Abstract
Abstract A non-linear control device responds to cable core movement of a push-pull cable to control a pump through the rotation of a pump control shaft. A flange member, which is mounted on the pump housing, has a cam plate pivotally mounted thereon for movement about an axis parallel with the control shaft. The cam plate has an arcuate cam slot provided therein. A radially extending shaft lever of the control shaft has a bearing cam follower at its extended end which is operatively disposed within the cam slot. The cable core is attached to the cam plate at a point remote from the axis to cause the cam plate to move in response thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
A non-linear control device responding to movement of a cable core of a push-pull cable to control a pump means through rotation of a control shaft of said pump means comprising: a flange member fixedly attached to a housing of said pump means; a cam plate rotatably attached to said flange member for pivotal movement thereon about an axis which is parallel with said control shaft; said cam plate having a arcuate cam slot provided therein; said control shaft having a radially extending shaft lever with a bearing cam follower mounted on the extended end thereof; said bearing cam follower being operatively disposed within said cam slot; and said cable core being attached to said cam plate at a point remote from said axis.
Claim 2
Dependent Claim
124 words
A non-linear control device responding to movement of a cable core of a push-pull cable to control a pump means through rotation of a control shaft of said pump means comprising: a flange member fixedly attached to a housing of said pump means; a cam plate rotatably attached to said flange member for pivotal movement thereon about an axis which is parallel with said control shaft; said cam plate having a arcuate cam slot provided therein; said control shaft having a radially extending shaft lever with a bearing cam follower mounted on the extended end thereof; said bearing cam follower being operatively disposed within said cam slot; and said cable core being attached to said cam plate at a point remote from said axis.
Claim 3
Dependent Claim
34 words
A non-linear control device in accordance with claim 1 in wHich said cam plate extends parallel to said flange member, said arcuate cam slot contoured to conform to the edge of said cam plate.
Claim 4
Dependent Claim
59 words
A non-linear control device in accordance with claim 2 in which said pump is a variable displacement pump of a pump-variable, fixed displacement motor transmission system, said cam plate being provided with a series of apertures arranged around an arc equi-distant from the center point of rotation of the rotatable attachment of said cam plate to said flange member.
Claim 5
Dependent Claim
55 words
A non-linear control device in accordance with claim 3, said push-pull cable being provided with an end fitting fixedly attached to the conduit of said push-pull cable, a stabilizing bar fixedly attached to the flange member, said push-pull cable being attached to said stabilizing bar at said end fitting by means of a plate member.
Claim 6
Dependent Claim
40 words
A non-linear control device in accordance with claim 4, a seat means fixedly attached to said flange member providing a seat for a spring-biased ball which selectively registers with a detent provided on the inner face of said cam plate.
