FRANCESCO MONTIGLIO, OF GLASTONBURY, CONNECTICUT.

BOAT.

Application filed March 10, 1914. Serial No. 823,728.

To all whom it may concern:

Be it known that I, FRANCESCO MONTI- GLIO, a citizen of Italy, residing at Glastonbury, in the county of Hartford and State of Connecticut, have invented'new and useful Improvements in Boats, of which the following is a specification.

This invention relates to boats and particularly the propelling mechanism therefor, the object of the invention being to provide simple mechanism for actuating a screwpropeller at the stem of the boat, the said mechanism serving to apply continuous power to the propeller shaft and the initial element of the propelling mechanism being adapted to be driven either by a pedal crank shaft or by any suitable motor.

A further object of the invention is to combine with such initial driving element, and an operators seat arranged adjacent thereto, a steering rudder of novel construction arranged in the bow of the boat and operable by a hand controlled element also arranged adjacent to the operators seat.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a vertical longitudinal section through a boat, showing the same equipped with the driving and steering mechanism of this invention. Fig. 2 is a horizontal section through the same taken above the propelling mechanism. Fig. 3 is a detail horizontal section through the stern of the boat taken about in line with the propeller shaft which I is shown in elevation. Fig. 4 is a detail horizontal section through the bow of the boat showing the rudder. Fig. 5 is a vertical cross section through the boat taken about midships.

The boat which is generally designated at A may be of any desired size and general construction and is provided with the usual propeller 2 at the stern thereof, the same being mounted on a propeller shaft 3 extending through a shaft hole in the stern of the boat and being provided upon its inner end and within the boat with a bevel gear pinion 4 the purpose of which will appear.

Arranged in front of the forward extremity of the propeller shaft and perpendicular to said propeller shaft is a countershaft 5 on which are mounted two bevel gear Specification of Letters Patent.

wheels 6 which rotate in opposite directions and both. of which mesh with the pinion 4 at opposite sides of the latter. outer sides the bevel gear wheels 6 are pro vided with ratchet faces or teeth 7 disposed inreverse directions as shown in the drawings, said ratchet faces being engaged by pawls 8 arranged at opposite sides of the wheels 6 and being slidable on a transverse pin 9 on a pawl actuating lever 10 which has,

its rear end j ournaled and fulcrumed on the .countershaft 5, such lever being adapted to move in a substantially vertical plane. A contractile spring 9 connects the pawls 8 and holds them in engagement with the ratchet faces 7. It will be observed that as the lever 10 moves downwardly, one of the pawls will engage with one of the gear wheels 6 to revolve said wheel in one direction and when the lever moves in an upward direction, the other pawl carried thereby engages the ratchet teeth of the other bevel gear wheel-6 thereby rotating the last named wheel in the opposite direction to the first named wheel. Continuous rotary motion is imparted in this way to the bevel gear pinion 4 and therefore the propeller shaft and propeller.

At its forward end the lever 10 has pivotally connected thereto a pitman 11 which is pivotally attached at its opposite end at the point 12 to a rotary spur gear wheel 13. This wheel 13 is mounted on a short transverse shaft 14 and meshes with and is driven by another spur gear wheel 15 fast on a crank shaft 16 shown as provided with suitable cranks and pedals 17 adapting it to be propelled by the foot power of the operator who occupies a seat 18 adjacent to said crank shaft. It will of course be understood at this point that the crank shaft 16 may be driven by any suitable motive power.

A section 19 of the bow of the vessel is utilized as a rudder, said section being normally flush seated in a recess 20 of corresponding size and shape in the bow of the boat. The said wedge-shaped rudder or boat section 19 is fast on the lower end of a rudderpost 21 which is provided with a pinion 22 fast thereon and meshing with a sector 23 mounted on a steering shaft 24 shown in the preferred embodiment of this invention as provided with a hand controlled or steering wheel 25. This wheel is 'arranged in convenient reach of the operator On their 7 while sitting in the seat 18 where he is also enabled to operate the propelling mechanism by means of his feet, and places the entire control of the propelling and steering mechanism within easy reach of the operator.

26 designates a hood or housing which fits over the lever 10 and the pitman 11 and also forms a support for the seat 18 above reand meshing with said pinion and provided on their outer sides with ratchet faces, a footpropelled crank shaft adjacent to the bow of the boat hull, a crank wheel geared to and rotated by said crank shaft, a transmission lever journaled at its rear extremity on said countershaft between said bevel gears, a pin carried by said lever, pawls slidable on said pin at right angles to said lever at opposite sides of the latter and cooperatingwith the ratchet faces of said bevel gears, a contractile spring connecting said pawls,

and a pitman connecting the forward end. of

said transmission lever with the crank pin of said crank wheel.

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

FRANCESCO MONTIGLIO.
