Removable protective cover, in particular for rail tank cars The invention relates to a removable protective cover, in particular for rail tank cars. The known protective covers for Eisenbahnkessehvagen consist of heavy wooden, fixed to the carriage frame structures and are therefore uneconomical, .erschweren, and accessibility, as this considerable dismantling of the shell forming parts are necessary. The condition of the boiler and the accessories is therefore not easily verifiable, and as a result, a more frequent check is also not feasible. Although removable protective covers, especially in motor vehicles, are known per se. However, the cases must also be broken down into individual parts.

In contrast, according to the present invention, without such disassembly, easy accessibility of the vessel from both sides and also partly from above and below, is ensured by providing the envelope as a rigid box with flange-like members attached to the upper edge of the slanted sidewalls Approaches centered on the above the. Kessels fixed catwalk is slipped. As a result, the protective cover can be lifted off as a whole without dismantling work. The shell may be made of wood, metal, in particular of light metal. Under certain circumstances also waterproof canvas can be used. - In this case, however, to form the rigid box, a rigid frame must be made, which is then covered with the canvas. The rack can be made dismountable so that it can be collapsed into a parcel for mere transportation purposes that can be carried as usual cargo to the point of use. But even if the walls of the protective cover consist of rigid sheets or boards, it may be advisable to consider the ease of dismantling, so that the sheets and planks can be stacked to save space and also be transported in this condition can. At the point of use they are then assembled into a rigid box, whereby the protective cover a15 whole is placed on the honeycomb and can be quickly removed to provide accessibility, especially for loading and unloading purposes as a whole.

If the cover is mainly used for protection against the sun's rays, then it is expedient to provide openings on the front sides so that the air can pass through. Likewise, sufficient air can be left between the walls and the cart frame to aid cooling by the natural draft. If the shell rests with the walls on the frame, so suffice in this case a corresponding number of webs. It is more advantageous, however, if it is reasonable not to support the shell with its lower edge on the frame, but hang it with its upper part, in particular with the roof part. On the other hand, if the shell mainly serves for cold insulation, then it is appropriate placed with its lower edge, directly on the car body or the car floor and supported exclusively here. The still air between the shell and the load actually acts as good insulation. However, it can still be supported by installing a special heater, such as a hot air heater, which is located in the lower part of the car and is set before, during or after the trip in action.

The invention is illustrated in the drawing, for example.

Fig. I. and FIG. 2 show, in cross-section, an exemplary embodiment in application for a railroad tank car.

As shown in Fig. I and 2, a placed in the middle catwalk a b arranged in the middle, which also forms the roof part of the protective cover. However, this part is fixed, though detachable on the boiler, supported by the supports e. The protective railing d is attached to it.

The remaining part of the protective cover is formed by the side walls e, which are chamfered in the upper part, and corresponding Stirnwiinde f.

According to Fig. I, the removable protective cover is carried by the catwalk b by the protective cover at J angles over the rim.

The protective cover in Fig. I is mainly designed for protection against the sun's rays. Accordingly, a wide ventilation strip is left between the lower edge and the carriage bottom. Also holes i are provided in the end walls, which favor a continuous draft while driving.

In contrast, in the embodiment according to Fig. 2, the protective cover for insulation against external influences of cold dimensioned. The protective cover encloses the entire lines and fittings, extends to the car floor h and sits on these by means of the contact angle k. These wear in the main the protective cover, however, participate the upper board angle g mainly on the leadership or centering of the protective cover. In Fig. 2 is also the arrangement of a hot air heater l indicated.
