Abstract
Abstract A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly. The system employs a motion conversion unit at either or both control and controlled station, said units serving to convert rotary motion into linear motion, and vice versa. That is, a force transfer shaft is rotatably mounted in the housing of the motion conversion unit to receive, or impart, rotary motion, and the core element of the push-pull control cable assembly -- which receives, or imparts, linear motion -- extends into, or through, the unit in transversely spaced relation with respect to the shaft. That portion of the normally flexible core element which extends into, or through, the unit is made rigid to impart columnar strength. A crosshead is secured to the rigidified portion of the core element and is slidably received within a first guideway presented from the housing to minimize lateral loading to the rigidified portion of the core element. The crosshead is also slidably received in a second guideway provided on a throw arm secured to the shaft. Movement of the crosshead simultaneously along the two guideways permits a conversion to be effected between the linear movement of the core element and the rotary movement of the force transfer shaft. A universal mounting plate is also disclosed which permits the unit to be mounted in a plurality of dispositions in order to suit the orientation required for various environments.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly, said system having a motion conversion unit comprising: a housing, shaft means rotatably mounted in said housing, a throw arm secured to said shaft means and movable within said housing, a core element included in said push-pull control cable assembly and extending within said housing, means to rigidify that portion of said core element extending within said housing, a crosshead secured to said rigidified portion of said core element and means to effect linear movement of said crosshead in response to rotational movement of said throw arm.
Claim 2
Independent Claim
106 words
A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly, said system having a motion conversion unit comprising: a housing, shaft means rotatably mounted in said housing, a throw arm secured to said shaft means and movable within said housing, a core element included in said push-pull control cable assembly and extending within said housing, means to rigidify that portion of said core element extending within said housing, a crosshead secured to said rigidified portion of said core element and means to effect linear movement of said crosshead in response to rotational movement of said throw arm.
Claim 3
Dependent Claim
57 words
A system, as set forth in claim 1, in which said means to effect linear movement of said crosshead comprises: a first guideway presented from said housing, said rigidified portion of said core element extending within said housing in substantially parallel orientation with respect to said first guideway and said crosshead being slidable in said first guideway.
Claim 4
Dependent Claim
57 words
A system, as set forth in claim 1, in which a first guideway is presented from said housing and a second guideway is presented from said throw arm, said crosshead being simultaneously slidable in said first and second guideways to accommodate linear movement of said rigidified core element in response to rotational movement of said throw arm.
Claim 5
Dependent Claim
34 words
A system, as set forth in claim 1, in which the means to rigidify said core element comprises a metallic sleeve swaged onto that portion of said core element which extends within said housing.
Claim 6
Dependent Claim
131 words
A system, as set forth in claim 1, in which said housing has a peripheral wall, a first guideway presented from said housing and extending between opposed locations along said peripheral wall, an anchor stub extending outwardly of said peripheral wall from at least one end of said guideway, a push-pull cable casing included within said push-pull control cable assembly, means to secure said cable casing to said anchor stub, said core element being slidably received within said casing and piercing said peripheral wall to extend parallel with said first guideway, a second guideway presented from said throw arm, said crosshead being simultaneously slidable in said first and second guideways to effect an operable interconnection between the rotational movement of said shaft means and the linear movement of said core element.
Claim 7
Dependent Claim
47 words
A system, as set forth in claim 1, in which a bracket is provided for mounting one or more switches, means on said throw arm to actuate said switches and means selectively to locate said bracket with respect to the range through which said throw arm moves.
Claim 8
Dependent Claim
49 words
A system, as set forth in claim 6, in which the means selectively to locate said bracket comprises: a plurality of arcuately spaced bores in said housing, at least one arcuate slot in said mounting bracket and clamping means extending through said slots to be anchored in said bores.
Claim 9
Dependent Claim
56 words
A system, as set forth in claim 7, in which the plurality of bores in said housing comprise at least five bores spaced at approximately 221/2° intervals and in which there are at least two slots in said mounting bracket, each said slot having an arcuate span of approximately 15° and being spaced approximately 30° apart.
Claim 10
Dependent Claim
39 words
A system, as set forth in claim 1, in which a mounting plate is provided for securing said motion conversion unit in selected dispositions with respect to the desired orientation of a push-pull control cable assembly operatively communicating therewith.
Claim 11
Dependent Claim
71 words
A system, as set forth in claim 9, in which a pair of tapped bores are provided in said housing in symmetrical relation, one on either side of said force transfer shaft, said mounting plate having a plurality of bores, the span between several pairs of said bores being equal to the span between said tapped bores to permit the mounting plate to be secured to said housing in various orientations.
Claim 12
Dependent Claim
73 words
A system, as set forth in claim 10, in which a central aperture is provided in said mounting plate to permit an operative connection to said force transfer shaft rotatably mounted in said housing, said plurality of bores in said mounting plate comprising at least five bores circumferentially spaced about said central aperture, the spacing of said first five bores providing four spans that are equal to the spans between said tapped bores.
