Sealed the 17th December 1869, and dated the 14th October 1869.
PROVISIONAL SPECIFICATION left by the said Edward Roe at the
Office of the Commissioners of Patents, with his Petition, on the
14th October 1869.
I, EDWARD ROE, of Popham Street, in the Town of Nottingham,
Hosiery Machinist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS AND ADDITIONS IN OR TO MACHINERY OR APPARATUS FOR THE
MANUFACTURE OF LOOPED OR KNITTED FABRICS, AND ALSO OF WARP AND WEFT
FABRICS," to be as follows:-
I take a rotary hosiery machine or any other suitable machine as now
in common use worked with drawing cam and levers, but instead of

page_text: using the drawing cam and levers I propose to use a reversing drum,
which drum is to be worked by means of two bevel wheels, which
wheels are placed in such a manner as to work on a sliding key, and
which key is placed on a parralel shaft, which shaft is placed at the end
of the machine or anywhere convenient. An upright shaft is then
placed at the end of the machine, or anywhere convenient, with a bevel
wheel attached, two to one, to work in gear with the before-mentioned
wheels; and on the same shaft the drum is placed, and the motion of
the drum is given by the bevel wheels before mentioned, which are
worked by a cam so placed as to give motion to the drum, causing it to
revolve half way each motion of the machine, and by sliding one wheel
out and the other wheel in by the before-mentioned cam gives the drum
a reversing motion, which gives motion to a slur cock and carrier thread
layer which is attached to the drum by a chain fixed to a sliding spring
which is fitted into a groove on the drum, so that when it comes to the
stops or narrowing or widening the friction spring stands still whilst the
drum revolves.
The novelty of the Invention consists of a drum which by being
increased or diminished in its diameter enables a much better motion to
be gained than what can be obtained by means of a cam, and producing
a longer and steadier draw than the cam can give, causing much less
breakage in sinkers and needles and threads, and producing a better
fabric, and also fabrics more extensive and in different varieties, as well
as much greater speed than what can be produced by the cam.

the 12th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
ROE, of Popham Street, in the Town of Nottingham, Hosiery Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year

page_text: 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 him, the said Edward Roe, Her special licence that I,
the said Edward Roe, my executors, administrators, and assigns, or
such others as I, the said Edward Roe, 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, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS AND ADDITIONS IN OR TO MACHINERY
OB APPARATUS FOR THE MANUFACTURE OF LOOPED OR KNITTED FABRICS, AND ALSO
OF WARP AND WEPT FABRICS," upon the condition (amongst others) that I,
the said Edward Roe, my executors or administrators, by an 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 Edward Roe, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement :-
I take a rotary hosiery machine or any other suitable machine as now
in common use worked with a drawing cam and levers, but instead of
such cam and levers I propose to use a reversing drum, which drum is
to be worked by means of two bevel wheels, which wheels are placed in
such a manner as to work on a sliding key or to slide on a
key, and
which key is secured to a parallel shaft placed at the end of the machine
or anywhere convenient. An upright shaft is then placed at the end of
the machine or anywhere convenient with a bevel wheel attached, two
to one, to work in gear with the before-mentioned wheels, and on the
same shaft the drum is placed, and the motion of the drum is given by
the bevel wheels before mentioned, which are worked by a cam so placed
as to give motion to the drum, causing it to revolve half way at each
motion of the machine, and by sliding one wheel out and the other
wheel in by the before-mentioned cams gives the drum a reversing
motion, which gives motion to a slur cock and carrier thread layer which

page_text: is attached to the drum by a chain, which chain is fixed to a sliding
spring which is fitted into a groove on the drum, so that when it comes
to the stops or narrowing or widening the friction spring stands still
whilst the drum revolves.
Figure 1 is an end view of one of my improved rotary hosiery
machines with my improved reversing drum and apparatus applied
thereto; Figure 2 is a plan of the same machine and narrowing apparatus,
the standards of the framing being broken off above the slur cock
bar to shew the chains attached to the slur cock sliding bar and the
thread carrier sliding bar driver, such chains being operated by the
drums, the upper one of which is shewn.
The above-mentioned improved rotary hosiery machine is fully
described in the Specification of a Patent granted to me for improve-
ments in the manufacture of looped or knitted fabrics, and in the
machinery or apparatus employed therein, dated the First day of July
One thousand eight hundred and sixty-nine, No. 1991,
Figure 3 is a view of the drums and apparatus from the front of the
machine attached to the right-end standard, but I would have it under-
stood that the said drums and apparatus would work equally as effective
if placed at the left end of the machine. Figure 4 is a sectional view
of the two drums; Figure 5 is a plan of the upper drum V with a
plate V removed, so that a friction spring which I will describe here-
after may be seen; Fig. 6 shews in plan the under side of the plate V' ;
Fig. 7 is one of the wheels which slide on the key on the horizontal
shaft parallel to the end of the machine; Figure 8 is a view of part of
the apparatus at the end of the frame, one of the brackets Y' which
support the bearings of the horizontal shaft being seen endwise, the
cam wheel Z and the upper ends of two levers Z', Z, being seen
sideways.

page_text: The traverse of the thread carrier sliding bar is effected in the following
manner: Attached to the bearings on the central bracket R and right-
hand bracket R is a flat bar S on which a box slides. This box has a
projection in front which carries on its under side a stud, to each side of
which stud a chain or chains 81 are attached, which pass round a
pulley S8, two other pulleys U, and round a drum V, which makes an
alternately reversed partial revolution, such movement of the drum
causing the box and stud to which the chain or chains are attached to
slide alternately to the right or left on the bar S³ until stopped, as
described in my former Patent before referred to. The alternately
reversed partial revolutions of the drums V and W being the same, and
of such an extent as to obtain at each motion of the machine the full
length of traverse required for the slur cock bar X carrying the slur
cocks O, which are traversed to the right or left by means of a chain
passed round the drum W, having its ends attached to the slur cock
bar X, and the length of traverse of the thread carrier sliding bar
varying some provision must be made for such variation. This I effect
in the following manner :-The chain or chains S" are attached to a
piece of metal V³, see Figure 5, which slides in the groove of the
drum V; the sliding piece has a screw V* passed through it, and is
provided with a nut; the inner end of the screw passes into a hole in a
spring V, by which means the pressure of the spring on the drum can
be adjusted. Such sliding piece, screw, and spring are shewn without the
chains attached at Figure 3; a portion of the top flange of the drum V
is cut away to allow of the insertion of the spring and sliding piece, the
space so formed being filled by a plate V, which is attached to the top
flange of the drum V by screws. By this arrangement the drum
traverses the thread carrier sliding bar the distance determined by the
stops in narrowing or widening, and continues its partial revolution
either way until it stops previous to being reversed, During such con-
tinued partial revolutions the friction spring stands still.
The reversed movement of the drums I affect by the following means:
-Upon one end of the main cam shaft O' is secured a bevel wheel Y
which gears into a like wheel Y' on a short horizontal shaft lying in
bearings Y parallel to the end of the machine; this shaft is provided
with a key upon which slides two other bevel wheels Y, Y³; these
wheels have only nine teeth cach, as shewn at Figures 3 and 7, and

page_text: are moved in or out of gear with a full toothed bevel wheel Y* secured
on the lower end of a vertical shaft, which is held in bearings secured to
the end standards of the machine, and carries at its upper end the
drum V, W, before mentioned; the wheels Y', Y', have each a grooved
collar in which a fork is placed, one of which forks is secured to a
bar Z and the other to a bar Z*; these bars slide in bearings secured
to brackets Y; the bars Z and Z' are moved to and fro alternately by
the upper ends of two levers Z, Z, which are free to move at their
lower ends on an axle pin which is secured in the end standard of the
machine, the upper ends of the levers being actuated by one or other
of the cams which project from each side of a toothed cam wheel Z,
which is caused to revolve by a smaller toothed wheel secured on the
main cam shaft O' between the standard of the machine and the bevel
wheel Y. The upper end of the lever Zas it is in its turn moved
outwards by the cam wheel strikes upon an adjustable set screw in an
arm Z³ secured on the sliding bar Z³, and places the teeth of the bevel
wheel Y in gear with the bevel wheel Y' on the lower end of the
drum shaft which is moved part of a revolution, the wheel Y* dis-
engaging itself as it revolves, and is brought clear of the wheel Y* by
a spring on the bar Z'. The lever Z then in its turn is acted on in
like manner, and throws the teeth of the bevel wheel Y' in gear with
the wheel Y. The lever Z' striking upon an adjustable set screw in an
arm Z* secured on the sliding bar Z places the teeth of the bevel wheel Y³
in gear with the wheel Y*, causing a partial revolution of the drum the
reverse of the previous one.
The machinery and apparatus I have described relate to hosiery or
other machines wherein two separate varying traverses of bars or threads
are required; but in lace machines, warp, or other machines in which a
bar or bars, or thread or threads are required to be traversed an extra
or unusual length the same apparatus will be equally effective if the
number of drums be increased, and the drum shaft be driven at a greater
speed during each motion of the machine, or during part of the time
the said machine is making one complete series of movements, or the
diameter of the drum or drums may be increased to produce the same
effect.
Having thus described the nature of the said Invention, and in
what manner the same is to be performed. I declare that what I claim

page_text: is, the arrangement and combination of parts of machinery to produce
two or more separate reversed traverses or varying reversed traverses
of a thread or threads or part or parts of machinery, as herein-before
described.
In witness whereof, I, the said Edward Roe, have hereunto set
my hand and seal, this Fifth day of April, in the year of our
Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered by
the said Edward Roe in the
presence of
