PROVISIONAL SPECIFICATION.
Improvements in the Construction of Scarboro' Trunk Locks.
I, WILLIAM WAKELAM of Walsall Road Willenhall in the County of Stafford
Lock Manufacturer do hereby declare the nature of this invention to be as
follows :-
The whole of the mechanism of this lock is secured to the part of the lock called
the back plate, which is made larger than the cap, and by which the lock is secured
to the trunk. The said cap is bumped up out of sheet metal with the edges
at right angles to the face so as to form a case over the working parts and
it is secured to the back plate by being rivited through the back plate. The
hole that is made in the back plate to receive the pin end of the key is raised
into the lock by the metal round the hole being cupped inwards, so that the
pin end of the key shall not bind when the lock is secured to the trunk. The
hinge of the hasp is made as follows, the top part of the hasp is pressed out
the required shape and an oblong hole, the same width as the bottom part of
the hasp, is made in it, about of an inch from the edge, which said edge is then
curled up to form a small barrel round which the bottom part of the hasp is
turned, which forms the hinge.

I, WILLIAM WAKELAM of 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 :-
The whole of the mechanism of this lock is secured to the part of the lock
called the back plate, which is made larger than the cap and by which the lock is
secured to the trunk. The said cap is bumped up out of sheet metal with the
edges at right angles to the face so as to form case over the working parts of
the lock, and it is secured to the back plate by being rivited through the back
plate. The pin hole that is made in the back plate to receive the pin end of
the key is raised into the lock, by the metal round the hole being cupped
inwards, so that the pin end of the key shall not bind when the lock is secured
to the trunk. The hinge of the hasp is made as follows, the top part of the
hasp is pressed out the required shape and an oblong hole the same width as
the bottom part of the hasp is made in it about of an inch from the edge
which said edge is then curled up to form a small barrel round which the bottom
part of the hasp is turned which forms the hinge.
In order that this invention may be clearly understood I will describe it in
conjunction with the accompanying drawings.
Fig. 1 is the back plate cut to the required shape showing the raised pin hole A.
Fig. 2 is the shape of the cap before the edges B are turned to right angles to B*.

page_text: After the edges B' have been turned, the cap is then placed on the back plate in
the position shown by the dotted lines Fig. 1.
Fig. 3 shows the cap B² fixed in position on the back plate.
To fix the cap B2 to the back plate a small rivit C Fig. 2 is secured to two or
more parts of the cap marked B' and when the cap is fitted to the back plate small
holes are made in it as D Fig. 1 to receive the rivit, or lips may be left on the
edge of the parts B' as E Fig. 2 which would pass through the small slot F Fig. 1
and then turned level with the back plate.
Fig. 4 is a section through the centre of the lock showing the metal round the
pin hole A cupped inwards.
Fig. 5 is the top part of the hasp showing oblong hole G through which the
bottom part of the hasp is passed.
His turned up to form a small barrel.
Fig. 6 is the bottom part of the hasp, I is the part that is passed through
the oblong hole G Fig. 5 and which is then turned round H Fig. 5.
Fig. 7 is a section through the hasp showing the joint or hinge completed.
Having now ascertained the nature of my said invention and in what manner the
same is to be performed I declare that what I claim is
1st. The herein before described manner of constructing a Scarboro trunk lock
with the back plate projecting over and being larger than the cap or case.
2nd. The construction of a Scarboro trunk lock hasp wherein the joint or hinge
between the top and bottom parts, is so made and secured substantially as described
herein.
3rd. The cupping upwards of the metal in the back plate round the pin hole so
that the key shall not bind against the trunk substantially the same as shown
herein.
Dated this 28th day of September 1895.
