C. R. BUCHET TOY SPEED BOAT Filed April 2, 1927 [NVENTOR AT ORNEY Patented Sept. 25, 1928.



Application filed April 2, 1927. Serial No. 180,537.

This invention relates'to toy boats especially adapted to be used on the shallow lakes and streams in amusement and recreation parks,

and occupied and guided by children in the pursuit of pleasure and is designed to be provided with a suitable steering gear an a propeller driven by an electric motor installed in the boat.

The main object of the invention resides in the efficient and novel manner of the mounting of the motorand the propeller shaft which extends outwardly through the bottom of the boat in such manner that the water will not work into the motor and damage same.

Another object of the invention is to provide a novel flexible means for coupling the propeller shaft to the motor shaft.

The above and other objects of the invention will be more fully described in the following specification and exemplified in the accompanying drawings, in which:

Figure 1 represents a longitudinal section through a boat embodying the features of the invention.

Figure 2 is an enlarged longitudinal section through a portion of the shaft mounting illustrating the flexible coupling between the motor shaft and the propeller shaft.

Figure 3 is a transverse section through the same taken on the line 33 of Figure 2.

In carrying out the invention, 5 represents a boat which may be of any desired model and formed of any desired material and is provided with a front seat 6 and a rear seat 7. v

The steering apparatus is shown in a conventional manner and comprises a rudder 8 which is located at the stern of the boat and is provided with a stem or shaft 9 which is journaled in a bearing 10 secured tothe bottom of the boat. A lever 11 is secured to the top of stem 9, which extends into the boat,

. and pivoted to the end of said lever is one end of a rod 12. The other end of the rod 12 extends forwardly and is pivoted to'a crank 13 which is secured to a shaft '14, journaled in a bearing 15 secured to the boat and secured to the upper end of said shaft is a steering wheel 16 which is located adjacent the seat 6 upon which the navigator sits.

Mounted in the bottom of the boat is a standard 17 which is provided with a flange l8 resting on the boats bottom and secured thereto in any suitable manner as by means of the bolts or lag screws 19.

The standard 17 comprises a casing in the shape of a hollow sleeve 20 at its forward end and a. hollow stem 21 to its rearward end, i

both of which are inclined downwardly as they extend rearwardly, the stem passing outwardly into the water through an aperture 22 in the bottom of the boat, and in order that water may not leak through said aperture, a suitable packing gasket 23 is interposed between the flange 18 and the boats bottom as shown in Figure 1 of the drawings.

Secured to the forward end of the casing 20 is an electric motor 24 which is also inclined in the same manner as the casing, and is adapted to be operated in the usual manner by it storage battery, not shown, located-in the mat.

The motor shaft 25 projects into the casing 20, and has secured to its end a flexible sleeve 26 by means of a cotter pin 27, and is preferably composed of canvas and rubber, similar to that of a hose.

Socketed into the opposite end of sleeve 26 is one end of the propeller shaft 28 which is secured thereto by means of the cotter pin 29.

The shaft 28 is journaled in suitable bearings in the stem 21 and is incased thereby and has secured to its rear end the propeller 30.

The boat is provided with the usual false bottom 31 under which is located all of the working parts with the except-ion of the motor which is located under the front seat 6 as shown. 7

By the above recited construction it will be obvious that no expensive and frictional resisting packing will be necessary at the rear end of shaft 28, due to the incline of same, which prevents the water from reaching the motor as the motor is located above the water line as indicated at the line a-a, and that an eflicient and economical flexible coupling has been provided to form the juncture between the motor'and propeller shaft as shown in Figure 2, the relatively thick, flexible sleeve 26normally maintains the adjacent shaft ends slightly spaced apart thus providing for neutralizing vibration resulting from. rapid propulsion of the propeller and yet transmitting power in a smooth, dependable manner.

Having thus described my invention what I claim is,

1. In a toy boat; a casing secured in said boat extending downwardly and rearwardly and passing through an aperture through the bottom of said boat, a propeller shaft journa-led in said casing havingsecured to its rear end a propeller; a motor secured to the forward end of said casing and having the rear end of its shaft extending into said casing adjacent the forward end of the propeller shaft, and a flexible coupling member consisting of a non-metallic sleeve located in said casing and detachably secured to the ends of said shafts.

2. In a toy boat, the combination,'with a motor and a propeller to be driven by said motor; of a. shaft operatively connecting said 'motor and propeller, said shaft consisting of pins extendin through said sleeve and adj acent shaft en s to complete the shaft, said sleeve normally maintaining said shaft ends in slightly spaced relation to each other.

In testimonywhereof I hereunto aflixniy signature.
