PROVISIONAL SPECIFICATION left by the said Thomas Morgan at the
Office of the Commissioners of Patents on the 12th September 1882.
THOMAS MORGAN of 21 Cockspur Street Charing Cross in the County of
Middlesex, Engineer and Patent Agent, "IMPROVEMENTS IN THE MANUFACTURE OF
WIRE-CARD-POINTS (a communication to me from abroad by F. Gillet of Aix la
Chapelle, in the Empire of Germany)
The shaping or grinding of two opposite sides of a wire card point is effected by
a machine fastened to the well known card manufacturing apparatus.
This machine is of the following construction:-Two shaping wheels or polishing
wheels are turned by a pulley and a simple pinion in opposite directions.-The two
shaping wheels can be guided in long slots and one of these wheels can be moved
towards the other by means of a lever and a slide.-This lever is turned by an
eccentric and a pusher bar and produces in this manner the advancing of one
shaping wheel towards the other.-A spiral spring drives this wheel back thus
separating the two wheels. The end of the pusher bar passing the above mentioned
lever presses on a spring of a vice or clamp keeping the wire during the process of
sharpening. A set screw regulates exactly the distance. The still connected wire
having received a circular excavation on both sides is led by the wire guide of the
known card manufacturing machine before the knife of said machine and cut in the
middle of the aforesaid excavation.-The wire pieces thus obtained are bent into
prongs and present two sharpened extremities having on both sides a surface.

of an Order of the Lord Chancellor, filed by the said Thomas Morgan in the
Great Seal Patent Office on the 16th March 1883.
THOMAS MORGAN of 21 Cockspur Street Charing Cross in the County of
Middlesex Engineer and Patent Agent, "IMPROVEMENTS IN THE MANUFACTURE
OF WIRE CARD POINTS" (a communication to me from abroad by F. Gillet of Aix
la Chapelle in the Empire of Germany).
I execute the shaping of the wire card points by the aid of a machine illustrated
in the accompanying drawing.-This machine is fixed to the well known card
manufacturing apparatus, its position being where the wire guards are arranged.-
The wire to be shaped passes between the shaping wheels a. b. consisting of hard
metal, or two grinding wheels, which are caused to rotate in opposite directions by
means of two gear wheels v of equal size, and a cord pulley w. Both shaping
wheels may be shifted in slots running in the direction of the wire, and fastened in
any desired position, so that the distances at which the cuts are effected may be
varied at pleasure, thus obtaining wire ends of different lengths. The shaping
wheel b may be brought near to the wheel a, it being connected with a slide c,
which is operated by a lever d.-This lever, one end of which is in connection with
a lever f of the eccentric e, when being turned around its fulcrum at the other end,
pushes the slide c towards the shaping wheel a, thus causing the wheel b to approach
the latter as near as the set screw admits of.-The back movement of the slide,
and consequently the separation of the shaping wheels from each other, within the
limits determined by the position of the set screw is effected by the spring h.-
The lever on the eccentric pushes the lever d only forward, and is again applied
to it after the spring h has drawn back the slide i and lever d.-The lever f has
been prolonged in a straight line beyond its point of contact with the lever d, its
end pushing against a spring m.-Between the latter and a clamping jaw 9 passes
the wire to be shaped, thus when the lever f moves to and fro, the wire is alter-
nately seized and released to be pulled farther on, and to be cut off subsequently,
the shaping of the wire continuing without interruption.-The wire having obtained
a circular excavation k on both sides by the shaping wheels a and b, is led through
the wire guide of the card manufacturing machine referred to under the cutting
knife, and is cut in the middle of said excavations. The wire pieces thus produced
are bent around, forming prongs, the pointed ends of which present two Hattened
sides, as shown in the Drawing.-In case only one side of the wire is to be shaped,
the wheel a is simply omitted, and a plate provided in its stead for holding the wire,
no further material alterations being requisite.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed or put in practice, I
hereby declare that I claim in regard to said Invention :-
(1.) In the manufacture of wire card points the method hereinbefore described
of shaping or grinding excavations on one or both sides of the wire, and cutting it
in the middle of the excavation, thus forming sharp points.
(2.) The arrangement of two adjustable shaping or grinding wheels a and b
rotating in opposite directions by the aid of the gear wheels v and cord pulley w,
in combination with the slide c, operated by the eccentric e and spring h, and
pushing one of the shaping wheels automatically against the wire passing between

page_text: both, further in combination with an automatic clamping device, seizing and
releasing the wire alternately, and consisting of the clamping jaw g, spring m, and
the lever f on the eccentric e.
In Witness whereof I the said Thomas Morgan have hereunto set my hand
and seal this sixteenth day of March in the year of our Lord one thousand
eight hundred and eighty three.
T. MORGAN (L.S.)
