Patented Sept. 8, 1942 SUCTION NOZZLE Gustav Axel Peterson,

to Electrolux Corpora corporation of Delaw Stamford, Conn., assignor tion, New York, N. Y., a are Application January 12, 1940,'Serial No. 313,491 Claims. (01. -155) My invention relates to suction nozzles, and more particularly to suction nozzles of the duplex type.

An object of my invention is to provide an improved duplex suction nozzle.

A further object of my invention is to provide a duplex suction nozzle in which the change from the use of one of the nozzles to the other may readily be made.

A still further object of my invention is .to provide a duplex suction nozzle of simple construction which may be readily'assembled.

What I consider to be novel and my invention .may be better understood by reference to the following specification and appended claims when considered in connection with the accompanying drawings, in which:

Fig. 1 is a side view of a vacuum cleaner connected to my improved nozzle;

Fig. 2 is a front view of the nozzle partly in section;

Fig. 3 is an enlarged bottom view of nozzle;

Fig. 4 is a cross-sectional view of the nozzle in one position;

Fig. 5 is a similar cross-sectional view in which the nozzle is in a difierent position; and

Fig. 6 is a crossfisectional view taken along the line 6-6 of Fig. 4.

Referring to the drawing, l0 indicates a vacuum cleaner of the inside-bag type, which is conpart of the nected to my improved nozzle H, by means of a flexible hose I2, and a rigid handle member l3. In the cleaning of a rug, or the like, with nozzle l I, the embedded dirt is removed by an elongated suction opening M. The suction opening I4 is provided with a smooth lip l5. For cleaning surface litter, an auxiliary suction opening I8 is provided, which is smaller in width and shorter in length than the suction opening M. The suction opening I4 is provided in a main nozzle body H, which is pivotally connected by means of two screws l8 (as best indicated in Fig. 6), to an intermediate block or secondary nozzle member IS in which the auxiliary suction opening H5 is provided.

For connecting the nozzle II to the handle member l3, a tubular swivel elbow 20 is provided and connected to the secondary nozzle Elbow 20 is secured to the block l9 by means of a resilient split. ring 2i. Elbow 20 is rotatable with respect to the nozzle body ll on an axis perpendicular to the lengthwise extent of the suction opening l4 and body l1. Elbow 20 communicates with the interior of secondary nozzle member l9 and through a passage 22 in secondary nozzle member IS with the suction opening M. The elbow 20 also communicates with the auxiliary suction opening it provided in the nozzle member l9.

When the suction opening I4 is in normal position, as shown in Fig. 4, a plate 23 carried thereby covers the auxiliary suction opening l6 and provides a gliding surface 24, positioned behind the suction opening l4 and tangent to the plane of the lip IS. The gliding surface 24 in cooperation withthe lip l5 insures a smooth movement of nozzle ll over the rug surface. The main nozzle body I! is adapted to move on the axis of screws 18 relative to the nozzle member l9, and so readily accommodates itself to variations in the.

surface being cleaned. The handle member 13 also may be rotated on the, swivel elbow 20 to insert the nozzle below a low piece of furniture.

When it is desired to remove surface litter, the nozzle H is lifted from the rug and by a quick downward movement, the nozzle body I! may be pivoted on the axis of the screws l8, to the position indicated in Fig. 5. The nozzle body I! is locked in this position by means of,'a spring plate 25, with a projection 26, which is seated in a recess 21 provided'in the nozzle member l9. In

this position, the plate 23 uncovers the auxiliary suction opening 16, which is smaller in length and thickness than the main suction opening M. Suction opening I 6 extends parallel to suction opening M, the length of nozzle member H between adjacent walls 28 of nozzle body ll. The forward lip of suction opening l6 formed by the rear edge of the plate 23 is spaced above the rear lip on the gliding surface 29 provided in the nozzle member H]. In this position, the plate 23 covers the passa e 22 in the nozzle member l9. When the surface litter has been removed, the nozzle body I! may be returned to its normal position by pressure applied to the top of it, or simply by a quick movement in a reverse direction as the spring tension in'plate 25 is small enough not to greatly resist such movement.

small suction opening in one position and the passage in saidnozzle member in another position; and a second plate carried by said main nozzle body having a projection adapted to engage a re-' cess in said nozzle member to hold said main 'nozzle body in an inoperative position and uncovering the small suction opening at the end 01 said secondary nozzle member for presentation to a surface being cleaned.

2. A suction cleaning tool including a secondary nozzle having a small suction opening and an inlet passage and an outlet, a main nozzle having an elongated suction opening and communicating with the inlet passage in said secondary nozzle in normal position, said main nozzle being pivotally connected to said secondary nozzle on a transverse horizontal axis parallel to the lengthwise extent of the elongated suction opening, closure means carried by said main nozzle covering said small suction opening in said secondary nozzle in normal position of said main nozzle, and latching means adapted to hold said main nozzle in inoperative position with said closure means covering said outlet passage and uncovering the small suction opening in said secondary nozzle.

3. A suction cleaning tool including a main nozzle having an elongated suction opening, a

' second nozzle pivotally connected to said main nozzle on a transverse horizontaLaxis parallel to the lengthwise extent of said main nozzle, said second nozzle having a small suction opening removed ilrcm the main nozzle and adapted to be opened to the atmosphere, said small suction opening being adapted to be placed in contact with the surface to be cleaned when said main nozzle is in inoperative position, a passage in said second nozzle adapted to communicate with the interior of said main nozzle, closure means carried by said main nozzle adapted to cover said 4. A suction cleaning tool including a main nozzle-shaving an elongated suction opening and an outlet port, a second n'omle having an inlet passage communicating with the interior of said main nozzle and having a small suction opening and an outlet e, securing means pivotally connecting said main nozzle to said second nozzle on a transverse horizontal axis parallel to the lengthwise extent ot said main nozzle, means carried by said main nozzle covering the small suction opening in theoperative position or the main male an the inlet passage or said second nozzle in the inoperative position of the main small opening in one position and said passage in said second nozzle in a other position.

nozzle and resilient means carried ,by said main nozzleadapted to engage said second nozzle to hold said main nozzle in the inoperative position upon movement of the main nozzle with respect to the second nozzle on the axis of said securing means, said small suction opening being uncovered to place the second nozzle in operative condition when the main nozzle is in the inoperative position.

5. A suction cleaning tool including a main nozzle having an elongated suction opening, a second, nozzle having a passage communicating with the interior of said main nozzle and a small suction opening and an outlet port, securing means pivotally connecting said main nozzle to said s cond nozzle on a transverse horizontal axis parallel to the lengthwise extent of said main nozzle, means carried by said main nozzlecovering the small suction opening in one position of said main nozzleand the passage'ot said second nozzle in another position, and'an elbow tube secured at one end to a vertical face of said second nozzle, the other end of said elbow being adapted to be connected to a suction tube which makes an acute angle with the surface being cleaned when the cleaning tool is in use and which lies entirely in a space on the side of said vertical face opposite. to that occupied by said main nozzle,-said main nozzle being adapted to occupy a large part of the space immediately over the GUSTAV PETERSON.
