Application July 25, 1946.- Serial No. 686 ,0 79? This invention relates generally to lighting fixtures.. More particularly our invention is directed to animproved construction for reading lampsof the type adapted for use in reading. inbed.
. Bed reading lamps as heretofore constructed have long been a recognized source of annoyance and conflict, in cases where two persons occupied the same bed. while the other desired to sleep, the light rays from the lampwould annoythe sleeper. It is therefore one of theprincipal objects of our invention to provide a bed reading lamp of the character described which shall be so constructed and arranged as to avoid the above described disadvantages inherent in prior constructions of bed reading lamps and which at the same time shall be novel, simple in constructionand highly efficient in use. i
Another object of our invention is to provide a novel bed reading. lamp which shall represent a-general advance in the art.
Other objects of our invention will hereinafter be pointed out or will become apparent from the description to follow. i
In the accompanying drawings,
Fig; lis a perspective View of abed reading lamp constructed and arranged in accordancecomprising a casing H], which may be'of metallic or other suitable opaque material. The said casing Hlmay be rectangular in shape; as shown, and composedof a topwall l I', end walls i2 and l4,-
a front wall I5 and a rear wall It; and open at the bottom. The saidtop, end, front and rear walls of the' casing may be integrally joined, as shown, to render the joints light-proof, so as to normally permifithe light rays from within the casing to escape only through the bottom opening.
Mounted'within the casing l0, and fixed to the end wall I2 thereof is an electric-"'lampsocket S of any wellknown standardtype, adapted to receive therein a suitable lamp L. The said socket S may be retained in place by a -threaded bushing:
ill threadedly engaged in the base IQ of the socket and passing through anopening12l in thewall l2. A nut member 22 on the bushing '20 will lock the socket against the saidwall l2.
It is noted that the lamp L extends inwardly of the casing. in a longitudinal direction away When one person wished to read 5 Claims (crew-4 from-the wall i l-2 ,.-;to a poi-nt-beyond-the center of; said casing:- Aeuitable wire -2 3-; flconnected-to the socket s andpassingthrough-the bushing. 20 to:- the outside-of; thecasingieads toa suitablesource:

The light shield: 30 is of such size that the inner transverse edge 33a thereof will contactively em: gage the innersurface of i the wall -,|'4- of thercasing at -its free edge.

Assuming. that a' situation occurs where the personwdesignatedby-Fthe letter A in Fig-sl de noted. that nonezof the lightrays emanating-from:

It=is noted thatthelocationof the'pivots td and: 35: are critically:- arranged :so thatzwhen the. lightshield 30 is pivotally moved to the position 30 as just described, the corner 33b will abut the socket S at a point beyondthe inner extremity ofthe lamp L so as to provide against light passing to the sleeping person A.
Should the occasion arise when both persons A and B desire to read at the same time, the location of the pivots 34 and 35 are such that the light shield 30 may be pivotally moved in a clockwise direction to the dotted line position indicated by the numeral 30" within the casing. In this last named position, it is noted that the light shield 30 will be entirely hidden from view and this is the position which may be employed when the bed reading lamp is not in effective use, so as to present the appearance of the usual bed lamp.
In accordance with our invention, as above described the light shield 30 is preferably mounted on the casing It in such a manner that there will be frictional contact therebetween whereby the said light shield will be maintained in any desired angularly rotated position about the pivots 34 and 35. One such means of frictional mounting is shown in the drawings and illustrated in detail in Fig. 5 thereof. As noted, the pivots 34 and 35 may be made in the form of screw members with the heads 34a and 35a thereof contactively engaging the outer surfaces of the casing walls I5 and I5 respectively. A nut 38 threadedly received on the pivot 34 contactively engages the inner surface of the light shield wall 3|, while a nut 39 threadedly received on the pivot 35 contactively engages the inner surface of the light shield wall 32.-Between the said walls 15 and 3| and between the said walls It and 32 are interposed resilient members 40 surrounding the pivots 34 and 35. The amount of resilient friction desired may be adjusted by the pivots and nuts 34, 35 and 38, 39.
For convenience in removably attaching the bed reading lamp of our invention to the headboard of a bed we provide the following construction:
Mounted on the wall I 4 of the casing I in axial alignment with the bushing 20 is a shaft member 42 having a threaded outwardly extending portion. Rotatably mounted on the shaft 42 and bushing 20 is a bail member 45 comprising the side arms 43 and interconnectingcross bar 44. Permanently attached to the cross bar 44 are a pair of resilient hooks 48 adapted to snap over the top edge of the headboard 50 of the bed as clearly shown in Figs. 1 and 2 of the drawings. A nut 46 on the member 42 acting in cooperation with the nut 22 on the bushing 20 serve to frictionally hold the bail member 45 in any desired angular position.
In accordance with the provisions of the patent statutes, we have herein described the principle and operation of our invention, together with the construction which we now consider to represent the best embodiment thereof, but we desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combinations and relations described, some of these may be altered and other omitted without interfering with the more general results outlined, and the invention extends to such use.
