.journal-studs 9 are mounted.

tending upwardly from said upper housing section 2 is a hollow shaft or sleeve G, preferably forming an integral part of said uppcr housing-section 2. The annular malrginal meeting surfaceswof the connected housing sections are provided with af plurality of radiating openings which provide ral diating bearing-portions 7, corresponding to the position and number of paddles or blades employed.

Each paddle consists of a blade 8 of anyv extends around the outer ends of the blades 8, and not only serves to pivot the said outer ends but also to strengthen the blades' and maintain the same properly spaced one from another. Said supporting ring 12 rotates with the paddle-wheel or propeller, and is made of a tapering thickness out to its outer peripheryv so as to offer as little resistance to the water as possible. 1

Secured to the inner end of each blade 8 f is a stud-shaft or journal-member 15, the same being provided at its one end with a bifurcated fastening plate 1G which straddles the thickness of the blade. and rivets 17 passing therethrough firmly atlixes said studshaft or journal-member to the blade.

Said stud-shafts or journal-members 15 are rotatably mounted in the bearing-portions 7 formed in said housing sections 2 and 3, so that their free ends extend into said interior chamber 5 provided by the latter. integrally formed at the free end 0f eachy stud-shaft or journalanember 15 is a crank-arm 18 having a crank-pin'lS projecting therefrom. Mounted upon each crank-pin 18', if desired, is an antifriction roller 19. Y

The paddle-wheel or propeller is designed to be mounted beneath the boat-bottom 20, at the stern thereof, and is arranged'in a horizontal position. There are, of course, many wavs of mounting said paddle-wheel or propeller relative to the boat to be propelled thereby, consequently the means for ymounting the saine, such as shown inthe drawings. mustbe deemed merely illustrative and not in a limiting sense. Such means comprises a suitable bearing member 21 affixed to the'boat-bottom 20, and provided with anyI suitable forni of'lstiitiing-box 22.

Said ring 12,V

adapted to render the same water-tight. Rotatably mounted in said bearing-member 21, and extending upwardly therethrough into the interior of the boat is the hollow shaft or sleeveti, to the upper end of which is secured a beve'lLgear 23, with which meshes a Ybevel pinion Q41- through which the power Y'of the transmission shaft 25 is applied to rotate said hollow-shaft or sleeve 6, and

consequently the housing-sections 2 and o and the blades 8 connected therewith.

Mounted within the interior chamber V5 of said housing sections 9. and 3 is a carnmember 26 which is provided in its sides with a cam-groove 27, which for convenience in explaining the operations eht'ected thereby, l will describe as possessing an upper groove portion and a lower groove por- 6, and which` is preferably journal-ed in stationary sleeve 29.. The lower or under side of said cam-meinber is provided with a pivot journal 30 which supported upon a removable foot-step bearing 31 secured in said-lower housing-section 3. Said verticalshaft 28 may be rotated to turn said cammember 26 to shift vits position for the purpose of shiftingftlie point of the feat iering f the blades 8. as will be subsequently described. ln order to secure the cam-member 26 in any position to which it has been shifted or adjusted by rotating the vertical shaft- 28, l provide a stationary notched quadrant 32,-and l secure upon said verticalH shaft 2S an articulate-d lever-arm 38 which y withk are revolved by the driving mechanism,

the cam-member. 26 remains stationary. but may be `independently moved for adjust# ment purposes.'V

The cam-groove 27 is formed so as to give the crank-pins 18 a vertically reciprocating movement as they travel around the camgroove, and this reciprocating movement os- I ucillates the crank-arms 18 sutli'ciently to give enter said cani-groove 227 the blades 8 a rotation on their axes to the extent of a quarter turn, thus moving the blades 8, alternately to vertical and horizontal pcsitions. The cam-groove is so shaped, by preference, that two or more blades 8, at least. may at all times operate to propel the boat.

An inspection of Fig. 3 of the drawings will explain the action of the cam- groove 2,7 upon the crank-pins 18", crank-arms 18 and blades 8. When the crank-pins are moving in the lower groove-portion of the cani-groove the blades 8 are presented faceward to the water and in propelling position. As the crank-pins enter the rise from the lower groove-portion to the upper groove-portion, the crank-arms are caused to move upward, thus turning the studshafts or journal members 15, and when the upper groove-portion is reached the studshafts or journal-members have completed a quarter turn and consequently the blades 8 are presented edgewise to the water, or in feathering position relative thereto. As the rotation of the paddle-wheel and its blades continue, the crank-pins 18 continue their travel until they reach the descent joining the upper groove-portion to the lower, and

are thereby caused to move downward again, thus turning the stud-shafts or journal inembers a quarter turn in the opposite direction, thereby the blades 8 are again turned to propelling position, this reciprocating oscillation of the blades continuing as the crank-pins are carried around in contact with the stationary cam-groove 27 by the revolution of the paddle-wheel or propeller.

While the cam-member 26 remains in any given position, the blades will be made to work-that is will he changed from vertical to horizontal positions-at a certain part of their revolution corresponding to the cam rise and descent in the cam-groove 2T. If the vertical shaft be turned so as to turn the cani-member Q6, thus changing the positions of the cam rise and descent of the cam* groove, the working point of the blades will be correspondingly changed. It will thus be apparent that by shifting or adjusting the cam-member 26, the pilot may operate the paddle-wheel or propeller in such a way as to shift its propelling force so as to steer or change the course of the boat as desired.

I am aware that some changes may be made in the arrangements and combinaof the present invention as set forth in theforegoing specification and as illustrated in the accompanying drawings. Hence, I do not limit my invention to the exact arrangements and combinations of the parts as above described and as illustrated in the accompanying drawings, nor do I coniine myself to the exact details of the construction of the said parts.

I claim:-

In a device of the kind described, a rotary housing` providing an interior chamber, a hollow shaft extending upwardly from said housing` for rotating the same, a stationary tubular sleeve upon which said hollow shaft rotates, said housing being provided at its outer marginal portions with radiating bearing-portions extending to said interior chamber, a plurality of paddle blades, journalmembers affixed to the inner ends of said.

bladesA and jeurnaled in said bearing-portions of said housing, a cam-member having a cani-groove positioned in said interior chamber and normally stationary relative toV said housing, crank-arms connected with the inner ends of said journal-iiiembers, crank-pins projecting from said crankarms into said cam-groove and traveling therein when said housing and said blades are revolved, an outer ring having bearing openings therein, journal studs conn nected with the outer ends of said blades and journaled in said bearing openings of said ring, means for independently adjusting said cam-member to shift the feathering point of said blades, comprising a vertical shaft affixed to said cam-member and extending upwardly through said stationary tubular sleeve,V means for rotating said shaft as desired, and means cooperating with said vertical shaft for holding the saine against rotation and thus locking said cam-member in desired adjusted position, all for the purposes described.

In testimony, that I claim the invention set forth above I have hereunto set my hand this twelfth day of August, 1915.

DAVID LINDSAY.
