COMPLETE SPECIFICATION.
An Improved Tube and Pipe Cleaner.
I, ALBERT JACKSON, of Barkly Street North Fitzroy, in the Colony of
Victoria, Nail 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 :-
This invention consists of an improved tube and pipe cleaner the scraping
medium of which is formed of a number of short lengths of tubularly and
obliquely arranged coiled steel wires whose ends are supported by being cast or
otherwise secured in end bosses carried by a central rod or bar. One of said
bosses is provided with a screwed socket to receive the usual hand rod whilst the
other boss is so arranged upon the central rod or bar that its position thereon can
be adjusted in order to compress the coiled wires and so bulge them outwards to
the requisite degree or size to suit the tube or pipe in which it is to be used.
The attached drawing illustrates my invention.
Fig. 1 is a side view, Fig. 2 a central section of the adjustable end,
Fig. 3 a section on line a a Fig. 1 and
Fig. 4 a section of the end which receives the hand rod.
The series of coiled wires A forming the cleaner are arranged about a spindle
or rod B which is preferably round and provided at one end with a screw coupling C
for attachment to the usual long hand rod the aforesaid lengths of coiled wire A
being cast or otherwise secured in end bosses or collars D and D1 and the coiled
wires are so placed as to lie obliquely to the central spindle B and be supported at
their ends only by said bosses or collars D and D1 and without being directly
attached to the spindle. The outer end of said spindle is threaded to receive an
adjusting and a lock nut b and b1 respectively in order that when the two collars
or bosses which support the series of oblique coiled wires are slipped on the spindle
the inner collar D1 will bear against the end of said coupling C and then by
placing the adjusting nut in position and screwing it up the collars will be forced
towards one another and the coils be bulged out or extended to the requisite
diameter. Also by the coiled wires being pliable they adjust themselves to suit
any variation in the size or form of the tube or pipe.
Although I have described the cleaner as being made on a round spindle it may
also be made on a square spindle and with the outer end furnished with a series
of holes through which to place a pin for adjusting purposes. Further the coils
may be made of wire either round or polygonal in section.
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,
1. In a tube or pipe cleaner a series of tubularly arranged coiled wires
supported obliquely between end bosses substantially as described and shewn.
2. A tube or pipe cleaner consisting of the series of coiled wires A carried
obliquely by end bosses D and D 1, the central rod B the socket C and the nuts b
and 1 substantially as described and shewn.
Dated this 8th day of May 1896.
