We JOHN ALSTON HART of Cicely Bridge Mill Blackburn in the County of
Lancaster Mill Manager and DOCTOR CHARLES BAYNES of Kunzden House Black-
burn aforesaid Cotton Spinner and Manufacturer, do hereby declare the nature of
our said Invention for "IMPROVEMENTS IN THE CLASS OF CARDING ENGINES KNOWN
AS REVOLVING FLAT CARDING ENGINES to be as follows:-
"
Our Invention has for its object to overcome the difficulties arising from the
way or ways hitherto used for readjusting the relative positions of the carding
points of the flats to the carding points of the main cylinder. In place of making
the path upon which the bearing and travelling parts of the flats move adjustable,
I make each of the flats or its carding points capable of adjustment relatively to
its bearing and travelling parts so that the carding points of the flats are adjusted
to the opposed carding points of the main cylinder whereby the required adjust-
ment is readily effected and any necessity for adjusting the path upon which the
bearing and travelling parts of the flats move is obviated.

Agent for the above named John Alston Hart

We JOHN ALSTON HART of Higher Bank Blackburn in the County of Lancaster
Engineer and DOCTOR CHARLES BAYNES of Knugden House Blackburn aforesaid
Cotton Spinner and Manufacturer 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 has for its object to overcome the difficulties arising from the
way or ways hitherto used for adjusting the relative positions of the carding points
of the clothing on the flats to the carding points of the clothing on the main
cylinder. In place of making the paths upon and relatively to which the bearing
and travelling parts of the flats move or slide adjustable, I make each of the flats
with its carding points capable of adjustment relatively to its bearing and travelling
parts by the means hereinafter fully described so that the carding points on the
flats can be adjusted by means of screws with facility to the opposed carding points
on the main cylinder and as adjusted the parts of the flats are by the same screws
or their nuts firmly fixed in their adjusted position so that there is no objectionable
'vibration or movement of the parts as will be clearly understood by the following
description of the accompanying drawing Fig. 1 of which is a plan, Fig. 2 a
sectional elevation and Fig. 3 an end view of one end of a "flat" constructed
according to what we consider the best form of our Invention it being understood
'that each end is similarly constructed. We will for simplicity of description
however refer only to the one end shewn.
The part A is that which carries the card clothing B. The travelling part C
namely that which slides on the bend is formed with a surface similar to that
made on the ends of flats ordinarily used as the sliding surfaces of revolving flat
cards and is provided or formed with a screwed stem D which passes through a
hole in the part A these parts should fit each other accurately. There is a nut E
at one side of the part A and another nut F at the other side of the said part
between which huts when adjusted the end of the part A is firmly held The
surfaces of the part A and nuts E and F which are in contact should be faced
truly. By slacking off one of these nuts E or F and tightening up the other the
part A of the flat and the points carried thereby are adjusted so that the said
points are brought to their true working position relatively with the points on the
main cylinder and the said nuts pinch the end of the part A tightly between them
and hold it firmly. G is a bracket piece and guard formed or fixed on the part A
against which piece G a squared surface at c³ on the screwed stem abuts to steady
the parts and act as a guide to prevent the stem D from turning when the nuts are
rotated and also to prevent fibre being blown through the ends of the flats. H is
the pin for the operating chain of the flats, I is the surface used when grinding
the face of the flat clothing and J is the boss which gears with the star wheels for
driving the flat.

page_text: 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
First. An adjustable sliding flat for revolving flat carding engines in which the
part carrying the card clothing is adjustable with respect to the parts or shoes
which move along the "bends" by means of screws or screw nuts which screws or
screw nuts also constitute means for firmly pinching and securing the part or parts
as adjusted substantially as bereinbefore explained.
Second. In adjustable sliding "flats" for revolving flat carding engines the
part A carrying the card clothing provided at each end with a screwed post D
passing through the part A and formed in one with or rigidly fixed to the part C
which slides on the "bend" and the adjusting and fixing nuts E F substantially as
herein before described and illustrated in the accompanying drawing.
Third. The arrangement and combination of parts constituting an adjustable
sliding "flat" as herein before described and illustrated so far as one end of the
flat is concerned in the accompanying drawing.
