Improvements in and in connection with the Feed Rollers of
Machines used in the Preparation of Cotton and other Textile
Materials.
I THOMAS RODGERSON MARSDEN of 3 Barlow Street, Oldham, Foreman, in
the employ of Messrs. Platt Brothers & Company Limited, of Oldham, Machinists,
do hereby declare the nature of this invention to be as follows:-
My invention relates to the "feed rollers" which are used to pass forward
cotton or other textile material which is to be opened or beaten or otherwise
operated upon.
Such rollers are fluted or grooved from end to end excluding the journals as is
well understood. In the working of such rollers there is a tendency at times for
the material being operated upon to collect upon or to coil around the rollers
or one of them this defect being well known under the designation of "roller
lapping."
I have reason to believe that this roller lapping is to a great extent caused
by the accumulation of fluff in the grooves at the extreme ends of the rollers.
To prevent such accumulation the roller ends have been turned down to or a
little below the bottoms of the grooves but this has not prevented roller lapping.
According to my invention I flute only the part of each roller which directly
acts upon the cotton leaving the extreme ends plain and of the same diameter as
the intermediate part of the roller or by preference slightly larger in diameter so
that when the rollers are "running empty" the ridges between the flutes will clear
each other and the rollers will not hammer or rattle or not to the usual extent.
The flutes or grooves may be cut in the roller by means of a milling machine or by
suitable means.
The plain
or unfluted ends upon the rollers may be obtained by turning off the
or ridges at each end of the roller and by shrinking or fixing upon the
turned down ends metal hoops of the required diameter.
"teeth
I prefer to undercut the ends of the said teeth or ridges and to cone the ends of
the hoops. In any case I might make the cylindrical ends of the rollers slightly
less in diameter than the fluted part.
Instead of the hoop or ring used to fill up the part of the feed rollers turned
away I sometimes extend a shroud from the bracket which carries the feed roller
so that it fills up the space hitherto filled by the teeth and flutes of the feed roller
forming in fact a stationary ring or hoop.

I THOMAS RODGERSON MARSDEN of 3 Barlow Street, Oldham, Foreman, in.
the employ of Messrs. Platt Brothers & Company Limited, of Oldham, Machinists,
do hereby declare the nature of this 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:-

page_text: cotton or other textile material which is to be opened or beaten or otherwise
operated upon.
Such rollers are fluted or grooved from end to end excluding the journals as is
well understood.
In the working of such rollers there is a tendency at times for the material being
operated upon to collect upon or to coil around the rollers or one of them this
defect being well known under the designation of "roller lapping."
I have reason to believe that this roller lapping is to a great extent caused
by the accumulation of fluff in the grooves at the extreme ends of the rollers.
To prevent such accumulation the roller ends have been turned down to or
a little below the bottoms of the grooves but this has not prevented roller
lapping.
According to my invention I flute only the part of each roller which directly
acts upon the cotton leaving the extreme ends plain and of the same diameter as
the intermediate part of the roller or by preference slightly larger in diameter so
that when the rollers are "running empty "the ridges between the flutes will
clear each other and the rollers will not "hammer" or rattle or not to the usual
extent.
The plain or unfluted ends upon the rollers may be obtained by turning off the
" teeth" or ridges at each end of the roller and by shrinking or fixing upon the
turned down ends metal hoops of the required diameter.
The nature of my invention and the manner in which I carry the same into
practical effect will be clearly understood when reference is had to the accom-
panying drawings.
In the said drawings.
Figs. 1 and 3 illustrate the application of my invention to a cotton opener.
Figs. 2 and 4 illustrating the application to a scutcher.
In Fig. 1A A are the feed rollers which feed the cotton to the beaters of the
opener as is well understood. In Fig. 3 a is the journal at one end of the upper
feed roller. Between this journal and the fluted part A of the roller is a plain
cylindrical part or collar a' which is slightly larger in diameter than the tops of
the flutes. Both of the rollers are formed or provided at each end with a
cylindrical part or collar such as a' and it will be apparent that when the rollers
are running empty-that is to say when cotton is not being passed forward to the
beater the collars of the upper roller will roll upon the collars of the lower
roller and the ridges between the flutes or grooves will clear each other as
aforesaid.
It will be seen that the collar a' extends some distance within the casing-
indicated by e-so that the junction at d between the flutes and the collar is well
within the range of action of the outside beaters b. The two collars may be
formed in one piece with the roller the flutes being cut by a milling machine so as
to die out at the line d or being cut by other suitable means which will give the
same result.
For convenience of construction however I flute the rollers in the ordinary
manner and subsequently turn down the ends of the roller to receive rings which
are shrunk or tightly forced on the roller ends and constitute the collars a¹. Fig. 5
illustrates this construction. A square corner at the end of each flute is avoided
by undercutting the ends of the ridges and by turning one end of the ring a¹ to a
conical form to correspond as clearly appears in the drawing.
I do not confine myself in respect of making the collars a slightly larger in
diameter than the fluted part of the roller and if preferred such collars might be
flush with the tops of the ridges or even a little below them-that is to say the
collars might be a little less in diameter than the fluted part of the roller.
In Figs. 2 and 4 the collar a¹ is represented as being a little less in diameter than
the extreme diameter of the grooved part of the roller.
In these figs. the beater is represented by e and the beater shaft by f these being
ordinary parts of the machine.

page_text: Although my invention is illustrated in its application to cotton machinery this
being its principal and most important application it must be understood that I may
apply my invention to the grooved feed rollers of machines used in the preparation
of other fibrous materials.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1) The grooved feed rollers having grooves or flutes extending between the
points d near the roller ends parts a¹ at each end being left without grooves as and
for the purpose set forth.
2) The grooved feed roller turned to receive a collar a' at each end such collar
being slightly larger in diameter than the extreme diameter of the grooved part of
the roller as and for the purpose set forth.
3) The grooved feed roller provided at each end with a collar a¹ of the pro-
portions and applied or secured as set forth.
