Improvements in Fastenings for Travelling Trunks, Portmanteaux,
Cash and Deed Boxes, and other like articles.
We, JAMES STONE DUMBELL, Lock Manufacturer, of the Phoenix Lock and
Metal Works, Wolverhampton, in the County of Stafford, and ALBERT GEORGE
KIRBY, Works Manager, of 250 New Hampton Road East, Wolverhampton,
aforesaid, do hereby declare the nature of this invention to be as follows:-
Our invention relates to latch and similar fastenings for travelling trunks,
portmanteaux, cash and deed boxes, and other like articles.
The object of our invention is to construct such fastenings with their latching or
securing mechanism in combination with the ordinary locking arrangement of the
trunk, box, or other article, in such a manner that they can be more readily and
efficiently operated than with the combined locks and fastenings at present in
ordinary and general use.
In carrying our invention into effect we employ a central hasp and lock, or other
fastening, and secure same to the trunk, box, or other article, in the usual and
ordinary manner. On each side of this central lock or fastening, and at a convenient
distance from the same, we fix a hasp or other fastening plate to the lid, cover, or.
one portion of the trunk, box, or other article, and arrange that the securing or
fastening link attached to the hasp shall pass into a suitable casing fixed to the
body or to the other portion of the trunk or box in the usual manner.
To the back plate of the central lock or hasp securing casing of our improved
fastening we fix a pin or stud, and upon this pin or stud we mount two lever bolts.
The fulcrums or turning points of these lever bolts we arrange near to one end of
each, and the adjacent extreme ends (or short lever arms) are suitably formed to
enable them to embrace a lug or projection upon the hasp or the central lock in the
manner hereinafter described. The short arms of the lever bolts, also their fulcrums
or turning points, we preferably cover and conceal by the front or cover plate of
the lock, suitable slots or passages being formed in such plate for the projection of
the staple (when such is employed) and for the entrance of the lug or projection,
before described, upon the hasp. A suitable slot or passage is also provided in the
front plate for the lock key in the usual and ordinary manner.
The long arms of the lever bolts project from opposite sides of the central lock
casing and each is made of such length and form as to enable it to pass through a
suitably formed passage into the casings receiving the side hasps, or fastening
plates, hereinbefore described. The locking and unlocking of the central and the
two side hasps of our improved fastening is performed simultaneously by the simple
turning of a lock key. The action is as follows:-Beneath the pin or stud or the
fulcrum of the bolt levers herein before described, we place a sliding cam fitting
loosely between the two lever bolts and arranged in such manner that by means of
any ordinary and well known lock action of mechanism, the cam can be raised or
lowered (and kept at its upper or lower position) at will by the turning motion of
an ordinary lock key. When the cam is raised (the central and side hasps being
first pressed down into their respective casings,) the two ends of the short arms of
the lever bolts are caused to approach each other, and in so doing they embrace
the lug or projection herein before described upon the central hasp. The central
hasp is thus securely fastened. The raising of the cam also causes the ends of the
long arms of the lever bolts to move forward, and entering into the side hasp
casings to pass through the links attached to such hasps and thus to secure them in
the casings. In this manner the trunk, box, or other article is securely fastened at
three planee

page_text: To unfasten the trunk or box the key must first be turned in the reverse direction
to that required for fastening, when the sliding cam will be lowered and the lever
bolts released, and they can be then withdrawn, thus freeing or releasing the hasps
or fastening plates from their casings.
To assist in the speedy withdrawal of the lever bolts we sometimes employ
springs in the central casing arranged to act upon the bolts, and so cause them to
quickly follow the motion of the cam when the key is turned for unlocking.
Instead of securing the central hasp by causing the short arms of the lever bolts
to embrace a lug or projection in the manner hereinbefore described, we sometimes
fix a link or other equivalent to the hasp, and by causing the short arms of the
lever bolts to enter or pass through the same firmly secure it within the lock
casing.
We do not limit ourselves to any particular form or configuration of our lever
bolts, or of the hasps, hinged or sliding plates, and the cases for same, but
modify each or all of these parts to suit particular requirements, without departing
from the essential features of our invention.

COMPLETE SPECIFICATION.
Improvements in Fastenings for Travelling Trunks, Portmanteaux,
Cash and Deed Boxes, and other like articles.
We, JAMES STONE DUMBELL, Lock Manufacturer, of the Phoenix Lock and
Metal Works, Wolverhampton, in the County of Stafford, and ALBERT GEORGE
KIRBY, Works Manager, of 250 New Hampton Road East, Wolverhampton,
aforesaid, 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 :-
Our invention relates to latch and similar fastenings for travelling trunks,
portmanteaux, cash and deed boxes and other like articles.
The object of our invention is to construct such fastenings with their latching
or securing mechanism in combination with the ordinary locking arrangement of
the trunk, box, or other article, in such a manner that they can be more readily
and efficiently operated than with the combined locks and fastenings at present in
ordinary and general use.
In the accompanying sheet of explanatory drawings-
Figure 1 is an elevation of our improved fastening applied to a travelling trunk
or box, the locking arms or bolts being in their open position.
Figure 2 is a similar view showing the arms or bolts in their closed or locked
position.
Figure 3 is a plan of the central lock with the arms partly broken off.
Figure 4 is a detail elevation of the central sliding lock lever, and Figure is a
plan of the same.
Figures 6, 7, 8 and 9 are detail front and side elevations of the hasps.
Figure 10 is a front elevation of the fastening with hasps in position upon a
travelling trunk or box.
In carrying our invention into effect we employ a central hasp A and lock B, or
other fastening, and secure the same to the trunk, box, or other article C C', in the
usual and ordinary manner. On each side of this central lock or fastening, and at
a convenient distance from the saine, we fix a hasp or other fastening plate D D'
to the lid, cover, or one portion of the trunk, box, or other article, and arrange
that the securing or fastening link d attached to the hasp D or D' shall pass into
a suitable casing E E¹ fixed to the body C or to the other portion of the trunk or
box in the usual manner.

page_text: To the back plate of the central lock securing casing of our improved fastening
we fix a pin or stud F, and upon this pin or stud we mount two lever bolts G GI.
The fulcra or turning points of these lever bolts we arrange near to one end of
each, and the adjacent extreme ends, or short lever arms g g' are suitably formed
to enable them to embrace a lug or projection H upon the hasp A of the central
lock in the manner hereinafter described. The short arms 9 9 of the lever bolts,
also their fulcra or turning points, we preferably cover and conceal by the front
or cover plate B' of the lock, suitable slots or passages being formed in such
plate for the projection of the staple B2 (when such is employed) and for the
entrance of the lug or projection, before described, upon the hasp. A suitable
slot or passage is also provided in the front plate B₁ for the lock key in the usual
and ordinary manner.
The long arms of the lever bolts G G project from opposite sides of the central
lock casing B¹ and each is made of such length and form as to enable it to pass
through a suitably formed hole or passage e or into the casing E or E' receiving
the side hasps, or fastening plates, herein before described. The locking and
unlocking of the central hasp A and the two side hasps D D' of our improved
fastening is performed simultaneously by the simple turning of a lock key. The
action is
as follows Beneath the pin or stud or the fulcrum F of the bolt
levers G G¹ herein before described, we place a sliding cam K fitting loosely
between the two lever bolts and arranged in such manner that by means of any
ordinary and well known lock action or mechanism, the cam can be raised or
lowered, or sent forward or backward, and kept at its upper or lower or at its in or
out position at will, by the turning motion of an ordinary lock key. When the
cam surfaces R R' formed upon the levers G G₁ are raised (the central and side
hasps A D D' being first pressed down into their respective casings) the two ends
of the short arms g g¹ of the lever bolts are caused to approach each other, and in
so doing they embrace the lug or projection H herein before described upon the
central hasp. The central hasp is thus securely fastened. The raising of the
cam surfaces by the sliding movement of the cam K also causes the ends of
the long arms of the lever bolts G G₁ to move forward, and entering into the side
hasp casings E E¹ to pass through the links d attached to such hasps and thus to
secure them in the casings E, E¹. In this manner the trunk box or other article
is securely fastened at three places as shown in Figure 2.
To unfasten the trunk or box the key must be turned in the reverse direction to
that required for fastening, when the sliding cam K will permit the arms G G¹ to
be lowered and the lever bolts released; thus freeing or releasing the hasps or
fastening plates from their casings.
To assist in the speedy withdrawal of the lever bolts G G we sometimes employ
springs in the central casing arranged to act upon the bolts, and so cause them
to quickly follow the motion of the cam when the key is turned for unlocking.
Instead of securing the central hasp by causing the short arms of the lever bolts
to embrace a lug or projection in the manner hereinbefore described, we sometimes
fix a link or other equivalent to the hasp, and by causing the short arms of the
lever bolts to enter or pass through the same and firmly secure it within the lock
casing.
We do not limit ourselves to any particular form or configuration of our lever
bolts, or of the hasps, hinged or sliding plates, and the cases for same, but modify
each or all of these parts to suit particular requirements, without departing from
the essential features of our invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination and arrangement of fastenings for travelling boxes, trunks,
and the like, substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.

page_text: 2. The construction of fastenings for boxes, trunks, and the like, in which a
central lock operated by one key causes two pivoted arms or levers to lock two
end hasps or fastenings, substantially as herein before described and as illustrated
in the accompanying drawings.
3. The construction of fastenings for boxes, trunks and the like in which a
central lock and key controls two vibrating or pivoted arms such as G G¹ for the
purpose of causing them to lock or engage with two end hasps simultaneously
with their engagement with a central hasp, substantially as hereinbefore described
and as illustrated in the accompanying drawings.
4. In fastenings for trunks, boxes and the like, the construction and arrange-
ment of a pair of levers having smaller arms for embracing a central stud or
fastening paw or staple while the free or outer ends of the long levers engage with
and secure other fastening devices, substantially as hereinbefore described.
