Office of the Commissioners of Patents with his Petition, on the
15th August 1867..

I, EDWARD ORMEROD, of Atherton, in the County of Lancaster, Engineer,
do hereby declare the nature of the said. Invention for "CERTAIN IMPROVE
MENTS IN SAFETY APPARATUS TO BE EMPLOYED, FOR PREVENTING ACCIDENTS IN
WINDING COALS AND OTHER MINERALS FROM MINES," to be as follows:-
.
The Invention relates to a description of link or shackle which is interposed
between the winding rope and the cage or receptacle, and which is designed
for the purpose of rendering such attachment either permanent or releasing by
self-acting means, according to its position when employed for raising or

page_text: lowering weights, coal, or other minerass, the said link being so arranged that
in the event of the cage being "overwdund" it is released from the rope, and
at the same time retained at the point where the link became uncoupled or
disconnected.
The improvements consist in the employment and use of a link or shackle
formed of three plates placed side by side, and connected together at the
middle of their length by a central pin or stud, upon which the plates may
turn; in these plates grooves or slots are formed in which the shackle pins
that connect the rope with the cage are contained.
The formation of the slots and relative positions of the plates and slots and
shackles will be more readily understood on reference to the Drawings here-
unto attached, in which Fig. 1 represents a front elevation of the link às it
would appear when duly connected and forming a permanent union between
the rope and the cage; Fig. 2 represents a side view of the same; and Fig. 3
represents a front elevation of the link as it would appear when the rope is
disconnected and the cage retained upon the top flange of the disconnecting
tube.
In Figs. 1, 2, and 3, a, a, are the outside plates of the link, and b is the
inside or intermediate link; these links are placed side by side, and connected
together by the central pin or stud c, upon which the plates turn or move
on a centre. The two outside 'plates' are provided at the top with curved-
slots d, d, each having an opening extending to the edge of the plates, and the
bottom slots e, e, are formed in the plates and do not extend to the edge
thereof, and have no exit. for the lower shackle pin; the intermediate pin b
is also provided with two vertical slots g and h, the upper slot g being open at
the top, and the lower slot h closed. These slots when combined in the posi-
tion shewn in Fig. 1 are arranged so as to embrace and retain the pin i
connected with the suspending or winding rope, and the pin le connected with
the cage, hoist, or receptacle. A small hole r, which corresponds in each plate
(when in the position shewn) is filled by a soft metal pin, which is inserted
through the plates to prevent them moving without the necessary pressure,
and which 'then forms a permanent union or link. When in this position the
inclined edge of the intermediate plate 6 projects beyond the edges of the
other plates, as sewn in the Drawings, and in such position the rope and
cage are properly connected for working. Should however the cage be lifted
too high so as to bring it near the winding pulley the link enters the tube'm,
seen in Fig. 3; which is permanently and securely fastened at a proper
distance between' the pulley and the shaft or pit opening, and when the link
.:

page_text: has been drawn sufficiently through so as to allow the upper end thereof to
project above the flange or collar of the tube m the interior surface u of the
tube which is inclined will have forced or compressed the edge of the plate b
level or even with the other plates a and a, which will cut or break the soft
metal pin, and cause the interior vertical top slot g to force the pin i from the.
curved slots in the outside plates so as to make all the vertical slots coincide,
and one common opening out of the top of the links will be formed, thereby,
allowing the pin i connected with the rope to escape, and immediately the
catches o, o', of the links overlap and are caught by the flanges of the tube m,
whereby the release of the cage from the rope, and the retention and safety.
of 'the' cage, are simultaneously effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Ormerod in the Great Seal Patent Office on t
13th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
ORMEROD, of Atherton, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of August, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward Ormerod, Her special license that I, the said Edward Ormerod,
my executors, administrators, and assigns, or such others as 1, the said
Edward Ormerod, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS IN SAPETY APPARATUS' TO BE EMPLOYED FOR PREVENTING ACCIDENTS IN
WINDING COALS AND OTHER MINERALS FROM MINES," upon the condition (amongst
others) that I, the said Edward Ormerod, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to he
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.

between the winding rope and the cage or receptacle, and which is designed
for the purpose of rendering such attachment either permanent or releasing,
by self-acting means, according to its position when employed. for raising or
lowering weights, coal, or other minerals, the said links being so arranged that
in the event of the cage being overwound" it is released from the

The improvements consist in the employment and use of a link or shackle
formed of three plates placed side by side, and connected together at or about
the middle of their length' by the central pin or stud upon which the plates
may turn in these plates grooves or slots are formed, in which the shackle
pins that connect the rope with the cage are contained.
In order that the formation of the slots and relative positions of the plates,
slots, and shackles may be more clearly understood. I have hereunto attached
Sheet of Drawings made about the full size,

Fig. 1 represents a front elevation of the link as it would appear when duly.
connected, in which position it forms a permanent union between the rope and.
the cage; Fig. 2 represents a side view of the same and Fig. 3 represents a
front elevation of the link as it would appear when the rope is disconnected
and the cage retained upon the top flange of the disconnecting tube.

In Fig. 1, 2, and 3, a, a, are the outside plates of the link, and 6 is the
inside or intermediate link; these links are placed side by side, and connected
together by the central pin or stud c, upon which the plates turn, or move as
on a centre; the two outside plates are provided at the top, with curved.
slots d, d, each having an opening extending to the edge of the plates, and the
bottom slots 6, 6, are formed in the plates, and do not extend to the edge
thereof, and have no exit for the lower shackle pin; the intermediate plate 6
is also provided with two vertical slots g and h, the upper slot g being open at
the top, and the lower slot 6 closed. These slots when combined in the posi-
tion shewn in Fig. 1 are arranged so as to embrace, and retain the pin is
connected with the suspending or winding rope, and the pink connected with
the cage, hoist, or receptacle. A small hole r, which corresponds in each plate
(when in the position shewn) is filled, by a soft metal pin, which is inserted

page_text: through the plates to prevent them moving without the necessary pressure,
and which thus forms a permanent union or link when in this position; the
inclined edge of the intermediate plate 6 projects beyond the edges of the
other plates, as shewn in the Drawing, and in such position the rope and
cage are properly connected for working. Should however the cage be lifted
too high, so as to bring it near the winding pulley, the link enters the tube or
cylinder m, seen in Fig. 3, which tube or cylinder is permanently and securely
fastened at a proper distance between the pulley and the shaft or pit opening
and when the link has been drawn sufficiently through so as to allow the upper
end thereof to project above the flange or collar of the tube m the interior
surface of the tube n will have forced or compressed the edge of the plate 6
Jevel or even with the other plates a, a, which will cut or break the soft metal
pin, and cause the interior vertical. top slot g. to force the pin from the curved
slots in the outside plates so as to make all the vertical slots coincide, and one
common opening out, at the top of the links will be formed, thereby allowing
the pin i connected with the rope to escape, and the catches o, o', of the links
overlap and are caught by the flanges of the tube m, whereby the release of
the cage from the rope, and the rentention and safety of the cage are simulta-
neously effected. When the inclined edges of the plates project above the
flange of the cylinder, as seen in Fig. 2 (at the time the cage is released), the
links become locked in such position and are retained in and supported by
the tube or cylinder until the cage is uncoupled or its weight removed from
the links. This locking is effected by means of the pin k, which enters the
vertical slots in the lower ends of the plates when it is forced from the curved
slots in the outside plate of the link whilst passing into the cylinder, and is
further locked by means of a pin projecting from each side of the middle plate,
and which pin passes along inclined slots into recesses cut in the inside faces
of the two outside plates, as seen in detached view, Fig. 4, which is a section
through the line A, B, Fig. 3.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,―
First, the general arrangement and construction of the apparatus to be
employed for preventing accidents in winding coals and other minerals from
mines and other similar purposes, as herein described.
And, secondly, I claim the combination of curved slots with vertical slots
in plates or links, with or without the addition of horizontal slots; and also
the use and combination of extra slots in the outer plates and pins in the

page_text: middle one, which are employed to lock the plates together, and yet used
independently from the shackle or link pin, as herein-before described, set
forth, and fully illustrated in the Drawings attached.
.In witness whereof, I, the said Edward Ormerod, bave hereunto attached
my hand and seal, this Eleventh day of February, in the year of our
Lord One thousand eight hundred and sixty-eight.
