PROVISIONAL SPECIFICATION.
Improvements in Machinery or Plant for the Manufacture of Patent
Fuel.
JAMES PRING, 11 Trinity Place, Newport Mon., Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to and consists cheifly of the combination of a pusher plate,
having a reciprocating motion, and being placed underneath, or used in conjunction
with a pug mill of any ordinary construction, the said plate having cast in, fixed
upon or carrying the mould or moulds, in which the patent fuel blocks, are formed
and pressed, together with pressing cylinder, connected to a lever, by means of which
lever, the brick or block, is pressed when in mould, and when pressed discharged
therefrom.
Dated this 12th day of February 1889.
COMPLETE SPECIFICATION.
Improvements in Machinery or Plant for the Manufacture of Patent
Fuel.
I, JAMES PRING, 11 Trinity Place Newport, Mon., Engineer, 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 and consists cheifly of the combination of a pusher plate,
having a reciprocating motion, and being placed underneath, or used in conjunction
with a pug mill of any ordinary construction, the said plate having cast in it, the
mould or moulds in which the patent fuel blocks are formed and pressed, together
with a pressing cylinder connected to a lever by means of which lever, the brick or
block is pressed into the required shape and size when in the mould and when pressed
the pusher plate is withdrawn to the other end of stroke as shown by Fig. 2 on
plan & discharged therefrom, and in order to clearly elucidate the manner and
character of my said invention, I now refer to the accompanying drawing whereon
Fig. 1 is a plan of the machine, Fig. 2, sectional elevation and Fig. 3 an end view.
This drawing shows one arrangement or modification of several it may be convenient
for me to adopt. Letter A is a pug mill of any discription and which may be
vertical as shown, horizontal or inclined, and attached direct or indirectly to the
machine frame B. in such a manner, that the prepared material for the manufacture
of patent Fuel Briquettes, is delivered into the mould C. in the reciprocating pusher
plate through opening J in bottom of framing. When the proper quantity of
material has been delivered into the said mould or pusher plate C, in which the
patent fuel blocks or block is formed then the pusher plate travels back to the
centre of framing K, at which is fitted a wrought iron bar for compressing the fuel
against steam, hydraulic, or other pressure is admitted into the cylinder D. thus
raising one end of the lever E. the other end of the lever E moves upon a fulcrum F
whilst the pin G is connected with lever E forces the stamper L through the
mould C. whereby the material delivered into the mould or pusher plate is compressed
to the proper degree of hardness. The briquette or block being now formed the
lever E falls down to a horizontal position and the reciprocating pusher plate is
moved to the position shown on the drawing, where the block or briquette M, has
just been discharged from the mould, by means of the cylinder D and the lever E
acting through the pin H and thus forcing the block or briquette from the mould.

page_text: The reciprocating pusher plate may be worked by any suitable mechanical con-
trivance adapted to varying circumstances, and the lever E may be worked by any
suitable mechanism, and be placed in any desired position.
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,
1st. The combination of a reciprocating pusher plate, contained wherein or attached
thereto is a mould or recess, and a lever worked by any applicable mechanism, which
lever is attached to or connected with, directly or indirectly a die working into the
said mould for the purpose of compressing the material delivered into such mould
into blocks or briquettes of patent fuel.
2nd. The combination of a reciprocating die or plate together with a lever for
compressing the material into the said die or mould, as before described, and the
utilization of the same lever for the subsequent discharge from the mould of the
pressed block or briquette of patent fuel, after such block or briquette has been formed
and compressed.
