To all whom it may concern:

Be it known that I, HUGH' P..Mineo1vn, a citizen of the United States, residing at Anaconda, in the county of Deerl'o'dge and State of Montana, have invented certain new and useful Improvements in Water-Motors or Propellers, of which the following is a specification, reference being had to the accompanying drawings;

- This invention relates todevices for either securing power from a stream of water or for propelling bodies by engagement with a relatively fixed body of water, and particularly to a motor or propeller of this character' in which endless chains are used passing around suitable power receiving or deliver ing' wheels, these chains carryingblades.

A further object of the invention is to provide, in a motor of this character, means for supporting the chain's so that they will travel on a fixed and endless path, and further to provide means whereby the blades and chains may properly turn or pass from the upper flight of the chains to tho lower flight thereof.

Other objects have to do with the details of" construction of an apparatus of this character as will hereafter more fully appear.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my improved waterm'otor;

Fig. 2 is an end view, the fiume being in section, I

Fig. 3 is a perspective detail view of one of the carriages and blades and aportion of the track;

Fig. 1 is an underside plan view of the construction shown in Fig. 3";

Fig. 5 is a perspective detail view of one of the blades showing the manner in which it is connected to the sprocket chains 17 Fig. 6- is a side elevation of' the hull of a boat showing my invention appliedthereto as a motor; and

Fig: 7 is an end view of the construction shown in Fig. 6.

' In Figs; 1 to 5, I show my invention as applied to receiving power from a running stream, and I will refer first tothisapplication of my invention. In these Figs. 1 to 5, 1'0 designates a flume having the side boards 11 whereby to direct the flow of water through a relatively narrow channel.

Extending upward from the side boards 11 are the standards or supports 12, four of which are illustrated as being used. Mounted upon one pair of these supports 12' at one end of the fl-ume is a shaft 13carrying the relatively smooth, spaced Wheels 14, and rotatably mounted the othersupporting members 12 is the shaft 15' carrying the spaced sprocket wheels 16.- Passingl over these sprocket wheels and over the smooth faced wheels are the endless sprocket chains .17. These wheels 13 and 16 are of such: diameter that the lower flight of the sprocket chains is just above the level of the upper edges: of the flume boards 11.

Attached to the supports 12 in any suit able manner are the oppositely disposed pairs of track rods 18 and 19. Each of these track rods is approximately elliptical in form having upper and lower flights joined by curved ends. 'These track rods are sup ported slightly outward from the inner faces of the supports or standards 12'.

Operating between these tracks 17 and 18 are a' plurality of carriages each carrying a blade. Each carriage comprises the transversel y extending axles as they may be termed, 20 and 21,. each axle having at its ends the grooved wheels 22' which are adapted to engage between the track rods 18 and 19' and engage with one of these track rods; The axles 20 and 2'1 are connected by longitudinally extending links 23 pivotall-y connected to the axles" soas to have free oscillation. Mounted upon the axle 21 and extending out therefrom is a blade 24 which is held in a position perpendicular to the path of movement of the blade carriage by means of braces 25 which extend downward to the axle 2-0 and are attached to this axle in any suitable manner. The upper ends of these braces are attached to the outer ends of the blades upon the rear face thereof. The chain 17, as illustrated most clearly in Fig; 3, is attached, as at 26, to the axle 21,

but the chain is not attached to the axle 20.

24 in the passage of water through the fl'ume,

the blades will be causedto travel in the direction of the arrow, Fig. 1, and in a fixed LJI elliptical path. As the carriage for each blade moves along the upper flight, the

wheels 22 will engage with the track rod 19. As the carriage moves along the lower flight, however, the rear wheels 22, those on the axle 21, will engage with the track rod 18, but the forward wheels, those on the axle 20, will engage with the track rod 19, due to the pressure on the paddle. When the blades reach the turning point of the tracks the wheels will follow the curvature of the tracks but the links 23 will extend diagonally across the arc of movement of the wheels as illustrated in Fig. 1. Thus there is no binding action of the carriages on the track but the several carriages move perfectly freely thereon with but a' minimum of frictional resistance and a maximum of efliciency. The blades strike the water or dip into the water very quickly, that is, take their vertical position within the water very quickly so as to receive the impact .of the current almost immediately that they enter the chute or fiume, so that there is very little loss of power at the time the blade enters the flume. In the same manner the blade leaves the water very quickly so that there is but little reaction at the time the blade leaves it.

While I have heretofore described my device as intended to be driven by water, it is also obvious that it may be used as a propeller as illustrated in Figs. 6 and 7. In this construction beams or supports 27 are shown as extending across the vessel and supporting the supports 12 which are the equivalent of the supports 12. Under these circumstances the shaft 15 will be driven by power instead of receiving power from the blades and the blades will engage with the water and urge the vessel or other object forward. It will be seen from Fig. 6 that the upper flight of blades is always above the water line, while the lower flight dips into the water. Inasmuch as the construction of the remainder of the apparatus is the same as in the former case with simply a reversal of the action of the mechanism, it is not believed that detail views or descriptions are necessary.

The usefulness of the device for propelling vessels will be apparent. The propellers so constructed will: be very efiective and are particularly adapted for driving boats in shallow water. Throughout the claims I shall refer to my construction as a water motor. It is to be understood that this term includes a device which is either operated by the force of running water or which operates upon water in the manner of a propeller. d H I Having described the invention, what .I claim is: i
