Improvements in Inhalers.
I, THOMAS CHRISTY, Merchant, of 25 Lime Street, London, E.C. do hereby
declare the nature of this invention to be as follows:-
Improvements in inhalers, part being a communication from H. D. Cushman of
Three Rivers, Michigan, U.S.A. who took a Patent for a certain new & useful
inhaler No. 184 5th Jan. 1886 which has been transferred to Thomas Christy
aforesaid and registered at the Patent Office, London, on the 21st April 1892.
This invention consists of a metal tube open at both ends & smaller at one end
than the other and with small holes. In this tube I place menthol crystals sub-
stantially as set forth in Letters Patent No. 184, 1886. I then close the tube by
means of a metal cap, preferably with a projecting rim, I take a case open at both
ends, & this forms a sleeve into which the tube containing the menthol is slipped,
an indentation being made in both tubes for a guide & stop. In use the inhaler
can be pulled out from the inner case.
I also employ a hollow casing or tube for an inhaler open at both ends. The
menthol may be retained in position by inserting a perforated disc or by cotton
wool & cork if desired & re-charged at will.
I employ the sleeve as an inhaler open at both ends, the position of the medicated
charge be it menthol or medicated matter may be controlled in the tube & which
can be recharged at will as previously described in the Patent referred to.
Dated this 12th day of May 1892.
THO. CHRISTY.

Improvements in Inhalers.
1, THOMAS CHRISTY of 25 Lime Street London in the County of Middlesex,
Merchant 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, part being a communication from H. D. Cushman of Three
Rivers Michigan U.S.A. who took a Patent for a certain new and improved inhaler
No. 184 5th Jan. 1886 which has been transferred to Thomas Christy aforesaid and
registered at the Patent Office London on the 21st April 1892:-
This invention consists of a metal tube open at both ends smaller at one end than
the other & with small holes, or the tube may be of glass, hard rubber or suitable
material open at both ends. In this tube I place menthol crystals substantially as
set forth in Letters Patent No. 184, 1886. I then close the tube by means of a
metal cap preferably with a projecting rim. I take a case open at both ends &
this forms a sleeve into which the tube containing the menthol is slipped, an
indentation being made in both tubes for a guide & stop. In use the inhaler can be
pulled out from the inner case, or instead of making use of an indentation for a
guide stop I can employ pins secured diametrically in the casing or I can employ
a rotating screw threaded sleeve in which by the rotation of the sleeve the casing
is opened or closed at will at both ends so that when opened air will pass through
from end to end and carry the mentholised air to be inhaled in the usual way &
when closed the menthol will be protected. I also employ the hollow casing or
tube for an inhaler open at both ends. The menthol may be retained in position by -
TD021

page_text: inserting a perforated disc or by cotton wool and cork if desired and recharged at
will. I employ the sleeve as an inhaler open at both ends; the position of the
medicated charge be it menthol or medicated matter may be controlled in the
tube & which can be recharged at will as previously described in the Patent
referred to.
Plate I. Referring to the letters on the drawing A indicates a casing which may
be of glass, metal, hard rubber, or any other suitable material open at both ends,
B indicates a longitudinally sliding sleeve adapted to move a short distance
telescopically within the casing & by such movement to open or close the end
opening in the casing and the end opening in the sleeve itself so as to make passages 1
through the inhaler and through the medicament contained within the sleeve for
inhalation.
C indicates pins secured diametrically in the casing & D indicates longitudinal
slots in the sleeve through which the pins pass. These pins serve as guides & stops to
limit the longitudinal movement of the sleeves. In all the figures E indicates a 1
perforated stopper which may be of any usual kind, for example a perforated or
reticulated metallic support, as illustrated, or a perforated cylinder or strip to partly
close the perforations 1 in the sleeves to prevent the escape of menthol. K indicates
perforations in the end of the casing and L indicates perforations in the end of the
sliding sleeve, which latter perforations are not coincident with the former so that a
when the sleeve is pressed into the casing as in Fig. 1 and 3 all these perforations
will be closed & no air will be admitted into the inhaler but when the sleeve is slid
out as in Fig. 2, all these perforations are open so that air can be admitted into the
inhaler.
Referring to Fig. 2 M indicates an opening in the casing & N a solid part of the
end of the sliding sleeve adapted to fit & stop said openings. O indicates
perforations in the end of the sleeve, which as well as the holes in the casing are
open, as will be understood, whenever the sleeve is slid outwardly. The stops which
I employ prevent the sleeve from being drawn out too far and it cannot be pushed
in too far because its end will bear against the end of the casing.
There are other formal modifications that might be made in my inhaler, by
which the principle of my improvement might be embodied which is by the
employment of a hollow casing open at both ends and a hollow sliding sleeve
adapted to contain medicament and also open at both ends, having limited
longitudinal movement within the casing & adapted by being slid out and in to
simultaneously open & close the ends of the casing so that the inhaler can be used
or shut up at will. Fig. 4 shews a male indentation in the sleeve working in a
female indentation in the hollow casing or tube. G is the female indentation.
CA is the male indentation.
Plate II. Referring to the accompanying drawing Fig. 1 is a longitudinal
section of another form of my inhaler. Fig. 1A is an end view of the sleeve.
Fig. 2 is a similar longitudinal section of a modified form in which the screw part
of the sleeve is outside of the casing. Fig. 3 is like Fig. 1 except as to details
explained below. Referring to Figs. 1 & 2 upon the drawing A indicates the
casing which is open at both ends and screw threaded at one end to receive what I
will call a sleeve. B also correspondingly screw threaded. C indicates opening in
the sleeve & D a thumb piece for rotating the sleeve to screw it in & out.
E indicates perforated stoppers within the sleeve & F indicates opening in the
opposite tapered end of the sleeve. In Fig. 1 these openings consist of slits.
When the sleeve in this instance is forced inward by screw action, the tapered part
between these slits are driven against the tapering open end of the casing and thus
closed tightly together. When the sleeve is rotated in the opposite direction, so
as to screw it back, the tapered strips formed at the slitted end of the sleeve will
by their resiliency separate from each other enough to open an air passage through
the inhaler.
There are various other formal modifications in which the substance of my
invention might be embodied its principle consisting in the employment of an open

page_text: ended casing & a screw threaded sleeve adapted to open & close both ends of the
inhaler simultaneously so as to prepare it for use or preserve its contents the
perforations X & Y will permit the air to pass through and are so small as to
prevent crystals from coming out when the sleeve is moved out. When it is moved
in both sets of perforations are closed. This is a very simple and excellent form of
my invention.
Plate III Fig. 1. A is the hollow casing or tube which can be employed as an
inhaler, C the cork & E the perforated disc which prevents the crystals entering
the mouth or nose. Fig. 2 B is the sleeve which can be employed as an inhaler.
C the cork & E the perforated disc. The distance between the corks regulates the
quantity of menthol in the tube. The menthol can be changed or the tube refilled
by removing these corks and adjusting them.
Having now particularly described the nature of my said improvement & in what
manner the same is applied I declare what I claim is
1. An inhaler composed of the combination of a hollow casing open at both ends
and a hollow sliding sleeve also open at both ends and nearly of the same length as
the casing, said sleeve adapted to contain medicament & to slide longitudinally
within the casing & by such movements to unstop the openings both in the sleeve
and in the casing at both ends & to close them in like manner, substantially as set
forth.
2. In an inhaler, the combination with a casing open at both ends, of a sleeve
also open at both ends, adapted to slide longitudinally with respect to the casing &
by such movement to open or close passages through the inhaler & stop mechanism
for limiting the movement of the sleeve with respect to the casing, substantially as
set forth.
3. In an inhaler the combination with a screw threaded casing open at both ends,
of a sleeve also open at both ends & screw-threaded and adapted to be rotated to
simultaneously unstop the opening in the casing & to close them, substantially as
set forth.
4. The utilisation of both the hollow casing & sleeve used separately as inhalers
substantially as set forth.
