3 Claims.

Our inventionrelates to a new and improved vacuum cleaner attachment.

One of the objects of our invention is to pro vide an improved vacuum cleaner attachment of 6 the type shown in U. S. Patent No. 1,729,103.

Another object of our invention is to provide a vacuum cleaner attachment which shall provide a collecting bag of large size.

Another object of our invention is to provide a collecting bag which can be conveniently coupled to a vacuum cleaner.

Other objects of our invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it bethe same and not to limit it in any manner.

'I'heattachment is intended to be applied to any vacuum cleaner I having an .outlet nozzle 2 and a handle 3. A cloth bag 4 of any suitable type may be provided with an ear 8, by means of which it can be connected to the handle 3 by a member i The bag is adapted to be opened. Normally however, its upper edge is folded over, as Fig. 9 shows, and is inserted into a- U-shaped clamp ll, secured by button head bolts l8 and screws is, similar to the closing device shown in former Patent No. 1,729,103. This feature however may be varied in any convenient way, for instance Fig. 6 indicates-the way of closing the bag openblouse fronts, shoes etc. which device howeverv forms no specific part claimed for this invention,

ing understood that the above general statement of our invention is intended to generally explain ing by means of two series ofinterlocking chain and is therefore not especially detailed. This bag 4 is provided with an inner hose 5, which communicates with a coupling 1. This coupling 1 can be connected to the outlet nozzle 2 of the vacuum cleaner so that the air current which is forced out of said nozzle 2 is also forced through the hose 5. The hose 5 may be made ofany suit able fabric provided with any suitable lining. The hose 5 is preferably permeable to air although it may be made substantially impervious to air if desired. If the hose 5 is made permeable to air, the interior thereof is made sufliciently smooth, and the hose 5 is made suiflciently narrowso that the current of air and dust passes through the hose 5 without depositing the dust on the walls thereof. We have found it suitable to make the hose 5 2% inches in diameter and to make it of rubber or the like having a lining made of rubber or the like. The bag 8 is made of suitable paper, which is preferably permeable to air. It is provided with a mouth member 9 which can be made of cardboard or other material having sufllcient stiffness to enable the mouth of the bag to be readily connected to the coupling provided at the upper end of the hose 5. However, this mouth member 8 may be readily, collapsed into flat form, so that the bag 8 may be shipped or stored in flat form. The operation of this device is substantially the same as that shown in our previous device illustrated in U. 3. Patent No. 1,729,103. The current of air. and dust passes through the hose 5 with considerable velocity so that substantially all the dust is projected into the bag 8. If some of the air escapes in the hose 5, this does not cause dust to be deposited to any injurious extent upon the inner wall of the hose 1 5 for the reasons before specified. The air current leaks out of the pervious paper bag as it passes through the top portion thereof, at which portion the air current changes in direction. to enter the lower part of the bag. The air current passes out of the bag, leaving the dust and dirt deposited therein. By making the hose 5 at the top of the paper bag sufllciently permeable to air, enough air can leak out of the same to prevent the paper bag from bursting. This makes it unnecessary to support the walls of the paper bag 8 by the wall of the cloth bag 4, so that, as shown in Fig. 1, there is a substantial space between the paper bag 8 and the inner wall of the cloth bag 4. The only purpose for using the cloth bag 4 is to prevent the paper bag 8 from being accidentally torn or otherwise injured.

- In the embodiment shown in Figs. 3 and 4, the paper bag 8a is also made of permeable paper,

2 and, it is provided with a mouth l5 having a stiffening member 9a. The paper bag may be made of two or more pieces suitably connectedin any manner as by stitching or the like; The cloth bag 4 may be a side-opening bag of the well kncwn' type so that the paper collecting bag may be readily inserted and connected to the coupling member located at the top cf the hose 5,

It will-be noted that the coupling member I which cooperates with the lower end of the hose 5, projects. from the outer protective bag 4.

. Hence, thebag can be coupled to the outlet nozzlein the ordinary manner.

One of the features of our invention is that the hose 5 is suiiicientlynarrow tc cause the air current to pass through the same with high velocity, 50 that the, dust swept along instead or being deposited upon the inner wall of the hose to clog the pores thereof.

The hose 5 could be made of impermeable ma- .terial, such as rubber-lined fabric, up to or nearly up-to the coupling member which connects the same to the permeable bag 8.- This increases the velocity with which the dirt passes through the hose 5, so that it is carried around the upper bent portion of the bag E. This feature ticularly useful where the vacuum cleaner has low suction power, The coupling shown in Figs.

' 6-8 comprises an outer metal collar ll, having p-letely eliminate leakage of air. The outer an inner metal collar l spaced therefrom. The mouth 9 of the bag 8 fits snugly between the collars II! and II, so asto substantially or com-.

collar II is provided with a clamp l3 hingedly connected thereto at I 4. The clamp I3 is forced to the operative position by means 01 a blade' spring iii. The clamp I3 is provided with a point or points ['2 which extend through a. suitable opening in the outer collar ll, so that the point or points l2 can penetrate the-mouth of the bag 8 and hold the same firmly but releasably in position.

Wehave shown a preferred embodiment of our invention, but it is clear that numerous changes and omissions cculd be made without departing from the spirit of our invention.
