1 Claim. (Cl. 15-104.30)
This invention relates to pipe cleaners and throughout its length with alternately arranged
has for an object to provide a device of this
character Which may be conveniently used to
clear clogged drains of sinks, toilets, bath tubs,
5 lavatories, and the like, without the use of a
plunger or without removing any part of the
A further object of the invention is to provide
a device of this character which will consist
10 of a flexible coil of barbed wire provided at one
end with a handle and at the opposite end
with a hook, the coil being provided throughout
its length with alternately arranged barbs and
brushes which project beyond the coil for con
l Ul tact with the surface of the part being cleaned.
A further object is to provide a device of
this character which will be formed of a few
strong simple and durable parts, which will be
inexpensive to manufacture, and which will not
20 easily get out of order.
With the above and other objects in view the
invention consists of certain novel details of
construction and combinations of parts herein
after fully described and claimed, it being under
stood that various modifications may be resorted
to within the scope of the appended claim with
out departing from the spirit or sacrificing any
of the advantages of the invention.
In the accompanying drawing forming part
30 of this speciñcation,
Figure l is a perspective view of a pipe cleaner
constructed in accordance with the invention.
barbs II and bristles I2 clamped in place be
tween a twist of the barb wire. One end of the
coil is provided with a hook I3 forming a pene
trating terminal for Working through a clogged
up portion of a pipe when the coil is` twisted
and forced into the pipe in the conventional
The opposite end of the coil is free from barbs
and bristles and forms a shank I4 having an 10
eye I5 on the end to receive the intermediate
portion of a handle I6 which is disposed trans
versely of the barb wire coil.
In use the hooked leading end of the pipe

therein, the flexibility of the coil permitting the
same to conform to the contour of curves in the
pipe during the cleaning operation.
will be fully understood without further explana
tion, except that while the device is shown of
a certain length in the drawing it will be under
stood that it may be made any length.
What is claimed ís:
A pipe cleaner for clearing clogged drains
Figure 2 is an enlarged view of a portion of
comprising a ilexible helical coil of barb Wire,
the barb wire coil showing the arrangement of
barbs and brushes.
Referring now to the drawing in which like
characters of reference designate similar parts
in the various views, I0 designates a flexible
between adjacent barbs, o-ne end of the coil
being free from barbs, and a handle disposed
on the said end of the coil.
helical coil of conventional barb wire provided
The barbs and brushes contact with the sur
face of the part being cleaned and effectively
scrape and scour all clogging material there
From the above description it is thought that
the construction and operation of the invention
bristles clamped in the coil at points spaced
