CONVERTIBLE BED AND TABLE LAMP Filed April 23. 193 1 INVENTOR gEY 'WJZTORNEY Patented Dec. 27, 1932 UNITED STATES LOUIS CRANE, F BRONX, NEW YORK CONVERTIBLE BED AND TABLE LAMP Application filed April 23, 1931. Serial No. 532,216

This invention relates to lighting fixtures in general, and particularly to convertible lamps.

The main objects of my invention are to provide an inerpensive device of this kind, which may be employed as either desk lamp or bed lamp, and which is so constructed as to permit exchange or replacement of parts without the employment of tools, and which possesses provisions for directing light wherever desired, for increasing or reducing the cone of light emanating from the lamp and for entirely shielding the light without switching off the current.

The foregoing and still further objects will become more readily apparent as the description of my device progresses, in connection with the accompanying drawing, forming part of my disclosure, but not intended to limit my invention to the actual showing, and

in which:

Fig. 1 is a front elevation of my device in one of its preferred embodiments, in the position when used as a desk lamp, portions of 5 which are shown broken ofi.

Fig. 2 is a side elevation thereof.

Fig. 3 is a cross sectional view through the lamp taken on lines 33 of Fig. 1.

Fig. 4 is a similar cross sectional View through my device, used as a bed lamp.

Fig. 5 is an enlarged detail cross sectional view, illustrating the typical manner of connecting the lamp parts together.

Referring now to the figures, numeral 10 denotes a one piece wire support composed of two loops 11, adapted to engage the structure of the lamp, from which the wire continues in the form of two parallel legs, curved ends diverted from the loops as shown at 12 are swung back in semi-loops 13, from which the wire extends in a slight curve 1% to the cross member connecting the legs.

The body of the lamp comprises a cylindri- AK cal member 15 provided with an opening 16. The inner surface of member 15 is preferably highly polished or coated so as to serve as a reflector. lVithin the cylinder is op-eratively mounted a shutter 17, which is curved in conformity with the inner curvature of the cylinder and which extends in width beyond theside edges of opening 16 and is provided with a stop handle 18 for operating it and for limiting its movement within the cylinder between one horizontal edge of the opening and the other. I

Adapted to extend from the ends of the cylindrical body 15 are two hollow, draw- n members 19 and 20, identical in form, dimensions and construction. Their engaging ends are provided with grooves 21 designed for receiving the looped ends 11 of the lamp support. Next to the grooves are provided annular enlargements 22 serving, together with loops 11 and the edges of cylinder 15, as limitmg means for end members 19 and 20 for preventing their inward movement beyond a desired limit.

Extending inwardly from the grooves of the end members are cylinder engaging portions 23, intended to be held in the cylinder by friction. Their edges 24 are bent inwardly so as to provide annular recesses with the cylinder, with which register the crimped edges 25 of shutter 17. These recesses form guide grooves and facilitate, together with the crimped edges of the shutter, the latters smooth movement within the cylinder while at the same time exerting sufficient friction between the three lamp members, for keeping the shutter at any adjusted position.

Both end members 19 and 20 are interchangeable, although the latter member is designed for accommodating a light bulb. The extreme outer end portion of member 20 is perforated, for receiving the nipple of lamp socket, held in place by bushing 26. End member 20 is further provided with means for accommodating some sort of operating mechanism, whereby the switch within the lamp socket may be actuated. In Fig. 1, I have illustrated a turn button 27 projecting through the body of member 20, it is obvious however that a chain or press button may be readily substituted.

As the drawing plainly indicates, the entire lamp fixture may be rotated either wholly or in part within loops 11 of the wire frame. The end members may be switched to either end. By rotating the cylinder and Wm by adjusting the shutter the angle of light 1 355 ingly suspending said fixture by its end membed lamp.

emanating from the device may be altered in any desired manner as indicated by broken lines in Figs. 3 and 4. The support of the fixture presents its use in the form of a table or desk lamp or as a bed lamp. The bulb holding end member may be entirely removed and used independently of the rest of the fixture.

All the above advantages are readily apparent. Nevertheless, my invention is capa- H ble of changes and improvements which may become necessary in the course of manufacture, and be it understood therefore that I shall have the right to incorporate such improvements within the broad scope of my invention, as evidenced ,from the annexed claim. I

A In a device of the class described, a lamp fixture comprising a fixture body and a fixture support, the former composed'of acylindrical centre portion provided with an opening, a" shutter operatively. mounted within that portion and behind said opening and adapted to slide acrossthe latter and having 7! limiting means for defining its operation, in-

terchangeable endv members associated and in frictional engagement with said center portion, means provided with said end members for forming guides for said shutter,

other means provided with said end members for accommodating and engaging said fixture support and for limiting their inward movement relative to said centre portion, said fixture support having provisions for revolvbers and being so formed as to facilitate positioning of the fixture either upon a platform or table for use as desk lamp, or its suspension from a bed end or the like-for use as Signed at New York, in the county and State of New York, this 30th day of March,
