1, JAMES WOODWARD, of the firm of Benjamin Walters and Company, of 154
North Street, Wolverhampton in the County, of Stafford, lock manufacturers, do
hereby declare the nature of this invention to be as follows
This invention relates to "rounded-rimmed "lock and latch cases, that is to lock
and latch cases which have the rims formed to a rounded section on the exterior.
Hitherto, it has been usual with cases of this description to place the plate and cap
against the edges of the rim and to rivet them thereto by means of rivets formed with
or fixed inside the rim, the edges of the plate and cap being then filed down to conform
to the rounded exterior of the rim. A considerable amount of labour is involved in
the riveting of the plate and cap and in filing them down as described, and the plate
and cap are weakened near to the rivet holes by the filing of the edges.
The object of this invention is to avoid the employment of any rivets for fixing the
cap and of more than one rivet for fixing the plate, to entirely avoid the necessity for
filing the edges of the plate and cap after they are fixed in place, and generally to
improve the construction and appearance of the case.
The above object is effected, according to this invention, by rolling or otherwise
forming the metal for the rim with a rebate on each inner edge, so that the plate and
cap may be let into the rim flush with the back and front faces thereof, respectively.
The plate and cap are held together, and consequently also securely within the rim,
by means of screws passing through the cap and screwed into studs fixed to the
plate but for the purpose of holding the plate in position within the rim until
the cap is fixed in place, a tongue projecting at the front edge of the plate enters a
corresponding recess formed therefor in the "fore-end" and thus secures the front
end of the plate, and a single rivet formed with or fixed to the inside of the rim, or a
screw passing through an eye or snug formed with or fixed to the inside of the rim,
secures the back end of the plate.
Dated this Twenty fourth day of February 1887.

Improvements in Rounded-rimmed Lock and Latch Cases.
I, JAMES WOODWARD, of the firm of Benjamin Walters and Company, of 154
North Street, Wolverhampton in the County of Stafford, lock 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, reference being had to the accompanying drawings and the letters of
reference marked thereon (that is to say) :-
-
This invention relates to "rounded-rimmed "lock and latch cases, that is to lock
and latch cases which have the rims formed to a rounded section on the exterior.
Hitherto, it has been usual with cases of this description to place the plate and cap
against the edges of the rim and to rivet them thereto by means of rivets formed with
or fixed inside the rim, the edges of the plate and cap being then filed down to
conform to the rounded exterior of the rim. A considerable amount of labour is
involved in the riveting of the plate and cap and in filing them down as described,
and the plate and cap are weakened near to the rivet holes by the filing of the
edges.
The object of this invention is, chiefly, to avoid the necessity for filing the edges of
the plate and cap after they are fixed in place, and, further, to avoid the employment
of any rivets for fixing the cap, and of more than one rivet for fixing the plate; and
generally to improve the construction and appearance of the case.
According to this invention the metal for the rim is formed by rolling or otherwise,
with a rebate on each inner edge, so that the plate and cap may be let into the rip
flush with the back and front faces thereof, respectively; and the plate and cap are
held together, and consequently also securely within the rim, by means of screws
passing through the cap and screwed into studs fixed to the plate, or screwed direct
into the plate in which case the cap bears upon suitable studs carried by the plate so
as to prevent it from buckling inwards; but for the purpose of holding the plate in
position within the rim until the cap is fixed in place, or at any time the cap is
removed, a tongue projecting at the front edge of the plate enters a corresponding
recess formed therefor in the "fore-end" and thus secures the front end of the plate,
and a single rivet formed with or fixed to the inside of the rim, or a screw passing
through an eye or snug formed with or fixed to the inside of the rim, secures the
back end of the plate.
Referring to the drawings herewith, figure 1 represents in front elevation a
rounded-rimmed lock or latch case constructed according to this invention, but with
the cap removed and the screws for holding it on shewn in section; figure 2 is a
section taken on line xx of figure 1; figure 3 is an inside view of the fore-end, shewn
as detached from the rim ; and figure 4 is an elevation of the front end of the plate,
the remaining portion being shewn as broken away for convenience of illustration.
The rounded-rim A A is formed, preferably by rolling, to the entire thickness of the
case and to the section shewn at figure 2, that is with the outer face curved or rounded

page_text: across its entire width, and with rebates (or rabbets) along the edges of the inner face
to receive the plate B and cap C, respectively. The rim may be fixed to the fore-end D
in any convenient manner. The method adopted in the case illustrated consists in
shouldering down the rim at each end sideways and riveting the reduced parts into
holes (see figure 3) in the fore-end. The cap and plate are held firmly in place
within their corresponding rebates in the rim by means of screws c c passing through
the cap C and screwed into studs E E fixed to the plate B. In order, however, to
retain the plate within the rim until the cap is fixed in place, or during any time the
cap may be removed, a tongue d is formed to project at the front end of the plate
and enters, when the plate is placed in position, within a corresponding recess d¹
formed therefor in the fore-end D; and a rivet e, fixed inside the back end of the
rim, holds the hinder end of the plate.
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 in respect
of rounded-rimmed lock and latch cases, is :-
1. A rim formed, preferably by rolling, with a curved or rounded outer side or face,
and with rebates along its inner edges to receive the cap and plate of the case,
substantially as described and shewn, for the purpose or purposes set forth.
