page_text: I, ENOCH JONES, of 24 Doctor's Piece, Willenhall in the County of Stafford,
padlock 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 reference being had to the accompanying
drawings and the letters of reference marked thereon (that is to say):-
According to one part of this invention, the shackle of a padlock is formed in two
parts, one of which is fixed rigidly to the case and the other pivoted to the outer
end of the fixed part, and formed at its unconnected end to pass into the case and
be locked therein by engaging with a bolt.
A convenient form of application of this part of my invention is shewn by the
drawings herewith, of which both figures 1 and 2 illustrate front elevations of a
padlock, with the cap removed so as to clearly shew the interior. Figure 1 shews
the shackle open, and figure 2 shews it closed. The same parts, in each view, are
indicated by corresponding letters.
A is the padlock case, B B¹ the shackle, and C a vertically-sliding bolt. The part B
of the shackle is rigidly fixed within the case, by means of rivets a b, the former of
which fixes the part B to the back plate and cap of the case, and the latter of
which fixes an arm c, formed on the end of the part B, to the back-plate of the
'case. An edge view of the lower end of the part B is shewn by figure 3. The
part B¹ of the shackle is pivoted to the part B at d, and thus the shackle is divided,
approximately, into halves. The unconnected end of the part B¹ is shaped, as shewn,
to gear with a bolt-head e on the bolt C, when the part B¹ is closed in, as shewn
by figure 2. In the illustration the unconnected end of the part B₁, and also the
top of the bolt-head, are shewn bevelled or rounded, and the other parts to be so
arranged, that the padlock is self-latching; but the parts may, of course, be
arranged, as will be obvious, so as to be locked as well as unlocked, by the key.
f is a spring for throwing out the part B¹ of the shackle immediately it is
unlocked.
The shackle is conveniently and neatly formed to close up into a circular shape,
as shewn, and at the same time to admit of a considerable width of opening, but
such form is not, of course, essential.
This construction of padlock affords great facilities for constructing the shackle
of a size to enclose any desired area, independently of the size of the case.

page_text: According to another part of this invention a spring acts as the bolt of a padlock.
This bolt is moved back to unlock the shackle either by the bit of the key or by a
follower which is turned by means of a key fitting within a hole in the centre
thereof. The forward end of the bolt may be split, so that part operates as the
head of the bolt and part as a spring for throwing up the shackle immediately it is
unlocked.
This part of my invention will be readily understood on reference to the drawings
on sheet 2 herewith, of which figures 4 and 5 are corresponding views, respectively,
to figures 1 and 2 (sheet 1). Figure 6 is a plan of the spring hereinafter described;
and figure 7 is an edge view of the shackle, as seen from the spoon-end side when
fastened down as shewn by figure 5. Like letters of reference indicate like parts
throughout these views. D is the case, E the shackle, F a spring, having the
part F¹ formed to act as the bolt for locking the shackle. g is a shoulder on the
spoon-end of the shackle over which the front end of the part F¹ of the spring
takes to lock the shackle, as shewn by figure 5. G is a follower having a horn h
thereon, and the bolt head is moved back by inserting a plain square-ended key
into the follower and turning it so that the horn h moves back the part F, and
consequently therefore the part F¹ also, of the spring. i and are studs forming
stops to the forward and backward movement of the follower horn and spring.
kkare studs which act as guides to the movement of the part F1 of the spring.
The stud k does not, of course, pass under the spring m but only under the part F
and is stopped short so as to allow the spring m to be pressed down as shewn by
figure 5. is a support on the upperside of the stud k to support it against the
underside of the top of the case, and thus strengthen it to resist any upward pull.
The part F¹ is split so as to form, in addition to the bolt head, a spring m for
throwing up the shackle, and the spoon end of the shackle is shaped with a
shoulder n which bears upon and presses down the spring m as the shackle is
closed in. The part m is longer than the main portion of the part F¹ in order to
bear properly under the shoulder n.
The exact details may, of course, be considerably modified, for instance, a bitted
key may be employed in lieu of the key and follower, and the spring for throwing
up the shackle may be an independent spring, and may be pressed down by the nose
of the shackle instead of by a shoulder, or such spring may be dispensed with
altogether and the shackle be raised by hand. The spoon end of the shackle is
shewn in the drawing to be shaped so that it is self-locking as it is pushed down,
but this is, of course, not essential.
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, is :-
1. A padlock shackle formed in two parts, one being rigidly fixed to the case,
and the other hinged to the fixed part, substantially as described, for the purpose
set forth.
2. In a padlock, the combination of a shackle formed in two parts with a
vertically-sliding bolt within the case, substantially as described, for the purpose
set forth.
3. A padlock shackle formed in two parts and shaped to close up in a circular
form, substantially as described,
4. The padlock constructed and operating substantially as described with reference
to the accompanying drawings.
5. In a padlock, the employment of a spring as the bolt for locking the shackle,
substantially as described.
6. In a padlock, forming the end of a spring employed as the bolt split,
substantially as described and shewn, for the purpose set forth.
7. The spring F F¹ constructed and operating substantially as described and
shewn, for the purpose set forth.

page_text: 8. In a padlock, the spoon-end of the shackle formed with a shoulder to bear
upon the spring for throwing up the shackle, substantially as described and
shewn.
9. In a padlock the combination of a spring acting as the bolt, with a follower,
(or with a bitted key) substantially as described and shewn, for the purpose set
forth.
10. The padlock constructed and operating substantially as described, and shewn
