UNITED STATES PATENT OFFICE.
GEOBG BORNSCHEIN, OF BAUTZEN, GERMANY, ASSIGNOR 'I'O BAUTZNER INDUSTRIE- WEEK A. G., OF BAUTZEN, GERMANY.
FEED GEAR FOR THE CYLINDERS F PRINTING MACHINES.
Application filed July 14, 1922. Serial No. 575,004.
To all whom it may concern:
Be it known that I, Gnono BORNSCHEIN, a citizen of Germany, residing at Bautzen, Germany, 16 Moltkestrasse, have invented 6 certain new and useful Improvements in Food Gears for the Cylinders of Printing Machines, of which the following is a specification.
This invention relates to a feed gear for i the cylinders of printing machines. The feed gears serve to adjust the cylinder bearings of printing machines. The ad ustment has been effected hitherto either by adjust ing screws alone or in combination with an F eccentric bush. In order to enable the adjusting by means of adjusting screws the bearings had slit holes, prismatic guides or pivot pins in which or around which the adjusting Was effected with the aid of the adjusting screws and of spanners. As however the cylinders to be adjusted are close together and situated frequently at places which are not easily accessible the adjustment is difficult and requires much time. The adjusting is rendered specially diflicult as the bearings have to be adjusted in two different directions and consequently two different adjusting screws are required, as each cylinder is in contact with two other 30 cylinders and must be adjusted with regard to both.
According to this invention all adjusting screws as well as the prismatic guides, slit holes and pivot pins are depressed. The adjusting of the cylinders is carried out by hand without the aid of a spanner or of any other power transmitting means, merely by rotation of two eccentric bushes arranged the one in the other. -By means of such a device it is possible to adjust the cylinders very accurately as the resistance produced, if two cylinders come in contact, is immediately perceived in the hand. This adjustin device permits the adjusting of the cy inders in any direction along astraight path as well as along a curved path.
A preferred form of execution of the invention is shown by way of example on the accompanying drawing, wherein i Fig. 1 shows the device in front view, and
Fig. 2 in longitudinal section.
Fig. 3 is a view from below of the inner adjusting bush, partly in longitudinal section.
In the wall 1 of the frame of the printing machine a bush 2 is mounted which has a cylindrical outer surface and a partly conical boring. The wall of bush 2 has a longi tudinal slit 3 at its thickest part. This slit must extend at least over the length of the conical part 4 of the boring. In bush 2 a bush 5 is inserted which has an outer surface partly cylindrical and partly conical and an eccentric boring. The cylindrical end of this bush is externally threaded and a nut 6,with handle is screwed upon the threaded end.
In bush 5 the bolt 7 is located one end of which engages with the-ball bearing 13 of cylinder 8. Upon the other end of bolt 7 a sleeve 9 is mounted so that it can be displaced against the action of a spring 12. Sleeve 9 has a flange like a flanged nut. A nose-1O arranged upon sleeve 9 engages with a notch 11 of bush 5. The bush 5 pates therefore, as long as nose is in engagement with notch 11, in any rotation which is communicated to bolt 7 b the sleeve 9. If however sleeve 9 is pulled back against the action of sprin 12 so that nose 10 gets out of notch 11, only bolt 7 participates in the rotation of sleeve 9 with which said bolt is connected by a connecting pin. If sleeve 9 is rotated anti-clockwise, a stop 17 of bolt 7 is moved in a bayonet slit of the inner bush 5 so that bolt 7 can be re moved from the bearing 13 in its extreme left hand position. A flanged nut 14 is rigidly connected with bush 2.
If cylinder 8 has to be adjusted sleeve 9 is loosened, whereupon the bushes 2 and 5 are rotated with the aid of flanged nut 14; until cylinder 8 is in contact with suflicient pressure with the cylinders with which it works together.
Nut 6 is screwed home again whereby the conical part 4 of bush 5 is pressed into the conical part of the boring of bush 2, this slit bush 2 being thus locked in wall 1.
If the cylinder 8 has to be removed nose 10 is disengaged from notch 11 through sleeve 9 being pulled back, whereupon bolt 7 is turned by means of sleeve 9 as far as the bayonet slit permits and pulled out, so that it releases the cylinder 8 which bears upon seat 16. The cylinder 8 can now be withdrawn.
The insertion of the cylinder is efl'ected in the same manner, the manipulations .being repeated in inverse succession.
partiei- I claim A device of the character described for the cylinders of printing machines comprising in combination with the cylinder mounted on ball bearings, an outer slit hush with cylindrical outer surface and with a boring Which is partly cylindrical and partly conical, an inner bush in said outer bush the outer surface of which is partly cylindrical and partly conical and which has an eccentric boring, an externally threaded outer end, and a nut in its outer end face, a nut with handle screwed upon this outer threaded end of the inner bush, a bolt in the boring of the inner bush engaging with the ball bearing of the c linder, a spring controlled sleeve movabl y mounted upon the outer end of said bolt, a nose projecting from the inner end of said sleeve adapted to engage with the notch in the outer end of the inner bush and a stop upon the inner end of said bolt, engaging with said slit of the inner, bush, substantially as described and shown and for the purpose set forth.
In testimon whereof I afiix my signature in presence 0 two witnesses.
