We JOHN BOARDMAN of No. 9 Paghouse Lane, Mechanic & DAVID HALSTEAD
of No. 199 Blackburn Road Manufacturer both of Haslingden in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
This invention relates to improved appliances for automatically stopping the cage
or hoist accurately to the line of the floor levels, to opening and closing the doors
protecting entrance to the "well" and preventing straining or breakage of the doors
in case of obstruction to the free swinging or opening of the latter.
The improved appliances comprise studs in connection with the well rod, and a
weighted drop catch, the studs being set or adjusted so as to operate the catch.
The gate is carried on inclined bosses on a vertical shaft and on the latter is a long
collar or boss in which is a spiral or twisted cam groove by means of which and a cam
stud or runner the gates are opened and closed. The inclined bosses permit the gate
to lift or rise on their supporting shaft.

page_text: We JOHN BOARDMAN of No. 9 Paghouse Lane, Mechanic and DAVID HALSTEAD of
No. 199 Blackburn Road Manufacturer both of Haslingden 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 :-
This invention relates to improved appliances for automatically stopping the cage or
hoist accurately to the line of the floor levels, to opening and closing the doors
protecting entrance to the "well" and preventing straining or breakage of the doors
in case of obstruction to the free swinging or opening of the latter.
The improved appliances comprise studs in connection with the well rod and a
weighted drop catch, the studs being set or adjusted so as to operate the catch.
The gate is carried on inclined bosses on a vertical shaft and on the latter is a long
collar or boss in which is a spiral or twisted cam groove by means of which and a
cam stud or runner the gates are opened and closed. The inclined bosses permit the
gate to lift or rise on their supported shaft.
Such being the nature and object of this our said invention the following is a
completo description of same reference being had to the accompanying drawings
which form part of this specification in which,
Fig. 1 is an elevation looking from back of the well or inside the hoist door half
opened.
Fig. 2. is a side elevation.
Fig. 3. is a plan view of the top of the apparatus shewing gearing &c.
The remaining figures are details or parts detached.
At 1 is a vertical well rod free to be turned and lifted in its guides 2 and long foot
socket 3. On the said rod are studs 4 one stud for each floor, the studs stand at
different angles from the well rod 1, so that by partially turning the said rod one of
the studs 4 will enter between the fingers 5-6 and when the rod is pulled down or
lifted, the stud 4 by the links 7, 8, 9 lifts the weighted end 10 of the lever 13 and
raises the door bolt 11 out of the bolt staple 12 and the door 12ª is then free to open;
the movement of the part 10 on fulcrum 10 permits the other end of bolt lever 13 to
lower the spindle 16 on which is keyed the locking boss 17, the spindle 16 passes
through the main hollow axis 16" and is made fast by the key and Mot 16" (see fig. 5)
and on the spindle 16 is fast the inclined cam bosses 18.
Meanwhile the same movement of the well rod 1 (downward pull as shewn by fig. 2)
will by the locking piece and disc 20 operate the lever 21 on its fulcrum 22 and by the
slotted link 23, and fork slide bar 23" inove the driving belt 25 from the loose pulley 26
to the fast pulley 28, the worm 29" and wheel 29 will drive the shaf tand pulley 31,
the latter through the rope 32 lifting the cage 32 and by the time the cage has
reached such position in altidude of the "well" as that the bottom of the cage is level
with the floor or landing in which stud 4 was engaged with the fingers 5-6, a pin 30
attached to the cage will have entered the cam groove 19" of the long collar 19 which
was loose on its axis 16 until descent of parts 14, 17, the latter locking 19 fast on
axis 16, the movement of the pin 30 in groove 19ª turns axis 16 and by the hinges 18ª

page_text: and to the door 12ª, the latter is swung open, the inclined surface of the boss 18
slightly raises the door that its bottom clears any slight obstruction or unequality of
floor level.
The cage having now arrived opposite the floor level its motion is next to be
arrested, which is automatically effected by reason of the stop piece 7° fixed to the side
of the cage coming in contact with the part or end of the pin 4 projecting through
the fingers 5-6, the immediate effect being, to lift the well rod 1 thereby transferring
the strap 25 to the loose pulley 26, stop the pulley 31 bringing the fingers 5-6 into
horizontal position and folding parts 7-8 to side of hoist.
It will be seen that just as the well rod 1 is pulled down or pushed up the lever 21
and arm 23 will operate the slide fork rod 23" and transfer one or other of the
straps 24-25 to the fast or driving pulley 28, the loose pulleys being made of sufficient
width to permit the requisite transfer of either belt to the fast pulley and yet permit
both straps being clear of pulley 28 when the cage is to be at rest, 24 is a plain strap,
25 is crossed to give the reverse rotation to. 28 for ascent and descent 29 is the main
driver.
The discs 33-33 are applied to the well rod 1 as stops for the top and the bottom
floor levels. Soon as the stop 7ª comes in contact with 33 the well rod 1 is lifted or
lowered, and strap transferred from fast to loose pulley, and the movement of the cage
is arrested.
The working the hoist is as follows:-
Portions of the circumference of the well rod 1, at each floor level, are painted,
thero being a different color for each floor level and stud 4. Suppose blue be for
stud 4 third floor, the well rod must be twisted until its part painted blue be opposite
a pointer or marker in the cage, and such movement will turn the pin 4 between the
fingers 5-6 on that floor. The well rod then being pulled down or lifted up, the
strap fork will be operated and the cage will ascend or descend until its stop piece 7"
reaches and slightly moves the pin 4 and thereby operates the well rod and strap fork
stopping the cage.
On reference to the detail view of well rod 1 sheet 2 it will be seen that the studs 4
are all at different angles, in relation to the said rod, so that not more than one of the
pins 4 can at any one time, be engaged with the fingers 5-6, of more than one floor
level, consequently the operating the well rod, releases the bolt of the door, and makes
fast the long collar 19, of that floor only, at which the stud 4 has been caused to
engage with the fingers 5-6. The doors, bolts, lever 13 and long collar 19 of the
other floors are not effected, the cage passes and repasses these without effecting any
change, because there is not any projecting pin 4 on such floor levels against which
the stop piece 7ª can come.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
In hoist operating mechanism, the studs, and links for operating the lever 13,
together with the locking boss 17, and long collar 19 all in combination, and operated
and as described and illustrated in the annexed drawings.
The mechanism for raising and lowering the cage as herein described and
illustrated by annexed drawings.
