I, WILLIAM LAWTON, of Millgate, Paddock, Huddersfield, Yorkshire, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention has reference to the sliver box and to the sliver which falls therein
as it is being removed from the doffer by the ordinary doffing comb. In this
description of apparatus the sliver is carried away by means of an endless travelling
belt, and it often happens that the sliver catches in the corners of the box, thereby
damaging the said sliver.
The object of my invention is to keep the sliver in or about the centre of the
travelling sheet so as to prevent the said sliver from catching in the corners of the
sliver box.
In order to carry out my invention I preferably employ two vertical plates
supported and kept at a suitable distance apart by one or more cross bars. These
two vertical plates are placed into the sliver box and are connected by a rod to a
crank or to the side of a wheel or pulley, so that on rotary motion being given to the
said crank, wheel, or pulley, the said vertical plates receive an oscillatory motion at
right angles to the travelling sheet. If therefore the sliver is placed between the
oscillatory plates it is evident that such sliver will be kept about the middle of the
travelling sheet, consequently the sliver is not damaged as is now the case.
In addition to the oscillatory plates keeping the sliver in the middle of the travelling
sheet, the lower edges of the said plates which are in contact, or nearly in contact
with the travelling sheet, will scrape up loose fibres which would otherwise adhere to
the sheet, and keep it clean thereby.

Improvements in the Method of and Apparatus for Guiding the
Sliver in the Sliver Box Employed in Connection with Carding
Engines.
I, WILLIAM LAWTON, of Millgate, Paddock, Huddersfield, Yorkshire, Manufacturer,
do hereby declare the nature of this invention and in what manner the same is to be
peformed, to be particularly described and ascertained in and by the following
statement:
My invention has reference to the sliver box and to the sliver which falls therein
as it is being removed from the doffer by the ordinary doffing comb. In this
description of apparatus the sliver is carried away by means of an endless travelling
belt, and it often happens that the sliver catches in the corners of the box, thereby
breaking or damaging the said sliver.
The object of my invention is to keep the sliver in or about the centre of the
travelling sheet so as to prevent the said sliver from catching in the corners of the
sliver box.

To
In order that my invention may be better understood, reference is made to
the accompanying sheets of drawings illustrative thereof; wherein Fig. 1 is a
perspective view of one side of a carding engine having my improvements applied
thereto; Fig. 2 is end elevation with some of the parts in section, and Fig. 3 is
plan view.
a is the framework of the machine, the doffer, c the doffing comb,
actuated by vertical rod d from eccentric e. The sliver box is shown at f, in the
bottom of which the endless belt g travels in the direction of the arrow for the purpose
of carrying forward the sliver as it is beaten off the doffer b, such sliver passing
through the mouth piece 61 and between ordinary nipping rollers for conducting
the said sliver away, all of which parts are arranged in the ordinary manner.
carry out my improvements, I employ two plates and k arranged vertically in the
sliver box; the former is flexible and fastened to the inner side of the said box by a
bolt and the latter is free to oscillate upon the stud m. Theso vertical plates į
and k are caused to oscillate backward and forward within the box by means of
connecting rods n and o operated by eccentrics s and t driven by a cord from pulley u
or from any other convenient rotary part of the machine. It will be apparent that
as the sliver drops into the box f, the endless belt g will carry the said sliver forward
between the two vertical plates j and k; it will therefore be seen that the oscillatory
motion of such plates will keep the sliver about the middle of the travelling belt, and
therefore out of the corners of the sliver box and also clear of the sides of the said
belt, consequently, the sliver will neither be broken nor damaged, but will be kept
intact and a stronger yarn produced thereby.
In addition to tho oscillatory plates j and
the travelling belt, the lower edges of the said
keeping the sliver in the middle of
oscillatory plates (which are in contact

page_text: or nearly in contact with the upper surface of the said belt) will scrape up loose bits
of fibres which would otherwise adhere to the belt, whereby the said belt will be kept
clean.
In order to clean the nipping rollers h self-actingly, I place on the upper nipping
roller a bar to the underside of which carries a piece of felt or other suitable soft
material, whereby the surface of the upper roller is kept continuously clean; I also
fasten a piece of felt or other suitable material on to the top of the mouthpiece b',
one edge of which felt rests in contact with the nipping rollers for the purpose of
cleaning it.
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 I do not claim all the
parts described in the accompanying Specification and shewn in the drawings, but
what I claim is :
Firstly. The employment of oscillatory plates in combination with a travelling
belt for the purpose of keeping the sliver away from the edges of the said belt
substantially as described.
Secondly. The use of oscillatory plates in combination with a travelling belt,
working in a sliver box such as f for the purpose of keeping the sliver away from
the corners of the said box.
Thirdly. The means or method substantially as heroin shewn and described for
imparting motion to the oscillating plates j and k.
