' 2Claims. (01115 373) This invention relates to nozzles for vacuum cleaners and is particularly concerned with nozzles designed for use onrugs and similar pile fabric. In the normal cleaning of rugs and similar material it is usually adequate to subject the surface to suction applied to a relatively long suction opening. However, quite frequently localized areas of the rug may not properly respond to such suction, and it is therefore frequently desirable to subject such areas to a far more intense form of suction and it is also frequently desirable to subject certain areas to agitation as by the application of a comb or like agitating member during the application of suction so as to dislodge hairs and textile foreign matter which may have become enmeshed with the pile of In order to provide-a single instrumentality which can be used for subjecting the rug to the normal suction and which may also be used to apply intense suction tothe restricted area, sucsurface and in some of such devices manualvalve i manipulation by the operator is required. Furthermore; the provision'of suction openings on opposite sides of the nozzle necessitated intricate and large nozzle structures. 'It has long been the desire of workers in the vacuum cleaner art to avoid such structural and manipulatorydisadvantages while providing a nozzle which could be selectively used to apply a wide' swath ofqsuction or a more restricted and more intense suction and to simultaneously apply with. the intense suction a comb or like agitating device for detaching enmeshed foreign matter. i

In general terms, it is among theobjectsof the present invention to provide a nozzle which overcomes the above outlined objections. a 3

More specifically it is among the-objects of-the present invention to provide anozzle having a single body opening to which suction may bese lectively applied either to a large area of the opening or to a restricted portion thereof. v

Another object of the present invention is to provide a suction nozzle having} a single suction opening to a restricted portion of whichisfjapplied an agitator which may be moved intoor out of operative position. A further important object of the invention is to provide a suction cleaner which may apply suction to a wide area of the rug or which may apply more intense suction to a restricted area, the election of which may be made without manual manipulationof the nozzle by the. operator. A still further object of the invention is to provide such a nozzle in which the election ismade by a simple movement of the nozzle handle. whereby its relation to the nozzle body is changed in order to effect such election. Another object of the invention is to provide asuction nozzle of the type set forth in which the selection ofthe type of suction applied may be made without removal of the nozzle from the. surface being cleaned. Numerous other objects and features will be apparent from a consideration of the following specification taken in connection withthe ac companying drawings in which: I I Fig. l is a perspective view of a preferred embodiment of the present invention; 1 Fig. 2 is a bottom plan view of the nozzle 'dis'-" closed in Fig. l; 7 Fig. 3 is a sectional view taken on lines 3- 3 of Fig. 2 showing the assembly arranged for the ap'-= plication of suction to the entire length of thenozzle opening.

Fig. 4 is a view similar to Fig. 3 with the parts arranged for the application of intense to a restricted area; I Fig. 5 is a sectional view taken on lines 5 of; Fig. 2, and o Fig. 6 is a fragmentary detail view of the agitator of the present invention.

In general terms, the invention may be defined as comprising a nozzle body having a single elon-f suction gated suction opening, a central portion of which is divided by a baffle in combination with'a'suce' tion applying head which is bodily movableon the body of the nozzle in such a manner that the suction applying opening thereof may be selectively positioned to apply suction to the entire length of the opening or to that portion thereof.

defined by the bafile. I templates the use of an agitator which is movable into and out of operative relation by the bodily H movement of the head with respect to the nozzle; body.

I Referring more particularly to the drawings-the. nozzle is shown as comprising a body l0 having; a central arcuate upper surface II and a single. elongated suction opening including a central,

The invention also con-{ wide section [2 and narrower extending side sections l3. Mounted within the wide section 12 is a fixed baflle I4 secured in spaced relation from the front edge of the section l2 of the opening by securing screws l5 and brackets 16.

Mounted upon the arcuate surface ll of the body it) is a suction head 11 which is substantially hollow having a restricted suction applying apen ture H3 in the face thereof. The head [1 is movably secured to the body In by the engagement of side flanges l9 within arcuately shaped channel forming members 20. The arrangement is such that when a lifting moment of force is applied to the head it will slide forwardly on the surface II from the position shown in 3 to the position shown in Fig. 4. However, normal force applied to the head for simple forward and,

reverse movement of the nozzle on the rug will not induce such movement of the head within the channel forming members.

Suction is applied to the head from a conven= tional hollow operating wand or handle through a pivoted hollow connector 2| which is pivotaliy secured in the head H by suitable screws 22-. The head I! is preferably provided with an enlarged rearwardly extending portion 23 which has a rug contacting gliding surface 24 which in cooperation with elongated gliding surface 25 at the end of the nozzle provides for a smooth move ment with the nozzle over the rug surface when suction is applied by the elongated portion of the opening.

The baflle I4 is provided at its upper end with a rearwardly inclined and arcuately shaped surface 26 which acts in conjunction with the arcuate surface H of the head to guide the movement of the head with respect to the body and which also acts to insure application of intense suction to the restricted area of the opening in front of the baffle when the head is moved forwardly on the body as-shown in Fig. 4.

The brackets is terminate at their lower ends in an eyelet which receives the ends of a central supporting rod 29 upon which is mounted an agitator here shown in the form of a rotatable comb member 21 provided with teeth 28. At one end the member 21 is provided with a right angular disposed operating arm as within which is telescopically mounted a secondary arm 31 and which is normally pressed outwardly by an internal spring not shown. The extremity of the secondary arm 3| engages the head I! thus providing for rotary movement of the sleeve 21 on the rod 29 upon bodily movement of the head I} with m spect to the body l0. As will be noted in Fig. 3 when the head is in the rearward position with respect to the body and the suction is applied to the elongated portion of the opening, the sleeve is 'so-positioned that the teeth 28 thereof wil'l roll upwardly presenting to the rug a smooth-surface. When the head is moved forwardly on the body, however, the sleeve 2'! is rotated at counterclockwise manner to the position shown in" Fig. 4' wherein the teeth will be presented to the rug. surface so as to engage hairs and fine textile material to loosen the same" from the nap of theme. I

In the operation of the device the normal position for general rug cleaning is as shown in 3 the connector 2! isfree to pivot within the head. The surface 24- together with the surface 25 can ances' the middle for easy movement forward and backward over the rug surface. The application ment will not disturb the relation of the head T of said head.

with respect to the body. However, upon the application of a bodily upward movement to the connector 2 I, as distinguished from pivotal movement, the head i1 will slide forwardly on the-body 10 to the position shown in Fig. 4 and in so moving the agitator will be brought into operative position and the suction will be applied forwardly to the same i and the ntense suction to the res'trioted area in front of the baflie will be applied to the rug and at the same time the agitator will b'presented to that portion of the rug which is being siibjeoted to the intense suction.

-'0bv iously, numerous changes and modifications andthe full use of equivalents may be resorted to in the practice of the present invention without departure from the spirit or scope thereof as outlined in the appended claims.

What I claim is:

1. In a suction nozzle for vacuum cleaners, the combination with a body having a suction openmg therein, 'o'f' a partition dividing said opening} means applicable to selectively apply suction to either side of said partition, saidmeans compris mg a suction head bodily movable upon said body, an agitator carried by said partition, and means operativel'y connecting said agitator to said sud had for moving said agitator to an operative or inoperative position inresponse to movements 2 m a nozzle for suctioncleaners, a body having a narrow suction opening extending the length of the body and including an enlarged central portion, a partition in said body for divid ing the opening into one section extending the entire length or the body and a second section extending the length of the enlarged central portion of the opening, a rotatable comb supported by said partitionfor movement to an operative or inoperative position and a suction head mov ably mounted ori said body to selectively apply suction to either one or the other of the sections, and means operable to rotate the comb to operative position by and with movement of said head to a position for directing suction to the shorter. section.
