rrtrnnrne DRINKING our.

Application led December 22, 1921. Serial 110.524,06).

To all whom t may concern:

Be it known that I, Form ZoLNEnnvioH, citizen of Russia, residing at 9656 Dyer St., Detroit, in the county of `Wayne and State of Michigan, have invented certain new and useful Improvements in Filtering Drinking Cups, of which the following is a specification.

This invention relates to travelers drinking cups, the invention being intended more particularly for embodiment in travelers drinking cups comprising a series of telej sco ic sections.

- he invention has for an object to provide a drinking cup of this type havinglconveniently embodied therewith a iltering medium whereby the water entering the cup for drinking purposes may be filtered.

For further comprehension of the invention, and of the objects and advantages thereof, references will be had to the following description and accompanying drawings, and tothe appended claims 1n which the various novel features of the invention are more particularly set forth. U

Fig. 1 of the drawings is a perspective view of m improved drinking cup, with the cover t rown back.

Fig. 2 is an axial vertical sectional view of the cup, showingit in collapsed position and with the cover closed.

Fig. 3 is a fra mentary horizontal section, taken on the ine 3-3 of Fig. 2. ln constructing my improved cup l provide a base element 10 formed with an upwardly 'projecting annular flange 10 and telescopicrin 11, the upper ring, indicated specifica ly at 11', having a projecting bead 12 at its upper edge. Fitting on this top ring 11 is a stepped ring 14 having a downwardly projecting outer lange 15 which engages over the bead 12. This ring 14 presents an upper portion 14 fitting snu ly in the said ring 11', and a lower deppen in portion 14 which is, inwardly 0E- set su ciently to engage within the Harige Y on the base element 10 of the cup.` The lower ring portion 14.- has an inturned Bange 16 at its bottom on which the filter member seats. This filter member comprises a charcoal disk 18 having its bottom covered witha double thickness of cheese cloth or the like as at 19, and its top with a single thickness 20. The ilter member may be held in place by frictional engagement with the ring element 14e.

The cup is rovided with a cover 21 which .is shaped to t in the top ring part 14', be-

hinged to the` cover adjacent the opposite side thereof` he ring element 14 is cui'l out at evenly .spaced intervals as at 24 while the registering ilange of the cover 21 is formed with complementary pressed out portions 26 which fit in said cut out openings and frictionally engage the cup ring 11' acting both te hold the cover in place and also the filter ring 14. The frictional en agement between these cover portions 26 an the cu ringll' maybe greater than that between t e anges 12 .and 15 of the rings 11' and 14.

When it is desired to use the cup the flange 15 is-gripped by thetips of the fingers of one hand `and the finger ring 23 is pulled by the other hand to lift the cover. The cup is then expanded and filled with water, after which the lilter rin carrying with it the filter member, and a so the cover 21, is lifted from thecup. When use of the cup is iinished the filter member is replaced, and the 'cover closed.

-Having thus described my invention what I claim as new and desire to protect by Letlters Patent of the United States is as folows:

1. In combination, a cup, a ring fitting in said cup, a filter member carried 'by said ring, and a cover hinged to said ring and adapted to frictionally engage the inner face of the cup., said-ring having cut out ortions through which said cover projects into engagement with the cup.

2. In combination a cup, a stepped ring itting snugly in sai cup and having a top flange engaging over the to of the cup, a lter member carried in sai ring, said ring having a number of cut out portions extending downward from the top thereof, a cover hinged to said top ange and presentin portions `adapted to project through sai cut outportions inthe ring into frictional enga ement with the cup.

3. n, combination, a cup comprising a series of telescopic sections, a stepped ring having an upper-'element tting snugly in the upper one of said sections and an in wardly odset lower element, a filter member seated in said lower element, a cover adapted to it in said upper ring element, said uppei,` ring element having a number of cut out perf sie tions extending the full height thereof, and said cover having corresponding' projections adapted to project radially lnto said cut out portions and frictionally engage the upper cup section.

4. In combinaton, a cup comprising a series of ltelescopic sections, a stepped ring having an upper element Iittin snugly in the uper one of said sections an an inwardly o set lower element, a filter member seated in said lower element, a cover adapted to fit in said upper ring element, said upper ring@` element having a number of cut out ortions extending the full height thereof, said cover having corresponding projections adapted to project radially into said cut out p0rtions and rctionally engage the upper cup section, said ring having a downwardly depending top ange fitting over the said zo upper cup section.

- sai Leesaee ed to it in said upper ring element, said upper ring element having a number of cut out portlons extending the full height J thereof2 said cover having corresponding pro'ections adapted to proJect radiall into cut out portions and frictional y engage the upper cupV section, said ring having a downwardly depending top flange {itting over the said upper cup section, said w cover being hinged to said ring.

In testimony whereof I have afiixed my signature.

FQMA aoLNEREVICH.
