UNITED STATES PATENT OFFICE.
JOSEPH PEEVY AND A. SANBORN, OF BANGOR, MAINE.
SHIP S WINDLASS.
Specification of Letters Patent No. 17,633, dated June 23, 1857.
To all whom it may concern:
Be it known that we, JOSEPH PEEVY and ABRAHAM SANBORN, of Bangor, in the county of Penobscot and State of Maine, have invented a new and useful Improvement in Windlasses; and we do hereby declare that the following is a'full, clear, and exact descri tion of the construction and operation of t e same, reference being hadto the anneXed drawings, forming part of this speciication, in which- Figure 1 is a side view of the windlass. Fig. 2 is a top view of the same. Fig. 3 is a vertical section on xx. Fig. 4 is a vertical section on line y y.
Similar characters of reference in the several figures denote the same part.
The nature of our invention consists in an adjustment of the attachment of the pawls as will be hereinafter described, for the purpose of regulating the rapidity of rotation of the windlass.
In the drawing W is the windlass, R its ratchet wheel, L the lever and P P1 the awls attached, the one above the levers fu crum f, and the other below, so as to produce a rotation of the windlass on the depression of either arm of the lever.
The pawls P P1 are hung upon the slide pieces a al, capable of simultaneous movement in op oslte directions by the o )posite threads of b1 of screw c passing t rough them. This serves to adjust the distance of the points d d1 above and below the fulcrum of lever L, so as to produce the greatest rotation of the windlass when the slides have their maximum separation and causing the rotation to diminish as the slides ap )roach each other. This movement of the slides is effected by turning crank C.
We disclaim the mere lacing of the awls 1bove and below the fulcrum of the ever,
What We do claim is# The attachment of the pawls to the slides gi l operated as and for the purpose speci- In testimony whereof, we have hereunto signed our names before two subscribing witnesses.
JOSEPH PEEVY. ABRAHAM SANBORN.
