Improvement in Dough Shaping Machine.
I, FRITZ DÜHRKOP, of 550 East 82nd Street, New York City, New York,.
United States of America, Manufacturer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described aud ascertained in and by the following statement:-
This invention relates to a machine for forming fermented dough into cylindrical
bodies which are subsequently cut up into the lengths desired for the bread. Thus
the laborious process of shaping the dough by hand is dispensed. with.
In the accompanying drawings
Fig. 1 is a vertical section of the machine.
Fig. 2 an elevation partly in section thereof, and
Fig. 3 a cross section on line 3, 3, Fig. 2.
The letter a, represents the upright cylindrical shell of the machine, preferably
composed of two bolted sections, of which the lower section tapers from top to.

convolutions and driven from power pulley d. This pulley by cone pulleys d', d₁,.

discharge end with a hollow ring f, perforated at its inner face and connected to a
water tank f. The rings are surrounded by a covering g of chamois leather or
similar soft porous material, that constitutes a lining for the rings, and is moistened
by the water that percolates through the perforated inner face of the same.
The dough is thrown into the top of shell a, and will by its own weight fall upon
the screw, that forces it out through the nozzles. On passing the soft, moistened
coverings g, of rings f, the dough will be lubricated, so that it will not stick or
pack, but will leave the machine in a smooth, continuous and homogeneous mass..
The cylinders of dough A that are discharged from the nozzles will be deposited
upon the feed aprons e¹, which carry them forward, so that they may be cut up into
the desired lengths.
One of the principal advantages of this machine is that the dough is fed in the
direction of its gravity and that no antagonistic forces act upon it while passing
through the nozzles and lubricating rings, until it is deposited upon the feed.
table.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of an upright shell having a downwardly extending
discharge nozzle at its lower end, with a vertically hung conveyer screw within the
shell and a laterally projecting feed apron beneath the nozzle, substantially as
specified.
2. The combination of an upright shell having a downwardly extending discharge
nozzle at its lower end, with a vertically hung conveyer screw within the shell, a
perforated lubricating ring at the discharge end of the nozzle, and a leather lining
within said ring, substantially as specified.
