looker, both of Lower Place, Rochdale, in the County of Lancaster, for
the Invention of "CERTAIN IMPROVEMENTS OR A CERTAIN IMPROVEMENT IN
MACHINES FOR SPINNING OR DOUBLING, COMMONLY KNOWN AS THROSTLES."
Sealed the 7th August 1857, and dated the 10th February 1857.
PROVISIONAL SPECIFICATION left by the said Abraham Royds and John
Kenyon at the Office of the Commissioners of Patents, with their Petition
on the 10th February 1857.
We, ABRAHAM ROYDS, Carder, and JOHN KENYON, Overlooker, both of
Lower Place, Rochdale, in the County of Lancaster, do hereby declare the
nature of the said Invention of "CERTAIN IMPROVEMENTS OR A CERTAIN IMPROVE
MENT IN MACHINES FOR SPINNING OR DOUBLING, COMMONLY KNOWN AS THROSTLES,"
to be as follows:-
"Our said improvements apply to throstle frames, and consist in causing the
bobbins, instead of revolving on the bare spindles as usual, to revolve on.
vertical tubes or hollow stems attached to or forming parts of the lifting plate,
the spindles passing through and revolving in the same tubes without touching
the bobbins.

by the said Abraham Royds and John Kenyon in the Great Seal Patent
Office on the 7th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ABRAHAM
ROYDS, Carder, and JOHN KENYON, Overlooker, both of Lower Place, Rochdale,
in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Tenth day of February, One thousand eight
hundred and fifty-seven, in the twentieth year of Her reign, did, for Her-
self, Her heirs and successors, give and grant unto us, the said Abraham
Royds and John Kenyon, Her special licence that we, the said Abraham
Royds and John Kenyon, our executors, administrators, and assigns, or
such others as we, the said Abraham Royds and John Kenyon, our
executors, administrators, or 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 of "CERTAIN IMPROVEMENTS OR A
CERTAIN IMPROVEMENT IN MACHINES FOR SPINNING OR DOUBLING, COMMONLY
KNOWN AS THROSTLES," upon the condition (amongst others) that we, the said
Abraham Royds and John Kenyon, 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 we, the said Abraham Royds and John Kenyon,
do hereby declare that the nature of our said Invention, and the manner in
which the same is to be performed, are particularly described and ascertained
with the aid of the Drawings hereunto annexed, by the following statement
(that is to say):-
. Our said Invention consists in causing the bobbins of throstle frames to
revolve on or around vertical tubes or hollow stems attached to or forming
parts of the lifting rail, instead of such bobbins revolving on the bare spindles,
as heretofore. The spindles are made to pass through the aforesaid tubes, and
are by means of such tubes restrained from contact with the bobbins, to the
end that any oscillation or vibration attending the motion of the spindles may
not tend to vitiate the uniformity of the drag applied to the bobbins.

piece with it, or they may be made as detached parts, and affixed by set.
screws or otherwise.
:
The manner of their construction and application will be understood by
inspection of the annexed: Drawing and the following explanation, wherein the
parts referred to are identified by the numerical characters marked thereon,
such of the said characters as recur in different Figures indicating the same
parts under different aspects, or similar parts in different examples.
Figure 1 is a front view, and Figure 2 a plan view, of part of, a spindle
1 with its bobbin 2, the latter resting on a portion of the lifting rail 3. The
position of the tube, which constitutes our improvement, is shewn in dotted
lines at 4. Figure 4 is a plan view of the same part of the lifting rail, the
bobbin and spindle being removed. The tube, which in this case forms part of
the lifting rail, is shewn at 4. Figure 3 is a view of the same arrangement as
in Figure 1, but shewing the bobbin, tube, and lifting plate in section, as
if divided by a vertical plane along the line 5 ---- 6 in Figure 4. 4 is the
tube, and 2 the bobbin, as before, the latter having the hole through it partly
enlarged to admit the tube. Figure 5 is another view of the same parts, with
the bobbin and tube in vertical section, the tube 4 being in this instance formed
separately and affixed to the lifting plate. Figure 6 is the corresponding plan
view of part of the lifting rail with the tube only, the spindle and bobbin being
absent. 4 is the tube, provided with a flanch 7, which rests upon the lifting
plate, and is secured thereto by a set screw 8. In this view we have also
shewn the adaptation of a second loose flanched tube interposed between the
fixed tube 4 and the bobbin. This second tube is seen in section at 9. It
forms no part of our Invention, but we approve and recommend its use in
spinning fine counts, as improving the delicacy of the drag and diminishing
the liability of the yarn to fracture.
When the tubes are made in one piece with the lifting plate they may be
bored out by a drill furnished with parallel cutters adapted by their form and
position to clean off the outer surfaces of the tubes at the same time with the
boring, each tube being thus perfected at one operation.
Having thus described our Invention, and the manner of carrying the same
into effect, we shall conclude by stating that we make no claim of Invention or
privilege as respects the loose tube interposed between the fixed tube and the
bobbin, and represented in section at 9 in Figure 5; and that what
do claim as of our Invention, and the subject of the Letters Patent aforesaid,
is, the addition or adaptation to the lifting plates of throstle frames, and the use
therein of fixed vertical tubes interposed between the bobbins and spindles, as
,we

page_text: herein-before.described, whether such tubes form part of the lifting plate or
are separately formed and attached thereto.
In witness whereof, we, the said Abraham Royds and John Kenyon, have
hereunto set our hands and seals, this Fifth day of August, in the
year of our Lord One thousand eight hundred and fifty-seven.
Signed and sealed by the said Abraham
Royds and John Kenyon,. in the
