3 Claims.

The invention-relatesto a novel arrangement of carrying a dust collecting receptacle on a portable vacuum cleaner unit and of delivering the dust to such receptacle from, the-pumping device.

An object of the invention is to provide means particularly designed for use on the ordinary portable household vacuum cleaner, which will permit the delivery of dust from the pump to the collecting bag, without the necessity of forcing the dust through all the dirt already collected in the bag, whereby the high back pressure or resistof the particles in the bag caused by such operation, with the resultant impairment of the suction of the pump and the penetration and escape of the smaller dust particles through the walls of the bag, will be substantially entirely eliminated.

Another object of the invention is to provide arrangement of the character described which may be readily applied to existing types of portable cleaners. Y

A further object of the invention is to design the parts so that the appearance and utility of the cleaner when equipped with my arrangement will be substantially the same as cleaners now on the market;

A still further object is toprovide an arrangement of the character described in which the conduit for delivering the dust to the bag may be incorporated as a part of the cleaner handle.

The invention possesses other objects and features of advantage. some of which, with the foregoing. will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and descriptlon maybe adopted within the scope of vention as set .forth in the claims.

Referring to said drawing: Figure 1 is a front view of a portable vacuum the incleaner designed in accordance withmyinvention.

Figure 2 is a side view of the cleaner shown in Figure L with parts broken away and shown in. section.

As illustrated in the drawing, the arrangement of my invention s designed to be incorporatedtion 9 of the pump is preferably disposed adjacent a side edge thereof.

Arranged to be supported, as shown in Figure 1, by thehandle 22 which is pivotally connected to the unit 5, is a receptacle orbag 13 into which 0 the dust or dirt particles drawn through the pump are arranged to be deposited and collected. The bag, as is customary, is constructed of a porous material so that the air which is drawn through the pump with the dirt may readily escape through the walls of the bag while the dirt particles are retained within the bag. In the bags of this type as previously constructed, the open or intake end was disposed at the bottom and connected thereat directly tothe outlet of the pump. With the intake thus located at the bottom of the bag the air and dirt entering the bag had to pass through all the dirt previously collected therein and settled over the intake. In this manner the contents of the bag during the operation of the cleaner were maintained in I a high state of agitation and at the same time offered considerable resistance to the admission of the air and dust to the bag as well as the free discharge of the air through the bag walls. In 86 .accordance, however," with invention the intaketothebagisatthetopsothattheairand dust entering the bag does not necessarily disturb the previously admitted dirt which has settledto the bottomor closed end of the bag. and therefore no agitation of the dirt and impediment to the free flowof air and dust to the bag is caused. With my arrangement as shown in Figures 1 and 2, the outlet connection 9 of the pump is connected by meansof aflexible conduit 24 9o with'a conduit-21 which is formed as a part of thehandle 22 of the cleaner. Areturn bend 26 formed as an extension of theconduit 21 at the top thereof provides for connection of the conduit tothetop ofthebagandisarrangedtoinsurea free flow of air from the conduit to the bag. Preferably the attachment between the bag and bend issuchas to permit the ready removal or replacement of the bag when it is desired to empty the bag of the dirt collected therein. Asnap fastener 11m 18 or the like maybe used for attaching the lower end of the bag to ,the wit or handle. Preferably theconduits 21 and Mas well-as thereturn bend 26 is formed of anon-porous material so that the air willbe prevented from through the walls thereof and the dust entrained before reach ingthebag. Itwillbeunderstoodthatthe conduit 24, as well as the bag, is flexible so that the former will not interfere with the free movement of the handle.

e no

It will now be clear that the means of my invention is well adapted to the accomplishment of the objects hereinbefore referred to.

I claim:

1. In a vacuum cleaner of the character described, a portable pump unit provided with a dust outlet, a handle pivotally carried by said unit for propelling and guiding same, a portion of said handle intermediate the ends thereof being of tubular cross section, a flexible conduit connecting the lower end of said portion to said outlet, the upper end of said portion being outwardly and downwardly curved from the axis of said handle, and a dust receiving bag removably secured at its upper end to the upper end of said portion and being detachably secured at its lower end to said unit.

2. A cleaner comprising, a pump unit provided with a dust outlet, a handle pivotally mounted on said unit for moving and positioning same, a portion of said handle intermediate the ends thereof being of tubular construction, aflexible conduit connecting said portion to said outlet, and a dust receiving bag secured to said portion.

3. A cleaner of the character described comprising, a pump unit provided with a dust outlet, a handle pivotally mounted on said unit for moving and positioning same and being formed over a portion of the length thereof to provide a conduit, means for flexibly connecting one end of said conduit to said dust outlet, and a dust receiving bag connected to the other end of said conduit.

EDWARD J. THOR.
