Sealed the 6th November 1874, and dated the 12th May 1874.
PROVISIONAL SPECIFICATION left by the said John James Richardson
at the Office of the Commissioners of Patents, with his Petition,
on the 12th May 1874.
I, JOHN JAMES RICHARDSON, of Horsforth, near Leeds, in the County
of York, do hereby declare the nature of the said 'Invention for "Im-
PROVEMENTS IN MACHINERY FOR POINTING WIRE USED IN THE MANUFACTURE OF
NEEDLES, PINS, CARD AND HACKLe Teeth, and foR OTHER PURPOSES," to be as
follows:-
The object of my Invention is to obviate the defects of grinding
machines having curved or conical stones, preventing thereby great
waste of material in cutting the stones into a curved or conical shape,
and effecting thereby also a great reduction of labour in getting the
stones up ready for work.

page_text: -
I employ a stone parallel on the face or periphery similar to those
used in hand grinding, but it may be made of any suitable width. They
are mounted by preference in wooden centres (though not necessarily
so), similar to those described on a machine for which Letters Patent
were granted to James Rhodes and myself, No. 2747, October 19th,
A.D. 1870.
On the main table I provide an adjustable top table on which is
mounted a rubber to which a reciprocating motion is imparted through
a connecting rod from some suitable motive power.
I provide in front of the rubber one or more pressing plates carried in
adjustable bearings to give the required pressure to the wires during the
pointing operation. The position of these plates may be varied. and
regulated to suit the various thicknesses and lengths of wire. The pins
being placed under the rubber and presser plates are caused to move
backwards or forwards with a rotary motion on the stone, the required
pressure being given to the rubber and presser plate by means of levers
and weights, or equivalent means.
The top table is mounted on pivots carried and made to work in
adjustable slides fixed by means of suitable brackets to the main
table. For regulating its position with respect to the stone at the back
of the machine is provided a rack arrangement, into it is geared a
pinion to which motion is imparted by means of a worm wheel and
worm, or equivalent means actuated by some suitable motive power.
In order to regulate the shape and length of point to be ground the
top table is elevated and retained at any required angle by means of a
radial bracket.
-
On the front of the top table is provided an adjustable gauge for
regulating the different lengths of wire to be ground.
Instead of making the top table move towards the stone, in some cases
I by preference move the stone towards the table.
Other parts of the machine not mentioned may be of similar con-
struction to those described in Patent, No. 2747, October 19th, A.D. 1870,

filed by the said John James Richardson in the Great Scal Patent
Office on the 12th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JAMES RICHARDSON, of Horsforth, near Leeds, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of May, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John James Richardson, Her
special licence that I, the said John James Richardson, my executors,
administrators, and assigns, or such others, as I, the said John James.
Richardson, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, tlie Channel Islands, and Isle of Man, an In-
vention for "IMPROVEMENTS IN MACHINERY FOR POINTING WIBE USED IN THE
MANUFACTURE OF NEEDLES, PINS, CARD AND HACKLE TEETH, AND FOR OTHER
PURPOSES," upon the condition (amongst others) that I, the said John
James Richardson, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John James Richardson, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Drawings and to the letters of reference marked thereon, that is
to say :-

page_text: and effecting thereby also a great reduction of labour in getting the
stones up ready for work.
I employ a stone parallel on the face or periphery similar to those
used in hand grinding, but it may be made of any suitable width. They
are mounted by preference in wooden centres (though not necessarily
so), similar to those described on a machine for which Letters Patent
were granted to James Rhodes and myself, No. 2747, October 19th
A.D. 1870.
On the main table I provide an adjustable top table on which is
mounted a rubber to which a reciprocating motion is imparted through
a connecting rod from some suitable motive power.
I provide in front of the rubber one or more pressing plates carried
in adjustable bearing to give the required pressure to the wires during
the pointing operation. The position of these plates may be varied and
regulated to suit the various thicknesses and length of wire. The wire
being placed under the rubber and presser plates are caused to move
backwards or forwards with a rotary motion on the stone, the required
pressure being given to the rubber and presser plate by means of levers
and weights.or equivalent means.
The top table is mounted on pivots carried and made to work in
adjustable slides fixed by means of suitable brackets to the main table.
A rack arrangement is provided for regulating its position with regard.
to the stone at the back of the machine, into it is geared a pinion to
which motion is imparted by means of a worm wheel and worm, or
equivalent means actuated by some suitable motive power.
In order to regulate the shape and length of the point to be ground
the top table is elevated and retained at any required angle by means
of a radial bracket.
On the front of the top table an adjustable gauge is provided for
regulating the different lengths of wire to be ground.
Instead of making the top table move towards the stone, in some cases
I by preference move the stone towards the table.
Other parts of the machine not mentioned may be of similar con-
struction to those described in the Specification of Patent No. 2747,
October. 19th A.D. 1870.

page_text: attached hereunto two sheets of Drawings marked with letters of
reference, corresponding marks indicating the same parts in the various
Figures.
Figure 1, Sheet 1, represents a side elevation.
Figure 2 a front elevation.
. Figure 3, Sheet 2, represents a plan looking on the top.
I employ a stone a parallel on the face or periphery, that is to say, the
diameter of the stone is the same throughout. This stone is similar to
those used in land grinding and may be of any width. I by preference
mount the stone a in wooden centres b (though not necessarily so), the
shaft c being constructed to suit the bearings. The stone a may be
raised or lowered by means of the screws d actuated through the hand
wheels e, the wooden centres being fixed in the sliding carriers f fitted
within the framework g.
I fix the, main table h on the framework 9 and on it is provided an
adjustable top table i. Over the top table i is mounted a rubber j which
also acts as a pressing plate. Between the rubber or pressing plate j
and the top table i the wires to be ground are placed, and in order to
give them a rolling motion during the operation of grinding, similar to
that given in hand grinding I impart to the rubber or pressing plate ja
reciprocating motion transmitted thereto by means of the crank
through the connecting rod 7 from the driving pulley m. Other.
equivalent or known means may be employed for giving the required
motion to the rubber or pressing plate j.
In order to give the required pressure to the rubber or pressing plate j
I by preference employ the spring n to the rubber or pressing plate j
through the carriage o and roller p. The attendant may vary the
pressure of the spring n by means of the regulating screw q.
serves
In order to lift the rubber or pressing platej I provide a pinion "
which I mount on the shaft s; in this case the regulating screw q
as a rack for the pinion 7, so that by turning the hand wheel t the
regulating screw q may be raised or lowered, carrying with it the rubber
or pressing plate j which is attached thereto by means of the spring n,
carriage o, and side plates which also serve as guides to the rubber j
when in operation. But when pressure is required to be given I-retain

page_text: the pinion in a fixed position by means of the pawl v and ratchet
wheel w. By the pinion being fixed in position it serves as a nut for
the regulating screw q, the rods x, which are fitted so as to slide freely
in the bracket y and are employed as guides for the carriage o.
In order to cause the required friction on the wires one or more
layers of india-rubber or its equivalent may be fixed to and between the
rubber or pressing plate j and the top table i. When preferred a
wrought-iron or steel plate may be let into the top table i under the
rubber or pressing plate j, the thickness of which may be so reduced to
a fine edge at the point of its nearest contact with the stone a and
consequently the wire may be brought nearer to the stone a.
In order to give the required angle or vary the length of the point of
the pins I mount the top table i on the pivots or studs 1 and 2 on which
pivots or studs are provided the bushes 3 and 4; these are fitted so as
to slide within the adjustable brackets 5.
In order to vary the angle of the top table i and its distance from the
stone a I provide on the main table the adjustable rack 6, the angle of
which may be varied to any required extent by means of the nut 7 and
screw 8. The pinion 9 is made to gear into the adjustable rack 6 and
carried in suitable bearings 10 on the top table i.
It will be readily understood that by causing the pinion 9 to move
up or down on the rack 6, the top table i is carried backwards or
forwards, thereby at the same time the angle of the top table i with
regard to the stone a is varied in accordance with the angular position
of the adjustable rack 6. The required motion may be transmitted to
the rack pinion 9 from the band wheel 11 through gearing 12.
In order to regulate the length or amount of wire projecting from
between the top plate i and the rubber or pressing plate j I provide the
adjustable gauge or plate 13, which is fitted so as to slide freely on the
rods 14 and 15 attached to the bracket 16. The required adjustment is
imparted thereto by means of the screw 17. The plate 18, which is
attached to the rubber or pressing platej, is also employed for regulating
the projecting wire, and is adjusted by means of the adjusting screw 19.
and nuts 20.
In order to set the wire parallel I provide the plate 21, which may be a
of any required width, and secured to the top table i by any convenient

page_text: In order to keep the top table i from tilting I fix underneath the top
table i a bracket 22 to slide (when the table is moved) within a recess 23
provided in the rack 6, as shewn.
Having now described the nature of my said Invention and the
manner in which the same may be performed, I would remark in
conclusion that I do not limit myself to the exact limits, details, and
configuration of the parts I have explained and shewn, as the same may
of course be varied or modified without in any way departing from the
nature of my Invention, but what I do claim and desire to be secured to
me by Letters Patent is,—
First. The arrangement, construction, and application of the adjustable
top table i, and parts connected therewith for effecting the adjustment,
substantially as herein set forth.
Second. The arrangement, construction, and application of the rubber
or pressing plate j, in combination with a reciprocating motion for
giving the required motion to the wire, substantially as and for purposes
herein set forth.
Third. The arrangement, construction, and combination of parts in
connection with the rubber or pressing plate for giving and transmitting
the required pressure thereto, also for guiding, raising, and lowering
the same, substantially as and for purposes herein set forth.
Fourth. The arrangement of the various parts of the machine in
combination, and the application of a parallel stone or stones of the
same diameter throughout, substantially as and for purposes herein set
forth.
In witness whereof, I, the said John James Richardson, have
hereunto set my hand and seal, this Eleventh day of November,
in the year of our Lord One thousand eight hundred and seventy-
JOHN JAMES RICHARDSON. (L.s.)
