4 Claim.

This invention relates to a portable lamp and has for its principal object to provide such a lamp which is at the same time attractive and durable and very readily attached to and detached from a wall.

A further object is to provide for an effective distribution of weight and to reduce the likelihood of accidental forcible detachment from the wall which, unless provided for, in a fixture of such lightweight, might detract from its utility.

A further object is to provide novel means for holding the electric cable in proper position and to prevent such strains as might cause it to be detached from the lamp or to be abraded at the point of connection thereto.

Other and more limited objects will become apparent from the following description taken in connection with the accompanying drawing in which Fig. 1 is an elevation and Figs. 2, 3 and 4 are sections on the lines 2-2, 3-3 and 4-4 respectively of Fig. 1.

Referring now to the accompanying drawing, the numeral 10 indicates schematically a wall to which the device is attached and .11 indicates a .push pin adapted to be pushed by hand into the wall 10 and form a support for the lamp and bracket. By the term push pin is to be understood a headed member which is provided with a narrow pin portion suiiiciently sharp and of sufilciently small diameter that it may be readily inserted by hand into a wall of wood, plaster or the like. As shown, it may be provided with a head 12 of metal or glass having ornamental characteristics and provided with a thin sharp steel point adapted to enter the wall.

The lamp supporting bracket indicated generally by the numeral 13 maybe of Y-shape having one of the upper branches 14 curved into circular form and provided with a bayonet slot 15 adapted to receive the head portion 12 and also provided adjacent the inner section of the upper branches of the Y with an opening 16 through which the cable 1'7 may pass and be frictionally clamped at 18 between the upper branches of the Y. The other upper branch 19 is provided with an opening adapted to receive a threaded extension 20 on a lamp socket 212,- The lower branch 22 of the Y may extend downwardly and be provided with a transverse member 23 having wall engaging portions 24 affording a laterally extended engagement with the wall which will tend to prevent rocking of the bracket. The member 23 is connected with the lower-branch 22 as indicated at 25 and spaces such lower branch from the wall a sufficient distance to allow the cable 17 i1 5 1 2 1! the spirit of my invention and that I am to pass between such branch and the wall and between the wall engaging portions 24. One of the upper branches of the Y may be continuous with the lower branch thereof and the other upper branch secured in position by a C shaped member 26 extending around the 'two branches and riveted thereto as indicated at 27.

The lamp may be held in position by a nut 28 threaded on the extension 20 and preferably is provided with a shade 29 of the type which at- 5 taches by clamps to the electric bulb.

It will be noted that the cable 1'? extends from the socket 21 along the upper branch 19 and passes through the opening 16 where it is clamped with sufiicient firmness to support the weight of 7 the cable and then along the lower branch, alwaysin the plane on the bracket, and between wall engaging .portions24, merging from the fixture at a'point directly beneath the push pin 11. It will thus be seen that the weight of the cable is supported in a manner to exert pressure on the push pin vertically downwardly along the line very close to the wall. In this way, it is prevented from exerting a component tending to withdraw the push pin. In this way, the fixture so is able to withstand a considerable jerk on the cable without becoming disengaged from the wall in spite of the fact that its connection thereto is too precarious to be used in connection with a fixture of heavy construction or one in which 35 the cable would extend directly downwardly from the socket. In order that there may be no undue downward forces exerted on the lamp socket itself, such as would-result from a chain operated switch, I provide a transversely extending o push button switch 30 to control the lamp, this being more convenient than a switch in the cable and not increasing the-weight of the fixture. The bracket itself is made from light weight sheet metal strips which may' be somewhat curved for additional strength. While it is desirable to employ the push pin, in fact one-of the important features of the lamp, it is obviously possible to support the fixture on a more permanent support, and except for the undesirable feature of installing such supports, does not detract from the utility of the device.

From the foregoing, it will be obvious that I have provided a lamp which is movable from place to place with the utmost facility and which is well adapted for its intended purposes and while I have shown and described the preferredform, I wish it understood that changes may be made in the construction thereof without departlimited only in acco claims.

Having thus described my invention, what I claim is:

1. In combination, a Y-shaped, lightweight bracket having a lightweight electric lamp and shade mounted upon one of the upper branches, the other upper branch being curved and provided with a bayonet slot and also provided with an opening adjacent the intersection of the upper branches, the lower branch being provided with a pair of transversely spaced wall engaging portions bent toward the wall whereby to space the adjacent bracket portions from the wall, and an electric cable connected with said lamp and pass ing through the said opening adjacent the interdance with the appended section of the upper branches and between said.

wall engaging portions.

2. In combination, a Y-shaped, lightweight bracket having a lightweight electric lamp and shade mounted upon one of the upper branches, the other upper branch being curved and provided with a bayonet slot and also provided with an opening adjacent the intersection of the upper branches, the lower branch being provided with a pair of transversely spaced wall engaging portions bent toward the wall whereby to space the adjacent bracket portions from the wall, and an electric cable connected with said lamp and passing through the said opening adjacent the intersection of the upper branches and between said wall engaging portions, said cable being frictionally clamped between said upper branches.

3. In combination, a push pin, a Y-shaped, light-weight bracket having a lightweight electric lamp and shade mounted upon one of the upper branches, the other upper branch being curved and provided with a bayonet slot adapted to receive said push pin and also provided with an opening adjacent the intersection of the upper branches, the lower branch being provided with a pair of transversely spaced wall engaging portions bent toward the wall whereby to space the adjacent bracket portions from the wall, and an electric cable connected with said lamp and passing through the said opening adjacent the intersection of the upper branches and between said wall engaging portions.

4. In combination, a push pin, a Y-shaped, lightweight bracket having a lightweight electric lamp and shade mounted upon one of the upper branches, the other upper branch being curved and provided with a bayonet slot adapted to receive said push pin and also provided with an opening adjacent the intersection of the upper branches, the lower branch being provided with a pair of transversely spaced wall engaging portions bent toward the wall whereby to space the adjacent bracket portions from the wall, and an electric cable connected with said lamp and passing through the said opening adjacent the intersection of the upper branches and between said wall engaging portions, said cable being frictionally clamped between said upper branches.
