LAMP-SHADE surron'r.

To all whom it may concern Be it known that we, ANDRE-W the United States of America, residing at New Haven, in the county of New Haven and State of Connecticuhhave invented. a certain new and useful Improvement in Lamp-Shade Supports. of which the following is a full, clear, and exact description,

This invention relates to means for, sup porting lamp shades from lamps, such as the globes of electric lamps.

An important feature of the invention, is comprised in a device of the character referred to which is constructed of sheet ma terial and preferably of sheet metal, and embraces a pair of diametrically. opposite lamp-engaging members which are connected with a shade, and have suflicient resiliency to maintain engagement with the bulb of the lamp and at the same time to permit angular adjustment of the shade.

Another important feature of the invention consists in a lamp shade support of the character referred to in which the lamp engaging members terminate in circular clamping portions which are of sheet metal which is bent or distorted transversely of its plane circumferentially to provide a curved or rounded surface for contact with the lamp bulb, thereby strenghtening the clamping members and providing afinished surface on said members for engagement with the bulb.

Other features of the invention, such as important details of construction and combinations of parts, will be best understood from the following description, and the novel elements will bepointed out in the appended claims.

In the drawings:

Fig. 1 represents a lamp shade in section, and the shade support in elevation, said shade supportbeing in normal position on a bulb. I

Fig. 2 isa side elevation of the support taken at right angles to Fig. 1, and

Fig. 8 is an inverted plan View of Fig. 2.

The shade supporting device comprises two members made of sheet material, such as sheet metal. One of said members comprises a terminal flat portion 1, with acentral perforation, a downwardly inclined arm 2 and a circular bulb-engaging part 4, and the other member comprises a terminal flat J7. GAR" MICHAEL and JOHN R. Pn'rm-zson, citizens of portion 6' having a central perforation, a

downwardly inclined arm 3, and a terminal cir cular bulb-enga ingj portion 7. The Hattened portions 1, d

are arranged witl' their apertures in alignment and a clamping screw having shank 8, and head-1O is passed" through the aligned perforationsal'id other perforations 111 a washer 11 and thetop central portion of the shade 1 2, said'shanl': be- 9 I ing received in a threaded socket ofanor -a namental knob 14,-which cooperates with the screw in firmly securing the several parts together. 1 i

Preferably, the circular. bulb clamping parts 4, 7, are bent transverselyof the planes.

in which they lie to form convexly curved lamp-engaging ribs 15 which not only act to stiffen the members, but also provides a finished edge for engagement with the surface of the bulb B- When the parts of the shade support are assembled and clamped to the shade, as shown inFig. 1, it will be seen that the arms 2, 3 may extend outwardly and downwardly at aninclination and that the circular terminal portions like wise extend divergently, and engage the upper globular surface of the bulb. The maerial of which the members of the clamp is composed is preferably resilient sheet metal is tilted, within certain limits, but these limits are sufficient for all practical pur poses.

While we have shown the support as comchanges as fall within the scope of the following claims.

What we claim and desire to secure by United States Letters Patent is:

1. A shade support comprising, in combination, a plurality of flat sheet metal arms arranged to extend divergently from a central point of connection with a lamp shade, said arms terminating in circular lamp-engaging portions. said circular portions being a bent transversely of their planes to form oonveXly curved lamp-engaging surfaces.

2. A device of the class described, comprising, in combination, two arms of resilient sheet material arranged to extend divergently downward and terminating in circular lamp-engaging portions which are bent transversely of 1 their planes to. present curved lamp globe engaging surfaces, and means for rigidly securing said members to the inside central portion of a lamp shade.

set our hands this th {3. A device of the class described, comprising, in combination, two arms each having a terminal flattened portion provided with a perforation, and a downwardly ex tending outwardly inclined portion termiforations of said flattened portions andthrough a similar perforation in a lamp shade, and a clamplng knob to engage said means and cooperate therewith to secure said members to the shade.

In testimony whereof day of February A. D. 1923. 1 p i ANDREW J. CARMIOHAEL. JOHN R. PETERSON.
