Improvements in or relating to Door-hinges.
A communication from abroad by HERMANN FAULHABER of Hall, Swabia, in the
Kingdom of Würtemberg, Clergyman.
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 :-
In swing doors, as well as in cupboard or wardrobe doors (Spindthüren) and the
like, pivots are frequently employed in place of hinges for the sake of simplicity.
When these are simply fastened in the doors, the inconvenience arises that the
doors cannot be taken out without difficulty, or perhaps not at all, thus, for
instance, in the case of cupboard doors, which require to be sometimes removed
for the purpose of being cleaned or for the insertion of new panes of glass, it is
necessary to take the cupboard partially to pieces.
By this invention, however, the door is provided with a peculiar device, com-
prising a pivot mounted on a slide or foot plate which is slid into and secured to
the door by means of screws.
On the accompanying drawings
:-
Figure 1 represents a door in which the pivot is inserted from behind,
Figure 2 represents a door in which the pin is inserted sideways.
Figures 3, 4 and 5 show, in vertical section, plan and side elevation respectively,
the devices adapted for the door shown in Figure 1.
Figures 6 to 8 inclusive represent the devices adapted for the door shown in
Figure 2.
Figures 9 to 12 inclusive show a door and the device with a modification of form
adapted for those cases in which the pivot is not inserted in the door but in the
doorway frame.
Referring to Figures 1, 3, 4 and 5, the angle piece A. is let into the door T¹ and
secured therein by means of the screws a.
The angle piece B which carries the pivot C is inserted into the angle piece A in
such a way, that the horizontal arm of the former enters a slot situated in the
corresponding arm of the latter, and the vertical arm of the angle piece B is let
in the corresponding arm of the angle piece A. The slot above named has a
dovetail shape.
The vertical arm of the angle piece B is secured in the said recess by means of
the screws b. The vertical parts of the angle pieces A and B are rounded off to
allow the turning of the door. The pin C is received in a socket attached to the
doorway framing in any suitable manner. In the door shown in Figure 2, the
plate A', (Figures 6, 7 and 8) bent into an angular form, is secured to the side in
the door T. In the upper part thereof a dovetail shaped slot is situated, in which
the horizontal arm of the angle picce B', carrying the pivot C, is inserted, whilst
the vertical arm is countersunk in the vertical part of the plate A' and is held fast
therein by means of the screws b'. The angle-shaped plate A' is held firmly in the
door by means of the wood screws a'. The lower pivot can be arranged in a similar
manner to the upper one, or in any other suitable way. In order to remove the
door from out of the door casing, is only necessary to unscrew the screws bb
or . In the arrangement shown in Figure 1, the door can then be drawn out in
the direction of its plane, and in that shown in Figure 2 it can be drawn out
vertically to its plane.

page_text: In Figures 9 to 12 inclusive, a plate A' is inserted in the door frame, and held
firm therein by means of screws a².
In the plate A³ a recess is formed, in which the foot plate B², carrying the
pivot C, is inserted in such a way that it engages at one end in the dovetail-shaped
slot shown in the drawing and further is connected with the plate A by means of
the screw In the door T³, a plate D2 is inserted and secured therein by means
of screws 2. If the door is to be taken off its hinges, it is first opened and the
screws removed. The door is then pushed endways, so that the foot plate 13²
with the guide pivot C moves in the direction of the arrow, Figure 12, and is
released from the groove in the plate A². For this purpose the groove is corre-
spondingly longer than the foot plate B carrying the pivot, being preferably
tapered as shown.
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 door hinge comprising a pivot C mounted on an angle piece or slide B or B¹
one arm of which can be slid in or out of a dovetailed slot or groove of the
horizontal arm of the angle piece A. or A', whereby the door can be readily mounted
in or removed from its position and the other arm attached to the vertical arm of
the said angle piece, whilst the angular plate supporting the slide B or B¹ is
fastened to the door by means of screws.
2. A hinge for doors having the combination of the foot-plate or slide B'
carrying the pivot and the plate A secured to the doorway frame by screws, the
said slide B being adapted to be inserted in or removed from a groove or
dovetailed slot in the plate A2, substantially as and for the purpose described.
Dated this 24th day of November 1890.
