IMPROVEMENTS IN GUMMING APPARATUS
Year: 1883

page_text: LETTERS PATENT to Carl Pieper, Civil Engineer and Patent Agent, resident
at 109-110 Gneisenaustrasse, Berlin S.W. Prussia for an Invention of
"IMPROVEMENTS IN GUMMING APPARATUS" a communication to him from
Johann Eduard Parmentier of Plettenberg, Westphalia, Kingdom of
Prussia
PROVISIONAL SPECIFICATION left by the said Carl Pieper at the Office
of the Commissioners of Patents on the 17th May 1883.
CARL PIEPER, Civil Engineer and Patent Agent, resident at 109-110 Gneisenau-
strasse Berlin, S.W., Prussia, "IMPROVEMENTS IN GUMMING APPARATUSES," [sic]
a communication to me from Johann Eduard Parmentier of Plettenberg,
Westphalia, kingdom of Prussia,
The subject matter of this invention, consists in an apparatus for keeping and
applying liquid gum arabic, glue, &c., in which are obviated the inconveniences
accompanying the ordinary gum flasks and brushes.
The apparatus mainly consists of a receptacle with elastic walls adapted to be
tightly closed, and provided with a beak having one or more small orifices by
which, when a pressure is brought to bear on the walls of the receptacle, the
adhesive liquid contained in the latter, will issue, so that it may then be spread
out by the apparatus itself on the surface to be gummed.
For the purpose of closing the outflow-orifices when the apparatus is not used,
a cap or other suitable part is provided for, adapted to be slipped on the beak,
and fitted with one or more pins or other tapered projections corresponding in
number and shape with the said orifice or orifices. These pins or projections serve
on one hand as stoppers, while on the other, they clear the orifices for the outflow
of the liquid, when they are withdrawn.
The beak of the apparatus may be provided with a small projecting plate of
india-rubber adapted to spread out the gum or glue as it issues.

by the said Carl Pieper in the Great Seal Patent Office on the 6th November
1883,
CARL PIEPER, Civil Engineer and Patent-Agent resident at 109–110 Gneisenau-
Strasse, Berlin S.W Prussia. "IMPROVEMENTS IN GUMMING APPARATUS," a com-
munication to me from Johann Eduard Parmentier of Plettenberg, Westphalia,
Kingdom of Prussia.
The subject matter of this invention consists in au apparatus for keeping and
applying liquid gum arabic, glue, &c., in which are obviated the inconveniences
accompanying the ordinary. gum-flasks and. brushes, such as besmearing of the
bottle-neck and the brush-liandle, adhesion of the stopper, drying up of the liquid
and the brushes.
The apparatus mainly consists of a receptacle having elastic walls and adapted
to be tightly closed, and provided with one or more small orifices by which, when
a pressure is brought to bear on the walls of the receptacle, the adhesive liquid
contained in the latter, will issue, so that it may then be spread out by the apparatus
itself on the surface to be gummed.

On the annexed sheet of drawings the apparatus is represented in three different
modifications.
Fig 1 shows in sectional elevation an apparatus in which the receptacle consists
of an india-rubber tube a, into the lower end of which is inserted the beak b,
made of horn, metal or other suitable material and provided with an outflow
oritice h. At the top the tube a carries a ring c with screw-thread on which is
screwed the cap d Between the ring and the cap a washer of india-rubber is
placed. The outflow orifice h may be closed by a cap e, adapted to be slipped on
the beak b, and lined at its bottom with india-rubber. In this cap is fixed a conical
pin f, which, when the cap is put in its place, penetrates into the outflow orifice h,
and thus on one hand serves as stopper, while on the other hand it has the purpose,
upon being withdrawn, to clear the orifice h for the egress of the liquid, and to
'prevent the apparatus from failing to act on account of an incrustation of the beak.
By means of this apparatus the gum or glue may be applied in narrow stripes, and,
if desired, these may be drawn along a rule.
The apparatus x shown by Fig. 2 in sectional elevation, is adapted for laying on
gum in broad stripes. The beak b, represented perspectively in inverted position
by Fig 3, is in this case made of a certain breadth and is provided with a plate
or spatula of india-rubber g. When the apparatus is used, this plate, or spatula,
spreads out in a stripe of its own breadth the gum or glue issuing from the orifice h.
The said orifice may be made round, or of other suitable form, for instance in the

form of a slit, and there may be one or more such orifices.
closing the same a cap e (see also Fig: 4) adapted to be slipped on the beak binay
be used as in Fig 1, this cap being provided with one or more conical pins
or flat tapered projections f corresponding to the number. and shape of the
orifices h.
The filling orifice may be closed as in Fig 1 by a screw-cap, or by means of the
arrangement shown by Figs 2 and 5, in which an obturating slide k, adapted to be
slipped into the frame or guide 1, presses the india-rubber washer i, on which may
be placed a plate of metal, against the filling orifice.
•
In order to prevent the liquid from accidentally flowing out, after the apparatus
has been put aside, the rib m has been provided for, which serves as a support to
keep the orifices h in an elevated position.

page_text: Or,
The apparatus represented by Fig: 6 has been simplified by the omission of a
special filling orifice, and by forming the part c of Fig 1 as a cap c¹ adapted to be
inserted into the tube a and to be removed when the tube is to be refilled.
this end of the tube is closed altogether, and the beak 6 is arranged to be detached
for the purpose of filling the apparatus. An adhesion of the cap c¹ or the beak b
to the tube a may be prevented by slightly greasing the surfaces in contact with
each other. The part e carrying the pin or stopper f, is shown by Fig:
sisting simply of a strip of sheet metal bent into such a form that it may be slipped
with its end e into the socket n, while the part e' serves as handle. It is in
fact but necessary to provide the said pins or stoppers f, whether there be one or
more of them, with any kind of handle by which they may be withdrawn from
the orifices h.
as con-
Having thus described the nature and object of this invention and the manner
in which it is to be carried out in practice. I hereby claim as new and essential
feature of the same.-
1. A gumming apparatus consisting of a receptacle a with elastic walls, adapted
to be tightly closed, and provided with a beak 6 having one or more outflow-
orifices h, in combination with one or more pins or stoppers fadapted to be inserted
into the orifice or orifices h, and attached to a cap or handle e substantially as and
for the purpose described.
2. The combination with the elastic receptacle a having a perforated beak b, of
the india-rubber spatula g, as herein before specified.
In Witness whereof I the said Carl Pieper have hereunto set my hand and
seal this twenty sixth day of October in the year of our Lord One thousand eight
hundred and eighty-three.
