COKE-OVEN DOOR.

' SPECIFICATION forming part of Letters Patent 1\To 725,745, dated'April 21, 1903.

Application filed July 9,1902. Serial No. 114,882. (No model.)

To all whom it may concern: 7

Be it known that LEDWIN A. MOORE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, haveinvented certain new and useful Improvements in Coke-Oven Doors; and I do hereby declare the following 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.

My invention relates, primarily, to cokeovens, has especial reference to doors for closing the ovens, and has for its object means for sealing the doors and dispensing with the use of clay now used for this'purpose; and the invention consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a front elevation showing a door in position on a coke-oven and sealed; Fig. 2, a rear elevation of the door detached; Fig. 3, a vertical longitudinal section on line 3 3, Fig. 2; Fig. 4, a front elevation of a section of the door on an enlarged scale; Fig. 5, a transverse section of the same; Fig. 6, a side view of the brace-bar link-shaft detached; Fig. 7, a like View of the brace-bar hinge-shaft, and Fig. 8 a side and end view of one of the links .or latches detached.

Reference being had to the drawings and the designating characters thereon, l indicates the oven-door, comprising an outer plate or base 2, having a surrounding right-angled member 3, provided with a face 4:, which engages a seat 5, of asbestos or like material, on the door-frame 6. To the base 2 is secured an inwardly-extending section 7, having a surrounding flange 8, by which the section is secured to the base by rivets 9 or bolts.

The door 1 is lined with an insulating material 10-such as asbestos, magnesia, or the like-and over it are laid one or more layers of refractory material, such as tiles or firebrick 11, to serve as a non-cond actor of heat a resistance to the deleterious efiects of the heat of the oven on the doorand to refract or turn the heat of the oven back upon the end of the body of coal in the oven adjacent to the door. This portion of the door being subject to the greatest wear or deterioration due tojthe high degreeof heat in the oven is renewable by replacing the burned-out tiles or brick and the asbestos, and when the sec- ,tion 7 yields to the action of the heat it may be renewed by separating it from the base 2 and replacing it with a new one. The door is provided with a bail12, by which itis raised after it has been withdrawn from the doorframe, and is also provided with an opening 13 for the insertionof a leveling-bar. (Not shown.) The door enters an opening 14 in thedoor-frame 6, which door-frameforms subject-matter of another application for a patent filed herewith and serially numbered 114,884. I

16 16 indicate 'buckstays extending up the front of the coke-oven and are secured to the masonry thereof in any preferred manner, with the bases 17 off-the buckstays resting upon the faces 18 of the-door-frames to hold them in position, and between said buckstays 16 at suitable intervals are secured lugs 19 by bolts 20, passing through the buckstays and the lugs, and-thelugs areprovided with openings 21 21 to receive a shaft 22, which'forms a hin'ge'for the clamping or brace bars 23, mounted on said shaft on bearings 24:, which are eccentric to the shaft, as shown in the cross-section on linec d, Fig.6. The

function of these eccentric bearings is to force the clamping bars against the door of the oven when theshaft 22 ;is revolved by a wrench engaging the square section 25 on the shaft and to press the door against its seat on the door-frame and prevent'play or lost motion between the door and its seat'on the door-frame. The brace-bars-are connected together near their outer ends by a rod 26, with thimbles of gas-pipe 27 on the rod interposed between the bars to properly space them and form a rigid framework for the brace-bars, and each bar isprovided with set-screws 28 28 on opposite sides of the transverse center of the door for the purpose of lining up or truing the door to its seat on the door-frame to produce an absolutely tight or sealed joint to prevent the escape of gas or heat from the oven while the coal is being coked, and thus dispense with the clay now used to seal the joints of coke-oven doors. At the opposite side of the door are lugs 29,

also secured between buckstays 16 by bolts 20, and each lug is provided with an opening 30 to receive a bolt or rod 31, by which the links or latches 32 are secured to the lugs by said bolt passing through an opening 33 in each latch, (see Figs. 5 and 8,) and all the links are connected together by a rod or shaft 34, which is provided with bearings 35, also eccentric to the shaft, as shown in cross-section on line efin Fig. 7, which shaft engages the ends 36 of the brace-bars 23 and presses them toward the door and the door to its seat as the shaft 34: is revolved in the links by a wrench engaging the squared portion 37 of the shaft 34. The set-screws 28 preferably bear upon bosses 38 on the door, and as the inner or exposed portion of the door becomes burned the section '7 is removed and a new one supplied, thus leaving the base 2 for further use.

The brace-bars 23 being secured together by a rod 26, swing laterally on shaft 22 to clear the opening in the door-frame '6 for the insertion and renewal of the door, the insertion of a pusher-head at one end of the oven, and the discharge at the opposite end thereof.

The oven having been discharged of its coke, the door 1 is placed in position in the door-frame, the brace-bars 23 swung into position across the door, the links 32 swung over the ends of the brace-bars, when the shaft 34 is revolved and made to engage with the outer surface of the ends 36 of the bracebars, and the door forced to its seat on the door-frame andfirmly locked thereto.

Having thus fully described my invention, what I claim is l. A coke-oven door consisting of a base, a detachable inner section secured to said base, a non-conducting material serving as a doorlining, and an insulating material between the non-conducting material and said base, both of which materials are within and surrounded by the wall of said section.

2. A coke-oven door consisting of a base provided with an inwardly-projecting member having a face for engagement with a seat on a door-frame, a detachable inner section secured to said base, a door-lining of nonconducting material, and an insulating material, within and surrounded by the Wall of said section.

'3. A coke-oven door; in combination with a plurality of clamping-bars connected at both ends and crossing the door, a shaft extending through the clamping-bars and having bearings eccentric thereto and on which bearings said clamping-barsare mounted, and means for engaging the free ends of all of said bars synchronously.

4. A coke-oven door; in combination with a plurality of hinged clamping-bars connected at both ends and crossing the door, movable links, and a shaft extending through said links and having bearings eccentric thereto and which bearings engage the free ends of the clamping-bars.

5. A coke-oven door; in combination with a plurality of clamping-bars crossing the door, a shaft having bearin gs eccentric thereto and on which the clamping-bars are mounted, movable links, and a shaft extending through the links and havingbearings eccentric thereto which engage said bars.

6. A coke-oven door; in combination with clamping-bars crossing the door, a shaft on which said bars are eccentrically mounted, movable links, and a shaft having bearings thereon eccentric thereto, and which shaft engages the movable links and the free ends of the clamping-bars.

7. A coke-oven door; in combination with a plurality of clamping-bars, movable links, a shaft on which the clamping bars are mounted, and a shaft which passes through the movable links, and means on each of said shafts for forcing the door to its seat by revolving the shafts.

8. A coke-oven door; in combination with clamping-bars, movable links,shafts on which said bars and links are mounted and provided with means for forcing the door to its seat by revolving the shaft, and set-screws in the clamping-bars.

9. A coke-oven door; in combination with a plurality of clamping-bars crossing the door, buckstays on the front of the oven, lugs secured to said buckstays, a shaft engaging said lugs and on which the clamping-bars are mounted, movable links, buckstays on the opposite side of the door, lugs secured to said buckstays and a shaft engaging said lugs and on which said links are mounted,

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