To all whom it may concern:

. lie-it known that I, DA-YID Games, a citizen of the United States, and ii resident of Chattanooga, in the county of Hamilton and State of Tennessee, have invented a certain now and useful Improvement in Furnace- Qharging Apparatus, of which the followmg is a specification. V

()no ob ect of thls invention is to elevate the level of the charging coke and iron to and there to discharge the door of a furnace same. Another object is to do as much of the work'as possible on the ground level and as possible on the level of the charging floor.

' Another object is to serve more than one furnace by one and the same elevating appw ratllh.

Other objects will appeiu' hereinafter.

- The invention consists of features of construction, arran en'ients and combinations of devices hereinu er described and more arncularly pointed out in the appended claims.

The lnventihn is embodied in the appsratus illustrated in the accompanying drawing, forming part hereof, in which Figure 1 is a front elevation, partly broken away; Fig. 2 is a plan view, partly in secliou on the )lane 2-42 of Fig. 1, and with puptsoluitt Fig. 3 is a sectional view of the upper part of a fm-uace and the char ing apparatus; F ig. 4 is a section on the p one 4-4 of F ig and Fig. 5. 1s a detail view.

In the drawings, the reference symbol A marks a cupola furnace, which may be of any form or type. By preference, two such furnacesare located ad accnt to each other, and the charging apparatus forming the suhjectmatter of this invention is located at a cmivenient distance from th m and is arranged to serve both.

The reference B designates the char ing floor, which is locsted at a suitable love below the charging doors C of the furnaces A. The reference 1 marks a hollow cylinder located equidistantly from the two furnaces A, The front of this c linder is omitted (see rcferenc 2) from t e ground level to near the topef the cylinder. Preferably, the cylinder 1 is built of cast-iron,flan%ed plates bolted or otherwise secured togetier to form the cylihder. The sections 3 are provided internally with hBll!l1g,'0I guide,

faces 4 for couctinn with the periphery of flu table, hereinafter mentioned. and will] inter nal grooves 5, forn'iiugr continuous guides. Just about the ground level, tho cylinder 1 is iormed with a ring (i, the internal diam-- eter of which is at least as great. as a di ,ameter internnllybf the cylinder '1 lhroug'li two grooves 5, all for a purpose to u pour hereinafter. Special plates T form sill and lintel for the door 2 of the cylinder 1.

At the to of the cylinder 1 urc fixcll rhutes 8 9 or delivering charges into the furnaces A or on to the charging liour B. respectively, The chutes 8 set into the charging doors G of the furnaces A. being provided with external flanges at 10 which fit against the outer surfaces of tho furnaces. The chutes 9 are attached in unysuituble manner to the cylinder 1.

Placed centrally of and in axial line with the cylinder 1 is a closed casing 11, which is sunk in the ground and at its top is pro vided with a stuffing box. This casing houses a plunger piston 12 which passes through the said stuffing box and which is adapted to be raised by water-pressure and to be lowered by the release of said pressure. To the upper end of the pliniger 12 is fast a circular table 13 whose periphery adapted 1 showing only the cylinder;

to coact with the bearers 4 as the table rises and falls in the cylinder 1. Under the table 13 is n flange 14- which is provided at suit able distances apart with notches or recesses 15 for a purpose to appear hereinafter.

A Water pipe 16 connects the casing 11 with ahydranlic valve 17 and with a source of supply of water under pressure or head. The valve 17 is operatedhy a lever 18 and a hand rod 19 to admit water to the casing and to discharge it tl erei'rom. The rod 19 has two notches 20 therein, which are adapted to engage with the edge of a hole in the charging floor 13 to lock the valve 17 in each of its two positions for admitting and discharging water to and from the casing 11, and thereby to elevate and lower the table 13. The rod 19 has a suitable hand-piece whereby it may he grasped,

On the table 13 are two pairs of bearings 21 for shafts 22. Two tipping or tilting tracks or rails 23 are hinged upon the shafts or rods 22, and these rails are united rigidly together by means of the cross-bars 24. These rails 23 are so placed or weighted that, normally, they are llorizonifll, a stop or leg 25 thereon resting at such time on the table 13 to retain them in such position. At the outside of one of the rails 23 is a in 26, on which is ivoted an angle lever late 27, said latch being ada ted to chock the wheel of a car N on sai rail.

The table 13 may be turned, by to tating the plunger 12 in the casing. This is done conveniently by means of sockets 28 which are, attached to the table at convenient points, and in which a suitable lever (not shown) may be inserted. In this way, the turntable 13 may be turned to cause the rails to point toward any one of the said chutes 8, 9.

It is preferred to have the tipping of the rails automatic in its action, and, in order to secure this end, transverse stops29 are fixed in bearings at the upper ends of the guides 5 in osition such that they will coact with an arrest the arm30, which, preferably, is rigid with the rails 23 the arrangement being such that, once the arm 30 engages with a stop 29, the continued rise. of the turntable 13 will cause the rails 23 to tip as indicated in full lines in Fig. 3, thus causing the car N to discharge its contents down the corresponding chute. The car N has wheels 0 which run on the rails 23, and it is open at its front and top. The ear is prevented from-running off the rails when these are tipped, by means of a catch 31 rigidly connected with the rails and which engages over a flange 32 on the car N, as shown in Fig. 3, while the pivoted latch 27 is used to chock a rear wheel of the car. The arm 30 is of a length such that it fully enters a guide 5 and also the ring 6, but Without touching by its end; thus, this arm acts to prevent the turntable t'rom turning, once this aim has entered a groove 5, until said arm is again at the level of the ring 6. When the arm 30 is at the level of the ring 6, the turntable 13 may be turned in either direction to bring the arm 30 under the groove 5 which, at the to a of the cylinder, will cause the car to disc arge its load down the desired chute, on the tipping of the rails by i the corresponding stop 29.

Over-tipping of the car may be prevented by any sultab e means, the means for this purpose which are shown in the drawing consisting of stops 35 below the stops 29 and at a greater distance from the axis of the cylinder 1 than are said stops 29; that is, the arm 30 passes the stops 35 as the table ascends, but engages with said stop 35 when the car is tipped as shown in Fig. 3.

The table 13 may haven notch or recess 36 therein underneath the arm 30 to allow that arm to clear the table when thecar is tipped to the full extent pernutted by the sto s 35.

n order to prevent the admissionof water to the casing when the turntable is in its aforesaid, the said lever '01 detent 33 being so arranged and placed that, in any position of the turntable exce t those wherein the arm 30 is alined vertica ly with a groove 5, said detent will strike the ring 14 if it is attempted 'to turn on the water-pressure to elevate the table, but which detent, if the table be in position wherein the arm '30 is alined with a groove 5, will, on operating said lever 18 to turn on the power, enter a notch or recess 15 in the flange 14 and permit the power to be turned on, but its engagement with the flange 14 prevents the turning on of' the power asaforesaid.

Coke or iron is loaded on the car N at any convenient point and the car is then run to the cylinder 1 and into the same upon the said rails 23, the turntable having first been brought to the )roper position by means of a lever and a soc et 28. Thereupon the turntable 13 is turned to briu the arm 30 in vertical alinement with tie proper vertical groove 5, after which, by raising the rod 19,

the table is caused to rise until the arm 30 has engaged with the corresgonding stop 29 and has tipped the rails an car as illustrated, when the rod 19 may be lowered halfway (at which point another notch therein may be provided, halfwaybetween the two shown) to hold the table in its uppermost position until the car is empty, after which the rod l1 is dropped and the car is lowered to the bottom and run out of the cylinder-to be again loaded. The car is made to deliver its load into either furnace or on to the floor adjacent to either furnace by causing the arm 30 to enga 'e with one or another of the grooves 5. Vhen a car is run upon the rails 23, the latch 27 is first moved to its inoperative position, and when the car is on the track, that latch is moved to engage 1t underneath the wheel 0 on its rail and nearest it.
