Improvements in Bag LOCKS.
I, JOHN BOULTBEE BROOKS, of Criterion Works, Great Charles Street,
Birmingham in the County of Warwick Manufacturer do hereby declare the
nature of this invention to be as follows:
My invention relates to locks for such bags as have two openings, one on each
side of the frame. Hitherto, such bags have had two locks, thereby necessitating
a very wide frame.
In carrying out my invention, I make the lock in the form of a rectangular
shaped box, the top plate of which carries an upwardly directed nozzle having a
keyhole in its centre, and two pushers, one on each side of the keyhole. In each
of the two sides of the lock I make a pair of staple gaps to admit the staples; and
inside the lock I place two catch plates, each carrying a pair of catches which
The catch plates are pressed upwards
come opposite their respective staple gaps.
by suitable springs, to keep the catches engaged with the staples, & may be pressed
down, to release the staples, by the before mentioned pushers which project
upward through the nozzle of the lock.
The locking action is by a sliding plate, actuated by a key & controlled by a
spring; the plate carries projecting stops, which when the bag is locked prevent
the pushers & catch plates from being pressed down.
The two catch plates and their pushers work quite independently of each other,
except that the one locking action locks both of them.
To enable the lock to be made narrow, I do not place the staple gaps (& catches)
on the respective sides of the lock directly opposite to each other; but I place
them alternately, so that the two pairs of staples entering from the contrary sides
its pushers & keyhole are
of the lock pass each other side by side. The nozzle
also placed obliquely across the lock.
Each end of the lock is provided with a lug for fixing to the centre web of the
bag frame, a piece of which is cut away to admit the lock, which may be further
provided with means for fixing to the upper part or cap of the frame.
Dated this 17th day of July 1894.

Improvements in Bag LOCKS.
I, JOHN BOULTBEE BROOKS of Great Charles Street, in the City of
Birmingham, 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 has relation to the locks of bags, such as have two openings 'or
two entrances and located upon two sides of the frame respectively; heretofore,
such bags have been fitted with two independent locks, one for each side or each
opening, whereby a very wide frame is necessitated to carry such two locks or

page_text: My invention consists in employing a single lock for the locking and fastening
of both sides of the bag, and in making the said single lock, double locking and
double fastening.
Thus a single lock has contained within itself double locking mechanism, which
both locks and catches the sides to the middle part of the frame.
In carrying out my invention, both the lock and catch mechanism which are enclosed
within a rectangular shaped casing or box, consists of rising and falling catch
plates (normally kept up by springs) having pusher posts directed upwards from
their top sides, and taking through' guide holes of a nozzle passing through and
standing above the surface of the middle cap or middle frame, and with a keyhole
through the middle of the said nozzle down which a key passes for gaining access
to a single shoot or sliding plate. This said sliding plate has locking posts which,
are, by its traverse, made to come opposite to or before solid parts of the catch
plates, whose catches come in front of staple holes formed in the casing, and into
which, staple plates carried upon the opposite framings or inner caps, 'pass.
Thus it will be seen that the catch plates, which are in duplicate, are locked-by
a single traversing and sliding plate, kept home by a spring.
Figure 1 of the accompanying drawing represents partly in vertical section and
partly in elevation, a bag, opening upon its two opposite sides, and with a single
lock for catching and fastening the same, and constructed and arranged according
to my invention. The parts of the lock are shown in the position which they
assume, when the sides of the bag are secured by the catches only.
Figure 2 represents a vertical section upon the dotted line of the said bag
frame Figure 1, but with the side frames or inner caps, opened.
Figure 3 represents a topside plan of a portion of Figure 1, showing the
disposition of the nozzle and the pushers, relative to the keyhole.
Figure 4 represents a topside plan of a part of Figure 2, with the lock casing
horizontally broken into, so as to exhibit the double catch plates, with their catches
and pushers, and the pair of locking' posts, carried by a single shoot or sliding
plate.
Figure 5 represents a like sectional view of the lock or middle part of Figure 4
but with the shoot or sliding plate, shot, so as to bring its posts non-coincident
with the gaps of the catch plates, which are simultaneously locked by such
movement.
Figure 6 represents a like view as Figure 5, but with the catch plates and
casing removed.
Figure 7 represents a plan and side elevation of one of the catch plates,
separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is the middle cap or middle frame part carrying the casing or box part b,
containing both the catch and lock mechanism, consisting of a pair of rising and
falling catch plates c, c', having hollow pushers c³, c³, passing through holes b', of a
sleeve or nozzle, directed from the top of the casing b, whose top, bottom and
sides 6, 64, and 6, enclose the catch and lock mechanism.
The casing b, has brackets or "lugs 6, for securing the said casing by rivetting
or otherwise to the cap or middle framing a, through its web a'. Each of the
sliding catch plates besides carrying a pusher also carry a pair of 'inclined
catches c, which come opposite staple gaps 6, made through the opposite sides of
the casing b, and wherethrough the staple plates d², of the side framing parts or
inner caps, take.
Located within the hollows or axial holes' c'; of the pushers ; care leoiled
springs with the lower ends of them abutting upon stalks g, carried by the
lock casing and upon which stalks' the pushers and catch plates slide. The shoot
or sliding plate 9, has locking notches 9; 9; at one end, into which the free and
ribbed end g', of a spring g', alternately takes, for retaining the slider with its
posts 9, 9', in its locked and unlocked positions.

page_text: Each of the catch plates have gaps c, which when the lock is unfastened, are
coincident with the posts 98, 9', but when the bag is fastened, the said parts have
presented in front of them, solid parts of the catch plates, as best seen and
represented in Figure 5.
Now the middle of the nozzle or sleeve has a keyhole 8, whilst the shoot or
sliding plate g, has a suitable gap 98, for the bit of an introduced key to take within
for the shooting of the same.
It will be seen that the staple gaps 67, are out of line one with another, that is
to say, they are placed alternately, so that the two pairs of staples, entering from
the contrary sides of the lack casing, are clear of each other and lie edge to edge,
whilst the nozzle or sleeve for carrying the pushers and in which the keyhole is
made, is disposed obliquely across the lock bence compactness.
OPERATION.
Assuming that the bag is locked and that either one side or the other is required
to be opened, insert the key in the lock and rotate it, so as to throw the shoot or
sliding plate for unlocking, then to open the side of the bag, depress the pusher c³,
when the catches c', will be taken from the staple plates and the side opened. The
opening of the other side e, is performed exactly in the same manner as the opening
of the side f, but by pressing the pusher c³.
When the two sides are closed, the simultaneous locking of the same is
performed by the throwing of the bolt back, so as to bring the posts under the
ungapped or uncut away parts of the catch plates.
Although the openings or entrances of the bag may lead to a common body, yet
they may if desired lead to sides or divisional body parts.
Having now particularly described and ascertained the nature of my said inven-
tim, and in what manner the same is to be performed, I declare that what I
claim is :-
First. In locks for bags having two openings or entrances, the simultaneous
locking of the duplicate catch and pusher plates c, c', by the throwing of a single
shoot or sliding plate, operated by a single key, substantially as described and
set forth.
Secondly. In locks for bags having two openings or entrances, combining with
a lock casing and shoot or sliding plate, a pair of independently operated pushers
carried by independent catch plates, fitted with springs and having other accessories,
substantially as and for the purpose as described and set forth.
Thirdly. The improvements in bag locks, and the construction, arrangement
and combination of the parts of the same for the purpose as described and
set forth.
