Application tiled November 18, 1924. Serial No. 750,602.

One of the principal objects of this invention is to provide a small ornamental and readily portable self contained electric lamp adapted for household use.

Another important object of the invention is to provide a small portable self contained electric lamp with means whereby the lamp circuit will be interrupted when the lamp is released by the hand and placed on a table 0 or other support, and will be complete or closed when the lamp is lifted by grasping it at a certain point.

Another object of the invention is to provide means whereby' the lamp circuit may be permanently closed so that it will not be aiected when the lamp is released by the hand and placed on a. table or support.

Still another` object is to provide means whereby the lamp circuit. will he automatically closed, to provide illumination, when the lamp is inverted.

The lamp is illustrated in the drawings in the :torm of a candle stick, but of course itA will be understood that it may be made up in any suitable form.

In the drawings, Fig. l is a vertical section through the lamp;

Fig. 2 a side elevation showing the lamp being lifted from a support;

Fig. 8 a side elevation showing the lamp inverted;

Fig. 4 a bottom plan View of the lamp;

Fig. 5 asimilar View upon a larger scale, showing the battery retaining plate removed; and

F ig. 6 a fragmentary side elevation of they lamp standard, parts being shown in secf tion.

.Referring to the parts by numerals, 1 designates the base of the lamp which is hollow and in the form of a wide, fiat, inverted cup. A straight, tubular standard 2 is rigidly supported by the base and has a lamp socket 3 mounted in any suitable manner at its upper end. The socket 3 is adapted to have4 the plug of an electric lamp bulb 4 threaded into it. A Hat electric battery 5 is located within the hollow base of the lamp and is held therein by a retaining plate 6 which closes the under side of the base. The plate 6 is held in place by means of a pair of diametrically located studs 7 carried by brackets 8 which are secured within the base. The studs 7 are formed with heads and with reduced portions or necks which reduced portions are adapted to engage in the reduced ends of a pair of key slots 9 formed in the retaining plate.

A block of insulation 10 is secured within the base at one side of the battery and has a xed contact 11 mounted thereon. This contact is in the form of a metal strip insulated from'thc lamp base and inturned at its free end. as at 12 to form an abutment. One of the contacts 13 ot' the battery is adapted to abut the shoulder 12 of the fixed contact 11 and the other battery Contact 14 bears against the inner wall of the base. The corners of the battery tit snugly within the lamp base and the contacts are thereby held firmly in their proper positions. A circuit wire 15 is connected to the 'fixed contact, leads upwardly into the tubular standard and is coiled as at 16. The upper end of the wire 15 is connected to the lower end of a brass rod 17 which extends upwardly within the standard. A cylindrical insulation plug 18 is secured to the rod 17 adjacent its upper end vand the lower end of the rod is extended through a similar insulation plug 19. The plug 19 is slidable' over the rod 17 and both plugs are freely slidable within the standard and serve as guides for the rod 17 and to hold it out of contact with the standard.-

A lifting and circuit closing sleeve 20 enside ofthe standard 2. A screw 21 extends inwardly from the sleeve 20 and through a vertically extending slot 22V formed .in the standard and said screw is threaded into the circles and is adapted to slide upon the outv plug 19 to lock said plu to the sleeve 20.

The rod 17 is formed wit 1 a thread extending down from its upper end for a material distance and the plug 18 is screwed thereon. Below the plug 18 a collar 23 is threaded upon the rod 17 and serves as an adjustable abutment for a coiled spring 24 which encircles the rod and is interposed bet-Ween the said collar and the plug 19. In the usual position ofthe sleeve 20 and plug 19,-the screw 21 rests in the lower end of the vertical slot 22. In this position of the sleeve,

the rod 17 is supported by the plug 19 andV the spring 24 in its lowermost position asv shown in Fig. 1. The upper yend of the rod 17 constitutes a movable contact, and'in line with the rod is a fixed contact 25 which is mounted in the lamp' socket but insulated therefrom and adapted to be engaged by the central pole of the lamp bulb. The weight of the rod and its connected parts causes the rod to normally assume the position shown in F ig. 1. The upper end of the rod is then spaced from the fixed contact and the lamp circuit, presently to bedescribed, is broken. .The sleeve 20 is of a proper size and shape and is so located on the standard as to provide a convenient handle to be grasped for lifting and carrying the lamp. l/Vhen the lifting force is iirst exerted upon the sleeve it is moved upwardly and carries the plug 19 with it. The plug 19 through the means of the spring 24 and collar 23 raises the rod 17 into contact with the fixed lamp contact 25. An electrical circuit from the battery to the lamp is thus closed.. The current flows through the battery contact 13, the fixed contact 11, wire 15, rod 17, fixed contact 25, the lamp 4, the lamp plug and socket, the standard and base of the lamp, (both of which are formed of conducting material) and through the battery contact 14. The weight of the lamp will hold the circuit closed while it is being held or carried by means of the sleeve. When the lamp is placed upon a support and the sleeve is released, the sleeve and the contact rod will gravitate to their lower positions and automatically open the circuit. The slot 22 in the standard, through which the screw 21 extends, is formed with a lateral branch 2 6 at its upper end and when permanent illum1nation is desired the sleeve 2O is moved up to .the limit of its movement upon the standard sleeve will not move upward suliiciently tov bring the screw in line with the branch slot 26. accidentally locked up in circuit closing position. In order to lock the sleeve it is pushed upwardly upon the standard a little further against the spring resistance until the screw registers with the branch slot.

The lamp circuit is also adapted to be closed automatically by merely inverting the klamp as shown in F ig. 2. The contact rod 17 and the sleeve 20, then, both gravitate to circuit closing position. This feature is an advantage when it is desired to direct `the light rays upon the floor as when searchlng for lost articles. The sleeve 20 preferably possesses considerable weight so that it will quickly slide upon the standard whenV the lamp is inverted and thereby accelerate the This ensures that the sleeve will not be closing of the circuit and will also quickly move to normal position when the lamp is placed upon a support.

The lamp is preferably made in the convenient form of a Candlestick with a slender standard and a wide flat base. The battery and the contact rod with its connected parts are all adapted to be inserted or removed through the under side of the base. To give access to the base it is merely necessary to slightly rotate the retaining plate 6 by means of short studs 27 to disengage the locking studs 7 from the key slots 9. The plate may then be lifted from the base. tubular standard opens at its lower end directly into the hollow base and the'contact rod with the plugs thereon may be easily inserted or removed therethrough. The vcontact rod and plugs may be released from the standard by merely withdrawing the screw 21 from the plug 19.
