CONVERTIBLE SLED AND BOAT.

Specification of Letters l atent.

Patented Jan. 4, 1910.

Application filed September 3, 1909. Serial R0. 516.07

Be it known that we, Joser Exsno and Enus l'lxnnomitizens of the United Statesof America residing at Erie, in the county of Red Lake and State of Minnesota, have in- 1 vented certain new and useful Improvei l i ll'l .'lll in Convertible Sleds and Boats, of which the following is a specification.

The object of this invention is to provide a construction of boat involving suitable propelling means, and associated with a desirable arrangement of runners and guiding devices, whereby the boat may be converted into a sled to facil tate travel over snow or ice.

The invention involves especially the mounting of the runners and the mechanism for actuating the same whereby they may be u out of operative position according to whether or not the boat is to travel through water or form the body of a sled.

For a full understanding of the invention, reference is to be had to the following detail description and to the accompanying drawings, in which Figure 1 is a side elevation of a convertible boat and .ll'tl embodying the invention; Fig. 2 is a top plan view; Fig. 3 is a transversesect ion taken about on the line 3-3 of Fig. 1; Fig. 4 is a transverse section taken about on the line 4% of Fig. 1, and Fig. 5 is a detail sectional view showing more. clearly the adjustable mounting of the guiding disks or heelslocated at the front and rear extremitie of the machine.

Throagln ut the l'ollowing detail description and on the several figures of the drawings similar parts are referred to by like. reference character-z. 1

Specifically describing the invention and the drawings 1 denotes a boat of any suitable coictruction and the rear portion of which is formed at the bottom v-ith a recess '2 providing a compartnu-nt in v hich the upper portion of a s rew propeller E S isarranged. Th propeller 3 is mounted upon a suitable propeller shaft, which su 'iport'ed in bearing-r l adjacent tothe front '2, the front end of thc litntn'li tkliai l projecting through the front wall of tin recess 1 into the boat and having mounted thereon a gear which any u table i-ianually or mo or drivcn power mcchani-m may be connected i i l l l I 5 with i 1 in order to propel the boat through the water.

Beneath the boat 1 are mounted spaced runners (3 of any suitable type, said runners being provided at their front ends with two toothed segments 7' rigidly attached to the runners in any substantial way. The teeth of the segments 7 arein mesh with toothed pinions 25 mounted on the opposite ends of shafts 9 supported transversely in the boat.

The opposite ends of the shafts 9 pass through stalling boxes 10 at opposite sides of the boat 1 and project from opposite sides of the boat in such a manner as to receive thereon the exterior pinions 8 that mesh with the segments 7. Links 11 connect the projecting ends of the shafts 9 with the runners 6 as shown at 12 and said shai'ts 9 are adapted to be rotated by means of an operating shaft 13 having a turning wheel or handle H at its upper end. the lower end of thrshaft 13 has a gear 15 thereon meshing with a bevel gear 16 on a longitudinal shaft 17 supported in bearings inside of the boat. On the front and rear ends of the shaft 17 are worms 18 which mesh with worm gears 19 keyed or secured to the shafts 9. At the rear endsthereof the runners 6 are provided with rigid segment brackets 20 with which grooved wheels 21 engage in a manner somewhat similar to the cooperation of the pinions 5 with the toothed segments 7 at the front portions of the runners. The wheels 21 are supported upon a suitable shaft which is connected at its end with the rear ends of the runners by means of links 23.

In order to direct the movement of the boat or sled it is contemplated to provide at the front and rear ends thereof guiding wheels "it in the form of sharp edged disks carried by bifurcated standards 25, the upper end of which are supported rotatably in pivoted arm-a 2(3- pivotally connected with ;the opposite extremities of the boat. The

wheels 3] are adapted to be. raised and lowered by means of a hand lcver 27 located at any convenient place intermediate of the ends of the boat, said lever being connected withbcll crank levers 25, the latter being in turn connected by links with the arms 26.

\Vhen the boat 1 is to be propelled through the water the hand wheel 14 is turned so as to rotate the pinions S and cause th segments 7 to move rtairwardl thereby ti"' .'.ii

ing the runners with res act to the boat and so that they do not inter ere with the movement of the latter through the water. then the machine is to travel over snow or ice, however, it is desirable that the runners 6 be adjusted so that they assume the position shown in Fig. 1 and whereb the boat is supported thereon and props led under such The standards 25 are freely rotatable on the arms 26 and vertical adjustmenhof said standards to vary the operative position of the wheels 24 with respect to the runners 6 may be effected bv means of a nut 29 on the upper end of eac standard and which has threaded connection therewith.

Having thus described the invention, what is claimed as new is:

1, In a convertible sled and boat, the comhination of a hoat-, spaced runners beneath the same, toothed segments carried by said runners, means connecting the runners with the boat in a pivotal manner, pinions mounted on the boat to engage the toothed segments for moving the runners into and out of operative position, and means for operating said pinions.

2. In a convertible sled and boat, the combination of i1 boat, a pair of snnced unners beneath the same, links pivotaly connecting
