IMPROVEMENTS IN MALT CRUSHERS
Year: 1855

page_text: COMPLETE SPECIFICATION filed by the said John Lewis and Joseph
Edwards at the Office of the Commissioners of Patents, with their
Petition and Declaration, on the 2nd November 1855, pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
We, JOHN LEWIS, of Dawley Green, in the County of Salop, Blacksmith,
and JOSEPH EDWARDS, of Dawley, in the same County, Stone Mason, do
hereby declare the nature of the 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 Invention consists of improvements in the mechanism employed in
driving or working the rollers of malt crushers, by which we gain an increase
of power and speed, with considerable diminution of labour.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of one of our improved machines; Figure 2, an
end elevation; Figure 3, a section of the same.
We will now proceed to describe its action. (A) is the framework of the
machine, on which the rolls (B, B',) are bushed in proper bearings (C), bolted.
or otherwise secured to the head of the frame (A); (D) is a fly wheel mounted
on the axis of the roll (B); (E,E), are adjusting screws, regulating the distance
,

page_text: between the rolls; (F) is a crank, also bushed in bearings on the head of the
frame (A), and having a toothed driving wheel (G) hung on its axis; (H) is
a pedestal or standard, through the cross head of which comes the screw pin
(I), acting as a fulcrum, in which the bent lever (K) is hung, working freely
on a pin passing through the sides of the screw pin (I) and the lever; one end
of the lever (K) is similarly pinned to the head of a connecting rod (L), the
lower end of which is attached to the head of the crank (F). On the axis of
the roll (B), opposite to that on which the fly wheel is hung, a pinion (M) is
mounted, engaging in: the driving wheel (G) on one side, and on the other in
a smaller toothed wheel (N), on the axis of the roll (B¹). (O) is the hopper
into which the malt to be crushed is to be thrown. By the use of this lever,
therefore, in combination with the fly whicél great power is gained; for on
raising it, as in the act of pumping, motion will be communicated by the
toothed driving wheel (G) to the pinion (M) and smaller wheel (N), whilst by
the assistance of the fly wheel this motion is maintained with a very trifling
amount of power, applied by means of the handle (P) on the extremity of
the lever.
Having thus described the nature of our said Invention, and the manner in
which the same is to be performed, we wish it to be clearly understood that we
do not confine ourselves to these precise details, so long as the principle of
our Invention be retained; but that which we claim is, the application to
malt crushers of the lever, together with the parts in immediate connection
therewith, for the purpose of driving or working the rolls, by which means
increased power with a diminution of labour can be obtained.
In witness whereof, we, the. said John Lewis and Joseph Edwards,
have hereunto set our hands and seals, this Thirty-first day of October,
in the year of our Lord One thousand eight hundred and fifty-five.
JOHN (L.S.) LEWIS.
