    Emersons New or Improved Invalid or Siphon Drinking Cup. means of the finger is shewn on one side of and near to the handle of the cup. Figure 2 is a horizontal section of Figure 1 taken on the line A, B; Figure 3 is a vertical section of a siphon drinking cup, according to my Invention, having an opening at the top of the siphon pipe which may be closed by the finger of the patient or of the person administering the contents of the cup. 5 In this Figure the mouth of the siphon pipe is curved outwards. Figure 4 exhibits the siphon arrangement in which the air channel is made to communicate at the upper end of the siphon, is enclosed within the spout, and terminating at its lower end at the mouth-piece, so as to be controlled by the lip of the patient. 10 a, a, is the body of the cup ; b, the handle ; c, the bottom ; d, the upper edge or rim of the cup ; e, the web of the siphon ; /, the siphon passage ; g, the air passage; h, the opening communicating with the air passage, by which the siphon is brought into or put out of action. In each of the Figures the same letters represent corresponding parts. 15 Although in the several Figures in the accompanying Sheet of Drawings the cups are shewn as being moulded or formed together with the siphon in one piece, it is evident that the siphon may be attached to a cup, and that cups according to my Invention may be either composed wholly or in part of metal, or wholly or in part of china, earthenware, or other material; and 20 although in the accompanying Drawing I have shewn but three modes of producing and controlling the siphon action, it is evident that the position of the air channel, as also that of the controlling opening, may be changed to suit the particular requirements or the fancy of the person requiring such vessels. 25 In witness whereof, I, the said Robert Henry Emerson, have hereunto set my hand and seal, this Fifteenth day of August 1865.
