CARL GUSTAV BAUMGARTEN, OF SWEET HOME, TEXAS.
MAT FOR PRESSES.
SPECIFICATION forming part of Letters Patent No. 695,266, dated March 11, 1902.
Application filed October 12, 1901 Serial No. 78,420 (No model.)To all whom1 it may concerRh:
Be it known that I, CARL GUSTAV BAUM-
GARTEN, a citizen of the United States, resid-
ing at Sweet Home, in the county of Lavaca,
5 State of Texas, have invented certain new and
useful Improvements in Mats for Presses;
and I do hereby declare the following to be a
full, clear, and exact description of the in-
vention, such as will enable others skilled in
io the art to which it appertains to make and
use the same.
This invention relates to presses in general,
and more particularly to the mats thereof;
and it has for its object to provide a mat par-
15 ticularly designed for use in expressing oil
from cotton-seed or other oil containing vege-
table matter, a further object of the inven-
tion being to provide a construction which
may be easily cleaned and will be efficient in
20 operation.
In the drawings forming a portion of this
specification, and in which like numerals of
reference indicate similar parts in the several
views, Figure 1 is a perspective view show-
25 ing the mat. Fig. 2 is a perspective view
showing the back plate of the mat. Fig. 3 is
an elevation showing the perforated metal
plate that is disposed upon the back plate.
Fig. 4 is a view showing the press-cloth. Fig.
30 5 is a view showing the exterior woven-wire
sheet. Fig. 6 is a horizontal section taken
longitudinally through an intermediate mat.
Fig. 7 is a section on line 7 7 of Fig. 6.
Referring now to Fig. 1 of the drawings,
35 there is shown a single-faced mat comprising
a back plate 5, which-is provided with the up-
per and lower side flanges 6 and 7 and the end
flanges 8 and 9 on one face, the mat in prac-
tice being stood on one edge with the flange
40 6 uppermost and flange 7 lowermost. Ver-
tically of the active face of the plate 5 are
formed the ribs 10, which extend from the
upper rib 6 to points near to-the lower rib 7,
from which latter they are separated by slight
45 interspaces, as shown. The upper or inner
face of the flange 7 is concaved, so that oil
falling thereon will run to the center thereof,
and at the middle of the under side of the
plate 5 is formed a channel 12, one end of
50 which communicates with the inclosure of the
marginal ribs of the plate, while the other endopens through the bottom edge of the plate,
so as to direct oil to a longitudinal opening
20 in the bottom of the press-box in which
the mat is used. Against the ribs of the 55
plate 5 is disposed the perforated metallic
plate 13, which is a backing-plate and against
which is disposed the press-cloth 14, -upon
which in turn is disposed the metallic screen
or cloth 15, the several parts being held to 6o
the plate 5 by means of bolts 16, engaged with
the plate and with the longitudinal'strips 17
and 18, secured against the wire-cloth at the
upper and lower edges. of the mat.
To prevent passage of the material under 65
treatment from between the mat and the next
cooperating mat through the opening 20 in
the bottom of the press-box, the plate 5 has a
foot 19, which extends at right angles thereto
and is secured against its under side in posi- 7o
tion to lie in the slot 20 and project beneath
the cooperating mat.
It will be understood that an intermediate
mat has both of its side faces provided with
the ribs, against which are disposed the back- 75
ing-plates which support the press - cloths
and screens, the mat herein shown being an
end mat.
In practice modifications of the specific
construction shown may be made, and any 8o
suitable materials and proportions may be
used for the various parts without departing
from the spirit of the invention.
What is claimed is-
1. A mat for presses comprising a back 85
plate having a longitudinal flange at its lower
edge having its upper face concaved, and
means upon the face of the plate above the
flange and coacting with the flange to receive
the foraminous portion of the mat and hold 90
it in spaced relation to the face of the plate.
2. A mat for presses comprising a back
plate having vertical ribs and enclosing up-
per, lower and end flanges, said ribs extend-
ing from the upper flange to near the lower 95
flange, the lower flange having a concaved
upper face, and the plate having a passage
therethrough arranged to conduct liquids
from the upper face of the lower flange through
the .lower edge of the plate, aperforated plate xoo
disposed against the flanges and ribs, a press-
cloth disposed against the perforated plate,
