CHRISTOPHER COATSWORTH JORDESON, OF MONTREAL, CANADA.
Letters Patent No. 112,148, daad February 28, 1871.
IMPROVEMENT IN SHIPS WINDLASSES.
The Schedule referred to in these Letters Patent and making part: of the lame.
the following is a full, clear, and exact description of' the construction and operation of the same, referencebeing had to annexed drawing, where- Figure I represents a front elevation of the wind lass.
Figure II represents a sectional elevation ou'line A B, Fig. I.
'lhis invention relates to that class of wiudlas'ses which isv provided with a vertical screw-shaft, en` gaging with a toothed horizontal shaft, the former being connected with the windlass proper, and the latter` being employed for holding the chain which` is wound upon it; and consists in certain details of construction, which shall be fully described hereinafter.
In the drawing hereunto annexed similar letters of reference indicate like parts.
Letter a is any ordinary or suitable framework, for holding the various parts of the machine'in theirl respective positions. y
b represents a capstan, which, in its general com struction, is of ordinary form.
It is, however, provided with a central opening, which incloses the shaft c, upon which latter it revolves freely in either direction.
4To check its movement at any desired position pawls, k, are provided, the lower ends of which engage with a circulartoothed plate.
Upon the top of shaft c is also located acircular disk, provided with proper handspike-holes, which disk is rigidly attached to shaft c.
lhe latter extends downward beneath the disk upon which `the capstan rests, and on its lower part a screw, d, is formed, as shown inthe drawing.
Although a three-threaded screw is therein delineated, I do not contine `myselfI to any particular pitch or any number of threads, it being sutlicient to state that they will be in proportion to the amount of leverage required.
I would also remark that the thread of the screw shown in the drawing is that known by the name of a box-screw, but, if preferred, a V-screw may be used.
rlhe shaft c is situated a suitable distance from the barrel of the windlass e, for the thread of the screw d to intel-mesh with the teeth f of the wheel g, properly coniigurated for that purpose; and, if desired, o're than one tooth of the wheel g may be in gear with the thread or threads of the screw d.
The apparatus above described is provided with thel ordinary pawl or resistance-posts h, and set of pawls biting into suitable toothed wheels i i for that purpose.
. `It is evident that the power of this machine may be increased to almost an unlimited extent by diminishing the pitch of the thread on the shaft c, and increasing the diameter or the number of teeth f on the lwheel y, or by repeating the invention, in the same manner, as a compound lever, to give additional power.
The windlass b is also provided with the ordinary pawls k and with any suitable openings, l, for the reception of a corresponding number of handspikes, n, by which it is operated. i
YItwill be observed `that the capstan b Acan be revolved independently of the shaft c.
This capstan is designed for light work, while the other portions of the devices described are designed for heavier work. They can, of course, be used independently of each other.
I do not claim a windlass provided with a vertical screw-shaft which engages with a, horizontal toothed shaft; but,
Having thus fully described my invention,
What I claim as new, and desire to secure by Let ters Patent, is
The combination of the capstan b, constructed as described, with the shaft c, havingthe screw d, when operating as described, for the purpose set forth.
Montreal, 21st day of September, A. D. 1870.
