The anti-skid device is secured in place by means including a spring, constantly tending to bind the anti-skid device down upon the tire. This subclass takes such tensioning devices, per se, when specially adapted to this purpose, where no other securing means is combined therewith.
(1) Note. For the securing means without the continuing tension feature, in combination with the anti-skid device, see this class, subclasses 233-242.
(2) Note. For securing means, per se, with combined tightening functions, without the continuing tension feature, see appropriate subclasses in Class 24, Buckles, Buttons, Clasps, etc., especially, subclasses 68-70.
(3) Note. For tightening devices for use in application of the anti-skid device to the tire, and not having the
continuing tension feature, see Class 81, Tools, subclass 15.8 for tools to apply chains.
(4) Note. For such tensioning devices, per se, of more or less general application, see Class 267, Spring Devices, subclass 69 and indented subclasses.
