PROVISIONAL SPECIFICATION.
Improvements in Padlocks.
I, HENRY MOORE, of 4 Sydney House, Latona Road, Glengall Road, Peckham,
Surrey, Locksmith, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a novel method of manufacturing or constructing
padlocks.
For the purpose of my invention, I dispense with the usual shackle or two half
shackles and substitute therefore, a bolt which has a free movement by the hand for
passing through the staple or hasp and when pushed home a spring bolt moving at
right angles, shoots into an annular groove formed in the first named bolt and locks
the appliance.
The spring or locking bolt is actunted for opening or unlocking purposes by a
lever, which through the intermediation of another lever is operated by a key from
the outside.
The first named bolt works at right angles and is enclosed by a casing and the
inner end of it when said bolt is shot home presses against a spring buffer and puts
the spring in tension but the moment the locking bolt is released from the annular
groove, the spring buffer by its rebound shoots the first named bolt across and clear
of the opening, within which, the staple or hasp finds a lodgement, the padlock being
then free for removal.
Any system or number of tumblers can be arranged within the padlock to suit the
construction of the key for safety purposes.
When the padlock is applied to the staple or hasp it is only necessary to push the
first named bolt home or through the stable for the locking to become complete.

COMPLETE SPECIFICATION.
Improvements in Padlocks.
I, HENRY MOORE of 4 Sydney House, Latona Road, Glengall Road, Peckham,
Surrey, 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 a novel method of manufacturing or constructing
Padlocks.
For the purpose of my invention, I dispense with the usual shackle, or two half
shackles and substitute therefore a bolt which has a free movement by the hand for
passing through the staple or hasp and when pushed home a spring bolt moving at
right angles shoots into an annular groove formed in the first named bolt and locks
the appliance.
The spring or locking bolt is actuated for opening or unlocking purposes by a
lever, which through the intermediation of another lever is operated by a key from
the outside.
The first named bolt works at right angles and is enclosed by a casing and the
inner end of it when said bolt is shot home, presses against a spring buffer and puts
the spring in tension but the moment the locking bolt is released from the annular
groove, the spring buffer by its rebound shoots the first named bolt across and clear

page_text: of the opening, within which the staple or hasp finds a lodgement, the Padlock being
then free for removal.
Figures 1 and 2 of the annexed drawings clearly illustrate my invention as above
described, Figure 3 being a modified arrangement of the tumbler devices.
Figure 1 shows the Padlock with the bolt shot home and in a secure state.
Figure 2 shows the Padlock with the locking bolt drawn back and the locking
devices in the position after being acted on by the key.
A is the body of the Padlock containing the mechanism.
SLOCA Privo.
J tumblers.
K is a plate, seen more particularly at Figure 3, movable by the inner tumbler
when forced sideways by the key to bring the notch 6 directly under the pin c of the
spring locking bolt G, so that the pin c when said bolt G is drawn down by the action
lever H holds the plate K against its return by the tumbler spring, except when the
bolt E is pushed home, the locking bolt G being then free to rise into the groove a.
The plate K at this instant moves in the reverse direction for its solid edge to come
under the pin e to prevent fraudulent action on the bolt G.
According to the modified arrangement of mechanism, Figure 4, the spring bolt G
is acted on directly by the key for withdrawal from the annular groove in the bolt E,
the action lever H being dispensed with.
Any system or number of tumblers can be arranged within the Padlock to suit
the construction of the key for safety purposes.
When the Padlock is applied to the staple, or hasp it is only necessary to push the
bolt E home or through the staple for the locking to become complete.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The construction of Padlocks shown on the annexed drawings and as herein-
before described.
2. The construction of Padlocks with a solid upper part having a slot C, bolt E,
buffer F and spring bolt G arranged substantially in the manner described.
3. A Padlock having a bolt E with annular groove a for the reception of spring
locking bolt G, whether said spring bolt be moved by an action lever H. or directly
by a key, as described.
