Specification of Letters Patent.

Patented May 28, 1918.

Application filed November 5, 1917. Serial No. 200,404.

This invention relates to certain new and v useful improvements in straining or filtering 'devi'cesto be" used in connection with drinking vessels or the like.

The principal object of the invention is to provide a strainer which will fit within the upper end of a drinking cup .or the like and which will serve to strain or filter water or other liquid as the same is being poured into the vessel and also as it is being poured out of the vessel.

Another object of the invention is to provide a device of this character which will be extremely simple, strong, durable and inexpensive in construction, efiicient and reliable in operation and well adapted to the purpose for which it is designed.

With this and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings wherein the preferred form of the invention is shown:

Figure 1 is a perspective view of a well known form of drinking cup, showing a device constructed in accordance with this invention applied thereto;

Fig. 2 is vertical sectional view through the cup, the latter being disposed in a tilted position to show the manner in which the contents of the cup is dispersed from the same during the drinking operation;

Fig. 3 is a front view of the device removed from the cup; and

Fig. 4 is a perspective view of an ordinary table glass showing the device attached to the same.

Referring more particularly to the drawings, the numeral 1 designates an annular rim which fits upon the upper edge of a suitable drinking vessel, which may take the form of a cup a as shown in Figs. 1 and 2 or a table glass 6, shown in Fig. 4:. The rim 1 is provided with a comparatively narrow annular depending flange 2 at its outer edge, said flange being adapted to hook around the upper edge of the drinking vessel. The inner edge of the rim 1 is provided with a comparatively wide depending flange 3. The rim is preferably inclined from its outer to its inner edge, and is provided with a mouth opening l on one side thereof. Arranged in the flange 3 adjacent to the opening an opening 5. Fitted over the open lower end of the flange 3 is a capshaped member 6 made of suitable straining material, preferably wire screening of very fine mesh. Strips '7 and 8 of the same material are disposed over the openings 4 and 5 respectively, as shown by the drawings. The rim 1 is comparatively narrow and in order to prevent the contents of the vessel from spilling over the inner edge of the rim when the vessel is being tilted to one side, the rim is widened at a point adjacent the opening 4 to form in effect a guard plate 9.

When the device is attached to a drinking vessel as shown in the drawings, as water or other liquid is poured into the vessel through the central portion of the device. any sediment or impurities will. be collected in the screen cap 6 as the water passes through the same into the bottom of the vessel. When a person desires to drink the contents of the vessel, the latter is tilted toward the opening t, so that said contents will pass out of the vessel through said opening, and any sediment or impurities which pass through the screen cap 6 will be prevented from passing into the mouth of the person who is drinking by screen strip 8. If the vessel is rather full of water or other liquid a portion of the latter will not pass through the screen cap 6 into the bottom of the vessel but will pass through the screen strip 7 disposed over the opening 5. in flange 3 and thence through the screen strip 8 over the opening 4: in the rim 1.

It is to be understood that the device may be made in various sizes and shapes to fit various forms of drinking vessels, and that it can be made of various materials suitable for the purpose. Numerous other changes in form, proportion, and in the minor details of construction may be resorted to without departing from the splrit of this invention,

and hence I do not wish to be limited to the construction herein shown and described other than as claimed.

I claim:

1. A straining attachment for drinking vessels comprising a rim adapted to fit upon the upper edge of a vessel and having a mouth opening therein, an annular flange depending from the central portion of said terial fitted upon the lower end of said flange, and a strip of straining material stretched over the mouth opening of said rim.

3. A straining attachment for drinking Gcpies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, 7

vessels comprising an annular rim havin a narrow flange depending from the outer edge thereof and adapted to hook around the upper edge of a vessel," said rim' inclining downwardly from its outer edge to its inner edge and having a mouth openin therein, a comparatively wide annular ange depending from the inner edge of said rim and having an opening therein disposed adjacent to said mouth opening, a cap-shaped member of wire screen fitted upon the lower end ofsaid flange, strips of wire screen stretched over the mouth opening of said rim and the opening in the side of said flange, and a guard plate connected to said rim and disposed adjacent the mouth opening therein.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
