HOLDING DEVICE FOR LAMP SHADE FRAMES Filed July- 3, 195.4
INVENTOR l//szfA///l/ff ,M4/7644 Patented Oct. 27, V1936 UNITED STATES PATENT ortiesr HOLDING DEVICE FOR LAMP SHADE FRAMES 2 Claims.
This invention relates to lampshade frames and more particularly to shade frames for electric lamps. An object of the invention is to produce an article of this character which, While simple and inexpensive to manufacture and assemble, is safer and more efficient in use than articles of the kind with which I am familiar.
A feature of the invention resides in the provision of an apertured member which serves as a medium by which the lampshade frame is held in place.
Another feature resides in the provision of means to insulate electrically the frame of the lampshade holder from the electric light socket with which it is used.
A further feature resides in the use of a member of di-electric material which not only serves as an electrical insulator but also serves as a medium through which the lampshade frame is held in place.
Further features and advantages will become apparent from the following detailed description and claims when taken in connection with the accompanying drawing in Which:-
Figure 1 is an elevation of my improved lampshade holder showing the same in use, the shade being indicated by dotted lines;
Figure 2 is a vertical section also showing the lampshade frame in use;
Figure 3 is a top plan view showing the lampshade holder; and
Figure 4 is a similar View of a modification.
Referring to Figure 3 of the drawing, my improved lampshade holder comprises three elementsa shade-supporting element 2, an apertured member 4 of di-electric material and connecting means 6 between the first two mentioned elements, the latter being formed into loops I under member 4. The element 2 may be made of wire or other suitable materialA and may be of any desired shape. The connecting means 6 may be a single wire but in the preferred form I use two Wires which are connected at 1 to the element 2 by soldering or otherwise.
The member 4 is preferably made of material which is a non-conductor of electricity and such member may be of fibre, bakelite, gutta-percha or similar substance.
While this member is shown in the form of a ring, it may, of course, be of any suitable shape but for the purpose for which it is to be used the aperture is of such size as to permit the passage therethrough of the threaded end of an electric light bulb. In the form of the invention shown (Cl. 24U-13S) in Figure 3, the member 4 is also apertured at 8 and the wires 6 passed through these apertures.
In the form of invention shown in Figure 4 notches 9 are formed in the member 4 and the Wires 6 rest in the bottom thereof.
Below the member 4 each of the wires 6 is formed into a loop Ill between which the electric light bulb is passed when the shade holder is applied to an electric light socket as shown most clearly in Figures 1 and 2.
In these figures an ordinary electric light socket is shown such as is ordinarily found in electric lamp stands. This socket comprises an outer casing I2 which is usually of metal and contains an inner threaded portion I4 for receiving the threaded end I5 of an electric light bulb I6. As previously stated, the aperture in the member 4 is of such size as to permit the threaded 'end I5 of the electric light bulb to be passed through it but is not sufficiently large to permit the member 4 to slip over the end of the socket. Therefore, when the frame is applied to the socket and the electric light bulb screwed home the member 4 rests on the bulb, thereby holding the shade frame in place.
The member 4 is wide enough so that the wires 6 at the point where they pass through the apertures 8 or into the notches 9 do not come in contact with the outer casing I2 of the socket. All of the metal parts of the frame and the holder are therefore electrically insulated from the socket so that there is no danger of getting a shock when the holder is adjusted to position. The loops I0 are not necessary to the complete functioning of the holder of the present invention but they do act to give rigidity to the frame, since in actual use they bear against the surface of the bulb. It is customary, however, to use the holder in a somewhat different manner when the socket and bulb are in an upright position. Under these conditions the loops are merely sprung over the end of the bulb.
It Will thus be seen that my improved lampshade holder is adapted to be used with the bulb upright` or pendant, the latter being the preferred manner of use. When so used, the member 4 forms the medium whereby the frame is secured to the socket and further serves to electrically insulate the framework of the holder from the socket, thereby making it a safe device to use.
The manner of assembling is very simple. The two Wires 6 are given the proper loop form and the ends passed through the apertures 8 of the member 4 or are seated in the notches 9 when 55 the construction shown in Figure 4 is used. They are then bent at the proper angle and secured to the frame element 2.
What I claim is:
l. A lamp shade frame comprising a wire ring, two wires attached at dametrically opposite points to said ring, each wire having a central loop, the two loops constituting a clamp for supporting the frame on the lamp in one position of the frame, a member of dielectric material through which said wires pass, said member being centrally apertured for the passage of the screw end of an electric bulb, the size of the aperture being such that the threads of the bulb may pass therethrough but not large enough to permit the member to pass over the end of an electric light socket, said member serving as the sole medium through which an electric light bulb may secure the lampshade frame to an electric light socket.
2. A lamp shade frame comprising a Wire ring, two wires attached at diametrically opposite points to said ring, each Wire having a central loop, the two loops constituting a clamp for supporting the frame on the lamp in one position of the frame, a ring-like member of dielectric material, diametrically arranged openings in said member through which said Wires pass beyond the loop portions thereof, the ring opening being large enough to permit the passage of the screw end of an electric bulb therethrough but not large enough to permit the member to pass over the end of an electric light socket, said member serving as the sole medium through Which an electric light bulb may secure the lampshade frame to an electric light socket.
