SPECIFICATION forming part of Letters Patent'No. 269,143, dated December 12, 1882.

Application filed July 1, 1882. (No model.)

To all whom @t may concern:

Be it known that I, JAMES R. WALLS, of Chicago, Cook county, State of Illinois, have invented certain new and useful Improvements in Steam Cooking-Vessels, of which the following is a specilication. Y

This invention relates to the construction of cooking-vessels for use on steam-tables, and the devices whereby the same are secured to the tables when in use. This class of cookin g-vessels have heretofore been constructed with an outstanding castmetal rim, which rests upon the table and supports the vessel when inserted in the hole in the table. The means used to confine them to the table have been catches located at opposite sides, which pass through notches in the sides of the tableopenings, and which, by rotating the vessel slightly, are made to pass under the table, and so act as retaining-stops. Both ofthese features are much improved by the construction I now adopt, in the following respects: The cast-metal rims are very apt to be untrue, owing to the difficulty inherent in all casting operations, so that they do not form such a close joint with the table as to contine the steam. Ihey are also comparatively more expensive 'and less easily joined to the vessel than the rim The catches also do not conne the vessel closely enough to the table, even if the rim does presenta true edge, to prevent the loss of steam or motion of the vessel.

The nature of the present invention will be understood from the accompanyingdrawings, wherein Figure l is a side elevation, and Fig., 2 a vertical section, of my improved cookingvessel shown in place in a steam-table. Fig. 3 is a bottom view of the same.

In the drawings, A represents a portion of the top of an ordinary steam-table.

Bl represents a cylindrical vessel, of the usual construction, except in respects hereinafter described, and resting in one of the openings in the table. The walls of this vessel are formed -of a single piece of tinned metal, and the upper edge thereof is turned over so as inclose a stiftening wire, b, at the top. A large encircling wire, b', forms the shoulder which supports' the vessel in the table. This wire is applied to the exterior of the vessel, and it is secured by a ring, b21, of tin, soldered to the wall of the vessel below and extending up to Within the embrace ot' thedownturn'ed flange of the wall at the Wire b. By this construction the vesselis provided with a double thickness at the top, so that it is very strong and not easily bent or injured, and the supporting-shoulder is rendered so iirm :and secure thatit Will stand the clamping force to which it is subjected in the use of the fastening devices, which I will now describe. At opposite sides of the exterior of the vessel are the retaining-stops c, which, when the vessel is put into the table, pass through the notches c at the sides of the opening in uthe table.

After being so inserted the vessel isl turned a little inthe opening,\vhich causes the said stops to engage with theinclined surfaces cz, on the under side of the table-top. These surfaces are Vinclined away from the notches c, and the greater the rotation given the vessel the more tightly the stops and the surfaces clamp the same down upon the table. In this manner the cooking-vessels are securely heid against motion of every kind, and cannot be lifted off by the pressure of steam within the table, and at the same time a tight joint between the table and vessel is insured and the escape of the steam prevented. The stops c3 limit the rotation of the vessel. This form ot'supporting-rim is easily made true, and will not break, as do the cast-iron rims form erly used.

I do not claim broadly a vessel with a supporting-shoulder formed of wire and tin, as vessels with analogous rims have been heretofore made; nor do I claim broadly the use of inclined clamping-surfaces for securing cooking-vessels to steam-tables.

The combination of the cooking-vessel having the supporting-rim, constructed as described, and the lockingstops, in combination with the steam-table having the notches and clamping-surfaces, substantially as specified.
