I, JONAS HALEY, of Pyenot Mills, Cleckheaton, in the County of York, Card
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for surface grinding the cards on flats of
flat carding engines, and is designed to grind an entire set of flats or a consider-
able number of such at one operation.
According to this invention two triangular or three sided frames are set at
a distance apart equal to the length of the flats, the frames have each a groove
in which the ends of the flats are received and the corners of the frame are
semicircular. The flats are introduced to the grooves by first placing one end
in the groove of one frame and then canting the opposite end of the flat until
it will pass into its groove in the other frame, and the flat is then moved down
the inclined side of the frames to near their semicircular corners and there the
ends of the flat are received between the teeth of two star wheels on opposite
sides of the framing carried on a cross shaft, and as the several flats are so placed
in the groove and carried forward by the star wheels, they are passed or pushed
forward one against the other into the groove formed along the bottom or hori-
zontal part of the frame, where they accumulate side by side, the cards or
wire" downwards, and subjected to the action of grinding rollers and the
accumulating flats will be pressed round the corner into the vertical or upright
part of the framing, and as the frames are nearly filled with flats the latter
are driven or forced round the framing by the star wheels until long enough
circulated and exposed to the action of the grinding rollers, as the flats arrive
near the upper part of the grooves in the upright parts of the frames they are
received by star wheels and carried round the corners of the frames to the
inclined portion of the same again.
Four grinding rollers are a convenient number for operating on a set of flats,
said rollers being driven from two pulleys, each operating two driving straps
passing over elongated small pulleys or bosses on the axles of the grinding
rollers, and endwise traversing motion is given to the emery rollers by means
of worm, worm wheel, eccentric, and a forked clip hinged to a stud.
Convenient mechanism for driving the going parts of the machine comprise
a main shaft and fast and loose pulley. On the shaft is a worm driving a
wheel on a vertical shaft, the upper end of which carries a worm gearing with
a wheel in the upper star wheel shaft, a chain from the latter drives the lower
star wheel shaft.
For adjusting the grinding rollers vertically to the wire on the flats to be
ground, the axles of said rollers are carried in slide pieces or necks connected
to strap eccentrics which soon as adjustment of the rollers is effected, are fixed,
and in order to hold each flat steady and in true relative position in its grooves
whilst the grinding roller is operating, there is provided a presser pulley over
each grinding roller so that as the flats in succession arrive at the several grinding
rollers they each pass under the presser pulley and are thus steadied in true

page_text: relative position to the grooves and to the grinding rollers, said presser rollers
being carried on end of a short lever or spring so as to yield slightly on the
flat coming under the pulley.
A wire cleaning brush is applied at one end of the frames for cleaning and
polishing the card wire on the flats.

Improvements in Machines for Grinding the Wire on Card Flats.
I, JONAS HALEY, of Pyenot Mills, Cleckheaton, in the County of York, Card
Maker, 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 machines for surface grinding the cards on flats of
flat carding engines and is designed to grind an entire set of flats or a consider-
able number of such at one operation.
The invention consists of a machine tool or appliance in which the card
covered flats are placed, and the appliance automatically corrects and adjusts
the positions of such flats and passes them over a series of grinding rollers to
which a to and fro endwise motion is imparted in addition to the revolving
motion. The revolving of the grinding rollers grinds the dents or teeth on
the flats and the endwise to and fro motion prevents the grinding rollers
becoming unduly worn in any one place and obviates the formation of furrows
or inequalities.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings,
in which
Fig. 1 is a side elevation of the improved tool or appliance for purpose
aforesaid.
Fig. 2 is a sectional side elevation of the improved tool or appliance.
Fig. 3 is an end view of the apparatus for imparting the endwise to and
fro motion to the grinding rollers.
Fig. 4 is a side elevation of the interior of Fig. 3.
According to this invention the improved appliance comprises two triangular
or three sided frames 1, 1 set at a distance apart equal to the length of the
flats, the frames form parts of the side frame of the machine and have each
a groove 2 in which the ends of the flats 3,3 are received and the corners 4, t
of the frames 1, 1 are semi-circular. The flats 3,3 are introduced to the
grooves 2 by first placing one end in the groove 2 of one frame
and then canting the opposite end of the flat until it will pass
into its groove 2 in the other frame, and the flat 3 is then moved
down the inclined side of the frames 1, 1* to near their semicircular corners 4.4
at the lower end of the incline, i.e. at the right hand side of the drawing Fig. 2,
and there the ends of the flats 3,3 are received in or between the teeth of two
star wheels 5 on opposite sides of the framing of the machine and carried on
a cross shaft 6, and as the several flats 3,3 are so placed in the grooves and
canied forward by the star wheels 5,5 they are passed or pushed forward one
against the other into the groove formed along the bottom or horizontal part I
of the frame 1, 1' where they accumulate side by side, the cards or
wire
"

page_text: dents or teeth downwards, and here they are subjected to the action of grinding
rollers 8, S and the accumulated flats 3, 3 will be pressed forward to and carrieu
round the corner 4 by the star wheel into the vertical or upright part 10
of the framing 1, 1 and as the frames 1, 1 are filled or nearly filled with
flats 3,3 the latter are driven or forced round the framing 1, 1 by the star
wheels 5,5 until long enough circulated and exposed to the action of the grinding
rollers 8, 8.
Four grinding rollers 8, 8 are a convenient number for operating on a set
of flats 3, 3, said rollers 8, 8 being driven from two pulleys 11, 11 operating two
driving straps 12, 12 passing over elongated small pulleys or bosses 13, 13 on
the axles 14 of the grinding rollers 8, 8 and endwise traversing motion is given
to each emery roller 8, 8 by means of a worm 15 secured to the roller shafts 14,
the worm 15 is surrounded by a case or box 16 and contains a toothed wheel 17
which gears with the worm 15. On the axle 18 of the toothed wheel 17 is an
eccentric pin 18' which is connected to a fork 19 and the other end of said
fork 19 is hinged to a stud 20 fixed to the frame of the machine. As the
grinding ollers 8, 8 and shafts 14, 14 revolve a rotary motion is imparted to
the toothed wheel 17 by means of the worm 15 and the hinged fork 19 and
eccentric pin 18 cause the shaft to travel or slide endwise or to and fro in its
bearings.
Convenient mechanism for driving the going parts of the machine comprise
a main shaft 21 and fast and loose pulley. On the shaft 21 is a worm *)*)
driving a wheel 23 on a vertical shaft 24 the upper end of which carries a
worm 25 gearing with a wheeel 26 on the star wheel shaft 6, a chain 27 from
the latter drives the other star wheel shaft 6.
For adjusting the grinding rollers 8, 8 vertically to the wire on the flats 3, 3
to be ground, the axles 14, 14 of said rollers 8,8 are carried in slide pieces or
necks 30, 30 connected to strap eccentrics 31 which soon as adjustment of the
rollers 8, 8 is effected are fixed, and in order to hold each flat steady and
in true relative position in its grooves 2,2 whilst the grinding rollers 8.8 are
operating there is provided a presser roller or bowl 32 over each grinding
roller 8 so that as the flats 3,3 in succession arrive at the several grinding
rollers they each pass under the presser roller 32 and are thus steadied in true
relative position to the grooves and to the grinding rollers 8, 8, said presser
rollers being carried on the end of a short lever or spring 33 so as to yield
slightly on the flat 3 coming under the pulley (see Fig. 1).
Instead of such presser rollers 32 a spring piesser bar 34 (see Fig. 2) may
be mounted over the flats 33 as shewn. A presser roller 32 is fixed above the
star wheel so as to keep the flat 3 steady when in contact with the wire
cleaning brush 35 which is applied for cleaning and polishing the card wire on
the flats. Instead of the wire brush 35 an additional grinding roller may be
applied if desired that the teeth or dents be "side ground" and side grinding
roller would consist of a series of V shaped or angular discs of emery placed
side by side on the shaft 36.
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: -
(1). The general construction, arrangement, and combination of parts consti-
tuting the improved machine tool as and for the purpose herein described and
substantially as illustrated by Fig. 1 and 2 of the accompanying drawings.
