May 28, 1935 TOY Filed Jan. 21, 1955 2 Sheets-Sheet 2 Inventov Attomey Patented May 28, 1935 mm STATES arms" I 1 Claim.

This invention relates to a toy boat and aims to provide a boat which simulates the movement of a fish in the water and the object of the invention resides in the provision of a spring motor actuated mechanism within the body to oscillate a propeller in imitation of a fish tail.

Further objects of the invention are to provide a toy boat of this character which is exceedingly simple in its construction, inexpensive to manufacture, easy to manipulate, and thoroughly reliable for entertaining children. 7

With the foregoing and other objects in view the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompanying drawings, wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations, and modifications may be resorted to without departing from the spirit of the claim hereunto appended.

In the drawings wherein like characters designate like parts throughout the several views:

Figure 1 is a side elevation of the device in accordance with the present invention.

Figure 2 is a detailed vertical section thereof.

Figure 3 is a detailed horizontal section taken substantially on line 3-3of Figure 1.

Figure 4 is an enlarged fragmentary horizontal section through the escapement mechanism.

Figure 5 is an enlarged perspective View of the forward end of the propeller attached to the propeller shaft.

Referring to the drawings in detail, it will be seen that the numeral 6 denotes a closed hollow body of the hull of the toy boat formed in simulation of the body of a fish. In the hollow body is a frame consisting of a flat top plate 1 and a fiat bottom plate 8 connected together by the vertical end rails 9. The body 6 is preferably formed of metal and the bottom plate 8 of the frame is anchored to the bottom of the body 6 preferably by welding or brazing.

A vertical stem H! has the lower end thereof journaled in the bottom plate 8 of the frame as at l I, and an intermediate portion of the stem is journaled in the top plate 7 while the upper end of the stem l0 extends through an opening I2 in the body and has a winding piece l3 on the projecting end thereof. The stem I0 is caused to rotate by a spring motor l4 carried thereon. The stem I!) also has a relatively large gear wheel l5 secured thereto which meshes with the pinion gear I6 fixed to the auxiliary stem IT. The ends of the auxiliary stem I! are rotatably mounted in the upper plate 1 and the lower plate 8 respectively of the frame. There is also an escapement gear l8 fixed to the auxiliary stem I1 below the pinion gear 16.

The escapement mechanism includes a rockable 5 arm is having the upper end thereof rockably mounted in the upper plate 1 of the frame, while the lower end is rockably mounted in the lower plate 3 of the frame. The conventional or usual rocking escapement pawls 20 extend from the op- 10 posite sides of the rocking arm I 9 and alternately engage with the teeth of the escapement gear 18 to impart a rocking motion to the arm I9.

Above the water line 35, the rear end of the hollow body 6 is formed with a slot 20 disposed in a transverse direction. One end of an oscillating propeller shaft 2! extends through the slot and coupled to the projecting end of'the propeller shaft by means of a pin 22 is a relatively fiat flexible propeller 23 that simulates the tail of a fish in configuration. The body portion of the fish tail propeller is preferably formed of rubber although it may be made of any desired flexible material. The inner end of the oscillating propeller shaft 2| is fixed to the rocking arm l 9 as at 24 so that when the arm rocks an oscillating motion willbe imparted to the propeller shaft and translated to the fish tail propeller .23. v To prevent water from splashing into the body 6 from the oscillations of the propeller there is a bridge wall 25 under the slot 20, the opposite edges of which are secured to the opposed walls of the body 6. Above the slot there is another bridge wall 26 mounted in a manner similar to the lower bridge wall 25 and for the same purpose. The bridge wall 25 flares outwardly and downwardly so that Water may drain backwardly to the rear of the body and out through the slot.

A rudder 27 is fixed as at 28 to the lower end of the steering pin 29 rotatable in an opening 30 in the body 6.

From the above detailed description it will be obvious that when the spring motor I4 is wound and released the said motor will cause an oscillating movement to be imparted to thetail propeller 23 so that when the toy is in the water it will be propelled forwardly in simulation to the swimming movement of a fish.

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

A toy boat comprising a closed hollow body, said body being formed with a slot at the rear end above the water line, a plate secured on the inner side of the lower portion of said body, a

pair of spaced upstanding supports fixed to said V plate, a second plate secured to the free end of said support, a rotatably mounted stem in said plate extending upwardly through the upper portion of said body and having a handle on the 5 free end thereof, a spring motor secured to said stem, between said plates, a large gear fixed to said spring motor, a shaft rotatably mounted between said plates adjacent said stem, a pinion gear on said shaft, in mesh with the motor gear,

an escapement gear on said shaft, an escapement pallet extending through the slots in the body and having a tail propeller secured to the outer end thereof whereby the tail propeller is directly actuated from the escapement gear, and a bridge wall across the rear end of the body under the slot to prevent water from entering the body.

YUZABUBO HIROSE.
