My invention relates to suction nozzles and more particularly to a suction nozzle of the duplex type.

ture, a large portion of the surface of the fabric is relatively fiat. However, there are areas which are sharply curved, as the arm of a chair. or divan,

and in addition ther are comersfand crevices where dirt is likely to collect. A suction nozzle which is provided with an elongated suction opening is useful for efliciently cleaning relatively fiat surfaces. However, curved or arched surfaces present the difficulty that a portion of the suction opening will be completely uncovered. and so permit a large amountof air to flow into the suction nozzle without contacting the Surface being cleaned. Also, difilculty is encountered when an attempt is made to clean a small corner or crevice, as one end only of the nozzle can be used to contact the surface being cleaned-and the effectiveness of the nozzle is reduced. Also, it is sometimes diflicult to insert the nozzle into the comer.

In cleaning furniture, such as overstuii'ed furni- The lips l6 and I1 are coplanar and form between them the suction opening I 2 which is relatively long in proportion to its width. The lips l8 and I1 seal the suction opening l2 tightly against a surface of a relatively flat material, and due to the length of the opening l2 permit ready and eflicient cleaning of a large area by covering a "considerable width of strip in one continuous In accordance with m invention, a duplex suction nozzle is provided with an elongated suction opening in one plane, which maybe used for efficiently cleaning relatively fiat surfaces, and a second suction opening formed in a different plan with a pointed end for ready insertion inconfined spaces. What I consider to be novel and my inventio may be better understood by reference to the following specification and appended. claims when considered in connection with the accom-.

panying drawings. in which I Fig. 1 is a top view of my improved nozzle Fig. 2 is a sectional view taken along the line- 2-: 0! Fig, 1;

Fig. 3 ha sectional view taken 2-2 of Fig. 2;

Fig. 4 is a sectional view similar along the line to Fis; o, with the nozzle in a different cleaning position; and

Fig. 5 is a front view ofthe nozzle taken from the left, as shown in Fig. 4, broken away in part to expose the parts beneath.

Referring to the drawings. It indicates a nozzle in a plane at right angles to the face I ,I. provided with afsmall suction opening it in a" pointed end .ing I2 isfbounded by a lip 11 r t-med in aplate I2- body having a cleaning face I l with an elongated suction opening l2, and a second cleaning face I! secured to body "by means of a pluralityof screws ll, shown in dotted lines in Fig. 2. 4

movement of the nozzle body across the surface. It may be found desirable in cleaning certain materials to use a brush 20,, which is secured within the suction opening l2 by two spring chps 2 I, whi;h extend over the lip I6 at spaced points.

, For connection of the nozzle body In to the vacuum cleaner, or other source of suction, a tubular socket member 22 is provided and pivotally connected to the body it on an axis parallel to the lengthwise extent of suction opening l2. Socket member 22 is provided with a cylindrical portion 23 which is received in a correspondingly shaped cavity. in nozzle body I0. Cylindrical portion 22 is provided with two end closure plates 25 and 26, which are in turnprovided with recesses 2'! and 2s respectively, and cut-out friction spring fingers 29 and 30. Spring fingers 29 and 30 serve to hold the body It and socket member 22 in any desired relative position, such as in the position of Fig. 2, or in the position of Fig. 4. Socket member 22 is secured in position in cavity 24 by means of plate It. Socket member 22 is provided with an opening I! which communicates with the suction opening l4 when in the position of Fig. 2, and communicates with the suction opening l2 when in the position of Fig. 4.

Suction opening I4 is provided with a forward lip 32 in the pointed end II of body It, as best indicated in Fig. 5. The lip 23 formed in plate ll extends transversely of the face l2, and forms a rear lip for the suction opening it. The area of the suction opening it formed between the lips 32 and 23 is relatively small. and'due to the shape of the end It may readily be inserted .in small crevices and confined spaces. In addition, the width of the suction opening I! is so relatively small that the lips 22 and II can simultaneously contact a surface of arched or curved shape. This permits ready and eflicient cleaning of such arched and curved surfaces, as are found on the top and arms .ofoverstuffed furniture.

With this duplex nozzle, furniture may be readily cleaned by positioning the nozzle body It on the socket member 22 in the position indicated in 4, with-or without the brush 2!.

When, the' nozzle is connected to a source of .suction, the air flows over the surface adjacent the face ii in contact with the suction opening 92 through the-opening ii to the vacuum cleaner. I When the large areas of the furniture have been cleaned and corners are reached which cannot be cleaned with the elongated suction opening l2, or it is desired to clean the arms or other curved surfaces, the nozzle may be positioned in its alternate position, as shown in Fig. 2. The small suction opening it and pointed end 55 can then be inserted in such corners, or in contact. with such curved surfaces. the surfaces being cleaned into the suction opening it and through the opening 3! to the vacuum cleaner connected to the nozzle.

From the foregoing, it may be seen that by the construction or my improved nozzle, fabric covered furniture may be readily and emciently cleaned with a single nozzle, using the elongated suction opening for cleaning large flat areas and using the pointed end with the small suction opening for cleaning in confined spaces and on curved or irregular surfaces.

What 1 claim is:

i. A duplex suction nozzle including a hollow body member, a flat face on said body member having an elongated suction opening, a second face on said body member extending at an angle to said first face having a dissimilar suction opening, a tubular handle socket pivotally connected to said body on an axis parallel to the lengthwise extent of said elongated suction open= ing, and friction means secured to said socket for holding said socket member in position relative to said body member in communication with one or the other of said suction openings.

The air then flows across aevaooe or the other of its selected positions.

3. A duplex suction nozzle including a hollow body member having an elongated flat contact surface in one plane and a flat surface in a plane at right angles thereto, a plate secured to said body member bounding an elongated suction opening in the elongated surface and a small suction opening in the other surface, a

socket member secured within said body member by said plate, said socket member pivotally se- 2. A duplex suction nozzle including a hollow I body member having an elongated face in one plane and a flat face in another plane, a plate secured to said body member bounding an elongated suction opening in. one face and a small her, and a cured to said body member and having an opening communicating in one position with one suction opening and in another position with the other suction opening, and resilient means secured to said socket member and engaging said body member to hold'said socket member in a selected position.

4. A suction nozzle including a body member having a central cylindrical cavity and an opening communicating therewith, a socket member having a tubular portion extending through the opening and a cylindrical portion seated in the cavity of said body member, caps secured to the ends of said cylindrical portion having struck out fingers frictionally engaging said body memplate secured to said body member for holding said socket member in position and defining with said body member an elongated suction opening in one plane and a dissimilar suction opening in another plane.
