COUNTER.

Patented Mar. it, 191C.

Application filed June 8, 1909. Serial No. 500,816.

To all tohom it may concerto:

Be it known that I, CURTIS Hussnr Verona, a citizen of the United States, re-

siding in the city of Hartford, in the State of Connecticut, have invented certain new and useful Improvements in Counters, of which the following is. a specification, reference being had to the accompanying draw-- ings, forming a part hereof.

This invention relates to counters or registers which are adapted to have their number wheels set back to zero from time to time and has for its object to provide improved devices to accomplish such setting back, which shall ofier little resistance to the ordinary operation of the counter and shall not be liable to such interference between the working parts as to prevent the proper operation of the counter. The setting back of the number wheels generally involves, in some way, disconnection of the transmission mechanism by which the complete rotation of any number wheel in the seriesf i's made to effect a forward movement Various means have been devised for accomplishing such disconnection of the transmission mechanism during the setting back of the number wheels, but such means enerally involved considerable complication in structure, uncertainty in operation, and liability to become tied-up, so that the counter cannot operate. In accordance with the present invention, however, the result'is accomplished by providing, in the transmission mechanism, two members which move together duringthe ordinary operation of the counter, while one of the members is free to move relatively to the other during the setting back of the number wheels. Preferably the transmitting pinion itself is made in two parts with a ratchet and pawl connection which compels movement of the two parts together during regular operation and permits movement, during the operatlon of setting back, of one of the parts with respect to the other part.

The invention will be more fully explained hereinafter with reference to the accompanying drawings, in which, it is illustrated as embodied in a convenient and practical form, and in which-- Figure 1 is a plan view showing the counter in operative relation with a shaft,

the rotations of which are to be counted or registered. Fig. 2 is a view in end elevatlon, as seen from the right hand in Fig. 1.

Fig. 3 is a view on a larger scale, partly in longitudinal, central section and partly in elevation, of the improved counter. Fig. 4 isa detail view in section on the plane indicated by the line H of Fig. 3, looking in the direction of the arrows. Fig. 5 is a detail view in section on the plane indicated by the line 55 of Fig. 3, looking in the direction of the arrows. Fig. 6 is a detail view in section on the plane indicated by the line 66 of Fig. 3, looking in the direction of the arrows. Fig. 7 is a detail partial View in section on the plane indicated by the line 7-7 of Fig. 3, looking in the direction of the arrows.

It will be understood that although the planes of section of Figs. 5, 6, and 7 are indicated in Fig. 3 as widely separated, this is merely for clearness and that the several planes of section might be so located as to show the same transmitting mechanism.

In Figs. 1 and 2 a suitable casing a is shown as supporting a shaft Z), the rotations of which are to be counted or registered by the counter or register 0 which is also supported in the casing a and is actuated from the shaft 6 through suitable caring b, 0. Several number wheels cl, 0'! d &c., are shown as mounted to rotate upon a shaft 6 which, in Figs. 1 and 2, is shown as having applied to it a key 6 for resetting. The casing of the counter is shown as made up of a series of short'cylindrical shells f, &c. which are suitably fitted together and, exceptin the first, are suitably provided with sig t openings, as at f*, through which the numbers on the peripheries of the number wheels cl are exhibited. The gear Wheel a, in the construction shown, is mounted to rotate upon the shaft 6 and drives a sleeve 0 which, upon a flange c", carries spring pressed pawls c. The latter engage internal ratchet teeth 0 (Fig. 4) of the first or units numberwheel d, movement in this manner being imparted from the shaft, the rotations of which are to be counted or registered, to the series of number wheels.

The details of construction thus far referred to are such as are in common use and, not being involved in the operation of the improved mechanism, except as hereinafter indicated, need not be described more g I 950,5e6

means for imparting motion to the first number wheel of the series might be employed in place of the means which have been generally described above.

Each of the number wheels (Z, cZ', (Z 8:0. is mounted for rotation upon the shaft 6 and is suitably constructed to impart movement, through the transmitting mechanism, to the next preceding number wheel and to have 10 movement imparted to it through the transmitting mechanism from the next succeedingnumber wheel. As shown, each number wheel, as d, is chambered, as usual, in its left hand end to form an internal locking ring g having a notch g, and with teeth 9 to cooperate with the transmitting gear. Each number wheel, as d, 03 &c., excepting the first wheel d, is also chambered, as usual,'in its right hand end and formed with an internal gear h for cooperation with the transmitting gear. Except as hereinafter indicated, the transmitting gear is formed as usual, being mounted for rotation upon a shaft i carried by suitable hangers, and

having a threetoothed locking pinion 7: to

cooperate with the locking ring g, a sixtoothed driving pinion 7c cooperating with the driving teeth 9 of the preceding number wheel, and a pinion Z which meshes with the internal gear 12, of the succeeding number wheel. The transmitting gear, however, whether made in the form shown or in some other suitable form, comprises two independent members, one of such members in the present construction consisting of the pinions k and 7c, and the other of such members consisting of the pinion Z. These two independent members are arranged to be coupled so as to move as one piece during the ordinary operation of the counter, while the driven member is permitted to move independently of the other during the operation of setting back the number wheels.

Any convenient means for thus coupling the i two members may be employed. As shown in Figs. 3 and 7, the member 7a, is, is chambered, as at 10 in its end next the member Z, and is formed with internal ratchet teeth, as at W, which are adapted to be engaged by spring pawls Z mounted on a flange Z of the member Z.

The supporting shaft 6, in the construction shown, is made use of as a resetting shaft and a pawl and ratchet coupling is arranged between such shaft and each, number wheel. As shown in the drawings, particularly in Figs. 3 and 6, in order to reduce strain on the pawl and to avoid wear on the shaft, there is keyed upon the shaft in proper position in relation to the corresponding number wheel a single toothed ratchet wheel or cam m adapted to be engaged by a spring pressed pawl n carried by the corresponding number wheel. During the ordinary operation of the counter, the pawl n slips idly over the cam or single toothed ratchet wheel m, but when the shaft 6 is rotated in the same direction the pawl. will engage the ratchet wheel.

t will now be understood that in the operation of the counter each number wheel effects, in the matter indicated, the step by step forward movement of the neztt succeeding number wheel, the transmitting mechanism then operating like the ordinary solid transmitting gear. It will also be seen that when the number wheels are to be set back to zero, the shaft 6 is rotated in the same direction of rotation as that of the number wheels during the ordinary operation of the go counter. in such rotation of the shaft it will, through the toothed disks m and the pawls 11, pick up the number wheels as the tooth of the disk m engages the corresponding pawl and will rotate each number wheel 35 in a forward direction so long as the rotation of the shaft is continued. Since the pawls n are similarly placed on the several number wheels, each number wheel will be rotated more or less, according to the position in which it was left at the end of the ordinary operation of the counter, until all of the number wheels show the same figure at the sight openings and then all of the number wheels may be rotated together until the zeros on the number wheels stand at the sight openings. During this movement of each number wheel, the corresponding pinion Z, being'now the driven pinion instead of the driving pinion, will rotate freely with respect to the member is, 70', the pawls Z slipping idlyover the internal ratchet teeth is without disturbing the member is, 70, which will be held from rotation by the locking ring g, and inasmuch as no wheel is turned beyond the zero point, no movement of the member la, 70 will be occasioned by the movement of the corresponding number wheel.

It will be obvious that the details of construction and arrangement may be varied as required by the construction of the counter and that the invention, therefore, is not limited to the details of construction shown and described herein.
