Application July 31, 1950, Serial No. 176,859

2 Claims. (Cl. 240-10.6)

The present invention relates to improvements in n 1ght lamps, and more particularly to a night lamp provided with a luminous means for indicating the posltion of the lamp at night time.

An object of the present inventlon is to provide an improved electric contact actuating means whereby the lamp bulb may be illuminated.

The invention also comprises novel details of construction and novel combinations and arrangements of parts which will more fully appear in the course of the following description.

Various other objects and advantages Wlll be apparent from the detailed description to follow, wherein parts are at times identified by specific names for convenience, but such nomenclature is intended to be as generic in its application to analogous parts as the prior art will permit.

The best form in which I have contemplated applying my invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical sectional view of the present 1nvention with the electrical circuit closed;

Figure 2 is a horizontal transverse sectional view taken substantially along the plane of line 2-2 of Figure 1; and

Figure 3 is a vertical transverse sectional view taken substantially along the plane of line 33 of Figure 1.

Referring more particularly to the drawings, wherein like numerals designate like parts throughout, numeral designates generally the base mounting means, numeral 12 designates generally the bulb socket means, numeral 14 designates generally the dry cell tubular housing and cam actuating means, and numeral 16 designates generally the luminous means and bulb arrangement of the present invention.

The base supporting means 10 includes a hollow housing having a preselected ornamental design for its upstanding portion 18, and a flat base wall 20 upon which the invention is rested, the base means 10 being hollow and provided with an internally threaded and apertured upper portion 22. The base wall 20 is provided with a stop projection 24, for a purpose to be hereinafter described.

The dry cell 26 is mounted within a tubular housing 28 which is fixedly secured to the base wall 20 at a central portion thereof and is provided with transversely extending apertures 30 in axial alignment with each other and offset from the center line of the tubular housing.

Slidably mounted on the base wall 20 and engaged with the apertures 30 of the tubular housing 28 is a cam actuating slide element 32. The cam actuating element 32 is provided with an elongated wire 34 extending therefrom and provided with a button 36 at its outer end, whereby reciprocation of the cam actuating element 32 on the exterior of the base mounting means 10 is made possible. The cam actuating element 32 is provided with a surface 38 which may be inclined in either direction whereby reciprocation of the cam actuating element may be employed for vertical reciprocation of the dry cell 26.

An electrical conducting element 40 is positioned with its upper end embedded inthe socket-receiving portion 22 and with its lower end connected to a contact button 42 which is in sliding engagement with the inclined surface 38 of the cam actuating element 32.

An externally threaded tubular sleeve 44 is positioned Within the socket-receiving portion 22 of the base means 10. The lower end of the sleeve 44 is provided with a contact element 46 which is adapted to be connected to 2,695,355 Patented Mir-2.3, 1954 the contact element .48 atthe upper. end f he electric l conducting element 4.0 when the sleevelsl is fully threade into the aperture 22. .A reflector 5.0 is mounte Within the sleeve 44 bymeans of its periphery 52 engaged in the counterbore 54.0f the sleeve .44. The reflector 50 is. provided .with a socket. portion 5.6 in which a lamp bulb 58 may be threadably positioned, and an electrical conductor 60 connects the socket 56 with the contact button 46.

The luminous lamp structure 16 includes a transparent bulb portion 62, which may be formed of glass or plastic that is translucent, which has its lower end fixedly mounted within a recessed portion of the sleeve 44. The upper end of the bulb portion 62 is provided with a blister-like semispherical extension 64 in which is positioned a crimped reflector 66 whereby the light rays from the lamp bulb 58 may be diffused and deflected.

Artificial flowers 68 are mounted with the bases of their stems fixed in the sleeve 44 and are upwardly standing within the bulb portion 62. The artificial flowers 68 may be formed from glass or metal, and, if desired, means other than flowers may be employed. The artificial flowers 68 are covered with a luminous material which glows in the darkness.

From the foregoing description, taken in conjunction with the drawings, it is believed that the operation of the present invention will be readily obvious to one skilled in the art. By moving the button 36 outwardly, the cam actuating element 32 and button 42 will move the dry cell 26 upwardly, providing an electrical contact with the button on the bottom of the lamp bulb 58 and completing the electrical circuit therefor. It should be noted that by positioning the cam actuating element in an off-center relationship with the dry cell that every time the element 32 is reciprocated, the dry cell will be partially rotated, maintaining the dry cell free for vertical reciprocation and preventing corrosion from freezing the positioning of the dry cell.

It is believed that from the foregoing a device has been provided which will accomplish all of the objects hereinabove set forth.

Having described the invention, new is:

1. In a lamp, the combination of a housing having a flat bottom and provided at the top thereof with a lamp socket, a bulb positioned in said socket, a vertically disposed tubular battery holder provided in said housing under the socket in concentric alignment therewith, a bat tery rotatable and slidable vertically in said holder and including a centrally disposed upper terminal electrically engageable with said bulb when the battery is slid upwardly, a switch block slidable horizontally on said bottom under the battery and having an inclined upper surface, means for sliding said switch block, a contact member flexibly and electrically connected to said socket and positioned between said switch block and said battery radially of the axis of the holder whereby sliding of the switch block efiects rotating and sliding movement of the battery in the holder.

2. A portable night lamp comprising a housing having a base and provided at the top thereof with a lamp socket, a bulb in said socket, a vertically disposed tubular battery holder in said housing secured at its lower end to said base under the socket and in concentric alignment therewith, a battery in said holder including a centrally disposed upper terminal and a flat lower face constituting its other terminal, the lower end of said holder being notched at circumferentially spaced points therewhat is claimed as along, an elongated switch block having an inclined (References on following page) References Cited in the file of this patent Number UNITED STATES PATENTS Name Date Hitzelberger Nov. 21, 1916 5 Recker May 8, 1917 Ludescher Dec. 4, 1917 Dodds Aug. 13, 1918 Liedtke May 12, 1925 Muramatsu Mar. 30, 1937 10 Number Number Name Date Wiley Ian. 25, 1938 Graubner Mar. 28, 1939 Sullam July 3, 1945 FOREIGN PATENTS Country Date Germany June 1. 1922
