mnaswes Q lia /c71 0? UNITED STATES PATENT OFFICE.
ONSLOW' STUART, OF CHILMARK, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO BER-IAH T. HILLMAN, OF SAME PLACE.
RUBBER-LOCK.
SPECIFICATION forming part of Letters Patent No. 444,028, dated January 6, 1891.
Application filed May 4,1889. Serial No. 309,664. (Model-l To all whom it may concern.-
Be it known that I, ONSLOW STUART, a citizen of the United States, residing at Ohihnark, in the county of Dukes and State of Massachusetts, have invented a new and Improved Rudder-Lock, of which the following is a deseription.
Said invention is illustrated by drawings now on file at the Patent Office, in which- Figure 1 is a side view of a rudder attached to the stern-post of a vessel, showing the manner in which the rudder-lock may be applied. Fig. 2 is a view of the rudder-lock.
Similar letters apply to similar parts in each figure.
The rudderA is attached or hung to the stern-post B by the pintles O O, which are inserted in and passed through the gudgeons DD.
The rudder-lock is formed by the arm I), joined to the arm aby a hinge O. The arm a, may be attached to the rudder A, leaving the arm I) movable, said arm b being kept apart from the arm a by a spring d. This spring may be of metal and in the form of a spiral, as shown in the drawings, or may be of any other material and. in any other form now known to be capable of accomplishing the same object. WVhen the rudder is h ung, e e will press against the under side of the gudgeon D and against the pintle c and hold the rudder in place. The arm a maybe fastened to the stern-post B above the gudgeon D, so that when the rudder is hung e 8 will rest upon the head of the pintle c and hold the rudder in place. The projections e e serve to press against when itis desired to unlock the rudder, and in large locks such as would be applied to large vessels as means of attaching fastenings to hold the look, so as to permit the rudder to be unhung.
hat I claim as my invention, and desire to secure by Letters Patent, is
1. A rudder-lock consisting of two hinged leaves or arms, one of which is adapted for attachment to a rudder or stern post, and an interposed spring for forcing the free arm into engagement with the pintle and gudgeon.
2. A rudder-lock consisting of two hinged leaves or arms, one of which is adapted to be secured to the rudder or stern-post, its fellow having lugs or projections thereon to atford greaterloearing-surface, and having a rod projecting from its inner face and surrounded by a spiral spring, the fixed arm having aperforation for the passage of the rod when the leaves are closed.
