Definitions

  • the present invention has for its object a swimming apparatus comprising a casing provided with floats and with a propeller which is so arranged as to receive its rotary movement by the simultaneous action exerted by the hands and feet of the swimmer on two pairs of opposite cranks. so as to allow of using in the best conditions the unbending action of the limbs of the swimmer.
  • the 7 driving crank shafts which pass through the floating casing at its ends, are connected together by means of toothed wheels and of a counter-shaft enclosed in the said casing and actuate at a suitably multiplied speed the shaft of the propeller.
  • the driving crank shafts are each constituted by two tubes of elliptical section sliding in each other so as to allow of folding the apparatus for reducing to the minimum the space it occupies and placing it in a case, when it is not in use, and in the developed position, of adjusting its length according to the stature of the swimmer.
  • crank shafts are mounted in ball bearings and are enclosed in fluid-tight chambers, filled with oil and formed at the front and rear ends of the floating casing.
  • Fig. 1 is a front view of a first form of construction.
  • Fig. 2 is a plan View.
  • Fig. 3 is an end View.
  • Fig. at is a horizontal section, on an en- 4 larged scale, showing the front end of the apparatus.
  • Fig. 5 is a cross vertical section made according to line 5-5 of Fig. 4:.
  • Fig. 6 is a side view of a modification.
  • ig. 8 is a front view of the front floats.
  • Figs. 9 and 9 are a partial horizontal section on an enlarged scale.
  • Fig. 10 is a partial longitudinal vertical section of the front of the casing or hull, mule according to line 10-10 of Fig. 9.
  • Fig. 11 is a cross vertical section made according to line 11-11 of Fig. 10.
  • the swimming apparatus forming the subject-matter of the present invention comprises a casing or hull which is essentially constituted by two sheaths 1 and 2 of elliptical cross section fitting and capable of sliding with slight friction in each other.
  • the tubular sheath 1 which covers the sheath 2 on an adjustable portion of its length, is slotted, as indicated at 3 and rigidly secured on the sheath 2 by means of a collar 4 provided with a tightening bolt 5.
  • the sheath 1 is closed, at its front end. by a cap 6 and carries a transverse shaft 8 mounted in ball-bearings 7; on this shaft 8 are rigidly secured, on the one hand two cranks 9 having a handle 10 and adapted to be actuated by the hands of the swimmer and. on the other hand, a bevel wheel 11.
  • the sheath 2 tern'iinates and is closed, at the rear end of the casing or hull by a conical part 12 within which is secured a ballbearing 13 carrying the shaft 14: of the propeller 15 provided with a drivin pinion 16.
  • This sheath 2 is also provided, as the sheath 1., with a transverse shaft 17 parallel to the shaft 8 rotating in ball-bearings 18 and on which are rigidly secured two cranks 19 having pedals 20 adapted to be actuated by the feet of the swimmer and arranged opposite the cranks 9, as clearly shown in Figs.
  • This trunnion 2% is connected, by a Cardan joint 26, to a tube 27 of oval cross section, which fits and slides in another tube 28 of similar shape, and connected, by a Cardan joint 29, to a second trunnion 30 mounted in a ball-bearing 31 secured in the tubular sheath 1 of the casing or hull and carrying a pinion 32 gearing with the toothed wheel 11 of the driving shaft 8 actuated by the hands of the swimmer.
  • the buoyancy and stability of the above described apparatus are ensured by two floats 32 arranged at the front and by a third float 33 arranged at the rear of the apparatus.
  • the front floats 32 are carried at the end of a bracket 3% which. rigid with a clamping collar 34 allowing to adjust the position on the sheath 1 of the said bracket according to the stature of the swimmer, is so shaped as to allow the latter to easily place himself between the floats and to constitute a sup port for the swimmer; the said bracket extending on the shoulder-blades and par tially surrounding the shoulders whilst leaving to the arms their complete freedom of movement.
  • the rear float 33 is carried by the sheath 2 of the casing or hull and disposed between. the legs of the swimmer in such a manner that it does not hinder his movements, in any way whatever.
  • the three floats are constituted by air pockets which, when the apparatus is not in use, are caused to subside for allowing the said folded up apparatus to be placed in a case.
  • the two tubular sheaths l and 2 of the casing or hull are respectively provided, at a certain point of their length, with a partition 3536 limiting at the ends of these tubular sheaths, the chambers 37-38 which are hermetically closed and filled with oil so as to ensure the constant lubrication of the driving shafts 8 and 17 and of the transmission members which enclosed in the said, chambers sheltered from cont ct with the water.
  • the front chamber 37 in which is mounted the shaft 8 is provided, at its base, with an opening in which is fitted and this suitably secured a case l gear case is enclosed a multiplying gearing con prising, secured on an axis ethaspurpinion 42 and a toothed wheel 43 which are respectively in engagement with a toothed wheel 44 integral with the shaft 30 and with a pinion 45 secured on the end of a Sllllt l6 mounted in a ball-bearin 47 and connected by a Gardan joint 48 to an inclined shaft all) pivoted, by a Cal-clan joint 50, to the shaft ll of the propeller 15 journalled in a support 51 secured in the sheath 1 of the casing or hull as clearly een in F g. 6.
  • the ball-beef 31 and 25 within which rotate the she 30 and 24 are surrounded by a cork packing or lining 54.
  • the floats ensuring the bnoyan ed tuistability of the apparatus and of .ne 5- vimmer who takes his place on the latter, are constituted by three air pockets two o t 32 are arranged at the front and the of 33 at the rear.
  • the front end of the casingor hull is provided with wooden elements and 56 which present, at the front, a sharp edge and are respectively secured on the bottom (3 of the sheath 1 and on the front face of the gear case ell) enclosing the speed multiplying gearing.
  • the rear tloat 33 is farther away from the sheath 2 than the floats 32 from the sheath 1 so that the apparatus takes in the water the inclined position shown in Fig. 6 and that the swimmer using this apparatus immersed in such a manner that only the head and shoulders are above the level of the water; this also contributes, with the position given to the propeller, to the facility of advance of the apparatus.
  • the front cranks 9 are provided with handles which are constituted by knobs 10 arranged in such a manner that the palm of the hand which grips them is vertically directed.
  • the front floats 32 are each internally provided with two tubular cross pieces; in one of these cross pieces 56 fits the vertical branch of a bent arm 57 which is connected to the second cross piece 58 by an inclined bar 58 pivoted to the said cross piece 58 and which fits, by means of a collar 59 at each end of a U-shaped support 34.
  • This Ushaped support 3% is so shaped, as clearly seen in Fig. 1, as to pass in front of the shoulders of the swimmer and to support, in its middle part, the upper part of the thorax of the latter which, on the other hand, bears on an apron 60, made of rubberized fabric, secured to the said collar and at a suitable point of the sheath 1 (F ig. 7
