CHARLES EDGAR FOX, OF MINNEAPOLIS, MINNESOTA.

BOAT-PROPELLER.

SPECIFICATION forming part of Letters Patent No. 452,467, dated May 19, 1891.

Application tiled October 13, 1890. Serial No. 367,989. (No model.)

To all whom it may concern:

Be it known that I, CHARLES EDGAR Fox, a citizen of the United States, residing at Minneapolis, in the State of Minnesota, have invented certain new and useful Improvements in Boat-Propellers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in mechanism forpropellingboats; andit consists in the construction, novel combination, and adaptation of parts hereinafter described and claimed.

In the accompanying drawings, Figure lis a broken longitudinal elevation of a boat, the middle portion thereof being broken away to illustrate myimprovements. Fig. 2 is a vertical transverse sectional view of the same, illustrating my improvements at right angles to Fig. l.

Referring by letter to the said drawings, A indicates a boat, which may be of any ordinary orapproved construction. At a suitable point Within the boat adjacent t the stern thereof I secure by bolts or otherwise to the bottom thereof a transversely-arranged yoke or arch frame-piece B, which forms the main support of my improved mechanism. Formed integral with or secured to the vertical branches of the, frame-piece B, adjacent to the bottom thereof, is a transverse bar C, which is provided at its middle with an enlarged portion, which is recessed in its upper side, as at a, to afford a seat or bearing for the lower end of a vertical shaft D, which is also journaled adjacent to its upper end in the horizontal branch of the frame B. At a suitable elevation upon the shaft D, between its bearings, I iix a horizontal beveled gear- Adjacent to its inner end the propellershaft F takes through a bearing Iat the end of a depending bracket-arm J, which may be formed integral with or suitably secured to the horizontal branch of the frame B.

The vertical shaft D, before described, has fixed to its upper end a horizontal beveled gear-wheel K, which meshes with a vertical gear L, presently to be described.

Suitably secured to and rising from the horizontal branch of the frame B are vertical standards or uprights M, which are connected together by a transverse downwardly-bowed bar N, which,if desired, may be castor formed integral with said upriglits.

.Iournaled in the respective nprights M, ata suitable elevation, is a transverse shaft O, which carries adjacent to its middle a fixed sprocket-wheel I), and adjacent to one of its bearings the vertical beveled gear L, which meshes with and transmits motion to the horizontal gear K. Journaled in lthe said nprights M at their upper ends is another transverse shaft Q, which also carries at its middle a Vsprocket-wheel R, which is connected with and transmits motion to the sprocket-wheel l) by means of a chain belt S, which travels around said wheels.

Suitably keyed or otherwise fixed upon the ends of the upper transverse shaft Q at right angles to each other are crank-arms T, which the operator turns when he desires to propel the boat.

In operation when the crank-arms have been turned by an operator the sprocket-wheel R, through the medium of the chain belt S, will transmit motion to the sprocket-wheel P, which will cause the gearL to transmit motion to the upper horizontal gear, which turning the vertical shaftsets the lower horizontal gear in motion and in turn the pinion on the propeller-shaft and the propeller. It will also be seen that by the construction described the boat may be quickly stopped and reversed, if desired.

l IlIaving described my invention, what I claim is* In a power mechanism forpropelling boats, the transversely-arranged frame B, having the lower transverse bar adapted to afford a seat for the lower end of the vertical shaft, the said vertical shaft journaled in the hori- IOO zontal branch of said frame l and earl-ying the horizontal gears E and K, the standards secured to and rising from the horizontal branch of the frame B, the bowed transverse bar Connecting said standards, the lower transverse shaft journaled in said standards, carrying the vertieal gear, meshing with the upper gear of the vertical shaft, the sprocketwheel Xed on said lower transverse shaft, the upper transverse shaft also journaled in the upright standards and carrying crankarms at its ends, the sprocket-wheel iixed on said upper shaft, a chain belt connecting the sprocket-wheels on the upper and lower shafts, and the rearwardly and downwardly extendinp` hanger J, connected at its upper end to the transverse branch of the frameB and having a horizontally-oblique journalbearing at its lower end, in combination with a propeller and its shaft, journaled in the bearingof the hangerJ and oarryingapinion meshing with the lower horizontal gear, all adapted to operate substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES EDGAR FOX.
