CHARGING-CAR.

Y all whom it may Concern:

Be 1t known that we, FRANK D. CARNEY and Riemann V. MCKAY, citizens of thel United States of America, residing at Steelton, in the county ot' Dauphin and State of Pennsylvania, have invented certain new and useful Improvementsin Charging-Cars; and we do hereby declare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. and to letters or figures of reference marked thereon, which form a part of this specification. v

Our invention relates to mechanism for sintering ore and other fines, and has for its object to provide a cover for any well-known type of sintering pan, whiclifshall not only operate as a covery for the ignition of the material in the pf'n, but shall alsooperate as a .means for charging the pan, and means for leveling thercliargein the pan before sintering. I

Specifically. the cover is mounted on a car truck operated by suitable electrical mechy anism. to which current is supplied through a trolley or otherwise, as will hereinafter be more particularly -pointed out and claimed.

nism for quickly and casily placing rthe rover. on the pan, or for removing it when tiuignition or the sintering operation was completed, and the charging ot the pans. and the leveling of the chargel in thc pans hasl been done manually.

According to our invention we provide a ar carrying the cover, and the cover can be rapidly raised and lowered with respect to the pan when the car has been run over lsaid pan. The cover is also provided Awith a drop-bottom, for carrying alcharge sullicicnt to lill the pan when dumped, said bottom also acting as leveling 'means for leveling the charge in the pan y A`n in its dropped position, and also acting. when raised, as the inclosing cover over the igniting means and pan. The car carries an electric motor` operated from the trolley or its equivalent,

, projecting below, or at least on a level.l with the dumping bottom.

Asa

-The sintering 'pan A is located between track rails 2 andat such a height between these. rails that the cover can be easily applied and removed.

The ear comprises a suitable framework or body 3, of structural iron, provided at one. end with a platform 4 o1ij."wl1i,chI ris mounted the various'mechanisms-required forthe operation of the car. In the frame or body 9,'is'mounted an axle?) and a driven aX'le (3 on the endslof whichare rigidly se-` cured the car wheels 7. The frame 3 is also provided with transv-'erse members 3 adjacent each end of a cover 10, and on'which are mounted antifriction rollers 8 operating in channelsf) on the cover ll0. Acrossthctop of the frame 3 near each end of the cover -10 are shafts 11 and 12', each provided with two levers 13 rigidly secured thereto near the sides-of the cover. Each lever 155 is connect-ed by link '1l to lugs or'ears 15 on the cover. p

The shaft 11 is provided'at one end with a downwardly inclined lever 16. and the shaft 12 i's` provided with an upwardly inclined lever .17. Pivoted on the end of lever 17.'-

Fig. 2, is a rope connect-ion 18, from Vwhich a rod, wire -or rope 19 leads to a like conllO nection 20, pivoted to the end of lever 16, whereby both shafts 11v and 12 are caused to operate sinniltaneousl)Y when the rope ,19 is drawn. This rope 19 is drawn by means of a ropell whose rope connection 22 at one end is also pivoted to lever 17, and whoseA other end is connected to a rope drum 23 on The main driving shaft 24 has allarge spur gear wheel 31 actuated by a pinion 32 of an electric motor 33 supplied with cury rent through a trolley. 34. The lift of the cover 10 need be but a few inches, and it can be raised from the posit1on shown in the drawings -by means of the -.ropes 19 and 21 when the clutch 27 is thrown, after which it may beheld in its raised position by the brake 25, 26, when the clutch is disengaged.

The brake band 26 is connected to a rod 56 which is connected to a crank arm 57 on .a shaft 58 provided with a lever arm .59

operated by a pedal 60, Figs. 2 and 3.

The cover also carries a burner 35 of the type shown in .United States Patent No.

1,064,314, granted June 10, .1913. This burner is connected by a pipe 36, flexible connection 37 and line 38 to oil tank 39on platform 4:. The burner 35 and pipe 36 are 4supported by an angle iron 40 extending across the middle of the cover. j Air is supplied to the burner through a pipe 41 contained within the pipe 36 and 4o having a flexible connection 42 with a line air pipe 43 leading'to a compressed air storage tank 44, also 'on platform l, and which is supplied with compressed air througha pipe 415 fronran air compressor 46 driven by an electric motor 47, also located on platform 4.

The line pipes 3S and 43 are provided with'cut-ofll valves o and a'respectively, located at the platform 1, and actuated by any suitable lever mechanism, indicated at The tops of the airvand oil tanks are connected by a pipe Z) having` a valvec whereby air pressure is applied on the surface of the oil in the tank. 39.

The main driving shaft 2l is. provided with a loose chain wheel 4S arranged to be connected to and disconnected from said .shaft by means of a clutch 49 operated by a 'rod 50, a bell-crank. lever 51, a link and a hand lever 53.

The bottom of the cover 10 consists of a series of louvers or sectional bottoms 61, more clearly shown in Fig. 5, each of which is secured on a shaft 62 and arranged at sulicier. heightvabove the bottom edge of the cover so that when the louvers assume the position shown in dotted lines in Fig. 5 to discharge their loads, the lower edges of these louvers or sectional bottoms will be substantially in a plane with the bottom of.

the cover.` Each shaft 62 is provided with an upwardly inclined lever 63 at one end thereof and between the frame and the cover and'all of these levers 63 are connected to a rod 61,. whereby the louvers'l may be 'simultaneously operated.

Connected to the rod 64 at 65 is a' rope 66 v struction andv operation to brake band 26,

and is connected to a rod 7l, Fig. `3, which is connected to a crank 475 on a rod 76 provided 'with a lever arm 77 that is actuated b v pedal 78, this mechanism being substantially a duplicate of the clutch, drum and brake mechanism on the opposite end of shaft 2l.

7 9 is a controller, `controlling the sup-ply current to the motor 33.

The louver mechanism or drop bottom for the cover 10 is held raised by rod 611, rope 66, drum 67 and brake 68. y

Thecar is run to the mixing plant, or other source of supply of material to be sintered,"a11d the cover is loaded with said material, w zich'is preferably but not necessarily struck off level across the top ofthe cover. The clutch -19 is thrown to clutching position so that the motor will drive the car with the cover suspended in raised position therein. Upon arrivingv in position over the pan A the clutch is disconne'cted and brake 26 is released, thereby permitting the entire cover 10 with its contained load to be lowered onto the pan A. The clutch 63v is then released, and the weight of the load on the louver bottom 61 will cause the louvers to turndown into the dotted line position shown in Fig. 5. The cover is then slightly raised and traversed ba ck and forth, so that the depending louver bottom. 61 will strike the charge level. The extent of this movement need not be greater than the width between the leaves 61. The cover 10 is then lowered againonto the pan and the 'louvers raised into the .position shown in full lines in Fig. 5. Suction is then placed on th`e pan A through its open ends. vThen the valves 0 and a are opened, and compressed air and oil are supplied to the burner 35 and ignited. The ignition of the material to be sintered takes place in about. a minute, 4more or less, after which the supply of fuel and air to the burner is 3130 sinteringthe charge, the air -would iiollow cnt off, the cover'lifted clear of the 'pan, and the ca r 1s drlven again to the mixing plant for another' clia1'ge,wl1ile the combustion of the charge in the pan is maintained and Vthe sintering operation completed by the suction at theen'ds of the pan. v Heretofore 1t has been ldifhcult toA place th chargein the sintering -pan so that it would have a uniform compactness. 'hen the pan.-

was vloaded by shoveling .the material into pan from aphopper. T he. result was that when the pan was placed. under suction for the course of least resistance through the lessj compacted places and bore through at *'"thesefpoints, leaving a large portion of the charge unsintered. The problem of obtainf lng somefpractlcable method of charging these pans that is sutlicientlyeconomical to .beperformed for commei'clal ,purposes has occupied the attention of engineers for some time. IVe believe lthat we have sl'lccessf'ully solved this problem for commercial pur-- poses; instead of obtaining a 'cake from the sintered material. we'obtain acake that con- 'tains' from 60% to 90% of sintered material, and'v this yis due to our method of charging,

This 'method consists in' moistening the charge to about the .consistency of molders sand, subdividing it, and dropping all portions ofthe subdivided charge into the pan -fromthesameheight, so that the same degree of lcompactness will be caused by the one foot, more or less.
