My invention relates to improvements in coke ovens, and more particu arly to ovens provided with a frame for pressing a packing medium into a ga provided between the ,door and the frame t ereof. The object of the improvements is to provide an oven of this packing medium is pressed into the gap by means of pressing members provided with means for slmultaneous operation from one part of the oven. With this object in view my invention consists in the matters to be described hereinafter and particularly pointed out in the appended claims.

In the accompanying drawings,

Fig. 1, is an elevation showing one of the doors of a coke oven and the means for pilessing the packing medium into `the gap between the door and the frame,

Fig. 2, is an elevation side of the door,

Fig. 3, is a sectional plan view taken on the line 3-3 of Fig. 1,

Fig.O 4, is an elevation similar to the one shown in Fig. 1 and illustrating a modification,

Fig. 5, is an elevation looking from the side of the door, and

Fig. 6, is a sectional plan view taken on the line 6 6 of Fig. 4.

In the example shown in Figs. 1 to 3 the front wall v of the oven is braced by anchors v1 located at opposite sides of the door b. Between the door and the wall of the opening thereof an outwardly flaring gap/w 1s formed which provides a seat for a suitable packing medium h running all around the door The said packing medium is adapted to be pressed into tight contact with the wall of the gap by means of a frame consisting of an angle iron z' and U-shaped transverse members l located suitable distances apart, Fig. 1 show ing five of the said members. The frame z', il is mounted on the door b by means of bracket lc xed to the door and permitting a slight movement of the members 1 towards and away from the wall 'v of the oven. On bolts a fixed to the door b bars a1 are rockingly mounted which are adapted to be rocked into position behind inclined lugs 0 in the looking from the 112,770, and in Germany June 16, 1925. v

form of angle irons fixed to the anchors v1 for holding the door b in position. In bores of the said bars clamping screws g are guided which are adapted for clamping engagement with plates m fixed to the members l so as to impart clamping pressure toy the frame z', 1. As appears from Figs. 1 and 2 the said plates m project from the members "1 respectively upwardly and downwardly at the opposite sides of the doors, and the said projecting portions are inclined towards the wall of the oven, thus providing cam faces for the ends of the screws g when rocking the bars a1 into clamping position. The screws g are adapted to be screwed inwardly more or less for regulating the clamping pressure on the frame z', z'l. In some cases I provide the same at their inner ends with shoes 'n adapted for sliding engagement with the plates m.

' The bars al are connected with each other by a vertical link d, and the said link' is formed with teeth d1 engaged by a pinion d2 secured on a shaft which also carries a handwheel d5. The shaft with pinion and handwheel is mounted in a slide d8 guided on the link d and the slide is connected to one of the bolts a by a swinging link d4. In this way the pinion is .retained in contact with the rack teeth on the link d as the link swings in the oscillating movement of the bars a1.

The operation of the apparatus is as follows: For fixing the door in position the hand wheel d5 is turned in a direction for rocking the bars al into the horizontal positions shown in Fig. l as has been indicated in the said figure by the arrow Thus the said bars engage with their outer ends the lugs c and force the door b inwardly. Further, the bolts g engage the inclined cam plates m thus forcing the packing medium h into the gap fw, the clamping pressure being regulated once for all by screwing the screws g more or less inwardly.

In Figs. 4 to 6 I have shown a modification in which the frame z' for pressing the packing medium into the gap w is acted upon by toggle joints connected to a common operating mechanism. The construction of the oven and the door is the same as has been described with reference toFigs. 1 to 3, and the same letters of reference have been used to indicate corresponding parts. But the door is held in position by means separate from the means for forcing the packing medium into the gap, and any known or preferred means may be used for holding the door in position. v

The frame for forcing the packing medium 71, into the gap w comprises only the angle iron z' bent into rect-angular form. At suitable distances apart brackets 0 are secured to the frame vf and the said brackets are acted upon by toggle joints consisting of links p1 and p2, the links p1 being rockingly mounted on pins p3 mounted in lugs b1 provided on the door b. The links p1 are formed with extensions p4. The said extensions are connected in pairs to transverse rods 1, and all the rods are connected with each other by a link s formed at its middle with a screw-threaded portion t. The said screw-threaded portion is engaged by a hand wheel u the hub of which is held in position between eyes 'al fixed to the door b.

For holding the door in position transverse bars y are rockingly mounted on the door and adapted to be rocked into locking position at the rear of the inclined lugs y1 fixed to the anchors ful, the operation of the said bars y being indicated in Fig. 4 by showing one of the bars respectively in full and broken lines.-

rlhe operation of the apparatus is as follows: The door is iii-st fixedl in position by means of the bars y, in which position the framez' is located in front of the packing medium 71,. Now the hand wheel u is rotated in a direction for pulling the link s downwardly in F ig. l, so that the links p1, p4 are rocked more or less into position perpendicular to the door b. rllhereby the frame z' is forced inwardly and on the packing me- -dium 7i.

`While in describing the invention reference has been made to particular examples embodying the same l wish it to be understood that my invention is not limited to the constructions shown in the drawings, and that various changes may be made in the general arrangement bf the apparatus and the construction of its parts without departing from the invention.

I claim:
