LAMP-SUPPORT.

. Specification of Letters Patent.

Patented Aug. 3, 1920.

Application filed. January 7, 1920. Serial No. 349,993.

To (ZZZ whom it may. concern:

Be it known that I, FnANoIs II. RosenrnLo, a citizen of the United States, and a resident of the city, county, and State of New York, have invented an Improvement in Lamp-Supports, of which the following is a specification.

The present invention relates to an improvement in lamp supports and has appli cation more particularly. to lamps of the character commonly used for illuminating Christmas trees and for other decorative purposes where it is contemplated that the use shall be of a relatively temporary nature. One object of the invention is to pro vide lamp support which may readily be attached to and detached from a Christmas t to or other similar object to be illuminated. A further object of the invention is to provide a support in the use of which it is possible to carry the conductors directly to the lamp without bringing them into contact with sharp edged or tLblflSlVQ articles. It also contemplated that devices embodying the present invention may permit the lamp socket to be readily adjusted to different positions and attached and detached without permanently distorting or injuring the support.

An embodiment of my invention is illustrated in the drawings which form a part of the present specification and in which,

Figure 1 is a plan view,

Fig. 2, an elevation,

Fig. 3, an elevation with lamp inserted and the support mounted,

Fig. a modification in elevation showing a socket support siidably adjustable with respect to the gripping member, and

Fig. 5, a plan view of the modification shown in Fig. 4.

Referring to the drawings, a device embodying my invention may comprise means for supporting a socket l which is commonly provided with perforations through which conductors 2 may be inserted to provide current for an electric lamp 3 of any suitable form. For the purpose of retaining socket l in an upright or in any other desired position, means are provided to engage saic socket and may comprise a socket receiving split cylinder 5 of any suitable material, preferably adapted to hold the socket in yielding engagement. Cylinder 5 may be provided with and rotatable upon a bearingor bearings 6 adapted to receive a pro- JGCiZlIlg portion 7 of a metallic soiral 8, the convolutions of said spiral being arranged to yieldingly grip a branch 9 of a Christmas tree indicated in Fig. 3, or other object to be illuminated.

The apparatus hereinabove described is illustrated and described in my co-pending application Serial No. 278,497 filed February 2-1, 1919, of which the present application is a division.

Where the form shown in Figs. 1 to 3 is used, the gripping spiral may be of large enougn radius to permit the lamp socket to be passed through it. The receiver or cylinder 5 may then be snapped into engagement with the socket l and mounted upon the projecting member 7 by sliding said member into engagement with the projecting bearings 6. If desired, the receiver 6 may be rotated about the projecting member 7 to any desired position.

In the devices described, the wires will pass longitudinally through the gripping spiral without coming in contact with abrading or cutting surfaces and the lamp, together with its support may be secured in any desired position without danger of exposing a live wire or short circuiting the lamp. The devices, by reason of the ad justability of their parts, also provide con enient means for varying the placing of fanciful lights such as those simulating fruits, animals and the like. i

The form of lamp support shown in Figs. 4 and 5 includes the cylindrical holder 1 having opposed perforations & through which a free end of the coil may be passed thus retaining the holder in upright position by coiiperation of one loop of the coil with another adjacent loop which normally engages one end of the holder. By sliding the holder 1 from one position to another on the coil, the position of a lamp supported thereby may be adjusted as desired. This form of support also presents advantages in use because the coils and holders may be wrapped compactly in the same package where the holder is removed from normal operative position on the coil and placed within it if the relative sizes permit.

I claim as my invention:

1. In a lamp support, the combination of spect thereto, said holder being adjustable ina plane normal to the central axis of the coil.

2. Ina lamp support, the combination of a coil of resilient material forming a spiral gripping member-and a lamp holder mounted on the coil and adjustable with respect to the central axis thereof and in a plane normal to said axis.

3. In a lamp support, the combination of a coil of resilient material forming a spiral gripping member and a lamp holder mounted on the coil andhaving opposed perforations alined to receive said coil and retain the support in slidable engagement therewith. V

4. In a lamp support, the combination of a coil of resilient material forming a spiral gripping member and a lamp holder mounted on the coil and havingopposed' perforations alined to receive said coil and retain the support in slidable engagement therewith retained on said coil by adjacent loops thereof, one of said loops passing'through perforations in the support and the other loop engaging one end of the support.

In testimony whereof have signed my name to this specification this 30th day of December, 1919.

FRANCIS M. RosENFELD.
