FREDERICK DOERING, OF ST. LOUIS, MISSOURI.

COFFEE-URN.

SPECIFICATION forming part of Letters Patent No. 481,851, dated August 30, 1892. Application led February 16, 1892. Serial No. 421,744. (N o model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK DOERING, of the city of St. Louis, in the State of Missouri,have invented a certain new and useful Improvement in Coffee-Urns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This improvement relates to the manner of supportingan earthenware,stoneware,or glass coffee crock or yessel in the metal case containing the hot Water.

The invention consists in incasing the rim of the coee-vessel with a tin collar having an out-turned marginal ange resting upon the top of the inclosing vessel. The crock is liable to be cracked or broken, and then the Whole urn must be thrown away or the crock removed from the metal case and a new crock substituted.

It is believed that it has heretofore been the constant practice where crooks are used to cement them fastin the metal cases. When this is done, the crock can only be removed with great difficulty and the case is usually destroyed in the operation. "With my improved construction the crock may be simply lifted from the metal case after the dischargepipe has been disconnected.

Figure I is an axialsection of the urn. Fig. II is a horizontal section taken at the jagged line II II, Fig. I. Fig. III is atop view of the urn with the lid and crock-cover removed. Fig. IV is an enlarged detail vertical section taken at line IV IV, Fig. III.

The metal case 1 may be of cylindrical or other form. It is adapted to contain water that may be heated by any usual means.

The supporting-legs are shown at 2.

3 is a funnel fixed to the side of the case, through which water may be poured in. t

Il is the lid of the funnel.

5 is a cock for the discharge of water from the metal case or vessel 1.

6 is the crock or coffee-vessel, having a anged or beaded rim 7, embraced by thelips 8 8b of the metal collar 8.

8a is the upper lip, and 8b is the lower lip. The lip 8f has a fiange 81 fitting over the coffee-vessel, and the lip Sbhas aflange 8e tting under the coffee-vessel. This collar has a flange 8C, that extends over the upper edge 1"L of the vessel 1 and makes a practically tight joint therewith, so as to check the escape of steam. The side of the collar may fit tightly in the top of the vessel 1.

9 is a cover fitting alike the upper parts of the collar 8 aud vessel 1.

10 is the cover of the crock.

11 is a discharge-pipe fitted with a tight joint 12 in the crock, and also with a tight joint 13 in the side of the vessel 1, the pipe extending from the inside of the crock to the outside of the vessel 1 and havingadischargecock 14. The pipe 11 is shown passing through the bottom of the crock. It may pass through any part.

I claim herein as new and of my invention- 1. The combination, with the coffee-vessel and inclosing vessel, of the metal collar 8, secured to the upper rim of the coffee-vessel and fitting the upper rim of the inclosing vessel, substantially as set forth.

2. The combination, with the inclosing vessel and the coffee-vessel having a flange 7, of the collar 8, provided with a ange 8, by which it is supported, with a lower lip 8b, having a flange 8e, and with the upper lip 8, having a iiange 8d, substantially as described.
