumference of the cam or inward from the same.
The annexed drawings show one form of the invention.
Figure 1 is a front view, partly in section, of the ink cylinder with adjacent parts. Fig. 2 is an end elevation of the machine. Fig. 3 is a section of a portion of the ink cylinder on the line A to B of Fig. 2. Fig. 4: shows the device for adjusting the abutment.
The ink cylinder 2 with its shaft 3 is as usually mounted in the frame 1 of the machine in such a manner as to permit the cylinder to be moved longitudinally. At the open ends of the ink cylinder plates 4 and 5 are fixed by means of screw bolts. Around the shaft 3 the plate 5 is provided with a recess for a spiral spring 8. The same bears with its one end against the plate 5 and with its other end against the hub of a toothed wheel 9 of a toothed gear adapted for producing the rotary motion of the ink roller. On the hub of the toothed wheel 9 there is a. surface 11 hearing against the frame. From the toothed wheel extend axially pins 10 passing through holes in the plate 5, so that the toothed wheel 9 carries with it the ink cylinder 2 without preventing the same from moving longitudinally. As is seen from the drawings, the spring 8 tends to move the ink cylinder.to the right hand side .of Fig. 1. A cam 6 concentric with the cylinder is mounted on the plate 4, the said cam being pressed by the spring 8 against an abutment located in the frame and consisting in the form illustrated on the drawings'of a truckle 12. The cam 6 has at its periphery an elevation which during the rotation of the ink roller causes the same to move to the left hand side against the pressure of the spring 8, so that during the rotation of the roller the oscillating motion of the same is pro duced by the cooperation of spring 8, cam 6 the longitudinal movement of the ink roller thus becomes equal to naught. The said movement reaches its maximum when the truckle bears against the outmost portion of the cam. In order that the elevation of the cam 6 need not be made too big. the portion a of the cam goes in an oblique direction from outside and inward to thevleft hand side of Fig. 3, while a portion 6 located on the opposite side of the shaft goes. in an oblique direction from within and outward to the right hand side. If the truckle 12 is located at c, the displacement of the ink roller thus becomes equal to the distance between a plane at right angles to the shaft and pass- The decrease and the increase respectively of the stroke length of the ink cylinder may be effected during the running of the machine by disposing the truckle 12 nearer to or farther from the circumference of the earn 6. An example of the arrangement for moving the truckle 12 is shown in the drawings. The truckle 12 is mounted on a pivot 13 fixed in a slide 15 by means of a nut 14. The said slide can be moved in a guide of the frame, the saidguide being radial to the shaft of the ink cylinder. In the drawings the guide consists of a groove 19 in the frame 1, two screws 20 passing through the said groove and being inserted into the slide 15 and permitting it to move along the said groove. Further, a screw spindle 16 is pivotally mounted in the frame and prevented by rings 18 on the same from being moved longitudinally. The screw spindle 16 is inserted into the slide 15 and may be turned by means of a sheave 17. By turning the spindle 16 the truckle will thus be moved and located farther out on the cam 6 or near to the center of same, subject to the direction in which the spindle 16 is turned. The circumference of the truckle 12 is preferably spherical, Fig. 4. Instead of the truckle 12 another movable abutment may evidently be used. Likewise another means may be substituted for the spring 8, as for instance a weight actuated lever for pressing the ink cylinder toward the abutment 12.
Having now described} my invention.
' to the axis of the cam surface,
what I claim as new and desire to secure by Letters Patent is:
1. In means for producing the oscillating, longitudinal motion of the ink. cylinder in printing presses with a cylinder inkdevice, the combination of the ink cylinder with a cam surface located on the cylinder and concentric with the same, an abutment for the said cam surface, a spring device pressing the cylinder with the cam surface toward the said abutment, and means for adjusting the said abutment radially with relation. to the cam surface which is oblique toward its center, substantially as described and for the purpose set forth.
2. In means for producing the oscillating, longitudinal motion of 'theink cylinder in printing presses with a cylinder ink device, the combination of the ink cylinder with a cam surface located on the cylinder and concentric with the same, an abutment for the said cam surface, a spring device pressing the cylinder with the cam surface toward thesaid abutment, and means for adjusting the said abutment radially with relation to the cam surface which is oblique toward its center the portion of the cam surface located at its center being at right angles substantially as described and for the purpose set forth.
In Witness whereof, I have hereunto signed my name.
