Abstract
Abstract A rotatable wheel through which a plurality of similar, axially spaced, tubular fluid-containing spokes diametrically extend, each spoke terminating at each of its extremities in a fluid chamber, the fluid chambers of each spoke being directed in circumferential directions exteriorally of said wheel. An individual electrical heating element positioned in each fluid chamber, the elements being electrically and individually connected to contacts arranged in a concentric series on said wheel so as to be individually, successively and electrically contacted to energize the elements on the rising side of said wheel to force the liquid through each spoke to the descending side of said wheel to gravitationally impart rotation to the latter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
A vapor driven motor comprising: a. a rotatable drum mounted on a horizontal axis; b. a plurality of equally spaced fluid-containing, similar spokes diametrically mounted in said drum; c. a fluid chamber mounted on and communicating with each extremity of each spoke; d. a plurality of individual electrically powered heating elements each of which is associated with one of said fluid chambers; and e. means for successively and individually energizing the elements on the ascending side of said drum so as to thermally drive fluid through each spoke to the fluid chambers on the descending side of said drum to create rotative unbalance.
Claim 2
Dependent Claim
103 words
A vapor driven motor comprising: a. a rotatable drum mounted on a horizontal axis; b. a plurality of equally spaced fluid-containing, similar spokes diametrically mounted in said drum; c. a fluid chamber mounted on and communicating with each extremity of each spoke; d. a plurality of individual electrically powered heating elements each of which is associated with one of said fluid chambers; and e. means for successively and individually energizing the elements on the ascending side of said drum so as to thermally drive fluid through each spoke to the fluid chambers on the descending side of said drum to create rotative unbalance.
Claim 3
Dependent Claim
33 words
A vapor driven motor as described in claim 1 in which the spokes comprise: a. straight hollow tubes passing through the axis of said rum in drum spaced apart side by side relation.
Claim 4
Dependent Claim
52 words
A vapor driven motor as described in claim 1 in which the fluid chambers comprise: a. elongated chambers connected at their one extremity to the opposite extremities of their respective spokes so as to lead and preceed the latter in the common plane of rotation of the outer extremity of each spoke.
Claim 5
Dependent Claim
42 words
A vapor driven motor as described in claim 3 in which the heating element comprises: a. a tubular electrical resistance element, b. an insulated heater mounted in the leading extremity of each chamber and supporting the resistance element internally of the chamber.
Claim 6
Dependent Claim
96 words
A vapor driven motor as described in claim 1 in which the means for successively and individually energizing the elements comprises: a. an annular series of brush contacts axially positioned on one extremity of said drum; b. a commutator disc axially and stationarily positioned adjacent said latter one extremity; c. an electrical contact leaf mounted on said disc so as to be frictionally and successively contacted by said brush contacts as said drum rotates; and d. an electrical conductor connecting each element with one of said brush contacts to successively close electrical circuits to said elements.
Claim 7
Dependent Claim
27 words
A vapor driven motor as described in claim 3 in which: a. said elongated chambers are curvated to substantially conform to the circumferential curvature of said drum.
Claim 8
Dependent Claim
51 words
A vapor driven motor as described in claim 3 in which: a. the said connections between the spokes and the adjacent fluid chambers are positioned in close proximity to the radially distant wall of each chamber to facilitate gravitational expulsion of fluid as the chambers approach the bottom of said drum.
