' 'vAcUUMcLEANnn ATTACHMENT.

Application filed June 9,

This invention relates to improvements in vacuum cleaners, and has particular reference to cleaning attachments therefor.

Cleaning attachments usually provided as 5 accessories for vacuum cleaners are connected to the cleaner by means of a rigid handle member, one end of which is joined to the attachment while the other end of the handle is fitted into one end of a flexi- W ble tube, the opposite endof which is directly attached to the cleaner. These attachments, which usually comprise a number of nozzles, brushes and the like, permit dust and other matter to be collected from walls, curtains, furniture and like surfaces, but it has been found that, with attachments now in common usage, all surfaces are not easily accessible.

Some of the nozzle attachments furnished with vacuum cleaners are' provided with comparatively large mouths and when such a nozzle is applied toa curtain or other loose fabric there is a likelihood that said fabric will be drawn into the mouth of the nozzle and thereby interfere "with the operation of the cleaner. Also the attachments now used oftentimes will mar highly.

: so connect a cleaning attachment to a vac-' uum cleaner that said attachment may be adjusted to various positions with respect to the handle supporting the same so that places to be cleaned, which might otherwise can be easily reached with the attachment. 7

A further object is to provide a cleaner attachment capable of connection to all types of cleaners, and which is simple in construction, eflicient in operation, durable in use, and capable of beingmanufactured on a commercial'scale.

The above and other objects will appear more clearl from the following detail description, w en taken in connection with the accompanying drawings, which illustrate pieferred embodiments of the inventive 1 ea.

In the drawings- Figure 1 is a. perspective-view of a vac- 1926. Serial No. 114,595.

uum cleaner, showing an attachment connected thereto;

Figure 2 is an elevational view of a connection for an attachment indicating the latter in one of its adjusted positions;

Fi 'ure 3 is a similar view showing the attac ment in a different position;

Figure 4 is an enlarged sectional view through part of the connection for the attachment.

Referring more particularly to the accompanying drawing, the numeral 10 indicates conventionally a vacuum cleaner which may be of any well known type and to which is connected one end of a flexible tube '11 commonly used with such cleaners. The free end of the flexible tube 11 is joined to a handle member 12 which may be a rigid tube. On the outer end of the handle member there is mounted an elbow 13 which has a similar elbow 14 connected thereto and mounted for complete rotation relative to the first named elbow, as will be seen by reference to Figures 2 and 3.

The nozzle 15 has the free end of its neck fitted into the outer end of the elbow 14 and is also adapted for rotation about its longitudinal axis when disposed within said elbow. In order that the nozzle may be ,friction'ally retained in position the outer end of the elbow 14 is externally screw threaded to receive thereon the internally screw threaded coupling nut 16. This nut is provided with an inwardly directed flange 17 and interposed between said flange and the end of the elbow 14 there is mounted a gasket 18 which encircle s' and engages the outer wall of the neck of the nozzle. By threading the nut 16 upon the elbow the gasket, which is made of some resilient material such as rubber, will be compressed so as to be reduced in thickness. This cornpression of the gasket will cause the inner periphery thereof to more tightly engage the neck of the nozzle and will thus frictionally maintain said neck in any one of its adjusted positions.

The meeting ends of the elbows 13 and 14 are likewise connected by a coupling nut 20 threaded upon the elbow 14 and being of the same construction as the nut 16. The end of the elbow 13 adjacent the cou ling nut is provided with an out-turned ange 19 which is engaged by the flange of the j 1 nut 20 and in turn engages one of the surfaces of the gasket 20 interposed therebea tubular handle, an elbow having one end tween. The elbow 13 may be connected to mounted on the end of said handle and the the handle 12 by a coupling nut 21 similar other rotatably connected with one end of a 15 to the nut 16 and mounted in position in a second elbow, said second elbow carrying at 5 like manner. its other end a suction nozzle rotatably I The end of the handle member 12, which mounted therein, the ends of each of said is joined to the flexible tube 11', may also elbows being approximately at right angles be connected to said tube by means of a to each other. 20 coupling nut 22 similar to the other coun testlmony whereof I have affixed my 10 pling nuts described. g ure.

What is claimed is: a A vacuum cleaner attachment comprising DOMENICK TONSO.
