SAMUEL ELDER, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO MIEHLE PRINTING PRESS & MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A COR- IPORATION OF ILLINOIS.
ROLL con'rnon.
Application filed August 27, 1923. Serial No. 659,495.
To all whom it may concern:
Be it known thatI, SAMUEL. ELDER, a citizen ofthe United States, residing at Washington, in the District of Columbia, have invented certaln new and useful Improvements in Roll Controls, of which the following is a specification.
This invention relates to a new and improved rollcontrol for printing presses and more particularly topmeans for disconnecting the roll from its drive mechanism and for retaining it against rotation and 1n a desired rotary position; f 1 1 With certain types of presses as, for ex-v ample, the presses used in printing engraved notes or the like, it is desirable to operate the press for a short time when starting up work or at other times without taking off impressions from the plate. With presses of this type it is necessary to keep a very accurate account of every impression made in order to prevent unauthorized production of notes. This count is usually. kept by means of automatic counting mechanism associated with the impression roll of the press; therefore desirable to provide means for operating the press without rotating this impression roll. 7
It is an object of the present invention to provide impression roll driving mechanism adapted for disconnection from the roll to permit operation of the press without rotating the roll. I
It is a further object to provide means adapted to engage the roll and retain it against rotationin a desired rotary position.
Other and further objects will appear as the description proceeds.
I have illustrated a preferred embodiment of my invention in the accompanying drawmeans.
Referring now to the drawings, the impression roll 11 is provided with the shaft It is 12 carried in supports 13 and 14. These supports are mounted upon the press table 15, the plate carrying board 16 moving under the roll between the guideways l7 and 18 formed in the bed of the table. The supporting roll 19 is journaled in the lower ends of the support members 13 and 14 and is provided with the gear 20- through which it is driven. provided with gear 21 which by means of gears 22 and 23, shown in Figure 3, drives the gear 24 carried upon the outer end of the impression roll shaft 12.
Upon its opposite ends it is As shown in Figure 2, the roll 11 is 'prowhich projects from the end'of the roll 11.
This pin is so located that the link maintains the roll in position with its depressed portion opposite the pressbed as shown in Figure 2. As shown in Figure 3, the support 14 is provided with the pin 33 which serves to limit the downward swinging movement of the link 29 when it is in its disengaged position.
The gear 24 is loosely fitted upon the reduced portion 34 of the shaft 1.2. The arm 35 is clamped by bolts 36 upon the outer reduced portion 37 of-the shaft 12. This arm 35 is provided witha bore 38 in which is fitted the pin 39. This pin is provided with the slot 40 having notches 41 and 42 therein. 7 The detent 43 is pressed by spring 44 into the recess and notches. The gear 24 is provided with a recess or opening 45 therein which is of a size to receive the end in Figure 4. This is permitted by the detent 43 pressing upwardly the s ring 44. At the outer position the detent will drop in notch 41. These notches and the detent are so related as to permit inward or outward movewent when the pin is positively operated, hut to prevent accidental movement. ittter the pin it iiiithclrnwn, the link .29 swung in the counter-elocltwise direction {13 seen in l igture 3 until the notch 31 eiiigniges the pin 12 ei'irrietl hy the roll. It will he necensnry, oi. (:(ilil'rit tor the roll to he in a position in which it is shown in lligure 2, which position is the normal one intermediate two inipi'essions.
With the roll lock in this position, the prone nm he operated lliit any desired purpose. such a? cleaning; zinil oiling, Without the impression roll rotating and without the ]i)Ot-iF 'llllllli of any lli1])10$f l0li$ being); struck o ll lrou' the plates. (lmieeruieutl v the count inn iueclninisni zienocinterl with the roll llQll'l not he operated 21? there in no necessity of eountine movements of the prenn which can not produce impressions from the plates.
To again connect the roll to the driving ii'ieelitliiisiii, it is only necessary to bring the press to such position that the opening in the gear 2 1 coincides with the ponition of the pin 39 and to then thrust this pin into the opening- 45. The link 29 is then unhooh'erl from the pin 32 and swung hack against the pin 33.
While the present invention has been de z -i:il.)etl x1e usecl in commotion with one type oi press, it is ohriously capable of: use with other apparatus and I contemplate such modifications and changes as (301116 within the SCOPE? of the appended claims.
l. claim:
1. in u press, no impression roll, supports for will roll a shaft for the roll, it driven gear looeely litterl on snicl sha t't, means can i'ietl h the shaft adapted to operetively con-- nect the gear to the shaft, and means adapt etl to engage the roll to look it against rolntion.
2. in n prose nu iln 'ireision roll, supports tor eaid roll, a shaft for the roll, a driven ,eienr loosely fittetl on said shaft, menus corrierl in the shaft adapted to operatively connect the gear to the shaft, and a link piv- ()lTGfl, to :1 support and adapted to engage the roll to lock it against rotation.
