\VILBER S. SALISBI'RY, OF CHICAGO, ILLINOIS.
BOAT -PROPELLING APPARATUS.
QPECIFICATION forming part of Letters Patent No. 486,684, dated November 22, 1892. Application filed February 12,1892. Serial No. 4:21. NO del- To all whom, it may concern.-
Be it known that I, WILBER S. SALISBURY,
a citizen of thel'nited States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Boat-Propelling Apparatus, described and claimed in the following specification.
This invention relates to improvements in boat-propelling apparatus, and embraces a propeller-wheel and a motor for propelling small boats and launches, the said device being mounted upon or attached to a tube con taining a fiexibleshaft connecting the motor and propeller-wheel, which is swiveled to move with perfect freedom in any direction for steering or propelling a boat.
IIeretofore, so far as I am aware, the motor and screw-wheel have been dependent upon tical and useful manner independent of the rudder for steering and propelling in any direction required, thus producing a practical, useful, and novel device in navigation; This object is obtained by swiveling one end of the device to the stern of a boat, producing a combined propelling and steering mechanism, entirely taking the place and doing away with an form of rudder for steering purposes, and
is'therefore entirely independent of a rudder in its functions of propulsion.
In order that the description may be rendered more clear,I refer to the accompanying drawings, in WhICh"**- Figure 1 represents a side elevation of a bent tube inclosing a flexible coiled-wire shaft, as seen at the broken sections at both ends of the tube, also showing an electric motor and gear-casing atthe upper end thereof and a screw-wheel for propelling at the lower end. Fig. 2 represents one manner of mounting said device-to the stern-post of a small boat, which is accomplished by means of the ringclasps encircling the benttube and bolting the ends to a piece of board that has been shaped on one side to conform to the curve of the tube and then swiveling the said board resents the motor coupled to the gear, said gear being shown in section as mounted upon the short shaft. Fig. i represents a top plan view of the device as attached to a square stern, showing, also, the yoke and steeringropes. Fig. 5 represents the motor mounted on the tubing, with a small and a large gearwheel for operating the shat'ting.
In said drawings, A represents the electric motor suitably monnted'on the head-frame B. The head-frame B is cast in parts and formed to flt the end of the bent tube C, and both the top and under parts have lip-extensions for the purpose of supporting the tube at the neck. The parts are bolted together, clasped around the tube, thereby giving a strong support for the motor, gear-casing, and tubing.
Inside the tube G is a flexible shaft D, of coiled wire, extending throughout its entire length. On each end of the flexible shaft are suitably mounted short shafts journaled in metal boxes that are fastened within and at each end of the tube 0.
On the projecting end of one of the short shafts is suitably attached the screw-propeller wheel E, and between the propeller-wheel and the end of the tube is placed frictionrings F to relieve the thrust of propeller-wheel of undue friction against the end of the tube when working.
To the lower end of the tube are fins G G, made from sheet'metal and brazed on the .center of tube at top and under side to assist =in steering, but are not. wholly essential to the successful working of the device for the purpose of guiding the direction of the boat, as'the boat can be steered by the working ofthe wheel when the tube is thrown from port to starboard by' means of the yoke K, said yoke passing through the elongated opening in the under part of head-casting B. Projecting forward from the under side of the head B is a lug by which the casing lI, containing the gear-wheels, is bolted thereto. The armature-shaft and pinion-shaftare connected by the flange-couplings I.
I have shown in Fig. 3 one plan of gearing by double reduction for power purpose and in Fig. 5 I have shown a single-reduction gearing. Those two methods are for small high-speed motors; but when using a slowspeed motor of larger type I couple direct to the upper shaft J, thereby dispensing with the gear-wheels. Therefore I do not wish to limit myself to any one form of gearing, neither do I desire to limit myself to any one method of attaching my device to the stern of a boat, as I have already illustrated by Figs. 2 and 3 two plans.
By constructing and arranging the electric motor on the tube and connecting it by gearing With the propeller-wheel, as set forth, an adequate amount of flexibility will be attained between said motor and propellerwheel, whereby the wear on the parts will be reduced to a minimum, and all jerking or vibratory motion is taken up by the flexible shaft, thus insuring easy running, also a higher rate of speed, with maximum current rate of discharge, owing to the spring action of the shaft in the line of rotation.
\Vhen the circuit is closed, in starting, the spring action of the shaft enables the motor to get up its counter electro-motive force more speedily and with less danger of overheating the armature. Therefore there is the same advantage gained in constant runningviz., less heating of the armature. By this method of construction great advantages are gained in permitting the same form of construction being easily applied to the various forms of row-boats, canoes and hunting-boats, or even to small launches.
The use of the tubing partially filled with oil and inelosing the flexible shaft permits, of constant and copious lubrication of the shaft and journal bearings, reducing the friction and wear to a minimum, and prevents the access of dirt to the working parts. The spring of the flexible shaft relieves the motor and propeller-wheel of any sudden strain due to rapid starting or stoppingof the motor. A very important feature is prod need by the use of the flexible shaft in the tune, whereby the thrust of the wheel is borne by the tube, thereby relieving the motor from the evil effects that otherwise would occur. from the thrust of the screw-wheel when in motion.
Numerous slight changes might be made in the details of construction of my invention without departing from the spirit of my invention. Hence I do not wish to limit myself flexible shaft and giving motion therethrough to the propeller-wheel, substantially as de scribed.

Boat-propelling apparatus comprising a tube arranged and adapted to be pivotally connected with the stern of a boat, a flexible shaft within said tube carrying at its lower end apropeller-wheel, and a motor connected with said flexible shaft adapted to give motion thereto and to the propeller-wheel, substantially as described.
