Improvements in Apparatus for Heating or Melting Wax and like
Substances.
I CHARLES JESSE UNDERWOOD of 236 Wellingboro Road in the Town and
County of Northampton Boot Machine Operator 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 :-
My invention relates more particularly to so called "wax-pots" generally
employed for waxing the thread used in the manufacture of boots and shoes but
it will be seen that the apparatus and modifications thereof may be used for heating
or melting other material than wax.
In the waxpots now in general use there is a danger of the material builing
over, falling down outside the waxpot and becoming ignited by the gas burner or
other source of heat employed and many disastrous fires have thus been caused in
boot and shoe factories.
Now by my invention I provide a waxpot or apparatus for heating or melting
wax, oils or fatty or other like substances by the use of which the danger of fire
is averted.
The waxpot usually used consists of an outer receptacle containing water under
which is the atmospheric gas burner or other source of heat and an inner or upper
vessel of less capacity which contains the wax or material to be melted or heated
and which is supported by a flange or other arrangement over the top of the water
vessel the lower part dipping into and being surrounded by the water after the
manner of a glue pot and if constant attention is not given the water may be
allowed to evaporate when the wax or material will boil over and become ignited
as before mentioned.
In describing my improved means for heating or melting wax and the like I
shall refer to a sheet of drawings accompanying this Specification and to the
figures and letters of reference thereon.
Figure 1. being a transverse vertical section of my apparatus and
Figure 2. a longitudinal vertical section of same.
In carrying out my invention I cast or form an outer casing of metal A having
near its lower extremity a flange B which sits upon a table or shelf C in which is
cut a hole D allowing the parts of the case A and inner case E below the flange B
to pass through same.
I then cast or form another metallic case E of less size in every direction than
the outer case A and so leaving a space of say one inch more or less all round
same and I bolt or secure this inner case E by means of ledges F. F to the back
and front of the outer case A so that it hangs or depends within it.
At a convenient height in this case, say one third from lower extremity I form
or cast a floor or bottom G and the space above this floor contains the water leaving
underneath an open space H inside which is pushed or placed the atmospheric gas
buruer or other source of heat J. The front of the inner casing E and outer
casing A being cut out for the purpose of admitting said burner J. The height of
the inner case E is somewhat less than that of the outer case A but the lower
extremities of each one on same level.
Depending from the outer case A or from the table I fix a receptacle K for cold
water or the like of any convenient size but of sufficient area to cover the bottom
of the apparatus or a tub or receptacle may be placed on the floor below the
apparatus.

page_text: over,
It will be seen that should the material in the inner case by any reason boil
the said material would fall down the space between the inner and outer
cases E and A in the direction shewn by arrows and into the receptacle for
water K. and it would be impossible for it to come in contact with the gas
burner J which lies in isolated chamber H. under the water boiler.
A ledge or
flange L may be formed on each side of inner casing to carry light bars M. M on
which burner J may be placed. The thread N is led into and out of the waxpot
in the usual way. The apparatus altho' shewn of square shape or rectangular may
be made round if desired and adapted to any machine in use.
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 1
claim is
li
1. In so called waxpots used for waxing thread and the like the use of au outer
jacket or case such as A surrounding an inner receptacle containing water in an upper
chamber, such as E, a gas burner or other source of heat in a lower and isolated
chamber such as H and a water receptacle beneath the whole to catch falling wax or
the like the whole apparatus constructed and arranged substantially as hereinbefore
described with reference to the accompanying drawing, or auy mere equivalent
therefor.
2. The apparatus for heating or melting wax or like material constructed and
arranged substantially as hereinbefore described with reference to the accompanying
drawings, or any mere equivalent therefor.
