FORDHAM coorna MAHONY', OF NEW YORK; N.'Y., AND AUSTIN MILES HOPEY, 1a., F

, WEEHAWKEN,

NEW JERSEY Patented Dec. 1, 1908.

To all whom it may concern: I f

Be it known that we, FoRorrAM @Coornn and AUSTI MILEKI-IOPEY, Jrn, residing at \Veehawken, in {the county of'I-Iudson and" State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in .Ice-Boats, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof. v

Our invention relatestoimprovements in vehicles adapted to bepropelledalongice or hard snow and commonly called ice boats; and an object of our invention is to provide a vehicle of the class just described which will prove simple in construction, comparatively cheap in manufacture and readily.

controllable and dirigible in use.

Another object of our invention .isto provide an ice boat which may be propelled by a young boy using his legs.

A further object of our invention is to provide an ice boat in which the propellers may in case of need be used as a brake.

Other features of our invention willbe alluded to in the description and claims which follow.

In the drawings illustrating the principle of our invention and the best mode now known to us of applying that principle, Figure l is a side elevation .of our new ice boat; Fig. 2 is a central vertical longitudinal section; Fig. 3is a plan view;;Fig. ,4 is a sectional detail showing the devices'for raising and lowering the propellers; and Fig. 5 is a detail of the rudder and its mounting. V

The shell or hull a is mounted upon a pair of runners b and carries at itsfront. end a hood 0 and at its rear a seat (Z. Between" the sides of the shell near its middle is mounted a footboard c which serves as a rest for the feet of the operator or driver and also as a fender to protect his legs a ainst the current of cold air and against drifting snow. As shown in Figs. 2 and 3, the hood 0 is formed with a central longitudinal slot f and each of its sides is supported by suitable braces f, while transversebraces 9 extend between the sides of the shell.

J ournaled in rearof thefootboard e and suitably disposed with regard to the seat cl:

vided with pedals and cliainconn ectetl is atransverseshaft' h uponl'whioh is trally V mounted the driving s rocket z' pro'-j with the sprocket 76 which is fast upon the i propeller-shaft m. Mountedfast upon the latter on each 'side of the sprocket' lcjis a toothed propeller at but the numhejrLof pellersmay bevaried tomeet the exi encies formed;

of use. Eaoh side" ofthe shell a is with a slot o'through which projects an'en'd of the propeller-shaft m; and each end of the latter i's carried by and journal'ed in the lower end" of an elbow-lever p the upper end,

of which is" formed'withlthef hand gras'p (1. The elbow-levers 29 are each fulcrumed upon an end of the transverse shaftr and extend upwardly between the side of the seat 03 and a toothed bar 8 fastened thereto (Fig. 4).

When the elbow levers p are engaged in the notches t, the propeller-shaft m is raised so that the teeth of the propellers do not touch the ice (or the crust of the snow) and the driver, resting his feet upon the footboard 6, may coast. By throwing the elbowlevers p to thelast notch in rear, the driver, back-pedaling at the same time, may use the propellers as a brake. In the position of the elbow-levers intermediate these extreme positions, the propellers will be engaged more or less with the'ice for the purpose of driving the. ice boat at the will of the operator. I

U Extending transversely between the sides of the shell (6 at its forward part is a spring or yielding rudder-bar a through which projects at its center the rudder-post v on the lower end of which is mounted the rudder w and on the upper end of which is mounted the transverse pin 0: by which the forked end of the steering-rod 3 is pivotally secured to the rudder-post v. The upper end of the steering-rod g is provided with a suitable grasp, as the hand-wheele; By turning the adjusting nuts 2, after loosening the lockingnuts 3, the position of the rudder w may be changed relatively to the rudder-bar u. But the nuts 2 are so adjusted as to allow the rudder-post 'v to turn readily, as will be understood. I

The longitudinal slot f in the hood 0 permits the steering-rod 3/ to be thrown to the front (see dotted lines, Fig. 2) and to be then used for hauling the ice boat should occasion require.

The rudder-bar it being flexible, it allows the rudder w to give or yield in case it meets inequalities in the ice.

We claim:

1. In an ice-boat, the combination with a shell having walls provided with runners, of a seat for the driver suitably disposed in said shell; a foot-board mounted transversely of said shell between said walls; a foot-operated wheel provided with pedals and arranged below said seat and inthe rear of said foot-board, said foot-board serving to shield the legs of the driver while operating said wheel; a propeller shaft driven by said wheel, said shaft being readily movable by the driver towards and away from the ice; a propelling device mounted on said shaft; and mechanism for moving said device free from the ice to allow the boat to coast, said last named mechanism being under the control of the driver and readily operated by him.

2. In an ice boat, the combination with the shell, of a yielding transverse rudder bar secured at each end to a side of said shell; a

rudder-postmountcd free to turn in said rudder-bar; a rudder upon the lower end of said rudder post; and a steering rod connected with said rudder post, said. yielding rudder-bar holding the rudder down upon the ice and allowing the rudder to yield on meeting inequalities in the surface of the ice.

3. In an ice boat, the combination with the shell and steering mechanism therefor, said shell being formed with a longitudinal slot. of a. steering rod pivotally connected with said mechanism and tree to be swung through said slot in front of the boat. whereby said rod may be used as a draft device to haul the boat.

In witness whereof we have hereunto set our hands at said New York city in the presence of the two undersigned witnesses this twenty-fifth day of October,- [907.
