Specification of Letters Patent.

latentei Apr. 2", 1.97339.

Application filed July 18, 1919. Serial No. llf.

le it known that I, FLoifn A. Roo'r, a Citizen. of the United States, residing at liioelqiort, in the` county ol' Niagara. and Siate oi. New York, have inventefl new and nseinl improvements in iidvertising'igns. of wink-li the i'ollmvinggr is a speuili 'at-ion.

invention relates more particularly to =:\lertrir advertising' signs of the kind l: pied to he erected. on buildings or other e ations line oi. itis objects is to improve the Conffii'rniftien of the signi with a view oi. render ing; it strong' and rigiil. rellnring its cost enabling it to he r )ailily constructed nient@m im-.ordinii to the varying quireif li rent. localities or ronilitions.

dividually preferably by an incandescent electric lamp iti arranged centrally in rear thereof and inclosed by a case or housing; 2S carried by the correspoinlingij panel-tame. This case may he constructed ot sheet metal and is closed on all sides7 except its .lront side where it is provided Awith a projecting marginal flange 2l() seatedaeainst the inner or rear liange ot the panel-frame. which flange arranged lengthwise ot' the sijzn and to which it is riveted or otherwise secured. ln its preti-irreal l'orin, the back lll of each lamp-case is concavo-convex throughout its length in a horizontal direction. and its inner sui-tace is coated with a suitable .lightretlecting material. such as white enamel to r'etlect the light against the back ol the signrl`o etl'eetually Ailluniinate the extreme ernls ot the sign-panel as well as its intermediate parts, an auxiliary pris-matic reflector 32 may be employed in each lampcasing. rlhis prism is arranged vertically with its apex facing the sign-panel and cxtonds trom top tobottom of the lamp-case, so that the rearward rays ot the lamp are reliected by the sides ot the prism upon the end portions ol' the sign-panel. The prism provide(L with an aperture ior receiving the neck ot' the bulb.

it desired? a circular concavereflector ll may be placed over the 'liront ot the lamp bulb to rel'lect its torward rays rearwardly against the main rotlector or surlace ol the lamp case. This auxiliary reflector has supporting arms or holders` ll which embrace the bulb.

lily this arrainnfment ot rel'lerlors7 the light is ditlused over all parts ot the signpanch which is thus unil'orinly illuminated from top to bottom and trom end to end.

ln practice, the central topmost signpanel is i.,.itenc.lcd to be illuminated continuously during; the nip'ht-nse olE the sigla while the. remaining signs are intein led to be flashed or illinninated interniittraitly,' Any suitable controllinpv mechanism may be employed lor this purpose. lThis forms no part ot my invention and it is ther-clore not illustrated.

horizontal shade lll is preferably 'ar- 'angied to project forwardly 'troni t ie lower edge ot said central top-panel to avoid illuniination ol the remaining` sign-panels, eX- cept when illuminated by their own lamps.

The concavo-conVex back ot the lainpcase7 in addition to serving;` as a rel'lector, also materially stillens the case.

lt will be noted that the panel-trames ll) in addition to carrying; they sign-panels. also act as tie-mcn'1bers`for connectingv and stillieningithe adjacentuprights ot the main trame. thus simplifyingy the structure and at the saine time producing, a trame olE the necessary strength and rigidity to withstand high wind pressures. This constructirm` also enables the 'size ot the sign to be readily increased or reduced by employingl a greater or less number o'lI vertical rows ot panels.

l claim as my invention:

l. Ain advertising sign, comprising,` spaced uprights, tic-members ol' inverted U-torin arranged between adjacent uprights and connectingtheir lower portions, and panel.- trames. carrying advertising panels and ecnnectingsaid uprights above said tic-menihers.

2, An advertising sie-n7 comprising spaced uprights, panel-trames carrying: advertisinfb` panels and arranged in horizontal ro\vs each panel frame' being fitted between a pairv ol iipi'iglits, the j )anel-iiran'ies in adjacent horizontal rows being spaced apart, and tie-bars arranged in the spaces between said rows and connecting;` the adjacent paneltrames An advert'isinte` sign7 comprising spaced nprights, angle-iron panel-iframes' carrying advertising panels and fitted between said uprights, the liront flanges ot said paneltrames being` substantially l'lush. with those olE the uprights and narrower than the 'nprights, and brace-members secured. to 'the rear portion ot said uprights.

fl. Inl an advertising,` sign, the combination ot a panel-traine7 an advertising,- panel arranged in said trame7 an open-.laced lamp case applied to the rear side of' said panelliran'ie and having` a concave back provided with aniinternal reliecting surface7 an npright reflect-ing prism located centrally on said reflecting surface, and a lamp arranged in said case in 'front/ot' said prism.
