Improvements in or connected with Winches
We, JAMES BELL, of 38 Russian Dive, West Derby, in the County of
Lancaster, Ship Owner, WII LIAM CHARLES MI LVII LE, of 14 Coltart Road,
Liverpool, in the County of Lancaster, Engineer, and JAMES WILLIAM FOSTER,
of 56 Littledale Road, Seacombe, in the County of Chester, Salvage Agent, 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 has reference more particularly to winches for hauling in wie
1opes of large sizes, and where only one set of convolutions of 1ope on the winding
barrel or drum is permitted, e when the convolutions are not permitted to be
superposed one upon another on the bariel or diam, and where consequently
larger or smaller portion of the lifting on hauling rope is in the form of slack,
18 not being used or wound upon the baiel
2
In a winch for hauling wire ropes of large size, where only a certain length or
quantity of the rope used is ciriied on the hauling or winding dium, the remaining
poition or slack of the 10pc 18, under this invention, called on a dium, iecl, or
other device, which revolves at the same ite as the winding drum, the slack o
unused portion being passed direct from the winding dium or bel to the slack
crying barrel reel or device
In one form or construction of hauling winch on machinery under this invention,
and involving the above mode of carrying and dealing with the slach or unused
portion of the rope, the winding bariel (which is duiven by suitable geuing) is
carried in side frames, the part of the rope which is to be hauled upon and fixed
passes from the interior of the bach, through sime onto the exterior surface of
the barrel on which the slack or non-used portion is wound on a real or secondary
dium, which in one case, is mounted on the end of the barel, or a put connected
with it, and is operated by, or at the same rate of speed as the winding bariel
Within the winding barrel is tube or guide of gradual and suitable curvature
through which the rope is led from the winding bariel exterior to the slack storing
and cariying drum or reel, and there is also within the barrel suitable rope
gupping and holding device, by which the rope is firmly gripped and held
In the case where the reel or drum for carrying the slach is adapted to bu
disconnected from the winding barel, this part may serve, when the rope is not
being used, as a means of storing it, and upon it, the rope inay be shipped or sent
as and how desired
In one form of winch, applied with the improvements above referred to, for use
for raising very great weights or load, as for hauling large wire ropes, used in
lifting or iaising wrecks and where the ropes must not be superimposed one coil
upon another, the winding barrel is hollow, and works in suitable side frame
bearings and on one end of sime, outside the frame, the reel or winding device,
for stowing and carrying the lack or non-used portion of the rope, is ecured
The drum is, in some ca es, suitably driven by vertical worms, geating with worm
wheels on the drum at cach side, the shafts of these worms being supported in
stible "thrust-bearings at their lower ends, consisting of rings and thrust
blocks The shafts are rotated by other worm wheels therein with which geal
other worms, said worms being mounted on a common shaft The 1ope, in this

page_text: arrangement, would pass through the barrel, the gripping and holding device, and
onto the reel or drum for stowing and carrying the slack or non used portion of the
rope, in the manner above specified
The invention will be described with reference to the accompanying drawing>,
in which
Figure 1 is a side elevation, Figure 2 an end view, and Figure 3 a plan of the
winch
igure 4 is an internal view, shewing the interior barrel laid out flat
Figure 5 is a sectional elevation, and Figure 6 a plan in section at the line A A
Figure 5, shewing a modification of a part of the winch
By this invention, where only a certain length or quantity of the rope used is
carried on the hauling of winding dium, the remaining portion of the rope is carried
on a reel, drum, or like device, which revolves at the same rate as the winding
drum, the unused portion being passed direct from the winding drum or barrel, to
the reel on barrel carrying it
Refering to the drawing, the winch consists as follows -On the base of the
plate a, there are two lower frames b, one at either side, above which are two upper
half side frames 61, fitting on and bolted to b Supported by these is a hollow
winding barrel c, the ends c¹ of which work in the side frames, which form bearings
to the barel and on the end of this barel is a reel c² by which the unused portions
of the 1ope is carried The barrel c is worked by woim wheels d fixed on the
birrel e inside the fiames bb', norms e engaging with and driving them, these worms
being worked by worm wheels on the shifts el diven by worms g mounted on the
shaft g', said shift being rotated by a worm wheel thereon, driven by a worm
supported in one of the flauges and driven by the bevel wheels, from the shaft /,
this shaft being worked or revolved by suitable power
с
As regards the construction of the barrel c, and the angement of parts
connected with it, for storing and manipulating the 1ope o, at the stuiting of a
hauling on lifting action of the winch, the rope will be in the condition shewn ID
Figures 2 and 3, that is, lit le or none of it will be on the barrel, while the part of
it between the barrel c and the body to be moved would be furly tight, the
remainder of the 1ope being coiled on the winch or reel c
The mode of passing
this part of the rope to the reel c² 15 shewn more particularly in Figures 3 and 4
In the barrel at one side, there is a hole c³ of gradual curvature, so as not to bend
the rope at too great an angle in pa sing into the interior of the barrel ind in the
interior of the barrel, it is passed over grooved guides c of suitable curvature, ou
the interior of the barrel, to and fro, by which, when tension is put upon the rope,
fiction would be created, and some assistance to the holding of the rope afforded
Then introduced between the second guide c* and the reel 2, there is introduced
wne rope gripping device / of any known suitable kind, such as are commonly used
for gripping and holding wire ropes, by which the actual holding and making fist
of the rope is effected From this device, the rope is passed over the reel (² on
which it is not in tension, it being wound thereon merely to carry the unused
portion of the rope By the construction described, not only is the unused portion
carried, but also the lead of the rope from the exterior of the barrel to the reel is
nowhere bent or turned at such angle as to injure the rope, that is, the curves
which it takes are easy and gentle It will be seen, that in action, as the bauel
evolves, so the unused portion revolves with it
As regards the main geaning of the machine, each of the main worms e, which
drive the barrel, has its shaft vertically mounted, and the lower end of it
provided with rings e², which fit and work in corresponding grooves in the part L³
of the frames b By this construction, a suitable thi ust-block bearing is provided
which takes all the strain which comes upon the shafts e¹ and worms e
A modification of this method of supporting the shaft e¹ is illustrated m
Figures 5 and 6 and the improvement consists in the employment in connection
with the machine of hydraulic means for supporting the shaft e¹, and an indicating
means by which the pressure on the winch and the rope will be ascertained
This

page_text: consists essentially in cari ying the lower ends of the shafts e¹ on pistons supporte
on oil or other suitable liquid In the example given in the drawing, the collars e
of the shaft e¹, work in and are carried on a block p, made in halves and prevented
from rotating by a key g' on the retaining bracket and the lower end of the
shaft e¹ and block p rest upon a piston r working in a cylinder s in the bed plate a
of the winch In some cases, the cylinders are connected together
The shaft e¹
is mainly kept in position vertically by the cap v Only a small amount of move-
ment is allowed to the shaft e', and the amount of this is indicated by the space t
between the upper ring e² and the metal of the machine above it The adjustment,
vertically, of the shaft e' is effected by a screwed plug u which screws in and out
of the cylinder u¹ which is connected to the cylinder s by a passage u², and is filled
with oil, and accordingly as it is screwed in or out, so the piston r and the shaft e¹
are raised and lowered, respectively To indicate the pressure on the shaft and
piston, and so the lifting rope, a suitable pressure gauge will be used in connection
with the cylinders s or u¹
By this mode of adjusting, and also indicating, the pressure on the two shafts of
a winch, the pre sure on both sides of the winch can be regulated, and the strain
ascertained and besides this when several winches are used together for raising a
single body of great weight, as when raising a ship, the strain on the different
machines acting upon it can be seen at once, and controlled or regulated as
required
The gear introduced between the worms e and the motive power, whatever it
may be, may be varied according to circumstances, or as desired, and in no way is
it restricted to the particular geating shewn and described
It is to be stated in conclusion, that although the invention has been mainly
described with reference to the accompanying drawings in which a particular
construction and arrangements of parts of a winch are given (and which is a
convenient one, and may be used with advantage), yet it is not restricted to the
particular form or construction given in these drawings, since it can be modified or
varied in these respects, without departing from the chief characteristics of the
invention, and what is claimed as the several characteristics of the invention is
set out or referred to in the following claiming clauses
