TEACKELEVATIN'G MEoHANIsiu.

To all whom t may concern/.f

Be it known that I, FRANK ErTnoUrin-iN, a citizen of the United States, and resident of But1er,in the county of Butler and State of Pennsylvania, have invented anew and useful Improvementv in Track-Elevating Mechanism; and l do hereby ,declare the following to be a full, clear, andexact description thereof. l

My invention relates to track elevating mechanism and more particularly'to 'track elevating mechanism adapted for use ink connection with apparatus' for .charging glass furnace potssuch as described and ,claimed in an application filed "by meiv on March 5, 1919,* Serial No. 280,839, Letters ,Patent or the United States No.,1,336,494.

That apparatus consists, generally stated in a suitable frame with a batch supply receptacle carried thereby, a verticalundu.- lating track cn said iframe, a carriage on said track, and a tiltable ladle mountedon said carriage .vhereo'. ,said ladle.maiy ce broughtV into position to receivethebatch from said receptacle v'advanced into the fur-- lnace, andflifted to avoid lstrikingthe edges Y or' the pot and thentiltedftodischargethe batch into said pot; f the -above apparatus; is used in. connection'with a'furnace.diere there are a number-.of diferentcharging openings, .and in practice theseopenings are` not oi the. same height but may vary slightly, rthe vtrack may'not be adapted for directing the ladle properlyl into all the openings, and it is the object of my .present invention to provide meansI lor elevating the track so that a ladle will enter each opening without interference.

1n the. accompanying drawing, Fig. 1 is a side elevation of my invention`-shown in connection with the above apparatus, the furnace being'shown in section. Fig. 2 is an enlarged detail of theadjustable track section; and Fig. 3 is a cross section oia same.

lnV the drawing, the numeral 2 designates an electrically driven trolley arranged to run on the underhung tracks l3 between the girders 4 of a suitable electric crane which spans the furnace room and arrangedk to travel on the tracks. This trolley is also adapted Ato run over the tracks 3 to the tracks 6 leading to the batch mixer or the storage bin (not shown) for chargingthe hopperS carried by the trolley 2,

The frame-work 9 is made of structural y Spcificat'oiiof iettersilartent. l'fillted 4, 1922. Application filed my 22, Y

Y steel vproperlybraced and v trussed vto give requisite strength.v

@Supported inthe frame-work 9 are'the tracks 10 and 11V parallel with eacliwother and arranged one above the other. `The track v11 is provided with inclined portions and 13 and they track 1() with the inclined portions l14- and'15 therebyproducing an undulating effect. Furthermore, the upper track 1 0 extends beyond'the track 11 for the purpose more fully' hereinafter set forth.r

. In the track 10 intermediate'the portions 14and 15 is the adjustable or elevatingsection 16 composed of two parallel rails 17 and 18 fitting downy between the stationaryA Arms 21 A.arev

track members 19 and 20.- pivotally mounted` between the stationary track members 19 and 20 on the bolts 22l passing through said members, thefupper ends of said arms bearing .against thefad-` justable rails 17 and 18. The lower endsof the arms 211 are pivotally connected by the bolts 23 to the 4.bar-S24. 1A lever-frame 2.5

is pivotally mountedon the bolts26fpassing throughV the stationary track-members* 19 ber28 of the lever-frameis.l of such height as to permit ofthe passage through said .80, and 20, the lower ends of saidleverbeng l pivotally vconnected bythe bolt 27thlever-frame of the carriage 29 which wis adapted to travel onthe tracks 10 and'11, the vfront wheels 30 of said carriage traveling on the upper track 10,-andv the rear i wheelsr31` traveling'on the lower track 11.

VThe rails-of vthe track'l'l are provided with rack-bars 32 andthe pinions 33 mounted Aon the 'rear Wheels. of saidy carriage engage.v

said rack-bars-f-A suitable electric motor 34 is provided on thev carriage for advancing and 4withdrawing the same, said motor being connectedup with the rear'aXle-to drive the pinions 33. l

Mounted on the carriage 29 is the housing 35said housing being s wiveled so as to be tree to turn. y

Within the housing 34 is a the ladle-shaft 36. A ladle 37 is carried at the forward end of the shaft 36 and at the rear end of said shaft is the bevel-pinion 38 which engages the rack-segment 39 supported by the carriage 29.

Idle-rollers 40 are carried by the housing 35 and said rollers engage opposite sides of the guide-rail 41 on the frame 9. ,"At the ,"lfIn'apparatus forcharging 4glass fur-4 forward end of theguide rail al is a suitable switch forv directing the housing `to the` right or left according to which potis to be illed, but it has not been deemed necessary to illustrate `this in det-ail, as it lformsnoipart.

of the present invention.

VThe furnace 4.2is of the ordinary typev with the pots 43 arranged therein and with openings 44, one jacent pots.

When itis ydesired to charge ,-one'fof the opening for each- `two adpots, thetrolley l2 is run onto the track 3 and bythe electric crane the trolley is moved into position to charge the pots, Vas indicated in Fig. 1..-In order to bring the 'ladle to the proper height to enterthe opening of the furnace withoutl interference in this particular case, the adjustable 'track section 16 has been elevatediby moving tlie leveriframe 2.3' to the position indicated in Figs. l and 2L VBy vthe elevation of this adjustkabletraclrsection.1G, 'said track vvsection engaging the-treads 'of the front wheels ot' the carriage, elevates the forward 'end of the carriage fand Ithereby elevates the ladle.

YBoth track-sections 16 are elevated atl'tlie same.` time by the vmovement of the leverframe, and the top member of the leverframe-isfelevatedto such. a height that the carriage is'able to pass in under the same.

. W hen the ladle has been advanced into. the furnace andlswung'over.l the pot, theA ladle is. tilted to vthe :position'indicated in dotted lines Fig. vl to deliverthe batch into the pot.; I y f 'i What `I claim'is:

nace pots, the ycombination. with a suitable frame, ofi a v.trackon .said frame, a carriage onsaid .-track, ia' ladle mounted on said,v carriage, means for advancing and withdrawing said carriage, "a movable track# section, interposed in saidf-irst-named track and :means ffoiraising andflowering `said track-section. V i Y.

2. In lapparatus for 'charging glass furnace potsfthe combination fof va suitable vframe, of a track onsaid frame, a carriage on said ltrack wheels von said carriage, a ladle-mounted on said carriage, means for advancing and'. Awithdrawing said carriage,

first-named track, and means lfor raising 'andk lowering saidinembers simultaneously.

4e. In apparatus l'or chargingvglass furnace pots, the'coin'bination with `a suitable frame, of a track on said frame, a carriage on saidtrack, a ladle mounted on said riage, a movable track-section comprising parallel members, 4pivotally mountedarms I engaging said members, bars connectingtsaid arms, and means Jfor moving said bars simultaneously whereby y'said track members are raised and lowered.

5. In apparatus for charging glass i'urnace pots, lthe combination with a suitable frame of a trackonrsaid frame, -a carriage on said track, a ladle mounted on said carriage, a movable track-section comprising parallel members interposed /in Vsaid .firstnamed track, elevating mechanisnna leverframe, connections between saidlever-rame and said elevating mechanism whereby said parallel members are raised and lowered simultaneously, said lever-frame spanning said track above said carriage.

f6. lIn apparatus for charging glass y'faire` nace pots, the combination .with .a suitable.. Y.

frame, 'o'fatack kon said frame,a 'carriage kmounted on said track, a 4Ltiltable .ladile'r f' mounted on said carriage, movable.'t'r-acksection kcomprising parallel members movable up and `down in -slOtsfOrmed in said track, elevating mechanism, an `operating lever, and'connections betweenvv said elevating mechanism and said.A voperating Elever whereby said members are raised and 'lowered simultaneously.

I In testimony whereof, I, the said FRANK E. TnoU'rMAN, have Yhereunto set my hand.
