of this invention to be as follows:-
A short tubular guide to prevent double weft & fluffy yarn. The old thread
guide is more of the nature of an eye which is flush with the top board but the new
guide is risen an inch above the top board.

An Improved Thread Guide for the Top Board of Spinning Frames
Used in Spinning Woollen, Worsted, Cotton, Silk, Mohair, and
Alpaca Yarns.
We, GEORGE CAMILLE WAUD and HARTLEY PARKER, of Britannia Mills,
Bradford, in the County of York, Mohair, Alpaca and Worsted Spinners, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to certain improvements in the thread guides for the top
beard of spinning frames and has for its object the prevention of double weft and
what is known as fluffy yarn.
In spinning woollen, worsted, cotton, silk, mohair and alpaca yarns, ends are
liable to break down, the thread continues to pass through the top and bottom
rollers down on to the top board, travelling along, right or left, to the next thread,
it is then drawn in through the eye as at present constructed and spun with the
thread passing on to the bobbin, thus producing what is known as "double weft."
In spinning all fibres, but especially strong wools, mohair and alpaca, there is a
constant accumulation of kemps and fluffy material on the top board, such kemps
and fluffy material are drawn towards the yarn and amalgamated with it, thus
producing what is known as "fluffy yarn." The object of our invention is to prevent
the production of both these classes of defective yarn and thereby save much
trouble as regards the fabrics such defective yarns are woven into. Hitherto the
eyes in the top board have been constructed in such a manner as to offer facilities
for making bad yarn, they are level with the top of the board and slightly
concave.

page_text: We accomplish our object by constructing an eye for each thread in the form of
a guard, raised above the level of the top board, and we find, from experiments
with the class of fibres herein enumerated, that the guide answers best when raised
about one inch above the top board.
In describing our invention more in detail, reference is made to the accompanying
sheet of drawings, in which
Fig. 1 represents a side elevation of such portions of a spinning frame as are
required to show how our invention may be applied.
Fig. 2 is a front view of the same, and
Fig. 3 a plan of the top board with our improvement added thereto.
The front delivery rollers A. and B. are mounted and driven in the usual manner,
as are also the spindles C. The top board D. is hinged to the rail or bar E, and
to the said top board opposite to each pair of rollers A. and B. is secured a guide F.
for guiding the thread or yarn Y. delivered by the front rollers to the bobbin G.
on the spindle C.
Each guide F. extends some distance above the upper surface of the top board,
and is prepared with an opening H. through the entire length.
When the machine is in motion the front rollers A. and B. are continuously
delivering fibrous thread Y. should the thread be broken, the fibre may be collected
by one of the rollers, or delivered on to the top board, in the latter case there is a
liability of the thread of fibre being drawn to the right or left and combined with
the adjacent thread of yarn, thereby making yarn of double thickness, which is
obviated by constructing guides in accordance with our invention, the extension
above the top board D. preventing the loose and broken thread coming in contact
with that passing to the bobbin on the spindle.
When spinning strong fibres such as mohair and alpaca, a large proportion of the
kemps and fluffy fibre leave the yarn as it is travelling from the rollers A. and B.
to the guides F. and fall upon the top board, where they remain, the extended
portion of the guides above the top boards shield the threads of yarn, preventing
the kemps or fluffy material being drawn into contact with the thread passing
through the respective guides, and thereby producing defective yarn.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
The guides F. combined with the top board D, the said guides projecting above
the upper surface of the said board such a distance that, the threads of yarn
passing through the guides are protected from broken ends and any loose fibre that
may be upon the surface of the said top board coming in contact and combining
with the said threads.
