IMPROVEMENTS IN SELF LOCKING PAD AND OTHER LOCKS
Year: 1884

page_text: I HERBERT PRICE LAVENDER of Cleveland Safe and Lock Works Wolverhampton
in the County of Stafford Managing Partner do hereby declare the nature of my
Invention for "IMPROVEMENTS IN SELF LOCKING PAD AND OTHER LOCKS "
as follows:-
to be
After constructing the case or frame of my lock in or after the usual manner
and so that one side or plate of it shall carry or support the mechanism I construct
and pivot the bow or shackle also after the manner of ordinary pad locks; that is,
as a single bow pivotted on one side or end only but also so formed and constructed
that when opened or unlocked a projecting arm or "limb" shall rise or project
from that part of the case which is under the bow, or shackle, when locked, or ;-
in other words-which is occupied by the loop or staple to which the lock, when
locked is attached; this projection then being forced, by the said loop or staple, to
become level or thereabout, with the case or rim of the lock and thus close the
shackle into the locked position.
In some cases I construct this projection as a separate limb, pivotted on the
opposite side of the case, to that of the hinge of the shackle, and arranged to act
by contact with, or pressure against, the prolonged internal part or "tail" of the
shackle; its office, in both cases, being to close the shackle into the locked position
by contact with or pressure against the staple or loop through or behind which
the shackle passes at the same time overcoming the spring which acts as the
reliever, to open the shackle, when the key has withdrawn (in unlocking) the bolt
and internal security or retaining parts, from their retaining or locked position ;
and it may be well to explain that as the closing of the shackle releases the bolt
and other internal security parts, from their unlocked to their locked position, the
complete locking is thus rendered automatic.
"
"
By preference I arrange the main bolt of these internal parts to work
longitudinally, that is, so that the pressure or thrust of the tail of the shackle
to prevent unlocking-shall act transversely of the bolt; and I increase the
strength of this by means of large "stumps or long slides or " runners upon
the main plate of the lock; and I employ "talons," levers stump lever-springs,
and the necessary internal details for securing the said main bolt after the manner-
so far as they are concerned-of other or ordinary locks.

page_text: COMPLETE SPECIFICATION.
I, HERBERT, PRICE LAVENDER, of Cleveland Safe and Lock Works, Wolverhampton,
in the County of Stafford, Managing Partner, do hereby declare the nature of my
Invention for "IMPROVEMENTS IN SELF-LOCKING 'PAD' AND OTHER LOCKS," and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
-
I first construct the case or frame of my lock, in or after the usual manner, and
so that one side or plate of it shall carry or support the mechanism, and I then
construct and pivot the bow or shackle, also after the manner of ordinary pad
locks; that is, as a single bow, pivotted on one side or end only, but also so
formed and constructed that when opened or unlocked, a projecting arm or "limb"
shall rise or project from that part of the case which is under the bow or shackle
when locked, or in other words, which is occupied by the loop or staple to which
the lock, when locked,-is attached; this projection then being forced by the
said loop or staple, to become level, or thereabout, with the case or rim of the lock,
and thus close the shackle into the locked position.
I prefer, generally, to construct this rising projection as a separate limb, pivotied
on the opposite side of the case, to that of the hinge of the shackle, and arranged
to act by contact with, or pressure against the prolonged internal part, or
"tail"
of the shackle; its office, in both cases, being to close the shackle into the locked
position, by contact with, or pressure against, the staple or loop, through or behind
which, the shackle passes; at the same time overcoming the spring which acts as
the reliever, to open the shackle, when the key has withdrawn,-in unlocking,—
the belt and internal security or retaining parts, from their retaining or locked
positions; and it may be well to explain that, as the closing of the shackle releases
the bolt and other internal security parts, from their unlocked, to their locked
positions, the complete locking is thus rendered automatic.
By preference, I arrange the " main bolt" of these internal parts to work
longitudinally, or so that the pressure or thrust of the tail of the shackle,-to
prevent unlocking, shall act transversely of the bolt; and I increase the strength
of this by means of large stumps, or long slides or "runners," upon the main plate
of the lock; and I employ "talons," levers, stump, lever springs, and the necessary
internal details for securing the said main bolt, after the manner,—so far as they
are concerned,-of other or ordinary locks.
In the accompanying illustrations Figure 1 is an internal face view of my
Invention, as a pad"
"lock, with the cap or front plate removed, and shown in
the locked position; and Figure 2 is the same in the unlocked position;-a. being
the plate or case of the lock; b the bow or shackle; c. the projecting arm or limb,
for closing the shackle, and locking the lock; d. the "tail" of the shackle, against
which c acts; e. the main bolt; f the talons; g. the levers; h the stump for ditto;
the lever springs, and k. the key pin or stump.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is-
- The general arrangement and construction of self-locking pad and other lock,
einbracing the parts or "limbs," and their positions and combined action, virtually
as, or after the manner herein before described and set forth.
