SPECIFICATION forming part 0f Letters :Patent No. 535,252, dated March 5, 1895. Application filed September 18,1894. Serial No. 523,422. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH P. Lneenrr, of Carthage, in the county of Jasper, in the State of Missouri, have invented a certain new and useful Improvement in Lids for Tea-Kettles and Like Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improved construction of lids for tea-kettles, coffee-pots, and like vessels, and my invention consists in features of novelty hereinafter fully described and pointed out in the claims.

Figure I is a sectional view of my improved lid, the section being taken on line I-L Fig. II. Fig. II is a top or plan view. Fig. III is a Section showing a slight modification; and Fig. IV is a like view showing still another modication.

Referring to the drawings, 1 represents part of a tea-kettle, coffee-pot or other like vessel, and 2 represents myimproved lid.

The object of my invention is to make a lid through which liquid can be readily poured without removing the lid from the vessel, and which will be self-closing, and which will not open under the steam pressure generated in the vessel.

The lid consists of a downwardly tapering or cone shaped disk 3, having an open end or mouth 4, a bottom flange 3a surrounding the open end or mouth, a vertical upper ange 5 and a horizontal marginal flange 6 that fits over the upper edge of the vessel, the vertical part 5 descending into the mouth of the vessel and the tapering disk 3 providing the contracted opening 4. The opening 4 is closed bya downwardly opening valve 7. This valve is in the form of a disk and is supported at its center so as to open in -any direction, as iudicated by dotted lines in Fig. I. I have in Figs. Iand II shown it centrally supported by a spring arm 8, which connects it with the part 3 of thelid, while in Fig. III I have shown it supported by a coiled spring 9, and in Fig. IV I have shown it supported on a rod 10 pivoted at 11 to the part 3 of the lid, and having an extended end provided with a balance weight 12.

When liquid is poured into the lid or to any part of the surface of the valve 7 thelatter opens and being centrally supported it will tilt and open in either direction, according to the direction in which the stream may fall upon it, thus avoiding, to a great extent, the splashing or rebound of the liquid. When the liquid has passed from the lid into the vessel, the valve will be automatically closed and when steam pressure is generated within the vessel it tends to hold the valve more firmly to its seat rather than to open it.

To further provide against the splashing of the liquid from the lid as itis poured in I employ a perforated or gauze diaphragm 13 extending across the lid at the base of the vertical portion 5 of the lid. This diaphragm is held in place by a ring 14 tightly pressed in place and clamping the up-turned edge 13a of the diaphragm between it and the vertical part 5 of the lid. The ring 14 has a horizontal flange 15 fitting over the horizontal iiange 6 of the lid and the flange 15 termintes in a marginal bead 16 which forms a finish to the exposed edge of the lid.

While the liquid passes freely through the diaphragm 13, yet this diaphragm will act to a great extent to prevent any rebound or splashing of the liquid from the lid when it strikes the inclined sides 3 of the lid and the valve 4.

The lid may be provided with suitable means for lifting it from the vessel, as for instance with a bail 17 as shown in Figs. I and II, or with knobs 18, as shown in Figs. III and IV.

The valve 7 may, if desired, be formed some what crowning as shown by the dotted line 19, Fig. IV, instead of being made fiat as indicated by the full lines.

I have shown the spring 9 in Fig. III connected at its upper end to the diaphragm 13, the valve thus being supported centrally from the diaphragm by means of the spring.

I claim as my invention 1. As a new article of manufacture a lid for vessels comprising a body portion, a downwardly opening valve, closing the mouth of the body portion, means for supporting the valve, and a wire gauze diaphragm located in the body portion over the valve; substantially as described.

2. As a new article of manufacture a lid for vessels comprising a body portion, .a downwardly opening disk-valve, closing the mouth IOO of the body portion, means for supporting the the base of the vertical part 5 of the lid, a ring Valve loosely from its center so as to enable forholding said diaphragmin place, and which it to tilt, in any direction, on its central supis composed of a vertical part, a horizontal i5 port, from one side of the opening to the other part, and a marginal bead, a valve 4 closing 5 side thereof, awire gauze diaphragm located in an opening at the base ofthe cone shaped part the body portion above the disk-valve, and a 3 of the lid, and a spring centrally supportrng for holding the diaphragm in place; subl ing the Valve, substantially as set forth. stantially as described.
