Improvements in or connected with Winches specially applicable for
Steam Trawlers or the like.
We, WILLIAM ROBINSON, of 28, Boynton Street, North Boulevard, Engineer,
and JAMES LEYMAN, of 225, North Boulevard, Fish Merchant, both in Hull, in the
County of Yorkshire, do hereby declare the nature of this invention to be as
follows:-
Our invention has reference to winches generally used on steam trawlers or the
like vessels for working the trawl gear, but applicable to winches, used for other
purposes, and has for its object, the obtaining of an easier or straighter lead from
the gallows or guides which lead the warp from the trawl boards or the like to
such winch, thus dispensing with certain of the fair lead rollers or bollards necessary
to the proper working of such gear with the existing construction of winch; and
by obtaining a straight lead it considerably reduces the wear and tear on the trawl
warp, as well as the wear and tear on the winch itself, thus reducing the amount
of power required by such winch for working the said trawl gear, thereby effecting
a saving in the quantity of fuel required for the driving of such winch.
For the purpose of our invention, in place of placing the barrels in the centre
of the winch as heretofore, we fit them at the sides, one at either side, preferably
outside the ordinary frame, and we may employ an extra standard at either side
to support them, the shaft may be carried through, and such barrels may be loose
on the said shaft and made to turn with the shaft by means of clutches, each
barrel having its own clutch, by this means the said barrels may turn independent
of each other and be worked one at a time or both together as required, or if desired,
the shaft, may be in two parts, divided preferably at the centre, the division been
within the large driving wheel, which would therefore preferably be loose on the
divided shaft, in this case the barrels would preferably be keyed or otherwise fixed
to the shaft.
The said driving wheel might work in two separate frames and be provided
with a square hole through it to take a squared part of the shaft, the wheel
turning loosely in two round bearings independent of the shaft, and the clutch
being with the wheel, when the clutch connects the two halves of such shaft, the
driving wheel by means of the square hole and squared part of such shaft drives
the barrels either both together or singly as required.
If desired the driving wheel may be keyed on to a loose tube on the shaft the
tube being clutched to the said shaft instead of the wheel.

We, WILLIAM ROBINSON, of 28, Boynton Street, North Boulevarde, Engineer,
and JAMES LEYMAN, of 225, North Boulevarde, Fish Merchant, both in Hull, in the
County of York, 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:-
Our invention has reference to winches generally employed for working the trawl
gear on steam trawlers or the like vessels, but is also applicable to winches used for
other purposes.
The object is to facilitate repairs or renewals of parts of the winch when at sea,
and to obtain an easier or straighter lead from the gallows or guides which lead
the warp from the trawl boards or the like to such winch, thus dispensing with
certain of the fairlead rollers or bollards necessary to the proper working of such
gear in the existing construction of winch. By obtaining a straight lead we con-
siderably reduce the wear and tear on both the trawl warp and the winch itself,
thus reducing the amount of power required to operate the winch and effecting a
saving of fuel.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of our improved winch.
Fig. 2 is a plan of same, in section.
Fig. 3 is an enlarged view of part of Fig. 2, showing the mechanism employed
for connecting or disconnecting the driving wheel and the warp barrels.
Fig. 4 is a detached view of part of Fig. 3, showing the driving wheel hub.
Fig. 5 is an end view of the central shaft bearing shown in Fig. 3.
For the purpose of our invention we mount the warp barrels A A one at each
side of the winch, instead of placing them in the centre as in the existing con-
struction of winch. The said barrels A. A, which are preferably made of wrought
iron in ring sections to facilitate renewals, are mounted preferably, outside the
ordinary frame, an additional standard B being employed at each side of the winch
to support them. The shaft C is carried through at each end to the said standard B,
the barrels A A being mounted loose on the said shaft C and being geared with the
said shaft when required by means of clutches D D of any suitable type, each
barrel having its own clutch. By this means the said barrels may be turned
independent of each other, and may be worked either separately or together as
required.
The shaft C is preferably made in two parts, the division being at the centre so
as to be within the main driving wheel E. The said main driving wheel E is
preferably keyed to a loose tube or hub F (see Figs. 3 and 4), which is mounted
in round bearings in the standards G G. The said hub F is made with a square
hole H, which is bored round at its centre K. Sliding clutches L L, operated by
levers M or the like, fit on the adjoining ends of the divided shaft C, and are so
arranged that when in their inner positions they gear with each other and so con-
neet the two parts of the said shaft, while at the same time they turn freely within
the round part K of the hub F. By this means the barrels A A may be worked
together so as to pay out the warp at both sides equally, without rotating any of
the geared wheels.
When the shaft is to be geared with the driving wheel E so as to pull in the
warps, the clutches L L are moved outwards, so as to engage with the square

page_text: parts H H of the hub F, and as the said clutches L L may be operated indepen-
dently, the warps may be drawn in at both sides equally or at one side only as
required.
When the said shaft C is in gear with the driving wheel E, either of or both the
barrels A A may be disconnected by means of the clutch or clutches D, without
disconnecting the shaft.
In lieu of employing the loose sleeve or hub F, the driving wheel E may if desired
be cast solid with the hub.
The pinion N, which transmits the motion from the crank shaft P to the driving
wheel E of the winch, being liable to excessive wear is preferably cast solid with
side flanges R which are bolted or otherwise secured to corresponding flanges on
the said crank shaft P. By this means the said pinion may be removed and
replaced when required without necessitating the removal of the entire crank
shaft P.
The barrels A. A, being made in sections, are also more easily repaired when
damaged by excessive strain either on the said barrels or on their brakes.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In a winch for controlling the trawl gear or steam trawlers or the like vessels,
the employment of warp barrels mounted at each side of the winch in suitable
standards outside the ordinary frame, substantially as, and for the purposes, shown
and described.
2. In a winch for controlling the trawl gear on steam trawlers or the like vessels
or for other similar purposes, the mechanism for throwing the warp barrels, or
either of them separately, into or out of gear with the driving wheel, so as to allow
the said barrels to be rotated in either direction either separately or together and
either in conjunction with or independent of the said driving wheel, substantially
as shown and described.
3. In a winch for controlling the trawl gear on steam trawlers or the like vessels,
the combination of the barrels A A, side standards B B, divided shaft C,
clutches D D, driving wheel E, fixed or loose hub F, standards GG, clutches L L.
and levers M M, all arranged and operated substantially as, and for the purposes,
shown and described.
