Improvements in or connected with Door Hinges, Means for Closing
Doors, and Means for Holding Doors Open.
1, LOUIS CAMILLE GORISSE, of Sains-du-Nord, (Nord), in the Republic
of France, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to cause the door when being opened to be
raised sufficiently to clear the thickness of the carpet and at the same time facilitate
the lubrication of the hinges, and to automatically close the door.
In carrying out this invention I hinge the door to the door cheek by means of
blind hinges, i.e. hinges which permit the lifting of the door. To the hinge side
of the door cheek and the respective side of the door frame are fixed respectively
a suitable distance above each other a semi-spherical socket and in the latter is
employed a spindle having semi-spherical ends. When the door is closed this
spindle inclines whilst when the door is opened it assumes a vertical position and
in doing so its upper end lifts the door the thickness of a carpet from the floor.
Upon the door cheek on the hinge side is fixed a spring which when the door has
been opened completely engages behind an abutment plate fixed upon the door
frame and retains the door in position.
When disengaging the said spring the door will close through its own weight.
During the opening of the door the pins of the wings secured to the door
will lift a little out of the wings secured to the door cheek and thus readily allow
of lubrication.

Improvements in or connected with Door Hinges, Means for Closing
Doors, and Means for Holding Doors Open.
I, LOUIS CAMILLE GORISSE, of Sains-du-Nord, (Nord), in the Republic
of France, Mechanic, 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 has for its object to provide means which cause the door, when
being opened, to rise sufficiently to clear the thickness of the carpet and when
being closed to lower onto the Hoor and thus prevent draught and at the same
time facilitate the lubrication of the hinges, and automatically close the door.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like part in the various figures, Figs. 1 & 2 being side elevations

page_text: of a door shown closed and open respectively and provided with my improvements
and Fig. 3 a plan, the full lines showing the door closed and the dotted lines
opened.
In carrying out this invention I hinge the door to the door cheek g by means
of blind hinges f,f, i.e. hinges which permit the lifting of the door. To the
hinge side of the door cheek g and the respective side of the door frame h are
secured a suitable distance above each other plates a & b having semi-spherical
sockets a¹ & 6¹ respectively and in the latter is employed a spindle c having semi-
spherical ends. When the door is closed this spindle inclines as shown in Fig. 1,
whilst when the door is opened it assumes a vertical position as shown in Fig. 2,
and in doing so its upper end lifts the door the thickness of a carpet from the
floor. Upon the plate a, on the door cheek g is hinged by a pin d', a spring d
which when the door has been opened contacts with an abutment plate e fixed upon
the door frame h.
To bring the said spring out of contact with the plate e it is turned upon its pivot
into a vertical position.
During the opening of the door the pins flift a little out of the wings f
secured to the door cheek and thus readily allow of lubrication which preserves
the hinges.
It will thus be readily understood that when opening the door the sockets a¹ & b
tend to approach each other, but being kept at a distance by the spindle c and the
door cheek being a fixture, the door will be caused to rise gradually.
When the door has been completely opened it is propped up by the socket a, a¹
and rests in such position.
spring d is placed in its horizontal position,
against the said spring and the door to be
In order to close the door the
which causes the plate e to abut
pushed back.
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-
A device for gradually lifting doors when being opened, consisting of a spindle c
mounted between two sockets a, a¹ & b, b', secured respectively upon the door cheek
and frame adapted to retain the door in position when quite open, in combination
with a movable spring d adapted to abut against a plate e secured to the door for
the purpose of closing the same, all substantially as set forth.
