Abstract: The invention comprises a combination vise and breaker pin for facilitating repair of metal drive chains. The vise serves to pull the links of a chain together so that tension is maintained throughout the chain while links between vise jaws become loose and readily repairable. This feature is combined with a breaker pin moving within a hollow channel axial of a full thread hex head bolt. A breaker point having an annular shoulder is attached at one end of the breaker pin. The breaker pin is free to slide back and forth within the bolt except as limited by the annular shoulder. The breaker pin cooperates with a U-shaped cradle suitable for holding a link. The breaker point is brought into contact with the center bearing of a chain link when the left and right-hand jaws of the vise are moved toward one another. The bolt carrying the breaker pin is then tightened against the chain link bearing pin.

Abstract: A self contained alarm device is disclosed for aiding in the prevention of the theft of articles from an automobile, such as a citizens band radio, by sounding an audible alarm in the event of an attempted theft. The device includes a box or container in which the article to be protected is mounted and at least one switch mounted on the outside of the container for articles, and at least one switch between the container for the articles and the lid for the container so that removing the container from the surface on which it is mounted will cause an audible alarm to be sounded. One embodiment of the device also includes an electrically conducting wire forming a loop outside of the container for encircling an element of the automobile such as the steering column so that if the loop is cut, the audible alarm will also be sounded.
