page_text: We, WILLIAM CURTLIN CULVER, of No. 117 Ocean Avenue, Jersey City, in the
County of Hudson and State of New Jersey, Civil Engineer, and WILLIAM DENISON
CULVER, of No. 12 West 103rd Street in the City, County and State of New York,
Surveyor, both in the United States of America, do hereby declare the nature of
this invention to be as follows:-
The interior of a bowl in a tobacco pipe is liable to become coated with the ashes
and other materials in smoking tobacco, and difficulty has been experienced in
properly removing the objectional deposit, and in addition to this the interior of
such pipe bowl sometimes becomes partially disintegrated and requires scraping
and cleaning.
The object of the present invention is to provide a cleaning scraper that can be
expanded more or less according to the size of the tobacco pipe bowl, and such
scraper is easily and cheaply constructed and can be carried in the pocket.
We make use of two curved arms pivotted together and having a cutting edge
or edges upon the exterior surfaces of such arms, so that the cleaner can be
expanded or contracted to suit the size of the bowl, and when introduced into such
bowl and expanded the rotation of the bowl upon the cleaner or of the cleaner
within the bowl causes the edges to cut or scrape the interior surface of the pipe
bowl to remove adhering substances and clean the bowl.
We usually make the curved arms out of sheet metal and form a scraper or
cutter at the outer edge of each arm by bending over the edge of the sheet metal,
and a suitable clamping device is employed for holding the arms in the proper
relative position when they have been expanded to coincide with the interior of
the bowl, and it is advantageous to slot the curved arms and pass through the slots
a bolt with a thumb nut, by which the arms are held firmly in their proper relative
positions while being applied within the pipe bowl for scraping and cleaning the
same.
This pipe cleaner being expansible is easily adapted to different sized bowls,
and it can be used to scrape and clean the interior of the bowl without risk of
breaking or injuring such bowl as sometimes occurs when a rigid scraper is made
use of.

We, WILLIAM CURTLIN CULVER, of No. 117 Ocean Avenue, Jersey City, in the
County of Hudson and State of New Jersey, Civil Engineer, and WILLIAM DENISON
CULVER, of No. 12 West 103rd Street in the City, County and State of New York,
Surveyor, both in the United States of America, do hereby declare the nature of
this invention and in what manner the same is to he performed, to be particularly
described and ascertained in and by the following statement:-
The interior of the bowl in a tobacco pipe is liable to become coated with the ashes
and other materials in smoking tobacco and difficulty has been experienced in
properly removing the objectional deposit, and in addition to this the interior of
such pipe bowl sometimes becomes partially disintegrated and requires scraping
and cleaning.
The object of the present invention is to provide a cleaning scraper that can be
expanded more or less according to the size of the tobacco pipe bowl, and such
scraper is easily and cheaply constructed and can be carried in the pocket.
We make use of two curved arms pivotted together and having a cutting edge
or edges upon the exterior surfaces of such arms, so that the cleaner can be
expanded or contracted to suit the size of the bowl and when introduced into such
bowl and expanded, the rotation of the bowl upon the cleaner, or of the cleaner
within the bowl, causes the edges to cut or scrape the interior surface of the pipe
bowl to remove adhering substances and clean the bowl.
We usually make the curved arms out of sheet metal and form a scraper or
cutter at the outer edge of each arm by bending over the edge of the sheet metal,
and a suitable clamping device is employed for holding the arms in the proper
relative position when they have been expanded to coincide with the interior of
the bowl, and it is advantageous to slot the curved arins and pass through the slots
a bolt with a thumb, nut by which the arms are held firmly in their proper relative
positions, while being applied within the pipe bowl for scraping and cleaning the
same.
This pipe cleaner being expansible is easily adapted to different sized bowls,
and it can be used to scrape and clean the interior of the bowl without risk of
breaking or injuring such bowl as sometimes occurs when a rigid scraper is made
use of.
In the drawings, Figure 1 represents the cleaner as introduced within the pipe
bowl, and Fig. 2 is a plan view representing the cutting edges of the cleaning
arms as projecting.
The two curved arms A A are pivoted together at B, and the swinging ends of
the arms advantageously lap one upon the other, and the configuration of the arms
is such as to be adapted to the curved interior surface of the ordinary pipe bowl,
and by spreading such arms farther apart or contracting them, the cleaner is
adapted to different sizes of pipe-bowls.
There is a cutting edge at C at one side of the exterior edge of one of the arms,
and it is usually preferable to employ similar cutting edges on both arms, as
at C C, and each cutting edge is curved and it may project similar to a narrow
curved knife-edge, as shown in Fig. 2, so that it acts to the best advantage in
scaling off and cutting away any materials that may adhere to the interior surface
of the pipe, but such cutting edge may be narrow and formed upon the edge of
the arm.
This cleaning implement is cheap to construct and it occupies but little space
in the pocket and is readily adapted to use within the bowl of the tobacco-pipe
whenever necessary.

page_text: The clamp-screw D, passing through slots in the curved arms that cross each
other, serves to hold the parts firmly while in use. The position of the pipe is
indicated by dotted lines in Fig. 1.
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:
First. The expansible tool for cleaning pipe-bowls composed of two arms
pivoted together at their ends and having cutting edges adjacent to the pivot and
extending along the outer edges of the arms, the free ends of such arms forming
handles for manipulating the tool, substantially as set forth.
Second. The tool for cleaning pipe-bowls, composed of two slotted arms pivoted
together and having cutting edges at the exterior curved edges of the arms and a
clamp screw passed through the slots, substantially as set forth.
