TRAFFIC SIGNAL.

Application filed April 1, 1926. Serial No. 99,124.

` ioned so that electrical vconnections and divers other parts will not be broken away when the signal is subjected toy blows or shocks from passing vehicles.

Another Aobject of the invention is to provide a traflic signal stand characterized by means which will cause a flood of light toV be directed tothe roadway.

With the foregoing and other objects in view, the invention resides in the particular construction and arrangement of parts hereinafter described and illustrated in the accompanying drawings.

r1`he nature of the invention and its dis tinguishing features and advantages wi-ll appear when the following specification yis read and connected with the accompanying drawings, in which l Figure 1 is a side elevation, partly in section, of a traiiic signal embodying the present invention;

Figure 2 is a plan view, partly in section, of the top of the signal;

Figure 3 is a horizontal sectional view taken on the line 33 of FigureV 1;

Figure 4 is a sectional view illustrating the lamp casing suspension means.

The illustrated embodiment of the present invention, generally stated, comprises a supporting structure 10, a lamp casing 11, means 12 for loosely suspending the lamp casing 11 from thestructure 10, and means 14 which cushions the lamp casing .11 to restrain the swaying movement which the lamp casing is permitted to have.

rhe supporting structure 10 in the pres ent instance includes a foundation block 15, preferably of cement, which is adapted to be anchored to the roadway in any preferred manner. f

Arranged on the block 15 is a base 16, an the said base is secured to the block 15 by suitable anchoring bolts 17. The base 16 is provided with sockets 18, there being one arranged at each corner of the base 16. In the present instance, the base 16v is hollow, as at 19. Uprights 2O are provided; The uprights are equal in number to the number of sockets 18 with which they are respectively connected, asat 21. Each upright 20 is of tubular construction and its upper end is curved and attached, as at 22, to a socket 23 of a suspension member 24. A cap 25, of any preferred design, is secured in place on the member 24.

Y The means 12 .for loosely suspending the lamp casing 11 includes the suspension member 24, and` also includes the .suspension member 26 which` is arranged in a recess 27 in the member 24, and a suspension member 28 secured, as at 29, to the top of the lamp casing 11. rlhe member 26 is provided with a cavity 30 which conforms to and accommodates the semi-spherical part 31 of the member 28 to allow the lamp casing to sway, The cap 25 is provided with a recess 32; the member 26 is provided with an opening 33 which is extended into the cavity 30, and the mem# ber 24 has an opening 34, all of which permit thesuspension member 28 to have the' desired movement. 1t is to be noted that the member 28 is of hollow construction so as t0 permit lead in wires to be led into the lamp casing 11. In this connection, it is also to be noted vthat one ofthe uprights 20 serves as a conduit which is in communication with a conduit 35 through and by virtue of the recess 19 in the kbase 16 and the passage 36l between the recess 19 and the lower end of the upright. The member 24 is provided with an opening 37, and the member 26 and part 31 are cut away, as at 38 and 39 respectively, to properly accommodate the conduit through which the lead in wires eX tend.

The lamp casing 1l mav be of any preferred construction, is hollow, and is provided with Visors for directin(T the rays of light from the lamps which will be arranged in the casing.

`The means 14 for yieldably placing the lamp casing under constraint, in the present instance, comprises fastening connections 40 and 41` arranged respectively on the uprights 20 and the bottom of the lamp lcasing 11 Springs 42 are arranged between the fastening connections 40 and 41. It will now be appar-ent'that the lamp casing will be allowed to have movement, which will be a swaying movement, and that this movement will be limited bythe springs 42 which serve as cushions. By permitting the lamp casing to have a certain amount of movement, breaking of electrical connections and other divers parts is obviated, and the springs serve to maintain the lamp casing centrally located between the uprights 20. In accordance with another feature of the present invention and dueto the fact that the lamp casing is suspended, it is possible to employ a lamp 43 on the base 16 and a reflector 44 above the lamp to reflect the rays of light emitted from the lamp 43 downwardly on the roadway.

A reflector la may be embodied in the bottom of the lamp casing 11 or may term a separate part and be attached to the bottom ofthe lamp casing. It will, therefore, be apparent that adequate means is provided tor causing a flood of light to be directed to the roadway so that the operators of vehicles will avoid collision with the lower parts of the signal.

Having thus described my invention, I claim:

Lln a traltic signal, a base, uprights on the base, an upper suspension member supported by said uprights, a lamp casing, a substantially semi-spherical member on the top of said lampcasing which is received in a recess in said upper suspension member, connecting members on the nprights respectively and on the bottom of the lamp casing, and springs arranged respectively between i the connecting members on the uprights and the bottom of the lamp casing.

2. ln a tratlic signal, a base, uprights on the basea lamp casing, nieans betwe-en the uprights and the lamp casing suspending the lamp casing to permit the lamp casing to sway, said means comprising a suspension member which is connected to the uprights, a second suspension member arranged within and supported by the irst mentioned suspension member, and a` third suspension member connected to the top of the lamp casing, said third suspension member directly supported by and universally movable with respect to the second suspension member.

3. In a trai'lic signal, a base, uprights on the base, a lamp casing, means between the uprights and the lamp casing suspending` the lamp casing to permit the lamp casing to sway, said-means comprising a" suspension member which is connected tol the upright-s, a second suspension member arranged within and supported by the lirst mentioned suspension member, a third suspensionV member connected to the top of' the lamp casing, said third suspension member directly supported by and universally `movable with respect to the second suspension member, and cushion ing means between` the lamp casing and the` uprights. y c

et. ln a traliic signal, a base, uprights on the base, an electric lamp casing, means between the uprights andthe lamp casing suspending the lamp casing to permit the lamp casing` to sway, said means ycomprising a suspension member which-is connected to the uprights, a second suspension member arrangedwithin and supported by the lirst mentioned suspension member, and a third. suspension member connected to the top of the lamp casing, said third suspension member directly supported by and movable with respect to the vsecond suspension member, said suspension members in correlation adapted to accommodate the conduit for tlie'lead wires oi" the electric lamps within said lamp casing.
