COKE-OVEN DOOR.

BPECIFICATION forming part of Letters Patent N0, 294,845, dated March 11, 1884.

I Application filed December 1S, 1853. (No model) To in whom it may concern:

Be it known that we, XVALTER A. BLYTHE and J AMES HENDERSON, citizens of the United States, residing at Dunbar, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Coke-Oven Doors; and we do declare the fol-.

lowing to be 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

Our invention relates to improvements in coke-oven doors; and it consists in the construction, combination, and arrangement of the several parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a front elevation of a coke-oven with the door in place. Fig. 2 is a front view of the oven with the door moved to "one side. Fig. 3 is a plan View of the door. Fig. 4 is a sectional view on line 00 m, Fig. 1 Figs. 5 and 6 show a modifica tion, all of which will be described.

The oven A is provided with the doorway A, which, after the oven is charged, is walled up, as at B, nearly to the top of the doorway, leaving the usual draft-opening, B. The door 0 is adapted to fit in the doorway, with its upper end flush with the upper end of the wall, B. This door, it willbe seen, prevents the air from getting to the wall B, and therefore retains the heat in the oven. However, where the door simply fits in the doorway, it is nec essary to mortar up each side of the door with loam, so as to prevent air from getting be tween the joints. To obviate the use of this loam altogetheig-we provide the door with flanges C, which extend laterally from the opposite sides of the door along the walls of the oven. These flanges, it will be seen, form a tight joint, and keep the air from the wall B, and hence do away with the necessity of the loam at the sides, as will be readily understood. I

In order to regulate the supply of air to the oven through opening B,we provide the slide.- valve D,held in slides on the upper outer face of the door.. XVe prefer to hold this valve as shown high temperature, giving better in Figs. 3 and 6, in which the opposite sides of'the valve slide in slots formed between the upper ends of the flanges and the doors. They are also guided by a strip, D, held at its lower end to the door, and having its upper end extended up over the valve, as shown. A clamping-screw, D", turns through the bar D and bears against the valve, holding the same at any point desired. This valve is adjustable vertically to entirely close or vary the size of the draft-opening B" at will. The valve being held firmlyin guides, there is no danger of its being displaced by the forceof the draft of the oven. It is provided with lugs or handles D",

so that it may be conveniently and easily operated.

By use of the door as above described good results are had, as will be understood from Figs; 5 and 6 and the above description; but in practice we prefer to use the construction which we will now describe, as thereby better results will be had, as will be'presently set forth.

To prevent the heat of the wall from burning the door, we form the latter with a water chamber or jacket, E, which we keep filled with water, so that no scorching or burning of the door will take place. o keep this jacket filled with water in the manner presently described. This chamber extends the full width and height of the door. A fine or air-passage, F, is formed in the door and close to the forward wall of the water-chamber. This flue extends'into the water-chamber, and its back and sidesare subject to the heating action of the water in said chamber. At the lower end this flue opens through the forward .plate of the door, forming the air-inlet F. This inlet is regulated and may be closed by the valve G, which is held similarly to valve D, and may be clamped at any suitable point a desired by means of screw G, turning through strap or-bar G". In operation, the upper valve, D, may be closed, so as to shut out direct draft through opening B. Then, by opening valve i, the air can pass through inlet F, thence through flue F, into the opening B. Inits passage through flue F the air is heated and by time it enters opening B has reached a results, as is well known in the art.

pipe, I, depends from the pipe II, and is proreadily removed from and applied to the oven wit-h an air chamber or passage having an in- A supportingrod, II, is arranged above the doorway, and eitends slightly to each side of same. It is preferably made hollow, and 0011- I nected by pipe II with the water-supply. A

vided with the stop-cock I. An elbow, 1 is swiveled on lower end of pipe I. This elbow may be turned, as shown in Fig. 4-, to deliver water into thejaeket E, or maybe turned out away from over said jacket, as will be readily understood. A hanger, .I, is provided on its upper end with an eye, J, placed and movable laterally on the rod II. The opposite end of this hanger may be secured directly to the door, but is preferably swiveled to upper end of the rod K, which, in connection with horizontal bail K, serves as a handle whereby to move the door.

here the door is made without the waterjacket and vertical tlue or airpassage, we sometimes dispense with bail K and use only rod K and a. vertical bail arranged below said rod K, as will beseen in Fig. 5. Ye prefer, however, to use bail Ii, as shown in Figs. 1, 2, 3, and c.

\Vhen desired to remove the door, it is tilted out, as indicated in dotted lines, Fig. l, and then moved laterally to one side, as shown in Fig. 2. Then it will be seen the weight of the door is taken off the operator, and it may be at will.

Having thus described our invention, what we claim, and desire to secure by Letters Iateat, is-

.l. The door for eolce ovens, provided with lateral flanges, and provided on its upper edge with a verticallyadjustable valve, substantially as set forth.

2. In a eolceoven having its doorway walled nearly to its upper end, the door herein doseribed, fitted to said doorway and having its upper end constructed to tit flush with the up per end of the doorway-wall, and provided let at its outer lower edge and 'an air-exit at its upper side, a valve adjustable over the air- 5 inlet, and slide-valve adj ustable vertically from the upper side of the door, all. arranged and operating substantially as and for the purposes set forth.

The combination of the oven, the horim). zont-al water-pipe arranged above the door way and connected with a water-supply, the door provided with a water-jacket, the c011- nec-ting-pipe depending from the water-pipe and arranged to deliver water into the waterjaelcet, and the hanger-bar journaled at one end on the water-pipe, and having its other end connected with the door, substantially set forth.

4. In a coke-oven having the usual draftopening in the upper end ot' its doorway, the l door having its upper end arranged approximately flush with the upper end of the doorway-wall, and provided with a slide-valveadjustable or movable above said door and in a plane parallel thereto, substantially as and for the purposes set forth.

5. In a coke-oven, the combination, with the door and the supporting-bar secured and arranged above the doorway and extended to one side thereof, of the hanger-bar having one end bent around or otherwise suitably journaled on and movable along the sup )ortingbar, and its other end connected withandsupporting the door, substantially as set forth.

6. 'A coke-oven door provided with a water-jacket and an air flue or passage, said air ilue or passage being projected into said jZlCliOl) and subject on three of its sides to the heating action of the water in said jacket, substantially as and for the purposes set forth.

7. Theherein-described coke-ovendoor,provided with a horizontalv bail or handle, Ii, and the bar 1 having its lower end secured to the door in line with bail Ii, and its other end carried upward and bent outward away from the door, combined with the supporting-bar II, arranged above the door and extended to one side, as described, and the hanger .I, having one end swiveled to the upper end ot bar K, and its other end journaled on and movable along the bar It, all arranged and operating substantially as and for the purposes set forth.

S. The combination, with the door having a water-jacket on its inner side and the waterpipe" arranged above the doorway, and pro' vided with a depending pipe, I, of the pipe I", coupled to and rotatable on pipe I and bent into the approximately 2 shape, substantially as and for the purposes speeiiied.

5). A coke-oven door having a water-jacket on its inner side, and an air ilue or passage arranged in front of and next the wateracket, and provided with means at its upper'and lower sides whereby to regulate the draft, substantially as and for the purposes set forth.
