I Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed May 16, 1918. Serial 110.234.937.

To. all whom t may concern:

Be it known that 1, THOMAS` P. RUANE, a citizen of the United States, residing at Fairchance, Ain the county of Fayette and State of Pennsylvania, have invented a new and useful Ram-Shovel for Pulling and Cleaning Beehive Coke-Ovens, of which the following isa specification.

This invention has reference to a ram shovel for pulling and cleaning beehive coke ovens, and its object is to provide a device which will not only pull the coke but will clean the oven and thereby save manual labor which has heretofore been employed for the purpose, and will more effectively and more expeditiously perform the operation with a material saving in cost and time.

In accordance with the invention there is provided a. shovel which may in some respects correspond to pulling shovels heretofore used and the shovelis provided with automatic means permitting it to loadeven up to the farther walls of the oven and will withdraw the coke loaded on the shovel and ultimately dump it onto the usual conveyer provided along the front of the oven, beehive ovens being customarily arranged in Arows with conveyers for receiving the withdrawn coke and carrying it to a suitable point for disposition.

The device may be in form similar' to an ordinary shovel in that it is so constructed that it may be shoved by suitable mechanism under the mass of coke in the oven, breaking up the coke, and the body of the shovel is provided with a rockable plate forming the bottom of the shovel and so arranged that, when the shovel is withdrawn from the oven, the plate will overbalance and dump whatever may be on it. Furthermore, the shovel is provided with pivoted wings so arranged that on forcing the shovel into the mass of coke in the oven the mass will ride over the wings and fall back of the shovel, while the wings, on withdrawing the shovel, act as an abutment pulling the coke, which has ridden over the wings, out through the door of the oven. Afew' operations of the shovel effect the cleansing of the oven from coke as thoroughly as the same operation may be performed by hand and more expeditiously, the pulling` and cleaning occuring together. This does away with the necessity of hand labor for cleaning purposes and therefore correspondingly shor'tens and cheapens the operation7 permitting the oven to be recharged in much less time than heretofore.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not coniined to any strict conformity with the showing of the drawings but may be changed and modiiied so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is an elevation of a pulling and cleaning structure in position to start operations on the coked mass in an oven, such oven, and a receiving conveyor associated therewith being shown in vertical section.

Fig. :2 is a` plan `View of the pulling shovel.

Fig. 3 is a rear elevation of the shovel' with the operating bar in cross section.

Fig. 4 is a front elevation ofthe shovel. Fig. 5 is a longitudinal section on the line 5 5 of Fig. 4.

Referring to the drawings, there is shown a small portion of a beehive coke oven 1 `having a door opening 2, a floor 3 and hearth plate 4, these parts all being of customary type. It is usual to arrange hee-hive ovens in rows or batteries with a track along the fronts `for the accommodation of apparatus and such track is indicated at 5 in Fig. 1. Moreover, it is also customary to provide a conveyer along the front of the ovens between the track and the ovens, such conveyer being indicated at 6. For the purpose of pulling the ovens there is provided a truck 7 to run upon the track 5 and this truck carries suitable mechanism including a pulling bar 8. With respect to the parts so far referred to the usual practice may be followed in construction and operation and, hence, no special description or any particular showing of the parts is vdeemed necessary;4

Carried by the bar 8 is a` ram shovel 9 shown in side elevation in Fig. 1, but for the details of construction reference-will be had more particularly to Figs. 2 to 5 inclusive. The shovel comprisesa threesided frame made up of an end bar 10 and side bars 11, the end of the frame remote from the bar l() being open. The free or forward ends of the bars or legs 1l of the frame 9 have outstanding extensions or toe portions. 12 tapering toward their outer extremities both from the front sidewise and from the top downwardly, it being understood that the shovel is moved back and forth along the Hoor of the oven in a substantially horizontal plane. The front edges 13 of the toes 12 are rounded and relatively sharp at their bottom edges and slant upwardly to a rear edge-14 merginginto the tops of the arms 11, which latter increase in height from frontto rear. Where the toes 12 eX- tend laterally beyond the sides 11 they form shoulders 15 contributing to the pulling effeet of the shovel whenwithdrawn from the oven, while the slanting facesof the toes and therelatively sharp front edges thereof facilitate the entrance of these, parts of the shovel under the body of.l coke, indicated at 16 in Fig. 1.

Extending. across the space between the sides or legs 11` immediately to thel rear of the toes 12 isapivot bar or rod 17 traversing the legs 11 and projecting` beyond the outerl edges thereof where the bar maybe held to the shovel' frame by cotter pins-18u or in any other appropriate manner, these pins being well protected from damage by coke because arranged to` the rear of; the toes 12 and below the tops thereof- Mounted on the rod 17 is aplate18ffreely fitting between the legs 11 and extendingfrom the end bar 10 to the front ofthe toes 1,2 at which latter point the plate has a forward curved slanting edge 19. The plate 18 increases in thickness from front to rear and is formed at the front edge 19 with an upstanding rib 20 dropping-back tothe level of the corresponding portion of the plate. Along the line offthe rod 17 the plate has a double slanting rib 21 extending crosswise` thereof and strengthening the plate where traversed by therod as well as constituting a retarder for coke on the plate, preventing such coke from sliding ofl.

The bar- 10 between the legs 11 has a slanting portion 22 and the front edge of the bar.10 below the slanting portion 22vis provided with a.. stop lug 23 which may be of triangular form, while the plate 18` has a top surface rib 24 extending crosswise of the rear edgeof the plate andprovided with a notch 25 to receive the lug 23.

Extending rearwardly from the central portion. of the bar 10 is a socket 26v to receive the bar 8, the bar being made fast in the socket by bolts 27. or inother appropriate manner. Formed on the rear face of the bar 10 are ears 28 flanked by otherfears 29 on a wing member 30 having. aV recessed portionf31` to straddle the. socket member 26. They ears 28 and 29 are hinged together by pins 32 and the wing structure has a range of rocking movement about its pivots 32 from the rear face of the bar 10 to lugs33 rising from the tops of the sides of the socket 26. lVhen the wing structure is in engagement with the bar 10 it stands approximately upright and when in engagement with the lugs 33 it slants rearwardly at a considerable angle, the two positions of the wing structure being shown in dotted and full linesv respectively in Fig. 5.

The plate 18 forming a rockable bottom to the shovel hasa constant tendency to gravitate toward a pendant position raising thefront end'and dropping the rear end, as indicated in dotted lines in Fig. 5.

lVith the structure described, the shovel is forced under-the mass 16 of coke which is lifted andl more orl less broken up by the slanting edge 19- of the plate 18 and the slanting` edges 13 of the-toes 12. The coke rides-onto the plate 18 and is continuously liftedfbecause ofthe slanting top face thereof and: is, furthermore, lifted and broken bythe slantingsurfaces of the toes 12 and the slanting tops of the bars or legs 11 of the main frame of the` shovel. Portions of the broken up coke fall upon the plate 18 and the latterr moves thereunder until the coke ultimately rides over the rib 24, slanting edge 23 and onto the end bar 10 to finally find its way to they wings which at this time bear against the lugs 33 and are` thereby held in a rearwardly slanting position. As the shovel is forced deeper into the mass of coke the disturbed and broken coke falls over-the top of the wings 30 and dropsbehind the advancing shovel. Some of the coke also passes. over the toes 12` and falls behind the shoulders 14C.

When they shovel has been forced deep enough into the coke thedirection of movement is reversed, whereupon, the coke at the. rear of the shovel engages the wings and the latter are brought to an upright position. against thebar 10 so that the coke beingl engaged by an. upright abutment formed by they wings is drawn out of the oven door and ultimately reaches the conveyer 6. The load of coke carried by the dumping plate 1-8 moves with the shovel through the oven door until thepivot pin 17 has approached the edge of the hearth 4 closely enough to permit the mass of coke on the rearv portion of the dumpingbottom plate-18 to overbalance the frontedge thereof, whereupon, the. plate will tip so that its loadl will readily gravitate onto the conveyer. The shovel is again introduced into the oven and withdrawn therefrom and the operationy is repeated as often as needful to extract or pull the coke, while that coke carried by the plate 18 represents, especially toward the end of the pulling operation, those partsof coke charge which heretofore could only be removed by manual operation.

The actuating mechanism for the shovel is of the ordinary type used for known forms of pulling shovels and is capable of moving the shovel to any part of the interior of the oven. The curvature of the front of the shovel may correspond to the interior curvature of the oven so that it may reach practically to the walls of the oven. This permits the shovel to scoop up all or practically all loose particles beyond the reach of the pulling part of the shovel so that the part of the shovel carrying the plate 18 is in effect a cleaning shovel and operates in conjunction with the pulling part of the shovel. rllhis makes it possible to combine the pulling and cleaning operations, thus materially shortening the time needed to discharge the oven ready for a fresh charge.

rlFhetoes 12 with their shoulders 15 form eflicient parts of the shovel in the cleaning ope-ration. When the shovel is pulled out of the oven the toes 12 clean the coke from the jambs and the walls of the oven. The du1nping bottom together with the laterally eX- L tended toes of the body of the shovel thoroughly clean the oven so that itis ready to be recharged and eliminates the necessity of a workman entering the oven to remove material quantities of coke left in the oven by other forms of shovels. l
