PROVISIONAL SPECIFICATION.
Improvements relating to Doors for Churches, Chapels, and other
Public Places.
We, FREDERICK WILLIAM MARGETTS, of 7, Kelvin Terrace, Sydenham Hill
Road, Sydenham, in the County of Surrey, Plumber, and SARAH CHATFIELD, of
207, Lordship Lane, East Dulwich, also in the County of Surrey, Married
Woman, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide churches, chapels and other public
places with double doors so arranged that when one is open the other is always
closed, thus preventing draughts from entering the building and disturbing the
occupants.
According to this invention we attach the two doors together at right angles to
each other and pivot or hinge them to the door frame, so as to swing through an
angle of 90°. Preferably we place the doors in shoes top and bottom and pivot
these shoes to the frame and floor. The jamb of the door is curved to the shape of
an are of a circle corresponding to the swing of the doors.

COMPLETE SPECIFICATION.
Improvements relating to Doors for Churches, Chapels, and other
Public Places.
We, FREDERICK WILLIAM MARGETTS, of 14, Sternhall Lane, Peckham, in the
County of Surrey, Plumber, and SARAH CHATFIELD, of 207, Lordship Lane,
East Dulwich, also in the County of Surrey, Married Woman, 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 to provide churches, chapels, and other public
places with double doors so arranged that when one is open the other is always
closed, thus preventing draughts from entering the building and disturbing the
occupants.
According to this invention we attach the two doors together at right angles to
each other and pivot or hinge them to the door frame, so as to swing through an
angle of 90°. Preferably we place the doors in shoes top and bottom and pivot
these shoes to the frame and floor. The jamb of the door is curved to the shape of
an arc of a circle corresponding to the swing of the doors.
In the accompanying drawings
Figure 1 is a front elevation of a door frame fitted with a pair of double doors
made in accordance with this invention suitable for a bank, chapel, church, or other
public or semi-public place where swing doors are used;
Figure 2 is a plan of Figure 1;
Figure 3 is a plan of Figure 1 shewing the four doors folded back against the
door frame, and the central double quadrant piece E removed so that a wide
passage is opened;
Figures 4 to 7 shew the invention as applied to a single swing door.
Referring to Figures 1 to 3, two doors A and B are hinged to one door post C,
and are attached to each other at right angles preferably by means of catches D as

page_text: Both
shewn in Figure 1. These catches are pivoted on one door and take into staple
boxes or receptacles on the other door; a bolt or bolts may be used instead of the
catches, or any other suitable means of attachment may be employed.
doors A and B are of the same size and their outer styles work in a curved
piece E. This curved piece E is shaped to the arc of a circle whose centre is in
the door post C so that it corresponds with the path through which the doors travel
when turned on their hinges. The curved piece E is fixed close to the path of the
doors so as to be as nearly wind and draught tight as possible and its length is
slightly greater than a quadrant; therefore, when turning on their pivots, before
one of the doors has left the curved piece E, the other has entered at the further
end thereof, hence there will never be a direct passage through while the doors are
at right angles to each other, but one or other of them will always block the
passage and prevent the wind or draught from passing into the building. The
other door post C2 is similarly provided with two doors A2 and B2 and the curved
piece E is therefore made double quadrant shaped as shewn in Figure 2. The
dotted semicircular lines indicate the path of the doors. When the catches, bolts,
or other fastenings D are released, the doors A, B, A2 and B2 may be folded back
flat against the door frame into the position shewn in Figure 3 and there secured
by turns, buttons or other suitable device or devices F. The curved piece E is
fastened to the top of the door frame and to the threshold by bolts & or their
equivalents, and can be easily removed altogether when a wide passage way is
required.
Figure 4 shews an elevation and Figure 5 a plan of a single swing door A³
constructed in accordance with this invention and having two following doors B³
and B', one for each direction making three doors in all. The central door A³ is
supported by an ordinary spring hinge which will always return it to the position
shewn in Figure 5, its outer style works in the quadrant piece E as already
described with reference to Figures 1 to 3. The two following doors B³ and B
are each provided with a spring H which is wound round a spindle J in the door
post C³ shewn in elevation and plan in Figures 6 and 7. The centre door A³ is
secured to a plate K having two lugs or cars L one of which abuts against the
back of the door B3 and the other against the back of the door B as shewn in
Figure 5, or the centre door A³ is connected to the other two doors by a strip of
leather or other non-rigid connection. Thus when the door A³ is opened in the
direction of the arrow shewn in Figure 5, the door B³ will follow on, but the
door B will not move, and when the door A³ is released, both doors A³ and B3 will
return to their normal positions shewn. When the door A³ is opened in the
opposite direction, then the door B will follow up and the door B will remain
unmoved.
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
(1) In combination with a quadrant shaped piece such as E the use of two doors
rigidly or detachably secured to each other at right angles substantially as and for
the purpose hereinbefore set forth and illustrated in the accompanying drawings.
(2) In combination with a quadrant shaped piece such as E the use of a central
swing door A³ with two following doors B and B at right angles thereto, the
three doors being secured to each other by non-rigid connections, or provided with
means such as the plate K with lugs or ears L for causing one only of the doors B
or B to follow the central door A in whichever direction it may be opened, all the
doors having springs or spring hinges to return them to their normal positions
shewn in Figure 5 substantially as and for the purpose hereinbefore set forth and
illustrated in Figures 4 to 7.
(3) For swing doors the use of a single or double quadrant shaped piece such
as E for the purpose of preventing direct draughts passing in through the said
swing doors substantially as described and shewn.
