HOWARD M. BARBER, OF STONINGTON, CONNECTICUT, ASSIGNOR TO C. B. COTTREILL & SONS COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.
l INKING MECHANISM FOR PRINTING PRESSES.
Application fil ed May 26, 1923. Serial No. 641,771.
To all whom it may concern:
Be'it known that-I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Inking Mechanism for Printing Presses, of which the following is a specification.
In the old method of adjusting the composition rollers of inking mechanisms, it is necessary to use a wrench at right angles to the adjusting screw in between the roller frames and the ends of the various inking rollers -and cylinders. In many places it is very difiicult, if not impossible, to operate the wrench in the space around the socket and this is especially true where a roller washing device is employed, as practically all of the space between the ends of the various inking rollers and cylinders and the 'roller frame is occupied. v
The object of my invention is to overcome the difliculties above enumerated by providing novel means for radially adjusting the composition rollers, said means including manually operated adjusting shafts carried by the roller socket members with the head ends of the shafts arranged'in convenient position for action with the Wrenchor other operating tool.
A practical embodiment of,.my invention is represented in the accompanying drawings, in which Fig. 1 represents a portion of an inking mechanism in side elevation, with my improvement applied thereto. I
Fig. 2 represents a detail top plan view of the same, showing my improvement applied to both ends of the composition roller shafts.
Fig. 3 represents a detail section taken in the planes of the line III-III of Fig. 2.
Fig. 4 represents a detail section taken in the plane of the line IV-'IV of Fig. 1.
' The usual roller frames of the machine are denoted by 1 and 2. Theink transfer rollers illustrated herein are denoted by 3, 1 and 5, the rollers 3 and 5 being the composition rollers and the roller 4 being an interposed iron roller. The meansfor adjusting the position of each of the composition rollers, in the present instance, is constructed, arranged and operated as follows, it being understood that a, separate means is provided for each end of each of the composition roll- 'er shafts.
from turning by providing the stem with a longitudinal exterior groove. 13 and the socket member with a pin 14 extending into said groove.
A stud 15 is rotatably mounted in the socket member 10 and its shank 16 is screwthreaded into the bore 9 of the stem 8-.of the bearing member, so that the turning of the stud will move the bearing member longitudinally with respect to the socket member.
The socket member 10 is also provided with another longitudinal bore 17 within which is rotatably mounted thev manually operated adjusting shaft 18, which shaft at one end is provided with a gear 19 meshing with a gear 20, fast on the corresponding end of'the rotary stud 15. The other end of the adjusting shaft 18 is shaped to receive any suitable tool for manually rotating the shaft. In the present instance it is provided with a squared end 21 for receiving the socket of a Wrench of well known or approved form (not shown herein).
Means are provided for holding the roller bearing member in its adjusted position, which means in the present instance is shown as engaging the adjusting shaft 18 and comprisesia spring pressed pawl 22- seated in a recess 23 in the socket member 10, the exposed e'nd of'which pawl engages a ratchet 24 fast on the adjusting shaft.
From the above description it will be seen that each roller bearing member may be adjusted to a 'nicety by rotating the adjusting shaft in the one or the other direction and, when the proper adjustment has been obtained, it will be maintained by the pawl and ratchet connection 22, 24. The
adjusting shaft is preferably inclined with respect to therotary stud and roller bearing stem, this arrangement permitting the use 'of small connecting gears between'the shaft and stud and bringing thehead: end -of-the shaft which is to be connected to the operating tool. in proximity to but out of line with the enlarged portion of the roller bearing member and thus facilitating the ready operation of the adjusting shaft. A suitable tool for turi'iingthe adjusting shaft would be a socket Wrench with a universal joint so that the handle of the wrench could be positioned outside the roller frame for-ready manipulation.
, :Itis evident that various changes may be resorted to in the construction, form and ar r'a'ngement of theseveral parts without de parting from the spirit and scope of my inven'tion; hence, I do notwish tobe limited totheparticular embodiment herein shown and described, but
WVhat I claim is l 1.
