Fibrous Materials.
We WILLIAM HALL RICHARDSON of Bank View, Derker, Oldham in the County of
Lancaster, Machinist and THOMAS RODGERSON MARSDEN of 94 Greengate Street,
Oldham, aforesaid Foreman, both in the employ of Messieurs Platt Brothers and Com-
pany, Limited of Oldham aforesaid, Machinists, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to those machines used for preparing cotton and other fibrous
materials to which the cotton or other fibrous material to be operated upon is supplied
by means of a feed-roller in conjunction with which feed-roller are employed weighted
levers from which are suspended pendent rods the lower end of each of which is
formed inclined or wedge-shaped and which pendent rods acting by means of bowls
or rollers and rods and levers regulate the speed of the feed-roller by altering the
position of the strap upon the cones by means of which motion is imparted to the
feed-roller and thus cause the speed of the feed-roller to be regulated by the thickness
of the supply of cotton or other fibrous material supplied to such feed-roller.
Our invention consists in arrangements by means of which we are enabled to form
a "lap" more uniform in weight and thickness than the "laps" formed in machines
as hitherto constructed. Our invention also enables the feed-regulating apparatus to
be more readily inspected, cleaned and adjusted than the feed-regulating apparatus
hitherto constructed.
To one end of the box or frame which acts as a guide to the lower ends of the
pendent rods before-mentioned we secure a bracket provided with a stud mounted
upon which and capable of being oscillated thereon is a lever one arm of which is
formed with a slot. To the said lever is jointed one end of a rod the other end of
which is jointed to one arm of a bell-crank-lever mounted upon a stud secured to a
bracket upon the box or frame above-mentioned. The remaining arm of the bell-
crank-lever above-mentioned is connected to one end of a chain which passes over a
pulley mounted upon an axle capable of being turned freely in suitable bearings. The
Din 77

page_text: remaining end of the said chain is connected by means of links to the levers carrying
the strap-guides by which the said strap is moved upon the cones in order that the
speed of the feed-roller may be governed, controlled or regulated.
As any one or more of the pendent rods above-mentioned is or are raised or lowered
as the thickness of the cotton or other fibrous material supplied to the feed-roller
varies such pendent rod or rods will by means of its or their wedge-shaped or inclined
end or ends and the bowls or rollers ordinarily employed in conjunction therewith act
upon the lever, rod, bell-crank-lever and chain above referred to so as to move the
levers carrying the strap-guides and move the strap before referred to upon the cones
and vary the speed of the feed-roller.
The lever above-mentioned to which the rod above referred to is jointed may by
means of the slot aforesaid be adjusted to give the desired amount of motion to the
levers carrying the strap-guides. We adjust the rod above-mentioned to the length
desired by means of a bracket screwed upon a screwed part of the said rod or by any
other convenient means. We provide the axle of the pulley above-mentioned with a
finger or pointer which acting in conjunction with a dial indicates the position of the
strap upon the cones.

:
Improvements in Machines for "Preparing" Cotton and other
Fibrous Materials.
We WILLIAM HALL RICHARDSON of Bank View Derker Oldham in the County of
Lancaster Machinist and THOMAS RODGERSON MARSDEN of 94 Greengate Street
Oldham aforesaid Foreman both in the employ of Messieurs Platt Brothers and Com-
pany Limited of Oldham aforesaid Machinists do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Our invention relates to those machines used for "preparing" cotton and other
fibrous materials to which the cotton or other fibrous material to be operated upon is
supplied by means of a feed roller in conjunction with which feed roller are employed
weighted levers from which are suspended pendent rods the lower end of each of

page_text: which is formed inclined or wedge-shaped and which pendent rods acting by means of
bowls or rollers and rods and levers regulate the speed of the feed-roller by altering
the position of the strap upon the cones by means of which motion is imparted to the
feed-roller and thus cause the speed of the feed-roller to be regulated by the thickness
of the supply of cotton or other fibrous material supplied to such feed-roller.
Our invention consists in arrangements by means of which we are enabled to form
a "lap" more uniform in weight and thickness than the "laps" formed in machines
as hitherto constructed. Our invention also enables the feed-regulating apparatus to
be more readily inspected, cleaned and adjusted than the feed-regulating apparatus
hitherto constructed.
To one end of the box or frame which acts as a guide to the lower ends of the
pendent rods before mentioned we secure a bracket provided with a stud mounted
upon which and capable of being oscillated thereon is a lever one arm of which is
formed with a slot. To the said lever is jointed one end of a rod the other end of
which is jointed to one arm of a bell-crank-lever mounted upon a stud secured to a
bracket upon the box or frame above mentioned.
The remaining arm of the bell-crank-lever above mentioned is connected to one end
of a chain which passes over a pulley mounted upon an axle capable of being turned
freely in suitable bearings. The remaining end of the said chain is connected by
means of links to the levers carrying the strap-guides by which the strap is moved
upon the cones in order that the speed of the feed-roller may be governed controlled
or regulated.
As any one or more of the pendent rods above mentioned is or are raised or lowered
as the thickness of the cotton or other fibrous material supplied to the feed-roller
varies such pendent rod or rods will by means of its or their wedge-shaped or inclined
end or ends and the bowls or rollers ordinarily employed in conjunction therewith act
upon the lever, rod, bell-crank-lever and chain above referred to so as to move the
levers carrying the strap-guides and move the strap before referred to upon the cones
and vary the speed of the feed-roller.
The lever above mentioned to which the rod above referred to is jointed may by
means of the slot aforesaid be adjusted to give the desired amount of motion to the
levers carrying the strap-guides. We adjust the rod above mentioned to the length
desired by means of a bracket screwed upon a screwed part of the said rod or by any
other convenient means. We provide the axle of the pulley above mentioned with
a finger or pointer which acting in conjunction with a dial indicates the position of the
strap upon the cones.
Figs. 1 and 2 of the accompanying drawings show a method of carrying our in-
vention into effect. Fig. 1. is a side view and Fig. 2. an end view showing so much
of a machine for "preparing" cotton or other fibrous materials as is necessary to show
the mode of applying our invention. a. is the-feed-roller in conjunction with which
feed-roller a. are employed weighted levers b. The levers b. are supported upon a
rod or bar c. One end of each of the levers b. passes beneath the feed-roller a.
From the remaining ends 62 of the levers b. are suspended pendent rods d. The
lower ends.d' of the pendent rods d. are formed wedge-shaped or inclined. Secured
to the side frames e. of the "preparing machine" are brackets f. to which is secured a
box or frame g. through which the lower ends d' of the pendent rods d. pass the box
or frame g, acting as a guide to the pendent rods d. To the box or frame y. we secure
a bracket . provided with a stud j. mnounted upon which and capable of being oscillated
thercon is a lever k. provided at one end with a slot k¹. To the lever k. is jointed by
a stud ² one end of a rod 1. the other end of which is jointed by means of a stud m¹
to one arm of a bell-crank-lever m. mounted so as to be capable of being oscillated
upon a stud n¹ secured to a bracket n. secured to the box or frame g. To the
remaining arm of the bell-crank-lever m. is connected one end of a chain o. which
chain o. passes over a pulley p. mounted upon an axle q. capable of being turned in
bearings formed in a bracket or box r. The remaining end of the chain o. is con-
nected by means of links s. to the levers t, t which levers t..t¹ respectively carry
strap-guides u, by which the strap v. is moved upon the cones to, w¹ in order that

page_text: the speed of the feed-roller a. may be governed, controlled or regulated. As any one
or more of the pendent rods d. is or are raised or lowered as the thickness of the
cotton or other fibrous material supplied to the feed-roller a. varies such pendent rod
or rods will by means of its or their wedge-shaped or inclined end or ends and the bowls
or rollers a. ordinarily employed in conjunction therewith act upon the lower end of a
part 3 connected to the lever k. rod 1. bell-crank-lever m. and chain o. so as to move
the levers t, t¹ and move the strap . upon the cones w. w¹ and vary the speed of the
feed-roller a.
By securing the stud 2 in the slot at a position nearer to or farther from the
stud j. upon which is mounted the lever k. the desired amount of motion may be given
to the levers t. t carrying the strap-guides u. u¹.. In order to adjust the rod 7. to the
length desired we form the rod 1. of two portions and 12. Upon the portion of
the rod 1. we secure a socket or bracket y. which screws upon screw-threads z. formed
upon the portion 12 of the rod l. After the rod 1. has been adjusted to the desired
length we secure the socket or bracket y. upon the rod 1. by means of the wing-
nut y¹.
We provide the axle q. with a finger or pointer which acting in conjunction with
a dial q indicates the position of the strap . upon the cones w. w.
Instead of the pendent rods d. and bowls or rollers a. being caused to act upon the
lever . by means of a part k³ as shown in Fig. 2. of the drawings hereunto annexed
such pendent rods d. and bowls or rollers a. may be caused to act upon the lever k.
by means of any other suitable appliances or in any other suitable manner.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is :-
In machines for "preparing" cotton and other fibrous materials the combination
with the pendent rods d. and bowls or rollers a. of the bracket 7. leverk slot k¹ rod l.
socket or bracket y. provided with screw-threads and wing-nut y¹. bracket n. bell-crank-
lever m. chain o. pulley p. and links s. all constructed arranged and operating for the
purposes and substantially in the manner hereinbefore described in reference to and
indicated by the drawings hereunto annexed.
