IMPROVE- MENTS IN SPINNING MACHINERY
Year: 1874

page_text: LETTERS PATENT to Henry A. Chapin, of 38, Southampton Buildings,
Chancery Lane, London, Engineer, for the Invention of "IMPROVE-
MENTS IN SPINNING MACHINERY."
Scaled the 6th November 1874, and dated the 15th May 1874.
PROVISIONAL SPECIFICATION left by the said Henry A. Chapin at
the Office of the Commissioners of Patents, with his Petition, on
the 15th May 1874.
I, HENRY A. CHAPIN, of 38, Southampton Buildings, Chancery Lane,
London, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SPINNING MACHINERY," to be as follows:-
:―
This Invention consists in improvements in spinning machinery, and
relates to the ring of the ring and traveller used in spinning machinery.
It is found that great delay and inconvenience is caused by the ring
becoming clogged up with the particles of fibres thrown off in the action
of spinning, and that great delay is caused by the necessary removal of
the ring and cleaning thereof. The clogging also very frequently causes
the yarn to break.

page_text: In my present improvements I cause the upper part of the ring to be
perforated or made open, forming a sort of skeleton frame, or I perforate
the bobbin rail upon which the ring is placed with a series of holes or
openings, or in some cases I use both methods. The traveller is not in
any way checked or disturbed in its motion by these openings, and the
particles of the fibres as they are released from the yarn fly off by the
force of the current of air caused by the traveller and bobbin through
these openings, and prevent the clogging. I also make a hole at the
side of the ring for insertion of the traveller to avoid the necessity of
removing the ring for that purpose. The said opening may be closed or
not with a screw or other means.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry A. Chapin in the Great Seal Patent
Office on the 9th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY A.
CHAPIN, of 38, Southampton Buildings, Chancery Lane, London, Engincer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Fifteenth day of May, 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 me, the said Henry A. Chapin, Her special license
that I, the said Henry A. Chapin, my executors, administrators, and
assigns, or such others as I, the said Henry A. Chapin, my 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
SPINNING MACHINERY," upon the condition (amongst others) that I, the
said Henry A. Chapin, my, executors or administrators, by an instrument
in writing under my, 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

page_text: be filed in the Great Seal Patent Office within six calendar montlis
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry A. Chapin, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention consists in improvements in spinning machinery, and
relates to the ring of the ring and traveller used in spinning machinery.
It is found that great delay and inconvenience is caused by the ring
becoming clogged up with the particles of fibres thrown off in the action
of spinning, and that great delay is caused by the necessary removal of
the ring and cleaning thereof. The clogging also very frequently causes
the yarn to break.
In my present improvements I cause the upper part of the ring to be
perforated or made open, forming a sort of skeleton frame, or I perforate
the bobbin rail upon which the ring is placed with a series of holes or
openings, or in some cases I use both methods. The traveller is not in
any way checked or disturbed in its motion by these openings, and the
particles of the fibres as they are released from the yarn fly off by the
force of the current of air caused by the traveller and bobbin through
these openings, and prevent the clogging. I also make a hole at the
side of the ring for insertion of the traveller to avoid the necessity of
removing the ring for that purpose. The said opening may be closed or
not with a screw or other means.
In the accompanying Drawings, forming part of this Specification,
Figure 1 is a plan; Figure 2, an elevation partly in section; Figure 3, a
plan of the traveller detached; Figure 4, a plan of the ring detached ;
Figure 5, an elevation of the same.
a is the bobbin, which receives its rotating movement in any appro-
priate manner, and 6 the open or skeleton ring, which is mounted upon
the bar c of the spinning frame, which bar receives an up-and-down
movement, and all the length of the bobbin, and of which the speed is
regulated by appropriate mechanism, according to the size of the thread
which is being spun; d is the traveller made of a wire thread preferably
of steel, and slightly bowed, as indicated in Figure 3. When the
materials are used damp, such as jute, I make. this traveller in nickel or

page_text: in steel plated with nickel for entering and extracting the traveller
without disturbing any part of the machine. I make a small hole e in
the upper part of the ring, Figures 2 and 5, which does not interfere
with the working of the traveller, because the extremity of the traveller,
which bears against the internal collar of the ring, see Figure 1, is always
held down and pressed against the support or arm c. The two arrows in
Figure 1 respectively represent the direction of the rotation of the
bobbin, and the direction or position of the traveller d caused by that
rotation.
:
I have mentioned that the ring is made open, and I have represented
in Figures 1 and 4 two different manners by which it is emptied. This
is indispensable, because during the work a certain quantity of small
filaments detached from the thread accumulate on the end of the
traveller, see Figure 1, which would accumulate sufficiently into a mass
sufficient to break the thread by the increased friction upon the ring,
but as it will be easily understood when the traveller works under the
open ring no accumulation can take place, for each filament, so to say,
as it is taken up by the wire is thrown off through the open part of the
ring by centrifugal force. The same result may be arrived at by making
openings in the bar c corresponding to those in the ring 6, but I prefer
the other as the better method.
Having now described and particularly set forth the nature of the said
Invention, and the manner of carrying the same into effect, I would
have it understood that what I claim is, the method and means herein
indicated of making openings in the ring or arm on which the ring is
fastened for the purpose of preventing the clogging of the traveller or
ring by accumulating fibres.
In witness whereof, I, the said Henry A. Chapin, have hereunto set
my hand and scal, this Thirty-first day of October, in the year of
our Lord One thousand eight hundred and seventy-four.
