Shaft 58 is held against forward axial movement at a rear

The clutch element 164 is in turn secured against forward

The rear driving clutch element 164 is mounted for ro

shaft and comprises a spur gear 172 at a rear end por

clutch surface 174. The spur gear 1'72 meshes with and
is driven by a gear `176 which is supported for rotation
about a sleeve bearing 17S mounted on the aforemen

gear 176 is connected with a sprocket 180 by means of a
suitable screw 182 and by a retaining pin 184. The
sprocket 1180 is also mounted for rotation on the sleeve
about the shaft 58 and engages a ring 240 adjacent the
front face of the front clutching element 218 to urge
the said element rearwardly along the shaft 58 and Sleeve

in FIG. l.
In the first or front position of the central clutch ele

a toothed surface 216 on a front driving clutch element
21d. The front driving clutch element 218 also includes
an integrally formed spur gear 2211` and said element is
mounted for rotation about a- sleeve bearing 222 on the
shaft 58. Recalling that the shaft 515 and its associated
parts are revolved `bodily about the axis 22, it will be
apparent that rotation of the spur gear 220 about the
sleeve bearing 222 and the shaft 5S can be convenient
ly effected by engagement of the said gear with a sta

cylindrical housing member being in turn supported by

of revolution.
As shown, -a means for shifting the rods 210, 210
comprises a partially circular and generally horseshoe
shaped cam 246 disposed within the cylindrical housing
226 in an inverted attitude. The cam 246 is preferably
supported by means of three triangularly spaced studs

a suitable `aperture 25th in the upright frame member `

Operation
Dimensions of parts, gear and sprocket wheel ratios,
and other variable factors have been selected in the em
bodiment of the invention shown to provide for opera
tion of the fiber transfer mechanism resulting in the
provision of a continuous layer of fibers of uniform
thickness on the sprocket chains d6, `¿i6 of the conveyor
i6. Accordingly, this mode of operation will be de
scribed, but it will be understood that various other modes
of operation of the mechanism can be readily provided
for as required by the characteristics of other fiber re-«
ceiving devices or conveyors and the characteristics of
various brush making machines or the like.
As mentioned above, the path of revolution of the
transfer wheels i8, Il@ includes an upper portion which
constitutes a loading zone and a lower portion which
constitutes an unloading zone. It will be apparent that

which fiber discharge or unloading operation occurs. The
dimension or distance U is equal to approximately one
half the dimension or distance L.
To provide for discharge of all of the fibers from the
notches of each transfer wheel in the distance U, each of
said transfer wheels is rotated at the unloading zone so
as to have a substantially pure rolling movement with
respect to the conveyor f6 in a direction opposite to the
direction of movement of the conveyor. It will be re
called that the upper runs of the sprocket chains 46, 46
move rightwardly at .a speed N2 which is substantially
equal to the peripheral or surface speed N1 of the disc
2d. The peripheral surface of the disc 24 moves gen
erally leftwardly adjacent the said upper runs of the
sprocket chains 46, ¿i6 and the transfer wheels 18, 18
are rotated in a counterclockwise direction as mentioned
previously. To provide for the desired rolling movement
of the transfer wheels, the predetermined speed at which
the loading Zone comprises that portion of the path of
the wheels 1S, i8 are rotated during passage through the
revolution wherein the notches of the transfer wheels
18, ld are loaded with fibers from the bottom of the 20 unloading zone by the driving connection between the
central and rear clutch elements E94, 194.- and 16d, 164
mass of fibers l2 by operation of the associated slicing
is such that the wheels have a peripheral or surface
knives or knife edges 9d, 9d. Similarly, the unloading
speed N4 approximately twice the disc surface speed N1
zone comprises that portion of the path of revolution of
and the conveyor speed N2. Thus, it will be seen that
the transfer wheels wherein fibers are discharged from
each transfer wheel i3 will complete approximately one
the wheel notches onto the conveyor lo. The knives or
revolution in the distance U so as to discharge .all of the
knife edges 94, 94 are operative to load ñbers into the
fibers in its notches.
notches of associated transfer wheels substantially
From the foregoing, it will be apparent that the length
throughout the arcuate distance L measured along the
of a layer of fibers deposited on the upper runs of the
peripheral surface 3S of the disc 2d and generally lon
gitudinally between the inner surfaces of the side walls 30 chains ed, 46 will be substantially equal to the length of
the layer as initially sliced from the bottom of the mass

represents the initial length of the layer of fibers sliced

in the notches of a transfer wheel by each knife or knife

edge 94. The layer length L, as will be explained pres
move rigI itwardly through approximately' an equal dis
tance. Since the distance U is approximately equal to
one-half the distance L, the final length of the layer of
fibers deposited on the chains will be substantially equal
ently, is maintained substantially constant while the ñbers
are carried on the fiber `wheels and even after the fibers
have been deposited on the conveyor le.
to the distance L. It is to be observed also that the dis
ln the form shown, the transfer wheels 1S, i8` have
circumferences substantially equal to the distance L and 40 tiibution of the individual fibers in each layer of fibers
the wheels are rotated in a counterclockwise direction as
stated. During passage through the loading zone, the
speed of rotation of said Wheels is such that a substan
tially pure rolling movement of the wheels along the
bottom `of the mass of fibers l2 is provided for. Stated
deposited on the conveyor is substantially the same as the
original distribution of fibers in the layer as it is sliced
from the bottom of the mass of fibers l12. Thus, a layer
of substantially uniform thickness and of known and
equal length is deposited on the conveyor chains iby each
a predetermined speed which effects a surface or pe
transfer wheel.
In order that a continuous layer of fibers may be de
posited on the upper runs of the conveyor chains 46, d6,
it is of course necessary that adjacent ends of succeeding
ripheral wheel speed N3 which is substantially equal to
layers of fibers be disposed accurately in abutting rela
differently, the aforementioned driving connection be
tween the front and central clutch elements 2id, 2l@ and
i941, 194 provides for rotation of the transfer wheels at
the aforesaid peripheral or surface speed N1 of the disc
2d. Thus, each transfer wheel completes approximately
one revolution in passage through the loading Zone L and
substantially all of its notches ‘74, 7d- are filled, the length
of the layer of fibers deposited in the notches being sub
stantially equal to the distance L. Said layer length
obviously remains unchanged while the fibers are car
ried by the wheel from the loading zone to the unloading
zone at a lower portion of the path of revolution of the
tionship. Provision is made for a continuous layer of
fibers on the upper runs of the conveyor chains in the
spacing of the transfer wheels i8, f3. The distance D
between the center lines of adjacent transfer wheels meas
ured along the arcuate peripheral surface 33 is substan
tially equal to the aforementioned distance L. Consider

The number of fibers in each layer of ñbers deposited
on the upper runs of the sprocket chains d6, 46 may of
course vary slightly. Uniformity among the layers of
fibers Will, however, be sufficient for the intended purpose
and it can fairly be said that each layer of fibers Will
contain a known and selected quantity of fibers. In order
to vary the number or quantity of fibers in each layer and
to thereby vary the thickness of a continuous layer of
fibers on the conveyor, it is only necessary to select ap
propriate front and rear Washers 64 and 66 for each
transfer Wheel of Wheel unit 18. As previously mentioned,
interchangeable pairs of Washers of various sizes are pro
vided to enable the selection of a desired notch depth and
