IMPROVED MACHINERY FOR FEEDING CARDING ENGINES
Year: 1874

page_text: LETTERS PATENT to James Armitage; of Steps, near Huddersfield,
in the County of York, Scribbling Engineer, for the Invention of
"IMPROVED MACHINERY FOR FEEDING CARDING ENGINES."
Scaled the 11th December 1874, and dated the 21st July 1874.
PROVISIONAL SPECIFICATION left by the said James Armitage at
the Office of the Commissioners of Patents, with his Petition, on
the 21st July 1874.
I, JAMES ARMITAGE, of Steps, near Huddersfield, in the County, of
York, Scribbling Engineer, do hereby declare the nature of the said
Invention for "IMPROVED MACHINERY FOR FEEDING CARDING ENGINES," to
be as follows:-
The object of this Invention is to feed carding engines more evenly
than heretofore, and without the necessity for weighing out the material.
In carrying out this object I use a feed hopper provided with a pinned
drum or its equivalent for taking up the teazed wool or other fibre, and
a stripper or clearer working in connection therewith for delivering the
fibrous material in a continuous fleecy sheet to the feed apron of the

page_text: carding engine. The bottom of the hopper consists as usual of an
endless apron, which is set at about a level with the axis of the
drum. The hopper is also provided with a vibrating board or plate for
preventing the escape of the fibrous material over the top of the take-up
drum.
The motion for driving this drum or its equivalent I derive from the
carding engine, taking it by preference from the doffer shaft by any
suitable arrangement of driving gear. The following will be found
suitable for the purpose:-A horizontal shaft mounted in bracket
bearings or one side of the frame of the carding engine is provided at
its opposite ends with bevil pinions. Into one of these gears a bevil
pinion on the doffer shaft, and into the other gears a bevil wheel which
transmits motion through a diagonal shaft fitted with bevil pinions to a
bevil wheel keyed on the axle of the take-up drum. A band or equi-
valent means may be used for transmitting the motion from the drum
axle to the stripper or clearer, the endless apron of the feed hopper, and
the vibrating backing board or plate.
The rotary motion of the drum, and consequently the rate of take up
and delivery of the wool or other fibre, being by the above-mentioned
means made to depend upon the speed of the carding engine, the feed
will be increased or diminished in exact proportion to the variation in
the working capacity of the carding engine caused by the diminished or
increased motive power available for driving the machinery.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
"
filed by the said James Armitage in the Great Seal Patent Office 25
on the 21st January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
ARMITAGE, of Steps, near Huddersfield, in the County of York,
Scribbling Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 30
Letters Patent, bearing date the Twenty-first day of July, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-

:
The motion for driving the feeding apparatus I derive from the carding
engine, taking it by preference from the doffer shaft by any suitable
arrangement of driving gear, or from the axle of the driven feed roller.
When driving from the doffer shaft the following arrangement will be
found suitable for the purpose. A horizontal shaft G, Fig. 1, mounted
in bracket bearings on one side of the frame of the carding engine is
provided at its opposite ends with bevil pinions. Into one of these gears
a bevil pinion on the doffer shaft, and into the other pinion 9 gears a
bevil wheel mounted loosely on the axle of the feed roller H.. This.
wheel / transmits motion through a diagonal shaft I fitted at its opposite
ends with bevil pinions i to a bevil wheel keyed on the axle of the
take-up drum B; or if this wheel h were keyed to its axle it would
serve to transmit motion to the drum from the driven feed roller of the
carding engine. From a pulley on the drum axle a band c passes to a
pulley on the axle of the stripper or clearer C for the purpose of trans-
mitting rotary motion thereto in the direction of the arrow, Fig. 2, and
thereby enabling it to strip or clear the drum teeth or pins. The endless
apron E, E, of the feed hopper is driven by a band e from a pulley on
the axle of the drum B in the direction of the arrow, Fig. 2. The
vibrating backing board or plate F is actuated by means of a crank
rod worked by a crank pin on a disc f', to the axle of which is keyed
a band pulley f³. This pulley receives a band f³ from a pulley on the
axle of the stripper C, and thus all the acting parts of the feed apparatus
derive their motions from the carding engine to which the apparatus is.
fitted.
As the rate of take up and delivery of the wool or other fibre is thus
made to depend upon the speed of the carding engine the feed will be
increased or diminished in exact proportion to the variation in the
working capacity of the carding engine caused by the diminished or
increased motive power available for driving the machinery.
Having now set forth the nature of my Invention of "Improved
Machinery for Feeding Carding Engines," and explained the manner of;
carrying the same into effect, I wish it to be understood that, under the
above in part recited Letters Patent I claim the application to carding

five.
