Office of the Commissioners of Patents, with his Petition, on the
16th March 1868.-A communication from abroad by Ira Dimock,
of Florence, Hampshire County, in the State of Massachusetts,
United States of North America.
I, PETER JOEL LIVSEY, of the City of Manchester, in the County of
Lancaster, Consulting Engineer and Patent Agent, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
COMBING COTTON AND OTHER FIBROUS MATERIALS," a communication from Ira
Dimock, of Florence, Hampshire County, in the State of Massachusetts,
United States of North America, to be as follows:-
The Invention communicated to me relates to several combinations
and arrangements of mechanism for combing fibrous materials, and
consist in mounting the " lap" on a roller which is the axis of an
oscillating frame carrying a pair of feed rollers, or one feed roller and
a smooth bar, which act as nippers alone or in combination with a
"detaching comb," or a pair of pinchers are used in addition to the feed
rollers, or feed roller and smooth bar. On a level with the lap axis a
shaft is placed which forms the axis of a second oscillating frame

page_text: carrying a pair of pinchers which are opened and closed by a cam on the
said shaft. The first-mentioned oscillating frame can move to bring the
end of the "lap" so as to be operated upon by a rotary combing drum
and then present the combed ends to the pinchers carried by the second
oscillating frame which closes upon them, so that by the movement of
both oscillating frames the fibres thus pinched are detached from the
"lap" and their tail ends are combed in passing through the detaching
comb. The detaching pincher frame can oscillate to bring the tails of
the detached fibres past and against the rotary combing drum and then
deposit them on a doffer upon and against which a pinching bar brush
or its equivalent may be worked to prevent the return of the fibres by
the back movement of the pinchers. The combed fibres accumulated
upon the doffer are removed from it by rollers in the form of a sliver.
The noil is removed from the rotary comb drum by a rotary brush and
transferred to a doffer from which it is removed in a sliver by a doffing
comb.
Another combination consists of an oscillating frame carrying feeding
rollers and detaching comb alone, or these and pinchers which present
the end of the lap to a combing drum, same as the oscillating frame
herein first mentioned, but instead of the combed ends of the lap being
detached by oscillating pinchers as in the first modification described,
they are removed and drawn through the detaching comb by fixed
rotary rollers which may have a forward and reversed rotary movement
if required. The modification last described may be made double as
to the oscillating frame, one rotary combing drum acting for both.
Another combination consists of two sets of oscillating pincher frames,
one pair of pinchers detaches the uncombed tuft from the lap presented
by feed rollers, drawing the tail of the tuft through a detaching comb
and carries the tuft past a rotary combing drum and delivers the tail
ends of the tuft into the second pair of pinchers, which will thus carry
the front ends of the tuft past the combing drum and deposit them upon
a doffer or "licker-in." The oscillating pincher frames in each com-
bination may be actuated by cams or by crank motions; the latter are
especially preferred in the first modification herein described.
