UNITED STATES PATENT OFFICE.
FRANK LOWELL BUTLER, or CHICAGO, ILLINOIS.
ELECTRIC FIXTURE.
To all whom it may concern:
Be it known that I, FRANK LownLL BUTLER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Electric F ixtures, of which the following is a full, clear,
"tive thereto by means of a nut screwed on the lower end of a rod that extends entirely through the tubular member and has its upper end engaging with a cap secured 'to the insulating member, said improvement consisting in the provision in an electric fixture of a novel form of stem.
A further object of my invention is to provide in a device of the type described, a stem that comprises the fewest number of parts consistent with effective operation in the service for which intended. V
A further object of my invention is to provide a device :of the type described that is simple in construction, ornamental in appearance, not likely to get out of order easily, and thoroughly practical commer Y r provide shoulders adapted to rest upon the ciall 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. I
My invention is illustrated inthe accompanying drawings, forming part of this'application, in which Figure 1 is a central vertical sectional view of the preferred form of the device.
Fig. 2 is asimilar View of a fragmentary portion ofa modified form of the device.
Fig. 3 is aperspective View of a portion of the device.
Fig. 4 is a view similar to Fig. 1 of a fragmentary portion of another modified form of the device.
. In carrying out my invention, I make use Specificationof Letters Patent.
Patented Sept. '20, 1921.
Application filed November 12, 1920. Serial No. 423,638.
of a fixed support, such as a gas pipe 1 that ordinarily projects from a wall 2 and place on the threaded end thereof a coupling 3. The coupling 3 is formed with a transverse partition 4:, as shown. The stem of the device, in its preferred form, consists of an upper insulating member 5 that is threaded exteriorly at 6 for engagement with the coupling 3. Theinsulating member is preferably tubular, as shown, for lightness and economy, but obviously may be 'solid and formed as desired. A tubular .member 7 is fitted on the insulating member 5 and incases the lower portion thereof. A sufiicient length of the insulating member remaining uncased to effectually insulate the tubular member 7 from the coupling 3.
The lower portion of the insulating member 5 is preferably unthreaded and the tubular member 7 is secured in fixed relation therewith by means of a pin 8 that is projected through registering openings 9 and 10 in the walls of the tubular member 7 and the insulating member 5, respectively. This method of securing the tubular member 7 to the insulating member 5 obviates the necessity of threading exteriorly the tubular member 7 andtherefore permits the use of a tubular member having a relatively thin wall.
The tubular member 7 is formed with an inwardly extending flange 11 at its lower end. A washer 12 placed within the tubular member 7 rests upon and is supported by the flange 11, which is turned upwardly slightly along its edge. A link 13 formed of material having spring qualities and havin its remote walls reduced at i l-14 to Washer 12 is placed in the position illustrated in Fig. 1. This is accomplished by moving the ends of the link 13 together and then inserting the link within the tubular member 7 at the upper end thereof, wherefore the spring quality of-the link will maintain the same in the position shown. It will be understood that a chain or the like (not shown) is connected to the link 13 to depend therefrom. A lighting fixture or the like will be supported by such a chain.
The tubular member 7 has an opening 16 in its side wall adjacent the upper end thereof. A curved guiding clip 17 that has in general an oblong shape is formed, as best seen in Fig. 3, and is arran ed to enter the opening 16 until the end thereof contacts with the opposite inner wall of the tubular member. A guiding clip 17 is formed with an extension 18 adapted to extend upwardly along the tubular member 7 exterior of the opening 16. The extension 18 has an opening 15 therethrough and consequently the guiding clip 17 is maintained in a fixed position relative the tubular member 7 in the preferred form of the device by the pin 8, which is projected through the opening 15 prior to its insertion through the registering openings 9 and 10.
Electrical conducting wires 19 are projected into the tubular member 7 through the open lower end thereof and are guided therefrom by the guiding clip 17 through the opening 16 into position suitable for operative connection with the wires (not shown) that are ordinarily installed in the wall 2. A canopy 20 is slidably disposed on the tubular member 7 and is secured in adjusted position therealong by means of a set screw 21.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood, and requires no detailed explanation. The device comprises relatively few parts and is therefore capable of being manufactured with economy in time, labor and material. At the same time, the device comprises all parts necessary for the efiective functioning thereof in ordinary service and in its assembled condition has the appearance of a more complicated and expensive electric fixture. Referring now to Fig. 2, I show a modified form of the device. Like reference numerals have been applied to like parts throughout need notbe insulated in the service for whichintended or for engagement with any suitable fittlng, (none being shown,) such as an ordinary insulating joint or the like.
The tubular member 7 is fitted'on the lower portion of the tubular metallic member 30 and is secured in fixed relation thereto by means of the pin 8 that is projected through registering openings 9 and 82 in the walls of 'the lower tubular member 7 and the upper tubular metallic member 30.
In the modified form of the device illustrated in Fig. 2, a guiding clip 33 is arranged within the bore of the tubular member 7 in the manner described and has an extension 34 arranged exterior of the opening 16, as shown, such extension being maintained in adjusted position relative the tubular member 7 in any suitable manner, as by being soldered to the wall thereof.
Referring now to Fig. 1, it will be noted that I may dispense with the washer 12 when the stress incident to the service for which the modified form of the device is intended will not be sufficient to overcome the resistance of a flange 40, which consequently need not be turned upwardly at its edge. A U-shaped link 41 having spring qualities has the end portions thereof inserted within the lower ends of the tubular member 7 and are provided with kerfs 42-42 in the remote walls thereof adapted to engage at diametrically opposed points the flange 40. On account of the spring qualities of the material composing the U-shaped link 41, the latter will be maintained in a fixed position relative the stem 7. The operation of each of the modified forms of the device as illustrated in Figs. 2 and 4, is identical with the operation of the preferred form of the device illustrated in Fig. 1 and consequently no detailed description of the operation of the modified forms is required.
I claim:
1.
