WILLIAM R. LAKEY, OF DENTON, TEXAS.
MILLING-MACHINE.Specification of Letters Patent. Patented Feb. 3,1914.
Application filed July 23, 1912. Serial No. 711,145.To all whom it may concern:
Be it known that I, WILLIAM R. LAREY,
a citizen of the United States, residing at
Denton, in the county of Denton and State
5 of Texas, have, invented a new and useful
Milling-Machine, of which the following is
a specification.
This invention has reference to improve-
ments in milling machines and its object is
10 to provide a machine which will more thor-
oughly remove dirt and other substances
which should not follow the stock than has
heretofore been the case, and carry the re-
moved material to the dust collector for fur-
15 there treatment, and which will cool and
partially dry the stock, thereby aiding in
the subsequent grinding and bolting to a
commensurate extent, this greatly improv-
ing the quality of the product and also in-
20 creasing the yield and profits.
In accordance with the present invention
the direction of travel of the stock is broken
many times, while the fall of stock from
one directing changing means to the next
25 is short, thereby admitting of strong air
currents without liability of carrying away
any parts of the falling stock except those
which it is desirable should be extracted by
such air currents. In the present machine the
30 air cu-rents traverse the falling stock dur-
ing each fall, while the parts are so dimen-
sioned as to prevent any change in the ac-
tion of the air currents on the dropping
stock at different parts of the apparatus, so
35 that there is no liability of uneven action of
the air currents and consequent escape of
some portions of the removable parts of the
stock being carried by said stock beyond the
action of the air currents.
40 The invention will be best understood
from a consideration of the following de-
tailed description taken in connection with
the accompanying drawings forming a part
of this specification, with the understanding
45 that while the drawings illustrate practical
forms of the invention it is susceptible of
other practical embodiments, wherefore the
invention is not confined to any strict con-
formity to the showing of the drawings
50 but may be changed and modified so long
as such changes do not mark any material
departure from the salient features of the
invention.
In the drawings Figure 1 is an elevation
56 of a. machine designed to break stock. Fig.
2 is a section on the line 2-2 of Fig. 1.Referring to the drawing there is shown
a casing 1 through the center of which there
extends an air trunk 2 which is assumed to
be connected by a pipe 3 with a suction fan, 60
the latter not being shown, but being com-
monly employed in connection with ma-
chines of the character of the present in-
vention. Within the pipe 3 is a cut-off
valve 4 which may follow the usual prac- 65
tice. The top of the casing 1 on opposite
sides of the air trunk is entered by inlet
ducts 5, 6, respectively, while the other or
bottom end of the casing is contracted, as
indicated at 7, to discharge openings 8, 70
while extending across the discharge por-
tion of the casing is a support 9 crowned by
a deflector 10 in the form of an inverted V
with its apex substantially central to the air
trunk and at approximately the lower end 75
of the latter. Extending from opposite
sides of the air trunk are spaced baffles 11
and in alternate relation to these baffles are
other baffles 12 extending from the corre-
sponding faces of the casing 1. The baffles 80
all decline at a suitable angle and their in-
terspersed free edges are arranged one be-
low the other in line with the inlets 5 and 6,
respectively. Where each baffle 11 joins the
air trunk there is an opening or port 13 85
entering the air trunk and where each
baffle 12 joins the corresponding face of the
casing 1 there is an opening or port 14, the
latter being provided with an adjustable
cut-off or valve 15 which may be held in ad- 90
justed positions by fastening nuts 16 or
other suitable devices. Let it be assumed
that air is being withdrawn from the trunk
2 through the pipe 3 and consequently air
is entering the trunk through all the ports 95
13. Stock is assumed to be entering the
casing through the inlets 5 and 6. The
stream of stock strikes the uppermost
baffles 12 and by them is deflected on to the
next succeeding baffles 11 and falls freely 100
between these two baffles in a stream of ap-
propriate size. From the uppermost baffles
11 the stream of stock is directed on to the
second set of baffles 12, thence its direction
of flow is diverted to the second set of 105
baffles 11 and so on throughout the series of
baffles until finally falling from the lower-
most baffles 11 the streams find their way to
the discharge openings 8 and to a conveyer
or other suitable means, whereby the 110
cleaned stock is conveyed to a suitable point
of disposal. Underneath each baffle is a1,085,92.1.
