Original application filed November 30, 1910, Serial No. 594,942. Divided. and this application filed March 9,

To all whom. it may coin-cern:

Beit known that I, Louis YiLrtrrn, a subject ot' the Kingdom ot Great lritain. residing in Joliet, in the countv ot lill and 'State ot Illinois. have invented a new andy double doors for coke-ovens, and the invention consists in `the novel parts, and conibinations ot parts and devices, hereinafter particularly described, set forth, shown, and claimed.

In the accompanying drawings which form a part of this specification, Figure 1 is a front View of a coke-oven showing a face view of the outer door, applied and sealed; Fig. 2 is a sectional view on the line 5).-2 of Fig. 1, a portion being added to the' section. above `the limits of said F 1: Fig. 3 1s a cross section on the line 3-3 ot i Fig. 1, the section being, however, upon a larger scale than said Fig. l: Fig.A 4 1sa tace view of the outer door with the cotter bars removed therefrom; Fig. 5 is a fragmentary view of the face of the inner door showing its two pivoted latches.

Tn said drawing ll is the interior ot the oven; 12 the flooring thereof, 13 the. inout-h or door opening of said oven, made with an open-ing somewhat Haring to more readil7 receive and center the plug door. This plug-door, or inner door, consists of the rectangular frame, 14, having' the inwardlv projecting flange, 15, extending entirelyY around the door, td receive and retain the tire-brick lining 1G, and having the laterally projecting flange 17 to set against the face 1S of the door masonry jamb at the top and sides ot the door. At, the bottom ot the plug-door its metal trame is made with an opening through to receive the single plug brick 19. rl`his openingis'intended for the introduction of an oil or gas burnerin the preliminariv heating ot the oven, the burner being thrust. through and Aburned unt-il the oven is preliminarily warmed, after which the burner is withdrawn and the plug brick inserted closing the opening previous to the filling of the oven with coal for coking. 20, 20 show the usual buck-stays of the oven.

,above the side hooks.'

Serial No. 613,358.

91, 2l are two brackets one at each side et and below, the door opening. These brackets are secured to the buck-stays; Surrounding` the door opening is a metal jamb 22, secured to the brackets Q1. The inner lateral tace ot this jamb grooved as at 23. Vlpon the tace ot the plug door are secured lifting sockets Q4, 24, to receive the lifting hooks of, preferably, a suitable twin crane to be used for opening and closing the doors b v a lifting and witlulrawing act ion, Pivoted to the tace of 'the plug door at each ot the said sockets Q-l are the latches to engage the groove 253 in the jamb to hold thel plug door in place. The lower edge of these latches 2li extend -iar enough below the downwardly opening mouth of the sockets 24 so that when the liftingl hooks engage said sockets the. latches, by this act, will he lifted, or turned -upon `their pivots, and un.- latched 'from the groove Q3. One ot the lat-ches engages the jaml'i at one side, and the other at the other side. of the door, as will be understood 'trom Fig. 5.

re now go to a description of the outer door. This outer door, QG, is a metallic one, made with an inwardly projecting sharp 'flange Q7, all around atthe sides and top and bottom, adapted to encounter an asbestos or other packingl cushion 2S placed preferably in a groove, 29, in the outer face ot the door janib 0n the outer face of this-door are the lifting sockets, 30, similar to the sockets upon the outer tace of the plug door, and for the same purpose, namel)vv to receive the lifting hooks for the removal of the door. Cotter-bins, 2,1, are looeelj)7 attached to the door b v pins 32, so as to have a movement to some extent toward and away from the door. The ends of these Cotter bars extend at eaeh side beyond the sides of the door` 'and .tar enough to engage the upwardly pointing hooks, 33, secured to each side of the door janib 22. At the center ot each Cotter-bar is a screw, 34, which mayV have a square head, to receive a removable operating crank, 36. This screw is tapped into the cotter bar and opposite to it in the face of the door is the shallow cavity 37 to receive the point of the screw.

W'hen the outerdoor is to be set in place, it is rst placed, by the lifting hooks, into approximate position, the Cotter barsbeing The door is vthen lowered until the projections, 40, at the i erally, from one side orthe other, until .it

is exactly centered. The door, as will be seen, is thus centered at the top and bottom and sides .so that its inwardly projecting sharp flange is brought against the asbestos packing always in exactly the same place. This insures a perfect seal, no matter whether the metallic parts-may have warped or not; because the impression having been made in the packing remains the saine and the door is always'brought to and so fits it. When the door is in proper position the screws are turned forcing the ends of the Cotter-bars out against the retaining hooks and the edges of the flange of the door against the joint. i I claim l. The coke-oven closure comprising in combination an unattached inner plug .door and an unattached outer door, means for sealing said outer door l.and both applicable packing thus forminga perfect and removable by a bodily lateral movement and entirely detachable from the oven, substantially as specified.

2. The coke-oven closure comprisingin combination, an unattached inner plug door and an unattached -outer sealing door, both 'applicable and removable by a bodily lateral movement and entirely detachable` from the oven, the inner' plug'door being furnished with lire-brick insulation and the outer door being provided with a continuous sealing flange adapted to set against-a packngi on the door` j amb, substantially as speci- 3. The coke-oven closure comprisingV in combination, an unattaclied inner plug door and an unattached outer sealing door, both applicable and removable by a bodily flat- -eral movement and entirely detachable from the oven, the inner plug door being furnished with fire-brick insulation and the -outer door being provided with a continuous sealing flange adapted to set against a packing on the door jamb, the inner'plug door being furnished with fire brick insulation and with latches taking into the door jambs and the outer door being provided with a continifous sealing flange adapted to set against apacking on the door jamb, and having the set screws and the cotter bars en- Oaging hooks on the j ambs for compressing Jthev door to the` packing, substantially as specified.

4. The coke-oven closure comprising in combination, an unattachedinner plug door and an unattached sealing door both applicable and removable b-y a bodily lateral movement and entirely detachable from the oven, each of said doors being provided with sockets to receive lifting hooks for applying and removing them, substantially as specified. l

5. The unattached coke-oven plug door furnished on its outer face with the .lifting hook sockets and applicahleandgienloyable by a straight horizontallmovement, and provided with the lateral latches, substantially as specified. 1

6. The unattached coke-oven plug door furnished on its outer face with the lifting hook sockets and applicable and removable by a. straight horizontal movement, and provided with the flateral latches, placed adjacent to the hook sockets and in the path of the hook that engages the saidq socket, substantially as specified.

7. The outer sealing door adapted to be lifted into place and having the centering device consisting of the wedge projectionsat the sides, whereby the door is laterally adjusted to an exactr position as it is being lowered to place, substantially as specified.

.8. The outer sealing door adapted to be lifted into place and having the centering device consisting of the wedge projegtmns r-, .m

at the sides, whereby the door Viel'afterally adjusted to an eXact position as it is being lowered to place, and the centering projections at the bottom 'so that the door when placed always occupies the same position and the sealing flange compresses the packing at the same identical groove or place whenever the door is applied, substantially as specified.
