JOHN M. REINERS, OF NEW YORK, N. Y.

HAND-GRIP TESTE R.

SPECIFICATION forming part of Letters Patent No. 374,003, dated November 29, 1887.

1 Application and April 5,1ss7. Serial No. 233,711. No model.)

To all whom it may concern:

Be it known that I, JOHN M. REINERs, of the city, county, and State of New York, have invented a new and Improved Grip-Tester, of which the following is a full, clear, and exact description.

My invention relates to an improvement in hand-grip testers, and has for its object to pro vide a device for testing or registering the grip of the human hand, which will be simple in construction and accurate in registry.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification,

in which the figure illustrates an elevation of the machine, partly in section.

Two upright posts or standards, A A, are mounted upon a fiat base-piece, B, connected about centrally their length bya transverse bar, B,which bar is slotted longitudinallyand pro vided with an upwardly-inclined recess, 0, upon the under side, extending from one end to or near the center. The opposite end of the slotted bar B is provided upon each side with a series ofhorizontally-aligning graduated apertures, b, and the inner lower edges of said slotted bar below the apertures are provided with ways 1), upon which slide a double frame, D, carrying ordinary cutting-blades, d, one blade for each aperture. The blades are kept normally out of registry with the apertures by a spring, d, attached to the rear of the sliding frame D and bearing against the inner end wall of the slotted bar B. The double cutting-frame is operated by an attached horizontal rod, D, passing through the opposite end of the said slotted bar and through the standard A, being provided at the end with a thumb-piece, D. By pressing the thumb-piece the ends of cigars placed in the apertures b are cut-and the said ends fall into a receptacle, D attached to the slotted bar below the cutters. An arm, E, is pivoted to the inner side of the post A at the base, and said arm E is provided below the center with an elongatedaperture, E, through which a horizontal rod, e, capped at its outer end and attached to the said post A, is made to extend, having an encircling coil -spring, E, which spring has-a hearing at one end against the post and at the other against acollar, 6, formed on said arm about the aperture E.

Below the aperture E, upon the outer surface of the arm E, a number of depressions, F, are f0rm'ed,adapted to receive the fingers when the instrument is grasped with the hand. The upper portion of the arm E is reduced and made to extend upward through the slotted bar B, the shoulder f, formed by said reduction, being adapted to travel along the un-.

der surface of the inclined recess 0. The tops of the posts A A are united by parallel trans- Verse strips G, and centrally within and between said strips a pinion, g, is journaled,provided with square posts, each side projecting out through duplicate and parallel dial-plates H, numbered upon their outer faces.

Indicating-hands H are secured to the posts of the pinion g in front of each dial, which hands are operated from the arm E through the medium of a rack, M, engaging the pinion g and sliding in the posts A A. Upon the lower edge of the rack a shoe, m, is formed, which normally engages the upper extremity of the arm E.

In operating the device the arm E is grasped with the fingers and pulled slowly toward the post A. The upper end of the arm E, being in engagement with the rack,will carry the said rack to the right, moving the hand,which will thereupon register the test. As soon as the arm E is released, it returns to its normal position, leaving the hand indicating the number of pounds. To place the hand in position for another test the projecting end of the rack is grasped and the shoe m is again brought in contact with the arm E.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

- 1. A hand-grip tester comprising opposing dials supported by standards A A, a pinion pivoted between said dials, carrying indicatingfingers, a rack sliding in said standards, operating said pinion, an arm, E, pivoted to one standard, and a spring adapted to bear against the standard and arm, the said arm being adapted to operate the said rack and individed with a shoe, in, integral with the under eating-finger, substantially as set forth. edge, all arranged to operate substantially as 10 2. In a hand-grip tester, the combination, herein shown and described.
