I, DUNDAS WILLIAM PORTEOUS, of 55 Back Sneddon Street, Paisley, in the
county of Renfrew, Engineer, do hereby declare the nature of my invention for
"IMPROVEMENTS IN WINCHES, AND THE MACHINERY FOR ACTUATING THEM
to be as follows:-
>>
This invention relates to improvements upon an Invention for which Provisional
Protection was granted to me and which is described in the Provisional Specifi-
cation dated 9th September 1884, and numbered 12220, and has for its object the
simplifying and cheapening the construction of Winches, and the machinery
for actuating them, of a similar character to that described in said provisional
specification.
My invention consists, first of two standards so made as to be easily and
efficiently fastened to any, suitable foundation, which standards carry a certain
combination of wheels; one modification of which consists, first, of a circular
internally pitched rack or wheel, securely fastened to one of these standards;
secondly, of an internally pitched wheel, to which is connected the pulley or barrel,
which carries the chain or rope, and moving freely on the main shaft in suitable
bearings; thirdly of one or more externally pitched pinions, running loosely on an
eccentric fastened to the main shaft, (which may be hollow) working within the
internally pitched rack and wheel and gearing into them.
Another modification consists, first, of a circular internally pitched rack or
wheel securely fastened to one of the said standards; secondly, of an externally
pitched pinion, running. loosely on an eccentric fastened to the main shaft
(which may be hollow) working within the internally pitched rack or wheel,
and gearing into it, this pinion has two slots or projecting guides formed on
or fastened to one side of it, diametrically opposite; thirdly, of a' cross-piece
having four arms at right angles to one another, and a hole in the centre suffi-
ciently large to clear main shaft; two opposite arms of this piece fit into the
slots or guides on the said pinion, and the other two arins fit into two diametri-
cally opposite slots or guides formed in or fastened to one end of the pulley or
barrel, which carries the chain or rope and which moves freely on main shaft in
suitable bearings. Or instead of said cross-piece with four arms, fitting into the
slots or guides on pinion and pulley or barrel, a plate or disc, carrying four studs,
bolts or paps, correspondingly fitting into said slots or guides on pinion and pulley

page_text: or barrel, may be used-In the standard carrying the pitched rack, I have an
opening, through which the interior of the combination, can be inspected when
desired, said opening being closed by a moveable cover, carrying one end of main
shaft in suitable bearings-The main shaft is made in two seperate parts, the first
part of which carries the afore-said eccentric and pulley or barrel, and has a wheel
with part of a clutch formed on one side, fixed on one end of it; this wheel (which
may be either a toothed, grooved or chain-wheel) has a long pap formed on one
side, which passes through the boss of an intermediate bracket, and is thus
supported. On the other side of this wheel a recess is formed provided with a
bearing in which one end of the second part of the main shaft is supported; this
second part of the main shaft carries part of a clutch, on a feather or feathers,
which suits the part of clutch formed on said wheel, on end of the first part of
main shaft, and by means of this the two parts of main shaft can be connected
when desired-The second part of main shaft passes through a bearing in the
other standard, and has fixed at its outer end a crank or disc, preferably the latter,
to which I connect one or more Engines, preferably two, placed at any suitable
angle to each other, preferably ninety degrees, with piston rods provided with
guiding pieces which work in guides cast on or fastened to the extremes of one of
said standards, and connected to the crank or disc by return rods. The cylinder or
cylinders of said Engine or Engines is or are cast on or securely fixed to the standard
carrying said guides; this standard has suitable passages, either cast in or attached
to it, for ingress and egress of steam, or other fluid to and from the cylinder or
cylinders To actuate the valve or valves admitting steam or other fluid to the
cylinder or cylinders, I have one or more eccentrics to which is attached a pinion
or chain wheel, mounted loosely on a stud or shaft, supported by one or both of
said standards, or on a sleeve moving loosely on said stud or shaft. This eccentric
or eccentrics is or are connected with the valve or valves in the usual manner.
In suitable relative position to this eccentric or eccentrics, carried in bearings in
said standards, is a secondary shaft (which may be hollow) carrying loosely a
toothed, grooved or chain wheel, which communicates with the pinion or chain
wheel attached to the eccentric or eccentrics, and which may be fastened to or
disconnected from said secondary shaft at option by means of one side of a double
clutch By means of this arrangement the Engine or Engines can be started, or
reversed at pleasure, by operating said secondary shaft, and thus made to actuate
the pulley or barrel-If desirable to actuate the pulley or barrel, by hand at any
time, I have, on said secondary shaft, another toothed, grooved or chain wheel (which
can be fastened to, or disconnected from, it at option, by means of the other side of
said double clutch on secondary shaft) communicating with said toothed, grooved
or chain wheel on end of first part of main shaft.-By disconnecting the clutch on
second part of main shaft from the wheel on first part of main shaft, and connecting
the wheel communicating with it, on the said secondary shaft with its clutch;
I make the connection complete between the said secondary shaft (which may be
turned by hand) and the pulley or barrel independent of Engine or Engines-
Should it be desirable to have the machine actuated by hand power alone, the
wheel on secondary shaft communicating with wheel on first part of main shaft
may be a fixture-The said intermediate bracket with the pap of wheel on end of
first part of main shaft passing through its boss, serves to support the main shaft
at the junction of its two parts, and also to carry one end of pulley or barrel, and
thus relieve the main shaft from any undue strain-This intermediate bracket is
by means of two or more stay bolts passing through bosses on it, fastened securely
in its proper position, by nuts or other equivalent means to the said standards.
Said stay bolts also carry leading wheels to guide the chain or rope to the pulley
or barrel if desirable-Should it be wished to maintain, whilst revolving in either
direction, a fixed relative angular position between the eccentric or eccentrics, and
the crank pin of said Engine or Engines; I place a stop on the boss of either of the
said wheels on said secondary shaft, or on the said eccentric or eccentrics, or said
pinion or chain wheel attached thereto, which comes into contact with another stop

page_text: fixed in proper position on the said secondary shaft or other shaft or sleeve thereon,
or on sleeve on said stud-and I connect the shaft or sleeve having said stop fixed
on it, by means of toothed, grooved or chain wheels and chain, or other equivalent
means, with the second part of main shaft. The clutches on said secondary shaft
and second part of main shaft, are so arranged that by operating a hand wheel on
one end of a shaft, having a screw thread at the other end, which fits into a nut,
carried on one arm of a lever, the other arm of which is jointed to the end of
another lever, to which are connected two cods, fitted into grooves in the said
clutches, said clutches are actuated simultaneously, and in such a manner that,
when one clutch moves towards the right, the other moves towards the left.
Should it be requisite at any time to place the winch so far from its work, as to
be out of sight of it, I connect an indicator to the pulley or barrel, or any other
convenient working part, by any suitable means, and am thus enabled at any time
to notice the position of the load-I also connect a nut moving on a screw on said
secondary shaft, and having sufficient travel to allow the load to be manipulated
to any desired extent, when it will come into contact with a stop and prevent the
said secondary shaft from revolving any further in that direction.

"
Improvements in Winches and the Machinery for Actuating
them.
I, DUNDAS WILLIAM PORTEOUS, of 55 Back Sneddon Street, Paisley, in the
County of Renfrew, Engineer, do hereby declare the nature of my invention for
IMPROVEMENTS IN WINCHES, AND THE MACHINERY FOR ACTUATING THEM" 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 improvements upon an Invention for which Provisional
Protection was granted to me, and which is described in the Provisional Specifi-
cation dated 9th September, 1884, and numbered 12220; and has for its object
the simplifying and cheapening the construction of winches and the machinery
for actuating them of a similar character to that described in said Provisional
Specification.
My invention consists, first of two standards so made as to be easily and
efficiently fastened to any suitable foundation, which standards carry a certain
combination of wheels; one modification of which consists; first of a circular
internally pitched rack or wheel, securely fastened to one of these standards;
secondly, of an internally pitched wheel, to which is connected the pulley or barrel
which carries the chain or rope, and moving freely on the main shaft in suitable
bearings; thirdly, of one or more externally pitched pinions, running loosely on an
eccentric fastened to the main shaft, (which may be hollow) working within the
internally pitched rack and wheel, and gearing into them.
Another modification consists, first of a circular internally pitched rack or wheel
securely fastened to one of the said standards; secondly of an externally pitched
pinion running loosely on an eccentric fastened to the main shaft (which may be
hollow) working within the internally pitched rack or wheel and gearing into it,
this pinion has two slots or projecting guides formed on or fastened to one side of
it, diametrically opposite; thirdly of a cross-piece having four arms at right angles
to one another, and a hole in the centre sufficiently large to clear main shaft; two
opposite arms of this piece fit into the slots or guides on the said pinion and other
two arms fit into two diametrically opposite slots or guides formed on or fastened
to one end of the pulley or barrel, which carries the chain or rope and which moves
freely on main shaft in suitable bearings. Or, instead of said crosspiece with four
arms fitting into the slots or guides on pinion and pulley or barrel, a plate or disc
carrying four studs or bolts or paps, correspondingly fitting into said slots or guides
on pinion and pulley or barrel, may be used-In the standard carrying the pitched
rack, I have an opening through which the interior of the combination, can be
inspected when desired, said opening being closed by a moveable cover carrying
one end of main shaft in suitable bearings-The main shaft is made in two
seperate parts, the first part of which carries the aforesaid eccentric and pulley or
barrel, and has a wheel with part of a clutch formed on one side, fixed on one end
of it This wheel (which may be either a toothed, grooved or chain wheel) has a

page_text: pap formed on one side, which passes through the boss of an intermediate bracket
and is thus supported-On the other side of this wheel, a recess is formed,
provided with a bearing, in which one end of the second part of the main shaft is
supported this second part of the main shaft carries part of a clutch on a feather
or feathers, which suits the part of clutch formed on said wheel on end of the first
part of main shaft, and by means of this the two parts of main shaft can be
connected when desired-The second part of main shaft passes through a bearing
in the other standard, and has fixed at its outer end a crank or disc, preferably the
latter, to which I connect one or more engines, preferably two, placed at any
suitable angle to each other, preferably ninety degrees, with piston rods provided.
with guiding pieces which work in guides cast on or fastened to the extremes of
one of said standards, and connected to the crank or disc by return rods-The
cylinder or cylinders of said engine or engines is or are cast on or securely fixed to
the standard carrying said guides, this standard has suitable passages either cast
in or attached to it for ingress and egress of steam or other fluid to and from the
cylinder or cylinders-To actuate the valve or valves admitting steam or other
fluid to the cylinder or cylinders I have one or more eccentrics to which is attached
a pinion or chain wheel mounted loosely on a stud or shaft supported by one or
both of said standards, or on a sleeve moving loosely on said stud or shaft―This
eccentric or eccentrics is or are connected with the valve or valves in the usual
manuer In suitable relative position to this eccentric or eccentrics, carried in
bearings in said standards is a secondary shaft (which may be hollow) carrying
loosely a toothed, grooved or chain wheel, which communicates with the pinion or
chain wheel attached to the eccentric or eccentrics, and which may be fastened to
or disconnected from said secondary shaft at option, by means of one side of a
double clutch-By means of this arrangement the engine or engines can be started
or reversed at pleasure by operating said secondary shaft, and thus made to actuate
the pulley or barrel-If desirable to actuate the pulley or barrel by hand at any
time, I have on said secondary shaft, another wheel, either toothed, grooved or
chain, (which can be fastened to or disconnected from it at option, by means of the
other side of said double clutch on secondary shaft) communicating with said
toothed, grooved or chain wheel on end of first part of main shaft-By discon-
necting the clutch on second part of the main shaft, from the wheel on first part of
main shaft, and connecting the wheel communicating with it on the said secondary
shaft with its clutch, I make the connection complete between the said secondary
shaft (which may be turned by hand) and the pulley or barrel, independent of
engine or engines Should it be desirable to have the machine actuated by hand
power alone, the wheel on secondary shaft communicating with wheel on first part
of main shaft may be a fixture-The said intermediate bracket with the pap of
wheel on end of first part of main shaft passing through its boss, serves to support
the main shaft at the junction of its two parts-This intermediate bracket is by
means of two or more stay bolts passing through bosses on it, fastened securely in
its proper position, by nuts or other equivalent means to the said standards, said
stay bolts also carry leading wheels to guide the chain or rope to the pulley or
barrel, if desirable-Should it be wished to maintain, whilst revolving in either
direction, a fixed relative angular position between the eccentric or eccentrics, and
the crank pin of said engine or engines, I place a stop, on the boss of either of the
said wheels on said secondary shaft, or on the said eccentric or eccentrics, or said
pinion or chain wheel attached thereto, which comes into contact with another stop
fixed in proper position on the said secondary shaft, or other shaft, or sleeve
thereon, or on sleeve on said stud; and I connect the shaft or sleeve having said
stop fixed on it, by means of toothed, grooved or chain wheels and chain, or other
equivalent means with the second part of main shaft--The clutches on said
secondary shaft and second part of main shaft are so arranged, that by operating
a hand wheel on one end of a shaft, having a screw thread at the other end, which
fits into a nut, carried by one arm of a lever, the other arm of which is jointed to
the end of another lever to which are connected two cods fitted into grooves in the

page_text: said clutches; said clutches are actuated simultaneously and in such a manner that
when one clutch moves towards the right, the other moves towards the left.
Should it be requisite at any time to place the winch so far from its work as to
be out of sight of it, I connect an indicator to the pulley or barrel or any other
convenient working part, by any suitable means, and am thus enabled at any time
to notice the position of the load.
I also connect a nut, moving on a screw on said secondary shaft, and having
sufficient travel to allow the load to be manipulated to any desired extent, when it
will come into contact with a stop, and prevent the said secondary shaft from
revolving any further in that direction.
Having thus described the nature of my Invention I will proceed more
particularly to describe the manner in which the same is or may be performed or
carried out in practice-reference being made to the three sheets of drawings
hereto appended, that is to say-In the drawings similar parts are referred to by
the same numbers-Figures 1 and 2 are end elevations, the latter partly in section,
of a winch, illustrating what I believe to be the most convenient method (but not
the only method) of carrying my Invention into practical effect. Figure 3 is a
side elevation of same, partly in section, Figures 4 and 5, 6 and 7 are views of the
second modification of combination of wheels, with barrel. Figure 8 is a view of
intermediate bracket and wheels, with part of clutch arrangement. Figures 9
and 10, 11 and 12, and 13 and 14 illustrate different modifications of the gear for
actuating the valve or valves.
1 and 18 are standards which may be fastened to any suitable foundation, and
carrying the combination of wheels, which according to one modification consists,
first of the internally pitched rack or wheel 2 (Figures 1 and 3) formed on or
attached to the moveable cover 3, which is securely fastened by bolts or pins to
the standard 1; secondly, of the internally pitched wheel 4 to which is connected
the pulley 5 or barrel, which carries the chain or rope, and moving freely on the
main shaft in suitable bearings 6; thirdly of one or more externally pitched
pinions 7, running loosely on the eccentric 8, keyed or fastened to the part of the
main shaft 9. The pinion or pinions 7 work within the internally pitched rack 2
and wheel 4, and being carried round by the eccentric 8, gear into them. In the
standard 1 there is an opening through which, on removing the cover 3, the
interior of the combination of wheels 2 and 4, the pinion or pinions 7 and the
eccentric 8 may be inspected when desired, and when necessary lubricated. The
cover 3 has bearings 10 in which one end of the part 9 of main shaft is supported-
The main shaft is made in two seperate parts 9 and 11 (which may be hollow if
wished) of which the part 9 carries the aforesaid eccentric 8 and pulley 5 or barrel,
and has a wheel 12, with part of a clutch formed on one side, keyed or securely
fixed on one end of it-This wheel 12 (which may be either a toothed, grooved or
chain wheel) has a pap formed on one side, which passes through the boss 13 of an
intermediate bracket 14 and is thus supported-On the other side of the wheel 12
a recess is formed, provided with a bearing 15 in which one end of the part 11 of
main shaft is supported. The part 11 of main shaft carries part of a clutch 16 on a
feather or feathers, which suits the part of clutch formed on wheel 12 fixed on
end of part 9 of main shaft, and by means of this the two parts of main shaft 9
and 11, can be connected when desired-The part 11 of main shaft passes through
a bearing 17 in the second standard 18, and at its outer end, a crank or disc 19 is
fixed, to which the two engines 20, 20, are connected-As shewn the cylinders are
on outside and the valve casings on inside of standard 18. But I do not confine
myself to this arrangement, as the cylinders and casings may be placed both either
on outside or inside of standard 18, or, cylinders on inside and casings on outside,
which ever way may be most convenient-According to one modification of valve
gear (other modifications are hereinafter described) I have an eccentric 21 attached
to the pinion 22, and both loose on the part 11 of main shaft, and connected to
the valves of engines 20. 20; a stop 23 is attached to one side of eccentric 21-In
bearings 24 and 25 in the standards 1 and 18, is supported a secondary shaft 20

page_text: (which may be hollow) carrying loosely the wheel 27 (which may be either a
toothed, grooved or chain wheel) which communicates with the pinion 22. The
wheel 27 may be connected to or disconnected from the shaft 26 at option, by
means of one side of the double clutch 28, fitted on feathers on shaft 26-On the
part 11 of main shaft a stop 29 is fixed in proper position so that when the stop 23
on eccentric 21 is brought into contact with one end of stop 29 on part 11 of main
shaft; the valves, regulating the admission of steam or other fluid to the engines,
will be set properly for the revolution of the engines in corresponding direction-
And on bringing the stop 23 into contact with the other end of stop 29, the
direction of engines will be reversed.
Loose on the secondary shaft 26 there is another wheel 30, which may be
connected at option to shaft 26, by means of the other side of the double clutch 28;
the wheel 30 communicates with the wheel 12 on part 9 of main shaft-By
disconnecting the clutch 16 from the wheel 12, and connecting the wheel 30 with
its clutch 28, the connection is complete between the secondary shaft 26 (which
may be turned by hand in any suitable manner) and the pulley 5 or barrel
independent of engines 20, 20.
Should it be desirable to have the machine actuated by hand power alone, the
wheel 30 may be fixed on the shaft 26.
The intermediate bracket 14, with the pap of wheel 12 passing through its
boss 13, serves to support the two parts 9 and 11 of main shaft at their junction―
The bracket 14 is fastened securely in position by the stay bolts 31, 32 and 33,
passing through bosses on it to the standards 1 and 18-The stays 31, and 32,
carry leading wheels 34 and 35, to guide the chain or rope to the pulley 5 or
barrel The clutches 16 and 28 are so arranged that by operating the hand
wheel 36, on end of the shaft 37, having a screw thread at the other end
fitting into the nut 38, carried on one arm of the lever 39, the other arm of which
is jointed to the end of the lever 40, to which are connected cods fitted into
grooves in the clutches 16 and 28; the said clutches 16 and 28 are actuated
simultaneously, and in such a manner that when one clutch moves towards the
right, the other moves towards the left-An indicator 41, which shews the position
of the load, is connected with the pulley 5 or barrel, through the arm 42, taking
into a screw thread on the exterior of the internally pitched wheel 4, the vertical
spindle 43, the arm 44, the link 45 and the arm 46-On the shaft 26 a screw
thread is formed on which a nut 47 travels along the stay 50-48 and 49 are stop
nuts, which may be adjusted, so that on turning the shaft 26, when 47 comes into
contact with either, the shaft 26 is prevented from revolving any further in that
direction.
A second modification of combination of wheels, illustrated in Figures 4 and 5,
and 6 and 7, may be substituted in place of that modification hereinbefore
described, It consists first, of the circular internally pitched rack or wheel 2
formed on or attached to the moveable cover 3, which is securely fastened by bolts
or pins to the standard 1 (Figures 1 and 3); secondly, of an externally pitched
pinion 51, running loosely on the eccentric 8, fastened on the part of main shaft 9,
working within the internally pitched rack 2, and gearing into it; this pinion has
two slots or projecting guides 52, 52, formed on or fastened to one side of it,
diametrically opposite; thirdly, of a cross-piece 53, having four arms 54, 55, at
right angles to one another, and a hole in the centre sufficiently large to clear the
shaft 9; two opposite arms 54, 54, of this piece fit into the slots or guides 52, 52,
on the said pinion 51, and the other two arms 55, 55, fit into two diametrically
opposite slots or guides 56, 56, formed on or fastened to one end of the pulley or
barrel 5, which carries the chain or rope, and which moves freely on shaft 9. in
suitable bearings 6.
Or, instead of said cross-piece 53, a plate or disc 57, carrying four studs or bolts
or paps 58, correspondingly fitting into said slots or guides 52 and 56, on pinion 51
and pulley or barrel 5, respectively, may be used.

page_text: A second modification of the gear for actuating the valve or valves admitting
steam or other fluid, to the cylinder or cylinders of said engine or engines 20, is
represented by Figures 9 and 10, and may be substituted in place of the valve gear
herein before described; according to this modification, I have the eccentric or
eccentrics 21. with pinion 22 attached either by boss or sleeve, and all loose on
part 11 of main shaft; the wheel 27 on secondary shaft 26 and connected to it by
the clutch 28, has a stop 59 fixed or formed on it, a corresponding stop 60 is fixed
or formed on the sleeve 61, loose on shaft 26; attached to the sleeve 61 is a
wheel 62, which makes connection with another wheel 63, fixed on the part 11 of
main shaft.
By operating the shaft 26, the engine or engines aforesaid 20, may be started
or reversed at pleasure, and a fixed relative angular position is maintained, whilst
revolving in either direction, between the eccentric or eccentrics 21 and the crank
pin of said engine or engines 20.
A third modification of valve gear, represented by Figures 11 and 12, which
may be used if desirable, consists of the eccentric or eccentrics 21, with pinion 22
attached, either by boss or sleeve, loose on a stud 64 or shaft, supported by one or
both of aforesaid standards; carried loosely on said stud 64, or shaft, is a sleeve 65,
having a stop 66 fixed or formed on it, a corresponding stop 67 is attached to
either said pinion 22, or eccentric or eccentrics 21; attached to the sleeve 65 is a
connecting wheel 62, communicating with a corresponding connecting wheel 63,
fixed on part 11 of main shaft-Thus by operating secondary shaft 26, a fixed
relative angular position is maintained between the eccentric or eccentrics 21
and the crank pin of aforesaid engine or engines 20, whilst revolving in either
direction.
A fourth modification of valve gear, which may be substituted if convenient, is
shewn by Figures 13 and 14, and consists of the eccentric or eccentrics 21, the
pinion 22 and the connecting wheel 62, all attached, but loose on the stud 64 or
shaft, supported by one or both of aforesaid standards; the corresponding con-
necting wheel 63 is attached to a sleeve 68, loose on part 11 of main shaft, but
having a stop 69, fixed or formed on it, which, on operating secondary shaft 26,
comes into contact with the corresponding stop 70, fixed on part 11 of main shaft,
and thus maintains the proper relative angular position, between the eccentric or
eccentrics 21, and the crank pin of aforesaid engine or engines 20, whilst revolving
in either direction.
In any of the foregoing modifications of valve gear, the pinion 22 attached to
eccentric or eccentrics 21, and the wheel 27 on said secondary shaft 26, communi-
cating with said pinion 22; as also, the connecting wheels 62 and 63; may be
either toothed, grooved, or chain wheels, as is found most convenient-If chain
wheels are used, pitch chain will be required to make the communication between
the wheels complete.
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 clain is
1. The construction and arrangement of Winches and the machinery for actuating
them, as herein before described, and as illustrated in the accompanying drawings,
or any modification thereof.
2. In winches, I claim the application of either modification of combination of
externally and internally pitched wheels, in which an internally pitched rack or
wheel is securely fastened to one standard of winch, and so arranged that on
removing a moveable cover, the interior of the combination can be inspected,
through an opening in said standard; substantially as herein before described, with
reference to the drawings hereunto appended.
3. In winches, I claim the application of the various combinations of eccentric
or eccentrics on stud, or shaft, supported by one or both standards of winch, or on

page_text: sleeve thereon, with stop, on wheel on secondary shaft, or on said eccentric or
eccentrics, or pinion or chain wheel attached thereto, which comes into contact with
another stop fixed in proper position, on the said secondary shaft, or other shaft, or
sleeve thereon, or on sleeve on stud or shaft, supported by one or both standards
of winch; substantially as hereinbefore described, with reference to the drawings
hereunto appended.
4. In winches, I claim, in order to maintain a fixed relative angular position
between the eccentric or eccentrics, and the crank pin of engine or engines, the
connecting the shaft or sleeve having stop fixed on it, with the crank shaft, by
means of toothed, grooved or chain wheels and chain or other equivalent means;
substantially as set forth and described hereinbefore, in the various modifications,
with reference to the accompanying drawings.
5. In winches, I claim the arrangement of clutches substantially as hereinbefore
described, with reference to the accompanying drawings, and for the purposes set
forth.
6. In winches, I claim the supporting of one end of one part of main shaft, by
a bearing in a recess formed in a wheel, fixed on end of other part of main shaft;
substantially as herein before described with reference to the drawings hereunto
appended.
