I, JOHN BROKENSHIRE FURNEAUX, of The Victoria Works, Gateshead, in
the County of Durham, Engineer, do bereby declare the nature of this invention
to be as follows:-
This invention has reference to a construction of winch, hoist or the like
(hereinafter called a winch) adapted to be driven at will either by mechanical or
manual power and in which the driving mechanism can be quickly put in and out
of action without necessarily stopping the motion of the main driving shaft.
One arrangement of winch according to this invention is as follows:-
On the shaft which carries and drives the winch barrel, is fixed a toothed wheel
arranged to be driven by hand power from a toothed pinion through a second or
idle toothed wheel or pinion that is so mounted and arranged that it can be caused
to gear simultaneously with the first mentioned wheel and pinion, or be put out of
gear with one or other or both of them at will. The handles for working the
winch by hand can be fixed upon the shaft upon which the first mentioned pinion
is fixed, or be arranged to operate this shaft through other toothed wheels and
shafts as may be desirable.
For operating the winch mechanically there is employed an electric motor to the
shaft of which is attached a worm that drives a worm wheel. On the worm wheel
shaft is fixed a toothed pinion with which constantly gears an idle pinion mounted
to rotate freely upon a pin carried by one end of a lever mounted to turn on a
trunnion or bearing concentric with the worm wheel shaft. The other end of the
lever is arranged to be under the control of an operator, so that by partly turning
the lever about its fulcrum, the centre of the idle pinion can be caused to travel in
a circular path which has its centre coincident with the centre of the worm wheel
as indicated above. The arrangement is such that the idle pinion can, by the
turning movement of the lever be quickly put in and out of gear with the toothed
wheel on the shaft carrying the winch barrel. The lever carrying the idle pinion
may be operated by a rod working through a gripping device by which the rod,
lever and idle pinion can be readily fixed in their operative or inoperative
positions; or the lever may be operated by means of a screw rod working through
a nut.
The electric motor may advantageously be enclosed in a casing at the base of
the winch and so that the armature shaft with worm thereon is vertical.
In a modified construction the toothed wheel on the shaft carrying the winch
barrel is arranged to be driven manually by a toothed pinion that gears direct with
it and is fixed on a shaft to which crank handles are also fixed. The electrical
driving mechanism is similar to that hereinbefore described.

I, JOHN BROKENSHIRE FURNEAUX, of The Victoria Works, Gateshead, in
the County of Durham, 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 has reference to a construction of winch, hoist or the like
(hereinafter called a winch) adapted to be driven at will either by mechanical or
manual power and in which the driving mechanism can be quickly put in and out
of action without necessarily stopping the motion of the main driving shaft, as
I shall now describe with reference to the accompanying drawings wherein Fig. 1
is an end'elevation and Fig. 2 a side elevation, showing one construction of winch
according to this invention.
On the shaft 1 which carries and drives the winch barrel 2, is fixed a toothed'
wheel 3 adapted to be driven by hand power from a toothed pinion 4 which is
fixed upon a shaft 5 and is in gear with the toothed wheel 3. The handles 6 for
working the winch by hand can be fixed upon the shaft 5 upon which the pinion 4
is fixed, or be arranged to operate this shaft through other toothed wheels and
shafts as may be desirable.
For operating the winch mechanically, there is employed an electric motor 7 to
the armature shaft 8 of which is fixed a worm 9 that drives a worm wheel 10. On
the worm wheel shaft 11 carried in suitable bearings 12, is fixed a toothed
pinion 13 with which constantly gears an idle pinion 14 mounted to rotate freely'
upon a pin 15 carried by one arm 16 of a lever mounted to turn on a trunnion or
bearing concentric with the worm wheel shaft, or, as shown, upon the said shaft
itself. The other arm 16 of the lever is arranged to be under the control of an
operator, so that by partly turning the lever 16-16 about its fulcrum, 'the centre
of the idle pinion 14 can be caused to travel in a circular path which has its centre
coincident with the centre of the worm wheel 10 as indicated above. As will be
seen, the arrangement is such that the idle pinion cau, by the turning movement of
the lever 16-16" be quickly put in and out of gear with the toothed wheel 3, with-
out stopping the electric motor. The lever 16, 16° may conveniently be operated
by a rod 17 working through a gripping device comprising for example jaws 18 and
tightening up screw 19 and whereby the rod 17, lever 16, 16 and idle pinion 14 can
be readily fixed in their operative or inoperative positions at will. Or the
lever 16, 16 may be operated by means of a screw rod working through a swivelling
nut, as well understood.
The electric motor may advantageously be enclosed, as shown, in a casing 20 at
the base of the winch and so that the armature shaft 8 with worm 9 thercon is
vertical.
Instead of the hand driven pinion 4 gearing direct with the wheel 3, as shown,
it may gear indirectly therewith through an idle wheel or pinion mounted and
controlled in a similar manner to the idle pinion 14 so that it can be put in and
out of gear with the toothed wheel 3 or pinion 4 according as it is desired to put
the shafts 1 and 5 in or out of driving connection with each other.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
My improved winch or hoist constructed substantially as hereinbefore described
