LAMP.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed December 11, 1920. Serial No. 429,985.

T 0 all whom it may concern:

Be it known that I, Gos'mvn E. VILLARET, a citizen of the United States, and a resident of the city of New York, borough of Man-' hattan, in the county and State of New York, have invented a new and Improved Lamp, of which the following is a full, clear, and exact description.

This invention relates to improvements in lamps, and more particularly to electric lamps, an object of the invention being to provide a lamp which employs but a single electric bulb and which functions to illuminate the room as well as give forth a diffused light for reading.

A further object is to provide a table lamp or other form of lamp in which the light from an incandescent bulb is deflected upwardly to illuminate the room and diffused downwardly and outwardly eliminating shadows and preventing glare t0 the eyes of those seated in the room.

A further object is to provide a lamp which can be manufactured and sold at a reasonably low price, which can be readily cleaned, which facilitates the removal of parts without disturbing other parts, which readily lends itself to ornamentation and variation of shape, design and materials, so that it can be made extremely attractive, and

which most efiiciently performs the func-,

tions for which a lamp is intended.

lVith these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements'of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view partly in section and partly in elevation illustrating a preferred form of my improved lamp.

Fig. 2 is an enlarged perspective view of one of the shade holding arms.

Fig. 3 is a fragmentary enlarged sectional view illustrating the manner of attaching one of the arms to its supporting ring.

Fig. 4 is a view similar to Fig. 1 illustrating a modification.

1 represents a pedestal or standard having at its pper end a globe receiving ring 2 provided with the ordinary set screws 3 to secure the globe 4: in place thereon. The upper end of the standard 1 is also provided within the ring 2 with a socket 5 for the reception of an electric lamp or bulb 6.

The globe 4 is preferably made of the shape shown; that is, it is formed with an enlarged or bulbous upper closed end 7 and with anenlagged orbalbpusepenlower end 8', the bulbous lower end 8 being preferably of greater diameter than the upper end 7, and both of these ends 7 and 8 being preferably of translucent material such as frosted glass, while the glass portion 9 connecting the two bulbous ends, is of clear glass. In other words, the globe 4 has a clear glass intermediate portion 9 with frosted or other translucent bulbous ends, and, as above stated, while this is a preferred shape, it is obvious that the invention is not limited to the precise shape of the globe. The globe is of such internal diameter as to accommodate the electric lamp or bullo 6 and permit a free removal and replacement of the globe over the same.

A series of shade supporting arms 10, preferably four in number, are secured at their lower ends to the ring 2 and curve or fiare outwardly and upwardly and at their freeendsvare provided with'channels 11 to receive and supportthe shade 12. The lower ends of these arms 10 are preferably secured to the ring 2 as shown most clearly in Fig. 3, by means of screws 13, the latter being countersunk in the ring 2 and screwed into tapped and threaded openings 14: in the arms 10.

The shade 12 may he ornamented and shaped as desired to give the desired orna-' mentation to the lamp and is made with a downwardly and inwardly projecting portion 15 which may or may not be integral with the main portion of the shade. This portion 15, which constitutes a reflecting portion, is of tapering or truncated conical form with its extreme lower edge preferably grooved as indicated at 16, and resting upon felt or other cushions 17 in the channels 11 of the arms 10, and set screws 18 are mounted in threaded openings 19 in the outer walls of the channels 11 and are projected into the groove 16 of the shade to securely hold the shade in position.

WVhile I do not limit myself to the precise design and shape or even to the precise material employed in the construction of the shade as I may employ any material or combinations of materials which are coming the inner taperingportion 15 terminat portion 15 of the shade.

will be noted t ing in a plane appreciably abovethe lower shade may be further ornamented by additional ornamental attachments, and in fact, the entire lamp-readily lends itself to a wide variation of modification, shape and design.-

In the modification illustrated in Fig. 4,.

the inwardly and downwardly projecting portion 155 ,ofthe shade 12 is supported directly upon the bulbous lower-end 8 of the secured to the support and having itsinterglobe 4 with an angle or' metal ring 20 interposed between the shade and the globe. In other essential respects, the lamps are alike and they function in the same manner.

With the preferred form of lam such' as shown in Fig. 1, it will be note that the shade can be removed without interfering with the globe and the globe can be removed without interfering with the shade, whereas in the modified form shown in Fig. 4, the shade can be removed, but the" globe cannot be removed without also removing the shade. In operation, the light from the electric lamp'or bulb 6 radiates directly through the clear glass portion 9 of the globe 4: and is deflected upwardly and outwardly by means of the inwardly and downwardly projecting This deflection of light serves to illuminate the room while the rest of the light is deflected downwardly and diflused by reason of its passage through the translucent bulbous portion 8 of the globe and through the translucent material of the shade.

With a lam .such as above described, it hat I not only secure an illumination of the room, but also secure a downward diffusion of light which is ample for reading and, at the same time, prevent glare of the lamp-to the eyes of persons seated in the room. With ordinary lamps while they afford suflicient light for reading, they give a glare which is extremelyobjectionable to those seated in the room. Furthermore, it will be noted that by reason of my improved construction, I am enabled to-employ a single electric lamp or bulb whichfunctions to illuminate the room, as well as give the necessary light for reading, and provide such a lamp structure that the light is diffused without shadows. I

It is obvious that with a slight modification the lamp mightbe modified for use as a gas lamp in which the same features of construction and general features of advantage can be carried out as those described in connection with an electric lamp.

Various slight changesmight be made in the general form and arrangement of the parts described'without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly'fall within the spirit and scope of the appended claims. 1

I claim: 1. A portable lamp, comprising a support, a globe on the support, a shade holder independent of the globe and connected to the support, and a shade located aroundthe globe and having at its upper end afdownwardly and inwardly projecting reflecting portion positioned around the globe and located upon said shade holder.

2. A lamp, comprising a support, a globe above the lower edge of the shade, and means independent of the globe supporting the shade with said inwardly projecting portion of the shade surrounding the upper portion.

only of the globe.

4. A lamp, comprising a support, 'a bulb socket on the support, a bulb inclosing globe removably secured at its lower open end to the support and having a transparent intermediate portion, outwardly and upwardly projectingarms secured to the support, and a shade having at its upper end a downwardly and inwardly projecting annular portion supported on said arms, 'the said" downwardly -and inwardly projecting portion' constituting an upwardly reflecting surface for the light rays passing through the transparent portion of the globe.

5. A lamp,-'comprising a support, a bulb socket on the support, a bulbinclosing globe removably secured at its lower open end to the support, outwardly and upwardly projecting arms secured tothe support, said arms having cushioned channels at their upper ends, set screws in said channels, and a shade having at its upper end a downwardly and inwardly projectin portion resting in the channels and secure by the set screws.

6. An electric lamp, comprising a pedestal, a ring at the upper. end of the pedestal, a bulb socket located centrally. of the ring, a bulb inclosing globe having its open lower end removably secured in the ring, said globe having enlarged or bulbous translucent ends and a transparent or clear intermediate portion connecting said ends, and a shade hav-' ing a downwardly and inwardly projecting portion located around and spaced from the transparent or clear portion of the globe.

GUSTAVE VILLARET.
