LAMP

Filed Dec. 4, 1940 INVENTOR HARRY I. ALB/mm- I I gg ATTORNEY5 Patented Apr. 14, 1942 UNITED} STATES rarest errics 1 Claim.

This invention relates to lamps, and more especially it relates to electric lamps for desk or table use.

The lamp is of especial utility in situations where maximum illumination is desired, and

where local illumination is desired without the.

necessity for illuminating an entire room or a substantial part thereof. Thus the invention is especially useful for the illumination of typewriting machines, telephone instruments, drawing boards," and books and the like.

The chief objects of the invention are to promajor portion of the base being flat so as to rest flush upon a desk or other flat surface.

. Close to one of its ends the base 20 is indented vide an improved lamp having a supporting base I of such construction as to enable articles to be positioned close to the lamp standard; to provide a lamp having a base of such construction that articles conveniently may rest thereon and thus increase the stability of the lamp; to provide a lamp having a base of relatively simple construction that serves to conceal and protect the electrical conductor cord of the lamp; and to provide a lamp having a base that is composed of relatively thin sheet metal, yet which is firm and rigid. Other objects will be manifest as the description proceeds.

Of the accompanying drawing:

Figure 1 is a vertical sectional view of a from its bottom face to provide a raised portion 2| that extends from one lateral margin of the base to the other, said raised portion being substantially square in section so that the top thereof is horizontal and fiat, and is disposed in a plane parallel to the major portion of the base. To reinforce the raised portion 2| and thus to prevent flexure thereof, raised ribs 22, 22 are provided, said ribs extending transversely of the raised portion adjacent the ends thereof, and

terminating on the flat portions of the base laterally of the raised portion and closely adjacent the same.

The horizontal top wall of the raised portion 2| is centrally apertured to receive a tubular ferrule 24 that is secured therein, and the lower end of the standard member ID is threaded into the upper end of said ferrule so that the standard is supported thereby. The conductor cord lamp embodying the invention, the lamp shade being shown in elevation; and 1 a Figure 2 is a plan view of the improved lamp as seen from the line 2-2 of Fig. 1.

Referring to the drawing, there is shown a telescopic lamp standard comprising a tubular lower member ID and a tubular upper member II, the latter being disposed partly within the member Ill. The upper end of member III has a collar I2 threaded thereon through which the member H slidably extends, and a thumb screw I3 is threaded radially through said collar for engagement with said member H to retain the latter in properly adjusted axial position with relation to member [0. The member I I is formed with a longitudinally extending flat surface Ila on one side thereof, which surface is engaged by the thumb screw l3, the arrangement being such as to prevent angular movement of the member H with relation to the member ID. Threaded onto the upper end of member II is an elbow l4, and supported by the latter, at right angles to the standard, is a C-shaped bracket l5, the arms of which extend horizontally outwardly. The free ends of said bracket arms between them support a lamp shade l6, and within the latter is the usual lamp socket and lamp bulb (not shown). The conductor cord l1 extends from the said socket, through the elbow I4, and through the standard members II and Ill, said cord emerging from the latter at the bottom thereof.

The lamp standard is carried by a base 20 composed of relatively thin sheet metal, said base preferably being of oblong shape as shown, the

ll extends through the ferrule 24 and into the space below the raised portion 2|, the latter thereby constituting a tunnel for the cord to guide the same laterally and away from the major portion of the. base upon which articles may rest. The shade l6 and the major portion of the base 20 are determinately positioned, with the lamp bulb directly over said base.

When in use, articles may rest upon the thin, fiat base 20, as indicated by broken lines at 25, Fig. 1, without being tilted thereby, yet may be positioned so close to the standard as to obtain maximum illumination from the lamp thereon. Articles resting upon the base 20 serve to retain the latter in desired position, and also serve to prevent tilting or upsetting of the standard. The improved lamp is of relatively simple construction and achieves the other advantages set out in the foregoing statement of objects.

Modification may be resorted to without departing from the spirit of the invention or the scope thereof as defined by the appended claim What is claimed is:

A lamp comprising an upright standard, and a base for said standard, said base consisting of a one-piece structure'of relatively thin sheet metal of oblong shape formed with a transverse raised portion adjacent one end thereof extending from one lateral margin to the other, said raised portion being open at its ends and comprising a fiat horizontal top wall upon which said standard is centrally mounted, and flat front and rear walls disposed perpendicular to the main body of the base, said front wall constituting a stop means adapted to align papers and the like that may rest on the base, said raised portion constituting a tunnel for a conductor cord which extends into said standard.
