PROVISIONAL SPECIFICATION.
Improvements in Heater Boxes and Gas Burners for Blocking
Presses and other like Purposes.
JOSHUA ALBAN TILLCOCK Engineer 131 Goswell Road in the City of London do
hereby declare the nature of this invention to be as follows:-
My invention has for its object to provide heater boxes for blocking presses
and other purposes of an improved shape; to construct the heating chamber of
such heater boxes in such a manner as to secure a maximum amount of heat with a
minimum expenditure of gas, and to provide a gas burner suitable for heating such
heater boxes or other surfaces of a flat or similar nature.
The heater box described herewith can be made to suit all kinds of blocking
presses, and its shape may be of any convenient form as circumstances require, but is
usually rectangular on the sides and bottom, and is provided with a circular boss to
take the pressure from the piston to which it is fixed by any suitable moans.
The heating chambers are two in number (more or less can be used), and are
somewhat oval in shape, of equal size at each end and rising at the top towards the
middle and falling again to the back end or opening, the bottom of chamber follows
the shape of the openings throughout-thus a larger chamber is formed than is
apparent from the ends.
The burner is made of gas tube or any other material and is provided with holes of a
suitable size and number, this tubo is flattened out after the holes are made which
causes them to assume an oblong shape, these holes are then broached out with a tool
in such a manner that the gas is made to flow through them on to the bottom of the
heating chamber where it is burnt.
The burner is fed through an air hell of convenient size and shape and is fixed by
suitable means to the heater box.

Improvements in Heater Boxes and Gas Burners for Blocking
Presses and other like Purposes.
I JOSHUA ALBAN TILLCOCK Engineer 131 Goswell Road London E.C. 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 has for its object to provide heater boxes for blocking presses and
other purposes of an improved shape, to construct the heating chambers of the
same in such a manner as to secure a maximum amount of heat with a minimum
expenditure of gas and to that end to provide a gas burner suitable for heating such
heater boxes or other surfaces of a flat or similar nature.
The heater box described herein can be made to suit all kinds and sizes of blocking
presses and in shape may be of any convenient form as circumstances may require
but is usually rectangular on the sides and bottom and it is provided with a circular
boss to take the pressure from the piston of the press to which it is fixed by any
suitable means.
The heating chambers are usually two in number (more or less can be used) and
are somewhat oval in shape, as shown in the end view Fig. 2, of equal size at each
end and rising at the top towards the middle and falling again to the back end or
opening, as shown in the longitudinal section Fig. 1, the hottom of chamber follows
ID 31

page_text: the shape of the openings throughout and thus a larger chamber is formed than is
apparent from the ends.
The burner is supplied with atmospheric gas through an air bell or Bunsen burner
and has as many arms or branches as there are chambers to be heated and is made of
gas piping or any other material, specially flattened, and provided with holes of the
desired size and number so broached out as to cause them to throw out a flame directly
onto the bottom of the chamber where only the heat is desired to be applied. This
Durner is shown in section in Fig. 3.
Having now particularly described & 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 ;
1. The internal enlargement of the heating chamber.
2. The flattened or oval shape of the burner with holes therein substantially as
described.
