pursuant to the Statutes in that case made and provided.
WHEREAS since filing the Specification to the said Letters Patent for improve-
ments in the treatment of stable manure and in the manufacture of paper, I have
been advised that the claiming clauses at the end of the said Specification arc too
wide, and do not define with sufficient precision the limit to which I desire to
confine my Invention :
by
I therefore, for these reasons, desire to disclaim and alter my said Specification,
and I do hereby disclaim and alter the same by substituting in page 2, line 40, of
the Specification, as it is printed by Her Majesty's Printers, for the words "by any
" means " the words “as above described," and, inserting in page 3, line 1, after
the word " manure the words "that is to say, separating the manure in a shaking
"machine, such as is herein-before described, and treating the moist straw in a
drying chamber, such as is herein-before described, and also employing the straw
so treated," and by omitting in page 3, line 2, the word "and."

And in order that the effect of this Disclaimer and Memorandum of Alteration
may be better understood I annex a copy of the Specification as it will appear when
such Disclaimer and Memorandum of Alteration is made as aforesaid.

axes. The axes are cranked where they are embraced by the journals of the
"boxes or frames, and have (if four boxes be used) four crank throws at 90 degrees
apart; a 2 inch throw is suitable. One of the axes is driven in any convenient
manner, and the other axis revolves at the same speed in consequence of the boxes
or frames conveying the movement from the cranks on one axis to those on the
"other. The cranks to which the outer boxes on either side are attached are
diametrically opposite to each other, and so also are the cranks to which the two
"intermediate boxes are attached. The stable manure is fed on to the surface of
"the boxes or frames at one end, and by their motion is carried forward to the
opposite end, where the straw is delivered, the manure having been shaken out
"from it during the transit. By this means the manure is thoroughly shaken out

Portland Place, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN THE TREATMENT OF STABLE MANURE AND IN THE MANUFACTURE OF
PAPER"
Sealed the 16th September 1876, and dated the 6th July 1876.
PROVISIONAL SPECIFICATION left by the said William Frederick Nast at

WILLIAM FREDERICK NAST, of the City of New York, in the United States of
America, Stock Broker, now residing at the Langham Hotel, Portland Place, in the
County of Middlesex. "IMPROVEMENTS IN THE TREATMENT OF STABLE MANURE
AND IN THE MANUFACTURE OF PAPER."
This Invention has for its object improvements in the treatment of stable
manure and in the manufacture of paper.
For these purposes stable manure is subjected to the action of a shaking
machine. By this means the manure is thoroughly shaken out, and separated from
the straw.
The moist straw, free from manure, is next placed in a drying chamber, through
which a current of air of any temperature is drawn or propelled.
The straw is carried forward through the chamber by endless chains or other-
wise, and also it is exposed as thoroughly as possible to the air by means of
mechanical or other agitators; or the straw is first passed through water, and then
dried by any means, and the ammonia is subsequently recovered from both the
water and air by the most economical or other means. When discharged from the
drying chamber the straw is dry.

chamber, is then recovered. This ammonia in any form is either reconducted

nuisance is avoided.
The dried straw is fit to be used for making paper, and for any purposes for
which straw is ordinarily used. The small quantity of ammonia which the
straw retains tends to toughen and improve the quality of the paper.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Frederick Nast in the Great Seal Patent Office on the 6th
January 1877.
WILLIAM FREDERICK NAST, of the City of New York, in the United States of
America, Stock Broker, now residing at the Langham Hotel, Portland Place, in the
County of Middlesex. "IMPROVEMENTS IN THE TREATMENT OF STABLE MANURE
AND IN THE MANUFACTURE OF PAPER."
This Invention has for its object improvements in the treatment of stable manure
and in the manufacture of paper.
For these purposes stable manure is subjected to the action of a shaking
machine. The shaking machine which I employ consists of four or other number
of open boxes or rectangular ladder-like frames of wood about 12 feet long or
longer, and, say, ten inches wide; they are placed side by side, and the cross bars
stand somewhat above the level of the side bars. Near their ends the boxes or
frames are connected to suitable journals with two parallel axes.
The axes are
cranked where they are embraced by the journals of the boxes or frames, and have
(if four boxes be used) four crank throws at 90 degrees apart; a 2 inch throw is
suitable. One of the axes is driven in any convenient manner, and the other axis
revolves at the same speed in consequence of the boxes or frames conveying the
movement from the cranks on one axis to those on the other. The cranks to which
the outer boxes on either side are attached are diametrically opposite to each other,
and so also are the cranks to which the two intermediate boxes are attached.
The stable manure is fed on to the surface of the boxes or frames at one end, and
by their motion is carried forward to the opposite end, where the straw is delivered,
the manure having been shaken out from it during the transit. By this means the
manure is thoroughly shaken out, and separated from the straw.
The moist straw, free from manure, is next placed in a drying chamber, through
which a current of air of any temperature is drawn or propelled.
The straw is carried forward through the chamber by endless chains or other-
wise, and also it is exposed as thoroughly as possible to the air by means of
mechanical or other agitators; or the straw is first passed through water, and then
dried by any means. When discharged from the drying chamber the straw
is dry.
The dried straw is fit to be used for making paper, and for any purposes for
which straw is ordinarily used. The small quantity of ammonia which the straw
retains tends to strengthen and improve the quality of the paper.
The process for the manufacture of paper is similar to that now in use for the
manufacture of paper from straw, and such like materials, but less alkali will be
required in consequence of the straw being already prepared by the action upon it
of the ammoniacal constituents of the manure.
Having thus described the nature of my said Invention, and the manner of per-
forming the same, I would have it understood that I do not confine myself to

page_text: the exact details; but I claim, my improvements in the treatment of stable manure
and in the manufacture of paper, substantially as herein descried.
In witness whereof, I, the said William Frederick Nast, have hereunto set
my hand and seal, this Fifth day of January, in the year of our Lord One
thousand eight hundred and seventy-seven.
