1 Claim. (G1. 128-186)
This invention relates to an inhaler designed
primarily for use in the treatment of pulmonary
diseases, one of the objects being to provide a

With the foregoíng and other objects in view
which will appear as the description proceeds, the
invention consists of certain novel details of con

indicated at C. When. the patient draws air
through the tube 15, While inhaling, fresh air is
pulled into the crooks |2 and |3 between the ?ared
ends thereof and the open ends of the supple

provided with a lid or cover 2 formed preferably
of soft rubber having a ?ange 3 for embracing

end for overlying the adjacent portions of the cap

into each crookV in proportion to'the fumes col
lected thereby from containersiß and 'l can be
easily regulated. For example by thrusting the
open ends of the crooks well down into the con
tainers 6 and 'I the proportion of fumes to air will 30
be much greater than where the open ends of the
crooks are adjusted upwardly away from the con
tainers 6 and 1. O'bviously, as the crooks are
separately adjustable the proportions of the fumes
from the respective receptacles 6 and 'l can be
varied. Furthermore as the tubes 9 are rotatably
as well as slidably mounted in the cap 2, it is a
simple matter to swing the crooks away from
positions over the supplemental containers 6 and
1 so as to permit medicaments to be placed readily
in the containers.
What is claimed is:
An inhaler including a main container having
a suction tube extending therefrom, a cap sealing
extending downwardly into the main container I'
the container and supporting the tube, supple
adjacent to the bottom thereof. The upper or
outer end portion of each tube is bent to form a
mental containers Within and supported by the
cap, tubes slidably and rotatably mounted within
the cap and extending into the main container
adjacent to the bottom thereof, and crooks at the
upper ends of said tubes and adjustable relative 50
to the respective supplemental containers for re
crook, the respective crooks being shown at I 2
50 and I S respectively.
The lower or inlet end of
each crook is slightly flared as shown and its over
all diameter is slightly less than the internal di
ameter of the adjacent supplemental container 6.
An outlet tube M extends through the cap 2
and has a suction tube 15 of rubber or the like
ceiving fumes therefrom and for receiving fresh
air sucked into the crooks, the inlet end of the
crooks being ?ared.
