Referring in detail to the drawings, 10 represents a bin receiving coal from the breaker.

The dust and-fines are adapted to be rejected tliroughacliute 16leadingto a waste pile.

Our improved c'ar loading chute indicated as awhole by numeral 18 is swiveled or pivct-ed relatively to the neck portion 12 of the v The neckportion of the bin makes a I bin. quarter turn as shown at 20 in Figs. 1 to 3.

The lower end of the bin isformed At the end of the neck there is a rod 22 carried in brack-etsf% and forming a pivotal or hinged support for the chute 18. 4

The chute 18 is substantially rectangular in cross section and is of hollow form as shown in-Fig. 6.-- v

T Located within the chute we provide a retardingmember indicated as a'whole at 28, this member being formed of a top wall and downwardly extending side walls These sidewalls, as shown clearly in Fig. 5, are of undulatinger Zig-zag f orm. The

heightof the side walls 32 (if the retarding member isappreciably less than the height I of the side walls 34 34 of the chute 181 a Suitable guide strips 3636 maybe riveted, welded, cast or otherwise secured near the upper end of the chute. I Similar guide strips 38 38 are suitably secured near the lower end of the chute. 'These are merely retaining guides and make a very loose sliding fit withthe ends of the retarding member.

' tionthe retarding member may be-automr Inasmuch as the chute is inclined to the horifzontal the guide strips 3838 prevent the retarding member from sliding endwise.

VJ hen the chute is in its relatively steep incl ned position as illustrated in full lines in 1 igs. 1 and 2,it is supported in part by acable having a ball 42 01" other enlargement secured thereto; Thecable L0 passes through an opening which-as relatively narrow, as

indicated at 44 and providedwith an enlarge ment 46', of a size suificient to permit the ball $2 to pass therethrough at certain times as here .i'termore fully explained. The lowerext nity oi" the cable i0 is secured to an ear i8 rorm'ed on theretarding member.

So long as the ball 42 lies below the will move both the chute niemberQdabout therod as a pivot.

When they chute isin the steepaugular positions itis desirableto have the-retarding member in the operative position illustrated in Figs. 4 and 6. This Wil'tend to retard the rapid flow of coal so to minimize breakage of the lumps which will naturally iall fronrthe end of the chute at arelatively slow speed; However, when tl chute is inclined at a more gentle angle, for. example, when swung to dotted position of 2 and 4; the retarding action is undes rable; In this posi .ticallylifted outof the way to the position, for

example, as illustrated in Fig. 7. This may, be accompllshed automaticallyas hereinafter described by the ball 42 slipping from under the narrow portion 4 oi the opening foto theenlarged portion where-it is free to pass through the opening.

' ball-is free to slip through thehole tda relative movement between the chute and theretarding member willtake place.

. the ball will-not slip through without move-- designed that the ball 42 by theworkman striking a blow on the cable. For exampleyit may be-hit with a shovelor with a club. Usually there will be; a workman in the car assisting in trimming the pile and when he observes that the coal is flowing at tooslowe rate because of the retarding member. itis merelyf necessary that he strike the cable so as to permit the retarding member to move to inoperative position. It oi Y course understoodthat the weight of the chute will eftect'a relative movement between it and the retarding member wheneverthe ball 42 slips through the enlarged hole 46.

gvsaaoz For automatically causing the ball 42 to slip through the enlarged hole 46 and thus cause the retarding member to move .to 1Il-- operative position when the chute attains a gentle angle, we provide a bail-like member 56 pivoted at to a fixed support as shown in Figg l. The bridge portion 58 of this baillike member normall bears v:treel a 'a'inst the cable-4O when the chute-ism the steep inclined pos tion. Vfhen the chute 1S hfted" to a gentler angle the bridge portion 58 pushes thecable'4-O to the left in a and when the chute reaches predetermined position dotted 1n Figlt the ball l2 w ll slip through Thus the retard ng member will be lifted relatively to the chute and the coal can flow re'ely. a

In a modified arrangement insteadof depending on the ball or other devices carried by the cable for holding the retarding memher in its operative position at certain times and-permittingits movement to non-operative position at other times, the chute isprov-ided with a plurality of latehes60 pivoted at 62 on brackets 64 secured near the ends of the'ohute. Springs66surrounding the pivot,

studs 68 on whichthe latches are mounted tend to press the latches inwardly to the.position of Fig. 9 where their teeth 70 overlap the top surface of the retarding member. If desired, indentations 72 and 7d may; be

formed in the retarding member for coaction with the teeth 7 O as shown.

Withthe arrangement. of Figs..9 and 10 it is clear that the latches may occupy the positionoif Fig. 9 when the chute is inclined ata steep angle. Thus the retarding'memher will be operative to impede the travel of coal flowing through the chute so as to pre-' vent breakage which might be occasioned by too'rapid a flow On the other hand, when the chuteis movedto the more gentle angle the latches can be released and thus the retarding member. will be movedto its non-operativeposition.--

Referring to'Figs. 11 to 13 inclusive, we have shown a modificationin which a retarding member is adapted to bemoved ina' direction at right anglesto a chute 82 through a longitudinal slot 84, which is of zig-Zag or serpentine form following theshape of retarding member 80. In this embodiment of theinvention. the retarding memberis supported on alongitudinally extending bar 86, which, at its ends ,is secured to cross pieces 88, The cross pieces88 are secured to bars 90, which are slidable in bearings 92 carried by the sidewallsof the chute 82' :The bars 90 at their ends are connected by tie bars 94.

. Theseveral bars'QO, 94aand 86 forming sort-of they may bemoved by a straight pull exerted by workmen. It will be understood that when the retarding member is lifted to its s highest position with relation to the chute that the maximum retarding action is secured. By lowering the retarding member] the retarding action may bevaried and when berin non-retarding position when said chute the member 80 is in its lowest position it will exert practically no retarding action and in the extreme position the upper endoi the retarding member will lie practically flush with the bottom surface of the chute 82. This retarding member 80may be moved to various intermediate positions by manipulating the cable 98 as will be understood.

While we have describedquitespecifically the details of the embodiments of the invention herein" illustrated it is not to be construed that we are limited thereto since va-' rious modifications and substitutions of equivalents may be made by those skilled in the art without departure from, the'invention as defined in the appended claims.
