' for ships.

Another object is to provide improved means for applying energy derived from the pressure of currents within the air for the propulsion of a ship.

A further object is to provide a device of the character described having provisionof propelling the ship at diiferent speeds.

Another object is to provide improvedmeans for applying energy derived from the wind for propelling a ship in any direction regardless of the direction of the wind.

A still further object is to provide a device adapted to be actuated by wind pressure and provided with means for automatically compensating for variations in said wind pressure to deliver a uniform propelling force.

A still further object is to provide an improved device for applying wind pressure to the propelling of a ship afiording flexibility and ease of control.

I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout Figure 1 is a broken side elevation of a ship equipped with my improved propelling device disclosing the general arrangement and application thereof; Figure 2 is a broken plan view of Fig. 1; Figure 3 is a broken side elevation of the tower and windmill cap, parts being broken away and shown .in section to disclose the construction thereof; Figure 4 is a view taken at right angles to Fig. 3; Figure 5 is a broken plan view of the transmission gears; Figure 6 is a broken side elevation of the drive shaft and gearing showing the manner in which the direction and speed is controlled;

Figure 7 is a broken front elevation of the windmill; Figure 8 is a side elevation of Fig. 7; Figure 9 is a view of the back of one of the vanes; Figure 10 is a horizontal section of a vane showing the manner in which it is moved to compensate for variation in wind pressure; Figure 11 is a plan view of the steering mechanism; F igure 12 is a horizontal section of a connecting shaft showing the brake drum applied thereto; and Figure 13 is a side elevation of Fig. 12. i a

Referring to the drawings the numeral 1 is used to designate in general a ship upon the upper deck of which are mounted a plurality of towers 2 preferably built from angle iron sections to decrease air resistance thereagainst. Upon the top of each tower 2 is rotatably mounted a windmill cap 3 carried upon suitable roller bearings 4. Each cap 3 is provided with a horizontally disposed shaft 6 carried upon suitable bearings 7.

cured a windmill designated in general by the numeral 8 and consisting of a plurality of vanes 9 pivotally mounted upon a like plurality of radial rods 11 secured between a hub12 and an outer, rim 13 by means of suitable bearings 14. A spring 16 is provided upon each rod 11, one end of which is secured to the rod by means of a collar 10, the free end of said spring bearing against the back of the corresponding vane 9 to exert a pressure therea-gainst, the purpose. of which will hereinafter be more fully described.

A rudder 15 is secured upon each cap upon the side opposite the windmill to direct the windmill toward the wind in the usual manner.

The inner end of each shaft 6 carries a bevel gear 17 and is provided with a suitable thrust bearing 18. The gear 17 meshes with a similar bevel gear 19 secured upon the upper end of a vertically disposed connecting shaft 21 extending downwardly through the tower and the deck of the ship to be connected to a drive shaft 23 by means of a, bevel gear 24 meshing with a pair of oppositely faced bevel gears 26 and 27 rotatably mounted upon said drive shaft 23.

Clutch members 28 and 29 are secured upa on the adjacent faces of the gears 26 and 27 ship 1 as being provided with two windmills 8, each of which is connected with the drive shaft 23 in the manner above described. Separate levers 32 are providd for.

the manipulation of the clutch member by which the connecting shafts are operatively, connected to the drive shaft, in, this manner permitting either of the connecting shafts to be disconnected independently ofthe other to reduce the amount of power applied to said drive shaft 23, or to permit the operation of either windmill to be interrupted for necessary repair Work without interferring with the operation of the other. However, to insure against the possibility of causing one clutch member 29 to engage a member 26 in connection with one connecting shaft 21 and the other clutch member to engage the member 27 in connecting with the other connecting shaft 21, the levers 32 are interconnected as by a link 35 whereby the movement of one lever is limited with respect to the other.

Suitable brake drums 34 are provided upon each connecting shaft 21 whereby the rotatlonimay' be retarded or entirely prevented by means of a suitable brake band 36 and actuating connections 37 The drive shaft 23 is provided with gears 38 and 39 of different diametersupon the adjacent sides of which are secured clutch members 41 and 42 adapted to be engaged by a corresponding clutch member 43 feathered upon the drive shaft 23 and actuated by a yoke 44 whereby either of said clutch members 41 and 42 may be engaged and the corresponding gear 38 or 39 rotated.

Pairs of gears 46 and 47 secured upon parallel propeller shafts 48 mesh with the gears 38 and 39. The outer ends of the propeller shafts 48 extend outwardly through seen that the pressure of the stern ofthe ship and are provided withsuitable screw propellers 50 operating in the usual manner for propelling the ship through the water. I

From the above description it. is readily against the vanes of the windmills 8 will causea rotation thereof, which. rotation 1s imparted to the'connecting shafts 21 and thence to the drive shafts and the propeller shafts for operating the propeller screws. By means of the clutch member 30' and the oppositely faced bevel gears 26 and air I currents.

27 the direction of rotation of the drive shaft may be reversed when it is desird to. drive the propellers in a reverse direction, and. by means "of the gears 38 and39, and their meshing pairs of gears 46 and 47 the speed of rotation of the propellers may me changed at will. In the drawings I have provided for only two speeds but it is clear that additional speeds could be obtained by inserting additional sets of gears of proper ratio to give the desired speed.

The pivotally mounted and spring" controlled vaues 9 are arranged to automatically compensate for variations .in wind pressureand thus deliver a uniform driving force to the drive shaft 23. The springs 16 are made of a strength such that the normal wind pressure will not displace the vanes about their pivots; however, should the wind pressure become excessive, the excess pressure upon each vane will cause it to be slightly turnd against the pressure of the spring and thus present less surface to the Wind. This is accomplished by pivoting the vanes 9 along a line slightly at one side of the center line of the vane, and the springs 16 arranged to exert their pressure in opposition to the greater side of the vane. Thus only so much of thepressureof the wind against the greater side of the vane is the wind thereby maintaining the driving force substantially uniform and preventing undue stressupon-the driving connections.

Pins 20 secured to the rods 11 engage the sides of the bearings 14 to limit the movement of the vanes 9 about the pivot rods 11.

Power from the drive shaft 23 is also utilized in steerin the ship. ,This I accom plish byprovidmg a pair of bevel gears 51 upon the drive shaft 23. A gear 52 mounted upon a shaft 53 is engaged upon opposite sides by the gears 51, said gears 51 being controlled by a suitable clutch54 operated in a manner similar to the clutches 30 andv 43 whereby the shaft 53 may be rotated in either direction. Theshaft 53 is also provided with a pinion 55 meshing with a segment gear 56 secured upon the upperend of a rudder shaft 57 carrying a rudder 58 of any suitable construction'for steering the ship. Whenit is desired to alter the course of theship, the clutch 54 is moved to cause the shaft 53 to be notated in the desired direction, said shaft operating the pinion 55' and the segment gear 56 to turn the rudder to the desired angle. V

Y dditional mechanism may be driven from the drive shaft23 to meet the requirements o1 the ship. This is illustrated in Fig. 1 of the drawings wherein anair compressor 60-is shown connected to the shaft 23 by a belt 59.

From the above description it is seen that I have providedan improved device wherein I have made provision for the utilizing of wind pressure not 'onlyto propel the ship,.but for such other power purposes as may be required, the delivery of the power derived from the wind being delivered directly to a main drive shaft from which it may be utilized in any manner desired in the same manner as from the main drive of a power driven ship. Thus the same flexibilit' of delivery and control of power is ,avai able as with other sources of power,

and the fact that the ship is propelled by screws operating in the water in the usual manner permits'the' ship to follow any desired course regardless of the direction of the Wind, as even when the ship is headed directly into'the wind, the power developed by the windmills will be delivered to the propellers operating within the water to cause a forward movement of the ship.-
