PROVISIONAL SPECIFICATION.
Improvements in connection with Locks.
I, WILLIAM JOHN HOLMAN of 124 Raymouth Road, Rotherhithe, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to the boxes or box staples or equivalents of rim and other
locks and the like, and although I shall in this specification mention my invention
as used in connection with rim locks I wish it to be understood that my invention
is capable of modification for use with other than rim locks. The ordinary box or
box staple consists of three rims with a front plate, the whole being attached to the
jamb of the door and the tongue or catch of the lock strikes against the edge of
this front plate and is forced back by it and after having passed the edge, the
tongue rebounds behind the plate and thus keeps the door closed. Now owing to
the edge of the plate being fixed and not "giving" when the latch strikes it, it
causes much noise and vibration when the door is being shut, the door often having
to be pulled or pushed several times before it can be closed. In order to obviate
this defect I substitute for the box or the like the following arrangement. To a
metal plate of greater length than breadth (which I shall hereinafter refer to as the
bottom plate) I attach three rims standing above its surface. One of these rims is
near the upper end of the plate and the other near the bottom end and the third
plate rim extends from one edge of one of the narrow rims to the corresponding edge
of the other of them. A pivot passes through the upper rim and another through
the bottom rim and on these works a plate extending from the upper to the bottom
rim. Underneath this plate is a spring which keeps it on an angle so that the lower
edge of the plate is nearer the door than the upper edge of it. This angle plate is
kept from springing out of its normally sloping position by a stop a little to the
side of each pivot. It can therefore be moved in one direction, but not in the other.
The stops are so placed that when in its normal position the spring keeps the lower
edge of the angle plate sufficiently above the bottom plate to allow the catch or
tongue to pass between the bottom plate and the lower edge of the angle plate. In
use the bottom plate is fastened to the door jamb in the place usually occupied by
the ordinary box or box staple. When the door is pulled or pushed for the
purpose of closing it, the projecting end of the tongue or catch strikes against the
lower edge of the slanting or angle plate, and the spring allowing this. plate to
"give" permits the tongue or catch to pass it and rebound behind it. Owing
therefore to the angle plate offering little resistance to the end of the lock catch or
tongue, the door closes much more silently than is the case where the tongue strikes
against the unyielding edge of the front plate of the ordinary box or box staple.
My improved appliance may be of cast or wrought metal, and extra bottom plates
may be provided to keep it at various heights above the door jamb. The general
idea is, as already mentioned applicable, with obvious modifications for use with any
kind of lock or the like.

page_text: 1, WILLIAM JOHN HOLMAN of 124, Raymouth Road, Rotherhithe, 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 :-
My invention relates to the boxes or box staples or equivalents of rim and other
locks and the like, and although I shall in this specification mention my invention
as used in connection with rim locks I wish it to be understood that my invention
is capable of modification for use with other than rim locks. The ordinary box or
box staple consists of three rims with a front plate, the whole being attached to the
jamb of the door and the tongue or catch of the lock strikes against the edge of
this front plate and is forced back by it and after having passed the edge, the

the edge of the plate being fixed and not "giving" when the latch strikes it, it
causes much noise and vibration when the door is being shut, the door often having
to be pulled or pushed several times before it can be closed. In order to
obviate this defect I substitute for the front box staple the following arrangement:
I construct the box with a yielding striking plate so that when the tongue of the
lock comes in contact with it, it will "give" and allow the tongue to pass, after
which a spring underneath it causes it to resume its normal position and keep the
tongue in plate.
In order to more clearly explain my invention I make reference to
accompanying sheet of drawings in which
Figs. 1, 2, and 3, are views of the component parts of the box.
the
Fig. 4 is a cross section through the complete box Fig. 5 a side view and Fig. 6,
a front view of the complete box.
Similar letters indicate the same parts.
a is a casting similar to an ordinary box staple; the front b however is not so
wide as the front of the ordinary box. The ears c are for fastening the staple to
the door jamb. These ears would be placed as shown by dotted lines in Fig. 5,
when the box is used with mortice locks. The top and bottom of the casting is
thickened as at d, this thickened part sloping from front to back as shown in Fig. 4.
A hole e is made at the bottom and a similar one at the top of a. f is the striking

plate, having holes at g. h is a pin round which is wrapped the spiral spring i.
assembling the parts together the plate is placed within a so that its upper and
lower ends rest against the sloping thickened part already mentioned. The pin h
is then put through one of the holes e and g: the spring i is threaded on the pin,
and the latter passed through the other holes g and e. It will be obvious that
when the tongue of the lock strikes the edge j of the plate f, f will be pressed in
the direction of the arrow shown in Fig. 4, and allow the tongue to pass, after
which it will be returned by the spring i to its normal position resting in contact
with the sloping part d. The box might be built up of various pieces instead of
cast in one piece, and any other kind of spring than a spiral one could be used
When the box is used for mortice locks an opening must be cut in the jamb so that
the tongue can have access to the striking plate f
I do not of course restrict myself to the precise shape, configuration, relative
proportions or disposition of parts described in the above specification or exemplified
in the accompanying drawing as any or all of them may be considerably varied
without departing from the spirit of my invention.

page_text: 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. A box staple for locks, the said staple having a hinged inclined striking plate
which allows the tongue of the lock to pass it and is then returned to its normal
position by a suitable spring, the whole substantially as described in the above
specification and exemplified in the accompanying drawings.
2. Constructing box staples for locks with a yielding striking plate or flap to
facilitate the passage of the tongue on closing the door and so obviating concussion
to the door and its surroundings, the whole substantially as described in the above
specification and exemplified in the accompanying drawings.
