I, AARON STEPHENSON, of 151 Manchester Road, Bradford, Yorkshire, Joiner; do
hereby declare the nature of this invention to be as follows:-
My invention has reference to a new construction of butt-hinge, which not only
answers the ordinary purpose of hanging a door, but, on the door being opened, such
hinge causes the door to rise for the purpose of clearing the carpet or other floor
covering, whilst the construction and method of fixing such hinges closes the door
automatically after it has been opened.
In order that my improved butt-hinge may be fully understood, I will make
reference to the accompanying sheet of drawings, wherein Fig. 1 is a top edge view
of the hinge; Fig. 2 is another view thereof, and Fig. 3 shews the application of such
hinges to a door, and Fig. 4 is plan view of same. This butt-hinge is composed
of two plates a and b, but the plates are cranked as shewn at c for the purpose of
placing the connecting pin d out of a direct line with the plates a and b. If, however,
hinges made in the above manner were fastened to a door, both top and bottom, in the
same position as shewn at e, such hinges would not accomplish the two objects sought
to be attained by my invention, namely, the rising of the door to clear the carpet,
and the closing of the door automatically; but if such hinges are attached to the door
in the manner shewn at e and f, where it will be seen that at e the plate a is attached
to the door, but at f the plate a is fastened to the door frame, the object being to throw
the pin d at different or opposite sides to the vertical edge g of the door.
By making butt-hinges with the connecting pin d off the side of the plates a and b,
and by fixing such butt-hinges so that the said pin d.in the one case is in a position
as shewn at e and in the other case in position as shewn at f, or vice versa, such doors
so hinged, on being opened, will be thrown out of plamb, or out of a vertical position,
somewhat in the manner indicated by dotted lines in Fig. 3, whereby the door is clear
of the carpet or other floor covering, and on being opened and released, the peculiarly
hinged joints will close.the door.

An Improved Butt Hinge and Method of Fixing same to Doors.
I, AARON STEPHENSON, of 151 Manchester Road, Bradford, Yorkshire, Joiner, 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 :-
My invention has reference to a 'new construction of butt-hinge, which not only
answers the ordinary purpose of hanging a door, but, on the door being opened, such
hinge closes the door automatically after it has been opened.
In order that my improved butt-hinge and the method of fixing same may be better
understood, I herein make reference to the accompanying sheet of Drawings, wherein
Fig. 1 is top edge view of the butt hinge, and Fig. 2 edge view thereof. Fig. 3
shows the application of such hinges to a door, and Fig. 4 plan view of same.
My improved butt hinge is composed of two plates a and b, but the plates are
cranked as shewn at c for the purpose of placing the connecting pin d out of a
direct line with the said plates a and b. If, however, hinges made in the above
manner were fixed to a door both top and bottom in the same relative positions as shewn
at e in Fig. 3, such hinges would not accomplish the two objects sought to be attained
by my invention, namely, the rising of a door to clear the carpet, and the automatic
closing of the door when released, but if such hinges are attached to a door in the
manner shewn at e and f' in Fig. 3, where it will be seen that at e the plate is attached
to the door A, but at the plate a is fastened to the door frame B, the object of
so fixing being to throw the hinged pin d at different or opposite sides to the vertical
..edge.g of the door A.
By making butt hinges with the connecting pin d off the side of the plates a
and b, and by fixing such butt-hinges so that the said hinged pin d in the one case
is in a position as shewn at e, and in the other case in position as shewn at f, such
doors so hinged on being opened will be raised and thrown out of plumb, or out of a
vertical position, somewhat in the manner indicated in dotted lines in Fig. 3, whereby
the door is lifted clear of the carpet or other floor covering, and on the said door
being opened and released, the peculiar hinged joints will close the door.
It will be apparent that the binged pin d of-one hinge-must be lineable with the
corresponding hinged pin of the other hinge, as shewn in Fig. 3 and again in Fig. 2,
.where it will be observed that pin d is thrown a little to the right, but instead of
making the hinges with the pin d out of vertical line, the same object can be
attained by simply twisting the butt hinge to one side,. when fixing, as will be well
understood.
Although I have described and shewn in the Drawings where two of my improved
butt-hinges are applied to a door, I would observe that one ordinary hinge may be
used in combination with one of my improved butt-hinges, as the position of the
hinged pind on one side of one hinge, as already explained, is sufficient in combination
with an ordinary hinge to lift the door and automatically close it.

page_text: In Fig. 5 I have shewn in plan one of my improved butt-hinges, as indicated by
letter C, in combination with an ordinary hinge, indicated by lotter D, whilst Fig. 6
shews the positions that such hinges occupy when the door is opened. Fig. 7 shews
another combination of a common hinge with one of my improved hinges, but in this
case the hinged pin d is carried by double cranked hinge, but instead of the cranks
being at right angles as shewn, they may be at an angle as indicated by dotted
lines h.
The peculiar characteristics of this invention will perhaps be better understood when
it is explained that if a door is hung with my improved hinges fixed both top and
bottom, as illustrated in Fig. 3, that the door will swing or move on the lines of a
double cone as seen in diagram Fig. 8, but if one of my improved hinges is attached
to the bottom of the door, and an ordinary hinge at the top of the said door, then
such door would move or swing on the lines of a single conical system, as indicated
by diagram Fig. 9.
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
Firstly. The construction of a butt-hinge where the pin on which the hinges move
is placed off one side of the line of plates such as a and b substantially as shewn and
described herein.
Secondly. The construction of butt-hinges made substantially as herein shewn and
described, and fixed to a door where the pins of the hinges are placed at opposite sides
of a vertical line, as indicated at e and fin Fig. 3.
Thirdly. The construction of butt-hinges made substantially as described and shewn
in Figs. 1 and 2, working in combination with an ordinary hinge, as herein described
and illustrated.
