SPECIFICATION forming part of Letters Patent No. 551,367, dated December 17, 1895.

Application tiled Januaryk 9, 1895. Serial No. 534,286. (No model.)

To Z-Z whom t may concern:

Be it known that I, GEORGE F. CREMER, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in lVater-Bicycles, of which the following is a specification.

My invention relates to improvements in marine velocipedes, its object being to provide an improved consti-notion thereof and simple, easily-operated means for steering and propelling the same.

To this end my invention consists in providing a pair of similar hulls or shells arranged parallel With each other and having a bicycle-frame secured intermediate thereof. The vessel is driven by means of a screw-propeller operatively connected with the footpedals by means of suitable gearing, and each hull is preferably provided with a rudder, which is connected with and actuated by the handle-bar. The cross-bars connecting the two hulls or shells and supporting the frame and propelling connections are provided with means for adjustment longitudinally of the shells and also for the adjustment of the hulls toward and from each other. The propellershaft is supported by means of verticallyadjustable hangers depending from the crossbars, the hangers being preferably provided with ball-bearings, in which the shaft turns. The propeller-shaft is also adapted to be adj usted longitudinally to compensate for different-sized gearing.

My invention further consists in the improved features of construction hereinafter more particularly described, and pointed out in the claims.

In the accompanying drawi1igs,for1ning part of this specification, Figure i is a side elevation of my machine. Fig. 2 is a top elevation illustrating the steering and propelling attachments and the adjustable connections between the hulls and cross-bars. Fig. 3 is a cross-section of the same, taken on line o: :c of Fig. 2. Fig. 4 is a seetionaldetail of one of the rear bearings for the propeller-shaft, and Fig. 5 is a similar view of the forward bearing. Fig. 6 is a detail of the hanger for supporting the rear bearing for the propellershaft. Fig. '7 is a detail f the bevel-gear, sprocket and pinion at the front of the machine, by which power is transmitted to the propeller.

Fig. S is a plan view of the supporting-plate for the gear and sprocket, secured to the under side of the front cross-bar. Fig. 9 is a detail of one of the end bearings for the driving-shaft. Fig. l0 is a longitudinal section of the handle-bar standard, the Linner inclosing tube being broken away to show the inclosed bar, and Fig. Il is a detail of one of the clamps for securing the tube upon the bar.

In the drawings, A represents the bicycleframe provided with the necessary seat, handle-bar, pedals, cbc. This frame is supported upon the cross-bars and i3, which connect the hulls 4 and 5. These hulls are preferably of the form shown in the drawings and are shown lled With air-tight cans, so that in case of puncture the ext-ire hull will not become illed with Water. Secured to the tops of the hulls are the plates G, provided with longitudinal slots 7, passing through which slots and similar slots S in the

cross-bars

2, 3 and 9 are bolts l() to provide for the adjustment of the cross-bars longitudially of the hulls and for the adjustment of the hulls toward and from each other.

Running from the sprocket ll upon the pedal-shaft l2 of the frame A to the sprocket 13, mounted upon the driving-shaft 14, is the sprocket-chain I5. The shaft la is journaled in ball-bearings 1G in the doWnWardly-depending lugs 17 of the plate IS, the plate 1S being secured to the under side of the cross-bar 2 and projecting rearwardly from the same, forming support for the rod 19 of the bicycleframe. Meshing with the bevel-gear 20, also mounted upon the driving-shaft, is the pinion 2l, connected with the screw 22 at the rear of the machine by means of the shaft 23. The propeller-shaft 23 is supported in the ballbearings 2i, 25 and 26, the bearing 24C being supported by means of the hanger 27, connected to the plate 18, and the bearings 25 and 26 being similarly supported from the cross-bars 3 and 9 by the hangers 28 and 29. The hanger 27, as shown in Fig. '7, passes through the slot G3 in the rearwardly-extending arm (Si of the plate I8, and is connected upon the opposite side of the slot to the' rod 19 of the bicycle-frame. This rod i9 is provided witli a turnbuckle 65, 'by which its length may be varied in the adjustment of the parts.

IOC

rtherewith.

collar 4l, formed by the bottom of the hanger In the bearing 25 r(see Fig.. 4) the propellershaft is inclosed bythe tube 30, preferably brazed thereto. The end pieces 31 and 32 of the bearing and the inner block 33'iit closely to the tube 30 and turn with it in the rotation of the shaft. i Between the block 33 and the collar 34 are placed the balls 35 of the bearing. The collar 34 is pivotally connected to the hanger 29, projecting downward from the crosssbar. The different parts yof the'bearing are held in contact by means of the lug 3G'upon one end of the tube engaging one end of the bearing and the nut 37 screw-threaded In the bearing 24 (see I `ig.5) the end pieces f 3S and 39 are secured to the shaft and revolve The inner collar 40fand the outer 27, remain stationary in the turning of the shaft and the other parts ofthe bearing bean against them. The balls 42 of the bearing lare placed between the fixed and turning parts. The pinionv 21 and the collar 43 separating the pinion from the bearing are also secured to the shaft rby means of the spline 44. VThe different parts ofthe bearing and the pinion are held in contact by means of the nut 45, screw-tineaded rupon the shaft and engaging one end of the bearing, and the nut 4G also screw-threaded upon the shaftV and abutting against y,the pinion. The shaft is made in two pieces, the part 47, carrying the bearing and pinion, fitting into the body of the shaft so as to be easily removed therefrom for the purpose of removing the bearing.

f -In Fig. 9 is shown a det-ail of one of the bearings 16 for the driving-shaft I4.' In this Aform of bearing the parts 43 and 49 and the encircling collar formed by the end of the lug I7 remain stationary, and the shaft revolves therein upon the balls 50, traveling in the groove 51.

The handle-bar standard of the bicycle-.

frame extends down through the cross-bar 2 and has secured to its lower end the crosspiece 53. The ends of this cross-piece are connected with the tillers 54 of the rudders 55 by means of the ropes or wires 56 in such manner that they can both be operated simultaneously by the turning of the handle-bar.

I show in Fig. l0 an improved form of handle-bar standard for use with my machine. In this form the standard is made in two sections 57 and 58, fitting closelyinto the ends of the tube 59, which in turn is adapted to turn inside the hollow sleeve or case 60 upon the interposed ball-bearings 6l. The ends of the tube 59 are slitted, so that they will give, and are clamped upon the ends of the standards by means of the clamps 62. The clamps 62 also hold the tube 59 from vertical movement in the sleeve 60. Vith this form of standard the bar turns freely in the outer sleeve, and either section ,of the bar can be independently adjusted by the loosening of the clamp.

IVhile I show in the drawings and prefer to use a steering-rudder hinged to the rear of each of the hulls, it is evident that this arrangement can be modifiedand one rudder instead be placed intermediate of the rear of the hulls.

Secured to the'tops of the hulls are the footrests 63 to be used in mounting to prevent breaking through the tops of the hulls.

yBy means of the adjustable connections between the cross-bars and the hulls the bars rmay be adjusted longitudinally of the hulls and the hulls adjusted toward and from each other at will. The propeller also may be raisedfand lowered by means of the nuts 64 upon the ends of the hangers supporting the propeller-shaft.

It will be evident that on. account of the adj ustability of the forward hanger inthe slot 63 and of the cross-bars connecting the hulls,

which serve as longitudinally-'adjustable sup-y ports for the other two hangers, the propellershaft can be adjusted longitudinally to compensate for different-sizedl gearing upon the counter-shaft when different relative speed is desired.
