JOHN CORMELL of Cheltenham in the County of Gloucester, Merchant do hereby
declare the nature of this invention to be as follows
This invention has for its object improved appearance with greater security.
According to this Invention which refers only to the sliding or striking portion of a
latch or catch and the striking box or plate thereto.
I form the striking part of a Latch by taking a bolt of a square round oblong or
other section and tapering where it projects from the lock to or near the centre so that
it shall reduce the sharp projections. I then cut a slot perpendicularly about as deep as
the latch is to project from the rim of lock or other fastening, I then fix a perpen-
dicular strip or bar of metal so that when the latch strikes the striking box the said
latch with its slot clips the strip or bar and prevents the said latch vibrating through
wind or other forces the slot enables the bolt or latch to be ornamentally rounded, the
slot may be substituted by a hole or other indent with a corresponding projection.

page_text: JOHN CORMELL of Cheltenham in the County of Gloucester Merchant 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 for its object improved appearance with greater security.
This Invention refers only to the sliding or striking portion of a latch or catch and
the striking plate or box thereon.
I form the striking part of a latch by taking a bolt of a square, round, oblong or
other section and tapering where it projects from the lock to or near the centre so that.
it shall reduce the sharp projections. I then cut a slot perpendicularly about as deep
as the latch is to project from the rim or face of lock or other fastening. I then fix a
perpendicular strip or tongue of metal, so that when the latch strikes the striking
plate or box, the said latch with its slot clips the strip or tongue and prevents the said
latch vibrating through wind or other forces, the slot enables the bolt or latch to be
ornamentally rounded.
The slot may be substituted by a hole or other indent with a corresponding
projection.
Having thus set forth the nature of my Invention I next proceed to describe it
with reference to the drawings and to the letters and Figures marked thereon.
Figure 1 is an elevation of a mortise lock and the striking plate B, a portion of the
lock is broken away to shew the mechanism of the Latching Bolt A to which my
Invention refers the striking plate is shown a little distance from the lock to shew the
latch A clearer.
Figure 2 is a side view of the striking plate with the tongue or bar C cast in it and
a section of the end of the latch clipping it.
Figure 3 is a sectional plan view of the latch A shewing the slot D.
Figure 4 is a side view of a striker box with the tongue C cast in it being more
suitable for rim or such like locks where a striking plate would not be convenient.
The letters A on Figures 1, 2 & 3 is what I describe as latching bolt or latch
the letters B on figures 1, 2 & 4 as striking plate or box the letter D on figure 3 as slot
or indent.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed 1 declare that what I claim is
1st to use the slot or groove in any shaped latch suitable for the Invention and the
corresponding bar or tongue in a striking plate or box and
2nd I claim to use any shaped indent or aperture in a latch or such like fastening
and a corresponding projection in the striking plate or box.
