jects is to provide a novel structure of a simple, practical nature that will have a powerful action, and at the same t1me1s compact so that it will occupy but little space.

A further object is to so construct the mechanism that it is housed and protected, thus adapting it for the use of vessels in either deep or shallow water.

A further and important object is"to provide mechanism that can be successively employed in connection with a compound engine, being separately connected thereto so'that the power of each is directly utilized.

Another object is to provide means which will efiectively maintain the pistons in a predetermined cycle of 'movement in order to insure at all times the proper sinuous operation of the propeller.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal sectional view through a portion of a vessel, showing the propeller mechanism in elevation. Fig. 2 is a cross sectional view through the same. Fig. 3 is a horizontal sectional view. Fig.4 is a diagrammatic view illustrating the different positions assumed by a propeller blade during its cycle of movement. Fig. 5 is a longitudinal sectional view showing a slightly modified form of construction. Fig. 6 is a horizontal sectional viewthrough the same.

Similar reference numerals designate corresponding parts 1n all the figures of the:

drawings.

In the embodiment illustrated, the hull of the boat is designated 7, and may be of any suitable type, the bottom 8 thereof having a central longitudinally disposed channel 9.

It is open ended, and is bottomless. In this channel operates the propeller, which is rnornnnme MECHANISM.

capable of a sinuous movement, and com prises sections or'blades 10 that are inextensible, {and arehingedly connected as These blades are preferably constructed of sheet metal, reinforced by two or more bars 12 of angle iron orjsuitable material disposed longitudinally of said blades. f I

Upon the portion of the'bo-ttom in which is formed the channel and directly above the propeller is' an engine, preferablyof the compound type, that is to say, comprising a series of cylinders 13 of successively greater diameter, each cylinder having a suitable" steam or .motive fluid chest I l, and the exhaust from one cylinder being conducted to the intake of the next by a suitable pipe 15. Asupply pipe 16 is connected to the steam chest of the, high pressure cylinder, and an exhaust pipe 1'7 leads from the steam chest of the low pressure cylinder.

Operating in each cylinder is a piston 18,

which is connected ,toa piston rod 19 eX- te'nding through both ends of the cylinder, said plston rod havln'g connected to its upper and'lower ends,

cross heads

20 and 21 thatrespectively operatebetween guides 22 and 23- Pitmen Q l-are pivoted at their upper ends to the cross heads QO'andconSequently to'the lower ends of the piston rods, and are pivoted at their lower ends to the sections or blades of the propeller, as shown at 25. Said pitmen operate through slots 26 in the bottom of the boat, which slots communicate with'the c hannel, andthe cross heads 9.0 preferably operate in water tight compartnients 27 formed by walls28 secured to the guides 22.

Inasmuch as the structure thus far described would permit unlimited swinging of the propeller longitudinally in the channel,

means are provided for governing 7 such movement, and in the present embodiment this means consists of swinging links 28 pivoted as shown at Q9;to the walls of the channel, and as illustrated at 30 to the'propeller. Instead of one setof links as shown in Figs. 1 and a double set may be-employed, as illustratedin Fig. 5,"the links 31 oneither side being connected by a common pivot 32 to the side walls of the channel, and being pivoted at their' outer ends, as shown at 33 to the ends of the propeller. \Vith this exception the structure illustrated in Figs. 5

and 6 is the same as that disclosed in Figs;

1-4; inclusive, and therefore the same reference numerals have been employed.

In order to absolutely insure the proper sequence of movement of the different pistons, a shaft 34 is employed located above the cylinders, and journaled in boxes 35 carried by standards 36 that are fixed to the guides 23. This shaft is provided with angularly disposed cranks 37 and pitmen 38, connected to said cranks, are pivoted to the upper cross heads 21, and consequently to the piston rods 19. The shaft 34; is furthermore provided with eccentrics 39 surrounded by straps 40 and connected to these straps are pitmen 41, which are connected to valve stems 42 and serve to operate the valves of the engine, as will be obvious.

The operation of the mechanism may be briefly outlined as follows: Taking one blade or section of the propeller, referring to Figs. 1 and 4, and assuming that said blade is in its lowermost position, as shown in Fig. 4 at A, starting at a horizontal position, the same is moved upwardly, as shown at B and C, in which case, it is disposed at substantially the inclination shown. The direction of movement of said blade is indicated by the arrows in full lines, and its action against the water is indicated by the arrows in dotted lines. As it reaches the limit of its bodily upward movement, it assumes a horizontal position, as shown at B, and then it moves downwardly and shifts to a downward inclination as illustrated at E and F, whereupon its under side is acting against the water, as indicated. Upon.

reaching its downward limit of movement it again reverses its angle of inclination for the upward movement, the horizontal position being shown at G. Each of the blades or sections of the propeller follows the one before it in the same cycle of movement, and consequently the propeller, as a whole, has a sinuous movement, producing great force, ,As already stated, its longitudinal movement of the channel is governed by the links 28 01-31, and the proper operation of the engine is secured by the crank shaft 34 and its connection with the pistons. Moreover, inasmuch as the propeller is housed within the bottom of the boat, it is completely protected from exterior obstructions and the mechanism is applicable to vessels of any draft and for use in both deep and shallow water.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. For

instance, while the structure is shown as means for propelling a vessel, it may be mounted on a stationary support and constitute means forpropelling liquid or it can also be utilized as a motor, the propeller being placed in running water and the current effecting its operation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
