KEY HOLDER Filed Aug. 9, 1934 Y I II E 214M111. an m WITNESS: Hls ATTORNEYS Patented July 14, 1936 UNITED STATES PATENT OFFICE 9 Claims.

My invention relates to key holders, and has among its objects and advantages the provision of a novel key manipulating construction.

In the drawing:

Fig. 1 is a top plan view;

Fig. 2 is an end view indicated by the of Fig. 1;

Fig. 3 is a sectional view along the line 3--3 of Fig. 1;

Fig. 4 is a sectional view along the line 4--4 of Fig. 3; and

Fig. 5 is a perspective view of a portion of the device.

In the embodiment selected to illustrate my invention, I make use of a case comprising a shell I0 of sheet material bent to provide a U-shaped configuration in cross section, as indicated in Fig. 2. Within the shell I0, I mount a similarly shaped member I2 having its bight l4 fastened to the bight I6 of the shell Ill through the medium of ears I8, see Fig. 3. These ears I8 comprise integral parts of the bight I6 extending through openings 20 in the bight I4 and bent over.

The flanges 22 of the shell III are arranged in parallel relation and the flanges 24 of the member I2 are similarly arranged with respect to the flanges 22. These flanges function as partitions and provide three channels of equal proportions. Between the flanges 22 and 24 I mount three keys 26 of conventional design, which keys are ar ranged to be housed within the channels defined by the flanges, see Fig. 3, or shifted to an operating position as indicated in dotted lines in the same figure.

I connect a tubular member 28 with the

flanges

22 and 24 near one end of the case for pivotally mounting the keys 26. This tubular member is supported within openings 39 in the

flanges

22 and 24, and has its ends arranged flush wivh the outer surfaces of the flanges 22. Screws 32 are screwed into the threaded interior 34 of the tubular member 26, so that the heads of the screws 32 bear against the flanges 22 and prevent endwise movement of the tubular member. Each key 26 is provided with a spring 36 for shifting its respective key from the full line to the dotted line illustration in Fig. 3.

Referring to Fig. 5, one end of the spring is anchored within a small loop 38 comprising an integral part of its respective flange, and coiled about the tubular member 28. The opposite end of the spring is bent to provide a hook 4|] arranged to connect with its respective key 26 in a manner illustrated in Fig. 3. One of the flanges 24 is provided with two of the loops 38, so that the three line 2-2 springs illustrated are anchored to the two flanges. In connecting the three springs with the two flanges 24, I eliminate the necessity for punching out portions of the two flanges 22.

I provide spring clips 4| for retaining the keys 26 in the full line position of Fig. 3 against the tension of the springs 36. In Fig. 5, I illustrate one of the spring clips 4| in detail. The clip comprises a single sheet of resilient material bent back upon itself at 42 to provide two flange parts 44 arranged in spaced relation and pivotally mounted upon a shaft 46 extending through the

flanges

22 and 24, and riveted at its ends as indicated at 48 in Fig. 1. The flanges 44 of the spring clip illustrated in Fig. 5, are housed snugly between the

flanges

22 and 24 on its respective side of the shell I0 but arranged to be moved freely about the shaft 46 as its axis. The flanges 44 are cut away at 50 to provide two resilient fingers 52 arranged closer together at 54 than the flanges 44 and bent to provide ledges 56.

Each of the fingers is bent outwardly at 58 to provide angular guiding parts 60 arranged to guide the key to a position between the fingers when it is pushed inwardly. In-operation, the key is pressed inwardly between the two parts 60 associated with that key until the latter is stopped by the ledges 56. At this time, the key is firmly pinched between the fingers 52 due to the pressure of the fingers caused by theirengagement with the flanges, see Fig. 4. The frictional condition is such that the key is firmly retained against the tension of its associated spring 36.

To release the key, the clip associated with a predetermined key is actuated by pressing inwardly on the surface 42, which lifts the key sufficiently far to bring the angular parts 6|] out of binding engagement with their

respective flanges

22 and 24. As soon as the clip has been shifted sufiioiently far toassume the position of the detailed showing of Fig. 5, the spring 36 will throw the key to the dotted line position of Fig. 3.

Each spring clip 4| is provided with a spring 62 coiled about the shaft 46 with one end attached to its respective spring clip 4| and the opposite end bearing against the bight I6 or I4.

' These springs are of suflicient strength to shift the clips to the position of Fig. 3 when the keys are not associated therewith.

In Fig. 5, I illustrate the flanges 44 as being provided with an edge 64 arranged to engage the bight I4 or I6 to limit the movement of the clip in the releasing direction. Similarly, the edge 66 limits the movement of the clips in the retaining direction.

Without further elaboration, the foregoing will so fully explain my invention that others may by applying current knowledge readily adapt the same for use under various conditions of service.

I claim:
