My'invention relates to improvements in electric portable lamps and has reference particularly to the construction of a wall lamp or sconce, which is capable of being readily attached and 5 detached from the wall, and which lends itself to an almost endless number of designs appropriate to this type of lighting fixture.

Portable wall lamps have already been devised and used with an extension cord and plug for 10 connection in the ordinary electric wall sockets and these lamps have found a wide market, because of the fact that one may avail oneself of the beauty and charm of side wall electric light fixtures without the necessity of inter-wall wiring l5 installations and the expense therefor. The present type of fixture has the added attraction that it is portable and may be made available wherever there is a wall socket to receive the plug connection.

2 The object of the present invention is to improve upon the known types of portable wall fixtures by making a bracket of one piece of springy material, one arm of which is longer than the other so as to bring the bracket under tension 2 when it is in attached position to hold it firmly against displacement and to aid in maintaining its proper upright position.

A further object of my invention is to provide a slotted aperture in the fixture which will en- 30 able the electric extension cord to take its proper position without requiring it to be threaded through a series of openings with the result that the plug may be attached to the cord before assembling the lamp bracket.

35 I accomplish these objects by means of the embodiments of my invention hereinafter described in the specification, set forth in the appended claims and illustratively exemplified in the accompanying drawing, in which 4 Figure 1 is a side elevational view of the portable wall lamp;

Figure 2 is a back view of the same; and

Figure 3 is a perspective 'view of a modified form of bracket.

45 Referring to the drawing and particularly to Figures 1 and 2, II] denotes a side wall to which the wall bracket may be attached and I I the push pin or tack which has been placed in the Wall and forms a support for the bracket.

5 The bracket, designated I2, comprises a substantially V-shaped member bent from a single strip of springy material, preferably steel, one arm I3 being longer than the other arm I4 and both arms having their free ends curved into 55 coils I5 following the same direction. In position for use as a bracket the V-shaped member is disposed with one arm directly above the other, the shorter arm I4 being the uppermost and at right angles to the wall I while the longer arm I3 projects downwardly at an inclination towards a:

the wall. The normal position of the longer arm I3 when not under tension, i. e., when free of the wall, is substantially that indicated in dotted lines in Figure 1, but when the free end of arm I4 is brought into contact with the wall, the arm I3 springs to the full line position and is held under tension and in frictional contact with the wall at its free end. The curved portion of the coil I5 of the upper and shorter arm I4 abutting the wall is provided with an orifice I6 to accommodate the passage of the head of the pin II therethrough and to allow the head to seat itself against the inner curved surface of the coil and to provide a more or less tension hold of the pin upon the bracket. The longer arm I3 is provided with an elongated slot I1 extending about the curve in the coil I5 abutting the wall, the slot I'I allowing the electric cord I8 to pass from the space between the arms I3 and I4 and to a point below the bracket without the necessity of threading it through any opening in the lower arm.

Any type of electric fixture may be mounted upon the upper arm I4, but for purposes of illustration I have shown a lamp comprising a ball bottom I9 set in adepression 20 in the midportion of the arm I4, lamp socket 2| mounted upon the ball I9, an incandescent bulb 22 in the socket and a shade 23 carried by the bulb. The socket ZI is of the type provided with a switch and bottom 24. The ball bottom I9 is attached to the arm I4 by means of a screw connection 25, which allows the cord I8 to pass therethrough into the space between the arms I3 and I4, and which passes through an opening 26 in the arm to receive a nut 25 capable of being screwed over the connection and against the under-face of the arm to firmly hold the lamp in position. The free end of the extension cord I8 is provided with the usual plug in connection 28 mounted in the wall [0 adjacent the floor.

Referring now to Figure 3, the bracket in this embodiment comprises a straight wall portion 29 and an outwardly curved portion projecting from the wall in a curved line to form the longer arm I3 the shorter arm: I4 being constructed by turning the material at the outer end of arm I3 upwardly and then backwardly again upon itself. The free end of the shorter arm I4 is curved in a coil 30 having an orifice 3| to accommodate the pin H. The outer end of the shorter arm W is provided with an orifice 32 to receive a lamp fixture 33, the cord l8 projecting downwardly over the face of the longer arm l3 and being guided to a point below the bracket in an upright slot 34 in the straight wall portion 29. The lower end of the longer arm 13 is provided with a projecting arm 35 disposed at right angles to the portion 29 and arranged directly beneath the other arms l3 and M Mounted on the top of this arm 35 is a dish or any other receptacle 36 for a flower pot, vase or the like.

To install the present bracket, the pin II is,

placed in the Wall l at the desired location and the opening l63l in the shorter arm M, M isplaced over the head of the pin which is-then.

allowed to project through the opening. The bracket moves down slightly until the top wall of the opening I6-3l rests upon the stem of the pin and the head engages the material about the opening. When the upper arm l4, M is set the latter will be at right angles to the wall I0 and the longer arm I3, l3 will spring outwardly and downwardly until it is in contact with the wall to hold the bracket in position.

Having now described my invention and the manner in which the same is operated, what I claim and desire to secure by Letters Patent is:

1. In combination, a bracket of springy material having a pair of arms, one thereof being shorter than the other and adapted to support a lamp, the free end of the longer arm being slotted to accommodate an electric cord from the lamp, and means to attach the free end of the shorter arm to a supporting surface,while the longer arm springs away from the shorter arm to bring its free end into frictional contact with the supporting surface.

. end of the said longer arm, said supporting arm being inclined with respect to the supporting surface and adapted to support a weight in orderto produce stable suspension of the bracket.
