GEORGE O. BUNSEN, OF MILWAUKEE, WISCONSIN.
SWIMMING APPARATUS.-
SPECIFICATION forming part of Letters Patent No. 516,963, dated March 20, 1894.
Application filed August 24. 1893. Serial No. 483,957. (No model.)
To aZZ whom it may concern.-
Be it known that I, GEORGE C. BUNsEN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Swimming Apparains; 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.
My invention relates. to improvements in swimming apparatus forpro'pelling the bodies of both men and animals through the water and its principal object is to provide an improved device that can be readily attached to the person or animal using it and which will open and close alternately according to the direction of its movement and thus offer greater or less resistance to the water alter- Iaccomplish this object by the construction and combination of devices as hereinafter more particularly set forth anddescribed in detail.
In the accompanying drawings forming part of this specification, Figures 1. and 1 represent side elevations of devices embodying my invention attached to the arm of a swimmer and held by his hand. Fig. 2. represents a. rear elevation of said devices showing them attached to a swimmers leg. Fig. 3. represents a central vertical section of the device which is to befgrasped by the hand. Fig. 4 represents a detail perspective view of a conical or tapering grooved core forming a part of my invention. Fig. 5.represents a cross section of the same on the line w-:c of Fig. 4. Fig. 6 represents a perspective view of the core provided with ribs forming part of my invention. Fig. 7 represents a plan View of part of a flexible covering used in connection with said core. Fig. 8 represents a plan view of a covering for the handle of the device. Fig. 9 represents a plan view of a piece employed for connecting the core to the covering of said ribs. Fig. 10 represents acentral vertical section of the complete propeller without its attaching devices Fig. 11 represents in detail perspective the mode of attaching the ribs to a single covering. Fig. 12 represents in perspective a modified form of the frame work, of the device for the arm.
in perspective a modified form of the device for the leg. Figs. 14. and 14 represent modified forms of leg propellers with leggins and straps, partly in vertical section and partly in side elevation. Fig. 15 represents a bottom with its arm casing and straps. Fig. 16 represents a side elevation of my propeller as applied to the right fore leg of a horse. Fig. 17 represents the same as applied to the back left leg of a horse and Fig. 18- represents a rear elevation of the propeller used for horses with its fastening straps.
The opening and closing propeller represented in the drawings when it is to be attached to the arms and legs, is formed principally of a flexible framework covered with a web of some flexible material which assumes, when open, the form of a hollow cone. This framework is composed of ribs B of some flexible material such as Indian reed, tough wood or steel. These ribs are mounted on a conical or tapering core A which is provided with grooves a. lined with putty, wax,whitelead or other similar material into which said ribs are pressed and secured thus making a water and air tight joint at this point. The middle portion of said ribs where they are attached to said core is cut away or thinned as at b. to make them more flexible at this point where great flexibility is required because of the opening and closing action of the propeller. The outer end of each rib is provided with a tip I) which consists of a small section of rubber tubing slipped upon it to keep itfrom cutting the covering 0 which surrounds it. This covering consists of two pieces of sail cloth or like material, cut as shown in Fig. 7 and stitched together at their peripheries. Between said pieces 0 is secured by stitching c. the cord 0' which limits the opening of the conical propeller when the device is in use. A piece D of material similar to that of part 0 is cut as shown in Fig. Sand has its periphery d. d. shown on the line e. e. of one of the parts 0 while a piece E has its periphery e ve shown on a similar line of the other parfiO. The two parts 0. O. are stitched together as at f. f. Fig. 7. to form channels to receive the ribs B. When the ribs are in place the part E. is attached to the top of the tapering core Fig. 13 represents A by a screw f and forms a water and air View of the modified form of arm propeller tight joint at this point, the edges g. g. and h. h. having been first sewed respectively together. The part D. is then wrapped around the lower ends of the ribs Band fastened thus forming a handle F. The outer ends of the ribs B are secured by wire or otherwise to the cord 0. The completed propeller as shown in Fig. 10 is then attached to a sleeve I provided with fastening straps z'. for the arm or to a leggin J having fastening straps j. for the le The leggin J. is also provided with a stirrup strap j which passes under the instep of the foot and thus keeps the propeller from slipping up the leg when 1n use.
Sometimes I use a single piece 0' when lightness is required, attaching the ribs thereto by means of strips 0 as shown 1n Fig. 11, the cord 0 then being inclosed in a hem on the periphery of parts C. By this construction of the web covering the ribs, the propeller is made about one third lighter which would be very desirable in some propellers such as are used in races for instance. The propeller to be grasped by the hand is constructed in a slightly different manner, see Fig. 3. In this case the ribs 9 are made of some stifier material and connected to the core H by flexible strips g of rubber belting or the like thus allowing the propeller to open and close as before. The ribs are made fiat and leave their ends riveted in a hem of the web covering G which is out similar in shape to part 0 and has a piece Gr simllar to part D sewed to it. The ribs do not form the handle as in the former case but are cut off short before reaching the core to which they are flexibly connected. The grasplng handle is formed by a prolongation of the core H, and is provided with a cord to he slipped over the wrist and thus prevent the swimmer from losing the propeller as he lets go of the handle to use his hands.
The modified form of arm propeller shown in Fig. 12. has a fiat core K provided with grooves 10. into which the flexible ribs are fastened, the latter being first cut away or thinned if metal as at b? to make them more flexible also to make them form an even surface with the core when set in the groove thereof. The coverings C and D are then put on as in the first instance and the sleeve I and straps 1'. attached thereto. This form of arm propeller is very light and can readily be supported because of the fiat sides of the core which rest against the arm.
The form of leg propeller shown in Figs. 13 and 14.: have no core and consequently is very light and convenient. All the ribs except two are cut off short and all are cut as at bf. Fig. 13 to make them more flexible at this point. The two ribs that are not cut short form the handle which is covered with a casing F which in turn is attached to the le gin J as before described. Either the style of covering shown in Fig. or that shown in Fig. 11 may be used in this case and 1n the ward as far as he pleases.
fiat cored arm propeller, to cover the ribs, as preferred.
In Figs. 16 and 17 the propeller is shown as attached to a horses leg although it might be a dogs or any other swimming animal. When used on a horse the propeller is attached to the outside of each leg below the knee joint so that the respective legs will not interfere with each other when swimming or walking. The device for this attachment consists of a stid piece L of leather or similar material which has raised upon it a ridge Z adapted to fit into the longitudinal cavity of the lower part of a horses leg. An aperture Z is cut in the part L to fit over the hoof joint and the whole is attached by straps m. The propeller is attached to the outside of this part L., the latter by its peculiar construction being incapable of turning on the animals leg so as to interfere with the opposite leg.
All the joints of the conical propellers must be made water and air tight as the swimmer is often obliged to rest by supporting himself with air confined within said propellers by holding them with the handles vertically up.
The operation of the propellers is as follows: Upon a forward motion of the arms or legs, the propellers all close because of the water resistance and the unrestrained flexibility of the ribs in that direction, but upon a reverse movement they all immediately open their full extent, oifering great resistance to the water and forcing the swimmer forward rapidly. The movement is then repeated with the same result as before. If the swimmer wishes to dive he turns the handles of the hand propellers down and gives them an upward thrust which starts the diving movement. He can then swim down- When he wishes to come to the surface he can simply reverse the hand propellers and thus alter the direction of his movement which will bring him up at once. These propellers can of course be attached directly to swimming or diving suits and thus do away with the sleeves and leggins. The propellers are also found very useful as life preservers as with two of the hand propellers a person can keep himself afloat for an indefinite time by simply inverting them and pressing them down upon the waters surface. The air confined within them will keep the person up. This supply of air may be renewed by alternately lifting them and setting them down again upon the surface. By the use of these propellers a swimmer can swim very rapidly and for great distances as the ease with which he forces himself forward and keeps afloat does not tire him. Treading water or standing upright in the water becomes very easy.
The material to be used for the ribs may be flexible reed, as before mentioned, or other tough and elastic, wood, and in some cases,
IIO
where great strength is required, may be of steel or other flexible metal.
As shown in Fig. 14* I have two propellers attached to a leggin in such manner that when adjusted to the wearer they will rest upon the front of the leg and so be capable of opening whether the swimmer strikes out with his legs, either diagonally to the right or left. The stirrup in this instance is attached to the bottom of the two inside ribs of the lower propeller. The upper propeller has all its ribs cut off short, thus leaving no extending ribs to form a handle as is the case with the lower propeller. Two small propellers will open'much quicker than one large one, and in some cases this form is much to be preferred.
In Fig. l I show the propeller as attached to the side of the arm with its sleeve extending above the elbow where it is provided with a strap.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-.
1. A swimming propeller composed of flexible ribs bound together to form an attaching portion and a web covering for said ribs, substantiallyas set forth. I
2. A swimming propeller composed of flexi ble ribs, a core upon which said ribs are mount- 3 0 taching portion and having a web covering and suitable devices for attaching the same to the arm or leg, substantially as set forth.
4. In a swimming propeller thecombination of flexible ribs, a core to which said ribs are attached, a web covering for said ribs and devices for attaching the whole to the wearer, substantially as set forth.
5. In a swimming propeller thecombination of flexible ribs having a web covering a leggin attached to the same and provided with a stirrup strap, substantially as set forth.
6. In a swimming propeller the combination of flexible ribs having a web covering a core upon which said ribs are mounted, said core having a prolongation forming a handle, substantially as set forth.
In testimony whereof I hereunto affix my signature in presence of two witnesses.
