This invention relates to improvements in power mechanism and has particular refer- :ence to propulsion means for ships.
A'further object is to produce a device 5, wherein standard mechanicalpractises are employed. 1 7
;A further object is "to produce a device which is economical to install.
Other objects and advantages will be ap- 119. parent-during the course ofthe following descrlptlon.

" Figure 4 is a diagrammatic view illustrating. the principle involved: i I In ship propulsion the propeller of the ship is acting against a fluid, which fluid being unconfined, tends to dissipate in all directions, and therefore, a large percentage of power delivered bythe engines to the propeller is lost. -V
Applicant has therefore devised a means for retaining this power and again returning the same to'the propeller shaft.
' In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention,the numeral 5 designates a ship having the customary propeller shaft 6-upon which the pro- 'peller 7 is keyed. The end of this shaft 6 is teeth 9 formed adjacent the end thereof. A "casing 11 partly surrounds the path of rotation of thepropeller blades and also surrounds the blades-12 of an impeller 13. This impeller wheel is free to rotate upon the re- ,duced portion 8 of the shaft 6.. The casing 11 carries spokes 14 which support a ring 16 in which a bearing 17is mounted. This bearing 17 serves to support shafts 18 and 19. 7 These reduced in cross-section as shown at 8 and has 193QJiSeria1 at: 458,650.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of par-ts may be resorted to without departing fZ aQ-jf v a 1,826,53
