  • the arms 58, 58 and the rollers 59, 59 serve to lock the shafts 14- and 15 in positions in the horns 10, 10 mperative when the gallows frame 33 and the track section 4;"are depressed, or to move the shafts to this position when the gallows frame moves downward, in case they one end to the frame of the track section.
  • a coil spring '66 surrounds the rod 64 between its point of pivotal connection and the yoke 63. The spring tends to normally hold the horns in the position indicated by dotted lines in Fig. 1, and by full lines in Fig. 2.
  • a brake Wheel 67 which is engaged by a brake band 68.
  • One end of the brake band is secured to the frame of the track section and the other end is secured to one end of a lever 69 which is pivotally mounted between its ends on the track section frame at 70.
  • a weight 71 which serves to normally tension the brake.
  • 72 is a chain suitably connected at its upper end to the framework of the dump and connected at its lower end to the end of the lever 69. This chain is of such a length that when the track section 4 is dropped to its lower position it will move the lever 69 with respect to the track section frame sufficiently to release the tension of the brake band.
  • 73 represents a car in dumping position.
  • 74 is a chute for receiving material discharged fromthe car. As the car moves into dumping position the end may be opened manually by the operator, or, if desired, bars 75 may be provided for engaging with suitable lugs 7 6 n the car to raise the door.
  • Fig. 1 As a car approaches the dump it is engaged and stopped at the horns 9, 9. When it is desired to advance the car to dump it, the operator by moving the lever can move the horns 9, 9 to release the car and at the same time move the horns 10, 10 into position to engage the car wheels as the car moves forward under the action I of gravity.
  • the weights 46, 46 apply a gradually increasing resistance to the downward movement of the track section with the result that it is brought to rest in alinement with the track 2 with a minimum of shock.
  • the weights 46, 46 are of such size that they will be lifted by the combined weight of the track section and of a car, but will lift-the track section back to normal position after the car has passed from it.
  • the chain 72 is tensioned and the brake band 68 is released from the wheel 67 and the horns 61 are permitted to be moved by the previously compressed spring 66 to give the wheels of the dumped car an impulse which serves to start the car over the hump of the pivoted track section and downward onto the return track 2.
  • the section is at once raised to normal position by the weight 46, 46.
  • the weights supply a gradually decreasing lifting force which finally becomes practically equal to the weight of the section.
  • the track section is elevated with a minimum of shock.
  • the horns 9, 9 and 10, 10 While the track section 4 is depressed the horns 9, 9 and 10, 10 are held in the position as last described by, the engagement of the rollers 59, 59 with the flanges 39, 39 of the gallows frame. The operator may, therefore, if desiredrelease his hold on the lever 20. As soon as the track section returns to its normal upper position the weight 32 is permitted to act to move the-horns 10, 10 to release the 'car and to move the horns 9, 9 back into car engaging position. It will be observed that the distance between the horns 9, 9 and the horns 10, 10 is somewhat less than the length of a car. As the result of this if a second car moves onto the dump while the first car is engaged by the horns 10, 10 it will be held. a slight distance back from the horns 9, 9. This gives time for the horns 9, 9 to be returned into operative position before the second carreaches them.
  • the advancing car moves first on to the upper slightly inclined part of the track section 4 and finally onto the part which is inclined sharply downward.
  • the car approaches the downward inclined part its wheels are engaged by the horns 61 and the downward movement of the car is first resisted, and then stopped by the combined actionof the spring 66 and the brake band 68 engaging the wheel 67.
  • the car remains in this position until dumped, its end having been opened either manually or automatically, as before described.
  • the operator After dumping, the operator by moving the lever 20 can release another car from the horns 9, 9, which will act to release the pivoted track section to-permit it to drop and the entire operation of the dump will then be repeated in the manner which has been before described.
  • the construction of the gallowsframe is such that when the frame and the pivoted track section are depressed the upper cross member 35 of the frame is in position to engage the bufier of a car. In this way an additional safety device is provided for preventing a car, which may in some manner have gotten past the horns, from running OK the open end of the track 1.

To all whom it may concern:
Be it known that L'G'roncn H. MUELLER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain newand useful improvements in Car-Dumping Apparatus, of which the following is a specification refefe'nce being had therein to the accompanying drawing.
This invention relates to car dumping apparatus of the type in which the car is tilted to an angle such that material within the I car will slide out through an opening 1n the end. More specifically my invention relates to apparatus of the class in which two superposed tracks are provided and in which a car is transferred from one:track to the other by means of a shifting track section and dumped While on the shifting track section. The objects of my invention are to provide a car dumping apparatus of this class having improved means for controlling the movement of the car while it is approaching the shifting track section; improved means for controlling the car into and out of dumping position and improved means for actuating and controlling the shifting track section. Numerous other objects will be apparent from the following specification.
1n the accompanying drawings, .which form a part of this specification, I have shown the form of mechanism which I now preferable. it will be understood, however, that various modifications and changes may be made Without departing it of my invention.
.- awings,

shafts mounted. parallel to and at clined in the other direction and is provided at its upper end With an upturned part 3 for a purpose to be described. it represents a shiftable track section Which is mounted at its forward end upon a horizontal transverse shaft 5 '';having suitably supported bearings 6 and 7 at its ends. The section l is arranged When in its upper position to aline With the track 1 and when in its lower position to aline with the upturned end 3 of the track 2. The section 4: has a part 8 adjacent its pivoted end which is bent sharply downward with respect to the main part of the section. The purpose of this will be hereinafter set forth.
I By preference the rails of the track 1 and of the section 4 are rectangular in cross section and are narrower than the treads of ordinary track rails,
In order to control the movement of cars along the upper track 1 two pairs of horns 9, 9 and l0, 10 are provided. Each horn held at one extreme position by means of coil springs l3, 13. These springs serve as shock absorbers when the horn is engaged by a car wheel.
14- and 15 are tWo horizontal rotatable sides of the track 1. At one end there is provided a transverse horizontal rotatable shaft 16 which is connected with the shafts l4 and 15 by means of pairs of bevel gears 17 and 18. ranged that the shafts 4i and 15 will be rotated in the opposite directions. 19 is an arm on the shaft 16. 20 is a hand lever pivotally mounted at a point adjacent the pivotal support for the is a rod or link connecting the hand lever By means of this ill'lian operator by moving the lever 20 can Qil with the arm 19.

and 23 are upstand" es. actively to the shafts I cause the sinr l is provided with a depending arm. 2
opposite The gears 17 and 18 are so ar- " Mil lever 22 or 23 there is provided a link 25. 26 and 27 are other upstanding levers mounted respectively on the shafts 1t and 15 at points opposite the horns 10, 10. Each of the horns 10 is provided with a depending arm 28 and between each arm 28 and the corresponding lever 26 or 27 on the shaft at the opposite side of the track there is provided a link 29.
By means of the construction which T have described an operator by moving the lever and tensioning the link 21 may rotate the shaft 16 and by means of it the two shafts 14 and 15. By means of the two links 29, 29 the horns 10, 10 are moved from outstanding positions into positions for engagement with the wheels of a car moving along the track 1. Simultaneously by means of the links 25, the horns 9, 9 are moved from positions in alinement with the wheels of a car to outstanding positions out of alinement with the wheels of a car. Preferably a sheave 30 is mounted on a shaft 16 and over this sheave there passes a rope 31 to which is attached a counterweight 32. This counterweight will serve to automatically move the parts in the opposite directions from those which have been described and to return them to their initial pcsitions.
33 is a vertically reciprocable gallows frame forcontrolling the movement of the shifting or oscillatory track section 4:. The frame 33 comprises two side upright members 34:, 34 and top and bottom horizontal cross members 35 and 36. Suitable guides 37, 37 and 38, 38 are provided for the frame. These guides engage with outstanding vertical flanges 39, 39 on the uprights 3a, 34. By means of links 4:0, 4:0 the ends of the rails of the track section 4: are connected with the cross member 36 of the gallows frame. on a suitable framework is a transverse rotatable shaft 41 upon which two sheaves 42, 42 are mounted. Each of the sheaves 452 preferably has two rope receiving grooves. Secured to each sheave and arranged to engage with one of the grooves is a rope 43 which extends downward and is connected with the top member of the gallows frame, preferably by means of a link 44. Other ropes 45 are secured to the guide sheaves 42 for engagement with the other grooves thereof. These ropes extend downward at the opposite sides of the sheaves and carry at their lower ends the adjustable counterweights 46. It will be observed that the construction is such that the counterweights tend at all times to lift the 0s illatory track section. In order that the lifting force of the counterweight may be properly applied, the sheaves 42, are by preference mounted eccentrically on the shaft 41. The sheaves are so arranged and connected that when Mounted above the gallows frameas tamer? the section t is depressed, as shown in Fig. 21,
of the counterweights is applied at a rela tively small moment arm and the weight of the track section applied at a relatively great moment arm. By properly adjusting the size of the counterweights they may be made to approximately balance the track section when it is in upper position. However, when the track section is in lower position the counterweights on account of the changed moment arms will apply a consid erable lifting force.
t7, 4:? are two longitudinally slidabl latches arranged to engage with lugs 48 at the ends of the rails of the track section 4. and to support the track section in alinement with the track 1. At points adjacent the latches 48, 48 are suitable stops 4:9, 49 for engaging the lugs 48 to limit the upward movement of the track section. 50 and 51 are two transverse rock-shafts mounted in suitable bearings connected to the rails of the track 1. Secured to the ends of the rear rock-shaft 50 are upward and forward inclined trip levers 52, having downward extending arms 53. Secured to the ends of the forward rock-shaft 51 are trip levers 54, having downward extending arms 55. 56, 56 represent two links, which areconnected at their forward ends to the latches L7, 47, at their rear ends to the downward extending arms 53 of the trip levers 52, and at points intermediate their ends to the downwardegrtending arms 55 of the trip levers 54. lithe trip levers 5a are .be'ntsuccessively backward and downward and preferably at their extreme ends counterweights At the forward ends of the shafts l i and 15, at points opposite the gallows frame 33. are inward extending arms 58, 58 which carry rollers 59, 59 adapted, to engage with the vertical flanges 39, 39, these flanges being beveled at their lower ends. The arms 58, 58 and the rollers 59, 59 serve to lock the shafts 14- and 15 in positions in the horns 10, 10 mperative when the gallows frame 33 and the track section 4;"are depressed, or to move the shafts to this position when the gallows frame moves downward, in case they one end to the frame of the track section.
The other end carries suitable lock nuts 65. A coil spring '66 surrounds the rod 64 between its point of pivotal connection and the yoke 63. The spring tends to normally hold the horns in the position indicated by dotted lines in Fig. 1, and by full lines in Fig. 2.
At the other end of the rock-shaft 60 there is a brake Wheel 67 which is engaged by a brake band 68. One end of the brake band is secured to the frame of the track section and the other end is secured to one end of a lever 69 which is pivotally mounted between its ends on the track section frame at 70. Slidably mounted upon the lever 69 is a weight 71 which serves to normally tension the brake. 72 is a chain suitably connected at its upper end to the framework of the dump and connected at its lower end to the end of the lever 69. This chain is of such a length that when the track section 4 is dropped to its lower position it will move the lever 69 with respect to the track section frame sufficiently to release the tension of the brake band.
73 represents a car in dumping position. 74 is a chute for receiving material discharged fromthe car. As the car moves into dumping position the end may be opened manually by the operator, or, if desired, bars 75 may be provided for engaging with suitable lugs 7 6 n the car to raise the door.
In operation let it be assumed that the shiftable track section is in'its upper position and that the horns 9, 9 and 10, together with the associated parts have been moved by the weight 32 so that the horns 9, 9 are in position to engage the wheels of a car and the horns 10, 10 are out of car engaging position. Also let it be assumed that there is a car in dumping position, as
shown in Fig. 1. As a car approaches the dump it is engaged and stopped at the horns 9, 9. When it is desired to advance the car to dump it, the operator by moving the lever can move the horns 9, 9 to release the car and at the same time move the horns 10, 10 into position to engage the car wheels as the car moves forward under the action I of gravity.
sition shown in dotted lines in Fig. 1 and in full lines in Fig. 2. On account of the eccentric mounting of the sheaves 42, 42 the weights 46, 46 apply a gradually increasing resistance to the downward movement of the track section with the result that it is brought to rest in alinement with the track 2 with a minimum of shock. The weights 46, 46 are of such size that they will be lifted by the combined weight of the track section and of a car, but will lift-the track section back to normal position after the car has passed from it.
After the track section 4 has been released, as before described, and as it approaches alinement with the track 2, the chain 72 is tensioned and the brake band 68 is released from the wheel 67 and the horns 61 are permitted to be moved by the previously compressed spring 66 to give the wheels of the dumped car an impulse which serves to start the car over the hump of the pivoted track section and downward onto the return track 2.
As soon as the car has passed from the section 4 the section is at once raised to normal position by the weight 46, 46. On account of the eccentric mounting of the sheaves 42, 42 the weights supply a gradually decreasing lifting force which finally becomes practically equal to the weight of the section. As a result of this gradual decreasing lifting force the track section is elevated with a minimum of shock.
While the track section 4 is depressed the horns 9, 9 and 10, 10 are held in the position as last described by, the engagement of the rollers 59, 59 with the flanges 39, 39 of the gallows frame. The operator may, therefore, if desiredrelease his hold on the lever 20. As soon as the track section returns to its normal upper position the weight 32 is permitted to act to move the- horns 10, 10 to release the 'car and to move the horns 9, 9 back into car engaging position. It will be observed that the distance between the horns 9, 9 and the horns 10, 10 is somewhat less than the length of a car. As the result of this if a second car moves onto the dump while the first car is engaged by the horns 10, 10 it will be held. a slight distance back from the horns 9, 9. This gives time for the horns 9, 9 to be returned into operative position before the second carreaches them.
The car released from the horns 10,10
at once advances by gravity and engages the trip levers 54, 54 to depress them and to thereby throw the latches 47, 47 into position to engage and support the track sec tion 4. If, for any reason, the latches do not move, the shapes of the trip levers are such that the car will be stopped.
The advancing car moves first on to the upper slightly inclined part of the track section 4 and finally onto the part which is inclined sharply downward. As the car approaches the downward inclined part its wheels are engaged by the horns 61 and the downward movement of the car is first resisted, and then stopped by the combined actionof the spring 66 and the brake band 68 engaging the wheel 67. The car remains in this position until dumped, its end having been opened either manually or automatically, as before described.
After dumping, the operator by moving the lever 20 can release another car from the horns 9, 9, which will act to release the pivoted track section to-permit it to drop and the entire operation of the dump will then be repeated in the manner which has been before described.
It will be observed that the construction of the gallowsframe is such that when the frame and the pivoted track section are depressed the upper cross member 35 of the frame is in position to engage the bufier of a car. In this way an additional safety device is provided for preventing a car, which may in some manner have gotten past the horns, from running OK the open end of the track 1.
I am aware that it has been heretofore proposed to construct a car dump having superposed tracks and a shiftable track section arranged to aline successively with the two tracks. I do not, therefore, claim this combination as a part of my present invention. Neither do I claim broadly as part of my present invention pivotally mounted spring andbrake controlled horns for bringing a car to rest in dumping position on an inclined track. This feature is disclosed and claimed in a copending application by another inventor.
