1,390,950 9/1921 7 Claims, 4 Drawing Figures Avery 98/115 R ADJUSTABLE ASSEMBLY FOR EXHAUSTING OUT FUMES The present invention relates to an adjustable assembly for exhausting fumes from working places where unhealthy gases are formed, said assembly, among other things, comprising a suction fan, a suction casing and a flexible tubing extending between the suction casing and the fan. A suitable application for the assembly may for example include the exhausting of fumes by welding and the like operations.
Previously known suction devices have shown several drawbacks; the primary drawback being the difficulty to easily adjust and according to the progress of the work move the actual suction casing or suction nozzle so that an effective exhausting of all the fumes has been made possible.
The suction assembly according to the present invention has for its object to eliminate the above mentioned and also other drawbacks and in the following an examplifying embodiment will be described with reference ,to the accompanying drawings, in which FIG. 1 shows a side view of the suction assembly, partly in section, FIG. 2 also shows a side view of the assembly arranged in three different positions, FIG. 3 illustrates a view seen from above of the three different positions according to FIG. 2, and FIG. 4 on a more enlarged scale illustrates the different links of the assembly in detail.
With reference being made to FIG. 1 a suction fan is indicated by l,numeral 2 designates a suction casing and a flexible tubing 3 extends between the fan and the suction cover. Hereby, the fan comprises a motor 4 driving the fan wheel (not shown) and a fan cap 5, a central pipe 6 extending from the cap and an elbow 7 being pivotably mounted on the pipe. One or more plates 8 are fixed to the free end of the elbow 7, said plates forming the bearings for a first linkable arm 9 as well as for one or more springs 10, being shown only schematically by dotted lines in FIG. 1. To the end of the first linkable arm 9 remote from the fan an essentially triangularly shaped plate 11 is fixed, said plate forming the attachment for a second linkable arm 12 and for one or several more tension springs 13. The other end of the spring 13 is fixed to a flange 14 extending from the arm 12, said flange being positioned close to the outermost end of the arm 12. The suction casing 2 is at 15 pivotallyfixed to said outermost end of the arm 12, which cover is suitably provided with a handle 16 and a fly 17 indicated by the dotted lines. The suction casing 2 is pivotable relative to the arm 12 in the direction shown by the arrow 18.The flexible tubing 3, preferably made from a glassfibre-reinforced thermostable plastic material is thread outside the elbow 7 at one end thereof and outside the suction casing 2 at the other end thereof.
In FIG. 2 and 3 the assembly is shown in three different positions, where position A is the positionin which the suction casing 2 has the smallest distance to the wall 19 or similar structure on which the assembly is hung. The positions B and C are showing the maximal distance from the suction casing to the wall 19 and a position, respectively, in which the suction casing takes a position, that lies on a distance between the two positions A and B but on a higher level than in these two positions. The pivotal mounting of the assembly in the horizontal plane is preferably illustrated in FIG. 3.
FIG. 4 in detail shows the litiks and the securing means for the tension springs and includes the same reference numerals as used in FIG. 1 for the common details of the two figures. The arm 9 extends from the plates 8, said arm being fixed to theplates by a screwed bolt and nut, the centre line of which is marked by the dotted line 20. Friction washers 21 are positioned between the arm 9 and the plates 8, said washers preferably being made from bakelite reinforced with fabric. The plates 11 are welded to the other end of the arm 9, as indicated by 22. The arm 12 extends from the plates 11, said arm being fixed to these in a manner similar to that in which the arm 9 is fixed to the plates 8. In this case the friction link 23 comprises washers 24, one side thereof engaging the arm 12 and the other side thereof engaging the friction washers 25, which in turn at the other side thereof directly engages the plates 11. To ensure the friction force flat washers 26 and spring washers 27 are positioned between the plate 11 and the bolt or nut 28 and 29, respectively. Shafts 30, 31, respectively, extend through the plates 8 and 11 and the ends of the tension springs are fixed to said shafts. Thereby the shaft 30 supports one end of the springs 10 and the shaft supports the other end of the springs 10 as well as one end of the springs 13, whereby in this case the springs 13 are fixed outside thesprings 10. The other end of the springs 13 is fixedl to a shaft extending through the flange 14 positioned on the arm 12.
As is understood, the invention may be varied in several ways within the scope of the following claims, without departing fromthe spirit of the invention.
