Application July 18, 1933, Serial No. 680,903

This invention relates to new and useful improvements in means for locating the manual control of the operating switch on, especially, upright electric fixtures, such as are used in what are commonly known as floor and table lamps;

and among the varied objects of my improvements the most essentially are, to provide a manual control for the operating switch in the most easily accessible part of said fixture, and to afiord a manual control of the operating switch, which by its design, construction and location, will serve as an added decorative adornment of this kind of lamps.

In the drawings are shown two embodiments, which will illustrate the application of this invention on the two main types of decorative fioor or table lamps, which types differ in principle thereby that in case of the first type, the light emitting bulb is arranged, so as to extend upwardly from any suitable parts of the lamp fixture, and below those other fixture parts, which carry the lamp shade, whereas in the second type of the decorative floor lamps or table lamps, the light emitting bulb is downwardly directed and suspended directly from the lampshade carrier.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a partly sectioned elevation of a lamp arrangement of the first said type.

Figure 2 is a partly sectioned elevation of a lamp arrangement of the second type.

Figures 3 and 4 are top views on the different parts of the construction at the switch-carrying upper end of the lamp shown in Figure 1.

Figures 5, 6 and 7 are a top view of, and two crosswise vertical sections, respectively, through the switch-carrying, and shade-holding parts in a lamp of the second type, according to the Figure 2.

Referring more particularly to the drawings in the shown construction of the first embodiment (Figuresl, 3 and 4), a bottom-nipple 11 is provided at its lower part, with an outer male thread, to screw it on to any suitable lamp base, standard or pedestal; the upper part of the said nipple having an inner female thread, into which is screwed any standard kind of electric bulb socket 12. The middle zone 01 the said nipple has two diametrically arranged holes, from the outer ends of which the two tubular arms 14, 15 commence, said tubular arms are bent upwardly so as to form together a loop, and at the uppermost wider part of this loop the two arms 14., 15 hold between them the housing 16 for the electric switch 1'7.

This switch will be preferably of the two pole rotating type, and the upwardly elongated central part 18 of the switch body is provided with a screw-thread, on which may be screwed :1. mt hexagonal lock-nut, 19. The shade-carrier consists of a ring 20, with radially extending arms 21, and is placed on the lid of the switch-housl5 ing 16, and fixed thereto by the lock-nut 19. The rotatable switch-shaft 22 passes loosely through the switch-body elongation 18; and the threaded upper end 22 of the switch-shaft carries the switch knob or handle 23.

The wiring in this embodiment of the floor lamp or'table lamp is as follows: The two-eonductor cable 24 enters from below into the nipple 11; the one insulated conductor 25, goes directly to the one terminal of the bulb socket 12, 25 while the other insulated conductor 26, turns from the nipple 11 into the one tubular arm 14 and at the upper end of this arm the conductor 26 enters into the switch-housing 16 contacting with the one switch-terminal. From the other 3 switch-terminal starts the conductor 2'1, which goes through the other tubular arm 15 back into the nipple 11 and further to the cable 24. Where safety requirements demand double pole switches the tubular arms 14 and 15 may be 5 designed to hold :both conductors 25 and 26 as a double conductor in each arm.

The second embodiment of the invention. as shown in the Figures 2, 5, 6 and 7, contains likewise a lower threaded nipple 28, to be screwed on to any suitable lamp base, standard or pedestal. in which nipple the lower ends of the tubular arms 29, 30 are fixed; said arms are bent to form a frame of the so called lyre-shape. The upper ends of this frame or yoke hold a slightly offset cylindrical box 31, 32, with an inner insulating lining, and the lower part 31 of this box serves, by means of a suitable inner metallic outfit, as a bulb-socket, whereas the upper part 32 of this box serves as a switch- 5 housing. The upper lid of the switch-housing is provided with a perforated central plug 33, having a screwthreaded upper end, adapted to receive the flat hexagonal lock-nut 34. The shade-carrier, consisting of a ring 35 with radino ally extending arms 36, is placed on the "lid of the switch-housing 32, and secured firmly at this position by the lock-nut 34. In this embodiment likewise a two-pole switch of the rotating type has been provided, as the shaft 37 of the rotor-part of this switch passes loosely through the lid 01' the switch-housing and through the plug 33; and the upper screwthreaded end of this shaft carries the switch grip or handle 38.

The stationary body-part or the switch is a block 39 of insulating material, inserted into the switch-housing 32 and provided with a number of suitable recesses to accommodate the metallic current conducting parts of the switch. In one 01 these recesses is fixed the one switch-terminal 40, which is in metallic connection with the one terminal of the bulb-socket, namely with the threaded shell 41 of this socket. Diametrically opposite to the first recess of the switchbody is another vertical recess 42, the upper end 01' which 15 broadened by a bent channel 43,

centre of the top part of the switch-body 39 is a cavity, containing the rotor part 44 01' the switch and the two cooperating resilient contact tongues the one of these contacting tongues 55 terminating in the aforesaid channel 43, the other of the contact tongues 55 being connected with a conductor 56, which leads through another ve ical recess 57 (see Fig.

other terminal 58 of the bulb socket.

The rest of the electric wiring of this type of lamps consists simply in the two-core cable 59, which branches at the lower nipple 28; the one branch 60 going through the one tubular arm 29 to the one switch-terminal 40, and the other cable-branch 61 going through the other tubular arm 30 and through the recess 42 and channel 48 to the corresponding contact-tongue or spring 55.

The operation, and the working of the switch is like in ordinary lighting fixtures, so that it will not be necessary to trace herein in detail the flow of the current.

It is important appended claim, spirit of the invention, and I do not therefore wish to limit myself to the construction and arrangement shown and described herein.

Having thus described my invention, what I claim as new and desire to secure by letters Patent 01 the United States, is:

In-alighting fixture adapter of the character described, a standard base nipple, a lamp socket attached to the upwardly extending end of said nipple, said nipple carrying two outward and upwardly extending tubular supports terminating in a switch housing, an insulated electric the topmost end of said shaft, whereby said switch may be operated and whereby the lighting fixture adapter may be suitable for any type of shade.
