DI DUITICATION.
An Improvement in Padlocks.
I, JAMES FRAKES, of 19, Spout Lane, Walsall, Staffordshire, 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 consists of the herein described improvement in padlocks whereby
the construction of the padlock is simplified and therefore the cost of manufacture
is reduced.
I will describe my invention by referring to the accompanying drawing on
which
Figs. 1 and 2 are elevations of a padlock with my invention applied the front
cheek being removed so as to shew the internal mechanism the padlock being shewn
locked in Fig. 1 and unlocked in Fig. 2; Fig. 3 shews the shoot or bolt separately
and Fig. 4 shews separate views of the tumbler which according to this invention
is also constructed so as to serve as a guide for the back end of the shoot and render
the usual back ear or guide of the shoot unnecessary. Fig. 5 shews a modified
form of the said tumbler.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
According to this invention I make the tumbler A of the padlock of such a shape
that it will also form a guide for the back part of the shoot or bolt D and thus
render unnecessary the usual ear or guide for the back part of the bolt which in
the general way is fixed to the bottom plate or cheek B of the padlock. This will
be readily understood by an examination of my drawing where in Figs. 1, 2 and 4
it will be seen that the tumbler A is continued down in front of the shoot D and is
pivotted at a³ on to a pin C below the shoot or bolt D and is made with two back
projecting parts a¹ a² between which the back part d' of the shoot or bolt D is
situated these parts a¹ a² and the front part at thus forming a guide for the back
part d' of the shoot or bolt D.
I prefer for the front part d² of the shoot or bolt D to be guided in the hole el
which is formed near one end of the roundabout E this part of the roundabout
being turned inwardly from the top so as to serve the purpose of the usual front
ear which guides the front part of the shoot or bolt thus rendering such front ear
unnecessary. Or instead of the front part d² of the shoot or bolt being guided by
the hole e near the end of the roundabout E the usual front ear fixed to the
bottom plate or cheek B or other means may be employed for guiding the front
part d' of the shoot or bolt. I wish it to be understood that I do not make any
claim to the use of the roundabout E made with the hole e¹ for guiding the front
part d² of the shoot or bolt D as I am aware that prior to this invention padlocks
have been made with their roundabouts constructed in this way.
It will be evident that instead of the combined tumbler and guide A being
pivotted on a pin C below the shoot or bolt D as hereinbefore described and
illustrated in Figures 1, 2 and 4 this combined tumbler and guide A may be
pivotted on a similar pin above the shoot or bolt D when the combined tumbler
and guide A will have the form represented by Figure 5.
The extreme back end of the shoot or bolt D is made with a front projection d³
to take against the combined tumbler and guide A when the shoot or bolt is shot
forward and thus prevent the shoot or bolt being shot forward too far. The shoot
or bolt D is prevented from moving too far back by its projection d* taking against
the back projection a' of the tumbler as shewn in Figure 2.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In padlocks constructing the tumbler so as to also form a guide for the back
part of the shoot or bolt substantially as hereinbefore-set forth.
2. In a padlock and in combination with the shoot.or bolt thereof the employ-
ment of the tumbler A constructed substantially as herein before set forth, and
shewn so as to also form a guide for the back part of the shoot or bolt.
3. The manufacture use and sale, of padlocks provided with a tumbler such as. A
which also serves as a guide for the back part of the shoot or bolt substantially as
herein before set forth.
4. The combination and arrangement of parts forming the improved padlock
herein before described and illustrated by the accompanying drawing.
