Adler, Michigan Qity, ind, assignor to Fullman Incorporated, tihicago, ill., a corporation of Delaware Filed Jan. 29, 1963,5ier. No. 2%,759 13 Claims. (Qt. Elfi -33 7} The present invention relates to covered hopper vehicles and more particularly to a hatch cover arrangement employed in covered hopper cars.

Covered hopper vehicles generally include a plurality of lengthwise spaced hoppers, each having an individual discharge portion at the lower end thereof. Conventionally the tops of the cars are covered to protect the cargo being carried from the weather and the like and loading of the individual hoppers is accomplished by way of a hatch formed in the top. Heretofore, it has been commonly practiced to provide each of the hoppers with separate hatches and covers therefor. Such arrangements necessitated the removal of each of the covers for loading and required individual loading of the hoppers through the associated hatches.

To facilitate the loading, it has also been proposed to provide a single continuous hatch and cover therefor extending over each of the hoppers. In these continuous hatch arrangements the hatch covers have generally been pivotally attached along one side of the hatch for swing movement over and away from the hatch. Hatch covers of this general type have generally been of such weight that it requires two men to safely manipulate the same. Moreover, with the swinging type of the hatch in the open position thereof the underside is exposed and collects debris such as dirt and the like, which when the hatch is closed drops into the hoppers so as to tend to contaminate the cargo stored therein.

It is an object of the present invention to provide a covered hopper car hatch arrangement which obviates the dilficulties encountered heretofore.

It is a further object to provide a covered hopper car hatch arrangement which is of relatively simple construction and easy to handle.

It is still a further object to provide a new and improved roof for covering a plurality of hoppers in a hopper car wherein the roof incorporates a hatch arrangement including a hatch opening extending continuously over each of the hoppers, and a hatch cover means which is mounted for movement between a horizontal covering position over the hatch opening and a horizontal position over the roof to one side of the opening.

A more specific object is to provide an improved hopper car construction wherein a series of hopper type compartments are available for uninterruptedly loading the compartments by the provision of a continuous unitary hatch opening, and a hatch cover arrangement including operating means therefor for efficient movement of the cover into and out of hatch-opening sealing position.

Further objects and features will hereinafter appear.

FIG. 8 is a cross-sectional view taken substantially along line 8-8 of FIG. 7.

Referring now to the figures, the hatch arrangement MB of the present invention is shown embodied in a covered hopper car of more or less conventional construction, including side walls 12, end walls 13, and a roof 14. Disposed between the end walls 13 and the side walls 12 are hoppers ll of which the upper portions thereof are shown in FIG. 3. The lower or discharge portions (not shown) extend between the trucks and may be of any suitable design.

The hatch arrangement ll is formed in the roof 14 which extends between and is fixed to the side and end walls 12 and 13 in the usual manner and includes generally a hatch opening and a hatch cover 17 disposable thereover and movable as shown in FIGS. 2, 5 and 6 between the closed position shown in the full lines to a hatch open position shown in phantom. Movement of the hatch cover 17 between the open and closed positions shown is accomplished by means of operating mechanisms 18 which are constructed and arranged to displace the hatch cover 17 vertically into and out of a cover sealing engagement with the hatch opening 16 and when so displaced out of sealing engagement permit the cover to be shifted in a substantially horizontal plane to a position spaced from and clear of the hatch opening 16.

As shown the roof 14 includes side roof sheets 19 which are fixed along their outer edges to the side walls 12 and end roof sheets 21 which are fixed along their transverse edges to the end walls 13 and inside carlines 15 and along their side edges to the side walls 12. Suitable transverse reinforcing means or outside carlines which may be in the form of angles 22 are spaced lengthwise of the car and fixed to the outer surface of the roof sheets. Running boards 23 extending the length of the car are fixed to the transverse reinforcing angles 22 on opposite sides of the hatch opening. Additional running boards 24 are fixed to the roof end sections at each end of the hatch opening 16.

The hatch opening is defined along its longitudinal edges by

upright frame members

26 and 27 formed along the inner sides of the roof sheets E9. The

frame members

26 and 27 are each formed with an inwardly and upwardly inclined section 28 from the inner end of which there extends substantially

vertical sides

29 and 31 respectively. Curling outwardly from each of the vertical sides 29 and 3 are semi-cylindrical rims 32 on which the hatch cover 17 is adapted to rest in sealing engagement as more fully to be explained hereinafter. The vertical side 31 is of a lower height than the vertical side 29 to the extent required to accommodate the components of the hatch cover operating mechanism and permit lateral movement of the hatch cover 17 thereover.

The ends of the opening 16 are similarly defined by upright frame members 30 formed along the inboard ends of the end roof sheets 21. Each of the frame members 30 includes an upwardly and inwardly inclined wall 33, an upstanding end wall 34, and an outwardly curled semicylindrical rim, the rim being curled similarly to the rims 32 and inclined to accommodate the difference in height of the side

upright frame members

26 and 27.

Bracing and reinforcing the roof 14 at spaced intervals along the length of the hatch opening are reinforcing assemblies, as shown in particular in FIGS. 7 and 8. The reinforcing assemblies 37 each include a U-shaped welded to the adjacent sheets 42;.

. 3 top stilfener plate 38 extending transversely across the opening 16 and fixed at its ends to the associated roof

hatch frame members

26 and 27 by way of gussets 39 welded to the inclined portions 23.

The stiffener plate 38 is formed with a curved section so as to provide a smooth flowage surface over which the material flows during loading of the hoppers. Fixed to the underside of the upper stitfener plate 38 is a stiffener web 41 which extends between the side walls 12 and functions also as an inside carline. The stiffener web 41 is fixed to the side walls 12 at its ends and to the underside of the roof 14 along its upper edges.

Along the area in which the hatch opening overlies a hopper partitioning wall 4d as shown in FIG. 3, the partitioning wall 49 may be formed with a U-shaped cut-out to receive the upper stiffener plate 33 which is fixed as described above. The hopper partitioning wall 40 provides adequate reinforcement along the attachment to the car sides 12.

The hatch covers 17 may be formed from a plurality of end to end positional sheets 42 joined by strips 43 The cover 17 is formed along the side overlying the frame member 26 with a downwardly depending lip 44 which is adapted to extend over the end of the adjacent rim 32. Along the other side overlying the frame member 27 the cover 17 is formed with a downwardly depending flange 46 of a length such that when the horizontal web 47 projecting therefrom rests on the adjacent rim 32 as shown in FIG. 5, the cover 17 is maintained in a substantially horizontal position. Projecting downwardly from the horizontal web 4'? is the lip 44. A similar lip 54 is formed along the ends of the hatch cover 17 depending from the inclined horizontal web 48 extending from a vertical flange 49. Suitably fixed to the underside of the cover 17 along the areas contacting the rim 32 is a sealing gasket 51 formed from rubber or the like.

The hatch cover operating means 18 for lifting and moving the hatch cover 1'7 includes generally a plurality of hand wheel assemblies 52 associated with pivot assem blies 50.

The hand wheel assemblies 52 each include a hand wheel axle 53 to the upper end of which there is fixed a hand wheel 54. At its lower end the axle is threaded and turnably supported in a pivot arm 55 of the cover pivoting assembly 50. Overlying an opening 6! in the hatch cover 17 and fixed thereto is an axle bearing '6 having an opening 57 accommodating the axle 53. An axle washer 58 is fixed to the axle 53 and underlies the axle bearing 56. A stop washer 59 is fixed to the lower end of the axle 53 to prevent detachment of the latter from the pivot arm 55.

The hatch cover pivot means 50 includes the pivot arm 55 which threadably receives at one end the axle 53. At its other end the pivot arm 55 is fixed to a pivot stud 61 journaled in a pivot bracket 62 which is fixed to the upright flange 31 of the frame member and the stilfener plate 38 by means of attachment plates 63. Fixed to pivot stud 61 is a bearing 64 and between the underside of the bearing 64 and the top of the pivot bracket 62 is a pivotally mounted thrust bearing 66.

For limiting turning movement of the pivot stud 61 and thereby the pivot arm 55 a stop lug 67 is fixed thereon which coacts with a stop lug 68 fixed to the bearing housing 62. The housing stop lug 68 and pivot stop lug 67 are located so that the hatch cover 17 is freely angularly movable about 100 to the position shown in phantom lines and designated as O in which position the hatch cover 17 clears the opening 16. Also the bearing housing stop lug 68 is located to abut the pivot arm 55 when the hatch cover 17 is disposed in alignment with the hatch opening 16.

In operation assuming that the hatch cover 17 is in its closed position wherein the components of each of the hatch cover operating assemblies 18 are in the position shown in FIG. 5, a seal '71 tied about one of the hand wheels 54 and a strap 72 fixed to the hatch cover 17 is broken. In order to provide free access through the hatch opening 16 the handle 54 of each the handle wheel assemblies 51 is turned so that screw end of the axle 53 threaded in the pivot arm 55 moves upwardly. The hatch cover 17 fixed to each of the axles by means of the hearing collar 56 disposed between the washer 5S and the hand wheel 54 is accordingly raised. The hand wheels are turned until the hatch cover assumes the position designated U as shown in phantom in FIG. 5.

In the raised position U the lip 44 is clear of the rim 32 on the side frame member 26 so that the cover 17 is free to be shifted laterally over and clear of the opening. This is accomplished by pushing against a hand.

wheel 54 in the direction of pivoting movement A of the pivot arm 55 as shown in PEG. 4. The pivot arms 55 associated with the other assemblies 13 also simultaneously pivot or swing in the same direction and form in the nature of a parallelogram linkage so that the hatch cover 17 is displaced in a substantially horizontal plane. Shifting movement of the hatch cover 17 is terminated by engagement of the stop lugs 67 and 68 and assumes the open position 0 as shown in FIG. 5.

To close the hatch cover 17 the procedure is reversed; the hatch cover being pivoted in the direction B until arm 55 comes into contact with stop lug 68 in which position the hatch cover 17 is aligned with the hatch opening 16 as shown in the phantom line position designed U. Thereafter the hand wheels 54 are turned to lower the hatch cover 17 and the latter is tightly clamped on the rims 3:2.
