Year: 1870

page_text: LETTERS PATENT to Eli Stott, Machinist, Amos Ogden, Brass
Founder, and William Cookson Stafford, Foreman of Mechanics,
all of Ashton-under-Lyne, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF CLEARERS APPLI-
CABLE TO MACHINERY USED IN THE PREPARATION OF COTTON AND OTHER
FIBROUS MATERIALS."
Sealed the 26th July 1870, and dated the 11th February 1870.
PROVISIONAL SPECIFICATION left by the said Eli Stott, Amos
Ogden, and William Cookson Stafford at the Office of the Com-
missioners of Patents, with their Petition, on the 11th February
1870.
We, ELI STOTT, Machinist, AMOS OGDEN, Brass Founder, and
WILLIAM COOKSON STAFFORD, Foreman of Mechanics, all of Ashton-
under-Lyne, in the County of Lancaster, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF CLEARERS
APPLICABLE TO MACHINERY USED IN THE PREPARATION OF COTTON AND OTHER FIBROUS
MATERIALS," to be as follows:-
Our improved clearers are applicable to machines in which cotton,
linen, woollen, or other fibrous materials are worked or drawn by
means of rollers. Instead of the usual clearers we apply a compound

page_text: "
lever, which oscillates or turns on pivots which are supported by brackets
or springs attached to the stands or roller beam. This compound lever
is placed and operates beneath the rollers and is covered with cloth in
spaces corresponding to the fluted bosses of the rollers, and embraces
all or any of the rollers from back to front. The cloth is kept in contact
with the rollers by the action of the compound lever, the pressure of
which is regulated by a spring or springs, lever, or adjustable weight
placed on an arm or branch attached to the compound lever. Instead
of the cloth on the said lever (in cases where required) wo use rollers
either by themselves or as part of the said improved clearers. Also
instead of the compound lever we use as required simple levers arranged
to act in the same manner. The effect of this arrangement is that the
dirt and fly is effectually-retained and more casily removed, the com-
pound levers or simple levers adjusting themselves after the operation
of removing the fly or dirt.

page_text: and Isle of Man, an Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
CLEARERS APPLICABLE TO MACHINERY USED IN THE PREPARATION OF COTTON AND
OTHER FIBROUS MATERIALS," upon the condition (amongst others) that we,
the said Eli' Stott, Amos Ogden, and William Cookson Stafford, our
executors or administrators, by an instrument in writing under our, 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 we, the said Eli Stott, Amos Ogden, and
William Cookson Stafford, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following state-
ment, and the accompanying Sheet of Drawings, that is to say :-
Our Invention relates to machines in which cotton, linen, woollen, or
other fibrous materials are worked or drawn by means of rollers. Under-
neath the rollers it is usual and to a certain degree necessary to apply
what are called clearers for the purpose of arresting and retaining the
dirt and fly which are thrown out by the material during the process of
drawing through the rollers. If the dirt and fly were not collected and
retained as fast as produced portions of it would pass along with tho
material under process and finally become a serious damage and imper-
fection in the finished thread. The under clearers hitherto in use havo
the imperfection of being inconvenient and to a certain extent inefficient
for the purpose. Our improved clearers on the other hand perform in
the most efficient manner in collecting and retaining the dirt and fly
as fast as produced, and allow it to be removed with great facility and
readjust themselves immediately after the operation.
In order to make our Invention more clearly understood, we have
hereunto annexed a Sheet of Drawings, to which the following description
relates, and in which the same Figures and letters of reference indicate
24
the same parts.

Figure 1 shows a side or edge view of one of our improved clearers as
applied to a drawing, slubbing, or roving frame, and Figure-2-a-plan
of the same. A, A, A, section of the roller beam; B, B, stand for
carrying the rollers; C, C, C, C, four circles-representing sections of
the fluted bosses of the bottom rollers; D, D, D, D, the improved under

page_text: clearer, it is formed of metal and turns by means of adjustable sockets
(at E, E,) on adjustable pivots which are attached to the stand B, B, by
the same screw bolt which retains the slide of the stand in its place.
Ono of these adjustablo pivots is shewn at F, F; D1, D1, (Figure 2)
dotted lines on one half the clearer representing the clearer cloth,
shewing the manner in which it is carried over and under the cross
bars D2, D2, &c., by which it is held in contact with the bosses of the
fluted rollers C, C, C, C; G, G, stem attached to the frame of the clearer
by a screw bolt at G1. On this stem G slides the adjustable weight G2,
by which the proper amount of pressure of the clearer cloth on the fluted
bosses O, C, C, O, is regulated and adjusted. One of these clearers is
placed betwixt the stands all along the roller beam, there being as many
clearers as there are boxes of rollers. When the machine is at work the
clearer cloth gathers and retains the fly and dirt from the rollers. The
fly and dirt require to be removed occasionally from the clearer cloth.
This is effected by the attendant. who by depressing the clearer at the
front is enabled to introduce the hand for that purpose. On leaving hold
of the clearer it immediately readjusts itself by the action of the
adjustable weight G 2.
Figure 3 represents the plan of another of our improved clearers
similar to the one described, but which is somewhat varied in one or two
particulars, and Figure 4 represents a side or edge view of the same.
H‚H, H, H, framework of the improved clearer; H1, H1, dotted lines on
one half of the clearer representing the clearer cloth and shewing the
manner in which it is carried over and under the cross bars H2, II 2, by
which it is held in contact with the fluted bosses of the rollers; I, I, two
hooks by which the clearer is suspended from the back bar of the
machine (which carries the top slides); Il, section of the back bar, the
position of which is shown by dotted lines in Figure 3. The hooks I, I,
have each a vertical slot in them, and the framework H, H, has corre-
sponding horizontal slots, through these slots the screw bolts II 3, II 3,
pass, and thus by this means secure the hooks to the framework of the
clearer, and thus by this arrangement the back bar Il serves as a centre
on which the under clearer turns, whilst its proper position with respect
to the fluted bosses on the rollers is obtained by means of the slots and
the screw bolts H 3, H 3.

page_text: circumference of small rollers. To meet these cases we vary our. Inven-
tion in the following manner, as shewn in an edge or side view.in
Figure 5, and in plan in Figure 6:-K, K, K, three circles representing
sections of the fluted bosses of three rollers; L, L, L, three small rollers
covered with roller cloth, they turn on the pivots I, I, &c., which are
supported in recesses in the framework of the clearer M, M, M, &c...By
this arrangement the rollers L, L, L, are at liberty to revolve with their
covering of clearer cloth in contact with the fluted bosses of the rollers.
In other respects the construction, arrangement, and manner of using
this clearer is the same as those already described.
.
Another variation of our Invention is shewn in Figure 7. N, N, N,
framework of the clearer formed of metal. On this is placed and
attached with screws or otherwise a small board O, 0, 0, 0, this small
board is covered the clearer cloth, which when the clearer is in use
bears against the fluted bosses of the rollers.
In other respects the mode of suspending and using this variation
of our Invention is the same as those already described.
We have now described and shewn the best modes of making and
applying our Invention to the best of our experience and knowledge, but
we do not confine ourselves to the precise conformation and details of the
same as these require to be varied to suit the different machines to which
our Invention is applied.
It will have been observed that our Invention as described does not
require any alteration or variation in the construction of the machinery,
but instead of the appliances for supporting the centres or pivots on
which the clearers turn as described, it is obvious that brackets or
filbows attached to the roller beam may be made to answer the same
purpose, as is shewn in Figure 8, where P, P, represents a bracket or
filbow attached to the roller beam A, A, in which the centres or pivots
of the clearers can turn; but it is a construction which involves un-
necessary trouble and expense, and the use of which we do not therefore
recommend.
Having now described the nature of our Invention and the manner
in which the same is to be performed, it must be understood that we
do not confine ourselves to the precise details of arrangement and
construction as herein set forth as these may be varied as we have before
observed; but that what we do claim as new and of our Invention is as

page_text: . First. We claim the application, adaptation, and arrangement of
clearers, which are placed and operate beneath the rollers, which
clearers turn or vibrato on pivots or centres at the back of the roller
beam, the necessary pressure of the clearer cloth on the fluted bosses
being produced and regulated by means of an adjustable weight, as 5
shown in Figures 1, 2, 3, 4, 5, 6, and 7, and herein set forth and
described.
· Second. We claim the application and adaptation of the adjustable
socket E in combination with the adjustable pivot F, F, as shown in
Figures 1 and 2, and herein set forth and described.
Third. We claim the application, adaptation, and arrangement of the
adjustable hook I which turns on the back bar, as is shown in Figures 3,
4, 5, and 6, and herein set forth and described.

In witness whereof, we, the said Eli Stott, Amos Ogden, and
William Cookson Stafford, have hereunto set our hands and scals, 1
this Second day of August in the year of our Lord One thousand
cight hundred and seventy.
