Machine Maker, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY FOR PREPARING. SPINNING, AND DOUBLING COTTON AND
FIBROUS SUBSTANCES."
Scaled the 12th February 1864, and dated the 15th August 1863.
PROVISIONAL SPECIFICATION left by the said Edward Lord at the
Office of the Commissioners of Patents, with his Petition, on the 15th
August 1868.
I, EDWARD LORD, of Todmorden, in the County of York, Machine Maker,
do hereby declare the nature of the saii Invention for CERTAIN IMPROVE-
MENTS IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON, AND
OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention is applicable to all machines employed in preparing, spinning,
and doubling fibrous substances in which drawing or holding rollers are used,
and it consists in holding the fibres or yarn to be operated upon between a
roller and a weighted trough or plate, either whole or divided into sections
similar to those employed by me for feeding blowers and other machines, and
described in the Specification of Itters l'atent granted to me on the Twenty-
eighth day of December One thousand eight hundred and sixty-one, No.3219.
The surface of the roller Letween which and the trough or plate the fibres or
yurus pass is fluted or furnished with teeth, or otherwise roughened or covered

while they are drawn forward by a pair of drawing rollers of the usual
construction, or by a roller and trough, as above described, or otherwise.
SPECIFICATION in pursuance of the conditions of the Letters Patout, filed
by the said Edward Lord in the Great Seal Patent Office on the
13th February 186-4.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LORD, of Todmorden, in the County of York, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of August, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself. Her heirs and successors, give and grant
unto me, the said Edward Lord, Her special license that I, the said Edward
lord, my executors, administrators, and assigns, or such others as I, the
said Edward Lord, 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
"CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING
COTTON AND OTHER FIBROUS SUBSTANCES," upon the condition (amongst others)
that I, the said Edward Lord, my executors or administrators, by an instru-
ment 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 tho said Letters Patent.
NOW KNOW YE, that I, the said Edward Lord, 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 (that is to say):-
My Invention isapplicable to all machines employed in preparing, spinning,
and doubling fibrous substances in which drawing or holding rollers are used,
and it consists in holding the fibres or yarn to be operated upon between a
roller and a weighted trough or plate, either whole or divided into sections
similar to those employed by me for feeding blowers and other machines, and

page_text: described in the Specification of Letters Patent granted to me on the Twenty-
eighth day of December One thousand eight hundred and sixty-one, Number
3219. The surface of the roller between which and the trough or plate the
fibres or yarns pass, is fluted or furnished with teeth, or otherwise roughened
or covered with leather or other suitable material, to keep hold of the fibres
or yarns while they are drawn forward by a pair of drawing rollers of the
usual construction, or by a roller and trough,as above described, or otherwise.
And in order that my Invention may be fully understood, I will procced
to describe the accompanying Sheet of Drawings.
Figure 1 is a section through the drawing head of a carding engine con-
structed according to my improvements. a represents the spout through
which the fleece of fibres is conveyed to the weighted trough b; this trough
rests upon the fulcrum c, and it may be either in one piece, or divided in
sections,similar to those employed for feeding blowers and other machines, as
described in the Specification of Letters Patent granted to me on the Twenty-
eighth day of December One thousand eight hundred and sixty-one, Number
3219. Above the trough is the roller d,the surface ofwhich is made rough,
by turning annular grooves at right angles to the usual flutes, or in any other
convenient manner, or it may be covered with leather, or other suitable
material. The sliver is drawn forward from the spout a by the roller 1, and it
is delivered over the edge of the trough 6 to the drawing rollers e and f, which
revolve at a greater velocity than the roller d, between which and the lip of
the trough the fibres are securely held until drawn forward by the said
drawing rollers. The top roller e is or may be fluted like the bottom roller f.
The fulcrum c is adjustable by making a slot in the bracket, through which
the screw passes for attaching it to the under side of the plate over which tho
fleece from the doffer is taken to the spout , or in any other convenient
manner. The bearings of the rollers cand fare also adjustable,for regulating
the distance between the nip of the rollers and the lip of the trough b,accord-
ing to the length of the staple of the fibres operated upon.
Figure 3 is an elevation of part of a drawing frame constructed according
to my Invention. The slivers are guided by the studs a to the trough b,
vibrating on the fulcrum c; below the weighted end of the trough is a pro-
jection, through which passes a set screw y; the head of this set screw rests
against the side of the fulcrum c, and by turning the screw round, either in
one direction or the other, the lip of the trough b can be adjusted so as to
tighten the fibres more or less against the roller d. The drawing rollers e
and are made as usual.
Figuro represents part of a roving frame constructed according to my

page_text: improvements; in this case the heavier end of the trough a is recessed, to
form a guide for the slubbing, which is carried forward between the concave
part of the trough and the roller d, from which it is drawn by the rolle rse, 1,
as before described. The troughs bare supported or the fulcrum shaft c, to
which are fixed by set screws the fingers h; the pressure of the trough against
the roller is regulated by the position of these fingers.
Figure 5 represents a modification of my Invention; in this case i is a
bracket bolted to the roller, beam, or other fixture; to the bracket i are fixed
the bearings and k, the former supporting the fulcrum c of the uppor
trough band the roller d, and the latter the fulcrum c' of the trough band
the roller d. The sliver,slubbing, or roving to be drawn or clongated passes
through a recess in the trough & to the roller d, then to the roller d¹ and
trough ; the distance between the nips of the rollers d,d, and troughs b, b',
can be regulated by the slots in the brackets and in the bearings j and .
The pressure between the troughs b, 4, and the rollers d, e, is given by the
india-rubber or other springs 1, P, and it is regulated by the set screws g, g².
Figure 6 represents my improvements as applied to a machine for spinning
or doubling; the rail a las holes to guide the roving or yarn between the
trough and roller d, from whence it is drawn by the rollers e and f, as
before described. The fulcrum bar cand the regulating fingers
similar to those shewn in Figure 4.
are
Laving thus stated the nature of my Invention, and described several
modes of carrying the same into operation, I wish it to be understood that I
do not intend to limit myself to the details given, as they may be considerably
modified without departing from the peculiar character of the Invention. 1
would also observe that I do not claim the application of a concave trough
to a feed or holding roller; but what I do claim is, the application of a
weighted trough to a holding roller, as shewn and described, and the means
whereby the pressure between the two is regulated.
In witness whereof, I, the said Edward Lord, have hereunto set my
hand and seal, this Twelfth day of February One thousand eight
hundred and sixty-four.
