SU PPORT FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 449,902, dated April 7, 1891.

Application tiled June 19, 1890. Serial No. 355,920, (No model.)

To all whom t may concern,.-

Beit known that I, J AMES WATSON EASTON, a subject of the Queen of Great Britain, and a resident of the city, county, and State of New York, have invented cert-ain new and useful Improvements in Supports for Electric-Arc Lamps; andI hereby declare that the following is a full, clear, and exact description thereof, reference being had to the acto companying drawings, forming part of this specification.

The object of my invention is thc provision of means for supporting` an electric-arc lamp which will permit the lamp to be readily suspended at any desired height and will afford a firm support for it and yetallow the lamp to swing freely in all directions without becoming detached from the support.

To this end my invention consists in the 2O novel details of construction and arrangement and combination of parts hereinafter described, and specifically set forth in the claim.

In the accompanying drawings, Figure l is z5 a view, partly in section, of my invention as used for supporting a lamp for indoor illumination. Fig. 2 is a plan view thereof as seen from beneath, and Fig. 3 is a detailview of the swinging links or loops by which the 3o lamp is held in place.

Similar letters of reference are used in all the views to designate corresponding parts.

To the ceiling of the room or to any other desirable point is attached the plate A, which forms a suitable support for the binding-posts B, to which the terminals of the line-wires are secured, and for the switch C and its connections, by which the circuit is maintained when the lainp is not in use. To the plate A are also secured two eyes or rings D D, within which are suspended the s winging loops E E, which are preferably constructed of wire bent into substantially the shape shown in the drawings; but I do not wish to limit myself to any specific material therefor. To the rod or extension F, which forms the upper portion of the lamp-frame, are secured two projecting lugs or ears G G, each of which is adapted to rest in the bottom of one of the 5o loops E, as shown in Fig. l.

` The upper end of extension F is made of such shape as to be readily insertible between the loops, and as the lamp is raised the loops are separated and forced out toward the position shown by the dotted lines iii-Fig. 3, and when the lugs come intocontact with them the loops spread out over the top of the lugs and fall into place under them. IVhen it is desired to take the lamp down, it is lifted slightly' 7o and turned so that the lugs G are brought between the loops E, and thus released from engagement with them. Vhen the lamp is in positionand ready for use, the bindingposts B are connected to the binding-postsf on the lamp by suitable conductors, which are disconnected when it is desired to take down `the lamp.

I have shown the lamp suspended from the ceiling of a room', through which the exten- 8o sion F projects into the space between the rafters; but the openings through the plate A and the ceiling are not necessary when the lugs are fixed on the upper extremity of such extension.

It will thus be perceived that while myimproved device isof the most simple construction it affords a perfectly secure support for the lamp, since, owing to the form of the loops E, which prevents any lateral or twisting. 9o movement of the lugs G, the lamp will not be disengaged by any such movement accidentally imparted toit; but the lamp must be lifted bodily to release the lugs from engagement with the loops. At the same time as the lamp is supported so as to swing freely in all directions it will accommodate itself to any sudden shock or movement that may be imparted to it without becoming disengaged f rom the loops. Furthermore, thelamp roo stantinlly the shape shown, a support therefor, and the extension F, provided with the may be putin place or removed instantly without any manual manipulation of the suspending dVCQS- lugs G, adapted to rest in the bends of the 1 do not wish to confine myself to a device loops and project over the sides thereof, Wherefor` supporting electric lamps only,because it by the lugs are prevented from receiving any may be used to support any object to which lateral or twisting movement While supported l the lugs G can be attached. in the loops, substantially as and for the pr- Having thus described my invention, what l poses set forth. I claim :is new, and desire to secure by Leti ters Patent, isy E In a supporting device, the combination of p two independent swinging` loops E E of sub- JAMES W. EASTON. Witnesses:
