VACUUM-CLEANER NOZZLE.

Specificatioers Patent. Patented July 25, 1916.,

Continuation in part of application Serial No. 859,952, filed September 3, 1914. This application filed October 26, 1915.

To all whom it may concern:

Be it known that I, AUGUST E. ROEV'ER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Vacuum- Cleaner Nozzles, of which the following is a specification.

This invention relates to vacuum cleaner nozzles, the object of the invention being to provide an improved nozzle thoroughly ef fective to take up threads and other debris of this general character and in which the thread-picking devices will be maintained in their proper thread-picking positions during the movement of the nozzle over the surface to be cleaned.

The object of the invention, therefore, is the provision of an improved nozzle efiective for the purpose stated, which is simple in construction, inexpensive to manufacture, and reliable and durable in use.

In the drawings accompanying and forming part of this specification, Figure 1 is a bottom view of one form of the nozzle having the present improvement applied thereto; Fig. 2 is a longitudinal sectional view taken in line 22, Fig. 1; Fig. 3 is a crosssectional view taken in line 3-3, Fig. 1; and

Fig. 4 isa side view of one of the thread-removing devices shown in the other figures.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

In the present instance only so much of a vacuum cleaner is shown as is necessary to illustrate the present improvement, and

therefore a part of the nozzle 2 of usual form is illustrated. This nozzle is provided with the usual elongated opening 3 of suitable length and width to permit the use of the improved thread-removing devices. Carried in the opening of this nozzle is a lengthwise-extending rod 4 projecting into openings 5 in the end walls of the nozzle, and located on this rod, which is pivotally supported for rocking movement, are a series of thread-removing devices 6, which are preferably fixedly secured to the rod, and these thread-removing devices rock with the rod according to the direction in which the nozzle is shifted over the floor. These thread-removing devices 6 are formed of some soft flexible or pliable material, and

Serial No. 57,911.

that found most efficient in use is rubber,

and each is made of a peculiar shape. Each comprises a member having a round underor teeth, and this member is provided with a. shank 7 preferably narrower at its-lower end than it is at its upper end, and this shank is provided with an opening 8 by means of which each of these rubber devices is mounted upon the rod. These devices are located at intervals along the rod and the curved floor portion thereof terminates in sharp flexible points 9 at each side of the shank, and in practice as the nozzle is shifted over the floor, for instance in a. forward direction, (see arrow in Fig. 3), these members are rocked with the rod. This action is shown in Fig. 3 in dotted lines, and as the nozzle is drawn backward these members are shifted forward so that the soft flexible points of the rubber quickly and readily pick up the threads and remove them from the floor, and this is materially assisted by reason of the character of material of which these thread-removing devices are made, since the threads will adhere to the rubber as the devices rock back and forth in the movement of the nozzle over the floor and are thus gathered and pulled off the floor so that the suction can draw them into the nozzle.

To maintain the thread-picking devices in their proper working positions, suitable means is provided. In the present instance this consists of a pair of projections 10, one located at each end of the rod, and so located in the present instance that they will engage the side walls of the casing and thus maintain the thread-picking devices in such position that their pointed ends will engage the face to be cleaned, see dotted lines in Fig. 3. Thus it will be observedthat these limiting stops 10 engage one wall of the casing, as the front wall thereof, when the nozzle is being pushed forward and the rear Wall thereof when the nozzle is pulled. backward, this change in position of the stops resulting from the rocking of the rod due to the movement of the thread-pickers over the surface being cleaned, and that in each of these positions the thread-pickers are maintained in such position that their pointed or toothed ends are in position to effectively pick up threads and other lint of similar kind as the nozzle passes back and forward over the surface being cleaned, so that there is no tendency of such threadpicking up devices to move out of their nor mal working position. Within the purview of my invention is any form of means which will limit the rocking movement of the thread-picking devices on the rock shaft carrying the same.

It will be "observed that in the operation of this improvement, while one set of teeth are in position to remove threads and other lint from the surface being cleaned the opposite set of teeth have been carried into posi tion where they are in raised position, so that they are subjected to the air stream, whereby any adhering material thereon is readily removed and drawn into the nozzle.

It will be understood that the various details may be more or less modified without departing from the spirit and scope of this invention.

I claim as my invention:

1. A cleaner nozzle having a lengthwise extending opening therein, and a plurality of thread-removing members suspended within said nozzle and each having a tapered portion extending transversely of such opening.

2. A cleaner nozzle having a lengthwise extending opening therein, and a plurality of rocking members spaced apart within 'said nozzle and each comprising a depending body portion provided at its lower end with thread-removing projecting portions and means'for suspending said members to permit the rocking thereof during the operation of the nozzle.

3. A cleaner nozzle having a lengthwise extending opening therein, a rod extending lengthwise thereof, and a plurality of flexible rocking thread removing members mounted upon said rod and spaced apart within said nozzle and each comprising a depending body portion provided at its lower end with oppositely extending proecting portions. .9 I

4. A cleaner nozzleshaving a lengthwise extending opening therein, a plurality of rocking flexible thread-removing members suspended within said nozzle and each comprlsing a depending body portion having oppositely tapered portions, and means extending transversely through said flexible members for suspending the same for rocking movement during the operation of the nozzle.

5. A cleaner nozzle having an opening therein, rocking means suspended within said opening for rocking movement during the operation of the nozzle and having along said openmg thread-removing pointed-end projections extending transversely to such openmg.

6. A cleaner nozzle having an opening therein, rocking means pivotally supported upon said rod and having their under surfaces in the plane of said work-engaging surface.

9. A cleaner nozzle having an opening surrounded by a work-engaging surface, a rod located in said opening, and a series of flat flexible thread-removing rocking devices carried upon said rod and having their under surfaces in the plane of said work-engaging surface. 1

10. A cleaner nozzle having an opening surrounded by a work-engaging surface, a rocking rodlocated lengthwise within said opening, a series of flexible rocking members fixedly carried on said rod within said open.- ing and each having a curved under surface located in the plane of said work-engaging surface and terminating in oppositely lo-' cated points.

11. A cleaner nozzle having an opening 7 therein, and a series of rocking members pivotally supported within said opening and spaced apart, each of said rocking members comprising a flat body portion having an edgewise extending pointed portion normally projecting transversely of the nozzle.

12. In a vacuum cleaner nozzle of the type having an elongated inlet mouth surrounded hy work-engaging jaws, an agitating device pivoted in said casing upon an axis parallel with said mouth, said device comprising a plurality of radial members having flexible teeth projecting substantially tangentially of the circle drawn about the pivot axis and arranged to engage and comb the surface operated upon, and means for rotating said device about its pivot so as to raise said teeth from such surface and present them to the air stream.

13. A cleaner nozzle having an opening therein, rocking devices pivotally supported within said opening, said rocking devices comprising a' plurality of flat, toothed members, means operative upon changes in the direction of movement of the cleaner for rocking said devices to elevate certain teeth and depress other teeth, and stop means 130 to arrest such rocking movement and hold the depressed teeth in engagement with the work surface.
