PUSHEB-RAM-GHANGING STATION.
Application filed October 20, 1919.
To all whom it may concern:
Be it known that I, WILLIAM LAMAR IL- LIAMS, Jr., a citizen of the United States, residing in Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Pusher-Eam-Changing Stations, of which the following is a specification.
In coking plants, particularly those of the by-product type, the pusher machine moves lengthwise of the battery from one coking chamber to another in regular timed sequence to push. out of the coking chambers or ovens the charges of finished coke. This operation is maintained continuously and consequently it is most essential that proper provision be made for the quick and ready removal of aram from the pusher machine and the substitution of another ram, should this be necessary for one reason or another. The essential object of this invention is the provision of a ram receiving and supporting station constructed to permit a quick and easy transfer of a ram from the pusher machine and also a similarly efficient transfer of a ram from the supporting station to the pusher machine.
A further object of the invention is to construct the ram receiving and supporting station so that it is especially adapted to receive directly from the pusher machine, without any interference whatsoever, a ram of the usual type having a head depending below the bottom of the ram body or shank and a similarly depending shoe supported in the rear of said head. The station is provided with a plurality of ram-supporting devices movable from an inoperative position, that is clear of the path of movement of the head of a ram, into an operative position behind the head of said ram for supporting the latter behind its head, whereby the ram may be moved head first from the pusher machine on to the frame of the supporting station and a ram supported by the supporting station may be moved in the opposite direction on to the carriage of a pusher machine, without any interference between the ram supporting devices and the head and shoe of the ram.
The invention also includes amo'ng'its objects an increasing of the efficiency of operation of an apparatus of this character combined with great simplicity in design and construction and such other improvements or advantages in construction and operation Specification of Letters Patent.

Fig. M is a diagrammatic plan view illustrating the preferred layout of the coke oven battery, the pusher ram machine and the ram receiving and supporting station.
The same characters of reference indicate the same parts throughout the several views.
The pusher machine illustrated in the accompanying drawings is particularly adapted for use in connection with coke-oven batteries of the by-product type. Such batteries are provided with a plurality of crosswise extending parallel heating walls and elongated coking chambers intermediate them, the heating walls being constituted or" a series of vertical flame fines and parallel therewith. Coal is introduced into the several coking chambers or ovens of the battery and when the charges of coal in the chambers have been subjected to coking heat for the required period of time, the finished coke in these chambers is pushed out by means of the ram mounted on the pusher machine.
As shown in Fig. 1, the pusher machine embodies inits construction a suitable carriage, indicated by dotted lines at 21, and adapted to travel on a tracl-iway 22, which extends lengthwise along the pusher side of a coke-oven battery, indicated by dotted lines at 23. The carriage 21 supports reciprocatory ram 24 having the usual head 25 which enters a coking chamber of the oven battery and is made large enough to engage the end face of a charge of nnished coke in said chamber; the ram 2% is also provided with an elongated main body portion or shank 26 constructed of structural metal and having along its bottom edge a rack 2?. The main body or shank 26 oi? the pusher ram must necessarily be of great length, inasmuch as it is required that the ram be thrust substantially clear through the length of the coking chamber in order to empty the latter completely of its charge of finished coke. Tn oruer to support the ram whentraveling through a coking chamber, the head 25 depends beneath the main body or shank 26 of the pusher ram and is provided with a shoe 28 for engaging the bottom 01" the coking chamber; mounted in the rear of the head 25 is another shoe 29 which also slides on the bottom of the coking chamber. The ram reciprocatcs on its carriage between a pair of upstanding guide frames 30, 31 which are respectively provided with upper and lower guiding rollers 32, 33 engaging the top and bottom of the main lJO y of the ram. Mounted at the rear of the carriage 21 is a bearing bracket in which is journaled a rear guide roller 35 adapted to engage the rear portion of the bottom edge of the ram. The usual power-driven gearing is provided on the carriage 21 for pushing a ram through 'a coking chamber and withdrawing the same, said gearing being indicated at 36 and cooperating with the rack 27 to effect forward and back movement of the ram.
In operation, the pusher ram machine is run on the track 22 to a position in front of the coking chamber filled with a charge of finished coke. The ram is then thrust forward through the coking chamber, after the doors of the latter have been removed, and the charge of finished coke is pushed out of the chamber. The ram is then withdrawn and the pusher machine is moved along its track to the next coking chamber horizontal bars 41.
filled with a charge of coke ready to be pushed. The charges of coke are pushed from the several chambers of a coke ovenbattery in regular timed sequence and it is necessary that the pushing operation be effected as soon as the coking of each charge is completed, because of the great tempe ture within the coking chambers which would effect a rapid combustion of the finished coke. Consequently it is highl y important that the pusher ram machine be at all times in condition to perform its v-Jork, and in the event that it becomes necessary to remove the ram from the carriage of the pusher ram machine and substitute another ram the operation of interchan the rams must be effected as quickly an with as great facility as possible. frequently been the practice to employ a number of pusher machines, maintaini 1 one pusher machine, at least, in reserve in the event of a breakdown of the oth r. This, however, involves enormous or; so and may be eliminated by the provision of a means for effecting a quick removal and r placement of the ram oi' the pusher machi e.
The present invention provides a receiving and supporting station that is adapted to hold in readiness a reserve ram and which is constructed to permit a quick and ready removal of the enormously heavy and bulky ram from the pusher machine to the receiving and suppertingstation and a subsequent equally quick and easy transfer or" the reserve ram from the supporting s to the pusher machine, without the tedious and difiicult operation of removing the head or shoe of the ram to permit the shank oil the ram to he transferred to rollers or other supports of fixed height onthe platil orin oi the ram changing station. Tn practice the ram receiving and supporting station is positioned beyond a coke oven battery, preterably at one end of the latter, and en;- bodies in its construction a suitable supporting frame consisting generally of two verti cal frame sections 37, 38 formed of upright beams 39 braced by diagonal bars 40 and These two vertical framesections 37, 38inutually support a horizontal platform 2'formed of structural metal and extending parallel with the direction of movement of a ram on its can riage 21.
Mounted on the plat orm 4%, is a plurality of tracks 4:3, in the present instance tut tracks, each consisting of a pair of tie usual rails 44. These tracks 43 are supported by the frame of the ram receiving and supporting station at the end of the coke ov tery in parallelism therewith and lie with and in the path of movement a ram, the carriage of which is moved to a position in ii t of the frame of the ram receivi and supporting station. The main operatit i a ins; le 'el of each track ot the pair of trncl-zs into a short inoperative "'reclr. level 46 the letter disposed in n plane beneath the plane oi the main portion of the trucks.
