PROVISIONAL SPECIFICATION.
Improvements in the Machinery for Actuating Winches.
I, DUNDAS WILLIAM PORTEOUS, of 55 Back Sneddon Street, Paisley, in the County
of Renfrew, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements upon an invention for which Letters Patent
were granted to me, and which is described in the Specification, dated 3d June, 1885,
and numbered 6726; and has for its object to improve the construction of the
Machinery for actuating Winches, of a similar character to that described in said
Specification, so as to render them more suitable in their application to special
purposes, such as when employed as Steering Gears-For this purpose (1st) I
substitute, in place of either the first or second modification of valve gear described in
aforesaid Specification, the following arrangement of valve gear viz.:-I employ an
eccentric or eccentrics having an elongated hole or slot passing through, fitted on two
sides of a square formed on second part of main shaft, described in aforesaid Specifica-
tion, so that it or they can be made to slide across the said second part of main shaft,
in such a manner as to take up the proper relative position to the crank pin of Engine
or Engines, described in aforesaid Specification, for turning in either direction as
required To accomplish this, I have on said second part of main shaft, a bevel wheel,
loose but connected to a spur pinion also loose, gearing into a wheel either keyed or
fitted on a feather or feathers on the secondary shaft described in aforesaid Specifica-
tion This bevel wheel gears into another bevel wheel fitted on a suitable screw held
at right angles to, and so that it is carried round with, said second part of main shaft,
by suitable means-This screw is fitted into a nut, connected with said eccentric or
eccentrics, and is provided with two stops, to prevent said nut from travelling too far
and jamming By this means, on turning the said secondary shaft, the said eccentric
or eccentrics, is or are moved across said second part of main shaft, and the said
Engine or Engines may be started or reversed at pleasure-When the said secondary
DQ77

page_text: shaft is stopped, the said Engine or Engines, moving in relation to the position of
said eccentric or eccentrics, causes or cause said screw to turn in the direction opposite
to that imparted to it, by the rotation of said secondary shaft, and by so doing moves
or move the said eccentric or eccentrics across the said second part of main shaft, so
that the valve or valves regulating the admission of steam or other fluid to the said
Engine or Engines, is or are quickly made to close the ports. Thus the said Engine
or Engines is or are completely under control of the person manipulating said
secondary shaft.
(2nd) In place of either the third or fourth modification of valve gear described in
aforesaid Specification, I substitute an arrangement of eccentric or eccentrics with
elongated hole passing through, fitted on two sides of a square formed on a sleeve on
a stud or on another shaft, supported by one or both of the standards described in
aforesaid Specification; so that said eccentric or eccentrics can be made to slide
across said sleeve on stud, or said other shaft; by means of pinion communicating
with said secondary shaft, two bevel wheels, screw and nut. connected to said eccentric
or eccentrics as in arrangement (1) above-Said sleeve on stud, or said other shaft,
being connected with said second part of main shaft, either by toothed, grooved or
chain wheels and chain-All in such a manner that on turning said secondary shaft,
the Engine or Engines aforesaid may be started or reversed at pleasure-(3d) Another
means for sliding said eccentric or eccentrics across said second part of main shaft, or
across said sleeve on stud or said other shaft, described in arrangements (1 and 2)
above, may be substituted in place of the said bevel wheels, said screw, and said nut
connected to said eccentric or eccentrics, in these two arrangements, and consists of
the following viz.:-a disc or plate having a slot in the form of a volute scroll formed
in it; into this slot is fitted a projecting pin or lug attached to said eccentric or
eccentrics-This disc or plate is loose on said second part of main shaft, in arrange-
ment (1); or loose on said sleeve on stud or said other shaft, in arrangement (2) ;
but connected with said loose spur pinion which gears into said wheel on said
secondary shaft-Thus on turning said secondary shaft, said disc with volute scroll is
also turned and causes the said eccentric or eccentrics to slide across, in such a manner
as to open the said valve or valves admitting steam or other fluid to said Engine or
Engines, and said Engine or Engines may be started or reversed at pleasure-On
stopping said secondary shaft, the said disc with volute scroll will also stop and the
said Engine or Engines will continue to move in relation to position of said eccentric
or eccentrics, until said projecting pin or lug attached to said eccentric or eccentrics,
arrive at a point of the volute scroll when said valve or valves of said Engine or
Engines will close the ports-Should it be desirable for the said Engine or Engines
to close the ports slowly, a differential combination of wheels may be employed to
connect said disc or plate having volute scroll with said loose spur pinion, gearing into
said wheel on said secondary shaft.
(4th) In cases when the steam or other fluid is under high pressure, I employ a
cut off arrangement, which consists of the following viz. :-In suitable relative position
to the said second part of main shaft, I have a shaft, which I shall call the cut off
shaft, supported in suitable bearings, and free to travel a certain distance in the
direction of its axis, whilst revolving--On this cut off shaft, I have a toothed wheel
keyed, gearing into the said spur pinion loose on said second part of main shaft,
which gears into said wheel on said secondary shaft. This said cut off shaft has a
screw thread formed on it, which fits into a nut, free to revolve, but prevented from
moving in the direction of the axis of said cut off shaft, by suitable means-This nut
is connected to a toothed or friction wheel carried loosely on said cut off shaft, and
gearing into another toothed or friction wheel fastened on said second part of main
shaft. Attached to the standard of Winch, described in aforesaid Specification as
having the passages for steam or other fluid, cast in or attached to it, I have a suitable
valve chamber with a port connected with said passages, and having another opening
for the supply; in this chamber a suitable valve slides, which may be either flat or of
the piston type-The spindle. of this valve is connected with said cut off shaft-By
means of this arrangement, on turning the said secondary shaft, the said cut off shaft

page_text: is made to turn simultaneously, and in doing so to advance in the direction of its axis,
and at the same time move the said slide valve across its port so as to open it for the
ingress of steam or other fluid to the passages leading to said Engine or Engines―
On stopping said secondary shaft, the said Engine or Engines will continue to move
the said second part of main shaft, which being geared with said wheel connected to
said nut on screw thread on said cut off shaft, causes said cut off shaft to move along
its axis in the opposite direction to that in which it was made to advance by turning
said secondary shaft, and it being connected to said slide valve, causes it to move so
as to close its port, and thus cut off the supply of steam or other fluid from said
Engine or Engines.
Dated this First day of November 1886.

page_text: I, DUNDAS WILLIAM PORTEOUS, of 55 Back Sneddon Street, Paisley, in the county
of Renfrew, 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 improvements upon an invention for which Letters Patent
were granted to me, and which is described in the Specification dated 3d June 1885
and numbered 6726; and has for its object to improve the construction of the
machinery for actuating Winches, of a similar character to that described in said
Specification, so as to render them more suitable in their application to special
purposes, such as when employed as Steering Gears.
For this purpose (1) I substitute in place of either the first or second modification
of Valve Gear described in aforesaid Specification, the following arrangement of valve
gear-viz-I employ an eccentric or eccentrics having an elongated hole or slot
passing through, fitted on two sides of a square formed on the second part of main
shaft described in aforesaid Specification, so that it or they can be made to slide across
the said second part of main shaft, in such a manner as to take up the proper relative
position to the crank pin of Engine or Engines described in aforesaid Specification,
for turning in either direction as required.
To accomplish this, I have on said second part of main shaft a bevel wheel loose,
but connected to a spur pinion also loose, gearing into a wheel either keyed or fitted
on a feather or feathers on the secondary shaft described in aforesaid specification-
This bevel wheel gears into another bevel wheel fitted on a suitable screw held at right
angles to and so that it is carried round with said second part of main shaft by suitable
means. This screw is fitted into a nut connected with said eccentric or eccentrics,
and is provided with two stops to prevent said nut from travelling too far and
jamming By this means, on turning the said secondary shaft, the said eccentric or
eccentrics is or are moved across said second part of main shaft, and the said Engine
or Engines may be started or reversed at pleasure-When the said secondary shaft is
stopped, the said Engine or Engines moving in relation to the position of said eccentric
or eccentric causes or cause said screw to turn in the direction opposite to that
imparted to it by the rotation of said secondary shaft, and by so doing moves or move

page_text: the said eccentric or eccentrics across the said second part of main shaft, so that the
valve or valves regulating the admission of steam or other fluid to the said Engine or
Engines is or are quickly made to close the ports. Thus the said Engine or Engines
is or are completely under control of the person manipulating said secondary shaft.
(2) In place of either the third or fourth modification of valve gear described in
aforesaid Specification, I substitute an arrangement of eccentric or eccentrics with
elongated hole passing through, fitted on two sides of a square formed on a sleeve on a
stud, or on another shaft supported by one or both of the standards described in
aforesaid Specification; so that said eccentric or eccentrics can be made to slide
across said sleeve on stud or said other shaft, by means of pinion communicating with
said secondary shaft, two bevel wheels, screw and nut connected to said eccentric or
eccentrics as in arrangement (1) above said sleeve on stud or said other shaft being
connected with said second part of main shaft, either by toothed, grooved, or chain
wheels and chain; all in such a manner that on turning said secondary shaft, the
Engine or Engines aforesaid may be started or reversed at pleasure.
(3) Another means for sliding said eccentric or eccentrics across said second part
of main shaft, or across said sleeve on stud or said other shaft, described in arrange-
ments (1) and (2) above, may be substituted in place of the bevel wheels, said screw
and said nut connected to said eccentric or eccentrics in these two arrangements,
and consists of the following, viz. a disc or plate having a slot in the form of a
volute scroll formed in it-Into this slot is fitted a projecting pin or lug attached
to said eccentric or eccentrics. This disc or plate is loose on said second part of
main shaft, in arrangement (1), or loose on said sleeve on stud or said other shaft
in arrangement (2), but connected with said loose spur pinion which gears into
said wheel on said secondary shaft. Thus on turning said secondary shaft, said disc
with volute scroll is also turned and causes the said eccentric or eccentrics to slide
across in such a manner as to open the said valve or valves admitting steam or other
fluid to said Engine or Engines; and said Engine or Engines may be started or
reversed at pleasure-On stopping said secondary shaft, the said disc with volute scroll
will also stop, and the said Engine or Engines will continue to move in relation to
the position of said eccentric or eccentrics, until said projecting pin or lug, attached
to said eccentric or eccentrics, arrives at a point of the volute scroll when said valve
or valves of said Engine or Engines will close the ports-Should it be desirable for
the said Engine or Engines to close the ports slowly, a differential combination of
wheels may be employed to connect said disc or plate having volute scroll with said
loose spur pinion gearing into said wheel on said secondary shaft.
(4) In cases when the steam or other fluid is under high pressure I employ a cut off
arrangement, which consists of the following:-In suitable relative position to the
said second part of main shaft, I have a shaft (which I shall call the cut off shaft)
supported in suitable bearings, and free to travel a certain distance in the direction of
its axis whilst revolving. On this cut off shaft, I have a toothed wheel keyed, gearing
into the said spur pinion loose on said second part of main shaft, which gears into
said wheel on said secondary shaft. This said cut off shaft has a screw thread formed
on it, which fits into a nut free to revolve, but prevented from moving in the direction
of the axis of said cut off shaft, by suitable means. This nut is connected to a toothed
or friction wheel carried loosely on said cut off shaft, and gearing into another toothed
or friction wheel fastened on said second part of main shaft. Attached to the standard
of Winch, described in aforesaid specification, as having the passages for steam or
other fluid cast in or attached to it, I have a suitable valve chamber with a port
connected with said passages and having another opening for the supply; in this
chamber a suitable valve slides, which may be either flat or of the piston type-The
spindle of this valve is connected with said cut off shaft-By means of this arrange-
ment, on turning the said secondary sbaft, the said cut off shaft is made to turn
simultaneously, and in doing so to advance in the direction of its axis, and at the
same time move the said slide valve across its port so as to open it for the ingress of
steam or other fluid to the passages leading to said Engine or Engines-On stopping
said secondary shaft, the said Engine or Engines will continue to move the said

page_text: second part of main shaft, which being geared with said wheel connected with said nut
on screw thread on said cut off shaft, causes said cut off shaft to move along its axis
in the opposite direction to that in which it was made to advance by turning said
secondary shaft, and it being connected to said slide valve causes it to move so as to
close its port and thus cut off the supply of steam or other fluid from said Engine or
Engines.
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 two sheets of drawings hereunto appended,
that is to say In the drawings similar parts are referred to by the same numbers-
Figures 1 and 2 illustrate the first mentioned improvement-Figures 3 and 4 shew
the second mentioned improvement-Figures 5 and 6 shew the third mentioned
improvement and Figures 7 and 8 represent the cut off arrangement described as
the fourth improvement.
(1) Figures 1 and 2 represent one arrangement of valve gear which may be
substituted in place of either the first or second modification of valve gear described
in aforesaid Specification. The eccentric or eccentrics 21 having elongated hole
passing through is or are fitted to slide on two sides of a square formed on part 11 of
main shaft 77 is a bevel wheel loose on part 11 of main shaft, but connected to the
spur pinion 22 also loose, and gearing into the wheel 27 either keyed or fitted on
feathers on the secondary shaft 26 described in aforesaid Specification-The bevel
wheel 77 gears into the other bevel wheel 78 fixed on the screw 79 held at right
angles to and carried round with the part 11 of main shaft. The screw 79 is fitted
into the nut 80 connected to the eccentric or eccentrics 21; 81 and 82 are stops which
come into contact and prevent the nut 80 from travelling too far in either direction
and jamming By means of this arrangement, on turning the said secondary shaft. 26,
the said eccentric or eccentrics 21 is or are moved across said part 11 of main shaft in
such a manner that the Engine or Engines described in aforesaid Specification may be
started or reversed at pleasure. When the said secondary shaft 26 is stopped, the
said Engine or Engines moving in relation to the position of said eccentric or
eccentrics 21, causes or cause said screw 79 to turn in the direction opposite to that in
which it turned by the rotation of said secondary shaft 26, and by so doing moves or
move the said eccentric or eccentrics 21 across the said part 11 of main shaft, so that
the valve or valves regulating the admission of steam or other fluid to the said Engine
or Engines is or are made to close the ports. Thus the said Engine or Engines is or
are completely under control of the person manipulating said secondary shaft 26.
(2) Figures 3 and 4 illustrate a modification of valve gear which may be substituted
in place of either the third or fourth modification of valve gear described in aforesaid
Specification, and consists of the eccentric or eccentrics 21 with elongated hole passing
through, fitted to slide on two sides of a square formed on a sleeve on a stud or on
another shaft 64 supported by one or both of the standards described in aforesaid
Specification, so that said eccentric or eccentrics 21 can be made to slide across said
sleeve on stud or said other shaft 64, by means of the pinion 22 communicating with
the wheel 27 on said secondary shaft 26, the two bevel wheels 77 and 78, and the
screw 79, and the nut 80 connected to said eccentric or eccentrics 21 as in arrange-
ment (1) above-Said sleeve on stud or said other shaft 64 being connected with said
part 11 of main shaft by means of the wheel 62 attached to it communicating with the
other wheel 63 fixed on part 11 of main shaft. All in such a manner that on turning
said secondary shaft 26, the Engine or Engines aforesaid may be started or reversed
at pleasure-In the foregoing modification of valve gear the connecting wheels 62
and 63 may be either toothed, grooved or chain wheels as is found most convenient-
If chain wheels be used pitch chain will be required to make the communication
between the wheels complete.
(3) Figures 5 and 6 shew another means for sliding said eccentric or eccentrics 21
across said part 11 of main shaft or across said sleeve on stud or said other shaft 64
described in arrangements (1) and (2) above, which may be substituted in place of
the bevel wheels 77 and 78, the screw 79, and nut 80 connected to said eccentric or

page_text: eccentrics 21 in these two arrangements-This consists of the disc or plate 83 having
a slot in the form of a volute scroll formed in it-Into this slot is fitted a projecting
pin or lug 84 attached to said eccentric or eccentrics 21-The disc or plate 83 is
loose on the said part 11 of main shaft in arrangement (1); or loose on said sleeve on
stud or said other shaft 64 in arrangement (2), but connected with said loose spur
pinion 22, which gears into said wheel 27 on said secondary shaft 26. Thus on
turning said secondary shaft 26, the dise 83 with volute scroll is also turned and
causes the said eccentric or eccentrics 21 to slide across in such a manner as to open
the said valve or valves admitting steam or other fluid to said Engine or Engines, and
said Engine or Engines may be started or reversed at pleasure. On stopping said
secondary shaft 26, the disc 83 will also stop and the said Engine or Engines will
continue to move in relation to the position of sail eccentric or eccentrics 21 until said
projecting pin or lug 84 attached to said eccentric or eccentrics 21 arrives at a point
of the volute scroll when said valve or valves of said Engine or Engines will close
the ports.
(4) Figures 7 and 8 represent one form of cut off arrangement which I employ
when the actuating fluid is under high pressure; it consists of the cut off shaft 85
which is free to travel a certain distance in the direction of its axis whilst revolving-
86 is a toothed wheel keyed on the shaft 85, gearing into the said spur pinion 22 loose
on part 11 of main shaft, which gears into said wheel 27 on said secondary shaft 26.
The cut off shaft 85 has a screw thread formed on it which fits into the nut 87 free to
revolve but prevented from moving in the direction of the axis of the said cut off
shaft 85 by the bearing 88 in the standard 18 of the Winch-The nut 87 is connected
to the toothed wheel 89 free to revolve on said cut off shaft 85 and gearing into
another toothed wheel 90 fastened on said part 11 of main shaft-Attached to the
standard 18 of Winch described in aforesaid Specification as having the passages, for
steam or other fluid, cast in or attached to it, there is the valve chamber 91 having the
port 92 connected with said passages, and having the opening 93 for the supply-In
the chamber 91 the valve 94 slides, of which the spindle 95 is connected to the cut off
shaft 85 by the arm 96-By means of this arrangement, on turning the said secondary
shaft 26, the said cut off shaft 85 is made to turn simultaneously and in doing so to
advance in the direction of its axis, and at the same time move the slide valve 94
across its port 92 so as to open it for the ingress of steam or other fluid to the passages
leading to said Engine or Engines. On stopping said secondary shaft 26, the said
Engine or Engines will continue to move the said part 11 of main shaft, which being
geared with the wheel 89 connected to the nut 87 on screw thread on cut off shaft 85
causes said cut off shaft 85 to move along its axis in the opposite direction to that in
which it was made to advance by turning said secondary shaft 26, and it being
connected to the slide valve 94 causes it to move so as to close the port 92 and thus
cut off the supply of steam or other fluid from said Engine or Engines.
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 claim is :-
1st. In Winches, I claim the application of either modification of the combination
of eccentric or eccentrics with elongated hole passing through, fitted on two sides of
a square formed either on main shaft, or on a sleeve on a stud or other shaft, supported
by one or both standards of Winch, moved across said main shaft, sleeve on stud
or said other shaft, by means of loose pinion connected to bevel wheel gearing into.
another bevel wheel fixed on a screw held at right angles to and carried round with
said main shaft, sleeve on stud or said other shaft, said screw fitting into a nut
connected with said eccentric or eccentrics-Substantially as hereinbefore described
with reference to the accompanying drawings.
2nd. In Winches, I claim the application of either modification of the combination
of eccentric or eccentrics with elongated hole passing through, fitted on two sides of
a square formed either on main shaft, or on a sleeve on a stud or other shaft,
supported by one or both standards of Winch, moved across said main shaft, sleeve
on stud or said other shaft, by means of loose pinion connected to a disc or plate

page_text: having a volute scroll formed in it, into which is fitted a projecting pin or lug
attached to said eccentric or eccentrics-Substantially as described hereinbefore with
reference to the drawings hereunto appended.
3rd. In Winches, I claim the application of a cut off arrangement, by means of
which the supply of steam or other Huid may be cut off from the Engine or Engines,
automatically, on the person manipulating the Winch stopping the rotation of a shaft
by which the working of the Winch is controlled-Substantially as hereinbefore
described and illustrated in the accompanying drawings or any modification thereof..
Dated this Thirtieth day of July 1887.
