I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester,
both in the County of Lancaster, and 323 High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be as
follows
This invention relates to a device which renders it possible to open doors,
windows, box lids and the like, to both sides, that is to say, to the left as well as to
the right, or both inwards and outwards.
The invention consists in fastening two bars horizontally above and below on the
frame as well as on the corresponding edges of the doors, windows or lids, and two
further bars on the window. Between these bars, levers are arranged, which
connect one end of the bars attached to the frame to the other end of the
corresponding bars on the door, and these levers are free to move at both points of
connection on pins or pivots. The bars may, if desired, be replaced by suitable
blocks or bolts. By this arrangement, two hinges are formed, the one at the left
and the other at the right, on which the doors or the like may swing. The door
either turns with one lever swinging on the pins or pivots attached to the frame, or
the door turns on the pin or pivot attached to it, and the lever remains in its
original position. Various arrangements may be employed for taking care that the
door swings on its fixed pivots, and simultaneously the lever on the pins attached to
the frame.
Assuming that the point of rotation is arranged at the top and at the bottom in
such a way that the pins attached to the frame stand at the top at the right hand,
and at the bottom at the left hand whilst the door is open; then; on the door being
closed, the pin fixed to the door at the top is brought to the left hand, and that below
to the right hand. The axis of rotation is thus always formed on each side by one
pivot attached to the frame and one pivot fixed to the door, the centre lines of
which must coincide. Hooks may be attached in this middle line on both sides of
the frame on which suitably shaped bands may rest.
If the door be opened to one side, these bands situated on this side engage
the corresponding hooks, and prevent the door turning in the opposite direction.
Further security is afforded by projections being made on the lever, which engage
with a spring action in corresponding recesses of the bars similar to those in fixed
measuring rods.
If the door be then opened in one direction, the projections which secure the door
in this direction, that is to say, those found on the larger lever arm will be
drawn out of the corresponding recesses, whilst the other projections remain in their
recesses.
When closed, the door can be secured by means of a double lock which is placed
in the centre of the door, or may be retained by two locks at the sides. It is easily
seen that the above named arrangement may be employed in doors which are to be
opened both inwards and outwards.

page_text: This improved device is suitable both for fastening doors and the like as well as
for boxes, and receptacles of all kinds.
A further improvement of the object herein before described, by means of which
a safe guidance when the door or the like is opened is obtained, consists in attaching
pins to the right and left door posts, which, with their corresponding parts fixed on
the doors or the like, resemble ordinary fish joints or bands.
The part of the pin attached to the door post by means of a flap has at the top a
pin on which planes are keyed on both sides parallel to the axis.
The part attached to the door is provided in the usual manner with a slot, with
which it may be raised over the pins, and has at one point a slot which is somewhat
broader than the pins at the part which is limited by the parallel planes.
When the door is closed, the part-attached to the door may be drawn away from
the pin by means of the slot. This takes place when the door is turned on the pin
fixed at the opposite side. On the door being turned on its pivots, these afford at
once a guide, so that the door is never lifted off the respective posts.
The arrangement may also be reversed, namely, so that the segment pins are
attached to the door and the slotted corresponding parts to the posts.

COMPLETE SPECIFICATION.
An Improved Hinge Device for Doors, Windows, Box-lids, and
the like.
A communication by JOHANN HEINRICH WEIGEL, of 27, Findelwiesenstrasse,
Nuremberg, in the Empire of Germany, Merchant.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 a device which renders it possible to open doors,
windows, lids of desks, and the like movable closing parts, to both sides, that is to
say, either to the right or to the left, or inwards or outwards.
This object is attained by revolubly attaching the door, lid or the like to one end
of each of two levers which cross one another or run parallel, the other ends of the
levers being hinged to the frame or casing which is to be clused.
Various forms of construction of this improved device are shown in the
accompanying drawings, the first of which, Figures 1 to 7, has the following
peculiarities: :-
Bars (c on the casing and 2 on the door or other closing part) are attached to
the casing a, as well as to the corresponding edges of the door, or the like b, at the
top and at the bottom. Between these bars, levers d are arranged, which connect
one end of the bar fixed to the casing to the other end of the corresponding bar on
the door or the like, and are revoluble at both points of connection by means
of pins e or the like. The bars e¹ and e² may also be replaced by suitable bolts or
swivels, or the like.
By this arrangement two axes of rotation are produced one to the left and one
to the right, on which the door, or the like, may swing. The rotation takes place
either by means of the lever d turning on the pivot attached to the casing
(Figure 5), or by the door or the like swinging on the pivot attached to the lever d,

page_text: whilst the latter remains in its normal position (Figure 6). In order to prevent the
door swinging on the pivot fixed to the lever d and simultaneously the lever d
turning on the pivot attached to the casing, various arrangements may be
provided.
In Figure 1 the points of rotation above and below are arranged diagonally, so
that one of the pivots fixed to the casing is at the top on the right hand side and the
other at the bottom on the left hand side. When the door is closed, the pivots
fixed to the door or the like are correspondingly brought at the top to the left, and
at the bottom to the right. An axis of rotation is thus formed at each side, by one
pivot fixed to the casing and one fixed to the door, the centre lines of which must
coincide.
Hooks may be arranged in these centre lines at both sides of the casing,
on which hooks suitably formed bands may rest so as to half encircle them
(Figure 7). If the door be opened to one side, the bands on this side engage
the corresponding hooks 9 (Figure 1), and prevent the turning of the door in the
opposite direction.
A further security may consist in providing projections i on the levers d
(Figures 5 and 6), which projections engage with spring action in suitable recesses k
of the bars c and c², similar to a hinged rule.
If then the door be opened in one direction, the projections which retain
the door in this direction, that is those on the larger lever arm, will be drawn
out of their corresponding recesses, whilst the other projections remain in their
recesses.
When the door is closed it may be fastened, either by means of a double lock
situated in the centre of the door, or by two locks arranged at the sides.
It is readily evident that the above described arrangement may be applied to
such doors or the like intended to be opened both inwards and outwards.
This improved device is suitable both for the closing parts of door and window
openings, and also for boxes and receptacles of all kinds.
The arrangements shown in Figures 8 to 13 are a completion of the above
described object by means of which a sure guidance is provided in opening the doors
or the like.
For this object pins or pivots are attached both to the right as well as the left
hand door posts, which pins form with their sockets m fixed to the door to all
appearance ordinary strap hinges.
The part 1, attached to the door post by means of the projection n has a pin o at
the top, on which at both sides planes parallel to the axis are formed (Figures 10
to 13). The part m attached to the door is provided with a ring or socket in the
usual manner into which the pin o engages. At one point this socket has a slot p,
which is somewhat broader than the pin o across the parallel planes.
p.
In Figures 10 and 11, the door hinge is shown with the door closed. In this
position the part m may be drawn away from the part 1 by means of the slot
This takes place when the door is turned on the pivot placed on the opposite side.
When the door is turned on the pivot, this affords at once a guide, so that the
door can never be lifted from off its door posts.
Figures 12 and 13 show the opposite positions of the parts and m when the door
is opened. The arrangement may also be reversed, namely, the segment pin may
be attached to the door and the slotted socket to the door post.
Figure 14 shows a simplified forin of the improved device, which is intended,
more particularly, for use on small cheap boxes, chests and the like. In this, in
place of two bars c¹ c² connected by means of a lever d only one lever d is employed
at each end, which on the one hand is revolubly connected with the lid band on the
other hand with the box a. The levers are here arranged diagonally opposite one
another, so that one lever d is revolubly attached to the left, and the other to the
right hand side of the box a and correspondingly the opposite ends of these levers
on the right and the left side respectively of the lid b. By the revoluble
attachment of these levers to the lid, and the box, two axes of rotation are produced

page_text: which lie through the points of attachment e of the levers. The lid may conse-
quently be opened either to the right or left side, and if necessary, may be fixed or
locked in any position by means of a lock, which may be attached to both sides.
The arrangement may, of course, as already stated at the commencement of this
Specification, be also made in such a way that both levers may be fastened on the
same side of the lid, or the box, so that in one case the rotation takes place on the
pivot attached to the box and in the other case on the pivot attached to the lid.
It is of course evident that in the device herein before described the lever may be
of any suitable shape and movably connected in any desired way with the casing or
the door or the like
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:
----
1. A hinge device for doors, windows, box lids and the like movable closing
parts, consisting in the arrangement of pivots or pins e on the casing and on the
opposite sides of the door or the like, which pivots are so connected by means of
levers d that the door or the like may swing or turn either on the pivots attached
to the door or on those attached to the casing, whereby the same may be opened to
the right or to the left, substantially as described and shown.
2. A hinge device for doors, windows, box lids and the like movable closing
parts such as described in Claim 1, in which the pins or pivots attached to the
casing and correspondingly also those attached to the door, or the like, are placed
above and below on opposite sides, diagonally to each other so that the axis
of rotation is always formed by one pin or pivot fixed to the casing and one to the
door, substantially as and for the purpose described and shown.
3. The combination with a hinge device such as described in Claims 1 and 2, of
hooks and g arranged in the axes of rotation and projections on the lever d
engaging in recesses k in the corresponding bars all substantially as and for the
purpose set forth.
4. The combination with a hinge device such as described in Claims 1 and 2 of a
slotted hinge l m o substantially as and for the purpose set forth.
