Description

M. BRYANT. I Improvement in Windlasses.
Patented. July 30, 1872.
gunman Wtmmi xflwwwiof MELANGTON BRYANT, OF NORTHPORT,NEW YORK.
, IMPROVEMENT m WINDLASSES.
Specification forming part of Letters Patent No. 129,927, dated July 30, 1872.
Specification describing a new and useful Improvement in Winches, Windlasses, &c., invented by MELANGTON BRYANT, of Northport, in the county of Suffolk and State of New York.
My invention consists of the attachment of the pawl-leverfor turning the drum of a windlass or winch to the ratchet-wheel or disk by i a kind of yoke or frame, embracing both sides of the wheel,and confined upon it by sectional annular flanges, fitting in annular grooves in the disk, and sliding around the disks-in said grooves, for raisin g the pawl, but binding 7 therein when the pawl is forced against the drum.
Figure 1 is a sectional elevation of a windlass constructed accordingto myimprovement, the section being taken on the line .00 00 of Fig. 2. Fig. 2 is a sectional elevation taken on the line y y of Fig. 1.
Similar letters of reference indicate corresponding parts.
A is the drum-shaft, and B the ratchet-dis thereon. Said disk is provided with an annular groove, 0, on each side, near the periphery.
D represents the yoke or frame, embracing said disk on both sides, and having a section of an annular flange, E, projecting into said groove. F is a socketed head on said yoke, above the flanges radially, also above the periphery of the disk, in which the lever G is placed, either to project to one side of the drum, or both, for being worked at one or both ends. H is the pawl, which is pivoted to the yoke-head in the ordinary way, for acting on the periphery of the disks. This yoke or frame consists, mainly, of two curved bars, representin g about three-quarters of a circle, placed on the sides of the disk, and confined upon it by the head F, pins I, and the flanges; but it may be constructed in any approved Way.
The said yoke is practically a prolongation of the lever G, which might be attached to the head in a line radial to the axis of the drum; but I prefer to attach it'iu the manner shown, because'it can, as before stated, pass 7 through a socket in said head and project on each side of the drum,.for the application of power at both ends. y
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent The pawl-lever, attached to the ratchet-disk of a winch or Windlass by a yoke or frame, D, having a flange, E, working in an annular groove, 0, in each side of said disk, substantially in the manner described.
