IMPROVEMENT IN unav-BOATS.

Specification forming part of Letters Patent No. 116,024, dated .lune 20, 1871.

l To all lwhom it may concern:

Be it known that I, HENRY CLENNY, of' Gallatin, in the county of Sumner and State of Tennessee, ha ve invented certain Improvements in Boats for Transporting Freight, Passengers, Sto., of which the following is a specifistructed on my plan, and Fig.' 2 is a side elevation of the same.

In the drawing, A represents the hull or body of my boat, which, in its' general form, resembles an ordinary hat-boat or scow; it being of a rectangular form, with straight sides. Instead, however, of the usual flat bottom, with two inclined ends, I divide the under side of my boat transversely into four faces, a, b,

' c, and d, which shouldv be of about the fonowing` proportions: The one at the bow eight feet in length, with an inclination of about fifteen degrees 5' the second, seventeen feet in length and horizontal 5 the third, eighteen feet in length, with aninclination upward toward the stern of from two to four degrees; and the last seven feet in length, with an inclination of about twelve or thirteen degrees. These faces are inclined fore and af't only, and are allhorizontal in their transverse section. The boat thus constructed I have found in practice to be easily propelled and steered, both when light and when loaded.

In loading the boatthe weight. should be placed principally on the forward portion,

above the rear part'of face b, as it depressesl `the forward end mainly and givesto the boat 4 the best poise orposition in the water. 0n

the boat thus constructed I place an overhanging deck of the form shown, and on the rear part of this deck I mount a'vertioal shaft, C, and provide it with a sweep, D, and a large lbevel cog-wheel, E. In rear of the shaft C I mount a horizontal shaft, F, and secure thereon a large wheel, G, and a bevel-pinion,H, the latter arranged to gear into wheel E, as shown.

lower the other.'

`On-the deck I mount a long horizontal shaft, I, with its rear end extending out over the stern, and to the forward end of this shaft I secure a pinion, J, gearing into wheel G, and to the rear end of the shaft secure a bevel -pinion, K. To the stern I secure projecting arms d,and in these arms mount a horizontal transverse shaft, L, provided with two loose bevel- I pinions, Maa-nd N, which gear into opposite sides of pinion K, so that the pinion Will turn them in opposite directions. To the outer end of sha-ft L I attach a paddle-wheel, O, which is thus brought behind one of the rear corners or quartersot' the boat. 0n the shaft L, between the wheels M and N, I place a' sliding clutch, P, which is prevented from turning by a spline, t', on the shaft, and which may be engaged with eitherv the wheel M or N, according as it is desired to have the shaft and thel paddle-wheel turn forward or backward. A hand-lever, R, mounted in a suitable support, is connected with clutch P for convenience in shifting the same. The sweep, being drawn around by means of a horse attached thereto,

sets the gearing in motion and turns the paddle-wheel, 'which propels the boat forward or backward,accordingto whichof the two wheels the clutch is engaged with. To provide for steering and directing the boat in its course I pivot to the stern, on the opposite side to the wheel, a large oar or sweep, S, as shown.

I have found in practice that a boat fifty feet in length, constructed on my plan, may, when loaded, be propelled with ease and at a considerablev speed, by a single horse` and that it may be, readily steered and handled by a' single man.V 1

My boat being possessed of theabove qualities, and being, moreover, constructed at a small expense, will be found of great-service in many places as a ferry-boat or a transport for freight. ferry purposes I provide it with suitable railings, and also with two platforms, T, hinged to the sides opposite each other, and connected by a rope passing around a windlass, U. The windlass, being turned, raises one of the platforms, and at the same time lowers the other; or, by fastening up either of the platforms, the windlass may be used lto raise or When arrangedin this man-g PATENT QFFICE.

When the boat is to be used for 11er one man can readily handle the platforms of the boa-t, and connected by a rope or. chain when landing or starting the boat. to a windlass, U, substantially as described, Having thus described my invention, what whereby one is raised as the other is lowered. I claim is- HENRY GLENNY.
