COMPLETE SPECIFICATION.
An Apparatus for Extending Bags of Paper or similar Material.
I, FRANZ LUDEWIG, of No. 19 Feldstrasse, Düsseldorf, in the German Empire,
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 apparatus for extending bags of papers or similar
material, (such as are used by chemists, grocers, etc.) to facilitate the insertion of
goods therein, and is designed to obviate the noxious habit of extending such paper
bags by blowing air into them through the inouth, in order to open them for
insertion of goods. This habit of extending such bags is not only objectionable
on hygienic grounds, but it is tedious, and this invention therefor allows of the
packing and the sale of goods with greater speed than hitherto.
This invention consists of apparatus designed to carry out the before mentioned
object in a simple, speedy and efficient manner.
The apparatus is conveniently constructed of a bellows formed with a peculiar
nozzle to which the bag of paper or other material is connected, so that the latter
can be extended by the operation of the bellows.
In order that my invention may be the better understood, I will now proceed
to describe the same, reference being had to the accompanying drawings, and to
the letters and figures marked thereon.
Like letters refer to like parts in both figures..
Figure 1 shows a sectional view and Figure 2 is a plan of the apparatus.
On a suitably formed base a of wood or other material, is situated a bellows
conveniently constructed of two woods boards 6' 6" between which is attached the
leather body 3 of the bellows b. The lower board or plate 6" has a hole c
through which the air is blown out when the bellows are compressed. A channel d
is formed in the base a through which the air escaping through the hole c passes.
The base a is provided with a nozzle ef connected to the channel d. The nozzle e f
consists of a tube e fixed to the base a and of the mouthpiece fattached to the
tube e.
As shown in the sectional view, Figure 1, the mouthpiece f tapers towards
the end. In the plan Figure 2 it is also shown tapering towards the end, but it
may be formed broad as indicated by the dotted lines shown in Figure 2. The
apparatus is preferably constructed with a nozzle with two interchangeable
mouthpieces which may he attached to the tube e as required.
The bellows is operated by the following simple arrangement. To the back end
of the base a are attached a plate g and a spring plate h both are fixed by screws i
to the base a. The plate 4 is also connected to the upper plate 61 of the bellows,
and it is formed as a spring so that the bellow may be compressed by the depression
of the spring plate h and again automatically extended when the pressure on the
plate / ceases. The plate 9 has two upright lugs k conveniently formed in one
piece therewith. The lugs & have hole m in which pivots a wire handle n, in such
a manner that its depression, acting on the spring plate h and consequently the
plate 6 will compress the bellows.
When it is desired to extend a bag it is placed on the tapering mouthpiece / the
handle n is pressed down, and the air which is thereby driven through the hole c
channel d and nozzle ef, extends the bag.

Having now particularly described and ascertained the nature of this inven
tion and in what manner the same, is to be performed I declare that what I
claim is
1st. An apparatus for the extending bags of paper or similar material used for
the packing of goods consisting of a nozzle on the mouthpiece of which the bag
is placed, and a bellows connected therewith, through the operation of which the
bag is extended.
2nd. A bag extending device as claimed in Claim 1 consisting of a bellows b,
the lower wooden plate 6 of which is screwed to a base a and provided with a
hole c for the passage of air, connected to a channel d in the base a to which the
nozzle ef is attached the upper plate 61 of the bellows being connected with a
spring plate fixed to the base a which again extends the bellows as soon as the
pressure exerted thereon ceases, and a wire handle r arranged so that its operation
allows of the depression of the spring plate h and the consequent operation of the
bellows and whole operation substantially as described.
3rd. In the apparatus claimed in Claims 1 and 2 the arrangement of the divided
nozzle e for the purpose of interchanging the mouth pieces thereon.
Dated this 24th day of June 1896.
