s oleane. j (ci. 24o- 13) This invention relates to portable light xture 1 and-more particularly to a xture which may securely and quickly be attached to a wall or other flat surface and I,connected to a wall receptacle by means of a cord and connection plug.

e It is Yan object of this invention to provide a fixture of this type which is small in size, convenient to be attached, which consumes only a. small amount of current and which is particu-v lal'ly Useful 8S a night light. V,

Itis .another object of this invention to provide a xture of this type which is equipped with a switch substantially of the toggle type close to the light socket; f v. It is a further object of the invention to pro-- vide a xture of the above description with a removable and adjustable shade which may be rotated around lthe lamp therein to throw light in only one direction in the room and shade the 90 room in all other directions. With these and other objects in view theinven- Y tion provides a fixture of simple construction and' few parts, which is easy..to manufacture and which can be sold at a reasonable price. i

Referring te the drawing, la is the cylindrical base portion er Aune fixture shown in Figures 1 and 2 and consists preferably oi' molded phenolic compound. The interior 'f this portion /is shown in Figure 10 and it constitutes ,the housing for a ,snap switch mechanism which is lodged in a deep rectangular recess formed in base I5 bound-v ed by two parallel walls 4| 50 and |5I, rear wall |52 and bottom |53. The front of the rectangle,

, and the bridge portion of |64. Blade |66 will then be moved to the opposite 'end of recess |65 and the bridge piece |64 be driven by spring |61 into the dotted position of'Fig. 10. The large recess in base I5 has an extension |54 at its lower left hand corner as shown in Fig. 10, wherein is located a bent spring |68 which passes through' an aperture |69 in the base I5 to the lower side thereof and is there fastened to the lterminal post |10 which also carries a conductor plug :prong |15 as shown in Fig. 9' or a wire conductor |12 las shown in Fig. 8. r

When switch lever |60 is in the position shown |64. A second terminal post I13 in diagonally op# vel() posite direction to |18 passes through base I5, and carries at its lower end aplug prong |16 as shown in Fig. 9 or a wire conductor I12a as shown in Figs. 8 and 12. 'Ihe base I5 is covered by a cylindrical vcover I8 of which` the lower face is shown in Fig. 11. It is provided with a large rectangular recess I 8| and a smaller rectangular extension recess |82 thereon, which recesses are substantially congruent to the recesses in base I5 when assembled thereon. There is also connected to |8| a second curved extension recess I 83. On

the top surface of cover I 81 is formed coaxially therewith, a hollow cylindrical portion |84 of smaller diameter than the lower part of the cover, and it is provided with an annular groove |85 on' its outside. In the hollow part of |84 a lamp socket |86 preferably of the screw type is mount,- ed. The bottom of socket |86 is formed by an annularring |81. It has an opening I 81a which` connects with an opening |86a-at the lower end of the threaded side wall of socket |86. A washer |88 of hard reproof insulating material covers the inside of the socket bottom and ring I 81. A

metallic conductor |89 which has a head above the top of washer |88 extends insulated through the same and axially through the wall of cover I8 into the recess |8| therein. Conductor |89 carries at its lower end; within recess |8| a contact spring |18 (see Fig. 11) preferably riveted thereto, and this spring is` so bent that its free end forms a contact piece which lies against the top surface of bridge member |64 when the switch is closed by cover I8. On the lower metallic annular rim |81 of socket |86 rests a washer forming part of .Contact spring |88 which extends downward through an aperture in the body of cover I8 into the recess extension |83 so that it contacts with the upper end of terminal post |13. The terminal posts |18 and |13 may have their lower ends connected as shown in Fig. 8 to wire conductors |12 and |12a which lead through a suitable aperture in the sidewall of base I5 to the outside of the fixture; or they may have connection plug prongs |15 and |16 connected thereto as shown in Fig. 9. In both cases the lower openings in base I5 are covered with a suitable circular plate of'insulating material recessed into the lower surface of baseA I5 and provided with a square central aperture. i When the wire conductor connection shown in Fig. 8 is used a soft rubber vacuum cup |56 shown in Figures 1v and 12 is fastened to the bottom of base I5 'by an axial screw |51, with a square shoulder por;

tion lodged in a central aperture in the bottom of base I6 and a head anchored in the rubber of in the base and which are threaded into openings between the bottom in the body oi! top portion I8. When the two parts I5 and I8 are fastened together the upper part of pivot pin I6I is lodged in aperture |6Ia in cover I8 so that bridge member I 64 is guided walls of the recesses in I5 and I8.

On the cylindrical Vtop part |8| on cover I8 is mounted the neck I 9| of a shade I9 shown in Figures 1, 2 and 3. Shade I9 is preferably made of phenolic compound but may be made of metal or other suitable material. Its top portion |92 is part of a hollow sphere; its middle portion |93 is the larger part of an incandescent lamp |95.

yA conical portion |94 joins the shade portion |93 to the neck ISI. 'Ihe interior cylindrical surface of neck I9I ts against the outer surface of the top part |84 of cover I8. In plan the whole shade is limited by its vertical front plane toa circular segment slightly larger than a semicircle. The neckV I9| (see Fig. 4) is rotatably mounted on I|84 by a pair of horizontal ribs |96 which it into recess |85 of cover I8 and extend parallel to each other on opposite sides of neck ISI and perpendicular to the front plane of shade I9 from points near that plane to their intersection with the interior surface of neck portion I9I. 'I'hey permit horizontal rotation of the shade around the lamp axis, but prevent vertical motion. A pair of vertical ribs |91 are formed near and parallel to the front plane of the shade and in front of a diametrical plane parallel to the said front plane they are intersected by ribs I 96 as shown in Figs. 3 and 4. Shade I9 is placed on the top portion |84 of the cover I8'by slipping ribs |96 horizontally into groove I 85. When vertical ribs |91 during that action pass the vertical diametrical plane of I 84, they cause the neck portion ISI of the shade to expand slightly (as shown in dotted lines in Fig. 4) by the resiliency of the material from which the shade is made l of shade I9 to cover I 8 'is shown. In this construction ribs I 96 and |91 are omitted but an arcuate band ,spring |98 of the width of groove |85 is fastened by a rivet or similar means |98 to the rear wall oflIIlI. This spring is open at its front and its two/ends are bent outward so as to form.

the equivalent of the two vertical ribs |91 while the spring itself forms the equivalent for horizontal ribs |96 as means to hold the shade fastened' to and-yet rotatable onthe xture. This construction is preferably applied when the shade is made of non-resilient material.

From the foregoing it will be seen that the present invention provides a novel fixture which is useful in many ways particularly as it may be made either for quick attachment to any place of a wall by means of the vacuum cup thereon and a plug connection to a convenient wall receptacle outlet, or it may itself be provided with prongs to fit into such receptacle outlet. In either form the rotatable -shade thereon may be used to shield certain parts oi a room where no light is desired and to illuminate others. For this reason, this device is particularly suitable as a night light, especially because the snap switch connected therewith permits a person to turn on the light by lthe switch thereon without groping in the dark to find a wall receptacle and thento nd the aperture therein for insertion of the plug. The mechanical construction of the device is of the utmost simplicity and so compact that its center of gravity is brought close to its supporting 'surf ace and the device is easily assembled and taken apart by the insertion or removal of only two screws 200. 'I'he lamp used in this device consumes, only 5 watts of 'current and is therefore very economical.

While this device has been illustrated in different forms it is adaptable to many modications in its details of construction in view of which it is to be understood that the claims are to be construed and the invention is to be limited only by the scope of the claims and notyby the illustrated embodiments.V
