Description:

This was the first patent for tire chains.

Abstract:

This invention relates to improvements in io treads for pneumatic tires, and is particularly applicable for use on the traction-wheels of automobiles to prevent the tire from slipping on slippery pavements. The object of my present invention is to provide a flexible and collapsible grip or tread composed entirely of chains linked together and applied to the sides and periphery of the tire and held in place solely by the inflation of the tire, and which is reversible so that either side may be applied to the periphery of the tire, thus affording a double wearing-surface. These grips or auxiliary treads are adapted to be applied to the traction or driving wheels of automobiles, and one of the important objects is to enable any one skilled or unskilled to easily and quickly apply the auxiliary tread when needed by partially deflating the tire and then placing the grip there- on, and finally reinflating the tire to cause the transverse chains to partially embed themselves into the periphery of said tire, whereby the auxiliary tread or gripping device is firmly held in operative position against circumferential slipping on the tire. Another object of equal importance is to construct the auxiliary grip or tread in such manner that it may he collapsed into a minimum space when not in use to be carried in the vehicle, and owing to the fact that it is to constructed of chains with comparatively short links it will be apparent that it may be compressed into a very small space, and therefore can be placed under the seat or in any other available receptacle in the vehicle.

Claim:

A grip-tread for elastic tires comprising two parallel side chains having a plurality of hooks at one end to receive the links of the opposite end, and cross-chains linked to the side chains and having both faces alike whereby either face may be presented to the tire.
