HARP FIXTURE FOR LAMPS.

Application filed January 27, 1922. Serial No. 532,255.

To all whom z'tjmay concern: I Be it known that I, CORTLAND W, DAVIS, acitizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harp Fixtures for Lamps, of which the following is a specification. Y

The invention relates to harps such as are employed for pendently supporting lamps and lamp shades,; objects thereof being to produce a harp which is so constructed as to simplify the construction of the component parts, to render the assembling of the parts easy for unskilled labor, and to secure compactness in packing for shipment, whereby the users of lamp-supporting devices may be able to secure harps of convenient construction at a minimum cost. The lamp harp of my invention contains pieces of metal made according to pre-determined designs of such character that they may be readily set up by the user and united by the use of screws or other simple devices without the exercise of more mechanical skill than is possessed by the ordinary individual. The several parts are stamped or otherwise fashioned into final shape at the factory, and are ready for the assembling operation by the user without alteration.

The harp includes a top bracket, side bars having at their upper ends holes into which malleable lugs of the bracket extend, a shade-supporting ring secured to the side bars by bolts and carrying clips and screws for retaining a shade fixedly in position, and a lamp-supporting ring attached by bolts to the lower ends of said side bars 'for receiving the bowl of a lamp. These rings are recessed to receive the side bars, and both the rings and the side bars are made from flat stock metal which requires no machining.

The invention will be best understood if reference is made to the accompanving are of different sizes, but to afford room for the bowl of a lamp and also, give to the harp a pleasing ornamental design. Q

The bracket2 is made of flat malleable metal, and is provided with a'hole 3 for the reception of a sustaining hook and with lugs 4 extending through holes 5 in-the inwardly bent upper ends 6 of; the side bars 1, the-extremities of these lugs being upset to insure a secure union of the parts.-

The lamp ring 7 is made adjustable forconvenience in inserting a lamp bowl, but the means of adjustment constitutes no part of the present invention. This ring is bent at diametricallv opposite sides to form inner recesses or seats for the lower ends of the side bars 1, screw bolts 9 extending through coinciding holes in the ring and the side bars being used'to fixedly unite these elements.

The shade ring 10 is bentv to form diametrically disposed external recesses 11 for the reception of the side bars 1, and the union of the parts is effected by screw bolts 12 extending throughcoinciding holes in the ring and the side bars. Clips 13 and screws 14, constituting no part of this invention, are attached to the shade ring for the purpose of supporting and looking a shade in position-on the harp.

The shade ring 10, with the external recesses 11 and the clips 13, provides a support for a lamp shade of a diameter large enough to mount a shade large enough to pass down over the outwardly-bent sections of the upper end of the side bars 1 to the shade support. The lamp rin 7 with the inner recesses 8 allows the attachment of the side bars 1 without interference with the support of a circular ilamp bowl from the upper edge of the lamp ring 7.

From the foregoing it will be seen that the several parts of my harp are, with the exception of thebracket 2, made from common flat metal strips which have merely been bent to the required shapes and perfo rated at suitable points for the reception of the respective retaining devices, and that the bracket is of simple character requiring no particular skill in its production since it may be stamped in a usual manner. When the harp fixture is packed ready for trans portation tothe consumer, it will be seen that it may be assembled ina package of relatively small dimensions as the shade ring 10 and -tl'ieilamp ring 7, 111 ese a1-ab1e complete entities that may bel'aid flafi'ivit-h the side bars. The assembling of the fixture is easily accomplished by the c0nsumer with t the aid cf a s ci ew fdfivei' only. I

Having thus assented myihvenaen', wine I claim is: I

1. A harp fixture including side bars, a

shade band having open external"recesses disposed between and receiving said side harp. 7
