JOHN F. BRADY, 0F PROVIDENCE, RHODE ISLAND.

DRINKING-CUP.

Application filed October 18, 1911, Serial No. 655,358.

To all whom it may concern:

Be it known that I, JOHN F. BRADY, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Drinking-Cups, of which the following is a specification.

My invention relates to metallic drinking cups and its essential objects are facile portability, compactness, freedom from rattling when in collapsed position, non-accessibility to dust, and reversibility of the cover as a base.

To the above ends essentially my invention consists in such novel parts and combinations of parts as fall within the scope of the appended claim.

In the accompanying drawings which form a part of this specification, Figures 1, and 2, are bottom plan and side elevation respectively of my cup in housed position, Figs. 3, and 4, sections of the same on lines :0, c0, and 3 y, respectively of Fig.1, Fig. 5, a side elevation partly broken away of my cup expanded and the housing removed, Fig. 6, a section of the housing on line a, a, of Fig. 1, and Fig. 7, a side elevation of the cup in expanded position and located in the housing, showing the housing partially broken away.

Like reference characters indicate like My cup has a preferably slightly concavo convex base A and its outer edge is rolled over to form a bead, a. Soldered to the up per concave face of this base by solder or otherwise, concentrically therewith and of less diameter than the base is an upwardly tapering sectional collapsible cup B of increasing diameter upwardly. In detail this cup comprises a bottom cup shaped member Z) consisting of a base 7) and an upwardly and outwardly tapering side wall 6 Surrounding the member 6 are a plurality of nested tapering rings 0, of successively greater diameter away from the member B, but whose smaller several diameters are less than the several larger diameters of next adjacent inner rings, so that when the rings are pulled outwardly or expanded the member 11 and the telescoping rings 0 are frictionally connected and form a complete cup as shown in Fig. 5. The uppermost of the rings 0 has preferably a bead c on its upper face.

Specification of Letters Patent.

Patented Dec. 31, T3912. Renewed September 25, 1912. Serial No. 722,369.

Upon the upper face of the base A intermediate the cup B and the bead a is fixed an annular layer or pad, D, preferably of cork, upon which the lower edges of the rings 0 rest when the telescoping member B is collapsed.

A housing or cover F is provided, comprising a preferably concavo convex body, f, and a side f provided near its marginal edge with a resilient downwardly and inwardly annular internal curved flange f which forms a seat for the bead, a, of the base, as shown in Fig. 3.

In order to remove the base from its seat a releasing wedge is provided comprising a plate G loose in an opening g, in margin of the side f of the housing slightly above the plane of the flange F. This plate extends exterior of the housing wall f and is pro vided upon its inner edge with a bevel 9 adapted to contact with the curved under surface of the bead a and expel the base A from its seat when the plate is inwardly pressed. Integral with and soldered to the bottom of the plate G is a spring plate H provided at its opposite end with a bent end portion k soldered to the inner face of the housing body f. The spring arm H whose act-ion end is pressed against the wall f normally presses the plate G outwardly.

It will be observed that substantially all of the operative parts of the described fastening devices are concealed; that it is possible to preserve a substantially unbroken sym-' metrical exterior contour in the entire structure.

The inner face of the body f of the housing F has resting thereagainst or affixed. thereto by any convenient means a sheet or pad J of cork or other non-metallic material adapted, to receive any impact from the bead 0 when the parts are jarred. It will be observed that the members D and J combine to deaden or prevent any rattle or sound from the housed parts when the structure is moved or is carried in the pocket.

An examination of Fig. 7 will indicate that when desired the base A of the cup may be reversed from its position shown in Fig. 3 in which case the housing F serves as a standard or supplemental base for the cup member. The base proper, A, is now held in its seat as before by the catch.

The completed structure is compact, and the exclusion of dust renders the same sanitary.

What I claim is,

A drinking cup embodying a base plate with a marginal bead, a collapsible cup on said base plate, a housing member inclosing the cup and comprising a body portion with a side provided near its marginal edge with a resilient internal curved flange forming a seat for said beach and means for releasing said bead from its seat comprising a spring 10 plate having a portion secured to the inner face of said body and a releasing wedge movable with said spring plate and having a portion projecting through the side wall of the housing.

In testimony whereof I have aflixed my signature in presence of two witnesses.
