Improvements in Apparatus for Grinding Carding Engine Flats.
We, JOSEPH HILL of 300 Ainsworth Road, Manager, ROBERT ISHERWOOD of
294 Ainsworth Road, Carder, and JAMES ISHERWOOD of 9 Hall Street, Under-Carder,
all of Radcliffe near Manchester in the County of Lancaster, do hereby declare the
nature of our said invention to be as follows:-
Our invention relatos to improvements in apparatus for grinding the revolving flats
which are employed in carding engines in the form of endless chains, and has for its
object that of grinding the working face of the flats when sliding on the surfaces which
travel upon the curved guides or flexible bends of the carding engine. Above the
"taker-in" of the carding engine we mount the grinding roller in suitable bearings
on the carding engine framing. The flats are guided tangentially over the grinding
roller by means of guides attached to each side of the carding engine in any convenient
manner, being guided thereto by additional pulloys or rollers in line or otherwise
with the ordinary bottom guiding pulleys or rollers. This arrangement requires a few
more flats than under the old system. If desired this apparatus can be applied to any
other convenient part of the carding engine.

Improvements in Apparatus for Grinding Carding Engine Flats.
We, JOSEPH HILL of 300 Ainsworth Road, Manager, ROBERT ISHERWOOD of
294 Ainsworth Road, Carder, and JAMES ISHEKWOOD of 9 Hall Street, Under-Carder,
all of Radcliffe near Manchester in the County of Lancaster, do hereby declare the
nature of our said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Above
Our invention relates to improvements in apparatus for grinding the revolving flats
which are employed in carding engines in the form of endless chains, and has for its
object that of grinding the working face of the flats when sliding on the surfaces
which travel upon the curved guides or flexible bends of the carding engine.
the "taker-in" of the carding engine we mount the grinding roller in suitable
bearings on the carding engine framing. The flats are guided tangentially over the
grinding roller by means of guides attached to each side of the carding engine in any
convenient manner, being guided thereto by additional pulleys or rollers in line or
otherwise with the ordinary bottom guiding pulleys or rollers. This arrangement
requires a few more flats than under the old system. If desired, this apparatus can be
applied to any other convenient part of the carding engine.
Fig. 1 is a part side elevation of a carding engine with our improvements applied-
Fig. 2 is an end elevation of same- Fig. 3 is an enlarged side view of our invention-
Fig. 4 is an end view of same- Fig. 5 is a plan of Fig. 3, and Fig. 6 is an elevation
of the pulleys or rollers for guiding the carding engine flats over the grinding
roller.
To the side frames or bends A of the carding engine are fixed the adjustable
fixings B, on which is mounted the grinding roller in the bearings D. To the
fixings B are attached the bearings E and G, in which are mounted the shafts F
and H carrying the chain pulleys I and J. The endless chains K travel with the
revolving flats L in the direction indicated by the arrows as shown in Figs. 1
and 6. The principal object or aim of this invention is to grind the working
face of the revolving flats L with the face downwards, or in a similar position to
that when travelling on the side frames or bends A, the same being effected when
sliding on the bearing surfaces which travel on the curved ends M of the flexible
bends A of the carding engine. The flats L are guided tangentially over the
grinding roller C by means of the guides pivoted to the fixings B by the pins Q
attached to the side frames or bends A, the same being effected by the additional
pulleys I on the shaft F, which arrangement requires a few more flats than
hitherto as will be seen in Fig. 1. The guides 0-over which the flats travel in
their passage over the grinding roller Care provided with the arms P, which
are operated by the star wheels R mounted on the shaft F. As the star wheels R
revolve the teeth or projections T operate on the taper ends of the arms P and
oscillates the guides to allow of the wire faces of the revolving flats L being
uniformly ground to the inclination of their working surfaces, and if there should be any

page_text: irregularity of wear on the bearing surfaces S of the flats L on the bends A it
will not affect or interfere with the correctness of the inclination of the surface
of the wire on the flats when in their working position on the frames or bends A.
When the teeth or projections T on the wheels R operate against the taper ends
of the arms P, as in Fig. 7, the guides O are slightly raised, which is necessary
when the leading end of the wire surface of each flat is presented to the grinding
roller, and as the wheels R revolve the guides O are gradually lowered, as in Fig. 3,
to ensure the roller C grinding the said faces to the inclination of the filletting

roller can be driven by any well known mechanical means from any convenient
part of the carding engine.
When grinding has been performed the grinding roller is removed, and the
guides are raised to place the arms P out of contact with the star wheels R to
prevent unnecessary wear by means of the screws W mounted in the fixings B as in
Figs. 1, 3 and 4.
The advantage of this invention over others is that deflection is entirely removed
owing to the flats passing over the grinding roller on their own bearing surfaces, by
which all liability to strain is removed.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
0
In apparatus for grinding the flats of revolving flat carding engines while the said
flats are supported on their working or sliding surfaces, consisting of the oscillating
guides O pivoted to the fixings B, arms P, star wheels R, shaft F, and the chain
pulleys I, applied and operating substantially as described and as shown on the
drawings.
