IMPROVEMENTS IN PAD LOCKS
Year: 1887

We JOHN MARLIN of High Street West Bromwich, near Birmingham in the
County of Warwick, Ironmonger, and HENRY TAYLOR of 48 Summer Row
Birmingham in the County aforesaid Lock Manufacturer, carrying on business
together under the style of firm Marlin and Taylor at Sandwell Road West Bromwich,
do hereby declare the nature of our invention for "IMPROVEMENTS IN PAD LOCKS" to
be as follows:-
This invention has for its object that of dispensing with the ordinary shackles by
which Pad Locks are secured to staples upon doors, gates, boxes and for other
purposes, such ordinary shackles turning and working upon a pin passed through one
of the ears of the locks, and being secured by the bolts of the locks passing through
the spoons (as they are usually termed) on the other end of the shackle.
In constructing locks according to our improvement, we employ a bolt shooting
from left to right and vice versa across the lock plate and ears of the same in the act
of locking and unlocking, the head of the same being solid and of the same thickness
as the space between the caps or cover plates of the locks and the back-plates, and
being supported by a strong pillar in the latter plate, as well as by the rims of the
caps or cover plates, and also by the end of the bolt shooting into a recess in a solid
block on the left ear of the back-plate, whilst the tops of the ears across which
the head of the bolts pass are also solid, and when locked upon a staple, the head of
the bolt is entirely out of sight and protected from being in any way tampered
with.
Another important feature in our invention is that of affording additional security
by the introduction of what we preferably term a secret lever, one end of which grips
the bolt at the back of the head, whilst the other end nearest the pin upon which it
works passes through and is flush with the outside of the rim of the cap or cover-
plate.
This lever abuts against the end or ends of the other levers, and cannot be released
from its grip upon the bolt until they are raised by the key to their proper position so
as to admit of a stump on the bolt passing into the racks of the lever or levers in the

page_text: act of unlocking the same. When however it is so released and the bolt is shot back,
that end which grips the bolt gradually rises up an inclined surface at the back of the
solid head, and the other end in the rim of the cap or cover plate resumes its former
position and again abuts against the end of one or more of the levers having a recess
at the extreme end of the rack which falls upon the stump in the bolt therein and
holds it in an unlocked position, and when it is required to lock the same it may be
effected by pressing the back of the bolt head (which stands out from the body of the
lock) and the opposite ear together without the use of the key.
With the exception of the secret lover, the use of the other levers is old.

We, JOHN MARLIN, of High Street West Bromwich near Birmingham in the
County of Warwick, Ironmonger and HENRY TAYLOR of 48 Summer Row
Birmingham in the County aforesaid Lock Manufacturer, carrying on business
together under the style of firm Marlin and Taylor at Sandwell Road West
Bromwich 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 has for its object that of dispensing with the ordinary shackle by
which Pad Locks are secured to staples upon doors, gates, boxes, and for other
purposes, such ordinary shackle turning upon a pin passed through one of the cars of
the locks, and being secured by the bolts of the locks passing through the spoons-as
they are usually terined-on the other end of the shackle.
In constructing locks according to our improvements we employ a bolt-A-Fig. 1—
shooting from left to right and vice versa across the lock plate and the ears of the
same in the act of locking and unlocking, the head of the same being solid and of the
same thickness as the space between the caps or covers of the locks and the back-
plates and being supported by a strong pillar-B-in the latter plate as well as by the
rim of the cap or cover plate and also by the end of the bolt shooting into a
recess C in a solid block in the left ear of the back-plate, whilst the tops of the
ears D, D-across which the head of the bolts pass are also solid, and when locked
upon a staple, the head of the bolt is entirely out of sight and protected from being
in any way tampered with.
Another important feature in this invention is that of affording additional security
by the introduction of what we preferably term a secret lever-E-one end of which
grips the bolt at the back of the head-F-whilst the other end-G-nearest the pin
upon which it works passes through and is flush with the outer side of the rim of the
cap or cover plate.
This lever abuts against the end or ends of the other levers-H-and cannot be
released from its grip upon the bolt until they are raised by the key to their proper
positions so as to admit of a stump-I-on the bolt passing into the racks-J-of the
lever or levers in the act of unlocking the same.
When however it is so released and the bolt is shot back, that end which grips the
bolt gradually rises up an inclined surface-K-at the back of the solid head, and
the other end in the rim of the cap or cover plate resumes its former position and
again abuts against the end of one or more of the levers-H-having a recess at the
extreme end of the rack-J-which falls upon the stump-I-on the bolt therein and
holds it in an unlocked position, and when it is required to lock the same it
may be effected by pressing the back of the bolt head which stands out from the
body of the lock and the opposite ear together without the use of the key.

Insert the key and turn it to the right so as to raise the levers to their proper
height, when it will be found that the bolt is immoveable, but by pressing the end of
the left thumb or thumb nail against that part of the secret lever-G-which
passes through the rim of the cap or cover-plate, the said lever is released from
its grip upon the bolt, and by turning the key the latter is shot into an unlocked
position.
These locks however may be made as ordinary locks without the use of the secret
lever, and we desire it to be understood that there is nothing new in the use of the
other levers-H.

Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed we declare that what we
claim is,
1-Is that of the employment of a bolt in lieu of a shackle, substantially as herein
