COMPLETE SPECIFICATION.
An Improved Smoking Pipe.
I, FERDINAND HOLBERG, of 1772 Madison Avenue, New York City, United
States of America, Broker, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to smoking pipes, and some of the objects of the in-
vention are to provide improvements in this class of devices by means of which
the pipe may be readily and thoroughly cleaned, and the stem thereof cleansed of
any impurities that may collect therein; and a further object of the invention
is to provide a device of this character, simple in construction and positive in
operation, and with these and other, objects in view the invention consists essen-
tially in the construction, combination and arrangement of parts, substantially
as hereinafter described in the following specification, and illustrated in the ac-
company drawings, in which:―
Fig. 1, is a central longitudinal section of a pipe provided with my improve-
ments;
Figs. 2 and 3 represent detail views of the tube or sleeve;
Fig. 4, is a side view of a modified form of construction;
Fig. 5 is a longitudinal central section of the bowl and stem chereof, and
Fig. 6 is a top plan view, showing the bowl and stem in section.
Similar characters of reference designate corresponding parts throughout the
several views.
Referring to the drawings, and particularly to the construction illustrated in
Figs. 1, 2 and 3 thereof, the reference letter A, designates a pipe preferably con-
structed as shown, having a stem provided with an enlarged central bore B, prefer-
ably extending beyond the opening 1), in the bottom of the bowl C of the pipe;
and the bore at the free end of the stem of the pipe is preferably enlarged and
provided with interior screwthreads, as shown in Fig. 1 of the drawings.
preferably provide an exteriorly screwthreaded tube or sleeve E, desirably
constructed with an annular shoulder or flange L, and removably secure said
sleeve in the screw-threaded end of the stem of the pipe; and a mouth piece F,
is preferably provided with an enlarged bore having interior screwthreads to con-
nect the mouthpiece upon the other end of said tube or sleeve, as clearly illus-
trated in Fig. 1 of the drawings.
The tube or sleeve E, is preferably provided with a spider G, Fig. 3, with
which is connected one end of a rod H, the other end of said rod, being preferably
provided with a disk K, adapted to rest in the extremity of the bore B of the stem
beyond the opening D, in the bottom of the bowl, as illustrated in Fig. 1.
The disk K, is preferably of the diameter of the bore 3 of the stem of the
pipe, so as to make a close fit, in order than when the sleeve or tube E, is dis-

page_text: connected from the extremity of the stem, the rod H, may be withdrawn through
the bore of the stem, causing the disk , to force out of the stem all impurities
or foreign matter, accumulated therein, as will be readily understood.
In Figs. 4, 5 and 6, of the drawings, is illustrated a modified form of the con-
struction herein before described, in which the pipe is preferably divided through
the longitudinal center thereof, into two halves or portions, as shown in Fig. 6,
and upon one portion is preferably formed a continuous-groove M, constructed
to receive a tongue or rib N, formed on or connected with the other portion to
make a tight joint or connection between the parts when the same are secured
together, as shown in Fig. 4, and the tongue N, is preferably formed of rubber or
other similar material, as shown in Fig. 6, of the drawings.
The portions or halves are preferably secured together by removable frustro-
conical rings or bands O, O' and P, preferably having screwthreaded connection
with the stem and bowl of the pipe, as shown in Figs. 4 and 5 and by means of
the construction of these bands the tighter the same are screwed upon the pipe,
the closer the parts will be forced together, thus insuring tight connection between
the portions of the pipe, as will be readily understood.
In this construction, the pipe Q is preferably provided with a bowl R, in the
usual manner, with which communicate the bore of the stem, as described in con-
nection with the construction shown in Fig. 1 of the drawings.
By means of this construction the pipe may be readily taken apart and cleaned,
thereby preventing the same from becoming strong or foul by continuous use as
will be readily appreciated.
The two halves or portions of the pipe being removably connected together by
incans of the metallic bands or rings 0, 01 and P, it is only necessary to move
these bands by unscrewing the same from off the stem and bowl of the pipe, where-
upon free access is afforded to the inner-most parts of the bowl and stem.
I do not confine myself to the specific construction, combination and arrange-
ment of parts herein shown and described, and I reserve the right to make all
such changes in and modifications of the same as come within the spirit and scope
of my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A smoking pipe provided with an enlarged bore, extending beyond the
opening of the board, a screwthreaded sleeve secured in the end of said stem, con-
structed to receive a mouth piece and a rod connected with said sleeve and carry-
ing a device for cleaning said stem.
.
2. A pipe provided with a stem having an enlarged bore extending beyond the
opening in the bottom of the bowl of the pipe, an exteriorly screwthreaded sleeve,
having screwthreaded connections with said stem, said sleeve having an interior
web or spider with a central opening, a rod provided with a disk, adapted to
rest in the extremity of said bore beyond said opening, the other end of said
rod being secured in the opening in said spider and a mouth piece secured on
said sleeve, whereby when said sleeve is disconnected and withdrawn, said disk,
will be drawn through said bore to cleanse the same.
3. A smoking pipe embodying two halves constructed to be removably held
together by frustro-conical bands upon the stem and bowl thereof, and a mouth
piece connected with the stem of the pipe, whereby the pipe may be cleansed
by disconnecting the halves thereof.
4. A smoking pipe provided with two halves or portions adapted to be re-
movably connected by bands or rings and a packing between said halves to afford
a tight connection when the parts are secured together.
5. A smoking pipe embodying two halves or portions one portion having con-
tinuous grooves or recesses along the divided edges thereof, and the other portion

page_text: having a packing tongue constructed to enter said grooves to insure tight con-
nection when said halves are secured together.
