Definitions

  • This invention relates generally to the unloading of hoppers and is of particular utility, and will be described herein, as applied to the unloading of railroadhopper cars such as are commonly used to transport coal, ore and similar materials.
  • railroadhopper cars such as are commonly used to transport coal, ore and similar materials.
  • Such cars are equipped with sloping bottoms and closure gates underneath, the gates being opened to permit the gravity discharge of the contents of the car. Notwithstanding the sloping bottoms, the material to be discharged, whether it be coal. ore or other similar material, does not flow freely and continuously but tends to bridge over the discharge openings from time to time, requiring much manual labor to free it and empty the car. The same difliculty is experienced in the emptying of hoppers generally. In the case of railroad cars, frequently as many as six laborers may be employed in the unloading of a single car, and even with such manual asrequiring more than a fraction of the man-power heretofore used for the purpose.'
  • Fig. 1 is a diagrammatic, side elevational view of a typical railroad hopper car having the preferred embodiment of the apparatus applied to it;
  • Fig. 2 is a broken out, side elevational view of the apparatus illustrated in Fig. 1 but much en- ,larged;
  • Fig. 3 is a plan view of the apparatus
  • Fig 4 is an end elevational view of the apparatus (the terms "side" and end being used in the same sense as applied to the car itself) and Fig. 5 is an enlarged view of a detail.
  • a heavy mass is appropriately supported in a position to be vibrated, i. e. more or :less vertically reciprocated, into and out of contact with the tops of opposite walls of the hopper or car.
  • a suitable mechanism by which the structure can be placed in position.
  • thema'ss is in the form of a frame structure dimensioned to bridge and seat upon the car side walls; and a hoist may be used to lower the frame into position on the car and raised ofi the car when the latter has been emptied.
  • the structure seats loosely on the tops of the our walls and is arranged to be vibrated with such force as to cause it to rise and fall, out of and into contact with the tops of the car walls, so as to subject both of the latter to continuous and severe jarring or hammering, the mass of the frame structure being such as to cause the car itself to vibrate bodily.
  • the general bodily vibration of the car is in a vertical direction, it has also been found that by means of such an arrangement as that illustrated, the car walls are caused to flutter or vibrate toward and from each other.
  • the material in the car discharges in a virtually continuous flow and in a remarkably short time without any manual assistance whatsoever.
  • the time. required is of the order of five minutes, as contrasted with the half hour mentioned above.
  • a. conventional hopper car marked i, is shown in Fig. 1, with the apparatus 2 applied to it in a generally central location longitudinall of the car and seated on the tops of the side walls 3. While not shown in detail, the car is equipped with the usual gates 4, which are capable of being opened to discharge the load through the bottom of the car.
  • this preferred form of the apparatus consists of a main frame 5 and an auxiliary frame 6 mounted on it, both frames being of generally rectangular form.
  • the main frame consists of side portions 1, 8 united by a heavy bridge structure 9 including end plates it.
  • a heavy bridge structure 9 including end plates it.
  • the details of these elements are immaterial so far as the invention is concerned, it being important only that the frame be extremely rugged and of adequate mass for the purpose.
  • a centrally located shaft H which carries eccentric weights l2, such shaft and weights constituting 3 that this preferred method of reciprocating the frame, i. e. by means of rotating eccentric weights, will tend to impart a compound motion to the frame.
  • the vertical component of such motion is of prime importance so far as the present invention is concerned but the horizontal or lateral components also contribute, and are availed of to good advantage when the compound motion is eflective, as in this instance, in a plane transverse to the length of the car. With the structure so arranged, the vibration of the car walls is accentuated.
  • channel members i3, H Extending along and beneath the side portions I, of the main frame are channel members i3, H the depending flanges of which straddle the tops of the car walls.
  • the channel members are loosely connected to the main frame, that is, with freedom for limited vertical movement relatively thereto, the connection of channel i3 in Fig. 2 being shown as consisting of bolt i 5 passing through elongated hole IS in the frame side portions.
  • Secured to the underside of the side frame members I, 8 are spaced shoes H on which the whole structure is supported on the channel members. The latter thus serve not only to guide or locate the frame on the car walls and restrain it against undue lateral movement but also to receive the direct pounding of the vibrated mass.
  • the auxiliary frame 6 is supported on the main frame by a series of springs l8 and On it is mounted a motor i9 connected, as by belt 20, with shaft Ii.
  • a motor i9 connected, as by belt 20, with shaft Ii.
  • the auxiliary frame may be suitably restrained against undue horizontal movement relative to the main frame, as by such means as the bolt and spring connections 2
  • passes through a bracket 23 secured to main frame I, the compression of spring 22 against bracket 23 being adjusted by 1001: nuts, as illustrated.
  • the opposite side of the auxiliary frame may be similarly tied to the main frame, as illustrated in dotted outline at the right of Fig. 4.
  • such bolt and spring connections may be utilized to apply appropriate tension to the belt 20.
  • Means may also be provided for braking excessive vertical movement of the auxiliary frame relative to the main frame.
  • One form of such means is shown in detail in Fig. 5. It consists of a pair of vertical plates 25, 26 secured to and upstanding from the main frame and a sleeve 21 secured to and depending from the auxiliary frame. Within sleeve 21, but having no connection with it, are two shoes 28, 29 which are thrust apart and held in frictional engagement with plates 25, 26 by spring 30. The clearance between shoes 28, 29
