Improvements appertaining to Machinery for Carding Wool and other.
Fibrous Substances.
We, JoHN FRANCIS WHITE and JOHN HURRY, both of 168, Thornton Road,
Bradford, in the County of York, Engineers, 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, that is to say:-
-
In connection with machinery for carding fibrous substances of the class wherein
such substances are operated upon by means for forming them into one or more
series of threads or slivers, it is well known that the two outermost or outside
threads or slivers are at all times more or less faulty by reason of the irregular
supply of the fibrous substances at these outer edges, so that at all times the
fibres forming these outer threads or slivers are collected and thrown back to
again pass through the carding machine, because their irregular thicknesses pre-
clude their further use in the subsequent processes.
To collect these outside threads or slivers and conduct or convey them back
to re-enter the carding machines as regularly as they are produced, and by means
which require little if any care on the part of the operative while performing
such functions, is the object of our invention, and this object we attain by the
apparatus hereinafter described and as illustrated by the annexed sheet of drawings
in which—
Fig. 1 is an elevation shewing the method of mounting our apparatus in con-
nection with a carding machine.
Fig. 2 is a view of certain of the parts as seen from above.
Figs. 3 and 4 are sectional and end views respectively of a nozzle for the
delivery end of the receptacles, hereinafter explained.
Figs. 5 and 6 are similar views to Figs. 3 and 4 but are illustrative of a mouth
piece hereinafter described.
In accordance with our invention we arrange those threads or slivers which are
at the outer edges of the respective series of threads or slivers a or ¹ to be
received by their respective tubular receptacles a a¹, these receptacles a al being
mounted on the sides of the machine b as shown, (thus in machines having two
series of slivers or threads a and there will be two separate and distinct
receptacles à on one side of said machine, and two a¹ on the other side thereof),
so that they may be arranged to lead into air tubes cc through each of which passes
a current of air of sufficient force to carry with it the thread or sliver received
or admitted through its respective receptacles a or a¹, to the front end of the
machine b, where said threads are deposited into the feed box to be re-weighed
before again being fed into the carding machine.
The parts of the tubes c c at which the receptacles a a¹ enter them, are made
less in area in cross section than are the other parts, by which means on the
currents of air from a fan or blower (not shown as any of the well known fans
may be employed) passing in the direction indicated by the arrow d, supplementary

page_text: currents are caused to pass down the receptacles a a¹ carrying with them the
threads or slivers of fibrous substance as desired.
The orifices f and f' (one of which is secured to the upper end of each of the
receptacles a or a¹) for receiving the threads or slivers are of the formation
shown by Figs. 5 and 6 while the openings leading from the receptacles a a¹
to the tubes c c are of the shape shown by Figs. 3 and 4, the lip on each pre-
venting the currents of air from having a tendency to pass up the tubes a a
instead of along the tubesc, while it also enables the threads or slivers entering
at this part to have more freedom of passage.
Appropriate damper arrangements are employed for regulating the currents
of air as required.
our said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In connection with carding machines for treating fibrous substances, means
whereby the faulty ends, slivers or threads are conveyed to again pass through
said machines substantially as herein specified.
.
2. In connection with catding machines of the class described thread or sliver
conveying means and parts forming the mouth pieces and outlet orifices arranged
in combination substantially as herein set forth.
