Improvements in and connected with Winding Drums.
DANIEL DOUGLAS 5 Kingston Terrace Hull Engineer FRANCIS SOMERSCALES
20 Park Grove Hull Naval Architect 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:-
Our invention consists first of a barrel or shaft having a right and left handed
screw formed on its outer surface, secondly of supports to hold the barrel in
position these supports can be secured either to a winding engine framework or
elsewhere as may be convenient, thirdly of a tongue piece fitted to the barrel and
so made that with a continuous revolving motion of the barrel it will travel to and
fro from end to end of the barrel, fourthly attached to the tongue piece are two
vertical and one horizontal rollers arranged to slide with the motion of the tongue
on a bearing bed which extends above and for the length of the barrel, fifthly
attached to the vertical roller bed or to the tongue piece is a pointer and on the
bearing bed of the rollers figures are placed which indicate the total number of
turns of rope that can be wound on the winding engine drum from end to end,
sixthly the vertical roilers can be made so that they can be drawn apart from each
other or removed, seventhly the above described apparatus may be driven by means
of cog wheels, worm wheels by cranks, or by an endless chain by which the barrel.
may be made to revolve in connection with the drum of a winding engine; and the
said apparatus will when connected to an engine used for winding ropes cause the
turns on the barrel of the same to be laid evenly side by side.
In the drawing annexed,
Fig. 1 is a plan of the apparatus, and part of the framework and drum H of a
winding engine to which it is connected by the supports B. This figure shews the
horizontal roller and the vertical rollers D in position on the bearing bed F which
is shewn with its connection to the supports B at the ends and broken off for a
space to shew the shaft A with the right and left handed screw on it. The
wheels I. I. at the end of the shaft A of the apparatus and at the end of the drum
shaft which are formed to receive the chain E shew one mode of connecting the
apparatus to a winding engine drum and the size of these wheels can be varied to
alter the rate of travel of the rollers to and fro on the bearing bed, so as to suit the
travel of different sized ropes. The rope is marked L.
Fig. 2 is an end elevation of the apparatus and an end elevation in part of
the framework and drum of a winding engine, this fig. shews the shape of the
support B and the chain wheel I at the end of the shaft. The support can be
bolted to the framework or formed in one piece with it as desired.
Figure 3 is a section through the centre of the shaft of the apparatus and shews
the shaft A, the tongue piece C', the rollers D and the bearing bed F.
The tongue piece is attached to a foundation piece K of the rollers D by a screw
and a nut, and the foundation piece of the roller is shaped so as to slide on
the bearing bed which has a slot cut in it from end to end for the tongue
piece to slide in and to form a guide for the foundation piece, the vertical rollers
are attached to the foundation piece by spindles having nuts or cotters to keep
them in place.
The tongue piece is shaped so as to fit the thread on the shaft, and with
sufficient clearance to enable it to turn at the ends and reverse its motion.
Figure 4 is a front elevation of the apparatus and shews the end supports B the
shaft A with the right and left handed thread on it. The rollers D, the bearing
bed F, the roller foundation piece K, and the chain wheel I.

page_text: The pointer G is attached to the foundation piece of the rollers, and the bearing
bed is marked from end to end, the divisions being made to correspond with the
number of the turns of rope from side to side of the drum, so that when the
apparatus is connected to the drum, and set in motion, the pointer will indicate
the number of turns of rope that are wound on the drum from one side of the
same.
The rope L is shewn on the drum, and led between the vertical rollers on
Figure 1 and Figure made so that they can be drawn apart from each other or
removed, seventhly the above described apparatus may be driven by means of cog
wheels, worm wheels by cranks, or by an endless chain by which the barrel may be
I made to revolve in connection with the drum of a winding engine; and the said
apparatus will when connected to an ergine used for winding ropes cause the turns
on the barrel of the same to be laid evenly side by side.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
First. The method herein described of constructing an apparatus for auto-
matically regulating the turns of a rope on a winding engine drum which method
consists in causing the vertical rollers D through which a rope may pass, to travel
to and fro from end to end of a shaft by means of the tongue piece C₁ which runs
in the thread of a right and left handed screw on the said shaft, and that the said
rollers can be drawn apart or removed so as to enable an obstruction on the rope
travelling between them to pass through; and we further claim that the apparatus
as described may be fixed to a steam winch or any winding engine or that it may
be fixed to an independent support or foundation, and connected to a winch or
winding engine by any of the methods described whereby the barrel of the
apparatus can be made to revolve in connection with a winch or winding engine;
and we further claim that the pointer attached to the roller bed or tongue piece
can be made as described and with marks on the bearing bed of the rollers
representing the number of turns of the rope from each end of the drum of the
winding engine, and further that the said apparatus is in gear when the rollers are
so placed that the pointer is coincident with the figure which indicates the number
of turns of rope that are on the drum of the winding engine to which the apparatus
is attached.
