' 6 Claims.
This application is a division of my copending application Serial No. 784,897 filed November 8, 1947.
The present invention relates to rug nozzles for suction cleaners which embody separately characterized rug cleaning apertures and surface engaging elements such that a plurality of types of cleaning may be accomplished by the use of a single nozzle.
The general object of the present invention is to provide a novel, simple and improved nozzle of the type set forth in which the structural arrangement is such as to facilitate manufacture and assembly and whereby the parts are securely united with the minimum of securing elements.
A specific object of the invention is to provide a novel assembly in which a pair of lip forming elements are jointly secured to the body of the nozzle by a novel and improved assembly arrangement which admirably lends itself to economy in manufacture and assembly, while insuring stability after such assembly.
Another object is to provide for a novel and improved bumper arrangement and locking means for securing the bumper on to the body of the nozzle.
Other objects and features of the present invention will be apparent from a consideration of the following specification when taken in conjunction with the accompanying drawings, in which;
Fig. 1 is a perspective view looking towards the top and front of the nozzle;
Fig. 2 is a similar view looking towards the bottom and back of the nozzle;
Fig. 3 is an exploded view of the nozzle shown in Figs. 1 and 2; and
Fig. 4 is a cross-sectional view of a portion of the nozzle taken on the line 4-4 of Fig. 3.
The nozzle of the present invention comprises a body member Ill preferably formed of a casting of aluminum or magnesium or similar light metal alloy. The top of the body I is reduced and provided with a small central high velocity aperture H which is surrounded with air directing channels I2 which are designed to direct incoming air through the aperture in a swirling vortex so as to apply an intense cleaning action when the topof the nozzle is applied to the surface being cleaned.
Adjacent the face of the top portion of the nating in rearwardly extending wing portions l5. Adjacent the lower edge of the body at the rear wall thereof there is provided a bottom bumperchannel is forming a seat in which is mounted the bottom rubber bumper l1. 1
The body ll] is substantially hollow, its rear wall being provided with an opening it within which is inserted the inner end 19 of a suction elbow or conduit 26. A socket M is provided within the body which receives the inner end of the elbow. The elbow 28 is cut away as at 22 to cooperate with the socket in such manner as to direct the flow of air through the aperture of the top when the nozzle is in inverted position in contact with the surface being cleaned and to direct the suction towards the open bottom of the body when the bottom is disposed towards the surface being cleaned. The elbow is also provided with a shoulder 23 by which it is secured within the body by the medium of the securing plate 26 which is engaged with the body by means of securing plate screws 25.
As will be noted more particularly in Fig. 3, the channels l3 and i8 terminate short of complete encirclement at points 26 and 2?, respectively, adjacent the rear opening it. The terminal points 26 and 21 of the channels are pro-.
vided with inwardly extending portions or depressions which receive the inwardly directed ends 28 and 29 of the respective bumper rings l4 and H. In Fig. 4 there are shown the depressions 21a at the ends 27 of channel it, and the depressions at the ends 26 of channel I3 are similar thereto. These depressions are blind, that is they do not extend all the way through the wall of the casting It, thus obviating the possibility of leakage of air into the interior of the nozzle at these points. It will be noted that at the terminal ends the bumper rings are of such configuration as to lie flush with the outer surface of the body adjacent the opening 18. With respect to ring ll, this is accomplished by indenting the outer surface of the ring adjacent to its ends, while the ends of bumper ring M are flush by reason of the fact that the depth of channel it in the rear wall of the nozzle body increases towards the points 26. When in assembled position the securing plate 24 engages over the flush terminal portions of the rings, thus securing the ends of the rings within their chan' nels. An inwardly directed fiange 3d of the securing plate also acts to overlie the terminal ends of the top bumper ring M to assist in securing it within its channel. I
While the top bumper ring it is mounted throughout its entire length within the upper channel I3 it will be noted that only the rear portion of the bottom bumper ring I! is so mounted. At the sides and the front edge of the body the bottom ring abuts a flange 31 and extends therefrom to a position below the bottom edge of the body. The downwardly extending portion of the ring l'i constitutes a flange 32 which is inwardly turned as at 33 to cover the terminal edges of the front and end walls of the body. The protruding portion 34 of the ring H is grooved as at 35 so as to receive .and be secured by the interfitting parts hereinafter to be described. From the following description it will be seen that the downwardly extending portion of the ring acts not only to assist in the securement of the front end portions of the ring, but also acts as a sealing means for the associated parts.
At a point intermediate its ends, each rear channel It is formed with an inwardly extending recess which is adapted to receive a projection 29a formed on each rear branch of the bumper l1. Apertures 2912 are provided in these projections and the rear wall of the nozzle body is formed with holes 2&0 extending inwardly from the bottom edge in alignment with the apertures 29?). Pins 29d are inserted through the holes 290 and the apertures 2917 so as to positively secure the central portions of rear branches of the bumper in the channels l6.
To assist in rotation of the body with respect to the elbow a weight 36 is mounted within the body at one side of the'elbow so as to dispose the center of gravity at a point displaced from the elbow whereby mere lifting of the nozzle from the surface cleaned will impart rotation thereto.
The present nozzle is provided with a lip forming rod QB which throughout its length is fitted within a circular groove 42 formed in the terminal edge of the rear wall of the body. The holes 29c terminate in the groove 42 and the presence of the rod in the groove retains the pins 2911 in place. One portion of the surface of the rod is formed with a longitudinal slot and a multiplicity of transverse slots which intersect the longitudinal slot and which together form a plurality of oppositely disposed surface agitating projections 44. In order to provide for a rotation of the rod so as to dispose either its smooth surface or its slotted surface toward the material being cleaned, one terminal end of the rod is provided with a right angularly disposed arm 45 which extends through a cooperating aperture in the body so that it may be conveniently manipulated from the top surface of the body.
The opposite end of the rod 48 is provided with fiat surfaces l which selectively abut a flat retaining spring 4,3 by which the rod is secured in its selected rotative position.
The rod 40 constitutes one surface engaging lip of the nozzle, while the opposite lip is formed by a plate 56 which extends downwardly and into the nozzle body and includes a transverse pair of flanges .1 which extend from the socket 2| outwardly to the ends of the nozzle body. These flanges 47? provide an upper boundary for the suction passage through the nozzle, and one of them also serves to retain the weights-6 within the nozzle body IS. The plate 66 also includes a forwardly directed section 68 which terminates in an upwardly turned flange 49 which latter is received within the groove 35 4 of the bottom bumper ring I! to secure the same in position.
As a means of agitating the rug surface, in a manner different from the agitation applied by the projections t4, the section 58 of the plate 46 is provided with an undulated or fluted central section through which air is drawn at a high velocity, while the nozzle is in operation.
Such velocity together with movement of the pile of a rug through contact by such undulations will increase the efficiency of the cleaning at this point.
The nozzle assembly is completed by the provision of a pair of end glider members 5i] which are secured to the body by suitable securing screws indicated at 5!, each member 5%! includes a downwardly inclined lower surface fastened at 5la which is adapted to engage the surface being cleaned to properly space the lips from such surface. The ends and sides of each member are turned upwardly to provide flanges 52 which encircle and engage the downwardly extending portion of the lower bumper ring 11. Themem bers 5!! also overlie the terminal ends of the rod 4?] securing it in position and also overlie the terminal ends of the plate 45, thus constituting unitary assembly means for securing the rod, the plate, and the lower ring Hi all in assembled relation with respect to the body.
From the foregoing it will be understood that the present invention provides a novel, simple, improved structural arrangement which admirably lends itself to economic manufacture and provides for new and improved cleaningaction. It will be understood that numerous changes and modifications in this structural embodiment herein presented will not constitute a departure from the scope of the appended claims.
