The first demore'careful the construction is, the less and sign realizes the problem'of self-tightening later will occur this warping. This -.is by means of an adjustable elastic packing proved by the fact, that a great number of means, usually an asbestos cord, that is coke oven doors'operated in a thoroughly pressed into the spaceexisting'between door satisfying manner through months and that 55 r and door'frame, this elastic packing means thereupon leakages -occurred suddenly, ow-

This object is obtained according to and obtains the self-tightening effect by the inven-tion by the means, that besides a means of a metal acking, that is by pressmetal packing known per se and arranged to 65 ing iron onto iron, y a metal tightening-face close the channel existing between door and arranged on the door and abutting on a cordoor frame, there is arranged a second packresponding face of the door frame, or by a .ingformed by an elastic and adjustable packmetallic tightening frame, arranged on the ingmeans adapted to be pressed in known door and having a certain spring action, bemanner against the portion which is outside 7 ing pressed onto that portion of the door and surrounds the oven .heads, of the door frame which surroundsthe oven heads. The frame.

35 A drawback, however, of this construction which in'th'e new construction no longer deresides in the-elastic packing means wearing termines the correct position of the door, but V in service in an extraordinarily-short time the elastic packing means serves merely to and this mostly at the two lower door 'cortighten. The main metal packing thus preners, where ,it isclamped first between door vents practically completely the tarry con- 40 and frame, when the door is not exactly instituents of the gases developed in the oven serted. With the second construction, havchambers from exerting any llljllliOllS action ing a metal packing, the wear is naturally upon the elastic packing. This is saved with very small in comparison with the first-menthis. arrangement to an extent hitherto not tioned construction, the'metal packing, how-. obtained, whilst a reliable tightening efiect ever, is very disadvantageous in so far as it is obtained under all circumstances.
particu ar:
In order to allow of the invention to be more easily .linderstood, two preferred embodiments of the invention are illustrated by way of example in the drawings which accompany and form art of this s ecification. In these drawings igs. 1 to 3 i1 ustrate the first, and Fi 4 to 7 the second embodiment. In
Fig. 7 is aportion of Fig. 5 with the door in open position.
The embodiment illustrated in Figs. 1 to 3 will be described first.
The coke oven door which is designed in the usual manner as'stopper door for oventhe oven chamber, providing a gap between the door and door frame; a metallicclosure of the gap is thus obtained. Furthermore, 'a'
frame a made'of an elastic sheet metal plate, is arranged on the door body a, on the outer edge of which frame is provided a labyrinth packing on the side turned toward the oven. This packing substantially consists of a frame piece a in which an elastic ackin means, e. g. an asbestos cord d, is em bedde and .of a smaller tightening frame b mounted on the outer portionof the door frame I) and adapted .to be pressed into the asbestos cord d. Another frame e serves to tighten both the metal packing a b and the elastic packing d b", which frame is fastened likewise on the sheet metal frame a? but on the side remote from the oven. This frame 6 is subdivided so as to form several sections which are stretched in the closing position of the door by bolts f the ends, of which engage wedge faces 9 arranged on the buckstays h. In order to enable the elements of the labyrinth acking to engage each other always' on t e same place when the door is inserted, a guide is provided on top and bottom of the door. This guide substantially consists each of a guide bolt 2' fastened on the door body a by means of an angle-piece k, and of a recess I) provided in the door frame I) and serving to guide bolt 71.
In the embodiment illustrated in Figs. 4 1207 the abutting faces I), which co-operate with the abutting faces a of the door body a and are provided on the door frame 6,. are
arranged on that portion of the latter which surrounds the oven heads. In this way the ends projecting into the oven chambers, of the door frame may be made much. shorter than in the first embodiment. To further tighten the door, an elastic sheet metal frame m is fixed on the door body a, on the outer edge of which frame an elastic packing means, e. g. an asbestos cord, is arranged. Spring-pressed presser bolts a distributed on theddoor edge serveto adjust the packing cor To fix the door in closed position, it is bolted on the buckstays h, as usual. The bolting consists of cross bars t rockingly mounted on and adjustable by means of.
threaded bolts 8, and spiders r, which bars engage recesses it provided on the buckstays It.
As the described tightening device extends all around the door edge, that is, also to the bottom portion of the door, it is impossible to have the coke ramp p extending closely to the oven floor. The gap remainin between oven floorand ramp p has there ore to be bridged by a sheet metal plate q, as illus-.
trated in Fig. 7 after the door has been withdrawn from the door frame, in order to enable a satisfying passage of the coke cake onto the ramp p, when the coke cake is pushed.
What I claim and desire to secure by Letters Patent is 1. In a coke oven having a chamber provided with an opening, a closure for said opening comprising a metal door frame surrounding the opening, a door in said door frame arranged to provide a channel between the door and door frame, said door including a metal frame having shoulders, the inner face of said shoulders facing the oven chamber engaging the outer face of said doorframe at a part thereof inward of said channel so as to provide a metal on metal sealing surface, a portion of said door frame being outward of. said channel and extending transversely to the chamber, at opposite sides of saidopening, and an elastic packing carried by the door and adapted to en-' vided with an opening, a closure for said opening comprising a metal door frame surroundlng the opening, a door in said frame arranged to provide a channel between the door and door frame, one portion of said door frame being inward of said channel and extending inwardly in the direction of the chamber and being provided with shoulders extending transversely of the chambdr, and another portion of said frame being outward of said channel and extending transversely 1,sss,494
' of the chamber at-opposite sides of said opening, said door being provided with a metal frame having shoulders, the inner face I of the shoulders of the door facing the chamher engaging the outer face of the shoulders of the door frame so as to provide a metal on metal sealing surface inward of said channel, and an elastic packing carried by said door and adapted to enga e the outer face of the portion of the door rame that is outward of said channel at opposite sides of said opening. a
In testimony whereof, I have signed my name to this specification.
CARL OTTO.
