IMPRovEMEN-r IN iNHALERs.

Specification forming part of Letters Patent No. 179,970, dated July 18, 1,876; application tiled June 16, 1876.

a longitudinal section of the same. Fig. 3 is a modified form of the devices.

Like letters refer to like parts wherever they occur.

My invention relates to that class of apparatus termed inhalers and fumigators,77 used for the treatment of diseases of the air-pas sages, for disinfecting apartments, destroying vermin, and like purposes; and has for its object sucha construct-ion and arrangement of the several chambers and connecting-passages that the instrument, when charged with liquids, may be safely carried about the person, or packed and transported without liability of spilling theliquids or injuring the clothing or goods which may be in contact with it.

To this end I connect two or more com partments of an inhaler by a suitable tube or tubes, which extend into the compartments sufficiently far to form a stand-pipe in each compartment, thus preventing the escape of liquid from one compartment to another, no matter what position the inhaler may occupy; and I also extend the air-induction and the inhaling tubes for such a distance into the said compartments that, under all conditions, the liquid is confined to the respective chambers. I thus, by an arrangement of passages with relation to the chambers, secure a free passage and escape for gas or aeriform matters, and hinder the escape of liquids.

I will now proceed to describe my invention, so that others skilled in the art to which it appertains may apply the same.

In the drawing, A A indicate a series of connected receptacles, chambers, or compart-` ments, which may be formed separately and secured together, or by dividing up a tube by means of partitions; but in either case the communication between the compartments is established by means of tubes al a, which pass through the lpartitions and extend beyond the same, so as to form cups or stand-pipes that prevent the escape of liquid. In connection with said compartments, tubes b c are employed, as usual, for establishing communication With the exterior of the chamber. These tubes b c I .prolong or extend within the chambers,'as shown at b c', so as, in turn, to form cups or stand-pipes, which preclude the escape of the liquid.

Figs. l and 2 show the preferred shape' of my devices, and the literal construction thereof may be described as follows: Each compartment is a bulb, formed of glass with two necks, closed by Stoppers perforated for the passage of a tube of glass, and provided with a coupling of metal, or hard rubber, if preferred. Two or more such chambers may then be connected, as shown, by a tube which extends to near the center of each chamber, and

the inhaling-tube and air-inlet tubes then in-' serted through corks, which close the free necks of the bulbs. In the modification a cylinder is used, and the chamber formed by partitions, though which pass centrally glass tubes, in the manner and for the purposes before specified. p

Aqua ammonia and an acid are generally employed with this class of devices, and the operation will be described therewith: The Stoppers which close the free ends of the receptacles beingv removed, an acid is placed in one chamber and aqua ammonia in the other. The Stoppers are 'then replaced, and upon either drawing or forcing a current of air through the tubes, the vapors from one chamber are carried into the other, and the vapors of the two, uniting, form ammoniacal fumes, which may be used in the treatment of disease or for other purposes, or may be made the vehicle for ad ministering other drugs.

Though a free passage exists for vapors, it will be apparent that therelation of the tubes is such that no liquid can escape, and consequently, when not in use, the instrument may' be safely carried in the pocket without ren1oving the liquids with which. it is charged.

It sometimes happens that, in addition to the use of amlnoniacal vapors or carbolatedv vapors, it is desirable to use other medicaments, or the vapors of three or more drugs \\'hich.do not combine, or of which two or more cannot be placed in one receptacle, in which case the advantages of the construction shown in Figs. l and 2 will be apparent, as a bulb maybe added, so as to increase the series to any desired number, and this Without the exercise of mechanical skill, and without loss of time or injury to the appearance of the article.

If' desirable, two or more of the bulbs may be blown with connecting-necks.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In an inhaler or fulnigator havingr an induction and eduction tube, the combination ot' two liquid receptacles or chambers, connected by a tube common to both, said tube extending into each chamber for a distance slightly' less than halt' the length of the chamber, and

I in opposite ends to the induction and eduction tubes, substantially as and for the purpose specin'ed. Y

2. In an inhaler or fumigator having an iuduotion and eduction tube, which extend into their respective chambers, the combination of two liquid-receptacles, connected by a straight tubecommon to both, said tube extending i11- to each receptacle, substantially as and for the purpose specified 3. An inbaier or fumigator composed of a series of globular chambers, counectedby a straight tube or tubes, c, substantially as and for the purpose specified.

In testimony whereof I, the said ROBERT L. STEEN, have hereunto set inyhand.
