Cook, Los Angeles, Calif. (1050 Frederick St., Venice, Calif.) Filed Jan. 4, 1961, Ser. No. 80,648 2 Claims. (Cl. 15-327) This invention relates to improvements in vacuum cleaners and more particularly to a vacuum cleaner that is provided with a drum or cylindrical shaped outer casing that is supported at its opposite ends by substantially semi-elliptical shaped end portions that are so mounted in relation to the casing so that they are rotatable about the longitudinal axis of the casing to permit easy movement of the vacuum cleaner over any given surface.
An important object of this invention is, therefore, to provide a device of this type that is easily maneuverable over a given surface by reason of the fact that the outer casing thereof is provided with end portions that are freely rotatable either clockwise or counter-clockwise about the longitudinal axis of the casing.
Another object of the invention is to provide means for mounting rotatable end portions on a central outer casing so that the end portions may be easily removed from the central outer casing and then replaced as desired.
A further object of the invention is to provide the wand end of the flexible hose of the vacuum cleaner with a removable dust bag so that the dust bag may be removed and cleaned and replaced or renewed.

3,015,122 Patented Jan. 2, 1962 Referring more in detail to the drawings, wherein like parts are designated by like reference numerals, the reference numeral 15 is used to generally designate a vacuum cleaner embodying the invention.
The vacuum cleaner 15 comprises a central outer casing 16 which is the form of a drum or cylinder which is oriented so that the longitudinal central axis thereof is positioned in a horizontal plane. Mounted in the casing 16 is the usual motor driven suction fan assembly A that is in communication with a truncated conical suction inlet 17 that extends outwardly of the casing 16. However, since the motor driven suction fan assembly form no part of the present invention, it is believed that an illustration thereof is not deemed necessary or required.
The suction inlet 17 is provided with a nipple 18 whereby one end of a flexible exploring hose 19 is connected by means of a swivel connection 20 to suction inlet 17. Attached to the other end of the hose 19 is a rigid wand or tube section 21 to which suitable vacuum cleaner tools 22 may be detachably connected in the conventional manner. The casing 16 is also provided with a truncated conical shaped enlargement 23, through which a suitable electric cord 24 extends, whereby current is supplied to the assembly A. The central outer casing 16 has a circular end wall, not shown, that is provided with an outlet ring mount 25 thereon, whereby a dust bag 26, for receiving the dirt collected by the vacuum cleaner 15, is mounted in position, as shown in FIG. 2.
The outer casing 16 is also provided with a circular side or end wall 27 which has a centrally disposed opening 28 therein through which the assembly A extends, as also shown in FIG. 2. The side or end wall 27 and the side or end wall not shown, are each provided with three elongated slots 29 that receive a shaft 30 of a bearing block mount 31, there being three mounts 31 for each side or end wall, as shown in FIG. 2, one for each of the slots 29.
A pair of spacing washers 32 and 33 are mounted on each of the shafts 30 and the washers 32. and 33 space a wheel 34 on each of the shafts 30 outwardly of each of the side or end walls of the outer casing 16. The outer end of each of the shafts 30 is provided with threads, as shown in FIGS. 5 and 6, and a nut and washer assembly 35' threaded onto the outer end of each of the shafts 30 retain each of the wheels 34 on their respective shaft. Each of the mounts 31 is provided with a threaded bore 35 into which a screw bolt 36 extends, a screw bolt 36, therefore, will extend through an opening '14 that is positioned in the wall of the outer casing 16 adjacent each of the slots 29 to engage the threaded bores 35 in the bearing block mounts 31. Thus, when a screw driver B is utilized, as shown in FIGS. 5 and 6, the bearing block mounts 31 will be adjusted within the limits of the slots 29. Each of the screw bolts 36 has an annular groove 37 adjacent the head thereof and an O-ring 38 is received on the screw bolt 36 and mounted in the groove 37. The O-ring 38 prevents the screw bolt 36 from moving outwardly of the wall of the outer casing 16 without moving the bearing block mount 31 to which it is connected.
Semi-elliptical shaped end portions 39 and 40 are rotatably mounted on the opposite side or end walls of the central casing 16 and each of the end portions 39 and 40 are of similar shape, each having a centrally located outlet opening 41 that is covered by a wire mesh disc 42.
The inner peripheral edge of each of the end portions 39 and 40 are positioned over the wall of the outer casing 16 and the edges of the end portions 39 and 40 have rotatable engagement with a gasket 43, mounted on the outer casing 16 adjacent to the peripheral edge of each end or side wall thereof.
An annular groove 44 is provided in each of the end portions 39 and 40 and the grooves 44 receive the wheels 34 so that the end portions 39 and 40 are rotatably mounted on the central outer casing 16. When the end portions 39 and 40 are mounted on the central outer casing 16, the bearing block mounts 31 have been adjusted inwardly of the wall of the outer casing 16 so that the end portions 39 and 40 may be readily placed in position. After the positioning of the end portions 39 and 40, the bearing block mounts 31 are adjusted outwardly through the medium of the screw driver B rotating the screw bolts 36 and when an equal pressure of the Wheels 34 with the interior of the grooves 44 has been obtained the vacuum cleaner 15 is ready for use.
The vacuum cleaner 15 can be easily maneuvered over any flat surface by the operator pulling the vacuum cleaner 15 by means of the flexible hose 19 and in making any turns with the vacuum cleaner 15, one of the end portions 39 or 40 will rotate in the opposite direction from the other, as indicated by the arrows in FIG. 1, depending upon whether or not the operator moves to the right or the left of the vacuum cleaner 15.
To prevent damage to furniture, as indicated in FIG. 3, a tread member 45 of any suitable resilient material may be positioned on each of the exterior surfaces of the grooves 44 and to permit such action, the tread members 45 are of substantially U-shaped formation in cross section.
In FIGS. and 11 a short wand 46 is shown to be attached to a flexible hose 19 and into the open end of wand 46 there is adapted to be inserted, a disposable dust bag 47. The dust bag 47 has an annular flange 48 on the open end thereof that engages the open end of the wand 46 to prevent further inward movement of the dust bag 47 into the wand 46. The flange 48 also provides means for removing the dust bag 47 from the wand 46, as shown in FIG. 11. The dust bag 47 is used in addition to the dust bag 26 and provides easier disposal of the dirt collected by the vacuum cleaner when only a small area is to be cleaned thereby.
There has thus been provided a vacuum cleaner that is provided with rotatable end portions whereby the vacuum cleaner may be easily maneuvered over a flat surface and it is believed that the structure and operation of the vacuum cleaner will be clear to those skilled in the art.
It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to provided they fall within the spirit of the invention and the scope of the appended claims.
Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
1.
