and for Cleansing Stuffing Materials.
We, MORITZ-EHRLICH, and LEONOR BENDIX, Merchants, of Hanover, in the German
Empire, 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 :-
Our invention relates to apparatus for stuffing beds, quilts and such like articles
and consists in an improved arrangement or construction of apparatus for said
purpose, so that the down, flocks, cotton, hair, sawdust, or other material for stuffing
heaped up in a feed room or box are sucked in by an exhaust ventilator and loosened
by the fan of the same, while they are at the same time conducted to the article to
be stuffed by the delivery or blast pipe of the ventilator.
The apparatus of this kind hitherto used force the stuffing material into the articles
by a current of air compressed by a fan which passes through an air tight closed
receptacle filled with the material. The air frequently balls the material, for instance
eider down, together, so that the apparatus gets clogged or the material is driven in
unequal quantities into the mills or covers, for when the current of air has cut a
passage through the material in the receptacle, it only carries small quantities of down
into the quilt or cover. The air thus for the most part passes through the receptacle
without carrying stuffing material with it and escapes through the cover or tick
without performing work. If the receptacle is made so small that the current of air
impinges upon all the material and carries it forward, the receptacle is quickly emptied
and must frequently be filled. The object of our invention is to obviate these
drawbacks.
Our apparatus is shewn on the drawing appended hereunto in a perspective view.
The material, for instance eider down, is filled into the feed box A through the
lid a. A spy window bis shewn in the side of the feed box, instead of which latter
an entire feed room may be used. The suction pipe c of an exhaust fan B, driven in
any suitable way, enters the box. The delivery or blast pipe d of the exhaust fan B
fitted with the conical tube C contracted to the size of the elastic filling hose pipe D

page_text: the section of which is so proportioned that the material drawn in by the suction
pipe c passes out in the required density for stuffing the bed cover or quilt. While
the exhaust fan works, air is drawn in from the outside through the grid e and while
flowing to the suction pipe c carries the material with it. The pipe c is enlarged near
to the exhaust fan, so that the material is separated or opened out by the expanding
air. The material thence passes between the blades of the exhaust fan and is completely
loosened or opened by the circling air currents and carried by the outflowing air
through pipes d, and D into the quilt or other article.
In order to prevent material balled together by dampness and thrown into the
feed box A from being drawn into the exhaust fan in this condition, an agitator or
beater E is arranged in the box A, which when rotated by hand or power beats up
and separates the stuffing material. As the air is drawn into the box A or an
equivalent room by suction, it is possible to use an efficient current of air of any
desired dimensions or section and uniform slow speed, so that the material is not
balled together in the feed box or room. The speed or force of current becomes
greater only in the suction pipe, which however cannot injuriously affect the material,
as it enters the pipe in a loosened or opened state, and is subjected to a further
opening process in the exhaust fan itselfiand finally becomes condensed in the pipe C
to the extent required for an uniform stuffing of the quilt or other article.
The loosening or opening action of the beater and exhaust fan also serves to free
the material from dust and impurities, so that where down or feathers are used for
stuffing, these are filled into the covers in a cleansed state. The apparatus thus
serves not only as a stuffing apparatus, but may also be used as a cleansing or
purifying apparatus for stuffing materials, which may be passed through it, without
being stuffed into covers.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is,
Firstly, the general arrangement of stuffing apparatus substantially as herein
described and illustrated by the drawing.
Secondly, in stuffing apparatus the combination of an exhaust fan and a beater or
agitator placed near to the suction pipe of said exhaust fan, substantially as herein
described and illustrated.
Thirdly, the use of the stuffing apparatus herein described for purifying or cleansing
stuffing materials.
