' ',ELEc'rmc COUNTER Fon Box-MAKING MACHINES.

vTo all whom t may concern.'

Be it known that I, HAROLD S. LABOM- BARDE, a citizenof the in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Electric Counters for Box-Making Machines, of which the following is a speciication. l

This invention relates to means for counting the product of a box-making machine, and refers particularly to devices adapted to be attached to machines of present make, so as to count the bofXes as they issue from the machine in at folded condition.

One of the objects of my invention is to provide an improved device of the character stated which will perform itsV work accurately regardless' of the size of the blanks e or boxes or the speedwith which they pass.

Another object is to provide an improved enables an attendant lots'of the articles in to pick up assembled for packing, but

predetermined quantities,

also'exhibits the total number of such lots.

With these and other objects in view, my .invention consists in the construction and combination of parts substantially as hereinafter described 'and claimed.

Of the accompanying drawings- Figu res 1 and 2 are opposite side elevations ofthe machine, someunnecessaryparts being omitted from Fig. 2.

Fig. 3 represents a sectional plan on line 3v-3-of"Fig. 1; f'

Fig. 4 represents Figs. 5 and 6 are, respectively, side and edge views of the insulating disk which controls the circuit breaker. Fig. 7 is a detail plan to illustrate the means for operatinga mechanical counter; Fig. 8 is a diagram to illustrate the elec-l tric circuit; j Fig. 9 is a view illustrating a modification. 1 The frame 20 of the mechanism is provided with lugs 21 forming sockets by means of which the frame-can be hung on suitable rods or parts of the box-making machine to' bring the throat hereinafter described t6 proper position;

The frame is adapted to be clamped in position by screws 22.

Vertigally mounted in the frameis-a shaft k23 having a ratchet 24, said ratchet omitting a few teeth to form a blank space 25 (Fi Secured to the upper end of the sha is an arm 26, and secured to the lower end' of the shaft is another arm 27 having a pin'28.

Mounted to slide vertically in the lower a stop pin 46 operated as hereinafter described and adapted to intermittently release and stop rotation of the kicker arm 39.,

The operation of the mechanism as so far described is as follows -The constant rotation of the pulley l34'causes the pawl29, to rotate the -shaft 23 step by step until the space 25 of the ratchet arrives under said' first portion of the rotapawl. During the tion of 'the shaft, the kicker arm is carried two oppositely ded Q v v 1,298,518

same completion of a circuit as already described, causes the pad 131 to momentarily pinch the edge of a passing box a' between it and pad .130 and then release it. The. ads

are preferably of friction material suc as rubber.v As the" carrier Abelts 69 travel con- A tinuously, the momentary arresting .of a side or edge portion of a folded box by the pinch- N o clrcuit-complet- 131 is adapted to cooperate, said release pre-determ1ned number of. boxes.

In acounter of the character described, a shaft having a disk provided spiral groove in its perlphery, means for rotating'the shaft stepby-step by thepassage of boxes, normally ineiective means controlled mechanism for ei'ecting `ther operation of said displacing means, 'a universallymounted lever having'a projection bearfor displacing boxes outA of their normal path oftravel, electrically l l l Legame ing on the periphery of said disk, means for closing the electric circuit when said projection is in the recess of the disk, means whereby said circuit is interrupted while said projection is in the groove of the disk, and means controlled by the box displacing means,v for actuating said lever to shift its projection from the recess of the disk to the peripheral groove thereof.

28. A counting attachment for box-making machines, comprising a guide for the successive passage of boxes, a ratchet, means controlled by the passage of each box for actuating the ratchet, an electric circuit, means operated b said ratchet for controlling said circuit, a magnet in said circuit, a lever having an armature at one end and a pad at the other end, and a xed pad, the two pads being in position to grasp a portion of a passing boX When the circuit 20 of the magnet is closed.

In testimony whereof I have affixed my signature.
