PROVISIONAL SPECIFICATION.
Improved Means for Grinding and Crushing Malt, Grain Generally,
Beans and other Legumes, Seeds and the like.
I, GEORGE DANIEL HUBBACK, of 25 Guild Street, Burton-on-Trent,
Millwright, do hereby declare the nature of this invention to be as follows:-
:-
Hitherto for the purpose of grinding or crushing malt, grain seeds, legumes and
the like, a pair of grinding or crushing rolls or rollers were used, both of which
had to be accurately faced.
Now in accordance with my invention, I dispense with one of the two rollers, and
I provide the outer periphery of the other roller with longitudinal grooves or
serrations; while I substitute for the second roller, an inclined plate, which is
likewise grooved or serrated on the plane facing the roller. Any well known means
of adjustment may be adopted for regulating the interstitial space between the
roller and the inclined plate, according to the nature of the substance or substances
under treatment. In cases where it may be desired to duplicate the rollers, both
faces of the inclined plate would be grooved or serrated.
I also employ a hopper into which the malt grain, seed or other material is
placed, in order to be fed by a stirring roller into a shoot, whence it passes between
the roller and the plate, between which it is ground, and crushed, falling
subsequently into suitable bags or other receptacles. Said roller which is provided
with longitudinal grooves or serrations is mounted upon a main shaft carrying a
fast and loose pulley; a third pulley is employed to impart by means of a belt,
rotation to the feeding and stirring roller. The main shaft and with it the roller is
capable of lateral adjustment, its bearing being fixed in any desired position, by
means of screws moving through perforated upright extensions of a support, carried
by the framework and furnished with plates at each end. Said inclined plate
moving between suitable guides is fixed in any desired manner to the support and
frame of the machine, this plate being provided with tapped lugs or projections
through which pass screws actuated by a handle, and the other end of which is
fixed. By turning said hand wheel in one or in the other direction the plate can
be raised or lowered, and thus adjusted in any suitable position up or down. The
surface of this plate which is in front of the roller is likewise provided with
transverse serrations which grind in conjunction with those of the roller, the seeds
or grains passing between the two.

H is the hopper in which the grain seed or other material is placed in order to
be fed by the stirring roller a into the shoot whence it passes between the roller r
and the plate e between which it is ground and crushed falling subsequently into
suitable bags or other receptacles. The roller which is provided as shown in the
drawings with longitudinal grooves or serrations is mounted on the main shaft S
carrying a fast and loose pulley pland p respectively, and a third pulley p³ imparting
by means of a belt, a rotation to the pulley p³ mounted on the shaft s of the feeding
and stirring roller a. The main shaft S and with it the roller is capable of lateral
adjustment, its bearing being fixed in any desired position by means of the screws f
moving through perforated upright extensions of the support m carried by the
framework F and furnished with the plates flat each end. c is an inclined plane
moving between suitable guides fixed in any desired manner to the support m and
frame F, this plate being provided with tapped lugs or projections & through which
pass the screws e actuated by the handle e¹ and the other end of which is fixed.
By turning the hand wheel e' in one or in the other direction the plate can be
raised or lowered and thus adjusted in any suitable position up or down. The
surface of the plate c which is in front of the roller is likewise provided with
transverse serrations which grind in conjunction with those of the roller r the seeds
or grains passing between the two.
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 :-
:-
First. The improvements in mills for grinding or crushing malt, grain, seeds
and like substances, arranged, constructed and operating substantially as herein
described and shown.
Second. In mills for grinding and crushing malt, grain, seeds and like substances
the combination of longitudinally fluted or serrated and laterally adjustable roller
with a transversely fluted or serrated and longitudinally adjustable inclined plate
substantially as herein described and shown.
