Application filed October 31, 1919. Serial No.'334,70t.

T 0 all whom it may concern:-

' Be it known that I, ARTHUR Ronsnrs, a

citizen of the United States residing at.

herein disclosed is intended particularly'for use in connection with lay-product coke ovens and the like, although it will presently appear that the features of invention herein disclosed are notnecessarily limited to use in this particular type of door, but in many cases may he used in connection with doors intended for other uses. However, in order to simplify the illustration and description of the present -invention, and in order to clearly illustrate or exemplify one application of the features of the presentinvention, I have illustrated and described the same as used in connection with a coke oven construction.

hearing the foregoing in mind, it will be understood that these coke oven doors are large and heavy and become very hot during'the operation of the oven. It is, therefore, very desirable to so construct-the door and associate therewith suitable handlinp mechanism so. that the door can be properly seated or removed from time to time during the operation of the oven.

It is customary to provide in connection with a bench of coke ovens, suitable mechanism i'or'pushing the completed coke from the ovens, which mechanism is usually soconstructed that it may be moved into different positions in order to operate on the different ovens. In some cases, I avail myself of the presence of such machine-for the purpose of handling the coke oven doors in seating or removing them. in which case suitable mechanisms are provided in or in conjunction with the pushing'mechanism for extracting and seating the doors. In such cases, I so construct the coke oven door itself that the said mechanism may be readily and securely attached to the particular door which it is desired to manipulate.

In order that the construction and operation of the doors themselves may be more f readily understood. and in order that their relation to such door seating and extractin mechanism may be more readily understoo -I have illustrated and shall describe the door of the present invention in some cases in association or combination with a suitable type of pushing and door extractin mech anisrn, or a portion of such mechanism, but I wish to have it clearly understood that in so doing, I do not limit myself to the use of the door of the present invention in connection with such mechanism.

I will also state at this point that it is very customary toprovidc at the back side of the bench of ovens a coke guide which may be moved from point to point along the bench of ovens to guide the coke into a car or a carriage as it is delivered from any particular oven. The door seating and extracting mechanism which I have illustrated, and will describe as being in-combination with a pushing mechanism may also be used in association and combination with such coke guide or the like, and, therefore, will be understood thiitthe door seating and extracting mechanism may be used in combination with any suitable form of carriage or .the like as desired.

On account of the high temperature existing with the coking or carbonizing chamber it is necessary to provide a special lining for the door. Otherwise the said door must be water cooled. or it will be rapidly burned away. Even where a special lining is provided, it may become desirable to renew the said lining; from time totime. fore, very desirable to so construct the door that the liningmay be readily inserted or removed from the door frame. One of the objects of the present invention is to pro-. vide a construction of door having a perma-. ncnt frame: and a removable lining, which linin; may be readily inserted into or removed from the frame in sections.

Other objects and uses of the invention will appear from the detailed description of thesame whigh consists in the features of construction rind combinations of parts hereinafter described and claimed.

Referring now to the drawings 1 have illustrated the present invention as being applied to a coke oven construction in which there one provided adjacent to the various oven openings the buckstays 15' and 16. While these buckstays constitute in themselves e convenient-means for attachment oi the colts oven doors so as to hold the latter in position, it will be understood that they are in no sense'an essention portion of the door construction.

I will also state that for purpose in con vonience for illustra'tioml have shown in the drawings a typical door such as may be used at the pusher end, said door being provided with a leveller opening: in its upper portion through which a suitable leuelling tool may be manipulated preparatory to the coking operation. 'l'rhis levelling opening is, however. not essential as regards many features of the present invention and in fact necsoce it is unnecessary to use a levelling opening in connection with the doors et the colic end.

A generally rectangular framework or casing" 1'? is provided around each door opening, the same constituting a portion of the fixed structure. This rectangular casin is not essential to the door construction, alt ough it constitutes a convenient portion of the permanent structure, when used. When such casing is wardly in the manner clearly illustrated in Figure 4.

It may be provided with peripheral lug portions 19 against which may he engaged the brackets '20, which are normally attached to the buckstays 15 and 16 and serve .to hold the door frame permanently in position. The door frame is generally ro vided with a shoulder seat 21 against w ich the removable door or a portion thereof may engage.

The door includes a rectangular frame member 22 of contour and siaeproper to close theopening. This door frame member 22 is generally of metal such as cast iron but may he made of other materials if desired. i

The frame member 2% has the bottom cross piece 223, the top cross piece 24, and in (use a lcveller door is provided it may have the intermediate cross piece 25. It will thus be seen that a more or less rectangular structure is provided within which may be located and secured a suitable lin ing for the door. This is the lining designated in its entirety by the numeral 26.

rovided it may have 5, its inner portion 18 anged or tapered in- This lining is generally made up of blocks or bricks of silica or other highly refractory material. and the lining generally projccts inward a substantial distance beyond the edge portion of the iramemember 23 as is clearly. evident from Figures 2, 5, 12 and 13.

Examination of Fig. 14 will reyical the fact that the side portions -29 and 30 of the door frame member 22 are beveled so that the blocks of silica or the like may he wedged into place' It will also be observed from comparison particularly oil-i515. 2 and 14 that the door lining is made up of a num nor of courses each comprising three blocks,

to providesupplemental cross pieces end mes es 36 at various points within the height of 'thedoorso as to distribute the weight of the refractory lining. This construction will also make it possible to distribute the expansion which will occur in the lining so that the minimum amount of movement of the lining blocks will occur between the conditions of maximum and minimum temperature. This fact is illustrated particularly in Fig. 2 wherein will be observedthe expansion'joints 37, 38 and 39 at the upper ends of the respective piles or stacks of lining blocks.

Bly reference to Figs. 1, 12 and 13 in articu ar, there will be observed inserts 40-and 41 at the two sides of the door casing. These inserts are in the nature of expansion joints and when'they are used'the door casing may be made of upper and lower sections designated 17" and 17 respectively, the two sections being kept in alignment in any suitable manner, as by means of dowel pins 42 in the manner clearly evident from examination of Figs. 12 and 13. The insert blocks may be of wood or any other suitable material. v

As previously explained the construction illustrated in the drawings of" this case shows a leveller door 43, since the particular construction illustrated in the drawings'is' that'for use at the pusher side. hen such leveller door is used it may be of any suitable construction, but the particular form illustrated and which I will now describe in detail will be found to possesssimplicity combined with ease and facility of manipulation in the opening and closing movements.

This particular leveller door is of dish shaped formation so that'its edge portion may rest or seat against the door frame. A

' lug 44 is inserted in the front face of the ieveller door and is provided with an internal socket 45. A bifurcated lever 46 has its bifurcations pivoted to the side. portion of the, door frame by a pin 7, and the construction illustrated in Fig. 3 and 4 will i .he found very desirable for this purpose.

haid construction includes the bifurcations 48 and 49 on the end portion of the bar 46.

which bifurcations receive between them lug 50 on the door frame.

The lug 44 is slidably entered within a recess or socket in the back face of the lever 46. hevcrtheless. the arrangement is such that at all positions in nonnal operation of the device the door 43 will be supported-by the lever 46 byincans of said lug 44.

A in 51 is journaled within the lever 46 and said pin has at its inner end a collar 52 which works against the back face of the lever the 46 or works within a recess or socket'in said: lever. Said pin 51 has its inner end thread ed to engage the threads of. the socket 45 so that by rotating the pin 51 in the one direc-' tion or the other the lug 44 and consequently the door elf'l will he moved back and forth with respect to the lever 46. A hand wheel pivot 47. A convenient construction for or unlocking the free end quickly. lockin 7 hat which I ill now explain:

of the lever is-t Referring particularly to Figs. 3 and 5' there will be observed a lug 55 projecting outwardly from the door frame. Said lug has asocket or notch 56 for the accommodation of the free end 54 of the lever 46. A locking member 57 is pivoted to the lug 55 at the point 58. Said locking member 57 has an inwardly facing shoulder 59 which, when the locking device is-thrown down into the osition of Fig. 5, engages the outer face of t e free end 54 to lock the lever inclosed positi0n.- Upon raising the'locking device 57 by means of a hook 6O conveniently pro vided for that purpose, and which may be engaged by a bar or in anyother suitable manner, the lever 46 will be released.

- to lift and permit the free end of the lever to enter the recess 56. At its lower back corner the locking deviceis provided with another lug 62 so that'when' the free end of the lever strikes said lug, it will knock the locking device down again into closed position.-

'I will now explain the construction illustrated for the purpose of locking the door itself in position within the door casing or at the end of'the oven. For this pu ose reference may be had particularly to 6, 7, 8, 12 and 13. At a convenient position on the door,. I provide one or more locking devices, and preferably two, equally spaced in the height of the door. locking devices is conveniently carried on a bracket or the like 63v secured to the door frame or to the cover plate 34 which was previously mentioned.

Within each of the brackets 63 is pivoted or journaled a locking device designated in its'entiret-y by the numeral 64. Each said locking device includes a cross bar 65 the end portions 66 and 67 of which are adapted to lockingly engage suitable stationary elementsi and the locking device also includes one or more arms 68 and 69 the inner ends of which are jonrnaled in'the brackets 63.

In those cases in which buckstays such as igs.

Each of these pose.

. simplicity i 15 and 10'are provided they serve as a convenient support for brackets and Tl wh ch brackets are provided with lugs or the like 72 and 73 against which the end portions 60 and 07 of the locking device may engage. The parts arev preferably so related that when the locking device is dropped or forced down into the closed position of Fig. 8 it will Wedgie against the lugs or stops and thus insure a tight seating of the coke oven door.

I will now explain in detail one form of mechanism which mey be used. for seating or extracting the door, although it will be un derstood that any other suitable form of such mechanisi'u might be used for this pur- The mechanism illustrated comprises a portion of the leveling mechenism. For nillustrution and description, 1 will state that the pushing and leveling mechanism may travel on mils 74: and 75 which extend along parallel to the bench of ovens so that the ent re device may be brought into position adiacent to any particular coke oven. door; Th s mechanism includes also a pair of standards 76 and 77 within which is slidably mounted e beam 78,

the same ordinarily travelling on rollers '79 and 80. A motor 81 serves to move the beam 78 back and forth through the medium of gearing 82 and 83 and a rack 84:. The

1 machine may be caused to travel bn'Cl: and

forth on the rails '74: and 75 by means of n motor 85 in conjunction Withgeering 86, a shaft 87, and gears 88 and 89.

v A head member 90 is connected to the'end portion of the beam 78. This head member is conveniently in the form of a rectangular box like structure and includes the side members 91 and 92. Within the head menu ber 90 is movably mounted a frame having side pieces, 93 end 9 1 (see Figs. 10 and 1.3) and cross pieces 95 and 96 extended between the frame members 93 and 94:. It is-thus evident that there is provided an interior rectangular frame within the outer frame,

the outer frame being secured to the beam 78 and the interior frzfme being vertically movable with respect to the outer frame.

. A shaft 97 is journaled with respect to the side members 91 and 92 of the outer frame in the journals 98 and 99. This shaft 97 carries a bevel pinion 100 which meshes with a hovel gear 101 journaled With respect to the outer frame. This bevel gear 101 in turn carries on lip-right sleeve 102 threaded on its interior and engaging the lower threaded end of a vertical pin 103. The upper end,

of this pin is suitably guided as it moves up and down, and the pin is also shouldered at 104 to engage e cross piece 105 which 811- tends between the members 93 and 9d of the inside frame. The pin 103 is held against rotation in any suitable manner. It "will ndvv be evident that upon rotating the shaft onoc e 0?, which rotation of the shaft may be readily accomplished by means of a hand Wheel 106 the inside frame will be raised orlovv cred with respect to the outside frame.

On the face of the door are provided one or more sockets 10'? and 108 which may be engaged by pins on th'e door seating end ontracting mechanism back and forth as the seatin and extracting mechanism is manipulated. .d or this purpose 1 provide the brackets 109 and 110 which projcct forwardly from the cross pieces 95 and 96 of the insidefrume, which brackets carry the projecting pieces or lugs ll'lend 112 corrcsiondingl'in position to the sockets 107 an 108. t

so as to carry the door vvill now be evident that upon moving the door handling mechanism into 100 the lugs 111 end 112 will engage ,the-

sockets 107 end 108 so as to take the load of the door. Thereafter, the door handling mechanism may be backed away so as to extract the door, and thereafter, the entire ma chine may be caused to travel along the track We to one side or the other.

It wil be evident that before the door can be removed it is necessary to disengage the locking devices. This is done by swinging them upwardly into the position illus- ,;trated for example, in Fig. 13. For this and 108 adjacent to t e locking devices, and in such case it is possible to provide lugs or the like. 113 and 11 1 on brackets 109 and kp-nnpose I convenient! locate the sockets 10? 110 so that the locking devices will be disengaged simultaneously with the engagement of the lugs 111 and 112 with their respective sockets.

While I have herein shown and described onlyn single embodiment of the features of my invention, still it will be understood that I do not limit myself to the said embodiment except as I may do soin the claims.
