I, FREDERICK WILLIAM PINSON, of Dale Works Willenhall in the County
of Stafford, Lock Manufacturer do hereby declare the nature of this invention to
be as follows:-
This invention has for its object an improved method of constructing, each in
one piece of metal, the roundabouts of padlocks; and improved means of fixing
roundabouts of padlocks whether made according to such improved method, or each
made otherwise as an endless or continuous roundabout.
The improved method of constructing the roundabouts, according to this
invention; consists in cutting them off transversely from a tube of the size and
shape in transverse section of the required roundabouts as seen in front or back
elevation.
Roundabouts constructed according to the improved method above described are
quite plain throughout their entire length or circuit except for the holes which are
formed therein to receive the spoon ends of the shackles. They might, of course,
be fixed by means of stumps or rivets fixed to them and riveted to the front and
back plates of the case, but it is preferred for this purpose to use means which
constitute a further feature of the invention.
According to these means the lock mechanism is carried by a plate which is
.fixed to the back plate of the case, and the roundabout is placed around the plate
which carries the mechanism and is thereby kept in position sideways, and is held
securely between the front and back plates of the case, which are fixed together
at the proper distance apart by suitable distance pieces. The roundabouts require
therefore no preparation for fixing them in place. It will usually be found that
two stumps are sufficient for fixing together the plate carrying the mechanism and
the back plate of the case, and for fixing also the front plate. These stumps
are made each with one end formed as a rivet to pass through the thickness of
both the plate carrying the mechanism and the back plate, and with the other
end formed as a rivet to pass through the thickness of the front plate.
Roundabouts formed each as an endless roundabout in any manner besides that
above described, may be formed plain, and be fixed in the manner described in the
last preceding paragraph.

page_text: I, FREDERICK WILLIAM PINSON, of Dale Works, 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 has for its object an improved method of constructing, each in
one piece of metal, the roundabouts of padlocks; and improved meaus of fixing
roundabouts of padlocks whether made according to such improved method, or
each made otherwise as an endless or continuous roundabout, or in one piece of
metal.
The improved method of constructing the roundabouts, according to this
invention, consists in cutting them off transversely from a tube of the size and
shape in transverse section of the required roundabouts, as seen in front or back
elevation.
Roundabouts constructed according to the improved method above described are
quite plain throughout their entire length or circuit, except for the holes or
openings therein to receive the spoon ends of the shackles. These holes or
openings may be formed by punching or cutting out pieces of metal from the
roundabouts, or may be formed by leaving an open joint or slot down the
length of tube from which the roundabouts are cut off, a gap being thus left
in each roundabout at the part where the spoon end of the shackle is to pass
through.
The roundabouts might, of course, be fixed by means of stumps or rivets fixed
to them and riveted to the front and back plates of the cases; but it is preferred
for this purpose to use means which constitute a further feature of the invention.
According to these means, the lock mechanism of each lock is carried by a plate
which is fixed to the back plate of the case, and the roundabout is placed around
the plate which carries the mechanism and is thereby kept in position sideways;
and it is held securely between the front and back plates of the case by means of
rivets which are independent of the roundabout. The roundabout requires,
therefore, no preparation for fixing in place.
In order that the invention may be clearly understood, I will proceed to
describe a convenient application of the same with reference to the drawings
herewith, in which
Figure 1 represents a front elevation of a padlock with the cap-plate
removed;
Figure 2 is a vertical section taken on line xx of Figure 1, with the shackle
omitted;
Figure 3 is a plan of Figure 1, also with the shackle omitted;
Figure 4 is a detached view of one of the stumps used for fixing the plate
which carries the mechanism to the back-plate of the case, and for fixing the
cap-plate in place; and
Figure 5 represents a short length of tubing from which roundabouts for the lock
illustrated by Figures 1, 2 and 3 may be cut off.
The roundabout a is shewn to be of a plain rectangular shape, and to have a
hole formed therethrough to receive the spoon end c of the shackle d. This round-
about is cut off from a tube of rectangular section, such as that illustrated in side
elevation by Figure 5. The vertical broken lines e, Figure 5, indicate the cuts by
which the short sections of tube to form the roundabouts are separated. The
holes or openings to receive the spoon ends of the shackles are cut or punched
through the roundabouts when they are not intended to form complete gaps
therein, but gaps may be formed in the roundabouts to receive the spoon euds of

page_text: the shackles, without any special operation of punching to produce them, by
drawing the tube from which the roundabouts are to be cut off with an open joint
or slot f, indicated by the horizontal broken lines Figure 5, in such position, as
shewn, that when the roundabouts are cut off from the tube each will have the
left in proper position for receiving the spoon end of the shackle.
gap
The lock mechanism, which may be varied, of course, as required (the special
lock mechanism illustrated being shewn only by way of example), is carried by a
plate g which is itself fixed to the back-plate h of the lock case. The roundabout
is placed around the plate g and against the inner face of the back-plate h of the
cuse, and is thus kept in place sideways by the plate g. The cap-plate i is placed
against the outer face of the roundabout, and is held back by means of rivets j
which are independent of the roundabout. It is preferred to fix the plate g to the
back-plate h of the case by means of rivets k formed on the inner ends of stumps 1,
and to fix the cap-plate by means of rivets j formed on the outer ends of the
stumps 1.
It will readily be seen that, by utilizing the plate g to keep the roundabout a in
position sideways, no preparation of the roundabout is required for fixing it to the
front or back-plate of the case, and it may consequently be formed quite plain as
shewn, except for any hole formed therethrough.
It will now be obvious that other roundabouts, formed each in one continuous
length or of one piece of metal, besides those which are cut off from a tube in the
mauner above described, may be formed quite plain, except for any hole formed
therethrough, and be fixed in the manner above described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what mnauner the same is to be performed, I declare that what I
claim is :-
1. The improvements in the manufacture of padlocks which consist in cutting off
the roundabouts therefor from a metal tube of the required section, substantially
as described.
2. A padlock having a roundabout which is kept in place sideways by means of
a plate which is fixed against the back-plate of the case and carries the lock
mechanism, the said roundabout being held in position otherwise simply by being
between the front and back plates of the case, the means of holding together the
front and back-plates of the case and the plate carrying the mechanism being
independent of the roundabout, substantially as described.
3. A padlock having the lock mechanism carried by a plate which is fixed to
the back-plate of the case by means of rivets formed on the inner ends of stumps,
the roundabout being kept in place sideways by means of such plate and being
otherwise held in position simply by being between the front and back-plates of
the case, the front plate of. the case being fixed by means of rivets formed on
the outer ends of the same stumps on which the rivets are formed for fixing the
plate carrying the lock mechanism to the back-plate of the case, substantially as
described.
