PROVISIONAL SPECIFICATION.
An Improvement in Carding Engines.
I CHARLES THORNES PHILLIPS of Ossett in the County of York, Woollen
Manufacturer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to avoid the waste or loss due to the fine woollen
fibres being thrown down from the swift immediately after passing the doffer along
with the coarser burr or waste.
For this purpose I place a roller of wood or metal immediately beneath the line
of contact or meeting of the swift and doffer, but closer to the swift. This roller
is placed so close to the swift that any light wool fibre, which may be thrown off
from the swift as it passes the doffer, is immediately caught on the surface of the
roller and brought back close to the teeth of the swift, so as to be caught by the
latter and again carried round with the swift.
The roller may be of wood or metal, and plain or with longitudinal corrugations.
In the latter case the depressions of the roller will receive the burrs or waste
and carry them round without forcing them in contact with the teeth of the swift;
and after passing the swift they fall down.
Or the roller may be covered with carding engine clothing.

1 CHARLES THORNES PHILLIPS of Ossett in the County of York Woollen
Merchant 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 :-
The object of my invention is to avoid the waste or loss due to the fine fibres (of
wool, cotton, etc.) being thrown down from the swift immediately after passing the
doffer along with the coarse burr or waste.
For this purpose I place a roller of wood or metal immediately beneath the line
of contact or meeting of the swift and doffer. This roller is placed so close to the
swift, that any light fibres which may be thrown off from the swift as it passes the
doffer are immediately caught on the surface of the roller and brought back close
to the teeth of the swift, so as to be caught by the latter and again carried round
with the swift.
The roller may be of wood or metal, and plain or with longitudinal corrugations.
In the latter case the depressions of the roller will receive the burrs and heavy
coarser waste and carry them past, without forcing them in contact with the teeth
of the swift; and after passing the swift they fall down.
And in order that my invention and the manner in which the same may be
performed may be more readily and clearly understood, I have annexed hereto a
diagrammatic longitudinal section of a part of a carding engine to which my
invention is applied, and in which
a a are the side frames of the carding engine,

page_text: cc the doffer cylinders,
ee the rollers each placed beneath the line of contact of the swift and doffer
working off from the same. The roller e is shewn plain, the roller e¹ with longi-
tudinal corrugations, and both as described close to the respective swifts. The
axles of the rollers are preferably mounted in adjustable bearings, so that they can
be readily adjusted in position if necessary.
By the present system of working the light fibres amongst the waste thrown
down by the swift is usually returned by hand to the feeding board to be again
passed through the machine, which in most instances results in such light fibres
being unevenly distributed amongst the material being carded. By the present
invention the light fibres are returned at once and in a uniform manner, thus to a
great extent diminishing the liability of the cloth being cockled during the process
of milling.
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 carding engines the employment of a roller placed beneath the line of contact
of the swift and the doffer close to the swift for the purpose of catching the light
fibres thrown off from the swift as it passes the doffer and returning them to the
teeth of the swift.
