or CLEVELAND, omo, a conroaarrou on emo OVABLE-BRUSH ATTACHMENT My inventionrelates to'improvements in removable brush attachment, and has for its object the provision of means for removably but vsecurely mountin a brush device upon a, suction nozzle. ore plarticularly, this `invention contemplates -t e provision of means for sliding-the brush.longitudinallyA into and out of its operative position upon the nozzle, for accurately' holding it in alinem` ment with the open mouth of the nozzle'without choking the opening, and for Vcompensatingany wearor looseness of t.

The' embodiment of my invention comprises an elongated, open-mouth suction nozzle having a longitudinal rim and an associated,l centrally slotted brush attachment provided with enacting slides fitting. removably uponl oe rim, together with resilient means, prefe ablyM 'thin the slide,for

'59 temporarily hold'ng and positioning the brush upon the nozzle.

'ti'lllihe several details lof construction, the u, owever, may st be explained in cong-, nection with the accompanyingl drawings illustrating preferred embodiments thereof, wherein: I Figure 1, is a; view in front-elevation nozzlel and brush attachment;

Fig. 2, is a view thereof in side elevation; Fig. 3, is a plan view, partially broken away and in section, showing the brush member,and v Fi 4, is a similar view of a slightly modified orm. Y l

. Throughout the several C'drawings I have employed figures A' of the the same character `of reference to indicate similar arts. A- As best shown in Eig. 2, the elongate hol, .40 low suction-cleaner nozzle a, terminating the'.` tubular portion a adapted for a hose attach-- ment, is provided with dongitudiml. l

.The coacting brush member 'b is provided with longitudinal slides la' openat one end and closed at the other to permit the mouth of the` nozzle accurately to register with the slot bf when the brush is positioned upon the nozzle. .A spring wire c, or opposing spring wires c, c are positioned @hin thesldes bso. asto eng e the rims a of the nozzle when the brush lsin place,
