Jame s B. Kiria' Inve Attorne is Fatented May 19, 1931 UNITE STTES JAMES B. KIRBY, OF WEST RICHTIELD, OHIO SUCTION CLEANER Application filed November 5, 1927. Serial No. 231,197.

This invention relates to suction cleaners and has for its object the provision of new, improved and simplified means for securing the nozzle detachably to the cleaner casing and for detachably securing the wheels to the casing and for adjusting the elevation of the nozzle mouth relatively to the supporting surface. Further objects and advantages of the invention will become apparent as the description proceeds.

In the drawings accompanying and forming a part of this application I have shown certain illustrative embodiments of my inventive idea wherein Fig. 1 is a side elevation partly in section of an electric suction cleaner containing my improvements. Fig. 2 is a perspective View of the wheel and shaft assembly; Fig. 3 is a vertical sectional view through the middle of the shaft and adjacent parts; Figs. 4 and 5 are respectively an elevation and a longitudinal section of the lockin button; Fig. 5 is a cross-section of the lo king button; Fig. 6 is a front elevation of the cleaner and shaft separated, illustrating carried by a suitable bracket 7 of fixed elevation while the forward wheels 66 are journaled on the eccentric end portions 8-8 of a horizontal shaft 9.

The fan casing has a transverse forward wall 10 formed with a tapered central opening 11 and provided above said opening with a cam button 12 journaled on a suitable stud 13 and below that opening with a bracket 14" constituting a rigid part of the cleaner casing. In this particular cleaner said bracket is made as a separate part rigidly secured to the fan casing and formed near its upper part with a pair of spaced integral ears 15-15 which support the rigid horizontal rod 16 located on the opposite side of the opening 11 from the button 12 and'adapted to receive the slotted projections 17 carried by one side of the nozzle 3. 'This then constitutes a pivot or fulcrum about which the nozzle is rocked until the tapered end 18 thereof is seated in the opening 11 where it is held by turning the button 12 to engage a lu 19 at the top of the nozzle.

T 'e bottom of the bracket 14: is formed for the reception of the shaft 9. In the form of the invention shown in Figs. 1, 2, 3, and 8 the construction comprises depending fingers 2020 defining an open bottomed recess into which the shaft can be inserted from below and wherein it is held by an angular spring finger 21 secured in a suitable recess 22 formed in the back of the bracket and engaging a reduced portion 23 in the middle of the shaft. This spring therefore serves the double function of holding the shaft against falling out of the bracket and also fixing its lengthwise position in such bracket. The latter function can also be assisted, as shown in Figs. 2 and 3, by an auxiliary depending finger 24 which occupies the forward part of this reduced portion.

In the form of the invention shown in Figs. 6 and 7 the lower part of the bracket is formed with two journal-bearings 2525 apertured for the endwise reception of the shaft 9 which requires that one of the wheels 6 be removed for the application or removal of the shaft. The spring 21 is still used, however, and fixes the endwise position of the shaft by engaging the reduced portion 23 thereof.

lhe elevation of the inlet mouth of the nozzle depends upon the angular adjustment of the shaft 9, for which purpose the shaft is provided with a combined adjusting and securing button indicated generally at 31. 'In its preferred form this button comprises a hollow metal member having an internal axial bore of two diameters, defining a portion 32 which slides on the shaft 9 and an alined recess 33 of larger diameter which is formed interiorly with longitudinal slots 34, 34 adapted to receive the ends of the transverse pin 35 carried by shaft. Interposed between one side of the pin and the reduced portion 32 is a washer 36 and coil spring 37. The mouth of the recess 33 is closed by a ring 38 tightly pressed therein and slidable on the shaft. The end of the button adjacent the bracket 14 is formed externally With angularly spaced recesses 40 adapted to receive a fixed finger 41 carried by and projecting from one end of the bracket. When the button is slid length- Wise of the shaft by retracting the button against the tension of spring 37 (as shown in dotted lines in Fig. 7 it becomes possible to turn the shaft freely in its bearing and when it is released the engagement of the finger and recess holds said shaft in place. The exterior of the button is preferably knurled as at 42 to facilitate its manipulation and is also preferably marked with directions indicating the nature of the adjustment as shown in Fig. 4.
