CA LISTHENIO IM PLEMENT.

SPECIFICATION forming part of Letters Patent No. 239,796, dated April 5, 1881.

Application filed February 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, RALPH S. JENNINGS, a citizen of the United States, resident at Baltimore, in the county-of Baltimore and State of Maryland,have invented certain new anduseful Improvements in Ualisthenic Implements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as' will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, in which- I Figure 1 is a sectional view, and Figs. 2 ant 3 are modifications thereof.

This invention relates to improvements in devices to be used for exercise and health, denominated calisthenic implements.

The class of devices to which this invention specially pertains, by its construction and use, has been either made so that no adjustment of weight could be had, or else in a cumbersome and expensive manner.

It is the object of the present invention to construct a device which is exceedingly simple, and in which the weight can be readily adjusted.

The invention consists in a bat or club having a longitudinal bore, in which are to be placed cylinders of varying weights.

In the annexed drawings, A represents a hat or club, having therein a bore, B, running from the lower end, a, up into the body of the club, but stopping at the handle. At the top this bore has a conical seat, 12, at the center.

0 represents a plug for closing the opening of the bore, being held in any suitable manner. In the center of this plug is formed, on

material, and fill them with sand, iron-filings, &c. A definite weight is given to each of these cylinders, and the bore is out large enough to accommodate any one-of them, up to the largest. These cylinders are inserted in the bore, one head, d, resting in seat b, and the plugis put in the seat 0, coming over the other head, I), and made tight, which holds the cylinder central and rigid. In this way alight and tasty instrument can be made, the weight of which can be increased to suit different persons, or the different conditions of the same person, without altering the size or shape of the club itself.

Clubs. of only one size need be made and put on the market, the wants of different users being supplied by the weighted cylinders.

In Figs. 2 and 3 is shown a modification. In this form the end of the bore is cut angular, and in this recess is seated ablock having concentric rings, and the inner end of the plug.

made with corresponding rings, and the heads of the cylinders flanged, said flanges catching in these rings. Still further, there might be a recess in the heads of the cylinders, and a pin at the end of the bore and on the plug, to enter said recesses.

A metallic shell provided with adjustable weights and blocks for filling the upper and lower ends of the shell is already known; a policemans baton having a metal core is also old; but neither of these constructions is claimed herein.

What I claim is- 1. A club having a central bore and a cylinder located therein, in combination with a plug for closing the bore.

2. A club having a central bore, a cylinder located therein, and a plug for closing the bore and adapted to center the cylinder, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

RALPH S. JENNINGS.
