Patented June 18, 1940 PATENT OFFICE I ROAD GUARD Carl C. Ahles, Albany, N. Y.

Original application July 8, 1935, Serial No.

30,374. Divided and this application July 20,

1939, Serial No. 285,630

2 Claims.

The present invention, which is a division of my application, Serial No. 30,374, filed July 8, 1935, relates to road guards. For a complete understanding of the invention, reference is made to the following description, the accompanying drawing and the appended claims.

In the drawing: 7

Figure 1 is a front elevation of a' road guard embodying the present invention;

Figure 2' is a plan view of the end of a road guard;

Figure 3 is a plan view of an alternative embodiment of the invention;

Figures 4 and 5 are plan views, respectively, of further alternative embodiments of the invention; and i Figure 6 is a top view of a construction which may be used in connection with road guards.

Referring more particularly to the drawing, as disclosed in the parent application, the invention relates to a road guard which includes a series of upstanding posts A suitably mounted in the ground. These posts carry brackets B having suitable slots C formed therein for positioning a plurality of flexible elements 99 which are held formed into a loop with its ends in overlapped in the slots by retainers E. The flexible elements 99 may take the form of wire rope or cable. The present invention relates particularly to theend anchorage means for flexible guard rail elements.

Figure 2 illustrates a post 96 to which a piece of fiat spring metal 91 is circumferentially fastened by means of a bolt 98. This piece .91 is relationship and the bolt 98 fastens this piece so as to permit relative movement of these overlappedends. A wire rope 99 terminates at the post 96 and is arranged around the piece 91 in collapsing relationship. In other words, this wire rope is wrapped around the, piece 91 so that the application of various tensions to the rope will cause the loop to collapse various amounts. This particular construction may constitute one of the ends of a complete road guard, the loop then functioning to tension the wire rope 99, the, latter then functioning as a guardrail.

Figure 3 shows the same construction as that of Figure 2, similar numbers being therefore used However, it is to be noted that in Figure 2 the end of the wire rope 99 is looped back onto itself and fastened by a clamp I00, whereas inFigure 3 this end is fastened to the post 96 by means of a hook-ended bolt IIlI that is passed through the post at right-angles to the bolt 98.

Figure 4 shows a post I02 to which a piece of fiat spring metal I03 is transversely fixed by means of abolt I I3, this arrangement being sim- 10 ilar to that illustrated by Figure 2 excepting that the piece I I2 is pierced at opposite points by the bolt I I3. A wire rope I I4 is wrapped around this piece II2, the difference between this andthe other constructions of a similar nature which have been disclosed being that the rope is passed between the spring loop and the post so that the bolt H3 is under tension.

Figure 6 illustrates a post I0! to which an endless loop of flat metal I98 is transversely fas- H tened by means of a bolt I09 which passes completely therethrough. A wire rope H0 is wrapped around this loop I08 in the same manner as was the case in the construction illustrated by Figure 2.

It is to be understood that all of the constructions illustrated are primarily intended to be used at the ends of a road guard for the purpose of tensioning or mounting the guard rail. Furthermore, that most of the various constructions which have been disclosed are characterizedby including a piece of flat spring metal strip that is transversely fastened to a post in such manner that relative movement of the ends of this strip is permitted. This enables the various forms of loops to collapse more readily when absorbing shocks.

I claim: I l. A road guard including the combination of a post, a piece of fiat spring metal formed into a loop and with its ends arranged free so as to permit relative movement of the same, said loop being mounted by said post so as to permit said relative movement, and a guard rail terminating at said post and arranged aroundsaid loop in collapsing relationship.

2. A road guard including the combination of a post, a piece of flat spring metal formed into a loop with its ends in overlapped relationship, means for fastening said loop transversely to said post so as to permit relative movement of said overlapped ends, and a guard rail terminating at said post and arranged around said loop in collapsing relationship.
