Improvements in and relating to Carding Engines for Carding
Cotton, Wool, Silk, or other Fibrous Materials.
I, CHARLES ROBERTSHAW, of Westfield Mills, Mytholmroyd, in the County of
York, Cotton Spinner, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement; -
My invention relates to improvements in and connected with carding engines
for carding fibrous materials, this invention relates more particularly to cotton
carding engines.
The object of my invention is to provide a means for expeditiously piecing up
the broken ends of the sliver.
In order that my invention may be clearly understood I have reference to
the accompanying sheet of drawings in which like letters of reference indicate
like parts throughout the various figures therein shewn.
Figure 1 represents an elevation of my invention.
Figure 2 is a plan of Figure 1.
Figure 3 is a detail drawing shewing the sliver rollers.
a is a travelling band which is situate immediately in front and lengthwise
of the doffing cylinder E of the carding engine which is mounted on the rollers b
and 6 to which latter roller motion is imparted through the agency of the gear
wheel which wheel c is operated by the driving shaft d through the medium
of the trail of wheels as shewn in Figures 1 and 2. At the side of the carding
engine i.e. at the part where the sliver is to be side drawn and delivered from the
carding engine to the usual coiling apparatus (which is an important part of my
invention i.e., the relative positions of the doffer E and the rollers f and g) I
provide two vertically situated rollers ƒ and g between which the sliver is to be
drawn as hereafter mentioned, the said rollers are mounted on a box or frame h.
The roller fis provided with a bevil gear wheel i which gears into the correspond-
ing gear wheel on the shaft j. Upon the shaft m. I employ a spur gear wheel
on which shaft is also mounted gear wheel n. which gears with gear wheel o,
which latter gears with wheel c. The said shaft m is also provided with bevil
gear wheel s, see Figure 2, which gears with a corresponding bevil gear wheel t,
on the driving shaft d, which shaft d, is operated by a spur tooth wheel u operated
by any suitable driving or motion wheel the said wheel may be placed in and out
of gear with s by suitably sliding same with wheel u on shaft d thus motion is
imparted from the driving shaft d to the train of wheels just described, the
wheel operating the wheel & consequently the vertical roller f. The wheel o
operating the wheel e consequently the travelling band a. At the lower side of
the roller f. next to the bevil wheel, I also provide a small spur gear wheel 22
which gears into a corresponding gear wheel at the lower part of roller 9 con-
sequently the two rollers f and 9 are geared together. The surface of roller 9 is
in close contact with the roller f which roller is allowed and free to swivel on

page_text: the stud at the lower part of the said roller. The said roller being also provided
with a lever or arm with which is connected a spiral spring IC supported on a
rody carried by the box or frame h consequently the said surface of the
roller g
is capable of a slight movement from the surface of the roller f but is
caused to remain and is maintained in close contact therewith by said spring,
the said roller is caused to rotate on its spindle z by the gearing before
described which roller g forms a sensitive motion surface for the drawing of the
sliver between the nip of the rollers. Immediately in front of the rollers i.e. at
the part opposite or near to the travelling band a I employ a guide piece or
plate A having an eye or opening B, and which is situate immediately opposite
to the nip of the rollers f and g which guides the sliver to and between the said
rollers. The eye B is formed in two parts B & B the portion B is formed on
a swivel piece or plate which swivels or turns about stud C₁ which piece C when
in its working position is as shewn in dotted lines Fig. 3 and so maintained by its
contact with the stop piece C. I provide in contact with the surfaces of the
rollers f and clearer pieces or strips of wood F and F which bear against the
surfaces of the said rollers.
The operation of this invention is as follows, as the carded material is stripped
from the doffer E, of a carding engine on to the travelling band a and passing
thereon, in the form of a web, the said web is then passed through the eye B of
the plate A thus forming a sliver thence between the rollers f & g to the coiling
apparatus in the usual and well known manner. The rotary action of the rollers f
and g delivering the sliver on to the said apparatus the material thus being
side drawn from the doffer.
In the event of the breaking of an end or sliver the swivel piece C is raised
and the end of the sliver readily placed in the eye or part B or the said end may
be slid or placed between the rollers ƒ and g vertically as the roller f readily
gives, due to any slight pressure consequently the travelling sliver impelled or
carried forward by the band a may be readily placed between the rollers f
obviating the tedious operation of threading through an eye; obviating breakage
of or damage to the sliver or the accumulation of material in front of the face
plate A or at the said rollers which may be due to obstructions or delay in
threading. In the event of breakage of the material the same passes down into
the space D between the end of the travelling band a, and the box or frame h.
The clearer pieces F and F are provided in order to clear and free the surfaces
of the rollers and g from fluff, consequently to maintain the same in working
condition.
The arrangement of the vertically situated rollers relatively to the doffer E
greatly facilitates the threading or insertion of the broken ends, also obviates
damage or breakage of the material, due to the dragging action across an inclined
plate or piece as is now used. The material according to this arrangement is fed
to the rollers by the band a, which material may be inserted between the nip of
the vertical rollers, which vertical position is important facilitating the easy
introduction or insertion of the end of the sliver by the attendant between the
same and the clearance of all fluff by the clearers F and F which are respec-
tively pressed against the rollers f and g by the spring pieces G and G¹ the
whole of which combination now just described ensures great economy in work-
ing, such as minimising loss due to broken ends and expediting the process of
the insertion of the sliver between the rollers aforesaid.
Having now particularly described 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:-
1. In combination travelling band a, the rotary actuating rollers f and g the
clearer pieces F and F, the eye plate A in which combination the rollers are
vertically situate in the position as shewn relatively to the doffer E substantially 5

page_text: as and for the purposes herein before set forth and described in the drawings
hereunto annexed.
2. In combination the rollers f and g the plate A, the clearer pieces F. F and
the springs G G substantially as and for the purposes hereinbefore set forth
and described in the drawings hereunto annexed.
3. In combination the rollers ƒ and g clearer pieces F F and springs G G¹
substantially as and for the purposes hereinbefore set forth and described in the
drawings hereunto annexed.
4. The rollers and g situated relatively to the doffer E where by the sliver
is side drawn by a pair of verticaly rotating rollers as and for the purposes herein
set forth.
