Definitions

  • the present invention relates to railway cars or wagons provided with an openable roof device and more especially to open railway cars, i.e. cars of the kind in which the floor is bordered by two longitudinal walls connecting between them the end walls, the assembly constituting an open-topped body.
  • a primary object of the invention is to provide an openable roof device for a car which is water-tight and rain-proof and give a good protection for the goods housed in the car when the latter is stored in the open in bad weather.
  • a further object of the invention is to provide a rain-proof openable roof device for a car which can be rolled up from one of the ends of the car.
  • Another object of the invention is to provide a rainproof openable roof device for a car having a structure permitting an easy flow of the rain water outside of the car.
  • Another object of the invention is to provide an openable roof device for a car having a mechanical strength high enough for permitting several attendants to travel upon, and which is rain-proof and made of jointed elements transversely disposed and adapted to be rolled up on a winding drum located at one longitudinal end of the car.
  • Another object of the invention is to provide an openable roof device for a car made of jointed element which is brought to its closed position by a pull exerted on the leading element, the other elements being drawn in turn by the successive elements lying ahead.
  • Another object of the invention is to provide an openable roof device for a car made of jointed elements capable of being rolled up about a winding drum, which is brought to its closed position by a pull exerted on the leading element, and is drawn back to its opened position by a pull exerted on the trailing element.
  • Still another object of the invention is to provide an openable roof device for a car which is rain-proof and which may be brought to its opened and closed positions through positive controls.
  • Another object of the invention is to provide an openable roof device which is automatically and positively locked in its closed position.

  • FIGURE 1 is a partly sectioned elevation of a first form of waggon comprising an openable roof in accordance with the invention
  • FIGURE 2 is a section taken along the line II-II of FIGURE 1,
  • FIGURE 3 is a longitudinal section view, on an enlarged scale, showing details of the screens of the waggon of FIGURE 1.
  • FIGURE 4 is a partly sectioned elevation of a second form of Waggon comprising an openable roof in accordance with the invention
  • FIGURE 5 is a schematic perspective view of the various control and locking means for one screen of the Waggon of FIGURE 4.
  • FIGURES 6 and 7 are sections, on an enlarged scale, taken along the lines VIVI and V-IIVII, respectively, of FIGURE 5, and
  • FIGURE 8 is a schematic perspective view of an end of the Waggon of FIGURE 4.
  • the openable roof is formed in two parts A and B each constituting a movable screen.
  • brackets 4a, 411 for supporting drums 5a, 5b.
  • -On these drums are fixed the ends 6a, 6b of the screens A and B, respectively, which screens rest, by their lower faces, on the flanges of the channels 2a, 2b (FIGURE 2).
  • the supporting drums 5a, 5b are provided in a usual manner with return devices tending to make the drums rotate in the direction of the arrows f for automatically winding the screens on their supporting drums when no action is exerted on said screens.
  • Each of the parts A and B of the openable roof is formed from shaped elements, as shown in FIGURE 3. These elements which extend across the entire width of the Waggon, as shown in FIGURE 2, are provided at one of their ends with a portion 9 which is folded twice at right angles and at their other end with an inverted trough like porton 10. The portion 9 of an element is engaged in the trough lit of the adjacent element so that the movement of an element in the direction F (FIGURE 3) or in the opposite direction causes a movement in the same direction of the juxtaposed elements.
  • This junction between the elements works in a hinge-like manner, allowing an element to take up a slanting poistion in relation to the adjacent elements. In particular it allows the winding up of the elements on their drum as shown in FIGURE 1, in which the screen B is shown wound up on its drum 5b.
  • each control means comprising an endless chain 11a, 11b, respectively, passing over pulleys 12a, 12b and over a control wheel 13a, 13b capable of being actuated by a handle.
  • the ends 14a, 14b of the screens are secured to the upper flights of the chains 11a, 11b.
  • Actuation of the wheels 13a, 13b in the direction of the arrows f causes movement of the screens A and B in the direction of the arrows F, which allows the return devices of the drums 5a, 5b to come into action and wind up the corresponding screen on its drurn, thus ensuring the opening of the Waggon.
  • Actuation of the wheels 13a, 13b in a direction opposite to the arrows causes unwinding of the screens A and B to bring them into the position of closing the Waggon.
  • Rainwater received on the screens is evacuated by running out directly along the side edges 6 of the screens A and B.
  • the arrangement of the channels 2a, 2b and angles 7a, 7b forms a bafile and prevents the water from dripping the interior of the Waggon.
  • each channel section 2a, 2b a filling formed of a strip of spongy or absorbing material 15a, 15b, the said filling extending throughout the length of the channel sections these channel sections.
  • a supple joint 16 (see FIGURE 3) carried by the end element 17 of one of the screens which comes into contact with'the suitably shaped end element 18 of the other screen.
  • a gutter 19 may be provided under the joint to ensure the outflow of water at the side edges of the roof.
  • a joint cover 20 may be fixed to one of the screens. Any kind of normal closing device (not shown) such as a bolt or lugs for padlocks, may, of course, be provided if desired, to oppose the opening of the roof.
  • a pull is positively exerted on one or the other ends of the screen during the opening and closing movements thereof, said ends being respectively secured to an endless flexible control member and to the winding drum which may be selectively coupled to an operating mechanism or disengaged therefrom.
  • the coil-springs provided in the winding drums for rotating the drums in the direction opening the screens are no longer essential parts of the structure and can be dispensed with.
  • the sliding sleeve 27 may be moved axially along the shaft 25 by means of a collar 33.
  • the latter is provided with two rods 34 engaged in elongated slots formed in two levers 35a, 35b keyed to a common shaft 36.
  • the end of shaft 36 passes out to the exterior of the casing 21a (or 21b) and is provided with a hand lever 37 (see in particular the left part of FIGURE 4).
  • the end 350 of the lever 35b is pivotally connected to one end of a bar 38, the other end of the latter being pivotally connected to a lever 39.
  • the latter is keyed to a shaft 40a terminating in a hand lever 40.
  • the bar 38 may be moved longitudinally in the direction of the arrow or, conversely, in the direction of the arrow i either by actuating the hand lever 37 disposed in the region of the longitudinal wall 1a of the Waggon (FIGURE 8) or by actuating the hand lever 40 disposed in the region of the other longitudinal wall 1b of the Waggon.
  • Actuation of the bar 38 in the direction of the arrow f5 has for its effect to couple the wheel 24 with the shaft '25, while actuation in the direction of the arrow i causes coupling of the shaft 25 with the wheel 32.
  • a chain 41 is mounted on the wheel 26 and passes over a wheel'42, a tension roller 43 and a driving Wheel 44.
  • the wheel 42 is secured to a shaft 42a on which there is keyed a bevel pinion 45.
  • the latter meshes with another pinion 46 keyed to a shaft 46a which terminates in a crank handle 47.
  • the driving wheel 44 has its shaft 44a secured to a crank handle 48 passing out through the wall 1a of the Waggon while the crank handle 47 passes out through the end wall of the Waggon in the region of the hand lever 37.
  • the shaft 44a extends throughout the width of the Waggon and terminates in a crank handle 49 disposed on the exterior of the wall 1b of the Waggon (FIGURE 8).
  • the wheel 26, and with it the shaft 25, may be driven either by utilising one of the crank handles 47 and 48 disposed towards one of the sides of the Waggon or one of the crank handles 49 and 53 disposed towards the other side of the Waggon.
  • a chain 54 which is subjected to the action of a tension roller 55, is mounted on the wheel 32 and a pinion 56.
  • the latter is keyed on a shaft 56a having secured at its two extremities wheels 57 each carrying an endless chain 58 passing over a counter pulley 59a (or 59b) (see FIGURE 4).
  • On each of the chains 58 is secured the corresponding front element of the screen A or B in the same way as for the chains 11a and 11b in FIG- URE 1.
  • Each of the screens A and B comprises two cups 61, as shown in FIGURES 5 and 7, these cups providing bolt-holes to receive the end of sliding rods 62 constituting bolts for immobising the screen in the closed position.
  • Each of the bolts comprising a rod 62 is constructed as shown in FIGURE 7.
  • the rod 62 is provided at its upper end with a roller 63.
  • the lower part of the rod is hollow and receives the end of a rod 64 comprising a pin 67a engaged in an elongated hole 62a in the rod 62.
  • the latter terminates in a flange 62b against which bears one end of a spring 65.
  • the other end of the spring 65 bears against a plate 66 in which the rod 64 slides.
  • the rod 64 comprises a second pin 67b engaged in an elongated hole 68 disposed at an angle to the horizontal in the coupling bar 38.
  • crank handles 47 and 53 are actuated in the direction of therarrow h, or one of the crank handles 48 and 49 is actuated in the direction of the arrow f the wheel 26 is driven, and as a result the wheel 24 is driven in the direction of the arrow f (FIGURE 5).
  • the drum 22 is therefore driven in the direction to wind up the screen and the latter is brought to the open position in which the rollers 63 are maintained spaced away from the lower face of the screen by the action of the inclined holes 68.
  • one of the hand levers 37 and 40 is first actuated to its end position in the direction of the arrow f (FIGURE 5). This has for its effect, on the one hand, to couple the sliding sleeve 27 and the shaft 25 with the wheel 32 and, on the other hand, to
  • the inclined holes 68 act on the pins 67b to cause upward displacement of the rods 64.
  • the pins 67a slide in the elongated holes 62a of the rods 62, the latter being held in position by the rollers 63 being urged elastically against the lower surface of the screen.
  • the hand levers 37 and 40 may be constrained to rest in the limit position in the direction of the arrow f by any suitable locking means such as seals or the like to keep the screen locked in its closed position.
