EXERCISING DEVI-CE.

APPLICATION FILED JUNE is. 1919.

EXERCISINGVDEVICE.

Application filed June 18, 1919.

To all whom it may concern:

Be it known that I, IcNATIUs J. AYD, a citizen of the United States of America, residing at Baltimore, State of Maryland, have invented new and useful Improvements in Exercising Devices, of which the following is a specification.

he purpose of the invention is to provide an exercising device simulating in form the dumb-bell, the device comprising a relatively long bar with hollow spherical cas-' ings carried at its ends, each of these casings being in the form of two hemispherical sections. The bar is, also designed to carry a plurality of disks at each end and the disks are of-such a character that they may be mounted on the bar and inclosed within the casings, the object being to vary the weight of the device at its ends by increasing or reducing the number of disks inclosed within the casings. The disks carried in each casing comprise a set and the whole set, when arranged side by side on the bar, forms a spherical conformation so that they may be snugly inclosed within the casing. Each disk is therefore a segment of the sphere and this beingthe case, the outermost'disks of the set may be removed to decrease the weight at that end of the bar and the disks remaining will be precluded from longitudinal movement because of contact with the inside walls of the casing which incloses them.

A further purpose of the invention is to provide a device of the character above mentioned which is simple in construction, durable and effective in operation and inexpensive to manufacture.

To illustrate and describe the invention a specific embodiment thereof is adhered to, but to this embodiment the invention is not to be restricted. The right is reserved to make such changes or alterations as continued use in practice may show to be desirable in so far as such changes or alterations are compatible in spirit with the annexed claims.

In the accompanying drawings:

Figure 1 is a view partly in elevation and partly in section showing the improved device.

Fig. 2 is an end view of the structure of Fig.1. 7

Fig. 3 is 'a plan view of one of the disks carried by the bar and housed within the spherical casing.

As shown, the invention comprises a bar Specification of Letters Patent.

' the bar nib lflush with the outer surface of the- Patented Dec. 23, 1919. Serial no. 305,152.

1 which is preferably circular in cross section and which is formed with threaded ends engaged by the nuts 2. A keyway is cut in the bar at each end and these keyways eX- tend from the terminals of the bar a specified distance toward the longitudinal center of the bar, each keyway terminating in a right-angled shoulder so that the keys 3 which are placed in the keyway may abut these shoulders at one end and have their other end abutting the nuts 2, so that longitudinal movement of the keys is precluded.

Each key 3 is formed at that end adjacent the shoulder with a nib or shoulder of its own, 4.

A spherical casing is carried at each end of the bar and the diameter of this casing is equal or substantially equal to the length of the key 3. The casing is formed in two hemispherical sections 5 and 6, both of these sections being formed with central eyes through which the bar 1 passes and the section 5 is recessed adjacent the eye to provide a seat in which the nib 4 of the key 8 may rest, so that section 5 may be precluded from movement toward the longitudinal center of and yet leave the outer edge ofthe section 5. The section 5 is formed with an annular nib 7 which defines a flange surrounding the corresponding end of the section 6 when the two sections are secured together, as they will be when both are placed on the bar 1 and the nut 2 is set down against the section 6. It is apparent that the construction just described provides for mounting the spherical casing on the bar so that it may be precluded from both longitudinal and angular movement on the bar when the nut 2 is attached, the eyes formed in the two hemispherical sections being obviously slotted so that the two sections may be passed over the key as well as the bar.

The design provides for the carrying of a plurality of disks 8 within the spherical casing and the whole set carried in either casing are of such a shape that when assembled side by side on the bar they have the shape of a sphere. Each disk therefore has a shape of a segment of the sphere which the whole set forms the central disk being obviously of the largest diameter and those on either side gradually decreasing in diameter to the two outside disks which are of the smallest diameter. Each disk 7 is formed with an eye 10 and a keyway 9 so that they may be mounted upon the bar and engaged by the key 3. The key prevents angular movement of the disks and when the whole set are assembled on the bar longitudinal movement of them is perforce precluded.

The greatest weight is had when the whole set are inclosed within the spherical casing. Desiring to reduce the weight, the nut 2 is removed, when the outer section 6 of the easing may be readily removed, the outer of the smallest disk 7 may be then removed and the section 6 replaced. The weight of the device is then reduced to the weight of the smallest disk 3 removed from either end. But with the removal of this smallest disk and the replacing of the section 6 the partial set of disks carried in each casing is securely held therein and precluded from longitudinal} movement along the bar because that disk which was adjacent to the one removed now abuts the inner wall of the casing instead of the disk which was previously adjacent thereto. Hence, it is seen that with the removal of one of the disks, the casing is employed to hold the partial set of disks in the same intimate contact as they were held when the set was whole. It is obvious that it is desirable to have the disks mounted so that they may not slide along the bar. Were this possible and were only one disk carried in the casing, that disk might slide from one side of the casing to the other and would obviously cause a variation in weight at the end of the bar when the latter is in use.

The system of reducing the weight by the removal of the disks 8 constitutes the removal of the outermost disks 7 and greatly reduces the weight by. removing the next succeeding disk, until finally the smallest weight is had by removing all the disks and leaving only the central disk within the casing and this will obviously be held against longitudinal movement along the bar when the two sections of the casing are attached.

Of course, the device may be still further reduced in weight by the removal of this central disk, leaving only the casing to provide the weight at the ends of the device.

The invention having been described, what is claimed as new and useful is:

An exercising device, comprising a bar, keys set in the bar adjacent its ends and extending in the direction of the length thereof, those ends of the keys remote from the ends of the bar being formed with nibs, casings comprising two hemispherical sections,

each of which are formed with eyes and keyways to permit them being mounted on the bar and engaged by one section of the key, one section of each casing being slotted to form a seat for the nib of its attendant key,

nuts threadingly engaged with the terminalsof the bar and bearing against the other sections of the casings, and a plurality of disks formed with eyes and keyways and mounted upon the bar within the casing so that they may be precluded from both angular and longitudinal movement on the bar, the disks being individually removable for the useful purpose specified.

In testimony whereof I affix my signature.
