Abstract

A pin puller, comprising a spring, a clamp, and a handle, which is used to pull the pins on the sliding tandem of a semitrailer. The pin puller may also be provided with a guard and a wire which has a flag on one end. When the pins are pulled, the flag will stick out so that the driver can see the flag emerge beyond the side of the semitrailer.

Claims

1. A device for pulling the pins of the sliding tandem frame of a truck semitrailer, said device comprising:

a spring having a ring at one end and a hook at the opposite end thereof;

a clamp comprising a first straight piece and a second generally L-shaped piece, wherein the shorter side of said second L-shaped piece is perpendicular to said first piece and the longer side of said second L-shaped piece is parallel to said first piece and defines a generally U-shaped space between itself and said first piece;

said clamp having defined into it a first opening in said first straight piece into which said hook of said spring is inserted,and a second opening defined into said longer side of said second L-shaped piece;

a combination locking stud and handle, wherein said locking stud is threaded and fits into said second opening defined into said clamp, and wherein said handle is formed perpendicular to said locking stud and wherein said handle has flattened sides;

a hollow, generally tubular guard fitted over said spring;

and a wire having a signal flag at one end, wherein said wire is tied around said spring and is passed to the outside through an eye formed into said guard, said wire extending a sufficient length so that said flag will extend beyond the semitrailer frame when the pins of the sliding tandem are pulled.
