Improvements in Carding Machines.
I, JOHN CHEYNE, of Paterson, in the County of Passaic, State of New Jersey,
United States of America, Superintendent, do hereby declare the nature of my
invention for IMPROVEMENT IN CARDING MACHINES, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to carding machines, and has for its object to straighten out
and partly draw the carded jute or other fiber in the carding machine preparatory to
transferring the same to the drawing machine.
The invention consists in devices illustrated in the accompanying drawing which
will be hereinafter fully described and pointed out in the claims.
Figure 1 of the drawing is a side elevation of a portion of an ordinary carding
machine, with my invention attached.
Figures 2 and 3 show opposite ends of my invention detached.
Figure 4 is a front view of the same, in which figure the shaft is represented as
broken.
A represents a portion of an ordinary carding machine having the usual supporting
frame A¹, cross-bar A³, shaft. a, rollers e, e', cylinder f, gears g, g', g³, g³, g', b, b₁, and c.
The machine, which is constructed as usual, need not be further described herein.
In bearings suitably arranged in the machine frame rollers B and C are journaled.
In the periphery of the roller B I arrange pins or teeth B', which teeth or pins are
adapted to pass through between the fibers of carded jute or other fiber and straighten
out the same longitudinally preparatory to the fibers passing to the roller C and
between the said roller and roller D, which last mentioned rollers, owing to the
quickness of their speed, are adapted to partly draw the carded and straightened fibers
preparatory to their transfer to the drawing machine.
The roller D is arranged in bearings D₁, formed in an upwardly projecting part of
the frame A', and receives its motion from the roller by its contact therewith, but
is held in contact more or less yielding with the roller C to accomodate the fiber n by

page_text: rods D², spring D³, and screw D₁, which connect with cap bearing D' and cross
bar D, as shown.
The jute or other fiber passes from between the rollers C and D to an idler roller E,
and between the idler E and drawing roller C. The idler E is arranged in slots E¹,
which are formed in projecting portions of the machine frame, and in said slots the
roller E, is adapted to accomodate itself to the wants of the fiber n.
The roller Cis provided with gears e² and d, the former of which gears with and is
actuated by an intermediate gear c', which latter gears with and is turned by a gear e
fixed on the shaft a, which shaft and roller e¹ thereon is turned by a gear g' which
gears with and is rotated by a gear that meshes with and is actuated by a gear g²,
which latter gears with a like gear g¹ which receives its motion from a pinion g fixed
on the cylinder f as shown.
The roller e receives its motion from a pinion 6 on the shaft a that gears with a
gear on the said roller e. The toothed roller B is turned by an intermediate gear
wheel d¹ that meshes with and is turned by a pinion d on roller C, while the intermediate
gears with and imparts motion to gear d² on roller B.
The intermediate pinion c¹, from which the roller C receives its motion, is arranged
on a stud r, fixed in a bar C2, which bar at its upper end is arranged on the shaft a
and which has a slotted lower end, that is secured in the slot C³ thereof to the frame A¹
by a bolt C, and which can be adjusted to suit a larger or smaller gear C¹ to regulate
the speed of the roller C.
The machine is supposed to be in motion.
The carded fiber n is delivered to the roller B by rollers-e, e'. The fibor, while the
same is passing over the roller B to the drawing rollers C and D, is manipulated and
straightened by the action of the pins or teeth B¹. The carded and straightened fiber
then passes between the rollers C and D, and is partly drawn by the last mentioned
rollers and passes between the idler E and roller C preparatory to its transfer to the
drawing machine.
The toothed roller B and drawing roller C may be speeded up indefinately to
accomplish the straightening and drawing of the fiber, by reason of which the carding
machine can be run at a higher speed to increase the production of the same, while
the drawing machine to which the straightened and partly drawn fiber is taken from
the machine A can complete the drawing of the jute or other fiber at a quickened.
speed with less strain on the parts by reason of my invention.
Thus it will be seen that a given quantity of jute or other fiber can be carded and
drawn with a less number of carding and drawing machines by reason of my invention;
while the spun yarn made from a cheaper material will by reason of the same command
higher price in the market than yarn made from the best materials without the use
of my invention.
a
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
In a carding machine, the combination with rollers e e¹, and gears thereon, of the
roller B and gears thereon, gear d', the roller C and gear on said roller, the roller D,
roller E, the rods D2, spring D³ the screw D', gear O¹, the bar C² having slot C³,
bolt C, the gears g' g³, gears g³ gl, and pinion g, all arranged and operating substantially
as described.
