SWIMMING erPARA'rUsQ 7 Application filed. September To all whom it may concern:

Beit knownthat IyInvmo rename, a citizen of the. United States," and a resident of Kansas City, .in the county of Jackson and State of'Missouri, have invented a certainnew and'useful Improvement in Swimming Apparatus, of which the following is. a specification. i 1

My invention relatesto improvements in swimming apparatus. It relates to an apparatus which has sufiicientbuoyancy tosupport a person, and which has means for being propelledb y the persona One of the ob'ects of my invention is to provide a novel swimming apparatus ofthe icind described, which is simple, cheap, durable, not liable to get out of order, which is adapted for use by persons of; different height, which is safe, and which will afford exercise and enjoyment tothe user while enabling him to learn the art of swimming.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which" illustrates the preferred embodiment of my invention, 7 I Fig. 1 1s a perspective view of my improved swimming apparatus Fig.- 2 1s a side elevation of the same. Fig. 3 is an enlarged sectional v ew on the line 33 of F1 2.

'Similar reference characters fdesignat-i I similar. parts in the different views.

A buoyant support is provided, which may comprise a frame consisting of twospaced apart floats, which may be two boards 1, to which are fastened at] the inner edges thereof respectively two rearwardly extend ing wooden bars 2, to the inner sides of each i of which are. fastened two depending vertical bars Two longitudinal bracebars 4 are respectively fastenedto the under edges and rear ends of the bars 2, and to the inner sides of the adjacent depending bars? A body support comprising a horizontal transverse board 5,has its ends respectively fastened to the inner sides of the brace bars t in substantial alinement with the transversemiddle portions of the fioatsl'.

A transversehandheld bar .6 may be fas-. tenedat its ends to the forward ends respectively of the floats 1.

Propelling means for. the a paratus may consist of two propellin whee is, which are, preferably, paddle whee s 7, which are respectively fastened to and rotatable with two lon 16, 1925. Serial in. 56,634. i

transverse alined shafts 8. Two )airs of bearings 9 arerespectively mounteoo-n the upper sides of the floats-1 andihave respectively 'rotatably mounted 'inthem the shafts 8. i 1

For rota'ting'the shafts 8, there are ie spectively secured to, them two bevel gear wheels 10which respectively mesh with two bevel gear wheels 11, which are respectively rigidly, secured to. two longitudinal shafts 12, which are rotatably mounted adjacent to.

their forward ends in transverse plates 13, which are respectively fastened between the pairs of hearings 9; The rear portions of the'shafts 12 are respectively rotatable and longitudinally slidable in two lugs 14; respectively provided on the." outer sides of two bearing members 15, which are respectively forwardly and rearwardly adjustably- ,fas tened to the rear portions of the bars 2 by bolts 16 which extend through slots provided V gitudinally, one in each bar 2 andldesignatedby 17. l v I A crank shaft 18 extends transversely through the slots 17 and is, rota tably,mount ed in! the bearing members 15. The crank shaft 18 has two oppositely disposed cranks 19, whichare'adaptedto be. respectively enlgaged and turned the feet of the person operating the apparatus. Iltespectively rotatable on the cranks19 are .stirr'ups 2O through which the operator inserts his feet Secured rigidly on the ends of the crankshaft 18. are two bevel gear wheels 21, which respectively mesh with two bevel gear wheels which are respectively splined to the shafts 12 so asto slide thereon and rotate therewith.

The bolts 16 are loosened and the bearing members 15 are then adjusted on the bars 2 to position the: crankshaft 18 to suit the height of the person. who, isto operate "the apparatus. The bolts '16are then tightened...

' In the operation of the apparatus,the person disposes himself-face down with -his breast nponthe board 5, his'hands grasping the handhold 6, and his feet in thestirrups 20, as-shown in dotted lines in Fig. 2. If the operator now with his feet rotates the crank shaft 18. in a clock wisev direction, as. viewed in Fig. 2, the paddle wheels 7 will be rotatedin a like direction :byineans of the gearwheels 21 and 22, shafts 12, gear wheels 11 and 10 and shafts 8, thereby propellingthe apparatus, and with it the. per-- son, in a forward'direction. Theoperator ill reversing the direction of rotation of the crankshaft can propel the apparatus backwardly. I a

The distribution of the weight of the person and the buoyant material is such that during the operation of the apparatus, and when the personis resting, thefloats will'remain substantially horizontal.

ture shown and described, as modifications, within the scope of'the appended claims,

maybe made-without departing from the spirit of my invention.

, What I claim is p '1. In a swimming apparatus, a buoyant frame comprising two spaced'apart floats, a body support between and connecting said floats, and two rearwardly extending bars, two propelling wheels rotatably mounted on said floats respectively, two bearing members respectively forwardly and'rearwardly adjustable on said bars, a crank shaft rotatably mounted in said bearing members and 'l'iaving two "oppositely disposed cranks adapted to 'be V respectively engaged and turned by the feet of a person lying on said body support, and means actuated by said shaft for rotating said propelling wheels.

2. Ina. swimming apparatus, a buoyant support adapted to support the body :of a.

person, two propelling wheels rotatably mounted on said su ort two bearin 'menn bers "forwardly and rearwardly' adjustable on said supper-ha transverse shaft rotatably mounted on said bearing members and having two oppositely disposed cranksadapted toibe respectively engaged and turned by the feet of the person. two bevel gears secured to and rotatable with said shaft, two longitudinal rotary shafts mounted respectively in said bearingmembers and longitudinally slidable therein, two bevel gears respectively secured to Said longitudinal shafts and adjustable longitudinally thereon and respectively m'eshingwith the first named gears, and means actuated by said longitudinal shafts for respectively rotating said propelling wheels.

3. In a swimmingapparatus, two floats, a body 'supporti'n member intermediate of and sup iorted,bysaidfloats, two rearwardly extending bars scc'ured to said floats,- two bearing; members respectively forwardly and rea'rwardly" adjustable on said bars, a

transverse shaft rotatable in said bearing members and having two oppositely disposedcranks adapted to beuengaged' and turned by the feet of a person lying on said body supporting member, two propelling wheels respectively carried by said floats, and means actuated by said shaft for rotating said propelling wheels. i

In swimming appa atus, two floats, a
