COMPLETE SPECIFICATION.
Improvements in Locks for Sacks, Bags, and the like.
I, THORVALD TAGE AGATHON HANSEN, of 9, Gamle Kongevej, Copenhagen,
Denmark, Civil Engineer, 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 to improvements in locks for sacks, bags or the like.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front view of the lock, and Fig. 2 a section at line A-B of Fig. 1
drawn at double the scale of Fig. 1.
b
The lock consists of a metal plate a provided with a pin or pivot 6 carrying
another plate lying flat upon the plate and arranged to turn round the
pivot b. The plate is on a part of its periphery provided with teeth d and,
for the purpose of being able to turn the plate round the pivot b, two lugs e are
projecting from its surface. Another part of the plate is cut away in such a
manner that a horn or nose f is formed which is bent somewhat upwards from
the plate a so that the eye o of a wire or string n may be easily passed over it.
On a pivot y fixed to the plate a lever his arranged, which fever can turn
round the pivot g and by means of a tooth i catch in between the teeth d of the
plate c. When the tooth is placed between two of the teeth it is kept in
position by means of a pink fixed on a spring attached to and lying on the
top of the lever h, the pin passing through a hole in the lever down into a
hole m in the plate a. The spring is provided with projections or lugs by
means of which it may easily be raised when the pink is to be disengaged
from the hole m in the plate a.
As will be seen from the drawing one end of a piece of wire or string n, long
enough to pass round the folded mouth of the sack, is attached to the plate a
whilst the other end terminates in an eye o which can be slipped onto the nose f.
When this has been effected the plate c is turned by means of the two lugs e,
the tooth having first been pulled out from between the teeth d.
By turning the plate the wire or string n will be tightened, and when the
proper tension has been attained the lever his turned downwards, until the
tooth catches in between two of the teeth d.
The tooth being in place, the pin k slips down into the hole m of the plate a,
the tooth i is fixed in its place and the sack is securely closed.
In order to guide the wire or string n, whilst the plate c is being turned, a
guide plate p is attached to the edge of the plate a at a suitable point.
When the sack is to be opened, the spring is raised and the lever is turned
outwardly so that the tooth is released from the teeth d. The plate c may
now be turned back until the eye o can be slipped off the nose f. In order that
the eye o may be more easily handled it may be supplied with a handle q.
Instead of the pink for holding the lever in a given position a wire passing

page_text: through holes in the lever and in the plate a may be used, the ends of the wire
being tied together and sealed by means of lead or sealing-wax, the lock may
be used for mail-bags, money-lags and the like..
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:
1st. A lock for sacks, bags, or the like, characterized by a plate a having a
pivot around which turns another plate c, provided along the edge with teeth d
and a nose f, the plate having also a movable lever with a tooth i, adapted
to engage between the teeth of the plate c, in combination with a wire or string
having one end attached to the plate a and its other end terminating in an eye o
which may be slipped over the nose f of the plate e after the wire or string has
been passed around the folded mouth of the sack or the like, substantially as
set forth.
2nd. In combination with the lever specified in the preceding claim, a spring
provided with a pink which, when the tooth of the lever is brought into gear
with the teeth of the plate e, enters into a hole m in the plate a, all substantially
as set forth.
3rd. In the lock specified in Claim 1, the lever h adapted to be held in a fixed
position by means of a wire which is sealed by lead or by sealing-wax in order
to render the same applicable for money-bags, mail-bags and the like, all sub-
stantially as set forth.
