LETTERS PATENT to Frank Wirth, of the Firm of Wirth and Company, Patent
Solicitors, at Frankfort-on-the-Main, in the Empire of Germany, for the
Invention of "IMPROVEMENTS IN CARDS USED IN COTTON MACHINERY.”
communication from Egidi Moog, Foreman Spinner, a person resident at
Oggersheim, in the Empire of Germany.
Sealed the 28th February 1878, and dated the 5th September 1877.
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office
of the Commissioners of Patents on the 5th September 1877.

FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort-on-the-Main, in the Empire of Germany. IMPROVEMENTS IN CARDS USED IN
COTTON MACHINERY." [A communication from Egidi Moog, Foreman Spinner, a
person resident at Oggersheim, in the Empire of Germany.]
On all carding engines there is a greater or lesser space left unoccupied between
the last roller and scraper, because the cover and roller at this point do not press
against the centre of the drum, and therefore cannot be regulated. At this
unoccupied place I attach my new clearing apparatus; this apparatus catches and
takes off knots and husks still remaining in the cotton.
In the accompanying Drawings my apparatus is shewn partly in side elevation
and partly as seen from underneath.
a is a portion of the periphery of the chief drum; b, a portion of the periphery
of the scraper; c, the last roller; d, one of the two cast-iron sides of the apparatus;
e, wooden rails let into the side pieces d and going across the whole width of the
carding engine, to which they are fastened by the steel rails f, which also serve to
support them. These steel rails are really the working portion of my Invention ;
they are about 0-5 millimetres thick, and 3 to 4 millimetres wide, and well hardened
to prevent their wearing out, and are provided with a single dull edge on the side
D

the rails into the catching tin i. The rails are placed at a tangent of 45 degrees to
the periphery of the carding drum; e¹ is a wooden connecting piece, partly to fill
out the empty space between the drum and the scraper, and partly to serve as a
fastening for the receiving tin i; lare regulating screws to regulate the steel rails
on account of the different lengths and qualities of cotton; these rails cannot be
fixed, but the proper distance from the card has to be found by trials. By the use
of these screws, one or all of the rails can be regulated while the machine is at
work, with the greatest ease; m are wood screws screwed into the wooden lining
between the card and the card shields g, and serve as general supports and fixings
for the apparatus; n are bolts fastened into the side shields of the card, and serve
to regulate the whole apparatus with the help of the carriers k; g is one of the side
shields of the card, upon which a wooden dust cover is screwed by means of its
supports quite across the apparatus.
This apparatus can be used in any old carding machine without any alterations,
as it is only necessary to screw the bolts on into the side screen, and to catch the
apparatus upon them.
My present Invention is not to be mixed up with an apparatus which has some
outward resemblance with it, namely, the three cornered iron bars introduced under
some cards and scraping rollers. These bars do not clean, but only let the dirt fall
through, while preventing the cotton-from doing so; without these bars, the dirt
would fall through all the same, but a great deal of cotton with it.
My apparatus serves to detach the impurities from the cotton by means of the
steel rails, and to catch the former; without my apparatus the impurities would
stick to the cotton.

FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort-on-the-Main, in the Empire of Germany. "IMPROVEMENTS IN CARDS USED IN
COTTON MACHINERY." (A communication from Egidi Moog, Foreman Spinner, a
person resident at Oggersheim, in the Empire of Germany.)
On all carding engines there is a greater or lesser space left unoccupied between
the last roller and scraper, because the cover and roller at this point do not press
against the centre of the drum, and therefore cannot be regulated. At this
unoccupied place I attach my new clearing apparatus; this apparatus catches and
takes off knots and husks still remaining in the bottom.
In the accompanying Drawings my apparatus is shewn partly in side elevation
and partly as seen from underneath.
a is a portion of the periphery of the chief drum; b, a portion of the periphery
of the scraper; c, the last roller; d, one of the two cast-iron sides of the apparatus ;
e, wooden rails let into the side pieces d and going across the whole width of the
carding engine to which they are fastened by the steel rails f, which also serve to
support them. These steel rails are really the working portion of my Invention;
they are about 0.5 min. thick, and 3 to 4 m. wide, and well hardened to prevent
their wearing out, and are provided with a single dull edge on the side next the
card. At this place the impurities are scraped off and fall down through the rails
into a catching tin i. The rails are placed at a tangent of 45 degrees to the periphery
of the carding drum; e¹ is a wooden connecting piece partly to fill out the empty
space between the drum and the scraper, and partly to serve as a fastening for the
receiving tin i; are regulating screws to regulate the steel rails. On account of
the different lengths and qualities of cotton, these rails cannot be fixed, but their
proper distance from the card has to be found by trials. By the use of these screws
one or all of the rails can be regulated while the machine is at work with the
greatest ease; m are wood screws screwed into the wooden lining between the
card and the card shields g, and serve as general supports and fixings for the
apparatus; n are bolts fastened into the side shields of the card, and serve to
regulate the whole apparatus with the help of the carriers k; g is one of the side
shields of the card upon which a wooden dust cover is screwed, by means of its
supports, quite across the apparatus.
This apparatus can be used in any old carding machine without any alterations,
as it is only necessary to screw the bolts n into the side screen, and to catch the
apparatus upon them.
My present Invention is not to be mixed up with an apparatus which has some
outward resemblance with it, namely, the three cornered iron bars introduced under
some cards and scraping rollers. These bars do not clean, but only let the dirt fall
through while preventing the cotton from doing so. Without these bars the dirt
would fall through all the same, but a great deal of cotton with it.
My apparatus serves to detach the impurities from the cotton by means of the
steel rails, and to catch the former; without my apparatus the impurities would
stick to the cotton.
Having now particularly described and ascertained the nature of my said
Invention, and the manner of carrying the same into effect, I would have it
understood that what I claim is,―
1. The whole apparatus as described and shewn in the accompanying Drawings,
to be used in connection with a carding engine, in the manner described.

screws b, the side picces d, the connecting piece e¹, the receiving tin i, the bolts n,
and carriers k, for the purpose and in the manner substantially as set forth.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand
and seal, this Twenty-fifth day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
