I TRAFFIC SIGNAL.

Application filed ()etober 28. 1924. Serial No. 746,399.

My present invention relates to devices for warning and controlling vehicular traffic on streets and highways and it has for its object to provide a simple, inexpensive and practical sign or signal of this character that can be conveniently shipped and easily installed and which will be particularly, though not exclusively adapted for use at street or road intersections to direct tratlic and pedestrians by day and by night for the mutual benefit and safety of all concerned. My improvements are further directed in part toward rendering the signal sutliciently imposing to claim the respect of persons otherwise careless of collisions but without impairingits simplicity of construction or the facility with which it may be cleaned, repaired or inspected. To these and other ends the invention resides in certain improve ments and combinations of parts all as will be hereinafter described, the novel features being pointed out in the claims at the end of the specification.

Similar reference numerals throughout the several views indicate the same parts.

In a general way, a preferred embodiment of my invention includes a tower like structure adapted to be erected at a street intersection or in the center of a street or road. At the top are beacon or danger lights of high visibility while the sides are utilized for the display of instructional signs. The lighting arrangements are such that the various lamps are well protected yet the signs mentioned are t ooded with light. The tower though itself lightly built, rests on a heavy base well calculated to resist ordinary impacts from colliding wheels. As supplied by the manufacturer the base is in the form of a knock down sheet metal shell. This is placed in the desired position and then filled with concrete to give it the desired form, weight and stability, all of which may be accomplished by relatively unskilled persons.

In the present embodiment of my improved tratlic signal I employ a base 10 including a casing containing a filler of cement 11 which forms a relatively heavy support for the lamp post 12, and the signal box or housing thereon indicated generally at 13 in Figures 1 and 2. The base is preferably diamond shaped and is disposed in the middle of the street or highway, as indicated in Figure 14, and is of su'tlicient'weight to prevent it from being overturned and wrecked should it be accidentally struck by a passing vehicle.

The casing is first deposited at the point desired for the location of the signal and is then filled with cement, which is preferably built up in the center to a point slightly higher'than' the sides of the casing to form a fiat portion for the reception of the lamp post from which portion the cement is taperedoff as indicated in Figure 3. The casing forms a permanent wall around the cement andmay be painted any desired color. It pe mitsct the use of relatively cheap cement or concrete material, since only a small portion of the cement is exposed to view, this portion being of a higher grade material if desired.

The construction of the casing isbest shown in Figure 7 and preferably embodies a knock down type of easing whichcomprises four main similarly shaped sections 14 connected by two central sections 15 and two end sections 16, all being preferably constructed of sheet metal and having flanged edges adapted to interlock as indicated at 17, in a manner to form a smooth exterior surface for all parts of the casing. The opposite sections 14 are tied together by means of removable cross rods 18 having downwardly bent ends 19 engaging in suit able openings provided in the angle bars 20, which are preferably secured to the sheet metal sections by spot Welding. This construction may be very quickly assembled without the use of special tools, merely by sliding one section upon the other.

The knock down metal casing affords a .very considerable saving in the cost of producing the present signals, by reason of the fact that it avoids the expense of the usual temporary forms required in cement struc tures of this kind, such forms being necessarily a big item in the cost of production,

particularly where the work is carried on at a number of d1fferent points scattered overrelatlvely Wide areas, as in the present Case.

with a separate circuit, preferably of a greater voltage, such as a power supplying circuit or a street lamp circuit. By having separate lamps for illuminating the signals, connected with separate sources of current, one lamp or set of lamps can be depended upon to illuminate the signals should the current for the other lamp be interrupted.

The lamp post 12 is preferably hexagonal in cross section with the side plates 25 thereof tapering slightly toward the top to afford an attractive design as indicated in Figures 1 and 2. The means for connecting the side plates is best shown in Figure and coinprises similarly shaped metal str ps 26 pref erably spot welded to the inner faces of the side plates at opposite s des of their meeting edges, and provided with ad acently disposed bent flanges 27. A retaining strip 28 has its edges 29 bent inwardly to engage behind the flanges 27 in a manner to firmly connect the several plates 25 one with the other. The side plates may be quickly assembled or disconnected by a sliding movement of the retaining strip 28 into or out of position as desired, said strips being preferably extended substantially the full length of the sides as indicated in Figure 3. This knock down construction facilitates storing and shipping of the parts and also renders it inexpensive to assemble and disconnect when desired.

The post is secured to the cement base by means of bolts 30 anchored in the latter and extending upwardly through the horizontal flange of a base plate 31 having a vertically disposed flange 32 shaped to conform to the interior surface of the post and connected therewith by screws or bolts 33 as shown in Figure 3. The screws are'prefen ably extended through the flange 32 and each threaded into a reinforcing plate 34 as indicated in Figures 3 and 6, the reinforcing plates being preferably spot welded upon the flange 32.

The upper ends of the side plates 25 are connected by a ring shaped member 35 secured to the side plates by bolts 36 and having an inwardly turned flange 37, to the underside of which are preferably spot welded the endsof a depending bracket or yoke 38 for supporting the lamp 24 as shown in Figure 3.

The housing or lamp box indicated gem orally at 13 comprises preferably a main body portion 39 and a lower flared or skirt portion 40, the latterhaving an upstanding flange 41 disposed inwardly of the portion 39 and secured thereto in any desired manner. The body and skirt portions of the housing are both preferably made hexagonal in shape to conform to the shape of the lamp post. The body portion is pro vided with a suitable cover 42 hinged thereon at 43, the cover being hexagonal at its base and tapering to a point at its top as shownin Figures 3 and 4. The base of the cover is slightly larger than the housing 39 to afford a ventilating space between the two, as indicated at 44.

The sides of the housing 39 are provided with openings, in each of which is disposed alens 45secured by suitable clips 46, as shown in Figure 3. The lenses maybe of any desired shape and color and are adapted to be illuminated by the lamp 23 but will also be illuminated by the lamp 24 should} the light 23 become extinguished.

The flared or skirt portion 40 of the housing is provided with a plurality of mirrors or othersuitable reflectors as indicated at 47 in Figures 3 and 5, which are adapted to reflect light from the'lamp 24 downwardly I along the sides of the lamp post to illuminate the same in order to display by night such traflic signals or legends as may be deemed advisable to paint or otherwise dispose upon the post for the guidance, control, or direction of the vehicular tratlic and the pedestrians passing the signal from time to time.

Should the lower light fl t become extinguished the upper light :23, on a separate circuit, will be sufficient to both illuminate the signals 45 and to provide the mirrors or reflectors l7 withsulficient light to afford the necessary illuminationfor the sides of the post.

The mirrors 4:? are supported at their lower sides by the channel shaped portions 48 held in the desired position upon the lamp post by the upwardly extending arms or standards 52 having their lower ends resting upon and suitably connected with the flange 37 of the ring shaped member 35 as shown in Figure 3. The upper ends of the arms are suitably connected with the inner face ofthe housing 89 while the intermediate portions of the arms are offset inwardly to clear the upper ends of the mirrors as shown in Figure 3. v

The lamp 23 is carried on a bracket 53 removably supported upon the upper edge of the housing 39, thus. permitting access to the lower lamp 24.

In certain locations of the signal, particularly at street crossings which are poorly lighted, I provide a suitable lens at each of the two sides of the signal nearest the curb or edges of the road, which are so designed and positioned upon the housing as to direct rays of light from the source of light therein upon the cross walks 54, as indicated by the dot and dash lines 55, extending from a signal 56 constructed in accordance with the present invention and preferably disposed in the center of the highway or between the sidewalks 57 as shown in Figure 14. The present signal is therefore adapted toboth serve as a beacon for vehicular traffic at night and to illuminate the side walks at the point of crossing as well as to constitute a directing signal by day.

In a signal constructed in accordance with my invention, the knock-down'parts, before being set up, can be packed; or assembled in a relatively, small space and shipped or transferred to their destination at comparatively little expense.
