:"51 through the lamp and battery is open and the lamp is not illuminated, while the circuit is completed automatically yand the lamp is illuminated when the candle light is lifted oli the supporting Surface. 1U One object of thepresent invention is the pro- M provision of casing contains the battery,

T" is in constant electrical contact with one termi' vto 35, tact tends,k normally, to

the lower marginal visionrof correlated features for simplifying the construction, increasing the efficiency and cheapening the cost of manufacture of such candle ,lights over ythose heretofore known, as well as rendering the same more convenient and simple to operate.

- Another object oi the invention isto provide a candlelight so arranged that it may' selectively -be set to give a continuous light or become illuminated only when raised off its support, automatin cally extinguishing itself when its base is rested upon a supporting surface.

Still another object of the invention is the a candle light circuit controlling mechanism, the inherent principle of which adapts itself to both conductive and non-conductivebattery containers.

In accordance with the invention, a tubular oneA terminal of which nal of a lamp while' the other battery terminal is in constant electrical contactwith the movable contact of lacir'cuit closure. The movable conbe in circuit making engagement with a fixed contact in constant eleo-` trical connection with the other lamp terminal. In its normal circuit closing position the movable' contact is disposed, at least in part, outwardly of surface of the base of the candle light so that when the base rests upon a supporting surface the movable contact is held away from the Xed Contact and the circuit is interrupted., Provision is also made for permanently completing the .circuit by movement or displacement of the circuit closing structure.

These and other objects of the invention and the means for their attainment will be more apparentfromthe following detailed description, taken in connection with the accompanying drawings illustrating various mbodiments by which the invention may be realized, and in which: f

Figure el is a bottom view of the circuit controlling mechanism taken on the line 4-4 of Figure 1 and looking in the direction of the arrows.

Figure 5 is a transverse sectional view taken on the line 5 5 of Figure 1 and looking in the direction of the arrows.

Figure 6 is a View similar to Figure l, but showing a modification of the candle light structure.

Referring now in detail to the several figures of drawingsv and iirstV adverting to Figures 1 through 5, there is shown a metallic and preferably cylindrical battery casing 10 having its upper end 12 tapered and reduced in diameter to simulate the usual form of the upper end of a candle the extremity of the part l2 being turned over in a transverse plane to form a liange 14 dening, conveniently, a circular hole receiving a lamp socket 16 for the base 18 of a lamp 20. Near its lower end, the casing 10 is pressed outwardly to form a bead 22 and at its lower extremity it is threaded, Vas at 24, for the reception oi a caplike, or at least a generally cup-shaped, member 26 embodying the circuit closing element. The bottom of the rcap 26 is formed with an opening 38 which may be said to be defined by the inwardly directed bottom iiange 39.

In the illustrated embodiment, the battery is shown as formed of two individual cells 28 and the central or carbon terminal oi the battery is adapted to be maintained in constant contact with the central terminal of the lamp base 18 by means of a battery positioning element, preferably resilient, in the form of a coil spring 32 which is carried by the cup-shaped closure 26 and is conveniently utilized to cooperate and in a sense function as a part of the circuit closing structure.

The coil spring 32 is out of Contact with the walls of the container l0 and/ or threaded end 24 thereof and is mounted, by means, say, of the eyelet 36, upon a disc of insulatory or nonconductive material 34 resting on the ange 39. The disc 34 is, preferably, of a diameter to fit fairly snugly within the bottom of the cup-shaped cap 26 and closes thereby the opening 38, which is preferably circular and formed therein. In other words, the wall of the cup-shaped cap 26 is turned inwardly as a flange 39, which flange 39 denes the opening 38 in the bottom of the cap. Conveniently, the battery positioning element 32 rests upon a disc, preferably of wear resistant material 40, such as metal, which is carried by the insulatory disc 34 and is of a diameter less than the diameter of the disc so that when held in place by the rivet 36, it is held out of contact with the walls of the cap 26, although as will hereinafter more fully appear, it is of a diameter sufficient to contact with and bridge or close the open bottom end of the casing 10, as seen in Figure 3, and permanently complete the circuit through the lamp. At one portion of its perimeter, the disc 34 is formed with a notch 42 and a movable contact member moves within this notch from an open circuit position out of contact with the casing 10 or any part in electrical connection therewith to a closed circuit position in contact with the flange 39 which, of course, is in electrical connectionwith the casing 10. As illustrated, the contact member is formed by a transversely extending nger 44 mounted upon the extremity of a longitudinally extending arm 46 carried upon a` ring of conductive material 48, which is secured to the disc of insulatory material 34 andin electrical connection with the battery positioning element 32 by which the circuit between the contact 44 and the negative terminal of the battery 28 is completed. As shown, the ring 48 is provided with a radially extending supporting part 50 which, at the center of the ring 48, is secured by the rivet 36. The conducting ring 48 is formed of resilient material and is so bent as tonormally stand away from the disc 34, as shown in Figure 2, whereby the contact 44 tends to be in engagement with the flange 39 on the casing. When the ring 48 is pressed upwardly, as viewed in the drawings, the contact 44 is moved away from the flange 39 and the circuit is broken.

The circuit of this candle light is traced as follows:

From the central terminal 30 of the battery the current flows to the central terminal of the lamp base 18 through the lament of the lamp to the peripheral terminal of the lamp base 18, thence to the socket 16, and from the socket 16 through Vthe metallic casing 10 to the threaded lower end 24. The conductive cap 26 is in electrical connection with the threaded lower end 24 and hence the circuit vis completedthrough the cup-shaped closure, the flange 39 thereof, the contact 44, arm 46 and ring 48, eyelet 36 and battery positioning element 32 to the other terminal of the battery.

Obviously, the casing 10 need not be of conductive material but may be of non-conductive material, for instance, fiber, in which event the cir cuit maybe completed by any metallic strip extending between the socket 16 and the threaded end 24 for engagement either by the cap 26 or the metallic disc 40.

The bead 22 on the casing 10 is utilizedto i'lx the position of a base for the candle so as to give the efect of a candle stick, for instance. This base may take any convenient form and, as indicated, it is of relatively large diameter, as at 50, having a central upwardly extending tubular part 52 telescoping over the casing 10 below the bead 22, which positions the casing 10 with respect to the base. The two parts may, of course, be permanently secured together, as by welding or the like. The bead 22 also xes the positionof the vlifted off the bottom cap, in one sense, with respect to a supporting surface T upon which the base 50 rests. That is, the flange 39 may be slightly above the supporting surface or in contact therewith when the base stands on the supporting surface, but must in no instance be suiiciently above the supporting surface to permit the movablecontact 44 48 to move downward suiliciently to bring the contact 44 in engagement with the flange 39.

The parts in open circuit position are indicated in Figure 1. When, however, the candle light is supporting surface T, the inherent resiliency of the ring 48 is suicient to cause the same to move downwardly, as shown in Figure 2, to bring the contact 44 in engagement with the contact 39 to close the circuit, as has been describe-d. g

In some instances, it may be desired that the candle light give a permanent light although resting on a table. As shown in Figure 3, this is accomplished by screwing the cap 26 further on to the threaded end 24, thus bringing the disc 40,

upwardly into contact with the end of the flash-y lightcasing. rIhus the disc 40 short circuits the contact and causes the illumination of the lamp. The circuit then is from the battery positioning element 32 to the disc 40 and from the disc 40 to the casing 10. When the circuit is to be interrupted, it is merely necessary to unscrew the bottom cap again sufficiently to move the disc 40 away from the end of the casing. 1

A modification of the invention is illustrated in Figure 6. At its upper end, thecandle light does not differ materially from that construction shown in Figure 1 except that in the'interest or a nished appearance, the ange 14 iscupped, as shown at 58, so that the clamping flanges of the socket 16 are hidden from view. At the lower end of the candle light, the connection between the two is simplified materially in the interest of manufacture. No bead 22 is formed on the casing 10. Instead, the upper end of the cap 26v is formed with an outwardly extending flange and the base 62 is formed about the central hole which receives the casing 10 with spaced inwardly directed flange portions or a groove 64 receiving the flange 60. The cap 26 and base 62 can thus be readily clamped and secured together and the base 62 is a'ixed to the casing 10 merely by screwing on the cap 26.

' Various modifications will occur to -those skilled in the art in the composition, configuration and disposition of the component elements going to make up the invention as a whole, and no limitation is intended by the phraseology of the foregoing description or illustrations in the accompanying drawings, except as indicated in the appended claims.
