Improvements in the Manufacture of the Cases or Bodies of Locks and
other like Cases.
We, SAMUEL WILKES and JONAH WILKES, of Excelsior Works, Bloxwich, in
the County of Stafford, Lock Manufacturers, and WILLIAM JOHN GOODMAN, of 37,
Harrison Street, Bloxwich, aforesaid, Lock Maker, do hereby declare the nature
of our said invention to be as follows:-
Our invention has for its object improvements in the manufacture of the cases
or bodies of locks and other like cases by which we greatly facilitate the said
manufacture and produce more exact results as to duplication and exact finish
and at less cost than heretofore. In the ordinary way of making the bodies or
cases of locks and of similar cases such for instance as sash pulley cases &c., it
has been the practice to rivet or braze the front plate to the sides or body part
or parts or by casting the front and side or sides together which necessitates
considerable filing and fitting-we refer more particularly to those locks and
other cases which are sunk into a mortice in the edge of the door, and we will
describe our invention as used for this particular purpose.
In our new manufacture of the cases or bodies of locks, sash pulley cases and
the like we commence our manufacture by cutting blanks of sheet metal of such
shape and with such piercings that when doubled or bent up by a machine or tool
it is first brought into the shape of a U and with both of the sides the same or of
different lengths. We then place the U piece in a die or dies press down by one
or more operations the base of the U formation so as to flatten the base and at the
same time to form from the metal a flange on one or both sides of double thickness
and of great firmness and good surface finish and exactness in regard to size. The
mechanism of the lock or mounting of the pulley or pullies etc. in the case is
then proceeded with. In some cases to facilitate the introduction of the mount-
ings one leg of the U piece is left short so as to only form a double thickness
flange and a separate cap or cover plate is added and closed in a recess in the
flange or otherwise added. In other cases end wings are cut upon the blank and
the U piece is flattened at its base without side flanges the end wings being
sufficient to receive the screw holes to fasten into the mortice. These end wings
may be pierced from the blank in circular shape so that the mortice

Improvements in the Manufacture of the Cases or Bodies of Locks and
other like Cases.
We, SAMUEL WILKES and JONAII WILKES, of Excelsior Works, Bloxwich, in
the County of Stafford, Lock Manufacturers, and WILLIAM JOHN GOODMAN, of 37,
Harrison Street, Bloxwich, aforesaid, Lock Maker, do hereby declare the nature
of our said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
Our invention has for its object improvements in the manufacture of the cases
or bodies of locks and other like cases by which we greatly facilitate the said
manufacture and produce more exact results as to duplication and exact finish
and at less cost than heretofore. In the ordinary way of making the bodies or
cases of locks and of similar cases such for instance as sash pulley cases etc. it
has been the practice to rivet or braze the front plate to the sides or body part
or parts or by casting the front and side or sides together which necessitates
considerable filing and fitting-we refer more particularly to those locks and
other cases which are sunk into a mortice in the edge of the door and we will
describe our invention as used for this particular purpose.
In our new manufacture of the cases or bodies of locks, sash pulley cases and
the like we commence our manufacture by cutting blanks of sheet metal of such
shape and with such piercings that when doubled or bent up by a machine or tool
it is first brought up into the shape of a U and with both of the sides the same or
of different lengths. We then place the U piece in a die or dies press down by one
or more operations the base of the U formation so as to flatten the base and at the
same time to form from the metal a flange on one or both sides of double thickness
and of great firmness and good surface finish and exactness in regard to size. The
mechanism of the lock or mounting of the pulley or pullies etc., in the case is
then proceeded with. In some cases to facilitate the introduction of the mount-
ings one leg of the U piece is left short so as to only form a double thickness
flange and a separate cap or cover plate is added and closed in a recess in the
flange or otherwise added. In other cases end wings are cut upon the blank and
the U piece is flattened at its base without side flanges the end wings being
sufficient to receive the screw holes to fasten into the mortice. These end wings
may be pierced from the blank in circular shape so that the mortice may be com-
menced with a centre boring bit the centre of the bit forming
tho screw hole for mounting the lock or other article which saves
some labour and facilitates the mounting. The front of the locks
when made as above described may be formed with a groove or
depression which is made in the press from the single thickness of metal and

page_text: which serves to bind the doubled or flanged portion well together and at the
same time effects a pretty and convenient finish. We may close in the ends of the
body by leaving the sides a little longer and this may be done at one or both sides
and the cases may be used as brackets as we do not confine ourselves to use them
in mortices.
In order that our invention may be more clearly understood and easily carried
into practical effect we have appended hereunto two double sized sheets of draw-
ings upon which we have illustrated examples of our lock and other like cases
or bodies.

In carrying our invention into practice we cut and pierce the blank A see
Figure 3 from sheet metal by suitable tools having the side wings aa and end
pieces a³ ³. This blank is then doubled or bent U shape as shewn at Figures 4
& 5 or it may be bent into the shape as shewn at Figure 6. We then place the
U piece in a die or dies and press down or flatten by one or more operations the
base of the U formation so as to form from the metal of this flattened out base
the flanges on both sides of the parts or sides a a¹ which flanges are of
double thickness of metal and consequently strong and firm as clearly shewn at
Figures 1, 7, 8 and 9. The edges of the end pieces a² a² are turned over and
flattened down by the same operation and these end pieces have the holes at a
pierced or drilled in them for the reception of the screws for fixing the lock in the
mortice of the door as clearly shewn at Figure 6. The holes as as formed in the
sides of wings a a¹ are for the boss of the bolt D to fit into and the sides or
wings a are held together or in position by the rivets or screws s¹ which
screws also hold the spring S for operating the bolt as shewn in dotted lines
at Figure 1.
At Figures 10 11 and 12 we have shewn a slight modification which is intended
to facilitate the introduction of the mechanism of the lock. In this case when
forming the blank we leave off one of the wings or sides a¹ and form the recess aª

to receive the
In the modification as shewn at Figures 13, 14 15 16 and 17 when forming the
metal blank A we leave the end wings a³ ³ as shewn at Figure 13. This blank
is then bent up U shape by suitable tools so as to form the sides a¹ a¹ and
flattened at its base without leaving side flanges as clearly shewn at Figures 16
and 17. The end wings as as being drilled or pierced with holes
screws to fasten the lock into the mortice and these
wings as as may be cut from the sheet metal circular shape So
that the mortice may be commenced with a centre boring bit the centre of the
bit forming the screw hole which saves some labour and facilitates the mounting.
When flattening the base of this U piece the edges are preferably made to bulge
slightly beyond the sides a¹ a¹ so that a better fit is ensured when fixing the
lock in the mortice as clearly shewn at Figure 17. A brass facing may be fixed
to the front of the lock if desired so as to give it a better finish. The front of
the lock cases when made as herein described may in some cases be formed with
the groove or depression a as shewn at Figure 18 which serves to bind the double
thickness of metal at the flanges a³ ³ well together and at the same time
strengthens the case and forms a neat finish. We may also if desired close in the
end or ends of the body by leaving the sides a¹ a' a little longer and then turning
these extended portions over.
At Figures 19 20 and 21 we have shewn the application of our invention to the
pulley bracket B which is formed from a suitable metal blank. This blank is
then bent U shape in the same manner as previously described and the base of
the flattened so as to form the flanges 61 71 on both sides of the parts 62 3.
The holes are pierced in these sides to form the bearings in which the pulley P
is mounted on its axis ¹ and one of the sides 62 is left a little longer so as to close
in the ends of the body which end pieces are formed so as to fit into notches
formed in the ends of the other side piece as clearly shewn.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
