1N VEN TOR. zi/George 5 areg, Mm? www United States Patent 3 082,705 SLIDING HOPPER DISHARGE OUTLET CLOSURE ACTUATING MECHANISM George B. Dorey, Westmount, Quebec, Canada, assigner to Enterprise Railway Equipment Company, Chicago,
Ill., a corporation of Illinois Filed Apr. 9, 1959, Ser. No. 805,266 Claims. (Cl. 10S-282) The invention relates -to an improved hopper discharge outlet structure of the type employing a sliding gate for closing la discharge opening and is of particular importance in connection with the discharge `opening of railway hopper cars and the like.
The objects yof the invention, among others, are to provide improved rotatable arm and associated linkage mechanism for moving a sliding gate including stop means for limiting rotation of the arm means; to provide stop means for limiting movement of a sliding gate in relation to linkage; to provide for connecting axially spaced operating hubs with connecting means therebetween; to provide irnproved retaining and sealing means for a rotatable operating shaft; and to make provision for raising a sliding gate in open position above a slotted opening through which said gate extends and thereby provide cleaning accessibility to the interior of the hopper.
The invention further resides in certain details of construction -associated with the framing and in the manner in which the gate and mechanism are related to each other `and to the hopper structure. Y
For further comprehension of the invention, reference may be had to the accompanying drawings wherein the improvement is shown as applied to a railway hopper car.
In said drawings,
FIGURE 1 is a vertical transverse sectional view taken through the lower part of a hopper car and showing approximately one half the width of the car.
FIGURE 2 is a vertical side elevational view of the structure shown in FIGURE 1 as seen from left to right.
FIGURE 3 is a plan view of FIGURE 2 lwith the floor sheets, sloping iloors and car structure eliminated to better illustrate the structure.
FIGURE 4 is a longitudinal vertical sectional view taken on a line 4-4 of FIGURE l and showing in con- `ventional dot and dash lines the position `of the parts with the gate in open position.
FIGURE 5 is a longitudinal vertical sectional view vsimilar to FIGURE 4 except that the gate is shown in elevated and fully withdrawn position to provide `cleaning access to the interior of the hopper through the slotted end of the frame.
FIGURE 6 is a transverse sectional view through the outlet assembly as seen on a line 6 6 of FIGURE 2,
FIGURE 7 is a plan view of theA gate and mechanism assembly as seen in detached relation.
FIGURE 8 is a side elevational view of FIGURE 7.
FIGURE 9 is a fractional vertical sectional view on an enlarged scale as taken on a line 9--9 of FIGURE l3.
FIGURE l() is a vertical elevational end view of the lstructure shown in FIGURE 9 as viewed from left to right.
ln said drawings the car structure is indicated by a 3,882,705 Patented Mar. 26, 1963 cludes inner and `outer longitudinally extending side members 20 and 21 which are united with transversely extending members 22, 23 and 24, the members 23 and 24 being separated by an intervening space to deiine a slot 25 through which the gate 1S extends. The side members 20 and 21 are formed of sheet metal plates and have outwardly hanged lower margins as indicated at 26 and 27 respectively and include vertically extending sections 28 and 29 between which the gate 1S slides and is guided.
The upper part of wall 29 is anged outwardly at an incline as at 30 to underlie the outer side wall 14 of the hopper and the upper part of wall 23 overlies 4the inner side wall of the hopper. The transversely extending end wall 22 is likewise flanged outwardly at its lower margin to present an outwardly extending ilange 31 and is also flanged outwardly and upwardly to overlie the sloping floor 15.
The upper transversely extending wall 23 extends between the upper portion of members 28 and 30 and is welded thereto as indicated at 32 and 33 and the lower tr-ansversely extending wall 24 is of generally Z shape including a web portion 34 and upper and lower anges indicated at 35 and 36 respectively. The upper llange 35 underlies the gate and the lower flange 36 extends below the level of the lower flanges 26 and 27 a suicient distance to admit the entrance of a ange of removable chute as will hereinafter be described.
There are provided ledges on three sides of the opening as indicated at 37, 38 and .39 which in combination with upper flange 35 provide a four-sided continuous support for the gate in closed position. The ledges 37 and 38 are respectively carried by vertical portions of the side members 20 and 21 and the ledge 39 is carried by the transversely extending wall 22. The side ledges 37 and 38 slope downwardly to bias the gate towards closed position and said ledges extend well beyond the slot 25 and join with iianges 40 and 48a which extend laterally inwardly from the side members 20 and 21 respectively. Internal ilanges 28 and 29 on the vertical sections 28 Vand 29 provide supporting surfaces as extensions of the 'to and forming continuations of ledges 37 and 38 and thus the sliding gate slides from closed to open position along continuously extending sloping runways. The end ledge 39 is beveled at 39a to ease the gate to its closing position and compensate for any unevenness or sagging of the leading edge of the said gate.
The upper transverse member 23 is reinforced on its under side by an angle shaped member 41 having one flange underlying the member 23 and the other ange 42 lying normal thereto. The trailing end of the gate is flanged upwardly at 43 and secured thereto are lugs 44 which are apertured for receiving a pivot 45 for making connection with operating mechanism, as will be described.
The operating mechanism includes -a rotatable shaft 46 which is journaled in bearings 47 that are located at each sidebf the framing and preferably consisting of short lengths of tubes welded `as at 48 to the side framing members and at 49* to an angle tie member Sil which extends transversely between the side framing members and welded thereto at 51 and 52. Arms 53 are non-rotatably mounted `on the shaft 46 and pivotally connecting said arms and the lugs 44 are pairs of links 54--54. The outer end of each arm is apertured at 55 to receive pivots 56 for the purpose of making connection with one end of the linkage formed by arms 54. The linkage which consists of the pair of links 54 straddles the arms 53 and the lugs 44 and pivotally unites with -said respective members by means of the pivots 45 and 56. The pivots 45 and 56 preferably consist of headless pins held in place on the links by welding as at 57 to provide an integrated link assembly at each arm.
The shaft 46 is preferably of non-circular shape and at its inner end is fitted with a ilanged circular bushing 53 held in -axial relation on the shaft by a headless pin 59 and at the opposite end there is provided an operating head 6d having a hub portion 6i of circular shape forming a bearing for the shaft. The arms 53 are provided with hublike portions 62-62 each having a non-circular opening 62', FIG. 8, for receiving the correspondingly shaped shaft 46 to provide for non-rotatable mounting thereon. The hublike portions 62-62 are spaced axially from each other by a hollow tubular spacer 63 and said spacer is united with the hubs of the arms by welding as at 64.
The pair of arms when integrally connected with the spacer 63 by means of welding function as a unitary member and the assembly as composed by the arms and spacer 63 is held in axial alignment on the shaft between the bushing '58 and the hub portion 61 of the head 60.
The arm and linkage when in extended position as seen in FIGURES 2 and 4 operate as struts between the shaft and gate to maintain the gate in closed position and when in extended position the arms rest on the tie member 50 with the axis 65 of pivot pin 56 lying slightly below and beyond a straight line joining the axis 46a of the shaft 46` with the axis 66 of pivot 45.
Each arm 53 is provided with a stop lug 67 adapted to engage with the tie member 50 to limit rotation of the shaft and thereby limit the extent of opening movement possible by rotation of the shaftA While the opening movement of the gate is thus limited when operable by means of the shaft rotation, provision is made for moving the gate beyond and above the slot in order to provide access to the ledges for cleaning purposes. The arrangement for this supplementary movement of the gate is effected through a provision allowing for a limited upward and outward movement of the trailing edge of the gate and to this end the linkage 54 is swingable about the pivot 56 to the position shown in FIGURE 5. The extent of supplementary movement so provided is limited by stop means 68 which engage with the linkage 54 and thereby limit the extent of swinging movement of the linkage. Each stop means 68 preferably consists of a plate member 69 welded at 70 to the related lugs 44 and having ends 71 projecting beyond the sides of the lugs to seat against the edge surfaces 72 of the linkage.
The operating head 60 lwhich is provided with a plurality of socket portions 73 for accommodating a removable bar (not shown), is also provided with a bracket portion 74 having a wall 75 spaced appreciably from the axis of rotation of the shaft and apertured at 76 to accommodate therethrough a key-shaped portion 77 of a sealing pin 78. The sealing pin 78 includes at one end a handle portion 79 and at its opposite end is formed with a section 80 of circular shape which is adapted to seat in an opening S1 formed in the head. The wall 75 is united with the body of the operating head by means of upper and lower Walls y82 and S3 which each include apertures 84 for receiving a sealing ribbon. The keyshaped portion 77 of the sealing pin is also apertured at 85 to align with the walls 32 and 83 when the sealing pin is in locking position thereby allowing for insertion of the sealing ribbon through aperture S4 in either of the lwalls S2 or 83 and through the aperture S5 of the sealing pin.
The sealing pin is mounted for axial movement in bracket plates 86-86 and outward movement of the pin is limited by a stop plate S7.
Shields in the form of inclined shedding plates 88 and 89 extend along the longitudinal side edges of the gate and serve to maintain the gate against upward movement and also operate as sealing means to guard against leakage. The said plates 8S and 89 terminate short of the lend of the opening to provide escapement passages to allow flow of lading and prevent packing of lading in the corners of the opening adjacent the leading end of the gate when the latter moves to closed position.
A groove 90 is provided along the inner longitudinal side edge of the frame for receiving one side of the frame of a removable extension chute indicated conventionally at 91. The groove is preferably formed by two plates 92 and 93 welded together and to the outstanding lower marginal flange of the inner frame member at 94. The plate 93 is disposed in alignment with the lower ange 36 of the `transverse member 24 and this provides for a groove opening on two adjacent sides of the frame as seen in FIGURE 5.
Assuming the gate is in closed position, the opening operation is effected by first withdrawing the sealing bolt and thereafter imparting a partial rotation of the shaft in -a clockwise direction as viewed in FIGURE 2 until the stop lugs abut the tie member when the gate then reaches the maximum `open position possible by rotation of the shaft. Should further opening of the gate be indicated, as sometimes necessary for cleaning purposes, the gate is moved bodily with the trailing end moving upwardly with the linkage swinging about the pivotal axis with the arms as seen in FGURE 5 and the underside of the gate 18 spaced, as by a block 95, above the surface of the flange 28. With the insertion of a block 95 between the gate 18 and each flange 28 'and 29 the entire gate is raised above the level of the slot and it is then possible to gain access to the runways for cleaning the same of any residue of lading resting thereon.
This accessibility for cleaning purposes is of special importance when transferring a car from one type of service to another as it is necessary that complete cleaning of the car be effected to avoid contamination of the lading.
Even though the gate be completely withdrawn to its fully extending portion including the supplementary travel provided by the swinging movement of the linkage, the closing is effected in one continuous operation by rotation of the shaft in an anticlockwise direction.
