Definitions
- ABSTRACT ln accordance with the present invention, there is provided on the handle of a vacuum cleaner nozzle, or other electrical appliance, a member of conducting material so located as to be apt to be contacted at all times during use by the hand of the operator.
- This member is connected to both conductors of the 120 volt circuit of the appliance through a high loss dielectric material having resistivity high enough to prevent any significant current flow at 120 volts, either between the conductors or from either conductor to the person; but low enough to permit current flow at the high voltages of a static charge from the person to the conductors and at a rate sufficiently high to drain off the charge before the voltage reaches a high enough value to produce a spark discharge, but not at a rate sufficiently high to drain off an already accumulated high static charge rapidly enough to produce a spark discharge.
- a static charge is usually caused by friction and in a home the friction frequently results from a person walking on a rug or carpet.
- the moisture present makes the rug or carpet sufficiently conductive so that the static charge drains off toground as fast as it is generated and hence does not build up in the person.
- a high voltage static charge does accumulate and is suddenly discharged by a spark when the person happens to approach contact with a grounded object such as a radiator or a switch, or other static charge receiver.
- a very popular type of vacuum cleaner has a dust bag and a motor driven fan in a unit which sets on the floor and is connected to the suction nozzle by a flexible suction hose.
- many of these vacuum cleaners employ a motor driven brush in the nozzle and electric power for operating this latter motor is transmitted from the unit on the floor through conductors built into the hose.
- the static charge which tends to accumulate on the body of a person using a vacuum cleaner or other electrical device is continuously drained off by contact with the member of conducting material and passes through the high loss dielectric material to the conductors of the l20-volt circuit and through one of the conductors to ground.
- the charge never builds up to a voltage high enough to produce a spark discharge should the person grasp the hose or approach contact with a grounded object or any metal object of sufficient capacity to act as a static charge receiver.
- the operator is in no danger of receiving a shock from the l20- volt circuit inasmuch as the resistance of the high loss dielectric material is great enough to prevent the flow of any substantial current to the member of conducting material.
- the time constant of the circuit through the high loss dielectric material is long enough so that if a large charge is produced and then the operator comes effectively into contact with the member of conducting material, the charge drains off without sensation of shock.

- reference character 10 designates generally the unit of a vacuum cleaner system which contains a dust bag and a suction fan driven by an electric motor.
- the unit is movably supported on a floor by means of wheels 12 and a skid M, the motor being supplied with electric power through a flexible electric cord 16 having a plug 18 which may be connected to any convenient outlet of the usual l20-volt house circuit.
- a flexible electric cord 16 having a plug 18 which may be connected to any convenient outlet of the usual l20-volt house circuit.
- one conductor of such a circuit is grounded, but inasmuch as the plug I8 may be inserted in the outlet in either of the two possible positions, there is no way for the ordinary user to know which conductor of the circuit in the vacuum cleaner is grounded.
- a flexible suction hose 20 Connected to the unit 10 is a flexible suction hose 20 having conductors 22 and 24 disposed spirally within the wall 26 of the hose, as is shown in FIG. 2 and 3.
- These conductors are provided with the normal insulation which is sufficient to prevent the flow therethrough of any significant current at 120 volts. These conductors are supplied with power through an insulated lead or pigtail 28 which may be plugged into a receptacle on the unit It) which is connected to the l20'volt circuit in the unit.
- a metal tube 30 has one end thereof inserted into the hose wall 26 and secured therein by expanded ribs 32, the other end of tube 30 extending a substantial distance beyond the end of the hose wall.
- Disposed around the wall 26 is a tubular collar 34 of molded plastic or other suitable insulating material. integral with the upper part of the collar 34 is a receptacle housing 36. Supported in suitably shaped grooves molded in the housing 36 are electrical contacts 38 and 40. The conductors 22 and 24 are brought out of the end of the hose wall 26, as shown in FIG.
- a block 54 of a high loss dielectric material having resistivity high enough to prevent any significant current flow at 120 volts, but low enough and of adequately long time constant to permit current flow at the high voltages of a static charge and at a rate sufficiently high to, drain off the charge before the voltage reaches a high enough value to produce a spark discharge, but not at a rate sufficiently high to drain off an already accumulated high static charge rapidly enough to result in a spark discharge.
- a suitable value of the resistivity of this material is within the range of 10 to l ohms per cm. and the material may be a dielectric the resistivity of which has been decreased by the use of suitable plasticizing agents.
- the basic material may comprise polyvinylchloride of medium molecular weight plasticized with alkylphthalate esters, alkylsebacate esters, epoxidized fatty acids esters and combinations thereof in proportions that ensure the resistivity consistant with the compatability and stability of the mixture.
- An example of a resin-plasticizer combination that has desired performance characteristics consists of 100 parts polyvinylchloride (PVC), and a plasticizer comprising 71 parts dioctyl phthalate, 50 parts butylbenzlphthalate and 7 parts epoxidized soybean oil by weight proportions (a total of 228 parts).
- PVC polyvinylchloride
- plasticizer comprising 71 parts dioctyl phthalate, 50 parts butylbenzlphthalate and 7 parts epoxidized soybean oil by weight proportions (a total of 228 parts).
- This platicized resin has a resistivity of 1.67 X ohms per cm.
- a blade 56 of metal which is integral with a semi-circular ring portion 58.
- a bearing sleeve 60 of plastic having a radial flange 62 is disposed around the outwardly extending portion of tube 30.
- Disposed around sleeve 60 is one end of a metal tube 64 having a radial flange 66.
- Ring portion 58 is located between flanges 62 and 66 and hence is in electrical conducting relationship with tube 64.
- Cap member 50 of housing 36 has a skirt portion 68 which, when the cap is in position, is flush with the end of tubular collar 34 and is formed with an internal groove 70 which is in alignment with and forms a continuation of a similar groove formed in collar 34.
- a split lock ring 72 is received within these grooves and radially overlaps flange 66 so as to retain tube 64 on the end of the hose while permitting the hose to swivel relative to the tube.
- Tube 64 preferably is bent, as shown in P10. 1, the opposite end being insertable into a hollow tube or wand 74 connected to a suction nozzle 76.
- the latter is provided with a rotary brush driven by an electric motor which is supplied with 120 volt electric power through a cord 78 extending through a channel in wand 74 and terminating in a plug 80 having prongs 82 which may be inserted through openings 52 in cap 50 so as contact the upper rectangular portions of contacts 38 and 40.
- the operator grasps the bent tube 62 in order to move the nozzle 76 back and forth over the rug. if during this use a static charge is generated in the operator as previously explained, it is continuously drained off through the metal tube 64, the ring 58, which is in sliding conductive contact with the flange 66 of the tube, and through the blade 56 and the block 54 to whichever of the shanks 46 or 48 is in the grounded side of the l20-volt house circuit. Consequently, the static charge never builds up in the operator to a voltage sufficient to cause a spark discharge should he or she grasp the hose 20 or approach contact with a grounded metal object, such as a water pipe or radiator.
- the resistivity of the block 54 is sufficiently high to prevent the flow of current at 120 volts to the operator through 56, 58, 66 and tube 64, or between the shanks 40 and 48.
- FIGS. 6 and 7 the inventionis shown as applied to a portable electric drill designated generally by reference character 100.
- a portable electric drill designated generally by reference character 100.
- such a device has an electric motor which is supplied with the usual l20-volt current through a cord having a pair of conductors 104 and 106 therein. This cord enters a hollow handle 108 which is grasped by the operator when the drill is in use. Operation of the motor is controlled by a trigger switch 110 located in a convenient place relative to the handle.
- a block of material 112 of the same nature as the block 54 in the first embodiment.
- the conductors 104 and 106 extend through this block and the latter is secured in close contact with a metal plate or button 114 disposed on the outer surface of the handle so as to be contacted by the hand of the operator when grasping the handle.
