Improvements in Feeding and Burring Mechanism for Carding
Machines.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to improvements in feed mechanism for carding machines
and is illustrated in the accompanying drawing in which
Fig. 1 of the drawings is a central vertical cross-section of the feed-chute and
rolls, and a part of the main carding cylinder.
Fig. 2 is a similar view showing a modified arrangement and form of rolls.
A is a vertical chute or fixed box, open at the top and bottom and provided at or
near the botton with a pair of feed-regulators A¹, and A. 2.
The regulators each consist of a roller A 3 rotary in suitable bearings, not shown,
and provided with the. radial arms or blades A 4, to guide the stock..
The regulators are located on opposite sides of the chute and rotate in the direction
of the arrows shown in Fig. 1, to regulate the downward flow of the stock, which
may be wool, cotton or the like, engagable by the blades A 4.'
Subjacent to the regulators are the two feed rolls B, and B¹, also rotary in suit-
able bearings and provided with rearwardly inclined teeth B 2 which engage the
stock as they rotate in the direction indicated by the arrows, and feed it down
to the burr-cylinder B 3 which acts upon the stock in conjunction with the worker-.
rolls B 4 in the 'usual well known manner, the direction of rotation being indicated
by arrows.
The burr-cylinder B5, strippers B6 and toothed cylinder B7 serve to carry
the stock from the large burr-cylinder B3 to the main cylinder B8 of a carding
machine, or to a weighing-pan B 9. The rollers B3, B4, B and B are provided
with the usual well known teeth appropriate to such rollers in this class of
machines.
The carding and weighing mechanisms being old and well known, are not fully
shown.
The feed-rolls rotate faster than the feed-regulators; the workers faster than
the feed-rolls; the burr-cylinder B 3 faster than the workers; the burr-cylinder or
wheel B 5 has a still greater peripheral speed, but not equal to that of the main
cylinder of the carding machine.
The draft is equal upon opposite sides of the stock until it reaches the burr
cylinder B Where the drafting apparatus engages one side only of the stock it
tends to roll the stock or ball it. By engaging the stock on opposite sides, equally
rolling is prevented and the fibres are drawn out and arranged in straight parallel
lines.
I am able to regulate the supply of stock fed by regulating the speed of the
feed-regulators, or by increasing or diminishing the proximity to each other of the
feed-rolls. as well as their speed.

page_text: By means of the burr-cylinders and strippers, I am also able to remove burrs
and other foreign substances before the stock reaches the carding machine,
proper.
The stock may be deposited in the chute in any known manner; and the chute
may be of any desired length or shape.
In the operation of the apparatus, the burr-cylinder B3 is the first drafting
wheel which draws directly from the middle of the mass of material in the lower
end of the chute. This draft is partly resisted by the relatively slow regu-
lators A 3 directly in the outlet of the chute. The draft of the cylinder B 3 is
still further resisted by the resisting toothed rolls B, B', interposed between the
regulators and drafting roll. It is obvious that the number of pairs of resisting
rolls, or of drafting rolls may be increased to any desired limit without affecting the
scope of my invention.
Figure 2 shows two pairs of resisting rolls interposed between the regulators A¹,
and the burr-cylinders B³, and a weighing pan instead of the carding cylinder.
The dotted circles in such figure indicate positions which may be occupied by various
workers and other rolls as desired.
Any known means may be employed for imparting rotary movements to the
cylinders and rolls.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:
1. In a feeding mechanism for carding machines, the combination with a
gravity-feed chute, of a toothed drafting roll, and one or more pairs of co-operating
resisting-rolls interposed between the drafting roll and the chute outlet, the
individual rolls of each pair being located on opposite sides of such outlet,
substantially as described.
2. In a feeding mechanism for carding machines, the combination with a
gravity-feed chute, a pair of rotary feed-regulators oppositely disposed at the
outlet of the chute, and a pair of subjacent, toothed resisting-rolls, of a toothed
drafting roll co-operative with the resisting and regulating rolls, rotary movements
being imparted to the regulators and rolls, the speed of the rotary movements
being greatest in the rolls farthest removed from the chute, substantially as
described.
3. In a feeding mechanism for carding machines, the combination with a
gravity-feed chute, and a series of drafting rolls, of a pair of feed-regulators
co-operating with the drafting rolls and rotary in the outlet of the chute, one on
one side of the chute and the other on the opposite side, substantially as
described.
