County of York, Fire Clay Manufacturer, do hereby declare the nature of this.
invention to be as follows:-
My invention relates to improved construction of machinery for manufacturing
retorts for gas making purposes and the like. According to my invention I make
the internal die in two or more parts and in connection with the said die 1 employ
an arrangement of worms and wheels. On the axle of the worm or worms I place-
one or more pin wheels around which there passes a chain, strap or perforated belt
the ends of which are connected to the rising and falling table of the retort making
machine the upward and downward movement of which causes the pin wheels.
to revolve whereby one or more studs are gradually moved in such a way as to open.
or close the dies and this operation takes place whilst the table of the machine is.
ascending and descending consequently the internal dies are contracted during the
time the table is descending. and the retort forming, thus the retort is being
gradually tapered during the process of manufacture in its downward movement.
or vice versa. Instead of employing the arrangement of worms and wheels for
opening and closing the die the same result can be obtained by the use of a screw
or cam or other equivalent device.
The description of my improvement as above set forth only relates to the internal
part of the retort but a corresponding form of apparatus may be employed for
forming the outside of the retort.

Improvements in Machinery for Manufacturing Tapered Gas Retorts..
I, JOSEPH MORTON, of the Cinder Hills Fire Clay Works, Halifax, in the
County of York, Fire Clay Manufacturer, 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 to new or improved machinery for the purpose of making
tapered retorts for gas making purposes and the like.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheet of drawings illustrative thereof, wherein Fig. 1 is a cross section taken through
the line A B of Fig. 2, and also a section taken through the line C D of Fig. 2,
whilst Fig. 2 itself is part section of Fig. 1.
The apparatus consists of an outer shell or casing E. This casing E is capable
of expanding or contracting and this function is performed by stuls F mounted

page_text: upon worms or screws G upon the axle of which is secured pin or chain wheels H.
Upon these chain wheels H there passes a chain I connected to the rising aud
falling table of the retort making machine, not shewn in the drawings, cousequently
when the table is ascending or descending the chain, causes the chain wheels H to
revolve whereupon the worms or screws G push inwardly or outwardly the vertical
studs F and this causes the outer shell E to expand or contract whereby the retort
is being gradually tapered during the process of manufacture in its internal part
only, the outer shell or crust of the retort being thicker at one end than the other
end, but it is obvious that the apparatus may be constructed so as to taper the
outer side or shell. In order to prevent the clay from getting into the opening or
recess J in the middle of the divided die, steel plates L are employed to cover up
or overlap the openings. It is quite true that clay will get into the parts marked .J
and will be formed within the retort, but this can easily be scraped off before the
retort is burnt.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the saine is to be performed, I declare that what I
claim is :-
For manufacturing tapered gas retorts, the use and employment of an expanding
and contracting die, constructed substantially as shewn in the drawings and
described herein.
