Abstract
Abstract The present invention relates to a multiple function control stalk for a vehicle having a linearly moveable wiper delay rheostat. The control stalk includes a plurality of switches for controlling various devices on the vehicle, such as the windshield wiper and washer controls and vehicle speed or cruise controls. A windshield wiper delay switch is provided on the control stalk which includes a rheostat having an arm which is linearly moveable in a direction generally parallel to the longitudinal axis of the control stalk. The wiper delay rheostat is disposed slightly above the body of the control stalk for easy viewing and manipulation by the vehicle driver. Movement of the arm of the wiper delay rheostat varies the electrical resistance thereof and, consequently, causes an electrical control circuit to alter the period of delay between successive cycles of operation of the windshield wipers.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A control stalk adapted to be mounted on a turn signal lever extending outwardly from a steering column of a vehicle for controlling the operation of a device within the vehicle comprising: a body portion having an elongated slot therein; and a rheostat enclosed within said body portion including an arm which extends outwardly from said rheostat and through said slot in said body portion, a first portion of said arm being linearly movable along a resistance element of said rheostat from a first end thereof to a second end, a second portion of said arm extending outwardly from said body portion through said slot to thereby permit an operator to vary the effective electrical resistance of said rheostat by movement of of said arm, the operation of the device being controlled in response to said effective electrical resistance.
Claim 2
Dependent Claim
139 words
A control stalk adapted to be mounted on a turn signal lever extending outwardly from a steering column of a vehicle for controlling the operation of a device within the vehicle comprising: a body portion having an elongated slot therein; and a rheostat enclosed within said body portion including an arm which extends outwardly from said rheostat and through said slot in said body portion, a first portion of said arm being linearly movable along a resistance element of said rheostat from a first end thereof to a second end, a second portion of said arm extending outwardly from said body portion through said slot to thereby permit an operator to vary the effective electrical resistance of said rheostat by movement of of said arm, the operation of the device being controlled in response to said effective electrical resistance.
Claim 3
Dependent Claim
22 words
The invention defined in claim 1 wherein said body portion includes a housing and wherein said rheostat is disposed in said housing.
Claim 4
Dependent Claim
179 words
A control stalk adapted to be connected to a turn signal lever extending outwardly from a steering column of a vehicle for controllig the operation of a device within the vehicle comprising: a generally cylindrical body portion; a switch assembly housing including an enlarged rear portion formed on said body portion, an upstanding flat panel formed on said body portion, and a cover removably secured to said rear portion adapted to extend therefrom to said panel to close said housing, said switch assembly housing defining a pair of opposed ends thereof; and a rheostat enclosed within said housing including an arm which extends outwardly from said housing through an elongated slot formed in said housing and which includes a first portion linearly movable along a resistance element of said rheostat from a first end thereof to a second end a second portion of said arm extending outwardly from said housing through said slot to thereby permit an operator to vary the electrical resistance of said rheostat, the operation of the device being controlled in response to said electrical resistance.
Claim 5
Dependent Claim
179 words
A control stalk adapted to be connected to a turn signal lever extending outwardly from a steering column of a vehicle for controllig the operation of a device within the vehicle comprising: a generally cylindrical body portion; a switch assembly housing including an enlarged rear portion formed on said body portion, an upstanding flat panel formed on said body portion, and a cover removably secured to said rear portion adapted to extend therefrom to said panel to close said housing, said switch assembly housing defining a pair of opposed ends thereof; and a rheostat enclosed within said housing including an arm which extends outwardly from said housing through an elongated slot formed in said housing and which includes a first portion linearly movable along a resistance element of said rheostat from a first end thereof to a second end a second portion of said arm extending outwardly from said housing through said slot to thereby permit an operator to vary the electrical resistance of said rheostat, the operation of the device being controlled in response to said electrical resistance.
Claim 6
Dependent Claim
17 words
The invention defined in claim 3 wherein said switch assembly housing is generally rectangular in cross section.
Claim 7
Dependent Claim
18 words
The invention defined in claim 3 wherein said switch assembly housing is disposed above aid cylindrical body portion.
Claim 8
Dependent Claim
26 words
The invention defined in claim 3 further including a button attached to said second portion of said arm extending upwardly out of said switch assembly housing.
Claim 9
Dependent Claim
19 words
The invention defined in claim 6 wherein said slot is formed between portions of said cover and said panel.
Claim 10
Dependent Claim
152 words
A control stalk adapted to be connected to a turn signal lever extending outwardly from a steering column of a vehicle for controlling a period of time between successive cycles of operation of a cyclically actuated device within the vehicle comprising: a body portion having an elongated slot therein; and first means for controlling said period of time between successive cycles of operation of said cyclically actuated device, said first means being carried by said body portion including an arm which extends outwardly from said first means, and through said slot in said body portion, one portion of said arm being linearly movable from a first end of said first means to a second end thereof, a second portion of said arm extending outwardly from said body portion, through said slot to thereby permit an operator to vary the period of time between successive cycles of operation of the cyclically actuated device.
Claim 11
Dependent Claim
152 words
A control stalk adapted to be connected to a turn signal lever extending outwardly from a steering column of a vehicle for controlling a period of time between successive cycles of operation of a cyclically actuated device within the vehicle comprising: a body portion having an elongated slot therein; and first means for controlling said period of time between successive cycles of operation of said cyclically actuated device, said first means being carried by said body portion including an arm which extends outwardly from said first means, and through said slot in said body portion, one portion of said arm being linearly movable from a first end of said first means to a second end thereof, a second portion of said arm extending outwardly from said body portion, through said slot to thereby permit an operator to vary the period of time between successive cycles of operation of the cyclically actuated device.
Claim 12
Dependent Claim
27 words
