Bei-it; known that 1 WILBIAM, R. PENDRY, 'a citizen ofthe United States', and resident ot'- GleVeland, in. the county of Cuyahoga and State of Ohio,` have inventedl certain newand useful .Improvements in A Loading Chutes,l of Vwhi'clr the following is a specification. y f .This invention relatesto apparatus used in Vtra'nsfer-ring coke,-fcoa'l Vor similar bulky materials by gravity froman overhead coriv'eyer;I b'jnsor other place of supply. intoa carter similar receptacle;- One@ object ofthe inventionfis the provisionlzof coke handling.' apparatus having an adjustable discharge chute ofimproved construction, whereby the materials being liandledi` are l'oaded into a carl or the; like with a minimum: amount of breakage'.

Another ect .off the invention is; to provi'dedischarge chute; adapted' tof yregulate and retard the.- flow ofi materials theretl'i'roughE so as: to: lessen they' velocity at which the materials are discharged 'from' the chute.

Another objectgof my inventionl is the provisioni of a'V discharge' chute having novel means whereby the flow of materialsthereinis controlled, and at desired intervals is SOPPdL* Vfurther; object sof: the invention isntfo provide adischarge;y chute having! 4im roved means: whereby the: materials disc arged therefrom are leveled within acar or other -reeeptacle andl .spilling of vthe Vmaterials lover the sides'. of the receptacle istlessenedy and overcome.' Y

fstillv further objectief this invention 'isf the provision of discharge chute havi- `ing improvedl mea-ns1 whereby abrasion of the chutewby the'materials handled thereby is avoided and largely overcome.

' Furtherohjects and' advantagesofrmyinvention will bebrought out in' the' following? specitication and appended claims, and are illustrated in the accompanying drawings, in Whiche Figure l is a side elevation showing a coke screening mechanism having a discharge chute,embodying my invention, arranged for use therewith in accordance with the invention.

The terminal or discharge sek f atiltingopenend troughll leadin'gtherefrom. andanA adjustable c'lischargel chute B` end of the bottom of the chute B extends upwardly at a sharper angle than the other` portion of the curve, thereby forming a recess or pocket l5 in the bottom of the chute, which is one of the essential features of this invention. f

A cross bar 16 secured to the up er edges of the sides of the chute Bis a apted to in the recessl. ,3

be operatively connected to one end of the cable `17 of a hoist 17, the hoist, which may be of any suitable design, being provided for raising and lowering the lower end of the chute B. i, Y. f I .4

The chute B preferably'islined with tiles 18 to prevent wear by the abrasive adlion of the conveyed material, and binder bars 19 are arranged transverselyv at the opposite ends of the' bottom of the chute to hold the Y tiles 18 in position.

My improved chute especially designed for loading coke, but it will be apparent that it may be used for handlingmany varieties of material other thancoke.

The operation ofthe apparatus 1s as fol- The coke is discharged from a conveyer into" they upper end of thef `hopper 4 `and passes vdownward ,through the legs `6 and 6 to `the':revolving` screens 7 and 8l The screensl deliver the large coke to the hopper 10, from which tliecoke passes through the trough 11 to the dischargechutelB. l Small pieces of coke will accumulate in the low point 15 of the chuteV B. lThe small pieces of coke vwillggatherinv and fill up theY recess or pocket 15 ofthe chute B, serve to engage the.v large coke passingtherethrough, thereby checking the velocity of the traveling coke 'andcauSing' Ait to fall .lightly into the car being loaded,` thus wlessening and preventing further breakage and permitting the coke. to pilel or. `heap up in the car, forming ai good top load, rather than bounding off over the sides, as is the result. whenf using the old style gravity chutes and resulting high velocity. y

' -f f :When the -car has been`V filled, the hoist "1.7". 40

is "sethin vmotion Aand Ythe chute` section B raised,thus-cutting off` or preventing further discharge oficoke until a new car isin position, when the chuteBr is .again lowered tofits discharge position@- 1 1 n L? vOne off the mostimportant advantages of my ,improved chute is the checking of ther velocity of dischargeo-f thecoke by acush. ioned retarder made up of the coke particles '.wItfwill be readily apparentthat various modifications lin thefdesign lof thisl device may bemade in` order toadapt it to various uses and Vforv handling various materials, within the scopeV of the appended claims, without departing. from the spiritI of 1my invention; t v
