Application February 25, 1949, Serial No.- 78,295 2 Claims. (Cl. 15-412) This invention relates to suction cleaners and more particularly to a novel arrangement l of cleaner casing sectio-nsand-the assembly of a motor-fan unit. Y
An object of the invention is to provide a new and improved suction cleaner. Another object is to provide a cleaner casing formed Vin sections which are readily molded or die cast. A further object is to provide a cleaner casing constructed to receive van assembled motor-fan unit to complete the suction cleaner. Other objects and advantages of the invention will be apparent from the following description andv drawings wherein: Figure 1 is a side View with part of the casing removed to illustrate the arrangement of parts; Figure 2 is an exploded view of the parts prior to assembly; and i Figure isa fragmentary bottom view. The embodiment of the invention herein disclosed comprises'a suction cleaner having a body formed Iof casing sections II) and I I anda motorian unit I2 supported within the cleaner body. The casing section II includes a front wall I4 and end walls I5-I5 of :a nozzle I6 provided with a suction air passageway I1 communicating with the fan eye I8 of a fan chazrnberV I9 formed in part by partitions and 2I projecting inwardly from the top wall 22 of the casing section II. Y n
The other casing section I0 forms the nozzle rear wall 26 and has wall po-rtions 23 and 24 which cooperate with the partitions 20 and 2I to form the fan eye I8 and a fan receiving opening for the fan chamber I9. This casing section I0 is provided with two perforated lugs 26 and 29 which receive pins 30 formed on the casing section II, and the pins are riveted to permanently attach the two casing sections together. A fan outlet 3I is formed by the casing sections I0 and II to which is connected an unshown dirt filtering bag.
The casing section II rearwardly of the fan chamber I9 has a top wall 32 and depending side walls 33-33 the latter defining a downwardly facing opening 34 throughwhich the motor-fan unit I2 is inserted for attachment to the cleaner body. Formed integrally with the casing section II are two front wheel supports 35-35 spaced from the adjacent side walls I5, and the latter are each provided with an opening 31 in alignment with a recess 38 at the lower end of each wheel support 35 to receive a pin 39 for a wheel 40, and ay screw 4I extends through the pin 39 into each support 35 to hold the pin and wheel rin position. Formed integrally with the casing 6 motor-fan runit I2 to section II are two rear wheel supports 43--43` provided at their lower ends with a recess 44 each of which cooperates with an apertured boss 45 formed in the adjacent depending side wall 33 to receive a pin 46 on which is mounted aV wheel 41. A screw 48 extends through the pin 46 and is threaded into the boss 45 to attach the pin 46 and wheel 41 to thecasing section II.v j
The openings 31 and recesses36 for the pins 39 supporting the front wheels 40, together with the apertured bosses 45 and the recesses 44 are drilled in the casing section II so that the wheels 40 and 41 are at all times mounted in the same relation with the nozzle mouth 50, whereby all the suction cleaners manufactured will be provided with uniform nozzle height adjustment.,l v
The motor-fan unit I2 includes a beltpulley 52 and a fan 53 both of which are drivenby -an;- unshown shaft of a motor 54 disposed inv ahousing 55 secured at its forward arranged between the fan 53 and housing. 55 The forward end of the housing 55 has a periph-v eral flange 51 provided with three apertured lugs 58 to receive bolts 59 threaded into the lower t casing section I0 to removably secure the motor A recess ,60 is formed be housing 55. thereto. tween the Vtop wall 32 and the ian chamber partiti-on'ZI to. anchor the upper portion of the the motor housing ing section I0 the wall 56 closes the fan receiving opening 25, and the fan 53 and pulley 52 are disposed in the fan chamber I9 and suction air passageway I1. A belt 62 connects the pulley 52 to an unshown surface agitating member movably mounted in the nozzle I6.
Supported in the housing 55 are oppositely disposed motor brushes 63-63 and a U-shaped field stack 64 which has a portion thereof and its coil 65 exposed and projecting beyond the housing 55. on a bracket 61 attached by a screw 68 to the rear end of the motor housing, and a button 69 is removably attached to the switch 66 and projects through an opening 10 in the casing section to receive the operators foot to control the circuit to the motor 54.
Formed in the motor housing 55 are a pair of openings 12 for a shaft 13 which extends through slots 14 in the depending side walls 33-33 of the c-asing section II to rotatably receive the bail 15 of a cleaner handle, to thereby support the handle on the motor housing.
In assembling the cleaner the lower casing section I0 is riveted at 30-30 to the upper casing end to a wall 56v the cleaner body. When, 55 is attached to the lower,- casel A foot operated switch 66 is mounted recess 60 to seat the wall 56 in the periphery of the fan receiving opening 25. VThereafter the bolts 59 are threaded into the lower casing section l to rigidly secure the mo-torefanimit [i2 in the cleaner body. VDuring insertion of the motor-fan unit I2 the switch '66 is yalso properly positioned in the opening to receive the operators foot.
When it is desired to disconnect the motor-*fan unit l2 from the cleaner body, the bolts 59 are removed and the unit pivoted about the recess 69 counterclockwise, as viewed in Figure l, to pass the .lower arcuate portion of the fan chamber wall 56 through the fan receiving opening 25, andl thereafter the motor-fan unit is moved through the opening 34 in the underside of the casing sec tion H.
While we have shown Vand described 'but a single modification of our invention, it is to be understood that this modification is to be taken as illustrative only and not in a limiting sense. We do not wish to be limited to the parti-cular structures shown and described, but to .include all equivalent variations thereof except as limited by the scope of the claims.
We claim:
1. In a suction cleaner, a casing structure formed in two sections, one casing section delining the rear wall of a suction nozzle and part of a 'fan chamber, the other casing .section dening the remaining walls of the suction nozzle, a part of said fan chamber and .having an opening at its underside for inserting a motor-fan unit, said casing sections cooperating to 'provide a fan re,- ceiving opening in said fan chamber for passing a fan therethrough into said fan chamber, said other casing section having means to receive cleaner supporting wheels, a switch opening in said other casing section, a motor-fan assembly inserted 'as a unit through said opening at the un- 4 derside of said other casing section to pass the fan through said fan receiving opening formed by said two casing sections into said fan chamber and the motor into said other casing section, a switch mounted on said motor-fan assembly and having an operating member projecting through said switch opening in said other casing section when said A.motor-fan assembly is positioned in said Casing.
2. In a suction cleaner, a `casing structure 'formed in two sections, one casing section delining therear wall of a suction nozzle and part of a fan chamber, the other casing section defining the remaining walls of said suction nozzle, a part of said fan chamber and having an opening at its underside for inserting a motor-fan unit, said casing .sections cooperating to provide a fan receiving opening in said fan chamber for passing a fan therethrough into said fan chamber, and a motor-fan assembly inserted as a unit through said opening at the Yunderside of said other casing section to pass the fan through said fan receiving opening formed vby said two casing sections into said fan chamber and the motor into said other vcasing section.
