V convertibility however froma propeller'toV a'current motor and from a current'motor pelle-r the member 15 which is here shown as the driven member, may be used as the driving m'enifbe'r, it being immaterial to the inventlon at which end thev power is applied.
Of course with the traverse of the blocks 16 back and forth along the race-ways fm ofthe member 15 during the rotation of the latter, ,rotationwill necessarily be imparted to Vthe blade-shafts 17 and hence to the blades 18. In their rotation about their own individual i axes, and" in their revolution about the common axisof the members 6' and 8, the blades operate through the water 4 in the same manner described therefor in my patent` aforesaid, and a repetition of this feature is not. necessary in .the present description. Y
In the present embodiment of-my inven- Y other relatively movable parts. The rod V9 Y insures stiffness for thestructure making it possiblejto utilize the propeller as `a current motor by a proper degree of submergenceV ofthe apparatus in a running stream.V This to a propellerfis likewise 4inherent' in the structure of myV patent aforesaid, the two structures having this feature; in common. I vmay ofcourse departfin a measure from the details here shown without in any' wise aiectingthe nature or spirit of my inven- -tion-fl Features shown but not alluded to are either well knowninthe art, or are already fully described.' in my patent aforesaid. In the present illustration and assuming the apparatus operates as a propeller, theV disks 6 Vand 8 may be considered as the driving members. V`Having described my,invention what I claim is :-V l Y '1. In combination with a rotatable mem ber provided vwith a series of race-ways dis-k posed diametrically and intersecting at the axis offsaid member,v a pair of rotatable driving members spacedvapart and mounted toy rotate about acommon axis eccentric to thfeJ1 waxis of the y race-way member, bladeshafts sup'ported yloosely by,l and lbetween the drivingmembers, blocks secured to one Vof.
the terminals of the bladeshafts andfree ive cents each, by addressing the Washington, ID. C.
to' traverse the 'race-ways, and blades on the shafts betweenY the driving, members, sub- VVstantiallyas set 1forth. i Y
' 2. In vcombination with a rotatable mem-V ber provided with a series of radial raceways, a pair of rotatable driving members spaced apart and mounted'to rotate about a common :axis eccentric to the axis'xof the ,race-wayvmember, a hollow shaft connecting the members aforesaid, 'a' stationaryrod serving as a bearing for and traversing the hollow shaft, one end of the rod projecting outside .the hollow shaft'- and bey-0nd one( of the rotatable driving members, means for rigidly supportingsaid projecting lend of` the rod, parallel shafts mounted loosely [in and between the driving members, one end of each shaft projecting beyond the driving member *whichV is adjacent the 'race-way member, blocks rigidly secured to said shafts and free to traverse the race-Ways, and blades mounted centrally and rigidly tothe shafts between the driving members and clearing saidmembers. Y
3. In a current motor or propeller, a pair mon axis and spaced apart, shafts disposed parallel to said axis and operating loosely in land between the members, blades secured to rotate with the shafts, a member disposedA adjacent to the first members and rotatable about an independent axis eccentric to the axis of the first mentioned, members, and slides disposed about the axis of the shafts Vcooperating with the last mentioned member.
for causing a simultaneous rotation of theblades about their individual axesand a revolution of the blades and their Ashafts about the common axis of the first mentioned rotatable members. Y i
4. In combination with a'rotat-able member provided with a series of race-ways disposed diametrically and intersecting at-the axis of vsaid member, a pair of rotatable driving members spaced apart and mounted to vrotate about 'a' common axis eccentric to the axis of the race-way member, blade# shafts supported loosely by, and between the driving members, slides secured at'ithe terminals of the blade-shafts andr'free to traverse the raceways, and'blades' on the shafts between the driving Vmembers.'
