May 23, 1944. w. N. PATTERSON AIR CLEANING DEVICE Filed Dec. 5. 1940 INVENTOR. WWI/mm V. 1%v7ers0n Patented May 23, 1944 sr'rss PATENT FFEQE This invention relates to air cleaning devices and has. particularly to do with that type of device which cleans by drawing air through a nozzle.

In many cases it is desirable to have a tool which will pick up water from moistened fabrics which are being cleaned. The rd cleaner nozzle will not function to perform this work since in most cases the aperture is too large and it is necessary to keep the aperture closed by the materials being cleaned in order to get the proper cleaning action.

The present invention relates to a device for attachment to the standard type of narrow elongated nozzle which will render it useful in picking up water and soap suds or other cleaning mixtures from moistened fabrics.

An object of the invention is to provide a removable member for attachment to such a nozzle which member is so designed as to pick up the water or suds from the moistened fabric to be cleaned and positioned such that it will be removed by air passing into the nozzle.

other obdects and features of the invention will be found in the following description and claims.

In the drawing:

Fig. 1 is a perspective view of the cleaner nozzle with the attached element.

Figs. 2 and 3 show the parts in separated relation.

Fig. 4 is a plan view of the attachment device.

Fig. 5 is a view of the working surface of the attachment device.

Fig. 6 is a side elevation of the device as shown in Fig. 1.

Fig. '7 is a section through the tool.

Referring to the drawing, the air cleaning nozzle is shown at It and is of the type having a narrow elongated opening ll, see Fig. 7. A small lip I2 is formed around the opening. The means for producing a suction at the nozzle may be either an induction device operating on compressed air as described in detail in Patterson Patent No. 2,183,150 issued December 12, 1939, or the regular type of suction fan. The attachment for the nozzle which is to be used in picking up water consists of a blade-like member 15 having at its lower edge a curved portion It as shown particularly in'Flg. 7. The ends of the 50 blade are curved around as at H. Behind the blade a parallel wall It is formed integral at its base with the base of the blade. This wall I8 serves to clamp the blade on a wall 20 of nozzle Ill. Other clamping means can be used, if desired.

In the operation of the device the blade I! is rojected into the opening of the nozzle and the wall l8 holds it in place. A forward edge II of blade 15 is then arranged to be pressed into the moistened fabric 22 so that water, shown at 23, is squeezed therefrom. Air entering the nozzle then picks up the waterand removes it from the fabric. The device is usually drawn toward the user, as shown by the arrow in Fig. 7 and by repeated application practically all the moisture in a particular piece of fabric may be removed.

As will be seen, especially in Fig. 7, the attachment is so designed with respect to the tool that the suds or water that picks up behind the edge ii of the blade will, in addition to the nap of the cloth, practically fill the effective aperture of the nozzle and be drawn through the machine.

I claim:

1. In an air cleaning device, such as a vacuum cleaner or the like, a nozzle having a narrow elongated intake opening, and a one-piece attachment for said nozzle to render the same suitable for removing water from fabric which comprises a. blade of rigid material having a portion arranged to be received by one wall of said nozzle, and a portion to project outwardly from said nozzle, the edge and ends of said portion being curved in the direction of but below the other wall of said nozzle whereby to collect water from said fabric and position the same for removal through said nozzle.

2. In an air cleaning device, such as a vacuum cleaner or the like, a nozzle having a narrow elongated intake opening, and a one-piece-attachnient clip for said nozzle to render the same suitable for removing water from fabric which comprises a blade of rigid material having a portion to be received by said nozzle adiacent one wall thereof, a portion to project outwardly from said nozzle, the edge and ends of saidportion being curved in the direction of the other wall of said nozzle whereby to collect water from said fabric and position the same for removal through said nozzle, and means for removably fastening said blade in the position indicated.

3. In an air cleaning device. such as a vacuum cleaner or the like, a nozzle having a narrow intake opening, and a one-piece attachment for said nozzle to render the same suitable for recleaned.
