"IMPROVEMENTS IN APPARATUS FOR HEATING HARDENING AND TEMPERING STEEL
WIRE USED IN THE MANUFACTURE OF CARDS, AND IN APPARATUS EMPLOYED IN
THE GRINDING AND POINTING CARDS
This Invention relates
"
Firstly To improved apparatus wherein electricity is employed for heating and
tempering steel wire used in the manufacture of card teeth
Secondly-To improved apparatus for grinding and pointing the teeth of cards
The wire to be heated is caused to pass (by preference) under two bars or rods
of brass copper or other conductors such bars or rods being connected by wires
with a dynamo machine so that a current of electricity sufficient to beat the wire
is provided, and in order to maintain uniformity of degree of heat we employ a
secondary battery or accumulator, as the wire is drawn forwards and acquires the
necessary heat it thence passes into a hardening bath of oil water or other
hardening medium after leaving which it is again submitted to heat obtained from
Povice 1021

page_text: electric current or other source of heat so as to temper or reduce the degree of
hardness-The heating being effected from the source referred to "electricity" the
wire is not subjected to the injurious action of sulphur as where the heatings from
combustion of coal coke, or coal gas-and uniformity of heat and equality of
temper of wire is secured.
The card grinding and pointing apparatus comprises discs of emery having steps
projections or recesses formed either "in and in" or opposite each other on or in
the faces thereof. The steps, projections or recesses are formed by radial curved or
waved lines and which may taper or feather out near the greater circumference
of the disc, and in some cases the surface of the discs are corrugated-The emery
discs as aforesaid are secured concentric, or eccentric, to the axis or shaft on which
they are mounted and by which they are caused to rotate
The discs as described may be used separately, in sections or numbers equal to
the width of a card under operation so as to grind and point any width of card
equal to or less than the width of a card cylinder, in the latter case one or more
sections are removed from the shaft
A square shaft or a shaft having key groove cut therein is employed for rotating
and traversing the sections of emery discs

"IMPROVEMENTS IN APPARATUS FOR HEATING HARDENING AND TEMPERING STEEL
WIRE USED IN THE MANUFACTURE OF CARDS, AND IN APPARATUS EMPLOYED IN
THE GRINDING AND POINTING CARDS
This invention relates to :
"
Firstly To improved apparatus wherein electricity is employed for heating and
tempering steel wire used in the Manufacture of card teeth.
Secondly To improved apparatus for grinding and pointing the teeth of cards.
The wire to be heated is caused to pass (hy preference) under two bars or rods
of brass copper or other conductors of electricity such bars or rods being connected
by wires with a dynamo Machine or other source of electricity so that a current of
electricity sufficient to heat the wire is provided, and in order to maintain
uniformity of degree of heat we employ a secondary battery or accumulator such as
Plante's. As the wire is drawn forwards and acquires the necessary heat it thence
passes into a hardening bath of oil water or other hardening medium after leaving
which it is again submitted to heat obtained from electric current or other source
of heat so as to temper or reduce the degree of hardness-The heating being
effected from the source referred to "electricity" the wire is not subjected to heat.
the injurious action of sulphur as where the heating is from combustion of coal,
coke, or coal gas and uniformity of heat and equality of temper of wire are
secured.
The card grinding and pointing apparatus comprises discs of emery having steps,
proje-tions and recesses formed either "in and in" or opposite each other on or in
the faces thereof. The stops projections, or recesses are formed by radial curved
corrugated or waved lines--and which may taper or feather out near the greater
circumference of the disc, and in some cases the surface of the discs is corrugated.
The emery discs as aforesaid are secured concentric to the axis or shaft on which
they are mounted and by which they are caused to rotate.
The discs as described may be used separately in sections or in numbers equal to
the width of a card under operation so as to grind and point any width of card
equal to or less than the width of a card cylinder, in the latter case one or more
sections are removed from the shaft. A square shaft or a shaft having key groove
cut therein is employed for rotating the Sections of emery discs.
Such being the nature and object of this our said invention we will now proceed
to describe the same in detail and in order that the invention may be fully
understood we have hereunto annexed 5 sheets of drawings illustrating the
construction and use of the invention.

page_text: Fig. 3 is an end elevation of apparatus for grinding and pointing the teeth of
cards.
Fig. 4 is a front elevation of Fig. 3.
Figs. 5 to 12-inclusive are enlarged views of improved discs of emery for
grinding.
Referring now to Figs 1 and 2 at 1. 1. 1 is the wire to be heated hardened and
tempered, in the process the wire is caused to pass between the pins 2 under the
bars or rods of brass (copper or other conductor of electricity) 3-At 4 is a dynamo
Machine such as Wilde's, Gramme's, or Crompton's or other source of Electricity
the wires 5. 6 from which are connected to the secondary battery or accumulator 7
such as Plante's or Faure's whereby the current of electricity produced is regulated
and from 7 continued to the rods 3. 3-At 8 is a cistern containing oil water or
other medium being fed from the overhead supply tink 9-At 10 is an appliance
composed of flannel cotton waste or other absorbent through which the wire is
passed so as to remove therefrom oil water or other medium employed in the
hardening the wire before passing to the second pair of rods or bars 11. 11-the
said rods 11 having electricity supplied thereto from the dynamno machine or other
source of electricity 12 and the accumulator 13 as explained in reference to the
parts 4 and 7-the rods 11 are for the purpose of tempering or letting down the
hardness of the wire which thence passes to and is wound upon the winder block
14 in its hardened and tempered state, we prefer the use of additional dynamo 12
and accumulator 13 in preference to taking the electricity for tempering from the
dynamo 4 and accumulator 7.
The card grinding and pointing apparatus comprises discs of emery 15 having
steps, projections, and recesses 16. 16 formed "in and in" or opposite each other
on or in the faces thereof-the step, projections and recesses are formed by the
radial curved corrugated or waved lines 17. 17. and which line 17 and disc 15 are
tapered or feathered near its circumference as shewn at 17ª Fig 8-The said discs
are mounted upon a flanged boss 18 and the projections on one dis: are opposite
the recesses on the next disc thus leaving sufficient space for the teeth under
operation to pass between the discs-At 19 is a screw collar for securing the several
discs in position as shewn at Fig 5-The long boss 20 has a square hole 21 so that
on the boss being placed within the slide 22 and the square shaft 23 introduced to
the boss 20 the latter is held securely and caused to rotate by the pulley 24-At
25. 25. 25 are its supporting brackets-By means of the handle 26 worms 27. 27-
worm wheels 28-screw 29 the slide 30 and cross slide 31 carrying the enery discs
15, the latter are readily adjusted in position for acting upon the teeth or cards on
the cylinder 32. The traversing to and fro or lateral motion is obtained by means
of the pulley 33 and its pinion 34 driving the wheel 35 and wheel 36 which rotates
the shaft 37 and by the worm 38 worn wheel 39 rack pinion 40 and rack 41 the slide
22 is traversed on the cross slide 31-The reverse motion being secured by means
of the clutch box 42 rod 43 and stop pieces 44 coming in contact with stop 45
Having thus fully described the nature and particulars of this our said invention
together with the manner in which the same is to be performed and carried into
practical effect we would have it understood that for the purpose of hardening and
tempering steel wire and grinding cards We claim :
Firstly The application and use in combination of the dynamo machine 4 secondary
battery or accumulator 7 the rods 3. 3. 11. 11 (or the equivalents of 3. 3. 11. 11)
the bath 8 and cleaning apparatus such as 10 the dynamo machine 12 and
accumulator 13 for the purpose specified and herein fully described and illustrated.
Secondly The application and use in combination of the dynamo machine 4
