DISCHARGE CHUTE File'd July 2, 1929 SreflSa FRANK IPARDEE, OF HAZLETON, PENNSYLVANIA, .'ASSIGNOR TO `ANTHRACITE SEPARATOR COMPANY, OF HAZLETOFL; PENNSYLVANIA, `A. CORPORATION OF PENNSYLVANIA vDIsommen; CHUTE This invention whilev not YVlimited thereto relates'to improvements in vchutes adaptedl particularly for transferring material from bins to railway cars.

5 'Tn the handling ofcoal it is important that the'lumps move slowly .in transit from the bin to their final resting place. This is to avoid breakage or formation of fines which have little or no sale value. My improved discharge chute includes a serpentineor sinuous retarding member which tends to slow upthe lumps travelling from'the bin tothe car.l This member prevents breakage or production of unsaleable fines;

trated, I provide two telescopic sections. During the initial stage of loading thetelescopic sections are expanded and the lumps of coal leave-the chute in the approximate zone which is tobe their final resting place in the railway car while in transit. As the car fills: up the sections are collapsed toas to shorten the distancebetween the end of the chuteand the growing pile inthe car. Thel 5 car is also adapted to be moved longitudinal lyso as to permit progressiveV loading lengthwise ofthe car. n Y

l*The improved chute is so .designed that the two parts when collapsednest together, the 3Q retarding member of one party of the chute being accommodated ina other chute. Y I f The invention will'be fully apparent from the following specification when read in vconslotformed in the 3. nection with the accompanying drawings and the features of novelty will be deiinedvwith particularity in the appendedclaims.

. Referring in detail to the drawings, 10 rep V resents somewhat diagrammatically an ordi-A nary coal car adapted to be moved along the track siding 12 located adjacent Ya storage or coal breaker bin 14. This bin is .provided with the usual form `of outlet or neck portion 16 to which is secured my improved discharge chute indicated generally at 18. This chute .as shown-consists of kan upper section 20 and a lower sectionh 22. The lower section embraces and is adapted to telescopically engage the upper section. Y

The underside of the upper section is providedwith a foraminous portion 24 adapted Y to permit the passage therethrough of'dust or fineswhich escape to a discharge chute 26 leading to a! waste pile. The lower section 22 is formed with an interrupted portion 28 which, when the` two sections are collapsed,`

coal from a bin 14 the sections 20 and 22 willV be extended position, as illustrated in Fig. l. As the pile of coal stacks up in the car approximately to the position indicatedV by the dotted line m the railway car will be moved endwise so as to buildup the pile in the corner from substantially one end oit the car to the other. With this arrangement it willV be understood that the v'coal falls a shorter distance from the end ofy the chute tothe car thanwould bethe case the chutek were only half as long.

Asthe coal' begins to accumulate in the bottom of the car and in the corneropposi'te the-endV of the chute it is necessary to shorten up the distance. This can be don-e by'moving the' extended chute bodily back toward the bin-14 along the neck portion lzf As the car begins to. fillV lup the chute Vcan be materially shortened by turning the Vlower section k22 approximately 180 degrees with relation toVV the section 20 whereupon the lower section can be pushed back or telescoped on the upper section. The lower section of course can occupy a great number of positions so as to permit the pile tobe progressively` built up in the car as indicated by the dotted lines m and m2. When the section 22 'is retracted or partially collapsed it willbe understood that the retarding member 36 of the lower section passes freely through the slotted portion 30 and the upper section and is accommodated in the-space above the partitionwall 32.

Whenthe section 22 is fully collapsed on theY section 2O the interrupted or ycut-away portion 28 registers with the foramm'ousportion 24 so that the escape of fines to the vdischarge chute 26 is in no way interfered with.

Ity will be appreciated.y byI those skilled in theart'that. the improved discharge-chute describedv herein enables coal handlers to vprogressively load the railwaycoal cars in such a way that thefreeoow of coal lumps from` the end ofthechute to the growing pile is so shortened that aiminirmumbreakagc Vof lumps will take place. Thus by use of the Y member of serpentine, sinuous or undulating -form 1n which the crests as welly as the hol'- lows are rounded or curved vas shown. The curves maybe arcuate or otherwise and the surfacesjoining the curved crests with the curved hollows maybe either straight or curved. The provision of a retarding member of this shape influences the travel ot material through the chute so that it progresses en masse with a slow wave motion. Thus the coal lumps leave the end of the chute at a relatively slow rate of speed thereby avoiding ithe breakage or the production of unsalable nes. l While I have described quite specifically the details oit' the embodiment of the inven tionherein illustrated it is not to be con` strued that I am limited thereto since changes in the arrangement and Vsubstitution oi"V equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.

1. A discharge chute of the character'described 'comprising a pair of sections intelescopic' engagement, respective retarding members secured to said sections, one of the sections: havingl an Yinterrupted portion adapted: to .accommodate the retarding member of' the other section when the two are collapsed.

.. 2. A discharge chute of theY character described comprising a pair of substantially cylindrical sections, one section having longrtudinal slot extending lengthwise ofthe top thereof and' a longitudinal partition substantially central thereof andA a retarding wall between.v said partition and the lower inner Vsurface of said section, the other section embracing Vthe first mentionedk sectionand having a retarding member adapted toV pass through said slot above said partition when the two sections are collapsed.

'1 3. A discharge chute of the character deascribedy comprising upper and lower substantia-ily cylindrical sections, saidv upper section having a retarding memberl therein and hav-` ing a foraminous portion to permit the escape of ineinaterial, said lower section telescopically embracing the upper section and having an interrupted portion adapted to be brought to substantial register with the oraminous portion vot the upper section when'the parts are collapsed.

4. A discharge chute comprising a pair of tubular sectionsk in telescopic engagement, one of'tlie'sections havingian upright retarding wal-l vextending lengthwise thereof and the other section having an interrupted portion adapted to accommodate said retardiug wall when the two sections are collapsed.

y5. A discharge chute adapted to be obliquely disposed, and having an inclined runway surface along which material is adapted to: flow -by gravity, and a sinuous retarding member disposed lengthwise of the chute and extending upwardly from said inclined run- 6. A discharge chute of the character described comprising an obliquely supported tube along the lower portion of which material is adapted to flow by gravity and a sinuous retarding member disposed centrally of the runway portion and dividing it into two longitudinally inclined zones.

In witness whereof, I have hereunto signed my name.

FRANK PARDEE.
