HENRY N. STAATS, OF AUBURN, NEW YORK.

MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 240,475, dated April 19, 1881.

I Application filed January 18, 1881. (No model.)

To all whom it may concern Be it known that I, HENRY N. STAATS, of Auburn, in the county of Cayuga, and in the State of New York, have invented certain new and useful Improvements in Mechanical Movements and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in Which Figure 1 is a perspective view of the rear portion of a boat provided with my propelling mechanism. Fig. 2 is alike view of the mechanism employed for rotating the propellershaft. Fig. 3 is a plan view of the upper side of the reversing-gear; and Figs. at and 5 are, respectively, perspective views of the single and double operating-cranks.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to render practicable the use of a screw-propeller upon small boats; and it consists, principally, in the means employed for rotating the propeller-shaft, substantially as and for the purpose hereinafter specified.

It also consists in the construction of the cranks employed for operating the propelling mechanism, substantially as and for the purpose hereinafter set forth.

In the annexed drawings, A represents a short shaft, which is journaled horizontally Within a suitable frame, 13, and is provided at its longitudinalcenter with a spur-pinion, G, and upon each side of the same with a bevelgear, D. Said shaft is capable of longitudinal movement within its bearings, and is adjusted to and secured in position longitudinally by means of a lever, E, which is pivoted at one end upon a fixed support and at its center to one end of said shaft, while at its opposite free end said lever rests upon and may be moved horizontally over a bar, F, that has upon its upper side 2. lug, j, which engages with said lever when moved to either limit of its motion, and locks the same in place.

Motion is imparted to the shaft A by means of a spur-gear wheel, Gr, which is secured upon a shaft, H, that is journaled within the upper portion of the frame 13 in such position as to cause said wheel to mesh with the pinion G.

Said shaft H is provided upon its projecting ends with cranks I, by means of which it may be rotated.

The frame B is secured to the bottom K of a boat of usual construction, preferably at a point at or in rear of its longitudinal center, with its shafts A and H arranged at a right angle to the keel, after which the front end of the propeller-shaft L is journaled within-the rear end of the frame midway between, but in rear of, the bevel-gears D and D, said shaft L being arranged in a line extending from the axis of the shaft A to the stern K near its intersection with the keel k. The front end of the propeller-shaft L is provided with a bevelpinion, Z, which is adapted to mesh with the bevel-gears D and D, either of which latter may be thrown into engagement with said pinion by moving the shaft A longitudinally in the right direction. The rear end of the propeller-shaft L is provided with a screw-propeller, M, which may be caused to revolve in either direction by the rotation of the crank-shaft H,

.and the direction with which the latter is revolved with relation to the rotation of said propeller may be changed at will by shifting the shaft A longitudinally within its bearin gs, so as to cause one or the other of the bevelgears D to mesh with the pinion i.

In consequence of the shifting mechanism described the operator is enabled to sit with his face toward the bow or stern and move the boat in either direction, or to reverse the direction of the cranks, so as to bring into play a different set of muscles, Without changin g the direction of the propeller.

The cranks I are each provided with two or more sockets, t, for engagement with the end of the shaft H, so as to enable the operative length .of the crank to be varied to suit the convenience of the operator, while upon its outer face, at its end, each crank has pivoted an egg-shaped button, 6, of suitable size to be grasped by the hand.

In order that two persons may be able to operate the mechanism at the same time, an extra pair of cranks, I, is provided, each of which has pivoted upon its outer face, atits outer end, a short bar, i that has pivoted at each end a button, 43, in all respects like that before described. The length of such pivoted baris such as to'enable each button 4." to be grasped without interference with the hand of the person using the opposite button, andin use said bar maintains a general horizontal position, oscillating slightly in each direction therefrom as the positions of the operators change.

Having thus fully set forth the nature and I merits of my invention, whatIclaim as new is- 1. As ameans for rotating the propeller-shaft L, the shafts A and H, spur-pinion O, bevelgears D and D, gear-wheel G, bevel-pinion l, and cranks I and I, in combination with each other, the supporting-tram e'B, and said shaft L, substantially as and for the purpose specified.

2. The cranks I and I, provided at or near the 15 HENRY N. STAATS.
