JOHN \VESLEY MACK DONEL MOORE, OF MOSS, TENNESSEE.

PROPELLER FOR BOATS.

SPECIFICATIONforming part of Letters Patent No. 583,762, dated June 1, 1897.

Application filed December 19, 1896. Serial No. 616,265. (No model.)

To all whom it may concern:

Be it known that 1, JOHN WESLEY MACK DoNELMoonE, a citizen of the United States, residing at Moss, in the county of Clay and State of Tennessee, have invented certain new and useful Improvements in Propellers for Boats; 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 relates to improvements in mechanism for propelling boats and similar vessels; and the object is to provide a simple, durable, and efficient de vice for this purpose.

To this end the invention consists in the construction, combination, and arrangement of the same, as Will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings the same figures of reference indicate the same parts of the invention.

Figure 1 is a perspective view of my improved propelling mechanism for boats. Fig. 2 is an enlarged side elevation of the ratchetdrum, and Fig. 3 is a vertical longitudinal section of the same.

1 represents the main driving-shaft,'suitably mounted in the usual bearings in the boat. This shaft is provided with a sprocketwheel 2, from which a sprocket-chain 3 runs to a smaller sprocketwheel 4 on a countershaft 5.

6 represents a balance or fly wheel also fixed on the counter-shaft 5, and 7 is a sprocketwheel also rigidly fixed on the said shaft 5. A sprocket-chain 8 connects said wheel 7 with a sprocket-wheel 9 on a transverse shaft 10, mounted in hearings in the sides of the boat or vessel, the outer ends of which project a sufficient distance outside of' the hull to receive the sprocket-pulleys 12 and 13.

14 and 15 are similar sprocket-pulleys loosely mounted on short shafts 16 17, secured on the outside of the hull and in the same horizontal plane as the shaft 10.

1S and 19 represent endless sprocket-chain belts connecting the sprocket-pulleys 12 and 14 011 the one side and the sprocket-pulleys strap, one end of which is suitably securedto said drum, and its other end, after passing around the drum, is secured to a foot-lever 26,

fulcrumed in a bracket 27, fixed to the frame work in the bottom of the boat. A second smaller strap 28 has one end 29 fastened to the drum, and it then passes around said drum in the opposite direction to the strap 25,

its lower end 30 being secured to the upper end of a spiral spring 31, the lower end of which is fixed to an eyebolt 32, secured to the framework in the bottom of the boat.

33 33 represent integral brackets on the inside of the drum 2-4, and these are each formed with transverse circular recesses 34, in each of which is pivoted the correspondingly-shaped hub 35 of a pawl 36, the free end of which is adapted to engage the star-shaped teeth 23 of the ratchet-wheels, being held in contact therewith by the fiat springs 37.

It will be seen by reference to the drawings that two complete foot-lever systems are employed, one on each side of the main drivingwheel 2, and when alternately operated by the right and left foot a continuous rotary motion is imparted to the endless sprocket-

chain belts

18 and 19 in the direction shown by the represents a lever fulcrumed on a rod 41 in the frame and provided with a friction brake-shoe 42, which bears against the flywheel, and 38 is a handle-bar connected to the brake-lever 40 by a rod 43, its hand-grip 39 being within convenient reach of the opersecure by Letters Patent of the United States,

1. A propeller for boats, comprising the main driving-shaft, the sprocket-Wheel mounted thereon, the counter-shaft; the

sprocket-wheel and balance-wheel mounted thereon, the sprocket-chain connecting said sprocket-Wheels, the transverse shaft provided with a sprocket-Wheel, the chain connecting said last-mentioned sprocket-wheels, said transverse shaft having the sprocketpulleys 12 and 13 mounted on its outer ends,

in combination with the loose sprocket-pulleys 14 and 15 and the endless sprocket-

chain belts

18 and 19, provided with the paddles 20, substantially as and for the purpose set forth.

2. A propeller for boats, comprising the main driving-shaft, the sprocket and ratchet wheels fixed thereon, and having the drums provided with pivoted pawls, and means for intermittently operating said drums, in combination With the counter-shaft and the transverse shaft in operative connection with the said main shaft, and the sprocket-Wheels on said transverse shaft, which wheels are in operative connection, by means of sprocketchains,with loose sprocket-wheels,said chains being provided at suitable intervals with paddle-blades, substantially as and for the purpose set forth.

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