TRANSFER MECHANISM FOR NUMBERIN G R REGISTERING MACHINES.

SPECIFICATION forming part of Letters Patent No. 761,942, dated June 7, 1904. Application filed March 12, 1904:. Serial No. 197,880- (No model.)

To all whom it may concern.-

Be it known that I, LoUIs F. Bnnws'rnn, a resident of Cleveland, Ohio, have invented a new and useful Improvement in Transfer Mechanism for Numbering or Registering Machines, which invention is fully set forth in the following specification.

This invention relates to improvements in transfer mechanism for imparting movement from one wheel to a succeeding wheel of a series, the latter wheel being advanced a step for each complete or partial rotation of a preceding wheel. Mechanisms of this general character are most commonly used in meters and for carrying tens in numbering, registering, computing, and analogous machines.

The object of the invention is the construction in a simple and economical manner of an efficient and durable mechanism of few parts.

In the drawings illustrating the preferred embodiment of the inventive idea, Figure 1 is an elevation showing three number-Wheels. Fig. 2 is a transverse section on line A A, Fig. 1. Fig. 3 is a front elevation of a single number-wheel and its related gearing. Fig. 4 is an elevation from the right, Fig. 3; and Fig. 5 is an elevation from the left, Fig. 3.

Referring to the drawings, 1 is a fixed shaft on which a series of number or digit wheels 2, 3, and 4: are loosely and revolubly mounted. Each of these digit-wheels has connected to one face thereof in any suitable manner a gear-wheel In the other face are two concentric grooves 6 and 7. The rib or land 8, Fig. 5, separating these grooves is broken away at 9, thus forming an open space into which projects a tooth or projection 10, integral with a plate 11, secured to the digitwheel. (SeeFig. 5.) This plate and projection, though herein illustrated as being separate, may be formed integrally with the digitwheel, if desired, and a packing or washer 18,

Fig. 2, may be interposed between the same and gear-wheel 5.

14 represents bars strung upon two rods 12 and 13. Spacing-sleeves 20 between the bars are also strung on the rods. On each of these bars is mounted a disk, (three1515' 15"be ing herein shown,) each adapted to rotate on a short pintle 16 and having a plurality of pins 17 Three pins equidistantly spaced are illustrated, though any suitable number may be employed. The disks and pins constitute pinions having elongated teeth which, as illustrated in Fig. 2, mesh with the teeth of gear-wheels 5 and project into grooves 6 and 7, thereby normally locking the disks and digit-wheels against premature rotation. This feature of the teeth on the pinion engaging teeth connected to one number-wheel and projecting into operative relation with the locking and actuating means on the adjacent wheel conduces to great simplicity of structure and constitutes an important part of the invention.

The operation of the device is as follows: Motion having been imparted to the unitswheel 2 by any suitable means, the same bcgins to rotate, successively exposing at the sight-line the numbers 1 to 0. As the units-wheel revolves from 9 to 0 the tooth 10, carried thereby, engages one of the. pins of disk 15 and rotates the latter a third of a revolution, (this being permitted by the open space 9 in the rib 8.) This turns gear-wheel 5, connected to the tens-wheel, from 0 to 1, the distance of one tooth, and advances said tens-wheel from O to 1, indicating 1O at the sight-line. Likewise as the tens-wheel rotates from 9 to 0 its tooth engages one of the pins of disk thus effecting the revolution of gearwheel 5, connected to the hundreds-wheel 4, and advancing the latter from O to ,1, thus indicating 100 at the sight-line.

As will be evident, the nu mber-wheel of the highest order of tens need not be provided with pinion actuating and locking means. Furthermore, motion may be imparted to the wheel of lowest order in any suitablemanner.

While the arrangement of grooves, rib, and projection as shown is preferred, the function of locking the pinion until rotated by the projection may be performed by the rib 8 alone or by the shoulder 30, forming a recess or opening 31 opposite the projection 10 to permit rotation of the wheel.

Other details of the mechanism may obviously be modified without departing from the invention. Other forms of pinion may, for example, be employed in place of the disk and pins.

hat is claimed is 1. In transfer mechanism, two rotatable wheels, gear-teeth connected with one wheel, a shoulder extending around the face of the other wheel and having a recess or opening therein, a projection or finger on said wheel, a pinion having teeth adapted in meshing with the gear-teeth to pass between thelatter, said pinion-teeth terminating in cooperative relation with the shoulder and projection, whereby the shoulder locks the pinion against rotation and the projection acts to rotate the pinion in the recess in the shoulder.

2. In transfer mechanism, two rotatable wheels, gear-teeth connected with one wheel, a rib extending around the face of the other wheel and having a recess or opening therein, a pinion having teeth adapted in meshing with the gear-teeth to pass between the latter, said pinion-teeth terminating on opposite sides respectively of said rib and in position to be actuated by the projection or linger to rotate the pinion in the recess in the rib.

3. in transfer mechanism, two rotatable wheels, gear-teeth connected with one wheel, a shoulder extending around the face of the other wheel and having a recess or opening therein, a projection or finger on said wheel, a rotatable pinion between the wheels having laterally projecting teeth passing between said gear-teeth and terminating in cooperative relation with the shoulder and projection, whereby the shoulder locks the pinion against rotation and the projection acts to rotate the pinion in the recess in the shoulder.

at. In transfer mechanism, two rotatable wheels, gear-teeth connected with one wheel, a shoulder extending around the face of the other wheel and having a recess or opening therein, a projection or finger on said wheel, a rotatable pinion between the wheels, said pinion comprising a disk and laterally-projecting pins on said disk passing between the gear-teeth and terminating in cooperative relation with the shoulder and projection, whereby the shoulder locks the pinion against ro* tation and the projection acts to rotate the pinion in the recess in the shoulder.

5. In transfer mechanism, two rotatable character-wheels, a gear-wheel connected to one character-wheel, a rib extending around the face of the other character-wheel and having a recess or opening therein, a projection or linger on said other character-wheel, a retatable pinion between the character-wheels, said pinion comprising a disk and laterallyprojecting pins on the disk passing between teeth of the gear wheel and terminating respectively on opposite sides of the rib and in position to be acted upon by the projection, whereby the rib locks the pinion against rotation and the projection acts to rotate the pinion in the recess in the rib.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
