Segesman, Canton, Ohio, assignor to The Hoover Company, North Canton, Ohio, a corporation of Ohio Application January 14, 1955, Serial No. 481,795 9 Claims. (Cl. 183-43) thereto. A further object is to provide a bag container in a suction cleaner and having an opening for insertion of a bag, and a cover to close the opening and secure a dirt conveying conduit to the container. Other objects and advantages of the invention will become apparent from the following description and drawings, wherein:

Figure l is a side elevation of a cleaner embodying the invention,

Figure 2 is an enlarged sectional view through the bag container and the conduit conveying dirt-laden air to the s.

Figure 3 is a rear view of the bag container and conduit showing the cover in open position,

Figure 4 is a perspective view of the filter bag, and

Figure 5 is a composite view showing the attachment of the mounting plate to the filter bag and conduit.

The embodiment of the invention herein disclosed comprises a suction cleaner having a body provided with a nozzle 11 which communicates with a suction air passageway, fan chamber and exhaust passageway all unshown but well known in the art. An unshown motor is supported on the body and operates a fan to draw dirtladen air from thesurface 12 to the nozzle 11 and discharge it through anexhaust outlet 13. The body is supported on front and rear wheels '14 and 15 respectively, the latter being mounted on a spring pressedbracket 16 pivoted to the body at 17.

Projecting rearwardly of the body 10 is a pair of spacedlugs 18 each provided with an opening receiving apin 19 on which is pivotally mounted spacedarms 21 forming part of ahandle 22. The upper end of thearms 21 are secured at 23 to thebottom wall 24 of a rigidfilter bag container 25, and at thetop wall 26 of the latter is attached atubular conduit 27 provided at its upper end with ahand grip 28 to propel the cleaner over thesurface 12. A switch 29 andcord 30 is mounted on thehandle portion 27 for connecting the motor to a source of current. A suitable device indicated generally at 31 controls the positions of thehandle 22.

Thebag container 25 forming part of thehandle 22 is rectangular in cross section and is perforated as indicated at 32 for escape of air. At the upper end of the containerrear wall 33 is anopening 34 for removably inserting afilter bag 35 within thecontainer 25. Acover 36 for theopening 34 is hinged at 37 to theside wall 38 of the container, and asuitable latch 39 on theother side wall 49 locks the cover in closed position.

Aportion 41 of the cover projects rearwardly to enclose and secure theupper portion 42 of aconduit 43 against the containerrear wall 33. Forming part of thecon duit 43 is aflexible bellows 44 connected to the lower end of theconduit portion 42 and to anannular member 45 removably secured to the cleaner body by alatch 46. Theconduit 43 can easily be removed from the cleaner by releasing thelatch 46 and opening thecover 36.

Thebag 35 is formed of filter paper to remove dirt from adirt-laden air stream and has front andrear Walls 47--48 joined at their side edges by a. plurality ofpleats 49 and are permanently sealed together at theiropposite ends 50. Aninlet 51 is formed in thebag front wall 47 adjacent the upper end of the bag. Arectangular mounting plate 52 is provided with aport 53 in register with theinlet 51 and is secured to thefront wall 47 by an adhesive 54 adjacent the marginal edge of theport 53. The adhesive 54 being restricted to the marginal area of theport 53 permits the remainder of theplate 52, as incheated by theopposite end fiaps 55 and 56, to be moved relative to thebag 35. A locatingport 57 is formed in thefree portion 58 of theplate 52 above thebag inlet 51 and receives apin 59 on theconduit 42 to align thebag inlet 51 with anoutlet 60 in the side Wall of theconduit 42. Acord 62 is anchored by abutton 63 to theflap 55 of theplate 52 and is Wound about anotherbutton 64 on the opposite flap 56' to wrap the flaps laterally about the exterior of theconduit 42 to secure thebag 35 thereto. The dirt-laden air in. theconduit 43 is directed through thelateral opening 60 by adeflecting plate 65. p

In order to arrange thebag 35 in itscontainer 25 thelatch 39 is released for movement of thecover 36 to its open position shown in Figure 3 to thereby free thetop portion 42 of the conduit'43 from within thebulge 41 of thecover 36. Theflexible bellows 44 permits movement of theconduit portion 42 away from thecontainer 25 to expose theconduit outlet 60. The locatingpin 59 is then passed through theport 57 on themounting plate 52 to align thebag inlet 51 with theconduit outlet 60. Thereafter theflaps 55 and 56 are wrapped around the conduit and thecord 62 wound on the buttons 63-64 to secure thebag 35 to the conduit. Since thebag 35 is free of themounting plate 52 except for theadhesive area 54 the lower end of the bag can be passed through theinlet 35 into the container and the conduit moved against theback wall 33 of the container to arrange the wrappedmounting plate 52 at theinlet 34 of the container. Movement of thecover 36 to its closed position causes thebulge 41 to engage theconduit portion 42 and thus secure the latter to thecontainer 25 and also maintain thebag 35 within the container. If desired thebag 35 may be inserted within the container prior to attaching themounting plate 52 to theconduit 43.

Operation of the motor causes dirt-laden air to enter the nozzle 11, and pass through theflexible bellows 44, therigid conduit portion 42 and then through thedischarge port 60 into thebag 35 which collects the dirt and permits the cleaned air to pass through theperforations 32 in the container to the atmosphere.

When thefilter 35 is to be replaced thecover 36 is moved to open position exposing thecord 62 which is then unwound from the buttons 63-64 to free thebag 35 from the conduit, and the latter is then moved away from thecontainer 25 to permit removal of thebag 35 through theopening 34.
