IMPROVEMENTS IN ROLLER- MILLS
Year: 1884

page_text: I EMIL LUDWIG HERMANN BAUERMEISTER of Hamburg Germany Mill-Wright
do hereby declare the nature of my invention for "IMPROVEMENTS IN ROLLER-
MILLS" to be as follows:-
The objects of my improvements in roller-mills are mechanisms for automatically
disengaging and for dislocating or adjusting the rollers while in motion.
The hopper of the roller mill is provided with a flap which is held open by the
grain, until the latter is nearly expended, when the flap rises by means of a
counterweight. This motion causes a finger, attached to the hinge bolt of the flap,
to turn a lever, thus disengaging a pawl at the end of the said angle-lever from
a tooth of a swinging knocker. The latter, after becoming free, swings downwards
and knocks at an arm of a ratchet-lever, which disengages a stop retaining the
movable bearings of the one roller which is pushed by springs against the other
roller, but secured by a set-screw from touching the roller turning in a stationary
bearing such springs acting against the said stop dislocate the movable roller
automatically. The stop may also be raised or lowered by a hand lever, whereon
the ratchet lever is pivoted; thereby the distance between the rollers can easily
be adjusted during the rotation of the same.

page_text: I, EMIL LUDWIG HERMANN BAUERMEISTER, of Hamburg, Germany, Millwright,
do bereby declare the nature of my invention for "IMPROVEMENTS IN ROLLER-
MILLS," and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The objects of my improvements in roller-mills are mechanisms for automatically
disengaging and for dislocating or adjusting the rollers while in motion.
I attain these objects by the mechanisms as illustrated in the accompanying
drawing, in which-
Figure 1 is a side elevation, partly in section, of a roller-mill provided with my
said improvements; Figure 2 is a plan, and Figure 3 a front view thereof.
Similar letters refer to similar parts throughout the several views.
According to my invention, the hopper, a, of the roller-mill is provided with
a flap, b, which is held open by the grain until the latter is nearly expended, when
the flap rises by means of a counter weight, d, attached to the lever, c, which is
mounted on the shaft, e, whereto the flap is pivotted. This motion causes the
finger, f, attached also to the shaft, e, to turn the angle lever, g h, thus disengaging
the pawl, i, at the end of the lever-arm, h, from a tooth of the swinging knocker, k.
The latter, after becoming free, swings downwards, and knocks at the arm, l, thereby
disengaging the ratchet, m, from the lever, n. This lever being mounted to the
same shaft, o, whereto the arm, p, is attached, this allows the sliding rod, q, to
follow the tendency of the spring, r, and to slide forwards. A stop, u, mounted
to the rod, g, thereby engages behind the arm, s, having its fulcrum at, t, and pro-
vided with the bearing, v, of the one roller. Thus this roller recedes from the
.other one, whereby the mutual grinding-off of both rollers is prevented.
The arm, l, which is pulled in its proper position by the spring, w, after being
released from the knocker, does not rest in a fixed bearing, but is pivotted in the
arm, x, of the angle lever xy, the arm, y, of which is provided at its end with a
nut, into which engages the screw spindle, z, resting in the bearings j. Con-
sequently the arm, x, will be lowered when the arm, y, is moved backwards by
turning the spindle, z, in the corresponding direction; but as the pawl, m, is
pivotted in the arm, x, and supports the combination of the levers, n and p, which
acts upon the rod, g, and thereby also upon the mutual position of the rollers to
each other, a larger distance between both rollers will be produced when moving
the arm, y, backwards by turning the spindle, z, in the corresponding direction,
us also the rollers will be approached to each other when turning the spindle in
the opposite way.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
First. In roller-mills, the combination of the hopper a, flap b, shaft e, lever c,
counterweight d, finger f, angle lever g h provided with the pawl i, and the
knocker with the arm l, ratchet m, lever n, shaft o, arm p, rod q provided with
the stop u, spring r and lever & supporting the bearing of the one roller,
substantially as set forth.

page_text: Second. In roller-mills the combination of the screw spindle z, angle lever a y,
ratchet m, lever n, shaft o, arm p and rod q with the lever & supporting the
bearing v of the one roller, substantially as and for the purpose specified.
