IMPROVEMENTS IN CAPSTAN APPARATUS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
"
We WILLIAM ELLIOTT of Ingate Ironworks, Beccles,. Suffolk and WILLIAM
GARROOD of Wheatacre, Norfolk, Engineers do. hereby declare the nature of the
said invention for "IMPROVEMENTS IN CAPSTAN APPARATUS to be as follows:
The primary object of this invention is to devise apparatus for use on fishing
boats, where the space available is very limited.; the apparatus can however be
used in other situations.
;
Generally the engines &c are placed below deck where they take up a great deal
of room, and necessitate the timbers being much cut away. Now by our invention
we avoid the drawbacks,
We employ a hollow shaft or spindle usually vertical upon which the capstan
revolves through this we bring our steam exhaust pipes and other connections with
the Engines. This hollow spindle is firmly secured to a base plate fixed to the deck
and above the capstan it carries the Engine bed plate and the Engines which are
disposed in any convenient manner and by suitable gearing connected with the
capstan. Differential gear can be used for speeding as required and Hand gear
may be arranged in readiness for use in case of a breakdown or lack of steam.
By the above arrangement a perfectly clear space is left all round the capstan
the machinery being kept out of the way of the ropes; the base plate also when so
arranged enables this apparatus to be readily substituted for other gears it being
only necessary to fit it down upon the deck in the place formerly occupied by the
old apparatus scribe the position of the deck holes, bore these and bolt down-the
plate.

page_text: We WILLIAM ELLIOTT, of Ingate Iron Works, Beccles, Suffolk and WILLIAM
GARROOD of Wheatacre Norfolk, Engineers, do hereby declare the nature of this
invention for "IMPROVEMENTS IN CAPSTAN APPARATUS" and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The primary object of this invention is to devise a capstan apparatus for use on
fishing boats, where the space available is very limited; the apparatus can however
be used in other situations.
Generally the Engines & are placed below deck where they take up a great deal
of room and necessitate the timbers being much cut away-Now by our invention
we avoid these drawbacks.
We employ a hollow shaft or spindle usually vertical upon which the capstan
revolves, and through this we bring our steam and exhaust pipes and other
connections with the Engines.
This hollow spindle is firmly secured to a base plate fixed to the Deck and, above
the capstan, it carries the Engine bed plate and the Engines which are disposed in
any convenient manner and by suitable gearing connected with the capstan.
Differential gear can be used for speeding as required" and Hand-gear may be
arranged in readiness for use in case of a break down or lack of steam.
By the above arrangement a perfectly clear space is left all round the capstan the
'machinery being kept out of the way of the ropes, the base plate also when so
arranged enables this apparatus to be readily substituted for other gears, it being
only necessary to fit it down upon the deck in the place formerly occupied by the
old apparatus, scribe the position of the deck holes, bore these and bolt down
the plate.
In the accompanying drawings, Figure." 1" is a sectional elevation of a capstan
apparatus according to our invention, Figure "2" is a like view of a modified form
of the same, Figures "3" and "4" represent two cross sections of the central pillar
and pipes.
It will be understood that the connection between the Engine and the capstan
'may be made in any convenient manner as that forms' no part of this invention
and the form or description of Engine and number of cylinders employed is
immaterial. Similarly the form or construction of the capstan does not specially
matter so long as it permits of the proper application of the Engines pipes &..
"A" is the Deck of the Boat and "B" the "pan" or baseplate "C" is the
Capstan and "D" the Engine resting (in Figure "1") upon the plate "E" on top
of the central tube "F" & above the capstan. "F" is the central tube inside which
the steam and exbaust pipes "G" and "H" are carried.
It will thus be seen that the central tube pipes and Engine are all fixed while
the capstan "C" is revolved round the central tube by means of the engine with
the intervention of any suitable gearing-The engines may be fitted with reversing
gear, or the reversing gear may be provided in the gearing or may be dispensed
with altogether.
<E
Figure "3" is a cross section of the central pillar and pipes of Figure "1" and
Figure 4" is a like view but in place of the hollow pillar a solid post is shewn
having longitudinal grooves or recesses, within which the pipes are laid and secured
by hoops or the like "I" as required.
In Figure "2" the Engine instead of being carried on top of the capstan is
placed inside it the pipes being carried up through the central opening as in

page_text: Figure "1"; the whole arrangement being such that the capstan revolves round
the Engine and pipes, which are thus entirely protected and out of the way of the
ropes &
In both cases nothing is exposed which might foul the ropes all round the
capstan.
Having now particularly described and ascertained the nature of the said
invention and what manner the same is to be performed we declare that what
we claim is-
1. In a capstan gear the combination with the capstan "C" of an Engine "D"
placed above it and supported upon the central tube or post "F" which carries the
pipe and other connections of the engine substantially as set forth and shewn in
Figure "1" of the accompanying drawings.
"
2. In a capstan gear the combination with the capstan C" of the central
tube or pillar "F" which carries the pipe and other connections of the engine
substantially as set forth.
3. In a capstan gear the method substantially as set forth of carrying the pipe
and connections of the Engine within the capstan.
4. In a capstan gear the combination with the capstan "C" of the Engine "D"
located inside the capstan substantially as set forth and shewn in Figure "2" of
the accompanying Drawings.
