Year: 1874

page_text: LETTERS PATENT to Benjamin Turner, of Bartholomew Close, in the
City of London, Engineer, for the Invention of "IMPROVEMENTS IN
DOOR HINGES."
Sealed the 5th December 1874, and dated the 10th June 1874.
PROVISIONAL SPECIFICATION left by the said Benjamin Turner at the
Office of the Commissioners of Patents, with his Petition, on the
10th June 1874.
I, BENJAMIN TURNER, of Bartholomew Close, in the City of London, -
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN DOOR HINGES," to be as follows:-
This Invention relates to the hinges upon which doors are hung, and
has for its objects improved methods of constructing and arranging such
hinges where they are attached to the door, so that if the door sinks or
falls so as not to properly fit the door frame when closed, it can be
readily readjusted to its proper position without removing it from its
hinges or otherwise disturbing it.

page_text: My improvements are applicable more especially to doors in which
the hinges consist of pins fixed at the top and bottom respectively of the
door frame, upon which pins are fitted and work suitable sockets
attached to the door itself, and my improvements consist in arranging
one or both of these sockets upon a frame or bracket made in two parts;
one of which fits or slides upon the other, one of such parts being firmly
screwed or fixed to the door frame, and the other part having formed
upon or attached to it the socket in which the pin attached to the door
frame works.
The two parts described are connected together by means of a
sufficiently strong screw, working through a projection formed upon or
attached to one part of the socket frame, and also through a corrc-
sponding bracket formed upon or attached to the other part of the
socket frame, in such manner that when the screw is turned the two
parts are drawn together, the one carrying the door sliding upon the one
carrying the socket, and the door can thus be raised or adjusted exactly
as required. I prefer to make the bracket and screw so that they are
concealed within the thickness of the door, but I make an opening
through the thickness of the part attached to the door opposite to the
head of the screw, so that the latter may be turned round as desired,
preferably by means of holes formed round the circumference of the
head of the screw, into which holes a lever can be inserted. And I
make a lock nut upon the screw having similar holes for a lever in order
that it can be worked through the same opening in the bracket, so that
when the door has been adjusted exactly to its right position the lock
nut can be tightened and the screw is thus prevented from again altering
its position until required.
My improved apparatus may be applied to any form of hinge fitted
either to the top or bottom of the door or to both, and it may be applied
<to any form of door or gate where it is desired that the door should be a
adjustable so as always to close properly.
Instead of the arrangement above described the socket may be fitted
to the door frame, and the pin to the door.

filed by the said Benjamin Turner in the Great Seal Patent Office on
the 10th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
TURNER, of Bartholomew Close, in the City of London, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Benjamin Turner, Her special licence
that I, the said Benjamin Turner, my executors, administrators, and
assigns, or such others as I, the said Benjamin Turner, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for " IMPROVEMENTS IN
DOOR HINGES," upon the condition (amongst others) that I, the said.
Benjamin Turner, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Benjamin Turner, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and the accompanying Drawing (that is to
say):
:-
My Invention relates to improvements in the hinges upon which
doors are hung in the usual way, and it is especially applicable to doors in
which the hinges consist of pins fixed at the top and bottom of the floor
.

page_text: frame, upon which pins suitable sockets are fitted and work, such
sockets being attached to the door itself.
My improvements consist in arranging one or both of these sockets
upon a frame or bracket made in two parts; one of which parts fits into
and slides upon the other, one of them being firmly screwed or fixed to
the door frame, and the other having formed upon or attached to it the
socket in which the pin attached to the door frame works.
The two parts described are connected together by a sufficiently strong
screw, which works through a projection formed upon or attached to one
part of the socket frame, and also through a corresponding bracket
formed upon or attached to the other part of the socket frame, in such
manner that when the screw is turned the two parts are drawn together,
the one attached to the door sliding longitudinally in or upon the one
carrying the socket, and the door can thus be raised or adjusted exactly
as and when required, so that if its outer edge sinks or falls towards the
floor so as not to properly fit the door frame when closed, its upper part
can be drawn nearer to the side of the door frame which carries the
hinge; and this adjustment can be effected without removing the door
from its hinges or otherwise disturbing it. I prefer to make the bracket
and screw so that they fit into and are concealed within the thickness of
the door, but I make an opening through that part of the hinge which
is attached to the door opposite to the head of the screw already
described, so that the screw may be turned round when requisite,
preferably by means of holes formed round the circumference of its head,
into which holes the end of a bar or lever can be inserted. I make a
"lock" nut working upon the screw and having similar holes for the
insertion of a lever, which can be worked through the same opening in
the bracket already described, so that when the door has been adjusted
exactly to its right position the lock nut can be tightened, and the screw
is thus prevented from again altering its position until further readjust-
mont in meanined

•
a is a bracket or plate fixed to the frame of the doorway and carrying
the pin upon which the socket c of the other part of the hinge turns.
The pin 6 can be withdrawn from or replaced in the socket c by turning
the screw d in order to remove or replace the door. The socket c is
carried by the plate e which fits into grooves or guides formed in the
corresponding bracket or plate f which is fitted into an opening or
mortice in the edge of the door and screwed firmly into its place. The
plate e and socket c can be forced in or out of the plate f by means of
the screw which works through the fixed block or nut / upon the
plate f, and is attached to a corresponding projection i upon the plate e.
The screw can be turned round by a lever inserted into holes in its
head through an opening k in the plate f, and it can be fixed and
prevented from altering its position when adjusted by the lock nut 7.
The operation of the hinge is as follows:-The plate a being fixed to
the door frame, and the pin 6 being withdrawn by turning the screw d,
the plate, which is fixed to the door and carries the sliding plate e and
socket c is adjusted to its position, and the pin b is brought down into
the socket c by means of the screw d. The edge of the door to which
the plate fis screwed can then be brought nearer to or further from the
pin by means of the screw g, which causes the plate f to slide upon the
plate e. When adjusted the screw is fixed by the lock nut 7.
The hinge may be applied either to the top or bottom of the door or
to both, and it may be applied to any form of door where it is desired
that the door should be adjustable, so as always to close properly.
Instead of the arrangement described the socket may be fitted to the
door frame, and the pin to the door.
Having now described my Invention and the manner in which it is
to be performed, I claim, the construction of door hinges in which the
part of the hinge attached to the door or to the door frame consists of
two pieces; one sliding in or upon the other, one of such pieces being
attached to the door or door frame, and the other of such pieces carrying
the pin or socket of the hinge, and the two pieces being adjusted and
fixed in their proper relative position by a screw and lock nut,
