'3 Claims.

The present invention relates to portable vacuum cleaners of the type having a horizontally arranged motor.

The object of our invention is to provide an improved construction and arrangement in vacuum cleaners of this type, and for a consideration of what we believe novel and our invention, attention is directed to the following description and the claims appended thereto.

In the drawing,'Fig. 1 is a sectional elevation of a vacuum cleaner embodying our invention;

Fig. 2 is an exploded view of the base element'of the vacuum cleaner; and Fig. 3 is a perspective view of the resilient support for the front end of the motor.

Referring to the drawing, there is shown a vacuum cleaner in which the parts are arranged on a base element comprising upper and lower castings I and 2. The lower casting 2, which part of the base element, has a skirt 3 on which is pivoted a handle fork 4 and has a horizontal web 5 within the skirt on the under side of rear supporting wheels 6 and 1.

The motor s resiliently supported in the seat H bya. rubber ring l6 Having an irregular opening I! snugly receiving a boss 18 at the front of the motor and having ribs l9 defining a groove receiving the The ring I6 is clamped in the seat II by the upper casting I. While the rubber ring l3 serves solely as a resilient support for the motor, the rubber ring it in addition serves as an air tight seal between the motor and the wall 9 which is the rear wall of the fan casing. The motorlh'as a shaft 20 extending through an inlet opening 2| in the front wall 2 la of the fan easing into a suction chamber which terminates in a suction nozzle 22 having a rotary agitating element 23 driven by a belt 24 from the extended end of the motor shaft. Opposite the end of the shaft extension is a suction opening 25 in the front wall of the suction chem ing seats l0 and II electric motor I2.

ported in the seat rounding a boss I her which is normally closed by a suction plate 26.. Upon removal of the suction plate 26 and the belt 24, a suction hose may be connected to the fan inlet through a converter tool inserted suction opening 25 into sealing engagement with the fan'inlet 2| in a manner well Dust-laden air isdrawn which are mounted front and On the upper into the fan inlet 2| by a fan 21 fixedtothe mo tor shaft and is discharged through an outlet conduit 28 integral with the casting- 2 which may be connected to the conventional bag. The top casting l of the base element comprises a hollow section 29 which serves as the, top of the fan casing and a tongue 30 which fits in and closes a slot 3| in a wall 32 on the casting 2 which serves as the top wall of the suction chamber. Upon removal of the top casting the motor and fan may be lifted out as a unit from the lower casting 2. The slot 3| serves'as a passageway for the motor shaft extension.

The upper and lower base castings I and 2 and the parts heretofore described constitute a complete operative vacuum cleaner. The manufacture and assembly is simplified by the fact that all of the operative parts are mounted on the lower casting,

The upper-side of thevacuum cleaner is em. I closed by a hood 33 secured to the lower eastcleaner, serve as reenforcing walls for the lower casting 2 of the base element. As shown in Fig.

1, the hood-is spaced above the wall 32 which serves as a shelf supporting an electric light 36 indicated in dotted lines in Fig. 1. A projecting lip 31 on the hood provides a slot through which v the light shines to illuminate the surface in front of the nozzle.

It will be'noted that the hood does not support any of the operating parts of the cleaner and that it is protected from impact by the skirt 3, by the wall 35 and by the nozzle. The hood accordingly can be made of a material having low strength and resistance to shock such as a molded plastic.

What we claim as new and desire to secure by Letters Patent of the United States is:

1. A vacuum cleaner having'a base element comprising a suction chamber, a fan chamber, and a cradle for a horizontal motor in the order named from front to rear, a motor on said cradle having a fan on extension in the suction chamber for operating an agitating element, the top wall of the suction chamber providing a shelf for an electric its shaft and having a shaft- .viding a light-transmitting passag her hood ontheba'se element covering saidsheli and the motor and the tan chamber, said hood proeway directed toward thesuriace in front or the suction cham- 2. A vacuum cleaner having a base element comprising a suction chambena fan chamber, and a cradle for a horizontal motor in the order named from front to rear; a motor on said cradle havingai'anonitsshattandhavingas'hait extension in the suction chamber for operating an agitating element, said cradle including a shirt on said base element depending aroundthe motor and awe extending across the skirt beneath the motor, said skirt having vertical .walls or U-shaped contour withthe base of the- U at the rear of themotor and the arms oi the U on opposite sides of the motor with the ends thereof blending into the fan casing, means within the skirt for fastening the motor to the cradle, and a un tary hood enclosing said iastening means and the top or the motor and of the tan suction chambers, the lower edge 0! said hood 4 being adjacent the upper edge of said skirt and the side walls of the hood forming a continuation of the skirt.

3. A vacuum cleaner having a base element comprising a suction chamber having top and side walls of a suction nomle at its lower end, a tan chamber, and a cradle for a horizontal motor in the order named from front to rear, said I a continuation of the skirtiand a hood for the motor and the Ian and suction chambers, the

lower edge of the hood being adjacent the upper walla.
