PROVISIONAL SPECIFICATION.
Improvements in Grinding the Flats of Carding Engines.
I, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited, of
Oldham in the County of Lancaster, Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to revolving flat carding engines and the object of my
invention is to grind each flat accurately from its prepared surface which travels
upon the flexible bend or equivalent when the engine is in work.
In carrying my invention into effect I reverse the flat to be ground in any
convenient manner and support it upon suitable movable or stationary brackets;
the bearings of the grinding roller are mounted in slideways in or on the usual
roller brackets and are raised or lowered according to the thickness of the flat.
passing under them. Brackets secured to the roller bearings have a prepared
surface which rests upon the prepared working surface of each flat when it is being
ground and the brackets are carried forward by each flat as it travels under the
grinding roller and is then released by an inclined surface on the grinding bracket
and drawn back by a spring or weight to meet the next flat and at the same time
adjust the vertical position of the grinding roller from the working surface of the
said flat.
By this arrangement a definite distance is constantly maintained between the
working surface of the flats and the bearings of the grinding roller and it follows
that the wire or clothing of each flat will be ground to one uniform extent.
In place of the mechanism described for releasing the brackets that rest upon
the prepared surface of the flat being ground other means may be employed such
as a lever operated from any one of the flats.

COMPLETE SPECIFICATION.
Improvements in Grinding the Flats of Carding Engines.
I, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited,
of Oldham in the County of Lancaster, Engineer, 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:-
My invention relates to revolving flat carding engines and the object of my
invention is to grind each flat accurately from its prepared surface which travels
upon the flexible bend or equivalent when the engine is in work.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a side view and Figure 2 a front view of part of a carding engine to
which my improvements are applied.
It will be understood that certain parts of the mechanism are employed on both
sides of the engine, although only one side is shown.
In the drawings, a designates the bend or side framing of the carding engine,
the flexible bend on which the flats travel, c the bracket for carrying the grinding
roller 9, and d, d, are two flats shown with their wire surface upward which is the
position they occupy whilst being ground.

page_text: The grinding roller bracket c carries a stud c¹ on which is pivoted a bracket e
with slideways for the bearing f of the grinding roller g, the position of which with
regard to the bracket e is adjustable by means of the regulating screw h which
passes through a projection on the bearing f and is screwed into a boss e¹ on the
bracket e. The bearing f is secured to the bracket e by a bolt which passes
through a slot in the bracket e, and at each end of said bracket is a box or recessed
space ee into which is fitted a slide bar i which has a prepared surface i¹ stepped
at to one end of the bar i is connected by a chain k a weighted lever k which
is fulcrumed at k³.
To the roller bracket c is secured a guide rail ; provided with two inclined
surfaces and a prepared surface between the two; as the flats approach the
grinding roller g their surfaces d¹ travel along the incline j¹, until the prepared
surface d of the flat-that is the portion which when in work travels over the
flexible bend approaches the prepared surface i¹ of the bar i; at this time the snug d
of the flat travels upon the prepared surface and the surfaces d and i will be in
contact, consequently through the intervention of the flat the bracket j now supports
the bracket e, bar i and grinding roller g and the movement of all these parts is
governed by the prepared surface d³ of the flat; the front edge of which acting
against the stepped portion of carries the bar i forward with it until the flat
has passed beyond the grinding roller g and been ground when its snug a drops
from the surface j³ on to the incline thereby releasing the bar i and allowing the
weight to draw it back until a stop comes against the side of the box e of the
bracket e and remains in such position until the next flat engages the projection ³.
By this arrangement a definite distance is constantly maintained between the
working surface of the flats and the bearings of the grinding roller and it follows
that the wire or clothing of each flat will be ground to one uniform extent.
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 :-
In a travelling flat carding engine-
1. Combining the bearings of the grinding roller with a slide bar or bracket on
which is formed the guiding surface against which each flat beds whilst being
ground, and supporting the weight of the combined grinding roller and slide bar
by the said flat the back of which travels upon a stationary prepared surface all
substantially as herein set forth.
2. The combination and general arrangement of the parts substantially as herein
shown and described for the purpose specified.
