IMPROVEMENTS IN MACHINERY OR APPARATUS FOR FEEDING CARDING ENGINES
Year: 1875

page_text: LETTERS PATENT to Edward Taylor Sykes, of Huddersfield, in the
County of York, Woollen Manufacturer, for the Invention of
" IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR FEEDING CARDING
ENGINES."
Sealed the 26th October 1875, and dated the 30th April 1875..
PROVISIONAL SPECIFICATION left by the said Edward Taylor Sykes
at the Office of the Commissioners of Patents, with his Petition,
on the 30th April 1875.
I, EDWARD TAYLOR SYKES, of Huddersfield, in the County of York,
3 Woollen Manufacturer, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR FEEDING CARDING
ENGINES," to be as follows:-
This Invention relates to that class of machinery known as Evans'
and King's "feed," and the object of my improvements is to effect
greater nicety in the weighing of the material, and regularity in de-.
positing the same on the feed apron.

page_text: I construct the fulcrums of the weighted levers with knife edges, and
place them on their supports in such manner that they shall be free to
work without frictional resistance. The end of one of the levers is
clongated in such manner that as soon as the scale pan has received the
required amount of material and is depressed thereby, the elongated
lever aforesaid will remove the support of the strap guide rod of the
feeding apparatus, and the supply of the material to the scale pan
ceases.
For upsetting the scale pan I employ a cam on one end of the roller
carrying the feed apron, which cam acts on one end of a bell-crank lever,
the other end of which (carrying a friction pulley) comes into contact
with an incline on the scale pan and upsets the same, thus depositing
the material thercon on to the feed apron.
It will be seen that if the supply of material to the scale pan is
irregular and the pan is overbalanced too soon the supply is stopped, but
that the pan is not upset and the material deposited on the feed apron
until the proper time.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Taylor Sykes in the Great Seal Patent
Office on the 30th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
TAYLOR SYKES, of Huddersfield, in the County of York, Woollen Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Edward Taylor Sykes,
Her special licence that I, the said Edward Taylor Sykes, my
executors, administrators, and assigns, or such others as I, the said
Edward Taylor Sykes, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the

page_text: "
Figs. 1 and 2 are opposite side elevations of an Evans' and King's
feed," and shew such parts of the machinery as are necessary to illus-
trate my improvements.
-
A is the scale pan suspended between the weighted levers B on knife
edge pivots by means of links A₁ and round pins a, which are secured to
a rod underneath the scale pan. The fulcrums 6 of the weighted levers
are constructed with knife edges from side to side supported within a
hollow tube, and are always kept in a weighing position by the stop H,
which stop interposes immediately after the disengagement of the strap
guide rod, so that there shall be as little frictional resistance as possible
to interfere with the process of weighing. The end of the lever B' is
elongated, so that as soon as the scale pan is depressed this elongated
end will remove the support C of the strap guide rod by the act of
weighing, and at the same time B¹ coming in contact with the pin I on
the arm B² the supply of material to the scale pan ceases.
For upsetting the scale pan I employ a tappet finger or arm D, which
acts on the end E of the bell-crank lever E, the other end of which carries
a friction pulley F. This friction pulley comes in contact with the
incline G underneath the scale pan and upsets the same, depositing the
material on the feed apron, after which the bell-crank lever falls back,
and the scale pan returns by its own balance.
Instead of the finger herein shewn and described, other means may
be employed for actuating the bell-crank lever, thereby dispensing with
the hook tooth wheel previously used for this purpose.
Having thus described the nature of my said Invention, and shewn
by Drawings how the same is to be or may be performed or carried into
practice, I would have it understood that I do not confine myself to the
precise details herein shewn and described, as the same may be varied
without departing from the principle of my Invention, but what I claim
and consider to be new is,―
Firstly. The combination of the incline and bell-crank lever, together
with means for actuating the same, as and for the purpose substantially
as herein set forth.
Secondly. The method of suspending the scale pan, substantially as
herein shewn and described.

page_text: Thirdly. The stop H and the stud or pin on the arm B, and the
balancing of scale pan so that its return is self-acting, and thereby
dispensing with the hook tooth wheel and all its motive connections.
In witness whereof, I, the said Edward Taylor Sykes, have here-
unto set my hand and seal, this Twenty-eighth day of October,
in the year of our Lord One thousand eight hundred and seventy-
five.
EDWARD TAYLOR SYKES. (L.S.)
