IMPROVEMENTS IN MALT CRUSHERS
Year: 1855

page_text: COMPLETE SPECIFICATION filed by the said Ephraim Green and Jacob
Green at the Office of the Commissioners of Patents, with their Petition
and Declaration, on the 10th November 1855, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
We, EPHRAIM GREEN and JACOB GREEN, of West Bromwich, in the County
of Stafford, Ironfounders, do hereby declare the nature of our said Invention
for "IMPROVEMENTS IN MALT CRUSHERS," and the manner in which the same is
to be performed, to be particularly described and ascertained in and by the
following statement, (reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereon,) that is to say:-
Our improvements consist in enclosing the working parts of malt crushers,
so that whilst the machine is in operation, the malt dust which would other-
wise fly off and be lost, is by our Invention retained; much waste is conse-
quently prevented and valuable matter secured.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of one of our improved machines; Figure 2,
an end elevation; and Figure 3, a section of the same.
We will now proceed to describe the machine and its working. (A) is the
frame, supporting the pedestal (B), in which the rolls (C, C¹,) are mounted;
on the axis of the roll (C) is hung the fly wheel (D) on one side, and on the
other the winch handle (E), by which the machine is worked, on the shaft of

page_text: which is placed the pinion (F), and by its engaging in the toothed wheel (G)
on the axis of the roll (C) the latter is driven; (II) is a box or drum in
which the rolls work, being provided with a closed spout (I), through which
the malt is to be run off; (K, K,) are two cheek plates, fixed in the interior
of the drum (H), and touching or nearly touching the peripheries of the rolls,
and are for the double purpose of preventing the malt from falling on the
wrong side of the rolls, and also to keep the rolls clear by acting as scrapers.
In the chamber (L) under the hopper (M) is provided a sliding damper (N),
which can be drawn out to any desired point, thus regulating the supply to the
rolls; this damper is kept in position by the screw pin (0) pressing against its
under side. In the process of crushing or grinding the malt, a considerable
quantity of fine dust, being an essential part of the malt, is thrown off, and in
the ordinary manner of crushing is lost. By our improvements we are enabled
to retain this dust in the drum or casing (II), whence it is withdrawn with the
rest of the malt into a sack gathered round the neck of the closed spout (I);
we thus avoid much waste of the most valuable part of the malt.
Having thus described the nature of our said Invention, and in what
manner the same is to be performed, we wish it to be clearly understood that
we do not confine ourselves to these precise details; but that which we claim
is, the improvements described in casing or enclosing the working parts of
malt crushers in such manner as to retain all the malt dust created by the
crushing process, by which improvements we avoid wasting an essential part
of the malt, as herein more fully set forth and specified.
In witness whereof, we, the said Ephraim Green and Jacob Green, have
hereunto set our hands and seals, this Thirty-first day of October, in
of our Lord One thousand eight hundred and fifty-five.
