FLAKING MACHINE FCR FISH AND THE LIKE
Andrew L. Christiansen, Willowbrook, Calif.
Application March 14, 1939, Serial No. 261,744
23 Claims.

My present invention relates to a machine or
apparatus for, and to a method of, dividing a
product, particularly such as a ñbrous, glutinous
or similar food or other product, and particu
larly for dividing or separating the same into

The operating power of my machine may be
supplied by a motor 4 I, which may be supported
375'
on the frame I. The shaft 4Ia of the Vmotor is
shown as connected directly to the shaft I3 of the
grinder~ On the shaft 4 la of the motor is a sheave
42 which is shown connected to a large sheave 43
by means of a belt 44. This sheave 43 is mount
ed on a shaft 45 having small sheaves 46 and 41
mounted thereon. 'I‘he sheave 46 is connected,
by a belt 48, to a sheave 49 mounted on a shaft
50 upon which the pinion 2B is mounted. The
sheave @II'IY is connected, by a belt 5I, to the sheave
34 on the shaft 28 carrying the smaller drum or
screen.
It will be noted that the axis of the shaft 5i!A
may be at a slight angle to the axis of the motor 50
4I. The angularity of the axis of the shaft 28
may vary constantly. For these reasons, I have
shown belt connections between the motor 4I and
the drives for the drums 2 l_ and 22. This struc
ture, however, is to be understood as not con
ñned to such drives.

product, is discharged into the feed end of theV
