I, ALBERT HENRY ADCOCK, of Crown Works, Conybere Street, in the City
of Birmingham, Brassfounder, do hereby declare the nature of this invention to be
as follows:-
:-
This invention has reference to the manner in which I construct and arrange
fastenings and fittings for the same for securing doors, drawers, and for like
purposes, whereby I am enabled to readily open and close the door, drawer or
other article to which it may be attached by lifting and lowering or sliding the
handle or manipulating knob provided upon the door or other furniture for this
purpose.
In carrying my invention into effect when constructing my fastening as a latch
or catch for attachment to any ordinary door, I mount a handle or lever within my
lock case in such a manner that one portion projects on each side of the door free
to work up and down upon a pivot or pin carried on the reverse side of the door or
drawer to which the latch is fixed. I make the handle or lever adjustable for
different thickness of wood by means of a long screwed collar or socket which
unites together the two handles or knobs placed on either side of the door.
I prefer to form the handle ends of the levers so that they may be readily
manipulated by hand and the act of lifting or pushing either side for the purpose
of opening or closing the door made to draw back the bolt or catch from the
staple or plate fixed on the door frame. Within my lock case I place a sliding
bolt or bolts having preferably tail ends around or against which a spring or
springs work so as to keep the door always fastened, and upon the bolt I cast
or form one or more projections against which a follower may press or to which
it may be secured. I place the follower upon a pivot within the case and 1 form
it of such a shape that one end has a projecting tongue for the hand lever to
lift or lower while the other draws back the bolt and thus unfastens the door.
vary the shape and arrangement of this follower to suit the form of handle
and size and strength of the lock to which it is to be applied, and I sometimes
provide tumblers or levers within the case so as to enable an ordinary key to
be used when it is desired to fasten or further secure the door. In order to
secure the bolt in such a manner as to prevent its fastening the door, I employ a
pin or catch piece which I cause to engage with the follower or bolt so as to
prevent its movement within the case.
I sometimes construct my handles so that a pull and push, a sliding, or a slight
turning motion instead of a lifting and lowering motion may release the bolt.
I modify the shape and configuration of my handle and fastening, together with
the locking or catching portion to suit the cabinet, drawer, door or other frame to
which it is to be applied.

Improvements in Fastenings for Doors and for like purposes.
I, ALBERT HENRY ADCOCK, of Crown Works, Conybera Street, in the City
of Birmingham, Brassfounder, 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 has reférence to the manner in which I construct and arrange
fastenings and fittings for the same for securing doors, drawers, and for like
purposes, whereby I'am enabled to readily open and close the door, drawer or
other article to which it may be attached by lifting and lowering or sliding the
handle or manipulating khob; provided upon the door or other furniture for this
purpose!
In order that my invention and the method of 'carrying the same into effect may
be the more readily understood, I append hereunto one sheet of explanatory
drawings to be hereinafter referred to:
Figure 1 'represents my improved fastening and fittings pertaining thereto; when
arranged as a² locking latch or catch for securing doors, drawers, or for like
purposes.
Figure 2-is a sectional view of the lock casing with the front or cover plate and
also the operating lever or handle:removed:
Figure 3 represents my improved fastener, without locking action or mechanism:
Figures 4 and 5 illustrate a modified form of the catch or bolt operating
action.
Figure 6 illustrates the method of adjusting the handle or lever to suit 'doors of
varying thickness.
Figure 7 represents a modified form of operating handle or lever.
In carrying my invention into effect: I 'construct my fastening as a latch' or catch
preferably as shown with a locking action by the general view Figure 1, and
without a locking action at Figure. 3, for attachment to any ordinary door.
I'mount a handle or lever such as A' Figure 1 within my 'lock' case in such a
manner that one portion projects on each side of the door free to work up and
down upon a pivot or pin a, carried on the reverse side of the door or drawer
to which the latch is fixed. I make the handle or lever adjustable for different
thickness of wood by means of a long screwed collar or socket a², Figures 1
and 6 which unites together the two handles or knobs placed on either side of
the door. I prefer to form the handle ends of the levers so that they may be
readily manipulated by hand, and the act of pulling or lifting the handle on the
side indicated by the word "Pull" Figure 1, or pushing the handle on the other
side for the purpose of opening or closing the door, draws back the bolt or catch
from the staple or plate B fixed on the door frame. Within my lock case I
place a sliding bolt or bolts having preferably tail ends as at C Figures 2 and 4,
around or against which a spring or springs work so as to keep the door 'always
fastened, and upon the bolt I cast or form one or more projections against which
a follower such as D Figures 2 and 4 may press or to which it may be secured.
I place the follower upon a pivot d, within the case and I form it of such a shape
that one end has a projecting tongue d for the hand lever to lift or lower, while
the other end draws back the bolt and thus unfastens the door. I vary the shape
and arrangement of this follower to suit the form of handle and size and strength
of the lock to which it is to be applied, and I sometimes provide tumblers or levers
within the case as shown at Figure 2 so as to enable an ordinary key as E Figure 1
to be used when it is desired to fasten or further secure the door. In order to
secure the bolt in such a manner as to keep the door closed but without operating
the locking action, or where such action is unprovided I employ a pin or catch

page_text: piece F Figures 2 and 3, which I cause to engage with the follower or bolt so as:
to prevent its movement within the case.
I sometimes construct my handles so that a sliding action, or a slight turning
motion, instead of a lifting and lowering motion may release the bolt. Figures 4-
and 5 illustrate the arrangement of the bolt releasing action or mechanism which
I preferably employ when desiring to manipulate my improved fastening by means.
of a circular or turning motion of the handle or lever. The projecting tongue d',
of the follower D is raised or turned about the follower pin d, by the tumbler or
cam piece G screwed or otherwise secured upon the operating lever or handle, at
the position 9 Figure 7. Thus when the handle is turned or slightly revolved the
projecting pin 9 of the tumbler or cam piece G raises the tongue d¹ of the
follower.D, which withdraws the bolt from the staple or plate fixed on the door
frame. The ends of the lever may be fitted with a circular knob on the one side,.
and a handle upon the other, as shown at Figure 7, or both sides or ends of the
lever may be fitted with similar or dissimilar handles or terminals of any desired.
configuration.
I modify the shape and configuration of my improved fastenings, together with
the locking or catching portion to suit the cabinet, drawer, door or other frame.
to which it is to be applied, without departing from the essential features of my
invention.
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 :-
1. An improved fastening for doors and for like purposes, having a bolt or
sliding catch for engaging with a staple or like part, which is withdrawn for
releasing or opening the door by means of a follower operated by an adjustable
lever, substantially as hereinbefore described and as illustrated in the accompanying
drawings.
2. The construction of an improved fastening having an adjustable lever such
as A, spring bolt or catch C and follower D, with locking action or mechanism,
substantially as and for the purposes herein before described and as illustrated in
Figures 1 and 2 of the accompanying drawings.
3. The construction of an improved fastening having an adjustable lever for
operating the follower of a spring bolt, and a pin or catch piece such as F, substan--
tially as and for the purposes hereinbefore described and as illustrated in Figures 2.
and 3 of the accompanying drawings.
4. The construction of an improved fastening having an adjustable lever with
tumbler or catch piece for manipulating by a circular motion, the follower of a.
spring bolt or catch substantially as and for the purposes hereinbefore. described.
and as illustrated in Figures 4 and 5 of the accompanying drawings.
