INDICIA REIGISTERING MECHANISM Filed March 15, 1954 NTOR Y' I A TORNE y United stares Patent QT 2,774,158 Y y INDICIA REGISTERING MECHANISM William Tamoschat, Bronx, N. Y., assgnor to The Zell Products Corporation, Norwalk, Coun.

Application March 1s, 1954, serial No. 416,929 4 claims. (c1. 411-70) printed, engraved, or otherwise decorated with initials,

numbers or symbols; to provide a mechanism which may be set to register the desired indicia without levers or handles extending from the case; to provide a two-dial mechanism which may be operated in one direction to set one dial and in the other direction to set the remaining dial; to provide two dials which are concentrically positioned with respect to each other whereby the outerV dial may operate the inner dial; and to provide a mechanism of the foregoing character which will not add appreciably to the bulk of the object to which it is added.

I accomplish these and other objects and obtain my new results as will be apparent from the device described in the following specication, particularly pointed out in the claims, and illustrated in the accompanying drawing, in which- Fig. 1 is a perspective view of a powder compact employing my registering mechanism.

Fig. 2 is a sectional view of the compact of Fig. l taken in the plan 2 2.

Fig. 3 is a sectional plan view of the compact taken in the plane 3 3 of Fig. 2.

Figs. 4, 5, 6, and 7, are plan views respectively of the top cover (partially shown), the outer dial, the inner dial, and the guide plate.

Fig. 8 is a perspective view of the supporting rim and.

min-or for positioning under the mechanism in the top cover.

The mechanism is shown in detail in Figs. 2 and 3, inside the compact 10, which comprises a lid 12, and a bottom receptacle 14 hinged at 16. Two annular stampings, concentrically positioned, a-re formed into inner dial 18 and outer dial 20. These are positioned inside a plate 22 for guiding the movement of the dials. This is accomplished by forming upstanding rims 24 and 26 in the plate at the inner and outer edges, respectively, of the dials which rims form a seat within which the dials revolve. The plate is prevented from rotating with respect to the lid by an upset portion 28 in the side wall 30 of the lid wall which tits into a conrponding recess 32 in the plate.

The dials are eccentrically mounted with respect to the lid, to position one edge of the outer dial 20, adjacent an opening 34 in the wall 30 of the lid, where they may be engaged either by the thumb nail, or by a pointed tool 2,774,158 ,Patented Dec. 1s, 195e such as the key 36. The outer dial is notched, as at 38,

to facilitate rotation.

The inner dial 18 is caused to rotate by movement of the outer dial. This is accomplished by providing ratchet teeth 40 on the inner edge 42 of dial 20. These engage in one direction a spring biased pawl 44 formed on the outer edge 46 of inner dial 18. The ratchet teeth and pawl comprise the connecting means. The ratchet teeth will cam over the pawl 44, forming a disconnector when dial 20 is rotated in the reverse direction. 1

The inner edge 48 of dial 18 is similarly provided wi ratchet teeth 50 which are engaged in one direction by a spring biased pawl 52 formed in the wall 24 of plate 22. The 'ratchet teeth and pawl comprise the holding means. The ratchet teeth will cam over the pawl 52, forming a release mechanism when the dial 18 is rotated in the opposite direction.

Looking at the dials in the position shown in Fig. 3, it will be seen that the ratchet teeth and pawls are designed to permit outer dial 20 to rotate clockwise individually, but when rotated counterclockwise the ratchet teeth 40 lock against pawl 44, causing the inner dial to be carried thereby. Then it is possible to set the inner dial to the desired position, and thereafter to reverse the movement of dial 20 which will set the outer dial to the selected indicia, Without loss of position of the inner dial. However, should the inner dial start to rotate clockwise, as seen in Fig. 3, the ratchet teeth 50 will lock against pawl 52 of the plate 22 to prevent clockwise motion.

The dials are, in the example illustrated, provided with letters of the alphabet to permit selected letters from inner and outer dials to be visible through apertures 54 and 56, respectively.

The bottom of the plate 22 may be covered by a mirror 58 supported by an annular rim 60 secured firmly to the wall 30 of the lid. The dials and plate may be made of thin metal stock which permits pawls 42 and 52 to be formed in the stamping operation. Slot 62 may be formed in the plate 22 to facilitate the spring action of pawl 52, while slots 64 may be provided to aid in drawing the wall 26 and limiting the friction between dial 20 and the plate 22.

While the registering mechanism is shown as part of a powder compact, it is apparent that the mechanism may be incorporated in other devices where numbers or symbols may be used in place of letters.

I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention, and, therefore, Iclaim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to attain these objects and accomplish these results.

I claim:

1. An indicia indicating mechanism comprising a first and second dial mounted on the same axis, and a stationary member; each of said dials containing a plurality of indicia thereon; a cover for said dials containing means for viewing certain of the indicia on said dials; connecting means interlocking the rst and second dials to cause both dials to rotate as a unit when the first dial is rotated in one direction, said connecting means including a disconnector for unlocking the two dials when the iirst dial is rotated in the :reverse direction; holding means interlocking the second dial and the stationary member for preventing rotatiQn of the. second. dial when, the, first dial, is rotated in the `reverse direction, said holding means including a releasing mechanism for unlocking the second dial from the stationary 'member'. when the first second dials are rotating in the same direction-r 2.
