page_text: WILLIAM HILLYARD N° 43 Walton Street, Teams Gateshead-on-Tyne Durham Co.
Engineers Foreman, do hereby declare the nature of my invention for AN
IMPROVED SHIPS WARPING OR OTHER CAPSTANS, USED FOR WINDLASSES OR
OTHERWISE; to be as follows:-
The invention described as above, and for which I claim Letters Patent, is an
invention for obtaining a single, and a double purchase motion to such warping or
other Capstans, or Capstan Windlasses, firstly, to such Capstan itself, Secondly, a
single and double purchase motion from the Capstan to a windlass, winch, or other
machine, thirdly a single and double purchase inotion from such Windlass, winch,
or other machine, to the said Capstan, all in such a manner as is hereafter described
by me, and as shewn on my drawings.
1st, I obtain a circular or single purchase motion to barrel. C. by turning head A,
(which carries Pawls B) right or left, pins E, and G being taken out.
2nd I put in pin G. and turn head A left or right, when I obtain a double
purchase motion to barrel C.
3rd I take out pin G and put in pawls K and clutch D, when by moving head A
right or left I obtain a double purchase motion to shaft S.
4th I put in pin E, when I obtain a circular or single purchase motion to
shaft S.
5th By turning shaft S. I obtain a single purchase motion to barrel C, arrange-
ment being as before.
6th I take out of gear clutch D, and put in pin G when by turning shaft S,
I have a double purchase motion to barrel C.
I therefore claim letters patent for the application of:
(a). Pawls marked B, or by pins, cotters, or any such device, for the same
purpose, viz: to cause barrel C to turn at the same speed as head A, or a different
speed, all as herein set forth.
(b) for my method of obtaining a double purchase motion to barrel C, by means
of spur pinions H or other kind of gearing being fixed to, or in connection with,
directly or indirectly to barrel C.
(c) for the principal of having wheel I convertible from a rotary wheel, to
a fixed trod wheel by means of its passing through base plate J and connected

page_text: with a clutch, pin or pawls as shewn or by other contrivance, to any part of
capstan.
(d.) for the several combinations of mechanism, and arrangements, all as shewn
herein, for the above named purpose of obtaining the several motions already set
forth, and for which I claim the following advantages:
1. The obtaining of a Capstan of great power for Warping or other purposes.
2. The obtaining of a capstan capable of producing a double purchase motion to
a ships windlass, or any other machine, in connection therewith, whereby a heavier
weight may be lifted or greater power exerted, than is obtained by an ordinary
capstan.
3. The obtaining of a capstan having a single and double purchase motion
upwards through vertical shaft, whether such shaft be moved by steam hand or
other means.
4. The obtaining of a capstan with six or any less number of motions, that is
self-contained all as shewn and substantially set forth herein.
Parts marked A. C. E. F. H. J. K. S. are arranged as shewn by ine for the several
purposes mentioned herein.
Part marked. L is a new application.
Parts marked B. G. D. I are new principles.

page_text: I, WILLIAM HILLYARD of 43 Walton Street Gateshead on Tyne Engineer do
hereby declare the nature of my invention for IMPROVEMENTS IN WARPING, AND
OTHER CAPSTANS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention described as above is for, and relates to working Capstans on land
or on the decks of Ships, also Capstan Windlasses, with double purchase gear
motions in addition to the usual single or circular motions.
These double purchase motions are imparted to the Capstan barrels or Capstan
Windlasses by means of Spur, bevel, or other gearing, made of any suitable
materiel.
This gearing is so arranged by my invention, that it also imparts a single and
double purchase motion to a central shaft. or spindle, round which a hollow shaft
or sleeve and the Capstan revolves, this central shaft carrying the Lifter for heaving
in a Ships Chain Cables, or can be connected by suitable gearing to a Ships Wind-
lass, or other inachine for the same or any other purpose.
This gearing also gives single and double purchase motions to the Capstan
barrels when the initial moving force is conveyed by or through the said central
shaft by steam or other power.
These several motions are by my invention obtained in the following manner,
namely:
A Capstan head, marked A in Fig. 1. of my drawings and which receives the
ordinary Capstan bars, or a wheel marked W in Fig. 5, to which motion is given
by a crank handle, are made to receive or be connected to, a sleeve marked S, this
sleeve passes over the central shaft, and through the Capstan barrels which are
marked B; at opposite end of sleeve is cast on, or fixed thereto a spur, bevel or
other pinion, which pinion works into one or more other pinions, or intermediate
wheels marked I. W. These intermediate wheels work into a larger spur, bevel or
other wheel marked L. W., which wheel acts as a trod wheel, being prevented
from moving round by pins, cotters or other contrivances passing into it, or by
being keyed to the central shaft, also it may be geared into a clutch sliding on a
key, as shewn in Fig. 1, or a similar device. When this said wheel is thus connected
to the shaft, it acts as a driving wheel to the shaft as seen in Fig. 1, or drives the
barrel as shewn in Fig. 2, the pins which prevented its turning being now with-
drawn. Therefore if I turn the sleeve. S. and hold the barrel B, Fig. 1 the large
wheel L W is driven round, but if I hold the large wheel, the barrel goes round, as
the pinions are treading the circumference of the wheel. When this wheel acts as
a trod wheel, the purchase is greater than when used as a driving wheel. I therefore
attach the spindles upon which the trod pinions revolve, to the object requiring
the greater power; as seen in my drawings, they are attached to barrel in Fig. 1,
also to drive the shaft in Fig. 2. and also to drive the lifter in Fig. 3. I groove the
wheel on its periphery, when I use it in a direct manner for lifting chains. (Fig. 4.)
For single purchase motions, I place in the head of Capstan, one or more pawls,
which engage into notches within the top of the Capstan barrel, or use the ordinary
driving pin shewn in Fig. 1.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is;
1. Letters patent for my principle of obtaining double purchase motions to
separate bodies or objects by using a Convertible wheel, such wheel being employed
one way as a rotary or driving wheel connected directly or indirectly to the objects
it is required to drive, and converted from a driving wheel into a trod wheel by
having pins, pawls, cotters or keys so arranged that they prevent it from moving
round.
2. For my method of obtaining double purchaso motions to separate bodies by
having the pinions which gear into the aforesaid wheel, convertible from trod
pinions to intermediate wheels, such pinions working upon spindles attached
directly or indirectly to one of the bodies requiring to be driven.
t
3. For the application of pawls, also sleeve for working the aforesaid wheel and
pinions, and the arrangements and combinations of mechanism stated herein, and
shewn on my drawings.
WILLIAM HILLYARD.
