PROVISIONAL SPECIFICATION.
Improved Apparatus to be Employed for Grinding the "Flats” of
Oarding Engines.
I JOSEPH JONES, Assistant Manager for Messieurs John Chadwick and Company
Limited of Tame Side Mil! Dukinfield in the County of Chester do hereby declare the
nature of this invention to be as follows:-
This invention relates to improved apparatus to be applied to carding engines for
the purpose of grinding the surface of the card teeth of the endless or travelling
"flats" of carding engines.
The invention consists principally of a fixing which is secured to the "horn-
bracket" and is slotted so as to allow another bracket to slide therein in a vertical
direction.
This last named sliding bracket carries at its upper end the journal of the emery
grinding roller.
It also carries an adjustable surface piece for compensating for the
bevil of the working surface of the iron "flat." This surface piece is adjustable in a
slot by means of a fixed screw with a lock nut so as to regulate the distance and thus
a constant distance.is maintained between the centre of the grinding roller shaft and
the surface of the wire under operation.
On the horn bracket I also fix an incline plate for lifting the "flat" to he
operated upon thereby dispensing with the weight and lever usnally employed for
this purpose.

COMPLETE SPECIFICATION.
Improved Apparatus to be Employed for Grinding the "Flats" of
Carding Engines.
I JOSEPH JONES, Assistant Manager for Messieurs John Chadwick and Company
Limited of Tame Side Mill Dukinfield in the County of Chester, 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 :-
This invention relates to improved apparatus to be applied to carding engines for
the purpose of grinding the surface of the card teeth of the endless or travelling
"flats" of carding engines.
The nature of ny said invention and the manner in which the same is to be per-
formed or carried into practical effect will be readily understood on reference to the
drawings hereunto annexed, and the following explanation thereof.
Fig. 1 is a face view and Fig. 2 an end view of the fixed part of the apparatus.
Figs. 3 and 4 are similar views of the sliding bracket and adjustable guiding plate
hereinafter referred to. Fig. 5 is an end view of the apparatus complete and Fig. 6
is a diagram showing the action of the apparatus upon the "flat," the latter being
shown in the position it assumes at the commencement of grinding.
To the ordinary horn bracket a (Figs. 1 and 2) I secure a fixing b which is slotted
or formed so as to allow another bracket c (Figs. 3 and 4) to slide therein in a vertical
direction. This sliding bracket c carries at its upper end e* the journal of the emery
grinding roller represented by the dotted arc d on Fig. 6.
It also carries an adjustable surface piece or guiding plate e to compensate for the
bevil of the working surface f of the iron "flat" g. This guiding plate e is formed
underneath with a step at ex (see Figs. 3 and 6) the surface upon one side of the said
רי

page_text: "
step not being parallel but at a slight angle to that upon the other side of the same so
as to present the surface of the wire to the grinding roller in such a way that as the
"flats
pass under the rolier, the necessary slight bevil is given to the face of the
wire as the working surface f of each "flat" moves over the stepped surface of
the guiding plate e.
This surface piece or guiding plate e is adjustable in the bracket e by means of a
fixed screw
provided with a lock nut i so as to regulate the distance and thus a
constant distance is maintained between the centre k (Fig. 6) of the grinding roller
shaft and the wire under operation.
On the horn bracket a I also fix an inclined or curved lifting plate (Figs. 2
and 6) for lifting the "flat" g up to the grinding roller to be operated upon thereby
dispensing with the weight, and lever usually employed, but if preferred the roller
may fall down to the "flat" or the weighted lever may be employed to raise
the flat.
Having now particularly described and ascertained the nature and object of my
said invention and in what manner the same is to be performed I declare that what I
claim is :-
The improved apparatus substantially as herein before described and illustrated by
the drawings annexed for grinding the "flats" of carding engines, and especially I
claim the particular construction and use of the surface piece or guiding plate
adjustable on the roller bracket for obtaining the necessary bevilling motion from the
working surface of the flat, whether used in combination with a fixed lifting bracket
or with a weighted lever.
