Office of the Commissioners of Patents, with his Petition, on the 25th
November 1864 A communication from abroad by the Excelsior Lock.
Company, of New York, in the United States of America.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN HASP Locks," to be
as follows:-
This Invention relates, first, to a novel arrangement of hasp and lock
socket for preventing, any lateral movement injuriously affecting the internal
parts of such locks; and, secondly, in a novel construction of the lock itself.
In applying the hasp lock to a trunk, the part of the hasp below the hinge is
attached to the front of the trunk by a pivot, pin, or bolt, the upper end of
the hasp is formed into a circular box or case, which carries the working parts
of the lock. To receive this end of the hasp a circular metal socket is sunk
in the front part of the lid of the trunk, and securely attached thereto. This
metal socket has a flange which fits closely against the exterior of the lid ;
it is also provided with T-shaped lugs which project through the lid and
through like-shaped slots in a plate to be placed against the interior face of
the lid. When the lugs are inserted in the slots the plate is moved endwise,
and thus clamps the socket to the lid, after which the plate is secured in
position by screws. Hasps thus secured to the body of the trunk by a pivot,
and to the lid by a circular socket, will permit any strain or lateral movement

a ledge or cross bar having a series of
springs and short sliding pins or bolts. The outer surface of this ledge is of
an irregular shape, and abuts against an irregular-shaped projection (having
holes to correspond) formed on the inner face of a disc plate or cover. This
disc plate or cover is attached to the circular box of the hasp by an arbour
which projecting centrally through it carries at the extreme end a cross bar
or latch. The plate inside the lid which clamps the circular socket to the lid
is perforated with an oblong slot to allow this cross bar or latch to pass
through it when turned, so as to coincide with the slot. When the latch is
turned at right angles to this slot the holes in the disc plate will correspond
in position with the holes in the ledge of the circular case and the springs
beneath the pins fitted therein will be forced into the holes in the disc plate,
and lock the latch in this position. A key is provided for thrusting the sliding
pins into the box and clear of the disc plate or cover, and giving the requisite
axial motion to the cross bar or latch to lock or unlock the trunk.
In order to prevent the holes in the disc plate being choked up with dirt it
is provided with an escutcheon secured to it centrally by a pivot pin. This
escutcheon has a series of holes corresponding with the disc plate in number
and position, and a slight axial motion is given to the escutcheon by a spring
sunk in the disc plate to keep the corresponding holes out of line with each
other until they are brought into coincidence by the key.
