oascmrrioiv or run PREFERRED EMBODIMENTS Referring more specifically to the drawing and first with reference to FIGS. 1 to 8, the programmer in its entirety is designated generally 12 and includes an elongated laminated housing designated generally 13 composed generally of a top member 14, a second member-15, which is disposed im-' mediately beneath the top member 14, a third member 16 which is disposed beneath the member 15, and a bottom member 17. Each of said members 14, 15, 16 and 17 extend from end-to-end and from side-to-side of the housing 13.

The under side 18 of the top member 14 is recessed to provide spaced apart, substantially parallel longitudinally extending passageways .19, each of which extends to adjacent the ends of said member 14. Inlet nipples 20 have restricted threaded ends 21 which engage threaded openings 22 in one end of the member 14, so that a nipple 20 communicates with each passageway 19, as seen in FIGS. 2 and 4. The member 14- 'has a plurality of bores 23 which open upwardly through its top surface and downwardly into thepassageways 19, so that a row of bores 23 communicates with each passageway 19.

The member 15 constitutes a flat plate having bores 24 extending from top to bottom therethrough and which are disposed in alignment with the bores 23. A sealing gasket 25 is interposed betweenthe members 14 and 15 and around the passageways 19 for sealing off said passageways from one another. The member 16, which is substantially thicker than the member 15, is recessed to provide upwardly opening sockets 26 which are disposed to align and communicate with the bores 24 but which are substantially larger than said bores. The member 16 has threaded bores 27 which open upwardly into the sockets 26 and outwardly through the bottom surface of said member. A sealing gasket 28 is interposed between the members 15 and 16 and around the sockets 26 for sealing off the upper ends of the sockets 26. from one another and the lower ends of the bores 24 from one another.

The bottom member.l7 has channels or grooves 29 formed in its top surface and which provide passages which are disposed crosswise of said member 17 and of the housing 13. Each groove 29 communicates with a transverse row of sockets 26 through the bores 27 thereof which open into said groove 29, as seen in FIG. 3. Each groove 29 communicates with a threaded bore 30 of the member 17 which opens upwardly into said groove and outwardly through the underside of said member. A sealing gasket 31 is interposed between the underside of the member 16 and the upperside of the member FIG 8, each valve 33 includes an elongated stem 34 which extends through the bore 23 thereof and which has an annular groove 35 near its lower end to receive an annular sealing ring 36, and a second annular groove 37, which is disposed above and spaced from the groove 35, toreceive a second annular sealing ring 38. The valve stem 34 has a third annular groove 39 disposed between the grooves 35 and 37 and nearer the groove 35, to receive a flat split ring 40. When the valve 33 is in a closed position, as seen in FIG. 8, the ring 40 abuts the top surface 41 of the plate 15 around the bore. 24 thereof, which is in alignment with said valve, and the lower sealing ring 36 is disposed in and seals said bore, and the upper sealing ring 38 is disposed in the lower portion of the bore 23 for sealing the bore 23. When the valve 33 is in an open position, as seen in FIG. 3, the ring 40 abuts the top wall of the passageway 19 around the bore 23 in which said valve is mounted, the sealing ring 38 engages the upper part of said bore 23 for sealing the bore, and the sealing ring 36 is disposed above the bore 24, with which the valve aligns, so that said bore 24 forms a communicating passageway between the passage 19 and the socket 26 which registers with said bore 24. It will also be noted that the passageways 19 are of a width substantially greater than the diameter of the valves 33 so that said valves, when in a closed position, will not obstruct fluid flow through the passageways. The upper portions 42 of the valve stems 34 form handles by which the valves can be grasped and moved between their open and closed positions.

A ball valve 43 is disposed in each socket 26 and is supported by a weak compression spring 44 in the upper end of which a part of the ball seats. The springs 44 are contained in the sockets 26 beneath the balls 43 and have their lower ends resting on and supported by externally threaded tubes 45 which are detachably mounted in the threaded bores 27.

An outlet nipple 46 has a restricted threaded upper end 47 which engages the bore 30 so that a nipple 46 is provided for each channel 29. A flexible conduit or hose 48 leads from weachinipple46 to a machine, not shown, to be controlled by the programmer 12. A flexible conduit or. hose 49 connects with each nipple 20 and said hoses 49 lead from any suitable source of fluid supply. Posts or supports 50 may extend through the housing 13, adjacent its corners, and may be secured to any suitable supporting member, not shown, for supporting the programmer 12 so as to afford adequate clearance for the conduits 48.

From the foregoing, it will be readily apparent that fluid may be supplied to all or selected ones of the passageways 19 through the conduits 49 and fittings" 20 for pressurizing said passages. Selected ones of the valves 33 of one or more of the passageways 19 may be lifted upwardly to open positions. The fluid under pressure will then pass from the passageways 19 through the open bores 24 to unseat the ball valves 43 which are disposed therebeneath, as seen in FIGS. 2 and 3, so that the fluid can flow around the open balls and escape from the sockets 26 thereof through the tubes 45, into the channels 29 i with which said tubes communicate. The associated bores 24, :sockets 26, and tubes 45 thus form passages for supplying fluids to the channels 29 or to selected ones of said channels, which fluids will escape through the outlet nozzles 46 and conduits 48 thereof to the machine being controlled.

The housing 13 is shown provided with five longitudinal rows of valves 33, each row containing twelve valves making a total of sixty valves. Each longitudinal row of twelve valves controls the passage of fluid from one passageway 19 to the twelve channels 29, and each transverse row of five valves 33 controls the passage of fluid from the five passageways 19 to a single channel 29, so that a multiplicity of different patterns or combinations may be programmed by the device 12 to the machine being controlled.

The springs 44 are only of sufficient strength to support the ball valves 43 in closed positions seated against the lower ends of the bores 24. Said ball valves and springs are provided to prevent back feed into a passageway 19, which is not pressurized, due to a back pressure in one ofthe channels 29, and which would result in the fluid possibly escaping from the passageway 19 through the port 24 of another open valve of said passageway to incorrectly alter the programming of the machine.

FIGS. 9 and illustrate a slight modification whereby a 3 greater selectivity of the programming is accomplished by omitting the bottom member 17 and the gasket 31, and by removing the tubes 45 and engaging the threaded end 47 of an gram arrangements.

Various modifications and changes are contemplated and "may be resorted to without departing from the function or scope of the invention.
