The following specification relates to my invention in an interruptible revolution counter and numbering head for press cylinders. More specificall itfiS for giving consecutive number- .ing to the revolutions of press cylinders capable used; and

of being rendered inoperative by a momentary intenuption n the vent of the production; of printing rendered defective by splicing of the paper webs:

mechanism for interrupting the numbering de- Fig. 5 is a plan view of the same; Fig, 6 is a diagram of the electrical .Fig. 7 isa view of one former 81311061 My invention is used in conjunction with'a ro- .tary: printing press having a splicing means and a paper throw-out device such as is disclosed in It is usual practice to splice successive. webs, of the Wood Patent 2,048,765. The splicing me hapaper as theyare fed to a rotary press. -The" splicing operation may be by hand or automatic. It results in the production of a defective printed *unit which must be discarded. The discarding of such a printed unit results in an error of the num-, bering machine by which the successive impressions of the rotary press are counted and marked. In the patent 'of H. A. W. Wood granted July 28,

,1936, No. 2,048,765 a throw-out-device has been disclosed in which the automatic pasting mechanism sets into motion mechanism which results in displacing askew the printed and folded unit 4 containing the section of spliced paper;-

. One of the objects of my invention is topro vide a numbering mechanism for use in conjuncvtion with a throw-out device operating accurately to correct for the individual printed units discarded by reason of splicing detects. A further object of my invention is to interrupt" the normal operation of such a numbering device in response to abnormal conditions or events.

One of the objects of my invention is to safeguard the numbering machine from inadvertent and accidental interruption not connected with the occurrence of an event which i 'is esired to therewith appropriate means 'for interruptingdisregard in numbering. A, still further object of my invention is to provide equipment for the above purposes which will be adaptable to existingprinting presses and which will be actuated by the ,operationot splic- 40 ing webs in the normal operation of existing Fig. 2 is an end view of the same terse-ii. veris a vertical cross-section on the line nism shown in this Patent 2,048,765. is shown in 1 w the present caseat Fig. 7,'where in the running web W and the web roll I00 are associated with I50 rotating with the web roll. The roll I00 after it gets into the prone! position is started into roeach rotation the cam I50 closes the contacts I30 and I40; Thisoccurs whenthe pasted spot on the roll I 00 reaches the proper position for attachment to the web W. I have shown the pasting device in' a form involving a bri'ishplfllior' finally bringing the parts together. Such a press includes the pasting or splicing mechanism dia-.

tions, Figs.'2- and 3, as more clearly apparent from Fig. .4. 'To this mechanism} I have added a num bering mechanism by which theprinted imprea' sions are successively numbered andfcombined the numberingdevice or'rendering it inoperative so that the defective copies will be disregarded.

In drawings I have shown a cylinder or ro- 4 plate cylinder 8. The web 9 travels vertically between the cylinders I and 8, each rotation of the;

latter representing a printed impression which it ing made-to disregard from the num eri any 4 impression on a spliced section oi. the web-il.

' The cylinder a has a reduceden'd III as shown in. Fig. 2. Inwardly or the reduced endthe cylnumbering machine is actuated by a shaft II rotatablyjournalle'd in there duced end I0 oi the. I

cylinder 8 as shown in Fig. 2 and carrying star wheel I3.

' is desired to number, suitable provision also beinder shes a recess II in which a numbering 1 machine I2 is appropriatelyjom'nalled. This the delivery.

The frame 6 has a bracket l6 which supports an electromagnet IT. The solenoid or plunger 18 of the electromagnet is held down by gravity and carries a pivoted link I!) from which is suspended a pawl 20. The pawl 20 is in the form of a lever which is pivoted as at 2! to the frame. A spiral spring 22 serves to hold the pawl in its lower position in thepath of the star Wheel [3. In this way the pawl actuates the star wheel once in.

, journal 24 in which rotates a shaft 25. The rate of rotation is controlled by the operation of the printing press. The end of the shaft 25 is in the form of a spiral worm gear 26. A lower bracket 21 extends laterally from the standard 23 below the shaft 25. A companion bracket 28 -extends laterally from the standard 23 above the cam "determines how long solenoid II will remain energized.

Current is supplied through circuit 49 simultaneously with the formation of 9. splice by the usual pasting mechanism. This current flows through electromagnet 31 retracting the latch 39 and permitting the drum 32 to rotate by frictional engagement with the friction disk 3 I. This brings cam 40 past the switch 4| closing the circuit 50 to the signal 5| and magnet 52. The latter operates the kicker 53 to oflset the defective printed copy which has by this time reached the delivery mechanism.

shaft 25. Brackets 21 and 28 form journals for a shaft 29. Above the lower bracket 21 shaft 29 carries, keyed or otherwise attached, a worm wheel 38 in engagement with the worm gear 25.

Above the bracket 28 shaft 29 carries a friction disk 3 I. The upper end of the shaft 29 has a loose I clutch or drum 32. This drum 32 is held down against the friction disk 3| by a spring 33, washer electromagnet 31 mounted on the upper bracket 28. The solenoid or plunger 38 of the magnet is provided with a latch 39 which may be urged outwardly into' the path of the detent 3G. The plunger 38 is biased for normal position to be positioned in the path of the detent 35.

' The drum 32 carries a peripheral cam'40 suitably spaced with' respect to the detent 3B. Normally in the path of the rotation of the'cam 40 there is a switch 4|. This switch" is open except when it is moved back by contact with the cam 40. r A secondcam 42 is formed on the peripheral of the drum 32 and suitably spaced from the detent 36 and the first cam 40. Bracket 28 is extended to form a column 43 on which is mounted a normally open switch 44. This switch has a plunger .45 normally extending outwardly into the path oftravel of the cam 42. As the cam 42 passes plunger 45 it closesswitchl l.

In the order of their sequence. the latch 35 is withdrawn from detent 35 the moment the splice is made and drum 3.2 begins to turn, then cam 42 closes switch 44, energizing solenoid II which makes the numbering head inoperative. Thenwhen the unnumbered conies arrive at the delivery, cam 45 closes switch 4] to make kicker 53 operative for setting the. defective copies askew on Electromagnet I I is provided with a holding Y orbridging switch 46 so that the circuit once closed through magnet l1 remain closed until Q interrupted. In order to'interrupt this circuit I have provided a cam 41 on the shaft of cylinder 8. This cam 41 operates a circuit breaker 48 .once every revolution. The switch breaker 48 and cam 41 are used to insure. that the solenoid l1- can,be energized only when the numbering device is not in actual operation. The length of In appropriate time sequence thev cam 42 closes the normally open switch 44. This energizes the electromagnet H which lifts its plunger l8 thus taking the latter out of the path of the star wheel l3. As the circuit breaker 48 is closed the current continues to flow through the solenoid 11 holding the latch 20 out of the path of the star wheel 13. However, the cam 41 operates to open the circuit breaker 48 once in every revolution.

Cam 4! opens the circuit breaker 48 for a brief interval, each revolution of cylinder 8 to prevent lifting of pawl 20 during the brief interval during which changing of the numbering mechanism takes place to prevent incomplete or partial operation of the numbering head.

Operation of the several details of this assembly has been indicated above. At the time when 2. splice is made solenoid 3'! retracts the latch 39 permitting the cam drum to revolve with the friction disk 3| of shaft 29. The worm gearing is such as to bring cam 40 opposite switch 41 when the defective printed copy reaches the delivery machine. Thus the kick-out device 53 displaces the defective copy and the signal 5| is energized. Further rotation of the cam drum 32 brings cam 62 in contact with switch 44. The circuit is then closed from line '58 through the magnet I1 and the latch on the pawl 20 retracted out of the path of the ratchet wheel I5. Since circuit breaker 48 is closed the latch remains retracted until cam 42 permits switch 44 to open and deenergize magnet H. The length of cam 42 can be made to suit the length of web desired to pass through th press without being numbered. The

pawl 20 then falls back into the path of the star wheel l3 and the numbering continues.

This arrangement provides for the normal operation of a numbering head without interruption until a splicing operation is performed. On the occurrence of splicing a web, the numbering head is rendered inoperative, and the defective copie are ofiset from their ultimate normal delivery. The interruption of th num b'il'illg sequence may precede the ofisetting delivery operation. Thus the cams on drum 32 may be arranged in such an-order'that the interruntion of the numbering will occur as the spliced portion of the web passes the numbering head and prior to the operation of the kicker when the spliced portion" finally reaches the point of delivery. 1
