4 Claims.

In the operation of printing presses if it is desired to have the press put out a certain definite number of printed copies, it is customary for a pressman to watch a counter attached to the 5 press and at the correct juncture manually operate a switch to stop the press drive motors. There has been no way of accomplishing this automatically; and in cases where it be desired to include specified numbers of extra'copes for instance, there has been no means for attaining this without trouble and labor out of all proportion to the results. In accordance with the present invention however, it now becomes possible to automatically control the operation of printing presses number. Furthermore, if extra copies should be wanted, Vthese may then be had very easily to the extent of Whatever number of such extra copies as ,may be desired.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which the principle of the invention may be' employed. 1

In said annexed drawings:

Fig. 1 is a semi-schematic showing of the delivery end of a printing press, with control Wiring diagram; and Figs. 2 and 3 are end elevational views, on a.Y large scale, of a portion of the 5 control mechanism, in respectively different position. Fig. 4 is a longitudinal vertical sectional view of the' tallying mechanism T, on enlarged vscale and portions being broken away at the ends and middle; and Fig. 5 is a transverse sec- 0 tional detail thereof, looking toward the left. As indicated in the drawings, the printing press P or the like having paper feed and folding rolls 2, has further 'a cutter cylinder 3 and final fold means 4 feeding to discharge mechanism all 45 of which may be of any usual or desired detail. Arranged to operated by a suitable shaft in such associated mechanism, for example conveniently on the shaft l of the folder linger carrier. means is a'projecting arm 8 which in its revolution about the shaft center actuates the lever I0 of an electric switch Il. Desirably, an antifriction roller 9 is carried en one of the operating elements, for instance, the lever I0. With this then, on each revolution of the shaft 'I, the circuit is made through the switch II and a r and the like, to run out any predetermined set solenoid `I2, thereby actuating the solenoid at each such contact and operating the shaft I3 of tallying mechanism, for instance by a rocker arm Il. A control means is also included in this circuit such that if the paper has broken -or 5 fails, the tallying mechanism will not operate. This may involve a photo-electric cell I5 in the circuit and a source of light I6 opposite, so that normally the paper will shield the photoelectric cell, but on "failure of the paper the light l@ beam will actuate the photo-electric cell and cause the circuit to open. The tallying mechanism T may be of any known or preferred detail construction, different forms being known commercially and further description thereof beu ing unnecessary here, it suiiicing to say that it may involve a series of units, tens, hundreds, etc., step-up gear wheels with visible indicia I8 at the dial and adjacent optionally settable wheels I9 accessible for adjusting to a desired num- 20 ber by opening the housing, and one illustrative construction for example may be on the lines of U. S. Patent No. 2,040,026, and may have the counting wheels I8 and the setting wheels I9 on the shaft 5which is turned up one unit by 25 suitable one-way drive gearing by the r'ockshaft. I3` as it is actuated; it being understood also thatthe wheels I8 for the tens, hundreds, thousands, etc., are loose-mounted to the extent of having appropriate side gearing to ratio, there being ratchet means permitting return movement, and the shaft 5 having a control handle 20 whereby the dial I8 may be returned to zero, and there being also means for setting the predetermining wheels I9 by hand to a desired number which 35 may be run off, whereupon a trip engages and the press drive is automatically taken into control. Such trip operated by the tally wheels may be of a well known form for instance, in which a locking bar'or trip bar t carried by an arm or 40 arms projecting from a rock shaft, is so arranged as to fall into notches on the periphery on the tally wheels I9, as in Fig. 3, when the notches Vin the units and tens and hundreds etc, wheels come to alignment across for the predetermined total number which was set. The detail of this being well known in the art, further description is unnecessary, except to note that such trip rock shaft is shown on the drawings, Figs. 2 and 3, at 22, and at its end outside the series of tally wheels, such rock shaft carries fixedly an arm 23, and with the slight movement permitted the 'rock shaft as the tripper bar aforementioned falls into the nally aligned series of notches when the set number has been run off, the arm 23 has 55 connected at 21 to' another link 28 whose lower endis connected at 29 to an arm 30 of resilient character, fastened to the housing at 3l and carryingfelectri contactor 32 which iscapable of coacting with the contactor 33, and completing the electric circuit 34. The upper end of the link -28 is provided with a hook 36 which, when the link is drawn over to its left hand position, as viewed in Fig. 2, engagesA on ,a ledge 31. thereby holding the contactor arm 36;'up positively against possibility of making circuit through points 32, 33. Only when the rock shaft arm 23 is in its right hand position, as viewed in Fig. 3, will the link 28 permit the contactor arm 38 to drop the contactor 32 against the contact point 33. A spring.38 extending from the end of thevarm 23 to thehousing tends to urge the rock shaft 22 such that the Ilocking bar car-'- ried by it internally will promptly find the notches in the tally wheels when they come into alignment. A spring 39 extending from the housing to the link 28 tends to normally urge it to its left hand position, as shown in Fig. 2. With the structure so far described, it is seen that with each revolution of the shaft 1 in the printing press, as the papers are cut, folded and passed out, the make-arm I0 of the switch Il is actuated, and', if the paper is passing, the circuit is closed through electro-magnet or solenoid i2 thereby pulling the arm I4 of the rock shaft i3 down and ratcheting one on the cumulating gearing. Spring means, Whose detail is immaterial, returns. the-solenoid when the impulse of the current has ceased. When nally the predetermined number which has been set for has been run out, the locking bar afore-mentioned finds the laligned notches inthe tally wheels, the rock shaft 22 correspondingly into the position shown in Fig. 3, andthe contactor 32 drops against the contact point 33 and closes the electric circuit v34. Thereupon, current flows through the electro-magnet or solenoid 40, and circuit 4|, 42, the switches 43 and 44 normally being closed, and the magnet 40 pulls the switchbar 45 carrying, insulatingly, the switcharms 46,I 41, in movement toward the left, as viewed in Fig. l. The arm 46 bridges the contact points 48, 48, establishing a'iiow of line-current through the electro-magnet 58 and its circuit 5|, 52; and the arm 41 makes a continuing circuit through the c'zonta'ctpoints 54, 55 for the magnet 48 through 56, 4I and-'42. The action of the electro-magnet' 58 is to pull the switch-bar 58 to the left, as

vviewed in Fig. 1, and its arm 59 then bridges the contacts 60, 6I, and arm 62 bridges the conu tacts 63,. 64, to complete the circuits from the' line .to the small motor 68 which through gearing 69 s ervesto operate the rheostat R which controls the general motor' press drive through the leads 1021i, 12, the operation now initiated being to move Athe rheostat arm to throw in increasing resistance in the press drive circuit 18,

. 1I, 12 and decrease the drive to nal stoppage.

However, in accordance with the invention, the rock shaft arm 23 of the automatic controlv is provided further with a link 14 extending from pin on the arm 23 to connect at 'I5 to the contactor arm 38. Thereby while the afore-desycribed initiated movement of the arm of the'rheostat R set in motion by the closing of the decrease circuit 15, 16, etc., is under way, the immediately andthe spring 38 pulls the arrnvv 23 ofsucceeding movement of the printing press mechanism shaft 1 operates the switch I l and actuates the electro-magnet I2 and rock shaft I3 once more, which now, with the step-up ofthe first tally wheel' raises the locking bar out of the aligned set of grooves and the rock shaft arm 23 immediately returnsvto the position shown in Fig. 2, with the link 14 pulling the contactor 32 away from the contact point 33 and opening the electric circuit 34.

lf no more papers are desired, the stop switch 44 which is in circuit 4l and arranged such that the arm of the rheostat R will Strike it, is operated as the arm comes to its extreme position. and thiscircuit is opened and the general control is restored ready so that the press can. be

- re-started after being thus stopped.'

But, if before this-occurs the h'and switch 43 is opened the circuit to electro-magnet 48 is broken and the switch bar 45 is thrown by rel turn spring r to a position such that the switch arml 46 is pulled away from the contact points 48, 49, and the currentto the electro-magnet 58 being interrupted, the'switch, bar 58 is retracted by its return spring 'n and the decrease circuit 15, 16, to the rheostat motor 68 is opened. Then however, on hand-closing of a step-up switch 18, an' electro-magnet 19 is energized. This magnet controls the switch bar 80, carrying switch arms 8l, 82, to bridge contactors 83, 84, and 85, 86, thereby allowing flow of current to the rheostat motor 68, and the press motor drive is correspondingly operated to throw out further papers to the 'number as desired, whereupon the switch 18 is opened.

To start the press then for another set of pa- -that where desired, full automatic run for a repeated predetermined number of delivery copies may be had, and if at any time extra copies are wanted, 'a master-control by the'pressman is permitted, whereby he may provide such extra copies as he may desire, and without interfering with the further full automatic control operation. The hand-controlled switch- 98, normally 1 opened, when closed, allows 'hand-control to be interposed for stoppage at any time desired, irrespective oi.' the automatic control.

Othermodes of applying the principle of the invention maybe employed, change being made as regards the details described, provided the features stated in any of thefollowing claims, or the equivalent of such, be employed.

I therefore particularly 'point out and distinctly claim .as my invention: 'g
