ELECTRlG LAMP ATTACHMENT Filed June 8. 1932 73 77 v S31/wanten oz//J mw/5y.

Patented July 4, 1933 UNITED STATES LOUIS A. LINDEYfOF BROOKLYN, NEW YORK ELECTRIC LAMP ATTACHMENT Application ined June s, 1932. serial No. 616,018.

This invention relates to improvements in electric lamps, and more particularly to an attachment for floor and bridge lamps.

The primary object of the invention resides in attachments which may be detachably supported upon a floor or bridge lamp to position a light directly above a bridge table or'other` playing or writing surface in 4order that the illumination produced thereby will be available to persons seated about the table. Thus, the present practice of positioning two or more lioor lamps about the table tosupply the proper illumination on the persons seated thereabout is dispensed therewith.

Another feature of the invention is to provide a lamp attachment which may be expeditiously set up for use when desired, and removed and stored away in a compact man- QO ner.

A further object is the provision of an extension arm for floor lamps which may be adjusted relative to the floor lamp to extend Yto various lengths therefrom.

A still further object of the invention is to provide yan attachment having the above features which is simple of construction, in-

expensive of manufacture, and which doesl not detract from the artistic furnishings of a room.

With these and other objects in view, the

invention resides in the certain lnovel construction, combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a perspective view of my invention in use upon a floor lamp.

Figure 2 is a front elevational view of the same.

Figure 3 is a horizontal sectional view on the line 3 3 of Figure 1.

Figure 4 is a detail vertical longitudinal sectional view through the extension arm.

Referring to the drawing by reference characters, the numeral 1() designates my lamp attachment in its entirety which is shown in the drawing as attached to a oor lamp A which includes the usual base B from which a standard or post C rises vertically, while secured at the top of the standard and extending outwardly therefrom is the usual fixture bracket D which is provided with an electric lamp socket E at the outer end thereof. In the present instance, a goose neck yshaped bracket has kbeen shown but other shapes and styles may be provided.

The attachment 10 comprises an elongated 60 arm 11 embodying a tubular section 12 which telescopically,receives a rod section 13 whereby the arm 11 lmay be adjusted to various lengths.v A set screw 14 is threaded into the tubular section 12 and when tightened 65 serves to prevent sliding movement of the sections 12 and 13 relative to each other'. The outer free end of the tubular section 12 is provided with a spring clamp or clip 15 which when the attachment is in an applied position engages the standard C of the floor lamp A. The outer free end of the rod section 13` is provided with a hook 16 which removably supports an electric lamp socket 17, the same being provided with an eye 18 75 for engagement with the hook 16. An electric lamp 19 is screwed into the socket 17 while a shade 2O is supported by the socket in the usual well known manner.

Tn order to support and brace the arm 11 80 in a substantially horizontal position when attached to the lamp A, T provide a iexible brace member or cord 21, the ends of which art provided with eyes 22 which are slipped onto the arm 11. Gne of the eyes 22 is dis- 85 posed upon the tubular section 12 while the other eye is arranged on the rod section 13 and abuts the inner end of the tubular section 12. By fastening the ends of the cord 21 to the arm 11, a loop is formed which is 90 engaged with the bracket D of the lamp whereby the arm 11 is braced and suspended in a substantially horizontal position.

Tn Figure 1 of the drawing, T have illustrated in dotted lines, a portion of the bridge table F and the lamp attachment is adjusted so that the electric lamp or light 19 is disposed directly above the table whereby the light produced thereby is available to persons seated about the table. This dispenses with the present practice of positioning two or more bridge lamps about the table, iyhich lamps are probably moved from their set position in a room which exposes the lamp cords over which persons `moving about the room may trip.

For supplying electric current to the lamp socket 17 I provide an electric cord 23 which is electrically connected to the terlninals of the socket 17 While the opposite end carries an attachment plug 24 Which is removably connected to the socket E. By turning on the current through the socket E, the same may flow to the socket 17 providing the switch of the said socket is turned on and the lamp 19 is of course lighted.

From the foregoing description, it will be seen that the attachment may be quickly attached to a loor lamp When desired,and when so attached does not detract from the artistic furnishing of a room. When the attachment is not desired for use, the same may be removed and the floor lamp A used for its usual purpose. n

Whereas I have shown I' deem to be the most desirableembodimentof my invention, I'Wish it to be understoodthat various changes that come Within the scope of the appended claims may be resortedto if desired. n

Having thus described the invention, -Wliat I claim as new and desire to secure by Letters Patent is 1. In combination with a floorla'mp having an upstanding standard, and a bracket extending Atherefrom on which an electric lamp socket is mounted, an extension device and described what comprising an arm, means carried by one end of said arms for detacliably engaging said standard, an electric lamp socket on the other end of said arm, an electrical connection between the socket on said bracket and the socket on said arm, and brace means supporting said arm in a substantially horizontal outstanding position from said standard.

9.. In combination with a floor lamp having an upstanding standard and a bracket extending therefrom, an extension device comprising an arm, means carried by one end of said arm detachably engaging said standard, an electric lamp socket carried by the other end of said arm, and a flexible brace member looped over said bracket With its ends slidably connected to said arm at spaced distances apart.,

8. An attachment for floor lamps comprising an arm, a spring clip carried by one end of said arm, an electric lamp socket carried by the opposite end ot said arm, and a flexible brace member having its ends secured to said arm at spaced distances apart.

4. An attachment for floor lamps'comprising an arm embodying a air of slidable telescoping sections, means or securing said sections against sliding movement, a spring clamp carried by one end of said rod, a hook at the opposite end of said rod for supporting an electric lamp socket, and a flexible suspension cord having its ends attached to said rod at spaced distances apart.

Signed at Kings County, N. Y., this 6 day of June 1932.
