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 bo
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 3rd June 1885,
and numbered 6726; and has for its objects, to simplify and improve the construction
of Winches and the Machinery for actuating them, of a similar character to that
described in said Specification, and to render their manipulation more easy, in their
application to general loads, or to special purposes, such as when employed as ash-
hoists or Steering Gears. For these purposes I construct the apparatus as follows:-
(1st.) I substitute in place of the wheels with double clutch, described in aforesaid
Specification, as carried by the secondary shaft, either one, or two toothed wheels
fastened together, fitted on a feather or feathers, to slide on said secondary shaft,
working alternately into corresponding pinions, one on first part of main shaft and
the other attached to an eccentric or eccentrics, according as desirable to work the
winch by hand or other power. By a simple combination of one clutch on second
part of main shaft, a double armed lever with two or more cods, and a small shaft
with crank or eccentric, or other equivalent means, actuated by a wheel or lever; the
aforesaid wheel or two wheels on said secondary, shaft, and said clutch on second part
of main shaft are so manipulated, that the transition from hand to other motive power,
and vice versa is readily made.
(2nd.) I make the pulley or barrel a seperate piece, but connected to the second
internally pitched wheel in first modification of combination of wheels described in
aforesaid Specification, either by bolts, pins, or projecting lugs fitting into corre-
sponding holes or recesses formed either on one end of pulley or barrel, or in web of
said internally pitched wheel; and so arranged, that on removing the cover, mentioned
in aforesaid Specification as closing the opening in Standard, the externally pitched
pinion or pinions, the second internally pitched wheel, and the eccentric, described in
first modification; or the externally pitched pinion, eccentric, and crosspiece or its

page_text: equivalent, described in second modification of combination of wheels; as also the
pulley or barrel may be taken out, through said opening when desirable, without
removing, or disturbing the fastening of, the standard carrying the combination of
wheels.
(3rd.) I attach to either part of main shaft, a friction wheel or roller (which may
he grooved or plain) working in contact with another friction wheel or roller attached
to secondary shaft; and thus constitute a connection between the engine or engines
and the eccentric or eccentrics, when desirable to allow the winch to work automatically
at any time The friction being so tempered, as to be able to overcome the inertia of
said secondary shaft, and at the same time to be easily brought to a state of rest by
slight frictional pressure on a hand wheel fastened to said secondary shaft.
(4th.) 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-
Fastened on said second part of main shaft is a plate or disc, having one or more slots
or guides (either straight. or curved) formed in or on it; on one side of the eccentric
or eccentrics which actuate the valve or valves of aforesaid engine or engines (and
which I shall call the main eccentric or eccentrics) are corresponding pins or guides
which fit and slide in or on said guides in or on said plate or disc-In said main
eccentric or eccentrics there is an elongated hole passing through, in which, or in
guides formed in or on the other side of main eccentric or eccentrics, a secondary
eccentric works. This secondary eccentric is attached to a pinion communicating
with a wheel on said secondary shaft described in aforesaid Specification; and so
arranged that on turning said secondary shaft, the main eccentric or eccentrics is or
are shifted across said second part of main shaft in such a manner that the engine or
engines described in aforesaid Specification may be started or reversed at pleasure.
5th.) In place of either the third or fourth modification of valve gear described in
aforesaid Specification, I substitute an arrangement of main eccentric or eccentrics
with elongated hole passing through, shifted by a secondary eccentric attached to a
pinion loose on a stud or other shaft supported by one or both of tho standards
described inaforesaid Specification, said pinion communicating with a wheel on aforesaid
secondary shaft, said main eccentric or eccentrics being guided along guides in or
on a plate or disc fastened on said other shaft, or on a sleeve loose on said other shaft
or stud, and said plate or disc 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.

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 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 3rd June 1885,
and numbered 6726; and has for its objects to simplify and improve the construction
of Winches and the Machinery for actuating them, of a similar character to that
described in said Specification, and to render their manipulation more easy, in their
application to general loads, or to special purposes such as when employed as ash-
hoists or Steering Gears-For these purposes I construct the apparatus as follows:-
:―
(1st.) I substitute in place of the wheels with double clutch, described in aforesaid
Specification, as carried by the secondary shaft, either one or two toothed wheels
fastened together, fitted on a feather or feathers, to slide on said secondary shaft,
working alternately into corresponding pinions, one on first part of main shaft and the
other attached to an eccentric or eccentrics; according as desirable to work the winch
by hand or other power. By a simple combination of one clutch on second part of
main shaft, a double armed lever with two or more cods, and a small shaft with crank
or eccentric or other equivalent means, actuated by a wheel or lever; the aforesaid
wheel or two wheels on said secondary shaft, and said clutch on second part of main
shaft, are so manipulated that the transition from hand to other motive power, and
vice versa is readily made.
(2nd.) I make the pulley or barrel a seperate piece, but connected to the second
internally pitched wheel in first modification of combination of wheels, described in
aforesaid Specification, either by bolts, pins, or projecting lugs fitting into corre-
sponding holes or recesses formed either on one end of pulley or barrel, or in web of
said internally pitched wheel; and so arranged that on removing the cover, mentioned
in aforesaid Specification as closing the opening in Standard, the externally pitched
pinion or pinions, the second internally pitched wheel, and the eccentric, described in
first modification; or the externally pitched pinion, eccentric, and crosspiece or its
equivalent, described in second modification of combination of wheels; as also the
pulley or barrel may be taken out, through said opening when desirable, without
removing, or disturbing the fastening of, the standard carrying the combination of
wheels.
(3rd.) I attach to either part of main shaft, a friction wheel or roller (which may be
grooved or plain) working in contact with another friction wheel or roller attached to
secondary shaft; and thus constitute a frictional connection between the engine or
engines and the eccentric or eccentrics when desirable to allow the winch to work
automatically at any time the said eccentric or eccentrics being held in proper relative

page_text: angular position to the crank pin of said engine or engines by the friction during the
time the winch is working-The friction being so tempered as to be able to overcome
the inertia of said secondary shaft, and at the same time to be easily brought to a
state of rest by slight frictional pressure on a hand wheel fastened to said secondary
shaft.
(4th.) 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
Fastened on said second part of main shaft is a plate or disc, having one or more slots
or guides (either straight or curved) formed in or on it; on one side of the eccentric
or eccentrics, which actuate the valve or valves of aforesaid engine or engines (and
which I shall call the main eccentric or eccentrics) are corresponding pins or guides
which fit and slide in or on said guides in or on said plate or disc-In said main
eccentric or eccentrics there is an elongated hole passing through, in which or in
guides formed in or on the other side of main eccentric or eccentrics, a secondary
eccentric works This secondary eccentric is attached to a pinion communicating with
a wheel on said secondary shaft described in aforesaid Specification; and so arranged
that on turning said secondary shaft, the main eccentric or eccentrics is or are shifted
across said second part of main shaft, in such a manner that the engine or engines
described in aforesaid Specification may be started or reversed at pleasure.
(5th.) In place of either the third or fourth modification of valve
gear described in
aforesaid Specification, I subsitute an arrangement of main eccentric or eccentrics
with elongated hole passing through, shifted by a secondary eccentric attached to a
pinion loose on a stud or other shaft supported by one or both of the standards
described in aforesaid Specification, said pinion communicating with a wheel on
aforesaid secondary shaft, said main eccentric or eccentrics being guided along guides
in or on a plate or disc fastened on said other shaft or on a sleeve loose on said other
shaft or stud, and said plate or disc 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.
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 hereto appended-that
is to say In the drawings similar parts are referred to by the same numbers-
Figures 1 & 2, 3 & 4 illustrate two different arrangements of the improvement first
mentioned Figures 5, 6 & 7 shew the second mentioned improvement-Figures 8 & 9
shew the third mentioned improvement and Figures 10 & 11, 12 & 13 represent the
two modifications of valve gear described as the fourth and fifth improvements
respectively.
(1st.) In Figures 1 & 2, 30 & 27 are two toothed wheels fastened together, fitted on
feathers to slide on the secondary shaft 26, so that the wheel 30 may work into the
pinion 12 on part 9 of main shaft, or the wheel 27 may work into the pinion 22
attached to the eccentric 21, as may be desired to work the winch by hand or other
power On the part 11 of main shaft a clutch 16 is fitted to slide on feathers; in a
groove in this clutch, cods are fitted, connected to one arm of the lever 40, the other
arm of which has a cod fitting into a groove on the boss of the two wheels 30 & 27,
into his latter groove there is also fitted a cod connected with a small crank or
eccentric on one end of the shaft 37, having a hand wheel 36 at the other end-By
this arrangement, on turning the hand wheel 36, the clutch 16 and the wheels 30 & 27
are made to slide simultaneously along their respective shafts, 11 and 20, so that when
the clutch 16 is out of gear with its counterpart, the wheel 30 is in gear with the.
pinion 12, and thus the winch may be wrought by hand; and when the clutch 16 is in
gear, the wheel 27 is in gear with the pinion 22, so that the winch may be actuated by
steam or other power.
Figures 3&4 are two views of another arrangement in which the groove in the
boss of the two wheels 30 & 27 is beyond the wheels, and the double armed lever 40

page_text: is connected with the cods fitted into the groove in the clutch 16 by means of two
links 69.
(2nd.) In Figures 5, 6 & 7-the pulley or barrel 5 is made a seperate piece, but
connected to the internally pitched wheel 4 by projecting lugs 70, formed, on the end
of the pulley or barrel 5, fitting into corresponding holes or recesses formed in the
wob of the internally pitched wheel 4, and so arranged that on removing the cover 3.
mentioned in aforesaid Specification as closing the opening in Standard 1, the
externally pitched pinion or pinions, the second internally pitched wheel 4. and the
eccentric, described in first modification; or the externally pitched pinion, eccentric
and crosspiece or its equivalent, described in second modification of combination of
wheels;..as also the pulley or barrel 5, may be taken out through said opening, when,"
desirable, without removing or disturbing the fastening of the Standard 1 carrying the,
combination of wheels.
(3rd.) In Figures 8 & 9-71 is a friction wheel attached to the secondary shaft 26,
working in contact with another friction wheel 72 attached to either the part 9 or
part, 11 of. main shaft, thus constituting a frictional connection between the engine or
engines and the eccentric or eccentrics, when desirable to allow the winch to work
automatically at any time--The wheel 72 is adjustable by screws so that the amount
of friction between the wheels 71 & 72 may be tempered so as to be able to overcome
the inertia of the said secondary shaft 26, and at the same time to be easily brought to
a state of rest by slight frictional pressure on a hand wheel fastened on said secondary
shaft 26.
(4th.) Figures 10 & 11 represent one modification of valve gear which may be
substituted in place of either the first or second modifications of valve gear described
in aforesaid Specification. A plate or disc 73 is fastened on part 11 of main shaft,
having two slots or guides 74 formed in it; into these, are fitted and slide two
corresponding guides 75 formed on one side of the main eccentric or eccentrics 21,
which actuate the valve or valves of aforesaid engine or engines-Passing through
said main eccentric or eccentrics 21, there is an elongated hole, in which or in guides
formed in or on the other side of main eccentric or eccentrics 21, a secondary
eccentric 76 works-This secondary eccentric 76 is attached to a pinion 22 com-
municating with a wheel 27 on said secondary shaft 26, described in aforesaid
Specification; and so arranged that on turning said secondary shaft 26, the main
eccentric or eccentrics. 21 is or are shifted 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.
(5th.) Figures 12 & 13 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 a main eccentric or eccentrics 21 with
elongated hole passing through, shifted by a secondary eccentric 76 attached, either
by boss or sleeve, to a pinion 22 loose on a stud 64 or other shaft supported by one or
both of the standards described in aforesaid Specification; said pinion 22 communi-
cating with a wheel 27 on aforesaid secondary shaft 26; said main eccentric or
eccentrics 21 being guided along guides 75 in or on a plate or disc 73 fastened on
said other shaft or on a sleeve loose on said other shaft or stud 64; and said plate or
disc 73 being connected with part.11 of main shaft, by means of a wheel 62 attached
to it communicating with another 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 eithe 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.
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 :-

page_text: and crank as hereinbefore described and illustrated in the accompanying drawings, or
any modification. thereof.
2nd. In Winches, I claim the making the pulley or barrel a seperate piece, but
connected to the combination of wheels by bolts, pins or projecting lugs fitting into
corresponding holes or recesses. And the arrangement by which the several parts
hereinbefore named, with the pulley or barrel may be taken out through the opening.
in standard carrying the combination of wheels; all substantially as hereinbefore
described with reference to the drawings hereunto appended.
3rd. In Winches, I claim the application of friction wheels to constitute a frictional
connection between the Engine or Engines, and the eccentric or eccentrics, when
desirable to allow the winch to work automatically at any time; substantially as
described hereinbefore with reference to the accompanying drawings.
4th. In Winches, I claim the application of either modification of the combination
of plate or disc guiding main eccentric or eccentrics with elongated hole passing
through, shifted by secondary eccentric attached to pinion loose on main shaft, or on
stud or other shaft supported by one or both standards of winch, or on sleeve thereon;
substantially as herein before described with reference to the accompanying drawings..
