Patented Dee-l6, 31913.
Application filed August 12, 1912. Serial No. 714,584.
- To all whom it may concern:
Be it known that I, EDWARD K. PARKER,
a citizen of the United States, and resident and more particularly it relates to electrically operated means for controlling the valve in such systems, whereby .the pneumatic pressure or power may be shut off or' let 'on instantaneously at the will of the operator, or shut ofi automatically at a predetermined degree of pressure.
While my invention is peculiarly adapted for automatically shutting ofi the pressure in pneumatic pressure apparatus, when the pressure reaches a predetermined point, it will be understood that the invention is by no means limited to such use. 1
In the drawings hereto annexed, which illustrate certain embodiments of my invention,Figure 1 is a diagrammatic view, partly in elevation and partly in section, of an automatically controlled pneumatic pressure apparatus; Fig. 2 is a vertical, central section through the pressure gag-e shown in Fig. 1.
Referring to the drawings, A is an airtight casin upon which is mounted a conduit B having an inlet port 6 and an outlet port 6, and forming in effect a part of the casing. Within said conduit B and located between said ports 6 and b is a valve seat 6 tor the valve C, said valve being slidably mounted in said conduit and piwotally connected at one end to a lever D, which is pivoted within said casing A at d and provided with a stud d. Mounted upon the bottom of said casing A in any suitable manner is an electro-magnet E consisting of an armature e, a guide-tube e and a coil 6 A spring is located within said tube e between said armature and the bottom of said tube; and said armature e is provided at its top with a hook or projection e and a inger .e". Upon a side .wall of said casing A is mounted another electro-magnet F consisting of an armature f, a guide-tube f and a'ooil P. A spring f is located within said tube f between said armature and the bottom .of said top with flfhOOk or projection f Slklably mounted upon an inner wall of said casing is a bolt G provided near one end with a'stud g, said bolt adapted to cooperate with said armature f to lock the valve C in open position as presently to be described.
A pressure gage H is mounted in the usual manner upon an extension B on the conduit B, and is provided with the usual dial h, index hand it and glass front k Said glass front has a central opening in which is rotatably mounted a metallic plug b preferably provided with a knob or handle 02 on its outer .end and having a metallic indicator h upon its inner end, said indicator being preferably hooked, or curved inward, at its free end as clearly shown in Fig. 2. A metal strip It serves as a metallic connection between said plug a and the extension B upon which the gage is mounted. It will be understood that the index hand h is in metallic connection with the extension. B through its pivot pin and the dial, and the casing of the gage.
Suitable electric connections for energizing the .elcctro-magnets F and E and actuating the device are provided as follows: For energizing the electro-magnet F the connection is, by the wire J rrom the strip h to one end of the coil 1; by the wire J from the other endof said coil f to the binding post is of the battery K; from the binding post Kby the wire J to the casing A, which -is in metallic connection withthe index hand It through pipes B, B and gage casing H. For energizing the electro-magnet E, the connection is from the binding post K. by wire J to the cQntact point L, forming one end of a normally {open switch; fnom the other contact point L of said switch by the wire J to one end f the coil 6 and by the wire J from the other end .05 said eoil e to the binding post is.
The operation .015 the device is as follows: rte operator desiring for example to inflate an automobile tire and automatically to shut cit the pneumatic pressure, say at a pressure of 30 pounds to the square inch, sets the indicator It at :30 upon the gage dial. The switch comprising contacts L and L is closed, .thereby closing the circuit which energizes the eleotro-magauet E and causing the anmature e to be drawn down from its normal position shown in dotted lines in Fig. 1 to the position shown in 5 111 lines in said figure. Upon its downward passage the hook a engages the stud d or the lever D and drawssaid lever downward, thus opening the valve C. It will be observed that the hook e is of such length that it has traveled a considerable distance upon its downward passage before it engages the stud d so that it strikes sharply against said stud and draws the lever D quickly downward The armature e, and consequently the valve C, is locked and retained in its depressed position by the sliding bolt G which is pushed forward by the armature f, actuated by the spring f into engagement with the end of finger e The valve being thus opened and locked in open position, the air or gas from a suitable source of pneumatic pressure (not shown) enters by the intake port I) and issues from the outlet port I). The pressure causes the inde'zr hand 11. to travel over the faceof the dial in the usual manner until it comes in contact with the hooked end of the indicator 72., thus closing the circuit which operates 'the electro-magnet F. When said electro-magnet is thus energized the armature f is drawn backward, and in its backward movement the projection i engages the stud g and withdraws the bolt G from contained within the valve casing which is tight against leakage and closed to the atmosphere except through the inlet port I) and through the valve. Thus, by this construction all danger of leakage due to defective packing or bushings is eliminated and furthermore the device may be made in .very compact form.
I claim:
'1. In a device of the class described, a
- casing having an inlet port and an outlet port, a valve, a seat for said valve located etween said ports, a lever pivoted in said casing, a connection between said lever and said valve, an electro-magnet mounted on said casing and having a spring-pressed armature adapted to cotiperate with said lover to open and close said valve, a bolt, another eiectro-magnet mounted on said casing having a spring-pressed armature adapted to codpera'te with said bolt to lock said valve in open position, a pressure gage ection f mounted on said casing and having a rotatably mounted indicator and an index hand, and an electrical connection between said last named electro-magnet and said gage whereby when said index hand makes contact with said indicator said armature cooperates with said bolt to unlock said valve.
