-
My improvements consist in the construction of Pad Locks for securing Bicycles,
Tricycles, Parcels Post Baskets and other purposes the features of novelty being
First, that of dispensing with shackles, and Second, that of also dispensing with the
ordinary kind of bolt shooting across the locks and being secured by a tumbler, thus
materially simplifying the same
In constructing locks according to my improved method 1 make them circular in
shape, and in about the centre of the cup or cise I employ a pin upon which a double
bitted hey revolves and immediately below and in a fine with this pin I fix a stump
upon which I employ two small levers working on either side the hey pin, each of
them baving a small hook which meet together above and in line with the key pin,
and the stump upon which they work On either side, and a little distance from these
levers, I employ another stump, upon each of which I place a spring which plays
against the back of each lever behind the hooks
Through the top of the cup or case I form a slot, and through this slot I pass the
end link of a piece of chain which I propose to use, and by forcing the link, which is
in contact with the heads of the hooks on the levers, and by virtue of their being
bevilled the pressure causes them to turn upon the stump, in doing which the hooks
recede from each other and allow the link to enter, when the pressure of the springs
forces them together again through the space in the link of the chain and thereby
secures it
The keyholes in the cap or cover of the lock are vertical, and by inserting the key
which has two bits in opposite directions, and turning it one fourth of a circle, the bits

page_text: are each brought in contact with the inner side of the lovers, which they cause to
recede and allow the drain to be removed, but in securing the chain to the lock no key
is required
I do not however strictly confine myself to the details herein described as they may
be open to some slight modification
Baskets, and other Analogous Purposes
I CHARLES HENRY PINSON of Moat Street Willenhall in the County of Stafford,
Pad 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
My improvements consist in the construction of Pad Locks for securing Bicycles,
Tricycles, Parcel Post Baskets, and other purposes the features of novelty being
First, that of dispensing with shackles, and Second, that of also dispensing with the
ordinary kind of bolt shooting across the loch and being secured by a tumbler, thus
materially simplifying the same
In constructing lochs according to my improved method I employ a pin-A-
Fig 1-upon which a double-bitted key revolves and immediately below and in a line
with this pin I employ a stump-B, upon which I employ two small levers-C C
working on either side the key pin, each of them having a small hook-A A which
meet together above and in line with the key pin, and the stump upon which they
work On either side, and little distance from those levers, 1 employ another
stump E E-apon each of which I place a spring-0-0-which plays against the
back of each lever behind the hooks
Through the top of the cup or case I form a slot, and through this slot I pass the
end link of piece of chain--F-which 1 propose to use, and by forcing the link,
which is in contact with the heads of the hooks on the levers, and by virtue of their
being bevilled, the pressure causes them to turn on the stump, in doing which the
hooks recede from each other and allow the link to enter, when the pressure of the
spring forces them together again through the space in the kink of the chain and
thereby secures it

page_text: The keyholes-G-Fig 2 in the cap or cover of the lock are vertical and by
inserting the key which has two bits in opposite directions, and turning it one fourth
of a circle the bits are each brought in contact with the inner side of the levers which
they cause to recede and allow the chain to be removed, but in securing the chain to
the lock no key is required The chain is continued from one link to the other as
shewn in dotted lines
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
-
•
The improved device for securing chains to Pad Locks by means of two bolts or
levers actuated by two springs and operated by double-bitted key substantially as
herein described and illustrated by the accompanying drawings
