This invention relates to counting mechanism for counting the products of a machine and to the control by the production to stop the machine drawings in which Fig. 1 is a side view, largely diagrammatic in form, showing one form of this invention as applied to a dispatch conveyor for delivering the products of a newspaper printing machine;

Fig. 2 is an enlarged view of the subtraction counter;

Fig. 3 is a view similar to a part of Fig. 1 showing the counter control device in a different position;

counting wheel in the position it assumes when there are no further papers to be run through it, and

Fig. 5 'is a side view of the same in that position.

In a previous patent application, Serial No. 224,567, filed Oct. 7, 1927, I have illustrated and described a production controller which controls the combined production of several printing presses or other machines. In that application no provision was made for deducting automatically from the recorded quantity the number of papers which, although delivered in the delivery room, are found to be unfit for use and can properly be 40'-deducted from the record. Another correction has to be made for papers which are delivered on the delivery at the folder, but are removed therefrom by the pressman for inspection or elimina tionbecause of defects which he may find as a result of his inspection. A This invention is designed for making up the deficiency caused by removal of papers for defectiveness or for inspection. It is shown in the first five figures as connected with the folding machine 10 which, through its delivery fan 11, delivers papers to a series of parallel spaced delivery belts 12 which conduct them through a dispatch conveyor, as indicated, to a series-of belts 13 in the delivery room. These papers pass a 55 counting wheel 14 having teeth or corrugations in Fig. 4 is a view similar to Fig. 1 showing the its circumference which is located between two of the belts and therefore is rotated by the papers and when connected by a magnetic clutch 15 gives impulses through a line 46 to a production controller which is connected in said line and Q30 which may be of any desired kind, including the kind shown in my above identified application and is illustrated herein diagrammatically at 6. This connection is made through a commutator 17 of ordinary construction and, as shown, oper- 5 ates the counter once for every-ten: papers deliveredf 1 1 The shaft 18 on which'the magnetic clutch and counting wheel are mounted is pivotally mounted by means of arms 19 and provided with a spring 20 for holding it towards the papers. When the papers have passed beyond it as shown in Figs. 4 and 5 the wheel 14 will engage a brake pad 21 which is'corrugated on its face to stop the counting wheel and hold it in fixed position.

The line 16 is connected through a suitable source of power as 22 with a contact 23 adapted to be completed by a contact 24 on a lever 25. This lever can be set in two positions as indicated in. Figs. 1 and 3. In the position shown in Fig. 1 it completes a circuit through the battery 22 and the contact 24 with acontact 26. This operates a magnetic clutch 27 on a shaft 28 connected by gearing 29 with a shaft 30 carrying the pulleys for supporting the belts 13. The energizing of this v clutch 27 causes a crank 31 to rotate and operate a subtracting counter 32. This subtracting counter may be of the type set forth in my above mentioned application or an ordinary counter may be used which is set back from zero to operate in the ordinary way, as will be explained.

When this counter 32 comes to zero it establishes a circuit 33 through a solenoid 34 and attracts the end of a lever 35 on the other end of which is a latch 36 which normally holds the lever 25 in the position shown in Fig. 1. When this solenoid is operated, therefore, the lever 35 will release the lever 25 as shown in Fig. 3 and a spring 37 will draw it back so as to bring the contacts 23 and 24 into contact and break the contact at 26.

The operation of the device is as follows: When the machine is operated normally the lever 25 is in the position shown. in Fig. 3 and the magnetic clutch 27 is open. Also the counter 32 is not in action but the ordinary counter 47 connected with the line 46 is operating in the usual way, the clutch 15 being energized. Now when a number of papers are taken out, the counter 32 is set by hand so that when it operates a number of times equal to the number of papers removed it will come 110 back to zero. In the case of a subtracting counter such as used in my abovementioned application it is set by hand to indicate the number of products which have been removed and then its subsequent operation to record that number of papers or other articles will bring it to zero. If an ordinary counter is used it could be set back to a position enough under the zero position to cause the number of papers to bring it back to zero. For example, it could be set to 99983 if seventeen papers were removed. Then it would indicate zero. when seventeen more has been delivered with the clutch 27 energized. At any rate having set the counter the operator then moves the lever 25 from the position shown in Fig. 3 to that shown in Fig. 1 and the magnetic clutch 27 is connected so that the counter 32 will operate and the clutch 15 is deenergized. When it comes to zero the solenoid 34 is energized and the lever 25 restored to normal position as shown in Fig. 3 and the machine is ready for operation again. This release of the handle 25 also breaks the circuit to the solenoid andto the magnetic clutch 27 as will be understood readily.

It will be seen that in the normal delivery of papers to the delivery room the wheel will cause impulses to be sent to the production controller as long as papers are being delivered to the mailing room. 'When the flow of papers is interrupted by the total number desired being delivered, a signal is given by the production controller which is not shown herein. Then the operator moves the handle 25 which prevents further impulses being sent to the production controller and the subtracting counter 32 is set-by hand as stated. Then this automatically stops the machine or' machines after that number of papers has been made upor gives a signal as desired.

It will be seen thatthe production controller can be connected up to operate as set forth in' the above identified application, or in any other desired way, to record the combined production of several printing presses or other machines and that when papers are abstracted from those recorded, when they get to the delivery room on account of being unfit for use, and other papers are removed by the pressman for inspection or because of defects, they are deducted from the count. In other words other papers are supplied in the usual way and the machine or machines are stopped automatically or a signal given when the total number of papers actually delivered in good condition is equal to the number recorded in the production controller.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed inthe claims. Therefore, I do not wish to be limited in this respect but what I do claim is:-

1. In a counting device for the purpose described, the combination with a conveyor for transferring articles, of a counting wheel movably mounted, means for normally forcing the counting wheel against said articles, a brake in position to be engaged by the counting wheel and stopping it when the articles have passed it, a shaft on which said wheel is located, a commutator and magnetic clutch on said shaft, and a counter connected with and controlled by said commutator for counting the articles delivered in accordance with the rotation of said shaft.
