AppIication filed November 26, 1919. a Serial No. 340,819.

To all whom it'may concern .&

Be it known that we, ALGo'r A. VVIGKLAND, of Chicago, Illinois, and FREDERICK K.VIAL, of LaGra-nge, Illinois, citizens of the United 5 States, residing as above stated, in, the county of Cook and State of Illinois, have invented a new anduseful Improvementin I Charging Machines, of which the following is a specification: a I

, This invention relates to chargingdevices forfoundry cupolas, furnaces and the like and has: for its objectbroadly the provision of new and improved charging'apparatus and adapted to place the charge accurately in a desired portion of the cupola, furnace or other receiving apparatus, or to distribute the chargeevenly therein. in n An important object of the invention is the provision of aicharging apparatus ofsimple, efilcient character for feeding a num ber of series ofcupolas, furnaces or other receiving apparatus through the provision of a small amount of equipment. I 7

Another important obj ec of the invention is the provision of a charging apparatus for feeding one or more cupolas or furnaces and requiringa minimum of manual' labor and a minimum number of operators and attendants. I Another important object of the invention is the provision of a charging apparatus which will receive a wheeled truck carrying the material forming the charge andpour the material from the truck into, any of a number of cupolas and from certainaspects of the invention into a single cupola.

,Another object of the invention is the provisionof an apparatus accomplishing these and other valuable results, parts of which will be so constructed and arranged as to render unlikely the necessity of frequent repair, replacement, and readjustment and which a-pparatuswill be power actuated in its several movements and functions. j

Numerousother objects and advantages of the invention will be apparent as the invention is better understood from the following description, which when considered in connection with the accompanying drawings discloses a preferred embodiment thereof.

On the drawings, Fig. 1, is a diagrammatic plan view of a vfoundry cnpola organization of which the charging apparatus embodying our invention is selected for the purposesof illustration, forms a part. a a i i Fig. 2, is a diagrammatic verticahview through the same. i j l, I g; Fig. 3, is an end view ofjthe charging apparatus or conveyor embodying, our pres ent invention; ff 1' ,Fig. i, isaside View of thesaine; and

Fig, 5, is a front toback vertical section, For. the purposes ofiillustratingthe invention we haveshown in Fig. 1 a schematic layout of a possible cupola organization in a foundry and on this figure reference characters 11 indicate the cupolas. In front of these Cupolas are provided tracks 12 extend ing in frontof the series of cupolas and on which moves a charging apparatus or conveyor Delivery tracksl lfor wheeled trucks are provided, as: are also storage tracks 15 in any suitable number and in any suitable arrangement. A crane 10 is pro? 'vided to deposit the truckscnthe tracks 14;. Viewing Fig. 2 it will be noted that the cupolas are in the present instance of relativelylarge dimension and provided withthe chargingopenings 16 adjacent the charging tracks 12, j The charging tracks as has been stated extend past the cupolas and the charging apparatus is adapted to receive and carry the trucks or containers containing the material to be deposited in the cupolas and to dump such material from'said trucksor containers by tilting them to a pouring position as indicated in'dotted lines in 'Fig. 2. As willbe presently. mOre fully understood, the charging apparatus is adapted to move the. trucks when tilted and pouring out the contents backwardly and forwardly in the cupola and from side to side, and incombinations of these movementsas occasion may require orrender desirable. I I j The charging apparatus comprises a main conveyor frame of substantial I-beam con struction and 'cqmprising side I-beams 21 and end I-beams' 22 suitably connected to- ,gether and braced and supported on shafts side wings 28 of heavy material and secured upon the tops of the end I-beains. The side wings are provided with cross shafts 29 extending between them and also stub shafts 30, said

shafts

29 and 30 carrying rollers 31 between which is mounted a frame laterally movable of the charging truck and toward and from the cupola. This frame comprises I-beams 32 engaged between the rollers at each side and connected at their ends by I-bea-ms 33, additional I-beams 34 arranged parallel to and connected to the I-beams 32. are also provided, the connections being by castings 35 disposed within the I-beams 32. These last mentioned I-beams support a pivotally mounted truck pp on which he r k 36 m y e d posed. This support comprises two. side members 37 mounted nearthe ends adjacent the eep la e 2 th p ot. ha 8 a d ?et the other ends connected by, a cross, member 39, which in; normal receiving position, rests upon the I-beam 34. The track: frame is thus pivotally mounted on the shaft38- and carries at its top z-bars 3.9 which form the rails. These Z-bars are turned: up at their ends at 41 to provide curves into which the forward wheels of the. trucks fit, when the tilting frame is tilted about its pivot shaft 38 preventing the truck running off therails. It is. intended that this pivotal movement maybe as mueh as. 9.0. degrees and-to prevent j the truck falling away from the. track, angle bars 42 are secured in the upwardly extending flanges 43 of the-Z,-ba;rs and these angle n adep e t bee seged by e n r' ting hooked castings. 44fcarried on the jourm l e ie 4 of herucks Thera ls. t rm d by h 1 e. ?s dthe ti tin r m a l i ely ho t end, exte dm fely hr u eu a is an e mply s i iti ht teeeeommed t the tru k- T e Z-bar m ls. r gi ter wi h. il se tio s 6. carried. 1 th .-heam 3, 1 su tabl t es 4 .1 an hese r lsv 4 este df n pe tiea ece h t uek fr m he: feedr hg 0 7 pply rai s whe th apparatus is arranged areeeir nsP eit m A hooked. hre ket 3 may Secured to th ar s de of he ei *2 ,,vr ieh is at th r a e di ten e, rom. he upa .0 he like, by any ui ab e means, 5 1th by bol s e d. e breeket 1 3) e se'eured n the. d Wings 28 of the ame by any u tabl means, e teh' a by belt 86. h like, Whie is adapted Q' ngag he eked b ack t. .3, to ure. aga nst; a tipp ng of the hargin appar tus. .3. when the r ks. 3,6 he vily Few .mee enism iep evided f r r v the nti harging mechanism l ng he e ers ng. acks, f r mov ng the horizent y .me blelframe oward; and e he cupelemechanism for advancing the charging apparatus along the charging track, a motor 48 is mounted upon an extension 49 of the main frame of the apparatus. The shaft 51 of this motor carries a gear 52 meshing with a gear 53 on a shaft 54 having hearings in upwardly extending brackets 55. on such extension. The shaft 54 is provided with a pin-ion 56 in mesh with a gear 57 fast on one of the car wheel or truck wheel shafts of the apparatus. The motor through the gearing described rotates the shaft and propels the apparatus in either direction as may be desired.

The mechanism for moving the horizontally movable. frame. comprises a motor 61 mounted at the side of the apparatus. This motor through a worm and gear drive 62 drives a shaft 63 carrying apinion 64 meshing with a gear 65 upon a shaft 66 carrying pinions 68, said shaft having bearings at 67 in the sidewings, The pinions 68 mesh with racks 69 on the under faces of the I-beams 34.

The mechanism for tilting andlowering the tiltable support comprises a motor 71 supported by a strap. 72 from the I-beams" above a platform :81 supported from the extension 49 in the main frame, one of said controls 82 being shown for the purposes of illustration. 7

In the operation of the apparatus the truck is run across the track sections 46 and I on to the tiltablje support. The charging apparatus is then brought, adjacent the cup ol a in which. the charge is tobe deposited and the horizontally movable frame moved forward into charging position. The tiltable support is then tilted to cause the contents to'pour from the truck and during this pouring operation the horizontally movable frame'inay be moved back and forth, i. e. inwardly and outwardly, of the cupol'a to accurately deposit the material or spread it as may be required. Sidewise motion may also be given the car during the pouring operation by moving the entire char ing apparatus along the charging track. (10mbinations of these two movements may be employed and the pouring accomplished in a circular fashion into the cupola.

It will be manifest that the apparatus is of simple character and caneasily be controlled by a single attendant during the charging operation.

It is though th t he inveht e an m y of its attendant advantages will be apparent without-further description and it will be obvious that various changes may be made in the form, construction and arrangement of its parts without departing from the spirit and scope of theinvention or sacrificing all of its material advantageathe form hereinbefore described being merely a the ferred embodiment thereof. l
