This-invention relates to traffic control systems,
and relates more particularly to improvedfm'eansfor controlling pedestrian traflio and forecoordihating such trafiic with vehicular .trafiic.
An important object-oi ithe'present vinventionu's to provide a novel pedestrian traffic control unit which is mounted in flush relation within .the sidewalk curbs at street intersections, and "which is provided with Stop and 'Go' illuminated signs which are coordinated with the conven tiona'l automobile trafiic lights and preferably are connected in the same circut as the latter.
The signal device of the present invention is a self-contained structure comprising an outer" housing open on one Sula-preferably atwthertop, to receive an inner housingcontainingthe'illumi nated signs and other operative parts :including. the usual transformer for the neon tubes. The
inner housing is a sealed unit which is locked:
within the housing by 'novel means, Lth'e upper wall of such inner housing preferably :being formed of transparent plastic material through,
which the signs .are visible, 2. substantiallys'fmilar wall and signs being provided :on. th'e iront of such inner housing. Thus,.=a:pedestrian/standing on'the curb has two visible signs .tmguidehim, one of which is horizontally .d sposed'whichihe' sees by looking downwardly, andlthexotherpvertically disposed and located directlyzacross :the street whichhe is about to travel:over.
The device of" the present invention also lends itself to a particularly novel advertising arrange.- ment.
Another object of "the"presentiinventioniiis 'to provide mproved pedestrian trafilc control means which will greatly reduce the accident toll at street intersections since'the elements .of chance and confusion are definitely eliminated. Vehicular trafiic lights must of necessity be placed in a position most suitable to the motorist, and-in most instances this position is. most' unsuited::to the needs of the person on foot. The structure of the present invention will provide every inducement to keep the person on. the sidewalk until the light changes, will impress the pedestr'an with his part in traflic safety, and is a definite aid to near-sighted orcolor-blindpedestrians. Moreover, it will speedup car trafiic'and reduce the need for the policing of intersections.
By mounting the complete unit inrecessedrelation w thin the curb there is no obstruction to normal pedestriantravel. Also, it illuminates the :curb at night and hence reduces pedestrian 'in uries.

An embodiment (of the invention includes an inner housing I 0 and ran outerhousing H The inner housing is formed with-a lower wall 12, end walls t3 and 14,:front an'd'rear sidewalls l 5 and LliB, respectively, and an upper wall "20 of slightly larger dimensions than the lower wall; thus providing afflange I 9 extendingaround'such upperwall. walls-'lii and 20=are desirably'formed from clear,"itransparent orwtranslucent plastic material; anditheremaining walls may' be: opaque and ibeforme'd-tof. metal, plastic, or other suitable material. A'suitable electrical plugLZl mounted inx'en'd wall l.5, and the-inner'ih'ousing mayotherwise beatsealed unit.
Within the housing are one or more transformers 22 and a plurality 'ofsuperimposed neon tubes spelling "out the words 'of warning, etc. In the arrangement :-shown,t-there vis tuloe-dn for the word Go.-and tube 2'4.--for"the Word' Stop?, both. horizontally disposed and visible when lighted, .as indicated in. Figs. .1. and through .There is. further tube 2.5. for the. word Walk andlt'ube r2t for the word "Wait. The letters 'W .and A may becomwhen lightedythroug'h upper'hori'zontal wall12'0. A suitable circuit (not shown) is arranged to alternatelylight the Go and Walk tubesand' theStop' and Wait tubes. As'was'earlier pointed out, this systemmay b'e'operated by the same timing mechanism as is 'employedfontlre stop and Go-automobile traffic lights.
For the purpose of separating the front vertical ':tubes' 23 and 24 from the upper hcrizontal tuhesazt sand 226,:antang1i1arbaifie platecIElg'.
These tubes are visible,
is employed, such plate having a base portion 30, horizontal portions 3| and 32, and vertical portions 33 and 34. Such bafile plate effectively shields the tubes in one area from those in the second area. In addition to the foregoing tubes, there are horizontal tubes 35 which are arranged to be continuously illuminated when the device is in operation for illuminating the advertising signs.
The outer housing comprises a lower wall 39, an end wall 40, a front wall 4| having openings 42 and 43 therein, a rear wall 44 and an opposite end wall 45. There is further provided an extension 46 associated with end wall 45. The outer housing is arranged to be permanently mounted within an opening 50 within the curb I. A recess 62 extends around the three sides of the opening adjacent the upper surface 63 of the curb. The
front wall 4| of the outer housing is substantially flush with the vertical'wall 5| of the curb and recess 52 is of such size as to receive upper transparent or translucent wall 20 of the inner housing, the flanges l9 extending around three sides of such upper wall being disposed withi'n'such recesses.
For the purpose of locking the inner housing within the outer housing, end wall H! of the former is provided with a key 56 which is received within an opening 51 in end wall 40 of the outer housing. After the inner housing is mounted in place within the outer housing it is locked at its opposite end by means of locking plate 60 shown in detail in Fig.2. This locking plate is provided on its lower surface with a circular operating disc 6| which is arranged to be rotated by means of a screw 62 extending to the upper surface of such plate.
Locking bolts 64 are pivotally secured at, their inner ends, as shown at 65, around the periphery of disc 6|. slide, confine movement of the outer terminals of these bolts to substantially straight-line reciprocating movement. End wall l3 of the inner housing is provided with an opening for one of such bolts, and there are further provided similar openings 12 in the extension 46 of the outer housing. Thus, after the inner housing is in place within the outer housing with key 56 inserted within opening 51, locking plate 60 is inserted in place and the bolts 64 are actuated to move outwardly into their respective openings. End wall 46 of the extension of the outer housing is provided with an opening 13 through which the electrical cable (not shown) may pass to plug 2|.
: It was earlier pointed out that the inner housing is provided with horizontal tubes 35 for illuminating the advertising signs. These signs are shown in Figs. 5 and 6, and may comprise a plate of opaque plastic material having formed therein letters 16 of translucent or somewhat transparent plastic material. Thus, the neon tubes behind such plate illuminate the trans, lucent letters. Plate 15 may be mounted within opening 43by means of angle brackets 71 secured, as by means of pin 18, to such plate. These angle brackets have rearward extensions which are disposed behind side wall 4|. The traffic control device of the present invention lends itself to novel advertising arrangements in that the words Stop and Go may be followed by the word For which in turn is followed by some well known trade-mark. Thus, in the arrangement shown in the drawing the letters 16 on plate 15 Guides 61, within which the bolts 4' spell out the words "For Clix," which is offered by way of illustration only.
While one form or embodiment of the invention has been shown and described herein for illustrative purposes, and the construction and arrangement incidental to a specific application thereof have been disclosed and discussed in detail, it is to be understood that the invention is limited neither to the mere details or relative arrangement of parts, nor to its specific embodiment shown herein, but that extensive deviations from the illustrated form or embodiment of the invention may be made without departing from the principles thereof.
