VACUUM CLEANER BAG DUSTER Filed March 27, 1940 mlliam B; Veverg' wxf z Patented Feb. 18, 1941 PATENT OFFICE VACU M CLEANER BAG DUSTER WilliamB. Veevers, Nashville, Tenn. Application March 27, 1940, Serial No. 326,290
Claims. (01. 15-89) This invention relates to apparatus for removing dust and dirt from vacuum cleaner bags and an important object of the invention is to provide means whereby the bag may be agitated within a 'closed receptacle to prevent the. escape of dirt and dust into the surrounding atmosphere of a room. U a s More particularly the invention aims to provide a closed receptacle having a framev from which the vacuum cleaner bag is suspended, a crank upon the outside of the receptaclefor rotating the frame to turn the bag inside-out, and a beater extending through the top of the receptacle into a position within the bag for whipping the bag free of dust, either by oscillating the frame or the heater, or both.
Another object of the invention is to provide, in a device of the above character, means for supporting a removable container, such as a paper sack, below the vacuum cleaner bag for receiving the contents of the bag, when the latter is inverted, as Well as the dust beaten therefrom.
Other objects and advantages will become apparent from the following detailed, description of a preferred embodiment of the invention, reference being had to the annexed drawing, in which:
Figure 1 is a view in vertical cross-section through a vacuum cleaner bag duster, showing the bag turned inside-out ready for dusting;
Figure 2 is a view showing the manner in which thebag is initially placed in the bag duster and before the bag is inverted; and
Figure 3 is a detail view of the means by which the bag is clamped to the frame.
Referring to the vacuum cleaner bag duster i1- lustrated in Fig. 1 of the drawing, this device comprises a cylindrical dust receptacle I having closed bottom and side walls and a cover 2 removably fitted upon its top.
Below the top of the receptacle is a frame 3 including a ring 3a, of substantially smaller diameter than the receptacle I, and a pair of trunnions 3b extending from diametrically opposite points upon the ring through the wall of the receptacle so as to provide a rotatable support for the ring. One of the trunnions 3b is extended upon the exterior of the receptacle to form a crank 4 for manually rotating the frame.
The ring 3a is of such a size as to permit a vacuum cleaner bag 5 of the Electrolux type (which is about '7 inches in diameter and 8 inches in depth) to be introduced through the ring until its reinforcing band in comes to rest upon the ring. Apair of spring clips 6 mounted upon the ring are arranged to be sprung over the reinforcing band of the bag (see Fig. 3) and thus firmly clamp the bag to the Passing centrally downwardly through an oversize opening in the cover 2 is a rod 1 forming part of a beater, the lower end of the rod being looped 5 to providea flat impact member la, and its other end, lying outside the receptacle, being formed into a handle lb. A coil spring 8 surrounding the rod bears at one end against a ring 9, loosely surrounding the rod and closing the opening in the 10 cover through whichthe rod projects, and at its other end against a shoulder l0 upon the rod. The coil spring urges the rod upwardly so as to norm-ally retain it elevated in the position shown in Fig. 2, but permitting the rod to be pressed downwardly into the position shown in Fig. 1. A spring detent H is located on the outside of the receptacle to impositively retain the crank against movement in one of its positions.
Upon the inside of the receptacle l are a plurality of hooks l2 extending from the wall of the receptacle for engaging and supporting in open position a paper sack I3 below and surrounding the bag.
The operation of the vacuum cleaner bag duster is as follows: When the contents of the bag is to be emptied, the cover 2 of the receptacle I is removed. A paper sack is introduced into the receptacle through the clearance between one side of the frame 3 and the wall of the receptacle while the ring occupies a vertical plane, and the upper end of the sack is impaled upon the hooks l2 to retain the sack in open position overlying the inside of the receptacle.
The crank 4 is engaged with the detent ll so as to hold it in downward position with the ring occupying a horizontal plane as indicated in Fig.
2. Now the vacuum cleaner bag is introduced through the ring 3a and the clips snapped over the reinforcing band St to hold the frame against displacement. The cover is next placed upon the top of the receptacle, and the crank swung upward to rotate the ring through 180 degrees.
By pressing down upon the handle lb of the beater the rod 1 pokes the bag through the ring 3a to turn the bag inside-out and empty its contents into the paper sack [3. In order to free the bag completely of dust, either the crank 4 may be moved rapidly back and forth to swing the bag against the impact member Ia; or the crank may be held stationary and the beater oscillated by the handle lb, while maintaining the rod depressed against the coil spring 8, to whip the bag free of dust. Still more vigorous agitation of the bag maybe produced by simultaneously oscillating the beater with one hand and rocking the crank 4 with the other hand. By depressing the beater to various extents during operation it may be caused to strike different areas of the bag, thus insuring a more thorough cleaning of the bag.
After the bag has been agitated for a short time and the dust within the receptacle allowed to settle, the crank is turned into downward position to engage the detent H and the rod 1 is depressed to poke the bag through the ring to re-invert and restore the bag into its original condition. The receptacle now may be uncovered, the bag released from the ring 3a and withdrawn for reassembly in the vacuum cleaner, and the paper containing the dust and dirt then removed for suitable disposal. If desired, the paper sack can remain in the receptacle during several dusting operations and then removed with 7 closed receptacle including a removable cover, a
frame within the receptacle for supporting a vacuum cleaner bag in open position away from the wall of the receptacle, said frame being pivotally mounted for rotation; a. crank upon the 'outside of the receptacle operatively connected to the frame for rotating the frame to invert the same, and an oscillatable beater extending,
through the receptacle, said beater being longitudinally movable for movement into and out of a position within the bag, said beater being constructed and arranged for oscillation exteriorly of the receptacle for whipping the bag free from dust.
2. A vacuum cleaner bag duster comprising a closed receptacle including a removable cover, a frame within the receptacle including a ring for engaging the open end of a vacuum cleaner bag and supporting the bag in open position, said frame including trunnions for rotatably supporting the ring within the receptacle, clips for securing the bag to the ring, a crank upon the outside of the receptacle o'peratively connected to the frame for rotating the frame to invert the claim 2 including a detent for retaining the crank with the ring disposed in a horizontal plane.
5. A vacuum cleaner bag duster according to claim 2 including means for supporting a sack in open position Within the receptacle below the frame.
