I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (a communication from
Edward Willson Creecy of Corcoran Building, Washington in the District of
Columbia, United States of America Gentleman) and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention embraces a double acting syringe with its application to cleaning
tobacco pipes, cigar holders, cigarette holders, and the like.
In the accompanying drawings:—
Figure 1 represents a double acting syringe.
Figure 2 the same forming part of the stem of a pipe.
Figure 3 a pipe having the syringe combined with its stem, and its bowl provided
with an opening (closed by a suitable plug) whereby liquid may be drawn in or
be discharged for the purpose of cleansing.
Figure 4 is a sectional view of a pipe having the improved attachment, the bowl
of the pipe being provided with a saliva drip cup and a removable plug to
facilitate emptying the drip cup and to allow the ingress and egress of liquid for
cleansing purposes.
Figure 5 is a portionally sectional view of a pipe the stem of which is
provided with the syringe attachment and has a socket in which a removable
bowl rests there being a projection which enters the centre of the bowl and through
which the smoke is drawn.
Figure 6 is a sectional view of a pipe stem and bowl the stem being provided
with the syringe attachment and with a plug in its lower end by which liquid
may be admitted without removing it entirely; the stem being also provided with
a screw threaded socket in which the bowl of the pipe rests and with a perforated
projection extending from the socket into the bowl.
Figure 7 is a sectional view of a stem for pipes cigar holders or cigarette holders,
consisting of telescoping syringe sections; and
Figure 8 is a side elevation partly in section of a cigar or cigarette holder with:
this invention applied. '

page_text: It is a great desideratum in articles in which tobacco is smoked that there be
rapid and cheap means of freeing those parts through which the smoke passes
from the accumulation of nicotine, dust, and small particles of tobacco.
Various means for this purpose have been devised among which may be
mentioned the removable plug or drip cup placed in the bottom of the bowl and
which is intended to receive drippings of saliva, or the nicotine which may be
formed in the pipe; but such device only accomplishes the cleaning of the parts
situated near the plug and does not remove the accumulation from the stem.
By the device now to be described all matter which accumulates in the pipe,
cigar holder, or cigarette holder may readily be removed by employing the same
as means for bringing into contact with one or all the parts of a smoking implement
any suitable liquid that will dissolve the impurities, such for example as alcohol
or the solution of an alkali &c.
In the drawings A represents the barrel of the syringe in which is arranged
a piston B having a hollow rod b and a head b¹ and by the moving up and down
(of which, and stopping the opening in the rod or that at the opposite end liquid
may be drawn in and be expelled.
The preferred application of the invention is in a stem for articles in which
tobacco is smoked. "The stem forms the barrel and contains the piston the rod of
which is provided with the longitudinal opening and allows the smoke to pass.
The most simple form of embodiment is shown in Figures 3 and 4 of the
drawings. In these figures A represents the hollow stem B the piston and C the
bowl. The upper end of the stem proper is closed by a cap a having a central
passage in which the tubular rod-portion b of the piston slides. At the lower
end of the tubular rod is the head 61 which fits snugly in the stem A so that when
the opening in the rod is closed and the head is moved back and forth liquid may
be drawn into and expelled from the pipe stem. By stopping at either end liquid
may be sucked in at the other; and by stopping either end after the liquid is
drawn in, it may be expelled from the other.
The head b' is made of any material which will not be affected by alkali or
other substance applied to clean the stem and is also preferably made of material
not affected by heat as for instance of asbestos so that after the pipe has been
cleaned the head may be removed and itself be cleaned by burning.
The upper end of the tubular rod b is provided with a mouth piece b² the
opening in which registers with the tube and forms a direct conduit for the
smoke.
The stem may be attached to the bowl of the pipe in any suitable manner as by
screw threads or by flexible plugs attached to the lower end. This latter form is
preferable because it enables the stem to be made and sold separately and be
applied to bowls of different sizes, sufficient compression of the elastic plug being
possible to insure fits.
In most cases it is not necessary, nor is it often advisable, that liquid be
introduced into the bowl proper or chamber in which the tobacco is burned; and
therefore in order to provide for the admission of liquid at such a point as to
facilitate the cleaning of all the conduits through which the smoke passes, and
these alone, the lower end of the bowl is provided with an opening in which is
placed a removable plug or a screw cap c. This cap may be of any convenient
form and when desired to admit liquid without removing the cap entirely from
the bowl the form shown in Figure 6 may be employed. In this form the screw
threaded portion which enters the bowl is made hollow and there are here holes c¹
reaching from the circumference to the interior in such position as to be exposed
when the cap is screwed out a short distance.
The cap may be placed at any place where it is desirable that liquid be admitted ;
for instance as in Figure 6 where the stem of the pipe is extended horizontally
nearly the whole width of the pipe bowl and the opening in which the plug rests
and through which the liquid is admitted is in the outer end of the stem. In this
form also, the upper end of the horizontal portion of the stem is provided with a

page_text: socket which may be screw-threaded on its interior face or be smooth as shown in
Figure 5.-and up through the middle of this socket d is a projection d¹ which is
tubular to allow the passage of the sınoke from the bowl D which is so formed
as to fit snugly into the socket and is provided with an opening in its bottom
through which the projection d passes.
.
Besides the advantage of the device for readily cleaning the pipe the invention
has another and that is the ability to increase the length of the stem by simply
drawing out the piston. When however it is desired to use the stem of one length
only, the screw cap a may be provided with a screw threaded socket a¹ and the
lower end of the mouth-piece have an externally reduced screw threaded portion b³
which can be secured in the socket.
A stem capable of being extended to any desired length may be made with a
series of hollow pistons one within another the innermost one being provided with
a protruding mouth piece and the top of each piston rod being provided with a
screw threaded cap having a socket into which enters the cap of the next smaller
piston all as shown in Figure 7.
It is obvious that the double acting syringe may be applied to many uses other
than as an attachment to a tobacco smoking device.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is :—
1. A double-acting syringe substantially as described.
2. A cleaning device constituting part of a tobacco smoking implement consisting
of the stem a portion of which is in the form of a piston whereby liquid may be
drawn in and expelled for the purpose of cleaning substantially as set forth.
3. A cleansing device constituting. part of a tobacco smoking implement and
consisting of a stem having an internal hollow portion provided with a piston
whereby passage for the smoke and means for sucking in and ejecting liquid are
formed substantially as described.
4. A cleaning device constituting part of a tobacco smoking implement and
consisting of a stem provided with an internal hollow portion bearing a piston
and having a mouth piece formed with or attached thereto substantially as
described.
