PROVISIONAL SPECIFICATION.
Improved Pad for Applying or Distributing Liquid Gum.
I, ALBERT WHITFORD HOSKING, of 96 Lancaster Avenue, Fennel Street,
Manchester, in the County of Lancaster, Publisher, do hereby declare the nature
of this invention to be as follows:-
This invention is designed to provide a pad and reservoir by which gum can be
applied to papers documents stamps, patterns or other articles without waste and
in which the gum will be enclosed and kept from contact with air or dust.
The invention consists essentially of an invertible refreshing gum pad comprising
an absorbent pad with a reservoir placed below to contain the gum and from which
it can be caused to flow and distribute its self over the under side of the pad by
inverting or turning it over also appliances for refilling the reservoir and for
indicating when the supply therein is exhausted.
In carrying out the invention I construct a case or receptacle into the top of
which is inserted a pad of suitable absorbent material. This pad I preferably form
with a flanged metal frame or rim which fits the top of the case over which a
cover is stretched of silk and flannellette or other suitable fabric and secured by
shellac or other cement, within the frame I place a number of layers of flannel and
felt or other absorbent material and below these I attach to the flange of the
frame a perforated plate of zinc or other material or wire gauze or the like. The
pad is preferably separate and distinct from the case.
The pad thus formed is inserted into the case resting upon a rim provided on
the top and held in position by suitable composition or cement. Around the pad
which projects through the top I place an ornamental piece of zinc fretwork or
the like covering the flange of the frame on the upper side.
A base or bottom is then fitted in leaving a space or chamber between it and
the perforated plate into which liquid gum can be supplied through an opening
formed in the front, end, side, bottom, or other convenient place for the purpose.
Above the bottom plate is placed an inclined plate or shelf which will cause the
gum to flow to one end of the reservoir, and in the bottom plate I construct at one
end a well or its equivalent to receive the gum all of which is caused to gravitate
thereinto.
The aperture through which the gum is admitted is provided with a ball or
other suitable valve to prevent the return flow of the gum and is preferably closed
on the outside by a screw or other stopper.
Outside the bottom of the case I attach an appliance for indicating whether the
reservoir is full or requires filling, this comprises a bar or lever placed crosswise
which can be rotated from the left to the right and vice versa and which when in
one position presents two or more pivots points or edges on which the appliance
is thereby pivoted. If the reservoir be full it gravitates or overbalances to the
end at which the well is placed, if empty or nearly so to the opposite end.
The apparatus may be made of rectangular, oval, circular, or other suitable or
convenient form, and is covered by a lid.
The surface of the pad when exhausted may be replenished by inverting the
appliance, allowing the gum to flow through the perforated plate.

Improved Pad for Applying or Distributing Liquid Gum.
I, ALBERT WHITFORD HOSKING, of 96 Lancaster Avenue, Fennel Street,
Manchester, in the County of Lancaster, Publisher, 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 is designed to provide a pad and reservoir by which gum can be
evenly distributed and applied to papers, documents, stamps, cuttings from journals,
photographic mounts, patterns or other articles without mess or waste and in
which the gum will be enclosed and kept from contact with air or dust.
The invention consists essentially of an invertible refreshing gum pad comprising
an absorbent pad with a gum reservoir beneath from which the gum is made to
flow and distribute itself over the under side of the pad by inverting or turning it
over whenever its depleted condition at work shall so require.
My improved gum pad will be fully described with reference to the accompanying
drawings.
Fig. 1. External perspective view.
Fig. 2. Longitudinal section.
Fig. 3. Transverse section.
I construct a case or receptacle A of tin sheet or other suitable material into
the top of which I insert a pad B of any suitable absorbent material. The pad B
is formed of a flanged metal frame or ring C which fits into the top of the case A
over which a cover D of silk satin or other suitable fabric is stretched and secured
by pitch shellac or other cement. Above the joint so formed I place an ornamental
strip or border E of brass fretwork or the like which more securely holds the
cover D in place. Within the recess of the frame C I place a number of layers
of flannel and felt or other absorbent material F and below these I place a
perforated plate G of zinc or other material or wire gauze or the like. The
perforated plate G is held up against the under side of the absorbent material F
of the pad which it holds in position with necessary degree of solidity and presents
a firm base and support for the structure of the pad itself.
The frame C is when covered with the covering material D inserted in the 3
case A resting against the top flange a and is held in position by solder or other
suitable means and the perforated plate G rests upon and is held in position by a
number of pins K which are soldered to a longitudinal tube H.
The gum by which the pad is saturated renders it non-porous and consequently
any increase of atmospheric pressure caused by increase of outside temperature or
otherwise would project the gum contained in the absorbent material through the
cover D and result in flooding the upper surface of the pad. An increase of
internal pressure may be occasioned by the direct action of beat rays or by the
percussioning of the air within the reservoir by rapid movement of the gum in
handling the apparatus. To obviate this I construct an arrangement of ventilating
tubes the operation of which secures freedom from pressure of air within the
reservoir no matter what changes of temperature may arise. This ventilator
comprises the longitudinal perforated tube H with an outlet vent tube h carried
through the side of the case A and terminating at the other end in the centre of
the perforated tube H. The position of these two tubes is such that the pad can 4
be inverted or placed in any position whatever without causing contact of the gum
with the outlet vent tube h.
At each end of the central tube H I form a chamber M by means of the
division plates m. These chambers are filled with flock, sponge or other loose
absorbent material through which (not being placed under any pressure whatever) 5

page_text: the gum readily penetrates. This material in constant state of abundant saturation
is always in contact with the corners and ends of the fabrics forming the pad
which are thereby kept in necessary plastic and moist condition which owing to
the metallic rigidity of the frame at the corners and ends would otherwise be dry
and hard and altogether impervious after a short time at work.
A base or bottom N is fitted in leaving a space or chamber between it and the
perforated plate into which liquid gum can be supplied through an opening O
formed in the front or other convenient place for the purpose. The opening O is
closed by a plug or stopper P screwed therein.
Below the bottom plate N may be fixed a block of wood R to form a stand. In
this I provide a hole or slot r to fit over a fixed or movable pin or stud to prevent
sliding movement on surface of table or desk when at work.
The apparatus may be made of rectangular, oval circular, or other suitable or
convenient form, and is covered by a lid.
The surface of the pad when depleted may be renewed by inverting the appliance,
allowing the gum to flow through the perforated plate and thence to the surface of
the pad.
My improved pad may also be filled with water or ink and be used as a damping
or inking pad.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. An improved pad for distributing liquids constructed and arranged substantially
as described and shown.
2. An improved appliance for supplying or distributing liquids constructed with
a chamber to contain the liquid a pad of absorbent material and a perforated plate
to support the absorbent material and to allow the liquid to flow through thereto.
when inverted substantially as described.
3. In an appliance for supplying and distributing liquids provided with a
reservoir below the pad to hold the liquid the combination with the absorbent.
material forming the pad of a perforated plate by which it is supported in position
such perforated plate being shorter than the pad so as not to apply any pressure
to the ends of the absorbent material substantially as and for the purpose described
and shown.
4. An appliance for supplying and distributing liquids constructed with a
casing A embracing a reservoir to hold the liquid in combination with a pad formed
of layers of absorbent material resting upon a rigid perforated plate above the
reservoir which is divided into three compartments the end chambers of which are
filled with loose absorbent material through all of which the liquid can flow to the-
surface when the pad is inverted, substantially as described.
