PUSHER TRACK FOB COKE OVENS' Application filed August 31, 1926. Serial no 132,773.

This invention relates broadly to track supports and in particular to a track structure subjected to abnormal lateral thrust. While not limited thereto the invention arms particularly to provide a track supporting structure for coke oven pushers.

The invention will be apparent from the following specification when read in connection with the accompanying drawings in which--- Fi 1 is a vertical section taken trans verse y of a coke pusher track and showing diagrammatically a portion of an ad acent coke oven and the pusher for discharging the contents of the various ovens in the bat- F 2 is a view of a portion-.of the track foundation viewed from the left of F1g.- 1, the parts being shown inv section. in the 1ntercstof clearness; Fig. 31is anenlarged detail section on line 3-3 of Fig. 2;

Fig. 4 is a similar view on line Fig. 5 is a view illustrating detalls of construction; r

Fig. 6 is a plan of Fig. 3;

Fig. 7 is a detail view of the channel cap or tie plate;

F 8 is a detail view of a wooden tie with the late of Fig. 7 removed; i Fig. 9 is an end view of Fig. 8.

Referring in detail to the drawings, 10 represents conventionally a coke oven of known type having a multiplicit of oven 5 chambers arranged alongside 0 one another. For pushing the coke to the outer chamber, a known type of pusher indicated at numeral 12 is used. This includes a ram 14 with suitable operating mechanism 16, therefor, which is mountedon a pusher car 18 having suitable flanged supporting wheels 20. which ridelongitudinally along the spaced rails 22-22 supported on the longitudinal rigid foundations 24.24'which m the embodiment shown are formed ofconcrete strengthened by suitable reinforcing rods 26. The track rails 2222 are widelyseparated, the distance on centers in some cases being 30 feetgor more. It is, therefore, important to make special provision for maintaining thegauge accurately. To prevent relative displacement of the foundations 24- -24 they are preferably tied toether at intervals by transversely extendmg reinforced concrete beams 25. The

foundation is preferably formed with longitudinall extending bearing portions 27 and 28 whici are offset from one another so as to form a shoulder 30 which is adapted to receive the lateral thrust occasioned by the action of the ram in pushingthe coke from the oven. Removably seated in the foundations 24 are a plurality of ties 32 which are shaped to coact with the bearing portions 27 and 28 and the shoulder 30. Novel means are provided for detachably securing the ties to the foundation so that the same can be easily and quickly removed when necessary or desired. Heretofore, it has been the practice to secure ties and rail fastening clips in place by means of sturdy anchor bolts rigidly imbedded in the foundation. The anchor bolts heretofore used served to anchor each tie to its foundation and of necessity were of such size and strength that they could hold the ties and track in position on the foundation against the enormous lateralthrust of the coke pusher ram.

.My improvement overcomes the objectionable features of the prior arrangements andprovides means whereby the thrust is all taken by a shoulder on the tie which. reacts against the foundation. In my improved arrangement the ties are held in place by means located exterior thereofand when such means are removed the tie can be freely withdrawn by an endwise movement, there being no anchor bolts or other fastening devices securlng 1t tovthe foundation which Wlll interfere with such removal. I

Each tie as shown in detail in Figs. 3 and 8 is formed with offset bearing, portions 34 and 36 and a shoulder 38 for coaction -with the similarly formed bearing portions being burned by hot coke falling on the pusher track, and also provides for an accurate positioning of the various bolts and lag screws and the like which fasten the rail clips and keeper angles to be hereinafter described to the tie and the cap also tends to distribute the railload throughout the length of the coke tie. Secured to thecap on opposite sides of the center line of the rail by suitable rivets 42 are diagonally disposed bars 44 against which are seated rail clips 46 which engage thebase flanges 48 of the rails 22 to hold them in place. Lag,

screws 50 pass through holes in the channel tie cap 40 and are screwed into the wooden body of the tie 32. It is understood that because of the diagonal disposition of the bars 14 a certain lateral adjustment of the osition ofthe rail can be obtained by Slllfling the rail clam 3s longitudinally and clamping them in tie desired position by tightening up the tie screws 50.

a For removably securing the ties 32 to the rigid foundation, I provide keepers which in the embodiment of the invention illustrated comprise angle bars having flanges 52 and 54 which, respectively, overlap the top and ends of the ties. The keepers are preferably made in short sections each section holding for example, five ties in place. Each tie is made fast to the keeper by means of short lag screws 56 passing through suitable holes in the flange 52 of the keeper and the cap l0 as shown in Fig. 3. The keeper bars are firmly yet detachably secured to the foundation by means of anchor bolts 58 having offset portions 60 imbedded in the body of the concrete formdation, The shanks of the anchor bolts are threaded at their upper ends and pass freely through suitable holes in the flanges 52 of the keeper bars and nuts 62 are screwed on the shanks so as to detachably clamp the keepers in position. The anchor bolts 58 are so placed that their offset anchor portions 60 cross certain of the reinforcing rods imbedded in concrete. And the shanks of the anchor bolts, it is noted, are located in spaces between the ties.

With the arrangement described, it is apparent that to remove a tie it is merely necessary to detach the nuts 62 and the lag screws 56 so as to remove the keepers. Then the rail clips 46 on at least one side of the rail are removed (those at the right in Fig. 3) whereupon the tie may he slid out by an endwise movement to the left, the

rail 22 at this time being slightly elevated to permit the har est to pass thereunder. It is noted that with my improved rail supporting structure, ties can be readily removed and replaced without removing the track rail. This is important because in the operation of coke ovens, the work will be seriously interfered with by the removal of rail sections. It is understood, of course, that if necessary the pusher car can occasionally travel over short lengths of track even though some of the ties have been withdrawn. After the pusher leaves the repair zone new ties can be inserted without interfering with the schedule of operations of the oven.

While I have referred to wooden ties, it is understood that the general charactcristics of the invention may be embodied in either molded or cast metal ties and that various other modifications and substitution of equivalents may be made by those skilled in the art without department from the invention as defined in the appended claimsl What I claim is:
