COKE-OVEN.

sracrrrcArroN forming part of Letters Pereira No. 724,032, dated Marchal, 190e.

Y Application tiled May 16, 1902. Serial No. 107,656. (No model.)

vuseful Improvements in Coke-Ovens; and I do hereby declare the following to he a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use'the same.

My invention relates to certain new and useful improvements in coke-ovens.

In the accompanying drawings, Figure l represents a perspective view of a coke-oven embodying my invention, said view being partly in section and with the oven-door removed. Fig. 2 represents a horizontal crosssection, partly broken away, of a bench of ovens embodying my invention, the middle oven of the series showing the oven-door withdrawn.y Fig. 3 represents a front elevation of the same.

Similar numerals of reference indicate similar parts throughout the several views.

The main characteristic feature of my invention consists in providing a U- shaped Iioor for the oven, while retaining the dome shape of the present beehive oven. I therefore preserve all the advantages of the-beehive oven-such, for instance, as its'good coking qualities-but dispense with the small door in the front part thereof, providing in lieu of said door a door equal in width to the full width of the oven, thereby facilitating the discharging of the coke from the oven.

The perspective view shownin Fig. 1 of the drawings illustrates one-half of the dome 1 of the oven and one-half of the outlying superstructure, this view being chosen to more graphically delineate the relation of the parts to each other. The iioor or bottom 3, as will be readily seen, is U-shaped,widening slightly toward the discharge end. The front part 5 of the superstructure may be sustained (in addition to the support given by the piers 15) by the door-frame 4,whioh extends across the full face or width of the oven-chamber and which may be made of ironor other suitable material. The top 14, rear part 2, and side walls of the superstructure, and the top, rear part, and side walls of the dome derive their support directly from the foundation 6.

The front wall of the dome is supported upon a curved beam 30, supported at its ends upon Vpedestals 32, of brickwork, from which the walls 12 extend forwardly. The beam 30 is joined to the top of the adjacent door-frame beam 31 by a connecting-plate 33 and rivets 34, as shown. l 4

The door consists of the casting 7, having hollow interior spaces 9. Fastened to said casting and projecting outwardly is a plurality of eyebolts 11 for the purpose of readily withdrawing the door from the door casing or frame 4. In the rear side of the door,whicl1, it will'be noted, is curved, is a series of firebricks or tiles 8.

On the upper portion of the casting 7 is hinged the supplementary door 13 on hinges 20, as shown in Fig. 3. Preferably on the lower edge of the door 13 I outa longitudinal slot' or aperture 24 for a purpose hereinafter described. 21 indicates a knob to open the door 13.

The operation vof the oven is substantially as follows: The door 7 being in place within its casing 4, thereby closing the oven, and the'charge having been coked and being ready to sprinkle, the loperator by means of the knob 21 opens the supplementary door 13, so as to be able to insert a sprinkling device for sprinkling the charge. After the coke has been sprinkled the door 7 is withdrawn by means of the eyebolts 11 and is Apushed to one side, thereby exposing the interior of the oven for lits full width. The coke can now be very readily and quickly withdrawn. After the withdrawal of the coke the door is reinserted in the door casing or frame 4, and the new charge of coal to be coked is dropped, as usual, into the oven through its trunnel-hole. The supplementary door 13 being down, the operator can readily level off the charge. The supplementary door 13 is then raised, and the coking of the charge is proceeded with. Ventilation is regulated by the amount of space left open for the pasq sage of air through the Ventilating-slot 24.

It will be understood that before charging. the oven and preliminary to the coking operation I insert in the oven a flexible iron band, of a width somewhat less than the heightA of the door-openingthe band being inserted in such manner that its free ends Vioo are adjacent to the door-opening, while its main body portion lies along the periphery of the lower or charge-containing portion of the oven. This flexible band furnishes means for quickly discharging the coke through the door without obstruction, my invention thus presenting facilities for obtaining beehiveoven coke and at the same time having a capacity for speedy, complete, and clean discharge of the product.

So far as I am aware, it is broadly new to provide a beehive coke-oven with a U -shaped floor and to thus combine the good coking qualities of the beehive oven with the facility of discharging characteristic of the old Welsh oven. I desire, therefore, that my broad claims should have an interpretation commensurate with this generic feature of novelty.

Having th us described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A coke-oven, provided with a vaulted roof of the beehive type and having a U- shaped floor, and a door removable along said lfloor, the inner face of said door conforming in curvature to the inner periphery of the oven; substantially as described.

2. A coke-oven, provided with a vaulted roof of the beehive type and having a U- shaped iioor and a door therefor as wide as the Widest part of the oven-floor;substan tially as described.

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

GEORGE FRANCIS MYERS.
