Improvements in Locks and Fastenings for Bags.
I, JOHN BOULTBEE BROOKS of Great Charles Street in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows :-
My invention has for its object principally, to simplify the construction of, and to
render more convenient and efficient in use, bag locks, and fasteners, constituting the
fastening means of a bag frame.
I will first describe the lock part of the fastening means, which is secured to the
lock carrying or outer part of the frame.
The lock casing, which is secured to the inside of the side web, by attachment bars
or flanges, consists of a rectangular shaped box, with staple gaps, through its top
inner side, wherethrough the staple plates pass, for engaging with spring catches, or
inclined snugs, carried by the cross bar or frame of the pusher, which guided upon
vertically directed pins, encircled by springs. These said springs snap the catches
into the eyes of the staple plates, and take back the pusher after compression.
Directed axially within the middle of the pusher, which works within a pillar
sleeve, carried by the enclosing top plate of the lock casing, is a key-hole, with a peg
directed at some distance up its middle, from the lower side.
Situated and working on the side of the staple gaps, is a bolt, with twin upright
arms, directed to the height of the said staple gaps; so that when the lock is fastened,
the tops of the arms overlap portions of the staple gaps, and lie within side gaps of
staple plates, but when the lock is unfastened, the said bolt is shot back, and the
upright arms as aforesaid are removed from out of the side gaps in the staples, and
from before the staple gaps.
The bolt is retained in its locked and unlocked positions, by two V shaped recesses,
or holes made therein, and taking upon a like V shaped stud or projection, carried by
the framing. The bolt is kept up to the said V shaped projection, by the free end of
a flat spring.
The secondary fastening means which are situated respectively on the two opposite
sides of the lock, and at a short distance from the ends of the outer frame, consist of
an outside milled head or turn, with an inwardly directed flattened or elliptical stem,
which engages within a staple plate, whose eye is open on one side.
Thus, the staple plates which are carried upon the secondary part of the framing,
have eyes with narrow gates or entrances to them; so that when a bag is fastened,
the flat stems are turned at right angles to the frame, which then pass laterally through
the entrances into the eyes, which are there affixed, and the inner and outer frames
connected together near their ends, by turning the head, and bringing the longer
directions of the stems across the entrances as aforesaid.
The milled head or turn of the flattened stem, is carried by an attachment plate or
other bag furniture.
From the above description, it will be seen that the stem, which is the fastener part
of the appliance, admits of passing into the eye, when in one position, and prevented
from coming out of the eye when in another position.
The connection of the milled head to the carrying frame or furniture, is made by
turning the edge of the one, over that of the other, or by connecting the one part to
the other in a swivelling manner, by a pin taking into an annular groove; or by a pin
or pins engaging within slots, terminated by shoulders, against which the said pin or
pins come as abutments or stops.
Dated this First day of March 1889.

Improvements in Locks and Fastenings for Bags.
1, 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 for its object principally the construction of, and to render more
convenient and efficient in use, bag locks and fasteners constituting the fastening
means of a bag frame.
I will first describe the lock part of the fastening means, which is secured to the
lock carrying or outer parts of the frame.
The lock casing, which is secured to the inside of the side web, by attachment bars
or flanges, consists of a rectangular shaped box, with staple gaps through its top inner
side, wherethrough the staple plates pass, for engaging with spring catches, or inclined
snugs, carried by the crossbar, or frame of the pusher, which is guided upon vertically
directed pegs encircled by springs.
These said springs, snap the catches into the eyes of the staple plates and take back
the pusher after compression.
Directed axially within the middle of the pusher, which works within a pillar sleeve,
carried by the enclosing plate of the lock casing, is a key hole, with a peg directed
some distance up its middle from the lower side.
Situated and working on the side of the staple gaps, is a bolt, with twin upright
arms, directed to the height of the said staple gaps; so that when the lock is fastened,
the tops of the arms overlap portions of the staple gaps and lie within side gaps, in the
staple plate, but when the lock is unfastened the said bolt is shot back, and the upright
arms as aforesaid, are removed from out of the side gaps in the staples, and from before
the staple gaps.
The bolt is retained in its locked and unlocked positions, by two V shaped recesses,
or holes made therein, and taking upon, a like V shaped stud or projection carried by
the framing.
The bolt is kept up to the said V shaped projection, by the free end of a flat
spring.
The secondary fastening means which are situated respectively on the two opposite
sides of the lock, and at a short distance from the ends of the outer frame, consist of
an outside milled head or turn, with an inwardly directed flattened or elliptical stem,
which engages within a staple plate, whose eye is open on one side.
Thus, the staple plates, which are carried upon the secondary part of the framing,
have eyes within narrow gates or entrances to them; so that when a bag is fastened,
the flat stems are turned at right angles to the frame, which then pass laterally
through the entrances into the eyes, which are there affixed, and the inner and outer
frames connected together near their ends, by turning the head and bringing the
longer directions of the stems across the entrances as aforesaid.
The milled head or turn of the flattened stem, is carried by an attachment plate or
other bag furniture.
From the above description, it will be seen that the stem, which is the fastener part
of the appliance, admits of passing into the eye, when in one position, and prevented
from coming out of the eye when in another position.
The connection of the milled head to the carrying frame or furniture, is made by
turning the edge of the one over that of the other or by connecting the one part to
the other in a swivelling manner by a pin taking into an annular groove, or by a
pin or pins, engaging within slots, terminated by shoulders, against which the said
pin or pins come as abutments or stops.
Figure 1 of the accompanying drawing, represents, in side elevation, a bag frame,
provided with fastening means, constructed and arranged according to my said
invention.

page_text: Figure 2 represents an end elevation of the same, whilst figure represents a
vertical section of the lock part of the fastening means, upon an enlarged scale; this
said fastener, is shown unfastened, or with the parts in the positions, which they
respectively occupy, when the frame is unlocked.
Figure 4, represents a transverse vertical section of the said fastener, upon the
dotted lines A B, figure 3, with the key removed.
Figure 5, represents a horizontal section of figure 3, upon the dotted lines C D.
Figure 6, is a like horizontal section as figure 5 but with the parts fastened.
Figure 7 shows a transverse vertical section alike unto figure 4, with the lock part
unfastened and the inner frame, carrying the staple plates, removed from its closed
position.
Figure 8 represents an end elevation of the pusher and pusher bar, with the
fastening catches upon its top side ends.
Figure 9 is a top side plan of figure 8, whilst figure 10 is a transverse section of
the lock fastener part, provided with a modified form of fastener-catch.
Figure 11 shows a section of the right-hand end of the bolt, which is provided at
its back with V shaped notches, wherein a fixed V shaped projection, on the carrying
framing, takes respectively.
Figure 12 represents an end elevation (with the bag frame in section) of one of the
supplementary fasteners in its fastening position.
Figure 13 is a vertical section of the same with the frame open and unfastened.
Figure 14 is a cross section of figure 13 on the dotted lines E F, figure 12.
Figure 15 is an horizontal section, looking upwards, of figure 13, taken on the
dotted lines G H.
The same letters of reference, indicate corresponding parts in the several figures of
the drawings.
a is the lock casing, carried by and secured to, the side web, (cut away) of the
outer frame ba² are staple gaps made through the said framing, and wherethrough
the staple plates c², of a staple c, carried by the inner framing a pass, for engaging
with spring catches or inclined snugs d³, carried by and on the top
of the cross-
coiled springs f, disposed between the bottom a³, of the frame a, and the said cross bar,
which has holes through it corresponding and coincident to, the pegs e.
side
The staple plates have catch holes c³, and locking side gaps c, wherein the latter,
upright arms g² of a sliding bolt g, engage, when the parts of the bag frame are
fastened, or are to be fastened.
The back of the bolt, is notched or ✓ recessed at two points g³ g4, wherein
a V shaped projection as, on the fixed framing a engages respectively, whilst the
said bolt is kept home to the said projection, and retained in a locked or unlocked
position, by the free end of a flat spring h, bearing upon the outside of the bolt,
opposite the said projection; so that the throwing of the bolt, by the key i, whose
stem passes through an axial hole up the middle of the pusher, causes the said bolt to
rise over the projection, and be retained in its locked or unlocked position, by its
engagement as aforesaid.
The pusher is encircled, and works within a sleeve or hollow guide, j, attached to,
and carried by the outer framing.
The closing of the bag frame, and the passing of the staple plates through the
staple gaps, causes their inclines c³ of the said plates, to impinge upon the inclines of
the catches, which being carried by the pusher bar, yiold, in obedience to the
pressure exerted and then on coming opposite the gaps c³, they snap into them and
automatically fasten the bag which is again released, by pressing downwardly the
pusher d, so as to take the tops of the catches or snugs below the staple plates, and
on the withdrawal of the staple, the pusher bar and catches resume their normal
positions, by the pressure of the coil springs disposed thereunder.
To lock the bag frame after fastening, as in figure 5, turn the key from right to
left when the bolt, moving in obedience to the pressure exerted causes the retained
end to rise over the projection a', which on coming opposite the other recess g*,

page_text: snaps into it, and retains the bolt in its shot position, with the tops of the arms g²,
engaging with the side gaps c' as in figure 6.
The unlocking of the frame, is performed by turning the key in an opposite
direction, which slides the bolt backwardly, takes the arms out of their gaps in the
staple plates, and places the projection a' into the recess g³ of the bolt as aforesaid.
The supplementary fastening means, disposed on the framing on the two opposite
sides of the lock part, and adapted for securing the ends of the frames, consists of a
milled head or turn k, with an inwardly directed and flattened stem or stalk ², which
engages within a gapped eye 12 13 of a staple plate 1, secured to the inner framing a',
so that when a bag is required to be fastened the milled head or turn k, is turned at
right angles to its fastening position, so as to bring its narrow part, lineable with
the gap, so that it can pass through the said gap and enter the eye in that direction,
as represented in the sectional plan figure 15.
Thus, to fasten the bag, turn the heads as aforesaid and close the parts of the
frame, when the stems of the fastening parts, be within the eyes of the staple plates,
which are retained therein, by rotating the said milled heads or turns through a
quarter of a circle, which brings the widened part of the stems, at right angles to
the gaps of the eyes of the staple plates, as represented in figures 12 and 14, and
when in this position, the end parts of the frame, are fastened, and remain so until
the narrow part of the stems lie in the direction of the gaps, as in figures 13 and 15.
The milled head or turn, with its stem, is carried by and upon an attachment
plate m, secured to the outer part of the bag framing, whilst the said turn and
stem, is prevented from moving other than through an assigned distance viz.-a
quarter of a rotation, by studs 3, taking within and through quadrant shaped
gaps m², (see figure 15) and with a collar, at the junction of its flattened stem
with the head, working within a circular hole m³, disposed mid way between the said
quadrant slots and further, the undersides of the quadrant slots, are enclosed by a
washer plate n, taking upon the ends of the pegs ³, which prevents the turn and
its stem from being disconnected from its attachment plate or bag frame, as the said
studs pass.
In the modification figure 10, the shoulders of the catches d³, carried upon the end
top side of the pusher bar d2 of the pusher d, are made undercut or inclined at d
which take upon a like incline or chamfering of the catch eyes c³, of the staple
plates c², of the staple c. By thus making the said shoulders undercut and the
adjacent side of the eye as aforesaid, chamfered, there is no liability for the fastening
to become disconnected as is common with square shouldered catches.
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
First A combined lock and catch bag fastener, locking the staple plate within
the staple gaps or holes of the framing, by the direct action of the bolt or arms
carried by it, taking into side gaps of the said staple plate, of the staples, and
which locking is effected, in manner substantially as described, and set forth in
figures 1 to 7.
Secondly-Retaining the locking or fastening bolt, of combined locking and
catch bag fasteners, in its locked, or unlocked positions, by a projection, or an inclined
sided projection, taking into like shaped recesses sunken within the back of the bolt,
and which said bolt, is kept up to the projection, by a spring, pressing upon its front,
substantially as described and set forth in figures 3, 5, 6, and 11.
ThirdlyThe construction, arrangement and combination of the parts, of a
combined lock and catch bag fastener, as herein described and set forth, whereby the
pusher is free, whether the bag be locked or unlocked substantially as set forth in
figures 1 to 7.
Fourthly Making the shoulders. of the catches of bag frame catch fasteners,
undercut, and also making the adjacent side of the catch eye of staple plates,
chamfered substantially as described and set forth in figure 10.

page_text: Fifthly Securing bag frames, or the ends of bag frames, by means of a
fastener, consisting of a head or turn, with a flattened sided stem, depending from
its underside, and which said stem is adapted to take within a gapped or open fronted
eye of a staple plate, substantially as set forth in figures 12 to 15.
Sixthly The combination with the gapped eyes 113, of staple plates 1, of a flat
fastening stem ², as set forth.
Seventhly The construction, arrangement and combination of the parts of bag
fasteners, as herein described and set forth in figures 12 to 14.
