SWIMMING BUOY.

Application led September 5, 1922. Serial No. 586,305.

To all whom it may concern.'

Be it known that I, HENRY MAolnNzIE, a citizen of-Dominion of Canada, and resident of Stanmore, in the county of Medicine Hat and Province of Alberta, Dominion of A Canada, have invented certain new and useful Improvements in Swimming Buoys, of which the following is a specification.

This invention has relation to certain new and useful improvements in a swimming buoy and has for its primary object the provision of a device of this character which will be of extremely simple and inexpensive construction and which may be employed by parties learning to swim or lioat to keep them at the surface of the water.

The invention has for another object the provision of a swimming buoy which will be constructed in such a manner as to provide a handle between two air-tight members which are preferably of spherical form and bell-shaped form, respectively.

The invention has for a further object the provision of a swimming buoy of the character stated which will be composed of the minimum number of parts and which will be constructed of hollow metallic members having air-tight connections with opposite ends of a handle composed of wood or other material adapted to float on the surface while an auxiliary handle or stem is provided on the opposite side of the spherical hollow member and in alignment with the main handle.

With the foregoing and other objects in view, as will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application in which:

Fig. 1 is an elevation of the swimming buoy.

Fig. 2 is a longitudinal section through the device.

Fig. 3 is an enlarged detail section showing clearly the air-tight connection between one of the hollow members and the corresponding end of the main handle.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, 5 and 6 designate respectively the spherical and bell-shaped hollow floating members. These members 5 and 6 are preferably formed of thin metal and are air-tight. A handle 7 is employed to connect the members 5 and 6 and also serve as a means by which the device may be carried or upon which a party may rest when floating. The handle 7 is formed o-f Wood or other suitalble In'aterial and has -reduced end extensions 8. The spherical hollow floating member 5 has diametrically opposite radially directed tubes or nipples 9, one ofv which is engaged upon one of the end, extensions 8 of the handle 7. This tube or nipple 9 has portions 10 pressed inwardly into the handle end extension 8 over which it is engaged, as shown in detail in Fig. 3. I

The remaining tube or nipple 9 is mounted on the reduced end extension 11 of the auxiliary or stub handle 12 arranged in alignment with the handle 7. The second mentioned tube or nipple 9 should be pressed into the reduced end extension 11 of the auxiliary or stub handle 12 to secure together these parts and provide an air-tight connection between the same. Suitable rubber sleeves 13 are positioned around the tubes or nipples 9 and extend past the same onto the handle 7 and the auxiliary or stub handle 12, respectively, to further assure air-tight connection between the tubes or nipples 9 and the parts connecting therewith.

The bell-shaped hollow floating member 6 has its outer wide end closed by an end plate 14 having an annular outwardly directed ange 15 secured in a suitable and well known manner to the inner face of the bell-shaped hollow floating member 6, as shown in Fig. 2. The extension tube or nipple 16 projects from the small inner end of the bell-shaped hollow floating member 6 and is secured upon the remaining end extension i8 of the handle 7. This nipple 16 may be securely fastened in the same manner ing to learn to swim and ioat, the device serving to hold the party at the surface of the water as long as a firm grip is yretained upon the handle 7 or the auxiliary or stub handle'12. Both of thse handles may be held at the same time, if desired. It is furthermore apparent that the party may straddle or otherwise rest upon the handle 7 and thereby be properly supported betweenthe hollow floating members and A6. It will be evident to parties familiar with Y such devices that the side wall or body of the bell-shaped hollow lfloating member 6 will offer considerable resistance to the weater if the device should be positioned vertically within the water with the spherical hollow ioating member 5 directed downwardly.

While the preferred embodiment of the invention has been disclosed, it is to be understood that minor changes in the details of' construction, combination and arrange ment of (3o-operating elements kmay be resorted to within the scope of what is claimed without departing from the spirit of the invention.

What I vclaim as new is: Y

Aswimming buoyV comprising a handle having reduced end extensions; a spherical hollow lioating member having radial nipples projecting from diametrically opposite points; one of said nipples being mounted o-n one of the reduced end eXtensions of said handle; means surrounding said nipple and the adjacent portion of said nipple to forman airtight and water-tight connection therebetween; an auxiliary handle. projecting from the remaining .nipple of -said spherical hollow floating member; means for forming an air-tight and watertight connection between said auxiliary,

water-tight and airtight connection between said bell-shaped hollow floatingmember and said first mentioned handle. T

In testimony whereof, I afiixmy sig-nature.

HENRY MACKENZIE.
