Abstract
Abstract A pair of handles, mounted individually on the ends of a coil spring, the ends of the spring extending longitudinally into the ends of the handles, and the coil thereby being positioned beyond the handles. A light bulb and battery are included in one of the handles, and conductors, including the spring, connect the light bulb and battery in circuit, and terminate in contacts in the ends of the handles remote from the spring, and upon interengagement of the contacts, they complete the circuit and turn on the light. In squeezing the handles, in exercising the hand, illumination of the light signals the interengagement of the handles.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
A handgrip comprising, a pair of elongated handles to be gripped by the hand and of a size to be engaged by the whole hand throughout the width of the hand, means mounting the handles together for movement of the handles toward and from each other in pivotal movement about a pivot axis that is disposed longitudinally beyond the handles whereby substantially the whole body of the hand grip is disposed longitudinally beyond the pivot axis, the mounting means including spring means biasing the handles apart and yielding to enable the handles to be moved toward each other into interengagement, and the spring means being of great strength whereby the handles can be moved into such interengagement only by the full strength of the hand, the handgrip including an electrical circuit which itself includes a battery, light bulb, and contacts, one of the contacts being in each of the handles, and the contacts being exposed for interengagement in response to the handles being moved into interengagement, and effective when so interengaged for completing circuit and lighting the light bulb, the electric circuit being normally open and closed only when the handles are interengaged.

Claim 3
Dependent Claim
41 words
A handgrip according to claim 1 wherein, the contacts are disposed at the extreme end of the handles remote from the pivot axis, whereby to effect lighting of the light bulb only when the handles are in extreme and full interengagement.
Claim 4
Dependent Claim
67 words
A handgrip according to claim 1 wherein, the mounting means is constituted solely by the spring means, and the spring means is in the form of a torsion coil with linear end elements extending therefrom, the end elements extend into the handles and constitute the means by which the handles are mounted on the spring means, and the spring means constitutes a portion of the electrical circuit.
