Improvements in the Feed Rollers of Fur Blowing, Fur Forming,
and similar Machines."
I, ROBERT. ROBINSON of Gee Cross, Hyde, in the County of Chester, Hat
Manufacturer, 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:-
My invention relates chiefly to the feed rollers of what are known as fur
blowers, and used in hat manufactories for separating the fur from its impurities,
and in which it has heretofore been the practice to employ finely grooved or fluted
rollers for drawing the fur from off a travelling apron, and feeding it into the
machine, or into one or other of its sections. With such rollers it has hitherto
been found that they require a great deal of attention to keep them in proper
working order, since owing to the small amount of surface which actually "nips
the fur, the roller does not effectually feed the shorter fur, or owing to the tendency
of the short fur to accumulate in the grooves (and so convert the rollers into
smooth faced rollers) it has been necessary to periodically clear such rollers
in order that they shall maintain their "nip" upon the fur, and especially the
shorter staples.
Now my invention has for its object to substitute a set of feed rollers which will
overcome the aforesaid objections, and therefore feed the fur more uniformly and
effectually and require no other attention than repair or replacement when worn
down, and my invention consists essentially in employing square, triangular or
similar coarse faced rollers and causing such rollers to so revolve as for the angle
(or corner) of one roller to come opposite to, or gear in unison with, the flat face
or side of the other roller.
And in order that my invention shall be clearly understood I have hereunto
annexed a sheet of drawings illustrating so much of the "feeding-in end" of a
fur blower as will suffice to make my improvements clear, and which differ
in no essential particular as applied to any other part of the blower, or equivalent
machine.
Figs. 1. 2. and 3 shew a set of feed rollers (A), (A) of square cross-section, and
the relative positions they occupy in three stages of their movement. Fig. 4 shews
a set of feed rollers (A), (A¹) of triangular cross section. In either a square
or triangular section the facits of the rollers are slightly hollowed out
longitudinally for the better revolving of each roller, and for the better grip on
the fur.
Both rollers are geared in the ordinary way by small pinions (not shewn), and
are therefore readily adjusted to rotate in opposite directions, and in a manner
which causes the angle of one roller to mesh with the face of the other as
illustrated more clearly in Figs. 1, and 2. Fig. 5 shews a modified form
of the square rollers, the surface of each facit being slightly undulated to give a
better hold or "nip on the fur. For this same purpose I may hollow out the
facits of the rollers shewn in Fig. 1. 2 and 3, in an irregular manner (as shewn by
the dotted lines (A2) in Fig. 1) and thereby cause the deeper part of the hollowing
to have a better "bite," or "reaching-in' effect on the fur, but I have found
in experimenting that the section of rollers shewn in Figs. 2 and 3 answers well
for all practical purposes.
Although shewn as applied to the feed-in end of a fur blower, my improved

page_text: rollers may be used for the various sections of the blower, and nay also be used
with fur formers and like machines, in lieu of finely fluted or grooved rollers.
Having thus particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed, I wish it to be understood
that what I claim and desire by Letters Patent is :-
1. The constructions of coarse faced feed rollers herein described and shewn on
the accompanying drawing, or their mere mechanical equivalent, mounted and
operating as and for the purposes set forth.
