  • the bottom part of the front end ring 22 is also fixed at 31 to the casing 11 in a manner which will be described presently.
  • the front end ring is provided with a U-shape groove 32 about the periphery thereof which receives the front or forward edge of the casing 11, as illustrated in FIG. 5.
  • a suitable sealing gasket 33 is provided in the groove 32 about the extreme edge of casing 11 to provide an airtight joint.
  • a section 11a of casing 11, at the extreme forward edge thereof, is of slightly larger cross-section than the casing section immediately adjacent thereto, to provide a shoulder 11b against which bears an outwardly extending flange 34a at the open end of an apertured basket 34 in which the dust collecting member 21 is disposed.
  • the inner wall of the U-shape groove 32 is defined by part 22b of the front end ring having an inwardly extending portion which engages the flange 34a of the basket 34 to firmly hold the latter in position within the casing 11.
  • the inwardly extending part 22b of the front end ring 22 is also provided with a flange 220 which extends radially inward and at its inner edge is formed with a groove 35 which receives a sealing gasket 36.
  • the dust collecting member 21, which may be formed of paper permeable to air, is provided with a stiff cover 21a like cardboard, for example, which engages the gasket 35 and forms an air-tight seal between these parts(
  • the front end cover 12, which is pivoted at 37 to the front end ring 22 in a manner to be described presently, is provided with a hollow sleeve or tubular part 38 which extends rearwardly from the inlet 18.
  • the tube 38 projects through an opening in a closure plate 39 provided at the open end of the end cover 12 and fixed thereto in any suitable manner (not shown).
  • An annular gasket 40 is positioned in the gap at the opening in the closure plate 39 to seal the joint between the closure plate and tube 38.
  • the gasket 40 is provided with an outwardly flaring portion 40a which is disposed outside the closure plate and at its outer edge engages the dust bag cover 21a to hold the latter yieldingly against the gasket 36 to provide an air-tight seal therebetween.
  • the dust bag cover 21a is provided with a central opening which may be closed by a thin resilient membrane having split or overlapping parts 41 which yield and spread apart when the tube 38 projects through the opening in the dust bag cover 21a, as illustrated in FIG. 5.
  • the membrane parts 41 return to a flat position extending across the opening in the stiff cover 21a and seal the dirt in the dust bag 21.
  • a latch may be provided in the front end cover 14 for latching the end cover to the casing 11, as shown in FIG. 5.
  • the latch comprises a latch member 42 pivotally mounted on a pin 43 fixed within the front end cover 12, and a latch keeper 44 in the form of a pin extending between spaced lugs 45 projecting forward from the front end ring 22.
  • the latch member 42 may be formed of sheet metal and provided with a latching detent or catch 46.
  • a hairpin spring 47 surrounds the pivot pin 43 at the side of the latch member 42 with one leg 48 engaging the latch member and the leg 49 engaging a stop 50 in the cover 12. Thus, spring 47 yieldingly rocks the latch member 42 toward latching position.
  • a lug 51 extends upwardly from the latch member 42 between the pivot pin 43 and catch 46 and projects into an opening 52 in the front end cover 12.
  • a push button 53 is mounted on the lug 51 for manually pressing the latch member against the action of spring 47 to an unlatching position.
  • Latching member 42 also has a depending arm 42a which may be connected to other parts (not shown) in the end cover 12 in such a manner that, when the push button 53 is released and the spring 47 becomes effective to rock the latch member 42 counterclockwise, such upward rocking movement will be arrested to position the cam surface 54 on the nose of the latch member at a region at which the cam surface will engage the pin 44 when the end cover 12 is again moved to its closed position. With such arrangement, the pin 44 will automatically rock the latch member 42 clockwise until it moves to its locked position illustrated in FIG. 5.
  • the front wheel 16 forms part of a caster which is mounted at the bottom of casing 11 by structure including a member 55 which is fixed at 56 to the casing and provided with a central opening 57, as shown in FIGS. 4 and 5.
  • the caster includes a pair of cooperating parts 58 and 59 having antifriction rollers 60 therebetween, the top part 58 fitting in position at the underside of the member 55 and the bottom part 59 forming the closed end of a depending bracket 61 of inverted U-shape having spaced arms at the lower end of which the wheel 16 is mounted at 62.
  • the wheel 16 is rotatable about a horizontal axis at 62 which is eccentrically disposed with respect to a vertical axis at the region the bracket 61 is rotatably mounted at 63 on the member 55 at the opening 57 therein.
  • the bottom part of the front end ring 22 is secured at 31 to the casing 11.
  • this is accomplished by providing a horizontally extending part 64 across the bottom of the front end ring 22 which depends downwardly from the U-shape groove 32, as illustrated in FIG. 5.
  • the front of the part 64 is of convex shape and the rear thereof is of concave shape to provide a trough or groove 65 having end walls 66 provided with openings 67, as shown in FIGS. 5, 6 and 7.
  • Openings 68 are provided adjacent the ends of part 64 for receiving screws 69 having tightening nuts 70 disposed in square-shaped recesses 71 formed in lugs or bosses 72 provided at the bottom of the member 55 and depending downwardly therefrom.
  • the screws 69 fit snugly in U-shape notches 73 provided in the bosses 72 at opposing sides of the square-shaped recesses 71.
  • the front end ring 22 can be easily secured at 31 to the casing 11 by simply placing multi-sided tightening nuts in the square-shaped recesses 71 and inserting the screws 69 through the openings 68 so that they engage the nuts 70, the screws under these conditions resting in the notches 73 in front of the recesses 71.
  • the stabilizing prop is provided with an inner vertical wall 75 which depends downward from the member 55 and is of semi-circular or U-forrn, as best illustrated in FIGS. 3 and 4.
  • the wall 75 curves outwardly at the bottom part thereof and then upwardly at 76 to form wings or arms 77 which extend both longitudinally of and transversely of the casing 11, as best illustrated in FIG. 4.
  • the wing spread x of the arms 77 is greater than the distance y between the inner sides of the wheels 17, the outer parts of which approach vertical planes extending downward from the opposing sides of the casing 11. This will readily be evident from FIG. 3 where it will be observed that the arms 77 project laterally from the longitudinal center of the cleaner 19 beyond vertical planes passing through the inner sides of the rear wheels 17.
  • an effective prop for stabilizing the cleaner 10 is provided which effectively minimizes the tendency of the cleaner 10 to tip, irrespective of the position of the caster wheel 16 when it is being moved onto a rug at an edge thereof or from one room to another over a door threshold or sill.
  • the outer regions of the arms or wings 77 come in contact with the floor, rug or door threshold before the cleaner assumes a position of unstable equilibrium, thereby enabling the cleaner to move to its upright position when the condition causing the tilting passes.
  • the stabilizing prop 74 is of such shape that it extends lengthwise of the cleaner 10 for a considerable distance to provide gliding surfaces at each side of the caster wheel 16 having the curved shape indicated at 79 in FIG. 5.
  • This curved shape has a gradual slope from the rear of the stabilizing prop 74 to the lowest region 78 in FIG. 5 and then rises sharply to the vicinity of the front end ring 22. This will be evident from the fact that the inner vertical wall 75 becomes increasingly higher from the rear to the forward part thereof. Further, the trough formed between the vertical wall 75 and upwardly extending portion 76 joined thereto not only becomes wider from the rear to the front of the arms 77, as best seen in FIG. 4, but the radius of curvature of the trough becomes progressively larger from the rear to the front.
  • each arm 77 is convex both lengthwise and crosswise of the casing 11.
  • the bottom surface of each arm slopes upward from the lowermost zone 78 to provide a region of spherical form, the bottom surface sloping upward at one rate in a direction to the rear of the zone and at a substantially sharper rate to the front and outside of the zone.
  • the curve-shaped bottoms of the arms 77 provide rounded surfaces which become effective whenever the cleaner 10 is being moved forward onto a raised surface, such as a door threshold or the raised edge portion of a rug. Also, when the cleaner is being moved over a deep pile rug, the stabilizing prop 74 not only prevents tipping of the cleaner but the gliding surfaces of the arms 77 become effective skids to facilitate movement of the cleaner over the surface to be cleaned.
  • the front end cover 12 is hinged at 37 to the casing 11. In the preferred embodiment of the invention being described, this is accomplished by providing lugs 80 at the bottom of the front end cover 12 which extend rearward and downwardly therefrom, as best shown in FIGS. 3 and 7.
  • the lugs 80 are spaced apart a distance slightly greater than the length of the bottom part 64 of the front end ring 22, so that they will fit nicely over the apertured end walls 66 of the part 64 and provide slight clearance between these parts.
  • the front cover lugs 80 have openings 81 and are pivotally mounted on the bottom part 64 of the front end ring 22 by pins 82 having their heads 83 disposed at the ends of the trough 65.
  • the forward parts 75a of the inner vertical wall 75 of the stabilizing prop 74 are at the immediate vicinity of the front cover lugs 80 and overlie the outer surfaces thereof and in this way effectively conceal from view the outer ends of the pins 82.
  • the member 55 is first secured at 56 to the bottom of the casing 11.
  • the front end cover 12 is next piovtally mounted on the bottom part 64 of the end ring 22 by the pins 82, after which the front end ring 22 is secured to the end of the casing 11 by the screws 69.
