ELECTRIC FIXTURE.
Specification of Letters Patent.
Patented June 11, 1912.
Application filed May 4, 1911. Serial No. 624,989.
To all whom 'it may concern:
Beit known that we, J OHN L. PALMER and CHARLES N. XVIIEELER, citizens of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Electric Fixtures; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an improvement in an electric fixture and pertains more particularly to an arm or extension for a fixture body, or wall bracket.
An object of the invention is to provide means for closing the outer end of the hollow arm which carries the electric lamp or bulb, and to combine with said means a fixed or detachable extension or nipple for receiving the lamp socket.
Another object is to so arrange the closure for the end of the arm that both it and the extension or nipple which it carries can be inserted as a unit into the arm, involving but a single operation, the said closure being held in place by friction.
Another object is to furnish one of the walls of the arm with a hole or recess of sufiicient size through which to pass the extension or nipple of the closure and through which said extension or nipple can be readily inserted and withdrawn in assembling or disassembling the device.
In the accompanying drawing; Figure 1 is a longitudinal sectional elevation of a hollow arm showing a closure for its end and a lamp holding extension for said' closure. Fig. 2 is a similar view showing the closure withdrawn and in position to raise the extension or nipple from the opening in the wall of the arm. Fig. 3 is a similar View except that a side elevation of the closure and nipple is shown, said closure having been raised into the upper part of the arm ready for withdrawal therefrom. Fig.
4 shows the closure and its extension or nipple in perspective. Fig. 5 is a longitudinal section of the arm as shown in the first three figures in which the closure and its extension or nipple are shown as separate parts, and Fig. 6 is a plan of the closure.
It is the desire to provide a very simple arrangement for assembling and disassembling the parts of an arm carrying an electric lamp, preferably using friction as the method of holding the closure in the end of the arm and in which the closure shall carry an extension or nipple, the latter being either made as an integral part of the closure or as a part separate therefrom, as desired, there being no clamping means employed by which to hold the closure and arm together, the closure and nipple being movable together or as a whole relative to said arm.
A indicates a hollow arm of a fixture or of a wall bracket, neither of which are shown, said arm in the latter instance being secured to the spider of orow foot (not shown) attached to the wall in the usual manner. The arm serves as a conduit for the conducting wires shown at a in Fig. 3, its outer end being closed by a capplate B the inner side of which is provided with an integral extension C which, preferably, is made in some such form as shown in Fig. 4 whereby its parts will engage the inner wall surfaces of the arm and preferably slightly tapered so as to have a snug driv ing fit into said arm, said cap-plate or portion B acting as a stop by engaging the end of the arm and also as a grasping piece. However, it is not our intention to confine ourselves necessarily to the exact form of this extension since if desired the side portions C, Fig. 4, may be eliminated or such other changes may be made as will lie within the meaning of the invention, it being desired only that suflicie'nt frictional surface be provided to hold the closure or cap-plate firmly in position and such changes as may be desired may be made in the construction of said cap-plate as will fall within the invention.
The closure has an inwardly extending tongue D also tapered toward its extremity, as indicated in Fig. 6, so that it will have a long driving fit into the arm and this said tongue preferably has its position in the lower part of the arm, or whlch is to carry the lamp, and carries an at least that part exteriorly threaded extension or nipple E whose threaded part is located exteriorly ot' the arm A, as indicated at F, said nipple being provided with a bore As clearly illustrated, the arm A is provided in its lower wall near its end with a hole H somewhat larger in diameter than the nipple E through which said nipple can be inserted and within which it is susportions pended. This nipple, as shown, and as stated previously, may be a part of the clo sure 13, or its tongue D, or it may be threaded into the latter as indicated at J in Fig. 5 in which figure the said member is represented by K, the hole in the arm being indicated by H. Whendriven into place within the arm the closureis firmly held by friction through the extension C, its side C, and said tongue D, and it will be noted that when in its normal posit-ion the nipple lies freely within the hole H and does not touch the arm.
The lamp socket indicated at L is spaced from the arm and although the position of the latter in this respect is not important it does not of necessity help to hold the tongue D and the arm together.
In assembling the device the several operations represented in Figs. 3, 2 and 1 respectively are followed. In said 3 it is noted that the tongue D has been inserted in the end of the arm with the nipple opposite the hole H, and in Fig. 2 it has been carried into the lower part of the arm to place said nipple in said hole I-I, while in Fig. 1 the extension C is inserted into the end of the arm and driven up to its normal position. The hole is large enough to permit the nipple to enter it while the top part of the extension C is outside of the arm as shown and so that the extension may afterward be pushed to its place thus giving the nipple suflicient room to shift laterally in both the assembling and disassembling operations. In disassembling, of course, the same movements are followed but in .the reverse order. It is clear that if we resort to extending the hole H into a slot having an outer open end, the tongue and its nipple may be slipped directly into position.
Our device is exceedingly simple in construction and we have a minimum of parts which admits of a device of this kind being made at a very low cost and the time necessary to assemble or disassemble is practically nothing. But where a device is made up of parts so arranged that all are clamped onthe arm together much time is required to assemble them and complications of various kinds arise and the time necessary for assembling, as well as the cost, is greater 1n comparison.
As intimated, it is not our wish to confine ourselves to the exact structures herein described and show-n since such changes may be made as will fairly lie within the scope ofthe invention and its claims.
Having described the invention we claim 1.
