2 Claims.

This invention relates to counting mechanisms, and more particularly to improvements in counting mechanisms for coil winding machines.

This application is a division of my copending application Serial No. 19,461, filed March 30, 1925.

- The principal object of the present invention is the provision in high speed winding machines of a simple and efficient counting mechanism which may be conveniently and quickly adjusted or reset preliminary to beginning a winding operation.

Other advantages and" features will become apparent from the following detailed description taken in connection with the accompanying drawings, in which Fig. 1 is a side elevation of a coil winding machine provided with a counting mechanism embodying the features of the invention;

Figs. 2 and 3 are reduced plan and end views, respectively, of the winding machine shown in Fig.' 1;

Fig. 4 is an enlarged plan view, partly in section, of the improved counting mechanism;

Fig. 5 isan enlarged vertical section taken on line 5-5 of Fig. 2;

Figs. 6, '7 and 8 are fragmentary detailed sections taken on lines 66, 7-7 and 88, respectively, of Fig. 5.

Referring now to the drawings in detail, the numeral designates a supporting base plate upon which is suitably mounted a housing 16 and avertical plate 17. A main drive shaft 18 is rotatably journaled in suitable bearings formed in end portions 19 and 20 of the housing 16. Secured to one end of the shaft 18 are a hand wheel 22 and a grooved pulley 23, the other end of the shaft being provided with a chuck 24 which serves to hold a core 25up0n which wire or other strand material is to be wound. The shaft 18 is driven through the pulley 23 and a belt 26 from any suitable source of power (not shown).

The improved counting mechanism is indicate generally in the drawings by the reference numeral 30 and is shown in detail in Figs. 1 and 5. Rotatably mounted in a vertical support 32 formed integral with the base plate 15 is a shaft 31 at one end of which is secured a knob 33. Also secured to the shaft 31 is a sleeve 35 upon which a finger 34 is slidably keyed by means of a pin 36.

so and a slot 37; A sleeve 38 is loosely mounted on the shaft 31 and a number wheel 40, to which a gear 39 is secured by screws 41, is keyed thereto. A sleeve 42 is also loosely mounted on the shaft 31 and has a number wheel 13 keyed thereto. An

annular groove 44 is provided in the wheel 40 (Fig. 6), and a pin 45 is mounted in the groove at a point corresponding to the zero marking on the wheel. A hole 46 is located in the wheel 43 in line with the groove 44 in the wheel 46 and at a point corresponding to the zero marking on 6(1) the wheel 43. A member 47 is keyed to a reduced portionof the shaft 31 and carries a pin 49, one end of which extends through the hole 16 in the wheel 43, and the other end thereof engages one of a plurality of holes 50 in a hubbed disk 51. 5, The number of the holes 50 preferably corre= sponds with the number of markings appearing on the periphery of the wheel 43. The number wheel 43 is held in close proximity with the number wheel 40 by springs 52 which also serve to 74; hold the member 17 in position to retain the pin 19 in one of the holes 50.

A shaft 55, in alignment with the shaft 31, is suitably mounted in the housing 16'and plate 17. Keyed to one end of the shaft 55 and located in ((5 the housing 16 is a worm gear 56 which is driven by a worm 21 formed on the shaft 18. The hubbed. disk 51 is secured to the worm gear 56 by screws 57 Keyed to a reduced portion at the other end of the shaft 55 is a flanged sleeve 58 which carries 86) a pair of pawls 59 adapted to engage a ratchet wheel 60 which is rotatably mounted on the sleeve 58 and keyed to a pinion gear 61 also rotatably mounted on the sleeve. The pinion 61 and ratchet 60 are held in place by nuts 62. When the machine is in operation the worm 21 drives the worm gear 56 which drives the shaft 55 to which the sleeve 58 is keyed and the pawls 59 engage the ratchet 60 and turn the pinion gear 61, thus driving a reversing mechanism which is not further referred to herein as it forms no part of thepresent invention.

Mounted in the support 32 is an apparatus for controlling and driving the number wheel 40 comprising a member 65, one end of which has a flange or disk 66 formed integral therewith and the other end of which has fastened thereto a wheel 6'? having teeth 68 engageable by the finger 34. The inner side of the flanged end 66 has a plurality of depressions 69 any of which may be engaged by a spring pressed plunger '70. A shaft '71 carries a pinion gear '72 which meshes with the gear 39.

As the machine operates the worm 21 through engagement with the worm gear 56 drives the counting mechanism 30. The hubbed disk 51 is driven by the worm gear 56 and the member 4'? is driven by the disk 51 since the attached pin 49 engages one of the holes 50 in the disk. The pin 19 also engages the hole 46 in the number wheel tween the worm 21 and the worm gear 56 is one hundred to one, the number wheel 43 making one complete revolution for each hundred revolutions of the shaft 18. The number wheel 43 is used to indicate the turns in units and tens and has a double column of figures on its periphery arranged consecutively from o to 99. Since each time the shaft 13 completes one revolution, one turn of wire is wound onthe core 25, the number wheel is advanced one one-hundredth a revolution advancing the numbers marked on its periphery one unit.

The finger 34 rotates with the member 47. When one hundred turns of wire have been wound on the core 25 the wheel 43 will have advanced one complete revolution, and the finger engages one or" the teeth 63 and thereby turns the wheel 67 and the member 65 to which the wheel is keyed a sufficient angular distance to cause the spring pressed plunger 70 to engage the next 'depression 69 and for the gear 72 to move the gear 39 and the attached wheel 40 one one-hundredth of a revolution. The periphery of the wheel 40 is marked in the same manner as that of the wheel 43 to indicate the turns in hundreds and thousands. The wheel 40 makesone complete revolution for each one hundred revolutions of the wheel 43 or in other words one hundred turns of wire on the core 25 are required to advance the wheel 40 one unit and ten thousand turns to advance the wheel 40 one complete revolution. The number of turns of wire which have beenwound on the core 25 will be constantly indicated by the numbers on the wheels as just described. It is obvious that the counter mechanism is geared for an extremely high speed winding machine and since only two number wheels are employed as well as due to the simple construction used the parts receive a minimum of wear in proportion to the amount of winding done.

The counting mechanism 30 may readily be changed to a starting position at any time by pulling the knob 33 outwardly. The shaft 31 slides through the sleeves 42 and 38 and draws the member 47 into close proximity with the number wheel 43 thereby compressing the springs 52 as well as disengaging the pin 49 from the hole 50 in the disk 51, and extending the opposite end of the pin through the hole 46 in the wheel 43 into the annular groove 44 in the wheel 40. The sleeve 35 on which the finger 34 isv mounted also slides with the shaft 31 so that the finger 34 cannot engage the teeth 68 of the wheel 67 leaving it free to rotate. The knob 33 may be turned in either essors '43, turning the wheel therewith. -The ratio be direction, rotating the wheel 43 therewith. The pin 49 riding in the annular groove 44 of the wheel to engages the pin 45 mounted in the groove and thereby turns the wheel 40. 1iescribed,-the pin 45 is mounted the groove 44 at a point corresponding to the zero marking on the wheel 49 and the hole 46 in thewheel 43 is located at a point corresponding to the zero marking on its periphery. It is obvious that in the resetting operation the zero figures on both wheels correspond when the pin 49 engages the pin 45.

A pair of levers 121 and 12 secured together and rotatably mounted at to lower ends upon the base 15 are in association with the mechanism just described. A tension spring 123 serves to hold the upper end of the lever 122 in close relation with a member 124 having a slot 125 in its side engaged by the upper end of the lever 122. The member 124 an inwardly projecting end 126 which engages an anular groove 12? in the knob 33. When the knob 33 is pulled outwardly the member H4 is drawn outwardly by the engagement of its end 126 and the groove 12?. The upper end of the lever 122 is forced into the slot 125 through tension induced by the spring 123 which movement causes the lever 121 to fall in the path of a pin 130 mounted on the outer surface'of the gear 39. The top of the lever 121 acts as a stop by engaging the pin 130 when the gear has been turned back far enough for the number wheels to be in position to start anew count.

What isclaimed is:

1. In a counter having a driving element, a shaft driven thereby, and a numeral carrying disc carried by the shaft and rotatable therewith, the combination of a carry-over member mounted on the shaft and rotatable therewith, a. second numeral carrying disc rotatably mounted on the driven shaft between the member and the first disc, and means actuated by the member, for imparting rotary motion to the second disc.

2.- In a counter having a driving element, a shaft driven thereby, and a numeral carrying disc carried by the shaft and operatively connected to the shaft for rotation therewith, the combination of a carry-over member mounted on the shaft in spaced relation to the disc and rotatable with the shaft, a second numeral carrying disc rotatably mounted on the shaft intermediate the member and the first mentioned disc, and in face-toface abutting relationship with the latter, and a train of toothed wheels for transmitting motion from the carry-over member to second-mentioned disc. 4
