2 Claims. (Cl. 25613.1)

This invention is an improved traic guard particularly intended for roads or streets carry'- ing fast moving traflic.

One of the objects is to prevent a vehicle from traveling into dangerous territory, this to be effec'ted without unduly damaging the vehicle or causing injury to its occupants. Other objects may be inferred.

' Referring to the accompanying drawings:

Figure 1 is a side elevation of the new traffic guard.

Figure 2 is a top plan. Figures 3 and 4 are side and end elevations, respectively, of details shown by the right-hand portion of Figures l and 2.

Figures 5 and 6 are top and side elevations, respectively, of details shown by the left-hand.,

end portion of Figures 1 and 2, Figure 5 being partially cross-sectional and taken from the line V-V of the latter figure.

Figures 7 through 10 are cross-sections of modifcations of the invention.

Figure 1l is a cross-section of the invention when used as a traffic separator.

Figure 12 is a top plan of Figure 1'1.

More particularly, fence posts I are spaced along the side of a road. These posts mount parallel, vertically spaced, steel cables 2 which are tautened in the usual manner.` Preferably, the posts are spaced somewhat farther apart than is usual and are relatively strong.

Laterally spaced brackets 3 are xed to the cables 2 and right angularly project from them toward the traffic. The brackets may be made of heavy steel strips bent ir V-form and may have their ends-fixed to the cables by U-bolts 4.

A guard rail4 5 is mounted by the central parts of the brackets 3 so as to be parallel to the cables 2. This guard rail may consist of one or more lengths of steel strip which are mounted by the brackets in a. vertical plane and are joined in overlapped relationship, as at 6, with the end edges of the upper strips pointing in the direction of the trailics movement. It is obvious thatsuch a guard rail is flexible.

Each end of the guard rail is held against longitudinal displacement by a spring element. This Il)a screwed onto it. 'I'hen the end of the guard rail may be provided with a bolt I I which passes through a slot I2 in the spring element and is provided with a nut IIB. This last functions as a lock.

Braces 3 may be used between the ends of the brackets 3, if desired.

The fence posts I may be made from rolled steel sections providing a central at web Ia from which angular flanges Ih extend. The flanges IIJ may have apertures I through which U-bolts I3 are passed for the purpose of mounting the cables 2. In the case of "each end post, these U-bolts I3 may also serve to mount the plate 8, and auxiliary U-bolts I4 may be used to further x the cables 2 to this plate.

The operation of vthe ltraffic guard described is rather obvious. In case an automobile leaves the road it will strike the guard rail 5 and glide along it without striking the posts I. 'Ihe overlapped connections 6 being such that no proj jections oppose the automobile, no undue damage will occur at these points. The entire assembly is flexible and there is little chance of the stresses being concentrated at any one of the I I5. Also, the braces 3 shown by the preceeding ,y

figures are eliminated. l Figures 8, 9 and 10, respectively, show the guard rail or member as consisting of a cable I6 clamped to the brackets 3 by U-bolts l, two parallel cables I6* clamped to'the brackets 3 by T-members 42, and a ilattened cable Iiib clamped to the brackets by broad U-bolts 4b. l

" Figures l1 and 12 show a construction like that first described, except that the posts I8L are made of wood and the guard rail assembly is used in duplicate so as to separate two oppositely moving lines of tramcs We claim:

1. A tralilc guard Aincluding the combination of a post,'a spring-steel strip -bent in the form of a goose-neck and having oneend mounted on *Y Y said post, and a guard rail mounted by theother end of said spring-'steel strip and extending horizontally away from said post, said strip' and guard rail being interconnected by adjustable means whereby the tension applied to the latter by the former-may be varied. l

2. A tramo guard including the combination of a post, a spring-steel strip bent in the form of a goose-neck and having one end mounted on said post, and a guard rail mounted by the 5 other end of said spring-steel strip and extending horizontally away from said post, right angular brackets being oppositely xed to said strip and said guard rail and provided with an interconnecting screw fastening, and said strip and said guard rail having overlapping portions which are adjustably bolted flatly together.
