IMPRQVEMENT EN STEERlNG APPARATUS.
Specification forming part of Letters Patent No.143,200, dated September 23, 1873; application filed August 22, 1873.
To all whom it may concern:
Be it known that I, WlLLIAM E. THoMAs, of Queenstown, in the county of Queen Anne and State of Maryland, have invented a new and Improved Steering Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part. of this specification, in WhlCll- Figure 1 is a plan view, and Fig. 2 a side elevation, showing the peculiar features of my invention. a y
The invention relates to the means by which boats, ships, or vessels are steered, and will be first fully described and then clearly pointed out in the claims.
A represents an upright rising from the platform B, and receiving in suitable bearin gs the shafts O D. On the revolving drive-shafts G are made fast the ordinary hand-wheel E and the large spur-wheel F, the latter gearing with a pinion, F, on the other shaft D, which is journaled in a second post, A On this shaft D, and between the posts A A is placed a spur-wheel, G, which gears with two subjacent wide pinions, H H. The latter turn on guiderods h h at one end, while they are made fast to reversely-threaded screws K K at the other. These screws work in nuts formed in posts A A and are connected by a chain, L, which passes around a sprocket-wheel, M, madefast on the top of rudder N. Where the screws are not on a level with the sprocket-wheel,the chain is made longer and passed over suitable intermediate frictionpulleys. The rudder N is subjacently inclined upward toward the front, and provided with lon hooks or hingepintles n a, which work in eyes a n on the frame of the boat, so that the rudder will not only turn horizontally, but when it strikes an obstacle will rise over it.
The operation is as follows: When the helmsman wishes to turn the boat in its course he rotates the hand-wheel, which, with theintermediate mechanism, causes one screw to ad- Vance toward, and the other to withdraw from, the rudder, thus turning the same with great ease, quickness, and screw-power.
Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is
l. The combination, with a rudder, N, of the sprocketwheel, chain, and reverselythreaded screws rotated in opposite directions, as and for the purpose set forth.
2. The combination, with the reverselythreaded screws of a steering mechanism, of the wide pinions H H made fast to their ends, rotating as well as sliding on. guide-rods h h, and operated by a spur-wheel, (1, as and for the purpose specified.
