JOHN E. MANAS, OF PRINCETON, NEW JERSEY.

PROPELLER-ROTATING DEVICE.

Application filed April 5, 1920.

1 0 all whom it may concern:

Be it known that 1, JOHN E. Manes, a citizen of Greece, residing at Princeton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in Propeller-Rotating Devices, (Case A,) of which the following is a specification.

This invention relates to propelling means for boats and the principal object of the invention is to provide manually operated means for driving a propeller.

Another object of the invention is to provide means whereby the actuating means are driven by a motion somewhat similar to that used in rowing a boat.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illus trated in the accompanying drawings and specifically pointed out in the appended claims. In describing my invention in detail, reference will be hadto the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view through a boat provided with my invention.

Fig. 2 is an end view of one of the supporting frames and its associated parts.

Figs. 3 and 4 are detail views.

Fig. 5 is a plan view of a modification.

Fig. 6 is a section on line 6-6 of Fig. 5.

Fig. 7 is a detail view of this modification.

Referring to the drawings 1 indicates the boat, 2 the propeller shaft passing through said boat and 3 the propeller which is connected to the projecting end of said shaft. The other end of the shaft carries a flywheel 4. A pair of upright frames 5 are arranged in the boat and each frame has journaled therein a shaft 6 which carries a beveled wheel 7 and a sprocket wheel 8. The propeller shaft 2 is provided with a pair of beveled gears 9 which mesh with the gears 7. A crank shaft 10 is also journaled in each frame and this shaft carries a sprocket wheel 11 which is connected with the wheel 8 by the chain 12. A horizontal bar 13 has its ends connected with the cranks of the crank shaft and this rod carries a number of cross bars 1e by which the rod may be reciprocated to cause the crank shafts to rotate.

As shown the bars 14 project across the boat Specification of Letters Patent.

and each bar is adapted to be grasped by two men, one on each side of the rod 13. By swaying their bodies back and forth, similar to the motion used in rowing boats, the men will move the rods let back and forth and thus rotate the crank shafts. This movement of the crank shafts will be communicated to the shafts 6 by means of the chain and sprocket wheels and as these shafts 6 are geared to the propeller shaft the propeller will be rotated to drivethe boat.

I provide means whereby the cross bars 14; may be detachably connected with the rod 13 so that only those bars in use may be placed in engagement with said rod. Such means may consist of holes formed in the rod to receive the bars or any other desired means may be used.

In the modification shown in Figs. 5, 6 and 7 the rod 13 is moved by the bar or bars 14E which are carried by the stationary bars 15, located on each side of the rod 13. The inner ends of the bars 14: are provided with rounded parts 16 which engage sockets 17 formed in the rod 13 and these rods 14 pass through openings 18 formed in the bars 15.

In this form of the invention each bar 1% is actuated by a person and the bar is moved similarly to an car. This movement of bars will move the rod 18 back and forth so as to rotate the cranks and thus impart movement to the propeller. The other parts of the form shown in Figs. 5, 6 and 7 are similar to the parts shown in the first form. In the second form the action is more like the. movement used in rowing a boat. It will of course be understood that any numer of rods 14 may be used according to the size of the boat and the number of rowers. I prefer to make these rods detachable so that they may be laid aside when not being used.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. Propelling means for boats comprising a propeller shaft, a propeller thereon, upright frames in the boat, a stub shaft journaled in the lower part of each frame, gears connecting each shaft with the propeller shaft, a crank shaft journaled in the upper part of each frame, means for driving the stub shafts from said crank shafts, a longitudinally extending rod connected with the cranks of the crank shafts, and handles engaging parts of said rod for reciprocating the rod.

2. Propelling means for boats comprising a propeller shaft, a propeller thereon, upright frames in said boat, a stub shaft journaled in the lower part of each frame, gears connecting said shafts with the propeller shaft, a crank shaft journaled in the upper part of each frame, sprockets and chains connecting said crank shaft with the stub shafts, a longitudinally extending rod connected with the cranks of the crank shafts, said rod having sockets therein, supporting bars arranged adjacent the longitudinal rod and having openings therein and handles passing through said openings and having their ends engaging the sockets in the longitudinally extending rod.

In testimony whereof I affix my signature.

JOHN E. MANAS.
