ilLEXANDER HARROUN, OF NEAR SYRACUSE, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 45,057, dated January 20, 1891.
Application filed June 6,1889. Serial No. 313,268. (No model.)
To all whom it may concern:
Be itknown that I, ALEXANDER HARROUN, a citizen of the United States, residing near the city of Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Drinking- Cups, of which the followingis a specification.
It is sometimes advantageous for a number of persons to drink in succession from a cup without purifying the cup or changing the liquid. Some persons have objections to drinking from the common cup in that manner, and among the purposes of my invention is that of providing for cases of this kind. To do this I construct a cup into which the drinker does not breathe while drinking, and the liquid from which that may come in 0011' tact with the drinkers lips or any part of his face does not flow back into the cup to be drank by others, but is drawn off into a sepa rate place prepared for it.
My cup is composed of three principal partsviz, an outside and an inside wall which together form the body of the cup, a closed receptacle or cell below it, and a movable band having an arm attached to it, encircling the cup near the top.
The accompanying drawings are designed to assist in making clear the construction and operation of my cup.
Figure 1 is a vertical section of my cup. Fig. 2 is an outside view partially broken to show internal parts. Fig. 3 is a diminished vertical section of the inside wall, and Fig. 4. is a top view of the movable band.
The two walls of the cup and their relation to each other are illustrated in Fig. 1, the letter 0 referring to the outside and the letter?) referring to the inside wall. These walls are a limited distance apart, less than one-fourth of an inch being usually sufficient, and the interval between them is referred to by the letter 4:. The inside wall is held in place by some suitable means, of which the stem with screw-threads upon it and made fast in anut is a specimen. The stem is referred to by the letter Z) in Fig. 3, and the nut is shown between the middle arrows in Fig. 1, where it is made fast to the outside wall of the cup. At or near the top of the outside wall is a rim passing around the cup and extending outward and inclining upward. Its width will not usually exceed one inch and one fourth, or be less than three-fourths of an inch. The shape of this rim and its angle in relation to the cup are such that when the cup stands upright, as in Fig. 1, a thin fluid upon it will fiow inward, and when the cup is inclined moderately from the perpendicular, as it is in Fig. 2, the fluid will flow outward. This rim is illustrated in Figs. 1 and 2.
The outside wall has an opening in the bottom into a pipe leading to the waste-cell be low. This opening is indicated by the middle arrows in Fig. Land is referred to by the letter 25, and the pipe is referred to by the letter If of the same figure.
The letter h in Figs. 1 and 2 refers to the cell or receptacle for waste fluid,and the pipe 15, through which the fluid passes, delivers it near the bottom of the cell, so that little or none of it will flow back when the cup is inclined greatly to one side.
The letters in Fig.1 refers to an absorbent, like lint or sponge, for holdingthe liquid quiet.
Theletters f and h of Fig.1 refer to places where parts are fasten ed together in case the section below the body of the cup is made in parts.
The inside wall expands at the upper end, so as to extend over the inside edge of the rim of the outside wall a limited distance, usu-v ally from one-eighth to three-eighths of an inch is sulficient. This expansion is shown immediately above the upper arrow in Fig. l, and is also illustrated in the broken part of Fig. 2. A little space is left on all sides between this expansion and the rim below it. This space is shown by the upper arrow to the right in Fig. 1, and it does not usually exceed one-eighth of an inch in width.
The inside wall is covered with a lid, which is a little apart from it to permit the passage of liquids between them. This opening between the wall and lid is referred to by the letter 0 in Figs. 1 and 2. The lid is commonly attached to the wall by a hinge, and a part of the lid is usually made of some transparent material.
A hinge is referred to by the letter (Z in Figs. 1 and 3,and the transparent part of the lid is referred to by the lettere of the same figures.
Vhen the cup is to be used and is inclined from the perpendicular, as is shown in Fig. 2,
the fluid in the cup flows out upon the rim of the outside wall and reaches the lips of the drinker at the place indicated by the arrow in this figure. \Vhen the cup is placed in an upright position again, as shown in Fig. 1, any fluid upon the rim flows down between the walls of the cup into the cell below, as indicated by the arrows in Fig 1.
Fig. 4 illustrates a band passing around the outside wall of the cup just below the rim, having one arm or more attached to it, extending up over the rim and out upon the upper surface of it. The band, with the arms, is intended to be movable either way around the cup, and the band is sometimes made in parts which are connected by joints or fastenings, so that it can be easily put on or taken off at any time. Ajoint and fastening are referred to by the letters 0* and r" in Fig.
4. lhe arms of this band are referred to by the letter g in Figs. 1, 2, and 4. They are designed to serve as pads for Wiping the rim, and they are made in whole or in part of material suitable tor that purpose. The band with which the arm is connected is also referred to by the letter 9 in Figs. 1 and 2.
My claim in this application does not include all cups or vessels for holding fluids having double Walls.
I claim as my invention- 1. A cup the upper part or body of which is formed of two cups 0 and b, one surrounding the other, with the space a; between them, the outside cup having a rim at or near the top extending outward and upward and having the Opening 25 at the bottom, the upper edge of the inside cup being so expanded as to extend over a part of the rim upon the outside cup, and the whole connected with and supported by the base and receptacle h.
2. A cup the upper part or body of whicl is formed of two cups 0 and I), one surrounding the other, with the space 1) between them, the outside cup having a rim at or near the top extending outward and upward and having the opening 25 at the bottom, the upper edge of the inside cup being so expanded as to extend over a part of the rim upon the outside cup, the inside cup having a lid with the space 0 between the lid and the member of the cup to which it belongs, and the whole connected with and supported by the base and receptacle h.
3. A cup the upper part or body of which is formed of two cups 0 and b, one surrounding the other, with the space 7; between them, the outside cup having a rim at or near the top extending outward and upward and having the opening t at the bottom, the upoer edge of the inside cup being so expanded as to extend over a paruot' the rim upon the outside cup, and below the body of the cup the receptacle h, with the pipe t as a medium for conducting fluids into it.
4. A cup the upper partor body of which is formed of two cups 0 and b, with the space 1) between them, one cup surrounding the other, the outside cup having a rim at or near the top extending outward and upward and having the opening 25 at the bottom, the movable band 7', connected wit-h the arm g, the upper edge of the inside cup being so expanded as to extend over a part of the rim upon the outside cup,and the whole connected with and supported by the base and receptacle h, as set forth, and for the purpose described.
