IMPROVEMENTS IN LOCKS FOR DOORS
Year: 1878

page_text: LETTERS PATENT to William John Hinde, of 237, Euston Road, in the County
of Middlesex, Cabinet Manufacturer, for the Invention of "IMPROVEMENTS IN
LOCKS FOR DOORS."
Sealed the 16th May 1879, and dated the 18th November 1878.
PROVISIONAL SPECIFICATION left by the said William John Hinde at the
Office of the Commissioners of Patents on the 18th November 1878.
WILLIAM JOHN HINDE, of 237, Euston Road, in the County of Middlesex,
Cabinet Manufacturer. "IMPROVEMENTS IN LOCKS FOR DOORS."
These improvements in locks for doors consists in arranging the portion of the
lock containing the working parts so that it can slide upon the lock plate in cases
where the key or handle works from either side; in making the hole in the lock
plate slotted so as to allow of the lateral movement of the working parts holding
the key and handle to slide in relation to the lock plate; and in a variable adjust-
ment by screws or slots of the bolt and catch to suit the varying lengths required
when the part of the lock holding the working parts and the lock plate are moved
or adjusted to different positions, the object being to enable one sized lock to be
used to suit several varying sizes of the stiles of the doors, and so that the key or
the handle may always be placed where it is usual to place them in the centre of
the door stiles.
I make the portion of the lock containing the working parts to slide upon the
lock plate by attaching to the plate small guides between which the working parts

page_text: slide, and fix them where required by screws or a pin or pins; on the working case
may slide in suitable grooves in the lock plate. The adjustment of the length of
the bolt or catch may be made by having a length of screw forming the stop or
connection between the part of the bolt or catch worked by the key or handle, and
the bolt or catch holding the door in the jamb; or the adjustment may be made by
the several parts sliding in any way and holding them by suitable screws.
The
slot in the plate, when required, may be a simple opening, or it may have a piece
containing the key hole and the mortise hole of the handle shaft sliding in a
suitably prepared recess, so that the opening may not be so unsightly and be flush
with the plate.

Cabinet Manufacturer. "IMPROVEMENTS IN LOCKS FOR DOORS."
These improvements in locks for doors consist in arranging the portion of the
lock containing the working parts, so that it can slide upon the lock plate; in cases
where the key or handle works from either side in making the hole in the lock
plate slotted so as to allow of the lateral movement of the working parts holding
the key and handle to slide in relation to the lock plate; and in a variable adjust-
ment by screws or slots of the bolt and catch to suit the varying lengths required
when the part of the lock holding the working parts and the lock plate are moved
or adjusted to different positions. The object being to enable one sized lock to be
used to suit several varying sizes of the styles of the doors, and so that the key 'or
the handle or both may always be placed where it is usual to place them in the
centre of the door styles or where it may be desired. I make the portion of the
lock containing the working parts to slide upon the lock plate by attaching to the
plate small guides between which the working parts slide, and fix them where
required by screws or a pin or pins; or the working case may slide in suitable
grooves in the lock plate or in any other suitable manner.
The adjustment of the length of the bolt or catch may be made by having a
length of screw forming the stock or connection between the part of the bolt or
catch worked by the key or handle and the bolt or catch holding the door in the
jamb; or the adjustment may be made by the several parts sliding in any way and
holding them by suitable screws. The slot in the plate, when required, may be a
simple opening, or it may have a piece containing the key hole and the mortise hole
of the handle shaft sliding in a suitably prepared recess, so that the opening may
not be so unsightly and be flush with the plate.
In the Drawings, Figures 1 to 6, accompanying and forming part of this Specifi-
cation, the like letters shewing like parts, a is the plate of a lock upon which slides
the box b containing the lock mechanism for the key, key pin, and bolt connector c,
the handle pin d for the catch connector e. The bars between which the box slides
are in this case raised portions f, and a slotted portion of the box b, viz., b¹, b¹, has
set screws 62, 62, also serving as guides; in some cases these alone would be
sufficient, or any equivalent means might be employed. The catch connector and
the bolt connector are attached to the bolt g and catch h by means of the screws i,
and by means of these screws and the sliding of the box the mechanism of the
lock and the acting position of the bolt and catch are brought into the required
position, so that the key hole may be in the desired position in the style of the
door.
In place of the screws i, i, sliding bars may be employed fixed with set screws ;
but the form of the Invention shewn will be most convenient and more easy of
adjustment. If the screws are too long a portion may be cut from them.
The arrangement for the vertical play of the handle in the style of the door is
accomplished in the following manner-d is the socket in connection with the
latch to be turned; into this fits the piece j with the arm and pin ; over this is
fitted to move adjustably by the screws and slots 7 the piece m; to this is fitted the
slotted lever n, within which works the pin k; n¹ is the projecting square in
connection with which is fixed the usual handle for operating the catch of the lock;
the boss n' is shouldered and rivetted into the plate m, free play being allowed for
turning. Figure 4 shows the action of the slotted lever by the dotted lines. It
will be evident that the handle has thus a means of adjustment to fit it for the
desired position it has to occupy on the door style; and, if desired, by a slight

page_text: variation of the slots it is evident that besides the vertical adjustment a horizontal
adjustment can also be combined with it.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is,―
Firstly. The arrangement of sliding the mechanical portion of the lock in
reference to the lock plate in connection with either the key bolt or catch bolt, or
with both in combination with the screws i, i, or other equivalents, for the purposes
of adjustment of the key hole to the door style, substantially as described.
Secondly. The means of adjustment shewn and described for the handle in
connection with the lock or in any other equivalent manner, substantially as
described.
Thirdly. The arrangement of the lock plate with adjustable movement and
catches and bolt to adapt it to fit varying widths of door styles, so as to allow the
key hole to appear in any desired position in the door style with or without the
adjustment for the handle, substantially as described.
In witness whereof, I, the said William John Hinde, have hereunto set my
hand and seal, this Sixteenth day of May, in the year of our Lord One
thousand eight hundred and seventy nine.
WILLIAM JOHN HINDE. (L.S.)
