at the Office of the Commissioners of Patents, with his Petition,
on the 28th October 1869.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN DRAWING FRAMES," to
be as follows:-
This Invention relates to improvements in drawing frames for dressing
Manilla and all other hemp and similar substances, and consists in

as commonly used for dressing the laps and reducing them to slivers)
of a series of revolving combs working on an endless carrying apron.
The hemp is dressed and delivered in laps or bats to the endless chain,
so as to serve as a substitute for the lap machines now used for dressing
the hemp previous to its being fed to the endless chain. The chain is
arranged to move at a greater surface speed than the revolving combs,
whereby it draws the hemp through the teeth of the revolving combs,
and its own teeth are caused to move faster than the hemp, and a
thorough and efficient combing action is produced on the same. All
these operations are accomplished in one complete machine more
economically than heretofore, requiring only one feeding operation and
less attendance.

resistance, whereby as the chains are at present arranged the combs are
tilted backward so as to allow the fibre to slip off.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal Patent
Office on the 28th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of October, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Newton, Her special
licence that I, the said William Edward Newton, my executors, adminis-
trators, and assigns, or such others as I, the said William Edward
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,

page_text: use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN DRAWING FRAMES," being a communication to me from
abroad by Charles Wall, of the City and State of New York, United
States of America, upon the condition (amongst others) that I, the
said William Edward Newton, my executors or administrators, by au
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thercon (that is
to say):
-
This Invention relates to improvements in drawing frames for dressing
Manilla and other hemp and similar substances, and consists in com-
bining with the endless chain combs and condensing apparatus (such
as are commonly used for dressing the laps and reducing them to slivers)
of a series of revolving combs working on an endless carrying apron.
The hemp is dressed and delivered in laps or bats to the endless chain,
so as to serve as a substitute for the lap machines now used for dressing
the hemp previous to its being fed to the endless chain. The chain is
arranged to move at a greater surface speed than the revolving combs,
whereby it draws the hemp through the teeth of the revolving combs,
and its own teeth are caused to move faster than the hemp, and a
thorough and efficient combing action is produced on the same. The
operations are accomplished in one complete machine more econo-
mically than heretofore, and require only one feeding operation and less
attendance.
The Invention also comprises a guard attachment for the endless chain
for the better control of the chain when the substance under treatment
offers great resistance, whereby as the chains are at present arranged
he combs are tilted backward so as to allow the fibre to slip off.

page_text: In the accompanying Drawing Fig. 1 is a side elevation of the
improved machine with some parts shewn in section; Fig. 2 is a plan
view of the same; and Fig. 3 is a transverse section taken in the
line x, x, of Fig. 2.
A represents the endless chain of the drawing frames, and A¹ the
condensing apparatus to which the laps are now presented to be dressed
and reduced to slivers. These parts are of the common construction
and arrangement except as to the guiding angle plates B, which are
attached to the rails C of the frame, and are arranged so that the
vertical parts D project downward to the top of the chain rods E to
prevent more effectually the raising of the rods and tilting backward
which takes place when the hemp offers great resistance, and which is
not prevented as much as is desirable by the stud pin F applied to the
plates G at the ends of the rods for the purpose. These pins work under
and above the ribs H on the side rails of the frame. The frame of this
machine is extended at the receiving end, and there is an endless
carrying belt K. and a series of revolving comb cylinders L above it, also
a feeding belt M and feeding rollers N, and under each comb cylinder
is arranged a smooth roller N¹ for keeping the belt up to the comb
cylinders. All the comb cylinders and rollers are geared together in
any suitable way to impart a uniform speed, and to cause them to move
in the direction to convey the fibre towards the endless chain A, but at
a slower speed than that of the chain. In this example is represented
the roller and comb cylinders as being driven by a belt O working upon
a pulley P connected with the driving mechanism for the chain A, but
they may be operated in any other suitable way. To this drawing and
combing apparatus the hemp is supplied over the feeding apron M in
the same condition that it is now fed to the lap machines, and it is
reduced to slivers as above described in an efficient and economical
manner. Any number of the comb cylinders preferred or found best in
practice may be used.
Having now described the Invention which has been communicated
to me as aforesaid I claim as the Invention secured to me by Letters
Patent,―
First. The combination with a drawing frame of a combing and
drawing apparatus consisting of revolving comb cylinders L, endless
carrying belt K, and rollers N, and feeding devices, as herein set forth.

page_text: Second. The combination with the comb rods E of the endless chain A
and the angle guide plates B, as specified.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the 27th day of April, in the
year of our Lord One thousand eight hundred and seventy.
