    N° 22,871 A.D. 1902 (Under International Convention.) Date claimed for Patent under Patents Act, 7901C being date of first Foreign Application (in United States), 70th Apr., 1902 Date of Application (in the United Kingdom), Hth Oct, 1902 Accepted, 18th Dec., 1902 COMPLETE SPECIFICATION. “Improvements in Inhalers I, John Howard McCulloch, a citizen of the United States, residing at Newville in the County of Cumberland, State of Pennsylvania, U.S.A. Salesman, 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 5 following statement: My invention relates to an improvement in that class of instruments known as “ inhalers ” in which the mouth-tube or air-inlialing tube is fitted with a sponge or other suitable absorbent material supplied with medicament, this central tube communicating with two nose-tubes adapted to contain medicine 10 which, in connection with the medicine on the sponge, produces the desired effect. I am aware that it has been proposed to provide an inhaler composed of two side inhaling-tubes and a central tube, the latter open at both ends and com¬ municating with the side tubes, as shown, for example, in LTnited States Patent ] 5 No. 134,858, of January 14, 1873, granted to W. P. Crumb. The object of my invention, however, is to provide a simple device which can be readily carried in the vest-pocket, the mouthpiece being arranged to rotate with respect to the nasal tubes and when folded to lie between them. The invention therefore consists, primarily, of a medicator comprising side vq parallel nasal tubes and a rotatable mouth-tube communicating therewith. Secondly, it consists of a medicator having parallel side nasal tubes with projecting lower portions and a mouth-tube having projecting lower portions adapted to rotatably engage the said projecting lowrer portions. Again, it comprises the provision of openings in the walls of one or both of 25 the projecting lower portions of the mouth-tube adapted to be brought into registry with an opening or openings in one or both of the projecting lower portions of the nasal tubes whereby without trouble medicament can be supplied directly to the sponge in the mouth-tube. Finally, the invention consists in the matters hereinafter described, and 30 referred to in the appended claims. The invention is illustrated in the accompanying drawings, in which-— Figure 1 is an elevation, partly in section, of my improved medicator. Figure 2 represents an elbow and one of the side tubes in detail. Figure 3 represents in detail the mouth-tube. [Price 8c2.] *
