COUNTING MECHANISM.

Specification of Letters Eatent.

Patented May 5, 1914.

Application filed February 18, 1913. Serial ITO 749,202.

citizen of the United States, residing at Ardmore, in the county of Montgomery, State of Pennsylvania, have invented certain new and useful Improvements in Counting Mechanism, of which the following is a description; reference being had to the accompanying drawings, forming a part or carrying mechanism,

.in side and vertical mesh with. bevel gear hereof.

My invention relates to registering mechanism particularly adapted for registering the deposition of coins-or like articles and my invention has for its object to provide a device for this purpose which will be inexpensive to construct, efiicient and accurate in operation and may be easily and quickly reset to zero.

With these and other objects hereinafter described in view, my inventionconsists in the construction and combination of elements hereinafter described and particularly pointed out in the claims.

Referring to th drawings: Figure 1 is a longitudinal sectional view of the complete counting mechanism embodying my invention. Fig. 2 is a cross sectional view on line aa of Fig. 1. Fig. 3 is a cross sectional view on line. bb of Fig. 1. Fig. 4 is a cross sectional view on line c0 of Fig. 1. Fig. 5 is a cross sectional view on line (i-d of Fig. 1. Fig. 6 shows in front and side view one of the number carrying rings. Fig. 7 is a longitudinal sectional view of the counting mechanism without the actuating the parts being in position for operation. Fig. 8 is a view similar to Fig. 7 but showing the parts in position for resetting to zero. .Fig. 9 shows section one of the ring gears by which the number carrying rings are operated, Fig. 10 showsin end and side view one of the sleeves; and Fig. 11 is a cross sectional view of shaft 16 on line ss' of Fig. 8.

In the drawings 1 and 2 indicate respectively the front and rear halves of a casing in which the counting mechanism is inclosed, these halves being held together by bolts 22. In the lower part of the casing is journaled a shaft 15 provided with a bevel gear 14 carried by a sleeve 12 which is secured to the shaft by pin 30. The bevel gear 1 1 s in 24 on shaft 25 on which is secured sleeve 26, the outer end of which receives the end of shaft 27 which is the operating shaft and carries the usual star wheel (not shown In order that the shaft 27 may be in proper relative position with reference to the counting mechanism it is flattened on one side as shown in Fig. 5

' and the sleeve is provided with a pin 28. 1 In the upper portion of the casing is journalecl a shaft 16 which is arranged to be capable of a slight longitudinal movement as well as its movement of rotation. Mounted to rotate freely on the shaft 16 are a series of sleeves 8 shown in detail in Fig. 10. having one face fiat as shown at the right in Fig. 10 and hollowed out on the other side so as to form a chamber 8. On its periphery each sleeve is provided with a single tooth 9 extending to the right beyond the flat face of the sleeve and each sleeve is also provided on its flat side with a pin 18 at such distance from the center of the sleeve that when the sleeves are assembled it will extend part way into the chamber 8 of the next adjacent sleeve to the right.

The shaft 16 is provided with a series of pins 17, one for each sleeve 8 adapted when the shaft is moved longitudinally to the left to each engage a pin 18, as shown in Fig. 8. When the shaft is in normal position as shown in Fig. 7 the pins 17 each lie within the chamber 8 of a sleeve 8 out of engagement with the pins 18.,

Each of the sleeves 8 carries a numeral ring 5, shown in detail in Fig. 6, having numerals marked on its periphery and having secured to its left hand face a ring 7 of less diameter than the numeral ring 5. The numeral ring 5 is notched on its inner periphery as shown at 32 to receive the periphery tooth 9 of the sleeve 8 on which it is carried so'that the numeral ring and sleeve will rotate together. The outer periphery of the ring 7 is notched at 7 and into this notch extends a pin 33 carried by the numeral ring 5.

Mounted to rotate on each of the sleeves 5 is a ring gear 6, shown in'detail in Fig. 9 having inner and outer teeth, the inner teeth being so formed as to leave between them spaces 29 adapted to receive the peripheral tooth 9, these spaces being ten in number. There is one of these ring gears 6 for each numeral ring 5 arranged to lie against its right hand face between'it and the ring 7 of the next adjacent numeral ring.

When the parts arein position to be operated asshown in Fig. 7, the tooth 9' of each parts are in posit-ion to permit the numeralrings to be reset to zero the sleeves 8 are pushed to the left a sufiicient distance to withdraw the tooth 9 from the notch 29 of the ring gear 6 so as to permit the numeral rings to be rotated independently of the gears 6. v

To the right hand one of the ring gears 6, as shown in Figs. 1, 7 and 8, which is the ring gear for actuating the units numeral ring, is secured a ratchet wheel 3 having peripheral teeth adapted to be engaged by double spring detent pawl 19 which is mounted on the end of shaft 15. The teeth of this ratchet wheel and the ends of the.

double pawl. are so formed that the ratchet wheel may rotate in either direction. The

detent pawl aids in preventing either overthrowing or underthrowing of the units numeral ring; This ratchet wheel is provided with a hub 3 which is cutaway on the end toward the sleeves 8 so as to permit the tooth 9 of the sleeve 8 which carries the units numeral ring to rotate in it, and is also hollowed out at its center on the end toward the sleeves 8 as shown at .3 to permit a pin 17 to rotate in it. The opposite end of hub 3 bears against the end plate of the casing. In this end of the hub is formed a circular recess 3 in which is located a spring 4: which bears against the shaft 16 to retain it in either of two positions into which it may be shifted. To enable the spring to do this the shaft is provided with an annular groove 35 and with oppositely arranged grooves 36, When the shaft 16 is in the. position in which it is shown in Fig. 7 the spring 4: is in engagement with the annular groove 35 and serves to retain the shaft against accidental shifting in either direction while permitting'it to be rotated. When the shaft is in the position in which it is shown in F ig.

8 the spring is in engagement with the notches 36. These notches are so located that when the'shaft has been rotated asufiicient distance to reset the numeral rings to zero the spring will enter the grooves thus serving to indicate when to stop. the rotation of the shaft in the process of resetting. For

the purpose of easily moving the shaft 16 it is provided on its-outer end with a knob or ring. a

hand hold 21.

Secured to sleeve 13 on the shaft 15 is a gear 10 which meshesfwith the ring gear 6 which is connected with the units numera Mounted on sleeve 12 on shaft 15 are gears 10 and Geneva stop wheels 11, each gear being in mesh with one of the gears 6 on shaft 16 and each Geneva stop wheel being adapted to have the concave faces of its teeth bear against the periphery of ring 7 and to have the notches between its teeth engaged by pin 33.v The Geneva stop wheel 11 which bears against the ring 7 of the units numeral ring is secured to the gear 10 which is in mesh with the ring gear 6 which is connected to the tens numeral ring,-and so on the Geneva stop wheel against which the ring 7 of a numeral ring of lower denomination being secured to the gear 10 which is in mesh with the gear 6 of the numeral ring neXt higher in denomination.

In operation when the shaft 27 is rotated it rotates shaft 525 and through bevel gears 24 and 14: and sleeve 12 rotates shaft 15. This through sleeve 13 and gear 10 rotates the gear 6 of the units numeral ring and as this is locked to the numeral ring by the tooth 9 of the left hand one of the sleeves 8, this will cause the rotation of the units numeral ring. As this completes a rotation its pin 33 engages with a notch 0f the Geneva stop wheel which is at the left of the numeral ring and turns it. This causes the gear 10v which is secured to the Geneva stop wheel to rotate and as this is in mesh with the ring gear 6 of the tens numeral ring the latter will be rotated one space. The rotation of the tens numeral ring through a complete rotation effects the rotation of the hundreds numeral ring, and soon. When it is desired to reset the numeral rings to zero the shaft 16 is pushed inward into the position in which it is shown in Fig. 8. This brings the pins 17 into position to engage the pins 18 and also pushes the sleeves 8 to the. left a sufficient distance to withdraw their teeth 9 from engagement with gears 6. By then rotating the shaft16 the pins 17 will, through their engagement with the pins 18, cause the sleeves 8 to rotate which in turn will cause the numeral rings to ronot desire to be limited to the precise con-' struction and arrangements shown as it is obvious that many changes in details of construction and arrangement may be made without departing from the spirit of my in- 'vention.
