TRAFFIC SIGNAL AND SKIGNBOARD.

/ Appiication med Mami 2o, 1.924. serial No. 700,694.

To all whom it may concern:

Be it known that I, ANDREW B. CAHDEN,

a citizen of the United States, residing atv Durant, in the county of Bryan and State of Oklahoma, have invented certain new and useful Improvements in Traiiic Signals and Signboards, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to traffic signals or direction signs, and a particular object of the invention is to provide a structure of this character which is particularly adapted for use in villages, towns and cities for the purpose of indicating street intersections and acting as a sign post for the streets leading therefrom.

A further object is to provide a device of this character which is also adapted to be used as a sign display7 device and which is adapted to support a number of signs in such manner that they will be particularly attractive and will be constantly changing.

A further object has to do with the details of construction and arrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is an elevation of a traffic signal and sign board constructed in accordance with my invention, the base being partly broken away and the supports for the indi vidual sign boards being in section;

Figure 2 is a sectional view on the line 2-2 of Figure 1;

Referring to these drawings, 10 designates a mast or like member, preferably of iron or steel pipe, which may be of any desired height as, for instance, seven feet, this mast at its upper end being so formed as to support a lamp globe 11 carrying a lamp 12. The lower end of the tubular pipe which constitutes the mast or post is supported in a block 14 of concrete, this block preferably having the form of a truncated pyramid so as to provide a number of upwardly and outwardly inclined faces 15 f upon which traflic directions may be placed as, for instance, directions with regard to the speed limit or the distance and direction of a cer tain other town or village.

Mounted upon the upper end of the post are four arrows 16 or any desired number may be used pointing in the direction of the four intersecting streets and containing the naines of the streets or other highway directions. AJ ust below these four arrows are four larger sign boards 17 which are disposed at right angles to each other and which preferably terminate in pointing hands, these sign boards having thereon traiic directions as, for instance, directions as to the speed limit or directions to keep to the right, left, etc. The posts or masts being hollow permit an electric wire 18 to pass up through the mast or post or the wire may be taken from an overhead feed wire and brought down through an opening 19 in the upper end of the mast or post. The base 15 which, as before remarked, is of concrete, f

may be held firmly down at any desired position by metal strips 20 which are set into the concrete and project beyond the same and have pins or screws 21 which may be driven down into the earth or other material of the roadway.

Rotatably supported upon the mast or post 10 is an elongated sleeve 22.y This sleeve at its lower end is supported upon ball bearings 23, while the upper end of the sleeve is supported in ball bearings 24. Mounted upon the sleeve 22 to rotate therewith are a plurality of upper and lower sets of radial arms 25, each pair of these arms supporting vertical shafts 26, the shafts being free to rotate in the arms and the lower end of each shaft being supported in a cone bearing or equivalent member 27 carried by each lower arm.

Mounted upon the shafts 26 are the rotatable signs 18. These sign boards 28 are preferably two in number for each shaft, the edges of the sign boards being brought together and connected, as illustrated in Figure 2. The various signs may be painted or otherwise applied to these sign boards,

and it will be obvious that if there is any f base, ay stationary supporting shaft rising from the base, ya sleeve rotatable'upon seid.

shaft, upper `and lower end thrust bearings for said sleeve, upper and .lower spiders carried by said sleeve and rotatable therewith, braces connected with elements ofthe lower thrust bearing and with the lower spider, the upper spider including arms -formed with holes and the lower spider including arms formed with sockets, and sign plates having upper and lower trunnions engaged within saidholes kand sockets respectively,

theupper` edges ofthe sign plates terminat-l ing considerably below the upper spider whereby the sign plates may be moved upi `wardly toeffectdisengageinont of the lower trunnious from the sockets andinay then be subsequently moved downwardly to disengage the vupper trunnions from within said holes.

In testimony whereof I hereunto aix my 20 signature.
