I, EDWARD TAVERNIER, of the Firm of E. Tavernier and Company,
of Rue Beauharnais, Lille, in the Empire of France, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
COMBING WOOL, COTTON, AND OTHER FIBROUS SUBSTANCES," to be as follows :-
The improvements, as hereafter described, are based upon the Patent
obtained by me and Henry Walton Whitehead on the 1st November
1866, No. 2882, which was for improvements on the combing machine
known as "Nobles."
My present improvements consist, first, in fitting a pressing frame
on the inside of the main frame or on an additional frame on an ad-

page_text: justable centre or pivot. The frame has at its front end a square or
other shaped opening, in which a plate is made to rise and fall as
required. The plate carries a guide pin over which a spring is passed,
and which when acting upon the plate causes the plate to hold the
fibre in the frame between it and the pins or points. This holding
and pressing on the ends of the fed slivers prevents the divergency
of the fed slivers protruding out of the circular comb and produces
a regular and compact fringe or bat free of solution of continuity. The
spring is surmounted by a nut and cap. The lower end of the cap
is partially cut away to form a shoulder so that if turned in one direction
it bears upon the frame and retains the plate in a raised position.
The back end of the frame is fitted with a spring for giving the
required downward pressure of the front end in order to keep it in
contact with the lifting pin or bolt, which rides upon an incline as
usual.
The second part of my Invention consists in the employment of
needles or points of bayonet shape on the outside rotating ring. The
needles project vertically beyond the periphery of the ring.
The third part of the Invention consists in the employment of a
guard comb fitted to a plate which is caused to rise and fall, the rising
motion being obtained by two inclines fitted to the main frame. The
needles of the rising plate may be secured thereto either on the top
or to the side in any suitable manner. The bottom of the rising plate
is fitted with rollers to ride upon inclines to facilitate its action and
is kept vertical by fixed pins passing through slots. The comb plates
are fitted all round the ring, and their meeting ends are formed
to overlap one another so as to ensure all the needles being of equal
distances apart.
The next part of my Invention consists in the employment of the
porcupine roller of a slightly concave and conical form, and which is
fitted with coarse and fine needles or points, and in placing it in such
a manner that the points thereon shall be in contact with the receiving
needles and take the material under operation from them.
The last part of my Invention consists in the employment of fixed
plates -pressed upon by springs, screws, or other appliance to act upon

page_text: the sliver and force it down between the needles in order to keep
one end of the fibres solid in the receiving comb during the operation
of the combing porcupine on the other end of the fibres. The plate
is curved at each end to facilitate the sliver entering and leaving.
