so construct the door Be it known that T, VILLIAM' 0. Aurora,

in the county of Allegheny and State of Pennsylvania, a citizen of the'United States, have invented or discovered;-ccrtain new and useful Improvements "in Doors for Coke-Ovens, &c.. of which inipro\-'ements the following is a specification. 1 i

ll ieitivention described herein relates tocertain improvements in coke oven doors, and hasjor its object a construction whereby the refractory portion .of the door may be held securely in its supporting frame and the latterprotected from the heat.

It is a further object of the invention to that ample draft 0 nmg may be provided at the top of the ooi', such opening being formed by such an arrangement of parts, that it can be readily reduced orentirely closed. a

It is also an object of the invention to connct the door in sections so that one part may be closedto'retain the coal in the oven while the other section is open to permit of the operation of the leveler.

The invention is hereinafter more fully described and claimed. 1 a

In the accompanying drawings forming a. part of this specification Figure 1 is a front elevation of my improved door and its so porting frame detached oven Fig. 2 is an edge elevation of the shown the lines V 5 isa detail v heart-h.

In the preferred construction the door is made in two sections independently hinged to the-supporting post 1, which is firmly secured to the front of the oven by means of hooks 2 embedded in the masonry of the oven and having their ends secured to the post. The post has its lower end ste )ped in the sill or forehearth 3, as shown in i l and 2. The post is provided, where sectional doors are-employed, with a pair of lugs or cars 4 and 5 for each door section, and the frames 6 and f the door sections are provided with pairs of cars or lugs 8 and 9, so spaced with reference to the ears on the post, that the pairs .of ears on the latter will project bet-ween the members of the pairs on the doors or vice versa.

stability the front wall of the coke ovens is made quite thicket the base and its front face give-n considerable batter. Hence in order that thedoor sections may swingtogether and have a (good so bearing on the face of the wall aroun opening thereln, the lugs or ears on the post and door sections are so arranged that the the , pint-les 10 and 11 forming the axes-of rota tion of the door sections will be in a. vertical 15 plane at ri ht anglesto the fron't'wall but will be in iflerent vertical planes at right angles to the first as clearl shown in Flg's. 1 and 2. The framesof t e lower Tsections are arched as shown in Fi being inward and are provided with flan es or retaining walls Hand 15 along two si es and the bottom. The lining 16 is formed of bricks arranged in arch form on the inner surfaces of the frames and between the side flanges 14. The bricks are supported vertically by the flanges 15 along-.the lower edgeof the frames. When the bricks exand under heat, they will become more tightly wedged in place,

keyed in place. When thus secured in lace arm jar or shock, especially such incident to closing the door wi I not have anyloosening effect. As shown in Fig. 4, theili'ning is extended above e .up frames, so as to protect the latter from contj ct with the heat of the oven. The upper portion of the lining of the lower section \"iil protect not only the up er edge of the lower frame but also the i flange 15 of the upper section of the door. As shown in Figs. 3 and 4, the lining extends inward beyond the side flanges 14 and the edges of such lining are designed to contact or nearly contact oven.

In order to revent injury to the lining when closing t e door sections the latter are provided with'ibearing blocks or rojections 17, which face of the oven. The blocks are desirably provided with holes 18 for the insertionmf a hook for o ening the sections. The lower section can e conveniently held closed by a bolt 19 placed in a hole in the sill and 1057 the upper section can be lockedby a pin 20 inserted in a hole in a flange 21 on the lower section. In coking operations rovision must be made for the a Patented Mar. 1.1910.

closing sii'ch opening.

In mg improved door this airinlet is formed y the arch shape of the door itself. The forehearth or sill extends out under the lovveredge of the door, and the edges along the vertical sides of the door contact with the front wall of the oven. These joints along the bottom '10? therewith, and by reason of the bowed ha anger the door a sector shaped opening is ormed atthe top of the door for the inflow of air., This-opening may be partially or completelyclosed by placing brick on of the furnace. V 4

In charging the furnace the lower section of the door is closed so as to prevent coal from dropping out. After (the coal is charged it can be leveled off, by a" suitable tool inserted throngh'the upper portion of the opening. I The upper section" 1s then closed and the joints h ted if necessary.

I claim herein as'my invention:

1. A door for coke ovens, etc having in I combination a snppoitidg .frame', and a lining,formed of agefractoryn aterial and l ',.;having an approximately "uniform thick- 'ness hnd arched to withstand displacement by shocks or jars."

door for coke ovens, etc., having in combination a supporting frame provided on opposite sides with retaining flanges and atlining of refractory material keyed between said flanges, the lining being concave inwardly.

3. A door for coke ovens, etc, having in combination 'a supporting frame, and a limng secured thereto the inner face of the lining being arched and a'pivotal connection "between" the oven and the doorsaid parts being'so arranged that the edgesat the ends of thea'rc'h will bear oil-opposite sides 'of the oven opening. 'top of thedoor' and against the front wall"v ".4. 'A door for coke'ovens having in combination a frame and a plurality of doorasections adapted to be hinged to the frame, the axes of the door sections being indifferent vertical planesand'at an angle to the plane of the door frame; In testimony whereof, I have hereunto set my hand.
