56 Claims. (Cl. 15--:%57l) This "invention relates to a new and useful improvement in wheeled conveyances and more particularly to a cart for supporting vacuum cleaners attachments therefor.

"There are new on the market certain vacuum cleaners which are made to slide on the floor or to he carried by a handle. 'Wh-en slid on the floor the 'useable length of the hose is shortened as the cleaning attachment is usually carried waist high. This invention comprehends furrushing a peculiar form of cart for supporting the vacuum cleaner unit of the type above dcscribod which permits free use of the vacuum cleaner attachments and at the same time permite the use-oi both hands for manipulation thereof.

The invention com-prises 'certa -in novel combination and arrangements of parts as *will hereinafter more fully set forth in the claims. In the accompanying drawing, there has been illustratcd one complete example or an embodiment of the invention, but it is to be understood it is present-ed for illustrative purposes only and is not :to be accorded any interpretation such as might have effect ol limiting What is claimed as the invention short of its true and -comprehen-- sive scope in the art.

Figure 1 is a perspective view of the improved vacuum cleaner cart;

Figure 2 is a view of a spreader bar to be used in connection with the cart;

- Figure 3 is a top plan view of the vacuum cleaner earl, base;

Figure e is a sectional view taken along lines 5-4 ofFigure 3; and

Figure 5 is a view of astairguide.

.Referring .to the drawings in detail, lthe wacuum cleaner cart generally indicated .as alt 1x0 comprises a handle member i2 substantially U- shaped in vform with the upper part M curved or inclined outwardly from the base so that the cart can rest onthe wheels '30 and the upper part of thehandle Hi. When the hart is in this-lpfijsin the cleaner supported *by the cart "will extend in a. substantially horizontal position. The ends of the handle l2 pass through openings in one end of the stair guide members 26 and then the ends of the handle are removably secured in openings l6 and H? in the base 34. The openings l 6 and I8 are located in the base 34 adjacent 20 are positioned so as to hold the member 22 in the "proper position. The spreader 20 consists of We parts which are normally urged apart by suitable means such as spring M. "The ends of the bar 28 fit into openings in the handle 12. On the member 22 is secured vacuum support band 24 and attachment pockets at. lhere may be as many pockets as desired and some or the pockets may he placed on the back side of member '22. he make it comparativcly easy 'to take the cart up and down steps there is provided stair guides 2:8. The guides are at one end mounted on lower spreader bar 20. The other of the can guides are mounted on the base and are operatively held in place by the lower ends :of handle 42 passing into the base. The stair guides are the form shown in Figure 5 and are spaced adfiacen t the "wheels 30.

The supporting wheels 3-0 are mounted on a suitable axle 32 and the axle mounted and eds scent the rear end of the base 84. The wheels EH3 are so :iormed that the means for securing the wheels on the axle are so positioned that chey can-not strike furniture or other o'biiects. may .be accomplished as shown Figure *1 where the axle 32 does not extend outwardly 'as fares theouter edges of the rubber tires mounted on the wheels 36 and the whee-ls may be dished inwzsrd lyras in Figure 1.

The base 3b is supported at the rear by wheels 3i? :and the front end is supported 'by means The Grant support means may take various forms but spaced-apart l'egs work very satisfactorily. Part of the top surface is depressed and resilient pads 3$ are secured in the depressed portions. The end of a tank or pot type vacuum cleaner rests on the pads '36. Between the sections Carrying the pads es is a channel which has the iiorward part 38 lower than "the rim of the base 34. i l-1e rear porillon of the channel slopes at 12 toward the bottom of the channel. Located between the forward end and the rear portion of the-channel "is raised portion fill. 'Thearrangement or the channel "permits the electrical plug to be connected to the cleaner Without movin the cleaner "from the cart, and improves the flow of air to and from the vacuum cleaner. The channel feature is of extreme importance in the combination. The channel extends substantially across the base from front to back. When a vacuum cleaner is secured on the base the air going to and from the cleaner passes through the channel. A vacuum cleaner will not function properly without an ample supply of air so a cart for supporting a. vacuum cleaner while the cleaner is being used must be so constructed utilized, but if such an opening is used the necessary air for supplying the cleaner disturbs the dust on the floor. The channel formed in the support surface must be of sufficient width to receive the nose end of the vacuum cleaner and hold it out of contact with the bottom of the channel.

vacuum cleaner passes is in a different plane than the major portion of the support surface.

From the foregoing, taken in connection with the drawings, it will be apparent that there has been provided a wheeled cart that may be manipulated with facility when storing a vacuum cleaner'and attachments as well as supporting the attachments that are not being used while the cleaning is in progress.

This is an improvement over my co-pending application, Serial No. 23,049, filed April 24, 1948 now Patent No. 2,636,207.

What is claimed:

1. A vacuum cleaner cart comprising a base member with the rim of the top surface in a plane above the remainder of the top surface, a handle secured to and adjacent the rear portion of the base, pads secured to the base inside the rim, a channel in the base extending between the pads, and a raised member in the channel and spaced apart from the ends of the channel.

2. A device of the class described comprising a base having a rear and a front edge, an axle mounted adjacent the rear edge of the base, wheels mounted on the axle, means on the front edge for supporting the base in a substantial horizontal plane, a substantially U-shaped handle connected to the base and extending upwardly therefrom, removably attached bars attached to the handle, curved stair guides having one end secured to one of the said bars and the other end operatively mounted on the base, and a channel extending substantially across the base.

3. A vacuum cleaner cart including a wheeled support base, a portion of the base surface being depressed below the remainder of the base surface, and adapted to seat one end of a tank or pot-type vacuum cleaner, said depressed portion of the base surface having an air flow channel formed therein below the surface thereof and extending substantially across the base, Whereby air supplied from a vacuum cleaner supported on the base passes through the channel, below the depressed base surface, said channel having upwardly sloping ends deflecting the air upwardly, a handle means extending upwardly from the base with one end inclined outwardly therefrom, and stair guide means mounted on the base by the handle means at one end, and attached to the handle means at the other end.

The depressed portion of channel through which the necessary air supply for the 4.
