the Office of the Commissioners of Patents, with his Petition, on
the 14th August 1868.-A communication from abroad by Louis
Warnery, of Paris, in the Empire of France.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS APPLICABLE TO MACHINERY
FOR COMBING SILK AND OTHER FIBROUS SUBSTANCES," to be as follows:-
The object of this Invention is to discharge or take off from the combs
or cards of combing machinery the fibrous material in a perfectly pro-
gressive and uniform manner. By a "progessive discharge" it must be
understood, 1st, that the filaments or fibres which are hooked on to the
first row of teeth of the combs or cards are the first to be taken off
therefrom; the filaments or fibres on the other rows of teeth being taken
off row by row in successive or progressive order; 2nd, that each fibre
should be scized or laid hold of by the forward end, and thus taken off
from the combs or cards without being turned over or tangled. By
"uniform discharge" must be understood a discharging or taking-off
operation, which takes place exactly in the same manner throughout the

page_text: whole row of teeth or cards extending across the machine, so that the
minimum speed and penetration of the teeth of the discharging drum
necessary for discharging or taking off the fibres from a row of teeth
may be employed for discharging the comb or card throughout its whole
length. This is effected by guiding, raising, and lowering the combs or
cards in their course or progress under the discharging or taking-off
drum, in such a manner that the teeth or points of the first row of
combs or cards which are placed at an inclination shall be the first to
enter into action with the teeth or pins of the discharging drum and
shall penetrate to the desired depth, while the other rows of teeth or pins
of the combs or cards shall not come into action in the same manner
until after the first have entered, and so on in succession. Moreover,
the teeth of all the rows of combs or cards will remain in contact with
the discharging or taking-off drum only the time necessary to allow the
pins or teeth of such discharging drum by their greater speed to take
hold of the fibrous substance held by the combs or cards. The combs
or cards are secured to an endless chain, strap, or apron, and are placed
in an inclined position. They are provided at each end with bowles or
antifriction wheels, which come into contact with curved guides or rails,
whereby the combs or cards as they pass under the discharging or
taking-off drum are raised or lowered or guided in the required manner
to bring their rows of teeth or pins in succession into contact or action
with the teeth or pins of the discharging or taking-off drum. A rotary
brush is employed for pushing down the fibres into the teeth or pins of
the discharging or taking-off drum so as to form a bat thereon, which
may be removed by hand or otherwise from the discharging or taking-off
drum, when the latter is lifted out of its bearings or out of gear with
the other working parts of the machine.
