Year: 1860

page_text: LETTERS PATENT to Samuel Wheatley and Alfred Milnes, of the City of
Manchester, in the County of Lancaster, for the Invention of "AN
IMPROVED GRINDING STRICKLE FOR GRINDING THE CARDS ON THE CYLINDERS Or
GARDING ENGINES."
Sealed the 11th October 1860, and dated the 19th April 1860.
PROVISIONAL SPECIFICATION left by the said Samuel Wheatley and
Alfred Milnes at the Office of the Commissioners of Patents, with their
Petition, on the 19th April 1860.
We, SAMUEL WHEATLEY and ALFRED MILNES, of the City of Manchester, in
the County of Lancaster, do hereby declare the nature of the said Invention
for "AN IMPROVED GRINDING STRICKLE FOR GRINDING THE CARDS ON THE CYLINDERS
OF CARDING ENGINES," to be as follows:-
Our Invention consists in giving a compound sliding motion to the plate or
flat surface on which the emery is placed, in order to obtain a fine carding
point and grind the sheet cards true with one another. The said plate works
in grooves or slides upon another plate,also working upon rods or in grooves.
The upper slide has a to-and-fro motion imparted to it in a direction parallel
with the sheets of the cards by means of a cam,eccentric, or other contrivance,
and the lower slide to which the grinding plate is attached has a transverse
to-and-fro motion by the action of two cams or eccentrics near each end, put
in motion by bevil gearing from the driving shaft of the apparatus. The
required position of the grinding plate and slides being regulated by screws,

page_text: and afterwards firmly fixed by lock nuts. The aforesaid improved compound
motion causes the emery to be changing its position for a considerable time,
and thus grind a sharp carding point.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Wheatley and Alfred Milues in the Great Seal
Patent Office on the 18th October 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, SAMUEL
WHEATLEY and ALFRED MIL.NES, of the City of Manchester, in the County of
Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of April, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her reign
did, for Herself, Her heirs and successors, give and grant unto us, the said
Samuel Wheatley and Alfred Milues, Her special licence that we, the said
Samuel Wheatley and Alfred Milnes, our executors, administrators, and
assigns, or such others as we, the said Samuel Wheatley and Alfred Milnes,
our 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 night make, use, exercise, and vend
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED GRINDING STRICKLE
FOR GRINDING THE CARDS ON THE CYLINDERS OF CARDING ENGINES," upon the
condition (amongst others) that we, the said Samuel Wheatley and Alfred
Milnes, our executors or administrators, by an instrument in writing under
our, or their, or one of their hands and seals, 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 we, the said Samuel Wheatley and Alfred Milnes,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):-
Our Invention consists in giving a compound sliding motion to the plate or
flat surface on which the emery is placed in order to obtain a fine carding
point, and grind the sheet cards true with one another. The said plate works

page_text: in grooves or slides upon another plate also working upon rods or in grooves.
The upper slide has a to-and-fro motion imparted to it in a direction parallel
with the sheets of the cards by means of a cam, eccentric, or other contrivance;
and the lower slide to which the grinding board is attached has a transverse
to-and-fro motion by the action of two cams or eccentrics near each end, put
in motion by bevil gearing from the driving shaft of the apparatus. The
required position of the grinding board and slides being regulated by screws,
and afterwards firmly fixed by lock nuts. The aforesaid improved compound
motion causes the emery to be changing its position for a considerable time,
and thus grind a sharp carding point.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Fig. 1 is a front
elevation; Fig. 2 a plan; Fig. 3 an end view; and Figs. 4 and 5 transverse
sections of our improved differential card grindingapparatus for grinding the
cards of carding engines, or other similar purposes.
The thin board of wood upon which the emery is placed is shown at a, it is
screwed to a metal plate or slide 6, having at each end transverse projections c
truly parallel with each other, and formed with grooves d, so that the said
plate b cau slide transversely upon another plate e, which is mounted with
four carriers or bearings/fitting the rods g fixed at their ends to the standards
connected to the pins i, which fit brackets attached to the outside of the
bends of the card cylinder, the rods and slides being adjusted, as required, by
the set screws k, and kept firm by the lock nuts 1. In the standards h are
bearings m for the shaft n, which is turned either by hand or by the driving
pulleys o. In the upper plate 6 there is an oblong recess p, in which is placed
an eccentric fastened to the spindler working in a bearing 7 fixed to the
rods g. To the spindler is fixed the bevil wheel s gearing into the bevil
pinion t working in a bearing joined to or forming part of the bearing >', so
that when the driving shaft is turned and the eccentric made to revolve the
two plates bandehave a to-and-fromotion parallel with the shaft. In the lower
plate 6 there are two oblong recesses, in each of which is placed an eccentricu
fastened to a spindle v working in the upper plate e, to which spindles are
fixed the bevil wheels w gearing into the broad pinions z fixed to the shaft n,
so that when the eccentrics are made to revolve they give a to-and-fro motion
to the lower plate in a transverse direction to the first motion, by which means
a compound to-and-fro sliding motion is given to the board upon which the
emery is placed, and produces a fine carding point quite equal to thatobtained
by the most careful hand grinding. The breadth of the pinions are in pro-
portion to the traverse of the two slides, the teeth of the bevil wheels w

page_text: sliding to and fro upon the teeth of the pinions, so that revolution may be
obtained at all points of the traverse. In the Figures the pinion t is intended
to have twelve teeth, and the bevil wheels forty-seven teeth, and the broad
pinions eleven teeth, and the bevil wheels un forty-six teeth; but these
numbers may be varied as desired. The dimensions and strength of the afore-
said grinding apparatus are varied according to the sizes of the card cylinders;
Those of combing machines are generally small, and the strickle is therefore
made in proportion. When desired, a strickle may be applied to each cylinder
of the combing machine, so as to be always ready for grinding, and all the
stricklos worked from one driving shaft. We may here remark that the main
feature of our Invention consists in giving a compound sliding movement to
the emery board and slide to which it is connected, which result may be
obtained by cams or eccentrics acting upon slides of various forms, but the
arrangement shewn in the Drawing is preferred, as being one of the most
economical. We also drive two or more machines from the same shaft, when
found desirable.
Having now described the nature of our said Invention, and the manner in
which the same is to be performed, we desire it to be distinctly understood that
we do not confine ourselves to the precise details herein set forth; but we claim
as our Invention, and which to the best of our knowledge and belief has
not been hitherto used within the realm, the employment of cams or eccen-
trics in connection with two slides, for the purpose of giving a compound sliding
motion to the emery and board of the grinding strickle for grinding the cards
or combs of carding engines and combing machines, as all such improvements
as herein described and illustrated in the accompanying Sheet of Drawings.
In witness whereof, we, the said Samuel Wheatley aud Alfred Milnes,
have hereunto get our hands and seals, this Tenth day of October, in
the year of our Lord One thousand eight hundred and sixty.
