Complete Specification Left, 5th Mar., 1892-Accepted, 16th Apr., 1892
PROVISIONAL SPECIFICATION.
Improved Apparatus for Molstening Envelopes, Wrappers, and other
Articles provided with Adhesive Material.
A communication from abroad by FRITZ SYDOW, of Berlin.
I, WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields in the County of London,
Consulting Engineer, and Chartered Patent Agent, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improved apparatus whereby envelopes, wrappers,
stamps, and other articles provided with adhesive material can be moistened in a
rapid and clean manner..
Apparatus for this purpose according to this invention is illustrated in the accom-
panying drawings in which
Fig. 1 is a plan,
Fig. 2 is a front elevation partly in section, and
Fig. 3 is a side elevation.
Mounted on a stand a is a small water vessel in the upper opening of which is
arranged a plug or stem c covered with absorbent material such for example as
flannel, arranged to dip into water in the said vessel. The water is drawn up by
the fabric so that the upper surface thereof remains constantly moist. Upon the
plug bears a metal roller d which is fixed to a movable guide f situated above the
water vessel. With the arrangement described, if the article to be moistened be
drawn through between the roller and the covered plug or stem c with the
adhesive surface downwards, the adhesive substance will be moistened in a uniform
manner by reason of the constant pressure of the roller d.
Instead of the plug or stem c covered with woven or felted fabric, a roller
covered with absorbent material may be employed arranged to rotate in the water
in the vessel b so as to always remain moist. The moistening apparatus is made of
such a width that the moistening action shall be limited to the adhesive surface.
For the purpose of facilitating the introduction of the article to be moistened, for
instance letter envelopes, between the roller and the plug or stem c, guides y are
provided which may be made of thin sheet metal.
Dated this 29th day of February 1892.

A. communication from abroad by FRITZ SYDOW, of Berlin.
I, WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Chartered Patent 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 to improved apparatus whereby envelopes, wrappers,
stamps, and other articles provided with adhesive material can be moistened in
a rapid and clean manner.

page_text: Apparatus for this purpose according to this invention is illustrated in the
drawings left with my Provisional Specification and in which,
Fig. 1 is a plan;
Fig. 2 is a front elevation partly in section; and
Fig. 3 is a side elevation.
Mounted on a stand a is a small water vessel in the upper opening of which is
arranged a plug or stem c covered with absorbent material such for example as
flannel, arranged to dip into water in the said yessel. The water is drawn up by
the fabric so that the upper surface thereof remains constantly moist. Upon the
plug c bears a metal roller d which is fixed to a movable guidef situated above the
water vessel. With the arrangement described, if the article to be moistened be
drawn through between the roller and the covered plug or stem c with the
adhesive surface downwards, the adhesive substance will be moistened in a uniform
manner by reason of the constant pressure of the roller d.
Instead of the plug or stem covered with woven or felted fabric, a roller
covered with absorbent material may be employed arranged to rotate in the
water in the vessel 6 so as to always remain moist. The moistening apparatus is
made of such a width that the moistening action shall be limited to the adhesive
surface.
For the purpose of facilitating the introduction of the article to be moistened, for
instance letter envelopes, between the roller and the plug or stem c, guides g are
provided which may be made of thin sheet metal.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
Apparatus for moistening envelopes and other articles provided with adhesive
material, consisting of a water vessel provided with a plug or stem covered with
absorbent material arranged to dip into the water within the said vessel, or with
a roller covered with absorbent material arranged to dip in the said water, and a
pressure roller arranged in vertical guides above the said plug or stem or roller, the
arrangement being such that when the article to be moistened is drawn between the
moistening plug or stem or roller and the pressure roller, with its adhesive surface
downward, the adhesive surface will be moistened in a uniform manner substan-
tially as described and shown.
Dated this 5th day of March 1892.
