should proceed. This case is a continuation in part of application Serial No. 4,669, filed January 26, 1925. v
The eneral object of the invention is to provide an effective sign having the accordingly, which the driver cannot fail to see, yet will not obstruct movement of vehicles over the street, road or pavement in any way, the sign to be capable of yielding in all directions under the load of a vehicle yield under the weight of the vehicle which may happen to ass thereover, no matter from what direction the sign happens to be engaged and to resume its normal position after the vehicle passes thereover.
A further object of the invention is to pro-- vide an effective means for mounting such signs in roads or pavements.
A further object is to provide means for mounting the sign from which the sign may be 'readily removed for replacement when worn out. or broken and, in addition, to provide a sign so formed as to permit of readymounting or removal from said means. i v The foregoing and obtained by the trafiic sign construction illustrated in the accompanying drawnings and described below. It is to be understood that the invention is not limited to the specific form thereof shown and described.
Of the accompanying drawings,
Fi re 1 is a front elevation of a sign embodying the invention shown mounted in a pavement; I r
Figure 2 is a plan thereof;
Figure 3 is a perspective viewof the sign per Se; l
Figure 4 is a section on line 4-4 of Figure ,1; and
Figure 5 illustrates the action of the sign under the load of a vehicle.
other 7 objects are 1 Referring to the drawings, the numeral 10 designates a sign of highly flexible, resilient, weather-proof material such as vulcanized rubber compounded to be of a toughness corresponding to that employed in tire treads and vulcanized either with or without, textile or other reinforcements therein. The sign 10 preferably is a comparatively thin sheet of rubber 11 of any suitable shape and, to facilitate replaceable mounting thereof, may have a ledge of rubber 12 integrally formed on its lower A legend for imparting any desired warning is provided on .the upperportion of sheet 11 as at 13 in any'suitable manner. The sign is thus adaptedto be embedded to a substantial depth in a pavement with the portion carrying the warning legend normally projecting upwardly therefrom.
The preferred type of mountin for the sign comprise a box-like frame 0% material, such as wood, metal plates, etc., including front and back members 14 and-15 and end members 16 and 17 adapted to be embedded in concrete, asphalt or other plastic medium capable of hardening to secure the frame in the pavement. A portion of a completed pavement can beremoved for embedding the sign therein or it may be embedded therein during construction of the pavement.
The front and back members 14 and 15 of the frame are spaced apart approximately the thickness of the sheet 11 plus the width of ledge 12, the ends 16 and 17 preferably just clearing the ends of the sign and the depth of the frame being approximately one-half the height of the s1 10. The frame accordingly defines an e ongated slot 18 in the avement into which sign 10 may be inserted. Totretain the sign 10 removably in place a clamping bar 19 is employed of a len h adapted to fit between the ends "16 and 1 ofthe frame ,with space indicated at 20 for the'insertionof a tool to engage the end of the bar to remove it, the bar being of a thickness somewhat greater than suitable when it is flexed. To mount a sign 10 in place, the lower ed is inserted in slot 18 until it rests upon t e bottom thereof. The bar 19 is then forced downwardly into the slot 18 in front of'the si n onto the ledge 12, compression of the rubber of the sheet 1L serving to hold the sign in place. To remove a sign, clamping bar 19 may be first pried out of the slot by inserting a tool across an end of the frame into the space 20 against one end of the clamping bar. The sign 10 can then be lifted out of the slot.
In use the sign is directly in the path of vehicles passing along the roadway where a driver cannot fail to see it. If a driver should happen to guide one of his wheels over the 51 it will flex downwardly easily without oie ring suflicient resistance or obstruction to the travel of the vehicle to be ap reciable to the driver or to result in ac- O1 ents fromjskiddin or other causes. Due to the resilience of the sign it will immediately spring upwardly to its normal position after the load is removed therefrom. It will flex under the load of a vehicle no matter what the angle of approach may be and it will not injure vehicle tires in any way.
Modifications of the invention maybe resorted to without departing from the spirit thereof or the sco e of the appended claims.
