United dtates Patent TABLE LAMPS Benno Koch, Geneva, Switzerland Application November 4, 1954, Serial No. 466,747
Claims priority, application Switzerland September 4, 1954 2 Claims, (Cl. 240-4659) The invention relates generally to a table lamp, which possesses an outer luminous screen, is rotary upon a base about a vertical axis and comprises various fitted colored sheet members; within the said screen a fixed screen is accommodated having a light outlet aperture, and a bulb within the free space of the fixed screen whereas on the base there is disposed a switch, by means of which the lamp can be switched on and off.
It is one of the primary objects of the invention to provide means affording avery efficient and compact lamp construction of the aforesaid type which'is easily operated andwhose few essential parts may be readily assembled and disassembled for the purpose of changing light elfects.
These and other objects of the invention will become I in Fig. 1.
The table lamp possesses a two-part hollow base portion 1, which is closed by means of a cover plate 2. The base portion is provided at the centre with a circular aperture 3, in which there is fitted a fixed screen 4, which possesses an opening 5 for the passage of light from an electric bulb 6 located within the confines of said screen. The electric bulb is carried by a sockets held in the boss 7 of the fixed screen 4, the mounting or socket 8 receiving electric current through leads 9 and by way of a switch 10, the supply of current being capable of being controlled by the push-button 11. The base 1 also possesses an annular recess 12, in which the holding ring 13, which is rotatable about a vertical axis, is held against the bottom of the fixed screen 4. In the upper side of the ring there is provided agroove 14, in which there are fitted sheet members 15, of which one may possess a light or white colour, another a blue colour and the Third a green colour or any other desired colour combination. These sheet members are curved and have a partly cylindrical form and extend each over an angle of approxi-' mately 120 (Fig. 2). Between the vertical edges of each two sheet members there is arranged a grooved retaining member terminating in a screw element 16, which is held in the rotatable ring 13 by means of screw threads 17 and possesses at the upper end a nut 18. A top portion 19 engages over the upper open end of the screen 4, while the grooved retaining or supporting members 16 of the outer screen, the ring 13, the screen members 15 and the top element 19 form a unit, which is held firmly together and is capable of rotation in the recess 12 of the base 1. In the top element 19 there are provided air apertures 20, which by means of va disc 21 secured to the top in the space between the top and the electric bulb are ice screened in such a manner that rays of light are unable to pass out upwardly. In the base and in the bottom of the fixed screen there are provided air inlet apertures 22, through which air entering through slots 23 in the edge of the base reaches the interior of the fixed screen, flows abontthe electric bulb, cooling the same, and is able again to pass out at the top element 19 through the openings 20. In the base there is provided at least one spring pin 24, which cooperates with notches 25 on the underface of the ring 13 and enables the coloured sheet members to be held in their adjustment in front of the light outlet aperture 5 of the fixed screen according to the respective dilferent colour desired.
Adjustment of the rotary screen 15 is etfected by gripping it by the hand of an operator on the outside and rotating said screen.
Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. A table lamp having a base; comprising a fixed upright screen provided with a bottom and a lateral opening, a socket for a bulb centrally arranged with respect to and spaced from said fixed screen, whereby light rays from said bulb may be emitted through said opening, and a screen unit arranged for rotation exteriorly of and concentrically to said fixed screen and provided with a rotatable base n'ng seated in a recess of said base and retained therein by said bottom of said fixed screen which overlies a portion of said rotatable base ring, interengageable means, respectively, provided on contiguous faces of said base ring and said base to thereby facilitateadjustment of said screen unit relative to said opening, said rotatable screen unit including a plurality of colored and curved screen sections, a plurality of spaced retaining members located between adjacent screen sections to engage and to maintain same in position, each retaining member being fixed at one end thereof to said base ring, a top element overlying and spaced from said fixed screen and attached to the other end of said retaining members, respectively, and air inlet and air outlet means provided in said base and in said top element, respectively, and in communication with the space between said socket and said fixed screen, said top element being provided with a baffle disc of sufiicient diameter and located below said air outlet means of said top element to permit passage of air past theperiphery of. said disc and to avoid loss of light emanating from said bulb when inserted in said socket.
2. A table lamp according to claim 1, said interengageable means including notches on the underface of said base ring and a spring-supported pin set in said base and urged against the underface of said base ring, said notches being arranged adjacent said retaining members, respectively.
