PROVISIONAL SPECIFICATION.
A New or Improved Door, and Spring Hinges applicable thereto
and to other Doors.
I, WALTER THOMAS KIRKLAND, of 274 Stratford Road, Birmingham in the
County of Warwick, Maltster, do hereby declare the nature of this invention to be
as follows:-
-
This invention relates to an adjustable door spring and hinge in combination,
by means of which, buildings such for example as hotel bars, may be readily
ventilated, the interior being kept from public view. When my invention is
applied to swing doors, the said doors may be readily opened and closed auto-
matically by the action of the spring.
My invention is particularly useful for ornamental half doors commonly used for
hotel bars and made in such a manner as to enable them to be easily adjusted to an
ordinary door frame, or removed therefrom when not required for use.
My invention consists essentially of an ornamental door and frame made about
one half or less than the usual size, the frame being provided with dowels, and
adjustable set screws which screw into screw sockets fixed to the ordinary door
frame.
The door being connected to the said frame by spring hinges constructed in the
following manner :-
I make from sheet or cast metal a double jointed hinge, that is to say a hinge
having one joint on the edge of the door and the other on the edge of the door
frame (on the opposite side) by which the door may be opened in either direction,
a metal plate being attached to the side of the door, also the door frame opposite
the said hinge which forms a bearing and acts as a lever when the door is opened
or closed.
Between the joints of each hinge, and on the pins thereof, I place a coil
spring having inserted therein two short springs at each end for the purpose of
strengthening the same.
The projecting ends of the main spring I cause to bear against the surfaces of
the hinge one on the outside plate and the other on the inside plate.
The function of the said springs is to automatically close the door to which they
are attached and to keep it in a closed position, which is effected by the projecting
ends of the spring aforesaid bearing in opposite directions and compressing the
spring.
с
Thus one set of springs on one side of the door will operate when the door is
opened in one direction and the other set when the door is opened in the opposite
direction.
My said invention is applicable for any kind of door either single or double
acting and may be modified in any detail as may be necessary to the carrying of
the same into effect.

A New or Improved Door, and Spring Hinges applicable thereto
and to other Doors.
I, WALTER THOMAS KIRKLAND of 274 Stratford Road, Birmingham, in the
County of Warwick, Maltster 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 an adjustable door spring and hinge in combination,
by means of which, buildings such for example as hotel bars may be readily
ventilated the interior being kept from public view.
When my invention is applied to swing doors the said doors may be readily
opened and closed automatically by the action of the spring.
My invention is particularly useful for ornamental half doors commonly used for
hotel bars and made in such a manner as to enable them to be easily adjusted to an
ordinary door frame, or removed therefrom when not required for use.
My invention consists essentially of an ornamental door and frame made about
one half, or less than the usual size, the frame being provided with dowels and
adjustable set screws which screw into screw sockets fixed to the ordinary door
frame.
The door being connected to the said frame by spring hinges constructed in the
following manner :-
I make from sheet or cast metal a double jointed hinge that is say a hinge
having one joint on the edge of the door and the other on the edge of the
edge of the door frame (on the opposite side) by which the door may be opened in
either direction, a metal plate being attached to the side of the door, also the door
plate opposite the said hinge which forms a bearing, and acts as a lever when the
door is opened or closed.
Between the joints of each hinge and on the pins thereof I place a coil
spring having inserted therein, two short springs at each end for the purpose of
strengthening the same.
The projecting ends of the main spring I cause to bear against the surfaces of
the hinge, one on the outside plate and the other on the inside plate.
The function of the said springs is to automatically close the door to which they
are attached and to keep it in a closed position which is effected by the projecting
ends of the spring aforesaid bearing in opposite directions and compressing the
spring.
Thus one set of springs on one side of the door will operate when the door is
opened in one direction and the other set when the door is opened in the opposite
direction.
a
My said invention is applicable for any kind of door either single or double
acting and may be modified in any detail as may be necessary to the carrying of
the same into effect.
I will describe my invention by reference to the accompanying drawings, the
same letters of reference indicating corresponding parts throughout.
Figures 1, and 2, represent respectively a front elevation and plan of my
invention, A is an ordinary door and B, the frame.
D, D, are two ornamental half swing doors and C, C, the frames, by which they
are suspended or held and are connected thereby to the ordinary door frame, B, B.
E, E, are adjusting screws for connecting or disconnecting them thereto or
therefrom, F shows one of the four dowels for holding the frames C. C. in
position.
The swing doors D. D are connected to the frames by spring hinges H. H. H. H
shewn more clearly at Figures 3. 4. and 5.

page_text: Figure 3 shows a front elevation and Figure 4 a plan and Figure 5 a side-
elevation of a spring hinge.
I, and J, are two metallic hinged plates provided with the hinged joints K',.
and K, by which they are jointed to the pins or spindles N, N.
A metallic plate L, is provided with hinged joints M, which are also jointed at-
right angles, on the pins or spindles N. N, thus connecting the hinge plate I, and .J
to each other by means of the plate L and at right angles to each other as shewn
at Figures, 4. and 5.
P, and P, are coil springs placed upon the spindles N, N, having extending
ends.
The upper end O, of the spring P, bears on one side of the plate L, and the
lower end R, of the spring P, bears on the face of the hinge plate L.
The upper end S, of the spring P³, bears on the opposite side of the plate L,.
and the lower end T, of the spring P' bears on the face of the hinge plate J,
thus keeping the plate and joint in their extended positions; a small coil spring U,
being placed inside and at each end of the springs I, and J, for the purpose of
strengthening and holding the springs firmly on the spindles.
The spring hinges are connected to the doors and frames as shewn in Figures 1,.
and 2, a sham plate Figure 6, being placed on the opposite side of the hinge
plates I, and J.
When a door is opened in the direction shewn in the dotted lines W, Figures 2,.
and 7, the hinge joint J, with the spring P2, operates, the pressure of the ends S,.
and T, against the plate L and the hinge plate J will cause the door to close
automatically.
When the door is opened in the reverse direction shewn in dotted lines X, the
hinge I, and P, will operate in a similar manner, the door will be closed
automatically by action of the spring P.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved doors and spring hinges constructed and combined substantially
as hereinbefore described and illustrated and for the purpose set forth.
2. The swing doors of the kind described which may be attached or detached.
to or from any ordinary door frame by means of the adjusting screws E, and
the dowels F, substantially as described and illustrated for the purpose set forth.
3. The combination in swing doors of the spring hinges operating together for
the purpose of closing the doors in the manner described and illustrated in the
accompanying drawings.
4. In a spring hinge of the kind described for automatically closing doors
operating substantially as described and illustrated in the accompanying drawings.
