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.

BACKGROUND OF THE INVENTION Control programs for applying EMF and/or'FPF in systems are becoming more complicated and use more circuits while the space allotted to the control devices is becoming smaller. Thus the control devices are being called upon to handle more circuits and to be reduced in size. Also, the programs are becoming more varied in many uses so that the control device is also called upon to be adaptable'to handle many variations in programs in numerous systems.

SUMMARY OF THE PRESENT INVENTION With the foregoing in view, it is an object of the invention toprovide a control device which is reduced in size, which has capacity for controlling more circuits in a system, and which may be varied to suit various programs in many systems.

An object of the invention is to provide a case having a slide with relative motion and multiple positions between the slide and the case and a cross-slide with relative motion and various positions between the crossslide and the case.

An object of the invention is to use the movement of the slide to actuate'movement of the cross-slides so that they move with coordinated action.

An object of the invention is to provide cam tracks on the'slide' and a cam on each cross-slide lying in one of the cam tracks to impart movement to each crossslide in conjunction with movement of the slide.

An object of the invention is to provide cam and cam track actuationbetw'een a slide and cross-slides so that a 'portion'of the programmed control of the circuits may be engineered into thecam tracks.

An object of the invention is to provide cam and cam track actuation and program control so that the control ELECTRICAL device can be easily changed in its manufacture to suit DESCRIPTION OF THE DRAWINGS FIG. 1 is a top plan view of a control device embodying the invention indicating internal parts in broken lines and showing nipples at the F PF ports and an EMF terminal s't'rip.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT Referring now to the drawin s wherein like reference numerals refer to like and corresponding parts throughout the several views, the control apparatus for electrical an'd/or fluid force comprises, FIGS. 14, a case 20 having a cavity defining a first slide chamber 21 and a cavity defining a second slide chamber 22. A first slide 23 lies in the chamber 21 and a second slide 24 lies in the chamber 22. Cam tracks 25 and 27 are carried by the slide 23 and a cam track 26 is carried by the slide 24. An operating lever 28 is connected to the second slide 24 and an operating lever 29 is connected to the first slide 23. Movement of the operating levers 28 and 29 moves the slides 24 and 23 in the slide chambers 22 and 21, respectively.

Transverse cavities in the case 20 define cross-slide chambers 30 and 31. A cross-slide 32 lies in the crosschamber 31. A cam 33 on the cross-slide 32 lies in the cam track 27 of the first slide 23. A cross-slide 34 lies in the top of the cross-shamber 30.'A cam 35 on the cross-slide 34 lies in the cam track 25 of the first slide 23. A cross-slide 36 lies in the bottom of the crosschamber 30. A cam 37'on the cross-slide 36 lies in the cam track 26 of the second slide 24.

Relative to control of FPF, nipples 40 on the case 20 at thecross-chambers 30 and 31 surmount ports 41 in the case 20 at the cross-slides 32, 34, and 36. A channel maze 42 on the cross-slide 32 slides against the wall of the case 20 at the ports 41 and is resiliently pressed thereagainst by a spring 43 FIG. 8. The cross-slides 34 and 36 are similarly housed, formed, and equipped and the case 20 has ports 41 similarly integrated therewith.

Relative to control of EMF, a back wall 50 is mounted on the case 20, FIGS. 1-3. A terminal 51 connects to one side of EMF power supply. Spring switch arms 52 and 53 lead directly from the terminal 51. Cams 54 and 55 on the top slide 23 actuate the switch arms 52 and 53. Switch contact points 56, 57, 58, and 59 are carried by the back wall 50. The switch arms 52 and 53 engage the contact points 56 and 57 respectively when moved by the cams 54 and 55 upon movement by the top slide 23 as indicated by the broken line indication, FIG. 3. A cross-connector 60 is mounted on the back wall 50. Switch arms 61 and 62 are connected to the cross-connector 60 and are actuated similarly by the bottom slide 24 by cams as described relative to the top slide against the contact points 58 and 59. Leads 63 are connected to each contact point 56-59 as illustrated relative to contact point 59. The leads 63 are accumulated in a plug 64. The cross-connector 60 may be fixedly connected to the terminal 51 or it may be engaged by the actuation of a switch arm such as the switch arm 53 as shown. Thus the supply of EMF to the switch arms 61 and 62 may be made dependent on the actuation of another switch such as switch arm 53. This may be programmed in the control system so that an operator-user must first actuate a certain portion of a system before he may actuate another portion. Obviously the terminal 51 may be fixedly connected to the switch arms 61 and 62 rendering them independently operable.

- EMF control may also be provided at the cross-slides 32,34 and 36 as shown in FIGS. 9 and 10 relative to bottom cross-slide 36 and it will be understood that the other cross-slides 32 and 34 may be similarly equipped. Contact points 70-73 lie spaced inside the case in the cross-slide chamber at the cross-slide 36 and have exterior terminals 74-77 respectively for receptacle connection. A contactor plate 80 is carried by the cross-slide 36. A spring 8l urges the plate 80 toward the contact points 70-73. Movement of the cross-slide 36 carries the plate 80 relative to the contact points 70-73 to complete and interrupt circuits between the contact points 70-73 as engineered in the design of the system by the spacing and position of the contact points 70-73 and the size and shape of the plate 80 to control EMF ina system.

The location of the cams 54 and 55, FIG. 3, on the top and bottom slides 23 and '24, the placement of the switch arms 52, 53, 61 and 62, FIG. 2, the positioning of the contact points 70-73, FIG. 10, are engineered into the device for the system desired together with the location of the ports 41 relative to the channel maze 42 on each cross-slide 32, 34 and 36 and the channeling and blocking configuration of each channel maze 42, FIGS. 4-9, the independency or dependency of the circuits exemplified by the switch arms 52, 53, 61, and 62, and the angles and conformation of the cam tracks 25, 26, and 27, FIGS. 4-6, relative to the cams 33, 35, and 37 on the cross-slides 32, 34, and 36.

In operation F PF tubes, not shown, are connected on the nipples 40 between supply and use and EMF circuits, not shown, are connected to the terminals 51, 63, and 74-77. When the user swings the lever 29 it moves the top slide between the dotted line positions indicated and the solid line showings of FIGS. 3-6 during which the cams 54 and 55 actuate the switch arms 52 and 53 and the cam tracks 25 and 27 actuate the crossslides 32 and 34 via the cams 33 and 35 respectively relative to the ports 41. If the circuit to the switch arms 61, 62 is dependent, this also actuates the crossconnector 60.

Upon the user swinging the lever 28 it moves the bottom slide 24 between the positions indicated in broken lines FIGS. 1 and 4-6 and solid line positions shown, FIGS. 7-10, during which like cams 54 and 55, not shown, actuate the switch arms 61, 62, FIG. 2, and the cam track 26 actuates the cross-slide 36 via the cam 37 relative to the ports 41, FIGS. 4-10, and also moves the plate 80 FIGS. 9, 10, relative to the point contacts -73.

It will be understood that due to the interaction between the slides 23 and 24 and cross-slides 32, 34, and 36 that many EMF and FPF circuits can be controlled in coordination with one another in a very small space and that the device is capable of controlling a large plurality of circuits.
