London, England Application August 29, 1936, Serial No. 98,520 In Great Britain January 3, 1935 2 Claims.

This invention relates to improvements in registering apparatus for incorporation in totalizator and like equipment, of the type adapted to receive bet signal impulses directly or indirectly from ticket-issuing and like machines and including stepwise-operated primary mechanism.

The present invention provides improved apparatus of the type referred to including a series of register discs each of which, after the first or units register disc, is driven from the preceding register disc by means including a cam driven step wise by the preceding register disc operating mechanism and operatively connected to a toothed Wheel of the succeeding register disc operating mechanism whereby to impart a step of rotation to said toothed wheel in the final step of rotation of said cam.

Registering apparatus constructed in accordance with the present invention is illustrated in the accompanying drawings in which Fig. l is a rear elevation, Fig. 2 a part plan part horizontal section and Fig. 3 a fragmentary elevation drawn to a larger scale of the transfer mechanism which interconnects one register disc with a succeeding s- -register disc.

The registering apparatus shown includes an electro-magnet I (Fig. 1) which receives electrical bet-representing impulses to be counted and which imparts oscillatory movements to an armature lever 2 attraction of which to the electro-magnet I is opposed by a pair of springs such as indicated at 6. The armature lever 2 carries a pawl 4 adapted, in the return vibrations of the armature lever Zunder the action of the springs 6, to impart stepwise uni-directional rotation to a ratchet wheel 5, reverse rotation of which is prevented by a detent 5'. The ratchet wheel 5 transmits rotation to a spur wheel 9 through accumulator mechanism forming the subject of my co-pending application Serial Number 98,519, filed August 29, 1936.

Each impulse transmitted by the spur wheel 9 to a rotary digit-displaying disc I! geared thereto counts unity, digits 1-9 and 0 beingequispaced circularly on the front face of the disc I! which is rotated through one-tenth of a revolution for each transmitted impulse, so as to exhibit a digit. The digit disc [1 and its associated driving mechanism constitutes a first or single units indicating apparatus.

A digit is exhibited by the disc ll when said digit registers with a window in a front panel (not shown) of the apparatus.

The first or single units register disc may be actuated by two such driving mechanisms as described, the spur wheels 9 of said mechanisms meshing with pinions l2, l2 respectively, (Fig. 2).

These pinions rotate freely on the fixed shaft 3. Integral with the pinion l2 and rotating about the same shaft 3 is a bevel gear 1 which forms part of the differential gearing [3. The other parts of the differential gearing are the bevel gears 8, l9 and II. Gear 8 is integral with pinion l2 and rotates with it about the shaft 3. The gears I0 and H are mounted on a disc 33 which is joined to the gear wheel ii and rotates with it about the shaft 34 which joins the pinion I2 to the bevel gear 8. Locknuts 35 and 3% keep the Various gears in their proper spatial relationship. It will thus be seen that impulses received by the pinions l2 and li will be transmitted independently of one another to the gear wheel M. For example an impulse received by pinion l2 will be transmitted to the gear I and cause the conjoint rotation of pinion i2 and gear 7. Rotation of the gear I will cause rotation of gears l0 and H which will roll over the surface of gear 8 without causing it to rotate. The rolling of gears Ill and H on the surface of gear 8 will rotate disc 33 and impart an equal amount of rotation to the interconnected gear l4. Rotation of the pinion l2 will produce identical results but in this case the gears l5 and l I roll over the gear 1 without causing it to rotate.

Rotation of the gear wheel It will rotate the gear wheel [5 with which it meshes. The gear wheel i5 is integral with the shaft 3'! which is free to rotate on the spindle l5. Integral with one end of the shaft 3'! is a dog-clutch element i it which cooperates and meshes with a mating dog-clutch element 1 l2 which is provided with a rectangular groove, and which is slidably mounted on shaft IS. A tongue 38 which is rigidly fixed to the shaft I6 is partially inserted in this groove and serves to transmit rotary motion directly from the clutch element H2 to the shaft !6. Likewise, rotary motion received by the gear wheel IE will be transmitted directly to the shaft l6 by means of the intermeshed clutch elements H2 and H3. The dog-clutch elements may be disengaged by moving the element H2 away from the element I I3 and thereby causing the tongue 33 to be projected more deeply into the groove in the element H2. When the clutch members are completely disengaged the spindle it will be free to rotate without being checked by the mechanism which actuates gear l5 and normally prevents the spindle from rotating independently.

In order to disengage the clutch members the register is provided with a rotatable shaft 39 which is situated below and at right angles to the spindle [6. The shaft is provided at one end with a weighted lever 82 which is rigidly attached to the shaft. Lifting of the lever 82 will cause rotation of the shaft 39. Rigidly attached to the shaft 39 are a number of flat plates 69 on each of which is mounted a pair of spaced pegs 4|. The lip 42 on the clutch member l I2 extends into this space between the pegs. The pegs are also ment with the toothed wheel 22 is controlled by so situated on the plates 0 that rotation of the shaft 39 by lifting the lever 82 will cause the pegs to move toward the axisof the shaft -39. As the pegs move toward this axis they will carry with them the lip 42 and will ultimately cause the clutch 'member 2 to be withdrawn completely from the clutch member I I3.. Reversal of the rotation of the shaft 39 will of course cause the clutch members to be re-engaged.

The spindle I6 is provided at one end with a digit disc I! which isrotated one-tenth of a revolution for each impulse received.

On'its end remote from the digit'disc. l! the.

spindle l6 carries a snail cam |8 (Fig. 3) engaged by a follower I01 on a lever |9 urged by a spring 20 in the direction to keep the follower I01 in" engagement with the cam |8. The lever I9 is pivoted between its ends at I08 and has pivoted on its end remote from the follower ID! a link I09 presenting a pin 2| adapted to impart stepwise rotation to a toothed wheel 22 which is freely rotatable on shaft 'IB but which is selectively connected through clutch H2, H3 with shaft I 6 to drive a register disc ||ll similar to and partially overlapping the units digit disc IT. The movement of the pin 2| into and out of engagea reciprocatory guide link 24- one end of'which presents an arcuate guide slot 23 in which works the pin 2|.

is connected by the pin 25 to one arm of a U-shaped member I which oscillates about the shaft 43. The other arm of the member H! is connected by the link 26 to pin 21 which is mount- ;ed on the snail cam 8. Consequently rotation of the cam I8 will cause 'reciprocatory motion of the guide link 24. As viewed in Fig. 3, the cam l8 rotatescounter-clockwise. As the follower rises under the action of the cam IB-the-spring 20 is stretched and the pin 2| is constrained, un-

der the combined control of the cam l8 and the a guide link 24, to vacate an interdental space and to enter a succeeding interdental space of the toothed wheel 22. When the peakof the cam I8 .,passes beyond the follower I01 the follower dropsinto the root l8 of the cam under the action of the spring 20 on the lever l9, which latter is thus forcibly rocked and imparts'a step of rotation equal to one-tenth of a revolution to the toothed wheel 22 through the medium of the link I09 and the pin 2|. A pair of detent pins 30 onthe guide link 24 co-operate with the toothed wheel 22 in order positively to lock the latter during the in tervals between successive steps of rotation of the toothed wheel 22; As will be understood from an examination of Figure 3, with cami|8 being driven by shaft I6 in a counterclockwise direc-' tion, pins 30 will be moved about a tooth of wheel 22, and pin 2| operating in guide slot 23 will .not engage wheel 22. Pins 30 will be movedto the right as viewed in Figure 3 until the pin 21 on cam l8 reaches a position in. a line horizontal with the shaft l6. 7 Continued rotation of cam l8 in a counterclockwise direction will cause pins- 30 to move to the left and this movement will continue until the pin 21 on cam |8 assumes'aposition at the left of shaft I6" and in alposition substantially horizontal with respect to shaft I6. During this movement pins. 30 will be moved completely, free of wheel 22 and pin 2| will be moved into a position between two teeth of wheel 22. At the time when pin'21- is in a horizontal position with respect to shaft and to the left thereof, follower andv cam |8 arein such a position that follower may beoperated by. a.

The other end of the guide link 24 spring 20, to assume the Zero position with the follower ID! in the root |8 of the cam, as the follower moves over the peak point of cam" I8, to thus cause pin 2| to rotate wheel 22 as desired; Upon further rotation of cam I8; the pin 21'will now be moved toward the right, pin 2| will be moved out of engagement with wheel 22 and pins 30 will consequently be moved to a position to engage wheel 22'to thus hold wheel 22 in its new posi- ,tion until the above cycle is repeated. 32 denotes a guard'plate secured on the shaft I6 and adapted to guard or shield the projecting end of the frollower'pintl as the follower I0! drops over the peak and into the root of the cam |8. 'When the cam I8 is in the angular setting in which its root depression |8 is engaged by the follower I01 the Zero digit is exhibitedby the disc The pin 21 carries a roller 28 which co-operates in the rotation of the pin with a circular group of electric contacts 29 (Fig. 2) adapted tocontrol a large remotely disposed public indicator,

Mechanism similar tothe transfer mechanism connecting the shaft l6 of the units register disc with the shaft I6 of the tens register disc is.

interposed between the shaft l6 and the shaft H5 of a hundreds register disc, and is repeated for each subsequent register disc required.

All of the register discs are zeroized simultaneouslyby raising a weighted master lever 82,.

snail cams |8 rotates said cams with their shafts and .digit discs in a clockwise direction until the cams come to rest with their root depressions I8 engaged by the associated followers ID! on the levers I9, in which angular settings of the cams the digit discs exhibit their zero digits. During the. zerosetting movement of anyone group of parts. l9, 2|, 24, etc, the associated wheel 22 of the succeeding register disc is held by pins 30 but this has no effect upon the register disc associated with the wheel 22 due to the declutched position of the clutch H2 and 3. f

I claim:

1. A mechanism for transferring stepwise impulses from a register disc of lower order to one of higher order, which comprises a cam rotated by said register disc of lower order,. a toothed wheel capable of rotating said register disc of' a.

higher order, a spring-pressed lever actuated by saidcam and linked to apinengageable with the toothed wheel, areciprocating guide link, said pin being also under the control of said reciprocatingguide link, means for actuating said reciprocating guide link concurrently with the cam,

the conjoint effect of the spring-pressed lever V and the reciprocating guide link being such as to impart a stepwise rotation to said toothed wheel to rotate the register disc of higher order when the register disc of lower order has been rotated a predetermined amount. a

2; A mechanism as claimed in claim 1 in whic the reciprocating guide link carries detent means for preventing the rotation of the toothed wheel during the intervals between the successive steps of rotation of said toothed wheel.
