The present invention relates to a propelling mechanism and has for its prime ob ect to provide rotating propellers which reciprocate back and forth along their axes.
Another very important object of the invention resides in the provision of a propelling mechanism of this nature comprising a pair of rotating propellers on a common axis, said propellers reciprocating back and forth oppositely to each other.
A still further ver imortant object of the invention resides in tfie provision of a propelling mechanism of this nature which is simple in its construction, strong and durable, compact and convenient in its arrangement of parts, thoroughly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which itis designed.
With the above and numerous other objects in View as will appear as the description proceeds, the invention resides in certain novel features of construction,and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawings:
Figure 1 is a side elevation of the mechanism embodying the features of my invention showing the same in a boat, the portion of the boat being shown in section,
Figure 2 is a top plan View of the mechanism,
Figure 3 is an enlarged detail side elevation thereof,
Figure 4 is a sectional view taken substan- L- l of Figure 3,
Figure 5 is a detail section taken substantially on the line 55 of Figure 3,
Figure6 is a perspective view of one end of the outer shaft,
Figure 7 is a longitudinal Vertical section taken substantially on the line 77 of Figure 2,
Figures 8 and 9 are sectional views taken substantially on the lines 88 and 99 of Figure 7.
Referring in I have shown a practical embodiment of the invention in which numerous changes in the details of construction may be resorted to without departing from the spirit of the 31 and is engaged by to the drawings in detail whereinvention, it will be seen that the numeral 5 denotes a base from which rises a standard 6 having a bearing 7 at the upper end thereof in which is journalled a hub 8 of a double crown gear 9. The bore of this hub ,is squarev to receive an outer hollow square shaft 10 in which is an inner square shaft 11. A thrust bearing 12, is disposed about the hub 8 at one end of the' bearing 7. A plurality of rollers 14: are held in place by means 15 so asto be disposed about the shaft 10, the axes of the bearing roller 14 being at right angles to the axis of the shafts 10 and 11. Thus the shaft 10 is free to reciprocate through the hub 8. The shaft 10 at one endhas a plurality of bearing rollers 16 held in place by suitable means 17 to bear against the faces of the shaft 11 to permit reciprocation of the shaft 11 in the shaft 10.
-Numeral 20. denotes a reciprocating element operated by any suitable motive power which has a connection 21 with one end of the inner shaft 11, and the connection 2i is formed with an extension 22 with which is engaged pivotally a pitman 24: which is engaged with a stud 25 on a gear 26 journalled on a stud 27 projecting from the bearing 7. This gear 25 is in mesh with one side of the double crown gear 9. A standard 28" is formed with a lateral extension 29 at its upper end having a stud 3O projecting therefrom on which is journalled a gear 31 meshing with the other side of the double crown gear 9. An eccentric stud 32 projects from the gear a pitman 34f pivotally engagedwith a connection 35 with the outer shaft 10. The connections 21 and 35 are similarly constructed and the detailed description of the connection 35 about to be given will suflice for the present purpose. Referring to Figures 4 and 5 particularly it will be seen that the shaft 10 has a circular portion formed with an annular groove 36.
A propeller 40 is mounted on one end of the outer shaft and a propeller ll is mounted on the adjacent end of the inner shaft.
In the present embodiment of the invention, a portion 42 of the outer shaft is cylindrical in construction and is slidable and journalled through a bearing sleeve 43 disposed through the rear end of the boat 44. This mounting, of course, is not of the essence of the invention.
Now from the above of the practical embodiment of the invention illustrated it will be readily apparent to those skilled in the art that as the member 20 reciprocates both a rotary and reciprocatory motion is imparted to each of the two shafts l0 and 11. The shafts 1 0 and 11 reciprocate in opposite direction but rotate in the same direction. p
It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.
fIt is apparent that changes in the details 0 arrangement of parts may be resorted to With-. out departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is:
In a propeller mechanism of the class described, an outer shaft, an inner shaft in the outer shaft, means causing the outer shaft and inner shaft to rotate together and permitting the shaft to reciprocate with respect to one another, propellers connected to adjacent ends of the shafts, and means for simul taneously rotating and reciprocating the shafts, said means comprising a crown gear on the outer shaft to rotate therewithand permitting the outer therethrough, a pair of gears in mesh with the double crown gear, said gears being arranged on opposite sides of the crown gear whereby the gears are rotated in oppositedirections, each gear .having a crank pinthereon, a pltman connecting the pin of one gear with one of the shafts, and a pitman connecting the pin of the other gear with the other shaft.
In testimony whereof I affix my signature.
