I, WILLIAM HOPKINSON, of Bradford, in the County of York, Broker, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES," to be as
follows:-
This Invention relates, firstly, to means of working or operating the upper
nipping jaw employed in such machinery, and the improvement consists in
having the said top jaw attached to a slidable frame, which is operated or
raised and lowered by means of tappets or cams and springs in a similar
manner to that in which the lower jaw is now operated. The said tappets
or cams are fixed on the same shaft as the cams for working the lower jaw,
and are adjustable thereon so as to act at proper times on friction rollers.

formed or fixed on the said cam shaft.
Secondly, this Invention relates to a method of attaching the upper jaw to
the slidable frame, and in means of ready adjustment thereof to the bottom
jaw, and consists in having the said top jaw made of a T form or broad at its
upper edge, which is planed true at right angles to the direction of motion of
the said jaw, and having cross slots therein to receive T beaded bolts, by
which it is fixed to the planed surface of a square bar; this bar has a neck
at each end by which it is supported (and capable of adjustment) in brackets
attached to the slidable frame.
