COALlNG DEVICE FOR RAILWAY-TRAINS.

SPECIFICATION forming part of Letters Patent No. 437,735, dated October '7', 1890.

Application filed April 10, 1890.

To all whom it may concern:

Be it known that I, EDWARD A. TRAPP, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Devices for Ooaling Railway-Trains, of which the following is a specification. 7

The invention relates to improvements in coaling devices for railway-trains; and it consists in a structure embodying elevated compartments or receptacles provided with doors and a discharge spout or chute suspended from pivotally-secured bars or straps and adapted to be swung outward in either direction, so as to be brought in line with the door of either compartment, the one discharge spout or chute thus serving to direct the coal into the tender of the locomotive on either track of the road-bed.

The invention consists, further, in mechanism for holding the doors of the elevated compartments closed while the discharge chute or spout hangs downward at rest centrally below said compartment, and also in mechanism for closing the said doors by the movement of the discharge spout or chute to its normal position after a discharge of coal has taken place. Upon the discharge-chute being swung by the fireman or engineer to one side or the other, so as to come into line with the compartment adjacent to the track on which the tender is in waiting, the upper edge of the chute will move before it, the mechanism holding the outlet-door of said compartment closed, and permit said door of its own weight to fall open and discharge the coal, and upon the discharge-chute being permitted to return to its normal position it will engage the mechanism which previously held the door closed and cause it to return to its former position, closing the door and in that condition holding it, so that the compartment maybe again replenished with coal. After the door-closing mechanism has been returned to its position against the closed door it is automatically released from the discharge-chute, which then hangs freely, and may be swung in either direction, as necessity may require, by the fireman or engineer.

There are two elevated compartments em- Serial No. 347,374. (No model.)

ployed-one for each trackwhile one discharge-chute serves for both said compartments,being capable of being broughtinto line with the outlet-door of either and of closing said door after the discharge of the coal. The elevated compartments will be secured on a frame centrally over the space between the tracks, and the discharge-chute when at restwill hang directly downward, so as to aiford the necessary clearance between them and passing trains, as indicated in the drawings. A supporting-rod is provided by which the chute may be sustained without manual aid in the position given to it by the fireman or engineer for the discharge of the coal.

The mechanism connected withone of the elevated compartments is a duplicate of that provided for the other compartments, and hence while it will usually be more expedient to employ both compartments the invention is not confined to a structure having the two elevated compartments, since where a single track alone is used but one elevated compartment will be necessary.

Referring to the accompanying drawings, Figure 1 is a side elevation, partlyin section, of the coal-chute embodying the elements of the invention, the discharge end of which is shown in position to discharge the coal into the tender of a locomotive. Fig. 2 is an end view of same, the discharge end of the chute in this instance being illustrated in its normal position and not in actual use. Fig. 3 is an enlarged detached side elevation of a portion of the chute, illustrating the discharge portion thereof in a partly-elevated position. Fig. 4 is a detached end view of same; and Fig. 5 is an enlarged central vertical section of a pivoted casting for retaining the lower end of the supporting-rod connected with the discharge-spout, the section being on the dotted line 5 5 of Fig. 6, which is a top view of said casting.

In the drawings, A designates a platform located between the tracks of an elevatedrailroad structure, and B denotes a superstructure or frame, to which is secured the sheet-metal coal-chute, consisting of the receptacles or compartments G D, which have outwardly-fiaring mouths E F, and forming at their opposite outer surfaces segmental sections on which the discharge-spout G may be moved. The receptacles or compartments D are connected and sustained by the braces H I, and contain between them the horizontal aXle or shaft J, upon the opposite ends of which are hung the swinging rods lettered L M N, respectively, the rods M serving to sustain at their lower ends the discharge-spout G, and the rods L N respectively serving to sustain the means (hereinafter described) for closing the doors P Q, hinged to the outer portions of the compartments or receptacles C D. The doors P Q are hinged at their upper edges, as shown in Fig. 1, and are held in a closed position by the contact of the roller R, (see Fig. 2,)which is mounted on the transverse rods S, connecting the lower ends of the swinging rods L N,

- respectively.

Upon opposite ends of the rods S are secured the levers T, the longer arm V of which has a hook-shaped end, while the shorter arm W thereof operates in the nature of a cam to lift the hook-shaped arm V from the pins X of the discharge-spout G when the latter is at its lowermost position, which is that illustrated by dotted lines in Fig. 1, at which time said discharge-spout G is at rest and free to be moved in either direction. The releasing of the hook-shaped arm V of the lever T from the pins X of the discharge-spout is efiected by the arms W coming beneath the pins Z, secured to the receptacles O D, the effect of said pins being to hold the said arms W in a depressed position, and thereby to drive the hook-shaped arms V upward from the pins X. The two positions of the lever T are illustrated in Fig. 1, the lever T on the compartment D being shown with its arm W restrained by the pins Z and the hook-shaped arm V elevated free of the pins X, connected with the discharge-spout G, while the lever T, connected with the arms L of the compartment 0, is represented with the cam-arm W released from the pin and turned upward by the weight of the hook-shaped arm V, the latter being depressed in position to engage the pins X as soon as the discharge-spout G is freed andallowed to return to its lowermost position centrally between the compartments 0 D. The purpose of the engagement of the pins X with the hook-shaped arms V is ,to insure the downward movement of the rods L and roller R with the discharge-spout G, and thereby to effect the closing of the doors P Q simultaneously with the removal of the discharge-spout G from over the tender of the locomotive. Within the discharge-spout G are provided on opposite sides the fingers a b, which during the downward movement of the chute come into contact with the doors P Q and start them on their closing movement preparatory to the roller R completely closing them.

It will be observed that but one dischargespout is made use of for both of the compartments 0 D, this spout being suspended between the lower ends of the rods M in position to be swung in either direction in line with the doors P Q, so that it may be utilized to feed the coal to the tender on either track of the road. In Fig. 1 the discharge-chute G is illustrated in position to discharge coal into the tender on the left-hand track of the road, while in said figure I have also illustrated a car on the right-hand track of the road, the purpose of doing so being to disclose the relation of the coaling-compartments C D with the position of the passing trains.

The discharge-spout G is provided with handles d for the convenience of the fireman or engineer, and is also provided with the sup porting-rod e, which is bifurcated at its upper end and pivoted to the lower portion of the said discharge-spout G, the lower end of the supporting-rod 6 when at rest being per-'.

mitted to hang in a vertical position, as illustrated in Fig. 1 by dotted lines and in Fig. 2 by full lines.

Upon the platform A is swung, upon the pivots f, the casting g, one half of which is shown in section in Fig. 1 and the other half in full lines, said casting. being open through the center and having between its opposite sides the rollers 71. 2' and h z", the former being at the upper end of the casting and the latter at the lower end of same, as shown more clearly in Fig. 5. The platform A is cut away at its center to permit a free swinging movement of the casting g on its pivots f, which are mounted in the upper end of bearings of usual form. The lower portion of the rod 6 is located between the rollers h 'i and h i, as shown by dotted lines in Fig. 5, and is capable of vertical movement. The purpose of the casting g is to retain the lower portion of the rod 6 without interfering with its movement under the direction of the dischargespout G and to firmly support the lower end ofsaid rod-when said spout is in its upper position, as shown in Figs. 1 and 5.

The spout G and casting g, being hung on pivots or loosely swiveled, are capable of being readily moved in either direction, and hence the engineer or fireman upon arriving at the platform A may readily take hold of the handles d or handle an and swing the chute G to its upward position, this act operating to draw the rod 6 upward through the casting g until its lower end has passed upward beyond the lower rollers 77. 7 the casting in the meantime turning on its pivots f under the pressure of the rod 6 against its rollers, so as to assume an inclination through its center in line with the gradually-increasing inclination of said rod. As soon as the rod 6 has passed upward a sufficient distance to bring its lower end above the rollers 71. v) and the bottom w of the castingthe latter will then be left free to turn on its pivots, and will consequently swing back to its normal position and leave its said bottom or fiangebeneath the lower end of IIO the rod 6, as shown in Fig. 5, in which position it will firmly support the rod e and discharge-spout G. When the fireman takes hold of the rod 6 preparatory to coaling, he throws it upward with the discharge-spout with sufiicient force to cause the lower end of the rod 6 to pass up into the interior of the casting g, and at this time the casting swings back to its former position,so that its bottom will be in place to support the lower end of the rod e as the latter settles back after its upward force has been spent.

The casting g is provided at its opposite edges with the foot-treadles to, which are used in releasing the lower end of the rod 6 from the interior of said casting. When the rod 6 is in the position shown in Fig. 5, it, may be released by simply pressing on the treadle to at the left-hand side of said figure until the open bottom of the casting is in line with the rod 6, at which time the rod will slip downward between the rollers hi and 77/11 and assume the position indicated by dotted lines, the casting gradually turning on its pivots to its former position. The lower end of the rod e is provided with aroller to faoilitateits movement along the bottom 10 of the casting g.

The upward movement of the dischargespout G, according to its direction, brings the buffer 01. against the shoulder t of the arm L or N and moves said arm upward beyond the doorP or Q, permitting the latter toopen and the coal to escape into the discharge spout or chute G. After the coal has escaped from the discharge-chute G the fireman or engineer at the platform A by pressing on the treadle to may cause the flange portion of the casting g to pass beyond the lower end of the rod 6, at which time the said rod will slip downward between the rollers h i, and the chute G will return to its normal position between the compartments O D, and, through the pins X and hook-shaped arms V, close the doors P Q in the manner above described. The inner or facing sides of the compartments O D converge downward, as shown in Fig. 1, and in this position aid in directing the coal into the discharge chute or spout G.
