IMPROVE- MENTS IN LOCKS.
Year: 1884

page_text: J, CHARLES FERDINAND VEIT of 28 Bartlett's Buildings in the City of London,
Commission Agent do hereby declare the nature of my invention for IMPROVE-
MENTS IN LOCKS. to be as follows:-
This invention relates more particularly to locks for bags and other articles in
which a catch in addition to a locking bolt is used, but part of the invention is
applicable as an ordinary lock.
In carrying out my invention I pivot to the lock plate a tumbling lever, one end
of which is formed with a catch and the other end projects through the plate and
is, rivetted, brazed or otherwise rigidly secured to a ring or other handle by which
the lever can be rocked on its pivot. In the normal position this ring will lie
against the lock plate. On the underside of the lever is a catch between which
and the plate a locking bolt enters, so that the tumbling lever cau be locked in the
norinal position.
The locking bolt is formed of a three cornered plate of thin metal the corners of
which are bent downwards at right angles to the body of the plate and outwards
parallel with the plate, one of these outwardly beat portions forming the bolt
proper. This plate is mounted on a stud which projects downwards from the
underside of a spring bridge piece. This piece is secured by both ends to the lock
plate.
The stud projects through a key hole formed in the plate and serves as the guide
pin for the key.
On the underside of the bolt plate is inserted a pin against which the key strikes
to turn the plate or shoot the bolt and this pin is so arranged that as soon as the
bolt is shot the key will slip over it.
This arrangement of lock or locking bolt obviates the use of springs which form
the weak points in all cheap locks.
This part of the invention is applicable as an ordinary lock of cheap form the
only change required being to make the bolt proper somewhat longer than when
used, to lock the lever catch.
Dated this 20th day of December 1884.

I, CHARLES FERDINAND VEIT of 28 Bartlett's Buildings. in the City of London,
Commission Agent 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 more particularly to locks for bags and other articles in
which a catch and a locking bolt are used, but part of the invention is also
applicable as a lock for doors and other places, in which cheapness and durability
are combined.
My improved lock for drawers, satchels, pocket-books, sewing machine cases, and
other articles, consists in the combination with a lock plate having lugs projecting
from the inner surface thereof, of, a pivot secured in the lugs, a hook swinging on
the pivot, an arm or handle projecting from the hook through the lock plate, a stop
or catch projecting from said arm, and a locking bolt which co-operates with said
stop or catch, and serves to retain the hook in its locked position.
In the accompanying Drawing,
Fig. 1 represents a sectional side view. of a drawer provided with my lock, the
drawer being open.
Fig. 2 is a vertical section of the same closed and locked.
Fig. 3 is a front view of the same.
Fig. 4 is an inside view of the lock detached.
A is the lock plate, from the inner surface of which project two lugs A¹ which
form the bearings for a pivot B. On this pivot swings the book C, from which.
extends an arm or handle C' through the lock plate. In the example shown in the
drawing, the arm or handle C' is made in the form of a ring, but it may be made
in any form suitable for the purpose. The arm C' is provided on its underside
with a stop D, which, when the hook is brought in its locking position as shown in
Fig. 2, is situated inside of the lock plate, in position to co-operate with a bolt b¹,
forming part of a lock arrangement hereafter more particularly described. This
bolt swings on a pin c, and a revolving motion is imparted to it by a key, but a
bolt may be used which has a reciprocating motion. When the hook C is in its
locking position, and the bolt &¹ is moved into the position shown in Figs. 2 and 4,
it engages with the stop D, and retains the hook in the locked position. Before
the hook can be moved to the unlocked position (Fig. 1), the bolt must be thrown
back out of the path of the stop D. In one of the lugs A¹ are two holes E E',
arranged in the arc of a circle of which the pivot B is the centre, and on one side
of the hook is formed a rounded projection F, which engages with one or other of
the the holes E E¹, and retains the hook in its locked or unlocked position, the
elasticity of the metal being sufficient to ensure this result.
By referring to Fig. 2, it will be seen that the drawer to which my lock is applied,
cannot be drawn out until the hook is moved into the position shown in Fig. 1.
But if my lock is applied to a fixed receptacle with a hinged top, said hinged top
is locked by the hook C, and it cannot be raised until the hook is moved to the
unlocked position.

page_text: From these examples it will be readily understood that my lock can be applied
to frames of travelling bags, satchels, and pocket books, also to trunks, sewing
machine cases, and other articles.
In my improved locking bolt I am enabled to dispense with all springs or weights,
parts which, in cheap locks, cause endless trouble.
This part of my invention is also applicable for locks of various kinds for doors
and other places, such as mortise locks and, box locks.
Figs. 5 to 8 show the mode of constructing a single lock suitable for a drawer or
bag, and Figs. 9 to 12 à double lock suitable for a door. Fig. 5 is a plan view of
the single lock with the front plate removed and the case in section. Fig. 6 is a
side elevation, partly in section, and Figs. 7 and 8 are respectively a plan view and
edge view of the front plate. Fig. 9 is a plan view of the double lock with the
front plate removed and the case in section. Fig. 10 is a side view, partly in
section, and Fig. 11 is a view of the front of the case, and Fig. 12 is a plan view
of the metal blank forming the bolt and tumbler displayed-I will first proceed to
describe the double lock.
a a represent the metal case of the lock, which may be cast or stamped out from
a sheet of metal, as preferred. b is a tumbler, or an equivalent for the same, which
is formed in one with the bolt, and consists preferably of a disc with lateral
ears or projections. The tumbler b with the bolt blank b' is stamped out of a sheet
of metal, as seen in Fig. 12, which shows the metal for the tumbler and bolt
displayed.
To form the bolt, the blank b¹ is folded down twice on itself on the dotted lines,
so as to form three thicknesses of metal.
The ears or projectious 62 are bent downwards at right angles to the part Ù, to
form legs on which the tumbler rests on one side, and the ears or projections b³ are
bent upwards at right angles to the part b to form legs on the other side, on which
the tumbler rests, as seen in Figs. 9 and 10. In the single lock, the legs b³ will be
dispensed with, see Figs. 5 and 6, the key being inserted from one side only.
A central hole is pierced in the tumbler 6, in which is secured, by brazing or
otherwise, a pin c.
This pin c serves as the guide pin for the barrel of the key. The front d of the
case is of thin metal, and is slightly rounded or bowed (see Fig. 8), so that when
the tumbler b is in position in the case, and the front d is placed thereon and
sécured by screws or rivets, it will bear with some considerable pressure on the
tumbler, and the friction thus obtained will prevent the tumbler rotating without
the use of a key.
•
The rotation of the tunibler is caused by the key striking against a pin or pro-
jection e fitted to the tumbler b, and of such a depth that the key will slip past it
when the movement of the tumbler is arrested by a fixed stop e' suitably placed
for the purpose.
The front d, by reason of the thinness of the metal, will give
sufficiently to allow of the key passing the pin e, so that the key may be with-
drawn from the lock. It will however be evident that the key may be withdrawn
from the lock by turning it in the opposite direction, after the bolt is raised.
The tumbler is maintained in its proper position in the case by means of a
groove ƒ formed in the bottom of the box or case, and in which the legs b² of the
tumbler enter and work. The legs are maintained in the grooves by the pressure
of the front d as before explained.
The amount of motion to be given to the tumbler or disc b may be determined
by means of the holes g, g, in the spring plate d, into which holes either a prolonga-
tion of the pin e (see Fig. 6), or a projection g¹ on the end of a leg b³, see Fig. 9,
may enter.
In the single lock the pin c is secured to the front or spring plate d (see Fig. 8),
and serves not only as the guide pin for the key, but also as the pivot pin on which
the tumbler rotates. The rotation of the tumbler in the single lock is effected in
the same manner as in the double lock.

page_text: The pressure of the plate d on the tumbler will be sufficient to hold the tumbler
against any amount of shaking, but it is possible, on applying pressure to the outer
end of the bolt 1, to push it back. In order to prevent this, and thus ensure a
perfect locking when the bolt is shot, I employ any suitable locking device, which
will be arranged to slip over the bolt when it is shot, and be capable of being raised
by the turning of the key in the lock when it is required to withdraw the bolt.
In the drawing I have shown a convenient form of locking device as applied to
both single and double locks. This device consists of a notched plate h, which is
rivetted or otherwise secured in the case, and is formed with a lateral projection or
projections ¹, one or both of which, when bent at right angles to the plate h, will
project under or over the tumbler b, as seen in Figs. 5 and 9. The front edges of
these projections h¹ are bent to a cám shape, as seen at Figs. 6 & 10, so that as the
key passes round, these projections will be raised, and with them the notched
plate h, sufficiently to allow the bolt 61 to be withdrawn. When the key passes
away from the end of the projection h³, the notched plate h will be held up by the
bolt b. When the bolt is again shot, the notched plate will resume its normal
position, being influenced thereto by the tongue d¹ cut froin the spring plate d, and
which presses against the edge of the plate h, see Figs. 6, 7 and 10, 11.-Fig. 13
shows the shape of piece of metal from which this locking device will be formed.
This locking device is unnecessary in the bag lock, the construction of which, on
account of its small size, will be slightly modified from that described above. The
exact construction of this lock will however be clearly understood on reference to
Figs. 1, 2 and 4, with the assistance of the above description.
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. A lock for satchels, drawers, pocket books and other articles, constructed and
arranged substantially as herein shown and described with reference to Figs. 1 to 4.
2. In a lock for satchels, drawers and other articles, the combination with a hook
provided with an arm or handle, and a stop or catch, and mounted on a pivot
carried by lugs secured to the lock plate, of a locking bolt arranged to co-operate
with the said stop or catch for the purpose set forth.
3. The construction of a springless lock for doors and other places substantially
as herein shown and described with reference to Figs. 5 to 13 of the drawings.
4. In a lock for doors and other places, the combination of a rotating tumbler
formed in one piece with a bolt, and having legs or projections, with a spring plate
which is firmly secured to the case or box, all substantially as and for the purpose
set forth.
