ROAD GUARD RAIL Filed Nov. 5, 1933 2 Sheets-Sheet 2 INVENTOR fMM /LM KMK ATTORNEYS Patented Apr. 23, 1 935 Ui'lED SAT? orrlcs 29 Claims.

My invention relates to improvements in road guard rails.

The object of my invention is to provide a guard rail adapted to be arranged along dangerous parts of highways and so constructed and arranged that it can be readily attached to posts or other supports suitably shaped and the attaching means serving as means for resiliently connecting and supporting the ends oftwo adjacent sections of the rails together.

Another object of my invention is to provide an elastic cushion to which the longitudinal members of the guard are attached and by its elasticity, tends to nullify the impact forces upon a vehicle which may. crash into the same and also to assimilate and absorb the force of the blow on the guard rail and also relieve the post or support nearest the point of impact of a greater portion of the force of the blow, by transmitting it to adjacent members.

A further object of my invention is to provide a guard of this type in which the longitudinal rail members are made in sections nearly equal to the distances between the posts or supports and in which the resilient means for connecting the guard rails to the post also connect the adjacent ends of two guard rails together whereby any shock on any guard rail is taken up by the guard rails on each side.

A further object of my invention is to provide a simple, cheap and efiective guard rail and its attaching means, in which shocks from any direction, either vertical, horizontal or oblique are more readily absorbed.

A further object of my invention is to provide a supporting means whereby expansion and contraction due to atmospheric conditions may be absorbed in each individual guard rail member.

A still further object of my invention is the arrangement of the supporting members, the manner in which they are brought through the ends of the longitudinal members so that they overlap the joint between the longitudinal mem-- bers.

Referring to the drawings, i represents a post or other support to which my improved guard rail is adapted to be attached. Secured to the post are two C-shaped attaching members 2 and 3, which are preferably made of heavy resilient steel wire and which are secured to the post by means of the plates d through which passes the bolts 5, which in turn pass through the posts and locked in a tight position by means of nuts, all of which is shown in dotted lines Figure 1 These attaching members are each made of a single piece of resilient steel wire formed in two C-shaped loops connected by the portion 7, thus each attaching member has two free threaded ends. Two attaching members are secured to each post or support and the ends of one member extending in the opposite direction to the ends of the other member as clearly shown in Fig. 1 of the drawings.

The guard rails ill and H are preferably made of flexible sheet metal and are of a length approximately equal or a little less than the distance between the centers of two posts or supports and at each end the rail is turned inwardly as indicated at l2, at an obtuse angle to the body thereof and then turned at right angles thereto as indicated at 13 forming a pocket in which a piece of metal it may be forced which form solid abutments for the tension nuts later to be described.

The end of the guard rail H] is provided with four openings it, it, E and i8, and the end of the guard rail ii is provided with four openings I9, 29, 2! and 22, all of said openings extending obliquely through the guard rails. The attaching member 2 has its ends 23 and 24 extending outwardly through the openings l5 and iii in the guard rail i0 and inwardly through the openings 59 and 29 in the guard rail H and through the turned end it of the rail and also through the piece of block l l. Secured on the threaded end are nuts 25 which abut the end it and whereby the ends of the two guard rails are drawn towards each other under the resilient tension. The attaching member 3 has its free ends 26 and ii threaded and extend in an opposite direction to that of the ends 23 and 2d. These ends extend outwardly through the openings 2i and 22 in the guard rail i and inwardly through the openings E1 and H2 in the guard rail Hi and have nuts 28 threaded thereon which abut the solid abutment of the guard rails and cause a further tension and strengthening of the attaching means.

By having these attaching means of resilient steel wire it will be seen that eachguard rail has a limited movement independent of each other for expansion or contraction of each rail, yet any shock on any guard rail is transmitted to other guard rails, whereby a greater resiliency is obtained. This is due to the fact that the ends of the guard railsare resiliently connected and any shock imparted to any guard is partly taken by the guard rails on each side and the connecting members for the post at their opposite ends. The steel wire attaching means passing loosely through openings in the guard rails allows, of a twisting of the guard rails. The attaching means also allow for an oblique or vertical absorbing means whereby injury to the rail or support is less liable to happen and provides the means for making necessary adjustments where the guard rail is constructed over hills or valleys.

In the modification shown in Figs. 2 to 1G, I have shown the resilient attaching members 23 and 38 of a Z-shape as clearly shown in Fig. 9 of the drawings. In this form the Z-shaped attaching means 29 is formed of a single piece of resilient steel wire having two Z-shaped portions 3! and 32 connected by the portion 33 and having the two ends 30' and 23d extending in the same direction. The attaching member 39 is connected exactly the same as the member with the two Z- shaped portions 35 and 35 connected by a shorter portion 37, whereby the two Z-shaped portions are within the Z-shaped portions of the other member. The last mentioned attaching member is arranged in the reverse position, so that its ends 38 and 39 extend in the opposite direction to the ends 33 and 34.

In the Z-shaped form of attaching means the ends thereof extend through the ends of the guard rails the same as the end of the C-shaped attaching means. That is the ends of one first extend outwardly through one rail and inwardly through the other rail, while the other the ends extend outwardly through the last mentioned guard rails and inwardly through the first mentioned guard rails. In this form the openings in the ends of the rails do not intersect the solid ends and in this case the beveled sleeves lu are provided which abut the thickened solid portion 4| of the rails and the nuts 42 cooperate with the ends of the sleeves. These Z-shaped members are connected to the posts by means of the plate 43 and bolts as. These Z-shaped connecting members also allow for a horizontal, vertical or oblique movement of the guard rails to take care of any shocks and are adapted to be used on the guard rails constructed as desc ibed in Fig. 1.
