To all whom t may concern;

Be it known that we, Hormon J. WICKHAM, residing at llflanchester, and Fannnnicrr C. ROCILWELL and WiLBUn L. Snnrann, residing at Hartford, in the county of Hartford and State of Connecticut, citizens of the United States, have invented a new and usef ful Coking-Oven, of which the following is a specification.

This invention relates to an oven which is designed to hold blocks of peat while being baked and transformed into coke.

The object of the invention is to provide an oven which will hold a large quantity ol' peat and which can be sealed very easily, so that gases evolved by the process of coking can flow' out and relieve the interior pressure, but llames or gases of combustion emitted from the furnace cannot enter the oven.

'lhe oven shown in the drawings for the purpose of illustrating the invention. has a chamber for receiving the blocks of peat to be coled and a base which supports the lower end of the chamber and contains line sand or the like granulaiheat-resisting substance, which seals the chamber, as more parH ticularly hereinafter described, and pointed out in the claims.

Figure l of the accompanying drawings shows a side elevation, with part broken away, of a vertical coking-oven which embodies the invention. Fig. 2 shows a horizontal section on the plane indicated by the line 2 2 on Fig. l.

ln the design illustrated the chaniher in which the compressed vblocks of peat are placed is formed of a cast-iron cylinder l, that has a closed dome-shaped top. The` lower end of the cylinder is open, and preferably the edge has notches 2, which will permit the passage of gas from the int'erior when the oven is being used. This cylinder, which ina-y have desired cross-sectional shape and may be any required size, may be made of other material than cast-iron and the top may be formed integral or attached to the cylinder, as convenient.

'lhe hase which is shown for this cylinder is preferably formed of cast-iron, and it has a llat bottom 3, upon which the lower edge of the cylinder rests, an exterior side wall 4,

which encircles the outside of the lower endy of the cylinder, an interior side wall 5, which extends around the inside of the lower end of so that they can be han the cylinder, and 'a tight rentrant bottoni 6. Ribs Taro preferably formed on the under side of the base for guidingy the oven when it is moved into the furnace. The base may be formed of other material than cast-iron, if desired On the interior 4wall of the cylinder are inwardly-projecting lugs 8, and festin on these lugs is a grating 9, preferably Ina e of interwoven wire, although it may be made of other material, if desired. rl'he cylinder lifting it and turning it over.

Peat which has been pressed into blocks of the desired shape and size is packed into the cylinder, and after it has been filled and the grating placed in position the cylinder is trough formed by the side "N hen this is in position, sand or a similar granular heat-resisting substance is packed in the trough about the lower edge of the cylinder, so as to seal the joint. is filled with sand first, the cylinder is Iotated a little, so as to Work its lower edge down into the sand.

ln practice being'filled with peat are approximately two hours. The heat from the fire passes up into the rentrant bottom of the base and around the sides of the cylinder7 and the ngases which are generated in the interior and are forced out through the sand take lire, and the combustion of these gases peat.

lf the trough a number of these ovens afterA placed in a furnace and subjected to the action of a hot re for also aids in heating the oven and coking the sure will percolate through the sand seaand' product-that is; p, .er

may have outwardly-extending lugs 16 for turned over and set with its lower edgein the walls of the base.

In these ovens the gases generated by i l. A coking-oven consisting of a cylill-v drical peat-receiving chamber having 011el end closed and the other end open, anda base receiving the open end of the peatehainber, said base having an exterior Wall that encireles the outside oi the lower end of the' cylinder, an interior wall that extends around the interior of the lower end of the cylinder, and arr-)entrant bottom', substantialiy as specified. l Y I 2. 'A @cking-oven consisting of a cylindrical peat-receiving chamber having one end closed and the other end open, a Screen extending across the chamber near the open end, and a base receiving the open end of the peat-Chamber, said base having an exterior Wall that encircles the outside of the lower end of the'cylinder, and an interior wall that extends around the interior of the lower end of the cylinder, substantially as speified.

earner 3. A coking-oven consisting or a cylindrical peat-receiving q.harnber having one end closed and the ff `ner end openJ a screen extending across thc chamber near the open end, and a base receiving the open end of the peat-chamber, said base having an exterior wall that encircles the outside of the lower end of the cylinder, an interior Wall that extends around the interior ofthe lower end of i the cylinder, and a rentrant bottom, substantially as specified.'
