I, HENRY VAUGHAN, of Standard Works, Willenhall, in the County of Stafford,
lock manufacturer, do hereby declare the nature of this invention to be as follows:-
The improvements refer to the fore-end of a lock or latch-case stamped in sheet
metal, and to the means whereby the same is fixed to the case; and the object is to
increase the strength of the case and to improve its appearance.
The fore-end of a stamped lock or latch-case, as usually constructed, is formed as a
plain plate projecting somewhat in front of the case, to which it is riveted by means
of rivets solid with the edge of the case passing through oblong openings in the
fore-end.
Now, according to this invention, a fillet or ledge is formed upon the fore-end so as
to project somewhat over the front of the case and thus hide the joint between the case
and the fore-end, and consequently considerably improve the appearance of the case,
besides materially strengthening it. The back edge of the fillet is rounded over to
give a better appearance. This fillet may be formed wide as a flange, if desired, and
when so formed the case is considerably strengthened.
The fore-end may be fixed to the case in the usual manner, or may be riveted
thereto by means of rivets passing through the flange at the back of the fore-end, or
passing through ears formed backwards from the fillet or ledge or from the flange, or
any convenient combination of these methods of fixture may be adopted.
It is preferred, for the sake of neatness of appearance, to shape the fore-end so as to
follow round parallel with the contour of the front of the case, instead of joining the
lines bounding the top and bottom of the fore-end direct to the front line of such fore-
end by means of plain curves as is usual.
The fore-end may be stamped, or may be cast in brass or malleable cast iron.

page_text: Improvements in or relating to Lock and Latch Cases of which the
Bodies are Stamped in Sheet Metal.
I, HENRY VAUGHAN, of Standard Works, Willenhall in the County of Stafford,
lock 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 reference being had to the accompanying drawings and the letters
of reference marked thereon (that is to say) :-
The improvements refer to the construction of the fore-end of a lock or latch case
stamped in sheet metal, and to the means whereby the same is fixed to the case;
and the object is, chiefly, to increase the strength of the case and to improve its
appearance.

The fore-end of a stamped lock or latch case, as usually constructed, is formed as a 1
plain plate projecting somewhat in front of the case, to which it is riveted by means
of rivets solid with the edge of the case passing through oblong openings in the
fore-end.
Now, according to this invention, a flange or ledge is formed upon the fore-end so
as to project somewhat over the front of the case and thus hide the joint between the
case and the fore-end, and consequently considerably improve the appearance of the
case, besides materially strengthening it. The fore-end may he fixed to the case in
the usual manner, but is, according to this invention, preferably, riveted thereto by
means of rivets passing through the flange at the back of the fore-end, or passing
through cars formed backwards from such flange. The invention comprises, also, the
employment of studs or a ledge projecting from the back or inner face of the fore-end,
in certain cases, as a support to the cap-plate.
This invention will be readily understood on reference to the accompanying
drawings, of which figure 1 illustrates in front elevation the forward end of a stamped
lock or latch case A with the "fore-end" B constructed and fixed thereto according to
this invention; figure 2 is a section taken on line of figure 1. The "fore-end" is
formed with a backwardly projecting flange or ledge a a which follows the contour of
the exterior of the front end of the case A. and fits immediately in front thereof, and
thus hides the joint between such case and the "fore-end" B, besides strengthening
The fore-end" is shewn as fixed to the case by means of rivets bbb
passing through corresponding ears formed out from the flange or ledge a a.
Hange may, if desired, be made sufficiently wide to receive the rivets without the need
for forming cars. The cap-plate C, is supported at its forward end by studs c c (or by
a ledge in lieu of such studs) projecting at the back of the "fore-end," and is supported
towards its back end upon a stud (or studs) projecting from the front plate of the case,
and is held to such stud by means of a screw, as will be readily understood.
the case.
The
The fore-end with its flange or ledge a a may be stamped, or may be cast in brass
or malleable cast iron; and, when cast, the studs ce may be cast therewith.

page_text: Figures 3 and 4 are corresponding views, respectively, to figures 1 and 2, but
illustrate the application of the invention to a case of a different shape. The parts in
these views corresponding to those in figures 1 and 2 are similarly lettered.
The means described, with reference to the drawings, by which the "fore-end" is
fixed to the case, may be employed also when no flange or ledge projects at the back
of the "fore-end," that is to say, the ears through which the rivets bbb pass may be
formed out from the back of the "fore-end" instead of from the flange a a as shewn.
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 :-
1. A fore-end of a stamped lock or latch case formed with a flange or ledge
projecting at the back thereof to fit around the exterior of the front end of the case,
substantially as described for the purposes set forth.
2. A fore-end of a stamped lock or latch case fixed to such case by means of rivets
passing through a flange or ledge projecting at the back thereof and fitting around the
exterior of the front of the case, or through ears projecting from such flange or ledge,
or direct from the fore-end, substantially as described.
3. The studs cc, or a ledge in lieu thereof, substantially as described, for the purpose
set forth.
