PRDPELLING ATTACHMENT FOR BOATS.

SPECIFICATION forming part of Letters Patent No. $36,68 dated February 23,1886.

Application filed February 28, 1885. Serial No. 157,334. (No model.)

To-aZZ whom it may concern.-

Be it known that I, FRIEDRICH ZSOHIEG- NER, of Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Propelling Attachments for Boats, of which the following is a specification.

This invention has reference to an improved propelling attachment to boats, whereby the propelling-screw is operated by means of a comparatively simple mechanism that is.

worked by amotion resembling somewhat the motion of thebody in rowing; and the invention consists of a supportingframe attached to the bottom of the boat, a drivingroller provided with gear-wheels that are adapted to mesh alternately with pinions on a fly-wheel shaft or on alower auxiliary shaft, a reciproeating slide frame applied to the shaft of the roller and provided with rollers at the lower part, an actuating-band attached to the roller and adapted to be wound up in one or the opposite direction thereon, and mechanism by which motion is transmitted from the flywheel shaft to the auxiliary shaft and to the propeller-shaft, as will more fully appear hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of a boat with myimproved propelling attachment. Fig. 2 is an end elevation of my improved propelling attachment, drawn on a larger scale.

Fig. 3 is a vertical longitudinal section on line to as, Fig. 2; and Fig. 4 is a side elevation of the propelling attachment with parts broken away and the actuating-band in position for reversing the motion of the propelling-screw.

Similar letters of reference indicate corresponding parts.

A A in the drawings represent two upright standards, of cast-iron or other suitable material, which are rigidly secured to the bottom of the boat and connected by transverse bracerods a a. At the upper part of the standards A A are arranged bearings b I), for supportinga transverse shaft, B, to each end of which afly-wheel, B, is rigidly applied. The flywheel shaft B is provided between the upright standards A A with two pinions, d d, and intermediately between the pinions with a pulley, e. Below the fly-wheel shaft B is inclined slots f f of the supporting standards A when the frame 0 is raised or lowered by the action of the feet. To both ends of the roller D are attached gear-wheels d d, which mesh alternately with the pinions d d of the fly-wheel shaft B, and also with the pinions al of an auxiliary shaft, D that is supported in bearings Z) of the standards A A below the roller-shaft D. The lower part of the in clined frame 0 is provided with rollers g 9, that are retained by collars g and guided along rails g of a bottom plate, 9. Spiral springs Z connect the standards A with the slide-frame G, and serve to balance to some extent the weight of the frame and of the roller D, so as to facilitate the upward motion of the same. A belt, 6', extends from the pulley e of the fly-wheel shaft- B, to a pulley, 6 on the propeller-shaft E, which latter turns in bearings at the under side of the bottom of the boat,and extends through a stuttingbox at the stern to the outside, the propelling-screw E being applied to the rear end of the shaft E. A cross-belt, h, extends farther from a pulley, It, on the auxiliary shaft D to a pulley, 7L2, on the flywheel shaft, as shown in Figs. 2 and 3.

To the grooved actuating-roller D is rigidly attached the end of a stout band, F, made of canvas, leather, or other suitable material, the outerend of which may be provided with a suitable handle or handles. The band F is of such a width that it will readily wind around the central grooved part of the roller D. The person operating the propelling attachment sits back of the same, looking forward in the direction of the bow, with his feet resting on the lower part of the slideframe O and his hand grasping the band F. By pressing the slide-frame 0 forward so that its rollers move along the guideways of the bottom, its upper ends lift the shaft of the roller D in the slots ff of the standards, and move thereby the roller D in upward direction, so as to enable its gear-wheels cl (1 to mesh with the pinions d d of the fly-wheel shaft. At the moment when this is accomplished a backward pull is exerted on the baud F,whereby rotary motion is imparted to the roller D and the fly-wheel shaft B, which motion is transmitted by the pulley e, belt 6', and pulley e, to the propeller-shaft E and the propeller E, so that the boat is moved in forward direction. lVhen the band F is nearly unwound from the roller D, the pressure of the feet on the slide-frame O is relaxed, so that the latter isreturned into its former position by its own weight and the weight of the roller D and thrown in mesh with the pinions d of the lower shaft, D to which continuous rotary motion is imparted by the cross-belt h and the pulleys h If from the fly-wheel shaft in opposite direction to the rotary motion imparted by the band to the roller D, as indicated by the arrows in Fig. 3. As soon as, therefore, the gear-wheels d mesh with the pinions d of the shaft D the motion of the roller D is reversed and the band F wound up thereon ready for the next pull. The inclined slide-frame Oisthen again pushed forward by the feet, so that the gear-wheels d mesh with the pinions d on the fly-wheel shaft B, at which moment the band is again pulled back and unwound from the roller D, so that the rotary motion is imparted to the same and to the fly-wheel shaft. The pressure of the feet on the s1ide-frame is then relaxed-the roller lowered, the actuating-band wound up again by the motion of the lower shaft and V the intermeshing of the gear-wheels d d and pinions d (2 The fiy-wheels receive a sufficient momentum by the intermittent action of the band F to keep the fly-wheel shaft and the propeller shaft in continuous rotary motion during the time required for the rewinding of the actuating-band.

When it is desired to reverse themotion of the boat, the band F is pulled back to its full extent and allowed to wind up in opposite direction on the roller D, as shown in Fig. 4. In this position of the band the motion of the fly-wheel shaft and the propeller-shaft is reversed, and consequently the boat moved in backward direction. When a forward motion is again to be imparted to the boat, the band is again drawn back to its full extent and allowed to wind up in its former position on the roller D, as shown in Fig. 3.

The operating mechanism is preferably inclosed by a suitable protecting casing (not shown in the drawings) that incloses the gearing and prevents injury by contact with the gear-wheels.

The advantages of my improved propelling attachment for boats are, first, that the same can be operated by movements of the body which resemble those in rowing--that is to say, a motion of the feet alternating with the action of the arms; secondly, that this motion takes place regularly without overstraining the body, and is communicated uniformly to the propeller-shaft; thirdly, that the person actuating the propelling mechanism sits with his back toward the stern of the boat and looks forward, so as to be able to steer the boat at the same time, and, lastly, that the apparatus is comparatively simple and imparts a highlyincreased speed to pleasure-boats of all kinds.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
