PROVISIONAL SPECIFICATION.
An Improvement in connection with Hooks Used for the Prevention
of Overwinding in Mines, Hoists, or other Places.
I WILLIAM ORMEROD of Atherton Terrace Atherton, in the County of
Lancaster, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to that class of disengaging or safety hooks used for the
prevention of over-winding in mines, hoists, or other places, which consists of two
or more hooked plates acting like "sister-hooks" and provided with inclined planes
which when the hook is drawn or wound too high pass through a hole in a fixed
cylinder or bell which presses in the inclines causing the upper part of the hooks to
open and release the hauling rope, and the lower portion of the same to close and
support the cage or hoist
My invention relates more particularly to the construction and fixing of the
fixed cylinder or bell which effects the above described action of the "safety-
hooks."
According to my invention 1 cast or make the bell somewhat in the usual form
but with a square flange at the top to rest securely upon the supporting wooden
beams or upon on girders, and on each side thereof below the top flange I cast or
form a flat bracket or wing by means of which the bell may be securely bolted
between the two wooden beams without the necessity for cutting away any portion
thereof to fit the outside of the bell as heretofore thereby saving labor and
avoiding the weakening of the beams.
By this construction of the bracketed bell or cylinder I am also enabled to
support the same by wrought iron girders to which it can be securely bolted by
menns of the side brackets of wings, a packing of wood or other suitable material
being preferably placed between the two metals so as to bed the same more evenly
and perfectly together.

An Improvement in connection with Hooks Used for the Prevention
of Overwinding in Mines, Hoists, or other Places.
I WILLIAM ORMEROD of Atherton Terrace, Atherton in the County of
Lancaster, Mechanical Engineer, 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 that class of disengaging or safety hooks used for the
prevention of over-winding in mines, hoists, or other places, which consists of two
or more hooked plates acting like "sister-books' and provided with inclined planes
which when the hook is drawn or wound too high pass through a hole in a ixed

page_text: cylinder or bell which presses in the inclines causing the upper part of the hooks
to open and release the hauling rope and the lower portion of the same to close and
support the cage or hoist.
My invention relates more particularly to the construction and fixing of the
fixed cylinder or bell which effects the above described action of the "safety-
hooks"
My invention will be readily understood on reference to the annexed sheet of
drawings marked with figures and letters of reference corresponding with those in
the following explanation thereot.
Fig. 1 is a plan view, Fig 2 a front elevation and Fig. 3 a side view of my
improved cylinder or bell for safety hooks for the prevention of overwinding as
adapted to be fixed upon wooden beams, and Figs. 4, 5 and 6 similar views of the
same as adapted to be fixed upon on girders.
According to my invention I cast or make the bell a somewhat in the usual form
but with a square flange b at the top to rest securely upon the supporting wooden
beams c (Fig. 1) 01 upon iron girders d (Figs. 4, 5 and 6) and on each side thereof
below the top flange I cast or form a flat bracket or wing & by means of which the
bell may be securely bolted between the two wooden beams or girders without the
necessity for cutting away any portion thereof to fit the outside of the bell as
heretofore thereby saving labor and avoiding the weakening of the beams
By this construction of the bracketed bell or cylinder I am also enabled to
support the same by wrought on guders to which it can be securely bolted by
means of the side brackets or wings see Figs. 4, 5 and 6 a packing of wood or other
suitable material being preferably placed between the two metals so as to bed
the same more evenly and perfectly together.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim 18:-
The improvement in the bells or cylinders used in connection with safety hooks
for the prevention of overwinding in mines, hoists, or other places, consisting in
the combination therewith of a square flange at the top, with two flat brackets or
wings beneath by means of which they can be securely bolted between two wooden
beams or iron girders substantially as and for the purposes herein before set forth
and illustrated by the drawings annexed.
Dated this 6th day of March 1896.
