page_text: I, WILLIAM CLARKE, of the Victoria Works, Gateshead-on-Tyne, in the County
of Durham, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to warping and anchor capstans. According thereto in
order that a capstan barrel may be readily removed and replaced the following
construction is adopted.
On the upper end of the capstan spindle is fixed a disc which is fitted with pawls
and may or may not have a groove for warping with steel wire rope. In or on the
upper face of this disc are several recesses to receive corresponding projections of the
lower part of the capstan barrel which is arranged above the disc.
The upper face of the disc is formed or provided with lugs or projections to
which are secured bolts that pass up through the head of the capstan barrel which
is thereby firmly secured to the disc the strain of withstanding the rotary pull of
the warp being borne by the projections engaging into the recesses as above
mentioned.
-
To remove the capstan barrel it is only necessary to remove the nuts from the
bolts when the barrel may be at once lifted off, or the holes through the capstan
head may be slotted, so as to allow the bolts to fall inwards when the nuts are
slightly eased back thus releasing the capstan barrel, and the replacement of the
capstan barrel may be performed in an equally expeditious manner.
An anchor capstan, whereby two cables, though greatly differing in size may be
worked either simultaneously or separately is according to this invention con-
structed as follows:-
On the capstan spindle are arranged two cable holders, namely one for the
larger cable, not keyed to but free to revolve upon the spindle, and another for the
smaller cable. This last mentioned cable holder is keyed to the spindle, and is
arranged above the holder for the larger cable.
A driving pin or pins is or are passed through the upper cable holder and into
the lower one so as to drive the latter when by manual or other power the spindle
is rotated. If the smaller cable alone is to be got in, the driving pin or pins is or
are not inserted and the upper cable holder alone is worked. It will be obvious
that if necessary the main and the stream cables can both be got in simultaneously.

page_text: Improvements in Warping and Anchor Capstans.
I, WILLIAM CLARKE, of the Victoria Works, Gateshead-on-Tyne, in the County
of Durham, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to warping and anchor capstans. According thereto in
order that a capstan barrel may be readily removed and replaced the following con-
struction is adopted. On the upper end of the capstan spindle is fixed a disc which
is fitted with pawls and may or may not have a groove for warping with steel
wire rope. In or on the upper face of this disc are several recesses to receive
corresponding projections of the lower part of the capstan barrel which is arranged
above the disc. The upper face of the disc is formed or provided with lugs or pro-
jections to which are secured bolts that pass up through the head of the capstan
barrel which is thereby firmly secured to the disc the strain of withstanding the
rotary pull of the warp being borne by the projections engaging into the recesses
as above mentioned. Referring to Sheet 1 of the accompanying drawings Fig. 1 is
a central vertical section of a capstan such as just above referred to and Fig. 2 is a

capstan barrel. B is the disc with recesses F to receive the projections F. of the
barrel and D is a spindle upon which the said disc is mounted. C is a base plate
with bearing for the spindle D and with the ratchet grooves or recesses for the
pawls G which are pivotted to the disc B. The capstan head is formed with holes
at A¹. E. E. are bolts jointed to lugs or projections A' formed with the disc B.
These bolts extend upward through the holes A¹ and are provided with nuts E¹.
To remove the capstan barrel it is only necessary to remove the nuts from the bolts
when the barrel may be at once lifted off, or the holes through the capstan head
may be slotted, so as to allow the bolts to fall inwards when the nuts are slightly
eased back thus releasing the capstan barrel, and the replacement of the capstan
barrel may be performed in an equally expeditious manner.
An anchor capstan, whereby two cables, though greatly differing in size may be
worked either simultaneously or separately is according to this invention con-
structed as follows:-
On the capstan spindle are arranged two cable holders, namely one for the
larger cable, not keyed to but free to revolve upon the spindle and another for the
smaller cable.
This last mentioned cable holder is keyed to the spindle and is arranged above
the holder for the larger cable.
A driving pin or pins is or are passed through the upper cable holder and into
the lower one so as to drive the latter when by manual or other power the spindle
is rotated. If the smaller cable alone is to be got in the driving pin or pins is or
are not inserted and the upper cable holder alone is worked. It will be obvious
that if necessary the main and the stream cables can both be got in simultaneously.
Referring to sheet 2 of the accompanying drawings, Fig. 1 is a central vertical
section of apparatus such as just referred to and Fig. 2 is a plan half in section

page_text: through the line A. B. and half in section through the line C. D. a is the capstan
spindle. b is the holder for the larger cable. It is not keyed upon the spindle but
is free to revolve thereon. c is the holder for the smaller cable. It is keyed to
the spindle and is arranged as shown above the holder b. The last mentioned
holder is provided with pawls d which engage with recesses or projections in a base
plate e so that backward rotation of the cable holder b is prevented. f is a driving
pin; there may be one or more. According to the plan view fig. 2 the apparatus
is arranged for three such driving pins. The driving pin f passes through the
upper cable holder c and into the lower one b so as to drive the latter as already
mentioned when by manual or other power the spindle a is rotated.
Having now particularly described and ascertained the nature of this inven▪
tion and in what manner the same is to be performed I declare that what
I claim is
1.) In a capstan, connecting the capstan barrel to a disc or bottom part substan-
tially in the manner hereinabove described with reference to sheet 1 of the
drawings so that the said barrel may be readily removed and replaced as above
set forth.
2.) The improved capstan shewn in and described with reference to sheet 1 of
the drawings.
3.) The combination with a capstan spindle of two cable holders one loose upon
the said spindle and the other keyed upon the same and a driving pin or pins
whereby the loose cable holder can be driven from the cable holder fixed upon the
spindle when desired substantially as described.
4.) The improved anchor capstan shewn in and described with reference to
sheet 2 of the drawings whereby two cables though greatly differing in size may
be worked either simultaneously or separately as above set forth.
