Abstract
Abstract This invention involves a governor mounted in the pulley of an automotive generator by a very simple adapter to make use of the bearings of the generator to support the governor. The governor has the characteristic of retracting a friction resistant plunger such as teflon at all speeds below a selected speed to be used to operate a valve to control a suction operated motor to actuate fuel shut off above said selected speed at closed throttle or to actuate a suction operated spark advance mechanism or other engine functions requiring a speed sensor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
95 words
A speed responsive device comprising a pulley having a hub with a radially outwardly facing surface and a rim having a radial surface and an axial flange with a radially inwardly facing surface, a speed governor having a housing and a stem extending therefrom for reciprocating movement in response to the speed of rotation of the governor, and means engaged with the housing and pulley for securing the housing in engagement with the radial surface and said inwardly facing surface, and with the stem in axial alignment with the axis of rotation of the pulley.
Claim 2
Dependent Claim
95 words
A speed responsive device comprising a pulley having a hub with a radially outwardly facing surface and a rim having a radial surface and an axial flange with a radially inwardly facing surface, a speed governor having a housing and a stem extending therefrom for reciprocating movement in response to the speed of rotation of the governor, and means engaged with the housing and pulley for securing the housing in engagement with the radial surface and said inwardly facing surface, and with the stem in axial alignment with the axis of rotation of the pulley.
Claim 3
Dependent Claim
33 words
A device as defined in claim 1 wherein the rim is V-shaped and the axial flange extends from a leg of the V and the radial surface is the surface of said leg.
Claim 4
Dependent Claim
84 words
A device as defined in claim 2 wherein the securing means comprises circumferentially spaced rods having a head at one end, each head having one dimension less than the distance between the bight of the V and the hub and another dimension greater than the distance between the bight of the V and the hub, whereby the heads can be inserted between the space between the bight of the V and hub and then rotated to lock or wedge the rods to the pulley.
Claim 5
Dependent Claim
115 words
A speed governor controlled valve comprising a generator having a housing pivotally mounted on a support, an armature shaft rotatably mounted in the housing, and a pulley having a hub mounted on the shaft, said pulley having a rim with a radial surface and an axial flange with a radially inwardly facing surface; a speed governor having a housing and a stem extending therefrom for reciprocating movement in response to the speed of rotation of the governor, and means engaged with the governor housing and pulley for securing said housing in engagement with the radial surface and inwardly facing surface, and with the stem in axiAl alignment with the axis of rotation of the pulley.
Claim 6
Dependent Claim
115 words
A speed governor controlled valve comprising a generator having a housing pivotally mounted on a support, an armature shaft rotatably mounted in the housing, and a pulley having a hub mounted on the shaft, said pulley having a rim with a radial surface and an axial flange with a radially inwardly facing surface; a speed governor having a housing and a stem extending therefrom for reciprocating movement in response to the speed of rotation of the governor, and means engaged with the governor housing and pulley for securing said housing in engagement with the radial surface and inwardly facing surface, and with the stem in axiAl alignment with the axis of rotation of the pulley.
Claim 7
Dependent Claim
52 words
A device as defined in claim 4 further including a valve housing having an inlet and outlet port mounted on the generator housing, a valve in said valve housing and means on said valve for engagement with the stem for shifting the valve to control the flow of fluid through the ports.
Claim 8
Dependent Claim
71 words
A device as defined in claim 5 further including a biasing means in said valve housing urging the valve toward the stem, a biasing means of greater force than the first mentioned biasing means in the governor housing urging the stem toward the valve, and centrifugal weights in the governor housing and in engagement with the stem for urging the stem away from the valve on a predetermined speed of rotation.
Claim 9
Dependent Claim
69 words
A mechanical operator comprising a generator having a housing pivotally mounted on a support, an armature shaft rotatably mounted in the housing, a pulley mounted on the shaft for connection to a source of power to drive the said shaft, and a speed responsive governor mounted on the pulley, said governor having an operating stem axially movable along the axis of the shaft in response to the speed thereof.
Claim 10
Dependent Claim
69 words
A mechanical operator comprising a generator having a housing pivotally mounted on a support, an armature shaft rotatably mounted in the housing, a pulley mounted on the shaft for connection to a source of power to drive the said shaft, and a speed responsive governor mounted on the pulley, said governor having an operating stem axially movable along the axis of the shaft in response to the speed thereof.
Claim 11
Dependent Claim
61 words
A device as defined in claim 7 further including a driven member for engagement and disengagement by said stem and means responsive to a preselected minimum speed of rotation of the pulley for urging the operating stem into driving engagement with the driven member, and means responsive to a speed greater than said minimum for disengaging the stem and driven member.
Claim 12
Dependent Claim
31 words
A device as defined in claim 8 wherein the driven member is a valve and a valve housing mounting said valve for reciprocation therein in axial alignment with the operating stem.
Claim 13
Dependent Claim
31 words
A device as defined in claim 9 wherein said housing has a fluid supply port and an inlet and outlet port for selective connection to the supply port by the valve.
