ABM DEVELOPER.

Application filed February 3, 1926. Serial No. 85,793.

This invention relates to an exercising device primarily designed for use in developing the muscles of the wrists and arms, one of the objects being to provide a simple, compact and efficient structure which can be adjusted readily to the strength of the user and which has means whereby, each time the device is raised or lowered to a predetermined angle, an audible signal will be sounded.

lVith the foregoing and other Objects in view which will appear as the description proceeds, the invention resides in the'combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a side elevation ofthe device showing the same in use, one position being indicated by broken lines.

Figure 2 is a plan View, broken away.

Figure 3 is a longitudinal section through the adjustable weight and adjacent parts, the handle and a portion of the stem being shown in elevation.

Figure 4 is an end elevation.

Referring to the figures by characters of reference 1 designates a stem or shank to one end ofwhich is secured a handle or grip 2 preferably cylindrical and extending at right angles to the stem or shank and at opposite directions therefrom. Mounted to slide on the shank 1 is a sleeve 3 the ends 4 of which are screw threaded and seated within threaded sockets 5 formed within terminal collars 6. These collars are likewise fitted loosely on the shank 1 and one of them has a set screw 7 or the likewhereby the sleeve and its collars can be held againstrotating and sliding movment relative to the shank. The weight 8 preferably in the form of a thick disk of heavy metal is mounted to slide freely on the sleeve 3, the. thickness of this disk a portion being being slightly less than the distance between the collars 6. Thus the weight has a limited sliding movement between the collars.

In using the device the handle 2 is grasped tightly with the hand and, without bending the arm but merely by working the wrist, the user swings the shank or stem 1 upwardly and then downwardly. When the shank or stem reaches a predetermined angle at either limit of movement, the weight 8 slides from one extreme position to the other. When it is brought to a stop by contact with one of the collars 6, a clicking sound is produced which indicates to the user that the necessary movement has been completed. Obviously the device can be used by exercising the arm in other ways. For the purpose of adjusting the device to the strength of the user the sleeve 3 and the set screw have been provided. By loosening the set screw the sleeve can be adjusted along the stem or shank, thereby to bring the weight to a point at a desired distance from the grip or handle 2. The screw 7 can then be tightened to fasten the parts against dis placement. Under all conditions, however, the weight 8 has the same limited movement between the collars so as to produce the de sired clicking sound each time the proper movement of the device has been completed.

What is claimed is:

1. A device of the class described including an elongated stem, a grip at one end thereof, a sleeve adjustable longitudinally of the stem, means for holding the sleeve against movement relative to the stem, and a weight having a limited sliding movement on the stem.

2. A device of the class described including a stem, a grip at one end, a sleeve adjustable longitudinally along the stem, a weight slidable on the sleeve, means at the end of the sleeve for limiting the movement of the weight on the sleeve and for cooperation therewith to produce a clicking sound upon the completion of each sliding movement of the weight, and means for holding the sleeve against movement uponthe stem.
