- specification.

This invention has reference to improvements 1n 'apparatus for coke ovens, and is designed more particularly for facilitating the removal of the coked charge from the oven and the deposition thereof into cars or other suitable receptacles.

In'large coke oven plants, the ovens are arranged in a long series., and usually have immediately adjacent to them car tracks for the ready deposition -of the coke, when remove'd from the ovens, into freight ycars for transportation to distant oints.

I have devised means w 'ch form the subject matter of another application for Letters- Patent,whereby the entire contents of a coke oven after the coking operations have been completed is pushed out at one operation from the ovens, so that the coked mass is maintained in as large lumps as ossible for reasons which need not be set fort herein.

The presentl invention relates more particularly to means whereby the conveying of these largemasses of coke from the ovens to cars is greatly facilitated and the invention comprises a conveyer structure mounted upon Ia truck movable upon tracks immediatel adjacent to the series of coke ovens, and this conveyer is constructed to receive the entire charge of` the coke oven at one time and to convey such amount thereof as may not be readil contained upon the conveyer into a gon ola car. constructed to operate with either` a high or low type of cars, and may be moved from oven to oven in order, and `co-acts with a suitable mechanism adapted to pushthe coked charge at one operation from the oven. The structure of the conveyer is such that it may receive the charge directly from the oven and permit a portion thereof to fall into a suitably `placed car, then when moved to the next oven, receive the next charge which underI the action of the pushin mechanism at the front end ofthe Oven Wi 1 push that portion of the coke remaining on the conveyer into the car and the newly ejected charge will replace the one irst pushed out upon the conveyer.

and, also, s

'present invention, but is made The conveyer isl p matter lof another applica-hon, and need not.

In order to faciiitate the passage of the heavy mass .of coke over the conveyer, an endless conveyer structure may be used, and further, in order to prevent the conveying of coke dust and such matters to the cars, a part .of the bottom of the conveyer, either adjacent tothe exit opening of the oven, 'or at any other suitable int in the length of the conveyer, may be fimed with a suitable screen through which ine particles will gravitate into a receptacle from which they may be removed from time to time.

rThe invention will be best understood on reference to the accompanying drawin drawings,.-

Figure 1 is a longitudinal section through a coke oven showing the conveyer in lace at the exit end of the oven, and the pus 'ng apparatus in place at the front end of the oven,

owing la car In position to receive the coke. Fig. 2 is a longitudinal section through the conveyer, showing it in position for depositing coke in a deep gondola car, and Fig. 8 is a similar view showing the con` veyer in position to deposit coke in a shallow gondola car or box car.

Similar numerals of reference are employed to indicate corresponding arts throughout the several igures of the w1 ings. s.

Referring to the drawings, there is shown a coke oven, which may be of referred type, and is of suitable shape and Ilength, but in itself forming no part of the present invention; this coke oven is 'broken in two and only the ends are illustrated. 0n one side of the oven thereisshown a pushing a paratus2, which in itself forms no art o the be specially describe further than to state' that it isprovided with a ushing head 3 and a telescoping carrier t enefor, so arranged as to enter and pass entirelv through Athe coke oven to push or force the charge after the coking operation is finished out subject through the other end opening 4 of the oven.

Within a suitable distance of the exit end of the oven series, it being understood that these coke ovens are arranged in 'a series of many ovens, there is arranged a track 5 parallel with the series of ovens and within suitable proximity thereto. This track is u on an elevation or plateau 6, at the end o which is located another track 7 connected with some railway system and designed for the reception of suitable cars 8, which may be of the` gondola or box type.

The track 5 is adapted to receive a truck 9 upon which is formed a super-structure 10, designed to receive a conve er 11, which latter may have its outer en that is the end remote from the oven, somewhat higher than the oven end. The conveyer structure may be similar to ordinary conveyers, thatl is,'1t comprises a bottom 12 withI spaced side members 13, so that when the lower end of the conveyer is in coincidence with the floor of the oven and o posite the exit opening 4, then the charge ci) coke forced out from the oven under the im ulse of the pushing apparatus-2 is receive upon the conveyer and travels along the same1 until ultimately it drops off of the end of the conveyer into the car 8. 1n order` to adapt the conveyer to, cars of different heights, the discharge end may be formed of a section 14 hinged to the main (portion of the conveyer, as shown at 15, an any suitable means, for holding this hinged end 14 in position and adjusting the same, may be utihzed. In the drawings this is conventionally shown as a latch link 16 hin ed to a bracket 17 fast onI the section 14 an having its free end formed into a tooth 18 arranged to engage against any one of a number of teeth 19 fast on the under side of the bottom of the` conveyer 11. By this means the free end of the conveyer ma be maintainedv in line with the main bo y of the conveyer, or may be tilted downwardly, as shown in Fig. 3, so as to bring the discharge end of the conveyer close to a low gondola or box car, and then Ythe heavy masses of coke will fall but a comparatively short distance before reaching the car. e

There is a liability of there being in the mass of coke material more or less coke dust or dirt, or ashes, and in order to revent this from being carried to the car, t e bottom ofthe conveyer at the end immediately adjacent to the discharge end of the oven, as indicated in the drawings, or some other art-of the conveyer, if so desired, may be ormed with slots, as shown at 20 too small to permit the coke falling through them, but allowing the dust and dirt to readily gravitate from the conveyer.` To prevent the dust and dirt lso extracted from the -mass of coke from accumulating alon the track 5, the :conveyer may be provi ed with a compartment 21de endent from said conveyer coincident wlth the slots or grating 20, and this compartment may be normally closed at each end byr a door 22, so that its contents may be readily removable at' will. It isof advantage to reduce the frictional engagement of the coke with the bottom of conveyer as much as may be, and for this purpose the conveyer may be provided immediatel above its bottom section 12 with an en ess belt 23 of any suitable type, say with endless chain supports at the two edges, assing over rollers 24 and returning beneath the floor 12, the belt being suported at each end upon suitable drums 25.

his belt need extend only through the main body of the conveyer, and will practically eliminate the friction between the coke and I the bottom of theconveyer.

When a charge has been forced out of an oven, the material portion thereof will remain upon the conveyer, and only a comparativel small portion of the first charge will pass om the end 14 into the car 8. The second charge, however, will force the remainder of the first charge from the conveyer, and a certain portion of the second charge -will also, fall into the car. Of course, under these conditions the truck 9 is moved from one coke oven to the next, and the car or cars 8 are appropriately moved until the car is filled, provided each car 8 is too large to be filled by a single oven charge. When the ovens are large enough to contain each a charge sufficient to fill a car, then the cars may remain stationary, while the conveyer is moved from oven to oven.

In an apparatus for coke ovens, a con' v eyer body mounted upon a truck, a fixed grate in the bottom of the conveyer body, a refuse receptacle carried by the conve er body beneath the grating, and a free en ess belt extending lengthwise of the bod between the grating and the end of said ody.
