Year: 1861

page_text: Sealed the 4th February 1862, and dated the 9th August 1861.
PROVISIONAL SPECIFICATION left by the said James Gray, Thomas
Kershaw, Benjamin Crowther, and Alfred Dean at the Office of the
Commissioners of Patents, with their Petition, on the 9th August 1861.
We, JAMES GRAY, of Manchester, in the County of Lancaster, Cotton
Spinner, THOMAS KERSHAW, of the same Place, Manager, BENJAMIN CROWTHER,
of the same Place, Mechanic, and ALFRED DEAN, of the same Place, Roller
Coverer, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN MULES FOR SPINNING," to be as follows:-
Our Invention relates to the guides through which the material passes from
the creel, and which cause it to be traversed along the surface of the rollers;
these guides as ordinarily used are in two distinct rows, the front row receiving
motion from the back by means of pins which pass into slots.
According to our Invention we form the two rows in one piece, or connect
them by soldering or other method, which firmly unites them together a space
between them receiving the rollers. The guides so formed are mounted upon
a bar to which a traversing motion is imparted in the ordinary manner.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
GRAY, of Manchester, in the County of Lancaster, Cotton Spinner, THOMAS
KERSHAW, of the same Place, Manager, BENJAMIN CROWTHER, of the same
Place, Mechanic, and ALFRED DEAN, of the same Place, Roller Coverer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of August, One thousand eight hundred
and sixty-one, in the twenty-fifth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto us, the said James Gray, Thomas
Kershaw, Benjamin Crowther, and Alfred Dean, Her special license that.
we, the said James Gray, Thomas Kershaw, Benjamin Crowther, and
Alfred Dean, our executors, administrators, and assigns, or such others
as we, the said James-Gray, Thomas Kershaw, Benjamin Crowther, and
Alfred Dean, 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 might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN.
MULES FOR SPINNING," upon the condition, amongst others, that we, the said
James Gray, Thomas Kershaw, Benjamin Crowther, and Alfred Dean, by an
instrument in writing under our hands and seals, (or under the hand and seal
of one of us) 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 James Gray, do. hereby declare the
nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (and accompanying Drawings). that is to say
"
Our Invention refers to an arrangement and construction of guides through.
which the material passes on its way to, and while passing between the rollers,
and is shewn in three views in the accompanying Drawing, in which Fig. 1.
represents the rollers of a mule in section with our improved guides adapted.
Fig. 2 is a face view. of one set of guides, and Fig. 3 a plan view thereof.
The rollers are shewn at a, a', a², carried by the usual stand b, at c is the

page_text: ordinary bar to which the hook guides are usually attached, and to which is
imparted a traversing motion, as is well understood. To this bar is attached
a tin bracket d, which carries a plate bent round under the rollers a, and
upward between the rollers a, a', as at e, f; these two portions e, f, are pro-
vided with slits, as seen at Fig. 2, through which slits the material passes, as
shewn by the red line in Fig. 1; when, therefore, the bar c is caused to
traverse, the two guides e, f, move together and keep the same relative
positions. The said guides e, f, are fixed to the bar c in detached portions, one
of which the face view Fig. 2 represents; and these are of a suitable width
to occupy the required position between two cap bars, and they are adapted to
the bar c by means of screws as at g, which screws pass through slots in the
brackets d, by which means an exact adjustment of guides may be effected.
The part which passes under the rollers a is provided with an aperture
(Fig. 3) through which dust or other extraneous matters may fall.
Having thus described and ascertained the nature of our said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that we do not confine ourselves to the exact arrangement and construction
shewn and described as modifications may be made, in which the principle is
still preserved of causing the two sets of guides to move together; but we
claim as secured to us under the above in part recited Letters Patent, con-
structing the guides above alluded to, in one piece, or otherwise arranging
them, so that they shall move. together; also adapting them in detached
portions for the convenience of adjustment.
In witness whereof, I, the said James Gray, have hereunto set my
hand and seal, this Seventh day of February, in the year of our Lord
One thousand eight hundred and sixty-two.
JAMES GRAY. (L.S.)
