PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Compressing
Substances into Convenient Forms.
I, THOMAS MESSENGER of 2 Clarence Lawn, Dover, in the County of Kent,
Engineer do hereby declare the nature of this invention to bo as follows:-
This invention relates to machinery or apparatus for heating and regulating or
measuring the substance to be supplied to the filling plunger of compressing machines
and more particularly to the machine for which I have obtained protection under the
No. 2293 of 1888.
In the hopper or receiver of the compressing machine I place a vertical revolving
shaft having radiating knives similar to those used in a pug mill, the bottom knives
scraping over the bottom of the hopper or receiver as they revolve, and when the
filling plunger has receded in its groove, which is formed in the bottom of the
receiver, these knives fill in the substance supplied thereto through the open top of
the groove. I now prefer that this filling groove should have its sides vertical and its
bottom horizontal, and 1 place the groove at a sufficient distance from the centre of
the hopper or receiver to clear the footstep of the revolving shaft.
For the purpose of regulating or measuring the proper quantity of the substance
to be filled into the groove I adjust the admission of the substance by two slides
which I place over the top of the groove, one slide in line with the groove and the
other at right angles; the one at right angles giving the first admission or opening to
start the machine and the other the final adjustment of opening for the exact quantity
to produce a pellet of the desired consistency; or I may effect my object by means
of a single slido suitably arranged.
I make provision for the admission of steam into the bottom of the hopper or
receiver for heating purposes, as required in the case of compressing small coal into
"Briquettes."

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Compressing
Substances into Convenient Forms.
I THOMAS MESSENGER, of 2 Clarence Lawn, Dover, in the County of Kent,
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:
This Invention relates to machinery or apparatus for heating and regulating or
measuring the substance to be supplied to the filling plunger of compressing machines
(and more particularly to the machine for which I have obtained protection under the
No. 2293 of 1888) which I will now proceed to describe with reference to the accoun-
panying Sheet of Drawings upon which
Figure 1 is a sectional elevation of the Receiver of a compressing machine as it is
mounted on the nlungan brooket R

page_text: or channel A formed in the plunger brackot Bin which the filling plunger F recipro-
cates. Hand H₁ are two slides which regulate the admission of the substance into
the channel A to be filled into the hole in the die G preparatory to its being compressed.
I is a revolving shaft having a scraper blade J at its lower end, and above other
blades or stirrers K, K, similar to an ordinary pug mill, and I prefer, in order to
provide the lower end of the revolving shaft I with a footstep bearing L, to place the
channel A sufficiently out of the centre of the receiver to admit of this footstep bearing.
M, M, are pipes by means of which jets of steam may be conveyed into the bottom
of receiver for the purpose of heating any substance which may require to be heated
previous to being compressed.
The modus operandi is as follows:-
The substance to be compressed is fed into the hopper or receiver Q; the revolving
shaft I with its scraper blade J and stirrer blades K, K, having sufficiently mixed the
substance at the same time that it has become properly heated by the steam jets conveyed
through the pipes M, M, the slide H is opened out fully (as shewn by. the.dotted
lines in the drawing) giving the first admission on starting the machine; so that
as the plunger F recedes the revolving scraper J fills the substance into the
channel A. The slide H¹ is then opened sufficiently to produce the final regulation
or measurement of the substance into the channel A. Then, on the return stroke.of
the filling plunger F, the exact quantity is filled into the die G. so that when com-
pressed a pellet of the desired consistency may be produced.
The slides H and I may be opened by hand, or otherwise, and in some cases the
regulation or measurement may be effected by one slide only. The exact quantity of
any substance passing into the machine to be compressed is regulated entirely by
the size of the opening produced by the slide or slides; when using the two
slides H and H this necessary opening is produced by the sum of the openings of
the two slides; but the slide H' may by itself produce this necessary opening.
The shaft I may be revolved by any suitable gear either from the compressing
machine, or otherwise, and the stirrers and scrapers be of any convenient form.
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 :-
1. In machinery or apparatus for compressing substances into convenient forms a
hopper or receiver having a rotating shaft carrying stirrers and scrapers in communi-
cation by slides with a channel in which travels a reciprocating plunger in combination
with a compression die or mould and provided with steam inlets the whole combined
and arranged so that the substance filled into the receiver may be simultaneously heated
and mixed therein and introduced therefrom in regulated quantity into the channel to
be passed thence into the compression die by the movement of the reciprocating
plunger substantially as hereinbefore described with reference to the accompanying
drawings.
2. The slides H and Hor H₁ alone in combination with the channel A and filling
plunger F for regulating or measuring the quantity of substance to be entered into
the die or mould at each stroke of the plunger substantially as described:
3. The combination of apparatus whereby the mixing measuring and heating of the
substance to be compressed or the mixing and measuring only. are, simultaneously
performed substantially as described with reference to the accompanying drawings.
