6 Claims. (Cl. 240-642) This invention relates to a flashlight or hand light, and one that is designed primarily for use as an umbrella handle, although it is also adapted for use as an ordinary hand or flashlight. v

An object is to provide an improved construction of this type of device which may employ a plastic or insulating shell or casing, and this shell or casing may be employed as the handle of an umbrella or similar device to readily provide an effective illuminating means for use by a person carrying an umbrella in a storm at night, for example.

Another object is to provide an improved construction and arrangement whereby the circuit to the lamp bulb may be controlled by a slight rocking movement of the enclosure or head carrying the reflector, thus doing away with the ordinary finger switch used in flashlight construction.

With the foregoing and other objects in View, I have devised the construction illustrated in the accompanying drawing forming a part of this specification. it is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.

In this drawing:

Fig. 1 is a longitudinal section showing one form of the device;

Fig. 2 is a top edge view thereof;

Fig. 3 is a detail section showing a slight modification, and

Fig. 4 is a section similar to Fig. 1 showing another modified construction.

Referring first to Figs. 1 and 2, there is shown in these figures an arrangement using a single battery in the chamber 11 formed in the casing 12 preferably of suitable molded plastic material, this casing being open at its upper end for free access to the socket or chamber 11 for insertion and removal of the battery. The battery 10 is of the usual type comprising the central contact 13 and the metal shell 14 enclosed in the outer casing 15 of the usual fibrous insulating material. The open end of the shell or casing 12 is closed by a metal cap 16 including a threaded flange 17 screw threaded on suitable threads 18 on the outer surface of the casing, and at its open end it may be roughened or knurled, as indicated at 19, to provide a better hand grip in applying it to or removing it from the plastic casing 12.

This cap 16 has a central opening 20 in its top wall 21 in which is mounted a metal lamp socket 22 of any provided with an outwardly extending disc 27 having a downwardly extending flange 28 at its outer edge forming a circular electrical contact locatedover the top edge -29 of the zinc shell 14 of the battery and normally spaced from it as shown. The screw shell 22 also extends through an opening at the center and bottom of the tapered wall 30 of the plastic cap or head 31, the bulb 24 being in the cavity formed by this tapered wall, and the upper surface may be provided with a light-reflecting surface 32. At its upper outer rim this cap or head has an outer wall or skirt 33 which extends down over and surrounds the upper portion of the cap 16, leaving the lower portion exposed so it may be readily gripped for application to or removal from the casing, and is spaced therefrom, as indicated at 34, to permit limited relative rocking movement of the head 31 with respect to the cap. Between this cap 16 and the under side of the tapered wall 30 is a light coil spring 35 which holds the head 31 in the normal central position with respect to the cap 16, and thus holds the screw shell 22 and its flange 28 horizontally with the rim of this flange spaced from the upper edge 29 of the metal shell 14 of the battery. The shell or socket 22 may be mounted in the opening in the wall 30 and the end wall 21 of the cap 16 by means of an insulating sleeve 36 as shown in Fig. 1, or directly in these openings as shown in Fig. 3, but it is mounted suificiently loose in the opening 20 in the cap 16 so that the head 31 and the lamp socket or shell 22, together with the circular electrical contact 28, have limited rocking movement with respect to the casing 12 and the cap 16, while the central contact 25 of the lamp bulb remains in engagement with central contact 13 of the battery. The spring 35 holds the head 31 and the contact 28 in the centered or oil position shown in Fig. 1, with the free edge of the contact 28 spaced from the end of the shell 14 of the battery, thus breaking the circuit through the lamp bulb. If the head 31 is tipped laterally in any direction, it brings the edge of the flange 28 into engagement with the upper edge 29-01 the zinc shell 14 of the battery, thus closing the circuit through the light bulb and lighting it. As soon as the pressure on the head 31 is released, the spring 35 will return it to its normal central position and shift the circular contact 28 away from the battery shell 14 and open the circuit to put out the light. Thus no switch of the ordinary type is required, and to operate the lamp all that is necessary is to apply tipping or lateral pressure to the plastic head 31.

It will thus be seen that control of the circuit through the lamp bulb is etfected by movement of the head 31 and only very slight movement is required, as the edge of the circular flange or contact 23 need be spaced only a short distance from the edge 14 of the shell of the battery. It will, of course, be understood that the control of the circuit is by movement of the head 31 and the circular contact 28, and the circuit from the battery through the lamp bulb may be closed either by the contact 28 engaging the shell of the battery directly or through an intermediate electrical conducting means. Such an arrangement is shown in Fig. 4, which may be used with one or more batteries 10, two batteries being shown in Fig. 4 arranged in series. In this case the outer shell or casing 12 is provided with a somewhat larger socket or chamber 111; in which the batteries are located and its upper end is closed by the same metal cap 16 in which is mounted the lamp socket or shell 37 corresponding to the shell 22 in Fig. 1. In this case, however, as there are two batteries used, the circular flange or contact 38 forming a part of the lamp socket 37 and corresponding to the circular contact 28 of the first form, instead of being arranged to engage the free end of the metal shell 14 of the upper battery, is arranged to engage the cap 16 which is electrically connected with the metal shell of the lower battery. Therefore this flange forming the circular contact 38, instead of being curved downwardly as in Fig. 1, is curved upwardly as shown in Fig. 4, with'its free edge normally spaced a short distance from the under side of the end Wall 21 of the cap 145, and this cap is placed in electrical connection with the lower end 39 of the metal shell of the lower battery by a metal conducting strip ltl engaging the cap 16 at its upper end 41 having a curved spring lower end 42 engaging the metal shell 3? of the battery, and also acting as 'a spring means for supporting the batteries at the lower end or the socket 11a to retain the central contact 13 of the upper battery in engagement With the central contact 25 of the lamp bulb. In this arrangement, as the cap 16 is in electrical connection with one element of the battery, the lamp socket or shell 37 must be insulated from the cap 16, and this is shown as eflected by the insulating sleeve 43, it, however, being understood that this sleeve is sufficiently loose in the opening in the cap 16 to permit the small amountof rocking movement required of the plastic head 31 to control the electric circuit through the lamp bulb. The rocking movement of this head in this case brings the free edge of the circular contact'38 into engagement with the under 'sideo'f the top wall'21 of the cap 16, to close the circuit through the lamp bulb, and as soon as pressure on the head 31 is removed the spring 35 will shift this head and the contact '36 back to their normal central positions, with the free edge of contact 38 spaced from thecap 16 to thus bring it to its normal noncircuit-closing position.

.If thisdeviceis used as th'e'handle of an umbrella or the like, the outer shell or casing may be provided "with a suitable socket 44 in its lower end to receive the end of the central rod of the umbrella for'securing it thereto.

It will be seen from the above that this'provides a very simple construction which may be used either as the handle of an umbrella or the like or as a regular type of flashlight; that the light bulb is controlled by simple rocking movements of the head carrying the reflector, which is returned to its non-lighted or off position automatically'as soon as pressure on the head is removed, and that with thisconstruction the usual type ofthu'm'b =01 finger switch is eliminated.

Having thus set forth the nature of my invention, I
