IMPROVEMENTS IN MALT CRUSHERS
Year: 1855

page_text: LETTERS PATENT to Joseph Partridge, of West Bromwich, in the County
of Stafford, Plumber, and John Kirkham, of the same Place, Engineer,
for the Invention of "IMPROVEMENTS IN MALT CRUSHERS"
COMPLETE SPECIFICATION filed by the said Joseph Partridge and John
Kirkham at the Office of the Commissioners of Patents, with their
Petition and Declaration, on the 12th September 1855, pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
We, JOSEPH PARTRIDGE, of West Bromwich, in the County of Stafford,
Plumber, and JOHN KIRKHAM, of the same Place, Engineer, 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 in adding to malt-crushing rollers certain apparatus
that will ensure a constant and regular supply of malt from the hopper to the
rollers, by which any clogging of the rollers arising from too great an accumu-
lation of malt upon them will be prevented.
DESCRIPTION OF THE DRAWINGS.

page_text: We will now proceed to describe the construction and working of the parts
of our Invention. (A) is a shaft or spindle, on which is keyed a crank handle
(B). when the machine is to be worked by manual power; or if worked by
steam power, a driving pulley is mounted thereon; the spur wheel (C) is also
hung upon this shaft, and drives the toothed wheel (D) mounted on a second
shaft (E); these two shafts or spindles are the axes of the crushing rollers
(F. F) and on the opposite end of the shaft marked (E), another toothed
wheel (G) is fixed, gearing into a smaller one (H) upon the spindle of the
brush (1); this brush may have metallic, bristle, or any other suitable points,
and by the communication already described, is set in rapid motion through
the series of toothed wheels on turning the crank handle (B), or otherwise
applying power to the spur wheel (C). (K) is the hopper, into which the malt
is thrown, a plate (L) being provided, as shewn in Drawings, to prevent its
falling upon the brush and to guide it to the proper point. A second plate
(M) is hinged or pivotted, as seen at (N), and provided with an adjusting
screw (0) at the back to regulate its contiguity to the brush; (P) is a door in
the framework, to admit of the examination of the crushing rollers in case of
accident or stoppage. The malt on being thrown into the hopper is received
into the trough formed by the two plates (L and M), and by the rapid revo-
lution of the brush (1), it is allowed to drop past gradually; the proper flow
of the malt upon the rollers is regulated, and clogging or accumulation of the
malt is avoided.
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, so long as the material points of
our Invention be retained; but that which we claim is, the application to malt
crushers of the plates (L and M), and the revolving brush (I), with its gearing,
or any mere modification of the same apparatus, for regulating the flow of malt
to the crushing rollers, as herein more fully set forth and specified.
In witness whereof, we, the said Joseph Partridge and John Kirkham,
have hereunto set our hands and seals, this Sixth day of September, in
the year of our Lord One thousand eight hundred and fifty-five.
