No. 23814.—11th December, 1907.—THE AMERICAN LINEN
COMPANY, a corporation duly organized and existing under
the laws of the State of Maine, and having its principal place
of business at No. 152 Temple Street, New Haven, Connecticut,
United States of America (the assignees of Clayton Guy
Cooke, of said New Haven). Flax-machines.

Extract from Specification.—Referring to the drawings
for a more particular description, the parts designated by the
letters A and A¹ represent the bed and standard of the ma-
chine, and B a portion of the feed-tray. Mounted on the
bed A, near the feed-tray B, is a pair of cylindrical feed-
rollers 1 (Fig. 3). Near the feed-rollers is a pair of straight-
fluted breaker-rolls 2, and beyond the breaker-rolls are two
pairs 3-3 of spirally-fluted breaker-rolls. 4 designates a
supplemental pair of straight-fluted breaker-rolls, and 10 the
tables or trays between the various above-named pairs of
rolls. The shaft 50 of the upper of each of said pairs of rolls
is journalled in a journal-box 51 having a vertical sliding move-
ment in a bearing 52, as shown more particularly in Fig. 12.
In the bearing 52 is a vertical socket 53, containing a spring
54 adapted to bear on the upper side of the journal-box 51.
A screw 55 is provided to vary the tension of the spring 54.
By this means the upper row of each pair of breaker and feed
rolls is capable of a limited movement to allow for the varying
thicknesses of straw passing between the rolls, and to avoid
injury to the machine from hard substances which are some-
times found in the straw. The rolls 1, 2, 3, and 4 are driven
from a vertical shaft 6 by means of a bevel gearing 5 (Fig. 5)
carried on the shaft of the lower of the pair of rolls 2. As shown
in Fig. 1, the shaft of the roll 2 is provided on the other side
of the machine with a pinion 7, which meshes with a pinion
56 on the shaft of the upper of the pair of rolls 2. The pinion
7 meshes also with gears 8 adapted to engage pinions 57 on
the shafts of the lower rolls of the pairs 1 and 3, which pinions
57 in turn drive pinions 58 on the shafts of the upper of the
pairs of rolls 1 and 3. By means of gearing 59 and pinions
60 and 61 the other rolls 3 are rotated. A further gear 62
and pinions 63 and 64 transmit the rotary movement of the
shaft 6 to the rollers 4 in similar manner. The vertical shaft
6 is driven from a horizontal shaft 65, which is the main
driving-shaft of the machine.

No. 23815.—11th December, 1907.—ALBERT ZABRISKIE,
of 141 Ward Street, Paterson, State of New Jersey, United
States of America, Mechanical Engineer. Improvements in
fibre-preparing machines.

Extract from Specification.—The general type of machine
to which I have illustrated my improvements applied com-
prises two scutching-wheels 10, 11, located one after the other
in the horizontal plane, and having their axes parallel but
offset so that the peripheries of said wheels overlap when
viewed axially, a pair of conveyor-chains 20, 22, for serving
the first scutching-wheel 10, and a second pair of conveyor-
chains 21, 23, offset horizontally from the first pair of chains,
for taking the partly cleaned leaves from said first pair of
chains and presenting the same to the action of the second
scutching-wheel 11. The object of my improvements is to
furnish a machine of the general class specified, simple in
construction, and which may be operated with a relatively
small expenditure of power and with a minimum waste of
the fibre of the leaf. With these objects in view, I fix the
first scutching-wheel 10 on a suitable shaft 12, and which
shaft has its bearings at 14, 16, in frames 2, 3 respectively.
Said shaft 12 is provided with a pulley 6 to which power
may be supplied by means of a belt (not shown) directly
from any suitable source of power. The second scutching-
wheel 11 is fixed on shaft 13, mounted in bearings 15, 17, 19,
in frames 3, 4, and rail 5 respectively. Said frames 2, 3, 4
are fixed to and are upstanding from bed-plate 9 of the ma-
chine, while rail 5 extends horizontally from frame 2 to frame
3, and is fixed thereto. Said shaft 13 is provided with a
pulley 7 to which power may be supplied by means of a belt
from any convenient source of power, such as that from
which scutching-wheel 10 is driven. Said scutching-wheels
10, 11, are provided with beating-blades 100, 110, suitable
for coaction with concave plates or shoes 30, 31, all respec-
tively. As said shoes 30, 31 are duplicates, a description of
one will suffice for both. Shoe 30 has the contour of its
working-face throughout the major part of its length sub-
stantially concentric with the periphery of its scutching-
wheel 10, but the upper part of the face of said shoe is of
peculiar and novel contour. Heretofore, according to the
best practice in this art, there has been a distinct line of
demarkation of the beginning of engagement of the scutching-
blade and shoe, whereby the action of removing the pulp of
the leaf has been so abrupt and harsh as to cause a material
and wasteful loss of fibre by breakage at said line of begin-
ing of coaction of scutching-blade and shoe. Also, said
distinct line of demarkation between cleaned and uncleaned
leaf is a fruitful source of waste at the second scutching-
wheel, as that wheel is thereby required to commence its
work abruptly, thus causing injury to the fibre. In my
improved machine I have eliminated these objectionable
features by connecting the top edge 108 of shoe 30, said edge
being relatively remote from the path of scutching-blades 100,
with the concentric portion 109 of said shoe by a plane or
curved surface 300, preferably tangent to said concentric
portion 109, where it merges therewith. I thereby obtain a
graduated opening as 105 between the face of the shoe 30 and
the path of the operative edge of the scutching-blade.
