IMPROVEMENTS IN CARDING MACHINERY
Year: 1884

page_text: I FRANCIS EDWIN ROBINSON of Millgarth Mills, Leeds in the County of York
do hereby declare the nature of said invention for "IMPROVEMENTS IN CARDING
MACHINERY" to be as follows:-
My improvements have reference to machines for "carding" wool and other
fibrous substances. Hitherto cylindrical "doffers" have been used between and in
front of the "swifts" of such machines. At the point where the swifts and doffers
meet there is very little carding surface in contact at one time. Now in my
improvements instead of the cylindrical doffers I employ travelling sheet doffers
mounted on rollers through which traverse motion is transmitted thereto.
By this arrangement I am enabled to provide a much larger carding surface
between the swifts and sheet doffers thereby greatly increasing the working
capacity of the machine.
.
In my arrangement also when required I am enabled to employ more "stripper"
and "worker" rollers than hitherto, thus further increasing the advantages of my
improvements.

page_text: I FRANCIS EDWIN ROBINSON of Millgarth Mills Leeds in the county of York
do hereby-declare the nature of my said Invention for IMPROVEMENTS IN CARDING
MACHINERY and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
.
My improvements have reference to machines for carding wool and other fibrous
substances. Hitherto cylindrical "doffers" have been used between and at back of
the swifts of such machines At the point where the swifts and doffers meet there
is very little carding surface presented at one time. Now in my improvements
instead of the cylindrical doffers, I employ travelling sheet doffers mounted on
rollers through which traverse motion is transmitted thereto. By this arrangement
I am enabled to provide a much larger carding surface between the swifts and
sheet doffers therebý greatly increasing the working capacity of the machine.
In my arrangement also when required I am enabled to employ more "stripper"
and "worker" rollers than hitherto thus further increasing the advantages of my
improvements.
And in order that my Invention may be more completely understood reference
is given to the accompanying drawings and to the letters and marks thereon.
Fig 1 is a side elevation. Fig 2 a plan shewing my improvement applied to
carding engines. Other parts of the machine not shewn in drawings or discribed
hereafter are of the ordinary well known construction. Hitherto in the con-
struction of carding engines, it has been customary to employ cylindrical doffers,
that is to say doffers of a cylindrical form clothed or covered with carding, these
have been employed between and at back of the swifts At the point where the
swifts and cylindrical doffers meet there is very little carding surface presented at
one time.
+
Now in my Improvements I employ endless card sheets such as are shewn
at a, b, c and d. When arranged as shewn at a, the endless card sheeting passes
over two cylinders e, and feither or both of such cylinders may be adjustable in
their hearings, so as to be enabled to adjust the card sheeting to the swift g.
When arranged as shewn at b, the endless card sheeting passes over four rollers or
cylinders each being adjustable in sliding bearings so as to regulate the distance
between such carding b and the swifts h and i. A weighted roller ; may be
employed as shewn to impart the required degree of tightness to the card sheet.
Now when the endless card sheeting is applied as shewn at c and d, it is in each
case passed over three cylinders or rollers k, lm, and n, o and p; any or all of these
rollers may also be made ajustable in their bearings in the manner usually
employed on carding engines.
•
It will clearly be seen that by the above arrangement of carding sheet doffers a
very much increased carding surface is obtained between the swifts and the endless
sheet doffers than when cylindrical doffers are employed resulting in a greater
amount of work being done and at the same time of a much better quality and
much less waste.
w are what are known as angle strippers for stripping the carding material from
the endless doffer sheets and placing it on the swift cylinders; are ordinary
fancies for raising the material on the swift cylinder ready to be taken off by
endless sheet doffer as such swift cylinder revolves. y is a fancy for raising the
fibre on endless sheet doffer 6 before such doffer b brings it in contact with the
swift i.
The direction in which the various parts rotate or move are shewn by arrows.

page_text: The sheet doffers c and d are for stripping the carded material from the
cylinder i and conveying away, but in woolen material it is conveyed in threads to
the rubber sheets.
Having now particularly discribed and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
-
In carding engines the employment of endless card sheets instead of ordinary
cylindrical doffers for the purpose of increasing the carding surface substantially as
herein set forth and shewn in the accompanying drawings.
