Improvements in and in Apparatus for Adjusting the Covers of
Certain Parts of Carding-engines.
We WILLIAM HALL RICHARDSON of Bank View, Derker, Oldham in the county of
Tancaster Machinist and WILLIAM GREAVES of 279 Park Road Oldham in the
county of Lancaster Foreman both in the employ of Messieurs Platt Brothers and
Company Limited of Oldham aforesaid Machinists, do hereby declare the nature of
this invention to be as follows:-
"
Our invention relates to carding-engines and consists in arrangements by means of
which we prevent cotton or other fibrous material from escaping from the "cylinder
of the carding-engine at the parts between the ends of the "flexible bend" and the
side framings of the carding-engine and which arrangements also enable the portions
of the cover of the carding engine which are situate between the "flats" and the
# doffer " and between the flats" and the "taker in" roller to be placed nearer to
the axis of the "main cylinder" as the "wire" upon the "main cylinder" becomes
shortened.
We support or secure each end of such portion of the cover of the "main cylinder"
of the carding-engine as is situate between the "flats" and the "doffer"
upon or to
the ends of a curved arm or curved arms formed upon a bracket or brackets which
may be slidden by means of a screw or screws upon a guide or guides secured to or
formed on one of the "bends" of the carding-engine. The curved arm or curved
arms above mentioned is or are formed so as to correspond as nearly as may be
necessary with the curvature of the "card surface" of the main cylinder of the
carding-engine. After the curved arm or curved arms has or have been adjusted
into position by means of the screw or screws above mentioned the bracket or brackets
to which such curved arm or curved arms is or are attached, is or are secured to the
"bend "
upon which it or they is or are mounted, by means of a screw or screws and
nut or nuts. By means of this portion of our invention we are enabled to adjust the
aforesaid portion of the cover of the "main cylinder" of the carding-engine nearer to
the axis of the "main cylinder" as the "wire" upon the surface of the "main
evlinder" becomes worn.

page_text: We support and adjust the portion of the cover of the "main cylinder" which is
situate between the flats" and the "taker in" roller by means of arrangements
similar in construction and use to those above described by means of which we
support and adjust the portion of the said cover which is between the "flats" and the
" doffer."
By the above described arrangements we are enabled to adjust the above mentioned
portions of the cover of the main cylinder" more closely and accurately to the
"wire" of such "main cylinder" than heretofore and also to keep the said portions
of the cover of the "main cylinder" in proper position relative to the surface of the
"wire
upon such "main cylinder" at all times during the wearing of such "wire."

Improvements in and in Apparatus for Adjusting the Covers of
Certain Parts of Carding-engines.
We WILLIAM HALL RICHARDSON of Bank View, Derker, Oldham in the County of
Lancaster Machinist and WILLIAM GREAVES of 279 Park Road Oldham in the County
of Lancaster Foreman both in the employ of Messieurs Platt Brothers and Company
Limited of Oldham aforesaid 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
"
Our Invention relates to carding-engines and consists in arrangements by means of
which we prevent cotton or other fibrous material from escaping from the cylinder
of the carding-engine at the parts between the ends of the "flexible bends" and the
side framings of the carding-engine and which arrangements also enable the portion

We support or secure each end of such portion of the cover of the "main cylinder
of the carding-engine as is situate between the "flats" and the "doffer
upon or to
the ends of a curved arm or curved arms formed upon a bracket or brackets which
may be slidden by means of a screw or screws upon a guide or guides secured to or
formed on one of the "bends" of the carding-engine. The curved arm or curved
arms above mentioned is or are formed so as to correspond as nearly as may bo
necessary with the curvature of the "card surface" of the "main cylinder" of the
carding-engine. After the curved arm or curved arms has or have been adjusted into
position by means of the screw or screws above mentioned the bracket or brackets
to which such curved arm or curved arms is or are attached is or are secured to the
"bend" upon which it or they is or are mounted by means of a screw or screws and
nut or nuts. By means of our invention we are enabled to adjust the aforesaid
portion of the cover of the "main cylinder" of the carding-engine nearer to the axis
of the "main cylinder as the "wire upon the surface of the "main cylinder'
becomes worn.
"
"
The accompanying drawing is a side view of so much of a carding-engine as is
requisite to illustrate our invention. a is one of the side-frames of the carding-
engine. Upon the side-frame a is mounted the bend to which is secured the
flexible bend" c. d is the "main cylinder" of the carding-engine.-The "card
surface" of the "wire upon the main cylinder d is indicated by the circle A-At the
"doffer end" of the carding-engine the flexible bend c terminates at C-Between
the end of the flexible bend c and the surface a¹ of the side-frame a we place a
curved arm e formed upon a bracket e¹. The bracket e' is provided with projecting
parts which are capable of being slidden upon ribs or guides formed upon the
bend b. Secured to the bend is a bolt provided with a nut g and washer gl. The
bolt passes through a slot h formed through the bracket e¹. Capable of being

page_text: screwed in the bracket e is a screw which screw j passes through and is free to be
turned in a hole formed in the flange 2 formed on the bend b. The screw j is
prevented from moving longitudinally by means of the head and a collar ³ secured
upon the screw j. The surface e² of the curved arm e is formed so as to correspond
as nearly as may be necessary with the curvature of the "card surface" of the main
cylinder d of the carding-engine.
Although we have above only referred to the curved arm e situate on one side of
the carding-engine we would have it understood that a similar curved arm is
required upon the opposite side of the carding-engine-The portion of the cover
of the main cylinder d of the carding-engine, situate between the "flats" and the
"doffer" is secured at one end to the surfaco e of the curved arm e, the other end
of the cover k being secured to the corresponding surface of the curved arm corre-
sponding to the curved arm e and situate at the other side of the carding-engine.
By the screw being turned in the required direction the portion k of the cover of
the main cylinder d of the carding-engine may be adjusted nearer to the axis of tho
main cylinder d as the "wire" upon the surface of the main cylinder d becomes worn.
By the above described arrangements we are enabled to adjust the above mentioned
portion of the cover of the "main cylinder" more closely and accurately to the
"wire" of such "main cylinder" than heretofore and also to keep the said portion of
the cover of the "main cylinder" in proper position relative to the surface of the
"wire "upon such "main cylinder" at all times during the wearing of such "wire."
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
Curved arms such as e each mounted upon one of the "bends" of a carding-engine
and constructed, arranged, mounted, used and operating substantially as herein before
described in reference to and indicated in and by the accompanying drawing and for
the purpose of supporting or carrying such portion of the cover of the "main
cylinder" of the carding-engine as is situate between the "flats" and the "doffer"
of the carding-engine.
