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
statement
My invention relates to improvements in apparatus for the liquefaction and
application of adhesive materials and has reference to an improvement in the
method of lifting the adhesive material as shewn in Letters Patent 29938 granted
to me under the date of 17th December 1897. In the apparatus shown and
described in the specification of the said Letters Patent the adhesive material is
raised by a notched lever projecting below the handle of the appliance and this
projecting part prevented the appliance from being set down except on its side
which is inconvenient. A further disadvantage was the liability of the receiver
or pourer to slip out during use. To remedy these defects I proceed in or in
about the manner shown in the accompanying drawing which is a side view.
I
hold the wax or other adhesive A in a spring clip B at one end of the arms C.
The arms C are attached to the block D free to run up and down the pillars E
upstanding from the base F attached to the top of the handle a, the fore and aft
edges of the block D being grooved to embrace a portion of the pillars E, and to
further facilitate its movements grooved pullies are provided to work on the axles G.
The block D is lowered by pressure on the finger piece H connected with its under
side and is raised by the action of a spiral spring contained in a tubular pillar J
acting on a piston at one end of the rod K the upper end of which is attached to
the under side of the block D. The pourer or receiver is prevented from slip-
ping out by a headed pin L provided at its back q the shank of the pin L entering
an open ended slot in the back of the scoop h containing the heater or bolt m.
In order that the apparatus may be stood up when out of use provide a hollow
or other foot M. The other parts of the apparatus remain as described in the
above mentioned earlier patent and the same lettering has been retained, 6 being
the gas tube and f the burner.
I do not confine myself to the precise shapes and proportions shown in the
drawings as some variation is possible without departure from the spirit of the
invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. In apparatus for the liquefaction and application of adhesive materials such
as form the subject matter of British Letters Patent 29938 A.D., 1897, the
improved means for raising and lowering the adhesive, the said means consisting
essentially of a clip to grasp the adhesive, arms to carry the said clip and a block
to carry the said arms, the said block being free to ride up and down pillars up-

page_text: standing from the handle of the appliance and kept in an upward position by a
plunger or rod and piston working in a tubular upright having within it and
below the piston or plunger a spiral spring, the said block having a finger piece
by which it can be lowered as and when required, the whole substantially as
described in the above specification and exemplified in the accompanying drawing.
2. In apparatus for the liquefaction and application of adhesive materials such
as form the subject matter of British Letters Patent 29938 A.D. 1897, the means
for keeping in position the receiver or pourer by a headed pin projecting behind
the said pourer having a shank to enter an open ended slot provided at the back
of the scoop in which the pourer rests, substantially as described in the above
specification and exemplified in the accompanying drawing.
3. In apparatus for the liquefaction and application of adhesive materials such
as form the subject matter of British Letters Patent 29938 A.D. 1897, the com-
bination therewith of a foot on which the apparatus can stand when out of use,
substantially as described in the above specification and exemplified in the accom-
panying drawing.
4. In apparatus for the liquefaction and application of adhesive materials such
as form the subject matter of British Letters Patent 29938 A.D. 1897 the com-
bination of parts substantially as described in the above specification and exempli-
fied in the accompanying drawings and together forming and operating as improved
means for raising and lowering the adhesive, preventing the pourer from falling
out and providing a foot on which the apparatus can stand.
