Application filed August so, 1920. Serial at. 406,941.

To all whom t may concern:

Be it known that I, hLlORRIS HANNA, a citizen of the United States'of America, and a resident of New York, county of New York andState of New York, haveinvented certain new and useful Improve ments in Toy Boats, .of which the following is afull and clear specification.

The object of this invention is to provide a simple toy boat provided with means for propelling it, the propelling means belng adapted to be wound up by hand or a suitable hand. implement, as more fully hereinafter set forth.

In the drawing- 7 Fig. 1 is a perspective view of a toy boat constructed in accordance with my invention, the propelling arrangement being adapted for marine propellers;

Fig. 2 is a similar view, foreshortened, showing the invention applied'to an aerial propeller type of boat.

Referring to Fig. 1, a designates the hull of the boat, which may be of any suitable construction and proportions and which in the present instance is shown as constructed of a single piece of wood, properly shaped or carved. Fastened to the stern of the boat, upon its upper side, is a bar 5, whose ends project outwardly beyond the S1065 of the hull and are bent upwardly, the extreme ber hand f, each propeller-shaft being provided with an open eye 6 to enable the band to be readily attached thereto. The ends of the bands are attached to eyes (Z and e by being simply slipped .thereinto' so that, it will be observed, the bands may be readily removed from the eyes. 4

To charge the propeller mechanism of the boat with power, it is simply necessary to rotate the propellers in the opposite direction to thereby twist the rubber bands and put them under atorsional strain, whereby when the propellers are released the tendency of the bands to untwist will rotate the propellers in the opposite direction and thus propel the boat. The bands may be twisted directly by hand or through the medium of a hand operated twisting appliance which will twist the'bands with equal tension, to thereby ensure an equal development of power in the two propellers and thus ensure a straightforward movement of the boat. lVhile it is desirable to thus wind the bands to an equal tension to thereby drive the boat in a straight line, it is one of the advantages of my device that the bandsmay be twisted to an unequal tension where it is desired that the boat shall be propelled in a curved path. The driving of the boat in a straight line by equally tensioning the bands is ensured by employing a pair of propellers and arranging them symmetrically on the hulk-that is, an equal distance from the longitudinal center line of the hull. It will be observed further that by arranging the rubber bands at a point above the upper surface of the hull they will be suspended in a plane above the surface of the water so as to prevent the bands dragging in the water and thus retarding the boa When the bands are twisted by means of hand implement, it will be understood that the forward ends of the bands are removed from the eyes (Z and engaged with the hooks of the twisting implement; and then after the bands are equally twisted to the desired degree the looped forward ends are slipped out of the twisterhooks and into the eyes (Z, immediate rotation of the propellers being prevented by grasping the hull at the rear end thereof in such manner that the hand will prevent the propellers rotating. When the boat is placed in the water and the hand is removed, the propellers will immediately begin rotation and continue to rotate until the bands are completely untensioned.

It will be understood that it is within the broader spirit of my invention to employ but a single propeller and propellerband arranged over the longitudinal center of the boat; and it will be further understood that, as shown in Fig. 2, I

may extend the propeller-supports high enough from the deck of the boat to employ air propellers instead of the marine propellers shown in Fig. 1.

It will be observed further that by employing power means located above the surface of the deck of the boat, I am enabled to employ a marine propeller of the semiembodiment having been specifically described, what is claimed asnew is:

A toy boat comprising a hull, propellers mounted at one end of said hull having forwardlyextending shafts formed into hooks at their free ends, supports for said propeller-shafts extending upwardly and outwardly from the hull, whereby the shafts are supported in a plane abovethe top surface of the hull and above the Water-line of the boat, and a separate driving means for each of said propellers embodying an elastic band adapted to be twisted under tension andwhich extends substantially the length of the hull and secured at its ends to the front end of the hull above the waterline and propeller-shaft respectively.

In testimony whereof I hereunto afiix my signature. 1

MORRIS HANNA.
