HENRY B. WILLIAMS, or RooHEsTEa'Nnw YORK, ASSIGNOR on TWO- THIRDS 'ro L. A. JEFFREYS, or SAME PLACE.
PROPELLING APPARATUS FOR VESSELS.
SPECIFICATION forming part 5: Letters Patent No. 367,125, dated July 26, 1887 f Application filed November 16,1886. SerialNo. 219,066. (No model.) v
To all whom it may concern:
Be it known that I, HENRY B. WILLIAMs, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Propelling Apparatus for Boats; and I do declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.
My improvement relates to propelling apparatus for small steam-yac'hts, and is also adapted to larger steam craft' It is of that kind where a bracket or frame is hinged at the inner end to rise and fall, and to which is attached a shaft and propeller which rise and fallwith the same, the shaft having auniversal coupling by which it can receive rotary motion at all angles, as hereinafter described. In the drawings, Figure 1 is a longitudinal metallic arm of considerable length, provided with right-angled bearings a a,through which runs the shaft B, having at its outer end an ordinary propeller, C. At the inner end of the frame is an arm, I), which stands at an obtuse angle and serves as a stop, striking against a shoulder, c, of the boat to limit the fall of the frame. At the inner end are also two side pivots or journals, 6 e, that rest in suitable bearings of the boat and serve as the attachments for the frame and allow it to turn up and down. The bottom dot the frame is made thin edged,forming a sort of knife or cutter that will out through weeds, and the outer end,f, is bent slightly upward to'inclose the lower edge of the propeller. Theinner end of the propellershaft B has a universal couplingjoint, 9, which connects it with the main shaft B,so that the propeller can receive rotary motion at whatever angle the frame may run.
E shows the boat having a center space or slot, h,on the under side and in the stern-post,
to allow the frame to rise and fall therein, and
at the rear of this slot is an enlarged space, h,
for the propeller to enter when raised. .In Fig. 2 the apparatus is shown attached to the boat some distance in from the, rear end, in
which case the space h has an enlarged inclined opening, h, at the rear to allow reaction against the water when the propeller is running high.
In Fig. 1 the apparatus is set at the rear end of the bolt,so. that the propeller acts directly outward. by a cord or chain, 70, running on a Windlass or any other suitable device.
This device is specially applicable to small steam-yachts, and it is designed to lower the propeller and let it hangloose under the boat. It is limited in the down movement by the arm b striking against the shoulder c. In passing over obstructions the bottom of the frame acts like a runner, and in passing through weeds or other light obstructions the bottom will act as a cutter, so that they can separate to prevent clogging the propeller. It is particularly adapted to inland waters encumbered by weeds. \Vhen drawn up, the apparatus strikes into the slot made for its reception like a center-board in its well.
Having described my invention, I do not claim simply and broadly a propeller at the rear of the boat capable of being raised and lowered at different heights; but
What I claim as new, and desire to secure by Letters Patent, is
Thepropelling apparatus described, consisting of the frame constructed with athin-edged bottom with bearings for the attachment of the propeller-shaft and propeller, with an inclined arm at the inner end forming a stop, and with side pivots by which it is attached to the bottom of the vessel, as set forth.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
HENRY B. \VILLIAMS. W'itnesses:
R. F. Oseoon, WM. J. MCPHERSON.
The apparatus is raised or lowered
