Provided on the Fig. 5 is a fragmentary view similar to bar 3 1 are series of (latent springs 37, a head Fig. 2 illustrating the parts of the invention 38 of each of which is dlsposed opposrteone 50 in a difierent posltion, of the gears 15 for a purpose to be described later. Rotatable on the shaft 35 are a series of drive pinions 40, each of these pinions engaging with one of the carr -over discs 17 of a numeral wheel 12 so that or each revolution of this numeral wheel the gear 15 of the next highest numeral wheel will be turned to bring into view a new digit on said next wheel.
Slidably mounted on the shaft 36 is a pair of cam-carrying slides 45 (Figs. 2 and each of which has an upper body portion 46 and depending ends 47 and 48. Coiled about the shaft 36 between the slides 45 is a compression spring 49 which is adapted to hold these slides separated from each other. Extending from the slide ends 48 are finger lugs 50. Also provided on the slide ends 48 are pins 51 which limit the movement of the slides tods each other for a purpose to be decrmed in opposite walls of the frame 7 at opposite points therein are pairs of holes 53 and 54 (Fig. 8). Secured in lower portlons of the slide ends 47, and slidable through suitable apertures in the rockable frame arms 32 andfi are looking pins 55 which are adapted to be urged into either of the pair of holes 53 and 54 oy the spring 49. Also provlded. on the slide ends 47 are cams 58, the purpose which will be described later.
Swingable on the shaft 36 are short arms 66, free ends of which are connected by a bar 61 extending across adjacent to the pinions 40 and having a series of pinion positioning Imgers 62 provided thereon, one of which is disposed opposite each of the pinions 40. In the normal operating position of the resettable register 10, the bar 61 rests upon upper faces of the cams 58 with the jaws 62 out of contact with the pinions 40 (see Fig. 1) Extenddownwardly from bar 61 are cam pms 63 (Fig. 6) which are disposed ad acent to cam surfaces 64 of the cams 58.
Extending inward from opposite points on the frame 7 are stops 65 which are adapted to engage the bar 61 to limit downward swinging of the pinion mechanism 14.
Mounted on inner faces of the arms 32 and 33 are leaf springs 66 which bear against the arms 60 and urge these downwardly. The side arm 32 has a rearward extension 70 to which is pivotally connected a link 71 having a slot 7 2 in its upper end which is adapted to receive the pin 27 on the arm 26.
The casing 7 has a door opening 75 which is adapted to be closed by a door 76 which may be hin edly mounted on the frame 7 as shown in Fig. 1. The door 76 is adapted to be secured in closed position by a suitable lock 77.
The operation of my invention is as foliows:
The control device is particularly adapted to be set so that after a given number of revolutions of the shaft 5 this shaft will belocked against rotation until the door 76 is opened and the descending register reset. Each time the descending register is reset, the indicia wheels 12 are arranged so as to indicate the number of rotations which the shaft 5 may make before the device again locks this shaft. The notches are arranged so that this looking occurs when the descending register 10 indicates zero. That is, when zero is indicated by all the indicia wheels 12 the notches 25 are aligned to receive the comb 19 and permit the shaft 18 to turn and thereby lock the shaft 13, as shown in Fig. 6, and consequently the shaft 5.
To reset the descending register 10 and unlock the shaft 5 the proper key must be inserted in the lock 77 and the door 76 opened. The finger lugs 50 are now engaged between the thumb and forefinger and pressed together as shown in Fig. 5'so as to compress the spring 49 and withdraw the locking pins from theholes 53 in the casing 7. This move ment also brings the cam surfaces 64 against the pins 63 so as to swing the arms 60 and bar 61 upwardly, as shown in Fig. 6, so that the pinion positioning fingers '62 engage the teeth of pinions 40 and align these pinions while they are still in mesh with the gears 15. it is to be noted that at this time the spring detents 37 are out of engagement with the gears 15 as shown in Fig. 6.
After the finger lugs 50 are moved together as above described, the frame is swung downwardly about the shaft 31 to the position in which it is shown in Fig. 7 which removes the pinions from mesh with the gears 15 and swings the spring detent heads 38 into yieldable engagement with the teeth of these gears. When the drive pinions mechanism 14 is thus positioned, the pins 55 are disposed opposite the lower holes 54 formed in casing 7 so that when the finger lugs are released, these pins are urged into the holes 54 by the spring 49. At this time the finger In 50 extend into the door opening 75 (as s own in Fig. 7 by the broken line 90) so that the door 76 cannot be closed until the pinions 14 have i been returned to meshin engagement with the gears 15. When the h nger lugs 50 are released to permit the pins to extend into the holes 54, the cams 58 no longer support the pinion positioning fingers 62 in aligning engagement with the pinions 40, but these fingers are retained in this position by the stops against which end portions of the bar 61 now rest as shown in Fig. 7.
The indicia wheels 12 are now free to be manually rotated to indicate any desired number of rotations for the shaft 5. Rotation of these wheels is yieldably resisted by the detent springs 37, which keep the wheels 12 in alignment so that pinions 40 may be readily returned into mesh with the gears 15 when ever this is desired. When the wheels 12 have been properly set, the finger lugs 50 are again gripped so as to pull the pins 55 out of the holes 54 and the pinion mechanism 14 is swung back into the position in which it is shown in Fig. 6 in which the pinions 40 mesh with the gears 15. The ins 55 are now opposite the holes 53 into which these pins extend when the finger lugs 50 are released by the fingers. When the slides 45 are separated by the spring 49 the bar 61 is permitted to swing by gravity directly into its normal position, (as shown in Fig. 1) in which the fingers 62 are out of engagement with the pinions 40. The finger lugs 50 are now disposed out of the door opening 7 5 so that the door 76 may be closed and locked.
It is to be noted that when the pinion drive mechanism is swung downwardly, as shown in Fig. 7 to free the gears 15 from the pinions 40, the link 71 is moved upwardly so that the bottom of the slot 72 engages the pin 27, swings the shaft 18 to withdraw the fingers 20 from the notches 25 and thereby unlocks the disks 16 and shaft 5. When the indicia wheels 12 have been reset, the notches 25 will not be in alignment so that when the mechanism 14 is swung back into its position with the pinions 40 meshed with the gears 15, certain of the fingers 20 will contact and ride upon the peripheral surface of the discs 16 so as to retain the locking mechanism connected to the shaft 18 in non-locking position until the descending register 10 again indicates zero.
It is thus seen that I have provided a control device in which the drive pinions are brought into alignment before they are moved out of mesh with the indicia wheel gears; in which the door may not be closed until the drive pinions have been turned into mesh with these gears; and in which the drive pinions are locked in alignment while they are being moved between meshing and non-meshing positions. It is to be further noted that the same mechanism which aligns the pinions to permit resetting of the register also yieldably retains the indicia wheels against accidental rotation while the pinions are out of mesh with the indicia wheel gears and releases these wheels when the pinions are again brought into meshing relation with said gears.
It is further noted that my device embodies a control means for the register drive when the pinions are removed from mesh with the indicia wheel gears for resetting .the register.
