Specification forming part of Letters Patent No. 198,053, dated December 11, 1877; application filed September 24, 1877. 4

To all whom it may concern.-

Be it known that I, WILLIAM W. SHOE, of Philadelphia, Pennsylvania, have invented a new and useful. Improvement in Devices for following is a specification:

The object of my invention is to construct a light and compact but effective steering and propelling device, adapted especially for small boats, canal boats, lighters, &c., an object which I attain in the following manner, reference being had to the accompanying drawing,

Figure 1 is a side view, partly in section, of my improved steering and propelling device; and :Fig; 2, a transverse section;

The rudder-post is made in two parts, A and A, connected together by'means of side plates at, which can slide on and are guided by 'each other, so that the lower part A of the post can manner as an ordinary rudder. Each of the pintles b is carried by a sleeve, (1, which emtically thereon, the upper sleeve being secured after adjustment by means of a set-screw or otherwise, and the lower one by means of a cam-lever, d, hung to the sleeve, and extenderated from the boat. The upper end of the adapted the tapering end of the tiller B, which may be seouredin position by means of a pin,

in'g-pulley, D, theshaft of which is furnished with crank-handles, to be operated by the 00 from the driving-pulley D to a pulley, E, on the-top of the shaft F by means of the belt f,

The shaft F is made in twoparts, the upper of which has its bearing in a bracket, g, projecting from the upper portion A! of the rudderits bearing in a frame, G, carried by the lower portion A of said post, the upper end of the said lower portion of the shaft F being of a square or angular section, and being adapted to the similarly-shaped interior of -a sleeve, h, secured to the lower end of the upper portion The particular construction of the propeller need not be described here, as it will form the subject of a separate application for a patent.

To the rear of the frame G is secured a plate,

P, which serves to aid thepropeller J in steer ing the boat when the-frame G is turned'to one side or the other.

The pintles b b are made adjustablevertically, in order that the device may be applied to boats having eyes at different distances apart, the upper pintle being first adjusted to the upper' eye, and the sleeve carrying the lower pintle being then released from the post A, by moving the cam-lever d in the direction of the arrow, Fig. 2, after which the sleeve is adjusted vertically to the desired position, and again secured by restoring the said lever d to its former position. I

The object of making the postA and shaft F in two parts, and connecting the parts of the post by the sliding plates at and the parts of the shaft by the sleeve h, is to permit the lower portion A of the post A and the frame Gr carried by the same to be adjusted vertically, so that the propeller J shall always be properly submerged Whether the boat be light or loaded.

By the use of the plates at, also, a space is provided between. the same for the reception of the bolt with which the stern of the boat is generally provided, and by which-it is suspended from the davits. Moreover, the plates, by coming in contact with the sides of the stern-post, prevent undue movement in either direction of the post A and the propellerwheel.

The raising and lowering of the lower portion A of the post A and the parts carried by the same may be readily effected from on board the boat by means of a cord or chain, y, and pulleys v v, the upper end of the cord being secured by passing it round a suitable cleat.

' compact packing of the device for storage or transportation.

Y The post A and its connections being removable from the boat, the device is not subjected to the risk of being damaged when the boat is not in use, or is lifted out of the water. Furthermore, it does not prevent the use of the ordinary rudder when it is desirable to propel the boat by sail or oars.

- I do not desire to confine myself to the beltand-pulley mechanism shown and described for operating the shaft F, as bevel-gear or an arrangement of levers might be substituted for the same in some cases. The pulleys and belt, however, are to be preferred.

, I claim as my inventi 0n 1. The combination of the propeller-wheel J, shaft F, and intervening gears with the post A, hung to pintles on the stern-post of a boat, so as to be readily turned on or removed therefrom, all substantially as and for the purpose set forth.

2. The combination of the pot carrying the propeller-wheel and shaft F, with the tillerarm B, carrying the driving appliances, all substantially as specified.

3. The combination of the post A, carrying the wheel J and shaft F, with the tiller-arm 13, carrying the device to which the power is applied, and rendered detachable from the post A, as specified. Y

4. The combination of the wheel. J and its driving mechanism, the post A, and shaft F, each made in two parts, connected together so as to permit vertical adjustment of the lower part in respect to the upper part, and a device, substantially as described, for retaining said lower part in the position to which itmay be adjusted.

5. The combination of the upper and lower portions A and A of the post A with the side plates a, serving to connect the two partstogether, all substantially as described.

6. The combination of the post A with sleeves d, carrying pintles b, and capable of being adjusted vertically on said post A, as set forth.-

7. The combination of the post A with the lower sleeve d and its cam-lever d, as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM W. SHOE.
