IMPROVEMET IN PROPELLING BOATS.

The Schedule referred to in these Letters Patent and making paxt of the sama.

To all whom it may concern:

Be it known that I, DANIEL J. Ross, of Havre de Grace, in the county of Harford, and State of Maryland, hav`e invented a new and useful Improvement in propelling-Boats; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledin' theart to make and use the same, reference being had t-o the accompanying drawings, forming part ofthis specification.

This invention relates to a new and useful improvement in propelling boats through the water, more especially designed to be applied to small boats, or those which are usually propelled by oars, and consists in driving a propeller-wheel at the stern of the boat, by

means of a cord and pulleys, by a crank or cranks,

4,turned by hand, as will be hereinafter more fully described.

.In 'the accompanying plate of drawings-v Figure l represents a longitudinal side view, with the side of the boat broken away, to show the drivingapparatus.

Figure 2 is a top or plan view.

Similar letters of' referenceindicate corresponding arts.

A is the boat.

Bis a propeller-wheel, on the end of a shaft, C, which passes through the stern, after the manner of the ordinary propeller-wheel shaft. Y

D represents a pulley or baud-wheel on the propellershaft.

E E represent stands, which are properly fastened together, and vare supported on the bottom of the boat.

F is a crank-shaft, supported by the stands E, upon which (between the stands) there is another pulley or band-wheel, G, which standsat right angles with the pulley D, as seen in tbe drawing. i

These pulleys lare grooved, and a round band is used, so that, although it makes a quarter turn, to

fit the position ofthe pulleys, there will be no danger of its running of the pulleys.

H i's the operators seat. I is the driving-band.

` To propel the boat, the operator ori boatman takes l 'hold of the cranks J J, and revolves the pulleys G,

and the propeller-wheel, byineans ofthe band I.

This is a direct application of power tothe boat, and is much more steady and etiectivc than when the' same power is applied by means of oars.

K is the rudder.

L is the tillerbar, which is connected by means of cords m m, with foot-levers n n, so that the` boatman, while he turns the cranks with his hand,"

purposes set forth. l,

DANIEL J. ROSS. Witnesses:
