Year: 1861

page_text: LETTERS PATENT to Eli Stott, of Ashton-under-Lyne, in the County of
Lancaster, Machinist, for the Invention of "IMPROVEMENTS IN APPARATUS
USED FOR COLLECTING AND REMOVING THE WASTE AND DIRT WHICH OCCURS IN
THE PROCESS OF SPINNING COTTON AND OTHER FIBROUS MATERIALS."
Sealed the 13th June 1862, and dated the 19th December 1861.
PROVISIONAL SPECIFICATION left by the said Eli Stott at the Office of
the Commissioners of Patents, with his Petition, on the 19th December
1861.
I, ELI STOTT, of Ashton-under-Lyne, in the County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS USED FOR COLLECTING AND REMOVING THE WASTE AND DIRT
WHICH OCCURS IN THE PROCESS OF SPINNING COTTON AND OTHER FIBROUS MATERIALS,"
to be as follows:-
My improvements relate to the apparatus generally used with the spinning
machines called mules (for spinning cotton and other fibrous materials) for
the purpose of collecting and removing the waste and dirt which accrues
during that process.
My first improvement consists in the mode of constructing and arranging
the brackets for supporting the scavenger rollers, by which the waste and dirt
is collected and removed from the carriage boards of the mule. In the
ordinary mode of supporting the scavenger roller, a bracket turning on a

page_text: centre fixed to the roller beam is made use of, which allows the scavenger
roller to accommodate itself to the slope of the carriage boards. From this
construction accidents and damage frequently occur by loose articles falling
on to the carriage boards, which are caught and jammed by the scavenger
roller as the carriage runs in.
In my improved mode of constructing and arranging the bracket, a spring
or weight (acting on a lever) is made use of which holds the scavenger roller
up to its place during its ordinary working, but which enables it to yield to
any extraordinary pressure, which may accidently occur, and thus prevent
damage or breakage to the machinery.
My second improvement consists in the application of mechanism to the
brackets which support the scavenger roller, by which the scavenger roller is
raised so as to be entirely clear of the carriage boards during the running in of
the carriage, but on the carriage drawing out, it is allowed to drop on to the
carriage boards, and so collect and remove the waste and dirt.
My third improvement consists in the application of certain mechanism by
which the scavenger roller is not only made to cleanse the carriage boards
from the waste and dirt, but also to cleanse the waste and dirt from the stands
and front of the roller beam. This I effect by means of a revolving cam
or cams or eccentrics, which acting on a lever or levers connected with the
axis or shaft, on which are fixed the brackets which support the scavenger
rollers, the scavenger roller is alternately raised to a proper position to
cleanse the stands and front of the roller beam, and alternately lowered to the
proper position to cleanse the carriage boards. When the scavenger roller is
in the position to cleanse the stands and roller beam, rotatory motion is com-
municated to it by means of pinions or otherwise; but this motion ceases when
the scavenger roller is lowered down, as it is not necessary when the carriage
boards only are to be cleansed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Eli Stott in the Great Seal Patent Office on the 19th June
1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELI
STOTT, of Ashton-under-Lyne, in the County of Lancaster, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our

page_text: Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Eli Stott, Her special license that I, the said Eli Stott, my
executors, administrators, and assigns, or such others as I, the said Eli
Stott, 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 United Kingdom of Great Britain and Ireland, the
Channell Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN
APPARATUS USED FOR COLLECTING AND REMOVING THE WASTE AND DIRT WHICH
OCCURS IN THE PROCESS OF SPINNING COTTON AND OTHER FIBROUS MATERIALS," upon
the condition (amongst others) that I, the said Eli Stott, 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
Letters Patent.
NOW KNOW YE, that I, the said Eli Stott, do hereby declare the
nature of my said Invention, and what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and the accompanying Drawing (that is to say) :-
:-
My first improvement relates to the mode of constructing and arranging
the brackets for supporting the scavenger rollers, by which the waste and dirt
are collected and removed from the carriage boards of the mule. In the
ordinary mode of supporting the scavenger roller, a bracket turning on a
centre fixed to the roller beam is made use of, which allows the scavenger
roller to accomodate itself to the slope of the carriage boards, but which is
in other respects firm and unyielding. From this construction accidents and
damage frequently occur by loose articles falling on to the carriage boards,
which are caught and jammed by the scavenger roller as the carriage
runs in.
My first improvement consists in constructing and arranging the brackets
so that the scavenger roller can yield and give way when any extraordinary
5 pressure is opposed to it, and so prevent damage and breakage of the
machinery..
My second improvement consists in the application of mechanism, by which
the brackets (and consequently the scavenger roller) is raised so as to be
entirely clear of the carriage boards during the running in of the carriage;

page_text: but on the carriage drawing out, the scavenger roller falls on to the carriage
boards, and collects and removes the waste and the dirt as the carriage recedes
from the roller beam, instead of the ordinary mode in which the scavenger
roller first runs up the carriage boards as the carriage completes its running
in (and so drives the waste and dirt up to the spindles), and afterwards passes
down the carriage boards as the carriage recedes from the roller beam.
My third improvement relates to the application of certain mechanism by
which the scavenger roller not only cleanses the carriage boards from waste
and dirt, but also cleanses the waste and dirt from the stands and front of the
roller beam.
In order to make my Invention more clearly understood, I have hereunto
annexed a Sheet of Drawings, to which the following description relates, in
which the same letters of reference, or letters and figures conjoined indicate
the same parts of the machinery or apparatus, and in which those parts of the
machinery which do not relate to my Invention are omitted in order to avoid
confusion.
The first mode of carrying out my first improvement will be understood
from Figs. 1 and 2, Fig. 1 represents the yielding bracket in its usual position
when the mule is at work, and Fig. 2 represents the same bracket when it
has been forced backwards in consequence of some obstacle (a clearer for
instance) having fallen on to the carriage board, and been intercepted betwixt
the scavenger roller and the spindles. A, A, section of the roller beam of the
mule; A 1, fixing, attached to the roller beam; B, B, a short lever turning
on a joint A 2 on the fixing A1; B 1, a lump or weight on the lever B, B,
which tends to retain it in the position shewn in Fig. 1 by means of a flat or
stop on the fixing A 1, which allows the lever B, B, to yield backwards, but
not to move forward from the position shewn in the Drawing; C, C, an arm
or lever turning on the pin or joint B 2 on the lever B; C 1, scavenger roller,
-the pivots of which turn in filbows at the end of the arm C, C. At the other
end of the arm C, C, is the adjusting screw C 2, by which the height of the
scavenger roller C1 is adjusted to the carriage boards of the mule. The
scavenger rollers are usually made in length of about four to five feet each,
and consequently a number of the fixings A'1, levers B, B, and arms C, C,
will be required, according to the number of lengths of the rollers, which will
depend on the length of the mule. In Fig. 2, D represents a section of a
portion of the mule carriage; D 1, a part of one of the spindles; D 2, a top
clearer, fallen on to the carriage board, and caught or jammed betwixt the
scavenger roller C 1, and the spindle D 1 at the run in of the carriage. In
this case great damage would occur by the inevitable breakage of the

page_text: machinery, unless the scavenger roller is allowed to give way by the action of
the yielding bracket B, B. A second mode of carrying out my first improve-
ment is shewn in Fig. 4. A, A, section of the roller beam, as before; A 3, a
fixing attached to the roller beam; C3, C3, an arm or lever turning on the
pin A4 on the fixing A 3; C4, C4, a slot lengthwise of the arm C 3, C 3.
At the farther end of this slot is a recess, by means of which the arm CS
turns on the pin A 4, where it is retained by its weight and the weight of the
scavenger roller, which supply the place of the weight B 1, shewn in Figs. 1
and 2; C 1, scavenger roller; and C2, adjusting screw, as before. In case
of any article falling on to the carriage board and getting jammed by the
scavenger roller, the pin A 4 is forced out of the recess into the slot C 4, and
by this means the arm C 3, C 3, and scavenger roller C1 are enabled to yield
and give way, and so prevent damage to the machinery. When the obstacle
is removed, the arm C-3, C3, is placed in its position by the operative.
Fig. 3 represents an improvement or variation of the mode shewn in Fig. 4,
to which the whole arrangement is similar with the exception of the spring C 5,
which is placed in the slot C4, C-4; and attached at one end to the
arm C3, C 3, whilst the other end is curved so as to embrace the pin A 4.
any obstacle occurring betwixt the scavenger roller and the spindles, the
spring C 5 assists in retaining the arm C3, C3, but allows the scavenger
roller C1 and arm C 3 to be forced backwards, and so prevent damage to the
inachinery.
On
Fig. 5 represents another variation in the mode of carrying out my first
improvement. A, A, section of the roller beam, and A 1, fixing attached to
the same, as before. From the joint and pin A 2 on this fixing depends the
arm B 3; this joint allows the arm B 3 to move backwards only, and retains
it from moving forward by means of a stop. At the lower end of this arm is
a joint B 4, on which turns the arm or lever C, C; this arm carries the
scavenger roller C 1, the pivots of which turn in filbows at the end of the
arm C, C, at the other end of which is the adjusting screw C 2, as before;
B5 a spring one end of which is attached to the roller beam A, A, and the
other end to the arm B 3, holding the apparatus in the position shewn in the
Figure. This spring may be made of wire or india-rubber, or other material
sufficiently elastic. On the scavenger roller encountering an obstacle on the
carriage board, the spring B 5 yields to the pressure and allows the scavenger
roller to be forced backwards without any damage being done to the
machinery. I do not, however, confine myself to these several modes of
carrying out this part of my Invention, but vary the construction and arrange-
ment of the yielding bracket, which may be done in other ways besides those

page_text: described, and still producing the same useful result of preventing damage to
-the machinery from articles falling on to the carriage boards.
My second improvement will be understood from Fig. 6, in which A, A,
represents a section of the roller beam; D, D, a section of the carriage; and
D1, D1, a spindle, as before; E, E, an arm or lever on a shaft or axis E 1,
which turns in filbows on brackets attached to the roller beam A, A; E 3, a
catch turning on a pin on the bracket E 4, attached to the roller beam A, A;
this catch E 3, when in actions, retains the arm E, E, in the position shewn in
the Figure by means of a projection E 2 fixed upon it; C 1 the scavenger
roller (as before), the pivots of which turn in filbows at the end of the arm E, E;
D 3, D3, a curved incline attached to the back of the carriage, which when
the carriage draws out lifts the arm E, E, and scavenger roller C1 into the
position shewn in the Figure, but when the carriage runs in passes on one
side of the tail of the catch E 3; D 4, a pin or stud on the curved incline D 3;
which when the carriage runs in to the end of its course, comes in contact
with the tail of the catch E 3, which action detaches the catch from the
arm E, E, which descends, and with it the scavenger roller C 1, which falls
on to the carriage boards at about the point D 5, and on the carriage drawing
out, collects and removes the dirt and waste which has fallen upon it.
My third improvement will be understood from Figs. 7 and 8, in which
Fig. 7 represents an elevation, and Fig. 8 a plan of the apparatus; D, D,
section of the mule carriage, and D 1, a spindle as before; F, F, fixing attached
to the under side of the carriage, from which depends a stud, on which turns
the worm wheel F 1, F 1, on the upper surface of this worm wheel are two
projecting rims F 2 and F3; F4 and F 6, two levers turning on the axis
G as a centre, these levers are weighted at the ends F5 and F 7, so that
the opposite ends have always a tendency to rise on the lever; F 4 is a pro-
jection, by which it is acted upon by the rim F 2, and the lever F 6 has also
a projection, by which it is acted upon by the rim F 3. These two rims
have each a notch or gap in them into which the projections descending
the opposite ends of the levers are raised; G, G, an axis on which is the
worm G 1, which takes into the worm wheel F 1, F 1; G 2, ratchet wheel
on the axis G, G, and G 3 lever and catch by which the axis G, G, is actuated;
H, H, an upright shaft supported by brackets H 1, H 1, from the sampson
H2, H2, (shewn by the dotted lines in the Figures). At the lower part
of this shaft are fixed two arms or levers H3 and H 4, which are acted upon
by the catches F8 and F 9, (at the ends of the levers F4 and F 6). At
the upper end of the shaft H, H, is an arm II 5, to which is attached a chain
or band, the other end of which passes round, and is attached to the pulley I-2

page_text: on the shaft I 1, which is supported by bearings from the roller beam A, A.
This shaft carries a number of arms, one of which is shewn at I, which support
the scavenger roller C 1 in filbows, as before described; H 6 adjustable stud
on the sampson H2, H2, on which the lever G 3 strikes on the running
in of the carriage, and by that means actuates the ratched wheel G 2, the
axis G, and worm G 1, which last again actuates the worm wheel F 1, F 1.
By means of the rims F 2 and F3 (on the worm wheel F 1) the catches
F 8 and F 9, are raised at intervals so as to act as the carriage draws out
upon the arms or levers H 3 and H 4, the catch F8 acting upon the arm
H3, and the catch F9 acting upon the arm H 4. By this means the upright
shaft H, H, is at intervals turned partially round backwards and forwards
when it is in the position shewn in the Figure, the arm H 5 having slackened
the chain or band, the arm I, and scavenger roller C1 are in the position
to cleanse and remove the waste and dirt from the carriage boards, but when
the upright shaft H, H, is turned the contrary way, the chain or band is
tightened and acting upon the shaft I 1, by means of the pulley I 2, the arm I
and scavenger roller C 1, are raised into the position shewn by dotted lines
at I 3, and C 1, in which position the scavenger roller C 1, (which is made
to revolve by means of a pinion which geers into a carrier wheel driven by
another pinion on the front roller) cleanses and removes the waste and dirt
from the stands, and front of the roller beam, which being performed, the
scavenger roller C 1, by the action of the worm wheel F 1, and levers F 4,
and F 6, is again lowered to its first position and cleanses the carriage boards
as before; H7, locking cam, on the upright shaft H, H, which is acted upon
by a bowl on the locking lever H 8, which turns on a stud on the sampson
leg H 2. The use of this locking cam is to retain the upright shaft H, H,
in the position in which it is alternately placed by the action of the
mechanism described; I do not however confine myself to the precise con-
struction and arrangement of the apparatus, as these may be varied. The
scale of the Drawings is marked thereon, but must be varied as circumstances
may require.
Having thus described the nature of my Invention and the manner in
which the same is to be performed, I hereby declare that what I claim as
new and of my Invention is as follows:-
First, I claim the application and adaptation of the yielding bracket to the
purpose of supporting the scavenger roller (for cleansing and removing the
waste and dirt from the carriage boards of mules), and allowing it at the same
time to yield and give way when any extraordinary pressure comes upon it,
and so to prevent damage to the machinery, as herein set forth, and described.

page_text: Second, I claim the construction, arrangement, and combination of the
parts of the mechanism shewn in Figs. 1, 2, 3, 4, and 5, to effect-the purposó
of enabling the scavenger roller to yield and give way when any extraordinary
pressure comes upon it, so as to prevent damage to the machinery (including
also the variations of the same), as set forth and described.
Third, I claim the application and adaptation of the mechanism shewn in
Fig. 6 to the purpose of cleansing and removing the waste and dirt from the
carriage boards of mules as herein set forth and described.
Fourth, and lastly, I claim the application, and adaptation of the mechanism
shewn in Figs. 7 and 8 to the combined purpose of cleansing and removing
'the dirt and waste from the carriage boards, and also the roller beams, and
stands of mules, as herein set forth and described.
In witness whereof, I, the said Eli Stott, have hereunto set my hand
and seal, this Eighteenth day of June, in the year of our Lord, One
thousand eight hundred and sixty-two.
