COMPLETE SPECIFICATION.
Improvements in Rope Haulage and Clips therefor.
We THOMAS HEPPELL of Birtley in the County of Durham Mining Engineer
and JOHN WRIGHT of Urpeth Colliery in the County of Durham Engineer and
ARTHUR PIERCE STOKER of Birtley aforesaid Colliery Manager 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 present invention relates to improvements in rope haulage and the object
thereof is to arrange mechanism in combination with a clip whereby the said clip
may be automatically attached to the rope by the movement of the corf or load
along the track, which incchanism by the continued movement of the corf
automatically adjusts itself ready for the automatic attachment of the clip to the
rope by the movement of a subsequent corf or load to attain which we construct a
clip and connect it to the corf or load and employ mechanism in conjunction
therewith substantially in the manner set forth in the accompanying sheet of
drawings which are to be taken as part of this Specification and read therewith.
Fig. 1. is a side elevation of clip we prefer to use in conjunction with our
improved mechanism shown attached to rope. Fig. 2. is a similar elevation thereof
showing clip detached from rope, and Fig. 3 is an elevation thereof taken at right
angles to Fig. 2.
Fig. 4. is a side elevation of our improved mechanism for automatically attaching
said clip to corf or load and Fig. 5. is a plan of same.
Similar letters of reference denote corresponding parts in each view.
The clip we prefer to employ in conjunction with our improved mechanism is formed
with a stem a within which is pivotted a catch to prevent it being lifted from the corf
when fitted thereto see Fig. 4. The upper end of stem a has a fixed bottom jaw d
and hinged thereto is an upper jaw which latter has made therewith a projection
or lever d¹.
The bottom jaw d is made with a swept groove and the upper jaw
is made
with a corresponding projecting part so as to effectually grip the rope without
injuring same.
Upon the stem a and below the fixed jaw d is a fixed pin or bearing a' which
carries a bent shaped lever f. The said clip is secured to corf G by the lower part
of stem a being fitted in a socket and the catch catching through a hole in the
corf G as shown Fig. 4.
In connection with the ordinary tram line or corf road j we arrange the following
mechanism namely. We place a vertical shaft K bearing in a step and upper
support. To the upper part of said shaft K we fix a horizontal lever k³ and
arrange a runner which is carried upon a lever fixed to the vertical shaft K
aforesaid in position suitable for coming in contact with side or other convenient
part of corf.
At the lower part of said vertical shaft K we also fix another
fever to which is connected a rod which couples up to one end of a vertical
lever L pivotted to a bracket or box or carried in supports l'. The upper end of
said lever L is connected by means of a rod 13 to a lever which is fixed to one
end of a horizontal shaft M. The said shaft M passes under one of the rails at
right angles thereto and receives a suitable bent lever m³ arranged in position
shown.
Elevated above the corf and in the centre plane or thereabouts of track or
tramway we fix a guide or conductor P.
Our improved mechanism attaches the clip to the rope automatically in the

page_text: following manner. The corf G shown to right at Fig. 4. has the hinged jaw d
and its lever or projection thrown over or open and the catch or lock leverf is
clear thereof. When in this position the rope R is free to travel without moving
the corf G. The corf G is then pushed or pulled until the clip arrives at the
guard or conductor P when the projection or lever presses against the bent part
of said guide P and the upper or hinged jaw d is thereby thrown over to closed
position upon the rope R, and as the corf G travels past the vertical shaft K,
the runner comes in contact with the side of said corf G thereby causing the
lever to move in a lateral direction until it presses the catch or lock lever over
the projection or lever d' thus locking the clip to the rope automatically which will
then move the corf or load along the track and as the corf G travels along its
under part comes in contact with the bent lever m¹ so depressing the same and
simultaneously causing the levers and in conjunction with the rods and 13 to
pull back the levers and rod with runner to original position ready to
automatically attach the next corf by means of the clip to the rope as will be
obvious.
We would have it understood that we do not claim per se the haulage clip
bereinbefore described but
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. In rope haulage the combination with a clip such as described or a mere
modification of such clip of mechanism arranged so that the movement of the corf
or load causes a part d¹ of movable jaw to come in contact with a guide or
conductor P so closing said jaw d³ upon the rope R and also subsequently by coming
in contact with a runner or similar device moves a lever 3 laterally so as to
move a lock lever or catch of clip in order to cause the clip to grip firmly the
rope R substantially as described and illustrated.

2. In rope haulage and mechanism for automatically attaching the clip to the
travelling rope the combination of a bent depressable lever m² with levers
and and connections 13 and 8 and vertical shaft K substantially as described and
illustrated and for the purpose specified.
