Drain Cleansing Machine Head.
I, JOSEPH EPHRAIM, of 59, Pitfield Street, Hoxton, in the County of London,
Chimney Sweep and Drain Cleansing Machine Manufacturer, and Brass and
Iron Founder, 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 the construction of a drain cleansing machine head.
According to the invention I form the machine head with a spear pointed metal
end having a helical or screw blade, and I fix the said head to the rod section
carrying the brush or plunger by means of a joint of the kind described in my
Specification No. 7201 of 1897. Washers, preferably concave on their inner faces,
are provided for gripping the brush or plunger upon the reduced end of the said
section which is screw-threaded to allow of different sizes of brushes and plungers
being used as hereinafter described.
To enable my invention to be fully understood I will describe it by reference
to the accompanying drawing which is a sectional elevation of a drain cleansing
machine head constructed according to my invention.
a is the socket to which the handle of the machine is secured the said socket
being connected to the machine head by a joint b of the kind described in my
said application. c is the reduced end of the machine head section of the handle,
the said reduced end being screw threaded.
d is the spear pointed metal rod forming the machine head and e is the helical
screw formed thereon, the said screw being shewn in two parts. The inner end
of the said machine head d is provided with a screw-threaded hole to enable
the said head to be screwed upon the reduced end c of the machine head section

my said specification, the screw c being provided with a flat against which the set
screw of the joint can bear.
fis the brush, the said brush being secured upon the screw c by means of the
washers g, g on each side thereof which are caused to grip the brush when the
head d is screwed on to the screw c.
With this construction of drain cleansing machine head it will be obvious that
the brush can be easily replaced by a plunger or by a brush of a different
diameter.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A drain cleansing machine head comprising a spear pointed metal end
having a helical blade or screw upon its periphery and being screwed upon the
screw-threaded end of a section upon which the brush is mounted, substantially
as described and illustrated in the accompanying drawing.
2. The combination and arrangement of parts forming the improved drain
cleansing machine head hereinbefore described and illustrated in the accompany-
ing drawing.
