PROVISIONAL SPECIFICATION.
Improvements in the Construction, also in the Mode of Fastening or
Securing when Shut, of Sliding or other Doors.
I, HENRY CHAMPNESS, of South Street, Bishop's Stortford, Herts. Builder
and Contractor do hereby declare the nature of this invention to be as follows:-
This claim relates to certain improvements in the construction also in the
fastening of sliding or other doors.
These improvements consist essentially in so hanging a shutter as to cover the
top or open half of door, by cords and weights the said cords passing over pullies,
and the said weights sliding in caseings fixed to outside of door.
1 also claim the mode of fastening or securing sliding doors by forming a catch
or pall on bottom of door to engage with or catch against, a stud fixed in sill, or
ground, this catch or pall being raised and lowered by a suitable handle or lever
affixed to upper part of door, by means of a connecting rod or otherwise.
In constructing these doors I form an opening in the top half thereof in which I
insert an iron frame or grating of suitable form, consisting preferably of iron bars
this grating can be either fixed or made to open.
I cover this opening by a rising and falling shutter, arranged to slide between
suitable caseings fixed to outside of door and balanced by suitable weights within
the said caseings by means of cords passing over pullies secured to top part of door
or caseings as may be most convenient.
1 also provide a lock of suitable form which being fixed to upper part of door, in
a convenient position on turning the key the bolt thereof engages with a projection
on, or enters an indent in, the connecting rod or other part of mechanism, preventing
the catch being raised and so secures the door.
In certain cases when required I cause this lock to also fasten the rising and
falling shutter, either when shut, when open, or in two or more positions inter-
mediate. This 1 accomplish by prolonging the bolt of said lock so that on turning
the key and so shooting the bolt it may enter one of a series of holes or slots in a
plate affixed to the stile of the shutter.

COMPLETE SPECIFICATION.
Improvements in the Construction, also in the Mode of Fastening or
Securing when Shut, of Sliding or other Doors.
HENRY CHAMPNESS, South Street, Bishop's Stortford Herts. Builder and
Contractor 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 claim relates to certain improvements in the construction, also in the
fastening or securing when shut of sliding or other doors.
These improvements consist essentially in so hanging a shutter as to cover the
top, or open, half of door, by cords and weights, the said cords passing over pullies
and the said weights sliding in caseings fixed to outside of door.
I also claim the mode of fastening or securing sliding doors by forming a catch
or pall D on bottom of door to engage with, or catch against a stud E fixed in sill
or ground; this catch or pall being raised and lowered by a suitable handle or
lever F affixed to upper part of door, by means of a connecting rod G or
otherwise.

page_text: In constructing these doors 1. form an opening in the top half thereof in which I
insert an iron frame or grating A of suitable form, consisting preferably of iron
bars this grating can be either fixed or moveable. I cover this opening by a rising
and falling shutter B arranged to slide between suitable caseings C fixed to outside
of door and balanced by suitable weights sliding within the said caseings by means
of cords passing over pullies secured to the top part of door or caseings as may be
most convenient.
I also provide a lock H of suitable form which being fixed to upper part of door
in a convenient position on turning the key the bolt thereof engages with a projection
on, or enters an indent in the connecting rod G or other part of mechanism
preventing the catch D being raised and so secure the door.
In certain cases,
when required, I cause this lock to also fasten the rising and falling shutter either
when shut, when open, or in one or more positions intermediate. This I accomplish
by prolonging the bolt J of said lock so that on turning the key and so shooting
the bolt it may enter one of a series of holes or slots formed in a plate affixed to the
stile of shutter B.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The formation and use of a rising and falling shutter to close the opening
formed in upper part of door.
2. The formation of casings to the outside of door, these casings forming guides
to the said rising and falling shutter, and also for the counterbalance weights.
3. The fastening or securing of sliding or other doors by means of a pall actuated
by a lever substantially as described.
4. The adaptation of a lock to prevent the lever being raised and so securing the
door.
5. Causing the said lock to also fasten the said shutter substantially as described.
Dated this Fourth day of February 1892.
