(Cl. 105377) 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.

Yet another object of this invention is to provide an openable root device for a car having the characteristics herein above specified, further ensuring inviolability of the contents of the car by having means for placing leads or seals.

Other objects and advantages of this invention will be apparent from the following description taken in conjunction with the accompanying drawings in which:

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. I

In the embodiment shown in FIGURES 1 to 3, the openable roof is formed in two parts A and B each constituting a movable screen.

Along the longitudinal walls 1a and 1b of the Waggon are fixed channels 2a, 2b the flanges of which are directed upwardly.

On the end walls 3a, 3b of the Waggon are fixed 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). Preferably 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.

The side edges 6 of these screens are engaged under the horizontal flanges of angles 7a, 7b disposed parallel to the channels 2a, 2b and fixed to supports 8a, 8b secured to the walls la, 112.

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.

Individual operation of the screens A and B is ensured by a control means for each of them, 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.

- It is advantageous to provide between the flanges of 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.

In order to obtain a suitable water-tightness between the two parts of the roof, there may be provided 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. In addition 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.

By reason of the folded section or ribbed form of the elements forming the parts A and B of the openable roof, which elements are preferably made of sheet iron,

jected, which deformationsmay be very considerable.

In a modified form of the above described car, 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. In such a case 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.

v Referring now to FIGURES 48, the winding drum 22 of each of the screens A and B is connected by a chain 23 to a wheel 24 mounted loosely on a shaft 25. On this shaft'25, which constitutes the control shaft previously referred to, is keyed a wheel 26 which can be driven manually as will be described hereinafter.

On the shaft there is also keyed against rotation a sliding sleeve 27 comprising on its end faces

dogs

28 and 29

opposite dogs

30 and 31 provided on a wheel 32 mounted loosely on shaft 25 and the wheel 24, respectively. V

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). By actuating the hand lever 37 in the direction of the arrow i coupling of the sleeve 27 with the wheel 24 is effected, while actuation of the hand lever 37 in the direction of the arrow f brings the sleeve 27' into mesh with the wheel 32. a

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.

r A chain 41 is mounted on the wheel 26 and passes over a wheel'42, a tension roller 43 and a driving Wheel 44.

4 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). In addition, on the shaft 46a is keyed a wheel 50 on which is mounted a chain 59a passing over another wheel 51 keyed on a shaft 52 which terminates in a crank handle 53. 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.

The operation of the mechanism described above takes place as follows for each of the screens A and B:

Let it be assumed that the screen is in the closed position (Le. the position of the screen A in FIGURE 4). If it is desired to bring the screen to the open position, one of the hand levers 37 and 40 is first actuated to its end position in the direction of the arrow A (FIGURE 5). The result of this is to move the coupling bar 38 in the direction of the arrow f Thus the sliding sleeve 27 is brought into mesh with the wheel 24 and the rods 64 are moved downwardly in the direction of the arrow f by the inclined holes 68. The rods 62 are themselves lowered by the pins 67a engaging the lower ends of the elongated holes 62a, the end of each rod 62 thus being disengaged from the corresponding cup 61, and the screen is unbolted.

If now one of the crank handles 47 and 53 is 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.

To reclose the screen, 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

move the coupling bar 38 in the direction of the arrow i The inclined holes 68 act on the pins 67b to cause upward displacement of the rods 64. In this displacement 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.

By actuating one of the crank handles 47 and 53- in the direction of the arrow f or one of the crank handles 48 and 49 in the direction of the arrow f rotation of the shaft 25 is effected and as a result the wheel 32 rotates in the direction opposite to that of the arrow i The chain 54 transmits this movement to the shaft 56a and as a result the chains 58 are moved in the direction of the arrow to close the screen.

When the forward edge of the screen comes to the end of its closing movement the cups 61 will be brought opposite the rods 62. The latter, under the action of the springs 65, which have been maintained under compression since the hand levers 37 and 40 were brought to their limit positions in the direction of the arrow 12,, will enter into the cups 61 for bolting the screen in the closed position.

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.

Of course modifications may be made to the embodiments of the invention which have been described above, in particular by the substitution of equivalent mechanical means, without thereby departing from the scope of the invention as defined in the ensuing claims.
