Patented Feb. 29, 1944 UNITED STATES PATENT 4 OFFICE SUCTION CLEANER Arthur M. Harlett. Tiflln, Ohio Application November 1 Y ZCIaims. (oils-156) My invention relates to cleaning apparatus, and has among its objects and advantages the provision of an improved suction cleaner of the portable electric type which may be selectively used for cleaning floors, draperies, walls and the like.

In the accompanying drawings:

Figure l is a front elevational view.

. Figure 2 is a side view having a portionbroken away.

Figure 3 is a plan view of the carriage part of Figure 4 is a sectional view along the line 4-4 of Figure 2.

' Figure 5 is a sectional view along the line 5-! of Figure 4.

Figure 8 is a sectional view along the line 8-8 of Figure 4.

Figure 'l is a view showing a detachable connection between the handle of the carriage and the flexible hose which maybe provided with suitable tools mr cleaning walls, draperies and the like, and I Figure 8 is an end view of a cleaner body or tank cleaner.

In the embodiment oi the invention selected for illustration, I make use of a carriage ll provided with a hood l2 which constitutes a suction nozzle and brush .chamber. Two arms l4 are attached to the hood l2.and carry adjustable supporting wheels ii for holding the mouth end of the hood at predetermined distances from the floor. A rotary brush I8 is located in the hood I! and is supported in bearings 28 attached to the end walls oi the hood.

Two ducts 22 have communication with the hood l2 and with tubular bearings 24 fixed to the ends of the ducts 22 remote from the hood 12. The two ducts are arranged at right angles to the hood i2, and the bearings 24 are coaxial at right angles to the ducts. These parts may comprise a one piece casting, and the hood and the ducts function as a frame for supporting a motor 28 for driving the brush I8 only.

The shaft 28 of the motor 28 projects through an opening 88 in one of the ducts 22 and carries a pulley l2 inside that duct for driving a belt 34 passing around the cylindrical body 36 of the brush l8 to impart rotation to the brush. A pin 38 is fixed to the motor 28 for projection through an opening in a bowed spring 40 having its ends supported on one of the ducts 22. The pulley 82 may be passed through the opening 30, as when the motor is pressed against the bowed spring 48 when placing or removing the'motor with re- 9, 1942, Serial No. 466,178

spect to its supporting frame. The opening 88 is closed by one end of the motor 26, the motor being pressed firmly against that duct..

A duct 42 is fixedly mounted in the bearings 24 and is provided with ports 44 respectively communicating with the ducts 22. Plugs 46 are threaded into the outer ends of the bearings 24 and into engagement with the duct 42 to seal the ends of the duct. The duct 42 is circular in cross section.

Upon the duct 42 and adjacent the inner ends of the bearings 24 are mounted two inner bearing races 48, between which and their respective outer races 58 are mounted needle roller bearings 52. Rubber treads 54 are attached to the outer bearing races 58.

A pivot tube 58 is rotatably mounted upon the duct 42 and is restrained from relative endwise movement through its engagement with the inner bearing races 48. One end of a tubular handle 58 is fixed to the pivot tube 88 and has communication with the duct 42 through the medium of a port 60 in the duct 42.

Upon the handle 58 is detachably mounted a cleaner. body 82, commonly known as a tank cleaner. Such cleaner bodies are old and well known in the art. Suflice it to say that the cleaner body usually comprises a housing cont aining a power plant (a motor and a fan driven thereby) for producing suction at one end and discharging air under pressure at the other.

To one end oi the body 82 is connected a suction hose 64 which, for floor cleaning purposes, has its free end inserted in the handle 58 down to the pivot tube 56. This hose may be withdrawn from the handle for connection with wall and drapery cleaning tools and the like. An airtight connection is provided between the hose and the handle by a sealing flange 88 on the hose for engaging theend of the handle. A flanged nut 68 is threaded on the handle to press the flange 88 into air sealing engagement with the handle. Thus the handle 58 serves as a place of storage for the hose 84.

An eye III is attached to the body 62 and normally engages over a hook I2 attached to the handle 58. Near the lower end of the body 82 is attached a spring clip 14 to releasably engage over the handle. The motor 26 is placed between the ducts 22 of its supporting frame to provide a relatively low carriage, so that the carriage passes easily under furniture, as when the body 62 is removed vi'rom the handle.

The suction cleaner is relatively compact and requires a small storage space. This cleaner also spaced ducts extending transversely from the nozzle; a tubular bearing having communicative connection with each duct and disposed transversely thereof, the outer end of each bearing being closed, a tubular inner duct having its ends fitted in the bearings, the said inner duct being provided with side openings adjacent the ends registering with the spaced ducts and a center opening, and a tubular handle having communicative connection with the center opening in the said inner duct.

2. In a suction cleaner, a nozzle, a pair of spaced ducts extending transversely from the nozzle, a tubular bearing having communicative connection with each duct and disposed transversely thereof, the outer end of each bearing being closed, a tubular inner duct having its ends fitted in the bearings, the said inner duct being provided with side openings adjacent the ends registering with the spaced ducts and a center opening, a pivot tube mounted to turn upon the intermediate portion of the inner duct, roller means mounted on the inner duct between the end bearings and the pivot tube, and a tubular handle connecting with an opening in the pivot tube in registration with the center opening in the inner duct.
