PROPELLING MECHANISM FOR BOATS, VESSELS,. AND THE LIKE.

Application filed September 30, 1926. Serial No. 138,613.

This invention relates to an improvement in propelling mechanisms for boats, vessels, and the like, and particularly to that class of boats, etc., propelled wholly or in part by the wind.

The object of this invention is to provide a simple, reliable and eliicient mechanism of the class described.

In the accompanying drawings:

Fig. 1 is a view partly in side elevation and partly in vertical central section of a boat provided with my improved propelling mechanism;

Fig. 2 is a top or plan View thereof;

Fig. 8 is a transverse sectional view on the line 33 of Fig. 2;

Fig. 4 is a detached perspective View of one of the impellers with its blades arranged in their operative positions; and

Fig. 5 is a view thereof with the bladesin their collapsed or inoperative positions.

In carrying out my invention in the embodiment herein shown for illustration, 1 provide a boat 10 with a centrally-located rectangular opening 11 arranged lengthwise of the boat and extending vertically through the depth thereof, so as to be open at its bottom to the water and at its top to the air. The walls of the aforesaid opening 11 are extended above the deck 12 of the boat. so as to constitute a rectangular shield 18 for the purpose as will hereinafter appear. Partly within the opening 11 and partly above the same I mount, as shown, two vertical rotary impellers, each consisting of a group of four rectangular blades 14, 149, lt and 14 radiating from a transversely-arranged horizontal shaft 15, the opposite ends of which have bearing in pillow-blocks 16 mounted on the opposite sides of the opening 11 and upon the upper edge of the shield 13. The blades 14 and 14 of each impeller are preferably made of one piece of sheet-metal, and at the point of juncture are formed with integral fingers 1'? adapted to embrace the shaft 15 aforesaid. The blades 14 and 14 are independently formed and are respectively provided with fingers 18 and 19 and also adapted to embrace the shaft 15 in such manner that the said blades may be swung with respect to the said shaft and against the blades 1 1 and 14 respectively, as shown in Fig. 5, so that the impellers may be thus rendered inoperative when desired.

For the purpose of maintaining the individual blades of each impeller in correct radial operative position with respect to their complementary blades, I employ four tie-rods 21, each of which is provided at its opposite ends respectively with an inwardly-turned hook 22 designed to enter a positioning-notch 23, one of which is formed in the outer ends of each blade. For the purpose of drawing the tie-rods 21 taut, one of the said rods of each impeller is pro vided with a turn-buckle take-up 2-1.

As thus constructed and arranged, the upper half of each impeller is exposed to the action of the wind, while its lower portion, which is partly immersed in the water, is shielded therefrom by the shield 13, consequently, wind blowing from any point to the rear of the boat will cause the impellers to rotate. This rotation of the impellers,

as just described, will positively propel the boat forward, since the lower portions of the impellers are immersed in the water.

It is obvious that the number of impellers upon the boat, as well as the number of blades in each impeller, may be variedwithout departing from the spirit and scope of my invention.

I claim:

1. The combination with a boat having an opening extending vertically therethrough, of a rotary impeller located partly in the said opening in such position that its lower portion is immersed in water and its upper portion exposed to the action of the wind, the said impeller consisting of a plurality of radial blades, and a shield for preventing the wind from acting upon the lower portion of the impeller.

2. The combination with a boat having an opening extending vertically therethrough, of a rotary impeller located partly in the said opening in such position that its lower portion is immersed in water and its upper portion exposed to the action of the wind, the said impeller consisting of a plurality of pivotal radial blades. detachable braces for maintaining the said blades in operative position with respect to each other, and a shield for preventing the wind from acting upon the lower portion of the impeller.

In testimony whereof, I have signed this specification.

FRED BURGE.
