We, JAMES FRAKES and JOHN LOWE both of 19 Spout Lane, Walsall, in the county
of Stafford, Lock Manufacturers, do hereby declare the nature of this Invention to be
as follows:
The main object of our invention is the improved construction of the cap or small
inner plate covering the bolt in padlocks.
In padlocks, as hitherto made, the said cap consists of a large plate secured to the
lock plate by two upright pieces. The holt lies between the said plate and cap, being
guided by notches in the upright pieces. The guide pin for the key barrel projects
through a slot in the cap, which permits the passage of the key wards through it.
According to our present invention we dispense with the said slotted cap plate and
employ only a small narrow cap plate, behind which the bolt works. One end of the
is rivetted to an upright piece, which is notched to guide the tail end of the
soll, while the othetead of the cap is formed with a small projection, which enters a
hole in another upright, which said hole also serves to guide the forward end of
the boli.
The principal advantages of our invention are, that cap plates made according
to our invention are cheaper and smaller than those as hitherto constructed, while at
the same time forming an equally firm and effective support and guard for the bolt.

page_text: We, JAMES FRAKES, and JOHN LOWE, both of 19 Spout Lane, Walsall in the County
of Stafford, lock manufacturers, 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) :-
:―
This invention relates to the construction of such padlocks as are required to have a
cap or bridge intermediate between the front and back plates of the case; and refers
to improvements in the construction and means of fixture within the case, of such cap
or bridge.
In such padlocks, as usually hitherto constructed, the cap or bridge is not carried
up in front of the bolt, and is riveted to two stumps which are themselves riveted to
the back plate of the case. The bolt is carried to be capable of sliding in two cheeks
riveted to the back plate of the case. The forward end or head of the bolt slides through
an opening pierced in the forward check, and the tail end of the holt slides in a notch
formed in the hinder check, and is prevented from moving out of the notch by riveting
over the outer edges of the notch towards one another. This is a clumsy and insecure
method of retaining the tail within the notch.
Now, the main object of this invention is to substitute a small narrow cap or bridge
for the large one usually employed, and to fix it to the checks which carry the bolt, and
thus dispense with the stumps hitherto employed for fixing the cap or bridge, and also
avoid the necessity for riveting the edges of the notch in the hinder cheek towards one
another and at the same time more securely retain the tail of the bolt within the hinder
cheek; but this invention has the further object also of extending the upper part of
the cap or bridge usually employed, and fixing it to the cheeks which carry the bolt,
just as and for the same purpose as the small narrow cap or bridge is fixed.
This invention will be readily understood on reference to the accompanying drawings,
of which figure 1 is a front elevation of a padlock with the front plate of the case and
also the shackle removed, shewing a small narrow cap or bridge fixed to the checks
which carry the bolt. The usual tumbler and spring are omitted, the parts only being
shewn which are necessary to make the invention clear. Figure 2 is a side elevation of
figure 1, looking in the direction of the arrow a, but with the rim of the case removed;
and figure 3 is a corresponding view to figure 2, shewing the opposite side of figure 1.
A is the back plate of the case, B B the rim, C the bolt of which the head
through an opening pierced in the front cheek D, and of which the tail e slides within
a notch in the hinder check E. F is the guide or drill-pin for the key barrel. The
cap or bridge is formed of a small narrow plate G having a small projecting part e
which is passed, immediately in front of the head of the holt, through the opening in
the front cheek (such opening being made larger than usual to admit thereof) to retain
the front end of the cap or bridge, the hinder end of such cap or bridge being
fixed to the hinder cheek by means of a rivet formed solid with such cheek.
passes

page_text: It will be seen that the cap or bridge securely prevents the tail of the bolt
from getting out of the notch in the hinder cheek, and avoids the necessity of
riveting the edges of such notch towards one another. The hinder check is, preferably,
made somewhat deeper than usual to permit of the convenient employment of the
rivet.
Figures 4, 5, and 6, correspond, respectively, to figures 1, 2 and 3, but shew a cap
or bridge of the usual type formed, according to this invention, with an upward
extention and fixed exactly in the manner of the small narrow cap or bridge illustrated
by figures 1, 2 and 3, the ordinary stumps employed for fixing a cap or bridge being,
in this case also, dispensed with. The parts in these views corresponding to those in
figures 1, 2 and 3 are correspondingly lettered. The cap or bridge Ghas a small
projecting part e exactly as and for the purpose of the part e figures 1 and 2, and the
opposite side of the cap or bridge G₁is fixed to the hinder cheek E by means of a
rivet just as the small narrow cap G is fixed. The check E is shown somewhat
deeper in this arrangement than in that shewn by figures 1, 2 and 3, so as to give
a better support to the cap than would be given by a narrower cheek. The cap
is shewn with a key hole therethrough, but it may be formed in any manner in
which such caps are required.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim in a
padlock required to have a cap or bridge intermediate between the front and back
plates of the
case, is :-
:-
1. Such cap or bridge formed as a narrow plate and fixed to the cheeks which
carry the bolt, substantially as described, for the purpose set forth.
2. Such cap
or plate formed with an upward extension and fixed to the cheeks
which carry the bolt, substantially as described for the purpose set forth.
3. Such cap or plate fixed to the checks which carry the bolt, substantially as
described for the purpose set forth.
4. The means, substantially as described with reference to the drawings herewith,
by which such cap or bridge is fixed to the cheeks which carry the bolt, for the
purpose set forth.
5. The means, substantially as herein described with reference to the drawings
herewith, by which such cap or bridge is held to the front check.
