REPEATING-COUNTER- To. all 'whom 'it may concern Be it .known that I, VViLLIAM GRUNOW,

I Jr., a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Repeating- Counters; and I do hereby declare the following, when taken in connection with the accompanying drawings and the .characters of reference marked thereon, to be a full,

. clear, and exact description of the same, and

' my invention.

which said drawings constitute part of this application, `andl represent, in-

Figure 1 a top or plan view of a repeating counter constructed in accordance with Fig. 2 aside view of the same,` showing the mechanism adapted to movefin one direction. Fig. 3 a similar view showing the mechanism adapted to move in the opposite direction. Fig. 4 a side view the reverse of Figa- 2 and 3. v Fig. 5 a broken sectional view showing means for fixing the c position of the index.

This invention relates to an improvement in repeating counters, the object being to provide a counter which will operate a predetermined number of times' in one direction, then reverse and operate an equal number of times; for instance, where three op erations are performed the Idevice will opcrate in one direction three t-im'es, then reverseand operate three timer, and repeat this counting by .three as lo gas required, and at thesame time register the number of serieso'f three or any other predetermined- As another instancev of 'use 1n number. measuring thread, the. device can be adjusted to operateat the end'of each hundred yards and register the number of hundred yards passing; and the invention 'con.

of the screw shaftv with respect to its threads,

a pin 9 may be passed through the end of thepost 8 and into the threaded shaft 7. On thisscrew sh'aft'are mounted a stopwheel10 and an index-wheel 11 provided respectively with threaded hubs 13 and 12 which free'lyJit they screw shaft 7 to permit of being rotated about thesame. The stopwheel 10 is toothed'and meshes with the. A

`pinion 3 by which it is driven andcaused to rotate about the screw shaft 7,' and to travel lengthwise with its axis, whereby the wheel 10 is caused to travel spirallyx Theindexwheel 11 preferably has itsrim graduated into divisions corresponding with the number of teeth in the stop-wheel V10. Around` the hub 12 is a split collar 52 the ends of which are.. connected by a screw 14 by which theihub may befconnected with the screw shaft 7. The collar 52 is also provided with an outwardly projecting index-arm 15 which is perforated at its outer end for the passage through `it of a graduated rod 16 'hereinafter referred to. IPassing.through `the screw shaft'7 is a freely fitting shaft 17 which is firmly secured at one end`to an `arm 187Which supports one end of the graduated rod `16, the divisions of which correspond with the pitch ofthe screw shaft 7. The other end of the graduated rod is mounted in an arm 19 fixed to the' shaft 17. A double pawl 20 is mqunted on a stud 21 mounted in the outer end of a crank arm of alever. 23 which is pivotally mounted on the base which base is providedwith stop-lugs`24'and 25 to limit the movement of the lever. The double paWl 20 comprises an upper pawl' 26 and a lower 'pawl 27 adapted to engage with the teethof nthe sprocket wheel v2, one pawl causing the sprocket to' turn in one direction and the other in the opposite direction, the lengt-h of the stroke bein fixed by the said stop-lugs 24l and 25. To t(Iiold the sprocket wheel during the return stroke of either of the pawls, i I employ a detent 28, and to causel the return movement of the pawls Iemploy a spiral spring 29. slde of the double pawl 20 are two plus 30, 3l, between which al flexible strip 32 extends, thisstrip being fixed to the arm 18, and at theother end extending over the stud 21 von which the double pawl is mounted, the outer end of this stud being flattened, and so that the strip 32 may have a bearing upon 'IUv Projecting outward from one continued operation of the lever 23 then re-` either the upper or lower side of the fiattened portion. To provide a lock for the armslS vand 19 in the two positions, I mount` a locking-lever in a bracket 34 secured to the base 6, and form this locking-lever with two notches 35, 36, either of which may be engaged by the graduated rod 16, thelcver being forced against the rod by a spring 3T.' The lever is also provided at its upper end with a hammer-arm v38 which will engage with a bell 39 when the graduated rod is shifted. The stop-wheel 10 is provided with an actuating pin 40 projecting from opposite sides, and the index-wheel 11 is provided with a count pin 41 adapted`- to be engaged by one end of the actuating pin 40, the other end of which pin 40 is adapted to engage with the arm 18. The indexwheel 11 being set at the desired point and the lever 23 operated, will cause one or the other' of the pawls 26 or 27 to engage with the sprocket 2.

As shown in Fig. 2 of the drawings, the pawl 26 will/engage with t-he sprocket wheel 2 and each downward movement of the lover 23 will turn the sprocket one tooth and move the wheel 10 a corresponding degree. At this time the strip 32 bears against the lowerpin 31 carried by the double pawl, and the graduated rod 16 is held by the upper notch 36 in the lever 33. A continued operation of the vlever 23 will move the stopwheel 10 a predetermined number of times and until the actuating-pin40 carried .by the wheel 10 engages with the count-pin 41 carried by the index wheel 11, and these pins are so arranged that the stop-pin 40 will en'- gage with the top of the count-pin 41 so as to depress the graduated rod 16, and hence depress the arms'18 and 19, and this depression of the arm 18 shifts the double pawl 20 so that the lower pawl 27 is in position" to engage the teeth of the sprocket 2. 'The verses the movement of the pinion 3 and hence reverses the movement of lthe stopwheel 10 which will turn upon the screw shaft 7 until the opposite end of the stoppin 40 engages with the underside of the arm 18. The number of movements necessary to cause this engagement, being the same as was required in the opposite irection, so that b adjusting'the index-wheel 11 on the screw s yaft 7, the sprocket wheel may be moved one tooth in one direction, then reverse and move one tooth in the opposite direct-ion, or it may be adjusted so that one thousandor more movements in one direction are necessary to bring the stop-pin into engagement with the index-wheel, and the vsame number of operationsy in the return direction; and at each shift .the bell will be sounded. Fixed to the end \of the shaft 17 is a lever' 42 which operates a'series of conntilngwheelsl43, 44 Vvand 45 usual ccnstruction by which each shift of the graduated rod is registered, thus indicating at once the number of series of any predev termined number.

Instead of operating the pawls b the lever 23, the pawls may be operated y an eccentric 46 mounted on a shaft 47 andadapted to engage with the stud 21on which the double pawll is mounted. This shaft may be turned by mounting a worm wheel 48 upon it and providing a worm 49 on a shaft 50 operated by a grooved o'r other wheel 51 by which the worm maybe turned. This wheel would be of such size that a predetermined number of revolutions would operate the cam at the desired time to move the pawls; for instance, in measuring thread, the wheel could be of suchl size that each one, or two, or three, or any other number of hundred yards if passed over it would shift the pawls.
