CARL AGUST ZETTERBERG, OF DULUTH, MINNESOTA.
LIFE-PRESERVING- APPARATUS.
Specification of Letters Patent.
Patented Oct. 20, 1908.
Application filed March 27, 1908. Serial No. 423,690.
To all whom "it may concern:
Be it known that I, CARL Aonsr Zn'r'rnn- BERG, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented new and useful Improvements in Life-Preserving Apparatus, of which the following is a speciiication.
The invention relates to an improvement in life preserving apparatus and is directed particularly to a combined life preserver and swimming machine, whereby the user can easily support himself in the water and at the same time propel himself in any clesired direction.
The main object of the present invention is the provision of a suitable float which may be quickly and conveniently secured to the person, and which is constructed to permit propulsion when in the water, the propelling apparatus being within convenient reach of the user and being adapted for operation at any desired speed.
The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a lOIlgltllClllltIl section through an apparatus constructed in accordance with my invention. Fig. 2 is a transverse section through the same.
Referring particularly to the drawings, wherein is illustrated the preferred embodiment of details of the present invention, my improved life preserving apparatus comprises a base 1 of concavo convex shape in cross section and of substantial length. This base, which is preferably of wood or other light material, supports a casing 2, preferably of light metal, as aluminum. The casing is of approximately boat-like form in longitudinal and transverse section, and is arranged to support the operating parts, as will presently appear.
Depending from the base 1 adjacent each end thereof are a series of parallel frames 3, formed at their lower ends to provide bearings 4; in each pair of which is mounted a propeller shaft 5. The shafts 5 extend in opposite directions through the end walls of the casing 2, and are provided beyond said end walls with propellers 6, the detailed construction of which is immaterial so far as the present invention is concerned. A hanger frame 7 also depends from the base 1 within the casing and supports a drive shaft 8 arranged at right angles to the propeller shafts and having fixed thereon a bevel gear 9, arranged to mesh with bevel gears 10 upon the ends of the respective propeller shafts, it being understood that said propeller shafts are arranged in alinement longitudinally of the casing 1 so that the gears 10 of said shafts mesh with the drive gear 9 at diametrically opposite points on said gear. The drive shaft 8 depends through the bottom of the casing 52 and is provided with an operating handle 11, whereby the propeller shafts may be 'conveniently driven. A
To the side edges of the base 1 are se cured body straps 12, which are secured at one end to the base and are adapted for ad justable connection with the opposite edge of the base, as through the medium of con necting screws 13. Body straps, of which there. are preferably two, are designed to encircle the body of the user, and these straps are preferably elastic to insure a snug fit under all conditions.
The upper side of the base 1 is preferably covered by a cork section 14, which section is of greater length and width than the base. The cork section is designed primarily to render the apparatus suiiiciently buoyant to support the wearer, and, therefore, it is obvious that said section 1 1 may be replaced if desired by any other buoyant section, as for example an inflexible section or the like. The straps 12 are also secured. in relative position and the buoyancy of the apparatus as a whole is further increased by sections 15 of cork, which connect the respective straps at points remote from their connec tion with the base 1. In use when the wearer having adjusted the straps 12 to snugly fit the body will secure the apparatus upon his body with the head and feet extending beyond the respective ends of the buoyant section. In this position the apparatus is efi'ective in supporting the user in the water and the operating handle 11 is within convenient reach of the wearer so that he may by the use of said handle propel himself in any desired direction.
It is, of course, to be understood that the material of which the apparatus is to be constructed is to be selected with particular regard for its buoyant qualities, those parts which of necessity must be constructed of metal being of that character unaffected by immersion in water.
Having thus described the invention what i is claimed as new, is
1. A life preserving apparatus including a base, an inclosed casing depending therefrom, propeller shafts supported within the casing, means for operating said shafts, propellers carried by said shafts beyond the casing, body engaging straps projecting from the base, and buoyant sections connecting the straps beyond their connections with the base.
2. A life preserving apparatus including a base, an inclosed casing depending therefrom, propeller shafts supported within the casing, means for operating said shafts, propellers carried by said shafts beyond the casing, body engaging straps projecting from the base, and cork sections connecting the respective straps beyond their connections with the base.
3. A life preserving apparatus comprising a base of concavo convex shape in cross section, a buoyant strip secured to the base, an inclosed casing depending therefrom, propeller shafts supported within the casing, means for operating said shafts, propellers carried by said shafts beyond the casing, body engaging straps projecting from the base, and buoyant sections connecting the straps beyond their connections With the base.
i. A life preserving apparatus including a base of concavo convex shape in cross section, a buoyant strip secured to the base and conforming thereto in sectional contour, an inclosed casing depending therefrom, propeller shafts supported within the casing, means for operating said shafts, propellers carried by said. shafts beyond the casin body engaging straps projecting from the base, and buoyant sections connecting the straps beyond their connections with the base.
