Building or Buildings in Case of Fire.
JAMES KEEBLE of 110 Catherine Street Mill Road Cambridge Engineer
HENRY GEORGE SWORDER Dungate House Balsham Engineer do hereby declare
the nature of this invention to be as follows:-
The said apparatus consists of a drum or roller and at one end of the drum or
roller is attached a spring or springs external or internal and which are attachel
to a stud or pin in the frame of the apparatus and at the other end of the drum or
roller is attached a crank. The crank consists of a ratchet with a piston rod and
cylinder attached thereto. The piston rod and cylinder is intended to check the
speed of any person or persons descending.
•
The cylinder has a valve at both ends which draws in the air and as the valve.
closes by the reaction of the piston it causes compressed air which passes over.
piston or through small holes at ends of cylinder and thus regulates or checks the
speed of the piston according to the weight of person or persons descending. When
any person or persons have descended and alighted the said pistou stops by means
of the ratchet on the crank and when released from the weight of the person or
persons the rope which is attached to the drum or roller instantly ascends by means
of the spring or springs and is ready for any other person or persons. The rope.
webbing or wire has a band of any suitable material at one end which can be
easily adjusted to any person or persons by the waist either by themselves or with
assistance.
The apparatus can be attached to either floor ceiling or wall and the frame has a

The said apparatus is self-acting

page_text: The spring or springs for winding the drum or roller back when a person or
persons have alighted
The said apparatus consists of a drum or roller A and one end of the said drum
or roller A is attached a spring or springs B external or internal and which are
attached to a stud or pin C in the frame D of the said apparatus and the other end
of the said spring or springs B is attached to the said drum A and at the other end
of the said drum or roller is attached a crank E. The crank E consists of a
ratchet F the said ratchet F comes in contact with a paul J and which is attache l
to the said crank E. The said crauk E together with a piston rod G and
cylinder H is intended to check the speed of any persons or person descending.
The said cylinder H has a valve K at both ends which draws in air and as the said
valves K close by the reaction of the said piston it causes compressed air which
passes over the said piston or through small holes at cuds of the said cylinder and
thus regulates or checks the speed of the said piston according to the weight of the
person or persons descending.
°
When any person or persons have descended and alighted the said piston stops
by means of the said ratchet F on the said crank E and when released from the
weight of the person or persons the rope, webbing, or wire I which is attached to
the said drum or roller A instantly ascends by means of the said spring or
springs B and is ready for any other person or persons to descend.
The rope webbing or wire I has a band of any suitable material at one end
which can be easily adjusted to any person or persons by the waiste either with
assistance or by themselves. The said apparatus can be attached to either floor,
ceiling, or wall and the frame D has a roller or rollers (if required) affixed to
another connected frame to prevent the said rope webbing or wire from coming in
contact with any projection which may be on the building or buildings and which
'can be attached to any building or buildings.
