page_text: LETTERS PATENT to John Dodd of Oldham in the County of Lancaster,
Mechanical Engineer for an Invention of "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR SPINNING AND DOUBLING COTTON, WOOL, SILK AND
OTHER FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said John Dodd at the Office of
the Commissioners of Patents on the 12th September 1883.
JOHN DODD of Oldham in the County of Lancaster, Mechanical Engineer.
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING
COTTON WOOL, SILK AND OTHER FIBROUS MATERIAL.
The first part of my invention relates to and consists in apparatus by which the
spindles of spinning and doubling machines are retained within the tubes or
sockets in which they revolve.
In carrying this part of my Invention into effect I employ a stud the upper part
of which I form so as to project at times over the wharve or whorl or a collar
upon the spindle
The lower part of the said stud passes into an aperture formed in the bracket or
tube supporting the aforesaid spindle within which aperture the said stud may be
turned, for which purpose I form screw threads upon the said stud which screw
threads take into corresponding screw threads formed within the aforesaid bracket
or tube, the, said screw threads permit the stud aforesaid to be turned while at
the same time they prevent the said stud from being withdrawn from the bracket
or tube above mentioned; or I secure the said stud within the bracket or tube
aforesaid by rivetting or in any convenient manner
Upon the stud aforesaid I form a collar or flange against which presses a spring
secured to the bracket or tube above referred to, which spring serves to maintain
the stud in position for preventing the withdrawal of the spindle from its tube or
socket, or I form a flattened part upon the stud above referred to against which
flattened part the spring acts. The stud aforesaid I also provide with a finger or
projection constituting a handle by which the said stud may be turned and its
Price RdI

spindle above mentioned which spindle may thus be withdrawn from the tube or
socket above referred to,
The second part of my invention relates to arresting the motion of the spindles
of machinery used in spinning and doubling cotton wool silk and other fibrous
materials and consists in forming a groove around each of the footsteps by which
the spindles above named are supported.
When it is desired to arrest the motion of a spindle the band by which such
spindle is driven is transferred from the wharve or whorl upon the said spindle
to the groove around the footstep. Instead of forming the groove aforesaid around
the footstep I mount in some cases a wharve or whorl upon each of the footsteps
of the spindles aforesaid to receive the band removed from the wharve or whorl
upon the spindle when it is desired to arrest the motion of such spindle

IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SPINNING AND DOUBLING
COTTON WOOL SILK AND OTHER FIBROUS MATERIALS
My Invention relates to and consists in apparatus by which the spindles of
spinning and doubling machines are retained within the tubes or sockets in which
they revolve-In order that my invention may be properly understood and carried
into effect I will now proceed to describe the same reference being made to the
drawings hereunto annexed Fig 1. is a vertical side view of a spindle used for
spinning and doubling and the tube or bracket by which such spindle is
supported such figure being partially in section Fig: 2 is a plan of Fig 1-
Fig 3 is a view of a portion of Fig: 1 upon an enlarged scale and Fig: 4 is a plan
of Fig 3 with certain parts omitted to avoid confusion. I shall affix similar letters
of reference to corresponding parts throughout the whole series of Figures
At a is a tube or bracket ordinarily employed in spinning and doubling machines,
which supports the spindle band within which tube or bracket a the spindle b is
free to be rotated. Upon the spindle b is mounted the wharve or whorl c. At d
is a stud the upper part of which I form with a projecting part d' which may at
times be caused to project over the wharve or whorl c Upon the stud d I form a
collar or flange d² a portion of the circumference thereof from A to B I formed
flattened (see Figs 2 and 4) Upon the stud d I form a projecting part d³ which
passes into an aperture e formed in the tube or bracket a the lower end of such
aperture e being of increased diameter and by rivetting or in any other suitable
manner I enlarge the lower end d' of the part d³ of the stud d-At f is a spring
secured at one end by means of the screw g to the tube or bracket a the other end
of the spring f presses against the flattened portion A B of the collar or flange d³
and so retains it in position-The stud d I provide with a finger or projecting
part d' which finger or projecting part d³ constitutes a handle by which the stud d
may be rotated in the tube or bracket a but is prevented from being moved in a
longitudinal direction by the part d' and enlarged part d' which form collars
which prevent the longitudinal movement. In the position of the parts as shown
in the drawing the part d' projects over the wharve or whorl c thereby preventing
the spindle b from being withdrawn from the tube or bracket a but leaving such
spindle b free to be rotated within the tube or bracket a-I also form upon the
stud da flattened part C against which the spring f rests, when the finger or
projecting part d' is turned into the position indicated by the dotted lines D.-
When it is desired to remove the spindle b from the tube or bracket a the stud d
is turned on its vertical axis E F by means of the finger or projecting part d³.
The partial rotation of the stud d will cause the flattened part C of the collar or
flanged to be pressed upon by the spring f so that when the finger or projecting
part d' is turned into the position indicated by the dotted lines D (see Figs 2 and 4)
it will remain in such position-When it is desired to again secure the spindle b
from being withdrawn from the tube or bracket a the stud d is turned into the
position shown in the drawing when the part d' will again project above the
wharve or whorl c and the flattened portion A B of the collar or flange d' will be
pressed upon by the spring f and thereby retained in such position until the stud d
is turned with sufficient force to force back the spring f.
In some cases I secure the stud d within the tube or bracket a as shown in Fig 5.
To those parts which are similar in construction and action to those described in

page_text: reference to and shown in the previous figures-I shall affix the same letters of
reference as those previously affixed thereto-Upon the lower part d' of the stud d
I form screw threads which take into corresponding screw threads formed within
the tube or bracket a. The screw threads upon the part d' and within the tube or
bracket a permitting the stud d to be rotated while preventing it from being
withdrawn longitudinally
In order that the stud d may be rotated so as to pass the screw threads formed
upon the stud d into the screw threads formed within the tube or bracket a the
finger or projecting part d³ is formed of such length that it will not come into
contact with the tube or bracket a while being screwed into the tube or bracket a.
I have hereinbefore only described and shown the end of the stud d as
projecting over the wharve or whorl c of the spindle b for the purpose of preventing
the spindle b from being withdrawn longitudinally from the tube or bracket a but
I would have it understood that a separate collar or boss upon the spindle 6 may
be employed in conjunction with the projecting part of the stud d for the
purpose of preventing the spindle b from being withdrawn longitudinally from the
tube or bracket a.
In the second part of my provisional specification I described a method of
arresting the motion of the spindles of machinery used in spinning and doubling
cotton wool silk and other fibrous materials but I make no claim for such method
Having thus described and ascertained the nature of my said invention and the
manner in which the same is to be performed I desire it to be understood that
I claim as sécured to me under the above in part recited Letters Patent
'
The combination of the stud d and spring f constructed and acting substantially
in the manner and for the purposes hereinbefore described and shewn
21
In witness whereof. I the said John Dodd have hereunto set my hand and
seal this eleventh day of March in the year of our Lord one thousand eight
hundred and eighty four,
