ASSIGNOB T0 ANTI-IRAGITE. SEPA- RATOR COMPANY, OF I-IAZLETON, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA LOADING GHUTE Application filed July 15,
This invention relates to improvements in loading chutes which are adapted to be pivotally mounted and swung to different angular positions as the pile of material discharged thereby accumulates.
In a copending application Serial No. 37 5,500, filed July 2, 1929, I have shown a pivotally mounted chute with adjustable retarders therein arranged to be moved upon pivotal movement of the chute. The present invention relates to further improvements in the type of chute shown in my prior application. The invention will be apparent from the following specification when read in connection with the accompanying drawings in which: I
Fig. 1 is a side elevation showing my improved loading chute in full lines in the position it assumes when topping off a pile of coal in one end of the hopper bottom car. The same view illustrates in broken lines the position assumed by the chute when starting to load the car;
Fig. 2 is a plan view of Fig. 1 with a portion of the coal storage pocket shown in section;

. Fig. 6 is a vertical longitudinal section on line 66 of Fig. 5 viewed in the direction of the appended arrows;
Fig. 7 is'a View similar'to Fig. l, but showing the chute in full lines in the topping off position and in broken lines in non-operative position to permit the free passage of cars thereunder;
F ig. 8 is a longitudinal section on line 8-8 of Fig. 7
Fig. .9 is a transverse section on line 99 of F 7.
Referring in detail to the drawings, 10 represents a coal storage pocket having an outlet part 12 adapted to discharge coal into the upper end of the loading chute indicated asa whole-at. 14. The chute includes a hood =16whaving aside entrance opening through 1930. Serial No. 468,029,
which the extremity 18 of the part 12 extends. Within the hood, there is a curved baffle or guide 20 which causes the incoming coal to change its direction, as indicated'by the arrows in Fig. 8, so that the material will flow between the retarder members 22.
The chute 1 f is pivotally mounted for swinging movement as a whole on trunnion members 24 and 26. The trunnion member 24: comprises a stud secured to the hood 16 which extends to a bearing aperture formed in a plate 28. The trunnion member 26 as shown in Figs. 5 and 6 is a substantially U- shaped member, whose upperextremities 30 are bolted or otherwise secured to brackets 32 secured to fixed plate 3 1. The U-shaped trunnion member 26 is seated in a curved ring 36 secured to the hood 16 of the chute. The chute includes plates '38 and &O which are held in spaced relationship by skeleton frame members 42, the latter being secured to longitudinally extending angle bars 44: and 46 carried by'the plates 38 and 40, respectively. The several pivoted retarder members mounted between the plates 38 and 4:0 jointly form the side enclosures of the chute. Thus it is clear that because of the converging arrangement of their pivots the retarder can effect a variable and gradual restriction of flow area of the chute, such restriction in area increasing from the inlet end of the chute toward the outlet end thereof. Y 1
Between the plates 38 and T0 are mounted the retarder members 22 above referred to.
58 with a crank arm 60 formed on one end of a rock shaft 62 journalled in bracket 64 secured to the hood 16. The shaft v62 carries another arm 66 having an end 68 which projects through a cam slot 70 formed in the fixed plate 28. This cam slot has dwell portions 72.
and 74 which are approximately concentric with the trunnions or pivotal mountings for the chute. These dwell portions in the cam are joined by the active portion 76.
When the chute 14 hangs down in the ver tical position as shown in dotted lines in Fig. 1 and full lines in Fig. 4, the end 68 of the arm 66 will occupy the dwell portion 70 of the cam slot and the retarding members will extend an appreciable distance inwardly as shown in Fig. 5. As the chute 14 is swung on its pivotal axis on the trunnions 2426, the shaft 62 will be rocked by the active part 76 of the cam. This will shift the actuating bar 52 which will in turn rock the retarder members outwardly to a position approaching that shown in Fig. 8. As thus arranged, it is clear that as the chute is swung from its vertical toward its horizontal position, the retarders are moved gradually to positions where they exert a gradually eel-easing retarding action. This is desirable because as the chute approaches the horizontal the component force of gravity becomes less and less.
Reference to Figs. 5 and 8 will indicate that the shafts 48 for supporting the retarders are located along lines m n and 0 which converge toward the outlet end of the chute. This arrangement is desirable for it provides a gradually decreasing area toward the outlet end of the chute. This permits a restriction in the flow near the bottom of the chute, such reduction of flow allows the coal to substantially fill the chute so that the material flows therethrough in a more or less continuous or unbroken stream. Such continuous flow minimizes the breakage.
Spaced from the plate 40 of the chute there is located a topping-off chute 78. This men her is provided with a flange 80 extending along one edge thereof, which is secured to the frame members 42.
In operation, a coal car is located below the coal pocket and the chute 14 is lowered from the horizontal inoperative position dotted in Fig. 7 to the dotted position of Fig. 1. In this position, the retarders 22 will be at such an angle that a maximum retarding action is secured so as to prevent rapid flow of coal such as would cause breakage. As the pile grows in the car, the angular position of the chute is gradually changed by pulling on the cable 82. Such pulling movement swings the chute on its trunnions 24 and 26 and automatically alters the position of the retarders 22 so that they exert less and less retarding action as the chute approaches the horizontal. The topping on chute 78 provides for simultaneous discharge of material from an auxiliary outlet 84 in the coal pocket.
This outlet 84 is controlled by a suitable gate 86 which is only opened when the loading chute 14 reaches its elevated position. At this time, the angular inclination of the load ing chute is such that the material wi l travel at a slow rate and no appreciable breakage will occur. The topping-01f chute also permits delivering the material on top of a pile previously accumulated. That is, after the pile has been built up to a maximum height by discharging material from the chute space etween the plates 38 and 40, additional material can be piled up without breakage by causing it to descend slowly along the topping-0E chute which is mounted in spaced relationship with the chute 14. This topping ofi' chute is provided with a baflle or deflector 88 as shown which is adapted to retard the speed of the coal and also to alter its direction of flow so that the coal will be piled in the center of the car.
Various modifications and substitutions of equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.
What I claim is:
1. A lowering chute for coal and similar materials comprising spaced plates with pivotally mounted retarder members between them, a topping oif chute secured adjacent one of said plates, an operating bar for said retarder members shielded by said topping ofi chute and means for pivotally supporting the aforesaid parts.
