Application filed November 4, 1915. Serial No. 59,546.

source may be adjusted to a great variety of positions. A further object of my invention is to provide a device which may be 1 supported in a horizontal position, as .on a table or desk, or which maybe suspended in a vertical position from the wall or from any other support, such as an article of furniture. My invention provides a device which may be very eflectively'and conveniently used as a desk lamp, a table lamp, a shaving lamp, a bed lamp, and in short for any purpose requiring concentrated illumination.

According to my invention, the lamp socket, which is preferably provided with means for adjustably supporting a suitable reflector extending longitudinally thereof, is hinged or otherwise pivotally attached to a supporting means. The latter is composed of a plurality of legs, preferably three in number, which are preferably pivoted together so that; they may be telescoped. These legs are so shaped that they willsupport the rest oft-he device upon a table or desk. One or more of them is also so shaped that the device may be suspended thereby from a hook or similar wall support, or from an article of furniture, such as a shaving mirror. The construction and dimensions of the parts are preferably such that after the telescoping of the legs they may be folded so that the end portions will be received within the reflector, thus providing a collapsed structure which may be very conveniently transported.

Further features and advantages of my invention will appear from the accompanying drawing, in which Figure 1 is "a top plan view of a device comprising my invention; Fig. 2 is an elevation of the lamp in use, as a desk or reading lamp, and Fig. 3 is an elevation of the same when.collapsed.

Referring now to the drawing, 10 is an incandescent lamp socket upon which is supported areflector 11, which extends longitudinally of a lamp, not shown, which may be inserted in said socket. The said reflector 1S preferablyj'sos'supported that it may be turned in a direction transverse to that of the lamp to any desired angle. The socket 10 is attached to a member 12 of a hinge 13, the other member 14 of which is rigidly attached to one and of a leg 15. The other end of the leg has a hook-shaped transversely extending portion 16 and an offset end .17, which is preferably parallel to the main ,portion 15. Other legs, preferably two in number, 18 and 19 are so connected with the leg 15 that they serve as auxiliary 79 supports. Preferably, the ends of the said legs are similarly shaped at 20 and 21. respectlvely, to the end portion or the leg 15. The legs 18 and 19 are preferably each so pivoted that they may be swung in a direction parallel to the extension of the leg 15.

In the form shown the ends of the legs 18 and 19 are supported between the ends of hinge member 14 and leg 15, pivot pins 22 and 23, respectively, passing therethrough. so

The end 17 of the leg 15 is preferably slotted, as at 24, so that it may be engaged with a hook or similar supporting means. The ends of the legs 18 and 19 may be perforated, as at 25 and, 26, respectively, so 35 that if desired the device may be fastened to the wall or in any similar desired position.

As shown in Fig. 2, the parts are so adjusted that the device is suitable for a desk lamp, the legs resting upon the top of the desk and the. reflector being so adjusted as to cast light downwardly upon the table. It will be apparent, also, that with the parts in the position shown this device would serve very efflciently as a piano lamp. It

will be-apparent, also, that by swinging the, lamp to the position shown in dotted lines, or at any other desired angle, a conveniently adjustable reading lamp may be provided.

The above described device may be suspended from a hook or similar wall attached support by engaging the slot 24 therewith. The lamp proper may then be swung to a position more orless transverse to the general extension of the legs, the auxiliary legs 18 and 19 in such case serving as spacing members to hold the lamp out from the wall. It will be apparent, also, that the hook-nheped portion 16 of the leg iii mey be placed over the top of a mirror or of a bed, and the lamp so adjusted as to direct light downwardly. It will be obvious, also, that in some cases this suspension may be more easily secured by using the supplementery legs 18 and 19 for engagement with the mirror or other support While the member 15 serves as a spacing or abutting member.

As shown in figs. 1 and 3 the above described structure comprises means whereby the legs 18 and 19 may be swung under the leg 15, these legs being shown in the intermediate position in dotted lines in Fig. l. The legs may be folded over so that the main portions thereof are in close proximity to the socket 10, while the ends of the opposite portions enter the reflector 11. Such collepsihility allows the device to be very conveniently transported as it takes up 2, very small space and has a minimum of projecting parts.

Whet I claim and desire to secnre by Letters Potent of the United {states is:

1. In a portable lamp, the combination of on incandescent lamp socket, and s siipp yn';-

ing means comprising s. nged to said socket and pair of othe' e 's having their ends pivoted to the hin cd end of she first mentioned leg.

2. in a portable lamp, the combination of en incandescent lamp socket and a. supporting means comprising a leg having a hookshsped end hinged to said socket and a, pair of other legs having their ends pivoted to the hinged end of the first mentioned le 3. in a, portable lamp, the combination of an incandescent lamp socket having attached thereto a longitudinally extending reflector, and a supporting means hinged to said socket comprising a plurality of legs having transverse end portions, said legs being pivfeted together so that they may be telescopecl end the aforesaid parts being so mounted that said legs may be extended with their transverse end portions extending away from said socket or may be telescoped and folded over with the said end portions extending into said reflector.

in Witness whereof, i have hereunto set 1 my hand this 2nd day of November, 1915 WLFLTD to li ILEY,
