Improvements in Tobacco Pipes and Cigar and Cigarette Holders.
I HENRY NOVRA 4 Burton Crescent St. Pancras London W.C., Artist, do.
hereby declare the nature of this invention to be as follows:-
My invention consists of a novel method of constructing a tobacco pipe or cigar
or cigarette holder which will prevent the accumulation of saliva and nicotine by
prenting the former flowing down to the tobacco.
My plan is to employ a valve either in the stem of the pipe or cigar or cigarette
holder or at the mouth of the same, which opens and closes automatically by the
inspiration or exhalation of the smoker.

Improvements in Tobacco Pipes and Cigar and Cigarette Holders.
I HENRY NOVRA, of 4 Burton Crescent, St. Pancras in the County London,.
Artist, 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 in constructing pipes, and cigar and cigarette holders in
such a manner that the condensed breath and saliva shall not be liable to run down
the stem of the pipe and come into contact with the tobacco.
By this invention the formation of nicotine is reduced to a minimum or entirely
prevented.
I propose to effect the above by fitting in the pipe cigar or cigarette holder a
valve, so that such valve shall open and close automatically by the inspiration and
exhalation of the smoker, thus allowing the smoke to be freely drawn into the
mouth, but preventing the condensed breath or saliva from flowing down through
the stem.
The accompanying drawing shews an example of how
be carried into effect.
In this drawing
Fig. 1 shews a longitudinal section of a pipe and

invention may
Fig. 2 is a transverse section of the valve detached and drawn to an enlarged.
scale.
a shews the stem of the pipe, 6 small tube, made of glass or other suitable
material, having its outer end c contracted, so as to leave a small hole at this end.
d shews a small rod, rounded at its lower end, so as to fit against the concave
portion of the aforesaid tube, which forms the valve seat. The upper end of the
tube bis pinched in at e, so as to prevent the rod 6 from being drawn right out
of the said tube. The tube b is screwed or otherwise fixed into the portion a¹ of
the stem a.
The action is as follows:-
.
Upon "drawing" the pipe, the rod d will rise automatically to the position
shewn in dotted lines at Fio 1 and anable the amako to 3030 freely into the

page_text: mouth. Upon ceasing to "draw" the rod d will fall (or he forced back by the
breath) into its normal position, thus closing the communication between the stem
of the pipe and the bowl.
I do not wish to confine myself to the particular form of valve shewn, or to the
position in which it is fixed in the pipe, as I may have any other suitable form of
valve to effect the same object, and may fix it in any suitable position.
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. The improvements in tobacco pipes and cigar and cigarette holders
substantially as and for the purpose set forth.
2. In improvements in pipes and cigar and cigarette holders, the employment
of a valve acting automatically by the inspiration and exhalation of the smoker,
for the purpose set forth.
