  • a supporting lever In order to open the roof, a supporting lever is pivoted by operation of a hand lever on the top of the container or car.
  • This supporting lever carries, at its lower end, a supporting roller bearing on the cross-connection and, when operated, lifts a roof section which can then be pushed over the other closed roof section.
  • the two identical roof sections In the closed condition of the roof, the two identical roof sections have their adjacent inner ends at least partially overlying the crossconnection.
  • the roof sections run on rollers, arranged in pairs with one pair at the end of a roof section nearest the cross-connection and the other pair at the end of the roof section nearest the associated end wall.
  • the first mentioned pair of rollers run a short distance on the cross-connection and then on tracks on the other roof section.
  • the last-mentioned rollers run on tracks on the upper edges of the side walls, and these latter tracks have inclinations or ramps in the proximity of the associated end wall to provide a lifting movment at this end of the roof section when the roof section is moved toward the open position.
  • This known type of openable roof which must form a walkway since it is opened from the top, is made oflight metal. If a roof having the same strength is to be constructed of far less expensive steel, it will have about twice the weight of a light metal roof but its costs will be only about one third those of the light metal roof. If such a steel roof is so designed that it can be opened from the bottom or from a level beneath the roof, its weight can be greatly reduced because it need not serve as a walkway.
  • roller tracks terminate at their ends, that is, in the position of the supporting rollers of a roof section in its end or closed position, in inclined surfaces or ramps on which the rollers roll up and down during longitudinal displacement of the roof section so that the moving roof section is thus lifted or lowered.
  • This invention relates to means for opening and closing roofs of freight cars and other containers and, more particularly, to a novel and improved apparatus for opening and closing sectional roofs of railroad freight cars and other contamers.
  • the roof operating apparatus of the invention includes a first cable section having one end secured on that end of a roof section nearer the end wall of the freight car or container, withthe other end of the cable section being secured on a cable drum between the side walls of the freight car intermediate the ends thereof.
  • the cable drum is mounted for rotation about a horizontal axis which is perpendicular to the longitudinal center line of the car or container.
  • a second cable section has one end secured to this drum and its other end secured on or adjacent that end of the roof section nearer the center of the car, By rotating the cable drum, with resultant winding of one cable section and unwinding of the other cable section, the sliding roof section is moved horizontally parallel to the longitudinal center line of the car or container.
  • the cable drum is rotated through the medium of a hand crank to which it is connected by suitable transmission means including shafts, chains and gears, with the interposition of a reduction gearing of the required ratio.
  • suitable transmission means including shafts, chains and gears, with the interposition of a reduction gearing of the required ratio.
  • Means are provided whereby, with a single hand crank or with either one of a pair of hand cranks, one on either side of the car or container, either of the two roof sections of a two-section sliding roof can be opened or closed at will.
  • An object of the present invention is to provide improved and simplified apparatus for opening and closing a sectional roof of a freight car or other container.
  • Another object of the invention is to provide such an apparatus in which any selected section of a sectional roof can be opened or closed at will from a certain location on a freight car or other container and without the operator having to climb on the container or freight car or to leave a single operating location.
  • a further object of the invention is to provide such an apparatus including a rotatable cable drum and cable sections extending between the drum and the opposite ends of the roof section.
  • another object of the invention is to provide such an apparatus in which the cable drum for a roof section is rotatably mounted on a cross-connection between the side walls of the car or container intermediate the end walls thereof, for rotation about a horizontal axis which is perpendicular to the longitudinal center line of the car or other container.
  • a further object of the invention is to provide such an apparatus in which the cable drum is rotated by a handcrank to which it is connected by suitable transmission means.
  • Still another object of the invention is to provide such an apparatus for use with a two-section roof and in which a respective drum is provided for each roof section, with a single handcrank or either one of a pair of handcranks being selectively operable to operate either one of the two drums and without the operator having to leave a single operating location.
  • a further object of the invention is to provide such an apparatus including cooperating means on the cable drum and the associated roof section for lifting the inner end of the associated roof section in advance of its opening movement and for locking the inner end of the associated roof section responsive to its attaining its closed position.
  • An ancillary object of the invention is to provide such a sectional roof operating apparatus which is simple, economical, efficient, and operationally safe.
  • FIG. 1 is a side elevational view of a covered freight car having a two-section openable roof, with the roof shown partially opened;
  • FIG. 2 is a top plan view of the two-section roof, with the roof shown in the closed condition;

  • the invention is illustrated as applied to a covered freight car F having end walls E, E, side walls S,S, a floor or base B and a two-part sectional roof generally indicated at R.
  • the roof R comprises two roof sections 1 each movable longitudinally of car F between a closed position and an opened position. In the opened position of the roof R, one roof section 1 overlies the other roof section I and, in the closed position of the roof R, the inner ends of the roof sections 1 at least partially overlie a cross-connection 7 extending between side walls S intermediate end walls E.
  • Each roof section 1 includes. adjacent its outer end or the end thereof adjacent the associated end wall E in the closed position of the roof section, a transverse rod or partition 2 having one end of a spring 3 secured thereto.
  • the opposite end of each spring 3 is secured to one end of a cable or cable section 4 which is guided over a guide roller 6 rotatably mounted on an end cross rod or partition 5 and has its other end secured on a cable drum 9 mounted on cross-connection 7 for rotation about a horizontal axle 8 which is perpendicular to the longitudinal center line of car F.
  • Another cable section 10, which may be part of a single cable including the cable section 4 has one end secured on cable drum 9 and is partly wound on the cable drum.
  • the cable 10 is guided over a guide roller 12 rotatably mounted on another cross rod 11 adjacent the inner end of the associated roof section 1, which is the end overlying the cross-connection 7 when roof R is closed.
  • the end of cable section 10 is secured to one end of the spring 13 whose opposite end is secured to a cross member or rod 14 of the associated roof section.
  • cable drums 9 rotatably mounted on crossconnection 7, one operatively associated with each roof section 1 and the respective cable sections 4 and 10 connected to the associated roof section.
  • Either cable drum 9 may be rotated by a handcrank or hand wheel 16 rotatably mounted at a fixed location on car F, such as at the center of car F in a position easily accessible from the ground as best shown in FIG. 1.
  • Each handcrank or hand wheel 16 has fixed thereto, to rotate coaxially therewith, a respective sprocket 22, connected by an endless chain 24 to a respective sprocket 21 coaxial with a clutch 25 operated by a clutch handle 26.
  • Clutch handle 26, and the clutches 25, may be operated conjointly from either side of the car.
  • Sprockets 21 are rotatable about an axis beneath floor or base B and which is also the axis ofa rotatable coupling shaft or rod 27 extending beneath floor B.
  • clutch handle 26 By selective operation of clutch handle 26 to control clutch 25, sprocket 21, adjacent the righthand side of the car as viewed in FIG. 3, may be coupled either directly to a sprocket 20 or, through coupling rod or shaft 27, to a sprocket 20a on the lefthand side of the car F as viewed in FIG. 3.
  • the sprocket 21 on the lefthand side of the car may be connected either directly to sprocket 20a or, through coupling rod or shaft 27, to sprocket 20, again through selective operation ofclutch 25 through clutch handle 26.
  • Respective endless chains 23 and 230 are trained around the sprockets 20 and 200 at their lower ends and around sprockets 19 at their upper ends.
  • Each sprocket 19 is connected through universal couplings 18 and a shaft 17 to rotate a respective drum 9, and suitable reduction gearing may be provided if necessary or desirable in the drives for the drums 9v
  • either roof section 1 can be opened or closed from either longer side S of car F.
  • roof sections I In the closed condition of roof R, roof sections I extend in the same plane or at the same level, so that the roof section 1 to be opened must first be lifted a certain amount.
  • lifting is effected by cams 28 arranged in circumferentially spaced relation at one end of each cable drum 9. These cams are engageable with respective finger bars or plates 29 each secured on the inner side of a respective roof section 1.
  • cams 28 engage beneath the associated finger bar 29 and lift the connected roof section 1 through a distance sufficient for the roof section to move over an inclined surface member 30 on cross-connection l and to the level of rails 31 extending along both sides of the other roof section.
  • Such lifting movement is made possible by virtue of the springs 3 connecting each cable section 4 of the associated cross member 2, since no horizontal movement of a roof section 1 is possible until the roof section has been lifted.
  • the end of the roof section 1 nearest the associated end wall E of car F is also lifted, during longitudinal movement of the roof section, by an inclined surface or ramp 32 and through the necessary distance.
