The object of the invention is to improve and simplify the construction and operation oi' devices ot' this character and thereby rendcr them less expensive and more durable and efficient. v I
.lilith the above and other objects in view, the invention consists of the novel features ot construction and the combination and arrangement ot' 'parts hereinafter full)Y described and claimed. and illustrated in the accompanying drawings. in which-4- Figure 'l is an end elevation of the iinproved exhauste'r or suction fan; Fig. 2 is a vertical section taken on the plane indi,- ca'ted bv the line 2HE in Fig. l; Fig. 3' is a vertical transverse section taken on' the plane indicated by the line 2%*3 in Fig. 2:
tari' fan. V v
ln the drawings l denotes4 a substantially cylindrical casing containing a'- i'ota r v fan 2 and consistingofa cylindrical iodv and Fig. 4f 1s a perspective view of'thc ifo-- i t) at its` ends with i'a'di'allji projecting annular flanges l" to which are riveted oi otherwise sccnrcd two circular lheat 5.13. ljpon the c vliiidrical bod)Y 3 of .the casingfis provided a suitable base T and. formed integral with it adjacent to itsl bottom is an `outlet pipe S. The fan Q is fixed to one cnd ot a transverse shaft 9 jonriialed in spaced l'icaring.` l0 o n a bracket ll'. which latter ifs-secured 'to the head f. Fixed to said shaft between thc bearing.` i() is' a pulley l2 ovcr which is.
puh-cda .suitable driving belt. Formed in thc center ot' thc head (Tisl an inlet opening lil whichv is .surrounded bv' a cone-shaped or tunnel-shaped member .l-l having a reduced tubular connection 15 for thc attachment ot a hos-c of tiexiblc tube not illustrated) which carries thc suction head or nozzle.
is a specification, lreference- The fan Qooinprises a hub 16 fixed to the 55 end of the 'shaft 9 which projects into the casing, a plurality of radiating spokes 17 tei'iiiinating at their outenends in broad iaty blades'ltl. and two annular plates or rings 19` which ai'e united t0 the opposite edges of 65 the blades 18 by fastenings passed Ithrough said. plates and. through apertured ears 20 formed on the side edges of the blades, as
' shown in Fig. 2.
The inlet opening 121 in the fan casing is 65. or the saine diameter as the opening in the adjacent side plate oi' ring` 19 of the tan so that as the latter is rotated in the direction indicated by' the arrow in Fig. 2. air will be drawn in 'through the fltunel-shaped rednc- 70 ing member 14j and -will be-t'orced b v the blades ofthe wheel out of theV casing through the outlet pipe which latter may lead to an'v suitable point of discharge. By constructing the wheel as shown with the broad' 75 blades united by the side platesI and arranging` the saine 'within a casing havinga large inlet provided with a reducing connection,v a
v ver v cttective exhaust device is produced.
and one. which will be strongvand durable in 80 use and capable ot.' 'being operated with -ta small expenditureot power.'
