WILLIAM THOMAS EMMOTT of Blackfriars in the Borough of Salford in the
County of Lancaster IMPROVEMENTS IN OR APPLICABLE TO RING SPINNING
FRAMES"
[communicated to him from abroad by Charles Verenet and Eugene
Appenzeller both of Mulhouse in the German Empire.]
These improvements have for their object, to wind the yarn at a constant angle
without the assistance of a moveable guide wire and to secure a
twist, and consist in
more uniforin
(1) Two different arrangements or systems of spindles permitting the use of a
fixed ring rail.
(2) A system or arrangement of superposed moderator rings such that while the
guide wire remains fixed, either that or the superposed moderator rings shall
always be in contact with the yarn at the winding level.
In the first arrangement with the fixed ring rail, the spindle is capable of motion
around its axis only and has formed in it above the collar two vertical and
deametrically opposite grooves in which are engaged two small projections formed
within a tube or sleeve which surrounds the spindle and which thus partakes of
the rotary motion of the spindle while it is free to slide thereon with a very small
amount of friction. The sleeve has formed on its enlarged lower portion a
circunferential groove within which are two roller guides, serving to govern or
maintain the position of the sleeve-The rollers turn freely upon two pivots carried
by an external support or supports fixed to a carrier which transmits to the sleeve
through the rollers its own upward or downward motion and at the same time
affords a solid support to the spindle the vibration of which is further prevented
by the collar in which the spindle bears. The carrier receives its motion in the
usual manner from a suitably shaped cam or other arrangement of building motion.
To prevent the lodgement of fluff or dust the carrier and guides may be surrounded
by light metallic casings.
In the alternative method the spindle is capable of vertical as well as of rotary
motion. In order to arrive at this result the wharve is supported above and below

page_text: in any convenient manner so that it may be constantly maintained in the same
horizontal position. The spindle is made to slide freely through the wharve and
has formed upon it a vertical groove or grooves or a flat, the wharve being
provided with a corresponding feather pin or projection so that the spindle shall
always receive the rotary motion of the wharve. In each of these alternative
arrangements the positions of the grooves and of the corresponding projections
may be reversed, that is to say the grooves may be formed within the sleeve or the
wharve as the case may be while the feather pins or projections may be attached
to the spindle.
In the second arrangement the moveable ring rail as ordinarily used has fixed
above it two or more superposed cleft rings concentric with the spindle and at
such a height or distance apart that in any determined distance between the guide
wire and the ring the upper cleft ring shall be in contact with the yarn in winding
the last turns, or at the highest winding point.
