Improvements in the Construction of Padlock. Cases.
T, WILLIAM WAKELAM of No. 11 Walsall Road Willenhall in the County of
Stafford, Lock Manufacturer do hereby declare. the nature of this invention to be
as follows:-
:-
This invention has reference to the construction and fixing together of the parts
that comprise the onses of pad locks that are made of sheet metal.
Herctofore when the cases of pad locks have been made of sheet metal it has
been necessary that they should be of good strength so that they would stand the
strain of riviting to fix the parts together, but by my invention the oases will bo
secured together without the use of viting.
'
The front case is stamped out, preferably of circular form, with the edges
bumped or otherwise turned up to form the Hange or roundabout, and round the
edges of the same notches are cut out at required distances, sufficiently wide to
receive the oars that are left on the edges of the back platepand just deep enough
to sink the back plate to the level of the edges of the flange or roundabout.
Iloles are pressed out of the said roundabout for the spoon and loop of the shackle
to be fitted to the inside mechanism of the lock. The whole of the internal
mechanism of the lock are secured to the back plate, the ears of which are then
dropped into the notches that are in the edge of the roundabout and then where
back plate and roundabout join together (namely the edges of the back plate and
the inside edge of the roundabout) they are brazed or soldered, thus securing the
parts of the case together without the use of any rivits or the like.

Improvements in the' Construction of Padlock Cases.
1, WILLIAM WAKELAM of No. 11 Walsall Road 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 :—
This invention bas reference to the construction and fixing together of the parts
that comprise the cases of pad locks. that are made of sheet metal. Heretofore
when the cases of pad locks have been made of sheet metal it has been necessary
that they should be of good strength so that they would stand the strain of riviting
to fix the parts together but by my invention the cases will be secured together
without the use of riviting. The front case is stamped out, preferably of circular
form, with the edges bumped or otherwise turned up to form the flange or
1oundabout, and round the edges of the same notches are cut out at required
distances, sufficiently wide, to receive the ears that are left on the edges of the
back plate, and just deep enough to sink the back plate to the level of the edges of
the flange or roundabout. Holes are pressed out of the said roundabout for the
spoon and loop of the shackle to be fitted to the inside mechanism of the lock.

page_text: The whole of the internal mechanism of the lock are secured to the back plate the
ears of which are then dropped into the notches that are in the edge of the
roundabout and then where the back plate and roundabout join togethei (namely
the edge of the back plate and inside edge of the roundabout) they are brazed
oi soldered, thus securing the parts of the case together without the use of any
rivets or the like.
I will now describe this invention in conjunction with the accompanying sheet
of diawings the same letters of reference occuring on different figures indicate
corresponding parts
Fig. 1 is the shape of the flat piere of metal pressed out to form the font part
of the case and the roundabout, showing the notches a that are cut out to receive
the ears that are on the edge of the back plate Three notches only are shown
although more may be put in if required bare the holes made in the roundabout
for the spoon and loop of the shackle to work in The edge is the part that is
bumped or otherwise turned up, on the dotted line Fig. 1, to form the roundabout
at right angles to the front plate d Figs. 1 and 2.
Figs 2 & 3 show the shackle by dotted lines as it will be fixed through the
holes b. Fig. 1.
Fig 4 is the plan of the back plate e showing the three cars e' that are made to
fit in the notches a in the roundabout c when the parts are secured and fixed
together by being brazed or soldered where the parts meet as shown by thick lines
on Figs 3. 5 & 6.
2
Fig 5 is a section through Fig. 3 showing that the back plate is sunk so that
the outside face of the backplate e is level with the edge of the roundabout c
When for strength or weight, it is desirable that the back plate e should be very
strong two or more pieces of inetal may be used as shown by h Fig 6
The lock case shown by the diawings is of circular form, but this improvement
can be applied to any shape and it can be made any depth that may be required by
making the roundabout c wider.
By this invention it will be able for the flange or roundabout e to be made in
one piece with the back plate e, or the back plate e and front plate d could both be
separate from the roundabout c and all secured together by brazing and soldering
as before mentioned.
Having now particularly descubed and ascertained the nature of my said mven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st The making of a pad lock case with ears on the back plate, and notches in
the roundabout, substantially as described.
2nd The brazing or soldering together of the back plate and roundabout, or
fiont plate and roundabout, substantially as described.
3rd. The construction of a pad lock case and method of securing same together
without rivets, substantially as described.
