290mm. (01. 235-132) a My invention relates to counters.

It has among its objects to provide an improved counter, and more particularly an improved predetermined counter having improved controlling 4 5 mechanism operatively associated therewith. A. further object of my invention is to provide such a counter having improved switch mechanism and controlling mechanism therefor operative automatically upon completion of a-predetermined number of operations and manually cocked in an improved manner as the resetting mechanism of the counter is operated. A further object of my invention is to provide such an improved controlling mechanism operative to maintain the 1:, switch mechanism in its adjusted position after the same has been automatically operated in such manner as to provide a continuing indication, as, for example, by a light or bell tending to call attention to the need for resetting the counter. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

In the accompanying drawing I have shown for purposes of illustration one embodiment which 13 my invention may assume in practice.

In the drawing- Figure 1 is a plan view of a counter equipped with my improvement, its parts being illustrated in starting position, with the cover removed and illustration Fig. 2 is a transverse sectional view on line 2-2 of Figure 1 when the parts are in zero position;

35 Fig. 3 is a sectional view on line 3-3 of Figure 1 showing the parts in zero position and one of the usual driving pawl mechanisms;

Fig. 4 is an end view of the contact mechanism, the wing nut being removed to facilitate illustration, and the parts being shown in starting position; r

Fig. 5 is a similar view showing the parts in full lines in their first operative position during resetting, and in dotted lines in their second operative position during resetting; and

Fig. 6 is a sectional view on line 6-6 of Figure 1 showing one of the reset pawl mechanisms.

In this illustrative construction I have shown a counter of the predetermined type carried in a suitable casing I, and comprising a series of counter units A, B, C and D, each having an adjustable predetermined number wheel 2 and an adjacent counter wheel 3 and adapted to be successively operated by usual mechanism 4, herein of the ratchet, type, and also adapted to be reset the switch casing shown in section to facilitate by a wing nut 5, while-also having improved controlling mechanism hereinafter described and disposed in a supplementary casing 6 carried at one end of the casing I.

'Ihe predetermined counter mechanism, 'including its actuating and resetting mechanism, is

not per se a part of the present invention being the invention of one Harvey L. Spaunburg, which is described and claimed in a co-pending application, Serial No. 528,819, filed April 9, 1931 and assigned to the assignee of this application, so that a detailed description of the same seems unnecessary. It will, however, be understood that the first unit A is operated in any suitable manner, as, for example, herein, by the lever of the ratchet mechanism 4, and that it is connected through usual transfer mechanism including a mutilated transfer pinion 'l rotatably mounted on shaft 1a to the unit B, while the units B, C and D are similarly connected to one another in a well known manner. It will be evident that the teeth on the mutilated portion of transfer pinions i cooperate with the two-toothed carrying gear 'lb (Figures 1 and 6) of the lower order wheel while adjacent teeth of this mutilated portion of the pinion engage the periphery of the locking disc 10, and that the unmutilated portion of pinions 1 are constantly in mesh with the gear id of the counter unit of the next higher order, all in a well known manner in the art. It will also be evident from Figure 1 that since the teeth on the unmutilated portion of each pinion 1 project inwardly beyond the periphery of the locking disc lc on one side and relatively axially fixed counter wheel 3 on the other side, the transfer pinions I cannot be axially displaced on shaft la. It will also be understood that the members 2 are adjustable about their axis relative to the members 3. into any desired position to set the mechanism for any predetermined number of operations and that the several members 2 and 3 also have operative connections (not shown), whereby, after each adjustment, the members 2 and 3 may move together during counting. As shown, the members 2 are also, as usual, provided with suitable notches 8 adapted to come into alignment in the zero position of the members 2 and be engaged by rollers 9 on a swinging frame NJ. The latter in turn is connected through usual gearing II and I2 with a controlling shaft 13 in such manner that, when the members 2 are at zero and the members 3 indicate the predetermined number desired, the latter shaftis moved about its axis. It will also be understood that after-the predetermined number of counting op erations has occurred and the shaft 3 has thus operated, the mechanism may be reset 'by the wing nut 5 which in turn rotates the counter carrying shaft it, provided with the usual keyway l5 and adapted to co-operate with the usual pawls l6 (Fig. 6) in such manner as successively to pick up the counter units and as usual return the same to their initial position illustrated in Figure 1, wherein the predetermined number will appear upon the number wheels 2 and the number wheels 3 will be at zero. It will be understood that with the well known counter units and transfer mechanism herein shown, the independent rotation of the several counter units during resetting is permitted by reason of the customary pawl and ratchet mechanism (Figure 3) including a pair of spring pressed pawls |5a carried by the gears ld which cooperate with the internal ratchets |5b carried by counter wheels 3, permitting free rotation of each counter wheel 3 in a resetting direction, irrespective of the interconnecting transfer pinions.

'In my improved construction I have provided improved controlling mechanism adapted to cooperate with such a counter in order to enable improved results to be obtained. More particularly, it will be noted that, as shown in Figure 4, I provide the shaft I3 with an operating lever |1 projecting into the switch casing 6, while I also provide acam |8 on the end of the shaft H projecting into that casing, the wing nut 5, as shown in Figure 1, being spaced from this cam and carried on the extreme end of the shaft ll. Herein also it will be noted that the operating member I1, which is connectible by any suitable adjusting means, as a set screw I9, to the shaft I3, is also provided with two pins 20 between its ends and also connected at its outer endby a coiled spring 2| to a suitable connection 22 inthe top of the casing 6. Moreover, it willbe noted that a pivotal member 23 extends between the pins 20 and upward to the top of the casing adjacent the connection 22, where it is pivotally connected at 24 to a transversely disposed latching member 25. upper endof a spring member 2'|,'the lower end of which is attached as by a screw 28 at the bottom of the casing. Moreover, it will be noted that the member 21 carries a laterally projecting pin or operating member 29 which operates any suitable type of switch mechanism S, herein of the normally open type and operable by the pin 29 through an intermediate pin 29 reciprocably mounted in the switch casing. As shown, the

free end of the member. 25 also has a hook or latch 30 formed thereon adapted to hook over acorresponding upstanding projection 3| carried near the top of the opposite wall of the casing 6. Herein, it will also be noted that a coiled spring 32 is connected to the-member 25 substantially midway between its pivots 24 and 26, and also has its opposite end attached to the bottom of the casing 6 as at 33.

In the operation of the construction, it will be understood that the parts will assume the posi- 'tions shown in Figures 1 and 4 when in starting position, i. e. when the predetermined number of counter mechanism has performed the desirednumber of operations, it will be evident that as the rollers 9 drop into the notches I, the shaft II will The latter in turnispivoted at 26 on the be operated through its connections including the spring 2| and gearing l2, which are constantly tending to operate the same but are prevented by the members 2 until the notches 8 come into alignment. More particularly, the spring 2| pulls up the free end of the operating member l1 and thereby causes the pins 2|] to clutch the member 23 and moves the latter upwardly and, through the member 23 pivoted at 24 on the member 25, raises the latch 30 on the latter and disengages it from the member 3| in such manner as to release the spring 21 and accordingly enable the same to push in the contact actuating member 29 and thereby close the circuit, as necessary, as, for example, to light a light, ring a hell, or shut down the machine, as may be desired. Here, it will also be noted that the parts will remain in this position until the mechanism is reset, irrespective of whether the rollers 9 remain in the notches 8. Thus there is given a continuing indication that the predetermined count has out of notches 8. When, however, the operator operates the wing nut 5 to reset the mechanism, this will bring the actuating portion on the cam l8 into engagement with the under side of the member in such manner as to raise the same and cause its latch to clear the projection 3|, while further rotation of the cam |8 will force the member 23 to the left and swing the latch 30 down over the projection 3| while tensioning the spring 21. Thus, the switch mechanism will be cocked by the resetting operation of the shaft M in such manner thatthe circuit connections for the light or signal will be automatically made ready for automatic closing as soon as the desired predetermined number of operations has again been performed.

Attention is also directed to the limited range of movement of the reset member permitted without operation of the contact mechanism by the engagement of the actuating portion of cm l8 with its associated mechanism. Thus, it will be noted, that if the reset .member is moved through more than this limited range of movement, the contacts are closed in such manner as to cause the illumination of the light, the ringing of the bell, or the shutting down of the machine, depending upon the particular means in circuit with the contacts. This provides marked further complications for an operator seeking to advance the count of the counter fradulently by manipulation of the resetting mechanism, and thus materially restricts his freedom of manipulation of the latter. More particularly these restrictions arise not only from his fear of inadvertently closing the contact and thus attracting the attention of a supervisor to him, but also from the limitation on his freedom to move the reset shaft, which tends to make him fear that he will oversteal. As a result, he will be able to steal only small amounts in certain limited ranges, something which many operators will either not discover, or be afraid to use for fear of operating the light or other signal.

As a result .of my improved construction, it will be noted that it is also made possible to apply my improved control mechanism to a counter of the type illustrated with a minimum of change in the latter. More particularly, it will be noted that the whole casing 6 is connectible as a unit to one end of the casing by suitable corner screws, suitable apertures for which are shown as at in Figures 4 and 5 while the cam l3 and operating member I! are readily connectible to the ends of the shafts I4 and I3 protruding through the adjacent end of the casing I. All the rest of the mechanism, it will be noted, is carried by the casing 6, including a switch casing 36 housing the switch mechanism S. Thus, where it is desired to apply my improvement to an existing counter, this may be very readily done with a minimum of expense.

While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that the same is shown for purposes of illustration, and that the invention may be modifiedand embodied in various other forms and adapted-to other forms of counters without departing from its spirit or the scope of the appended claims.
