GAS-PRESSURE REGULATOR.
Specification or Letters Patent.
Application filed July 30, 1913. Serial No. 782,023.
To all whom it may concern Be it known that I, JAMES R. RIOKETTS, a citizen of the United States, residin at Los geles, county of Los Angeles, tate of have invented a new and useful Gas-Pressure Regulator, of which the following is a specification.
This invention relates to gas pressure regulators and the main object of the invention is to provide a valve which is slidably supported and always travels in a straight path toward and from its seat and is thereby always maintained in exact alinement with its seat and with the ports which it controls, and thereby when moved against its seat always perfectly fits thereon.
A further object is to provide for constantly lubricatin the valve to insure a smooth working t ereof and thus promote sensitiveness of the device and eliminate Wear, the presence of the lubricant acting in the manner of packing to prevent the escape of gas around the valve.
Another object is to provide simple means whereby the position of the valve seat may be regulated without taking the device apart.
Another object is to provide a simple means for regulating the pressure governing spring.
Another object is to provide an improved means for securing the connections intermediate the valve and diaphragm to those ele ments, whereby the parts may be very economically constructed and assembled, or taken apart.
Referring to the drawings: Figure 1 is a vertical longitudinal section of the device; Fig. 2 is a detailed sectional view of the diaphragm and its connecting element taken on line w -w Fig. 1; Fig. 3 is a perspective of the valve cylinder; Fig. 4 is a section on line zv*m Fig. 1; Fig. 5 is a section on line w -a2 Fig. 1; Fig. 6 is a section on line av -w Fig. 5.
The device comprises a pressure chamber 1, having a diametrical off -set recessed chamber 2, with outwardly diverging walls Fig.4, and'provided with bosses 4 and 5 for the attachment of inlet pipe 6 and outlet pipe 7.
8 designates one side of the chamber 1, and 9 is a cap removably secured to the chamber 1 by screws 10 and .retains and protects the diaphragm and is provided with a vent 11.
The boss 4 is provided with a smooth Walled opening 12 in which lies a removable thimble 13, the latter being externally threaded to engage andretain the base 14.
of a valve cylinder 15, but is slid-able'in the smooth walled hole-12 into and out of position, thereby enabling easy assembling thereof. The base 14, as shown in Figs. 3 and 4, has-beveled sides 16 which fit the converging walls 3. This construction serves togreatly facilitate the assembling of the parts as the walls 3 guide the base 14 into perfect valinement and center the cylinder 15 with the thimble l3, besides acting to firmly hold the base and cylinder in position when the thimble 13 is screwed into the base. .A washer 17 is interposed between the head of the thimble l3 and the inner wall of the boss 4 to prevent leakage. The thickness of this washer determines the position of the inner end of the thimble in the cylinder. If its position is to be changed a washer of different thickness may be substituted. The inner end of the thimble is beveled to form a valve seat 18,'and tsliding Within the cylinder 15 is a valve'lE), the lower portion of which is cupped and filled with a leather face 20, adapted to impinge against the seat 18 to shut off the supply of gas when the valve is entirely closed. The
The link 21 is connected to a T lever 26 which is pivoted to a lug 27 on the base 14 and is connected by a link 28 with a pair of lugs 29, which are struck up from a plate 29 which is secured to the diaphragm 8. The link 28 is similar in construction to the link 21 and thus is easily and quickly at tached or detached. The T lever 26 is formed with a hook shaped arm 30 against which the lower end of the compression spring 31 bears, the latter being guided in a socket 32 formed in the side of the ofiset chamber 2, and a screw 33 therein serves to adjustably give the requisite compression of spring 31 and is provided with a pin 34 to assist in guiding the spring 31.
.35 is a lock screw which may whenever it is set recess formed with an inclined socket, a spring with one end projecting into said socket, a pivoted lever having an arm a ainst which the spring bears, a diap iragm, a link between said lever and diaphragm, and a slidin valve connected with said lever and mova le toward and from said inlet.
3. In a gas pressure regulator, a chamber having an inlet and an outlet, a thimble in the inlet and having a beveled end formin a valve seat, a valve cylinder to which said thimble is screwed to hold the cylinder in position, such cylinder having a port, a valve sliding in the cylinder, a diaphragm in the chamber, and means operated by the diaphragm for sliding the valve.
4. In a gas pressure regulator, a chamber having an inlet and an outlet, a thimble in the inlet and having a beveled end forming a valve seat, a valve cylinder to which said thimble is screwed to hold the cylinder in position, such cylinder having a port, a
valve sliding in the cylinder, a diaphragm be removed desired to adjust the screw 33. in the chamber, means operated by the dia- In operation the gas passes from the pipe phragm forshding the valve, said valve be- 6 through the thimble 13, thence through ing cupped in its lower portion, and a yielding material in said cupped portion for coacting with said thimble seat.
5. In a gas pressure regulator, a chamber having an inlet and an outlet, a thimble in the inlet and having a beveled end forming a valve seat, a valve cylinder to which said thimble is screwed to hold the cylinder in position, such cylinder having a port, a valve sliding in the cylinder, a diaphragm in the chamber, means operated by the diaphragm for portion of said valve being cupped and provided with lubricating ducts.
6. In a gas pressure regulator, a chamber having an inlet and an outlet, a thimble slidable into and out of said inlet, a washer between the head of the thimble and the outer wall of the inlet, a valve cylinder with a base within said chamber, said base being screw-threaded to engage said thimble, a valve sliding in said valve cylinder, a diaphragm in the chamber, means operated by the diaphragm for sliding said valve, and a spring for opposing the movement of said diaphragm.
7. In a gas pressure regulator, a chamber having an inlet and an outlet, a diaphragm in said chamber, a spring opposing said diaphragm, a valve cylinder in said chamber, said valve cylinder having a port, a valve in said cylinder connected with said diaphragm, said cylinder having slots extending inwardly to the walls of the valve, and adapted to contain a lubricant having a paraflin base to lubricate the valve.
8. In a gas pressure regulator, a chamber having an inlet and an outlet, a valve cylinder at the inlet, a cylindrical valve with ports 22 into the chamber 1 and acts upon the diaphragm 7 to tilt the T lever 26 and compress spring 34 to an amount corresponding to the pressure, and the position of lever 26 assumed under this amount of pressure places the valve 19 in a corresponding position giving a certain opening between its face 20 and the seat 18. If the pressure lowers, the spring 34 acts upon the T lever 26 to cause the latter to raise the valve 19 and admit more gas to the chamber 1 until the pressure is raised, and as the pressure raises, the spring 34 is compressed by the corresponding reverse movement of the T lever 26 which lowers the valve 19 toward its seat 18, so that with the spring 34 set under a definite compression the device will automatically operate to admit more gas when the pressure in chamber 1 lowers, or to decrease the amount should the pressure within the chamber 1 rise above a definite point. The gas from chamber 1 passes out through pipe 7 to the place of use.

1. In a gas pressure regulator, a chamber having an inlet and outlet, a diaphragm in the chamber, a spring for resisting movement of the diaphragm, the chamber having an off-set recess with convergingwalls, a valve cylinder with a base, said base having inclined faces adapted to fit said converging walls, a valve sliding in said cylinder, the cylinder having a port, and means operated by the diaphragm for moving the "alve.
