Date of Application, 17th Aug., 1895
Complete Specification Left, 17th June, 1896-Accepted, 25th July, 1893
I, WILLIAM SIMPSON of 338 Fairfield Road, Droylsden, in the County of
Lancaster, Manager, do hereby declare the nature of my said invention to be as
follows:-
My invention consists in the application of a filter to a smoking pipe, to filter the
smoke before it passes to the mouth of the smoker.
The filter is, by preference in the form of a sheath or sleeve of textile or similar
material, covering a perforated tubular stem or extension of the mouth-piece of the
pipe, and such perforated stem, with the sheath slid thereon after the manner of a
glove finger, is introduced into and occupies a position within the wide bore part of
the pipe stem connected with the bowl, and is so arranged that auy smoke drawn
from the bowl has of necessity to pass through the filter before it reaches the mouth
and thus effectually ensures of any nicotine or other objectionable matter carried!
by the smoke being intercepted.
Dated this 17th day of October 1895.

I, WILLIAM SIMPSON of 338 Fairfield Road, Droylsden, in the County of
Lancaster, Manager, 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 :-
My invention consists in the application of a filter as hereinafter described, to a
smoking or tobacco pipe, to filter the smoke before it passes to the mouth of the
smoker.
The filter is, by preference in the form of a sheath or sleeve of textile or similar
material, covering a perforated tubular stem or extension of the mouth-piece of
[Price 8d1

page_text: the pipe, and such perforated stem, with the sheath slid thereon, after the manner
of a glove finger, is introduced into and occupies a position within the wide bore
part of the pipe stem connected with the bowl, and is so arranged that any smoke
drawn from the bowl has of necessity to pass through the filter before it reaches the
mouth, and thus effectually ensures of any nicotine or other objectionable matter
carried by the smoke being intercepted.
And in order that my said invention shall be readily understood, reference is made
to the hereunto annexed drawings in which
Fig. 1 is a longitudinal section of a tobacco pipe with my improved filter applied
thereto.
Fig. 2 is a transverse sectional view of the pipe stem.
Figs. 3, 4 and 5 represent the parts of the improved pipe separately.
In accordance with my invention I affix to the mouth-piece (A) of the pipe, a
finely perforated tubular stem or extension (B) Over this stem I slide a sleeve
or sheath of textile or similar material (C), by preference tubular lamp wick or
plush, with one end closed. I then introduce such stem and sleeve into the wide
bore part (D) of the pipe stem, as illustrated in Fig. 1, the respective outside and
inside diameters of the sleeve (C) and stem (D) being, by preference, such as to
leave a slight space (E).
With the mouth-piece screwed home and the pipe in use, the smoke drawn from the
bowl (F) cannot reach the mouth of the smoker without first passing through the
sleeve (C) and stem (B), and the interstices of the material and stem being very
small, all nicotine is effectually arrested, and pure smoke only can pass forward.
The extended surface of the sleeve or filter and perforated stem, ensure of the smoke
being readily drawn into the mouth, and in no way impeded.
The sleeve or sheath (C) being, by preference, loosely fitted on to the stem (B)
(although if desired it may be solutioned on) can be easily removed, and a new and
clean sheath or filter substituted. This sleeve is more or less a fit on the stem so
as to retain its position, but if desired the open end may be gathered or drawn with
elastic cord to effectually attach it to the stem.
In lieu of a textile material, sponge or asbestos may be used for making the sleeve
or filter, but I prefer tubular lamp wick, or plush.
A wire gauze or finely woven stem may be substituted for the perforated stem.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I am aware of the specification of Wuterich's Patent No. 3199 of 1889, and
I make no claim to anything described and claimed therein, but I declare that
what I claim and desire to secure by Letters Patent is :-
1st. In tobacco pipes, the use of a "filter" within the stem, composed of a sleeve
or sheath of filtering material (C), mounted upon a perforated stem (B) or its
equivalent, as hereinbefore set forth and illustrated on the accompanying drawing.
