Improvements in Tobacco Pipe Cleaners.
I, JOHN JACOB SNYDER of 206 La Salle Street Washington District of
Columbia United States of America Manufacturer 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 :-
My invention relates to tobacco pipe cleaners; and its novelty will be understood
from the following description and claim when taken with the drawing in which:
Figure 1, is a perspective view of the cleaner connected to a pipe bowl.
Figure 2, is a vertical section.
Figures 3, and 4, are detail views of parts.
Figure 5, is a view of a modified construction.
Figure 6, is a similar view of another modification.
Referring by letter to the drawing: A, indicates a pipe having a bowl a, and
stem, and B, indicates the pump of the cleaner. This pump B, is formed with the
cylinder c, having the removable cap d, and the piston e, having the rod f,
extending through an aperture g, in cap d, and provided with a handle h, as
illustrated. The pump cylinder c, is fixedly connected to a plate i, and this plate
is provided with a nipple j, designed to hold the gasket or washer C, against casual
displacement.
D, indicates the yoke. This yoke has its branches passed through apertures 1,
in the plate i, and threaded for the engagement of nuts m, and it is provided with
the apertured cushion n, of leather, which is designed to bear against the bowl
bottom and prevent scratching of the same, and is also designed to permit of the
gasket or washer C, being tightly clamped upon the top of the pipe bowl without
danger of breaking the same.
In order to prevent peculiar shaped bowls from slipping from between the
gasket C, and cushion n, I employ the concavo convex and annular keeper E. This
keeper ring E, which is formed of leather, is slipped over the pipe stem and
surrounds the lower end of the bowl as shown.
In Figure 5, I show a modification in which a yoke D¹, is formed by a plate i¹,
threaded legs k', depending from said plate, and a base plate F, designed to be
adjusted by nuts m, and is provided with a cushion seat p, to receive lower end of
pipe bowl.
When this construction is employed the cushion n, shown in
Figures 1, 2, 4, may be dispensed with but the keeper E, may be employed if
necessary.
In Figure 6, is shown a construction in which a yoke frame is formed by a
plate, legs or side bars 2, and a base plate F', and in which the pump is clamped
to the pipe bowl through the medium of a screw taking through a threaded aperture
in plate F', and provided with a swivelled and cushioned head r. This head r, is
designed to bear against the bottom of the pipe bowl, and when necessary, the
keeper ring E, may be used.
It will be observed that all of the several constructions disclosed for connecting
the
pump and
pipe bowl, are clamps, and I would have it understood that I may
employ any suitable construction of clamp.
In use the pump is clamped on the pipe bowl. The pipe stem is then in..tersed
in some suitable cleansing liquid and the pump piston is reciprocated when the
liquid will be alternately drawn and forced through the entire stem and bowl of
pipe and the same will be quickly cleared of sediment.

page_text: 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:
A pipe cleaner comprising a pump having a plate at one end and a gasket
adapted to bear upon the edge of a pipe bowl, an adjustable yoke connected to the
plate and adapted to receive a pipe bowl, a cushion carried by the yoke and adapted
to bear against the underside of a pipe, and an annular concavo-convex keeper
adapted to receive the stem of a pipe and surround the lower end of the bowl,
substantially as specified.
Dated the 4th day of February 1896.
