page_text: LETTERS PATENT to Robert Henry Hampson, of Heaton Norris, in
the County of Lancaster, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF MACHINERY OR APPARATUS USED IN THE MANUFACTURE OF
CLEANING WASTE EMPLOYED FOR CLEANING LOCOMOTIVE ENGINES AND FOR
OTHER LIKE PURPOSES."
Sealed the 6th December 1872, and dated the 4th October 1872.
PROVISIONAL SPECIFICATION left by the said Robert Henry Hampson
at the Office of the Commissioners of Patents, with his Petition,
on the 4th October 1872.
I, ROBERT HENRY HAMPSON, of Heaton Norris, in the County of
Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY OR APPARATUS USED IN
THE MANUFACTURE OF CLEANING WASTE EMPLOYED FOR CLEANING LOCOMOTIVE
ENGINES AND FOR OTHER LIKE PURPOSES," to be as follows:-
This Invention relates to the machinery used for the manufacture
of cleaning waste (employed for cleaning locomotive engines or other
machinery) from hard waste, cop bottoms, and other similar cotton
waste, and consists principally in the combination in one machine of
-

page_text: the picking and finishing apparatus, so that the hard waste may be
fed into one end of the machine, and the lap of cleaning waste will be
delivered ready for use at the other at one operation.
The waste is taken in by a pair of feed rollers and delivered on to the
first cylinder, which is covered with pins or teeth and which effects the
picking and separation of the waste, the dirt falling through a grid
beneath and being drawn off by means of a fan. This first cylinder
then delivers the waste on to a second cylinder driven in the reverse
direction, and covered with pins set closer together and somewhat finer
than those of the first cylinder, a clearer roller being placed in the
angle between the two cylinders. The second cylinder is provided with
strippers and clearer rollers for carding the waste, and delivers the same
on to a doffing cylinder, a clearer roller being placed in the angle
beneath the second and doffing cylinders. The waste is removed from
the dofing cylinder by means of a pair of doffing rollers, and is wound
into a lap by means of a drum.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Henry Hampson in the Great Seal Patent
Office on the 4th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT 2
HENRY HAMPSON, of Heaton Norris, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of October, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-2
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Robert Henry Hampson, Her special
license that I the said Robert Henry Hampson, my executors,
administrators, and assigns, or such others as I, the said Robert
Henry Hampson, my executors, administrators, and assigns, should at any 3
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 United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR THE

page_text: MANUFACTURE OF CLEANING WASTE," upon the condition (amongst others)
that I, the said Robert Henry Hampson, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Lettors
Patent.
NOW KNOW YE, that I, the said Robert Henry Hampson, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, and accompanying Drawings (that is to
say) :-
This Invention relates to the machinery used for the manufacture
of the cleaning waste (employed for cleaning locomotive engines and
other machinery) from hard waste, cop bottoms, card room sweepings,
and other similar cotton waste, and consists principally in the com-
bination in one machine of the picking and finishing apparatus, so that
the hard waste may be fed into one end of the machine, and the lap
of cleaning waste will be delivered ready for use at the other at one
operation.
The waste is taken in by a pair of feed rollers and delivered on to
the first cylinder, which is covered with pins or teeth and which effects
the picking and separation of the waste, the dirt falling through a grid
beneath and being drawn off by means of a fan. This first cylinder then
delivers the waste on to a second cylinder driven in the reverse direction,
and covered with pins set closer together and somewhat finer than those
of the first cylinder, a clearer roller being placed in the angle between
the two cylinders. The second cylinder is provided with strippers and
clearer rollers for carding the waste, and delivers the same on to a doffing
cylinder, a clearer being placed in the angle beneath the second and
doffing cylinders. The waste is removed from the doffing cylinder by
means of a pair of doffing rollers, and is wound into a lap by means of a
drum.
Such being the nature and object of my said Invention for Improve-
ments in the Construction of Machinery or Apparatus for the Manu-
facture of Cleaning Waste," I will now proceed to describe more in

page_text: detail the manner in which the same is to be or may be performed
or carried into practical effect, and in order that the same may be clearly
understood I have annexed hereunto a Sheet of Drawings illustrative
thereof, and have marked the same with figures and letters of reference
corresponding with those in the following explanation thereof:--
In the annexed Drawing, Fig. 1 is a sectional elevation; Fig. 2 a side
view; and Fig. 3 a view of the feeding end of a waste picking and
finishing machine made according to my Invention. a, a, is the main
framing of the machine; b, b, a travelling feeding apron on which the
hard waste is laid; and c, c, a pair of fluted feeding rollers, by means
of which it is delivered to the first or "picking" cylinder d, d, which is
covered with pins or teeth of the form and size represented at Fig. 4.
The top feeding roller is weighted by means of the lever and weight e, e,
so as not to allow the pins or teeth of the cylinder d, d, to take in too
large a quantity of wasto at a time without separating it; f,f, is a
curved grid beneath the cylinder d, d, through which the dirt falls, and
the dust and lighter portion being drawn off through the side flues I, I,
by means of the fan h, h.
Figs. 5 and 6 show an arrangement by means of which the grid,
may be made, so that its fineness can be altered to suit different qualities
of work. The grid is made in two sections fand*, and when these
sections are so placed that the bars of the two correspond, as at Fig. 5,
the full opening between the bars is available, but on sliding one section
over the other, so that the bars in one section come opposite to the
spaces in the other (see Fig. 6), the openings become proportionately
reduced. The first cylinder d, d, delivers the waste on to a second
cylinder i, i, driven rather faster in the reverse direction, and covered
with pins set closer together and somewhat finer than those of the first
cylinder (see Fig. 7, full size view), a clearer roller k, k, being placed in
the angle between the two cylinders. The waste is here carded by
means of the strippers 1, 1, and clearer rollers m, m, and is then delivered
on to the doffing cylinder », ", a clearing roller o, o, being also placed
in the angle beneath the second and doffing cylinders i and n.
Fig. 8 is a full sized view of the teeth of the doffer cylinder and the
strippers and clearers. p, p, is a pair of doffing rollers for removing
the waste from the doffing cylinder; and q, q, is the drum for winding
or rolling the finished waste into a lap r, r, as it is delivered by the

page_text: ▸
doffing rollers p, p; 8, 8, is a door for cleaning out any dirt that may
accumulate beneath the second cylinder i, i. The two main cylinders
are driven by straps t, t, and u, u, from a drum above, and transmit
motion to the various parts of the machine by means of chains v, v, and
straps 10, 10. The bottom feeding roller is driven by the spur wheel x, x,
and pinion y, y, the latter being mounted in a lever z, z, by means of
which it can be thrown out of action at any time if required.
It will be evident that by the use of additional finishing cylinders
with still finer teeth the waste can be carded up to any degree of
fineness.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I wish it to be understood that I
claim as my Invention the general construction and arrangement of the
machine, and more especially I claim the combination in one machine
of the pickering and finishing apparatus, substantially in the manner
above described and illustrated by the Drawings annexed.
In witness whereof, I, the said Robert Henry Hampson, have
hereunto set my hand and seal, this Second day of April, in
the year of our Lord One thousand eight hundred and seventy-
three.
