COMPLETE SPECIFICATION.
Improvements in Apparatus for the Liquefaction and Application
of Adhesive Materials.
I, FREDERIC HUGHES, of 20, Paget Road, West Dulwich, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:
-
My invention relates to improvements in apparatus for the liquefaction and
application of adhesive materials, the object being to provide a portable appliance
for expediting these operations and to prevent the smoking and dirtying of the
material in use. The apparatus may be used for sealing bottles, and other recep-
tacles with wax, for the application of the adhesive material of medical and other
plaisters, for the melting of shellac, gutta-percha, non-conducting material for
electrical purposes, and for the liquefaction of any adhesive material
or materials for any purpose whatsoever to which such an apparatus or
such materials is or may be found applicable. In this specification the apparatus
will be assumed to be applied to the application of wax and the like to the seal-
ing of bottles and other receptacles, but without confining it to that one use.
make reference to the accompanying sheet of drawings in which, Fig. 1, is a side
view, Fig. 2, a plan, and Fig. 3, a front view of the complete apparatus. Fig. 4,
being an isometrical view of a part of the apparatus. Figs. 1 and 1" are respec-
tively isometrical views of the scoop and bolt hereafter referred to.
I
a is a handle of any convenient shape and material, having passed through it
the gas tube b, the end b¹ being for attachment to any flexible or other connec-
tions with the gas supply. The tube b is bent down at c and slopingly upwards
and outwards as at d, an air-hole or air-holes e being provided for converting d
with an atmospheric burner f. Attached to a by the arms g or in any other
manner is the copper scoop having the sides i, the back j, the bottom k, and the
lower front, the bottom of i, j, k, and 1 being on one and the same level. The
bottom k is over the burner f, and resting on k and supported by the sides i and
back is the trough or other shaped copper heater or bolt m, the sides of which (m)
may be attached by screws or otherwise to the sides i. If desired, the bottom k
may be omitted and the bottom of m be immediately over f. Within m is the
removable receiver or *
pourer" n having a bottom o resting easily within m.
The overlipped sides p are to run without difficulty over the sides of h, and the
back to rest against j. Through a slot r in a is free to move up and down the
vertical (and preferably) flat rods to which is attached or with which is formed
a horizontal (or more or less so) arm t the end of which is split as at u so as to
form a clip to carry the stick of wax or other material v. The clip n can be
tightened round by the screw w. The lower end of s is provided with a number
of convenient finger notches .. In use, the wax or like v and the pourer n being
in position, and 6 connected with the gas supply, the burner f is lighted and warms
the heater or bolt m and the pourer n and melts the end of the wax v, which there-
upon runs into n, the appliance being tilted by the user to keep the wax from
running out till required. By placing one of the fingers of the hand holding a

page_text: in one of the notches a, the rod s and wax v can be raised, and by tilting the
apparatus forward, the melted wax in n can be poured where required, and it
will always be free from smoke. The pourer n is made changeable for different
colored wax or materials. In cases where other than wax or like materials is or
are to be used, some modifications of the shape of h and n may be necessary, and
such modification may even be needed in the case of wax or like material accord-
ing to the shape of the material to be melted or to which it is to be applied. With
regard to the heating of the bolt m, it may be effected by other means than a gas
jet. For instance, the pipe passing through the handle may convey compressed
air, and alongside it may be another pipe for conveying hydro-carbon oils spirits
or other inflammable material, a suitable burner being provided below m for con-
suming the material converted into spray by the compressed air. The heating
of m may also be effected by a suitable current or by suitable currents of electricity,
conveyed to m by wires within the handle a, which in this case would be made of
non-conducting material. Any other means may be employed for heating m,
for instance, it might be placed over a separate source of heat, and removed by
the handle for use when the material in n is in a fit condition.
I do not confine myself to the precise shapes, relative proportions or disposition
of parts, as shown in the accompanying drawing or described in the above specifica-
tion, as considerable variation is possible in any of them without departure from
the essential features of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
CLAIMS.
1. Improved apparatus for the liquefaction and application of adhesive materials,
the said apparatus consisting essentially of a handle through which passes a gas
tube terminating in an atmospheric burner, the flame of which plays beneath a
heater or bolt suitably supported in a scoop like arrangement attached to the
handle, the said heater or bolt carrying a removable trough like receiver and
pourer for the melted adhesive material, the said adhesive material in its unmelted
state being carried above the pourer in a clip at the end of an arm projecting
more or less horizontally from the upper end, of a more or less vertical rod sliding
through the above mentioned handle and provided with notches for elevating the
said rod, as and when required, the whole provided for and operating substantially
as described in the above specification, and exemplified in the accompanying
drawing.
2. In apparatus such as are the subject matter of the above Claim 1, the sub-
stitution for the gas heating arrangement of other means of heating the bolt, such
as electricity, or heat from the combustion of hydro-carbon, oils, spirits or other
inflammable materials, alone or in conjunction with compressed air, substantially
as described in the above specification.
3. In apparatus, such as are the subject matter of the above Claim 1, the sub-
stitution for the heating arrangement of any suitable separate source of heat,
substantially as described in the above specification.
