Abstract
Abstract A motion transmitting remote control assembly (10) of the type for transmitting forces along a curved path by a flexible motion transmitting core element (14) including a conduit (12) for slideably supporting the core element (14). An actuator assembly (18) including a handle (26) fixedly secured to a cable gear (24) engages a first core element (14) and imparts movement thereto. The first core element (14) has a first slug (58) fixedly secured on the end thereof. The first slug (58) is slideably retained in a passageway (60) defined by a sleeve (56), defining a first lost motion connection between the first core element (14) and the sleeve (56). A second core element (38) is provided for actuating a valve (36). The second core element (38) has a second slug (62) thereon and is slideably retained in the passageway (60) for providing a second lost motion connection between the second core element (38) and the sleeve ( 56).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
293 words
A motion transmitting remote control assembly (10) of the type for transmitting forces in a curved path by a flexible motion transmitting core element (14), said assembly (10) comprising: a conduit (12); a first flexible motion transmitting core element (14) moveably supported by said conduit (12), said first core element (14) having a first slug (58) disposed on the end thereof; actuator means (18) adapted for attachment to said first core element (14) and for imparting movement thereto; valve trip means remote from said actuator means (18) for actuating a valve (36) and including a second core element (38) having a second slug (62) disposed on the end (40) thereof; said assembly (10) characterized by lost motion connection means (52) including a housing (54) secured to said conduit (12) and a sleeve (56) slideably disposed in said housing (54), said first (58) and said second (62) slugs slideably engaging and supported by said sleeve (56) for establishing a first lost motion connection between said first core element (14) and said sleeve (56) and for establishing a second lost motion connection between said second core element (38) and said sleeve (56) said sleeve (56) having front and back walls for retaining said first (58) and second (62) slugs within said sleeve (56) so that said first slug (58) is moveable relative to said sleeve (56) and abuts said front wall of said sleeve (56) to move said sleeve (56) through a predetermined length in response to a force from said actuator means (18) without imparting movement to said second slug (62) and said second slug (62) is moveable relative to said sleeve (56) and abuts said back wall of said sleeve (56) to move after said sleeve (56) has moved through said predetermined length.
Claim 2
Dependent Claim
293 words
A motion transmitting remote control assembly (10) of the type for transmitting forces in a curved path by a flexible motion transmitting core element (14), said assembly (10) comprising: a conduit (12); a first flexible motion transmitting core element (14) moveably supported by said conduit (12), said first core element (14) having a first slug (58) disposed on the end thereof; actuator means (18) adapted for attachment to said first core element (14) and for imparting movement thereto; valve trip means remote from said actuator means (18) for actuating a valve (36) and including a second core element (38) having a second slug (62) disposed on the end (40) thereof; said assembly (10) characterized by lost motion connection means (52) including a housing (54) secured to said conduit (12) and a sleeve (56) slideably disposed in said housing (54), said first (58) and said second (62) slugs slideably engaging and supported by said sleeve (56) for establishing a first lost motion connection between said first core element (14) and said sleeve (56) and for establishing a second lost motion connection between said second core element (38) and said sleeve (56) said sleeve (56) having front and back walls for retaining said first (58) and second (62) slugs within said sleeve (56) so that said first slug (58) is moveable relative to said sleeve (56) and abuts said front wall of said sleeve (56) to move said sleeve (56) through a predetermined length in response to a force from said actuator means (18) without imparting movement to said second slug (62) and said second slug (62) is moveable relative to said sleeve (56) and abuts said back wall of said sleeve (56) to move after said sleeve (56) has moved through said predetermined length.
