Description

UNITED STATES PATENT OEEIcE.
NATHANIEL ROBBINS, JR., OF ROGKPORT, MASSACHUSETTS.
IMPROVED GUDGEON FOR BOOMS.
Specification forming part of Letters Patent No. 66,633, dated July 9, 1867.
To all whom it 'may concern:
Be it known that I, NATHANIEL RoBBINs, Jr., of Rockport, in the county of Essex, in the State of Massachusetts, have invented Va new and Improved Connection or Gudgeon for Booms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and showing one application of my improvement on board vessels, in Which- Figure l` is a perspective View; Fig. 2, a horizontal view; and Fig. 3, a vertical section.
Similar letters refer to similar parts, as follows:
A, portion of mast, to which the boom is attached, B, lower end of boom; C, collar or span clasping the mast and forming a support for the socket D, piutle E, and universal joint F, which together form the gudgeon which I claim as my improvement. By this device, the friction usually attending the motion of a boom against a mast is very much lessened, and the strain brought upon the throat and jaws or piutle of a boom, as ordinarily arranged, by the tendency of a sail full in the wind to roll a boom over on its axis, is entirely avoided. i
By making the socket D and piutle E longer than would be otherwise necessary, I am enabled to give a vertical motion to the boom, which may at times be valuable. In construction I bring the weight of the boom upon the socket D, and not upon the piutle E.
What I claim as my invention, and desire to secure by Letters Patent, is
1. The use of the socket D and the pintle E, as a bearing for a boom and connection with a mast, substantially as described.
2. The construction and arrangement of the boom-joint or connection, substantially as described.
NATHL. ROBBINS, JR. Witnesses:
