9 Claims.

This invention has reference to printing presses and, more particularly, to such types that include means whereby ink double-rolling of the form is effected, and it has for its primary object the provision of a novel attachment whereby such double-rolling may be automatically controlled incident to positive alternating-interruption and actuation of the air-separator and suction-feed mechanism.

More specifically, although not essentially, my invention aims to provide an attachment for automatically controlling the feeder arm-shaft of vertical printing presses associated with the air separator-suction valve means effective to trans fer single sheets to be printed from the pile table to the printing cylinder.

Another object is to provide a novel means for the purpose specified which is adapted for easy operative connection to, or disconnection from, any convenient operating-shaft of the press to which it may be applied.

A further object is the provision of means of the typified character which is the acme of simplicity in construction, economical to manufacture, and capable of ready attachment to all conventional forms of generally known printing presses.

With the stated objects in view and others, as later on apparent, my invention consists of certain novel and useful features in the attachmentconstruction and combinations of its parts as hereinafter described and claimed; while a practical embodiment thereof is illustrated by the accompanying drawings. 1 g

In said drawings:

Fig. 2 is a broken longitudinal section of the feeder arm shaft and my novel control therefor, drawn to a larger scale for the sake of clearness.

Fig. 3 is a fragmentary detail View through the separator-mechanism, taken as indicated by the arrows 33, on Fig. 1.

Fig. 4 is a side view of the control mechanism as actuated from one of the printing press oscillatory shafts.

Fig. 5 is a fragmentary view taken as indicated by the section-indicating line 5-5 on Fig. 4.

Fig. 6 is an end elevation of the attachment.

Fig. 7 is a sectional plan view taken on the plane indicated by the arrows 77 in Fig. 2; and

Fig. 8 is a surface development of a cam device hereinafter fully explained.

Referring more in detail to the drawings, and particularly to Fig. 1, which depicts, somewhat diagrammatically, a portion of a vertical Miehlepress, for example only; the numeral 1 designates the press side frames, 2 the type bed, 3 the impression cylinder, 4 the pile table, 5 a feeder arm, 6 a portion of the separator-frame, 7 another of the feeder-table arms, 8 one of the ink rollers, and 9 the feeder-arm shaft comprehensively; with the control or actuation of the latter my invention is more particularly concerned.

This feeder-arm shaft 9, as best appreciated from Fig. 2, is tubular and fitted internally with a feeder control-rod 10 having a valve 11 proximate one end to control air-separation and. suction by way of a conduit or passage 12, lengthwise to the feeder arm '7, to the separator frame suckers 13 from a suitable hose 14, connecting with a conventional vacuum system, not shown; while a stop 15 is provided for limiting reciprocation of the valve 11 by coaction with a removable abutment. element 16, in accordance with known practice. This feeder-arm shaft 9 is also provided at its outer end with a knob or grasp 17, ordinarily manipulated by hand; to intermittent- 1y actuate the suckers 13; while the numeral 18 designates the known feeder-arm locking means or latch; all of the foregoing constituting no part of the instant improvements but being briefly referred to, in order to give a better understanding as to the location and purpose of my invention.

In accordance with my invention, I attach to the side frame 1, as by'securing means 19, or to any other adjacent portion of the press, proximate the feeder arm control-rod knob or manipulatorgrasp 17, a hanger bracket 20 having an enlargement 21 affording rigid bearing-support for a stub shaft 22, conveniently secured against axial and rotative movement as by a lock-screw 23. On the shaft 22 is freely mounted a drum or grooved-cam 24, the inner end of which is formed with a series of equally-spaced notches or pits 25, with which sequentially co-act a spring-influenced stop or ball catch 26 mounted in the bracket enlargement 21 aforesaid. In the present instance the cam 24 is provided with four equallyspaced circumferentially-arranged .pits 25 in direct alignment with the rises and falls, or high and low points, 27, 28 respectively, of the groove in said cam; see Fig. 8.

Rigidly secured, as by set screws 29, to the outer end of the cam 24 is a ratchet 30, with which operatively-engages a pawl or dog 31, pivotally mounted at 32 to one arm of a bell-crank 33,

held in place axially of the stub shaft 22 by securing means 34. Pivotally coupled by an angularhead to the other arm of the bell-crank 33 is a longitudinally-adjustable connecting-rod 36 the remote end whereof is releasably-connected by a head-piece 37 to an actuator arm 38, releasably clamped to the free end of the deliveryshaft 39for example only-of the printing press. From Figs. 1, 4 and 5, it will be'noted that the actuator arm 38 is secured to the deliveryshaft 39 by means of rod or bolt 40 passed through the axial center of a boss 41 on said arm and screw threaded at 42 into the end of the delivery shaft. It will also be observed that the rod or bolt 40, beyond its head 43 is providedwith'an extension 44 and diametric hole :45 whilethe actuator arm 38 is positively and operativelyconnected to the delivery-shaft end by pins 46 engaging holes 4'7 in the boss 41 aforesaid.

Referring again to the. releasable-connection, it will'be seen the same consists ofa stud'48 secured inthe outerend of the'actuator -arm 38,

on which the head-piece 3'7 of'the adjustable connecting-rod 36 is freely'fulcrumed andh'eld in place by a splitpin 49. Now, it will berea'dily understood that, when desirablethe' split 'pin49 may be withdrawn andthehead-piece 3'7 slipped onto the bolt extension 44 withthe split :pin49 inserted through the diametrichole'45. Whereupon the ratchet 30 and connecting rod 36 will be .rendered inoperative, for a purpose later" on again referred to.

Slidably mounted. in av non-circular orifice 50 in the bracket enlargement 21, in parallelism with the stub-shaft 22,.is a correspondingly-sectioned reciprocable, but non-rotative,'bar 51, having a laterally-divided freely-rotatable roller '52 engaging in the. groove'of the drum cam 24. This bar 51 is formed with a L round-section "extension 53 on which is loosely-pivoted a forkemember 54 shaped at its outer part to snuglyengagethe feeder-control rod grasp 17; said member being restrained in suchposition by means of an'appropriate ball catch 55 carried in an abutment collar 56, clamped in ;.place by aset screw 57.

The ball catch 55, it will be'remarked,'co-'-acts with .one of two, or more, angularly-spaced notches or .pits 58, 58','inithe fork'member hub 59; and it will be readily apparent "that when said member is rotatively-moved Tfrom the operative position'shown; or,to disengage the ballcatch55 from .the pit 58 so that it engages'in the pit 58, the fork member 54will be released from co-actionwithithe controlrodiknob or grasp 17, whereby the latter may be 'manually'manipulated in the known way. .60 isan adjustable union coupling interposedin the connecting-rod ;36whereby the length of the latter may be varied to regulate the throw 'of the'bell-crank 33; as well as to adapt the attachment to diiferingly dimensioned presses.

the arm 38, connecting-rod 36, bell crank33 and pawl 31, whereby said. pawl intermittently turns the drum cam 24 about its axis. Complete rotation of the cam '24 effects reciprocation of the bar 51 twice, which, in turn by means of the fork member '54, similarly reciprocate the feeder conthrol valve rod 10 to effect ink-double rolling intermediate each transfer of a sheet from the pile table by the suckers 13, in a manner well known to those acquainted with the art to which this invention appertains. Disconnection of the

parts

37, 48 and transfer of the former to the extension 44 for retainment thereon by the split pin 49, results in idling'of the ratchet 'means '30 etc.; while movement of the fork member'si as hereinbefore set forth, entirely frees the feeder control mechanism for manual operation.

From the above description it will be apparent that I- have produced a device embodying all the features of advantage pointed out as desirable, and while I have described and claimed a preferred form of said invention; it is to be understood that Ireserve the right to make all changes properly falling within the spirit and scope of the following claims.
