IMPROVEMENTS IN MACHINERY FOR REMOVING THE PEEL OR SKIN FROM POTATOES AND OTHER VEGETABLES WHILE MASHING THE SAME
Year: 1877

page_text: LETTERS PATENT to Carl Dressler, of Schierstein-on-the-Rhine, Hesse-Nassau,
Germany, for the Invention of "IMPROVEMENTS IN MACHINERY FOR REMOVING
THE PEEL OR SKIN FROM POTATOES AND OTHER VEGETABLES WHILE MASHING
THE SAME."
PROVISIONAL SPECIFICATION left by the said Carl Dressler at the Office of
the Commissioners of Patents on the 15th September 1877.
CARL DRESSLER, of Schierstein-on-the-Rhine, Hesse-Nassau, Germany. " IMPROVE-
MENTS IN MACHINERY FOR REMOVING THE PEEL OR SKIN FROM POTATOES AND
OTHER VEGETABLES WHILE MASHING THE SAME."
This Invention relates to machinery for removing the peel, skin, or rind from
potatoes and other vegetables while the same are being mashed, and comprises
various improvements in the construction and arrangement of the parts of the
mechanism, as herein-after set forth.
According to the said Invention I construct a press-box frame, in which is placed
à perforated press plate, the bottom of which is provided with cylindrical iron bars
of a conical form. The said bars are rivetted or otherwise securely fastened on
bearers extending through the press at suitable distances apart, and of a thickness
preferably somewhat lesser than this distance. The said press plate is so arranged
in the frame that the same by means of a projecting piece placed at the side during
the descent is pushed slightly to one side, and during the ascent of the press by
springs is again brought back into its first position, whereby and by means of a flat
wire gauze the mass of potatoes or other vegetables is peeled.
This apparatus will be found very advantageous in the case of inferior waxy
potatoes.

page_text: After the potatoes or other vegetables are boiled or steamed they are cut through
and spread out on the press plate, on which the flat wire gauze has been previously
laid, so that the cut side lies undermost, then they are pushed into the press, and
squeezed out, while a second and similar press box on the opposite side of the machine
is filled. By means of these two boxes the operation of the said machine may be
carried on continuously, and with great rapidity.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Carl Dressler in the Great Seal Patent Office on the 13th March
1878.
CARL DRESSLER, of Schierstein-on-the-Rhine, Hesse-Nassau, Germany. "IMPROVE-
MENTS IN MACHINERY FOR REMOVING THE PEEL OR SKIN FROM POTATOES AND
OTHER VEGETABLES WHILE MASHING THE SAME."
This Invention relates to machinery for removing the peel, skin, or rind from
potatoes and other vegetables while the same are being mashed, and comprises various
improvements in the construction and arrangement of the parts of the mechanism as
herein-after set forth.
My Invention is illustrated in the accompanying Drawings, in which,-
Figure 1 is a front elevation, partly in section, of a machine embodying the said
improvements.
Figure 2 is a longitudinal section of the said machine.
Figure 3 is a plan, partly in horizontal section, of the same.
Figures 4 to 12 shew portions of the said machine detached, that is to say,
Figure 4 is a sectional view, and Figure 5 a plan of the press-box frame; Figure 6
is a sheet of wire gauze; Figures 7 and 8 are sectional views, and Figure 9 a plan
of a set of iron bars; Figures 10 and 11 are sectional views; and Figure 12 a plan
drawn to an enlarged scale of another set of such bars slightly modified.
Like letters indicate the same parts throughout the Drawings.
a is a press-box frame, wherein is placed a perforated plate, the bottom of which
is provided with iron or other bars a', supported by a frame or bearers, and which
bars are in transverse section of a cylindrical form, as shewn in Figure 7, or of a V
or conical form, as shown in Figure 10. The said bars are rivetted or otherwise
securely fastened on the said frame or bearers at suitable distances apart, and are of
a diameter or thickness preferably somewhat less than this distance. The movable
plate b of the press is provided with a projecting piece c, which moves vertically,
and is so arranged and operated in combination with the frame a that the said pro-
jecting piece during its descent so acts on the said frame as to give it a lateral
motion, and during the ascent of the projecting piece c the said frame is actuated by
the springs & in the opposite direction, that is to say, the said frame receives a lateral
reciprocating motion. The said press plate is provided with a sheet of wire gauze,
shewn detached in Figure 6.
The operation of this machine is as follows, that is to say :--After the potatoes
or other vegetables are boiled or steamed they are cut through and spread out on
the plate of the press box a, on which the flat wire gauze has been previously laid,

page_text: so that their cut or flat side lies undermost; then this press box is pushed into the
press, and the vegetables contained therein are squeezed or mashed by the pressure
of the same applied in the usual or any suitable manner, while a second and similar
press box, previously arranged on one side of the machine, as shewn in Figure 2, is
in like manner filled with potatoes or other vegetables. By means of these two
boxes the operation of the said machine may be carried on continuously and with
great rapidity and economy, and by the reciprocating movement of the aforesaid
frame and the effect of the wire gauzes or sieves the said potatoes or other vegetables
are separated from their peel, rind, or skin, and discharged into a box for any other
suitable receptacle in such a condition that they require no cutting previous to their
storage or use.
This apparatus will be found very advantageous in the case of inferior waxy
potatoes.
Having thus fully described the said Invention, and the manner of performing
the same, I wish it understood that I claim, the combination with any suitable press
of the press-box frame with its perforated bottom provided with bars and the wire
gauze, the vertically moving projecting piece, and the springs, arranged and operating
as above set forth and for the purposes specified.
In witness whereof, I, the said Carl Dressler, have hereunto set my hand and
seal, this Ninth day of March, in the year of our Lord One thousand eight
hundred and seventy-eight.
Signed, sealed, and delivered by the
above-named Carl Dressler, at
Frankfort m Germany, this
Ninth day of March 1878, before
me,
C. LANTEREN,
British Vice-Consul.
CARL DRESSLER. (L.S.)
