sucTIoN CLEANERS Filed Jan. 14. 1955 3 Sheets-Sheet 2 3v n W March 12, 1957 Filed Jan. 14. 1955 L. E. SEGESMAN SUCTION CLEANERS 3 Sheets-Sheet 3 United States Patent SUCTION CLEANERS Louis E. 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 the surface 12 to the nozzle 11 and discharge it through an exhaust outlet 13. The body is supported on front and rear wheels '14 and 15 respectively, the latter being mounted on a spring pressed bracket 16 pivoted to the body at 17.

Projecting rearwardly of the body 10 is a pair of spaced lugs 18 each provided with an opening receiving a pin 19 on which is pivotally mounted spaced arms 21 forming part of a handle 22. The upper end of the arms 21 are secured at 23 to the bottom wall 24 of a rigid filter bag container 25, and at the top wall 26 of the latter is attached a tubular conduit 27 provided at its upper end with a hand grip 28 to propel the cleaner over the surface 12. A switch 29 and cord 30 is mounted on the handle portion 27 for connecting the motor to a source of current. A suitable device indicated generally at 31 controls the positions of the handle 22.

The bag container 25 forming part of the handle 22 is rectangular in cross section and is perforated as indicated at 32 for escape of air. At the upper end of the container rear wall 33 is an opening 34 for removably inserting a filter bag 35 within the container 25. A cover 36 for the opening 34 is hinged at 37 to the side wall 38 of the container, and a suitable latch 39 on the other side wall 49 locks the cover in closed position.

ice

A portion 41 of the cover projects rearwardly to enclose and secure the upper portion 42 of a conduit 43 against the container rear wall 33. Forming part of the con duit 43 is a flexible bellows 44 connected to the lower end of the conduit portion 42 and to an annular member 45 removably secured to the cleaner body by a latch 46. The conduit 43 can easily be removed from the cleaner by releasing the latch 46 and opening the cover 36.

The bag 35 is formed of filter paper to remove dirt from adirt-laden air stream and has front and rear Walls 47--48 joined at their side edges by a. plurality of pleats 49 and are permanently sealed together at their opposite ends 50. An inlet 51 is formed in the bag front wall 47 adjacent the upper end of the bag. A rectangular mounting plate 52 is provided with a port 53 in register with the inlet 51 and is secured to the front wall 47 by an adhesive 54 adjacent the marginal edge of the port 53. The adhesive 54 being restricted to the marginal area of the port 53 permits the remainder of the plate 52, as incheated by the opposite end fiaps 55 and 56, to be moved relative to the bag 35. A locating port 57 is formed in the free portion 58 of the plate 52 above the bag inlet 51 and receives a pin 59 on the conduit 42 to align the bag inlet 51 with an outlet 60 in the side Wall of the conduit 42. A cord 62 is anchored by a button 63 to the flap 55 of the plate 52 and is Wound about another button 64 on the opposite flap 56' to wrap the flaps laterally about the exterior of the conduit 42 to secure the bag 35 thereto. The dirt-laden air in. the conduit 43 is directed through the lateral opening 60 by a deflecting plate 65. p

In order to arrange the bag 35 in its container 25 the latch 39 is released for movement of the cover 36 to its open position shown in Figure 3 to thereby free the top portion 42 of the conduit'43 from within the bulge 41 of the cover 36. The flexible bellows 44 permits movement of the conduit portion 42 away from the container 25 to expose the conduit outlet 60. The locating pin 59 is then passed through the port 57 on the mounting plate 52 to align the bag inlet 51 with the conduit outlet 60. Thereafter the flaps 55 and 56 are wrapped around the conduit and the cord 62 wound on the buttons 63-64 to secure the bag 35 to the conduit. Since the bag 35 is free of the mounting plate 52 except for the adhesive area 54 the lower end of the bag can be passed through the inlet 35 into the container and the conduit moved against the back wall 33 of the container to arrange the wrapped mounting plate 52 at the inlet 34 of the container. Movement of the cover 36 to its closed position causes the bulge 41 to engage the conduit portion 42 and thus secure the latter to the container 25 and also maintain the bag 35 within the container. If desired the bag 35 may be inserted within the container prior to attaching the mounting plate 52 to the conduit 43.

Operation of the motor causes dirt-laden air to enter the nozzle 11, and pass through the flexible bellows 44, the rigid conduit portion 42 and then through the discharge port 60 into the bag 35 which collects the dirt and permits the cleaned air to pass through the perforations 32 in the container to the atmosphere.

When the filter 35 is to be replaced the cover 36 is moved to open position exposing the cord 62 which is then unwound from the buttons 63-64 to free the bag 35 from the conduit, and the latter is then moved away from the container 25 to permit removal of the bag 35 through the opening 34.

While I have shown and described but one embodiment of my invention, it is to be understood that this embodiment is to be taken as illustrative only and not in a limiting sense. I do not wish to be limited to the particular structure shown and described but to include all equivalent variations except as limited by the scope of the claims.
