AUTOMOBILE KEY C ASE James Hickey, Portland, Oreg. Application October 28, 1940, Serial No. 363,166

Claims.

This invention relates to pocket key cases or holders of the typev frequently used for auto# mobile keys.

An object of this invention is to provide an improved key case particularly adapted for automobile keys in which each key is separately accessible and may be exposedand moved into outward position for insertion into a lock without disturbing thev remaining keys.

Another object of this invention is to provide an automobile key case which will also have an adjustable time indicating means so that the l owner of the key case, when parking his auto.

A still further object is to provide a practical automobile key container and parking time indicator which will be simple and inexpensive to manufacture and practical and convenient in use.

'I'hese and incidental objects I attain by making my combined key case and parking time'reminder as hereinafter briefly described with reference to the accompanying drawing.

In the drawing:

Fig. 1 is a front-face view of my key case showing the parking time reminder and showing the keys in closed position in the case;

Fig. 2 is a rear-face view of the key case with the plates disconnected and swung apart at one end to reveal `certain members attached to the case located inside and showing the keys all swung outwardly on their pivots;

Fig. 3 is a side elevation corresponding tol Fig. 1;

Fig. 4 is a similar side elevation but with the keys all removed from the case and with one of the connecting members between the faces of the key case shown in vertical section.

Fig. 5 is a fragmentary sectional plan taken on the line 5-5 of Fig. 4 and showing the time indicating hands superimposed above the gear train controlling the positioning of the hands;

Fig. 6 is one-half plan view corresponding to Fig. 1 and one-half sectional plan view similar to Fig. 5, with the keys all shown in open position; and

Fig. 7 is an enlarged sectional'v-view of the mechanism for setting the positions of the hands in the parking time reminder.

The case is formed of two identically-shaped pieces I0 and II, made of sheet brass or other suitable material. Although the two pieces I0 and I I are identical, as will be seen by comparing the front-face piece I0 of Fig. 1 with the rearface piece I I of Fig. 2, the two pieces are secured together in reverse position, that is to say, one of the pieces is inverted prior to being assembled in parallelism with the other, as will be apparent from Fig. 2. Each of these pieces is formed with rounded ends taperingly extended from a substantially circular central portion. The frontface piece I0 is provided with recesses I2 and I3 extending inwardly from opposite edges, and the rear-face piece II is likewise provided with the similar but oppositely-disposed recesses I4 and I5.

The two-face pieces IIJ and II are spaced apart slightly more than the thickness of two keys and are detachably held in this relationship by screws I 6, I6 threaded in the tubular stems of spacer posts I6', I6 which preferably are secured rigidly, by riveting or by other suitable manner tothe rear-face piece II (see Fig. 4). The case when assembled is adapted to hold four keys, Il, I8, I9 and 2li, two keys being carried on each post I6. The posts I6 are of sumciently small diameter to enable them to pass through the usual holes in the handles of the keys thus providing pivotal mountings for the keys. When the keys are to be attached to the case the screws I6 and front-face piece I0 are removed and the keys placed upon the posts I6. Thereupon the front-face piece and screw I6 are replaced.

When placing the keys on the posts I6 each key is so arranged that, when swung into the closed position ofFig. 1, the plane edges of the keys will be outermost and the plane edge of each key will extend across the corresponding recess of the adjacent piece or member I0 or II so that each key will be separately accessible from one recess of the case. Thus, referring to Fig. 1, the slotted plane edge or stem of the keys Il and I9 are accessible from the recesses I2 and I3 of the upper or face member I0 of the case, and, from the other side of the case (see Fig. 2), the keys Il and 20 are accessible from the recesses I4 and I5, respectively of the other face member Il. To move the key Il, for example, in Fig. l, into outward position for use it is necessary only to insert the thumb or forenger in the recess I2 in order to contact the key and swing it out.

In order to facilitate the selection of the keys words designating the respective keysY may be stamped on the key case members l and ll adjacent the recesses in the manner shown in Figs. 1 and 2.

A piece of sheet metal 33,I of the size approximately is illustrated in Fig. 5, with its ends bent substantially at right angles, is secured to the inner side of the front-face member l to serve 'as a partial housing and support for the gears of the parking time indicator. The ends of the piece 33 extend at right angles for a distance equal approximately to the thickness of an ordinary automobile key. f

A circular dial 22 (Fig. 1), graduated like the face of a clock, is located on the outer side of the front-face member concentric with the circular central portion of the member l0. A minute hand 23 and an hour hand 24 are adapted to be rotated on the outside of the dial 22 by the. rotation of a central shaft 25 and sleeve 32 respectively. The manner in which these are rotated will be explained presently. The dial and hands are protected by a suitable transparent covering.

The central shaft 25 has one end extending through the front-face member' ill and the other end extending through the supporting housing 33. The latter end of the shaft 25 is square and a disc 2l and washer 34 are rigidly secured thereon (see Fig. 4 and 7). The minute hand 23 is attached to the opposite end of the shaft 25 outside the face member lil and its dial. The `disc 26 is slightly larger in diameter than the central portion of the case members I0 or il so that the peripheral edge of the disc 2S extends slightly beyond the edges of the members i@ and ll. The edge of the disc 26 may be serrated, as shown in Figs. l and 6, to aiord a better grip for the fingers when manipulating the disc and the setting of the hands 23 and 24. i

A pinion 2l (Fig. 7) is fixed on the shaft 2'5 on the inside of the supporting housing and meshes with a gear 28. The gear 28 and a piniony 30 secured thereto are carried on a shaft 2S supported in the housing and top-face member. Pinion 30 meshes with a gear 3l secured to the sleeve 32 rotatably-mounted on the central shaft 25. The hour hand 2B is secured to the other end of the sleeve 32 on the outside of the dial. Thus the turning of the disc 26 will cause the hands 23 and 24 to be rotated in the same manner and in the same relationship as with the hands of an ordinaryclock. The friction of the gear train associated with the hands will prevent any inadvertent turning of the hands, but the setting of the hands to indicate the time of parking is easily done by turning the serrated disc 2.-

The housing 33 (see Fig. 5) and the gear train contained therein are suiliciently small to permit space at both sides of the housing to accommodate the ends of two opposite keys respectively, and thus my entire key case can be made quite small and will still be large enough to accommodate four ordinary-sized automobile keys. The washer 34 (Figs. 2 and 4), secured tov the outer face of the disc 26 and to the end of the shaft 25,V is preferably of slightly less thickness than an ordinary key so that when the keys are inserted in position, as shown in Fig. 3, there will be a slight bowing of the rear-face piece Il which, due to the resiliency of both face members I0 and Il of the case, will cause sufllcient frictional grip to be exerted to hold the keys in closed position while the key case is being carried in the pocket.
