Definitions

  • the present invention relates to vacuum cleaners and has for its object to provide a small, light weight, efiicient cleaner which can be used for a great variety of purposes.
  • Fig. 1 is a perspective View of my improved cleaner
  • Fig. 2 is a similar view showing the shoe detached from the cleaner
  • Fig. 3 is a sectional view of a part of the nozzle
  • Fig. 4 is a perspective view showing another arrangement for connecting the handle to the cleaner.
  • the nozzle 5 indicates the ,nozzle having suitable front and rear lips 6 and 7 against which the rug, carpet or other surface is adapted to be drawn by suction of the fan, when the cleaner is in operation.
  • the fan casing 8 Directly back of the nozzle and in communication therewith is the fan casing 8, the nozzle and casing being cast as a unit. To reduce the weight as much as possible these parts are made of aluminum.
  • the overall length of the nozzle is five and one-quarter inches.
  • the overall length of ,the cleaner exclusive of the bag is seven and a quarter inches.
  • Inside the casing is a fan shown in dotted lines in Fig. 1 and having a plurality of outwardly-extending vanes 9.
  • the aluminum housing 10 of a small high speed electric motor Secured to the back of the fan casing by suitable screws or bolts is the aluminum housing 10 of a small high speed electric motor. 11 indi- “cates the field magnet structure, 12 the field winding, 13 the armature and 14 the shaft therefor. The shaft is supported in suitable ball bearings contained in housing 10 of which the rear one 15, is shown.
  • the motor casing is provided with suitable ventilating openings 16.
  • the fan casing is provided with suitable ventilating openings 16.
  • a revolving brush20 Located inside of the nozzle on a horizontal spindle 19 is a revolving brush20 which is driven by a quarter turn belt 21 from a pulley 22 mounted on the front end of the motor shaft.
  • the s indle is mounted in ballbearings located in housings 23 carried by the end walls of the nozzle, the housings being held in place b screws 24; By loosening the screws the brush and its bearings can be removed by an endwise movement.
  • the cleaner can be used either with or with out the brush but for most purposes it should be used.
  • a handle 25 Permanently mounted on top of the cleaner is a handle 25 which is preferably tubular and ofinsulating material in order to re ceive the conductors 26 and the controlling snap switch 27, the latter being located on the underside of the handle where it can be actuated by the finger of the operator.
  • the conductors which are made of so-called flexible cord have an attachment plug 28 at their outer end for connection to a source of current supply and a branch 29 leading to the motor terminals.
  • the handle is su ported by front and rear brackets 30.ma e of pressed metal, one of which is secured to the fan casing and the other to the motor casing.
  • To the front bracket is secured a sheet metal cross-member 31 which supports a rest 32 and on which a thumb of the operator rests and by .means of which the cleaner can be tilted when necessary, in the cleaning operation.
  • a flat bottom shoe 35 is provided and which can be quickly and easily detached.
  • the shoe which maintains the nozzle in a normal operating position in parallel relation to the surface being cleaned, is shaped like a flatiron withthe tapered or pointed end located at the rear and slides on the surface being cleaned.
  • the under surface of the shoe is provided with three rollers 42 which may for simplicity be of the same character as those used on trucks and are exposed only on the underside. Of these rollers two are located at the front and one at the rear. These rollers are particularly serviceable when the cleaner is being used for floor coverings and the second handle used as will be referred to later.
  • the axes of the front rollers may with advantage be located in the same vertical plane as that of the brush axis.
  • the front of the shoe is provided with ears 43 which support the roller and also engage the ends of the nozzle, the latter feature serving as an additional securing means for the shoe and thus relieving the pins 36 1 of some of their load.
  • the cleaner as thus described is handled in about the same manner as a flat iron, the shoe serving to keep the nozzle lipsin their proper operating relation to the surface being cleaned, and being smooth on the bottom the operator can follow any curvature of the article being cleaned, as for example the seat covering of an automobile or chair.
  • the shoe is unnecessary and for that reason I so construct and ar-. range it that it can bequickly detached' and attached. In other cases part of the object may be cleaned with the shoe in place and the remainder without it.
  • a suit-able handle 44 is provided which can be easily attached to and disconnected from the.
  • the shoe is provided with a bridge piece 35 which is located at a point approximately under'the center of gravity of the motor.
  • the advantage of this over placing it at the rear end of the shoe resides in the fact that the pressure on the cleaner as a whole in mov ing it back and forth is applied at a nearly central point. If the point of connection of the handle is too far to the rear the pressure exerted thereby has a tendency to cause the rear end of the cleaner to be pressed into the surface and the front end to rise.
  • On the bridge is a lug 45 and embracing it on two sides are the legs of a clevis 46, the latter being secured to the handle. To en able the handle to be.
  • the shoe and motor are connected by the saddle 38, legs 39 and screw 41.
  • the motor clamping spring 40 of Fig. 1 is omitted and screw 41 is relied upon to hold the parts together.
  • the rollers 50 are located in open slots instead of being wholly underneath as before.
  • the handle 44 has two arms 51 which form a bail. The outer end of each arm is provided with a small opening to receive a fulcrum pin 52 which is permanently mounted in the upper part of the saddle and its support. The arms while stiff in the direction of movement of the cleaner when propelled by the handle are sufliciently elastic to permit of their being sprung over the pins 52.
  • the cleaner is very small and of light weight, as shown, weighing including all of the cord and exclusive of the handle 44 a little less than five pounds. As a result it can be used for long periods of time without undue fatigue of the operator.
  • the cleaner can be operated in three principal ways, first by the handle 25 with the shoe in place, second by the handle 25 without the shoe and third by the handle 44 with the shoe in place. Such a construction results in an all-purpose cleaner and as such has a wide variety What I claim as new and desire to secure by Letters Patent of the United States is 1.
