[Communicated from abroad by ZENAS C. ELDRED, of the City of Jackson, in the
County of Jackson and State of Michigan, United States of America, Manufacturer.]
I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane in the County
of Middlesex, Fellow of the Institute of Patent Agents, 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 a new and improved centrifugal bolting reel as will be
fully hereinafter explained.
Fig. 1 is a vertical central longitudinal section of the reel, Fig. 2 is a vertical
transverse section on line xx Fig. 1.
The flyer of a centrifugal reel has usually been made in the form of a closed drum,
circular in cross section, and provided with longitudinal tangentially arranged blades
mounted upon the outer surface of the drum, and driven at such speed as to insure
that material being bolted should, by the action of the flyer, be driven against the
inner surface of the surrounding fabric in such manner that nearly the entire surface
of the fabric should be utilised.
Also, a centrifugal reel having a flyer composed of a series of narrow beater blades
mounted upon the peripheries of spiders, constituting an open or skeleton flyer, has
been combined with a series of tilting or oscillating elevators mounted in the heads of
the framework over which the bolting cloth is stretched, and adapted to have their
outer edges tilted into close proximity to the cloth while traversing the lower part of
their path to pick up material which had there accumulated, to carry it up with the
upward moving side of the reel and then to tilt inwards, thus discharging their loads
or portions of them upon the flyer.
This invention has for its object the construction of a reel which shall combine the
advantages of both the earlier forms, without being subject to the imperfections of
either.
Like letters of reference indicate like parts in all the figures.
A A, represents generally the frame work and casing. B, C, are the reel heads
provided respectively with hollow trunnions be mounted in bearings on the frame-
work. D D, are stay bolts connecting the reel heads. FF, are cloth rings mounted
upon the stay rods by means of interposed carriers ff.
The bolting cloth is indicated by the dotted line G.

page_text: It will be seen that there is a practically unbroken bolting surface around the entire
circumference of this bolting reel, by reason of the cloth rings being supported upon
carriers.
H, is the beater shaft driven by a band pulley h. II', ii, indicate a train of
gearing connecting the beater shaft H with one of the bolting reel trunnions b
whereby, when the machine is in operation, the beaters are driven at.a greater speed
than the bolting reel.
Under ordinary circumstances the relative speeds may be 20 to 25 revolutions per
minute for the bolting reel, and 60 to 100 for the flyer; but either or both of these
parts may be driven at a higher speed, should it be found desirable.
K is a feed hopper and k a worm, on the beater shaft. LL, are spider arms keyed
to the beater shaft.
M is an enclosing shell, circular in cross section and fitting closely the outer
peripheries of the spiders, to which it may be attached by rivetting, soldering or
otherwise, as shall be found convenient. 11, are drum heads which may be of wood but
are preferably of sheet metal serving to close tightly the ends of the drum.
longitudinal blades, ribs, or beaters attached to and carried by the drum. By
preference, they are of sheet metal, V-shaped and soldered by their edges to the drum,
the shell of which is made of galvanised iron.
m m, are
NN, are elevators pivotted upon the stay rods so as to oscillate thereon by arms or
hangers, nn, having eyes or loops which surround the stay rods and are provided
with projecting spurs, n', adapted to engage with the carriers of the cloth rings and
limit the extent to which the elevators can tilt towards the drum. The object of
using these stops is to prevent the elevators from swinging so far inwards towards the
drum as to be struck by the rapidly revolving blades m m. Thus a larger flyer can
be used running at a slower speed than would be possible if the elevators were allowed
to swing without restriction.
When the machine is in operation, the elevators assume positions such as are
indicated in fig. 2, and prevent undue accumulation of material in the bottom of the
reel, constantly carrying up material and pouring it upon the flyer, which throws it
off against the cloth, its centrifugal action being substantially the same as in ordinary
centrifugal reels, with the advantage that, owing to the surface of the drum being
continuous, nothing falls between the blades to the bottom of the reel; that there is
little or no tendency to draw in air currents through the trunnions; that the lower
part of the bolting reel cannot be unduly loaded; and that the material is distributed
with great uniformity against the entire inner surface of the cloth.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
In a bolting reel the combination of the inner drum provided with longitudinal
blades, the bolting cloth and the tilting elevators, substantially as set forth.
