Joseph John DOYLE in Tralee / Ireland Wind hood for chimneys or the like

The innovation concerns wind hoods, especially for chimneys and / or other smoke or exhaust gas outlets.

The innovation creates a wind hood which has a housing with a device for receiving a smoke or exhaust pipe and a shield arranged above this device in the housing and held by the housing A further innovation is proposed a wind hood which has a housing on which a smoke or exhaust pipe which is set up for attachment to a smoke or exhaust gas outlet opening, and holds a shield arranged inside the housing above the outlet opening of the smoke or exhaust gas pipe.

In a special embodiment of the innovation is the housing tubular or cylindrical and equiaxed attached to a pipe section, while the shield is in the form of a Has pipe or tubular element of smaller diameter than that of the housing, from the housing within the same equiaxed to him and above the outlet opening of the pipe section is held and is preferably closed at the upper end with a lid.

Further features emerge from the subclaims.

The innovation is preferred in the following with reference to the accompanying drawings using one given only as an example Embodiment explained. In the drawing show:

Fig. 1 is a view of a windshield according to the innovation with parts broken away to show interior details;

Fig. 2 is a section of the wind hood along the line II-II of Fig. 3 and

FIG. 3 shows a section (elevation) of the wind hood along the line III · III in FIG. 2.

As shown in the drawings, the smoke outlet or chimney has a smoke outlet pipe section 1, which holds a cylindrical housing 2, which in turn holds a shield formed in the form of a pipe section 3, which is preferably closed at the upper end by a cover 10 firmly connected to it or formed in one piece with it. Both the cylindrical housing 2 and the pipe section 3 are coaxial with the smoke outlet pipe section 1.

At the outlet end of the smoke outlet pipe section 1 is an annular one Windbreaker element 4 and a similar element 5 is arranged at the adjacent end of the pipe section 3. From the smoke outlet pipe section four retaining plates 6 extend outwards, which are separated from one another and arranged at angular distances of 90 ° from one another and the cylindrical housing 2 with the smoke outlet pipe section 1 rigidly connect.

The pipe section 3 is held in the cylindrical housing by four further plates 7. The pipe section 1 is also with

Additional support plates 9 are provided, by means of which the wind hood can be attached in or on a smoke or exhaust outlet, not shown.

At its upper end, the housing is provided with a wire mesh or cover 8, which is used, among other things, to build bird nests to prevent in the wind hood.

The arrows shown in Fig. 3 indicate the directions in which the products of combustion emerging from the smoke outlet opening normally pour.

It should be pointed out that in a preferred embodiment according to the innovation, unfavorable weather conditions do not generate downward currents and do not impede the escape of combustion products to the atmosphere. Due to the construction and the ingress of rain into the outlet or chimney is prevented.

Certain common windshields are not susceptible to corrosion at the so-called hot point. In a wind hood according to the invention for chimneys, an air space is provided between the so-called hot point around the upper surface of the wind hood, which reduces the risk of corrosion.
