We, ROBERT MARSHALL, of 6, Great Winchester Street, in the County of
London, Engineer, and WILLIAM HOPWOOD, of Ashton Road, Denton, near Man-
chester, in the County of Lancaster, Engineer, do hereby declare the nature of
this invention to be as follows:-
When a long rope has to be wound on a drum, it is objectionable to employ
a long drum taking numerous convolutions of the rope because of the obliquity
of the pull tending to drag the rope off the head pulley and to lay the convolu-
tions too far apart or to make them override each other on the drum. This
invention relates to an arrangement of winding apparatus in such a manner
that a long winding drum may be employed free from the objection mentioned.
For this purpose, we fix parallel to the axis of the drum a rail or track on
which there is a truck having mounted on it a grooved guide pulley. The
axis on which the pulley revolves is at right angles to the axis of the drum,
and the groove of the pulley is in a plane tangential to the periphery of the
drum. The truck is attached to an endless chain worked by a sprocket wheel
which is driven by worm gear from the shaft of the drum, so that as the drum
revolves winding the rope on or off, the guide pulley travels lengthwise guiding
the successive convolutions on to or off from the drum at proper intervals apart
without involving any obliquity in the direction of the rope, which passes from
the travelling pulley in a direction parallel to the axis of the drum. A weight
may be employed to balance the strain on the pulley.
In order that the strains may be well balanced, however, we prefer to employ
two drums both on one shaft and to arrange the rope so that while both drums
revolve in the same direction, the rope is wound on to the one and off from the
other. Each drum has its own track or rail, guide pulley and truck, and both
trucks may
be attached to the one chain, so that they may move in opposite direc-
tions, the one in an upper and the other in a lower plane, tangential to the respec-
tive drums.
The pulley truck in each case instead of being caused to travel by an endless
chain, may have a nut engaged with a screw spindle mounted parallel to the
axis of the drum and driven from it by suitable gear.

page_text: this invention and in what manner the same is to be performed, to bo; parti-
cularly described and ascertained in and by the following statement:-
When a long rope has to be wound on a drum, it is objectionable to employ
a long drum taking numerous convolutions of the rope because of the obliquity
of the pull tending to drag the rope off the lead pulley and to lay the convolu-
tions too far apart or to make them overrido each other on the drum. This
invention relates to an arrangement of winding apparatus in such a manner
that a long winding drum may be employed free from the objection mentioned.
For this purpose, we arrange drums as we shall describe referring to the
accompanying drawings. Fig. 1 is a side view Fig. 2 is a plan and Fig. 3 is
an end view of a pair of drums arranged according to our invention. Figa. 4,
5 and 6 are corresponding views, shewing a modification. a and bare a pair of
drums, parallel to the axis of each of which we fix a rail or track c on which
there is a truck d having mounted on it a grooved guide pulley,e. The axis on
which the pulley e revolves is at right angles to the axis of the drum a or 5,
and the groove of the pulley is in a plane tangential to the periphery of the
drum. The truck d is attached to an endless chain f worked by a sprocket
wheel g which is driven by worm gear h from the shaft of one of the drums,
so that as the one drum revolves winding the rope on, the other winding it off,
the guide pulleys e travel lengthwise guiding the successive convolutions on to.
or off from each drum at propor intervals apart without involving any obliquity
in the direction of the rope & which passes from the travelling pulley in a direc-
tion parallel to the axis of the drum. Obviously a single drum may be pro-
vided as described with guide pulley moved along a track but in order that the
strains may be well balanced we prefer to employ two drums as shewn both on-
one shaft and to arrange the rope so that while both drums revolve in the same:
direction, the rope is wound on the one and off from the other. Each drum
has its own track or rail c, guide pulley e, and truck d, which may be connected
to the drums separately or both trucks may be attached as shewn to the one
chain, so that they move in opposite directions, the one in an upper and the other
in a lower plane tangential to the respective drums.
The pulley truck in each case, instead of being caused to travel by an end-
less chain, as shown in Figs. 1, 2, and 3 may have a nut engaged with a screw
spindle mounted parallel to the axis of the drum and driven from it by chain m
or other suitable gear as shewn in Figs. 4, 5 and 6.
In this case the drum from which the rope is unwound, may be unclutched as
shewn in Figs. 4 and 5.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the sanic is to be performed, we declare that what
we claim is :-
1. In winding apparatus, the combination of a rope drum, a guide pulley
mounted in a plane tangential to the periphery of the drum on a carriage caused
by gear connecting it to the drum to travel in a track parallel to the axis of
the drum, substantially as and for the purposes set forth.
2. The combination of two drums on one shaft with their guide pulleys car-
riage and tracks, both carriages moved by a chain driven by worm gear from
the drum shaft, substantially as described with reference to Figures 1, 2 and 3.
3. The combination of two drums on one shaft with their guide pulleys, car-
riages and tracks each carriage moved by a screw driven from the drum shaft,
substantially as described with reference to Figs. 4, 5 and 6.
