Abstract
Abstract A system for remotely controlling the setting of an adjustable element from a selected one of a number of control stations. The system includes an arrangement having a longitudinally movable operating slide having arranged in juxtaposed relationship on either side thereof a control slide arranged for individual movement with and parallel to the operating slide. The slides are connected to the adjustable element to be remotely controlled and are held mutually interconnected by latching means whose geometric axes meet each other in the neutral position of the arrangement. The latching elements are accommodated in channels and may be biassed axially inwardly by spring means. Between the latching elements, centrally of the operating slide, is a centre device providing indirect contact of the latching elements one with the other. The arrangement is such that activation of one slide causes similar movement of the operating slide while blocking movement of the non-activated slide.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
72 words
In a two station control system, two operating slides connected for operation from respective said stations, a control slide, each said slide having a neutral position, latch means carried by one of said operating slides for operatively engaging said control slide when said one slide is moved from its neutral position, and means responsive to said movement of said one slide to dog the other said operating slide in its neutral position.
Claim 2
Dependent Claim
72 words
In a two station control system, two operating slides connected for operation from respective said stations, a control slide, each said slide having a neutral position, latch means carried by one of said operating slides for operatively engaging said control slide when said one slide is moved from its neutral position, and means responsive to said movement of said one slide to dog the other said operating slide in its neutral position.
Claim 3
Dependent Claim
98 words
A system according to claim 1, characterized in that each said operating slide carries a respective latch means, said control slide comprises two side faces disposed respectively toward said respective operating slides, said latch means of each said operating slide being moved inwardly toward said control slide upon movement of the respective operating slide from its neutral position, latch-engageable means outwardly of each said operating slide, said control slide comprising means responsive to such inward movement of one said latch means to move said latch means of the other operating slide into dogging engagement with said latch-engageable means.
Claim 4
Independent Claim
171 words
A system common to a respective operating lever at each of two operating stations for enabling an adjustable element to be remotely controlled by said levers, characterized in that the system includes a housing which accommodates a control slide connected with the adjustable element and capable of being moved between a neutral position corresponding to a zero position of said element and control position corresponding to a control setting of said element, two operating slides each connected with a respective one of said levers for movement thereby, said operating slides being arranged adjacent said control slide, said element and slides having parallel paths of movement, each said operating slide having a neutral position corresponding to said zero position, and a latching and doggIng mechanism having latching elements operatively engaging between said control slide and said operating slides, said latching elements being arranged in response to movement of a selected one of said operating slides from its said neutral position to dog the other said operating slide in its said neutral position.
Claim 5
Independent Claim
171 words
A system common to a respective operating lever at each of two operating stations for enabling an adjustable element to be remotely controlled by said levers, characterized in that the system includes a housing which accommodates a control slide connected with the adjustable element and capable of being moved between a neutral position corresponding to a zero position of said element and control position corresponding to a control setting of said element, two operating slides each connected with a respective one of said levers for movement thereby, said operating slides being arranged adjacent said control slide, said element and slides having parallel paths of movement, each said operating slide having a neutral position corresponding to said zero position, and a latching and doggIng mechanism having latching elements operatively engaging between said control slide and said operating slides, said latching elements being arranged in response to movement of a selected one of said operating slides from its said neutral position to dog the other said operating slide in its said neutral position.
Claim 6
Dependent Claim
148 words
A system according to claim 3, characterized in that each of said slides has opposite faces and an aperture therethrough extending between said faces thereof, said latching elements being disposed in said respective apertures and having a dimension through said aperture greater than the distance between said faces of the respective slide, said control slide being disposed between said operating slides with one of said faces of each operating slide disposed theretoward, an aperture through said control slide, a housing having inner faces disposed toward the opposite ones of said faces of each operating slide, said inner faces being provided with apertures therein aligned, when said slides are in said zero and neutral positions, with said apertures of said slides, said inner faces being operative upon displacement of one of said operating slides to move the respective latching element thereof inwardly of said aperture of said control slide.
Claim 7
Dependent Claim
67 words
A system according to claim 4, characterized in that said apertures in said inner faces are provided with biasing means for opposing movement thereinto of the respective said latching element, and said inward movement of either said latching element moves the other said latching element out of said aperture in said control slide and into its respective inner face aperture against the bias of said biasing means.
Claim 8
Dependent Claim
54 words
A system in accord with claim 4 wherein said latching means have inclined outer surfaces disposed toward said inner faces and said inner wall apertures are defined by shoulders for camming the respective said latching means inwardly of said control slide aperture upon movement of either of said operating slides from such neutral position.
