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 co-action with the electrical contacts and/or a channel maze for co-action 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.

Claim 1
Independent Claim
248 words
A control device comprising, a case defining an interior linear slide chamber; a front wall on said case having an opening therein; a housing on said front wall overlying said opening in said case front wall defining an interior transverse cross-slide chamber in said housing relative to said linear slide chamber in said case; a cross-slide in said housing for transverse movement in said housing; a cam on said cross-slide; a linear slide in said case for linear movement in said case; said linear slide having a cam track receiving and engaging said cam on said cross-slide so that linear movement of said linear slide in said case effects transverse movement of said crossslide in said housing, means for moving said linear slide; said housing having a face wall; FPF ports in said face wall of said housing; means surmounting said ports for connecting said ports to FPF supply and use; 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; EMF contacts on 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 means 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.
