SUCTION CLEANER 2 sheets-sheet 1 Filed May 22, 1939 INVENTOR ATTORNEY Oct. 21', 1941. P. T. HAHN SUCTION CLEANER Filed May 22, 19:59 Z-Sheets-Sheet 2 ATTORNEY Patented I 21, 1941 corporation of Ohio Application May 22, 1939, Serial No. 274,907

7 Claims.

The present invention relates to suction cleaners in general and particularly to a new and novel element-supporting unit for supporting the suction cleaner handle, dust bag and rear wheels. More specifically the.invention comprises a single metal stamping so formed as to include a support for mounting the handle, dust bag and rear wheels on the cleaner casing.

It is an object of the present invention to provide a new and improved suction cleaner. It is another object to provide a new and improved metal stamping for supporting the suction cleaner handle, dust bag and rear wheels on the cleaner casing. Another object is to provide a new and improved unit for supporting cleaner elements and which permits economy in manufacture. Still another object is to provide a new and 'novel method of suction cleaner assembly. Other objects and advantages of the invention will be apparent upon reading the following spec-.

ification and claims and the attached drawings,

the upwardly curved exhaust passageway and the manner of attaching a flexible bellows thereto;

Figure 4 is a perspective view of the rear end of the cleaner casing;

Figure 5 is a rear perspective view of the cleaner element-supporting unit, and

Figure 6 is a front perspective View of the construction shown in Figure 5.

An embodiment of the invention is disclosed in a suction cleaner comprising a main casing I having an outer casing ll provided with a nozzle I2, a flat top wall l3, depending contoured side skirts l4, and an end wall IS on opposite sides of an exhaust passageway 16. An inner casing is'supported in the nozzle I2 and is connected by a belt 28 to an unshown motor mounted on the main casing II and enclosed in a housing 29.

20 cooperates with the outer casing H to form an unshown fan chamber and the exhaust passageway IS, the inner casing being provided with flanges 2| for connection to the outer casing H. The exhaust passageway l6 projects beyond the rear wall l of the outer casing to form a collar 22 the lower wall 23 thereof being curved up- An agitator 21 In the present embodiment the means for mounting the usual cleaner elements such as the rear wheel bracket, bag flange, and handle support are formed from'a single piece of stamped metal to provide unitary element-supporting means. The element-supporting unit is indicated generally at 30 and comprises a substantially circular body or exhaust flange 3| provided with an opening 32 and upper and

lower flanges

33 and 34 respectively. The opening 32 receives the exhaust collar 22 and the

flanges

33 and 34 are welded to the outer and inner casings II and respectively and the exhaust flange 3| is welded to the rear casing wall I5. In order to properly position the element-supporting unit on the main casing, the flanges 2| on the latter project through spaced offset slots 36 in the exhaust flange 3|.

Projecting rearwardly from the exhaust flange 3| and struck out from the latter is a pair of spaced arms 38 provided with openings 39 to support a pin 40 on which is pivotally mounted a bracket 4| that supports the upper end of a flexible bellows 42 having its lower end 43telescoped about the projecting exhaust collar 22 as shown in Figure 3. A suitable bag clamp 44 is mounted on thebracket 4| for removably securing afllter bag 45 thereto.

Formed integrally onthe element-supporting unit 30 is a circular bag flange 4! whichextends rearwardly of the exhaust flange 3| and about which the lower end 48 of a bag 49 is removably attached by suitable bag clamping means. The

two

bags

45 and 49 are suitably supported at their upper ends so as to move with the cleaner handle, the bellows 42 flexing during movement of the bag 45.

Also formed integrally with the "element-supproject forwardly and upwardly from the periphery of the exhaust flange 3|, and a member 51 arranged at an angle to the side arms 56 welded to the inner casing 20. Depending from the side arms 56 are a pair of spaced legs 59 provided with openings 60 to receive a shaft 6| which supports the rear wheels 62. The front end ofthe cleaner is supported on wheels 63 which are carried by the outer casing H.

Stamped integrally with the element-supporting unit '30 is a handle bracket 65 which extends downwardly and forwardly of the exhaust flange 3| andhas a bottom -wall as and upwardly exelements of a suction cleaner comprising, a body tending side walls 61, the bottom wall 68 being In order to control the position of the handle.

with respect to the cleaner casing, segment means .are formed on the lower defining edge of one of the handle socket side walls and includes a re cess 15, a stop 18 and interposed therebetween an irregular segment surface 11. A' handle control lever 18 is pivotally supported on a pin 19 /carried by an arm 80 struck out fromthe back wall 86 of the handle bracket and by an arm 8| extending from the exhaust flange 3|. Projecting from the control lever 18 is a pawl 83 which engages the segment means to hold the handle in selected operating positions. A foot pedal 85 is formed integrally with the lever 18 to actuate the latter.. Asp'ring 861sanchored at one end about a depressed. collar 89- in the control lever I8 and its opposite end is: seated in an opening 80 formed in a portion 5!: of the handle bracket 65. When the foot pedal 18 is depressed the pawl 83 is removed from the segment means and permits free movement of the handle to thedesired position,

and when the pedal is released the spring 86 urges the pawl 83 into engagement with the segment to hold the handle in adjusted position.

From the foregoing it will be perceived that the element-supporting unit 30 is formed from one piece of metal and dies, shaped to press contour, to form the handle bracket the metal to the desired 65, wheel bracket 55, exhaust flange3l, bag-flange 41, tabs 38 to support the articulated bag 45 latter will move with the handle, and tabs 80 and so that the 8| to support the handle control means. Although the casings and element-supporting unit are welded together equivalent securing means may be used.
