PROVISIONAL SPECIFICATION.
Improvements in Bar Locks for Trunks.
.
°
I, JOSEPH LEGGE of Stafford Street Willenhall, in the County of Stafford
Lock Manufacturer do hereby declare the nature of this invention to be as
follows:
My invention relates to those looks for trunks which are known as bar locks or
triple locks and which provide two or three fastenings for the trunk lid which are in
some way inter-dependent by means of rods.
My invention consists mainly of a triple hasp in which three separate hasps are
swivelled to and depend from a suitable plate which maintains the due interval
between them. And of a triple lock in which the three locks are held at due
intervals from each other (which intervals correspond with those between the hasps)
by forming part of one plate.
Between the three locks, there are thus two intervals each bridged by a strip of
metal forming part of the metal of the lock bodies. These two strips of metal
I channel longitudinally from lock to lock in such a manner that they receive
the rod or rods which actuate the three locks and protect them from injury.
In order to strengthen the triple hasp above described and also with a view to
enhancing its appearance, I shapo the metal plate on which the hasps swivel to
correspond with the channelled parts of the lock already referred to.
My invention thus makes it possible to apply a triple hasp in one piece to a
trunk lid, and a triple lock in one piece to the body instead of applying. three
separate hasps as is now done and three separate locks having also rods more or
less separate.
My invention is obviously applicable to double and quadruple looks no less than
to triple or bar locks. In fact there is no limit except convenience to the number
of locks I may treat in the above manner. And I can apply my invention to any
kind of bar-lock whatever may be its mechanism.

I, JOSEPH LEGGE, of Stafford Street, Willenhall. in the County of Stafford,
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 invention relates to those locks for trunks which are known as bar locks, and
which when three fastenings are used are frequently known as triple locks, and
which provide two or three fastenings for the trunk lid, which are interdependent
in a greater or less degree, by means of a rod or rods.
These locks as heretofore constructed have the cases, and also the hinge plates
for the basps, formed each separately from one another. Considerable care has to
be exercised, therefore, in spacing the cases apart from one another at the front of
the trunk body and in spacing the haeps apart on the lid.
...:

page_text: According to this invention, both or all the portions of a bar lock into which the
hasps close are formed in one piece of sheet metal with one another, being joined
one to another by a strip of metal, formed of a hollow shape to allow of the passage
of a rod therethrough of which the outer end engages with the link of a hasp to
fasten the haep down. The whole casing for the two fastenings, or set of fastenings,
by which the hasps are held down, is thus made in one piece of sheet metal. The
basps also of the lock are swivelled to, and depend from, a single plate which maintains
the proper interval or intervals between them. This plate to which the basps are
swivelled is conveniently formed with a longitudinal channel, for the sake of strength
and appearance.
In order that the invention may be readily understood, I will proceed to describe
the same with reference to the accompanying drawings as applied, by way of
example, to a triple lock.
Figure 1 is a front elevation of the complete lock, the lower portions of the
middle and one of the side basps being broken away for convenience of illustration,
and shows also a portion of the lid and body of a trunk; Figure 2 is a plan
thereof;
Figure 3 is an inside view of the portion of the lock which is fixed, when in use, to
the body of a trunk ;
Figure 4 is a vertical section taken on line æ æ of Figure 1; and
Figure 5 is a detached transverse section through the case of one of the end
fastenings, taken on line y y of Figure 3.
The central lock case A into which the central hasp A closes, is formed in
one piece of sheet metal with the side cases B into which the two side hasps B
close, by means of connecting lengths C. These connecting lengths are formed of
a channel section, as shewn by Figure 4, which is opon at the back, and the
rods a which interlock with the hasps B₁ pass, respectively, from the contral
case A along the inside of the connecting lengths, as shewn by Figures 3 and 4,
to the side cases B. The lock mechanism, including the rods (or a single rod if
such is used, as is sometimes the case, with this class of lock, to lock all the basps)
may be of any ordinary or convenient description, the particular form of
mechanism not being an essential feature of the invention. The combined
sheet metal casing formed of the parts lettered A B and C is conveniently fixed
to the front of a trunk F by means of bults b, which pass through flat portions
or ears of the sheet metal casing which bed against the flat surface of the
trunk,
! .
The hinge plates D for the hasps are formed together in one piece of sheet
metal, being joined by connecting pieces E. These connecting pieces are formed
to a channel shape in transverse section, as shewn by Figure 4, and such formation
is continued across the central plate and for a considerable distance along the upper
portion of each side plate, as shown. This channel formation gives considerable
strength to the combination, besides enhancing its appearance. The combined
hinge plates Dand. connecting pieces E are conveniently fixed to the front of the
trunk lid G by means of bolts e, which pass through flat portions of the hinge
plates which bed against the surface of the trunk lid.
.
It will be seen that, according to this invention, a triple lock and a triple-hasp
are each applied as a whole or single device to the body and lid of a trunk,
respectively, instead of being applied as three separate locks with their rods or rod
more or less separate also, and three separate hasps, as is necessary in the cuse of
triple locks of the ordinary construction.
It will be obvious, also, that the invention is applicable to double and quadruple
locks as well as to triple bar.locks, and that there is no limit, except convenience,
to the number of bar loek fastenings, forming a set for a trunk, which may be
treated in the above manner. The application of the invention to other bar locks,
besides triple locks only, will now be sufficiently obvious, without need for further
description or illustration..
"
It is much preferred to form the combined lock cases and their connecting

page_text: lengths in one piece of sheet metal, that is to say from a single sheet metal blank,
and to form the hinge plates for the hasps and their connecting pieces also in one
piece of sheet metal, that is to say from a single sheet metal blank; but it will, of
course, be obvious that the purpose of the invention may be attained in some degree
by brazing or otherwise fixing together the lock cases aud connecting length
or lengths, and also the hinge plates and connecting piece or pieces, as in such case
also the combined lock and the set of hasps may each be applied as a whole
or single device, as described.
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 :-
:-
1. A bar lock for a trunk having the cases into which the hasps close permanently
joined together by a connecting length or lengths, so that the parts for affixture to
the trunk body may be fixed as a whole or single device, substantially as described.
2. A bar lock for a trunk having the hinge plates for the hasps permanently
joined together by a connecting piece or pieces, so that the set of plates may be
fixed as a whole or single device, substantially as described.
3. A bar lock for a trunk having the cases into which the basps close and a
portion or portions which connect them with one another formed together in one
piece of sheet metal, that is to say, from a single sheet metal blank, substantially
as described.
4. A bar lock for a trunk having the hinge plates for the hasps and a connecting
piece, or connecting pieces, formed in one piece of sheet metal, that is to say from a
single sheet metal blank, substantially as described.
5. A bar lock for a trunk constructed substantially as described and shown by
the drawings herewith.
