US Patent:

43913156, Jul 5, 1983

Filed:

Jul 13, 1981

Appl. No.:

6/282505

Inventors:

Gerald D. Jacobson - Everett WA

International Classification:

B60C 2700

US Classification:

152213A

Abstract:

An anti-skid tire chain is improved by having a resilient strap at one end, the strap being adapted to be secured on the inside wall of a mounted tire having its tread on a road surface. On both of the side wall links of the chain, there are plates having a plurality of sharply pointed hooks or barbs adapted to be pressed into the side walls of the tire when the chain is initially being secured to the tire. In order to have the barbs securely engage the tire so as to hold the chain thereon during the rotation of the wheel and tire, the resilient strap is extended transversely on the chain from adjacent one of the plates to the other and the plates are secured to the tire by pressing them against the side walls with the barbs extending toward the tire wall and toward the tread. At the same time the strap is stretched so that when it is released, the barbs will be additionally pulled into the tire by the resilient retraction of the strap. The barbs do not damage the tire but hold the chain thereon while the tire is rotated so that the opposite ends of the chain can be brought adjacent each other and secured together.

International Classification:

Abstract:

A roll of tack-strip is supported on a cradle of rollers carried by a wheeled frame. The tack-strip having its tack-point side down, extends over a bristle guide roller and through a nip formed by and between a pair of bristle rollers to a nailing station located at a lower rear corner portion of the machine. As the frame is pushed by an operator around the perimeter of a room the tack-strip is unwound from the roll, guided into a position on the floor next to a wall or the like, and nailed into place. A cutter located between the roll and a nailer is operable by the push of a button to cut the tack-strip at the end of a run. The machine is operable to feed out a measured length of tack-strip while the machine is not moving, so that the operator can cut off short lengths of tack-strip. The nailer is removably mounted within the machine so that the operator can lift it out of the machine and use it for installing the short lengths at locations where the machine cannot be used for installing the tack-strip.
