page_text: FRANCES COOPER GROFFMAN, 40, Dunsmure Road, Stamford Hill, Dealer in
Portmanteau Materials, do hereby declare the nature of this invention to be as
follows:-
A double staple lever lock with two bolts, one on the top left side, and one on
the bottom of right side, so constructed, that by a half turn of the key both bolts
shoot at once into staples affixed to an outer plate which closes on a spring. The
spring in the act of unlocking, forces up this plate. This outer plate serves
instead of an ordinary hasp, and has on the reverse side two staples which when
closed drop into corresponding slots in the inner plate which covers the box that
contains the levers. These levers act independently of, but in unison with, each
other. The key is of a duplex character but has only one pipe; on each side of
the pipe are the steps which when inserted in the key-hole, by a half twist only;
raises the levers simultaneously and shoots both bolts at once.
I, FRANCES COOPER GROFFMAN, of 40, Dunsmure Road, Stamford Hill, London, N.,
Married Woman, 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 locks which are especially applicable to trunks and
the like. It consists of a lock provided with two oppositely operating bolts which
on the rotation of a key independently but simultaneously shoot into respective
lateral staples provided upon a hasp which is hinged to the lid and furnished with
a spring to facilitate its disengagement from the lock.
The invention is illustrated in the accompanying drawings in which,
Figure 1 is a front elevation of the lock.
Figure 2 is a similar view but with the front plate removed.
Figures 3 and 4 are respectively back and end views of the plate hasp.
Figures 5 and 6 are detail views of a locking bolt and lever tumbler respec-
tively.
Figure 7 shows the kind of key employed.
The bolts D I) of the lock may be operated in conjunction with the usual lever

page_text: tumbler mechanism as shown, enclosed in a box A screwed to a front plate B,
which is furnished with key hole C and with slots C C for the reception of
staples E E on the plate hasp F. This plate hasp is hinged to a foundation plate G
screwed to the lid of the trunk, a spring H disengaging the plate hasp from the
lock when the bolts are withdrawn from the staples E E.
When it is desired to fasten a trunk the plate hasp F is pressed against the
plate B the staples E E entering the slots C C therein. The key is then inserted
and turned and the bolts D D are simultaneously shot into engagement with the
staples.
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: :―
1, In a lock for trunks and the like the combination of a plate hasp, hinged
to the lid of the trunk with a lock having oppositely operating bolts which engage
with respective lateral staples on said hasp as hereinbefore described with refer-
ence to the accompanying drawings.
2, The improved lock and fittings for application to trunks and the like as
herein before described with reference to the accompanying drawings.
Dated this 2nd February 1898.
