Abstract
Abstract An apparatus for controlling electromotive force (EMF) and/or fluid pressure force (FPF) in a system having a case with walls defining at least one slide chamber and one or more intercommunicating cross-slide chambers. The case walls at the chambers carry circuit terminals for connection in the circuits of a system. The circuit terminals may be electrical contacts and/or fluid ports connected in a system by wires and tubes respectively. The slide and cross-slide carry circuit making and breaking means for connecting and disconnecting circuits in a system. The circuit making and breaking means may be a switch for coaction with the electrical contacts and/or a channel maze for coaction with the fluid ports. The slide carries at least one cam track and each cross-slide carries a cam lying in a cam track. With movement of the slide in one direction each cam track imparts transverse movement to each cross-slide at desired points of travel. The movement of the slide and the transverse movement of the cross-slide actuates the making and breaking means on the slide and/or cross-slide relative to the circuit contacts on the case to open and close circuits as coordinated in the engineering to the position of the slide and/or cross-slide.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
341 words
A control device comprising, a case having a front wall, opposite end walls, and opposite top and bottom walls; said case walls having interior surfaces defining an interior linear slide chamber in said case; said front wall having an opening therein intermediate said end walls and extending toward said top and bottom walls; a housing on said front wall overlying said opening in said case front wall; said housing having a face wall, opposite side walls, and opposite upper and lower walls; said housing walls having interior surfaces defining an interior cross-slide chamber in said housing relative to said linear slide chamber in said case; a cross-slide in said housing in sliding contact with said housing side walls and in spaced relationship to said housing upper and lower walls for movement toward and away from said upper and lower walls of said housing; a cam on said cross-slide extending into said case; a linear slide in said case in sliding contact with said case top and bottom walls and in spaced relationship to said case end walls for movement toward and away from said end walls of said case; said linear slide abutting said cross-slide to position said cross-slide in said housing; said linear slide having a cam track receiving and engaging said cam on said cross-slide so that linear movement of said linear slide between said case end walls effects transverse movement of said cross-slide between said housing upper and lower walls, a back wall on said case in sliding contact with said linear slide containing said linear slide in said case; means on said back wall for moving said linear slide to selected positions between said case end walls; FPF ports in said face wall of said housing, attaching means surmounting said ports for connecting said ports to FPF supply and use; and a channel maze switch-valve on said cross-slide facing said ports for selectably interconnecting and blocking fluid communication between said ports relative to FPF supply and use coordinated with the position of said cross-slide in said housing.
Claim 2
Dependent Claim
341 words
A control device comprising, a case having a front wall, opposite end walls, and opposite top and bottom walls; said case walls having interior surfaces defining an interior linear slide chamber in said case; said front wall having an opening therein intermediate said end walls and extending toward said top and bottom walls; a housing on said front wall overlying said opening in said case front wall; said housing having a face wall, opposite side walls, and opposite upper and lower walls; said housing walls having interior surfaces defining an interior cross-slide chamber in said housing relative to said linear slide chamber in said case; a cross-slide in said housing in sliding contact with said housing side walls and in spaced relationship to said housing upper and lower walls for movement toward and away from said upper and lower walls of said housing; a cam on said cross-slide extending into said case; a linear slide in said case in sliding contact with said case top and bottom walls and in spaced relationship to said case end walls for movement toward and away from said end walls of said case; said linear slide abutting said cross-slide to position said cross-slide in said housing; said linear slide having a cam track receiving and engaging said cam on said cross-slide so that linear movement of said linear slide between said case end walls effects transverse movement of said cross-slide between said housing upper and lower walls, a back wall on said case in sliding contact with said linear slide containing said linear slide in said case; means on said back wall for moving said linear slide to selected positions between said case end walls; FPF ports in said face wall of said housing, attaching means surmounting said ports for connecting said ports to FPF supply and use; and a channel maze switch-valve on said cross-slide facing said ports for selectably interconnecting and blocking fluid communication between said ports relative to FPF supply and use coordinated with the position of said cross-slide in said housing.
Claim 3
Dependent Claim
85 words
In a device as set forth in claim 1, EMF contacts on said housing leading to the interior surface of one said end wall of said housing adjacent said cross-slide, connector means on said housing connected to said contacts for attaching EMF supply and use lines to said contacts, and a switch plate on said cross-slide facing said contacts for selectably interconnecting and disconnecting electrical communication between said contacts relative to EMF supply and use coordinated with the position of said cross-slide in said housing.
Claim 4
Dependent Claim
97 words
In a device as set forth in claim 1, EMF contacts on said case leading to the interior surface of said back wall of said case adjacent said linear slide, connector means on said case connected to said contacts for attaching EMF supply and use lines to said contacts, switch means on said back wall facing said contacts for selectably interconnecting and disconnecting electrical communication between said contacts relative to EMF supply and use; and means on said linear side for operating said switch means coordinated with the relative position of said linear slide in said case.
