IMPROVEMENTS IN APPARATUS
Year: 1864

page_text: LETTERS PATENT to Alfred Pemberton, of Eccles, in the County of
Lancaster, Agent, and John Ford, of Ordsall Lane, Salford, in the
said County, Manager, for the Invention of "IMPROVEMENTS IN APPARATUS
カラ
Sealed the 28th March 1865, and dated the 13th December 1864.
PROVISIONAL SPECIFICATION left by the said Alfred Pemberton and
John Ford at the Office of the Commissioners of Patents, with their
Petition, on the 13th December 1864.
We, ALFRED PEMBERTON, of Eccles, in the County of Lancaster, Agent,
and JOHN FORD, of Ordsall Lane, Salford, in the said County, Manager, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN APPA-
RATUS FOR EFFECTING THE DRAG IN THROSTLE SPINNING AND DOUBLING," to be as
follows:-
Our Invention refers to apparatus whereby we are enabled to regulate the
drag according to the requirements of any particular bobbin. For this
purpose we employ a series of set screws or other such apparatus along the
throstle frame, and bearing against the bobbins either directly or by inter-
mediato pieces; by tightening or loosening these, any amount of drag may be
obtained.
According to another method, we use a series of metallic springs or other
elastic apparatus pressing against the bobbins, which springs we sometimes

page_text: combine with flannel or similar soft substance placed in contact with the
bobbins, and we provide them with set screws or similar contrivance for the
purpose of regulating and adjusting their pressure, and thus varying the drag.
We also sometimes form these springs as clips surrounding or partly sur-
rounding the bobbin, or the flannel or other such substance may itself afford
the pressure by being attached to a rigid post regulated by set screws, and
we elevate the bobbins from the rails by filling pieces, and thus make them
affected by our improved drag only.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Pemberton and John Ford in the Great Seal Patent
Office on the 12th June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
PEMBERTON, of Eccles, in the County of Lancaster, Agent, and JOHN FORD,
of Ordsall Lane, Salford, in the said County, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Ier heirs and successors, give and grant unto
us, the said Alfred Pemberton and John Ford, Her special license that we,
the said Alfred Pemberton and John Ford, our executors, administrators, and
assigns, or such others as we, the said Alfred Pemberton and John Ford,
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 APPARATUS FOR
EFFECTING THE DRAG IN THROSTLE SPINNING AND DOUBLING," upon the condition,
amongst others, that we, the said Alfred Pemberton and John Ford, 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 Alfred Pemberton, do hereby declare
the nature of our said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):
:-
.
Our Invention refers to apparatus whereby we are enabled to regulate the
drag according to the requirements of any particular bobbin. For this
purpose we employ a series of set screws or other such apparatus along the
throstle frame, and bearing against the bobbins either directly or by inter-
mediate pieces; by tightening or loosening these set screws or other such
apparatus any amount of drag may be obtained.
In the accompanying Drawings, Fig. 1 represents the most simple form of
our Invention.
The bolster or separate copping rail, as the case may be, is shewn at a
and the bobbin at b; at c is a bracket attached to the bolster or copping
rail, which bracket is tapped for the reception of a set screw d provided with
a disc-formed end e bearing against the flange of the bobbin. By tightening
or loosening the set screw d upon the flange of the bobbin, the amount of
drag may be varied.
In order that the drag may be provided with a constant
starting amount we place a filling piece f upon the rail a, the bobbin resting
thereon.
.
Another method of carrying out our Invention is shewn at Figs. 2 and
3, the former being a plan view and the latter an elevation. The bolster
or copping rail is at a, to which is attached a metallic spring g; this spring
is bent so as to present its surface towards the bobbin, and is at that end
provided with a piece of leather or other soft substance h, bearing by the
clasticity of the spring against the edge of the flange of the bobbin 7. The
spring 9 also carries the projecting stud i upon which the bobbin rests, so as to
render the drag independent of the rail. By tightening or loosening the set
screw which clamps the spring g, the tension thereof may be altered so
as to increase or diminish the drag.
Another method of carrying out our Invention is shewn at Figs. 4 and 5,
the former of which is a cross section and the latter a plan view. The bolster
or copping rail, as the case may be, is at a, upon which is placed a metal
fixing , which bends over one side of the rail at 1, and is provided with
screws m on the other side, which upon being tightened clamp the fixing to
the rail.
The fixing thus described constitutes the framework for carrying the
arrangement which constitutes our Invention, and is shewn as a simple and
convenient method of adapting it; this arrangement is also shewn double,
that is to say, two of the drag apparatus are combined together for two
bobbins, but the necessary parts for each bobbin may be separate if desired.

page_text: The fixing k is provided with lugs n, in which are set screws o; their outward
ends being provided with circular grooves situate within slots formed in bowed
springs p, which springs rest upon the face of the fixing k. At each end of
the springs p are attached pieces of flannel or other such soft substance q
bearing against the peripheries of the bobbins r. By forcing forward the
springs p, or by drawing them backward through the medium of the set
screws o, the flannel or other such soft substance q will be pressed against or
withdrawn from the flanges of the bobbins, and thus the drag will be regu-
lated. To the fixing k is attached a spring t, embracing at its outward
ends the set screws o, by which means the said screws are prevented from
turning by the vibration of the machine; the fixing k is provided with pro-
jecting discs k✶ on which the bobbins run.
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 limit ourselves to the precise constructions and
arrangements, above shewn and described, as many modifications thereof will
readily suggest themselves to all competent persons; but we claim, as secured
to us under the above in part recited Letters Patent, and for the purpose
above set forth, enusing set screws or equivalent apparatus to press directly or
through the intervention of another part or parts upon the flanges of the
.bobbins.
In witness whereof, I, the said Alfred Pemberton, have hereunto set
my hand and seal, this Tenth day of June, in the year of our Lord
One thousand eight hundred and sixty-five.
ALFRED PEMBERTON. (L.S.)
