ELECTRIC BOUDO'IR LAMP.

Application filed June 23, 1923. Serial No. 648,266.

To all whom it may concern:

Be it known that I, CHARLES WAoHTnL, a citizen of the United States, residing at New Hyde Park, county of Nassau, and State of New York, have invented certain new and useful Improvements in Electric Boudoir Lamps, of which the following is a specification.

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 placed on a table or other support, and will be complete or closed when the lamp is lifted and carried about in the hand.

Another object of the invention is to provide means whereby the lamp circuit may be permanently closed so that it will not be affected by placing the lamp on a table or sup port, or lifted therefrom.

The lamp is illustrated in the drawings 1n the form of a candle stick, but of course it will be understood that it may be made up in any suitable'form.

In the drawings, Fig. 1 is a side elevation of the lamp;

Fig. 2 a vertical central sectional view thereof resting on a support and the lamp circuit interrupted;

Fig. 3 a vertical sectional View of the base of the lamp showing it raised from its support with the lamp circuit complete or closed;

Fig. 1 a diagrammatic view illustrating how the lighting circuit is opened by placing the lamp onv a support;

Fig. 5 a bottom plan View of the lamp with the bottom plate in open position;

Fig. 6 a bottom plan view of the lamp with the bottom plate in closed position;

Fig. 7 a detail vertical sectional view of the switch operating plunger;

Fig. 8 a detail bottom plan view of a portion of the base showing the switch operating plunger moved into inoperative posi-, tion;

Fig. 9 a detail vertical sectional View of a portion of the base showing the switch operating plunger in the position shown in Fig. 8; and I Fig. 10 a diagrammatic view illustrating larged chamber adapted to receive a cuplike receptacle 4: of insulating material. Into the upper end of this receptacle is screwed a metal lamp socket 5 designed to receive the threaded end of a lam bulb 6. Threaded through the bottom of t e cup. 1 is a terminal 7 to the lower end of which, within the post 8, is connected one wire 8 of the lamp circuit. The terminal'7 is adapted to engage the central contact of the lamp base. The other terminal of the lamp is connected to the threaded outer shell of the lamp base which forms an electrical connection with the threaded socket 5 in the usual manner. Connected to the socket 5 is the other wire 9 of the lamp circuit, said wire being carried downwardly through the insulating cup 1 and thence downwardly through the tubular post 3. The circuit wire 8 is carried into the lamp base and is rigidly connected to a contact plate 10; and the circuit wire 9 is carried into the lamp base and connected to the contact plate 11 mounted on the inner side of the circular side wall of the base.

The lower side of the base is closed by a bottom plate 12, which preferably is of sheet metal and is hinged to the lower edge of the base at 13. Thehinge 13 is in direct engagement with a contact plate 14 secured to the inner surface of the side wall of the base, said contact plate being adapted to be engaged by one of the poles at of a dry battery 15, the dry battery fitting within the hollow base as shown in Fig. 5. The other pole b of the battery is adapted to engage the contact plate 11. The short rigid legs 2 are connected to the bottom plate 12 and the lower edge of the annular wall of the bottom is cut out slightly to receive the bottom plate, so that the lower surface of said ]plate is flush with the lower edge of the ase.

' away from the bottom plate 12.

The contact plate 10 carries 9. depending vertical contact member 16' and a depending tubular post 17 said post being open at its lower end. Sliding vertically in said tubular post is a stud 18 which carries at' pin 22, which normally engages the bottom plate 12 and makes electrical contact therewith. The lamp circuit is normally closed through the battery poles and contacts 11 and 14 thence through the hinge 13, bottom plate 12 and contact pin 22, the plate 19 and its contact members constituting a normal closed switch.

A switch operating plunger 23 is carried by the bottom. plate 12 directly below the switch plate 19. This switch operating plunger is mounted in a lever 21 pivoted to the under side of the bottom plate 12. This lever is formed with a vertical opening in the tubular part 25, the upper end of which projects through a slot 26 formed in the bottom plate. The switch operating plunger is provided with an upper tip 27 of insulating material which is adapted to engage the switch plate 19 and force it up wardly to thereby lift the contact pin 22 The plunger slides freely in the tube 25 and is provided with a collar 28 at its upper end which is adapted to engage the upper end of the tubular part 25 and serve as a stop to limit the downward movement of the plunger. The lower end of the plunger is provided with a downwardly adjustable contact head 29 which is adapted to engage the table or support on which the lamp rests. The contact head 29 is of sutlicient diameter to engage the lower end of the tubular portion 25 and thereby limit the upward movement of the plunger. The plunger is mounted on the lever 24 so that it may be swung laterally out of the path of the switch plate 19, as shown in Figs. 8 and 9 of the drawings. In this position of the plunger it is inoperative to open the lamp circuit and the said circuit will remain closed. \Vith the lever 24 in position to bring the switch operating plunger below the switch plate, as illustrated in Figs. 2, 3 and 6, the plunger will act to force the switch plate upwardly and thereby open the lamp circuit. The plunger slides freely through the lever 24 and the tubular housing so that when the lamp is placed on a support there will be a relative vertical movement between the lamp body and the plunger and this relative movement will bring about the opening of the lamp circuit. The plunger is so adjusted as to length that when the lamp is raised from its support the lower end of the plunger will be below the lower ends of the supporting legs 2. This position of the plunger is illustrated in Fig. 3. When the lamp is placed on a support the weight of the lamp is suilicient to cause the plunger to move upwardly into the base and thereby force upwardly the switch plate 19. This moves the contact plate 22 away from the closure plate 12 and thereby opens the lamp circuit. lVhen the lamp is lifted from its support the spring 20 forces the switch plate 19 downwardly to bring the contact pin 22 into engagement with the plate 12. This closes the lamp circuit. The plunger will be forced downwardly by the spring if it does not drop by gravity. By swinging the lever 24 on its pivot, as shown in Figs. 8 and 9 the switch operating plunger is carried laterally out of operative relation to the switch plate. The end of the switch plate is turned upwardly at 19" to form an inclined cam surface, directly over the end of the plunger, when it is in its nonoperating position. This prevents the end of the plunger engaging and locking on the edge of the switch plate should the plunger stick in its upper non-operating position.

It is manifest that the dry battery may be readily removed from the lamp base and that it will be locked within the lamp base by the closure plate 12. The closure plate is slotted at one edge to receive a turn button 30, said button forming a simple lock to hold the plate 12 in its closed position.

From the foregoing it is clear that I provide a very simple portable self contained electric lamp adapted for household use. When the switch operating plunger is properly adjusted the lamp may be lighted by merely lifting it from its support. The lamp will be extinguished by placing it back on its support. \Vhenever it is desired to maintain the light it is only necessary to move the lever 24 and thereby shift the switch operating plunger into its non-operating position.
