' Specification of Letters Patent. Application filed July 22, 1911. Serial No. 640,006.

Patented Jan. 23,1912.

To all whom it may concern; 9

Be it known that I, RAFFAELO LUCIA, a citizen of-the United -States,residing at Uniontown, in the county of Fayette, State of Pennsylvania, have invented certain new and useful Improvements in Coke-Oven Doors, of which the following is a description, reference being had to the accompanying drawing and to the letters and :figures of reference marked thereon.

The invention relates to new and useful improvements in coke ovens, and more especially to the construction of. the door frame for supporting the door of the coke oven.

An object of the invention is to: providea construction of door frame which shall be sccurelyheld by the walls of the coke oven,

whereby-fa heavy door'having heatresisting material applied thereto, may be properly supported by the door frame.

In the drawings, which show" by way of illustration one embodiment of the invention,Figure 1 is a front view of a coke oven having my improvements applied thereto; Fig. 2 is a sectional view .on the line 2-2 of Fig. 1.

.The coke oven is of the usual construction, and is provided with a, door frame 1,

which consists of side portions and a door sill or base plate 2.; Thedoor-sill 2 at its ends extends into the side walls of theoven, and isembedded therein. a

The sides of the frame areinte ral with the base plate'2 and also extend'into the brick portions of the oven. 'At the upper.

part of the frame are plates 3, which support the brick arch for the oven. Anchor plates L are preferably provided, and these anchor plates are embedded inthe walls of the ovenand overlap same portion of the frame. The ends of the anchor plates f1 are bent downward, as at 5, and are adapted to engage sockets formedin the frame. These anchor plates serve to hold the frame firmly in the walls of the oven, and prevent the dislodging of the frame .on the raking of the oven.

The sides of the frame 1, as clearly shown in Fig. 2, are arranged so as to extend longitudinally of the door sill or base plate 2. These sides are also set back from the rear edge of the base plate, so that the bricks of the wall of the oven may be placed on each side of the door frame. By extending the base plate back of the side frame, said .Mounted within the structure, so that the weight of'the doors when swlngingto open position will not pull the frame from the-oven structure. Furthermore, by this arrangement of the base plate may firmly held in "the brick side frame, the weight of the door causes a straln transversely across the width of the frame, and, therefore, there is no liability of bending the frame.

door section 6 and an upper door section .7 L

These door sections are formed, with long 1 frame 1-- is a lower hinged members 8. The hinged members 8 of the lower. door section 6i are adapted to engage between the supporting lugs 9 and '10, secured to the door frame. The hinged sections 8 on'the upper door' sections 7 are located between the lug 10 and a lug 11 mountedgon the door frame. A'rod'12 is adapted to be insertedi'n the lugs 9, 10 and 11. Preferably the rod is moved'upward' through an opening in the door sill, and by this construction-the rodmaybe readily in? serted or removed, for the purpose one: placing-0r taking out one of thedoor sec tions. As additional means of supporting.

the lower door section, Ihaveprovided a circular track l, on which runs'a roller 15, mounted 1n a sultable bearing carried by the hinged member at the-lower edge of the door section 6, This roller 15 islocated at some distancefrom thepivotal point of the" door, and will, therefore, takeconsiderable welght off the door,'and relieve the'hin'g ed' rod from side strain. p

Theupper door section 7 is supported by a bar 16, which is pivoted onflthe rod 12 and rests againstthe upper part of the lower hinged member of the lower door section. The upper end of the bar 16 is'beveled and rests against an adjusting screw 17, carried by a. lug 18, formed on the upper hinged member of the upper door section. By adjusting the screw 17, the outer end of the door section 7 may be raised or lowered, so i as to swing freely over the top of the lower" door section. The upper door-section 7 is curved on a larger circle than the curvature of the brick arch of the oven, as indicated in -dotted'lines at 19, Fig. 1. This forms a space over the upper -door sectio'n,so as to provide a suitable draft opening for the oven. As a means for, closing said opening wholly or in part, I have provided a segmental plate 20, which is shaped at its upper edge to fit the arch. This plate is mounted .-tions at, the side .walls thereof, are formed with projecting ribs 25, .which are adapted to 'fit grooves formed in the side walls of the end sections of the fire bricks.

As herein shown, I have provided the door with three sections. The adjacent walls of 15 the sections have "corresponding grooves 26.

In assembling the fire bricks, the outer sections are first put place; then the inner section is put in place and the rods 2'? are passed through the upper ledge of the door and through the grooves 26, into the lower ledge of the door. This rod fits the groove between the sections of the fire brick, and efi'ectiVel holds the fire brick secured to the frame 0 the door. I preferably form the fire brick with the outer edges thereof extending to the extreme outer edges of the door, so that there are no metal parts of the door exposed to the intense heat of the coke oven. 1

To aid in carrying the heat away from the 'metal parts of the door, I have formed the inner faces of the fire bricks'with a plurality of channels 28, which as herein shown, are

at: in the doors. This allows a free circulation arranged at right angles to one another, and these channels are in line with openings 29 of the air through these channels which aids :in keepin. the metal parts of the door cool..

" It is o vious that minor chan es in the detailsef construction may be made, without departing from the spirit of my invention, as set forth in the appended claims.

Having thus described my invention, what vI claim as new and desire to secure by Letters Patent, is:

l. A coke oven door including in comb1nation, a door frame having a base plate, side members formed integral therewith, said base plate projecting beyond the side mem bers and being embedded in the wall of the oven the upper ends of said side members having laterally projecting portions 011 which the arch of the oven is adapted to fest, said side members being arranged so as to extend longitudinally of the base plate,

and said base plate extending in rear of'the side members, whereby said side embers may be embedded inthe wall of the ven.

, 2. A coke oven door including in combination, a door frame having a base plate, side members formed integral. therewith, said base plate projectin beyond the side members and being em edded in the wall of the oven, the upper ends of said side members having laterally projecting portions on which the arch of the oven is adapted to rest, said side members being arranged so as to extend longitudinally of the base plate, and said base plate extending in rear of the side members, whereby said side members may be embedded in the wall of the oven, and a door hinged to said door frame and having a line of fire bricks secured thereto.

In testimony whereof I afiix my signature,

in presence of two witnesses.
