GUARDRAIL Filed Aug. 24, 1934 .M i MI HM I 0mm H l l Mln- Patented Aug. 10, 1937 GUARDRAIL Alan E. Brickman and George A. Gleason, Worcester, Mass., assignors to The American Steel and Wire Company of New Jersey, a corporation of New Jersey Application August 24, 1934, Serial No. 741,322

3 Claims. (Cl. 25E-13.1)

This invention relates to guard rails of the type using flat metal strips. In this type the strips are generally mounted in offset relationship from the posts by means of elastic members and sometimes cause trouble in that a colliding vehicle is thrown into the path of oncoming trailic by the rebound caused by the elasticity of these members. One of the objects of the present inventors is to diminish or eliminate this rebounding action.

vehicle, the strip 4 has backwardly angling edge portions 4a and is fixed to the bracket 2 by bolts 5 which pass through these portions and are therefore out oi the plane of the face of the strip. It follows that a vehicle sliding along the strip will not be torn by these bolts.

We claim:

1. A guard rail including the combination of a post, a metal strip extending transversely past l Other objects may be inferred. said post, and an offset bracket mounted by said l0 Referring to the accompanying drawing: post and mounting said strip, said bracket being Figure l is an elevation of an example of the constructed to distort when a colliding vehicle invention. strikes said strip and being made of metal that is Figure 2 is a cross-section from the line II-H sufficiently soft to prevent said bracket from l5 in Figure 1. springing back when once distorted. l5
