I, GEORGE FREDERICK NEWMAN of the firm of William Newman and Sons, of
Hospital Street Birmingham, in the County of Warwick, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
Lock and latch staples, or the striking plates of locks and latches, as ordinarily
constructed, are made fixed, and form only abutments, against which the bevil end of
a latch or lock bolt strikes, on the closing of a door.
According to my invention, the striking plate is made movable; that is, it is
caused to retire rearwards, or turned aside, on the latch or sliding bolt of a lock or
latch striking it.
By thus making the striking plate movable, the latch bolt. or the fastening bolt, as
the case may be, remains quiescent, on coming in contact with the striking plate of a
staple; so that the fastening is effected solely by the striker plate, coming at the back
of the fastening latch or bolt.
My new or improved striking plate, is particularly adapted to doors provided with
pneumatic air checks and springs, in consequence of the moving force of a door, at
the point of closing, being insufficient for the pressing back of the latch bolt, for
fastening; and the consequence is, that doors provided with such expedients, have to
remain unfastened, when closed or nearly so.
I will describe my invention in connection with an ordinary reversible box staple.
The frame of the staple consists essentially of an open sided box, with gapped or
cut away parts on its two opposite sides, corresponding to the breadth, and part to be
struck by the latch of a lock.
Jointed, and hanging from the extreme top inside part of the frame of the said
staple, is an arın or striker plate, of a breadth a little less than the breadth of the
staple, and with its opposite front edges, bevilled or chamfered off, at parts which
come opposite, or are presented to the side gaps as aforesaid; so that on the door
closing, the fastener or fastening bolt, strikes the striking plate at the part presented
through the side gap, and by the door's forward motion, the striker plate or depending

page_text: pivoted arm is moved aside, until the bolt has passed it, when the said striker plate
resumes its normal position, by gravity or by its own weight, and thereby fastening
and securing the fastener bolt of a lock or latch behind it.
When a staple is required to be used as an ordinary staple, the striker plate is
made a fixture, by passing a peg or the like, through holes in the frame, and striker
plate respectively.
Instead of the striker plate swinging from a fulcrum near its top end, I make the
striker plate in the form of a bolt, which is made to move up inclined guides, on being
struck by a door, and on the door being fully closed, the said striker plate resumes its
normal position, by sliding down again.
Or the striker may be made to work horizontally, with a slot in its middle, wherein
a flat or other spring is disposed, and secured to the fixed framing, and with its free
ends, acting upon the striker plate. In each case, the staples are reversible, for the
fitting of it, to a right or left handed door.

I, GEORGE FREDERICK NEWMAN of the firm of William Newman and Sons of
Hospital Street, Birmingham, in the County of Warwick, Manufacturer, 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:-
Lock and latch staples, or the striking plates of locks and latches, as ordinarily
constructed, are made fixed, and form only abutments, against which, the bevel end of
a latch or lock bolt, strikes, on the closing of a door.
According to my invention, the striking plate is made movable; that is, it is caused
to retire rearwards, or turned aside, on the latch or sliding bolt of a lock or latch
striking it.
By thus making the striking plate movable, the latch bolt or the fastening bolt, as
the case may be, remains quiescent, on coming in contact with the striking plate of a
staple; so that the fastening is effected solely, by the striker plate, coming at the back
of the fastening latch or bolt.
My new or improved striking plate, is particularly adapted to doors, provided with
pneumatic air checks and springs, in consequence of the moving force of a door, at
the closing point, being insufficient, to press back the latch bolt, for fastening, and
the consequence is, that doors provided with such closing and checking expedients,
frequently remain unfastened.
In describing my invention in connection with a reversible box staple, the frame of
the staple, consists essentially of an open sided box, with gapped or cut away parts
on its two opposite sides, corresponding to the breadth, and part to be struck by the
latch of a lock.
Jointed, and hanging from the extreme top inside part, of the frame of the said
staple, is an arm or striker plate of a breadth a little less than the breadth of the
staple, and with its opposite front edges, bevelled or chamfered off, at parts, which
come opposite, or are presented to the side gaps as aforesaid; so that on the door
closing, the fastener or fastening bolt, strikes the striking plate at the part presented
through the side gap, and by the door's forward motion, the striker plate or depending
pivoted arm, is moved aside, until the bolt has passed it, when the said striker plate
resumes its normal position, by gravity, or by its own weight, and thereby fastens or
secures the fastener bolt of a lock or latch, behind it.
When a staple is required to be used as an ordinary one, the striker plate, is made
a fixture, by passing a peg, or the like, through holes in the frame, and striker plate,
respectively.
Instead of the striker plate, swinging from a fulcrum, near its top end, 1 make
the striking plate, in the form of a bolt, moving either horizontally, vertically, or
inclined.
I will now proceed to describe with reference to the accompanying drawings, the
manner in which the same is to be performed.

page_text: Figure 1 represents in front elevation, a reversible box staple, and yielding striking
plate, constructed according to my invention. Figure 2 represents a like view as
figure 1, but with the front portion of the staple part, broken away, in order to better
exhibit the shape of the striking plate, and the joint centre from which it is hung.
Figure 3, represents a side elevation of figure 1, and figure 4 is a like view as
figure 3, but with the joint part of the said staple plate, shown in section.
Figure 5 is a transverse section on the dotted lines A B figure 2.
Figure 6 is a like view as figure 5, but showing the position of the striking plate,
when struck by the bevel end of a latch or bolt.
Figure 7 shows my invention, in connection with a lock, and with the latch bolt of
the said lock just in the act of forcing aside the striking plate. Figure 8 represents
a horizontal section of the same.
Figure 9 shows in front elevation, the latch bolt of the lock, behind the said
striking plate.
Figure 10 is a horizontal section of the said figure 9.
The same letters of reference, indicate corresponding parts in figures 1 to 10 both
inclusive.
a is an open sided box staple, with opposite side gaps a², whereby the said box staple
admits of being applied either to a right or left handed door.
b is a yielding striking plate, with front bevel edges, and which said plate, is hung
from the joint pin c, passing through the upper end of the box staple a.
a³ are screw holes, through which screws pass, in affixing the appliance to a door
frame, which is marked d.
The lock is marked e, and the door f, whilst the latch bolt of the lock is
marked e³.
On a door closing, the latch bolt of the lock, passes through one or other of the
gaps as, and strikes one of the bevels 62, of the hanging striking plate b, which
normally hangs with the bevels upon its front side, coming opposite the gaps; so that
on the striking plate being struck as aforesaid, it moves aside, and allows the latch
bolt to come at the back of it, as represented in figures 9 and 10.
When the staple is required to be used as an ordinary one, a ping is passed through
a hole in plate a, and striking plate 6 respectively, so as to make the said striking plate
a fixture.
Figure 11 represents another form of my invention, in which the striking plate is
made in the form of a bolt, which works up inclines.
b is a double sided striking plate bolt, a is an open sided box staple, with
opposite side gaps a², and c are counter inclines, on the staple, up which the
said bolt slides, on being struck by the said latch bolt of a lock or latch. 62 is
a snug on the bolt b, which traverses up the inclines a³ respectively, on the presented
bevelled fronts 61, of the bolt being struck as aforesaid.
It will be understood that the box staple, is a right and left handed one, to be fitted
either to a right or left-handed door.
Figure 12 represents another form of my invention, consisting of a box staple a,
opposite gapped sides a², guides a³, vertical sliding plate b, with bevelled lower end &,
which rests upon a stop a; so that on the bevel 6, being struck by the latch bolt, of
a closing door, the plate b, is raised, and again falls, on the said latch bolt coming
behind it.
Figure 13 represents a modification of figure 12. In this arrangement, the striking
plate is made in the form of a slide, to move horizontally, instead of vertically.
a is a box staple plate, and b is a double sided yielding striker plate, with bevel
presented edges, against which, the latch bolt of a lock, strikes, on the closing of a
door, and which striking plate works between top and bottom guides a³, and with the
bevel edges 62, coming in front of side gaps a² of the staple plate. c is a spring,
whose free end takes within a gap 68, while the striking plate is limited in its outward
motion, by a stop 6*. The spring c returns the striking plate always to a central
position, after having been struck by a lock of a closing door.
Figure 14 represents a modification of the first described arrangement. In this

page_text: form, the staple plate is made open on its front side, thus exposing the striker plate,
which is suspended from its upper part.
a is a staple, b is a striking plate, and a² the bracket part of the said staple, from
which the striker plate is hung.
Although I have represented the gaps a², upon both sides of the staple plate, yet
one side only, may be gapped, for a single sided staple.
It will be understood that the latch bolt, is released from behind the staple plate, by
the turning of the knob of the lock or latch, in the ordinary way.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that
what I claim is,―
First. A reversible or double sided box staple, with side gaps a², substantially as,
and for the purpose, as set forth.
Secondly. Gapping one side, or both sides, of box or other staples, or staple plates,
with openings a², wherethrough the end of a latch bolt, or the like, of a lock or latch,
passes, in getting to, and behind, the striking plate.
Thirdly. A lock or latch staple, consisting of an enclosing casing or plate a, with
a swinging striking plate b, whose front bevel part or parts 62, come in front of, or
before, a gap or gaps a³, substantially as described and set forth.
Fourthly. A lock or latch staple, consisting of a single or double sided inclined
striking plate or holt, (with a bevelled end or ends) working upon an incline or
inclines, substantially as described and set forth in figure 11.
Fifthly. A lock or latch staple, consisting of a framing a, (having a gapped side
or sides a³,) with a vertical sliding bolt or striking plate b, whose lower bevelled end,
comes in front of the said gaps a, and normally rests upon a stop at, as set forth in
figure 12.
Sixthly. A lock or latch staple, consisting of an enclosing casing or plate a, with
a sliding striking plate b, whose bevelled end or ends 6', come in front of, or before,
a gap or gaps a², mado within the sides of the said staple ; and the parts of
which said staple, are constructed, arranged and work, substantially as set forth in
figure 13.
Seventhly.-Making lock or latch staples, with yielding striking plates or their
equivalents, open fronted, as set forth in figure 14.
