PROVISIONAL SPECIFICATION.
Improvements in Colliery Cages, Hoists, and other similar Lifting
Apparatus, to Arrest the same in case of Accident, also Partly
Applicable to Hauling Apparatus.
We PETER FOULKES of Dean Bank, Moston, Newton Heath near Manchester Sign
Writer and CHARLES CLAY of 18 Dale Street, Manchester, Hat Trimming Dealer do
hereby declare the nature of our said invention to be as follows
:-
In performing our invention we employ weighted cam levers applied to the cage
or hoist and connected by their longer arms to the winding rope so as to hold off and
keep their shorter arms or cams from coming into contact with the guide rods or
their equivalents so long as the winding rope is intact but in case of the winding
rope breaking the said weighted lever aris drop and so allow their shorter arms or
cams to grip the guide rods thus effectually locking the cage or hoist in position and
arresting the descent of the same.
A modification of our improved weighted gripping lever is applicable for hauling
purposes in Collieries-Quarries, Brick-yards, Tramways and other places where
hauling is effected by endless ropes. In this case the weighted lever is applied to the
side of a shoe which surrounds the rope and between which and the rope the grip
takes place from this shoe the hook projects for connecting with the wagon, weight or
other object to be hauled.
In case of requiring to disconnect the lever is simply thrown forward and thus
releases the short arm from contact with the hauling rope.

COMPLETE SPECIFICATION.
Improvements in Colliery Cages, Hoists, and other similar Lifting
Apparatus, to Arrest the same in case of Accident, also Partly
Applicable to Hauling Apparatus.
We PETER FOULKES, Painter of Dean Lane Moston, and CHARLES CLAY Trimming
Merchant of 18 Dale Street Manchester, both in the county of Lancaster 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 Improvements apply to an apparatus for preventing the descent of Colliery
Cages, Hoists or other similar Lifting Apparatus in the event of the winding rope or
chain breaking It is also applicable for Hauling purposes where endless ropes are
used It consists of an excentric jaw and lever attached to a Bracket in a forin best
suited for the purpose herein described.
When applied to Colliery Cages and other similar lifting apparatus it consists of
slotted Brackets, which are fixed to the top of the Cage, and through which the con-
ducting ropes or guides pass. The eccentric jaw and lever are secured to the aforesaid
slotted Brackets by means of a centre pin or stud, and on which the eccentric jaw
works, the end of the lever is held to the chains by which the Cage is suspended by a
hook or smaller chain and so long as the winding rope or chain remains intact it so
keeps the eccentric jaw free of the conductors so as to allow the Cage to be worked
freely up or down.
When the winding rope breaks, the eccentric jaw is brought to bear upon the con-
ductors by the levers being pulled down by a spring attatched to it and the top of the
cage. The moment the eccentric jaw comes in contact with the conductors the weight

page_text: of the cage itself will cause it to clutch the conductors and prevent its fall or
descent.
In its application for Haulage purposes, it consists of the above mentioned eccentric
jaw and lever, which is attatched by means of a centre pin or stud (on which the
eccentric jaw works) to a bracket having a projecting lip which forms a groove at the
lower side of the bracket there is also attatched to the bracket a link-When put to
work, this link is hooked to the wagon or tub and the rope placed between the groove
in the bracket and the eccentric jaw, the lever end is then dropped down so that the
eccentric jaw presses the rope against the sides of the groove in the bracket.
Immediately the jaw comes in contact with the rope, the resistance of the wagon or
tuh causes the eccentric jaw to clutch the rope and so haul the wagon.
The eccentric jaw may be made of a strength equal to its requirements with a U
or ✓ groove which is best suited for any particular rope to which it may be applied.
In the accompanying Drawings Fig. 1 is an elevation of a cage with two of our
safety clutches attatched, in which the cage slides and is free of the conducting
ropes.
Fig. 2 is also an elevation of a cage with two of our safety clutches shewing the
cage when the rope or suspension chains are broken and the conducting ropes being
gripped by the clutches.
A is the lever and eccentric jaw.
BB are the slotted Brackets.
Cis the centre pin or which the eccentric jaw works.
Dis the end of the lever to which is attatched the spring and the chain for holding
the same in position, and free from the conducting ropes or guides.
EE are the conducting ropes or guides.
The same letters refer to the same points in both illustrations.
In its application for Haulage purposes Fig. 3 is a side elevation of one of our
clutches.
A is the lever and eccentric jaw.
B is the bracket on which is the projecting lip which forms the groove in which
the rope is fixed as shewn in Fig. 4 at X.
C is the centre pin which attatches the eccentric jaw and lever to the aforesaid
bracket.
D is the link which is attatched to the wagon or tub E is the rope with the eccentric
jaw clutching the same Fig. 4 is the end elevation of Fig. 3.
The same letters refer to the same points in both illustrations.
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-
The use of a lever with an eccentric jaw in combination with a grooved bracket
and centre pin, applied to grip a rope either for hauling a wagon or tub, or suspending
a cage which when put in action the lever moves downwards and causes the eccentric
jaw to press the rope against the sides of the groove in the bracket and thus firmly
grips the aforesaid conducting rope or guides as set forth in the drawings.
