ELECTRIC FIXTURE.
Specification of Letters Patent.
Patented Oct. 11, 1921.
Application filed November 11, 1920. Serial No. 428,400.
To all whom it may concern Be it known that I, FRANK L. BUTLER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a newand useful Improvement in Electric Fixtures, of which the following is a full, clear, and exact description.
My invention relates to improvements in electric fixtures, and it consists in the combinations, constructions, and arrangements herein described and claimed.
an object of my invention is to provide an improvement over the device shown in my prior application for Letters Patent on an electric fixture Serial No. 414,212, filed October 2, 1920, in which I disclosed a fixture having a hollow stem incased for a portion of its length, formed with a lateral aperture through its wall, and provided with a plug for guiding the electrical conducting wires from the stem through the lateral aperture, said improvement consisting in the provision of a stem having more efficient and practical means for guiding the electrical conducting wires from the stem through the aperture in the wall thereof and being adapted for direct connection with an element in a lighting fixture, such as a mounting for a globe, shade, or the like.
A further object of my invention is to provide a device of the type described having a novel means for guiding the electrical conducting wires from the stem through an opening in the wall thereof, such means being removable and possessing inherent qualities operating to maintain the same in adjusted position.
A further object of my invention is to provide a device of the type described'in which the number of elements is reduced to a minimum, wherefore the device can be produced commercially at a comparatively low cost.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a central section through the device,
Fig. 2 is a similar view of a fragmentary In the form of the device shown in Fig. 1, the
stem 4: is formed of any suitable insulating material, such as an indurated fiber. A casing 6 is mounted on the stem 1, encircling the lower portion thereof and is provided with an inwardly extending flange 7 at its lower end curved to conform with the contour of the end wall of the stem 4% and arranged to lie snugly thereagainst to protect the same. The bore of the stem 4 is threaded interiorly at 8 for engagement with a close nipple 9 that projects beyond the end thereof. An elbow 10 fitting on the projecting end of the nipple 9 maintains the casing 6 in position on the stem 4 and is adapted for direct connection with the mounting of a lighting fixture, (not shown) such as the socket for a shade, globe, or the like.
The stem 4 has an obliquely extending opening 11 through its wall at a spaced distance from the upper end thereof. Electrical conducting wires 12 are passed into the bore of the stem l through its lower end and must then be projected through the side opening 11 and extended for connection with the conducting means (not shown) that are in the wall 3. Considerable dii'liculty in fishing the wires 12 from the bore of the stem has been experienced prior to my invention. To provide means for guiding the wires 12 through the opening 11 when portions thereof projecting beyond the end of the stem & are moved toward the same, is one of the objects of this invention. To this end a groove 13 adapted to receive the laterally bent end 1 1 of a guiding spring clip 15 is provided in the inner wall of the stem 4. The guiding clip 15 is formed as best seen in Fig. 4 of the drawings and c0mprises diverging arms 16 and 17. The arm 16 is arranged to extend along the inner wall of the casing l diametrically opposlts the opening 11 and terminates in the laterally turned end 141- that is received within the groove 18. The curved arm 17 is folded backwardly at 18 and the end portion thereof is then bent at 19 to extend along the inner wall of the casing 4', thereby provid ing a socket 20 adapted to engage with the angular edge portion 21 of the upper wall of the opening 11. Theguiding clip 15 is preferably formed of material having spring qualities operating to maintain the clip in the position illustrated, since the arm 17 is forced slightly toward the arm 16 when the clip is placed Within the bore of the casing 4. A canopy 22 is mounted on the casing 6 and secured in adjusted position therealong by means of a set screw 23.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The electric conducting wires 12 may be instantly passed through the stem 4: and therefrom through the lateral opening 11 without any appreciable effort, since the guiding clip 15 will guide the inserted ends of the wires from the opening 11 without hindering the progress of the same. The clip 15 may be quickly placed in operative position when the fixture is being installed.
Referring now to Figs. 2 and 3, I show modified forms of the same device. Like parts in the several figures have been designated'by the same reference characters and I shall accordingly confine my description of the modified form of the device to parts thereof that differ from the parts in the preferred form of the device. Referring now particularly to Fig. 2, I show the stem 4 and the casing 6 horizontally disposed as when the device is applied to a fixed support projecting from a side wall. A bracket 25 has an interiorly threaded portion 26 engaging with the projecting end of the nipple 9 and held in adjusted position therealong by means of a set screw 27. The electrical conducting wires 12 pass into the stem 4 from a lamp socket, or the like (not shown) that is mounted in and supported by the bracket 25. Referring now to Fig. 3 of the drawings, I show a metallic stem 30 threaded at its upper end at 31 for connection with the coupling 1 or with an insulating joint (not shown) if the requirements of the service for which intended are such that the fixture must be insulated. The stem 30 is formed with anobliquely extending lateral opening 32 similar to the opening 11 and is incased for a portion of its length by a casing 33. It will be under.- stood that the finish of the casing 38 will correspond with that of the canopy 22 and that the stem 30 will be entirely concealed from View when the device is assembled and installed. The guiding clip 34 has an arm 35 extended to the upper end of the stem 30 and then bent outwardly at 36 to overlie the end wall thereof. A curved diverging arm 37 extends obliquely across the bore of the stem 30 and is folded backwardly at 38 and then upwardly at 39 to engage with the inner wall of the casing 30 and to provide a socket 4:0 adapted to receive the angular edge portion 41 of the wall of the opening 82. The guiding clip 34 has spring qualities and performs the same function in the modified form of the device as the guiding clip 15 in the preferred form of the device. The electrical conducting wires 12 are passed through the opening 32.
I claim:
1.
