I, MARK ARCHER, of No. 4 Elysium Lane, Bensham, in the town of Gateshead-
on-Tyne, and County of Durham, Coal Fitter, do hereby declare the nature of this
invention to be as follows:-
My invention of improvement in winches consists in a means of simplifying and
lessening cost of winches, and producing a more efficient, variable machine and is
carried out as follows:-
The frames of the winch which are of the ordinary A shape may be cast iron plate
or angle iron. Instead of the ordinary drum at present used, I employ a series of
bars of wrought or cast iron, which bars are made convex externally to an extent at
least equivalent to that which would be produced if all the bars while in their position
were turned upon a lathe having its centre the same as the centre of revolution of the.
drum. These bars are carried between wrought or cast iron plate ends in one of
which ends they are rivetted or otherwise secured while they are allowed to slide
through holes in the other end. These ends or flanges of the drum so formed are
both securely fixed to the shaft or spindle, with which they revolve in the direction of
its revolution and one of them is also so fixed in the direction of the length of that
spindle, whereby without affecting the relative position of the cheeks in regard to their
revolution they may be brought nearer to each other or be further separated so as to
shorten or lengthen the barrel. By which means the length of the barrel may be
adjusted at will so as to suit different sizes or lengths of rope.
A further part of my invention consists in an improved manner of holding the
pinion of the winch in the position of being in or out of gear. I form a sliding
block which slides upon the top cross stay of the A frames forming the body of the
winch. This sliding block is secured in either of two positions by means of a tongue
piece fitted into it which may be dropped into one of two notches in the cross stay on
which the block slides. The sliding block has two lugs upon it, between which lugs
the pinion of the winch is placed, the driving spindle running through both the lugs
and the pinion, so that the position of the sliding block determines the position of the
pinion, in or out of gear, and the tongue piece of the sliding block holds it in the desired
position. The pinion is of course free to slide on its driving spindle in the way of
the length of the spindle, but is caused to revolve by means of a key or similar
arrangement with the spindle on which it slides.

page_text: Improvements in Winches.
I, MARK ARCHER, of No. 4 Elysium Lane, Bensham, in the town of Gateshead-
on-Tyne and County of Durham, Coal Fitter, 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:-
My invention of improvements in winches consists in a means of simplifying and
lessening cost of winches, and producing a more efficient, variable machine; and is
carried out as follows:-reference being had to the drawing hereunto attached in
which I have shewn the parts of a winch peculiar to my invention but not such parts
as are common to all winches.
The frames of the winch which are of the ordinary A shape may be cast iron, plate,
or angle iron. Instead of the ordinary drum at present used I employ a series of bars
of wrought or cast iron which bars are made convex externally to an extent at least
equivalent to that which would be produced if all the bars while in their position were
turned upon a lathe having its centre the same as the centre of revolution of the
drum. Fig. 1 is a longitudinal and cross section of one of these bars. In the cross
section it will be observed that the sharp edges which would result from turning the
bars when in their final position as above described are taken off, this I do, so as to
avoid under wear of the rope, but the exact shape of the bar is in no way material to
my invention. These bars are carried between wrought or cast iron plate ends, in one
of which they are rivetted or otherwise secured while they are allowed to slide through
holes in the other end. These ends are shewn in Fig. 2, with one bar A. in position which
is fixed by rivetting in the end B. and free to slide through the end C. through which
I have shown part of it projecting. Fig. 3 is an end view of the loose end with one
bar in position. These ends or flanges of the drum so formed are both securely fixed
to the shaft or spindle with which they revolve in the direction of its revolution, and
one of them B is also fixed in the direction of the length of that spindle whereby
without affecting the relative position of the cheeks in regard to their revolution they
may be brought nearer to each other or be further separated so as to shorten or
lengthen the barrel. In Figs. 2 and 3 I have shewn this spindle to be square and the
opening in the loose cheek C to be also square and nearly fitting to the spindle, but
it may also be made round with a long key on the spindle, and a key way in the
sliding end C. The spindle is fixed in the end B. and the whole revolves on the
bearings D. and E. I find in practice that the strain of the rope producing pressure
on the bars is usually adequate to retain the loose cheek in any position in which it
may be placed, but if desired I may corrugate the inside of the bars and make corre-
sponding elevations in the holes of the loose cheek so as more effectually to lock it
into its position against the outward thrust of the rope.
A further part of my invention consists in an improved method of holding the
pinion of the winch in the position of being in or out of gear. I form a sliding

page_text: block Fig. 4 which slides up the cross stay F. of the A frames forming the body of
the winch. This sliding block is secured in either of two positions by means of a
tongue piece G fitted into it which may be dropped into one of two notches H and I.
in the cross stay F on which the block slides. The sliding block has two lugs upon
it J and K between which lugs the pinion L. of the winch is placed, the driving
spindle M running through both the lugs and the pinion so that the position of the
sliding block determines the position of the pinion in or out of gear, and the tongue
piece of the sliding block holds it in the desired position. The pinion is of course free
to slide on its driving spindle in the way of the length of the spindle, but is caused
to revolve by means of a key or similar arrangement with the spindle on which it
slides.
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. The method of shortening or lengthening the barrel of a winch, substantially
as described.
2nd. The method of holding the pinion of a winch in or out of gear substantially
as described.
