Improvements in and connected with Nap-raising and similar
Machines.
I, WILLIAM HOLLAND of Allum Street, Ancoats, Manchester in the County of
Lancaster, Finisher and Calenderer, do hereby declare the nature of this invention
to be as follows:-
In nap raising machines and other machines of a similar type, there is usually,
after some little use, an accumulation of fly or fluff which is highly combustible
and frequently becomes ignited by accident, and it is the object of my invention to
prevent this risk and at the same time to provide means for extinguishing promptly
any fire which may originate in or be communicated to the machine. In many
instances however only the means for extinguishing fire will be employed.
According to my invention, I substitute the central or main shaft of the machine
by a hollow perforated shaft which is connected with a source of high pressure
steain or water supply and may also be connected with a fan blower or the like.
In use,
if a fire should occur the steam or water is turned on by the attendant,
whereupon the machine and its surroundings are immediately suffused with steam
or with water spray from the perforations of the hollow shaft and the fire is thereby
immediately put out. If the hollow perforated shaft be also connected with a fau
or blower, the current of air therefrom may be permitted to pass through the
perforated shaft whilst the machine is in use and thus blow away the fly or fluff as
it is produced to some extent.

1, WILLIAM HOLLAND of Allum Street, Ancoats, Manchester in the County of
Lancaster, Finisher and Calenderer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
"
or
In nap raising machines and other machines of a similar type, there is usually,
"fluff" which is highly
after some little use, an accumulation of "Hy
combustible and which frequently becomes ignited by accident, and it is the object
of this invention to prevent this risk or minimise it.
According to my invention, 1 substitute the central or main shaft of the machine
by a hollow perforated shaft which is connected with a source of high pressure
steam or water, and which may also be connected with a fan or blower. In use, if
a fire should occur, the steam or water is turned on by the attendant, whereupon
the machine and its surroundings are immediately suffused with the steam or with

page_text: water spray, and the fire is extinguished. If the hollow perforated shaft be also
connected with a fan or blower, the current of air therefrom may be permitted to
pass through the perforations whilst the machine is in use and thus blow away the
fly or fluff as it is produced, to a large extent.
The accompanying drawings illustrate in what manner I may carry my invention
into practical effect, and shew it as applied to a nap raising machine.
Figure 1 is an end elevation, and
Figure 2 a partial sectional plan.
Figure 3 illustrates a device by means of which the steam, water, or air supply
may be connected to the central perforated shaft when required.
A is the framing of the machine, B B the raising rollers, and C C pulleys for
driving the rollers B, all of which parts are of known construction as are also
the discs D or their equivalent arms on which the rollers have their bearings.
The discs or arms D instead of being mounted as usual upon a solid shaft, are
mounted upon the hollow shaft E, the surface of which between the discs D is
perforated so as to allow the escape of the steam water or air from the hollow
shaft in jets or spray.
It is preferred that this shaft should be closed at one end and be provided at
the other end with a packed joint F which will permit the shaft to rotate without
the contents escaping, when it is connected with the steam water or air supply
pipes. This joint may be connected with a breeches pipe G, one limb of which's
may be connected with a steam or water supply, and the other, a, with a fan or
blower supplying air under pressure. Each of the branches can also be closed by
a valve as.
When the machine is at work, the valve a¹ is open and s¹ is closed, consequently
air is admitted. Should a fire occur a' is closed and s' is opened, whereupon steam
or water rushes out through the perforations in the hollow shaft and extinguishes
the fire at once. The valves a¹ and s¹ may be geared together so that the closing
of one opens the other and both cannot be open at the same time.
If, as will frequently be the case, it is not desired to have an air supply during
work to blow away the fluff, the branch a and valve a¹ may be omitted.
The device illustrated in Figure 3 is for keeping the supply pipe G out of
contact with the perforated shaft E until it is actually required. A bracket His
secured to the frame of the machine and carries movably through its upper end the
supply pipe G. The end of this pipe is coned as shewn and the end of the shaft E is
formed with a corresponding seat. A disc or the like I is fastened to the end of the
pipe G and between this disc and the bracket II is a spring K which tends to force
the end of the pipe G into contact with the end of the perforated shaft. They
are held apart however by an excentric extension L from the handle of the
valve which bears against a projection from the bracket H. Upon a fire
occuring the attendant moves the valve handle in the direction indicated by the
arrow thus opening the water or steam supply and allowing the spring K to force
the end of the pipe G into communication with the shaft E. Upon the fire being
extinguished the water or steam supply is cut off and the parts are returned to
their separated positions shewn in the drawings.
It may also be arranged that the steam or water supply is connected automatically
by known devices actuated by heat arising from the fire as in "automatic
sprinklers." If the air and the steam and water supply be both used, they may
be connected respectively to opposite ends of the hollow shaft.
My invention may, in a similar manner, be applied to other machines of a similar
type for similar
purposes.
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:-
