DISINTEGRATING, AND SEPARATING MINERALS, GRAIN, FIBROUS MAIERIALS, AND
OTHER SUBSTANCES" A communication from abroad by Andrew Burrell Lipsey,
of West Hoboken, New Jersey, Joseph Bouton Crosby, of the City and State of
New York, Purdy Dickerson Barnhardt, of Forestville, New York, and Samuel
Belding Mower, of the City and State of New York, all in the United States of

This Invention relates to improvements in machinery for pulverizing, disinte-
giating, o reducing to powder ones, stones, wheat, and other substances, and
comprises means for regulating the feed of materials to such machinery, also for
separating fine and light from coarse and heavy particles of material delivered from
such machinery, also renewable shoes for beaters in such machinery, and knives or
cutters for facilitating the disintegration of fibrous materials
One improvement consists in the combination of a series of chambers of succes-
avely larger diameters, arranged one outside or beyond the periphery of another,
and series of beaters for revolving therein, whereby an extremely compact, simple,
and serviceable pulverizing or disintegrating machine is produced
Another improvement consists in the combination with a chamber provided with
a series of beaters of a chamber of larger diameter communicating with the former,
and provided with a series of beaters revolving in the same length of time as those
in the smaller chamber, and consequently moving at a greater speed, producing a
partial vacuum, and drawing from the smaller chamber the lighter particles of the
material therein pulverized or disintegrated, whereby we produce a very simple and
ונג..

small amount of power
Another improvement consists in the combination with a chamber provided with
a series of beaters of a chamber of larger diameter communicating directly with the
smaller chainber, and provided with a series of beaters supported on the same shaft
as those of the said smaller chamber, and revolving in the same length of time,
whereby we produce a simple, exceedingly compact, and very superior pulverizing
or disintegrating machine
Another improvement consists in the combination of two or more chambers com-
municating one with another, provided each with a series of beaters for revolving
therein, and also provided with lips overlapping the beaters of each chamber, which
communicates with another chamber, whereby material to be pulverized or disin
tegrated is prevented from passing out of one chamber into another except at the
proper place
Another improvement consists in the combination with a series of chambers suc-
cessively of large diameters, provided with beaters for revolving therein, and with
lips overlapping the beaters of each chamber, which communicates with another
chamber, and with offsets arranged at the inner ends of the beaters for deflecting
material escaping from one chamber into the middle of the next, so as to present it
properly to the beaters therein
Another improvement consists in the combination with a chamber and beators or
then equivalents for effecting the pulverization or disintegration of material therein
of a long hub for supporting such beaters or their equivalents, extending out beyond
said chamber, whereby oil or other lubricant applied to the shaft, by which such
beaters or the equivalents are carried, is prevented from entering the chamber so as
to impair the quality of materials pulverized or disintegrated thei ein
Another unprovement consists in the combination with a pulverizing or disinte-
grating machine, and an inlet for supplying material to be pulverized or disintegrated
and air or its equivalent thereto, of a throttle for the inlet, providing for simul-
taneously regulating or entirely shutting off by the same means both the supply of
material to be pulverized or disintegrated, and an or its equivalent when desirable.
Another improvement consists in the combination with a pulverizing or disinte-
grating machine of a laterally oscillating feed shoe or trough, preferably capable of
adjustment at different angles to the horizontal, and deliving motion fiom the
driving shaft or other suitable shaft of the machine, whereby provision is afforded
for automatically regulating the feed of material to be pulverized or disinte-
grated to suit the speed at which the machine is working, and thus lessening the
danger of the material being fed too freely, and choking the machino
Another improvement consists in the combination with the supply passage of a
pulverizing or disintegrating machine of means for feeding or supplying the same,
and a governor or its equivalent for actuating the feeding or supplying device, so
that the feed of the material to be pulverized or disintegrated will always be com-
mensurate with the speed at which the machine is working, and will be automatically
stopped when the machine is working at so slow a rate of speed that the material if
fed into it might choke it
Another improvement consists in the combination with a pulverizing or disinte-
grating machine of an outlet provided preferably at the lower part with an opening
or openings, and capable of being adjusted axially by swinging at different angles
to provide for separating the finer and lighter from the coarser and heavier particles
of the pulverized or disintegrated material in delivering it from the machine.
Another improvement consists in the combination with a beater extending longi-
tudinally from the side of a disc or spider of a renewablo shoe fitting or lapping
over the face, inner edge, and outer end of such beater, a dowel or projection on the
outer end of said beater fitting a cavity in the contiguous portion of the shoe,
and a rivet, bolt, or equivalent device at the inner end of the shoe securing it to
the aforesaid disc or spider, whereby provision is afforded for properly securing the
shoe in place without perforating and thereby weakening the beater transversely.

page_text: Another improvement consists in a beater or the equivalent part of a pulverizing
or disintegrating machine provided with series of knives or cutters, preferably made
in pairs, extending from single shanks, whereby increased facilities are afforded for
the disintegrating of wood and other fibrous materials
Other improvements consist in details of construction.
