6 Claims. (Cl. 25613.1)

The present invention, which is a division of Figure 2 is a plan view illustrating a guard rail supporting bracket embodying the present invention;

Figures 3 and 4 are plan views illustrating modified embodiments of the invention; and

Figure 5 is a view partly in section and partly in elevation of the embodiment of the invention shown in Figure 4.

Referring in detail to the drawing, the presentinvention is concerned with detail features of the guard rail and its supporting means disclosed in the above identified parent application. The guard rail, as illustrated in Figure 1, comprises a plurality of flexible elements A such as ropes, cables or flexible bands which are adapted to be resiliently mounted by spring brackets, indicated generally at B in Figure 1. The present invention relates specifically to the mounting brackets which are illustrated in detail in Figures 2 to 5, inclusive.

Continuing, in Figure 2 a wood post l3 mounts by means of a bolt H a piece of flat metal l5 that isformed into a cylindrical loop with its" respective ends overlapped at one side, as at IS. A wire rope I! extends transversely past the post I3, and clips l8 fasten this rope to the outside of the piece l5 at a position ofiset from and opposite to the post l3.

In the alternative embodiment illustrated in Figure 3 the post 24 mounts a piece of flat metal 25 that is formed into the form of a loop with its ends 26 curved inwardly so that their outer surfaces contact. A bolt 21 fastens one of these ends to the post 24. A wire rope 28 extends transversely past the post 24 and is fastened to the piece 25 by means of a clip 29 in the same piece of flat spring metal 88 is transversely fastened by means of a bolt 89. This piece is curled into a loop with its end 90 telescoped inside of the same, and its portion opposite the post 81 is provided with a series of apertures 9| arranged in vertical alinement. A plurality of wire ropes 92 extend transversely past this post adjacent these apertures 9|,and U-shaped clips 93 engage these strands 92 and have portions 94 which extend inwardly through the apertures 9|. These portions 94 are apertured in directions transverse of the loop, or vertically, and are therefore in parallel alinement with the post 81, and a pin 95 is passed transversely through them so as to retain them in position.

I claim:

1. A road guard of the character described, comprising a series of posts, a series of looped re- Y silient sheet metal supports each having a pormanner as in the'case of Figure 2. It is to be noted that in this form the ends of the piece 25 are likewise arranged free so as to permit relative movement of the same, and the mounting of movement.

In the embodiment of the invention illustrated in Figures 4 and 5, there is a post 81 to which a tion adjacent the post rigidly secured thereto,

the extremities of each looped support being free to move relatively to each other under impact, a guard rail comprising a plurality of vertically spaced cables extending from support tosupport' and in juxtaposition with the outer surfaces thereof, and respective means mounting each cable on each support with freedom for independent longitudinal sliding movement relative to such support.

2. A road guard of the character described,

comprising a series of posts, a series of looped resilient sheet metal supports each having a portion adjacent the post rigidly secured thereto, the terminal extremities of each looped support contacting and movable with relation to one another, a guard rail comprising a plurality of vertically aligned cables extending from support to support, and respective clips interlocked with the supports and loosely embracing the cables to permit them to partake of unrestricted independent longitudinal movement with respect to the supports. 7

3. A road guard of the character described, comprising a series of posts, a series of looped resilient sheet metal supports each having a portion adjacent the post rigidly secured thereto, the terminal extremities of each looped support contacting and movable with relation to one another, a guard rail comprising a plurality of vertically aligned cables extending from support to support, each support having a series of apertures formed in its portion opposite the post, respective U-shaped clips embracing each of said cables and having portions extending through the apertures in the supports, each clip being perforated in a direction substantially perpendicular to the cables, and a retainer pin piercing the perforations in said clips, the parts being thus constructed and arranged to permit free longitudinal sliding movement of the plurality of cables relative to each of said supports.

4. A guard rail construction comprising a series of posts, a series of tube-like sheet metal springs mounted on the posts by means rigidly securing a portion of each spring to a post, the springs being of looped form with their extremities contacting and freely movable relative to one another under force of impact, a guard rail extending alone and in engagement with the front portions of the springs, said guard rail comprising a plurality of vertically spaced flexible cables, the springs being yieldable toward the posts upon impact of a vehicle with the rail and the rail being connected directly to and carried by the springs through the agency of means allowing unlimited sliding movement of the cables relative to the springs, the springs being substantially unyieldable in a vertical direction and thereby maintaining their roadside portions substantially vertical, thus serving to maintain the cables in vertically spaced relationship.

5. A guard rail construction comprising a series of posts, a series of tube-like sheet metal springs mounted on the posts by means rigidly securing a portion of "each spring to a post, the springs being of looped form with their extremities contacting and freely movable relative to one another under force of impact, a guard rail extending along and in engagement with the front portions of the springs, said guardrail compris- .8 a plurality of vertically spaced flexible cables, the springs being yieldable toward the posts upon impact of a vehicle with the rail and the rail being connected directly to and carried by the springs through the agency or apertured clips embracing cables and extending through slots in the springs and including a single retainer pin for each spring common to the clips of all 01' the cables supported thereon.

6. A road guard comprising a series of spaced posts, a series of resilient sheet metal brackets each having an inner fixed portion rigidly secured to a respective post and a flexible portion spaced outwardly therefrom, each bracket being so shaped in plan and so constructed and arranged that the free extremity thereof can be readily flexed inwardly toward the zone of the post under impact, a guard rail composed oi a plurality of cables arranged one above the other and extending from bracket to bracket in contact with the yieldable outer portions thereof, said brackets being adapted to yield upon impact of a vehicle with the guard rail, and retaining members carried by the brackets and making a free sliding 111; with the cables so that any cable may move independently of its neighbor with relation to any bracket, said brackets being unyieldable in a vertical direction and thereby maintaining their roadside portions substantially vertical, thus serving to keep the plurality of longitudinally movable cables constituting the guard rail in spaced relation one above the other.
