PROPELLING APPARATUS FOR BOATS.

SPECIFICATION forming part of Letters Patent No. 637,051, dated November 14, 1899.

Application filed m 15, 1899.

To all whom it may concern.-

Be it known that I, CARL WASEK, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Propelling Means for Boats; and I do hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to means for propelling small boats, and it has reference particularly to that class of such propelling means which depends upon man-power for its actuation. The invention consists in the combination and arrangement of the parts of a mechanism of this nature, substantially as will be hereinafter pointed out and finally embodied in the clauses of the claim.

The invention is fully illustrated in the accompanying drawings,'wherein Figure 1 is a top plan View of a portion of.

a boat provided with my improved propelling mechanism. Fig. 2 is a longitudinal sectional view, somewhat enlarged, of what is shown in Fig. 1; and Figs. 3, 4, and 5 are views of certain details involved in the invention.

Projecting upwardly from the bottom a of the boat, being secured thereto, is a pair ofstandards 17, forming bearings for a horizontal shaft 0, that extends transversely of the boat and is held in place in each hearing by means of a plate d, surmounting each standard and extending over the shaft. Said standards project upwardly through an opening 8, provided in the floor f of the boat. The edges of said opening are shown as being broken away in Fig. 1 to clearly show in elevation the construction of the shaft-driving mechanism. Said shaft carries a pair of spaced drums g, which are loosely mounted thereon and which carry on their adjacent faces spring-actuated pawls h, that engage the teeth of ratchetwheels "i, which are keyed on the shaft 0. Forward of the shaft thereis disposed, being supported upon the bottom of the boat, another pair of standards 3', said standards affording bearings for another shaft is, which Serial No. 723.890. (No model.)

carries segments Z, upon the periphery of each of which is secured a strap or band m, which extends rearwardly and is Wound about and a secured to the periphery of one of the drums g. Each strap or band we may be adjustably secured to either the drum or the segment. I have shown it as adj ustably secured to the segment by means of a thumb screw 12, that is mounted in the periphery of the segment and penetrates a longitudinal slot 0 in the band. The segments are swung by means of cranks p, which are suitably secured thereto for movement therewith and which carry foot-treadles g. It will be seen that by oscillating the segments Z the consequent rotation imparted to the drums Q will effect, through the pawls and ratchet-Wheels, the rotation of the shaft 0.

In order to effectually produce a continuous movement in the shaft 0, I provide means for working the segments Z alternately, said means consisting of another band or strap 1", secured to and passing around the peripheries of the drums g alongside of the other straps, and also extending around sheaves s, that are journaled in uprights t, suitably sustained between the fioor f of the boat and one of the thwarts u.

'12 is a propeller-shaft carrying a propeller w and journaled at its forward end in a pair of standards y, that rest upon the bottom of the boat, that portion of said shaft between the standards y being formed into a compound or reversely-threaded worm z. Said Worm is adapted to be engaged by either one of apair of worm-wheels a b, that are rigidly secured upon a sleeve 0', said sleeve being keyed for movement longitudinally thereof upon the shaft 0. It should be remarked that the wormwlieels a and b have their teeth cut right and left handed, respectively, being adapted therefore to rotate in opposite directions the propeller-shafto. In order to move the sleeve 0 on the shaft 0 so as to disengage the one of the worm-wheels and engage the other of said worm-wheels with the worm z, and thus reverse the mechanism, I have provided a shifting lever 01, that is fulcruined in a suitablysupported bracket e and is curved about said sleeve, being provided with diametrically-opposing lugs f,which engage in a groove g, formed between the worm-wheels. The

free or handled end of the lever projects forwardly, so that it can be conveniently reached by the operator from the thwart h, which it is intended he should occupy. A double stop 70', consisting of an elongated plate of metal bent into substantially the shape of the letter M is secured, if desired, to the flooring f, beneath the lever, so as to maintain the latter in either of the two positions where it effects an engagement between one of the wormwheels and the worm.

If it is desired to employ instead of the propeller side wheels, the shaftc may be extended beyond the Walls of the boat and carry such side Wheels, the same being shown in dotted lines in Fig. 1 and indicated by the reference character 1', each being supported in an auxiliary bracket j, projecting outwardly from the boat.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a mechanism forpropellingboats, the combination of a suitably-supported revoluble shaft,drums loosely mounted on said shaft, ratchet-wheels secured on said shaft, springactuated pawls carried by said drums and engaging the ratchet-Wheels, means for operating said ratchet-wheels, a suitably-journaled shaft disposed transversely with reference to said first-named shaft, a propeller carried by said last-named shaft, a compound worm carried by the propeller-shaft, a sleeve keyed onto said first-named shaft, a pair of worniwheels having their teeth reversely cut and either being adapted to engage said worm, said Worm-wheels being mounted on said sleeve, and means for shifting said sleeve on the shaft, substantially as described.

2. In a mechanism for propelling boats, the combination of a suitably-supported revoluble shaft,drums loosely mounted on said shaft, ratchet-Wheels secured on said shaft, springactuated pawls carried by said drums and engaging the ratchet-wheels, another shaft, segments having hearings on said shaft, bands connecting said segments and the drums, means for oscillating said segments, another band connected at its ends to each drum, sheaves, said last-named band passing over said sheaves, a propeller, a suitably-journaled propeller-shaft carrying said propeller, a compound worm carried by said propeller-shaft, a sleeve keyed onto said first-named shaft, a pair of worm-wheels having their teeth reversely cut and either being adapted to engage said worm, said worm-wheels being mounted on said sleeve, and means for shifting said sleeve on the shaft, substantial] y as described.

In testimony that I claim the foregoing I have hereunto set my hand this th day of June, 1899.
