French and George Sporney, Chicago, 111., assignors to Birtman Electric Company, a corporation of Illinois Application November 2, 1944, Serial No. 561,538 '7 Claims. (Cl. 183-36) 2 1 This invention relates to a suction cleaner and more particularly to a suction cleaner of the tank type in which a cast tank housing is split on a portion of the housing forms a dust collecting chamber M which contains the dust bag 33. Ad jacent this chamber is a ?lter chamber 50 con substantially central ‘and horizontal plane to form upper and lower housing members and is provided with integrally cast transverse vertical walls which form seats for the motor of the suction taining a ?lter 5| which may consist of a screen 52 having a cloth cover 53. This screen is car ried in a semi-annular groove 54 in the lower housing member and is pressed against a semi annular plate 55 in the upper housing member by a semi-annular stud 5B which is an integral The invention is illustrated in the drawings in which Figure 1 is a side elevation of the housing; 10 part of the rear upper housing member 29. When the lid 29 is raised, the stud 56 is also Figure‘2 is a plan View thereof; Figure 3 is an raised, thereby freeing the upper portion of the end elevation thereof from one end-of th'ecleaner; ?lter. The ?lter is flexible and may be bent suffi Figure 4 is an end elevation of the other end of ciently to the rear to grasp it and withdraw it the cleaner; Figure 5a is a sectional elevation of the motor end of the housing; Figure 5b is a sim 15 from the groove 54. In order to form an air tight connection, the stud 56 is provided with a ilar View or” the other end of the housing; Fig groove 5‘! into which the ?ange 58 penetrates. ure 6 is a sectional elevation taken along the line Immediately adjacent the flange 58 is a semi-an 6—5 in Figure 5a; Figure '7 is a similar view taken nular groove 59 containing a gasket 68 against along the linel-‘l in Figure 5a; Figure 8 is a which the stud 56 presses to seal the ?lter in the similar view taken along the line 8-8 in Figure upper half of the housing. The engagement with 5a; and Figure 9 is a fragmentary plan view of the groove 54 is sufficiently tight to seal the lower the lower housing member illustrating the flow of half of the ?lter. air from the fan chamber to the exhaust. Immediately to the rear of the ?lter chamber The cleaner comprises the housing 28 which 50 there is a fan chamber 70. The split wall 'll is split on the horizontal plane 2| into an upper between the ?lter chamber and the fan chamber housing member 22 and a lower housing member de?nes one side of the fan chamber and is pro 23. The upper housing member is provided with vided with a metal sleeve 12 which directs air a, handle 2a. This handle is made up of a stud from the ?lter chamber into the fan 13. This '25 which is an integral part of the casting, the handle proper 26 which is secured to the studs by 30 fan comprises sheet metal walls 74 and 15 be tween which are mounted a plurality of curved any appropriate fastening and the arms 27 which blades which direct the air outwardly as indi are pivotally mounted on the handle proper at 28 cated by the arrows in Figure 5. The fan is as shown in Figure '7. The arms 2'! are an inte driven by the extension 76 of the motor shaft ll. gral part of the front portion 29.0f the upper Behind the wall '75 is a secondary chamber 18 housing member. ‘This rear portion forms ‘a re Within which are mounted a plurality of station movable lid which is latched to the lower housing ary blades '19 carried by the metal plate 80 which member 23 by any appropriate latching device 30. is mounted by a ?ange Si in the split partition The lid is provided with an air inlet 3| having an wall 82. The internal edges of this wall define annular groove 32 adapted to engage the ordinary hose. The lid also carries a dust bag 33 having 40 a circular opening within which the flange BI is ?tted. A second rotary fan 99 likewise car a substantially rigid neck portion 34 .provided ried by the shaft extension 16 forms the third with a ?ange 35 having a resilient annular gas division of the fan chamber. This fan, like the ket 36. ?rst, comprises a pair of spaced parallel sheet The lid is provided with‘ a semi-annular grooved stud 3'! within which the ?ange 35 may be slid 45 metal Walls 9| and 92 having curved blades 93 which direct the air outwardly toward the walls from below, when the lid has been raised.
