COUNTING ATTACHMENT FOR PRINTING PRESSES.

Application filed June 23, 1922. ,Serial at. 570,486.

To all whom it may concern. i

Be it known that I, JOHN DAVID H NT, a subject of the King of Great Britain, of the city of Toronto, county of York, Province 5 of Ontario, Canada, have inventedlcertain new and useful Improvements in Counting Attachments for Printing Presses, of which the following is a specification. My invention relates to improvements in counting attachments for printing presses, and one object of my invention isto provide a counting attachment for that type of printing press which has a horizontally moving bed which carries the type forms and the chase therefor, and which will only count when the machine is actually printing. Another object of my invention is to carry away from the machine the printed matter by means of a conveyor, which conveyor will be prevented fromoperating when the counting mechanism is not in operation, that is to say, when the machine is not printing, and in the following specification I shall show a disclosure within myinvention, and what I claim as new will be set forth in the claims forming part of this specification.

Fig. 1 is a plan view ofthe major portion of a well-known form of horizontal printing press, showing my counting attachment associated therewith. Fig. 2 is a side elevationof the parts shown in Fig. 1. Fig; 2'. is a side elevation of means which controls the operation of the horizontal conveyor. Fig. 3 is a horizontal cross-section on the line 3 8 Fig. 1.. Fig. 3 is a'vertical crosssection on the line 3-3, Fig. 2. Fig. 4 is a vertical longitudinal section on the line 4cl, Fig. 1. Fig. 5 is an elevation of one side of the rear end of the machine showing the operating means for the horizontal conveyor, the action of which is controlled;

by the counting attachment, and Figs. 6, 7 and 8 are vertical sections through the bed showing diagrammatically various relative positions of the operating rod and bail-post roller.

In the drawings, like characters of reference refer to the same parts. i

The type ofmachineI show my counting attachment associated with is wellknown, and is one wherein the printing cyl-' inder A is .journalled in dolly boxes B mounted at each side of the bed C on the frame of the machine, and these dolly boxes pivotally support the paper-feed bail D which is associated with upper and lower J 6 which is provided with a slot 7 whereby this latch is mounted on a pin 8 carried by the bracket 9 which in'turn is suitably supported by the 7 frame of the machine. Mounted to operate longitudinally of the machine is the operating rod 10 which is coupled 'byca spring 11 at one end to the frame of the machine. Pivoted at one end of the machine to the frame is the lock-latch 12'which is provided with a stud 13 which (Jo-acts with the latch 6. 14 is the bumper block carried by the bed of themachine and having the full range of movement of this bed. Coupled to the paper-feed bail D, in the usual way, is the feed-bail post 15, and j'ournalled on a stud carried by the bail post 15 is the bail-post roller 16. The paper-feed bail D is pivoted in the usual way to the dolly boxes B, as shown at 17 and 17 (Figs. 2 and 3),.and the pivoting means 17 extends through the feed-bail post 15 shown in these figures.

The operating rod 10 is provided with a slot 18 into which the bail-post roller 16 must pass before the machine will print. See Figs. 3 and 7.

Suitablv secured to one end of the paper" feed bail D is a post 19, through the $1013 20 of which passes a coupling block 21 flanged atone end asIshown at 22 to hold it in cooperative relationship with the post 19. 23 is a bell-crank lever pivoted at 24 to the post 25 which post is secured to one of the dolly boxe B (see Fig. 3). The post 25 is adapt ed to support the counting device 26, the lever 27 of which is coupled to one end of the bell-orank lever 23 by means of a suitable flexible coupling 28; The upper end of the bell-crank lever 23 is coupled by means of the screw 29 to the coupling block 21, which block of course has movement within the slot 20. Now the bail-post roller 16 is in the slot 18 when the parts are in the position shown in Figs. 2, 3, 4 and 7, and the result is that the tilting of this paper-feed bail has thrown the post 19 to the rights hand, thus through the co-action of the bellcrank lever 23 therewith, depressing lever 27 to actuate the counting device 26. It is wellknown in the art that the paper-feed bail D is under spring control so as to be moved into the position shown in F ig12 when the slot 18 is brought underneath the bail-post roller 16 through the movement of the operating rod 10 when the machinejis printing. After the machine has printed, the operating rod 10 moves the'slot 18 which through the medium of its tapered side a lifts the bail-post roller 16 which eventually rides upon the operating rod 10 as'shown in Fig. 8. As this bail-post roller 161s lifted, the paperfeed bail D is tilted around its pivotal points 17 'andl7, and the result is that the post 19 is moved to the left in Fig. 2 thus moving the bell-crank lever 23 around its pivotal point 24, sothat'when the bail-post roller 16 drops into thei lot lSfthe counting device will be again'actuated. The horizontal conveyor 30 operates around a pair of rollers 31, one only of which is shown, and these rollers are mounted on spindle 32 which are journalledin the side members of aframe 33 supported by, a'pjair of brackets 34 carried by the machine frame. 35 is a ratchet-wheel mounted on and coupled to the spindle 32 shown in Fig, 1, and mounted on thisspindle adj acentsaid ratchet-wheel is a lever 36 to the upper end of which is pivoted a pawl 37 which normally co-acts with the ratchet-wheel 35,. Loosely mountedon the spindle 32 is-a cam I lever 38 which is positioned between the ratchet-wheel 35 and a collar 39 keyed to said spindle 32. The lever 36 is coupled to an arm-40 (keyed to the driven shaft41) by means of the link 42. As the shaft 41 is rotated, the arm 40 operates the link 42, which link in turn rocks the lever 36 on the spine dle 32, and through the co-ac'tion ofthe pawl 37 with the ratchet-wheel 35, operates the conveyor 30.

Now since the post 19 is coupled to the cam lever 38 by a rod 43, and since this cam lever is overhung by the nose of the pawl 37, it will be understood upon referring particularly to Fig; 2 that when the rod 43 is moved in the direction indicated byarrow throughthe movementto the left-hand of the post 19.. that the cam lever 38 will contact with the pawl 37 and move it outof engagement with the ratchetwheel 35., and

. thus, although the lever 36 maycontinue to move, preventthe movement of the horizontal conveyor 30. Whenthe post 19 is moved to actuate the counting device 26, the rod 43 will be moved to move the cam lever 38 out of contact with the pawl 37 and thus permit this pawl to co-act with the ratchetwheel 35 for the purpose before set forth.

There is no necessity of going into the coaction between the lock latch 12 and the operating rodlO, latch 6 and bumper block 14 in preventing the bail post roller 16 from dropping into the slot18 when the machine is not printing because this is wellknown in the art. 7

It is also well-known in the art that some means must be employed to lift the paperfeeler'I out of the path of movement of .the paper as it is fed to the feed rollers E and F Such means is generally indicated in Figs. land 2; and the same comprises a release lever 44 pivoted at '45 to" the block 46, which block is carried by the machine frame. This release lever 44 is controlled in one di' rection of its movement by a spring 47, and in the'other direction by means of a roller 48'pivoted in the upper part thereof and adjacent one side of the block 46. In the position shown of the parts in Fig.2, the

roller 48 has been raised up by the passing thereunder of the bumper block 14. When 'th'eib'ed' moves to the left-hand in Fig. 2,

this bumper'block passes from under the roller 48 thus permitting the spring 47 to move the release lever 44'to the right and bringing it in contact with the arm 4 so as to lift the paper-feeler I.

The conveyor which receives the printed matter as it' issues from the press is wellknown and is generally indicated by the numeral 50. The conveyor of course conveys the printed matter to the horizontal conveyor 30.

What Iclaim is:

l. Ina machine of the class described, the combination with alpaper-feed bail, feeding and printing'inechanism associated therewith; means whereby said paper-feed bail is, pivotally mounted; means co acting with said bail to dominate the movements thereof; afirst conveyor, and a second conveyor embracing a ratchet-wheel provided spindle, of a counting device, means intermediate said counting" device and said paper-feed bail 'whereby'said counting device isactudle'of said second conveyor; a pawl carried thereby to co-act' with said ratchet-wheel; a

cam lever mounted on'said spindle, and a rod connectlng said cam lever with said means intermediate said paper-feed bail and said c ountingdevi'ce, the whole adapted to co-operate; as set forth; I

2. In a machine of the class described, the

combinationwith'a paper-feed bail; feed.-

ing and printing mechanism associated therewith, means whereby said paper-feed bail is pivotally mounted, and means co-acting with said bail to dominate the movements thereof, of a counting device, sup- 5 ported by the frame of said machine; a slotted post carried by said paper-feed bail; a coupling block mounted in the slot of said post; a bell-crank lever pivoted to the supporting means for said counting device, and pivotally coupled at one end to said block, 19 and at the other end flexibly coupled to said counting device.
