VACUUM CLEANER Filed April 13, 1936 z \INVENTOR ATTORNEY Patented Oct. 13, 1936 PATENT AOFFlCE- VACUUM cnnmsa Frederick Riebel, Jr., Toledo, Ohio, assignor to Air-Way Electric Appliance Corporation, Toledo, Ohio, a corporation of Delaware Application April 13, 1936, Serial No. 74,050

7 Claims. (CI. 15-16) This invention relates to vacuum cleaners and has as its object to provide a vacuum cleaner in which the fan casing is stationary and has a two part telescoping outlet, one section of which is integral with the fan casing and the other section of which is rigidly attached to the handle so as to move in unison therewith and with the bag which is suspended below the handle and attached to the outlet. 7

Further objects will appear in the perusal of the following detailed description of the invention in connection with the accompanying drawing, in which:

Fig. 1 is a plan view of a vacuum cleaner embodying the invention, parts being broken to better illustrate the construction.

Fig. 2 is a vertical longitudinal sectional view taken on the line 22 of Fig. 1, and

Fig. '3 is a transverse vertical sectional view' taken on the line 3-3 of Fig. 2. v

The invention provides a wheel mounted body unit comprising, generally, the suction chamber l0, suction fan I5, I8 and motor 22. The chamber Ill is provided with suction elbows H projecting upwardly from, communicating with, and

secured to the bifurcated rear portions l2 thereof. The elbows II have wide flanges l3 secln-ed to the side walls l4 of the. fan case l5 over the openings H5 in said side walls, and form the fan inlets Mia. The fan case l5 has a central partition wall .I'I forming two fan chambers in which the two fan impellers l8 operate. The impellers 49 are mounted upon a shaft l9 which in turn is journalled in bearings 20 mounted in sleeves 2i mounted in the elbows H.

A motor 22, mounted in a depression 23 in the suction chamber I9, on resilient mountings 24, drives the shaft l9 by means of belts 25, and drives the rotary agitator 26 by means of a belt 21. The agitator 26 embodies flexibly mounted beater elements 28 and brush elements 29. The

belt 21 passes through a slot 39 in the top wall of the body l0.

The motor 22 and elbows H are covered by a cover 3|, having a bumper 32 terminating at its lower end in a headlight hood 33, of soft rubber.- The body of the bumper is vulcanized upon a position to direct light rays beneath the hood 33 through the opening 35 in the cover.

The suction chamber I0 is mounted on. front I packing 52.

wheels 36 and rearwheels 31, the latter carried by a frame 38 the forward end of which is pivoted to the knuckle 39 in which is socketed the end of an adjusting screw 40 threaded through a boss 4| on the body In. The frame 38 is fulcrumed 5 at 42 on the bifurcated conduits l2.

The fan case l5 has a discharge conduit 43 the longitudinal axis of which lies on an arc of a circle having its center on the axis of the pivots 44 of the handle bail 45 of the handle 46. Formed integrally with the ball 45 is the bandlesocket 41 in which the handle 46 is secured,

and which carries the outlet elbow 48 of a swinging discharge conduit 49. l

The swinging conduit 49 is telescoped over the 15 conduit 43, and curved to receive the same. The end of the conduit 43 has a fiange'50. Threaded into the end of the conduit 43 is a collar 5| between which and the flange 50 is a ring of packing material 52. 20

The conduit 49 is detachably secured to the elbow 48 as by screws 53, to facilitate by its removal, access to the packing ring 52.

Mounted in the elbow 48 is the bag coupler, 54, which provides communication to the bag 55. 25 The bag is suspended on rods 58 the ends of which are socketed in the web 5! connecting the socket 41 and the elbow 48.

The outer conduit 49 has sufficient range of movement relative to the inner conduit 43 to 30 allow the handle to move from a horizontal to a vertical position. At any position intermediate such terminal positions, the

conduits

43 and 49 together form a closed exhaust outlet from the fan chamber to the bag connector. A 35 flexible, stretchable, collapsible tube 58 may or may not be employed to enclose the

telescoping conduits

43 and 49. It is secured at its ends to the respective conduits, and seals them against the escape of. any dust that might leak past the 40 The tube 58 may be removed to v clean out the dust collected by it. It is arranged to not interfere with the movement of the conduit 49.

I I claim as my invention: 5

1. In avacuum cleaner, a body unit including 7 a stationary fan casing, a handle hingedly attached to said body unit, and an exhaust outlet for said fan casing including telescoping arcuate tubular members attached respectively to the 50 handle and to the fan casing, their longitudinal arcuate axes being concentric with the axis of swinging movement of the handle.

2. In a vacuum cleaner, a body unit including a stationary fan casing, a handle hingedly attached to said body unit, and an exhaust outlet for said fan casing including telescoping arcuate tubular members rigidly attached to and integrally formed on, respectively, the handle and fan casing, their longitudinal arcuate axes being concentric with the axis of swinging movement of the handle.

3. In a vacuum cleaner, a body unit including a fan casing, a handle hingedly attached to said body unit, and an exhaust outlet for said fan casing including telescoping arcuate tubular members attached respectively to the handle and to'the fan'casing, their longitudinal arcuate axes being concentric with the axis 'of swinging movement of the handle, and packing means disposed between said tubular members.

4. In a vacuum cleaner, 9, body unit including a stationary fan casing, a handle hingedly attached to said body unit, and an exhaust outlet for said fan casing including telescoping arcuate tubular members attached respectively to the handle and to the fan casing, their longitudinal arcuate axes being concentric with the axis of swinging movement of the handle, said outlet being disposed chiefly below the fan casing.

5. In a vacuum cleaner, a body unit including a stationary fan casing, a handle hingedly attached to said body unit, an exhaust outlet for said fan casing including telescoping arcuate tubular members attached respectively to the aoe'moa handle and to the fan casing, their longitudinal arcuate axes being concentric with the axis of swinging movement of thehandle, and a flexible, collapsible tubular covering enveloping the joint between said telescoping members, its respective ends sealed around the respective telescoping members.

6; In a vacuum cleaner, a body unit including a stationary fan casing, positioned in a ver-- tical plane and having its axis extending hort- -zontally and transversely, a handle pivoted to said body unit, and an exhaust outlet for said fan casing including telescoping arcuate tubular members attached respectively to the handle and to the fan casing, their longitudinal arcuate axes being concentric with the axis of swinging movement of the handle.

7. In a vacuum cleaner, a body unit including a stationary fan casing positioned in a vertical plane and having its'axis extending horizontally and transversely, a handle pivoted to said body unit on an axis parallel to that of the fan casing, and an exhaust outlet for said fan casing l including telescoping arcuate tubular members attached respectively to the handle and to the fan casing, their longitudinal arcuate axes being concentric with the axis of swinging movement of the handle, said outlet lying chiefly below the fan casing and in the plane thereof.
