page_text: And whereas by an Assignment dated the Eleventh day of January One thousand
eight hundred and eighty two, and duly registered in the Great Seal Patent Office
aforesaid all the share, right, title and interest of the said Thomas Goodbehere in
the said Letters Patent became vested in me the said Samuel Brooks.
And whereas since the said Letters Patent were so assigned I the said Samuel
Brooks have ascertained that the claims as originally made are too wide for which
reason I am desirous of disclaiming all claims except the second, and of striking
out parts of the Specification to which the now omitted claims refer, by a Disclaimer
and Memorandum of Alteration.
NOW KNOW YE therefore that I the said Samuel Brooks by and with the
consent of Her Majesty's Solicitor General do alter and amend the said Specification
as follows that is to say :-
"
Referring to the Queens Printers Copy of the said Specification, on page 4, I
strike out the whole of lines 4 and 5. In line 6 I strike out the word "Secondly'
and in the same line I insert after the word "holding" the word "down." I strike
out the whole of the words in lines 8, 9, 10, 11, 12 and 13. After the word
"figures" in line 16, I insert the figures and word "1, 2, 3 and 4" and after the
word "thereon" in line 17, I insert the words and figures "Figures 5 and 6 repre-
"sent parts of the machinery which/are not claimed as forming part of the patented
"invention" I strike out the whole of lines 18 to 29 inclusive. In line 30 after
the word "wharves" I strike out the words "are now" and I insert the words
' and with them the spindles have commonly been." In line 31 I-strike out the
words "and before the," I also strike out the whole of line 32, and in line 33 I
strike out the words "and the plates moved sideways or backward" and in the
same line after the word "This" I insert the word "plan." On page 5 line 1
after the word "frame" I insert the words "as indicated by dotted lines in the
drawings." I strike out all the words in lines 5 to 24 inclusive. In line 26, I
strike out all the words after the word " same " and I strike out the whole of
line 27, excepting the words we claim." I strike out the whole of the first
claiming clause, also the word " Secondly" line 30, and I insert in that line the
word "down" after the word "holding." After the word "doffed" line 31, I
insert the words "applied to the machinery for spinning and doubling known as
ring and traveller throstles and doublers." I strike out the whole of the third,
fourth and last claiming clauses.
"
"
And in order that the effect of the said Disclaimer and Memorandum of
Alteration may be fully understood, I annex a Copy of the said Specification
(omitting the introductory and concluding clauses thereof) as it will appear after
the above specified alterations have been made therein.
"Our Invention is applicable to the machinery for spinning and doubling
"known as ring and traveller throstles and doublers, and consists,
"In certain improved apparatus for holding down the wharves when the bobbins
" are being doffed.
"And in order that our invention may be fully understood and readily carried
" into operation, we will proceed to describe the accompanying Sheet of Drawings,
"reference being had to the Figures 1, 2, 3 and 4 and letters marked thereon.
Figures 5 and 6 represent parts of the machinery which are not claimed as
forming part of the patented invention.
"
"
In doffing the bobbins the wharves and with them the spindles have commonly
"been prevented rising by guards fixed to plates that are held in position by set
screws. This plan causes considerable delay, and in order to obviate it we fix
" the guards 9 shewn in Figures 1 and 2, to the rod h, which can be swivelled
partly round by the handle i at one end of the frame as indicated by dotted
"lines in the drawings. By this means all the wharves can be secured and
"released simultaneously, or the rod h can be moved back until the guards g are
" clear of the wharves, as shewn in Figure 3, or endwise, as shewn in Figure 4.

page_text: LETTERS PATENT to Samuel Brooks, of the Union Iron Works, West
Gorton, near Manchester, in the County of Lancaster, Machine
Maker, and George Harrison, of the same Place, Manager, and
Thomas Goodbehere, of the same Place, Foreman, for the Invention
Sealed the 4th September 1874, and dated the 29th April 1874.
PROVISIONAL SPECIFICATION left by the said Samuel Brooks, George
Harrison, and Thomas Goodbehere at the Office of the Com-
missioners of Patents, with their Petition, on the 29th April
1874.
We, SAMUEL BROOKS, of the Union Iron Works, West Gorton, near
Manchester, in the County of Lancaster, Machine Maker, and GEORGE
HARRISON, of the same Place, Manager, and THOMAS GOODBEHERE, of
the same Place, Foreman, do hereby declare the nature of the said

page_text: Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING,"
to be as follows:-
Our Invention is applicable to the machines for spinning and
doubling, known as ring and traveller throstles. In these machines the
spindles usually revolve in a cast-iron tube, in the lower end of which is
a plug of white metal forming the footstep. This mode of construction
is objectionable, as the tubes are very difficult to clean, and when worn
they cannot be repaired. In order to remedy these defects we support
the spindle in a brass bearing let into the upper end of the tube, and the
footstep is screwed into the lower end of the tube. When the tubes
require cleaning the footsteps can be unscrewed, and the tubes are then
ready to be cleaned out.
In doffing the full bobbins the wharves are prevented rising by guards
fixed to plates that are held in position by set screws, and before the
wharves can be taken off the spindles these screws have to be slackened
and the plates moved sideways or backwards, this causes considerable
delay, and in order to obviate it we fix the guards to a rod, which can
be swivelled partly round by a handle at one end of the frame, or
the rod can be moved endwise until the guards are clear of the
wharves.
In winding the yarn or thread on the bobbin it is very desirable to
keep it clear of the upper flange; and in order to accomplish this we
attach the chains that lift the copping rail to eccentric cams fixed to
the side shafts. These cams cause the lifting rail to rise and fall rapidly
near the top of the bobbin, thereby producing a tapered end, and
allowing the bobbin to be made with the upper flange much smaller
than the lower one, or the eccentric can be placed on the lever, or
between the lever and the side shaft.
Instead of bowls for acting on the heart of the ordinary copping
motion we use steel ribs. This mode of construction reduces the dwell
at the ends of the bobbins and produces a better shaped bobbin. The
heart revolves in an oil cup to prevent injury by friction.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Brooks, George. Harrison, and Thomas
Goodbehere in the Great Seal Patent Office on the 28th October
1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
BROOKS, of the Union Iron Works, West Gorton, near Manchester,
in the County of Lancaster, Machine Maker, and GEORGE HARRISON,
of the same Place, Manager, and THOMAS GOODBEHERE, of the same
Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of April, 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 us, the said Samuel Brooks, George Harrison, and Thomas
Goodbehere, Her special license that we, the said Samuel Brooks, George
Harrison, and Thomas Goodbehere, our executors, administrators, and
assigns, or such others as we, the said Samuel Brooks, George Harrison,.
and Thomas Goodbehere, 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 MACHINERY FOR SPINNING AND DOUBLING,"
upon the condition (amongst others) that we, the said Samuel Brooks,
George Harrison, and Thomas Goodbehere, our executors or adminis-
trators, by an instrument in writing under our, or their, or one
of our or 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 Brooks, George Harrison,
and Thomas Goodbehere, do hereby declare the nature of our said Inven-
tion, 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) :-

page_text: Brooks, Harrison, & Goodbehere's Impts. in Machinery for Spinning, &c.
Our Invention is applicable to the machinery for spinning and
doubling known as ring and traveller throstles and doublers, and
consists,―
First. In an improved mode of constructing the bearings and footsteps
of the spindles.
Secondly. In certain improved apparatus for holding the wharves
when the bobbins are being doffed.
Thirdly. In causing the lifting rail to move rapidly at the top of
the lift to keep the yarn or thread clear of the upper flange of the
bobbin.
Fourthly. In substituting steel ribs instead of bowls for acting on the
heart of the copping motion.
.
And, lastly. In the application of an oil cup to lubricate the heart.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters
marked thereon.
In ring and traveller throstles of the present construction the spindles
'usually revolve in a cast-iron tube, in the lower end of which is a plug"
of white metal forming the footstep. This mode of construction is
objectionable, as the tubes are very difficult to clean, and when worn
they cannot be repaired. In order to remedy these defects we support
the spindle in the manner shewn in Fig. 1. a is the spindle; b, the
wharve; c, the ordinary bobbin rail, in which the cast-iron tube d is
screwed. The brass bearing e is let into the upper end of the tube, and
the footstep is screwed into the lower end of the tube. There are side
holes in the bearing and footstep for the passage of the oil or other
lubricant. When the tubes require cleaning the footsteps can be
unscrewed, and the tubes are then ready to be cleaned out.
In doffing the bobbins the wharves are now prevented rising by guards
fixed to plates that are held in position by set screws, and before the
wharves can be taken off the spindles these screws have to be slackened
and the plates moved sideways or backward. This causes considerable
delay, and in order to obviate it we fix the guards g, shewn in Figs. 1
and 2, to the rod h, which can be swivelled partly round by the handle i

page_text: at one end of the frame. By this means all the wharves can be secured
and released simultaneously, or the rod h can be moved back until the
guards are clear of the wharves, as shewn in Fig. 3, or endwise, as
shewn in Fig. 4.
In winding the yarn or thread on the bobbin it is very desirable to
-
-
keep it clear of the upper flange; and in order to accomplish this we
attach the chains that lift the copping rails to eccentric cams, as shewn
in Figs. 5 and 6, in which views j is one of the copping rails, the guide
rods of which are connected by chains / to the pulleys m¹ on the side
shafts m, to which are also fixed the eccentric cams 7 connected by
chains to the ordinary bell-cranked levers n. These eccentric cams
cause the lifting rail to rise and fall rapidly near the top of the bobbin,
thereby producing a tapered end, and allowing the bobbin to be made
with the upper flange much smaller than the lower one, or the eccentric
cam can be placed on the bell-crank lever, or between the lever and the
side shaft.
Instead of bowls for acting on the heart n¹ of the ordinary copping
motion as now customary we use steel ribs o, which are let into the
bell-cranked levers n, and are held in contact with the heart by the
weight of the lifting rails. This mode of construction reduces the dwell
at the ends of the bobbins and produces a better shaped bobbin. The
heart'n' revolves in an oil cup q to prevent injury by friction. This oil
cup is particularly beneficial when our steel ribs o are used, but it may
be applied when the ordinary antifriction bowls are used.
Having thus stated the nature of our Invention, and described the
manner of performing the same, we wish it to be understood that we do
not limit ourselves to the details given, and that we claim,-
First. The improved mode of constructing the bearings and footsteps
of the spindles, as shewn and described in reference to Fig. 1.
Secondly. The improved apparatus for holding the wharves when the
bobbins are being doffed, as shewn and described in reference to Figs. 1,
2, 3, and 4.
Thirdly. The eccentric cam, shewn in Fig. 5, for causing the lifting
rail to move rapidly at the top of the lift for the purposes described.

page_text: Fourthly. Substituting steel ribs in lieu of bowls for acting on the
heart of the copping motion.
And, lastly. The application of an oil cup to lubricate the heart.
In witness whereof, I, the said Samuel Brooks, for myself and on
behalf of the said George Harrison and Thomas Goodbehere, have 5
hereto set my hand and seal, this Twenty-seventh day of October,
One thousand eight hundred and seventy-four.
S. BROOKS. (L.S.)
