This invention relates to thread. boards for
spinning frames, and it aims to devise a rhecha~
ously preparatory to the do?ing operation, and to
nism of this character which will be exception
tions simultaneously when domng has been com
pleted. The present invention provides in a very
simple fashionfor accomplishing these results. .
In the particular construction shown in the‘
drawings, the thread board is made in sections
individual to the respective sections of the spin
ally simple in construction, economical to manu
facture,,c0nvenient to use, and of such a nature
that it will remain substantially free from ac
cumulations of lint and fly and will therefore
rarely, if ever, require cleaning.
The nature of the invention will be readily un
derstood from the following ‘description when
read in connection with the accompanying draw_
ings, and the novel features will be particularly
pointed out in the appended claims.
