T0 all whom it may concern Be it known that I, WiLLiAM H. SPnNCnn, s citizen of the United States, and e resi dent of the borough ot Manhattan, city,

county, and State of New York, have invented certain neu7 and useful Improvements in llluminetedSigns, of which the following isnJ full ond clear specification.

Referring more particularly to the drewings this invention rel-etes to illuminated signs, in which a. source oi light disposed WithinA e. suitable housing is employed to illuminate sign-bearing surfaces constitutinn' the Walls of said housing.

The primary object of my invention is to provide en, improved construct-ion and arrangement of parte in un illuminated sign ot this ,character according to 'whieli the intei-lor of the sign is more readily cleaned sind the lights renewed.

T he preferred embodiments of my invention are shown on the drawings, in which,

Figure 1 is a. side elevation ot one einbodinient; Fig. 2 is :in end-elevation of the seine; Fig. 3 is :i transverse section of the seine.

The embodiment shown in Figs. 1, 2 and 3 includes a housing,r comprising' s hood 1, within Which is mounted the light source 2 (preferably an incandescent light), walls constituted by oppositely und 4,'which serve to mount the translucent plates 5 and (i, which are adapted to be provided With 'any suitable characters to be displayed, such es those comprising the word Eiit, shown in Fig. 1. Frames 3 :iiid 4. :ire hinged' to the hood 1, preferably being pivote/d on the pins 7 und S arranged :it oppositeends of the hood 1. By this ineens, said frames are adapted to swing into/"the positions shown in dotted lines in Fig". z, th'us'perinitting of any access to the interior of the housing for the purpose of renewing the lnnips or for cleaning the inner ol the plates and il sziid plates are preferably provided with iciiccting inner surfaces. As shown. best in. dotted lines in Fig. 2, each o? the frames 3 find 4 are provided with Wedirsheped flanges 9 and 10 at each end which overlap when seid iframes are in closed position to forno u. closed housing for the sign. A hook 11, which is pivoted at 12 on one of the iong'es 9 et each end, is adapted to engage en eye let 3.3 carried by the flange 10 on the oppodisposed 'frames 3 sitely disposed freine 4. When in closed position, the inner surface of ythe translucent plates 5 ond 6 are arranged at a suit-v able angle to each other and in suitable relation to the light source 2, to cause the light rays from the light source 2 to be re- -ile'cted frointhe inner surface of each of seid plates 5 and Gon to the reflecting surM fece opposite thereto. ln this manner, the light emanating from the light source 2 is vmade to traverse the plates 5 and 6 by being reflected back and toi-th between them, thus ocensioning a uniform illumination throughout the extent ol both oilsoid plates. This linnkcs thc display characters plainly visible to anyone within sight of the sign. If desired. the inner surface of the plates 5 and l may be provided with any suitable Cootingr4 over :my portions of seidsurioce, so as nil Without enteringr into detail of the Veri-v ous modifications that con'be made in the construction :mil arrangement of parts with in the principle of my invention, What claim isi 1. In an illuminated sign, e light source, o housing for said light source comprising o hood `within which seidv light source is mounted. sind oppositely alisi.' ed side Wells liiiiged to seid hood and converging to s, common line, said side Wells being provided with overlapping `flanges for closing the ends of said housing.

2. In :in illuminated sign s light source, :i hood therefor, side Wells hinged to seid hood :md depending therefrom, seid side' walls being adapted tc have their lower edges brought together end translucent plates constituting portions of seid side wells, seid pistes being provided with cherzictcrs to be displayed, seid side Wells being .provided with end fflanges adapted to overlap .ind form a closed housing` when seid side walls are in contact along their lower edges.

3. 1n fen illuminated sign, an inverted trough-shaped hood, e light source Within seid hood, a signbeering panel swingingly suspended from said hood on one side of said light source and constituting one wall of said sign, said sign being provided with W iti-1 overlapping Hanges `for Closing the another Wall extending downwardly from ends of said sign.

said hood on the opposite side of said light source, and means for releasably securing the lower edges of said oppositely disposed Walls together, said Walls being provided WILLiAM H. SPENCER. Witnesses
