Improvements in or applicable to Carding Engines.
I, GUILLAUME TURCKX, of 31, Rue de Dison, Verviers, in the Kingdom of
Belgium, Foreman, do hereby declare the nature of this invention and in what
mauner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to carding engines, the object being to automatically and
economically keep the teeth of the doffer constantly clean, and prevent it from
becoming choked.
In carrying out my invention I mount the fancy roller so as to cause it to act
simultaneously on the doffer and on the main carding cylinder, for example by
lowering the bearing of the fancy roller so that the latter will act very lightly on
the doffer without altering the direction of rotation of the three parts, namely the
main cylinder, fancy roller, and doffer. The fancy roller thus performs simul-
taneously the double operation of bringing the wool to the surface of the cylinder
and of continually removing dirt and other impurities from the teeth of the
doffer.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, which represents
a longitudinal elevation of a carding engine in which the fancy roller is mounted
according to my invention.
A is the bearing of the fancy roller adjustable by means of a screw a working
in a flange on a bracket B, the said bearing, and with it the fancy roller, being
moved towards or away from the main cylinder as required. As it is requisite that
the fancy roller should be capable of easy and accurate adjustment in two
directions, that is to say, simultaneously relatively to the main cylinder and to the
doffer, I arrange the bracket B so that it can slide in a support C adapted to the
half-moon or curved framework of the machine, and having a flange through which
works an adjusting screw 6 acting on the bracket B and with it, in a vertical
direction, upon the bearing of the fancy roller. An important result to attain in
this method of mounting and working the fancy roller is to prevent the impurities
detached from the doffer from forming a roll resting on the latter, the constant
removal of which roll by the workman is absolutely necessary, portions of wool and
impurities even then falling back into certain parts of the doffer and considerably
injuring the cards.
To attain this result and also to more easily and completely detach the impurities,
I arrange at each side of the fancy roller and doffer a sheet iron cheek G, and I
also provide two other sheet iron cheeks g with a cover and supported by rods g¹,
the whole constituting a casing G¹ enclosing the fancy roller and the adjacent
worker or roller. I also employ in combination with the doffer a receiver F for the
impurities extracted from the doffer by the fancy roller. Owing to these arrange-
ments I obtain the required ventilation, I prevent it from acting otherwise than on
the front of the doffer, and I prevent evaporation and the escape of the dust and
impurities in a direction other than that of the receiver F.
It is obvious that the constant maintenance of the teeth of the doffer in a clean
condition contributes to keep the main cylinder clean also, and that the improve-
ments hereinbefore described cause the freeing of the fleece and consequently of
the spun material or yarn from the impurities which have hitherto been allowed
to accumulate or fall back into the cards until the periodical stripping by hand,
the time involved in the operation of which is besides considerably economised as
well as the cost of the labour.

page_text: 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 :-
1. A carding engine the fancy roller of which acts simultaneously on the main
cylinder and doffer in combination with a casing enclosing the fancy roller, a
portion of the adjacent worker or roller and the space between the fancy roller
and doffer and with a dust collector F, substantially as hereinbefore described and
for the purpose set forth.
2. In a carding engine the combination of the fancy roller with an adjusting
screw a, a flange on a bracket B and a support C adapted to the half-moon_or
_ curved framework and on which is mounted the bracket B and an adjusting
screw-b-acting on the said bracket, substantially as, and for the purpose, set
forth.
3. The improved carding engine hereinbefore described and illustrated in the
-accompanying drawing.
