'IMPROVEMENTS IN COMBING MACHINES."
RC
"
This invention has reference to improvements in machinery known as Combing
Machines, particularly to the combing machines known as Heilmann's," used in
the preparation of Cotton or other fibrous materials."
The usual method of clearing the needles of a combing machine is by a revolving
or movable brush, placed in a suitable position to clear them after the operation of
combing has taken place. This arrangement causes many inconveniences and
results detrimental to the production of perfect yarn, such as, that of throwing fly,
fluff or dust, about the room and on the machinery, which is liable to be carried
through with the sliver. Another detriment to the use of the revolving brush is,
that to enable it to do its work satisfactorily, the bristles have to be set so deep
into the needles, that at times when revolving they become entangled with and
thus injure the needles, rapidly wearing out the brushes and causing frequent
expensive repairs, as well as the stoppage of the machine; besides, the brush not
always clean in itself, does not clear the needles perfectly, and the combs being
dirty do not perform their work as accurately as desired.
By our improvements the fly, fluff or waste is first conducted to the points of the
combs, is then cleared off easily and perfectly by a doffer or clearer cylinder, the
evils before mentioned being dispensed with.
To accomplish these improvements we employ or provide on one or on both sides
of the needles, clearing plates, bars or knives, made of any suitable metal or other
materials, placed in suitable bearings and attached to the comb block or cylinder.
These clearing plates, bars or knives are so constructed that as the combing
cylinder revolves and after the operation of combing, they are drawn or forced
by mechanical or other means, or fall by gravitation or centrifugal force towards
the points of the combs or needles, by which action the fly, fluff or waste is at once
pushed off near the edges or points of the needles, and as the cylinder revolves it

covered with suitable material, such as, card filleting, inserted wire teeth, bristles,
cloth or other equivalents.
To prevent the plates, bars or knives rising to the edge of the needles just before
and during the operation of combing, we fix suitable guides to keep them to the
bottom of the projecting part of the needles until such operation is completed.
In another arrangement wherein the comb cylinder is provided with one, two, or
more rows of needles, the aforesaid plates, bars or knives are firmly secured to and
form part of the comb cylinder; the clearing action being performed by the needles
being constructed so as to rise or proceed from the comb cylinder immediately
before and during the operation of combing, after which operation they again drop
in, or nearly so, thus leaving the fly, fluff or waste on the edge of the stationary
plates, bars, or knives, which is cleared off by the action of the doffer or clearer
cylinder as before mentioned. The rising and falling of the needles being performed
by suitable eccentric or other motions.
The advantages accruing from these improvements are, that the ordinary clearing
brush with its detrimental effects of dust, dirt, wear and tear are dispensed with,
and the machine made more effective.
