PROVISIONAL SPECIFICATION.
An Improved Guiding Device for Coiling the Haulage Ropes or
Cords of Power Traction Ploughs.
I, GEORGE THOMAS MORECROFT, of Sutton Scotney, Micheldever, in the
County of Hants, Contractor, do hereby declare the nature of this invention to be
as follows
This invention relates to improvements in the guiding device employed for
guiding the haulage rope or cord of a traction plough upon the drum or barrel
wheel of the engine which performs the haulage.
According to the arrangement hitherto adopted a guide head has been employed
consisting of two grooved pulleys mounted in a rigid frame at a definite distance
apart through or between which the haulage rope or cord passes; the said guide
head being caused to travel to and fro laterally from end to end of the drum or
barrel wheel by means of a cam wheel and so coil the haulage rope or cord uniformly
upon the drum or barrel.
Such a guide head performs its function properly only when the pulleys are
at a correct distance apart according to the diameter of the haulage rope or cord
employed. If the rope or cord be of too small a diameter or when the pulleys have
been subjected to wear the haulage rope or cord plays loosely between the gunde
head and the drum or barrel wheel upon which it is being wound or coiled and is
apt to ride one coil upon the other in a manner to obstruct uniform winding.
My invention consists in providing a special jointed frame to carry the grooved
pulleys, one being carried in the rigid part of the frame and the other in the jointed
part so that the relative position of the two pulleys, may be so adjusted as to keep
both pulleys in constant contact with the cord notwithstanding a considerable
amount of wear.
By this arrangement the haulage rope or cord is kept taut between the guide
head and the drum or barrel wheel and consequently the guide head in travelling to
and fro from end to end of the drum or barrel wheel in the usual manner,
ensures uniform winding of the haulage rope or cord.

COMPLETE SPECIFICATION.
An Improved Guiding Device for Coiling the Haulage Ropes or
Cords of Power Traction Ploughs.
I, GEORGE THOMAS MORECROFT, of Sutton Scotney, Micheldever, in the
County of Hants, Contractor, 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 in the construction of the guiding device
employed for coiling the haulage rope or cord of a traction plough upon the drum
or barrel wheel of the engine which performs the haulage.
According to the arrangement hitherto adopted a guide head has been employed
consisting of two grooved pulleys mounted in a rigid frame at a definite distance
apart through o: between which the haulage rope or cord passes, the said guide
head being caused to travel to and fro from end to end of the drum or barrel wheel

page_text: by means of a lever operated by a cam and so coil the haulage rope or cord uniformly
upon the drum or barrel.
Such a guide head performs its function properly only when the pulleys are
at a correct distance apart according to the diameter of the haulage rope or cord
employed. If the rope or cord be of too small a diameter or when the pulleys
have been subjected to wear the haulage rope or cord plays loosely between the
guide head and the drum or barrel wheel upon which it is being wound or coiled
and is apt to ride one coil upon the other in a manner which obstructs uniform
winding.
My invention consists in providing a special jointed frame to carry the grooved
pulleys one being carried in the rigid part of the frame and the other in the
jointed part so that the relative positions of the two pulleys may be so adjusted
as to keep both pulleys in constant contact with the cord notwithstanding a
considerable amount of wear in either the pulleys or the cord.
The accompanying drawings show a special jointed frame to carry the grooved
pulleys, one being carried in the rigid part of the frame and the other in the jointed
part in the manner herein before described. In all the figures the same reference
letters indicate the same part.
Figure 1 is a side elevation of the main bracket and shank or rigid part of the
pulley frame carrying a grooved pulley.
Figure 2 is a side elevation of the adjustable cheeks or movable part of the pulley
frame carrying a grooved pulley.
Figure 3 is a side elevation of the complete frame in position for guiding the rope;
this figure also shows in dotted lines the position of the movable part of the frame
fully depressed or lowered and adjusted to clasp and coil the rope with well worn
pulleys.
Figure 4 is a front elevation of the main bracket and shank or rigid part of
the frame carrying a grooved pulley its pin forming the pivot of the movable part
or adjustable cheeks.
Figure 5 is a front elevation of the movable part or adjustable cheeks carrying
a grooved pulley.
Figure 6 is a front elevation of the complete frame with its movable part adjusted
and held in position for coiling or guiding the rope with new pulleys.
Figure 7 is an elevation of the complete frame in working position for coiling the
haulage rope upon the winding drum with its shank carried in a socket at the end
of the coiling lever upon which it is caused to rise and fall vertically in the
usual way by means of a cam movement under the engine winding drum.
a is the pivot of the movable part of the frame and is also the axis of the
grooved pulley m carried by the rigid part. is the axis of the grooved pulley n
carried by the movable part of the pulley frame; cc the studs upon which the nuts
are tightened to fix the movable part when adjusted; d d the slots which allow the
adjustment of the movable part. E is the haulage cord or rope clasped by the
pulleys m and n and guided thus straight to its right position on the drum for coiling
evenly. F is the shank of the rigid part of the pulley frame. G is the socket fixed
to the outer end of the coiling lever carrying the shank of the pulley frame and
allowing the whole frame and pulleys to swivel thereon and so adjust themselves
always to the correct angle of the draft line for the haulage rope. His the coiling
lever which rises and falls vertically by means of a cam movement generally
employed for that purpose. J is a guard attached to the winding drum cage to
prevent any coil of slack rope falling out from the drum. K is the winding drum
or haulage barrel of the engine.
The pin or bolt a which is also the axis of the grooved pulley m in the rigid part
is the pivot of the movable cheeks shown in Figures 2 and 5. When the nuts on
the studs c c are unscrewed the movable part of the frame with its pulley n may be
adjusted as required until either ends of the slots d d come in contact with the
studs c c and by tightening the nuts on the ends of these studs c c both pulleys are

page_text: held or maintained in a rigid position each being in contact with the rope in order
to guide and conduct it in a direct line to its proper position for coiling uniformly
on the drum.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner, the same is to be performed, I declare that what I
claim is :-
1. The construction of jointed and adjustable pully frames or devices for guiding
or coiling the haulage ropes or cords of power traction implements substantially
in the manner herein before described.
2. The construction of jointed and adjustable pulley frames or devices for guiding
or coiling the haulage ropes on winding drums in such a manner that the one part
carrying a pulley may be fixed or rigid and the other part also carrying a pulley is
made adjustable by moving round the pin or axis of the pulley in the fixed part
substantially as described.
