Complete Specification Accepted, 4th May, 1889
We, HENRY SPRING, of 11 Market Place, Brigg, in the County of Lincolnshire,
Chemist, and ALGERNON KIRKHAM, of Broughton near Brigg in the County of
Lincolnshire, Farmer, do hereby declare the nature of this invention to be as
follows:-
This our invention relates to certain new and useful improvements in tobacco
pipes; and which invention has for its object, firstly to provide a pipe by means of
which the whole of the tobacco placed therein may be consumed without waste, and
secondly to prevent the juice or nicotine from clogging the thread upon the cap or
plug, hereinafter referred to.
Hitherto in pipes as at present in use, the tobacco at the bottom of the bowl soon
becomes moist and unpleasant to smoke. In this case the tobacco is never wholly
consumed and that which remains at the bottom of the bowl is usually thrown away
thus causing a certain amount of waste.
By this our invention the objections above referred to are entirely overcome in a
simple, neat and efficacious manner; and said invention consists essentially of a
pipe, the bowl of which is of hollow section throughout its length, and is provided
with a stem near its lower end in the usual way.
Said bowl is provided at its lower end with an outside screw thread which fits into
the inside thread of a suitable cap.
This said cap may be provided at its underside with a suitable projection or stopper
which is adapted to fit loosely into the upper part of the bowl.
If desired, said cap may be formed with a bayonet joint or other suitable means for
retaining it in place upon the bowl.
By this our invention when the tobacco in the bowl has been consumed to within a
short distance of the cap, said cap may be removed and the plng upon its underside
inserted into the bowl at the upper end. The pipe is now inverted, and a fresh supply
of tobacco is inserted into the lower end of the bowl, and which tobacco is in turn
removed to the upper part of the bowl.

page_text: Wo, HENRY SPHINO, of 11 Market Place, Brigg, in the County of Lincolnshire,
Chemist, and ALGERNON KIRKHAM of Broughton, near Brigg in the County of
Lincolnshire, Farinor, 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 our invention relates to certain new and useful improvements in tobacco pipes,
and which invention has for its object, firstly to provide a pipe by means of which
the whole of the tobacco placed therein may be consumed without waste, and secondly
to prevent the juice or nicotine from clogging the thread upon the cap, heroinafter
referred to.
Hitherto in pipes at present in use, the tobacco at the bottom of the bowl soon
becomes moist and unpleasant to smoke. In this case the tobacco is never wholly
consumed, and that which remains at the bottom of the bowl is usually thrown away,
thus causing a certain amount of waste.
By this our invention, the objections above referred to are entirely overcome in a
neat simple and officacious manner hereinafter described.
In the accompanying drawings, in which like letters of reference refer to like parts
in all the figures, Fig. 1. is a part sectional olevation of our improved tobacco pipe,
showing the screw-cap in place. Fig. 2. is a sectional elevation through the bowl of
the pipe, shewing an alternative form of cap in place. Fig. 3 is a top plan of the
screw-cap showing the interior thereof. Fig. 4. is a plan view of the alternative
form of cap, showing the interior thereof. Fig. 5. is an elevation of the alternative
form of cap. Fig. 6 is a plan view of the caps as shown in the other figures, but
showing the underside thereof.
Our improved pipe consists essentially of a bowl A which is of hollow section
throughout, and has the usual stem B. The bowl has at its lower end a screw-thread (
which fits a corresponding screw-thread D in the cap E. The cap E may have a
milled or roughened odge F and has a projection G which is of slightly smaller
diameter than the bore of tho bowl A, and which projection has a diametrical groove
or slot H.
In the alternative form of cup, the side of the recess is smooth, and said cap fits
over the diminished portion K of the bowl A. In the inside periphery of the cap
are two or more slots L which extends a short distance downwards and then horizontally
to right and left respectively. Projecting from the sides of the diminishod portion K
are two or more pins or projections M which, when the cap is placed upon the bowl
with the pins or projections entering the slots L will retain the cap in position when
it is slightly turned around, as will be readily understood.
By this our invention, when the tobacco in the bowl has been consumed to within
a short distance of the cap, the said cap may be removed by grasping the roughened
edge F, or by inserting the edge of a coin into the slot or groovo H und unscrewing,

page_text: or in the alternative form of cap, turning the cap slightly to the left. The projec-
tion G is now entered into the upper part of the bowl, as indicated by broken lines
in Fig. 1, and the pipe being inverted, a fresh supply of tobacco is inserted into the
lower end of the bowl. Thus it will be understood that it is not necessary to relight
the tobacco each time the pipe is refilled.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1st) The combination with a tobacco pipe having the bowl of hollow section
throughout, of the cap having an inside screw-thread adapted to fit a corresponding
screw-thread upon the lower end of the bowl, and having a milled or roughened
edge, and an underside projection with a diametrical slot or groove therethrough, all
substantially as and for the purposes hereinbefore set forth.
2nd) The combination with a tobacco pipe having the bowl of hollow section
throughout, of the alternative form of cap, having a recess with a plain side, wherein
are two or more slots extending vertically downwards and horizontally along the
side of said cap, and an underside projection having a diametrical groove or slot;
and of pins or projections projecting from the side of the lower and diminished end
of the bowl, whereby the aforesaid cap is retained in position, all substantially as
and for the purposes hereinbefore set forth.
