jib/ 1 United States Patent 3,097,612 OUTLET STRUCTURE FOR RAILWAY HOPPER CARS George B. Dorey, Westmount, Quebec, Canada, assignor to Enterprise Railway Equipment Company, Chicago,

111., a corporation of Illinois Filed Nov. 6, 1959, Ser. No. 851,459 7 Claims. (Cl. 105-282) This invention relates to an improved outlet structure for a load containing hopper of the type employed in connection with railway hopper cars and the like for conveying finely comminuted lading.

The objects of the invention, among others, are: To provide improved sealing means around the edges of a sliding gate; to provide housing means for retaining gaskets in sealing position; to provide coordinating wedging means between a movable gate and hopper structure; and to provide a sealing gasket strip around the edges of a movable gate with provision for disposing the end portions of said sealing gasket strip in overlapping relation and thereby effect a double seal to coact with the projecting end of a sliding gate.

The invention further resides in certain details of construction and refinement of parts associated with the improved structure.

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 drawingslce structure 19. The framing structure 19 is formed in part by inner and outer longitudinally extending

frame members

20 and 21 which are transversely united by

frame cross members

22, 23 and 24.

The longitudinally extending

frame members

20 and 21 include

upper portions

25 and 26 which respectively over- FIG. 1 is a vertical transverse elevational view of the taken through the hopper on a line 44 of FIG. 1 and showing by conventional dot and dash lines the position of the parts with the gate in opened position.

FIG. 5 is a vertical sectional view taken on a line 5-5 of FIG. 2.

FIG. 6 is a fractional vertical sectional view on an enlarged scale taken on a line 6-6 of FIG. 3.

FIG. 7 is a fractional vertical sectional view on an enlarged scale taken on a line 77 of FIG. 3.

FIG. 8 is a fractional vertical sectional view on an enlarged scale as taken on a line 8-8 of FIG. 3.

FIG. 9 is a fractional vertical sectional view on an enlarged scale taken on a line 99 of FIG. 3.

FIG. 10 is a perspective sectional view of the gate.

In said drawings wherein the improvement is shown as applied to a railway hopper car, the car structure is indicated by a center sill 10 and side wall 11 having an edge angle 11a and interposed between said center sill and side wall is a four-sided hopper 12 having a discharge opening 13. In practice there are actually hoppers disposed on opposite sides of the center sill 10 in transversely aligned relation but inasmuch as the construction of the various hoppers is similar, the description herein will be confined to only one of such hoppers.

Each hopper 12 is formed in part by inner and

outer side walls

14 and 15 which meet with oppositely sloping

walls

16 and 17 to complete the four sides of a foursided hopper. The marginal edges of the

said walls

14, 15, 16 and 17 are spaced apart to form the discharge opening 13. The discharge opening 13 is closed by a sliding gate 18 which in turn is supported by a framing lie the inner and

outer walls

14 and 15 and the cross member 22 likewise includes an upper portion 27 which overlies the sloping end wall 16. The

cross members

23 and 24 are disposed at the end of the discharge opening 13 opposite to cross member 22 with cross member 23 disposed above the gate 18 to overlie sloping wall 17 of the hopper. The cross member 24 includes a vertical wall section 24 disposed below the gate 18 and flanged at its upper margin at 24" to underlie the gate 18. The flange 24 is spaced from the lower marginal edge 23' of the upper end wall 23 to define a slotted opening 28 through which the gate 18 slidably extends. The inner longitudinally extending frame member 20 preferably extends I vertically above the gate 18 for attachment at 29 to the inner hopper side wall 14.

Horizontally disposed ledges 30, 31 and 32 of

frame members

20, 21 and 22 form supports for the gate 18 in closed position and the said

longitudinal frame members

20 and 21 are extended well beyond the slotted opening 28 at 33 and 34 to provide continuity of

ledges

30 and 31 for supporting the gate 18 in opened position.

The gate 18 is beveled slightly, FIG. 10, as indicated at 35 to the extent shown at 35a at the leading end 36. Longitudinally extending flanges 3737 are provided at and secured to the sides of the gate 18 and they have their upper marginal edge surfaces 38 inclining down- Wardly from the trailing end 39 to the leading end 36 of the gate 18 to provide wedge shaped side flanges presenting the upper edge surfaces 38 inclined relatively to the gate bearing surfaces of

ledges

30 and 31 of the

rail members

20 and 21.

The trailing end portion 39 of the gate'18, which normally projects beyond the slot 28, is inclined on the underside to provide an end portion 41 inclined upwardly as indicated at 41a (FIG. 10) to extend in the direction of or parallel to the inclined surfaces 38. Secured to the upper surface of the end portion 39 is a reinforcing bar 42 which extends transversely of the gate 18 and is of such thickness as to dispose its upper surface 43- in alignment with and forming continuations of the edge surfaces 38 of the side flanges 3737 and the beveled surface 35 at the leading end 36 of the gate 18. The said surfaces 35 and 38-38 in combination with surface 43 lie in a continuous common plane inclined relatively to the top surface of the gate.18 around its upper margins. Coacting with this marginal surface is a resilient gasket 44. The gasket 44 is preferably of hollow circular section and readily deformable to seat in receptacles as will be de scribed.

Tlhe gasket 44 extends around the four sides of the discharge opening 13 and is of single ply on three sides of the opening as indicated at 45, 46 and 47 and on the fourth side provides for a two ply overlapping construction by having the two

ends

48 and 49 overlap for substantially the entire width of the [gate 18 (FIG. 3).

For holding the gasket 44 in place there are provided housings on three sides in the form of

inclined shedding plates

50, 51 and 52 which receive the

sections

45, 46 and 47. On the fourth side of the opening at the projecting or trailing end 39 .of the gate 18 there is provided an angle shaped reinforcing member 53 having one wall 54 underlying the upper transverse wall 23 and the other Wall 55 outstanding therefrom. The two ends of the

gaskets

48 and 49 are positioned in the angle formed by the walls 54 and 55 and held therein in a deformed state by

lugs

56 and 57 which are welded in place on the respective walls 54 and 55 to form restricted mouth openings therebetween.

Similarly the

other gasket sections

45, 46 and 47 are held in place by lugs 58 for section 45', at 60 for section 46 and at 62 for section 47.

The gate 18 is preferably operated by toggle mechanism, generally indicated at 64, and which preferably consists of a rotatable shaft 65 mounted in bearings 66 at the outer ends of

extensions

33 and 34. The toggle mechanism 64 includes arms 6767 non-rotatably mounted on the shaft 65 and links 6868 respectively pivoted at one end to the said arms at 69 and having their opposite ends pivotally connected to the gate 18 by pivots 70 which extend through lugs 71 secured to the trailing end 39.

The arms 66, in combination with their associated links 67, as shown by full lines in FIG. 4, assume a slightly over-center knuckled position thereby providing a toggle lock to force the gate 18 to tightly closed position against the resilience of the gasket 44.

The shaft 65 is rotated by a suitable operating head 72 having a series of openings 73 for the accommodation of a removable bar conventionally indicated at 74.
