Improvements in the Manufacture of Doors.
1, PHILIP SCARBOROUGH KING, of Bridge Wharf, Kingsland Road, London,
Timber Merchaut, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is the construction of doors of extreme lightness
resembling in appearance doors of much greater weight as ordinarily made.
The styles or vertical members and transverse members of the framework of the
door proper are made hollow so that in cross section they resemble tubes of
rectangular form; they are of thin material such as pine and are strengthened by
thin internal picces which may either be arranged at short distances apart and
parallel to one another or approximately so or may be diagonally arranged so that
a series of them will form a sort of zig zag; or in some cases a thin piece
of suitable material of corrugated form might be employed. The panels are
similarly constructed but so that they are thinner than the framework. Such a
door may for ornament, be furnished with mouldings made hollow so as to be light.
When a lock is required it is or may be inserted after the manner of a mortice
lock, strengthening pieces being introduced into the door to assist in supporting the
lock.
I, PHILIP SCARBOROUGH KING, of Bridge Wharf, Kingsland Road, London,
Timber Merchant, 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 :-
The object of this invention is the construction of doors of extreme lightness
resembling in appearance doors of much greater weight as ordinarily made.
The styles or vertical members and transverse members of the framework of the
door proper are made hollow so that in cross section they resemble tubes of
rectangular form; they are of thin material such as pine and are strengthened by
thin internal pieces which may either be arranged at short distances apart and
pafallel to one another or approximately so or may be diagonally arranged so that
a series of them will form a sort of zig zag; or in some cases a thin piece of
suitable material of corrugated form might be employed. The panels are similarly
constructed but so that they are thinner than the framework. Such a door may
for ornament, be furnished with mouldings made hollow so as to be light. When
a lock is required it is or may be inserted after the manner of a mortice lock,
strengthening pieces being introduced into the door to assist in supporting the
lock.

page_text: Referring to the accompanying illustrative drawings,
Fig. 1 shows a door in elevation, A. A being the styles or vertical members of
the framework, B, B the transverse members, and C, C the panels.
Fig. 2 is an edge view.
Fig. 3 is a view shewing alternative constructions of vertical and transverse
members as also a construction of the panels according to my invention as herein-
above set forth.
Fig. 4 is a vertical section in the line X Y of Fig. 1.
At A', A in Fig. 3, the styles or vertical members are made hollow so
that in cross section they resemble tubes of rectangular form of thin material
strengthened by thin internal pieces a arranged at short distances apart
and parallel to one another, these being fastened by glueing or otherwise to
the walls of the tube. In the same figure at A is represented a style
or vertical member wherein the thin internal strengthening pieces a are
arranged diagonally so als to form a sort of zig-zag, but obviously, in
lieu of these separate pieces so arranged a continuous piece or pieces bent to a
corrugated form might as hereinabove mentioned be employed, being properly
fastened of course to the walls of the rectangular tube so as to form a strong but
light style. At B, B1, B₁ the transverse tubular members are represented as being
strengthened by vertically arranged thin strengthening pieces properly fastened
to the walls of the rectangular tubes, whereas at B32 and B3 diagonally arranged
internal strengthening pieces are shewn. The hollow panels are represented as
being strengthened by horizontal internal strengthening pieces parallel to one
another but strengthening pieces arranged diagonally or otherwise might be
employed. At D, Fig. 3 I have shewn how, strengthening pieces can be inserted
to form a mortice adapted to receive a suitable lock.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
1. In the construction of doors making the frames hollow or tubular of thin
material with thin internal strengthening pieces as described.
2. In the construction of doors making the panels hollow with thin internal
strengthening pieces as described.
3. The construction of doors as hereinabove described with reference to and
illustrated in the accompanying drawings.
