page_text: We, CHARLES DEAN, of Walsall Road, Willenhall in the County of Stafford, lock
manufacturer, and GEORGE GROVES, of Railway Street, Willenhall, aforesaid, lock
maker, do hereby declare the nature of this invention to be as follows:-
This invention consists in a construction of padlock according to which the shackle
is closed against an abutment which stands up from the lock case and is locked in
such position, and in which the shackle is unlocked and moved back from such
position by means of a key.
The inner end of the shackle is continued downwards into the body of the case
from the pin or pivot on which it turns, and a slot is formed in the inner end which
gears with a stud on a horizontally-sliding bolt which is moved by the key. The bolt
is fitted with a lever or levers or with a tumbler, in the usual manner of lock
mechanism of this character. The bolt, and consequently the shackle also, may be
moved to-and-fro by the key; but the shackle may be closed inwards by hand to lock
it, if desired, by forming an incline on the rear side of the locking part of the gating
of the lever, or each lever, or at the rear side of the locking stud of the tumbler, and
correspondingly inclining or rounding the leading side of the stump of the bolt which
gears with the lever, or levers, or with the tumbler, in which case the lever, levers, or
tumbler are raised by the stump and allow it and the bolt to pass in a forward
direction, as the shackle is pushed in.
The front and back plates of the case may be carried up, for the sake of appearance,
to form correspondingly-shaped cars on each side of the centre line of the case, as
seen in front or back elevation; and the ears on one side may form the front and
back of the abutment, and the remaining contour thereof above the case be formed
of a thin metal rim of the depth between the ears, thus forming a hollow abutment.

what within an opening formed therefor in the abutment. The cars are, preferably,"
-of-such-size and shape that the upper part of the shackle is, when closed in,.flush
with the upper edges of the cars between which it works, and so that no part of the
shackle, when closed in, projects beyond the ears, with the exception of course of
the part projecting therefrom towards the abutment.

We, CHARLES DEAN, of Walsall Road, Willenhall in the County of Stafford, lock
manufacturer, and GEORGE GROVES, of Railway. Street, Willenhall, aforesaid, lock
maker, do hereby declare the nature of this invention and in what manner the
samo is to be performed, to be particularly described and ascertained in and by
the following statement :-
:-
This invention consists in a construction of padlock according to which the shackle
is closed against or into an abutment and is locked in such position, and in which the
shackle is unlocked and moved back from such position by means of a key.
In order that the invention may be clearly understood we will describe it with
reference to the accompanying drawings, of which figure 1 is a front elevation of a
padlock constructed according to this invention, with the cap-plate removed so as to
expose the interior mechanism, and shows the parts in their locked position. Figure 2
is a corresponding view to figure 1, but shews the parts in their unlocked position.
In figure 2 also the shackle is shewn by broken lines so as to allow one of the pair
of cars, hereinafter described, between which it operates being shown throughout by
full lines.
The shackle A is pivotted to the case B by means of a pivot a similarly as padlock
shackles are usually pivotted, but preferably on the opposite side of the case in order
that the shackle may be unlocked by turning the key in the usual direction for unlocking,
as will be presently seen. The inner end of the shackle is continued downwards, as
shewn, into the body of the case from the point at which it is pivotted, and a slot c is
formed in the inner end thereof and gears with a stud d which projects from a hori-
zontally-sliding bolt C which is itself operated by the key in the usual manner of
operating such bolts, the bolt being fitted with a lever or levers or with a tumbler in
the usual manner of lock mechanism of this character. As the bolt C is moved
forwards and baokwards the inner end of the shackle is correspondingly moved
therewith and the outer end of the shackle is consequently moved alternately into its
locked position shewn by figure 1 and into its open position shewn by broken lines
figure 2. An abutment D is formed up at the top of the case, as shewn, and the
outer end of the shackle A when closed or locked bears against such abutment, or
preferably enters somewhat within it, as shewn by figure 1. This abutment may be
formed hollow, as shewn, for the sake of lightness. The bolt C, and consequently
the shackle also, may be moved both forwards and backwards by the the key; but
it is preferred to construct the mechanism so that the shackle may be closed inwards
by hand and be automatically locked as it is so closed in; and this is accomplished
by somewhat rounding or bevelling the upper forward edge of the stump e which
projects from the bolt into the gating of the lovers, and by bevelling the parts which
form partial divisions between the forward and rear parts of the gatings, whereby, it
will be seen, that as the outer end of the shackle is pushed in towards the abutment D

page_text: the inner end of the shackle draws forward the bolt C, and the stump e bearing
against the bevelled parts of the levers raises such levers and allows the stump to
pass into the forward parts of the gatings, at which point the levers again descend
and lock the bolt and consequently also the shackle. When a tumbler is employed in
lieu of levers the rear side of the locking stud thereof and the forward side of the
stump on the bolt which gears with such stud are suitably bevelled or rounded to
cause the lifting of the tumbler as the bolt is pressed forwards.
The front and back sides of the abutment I may be formed by simply carrying up
the front and back plates of the case, and cars E may be carried up from the front
and back plates of the case on the opposite side of the centre line g thereof to that on
which the abutment occurs. The shackle when in position is more or less between the
ears E, and these cars are, preferably, of such size and shape that the upper part of
the shackle is, when closed in, flush with the upper edges thereof, and so that no part
of the shackle, when closed in, projects beyond the cars, with the exception of course
of the part projecting therefrom towards the abutment. It is preferred, for the sake of
appearance, that the contour of the abutment D and of the ears E, as seen in front
or back elevation, correspond with one another and that they be spaced at equal
distances on opposite sides of the centre line
of the case.
C
It will be obvious that in lieu of forming the slot. c in the inner end of the shackle A
and carrying the stud d on the sliding-bolt C, the slot may be formed in the sliding-
.bolt and the stud be carried by the inner end of the shackle.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. A padlock provided with a pivotted shackle of which the end on the inner side
of the pivot is operated by mechanism within the case whereby the shackle may be
opened out, as the interior mechanism is unlocked, by means of a key, substantially as
described.
2. A padlock provided with a pivotted shackle of which the end on the inner side
of the pivot gears with and is operated, to move open the outer end, by a sliding-bolt
which is itself drawn back or unlocked by a key, substantially as described.
3. A padlock provided with a pivotted shackle of which the end on the inner side
of the pivot gears with and is operated, to move open the outer end, by a sliding-bolt
which is itself drawn back or unlocked by a key, and of which shackle the outer end
closes, when locked, against or partially into an abutment which is carried up from
the case, substantially as described.
4. A padlock constructed substantially as described and shewn by the drawings
herewith, whether fitted with lever lock mechanism, as shewn, or with other usual or
convenient form of lock mechanism in which a sliding-bolt is drawn back or unlocked
by means of a key.
