PROVISIONAL SPECIFICATION.
Improvements in Door Locks and Latches.
We, WILLIAM CROSS and JOHN WILLIAM CROSs, both of West Bromwich in
the County of Stafford, Manufacturers do hereby declare the nature of this invention
to be as follows:-
This invention pertains to lock and latch attachments known in commerce as
"box staples."
These said articles, viz., box staples, are connected to the stile of a door by screws,
passing through flanges, formed alike unto plates, directed beyond the top and
bottom sides of the hooded or semi-enclosed part."
The entrance to the hooded or box part, at bottom, is open or unbridged, so that
the walls of the erect or outstanding box part are supported by the top and bottom
flanges, which are directed in the same plane as the bottom or underside of the
staple.
By this limited means of flanged attachment, the said articles when in position,
are insecurely affixed, owing generally to the breadth of the stile limited.
The object of our improvements is a better and additional means for securing the
said box staples in position.
In carrying out one form of our invention, we take an ordinary box body part,
with extended flap or flange members, directed from the upper and lower base parts.
of the same, and directly inwardly at right angles to the said flap parts is a
supplementary flange, extending or running along the whole front of the said box
staple.
Thus, the base of the box body part comprehends a right angle, with the front
flap or front side, forming the inwardly directed web, and the end flaps, forming the
other and front side webs.
The mouth or opening of the box part is comprehended between the sides, top, or
striking edges, and the inner presented edge of the additional plate front side,
which is pierced with screw holes wherethrough screws pass, in making the
attachment to a stile. It will thus be understood that the screws or securing
means, which pass through the front web member, pass in a direction at right
angles to that which the screws take in passing through the end web members.
The side flange or web member screws, have the advantage of taking through
the broader direction of the stile, and thereby hold the attachment more securely
than heretofore, as long and large screws are capable of being used, in addition to
the. ordinary screw attachment, whilst the attachment is to an extent prevented
from getting away, by the angle formation of the same clipping the corners of the
stile.
Instead of the front member, flap, or flange bridging the front of the staple, the
same may be open in the middle, but with extensions or web parts at the ends of the
said front.
Dated this 7th day of September 1892.

Improvements in Door Locks and Latches.
We, WILLIAM CROSS, and JOHN WILLIAM CROSS, both of West Bromwich in
the County of Stafford, Manufacturers, 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 pertains to lock and latch attachments, known in commerce as cap
or box staples.
These said articles, viz., cap or box staples, are connected to the stile of a door
by screws passing through flanges, formed alike unto plates, directed beyond the top
and bottom sides of the hooded or semi-enclosed part.
The entrance to the hooded or box part, at bottom, is open or unbridged, so that
the walls of the erect or outstanding box part are supported by the top and bottom
flanges, which are directed in the same plane as the bottom or underside of the
staple.
By this limited means of Hanged attachment, the said articles when in position
are insecurely affixed, owing generally to the breadth of the stiles being limited.
The object of our improvements is a better and additional means for securing the
said box staples in position.
In carrying out one form of our invention, we take an ordinary box body part,
with extended flap or flange members, directed from the upper and lower base parts
of the same, and directed inwardly at right angles to the said flap parts is a
supplementary flange, extending or running along the whole front of the said box
staples.
Thus, the base of the box body part comprehends a right angle, with the front
flap, or front side, forming the inwardly directed web, and the end flaps, forming
the other and front side webs.
The mouth or opening of the box part is comprehended between the sides, top,
or striking edge and the inner presented edge of the additional plate front side,
which is pierced with screw holes, wherethrough screws pass, in making the
attachment to a stile or upright of a door frame. It will thus be understood that
the screws or securing means which pass through the front web member, pass in a
direction at right angles to that which the screws take in passing through the end
web members.
The side flange or web member screws, have the advantage of taking through
the broader direction of the stile, and thereby hold the attachment more securely
than heretofore, as long and large screws are capable of being used, in addition to
the ordinary screw attachments, whilst the attachment is to an extent prevented
from getting away by the angle formation of the same clipping the corners of the
stile.
Instead of the front member, flap or flange bridging the front of the staple, the
same may be open in the middle, but with extensions or web parts at the ends of
the said front.
Figure 1 of the accompanying drawing represents, in perspective, a cap staple,
made, or provided with improvements made, according to our invention.
Figure 2 represents a front elevation of the same, or that side provided with the
additional or supplementary flanged member which constitutes our improvement.
Figure 3 represents a back elevation of the box portion of the staple.
Figure 4 represents a section upon the dotted lines A B Figure 2, whilst Figure 5
shows a top side plan, showing the same fitted to a stile or door frame, and also
showing how the said door frame is embraced angularly.
a is the box body part, with a front opening a, and a striker part a³. a are top
and bottom side flap or flange members, whilst is the supplementary or additional

page_text: flap plate or attachment extending or running the whole length of the box
staple.
Both flaps are provided with screw-holes as, respectively.
It will be seen that the back of the said staple is open, and that by providing the
said box part with an angular embracing flange, additional security in the affixing is.
attained.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
In a cap or box staple, providing the same with or carrying the same upon, an
angular flange, or a right angled base or attachment plate, which embraces or clips
the two sides of the stile or upright of a door, substantially as, and for the purpose.
as, described and set forth.
