Definitions

  • My invention relates to improvements in vacuum or suction cleaners and the object of my invention is to provide a manually operated cleaner for use in cleaning rugs, furniture, upholstery, etc., which is of high efficiency and can 'be simply actuated by the operator with the minimum of effort.
  • Another and important feature of my invention is to so construct my cleaner that it can be actuated by somewhat the same arm motions on the part of the operator, as are used in sweeping a floor with a brush.
  • my invention consists of a manually operated suction cleaner constructed and arranged, all as hereinafter more particularly described and illustrated in the accompanying drawings in which:
  • Figure 1 is a perspective view of my cleaner, in the position as it would be held in the hands of the operator.
  • Figure 2 is a longitudinal cross-sectional view through the suction inducing cylinder, piston, nozzle tube and dust receiving bag.
  • Fi ure 3 is a cross-sectional view through one head of one cylinder, being taken through the line 33, Figure 2.
  • Figure 4 is a cross-sectional view through the piston, being taken through the line 4-4,, Figure 2, and
  • Figure 5 is an enlarged perspective view of the dust receiving bag.
  • a cylinder 2 is carried in slidable relation to an aligned handle rod 3 and nozzle tube 4.
  • the handle rod 3 slidably protrudes from the top of the cylinder and the nozzle tube 4 slidably protrudes from the bottom of the cylinder.
  • the inner end of the handle rod 3 is secured to a hollow piston '5 carrying a fabric or leather piston ring 6.
  • the wall 1 of the piston opposite to the end of the handle rod 3, is formed with a central orifice 8, which opens into a cylindrical chamber 9 attached to the wall I, and in which a dust receivin fabric bag I l! is contained.
  • the open end of the chamber 9 is sealed by a detachable cover plate I l which is secured in place by a plurality of spring clips l2 attached to the outer face of the chamber.
  • nozzle tube 4 extends into the dust receiving bag l0 through an orifice in the cover plate H.
  • the cover plate I l is attached to the nozzle tube.
  • the ends of the cylinder 2 carry head plates l3 and I l.
  • the upper plate I3 is permanently attached to the cylinder 2, and the lower plate I4 is removably carried upon the cylinder 2, being secured by spring clips is attached to the outer face of the cylinder.
  • the head plates l3 and M are perforated with orifices l6 and I! which are positioned around the orifices I8 and 39 through which the handle rod 3 and the nozzle tube 4 respectively slide.
  • the outer faces of the head plates are covered by flexible leather or fabric discs Zlland 2
  • the discs are covered in turn by spaced protection plates 22, and the assemblies secured by rivets 23.
  • the nozzle tube 4 and handlerod 3 are an air tight sliding fit in the control orifices of the discs 20 and 2
  • the walls I and 24 of the piston are also perforated with'orlfices 25 and 26.
  • the outer faces of the piston walls are covered by flexible leather or fabric discs 21 and 28 which cover the orifices and act as flap valves.
  • the dust receiving bag I0 is formed with a lip 29 which is adapted to rest upon the outer'edge of the chamber 9 and be held in position under the pressure of the detachable cover plate II.
  • the outer end of the nozzle tube 4 carries a nozzle 3! of the standard'type.
  • extends from the top end of the cylinder to a point intermediately of its length.
  • the operator holds'the handle rod 3 in one hand and the cylinder handle 3! in the other hand; the vacuum cleaner resting upon the floor and'belng held at aninclinat on in the same manner as asweeping brush.
  • the handle rod 3 is pushed forwardly in relat on to the cylinder 2. which is held against movement'by the operator, the piston 5 moves from t e upper end to lower end of the cylinder. D ring this movement of the pi ton in t e cylinder a reduced air pressure is created in the upper end of the cylinder.
  • a suction cleaner of the character described a cylinder, a hollow piston reciprocal therein to create a reduced air pressure in the cylinder on one side of the piston, said piston having an air port in each of its side faces.
  • air suction operated valves controlling passage of air through the ports, a chamber carried by the piston and reciprocatingtherewith and communicating with the portion of the cylinder having a reduced air pressure, a dust receiving filter bag contained within the chamber, and a suction tube extending into the cylinder and into the chamber and having its inner end contained within the dust receiving bag.
  • suction tube extends into the cylin- 4 der at one end thereof and is reciprocal with the piston, and a handle rod extending into the cylinder at the other end thereof and secured to the piston and by means of which the piston is reciprocated.
  • piston air port valves are in the form of flexible discs positioned on the side faces of the piston to cover the air ports and constitute flap valves
  • the cylinder has a head plate at each end and has air ports in each head plate, and flexible discs positioned on the head plates to cover the air ports and constitute flap valves.
  • a suction cleaner of the character described a cylinder, head plates closing each end of the cylinder and having air ports therein, flexible discs positioned on the head plates to cover the air ports and constitute flap valves, a hollow piston in the cylinder and having a plurality of orifices in its side faces, flexible discs positioned on the side faces of the piston to cover the air ports and constitute flap valves, the piston being reciprocal in the cylinder to create a reduced air pressure in the cylinder at on side of the piston, a chamber carried by the piston and communicating with the cylinder through the air ports in the piston, a dust receiving bag contained within the chamber, and a reciprocal suction tube extending into the cylinder through one of the head plates and having its inner end positioned within the dust receiving bag in the chamber.
  • the chamber is provided with a detachable cover plate.
