ARTHUR E. WESTBURG AND GEORGE H. BATES, OF JAMESTOWN, NEW YORK, ASSIGNORS TO OI-IAUTAUQUA APPLIANCE COMPANY, OF JAMESTQWN, NEW YORK, A CORPORA- TION OF NEW YORK.
AUTOMATIC REGULATOR AND CUT-OFF.
Specification of Letters Patent.
Application filed September 14, 1908.
To all whom it may concern:
Be it known that we, ARrI-iuR E. TEST- BURG and GEORGE H. BATES, citizens of the in the county of Chautauqua and State of New York, have invented new and useful Improvements in Automatic Regulators and Gut-Offs, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
The present invention is an improvement on an automatic cut off shown in the application for Letters Patent, Serial Number 444,985.
The invention relates to safety devices.
periphery of the piston head 16. Plate 21 is then placed on stem 17 beneath packing 23 and is small enough to allow the leather packing 23 to be turned downward around the periphery of said plate 21. A number 50f smallwashers are assembled on stem 17 {between plates 21 and 22 and a suit-able nut confines all of these plates upon said stem ;as assembled. Plate 22 has openings 24 and particularly to inlet valves for fuel sup-. ply to engines or other fluid fuel consuming devices; and the object of our improvement is to so readapt the former construction as that regulating means may be added thereto for controlling the amount of fuel admitted to the burner so that when the pressure varies as it always does where there are a number of consumers taking fuel from the same main, the pressure will be constant and which also will act as a cut-off for the supply of fuel to the consuming device when the normal pressure in the main fails or is reduced from any cause.
In the drawings, Figure 1 is a vertical. sectional view of the regulator and the cutofi" mechanism in the set-up position. Fig. 2 is a perspective view of a tripping lever with its slotted ends and pivotal support. Fig. 3 is a plan view of the under side of the piston. Fig. 4 is a vertical sectional view of the device in the closed position for the cut-off.
The numeral 10 indicates a cylinder of.
suitable dimensions which has closed end caps 11 and 12. An inlet pipe 13 admits the fuel through the cap 11 to the lower end of the cylinder 10, which inletpipe is controlled by a double or two-way valve 14 which will be more fully hereinafter described. A discharge pipe 15 leads from the cylinder 10 atone side. A piston 16 is reciprocally mounted within cylinder 10, which piston has the stem 17 extending up through an adjustable sleeve 18 in top cap 12. Stem 17 between piston head 16 and the lower end of sleeve 18 is surrounded by a spiral spring 19 which forces the piston head downward, to balance the pressure 2 of the fuel in the cylinder and assists gravity in operating the closing of the valve 14, in the manner hereinafter set forth.
United States, and residents of Jamestown,
5 shaped plates 20, 21, and 22 and the leather Piston head 16 is composed of the diskpacking 23. The plates are assembled on Qthe lower end of stem 17 in the following manner: First, plate 20 is placed on stem. 1 17 fitting against a suitable shoulder on gsaid stem, the lower end of spring 19 restj ing against plate 20. Leather packing 23 is then placed on stem 17 next to plate 20 and large enough to extend out beyond plate 20 a suflicient distance to be returned downward about one-half inch around the entire therein to allow the fuel under pressure to enter the space between plates 21 and 22 in order to press outward upon packing 23 ;thereby giving an added resiliency to the packing and giving added efi'iciency thereto.
At the lower end of cylinder 10 a plate '25 is attached within cap 11 and has extending up therefrom a slotted lug to which is pivotallv attached an angular tripping :lever 26. Tripping lever 26 has a long and short arm, the upper end 26 of the long arm being adapted to engage piston head 16 and :be pressed down thereby as the piston moves downward. A spring 28 is attached around the lug on plate 25 to return lever 26 to its 34, which collar has a removable lower end 35 attached thereto by means of suitable set screw to receive on to said collar the slotted end 36 of the angular lever 37. Lever 37 is pivotally supported at 38 on a lug formed by a band passing around pipe 13 and the two ends are riveted together to form the double lug so that lever 37 may be pivotally attached therebetween at 38.
Valve 14 is provided with an inner partition 40 with a twoway valve seat 41 therein to receive the two valves and 43 on opposite sides. Valve 42 has a downwardly ext-ending valve stem 44 through the stutfing box 45 in the lower side of the valve casing and a collar 46 is attached to the lower end of stem 44, which collar is similar to collar 34 and engages the slotted end 47 of lever 37. It is now apparent that the downward motion of end 36 causes end 37 to lift upward on valve stem 44 and press valve 42 upon its valve seat.
An arm 53 extends upwardly from cap 12 and has pivotally attached thereto at 54 the arm 55. The slotted end 56 of arm 55 pivotally engages the upper end of stem 17 The opposite end of arm 55 is pivotally attached at 57 to the upper end of link 58, and the lower end of link 58 is pivotally attached at 59 to the upper end of valve stem 60 of valve 43.
To regulate the flow of the gas so as to give a constant pressure, the pressure of spring 19 upon piston head 16 is adjusted by means of adjusting sleeve 18 so as to balance the pressure between the spring 19 and the pressure of the fuel within the cylinder, and also so that valve 43 by means of the connecting links and arms to stem 17 will be automatically adjusted at the required dis tance from the valve seat to allow a constant flow of fuel through the valve seat. The spring trip 30 and lever 37 is set by hand, as shown in Fig. 1, with valve 42 off the valve seat, allowing the free flow of the fuel therethrough. Immediately upon a failure of the pressure from leak or other stoppage, the piston 16 passes downward by gravity and the pressure of spring 19 as soon as the pressure. of the fuel is removed, until plate 22 presses against the upper end 27 of lever 26, thereby tripping plunger 30 and allowing spring 33 to press valve 42 against the valve seat by means of lever 37, looking finger 49 locking the piston 16 in the lower position, as shown in Fig. 4, below the discharge pipe 15 so that should valve 42 for any reason leak, piston 16 forms a safety guard therefor.
With the return of the fuel pressure to pipe 13 beyond valve 14 in cylinder 10 the fuel is admitted to the cylinder by manually pressing upon the lower end of trip 30. Piston 16 is then unlocked by lifting upward upon weight 52 thereby swinging locking finger 39 out of the way of stop 48 al lowing the piston to resume its normal position and the fuel to fiow through the valve v14 and cylinder 10.
Our regulator and cut-off was constructed for natural gas, and since there is quite an amount of moisture condensed from said gas, an escape cook 61 is provided in lower cap 11 as an outlet for the drip accumulating from said moisture.
We claim as new:
1. In a device of the class described, a cylinder, a supply pipe connected thereto, a discharge pipe leading therefrom, a double valve controlling the supply to said cylinder, a tripping mechanism for operating one of said valves, means controlled by the pressure in said cylinder for operating said tripping mechanism, and connection between the second of said valves and said controlling means to adjust the connection of said second valve.
2. In a device of the class described, a cylinder, a supply pipe connected thereto, a discharge pipe leading therefrom, a double valve controlling the supply of said cylinder, a lever for operating one of said valves, a tripping mechanism for holding said lever in an operative position, a piston in said cylinder for operating said tripping mechanism, said piston controlled by the pressure of the gas in said cylinder, and connection between said piston and the second of said supply valves to control the same by said pressure on said piston.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
