UNITED STATES PATENT OFFICE.
EGBERT R. FIELD, OF DETROIT, MICHIGAN, ASSIGNOR TO EUREKA VACUUM CLEANER COMPANY, 01 DETROIT, MICHIGAN, A CORPORATION OI MICHIGAN.
COUPLING FOR VACUUM CLEANERS.
Original application filed March 20, 1922, Serial No. 454,060. Divided and this a 1923. Serial No. 614,326.
The invention relates to vacuum cleaning apparatus and has for its object the provision of a simple construction of coupling for securing the bag to the discharge of the fan casing, which permits of quickly securing or Figure 3 is atransverse section through the discharge of the fan casing and the coupling;
Figure 4 is a perspective view of a portion.
of the coupling.
The vacuum cleaner in the present instance has the motor casing 1, the fan casing 2 and the suction tool or nozzle 3 and is supported by the rolls 4 near opposite ends of the suction tool, and the castor wheel 5 near the rear end of the motor casing.
For detachabl securing the dirt retaining bag 6 to the tu ular outlet or discharge 7 of the fan casing 2, I have provided a coupling having a snap look. In detail, 8 is a tubular coupling member secured to the inlet end of the bag and adapted totelescopically engage over the tubular discharge 7 of the fan casing. This tubular coupling member has the annular outwardly extending bead 9 in its periphery forming in its inner face an annular groove adapted to receive the securing device 10 which is in the form of aresilient wire normally occupying the annular groove so that it will not interfere with the telescopic movement of the coupling member over the discharge. The bead has in its periphery the spaced apertures 11 as well as the zig-zag aperture 12, the latter having circumferentially extending end slots with laterally ofiset adjacent ends which-are connected by a transverse slot. The wire 10 has outwardly bent ortions 13 engaging in the apertures 11 and also has outwardly extending arms 14 and 15 engaging respectively in the near its end in which the wire 10 pplicetion filed January 22,
end slots of the zig-zag aperture 12 so that accidental disengagement of the wire from the tubular coupling member is prevented. One end 16 of one of the end slots of the zig zag aperture is enlarged to permit of the passage of the heads 17 and 18 uponthe ends of the arms 14 and 15 respectively to manually engage or disengage the wire with or from' the tubular coupling member. The tubular" discharge 7 of the fan casing is provided with: the annular roove 19 in its outer periphery is engageable when the latter is contracted to thereby secure the tubular coupling member to thetubular discharge.
To hold the wire in contracted position, the heads 17 and 18 interlock after they have been forced past each other to a position such as shown in Figure 4, the arms of the wire being resilient to permit of manual movement of these heads past each other to this osition. The shoulders 20 and 21 formed by t 1e edges of the transverse slot of the zig-zag aperture 12 engage the arms 14 and 15 respectively of the wire when the heads are interlocked to prevent further movement of the arms and further contracting movement of the wire. When the wire is in engagement with the annular groove of the tubular discharge its outwardly extending bends are still in engagement with their respective apertures of the tubularfcoupling member so that the bag is firmly secured to the discharge of the fan casing.
From the above description, it will be readily seen that I have provided a-simple construction of coupling for securing the bag to the fan casing, this coupling being so constructed that the bag may be quickly removed from or secured to the fan casing. Also, that the coupling has a snap lock which may be easily operated.
What I claim as my invention is: v
