PROVISIONAL SPECIFICATION.
Improvements in Certain Padlocks and other Locks.
We, THE CO-OPERATIVE PADLOCK SOCIETY, LIMITED, of Neale Street,
Walsall in the County of Stafford, Lock Manufacturers, and THOMAS WHITTICK,
of 24 Hall Lane, Walsall, aforesaid, Locksmith, do hereby declare the nature of
this invention to be as follows :―
This invention relates to padlocks, and other locks, in which the hinder end of
the bolt is guided through or within the notch of a cheek, and in which a tumbler
is used for engagement with the bolt. In such locks, as heretofore constructed,
the tumbler is pivoted to a pin fixed within the case specially for such purpose;
and the object of this invention is to avoid the need for such pin, by mounting the
tumbler direct to the cheek, and to effect such mounting in a manner which avoids
the need for drilling a hole through the tumbler.
The above object is accomplished, according to this invention, by simply forming
the tumbler with a notch which engages with the edge of the cheek. The tumbler
is securely prevented from disengaging its notch with the edge of the cheek by the
pressure of the spring against which it is moved.
The tumbler is thus in effect
pivoted to the cheek, instead of as usual to a pin fixed specially therefor.

Improvements in Certain Padlocks and other LOCKS.
We, THE CO-OPERATIVE PADLOCK SOCIETY, LIMITED, of Neale Street,
Walsall in the County of Stafford, Lock Manufacturers, and THOMAS WHITTICK,
of 24 Hall Lane, Walsall, aforesaid, Locksmith, 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 relates to padlocks, and other locks, in which the hinder end of
the bolt is guided through or within a cheek, and in which a tumbler is used for
engagement with the bolt. In locks heretofore so constructed the tumbler is
pivoted to a pin fixed within the case specially for such purpose; and the object
of this invention is to avoid the need for such pin, by mounting the tumbler direct
to the cheek, and to effect such mounting in a manner which avoids the need for
drilling a hole through the tumbler.
The above object is accomplished, according to this invention, by simply forming
the tumbler with a notch which engages with the edge of the cheek. The tumbler
is securely prevented from disengaging its notch with the edge of the cheek by the
pressure of the spring against which it is moved. The tumbler is thus in effect
pivoted to the cheek, instead of as usual to a pin fixed specially therefor.
In order that the invention may be clearly understood, we have illustrated the
same upon the accompanying sheet of drawings, as applied, by way of example, to
a padlock.

page_text: Figure 1 is a front elevation of the padlock with the cap-plate removed to
expose the interior mechanism, and the bolt is shewn by broken lines only so that
the tumbler may be clearly distinguishable.
Figure 2 is a detached view of the tumbler.
A is the bolt, shewn by broken lines only, and B is the cheek through which the
hinder end of the bolt is guided. C is the tumbler, and c a notch formed in the
hinder end thereof which is passed down over the upper edge of the cheek B, as
shewn by Figure 1. The spring D, against the pressure of which the tumbler is
raised, prevents the notch c from rising and becoming disengaged from the top
edge of the cheek B. The engagement of the notch c with the top edge of the
cheek, under the pressure exerted by the spring D, forms in effect a pivot attach-
ment, the tumbler turning, as it moves up and down, on the top edge of the cheek
as a fulcrum or centre. The notch c is formed to widen out or gape open somewhat
towards its open end to allow of the movement of the tumbler.
When the forward end of the bolt is guided also through a
cheek B shewn in Figure 1, the tumbler may, if desired, be
cheek in the manner in which it is shewn as engaged with the
being engaged with such latter cheek.

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 tumbler of a padlock or other lock formed with a notch by means of which
it is engaged with the edge of a cheek through or within which the bolt is guided,
substantially as described, for the purpose set forth.
2. A padlock having a tumbler formed with a notch c by means of which it is
engaged with the upper edge of the cheek B, substantially as described and shewn
by the drawings herewith, for the purpose set forth.
