VALVE CDNTRULLINE DEVICE.
(Application lerrA June 10, 189S.\ (N0 Model.)
. JOSEPH F. BATCHELO'R,'.OFQNEW Y' SPECIFICATION forming pgrtpf 'Letters Patent No. eaiedateamay e, 1899. A
Application filed J' une 10, 1898. Serial No. .683,149. (No model.) y l To all whom it iota/y concern/r l 'a citizen of the United States, and a resident of New York, (Brooklyn,), county of Kings, and State of New York, have invented certain new and useful improvements in Valve- Controlling Devices, of which the following ls a specification.
y My invention relatesto an improvement in valve-controlling devices, and is particularly addressed to the controlling-of a valve of,`
greater capacity bythe operationof a' valvev of less capacity. I have `.illustrated my invention in the accompanying drawing, in vwhich like letters refer to like parts.
The iigure is a sectional view of the valve, taken through the center thereof.
A is a valve of one capacity. B is a valve of less capacity than valve A, and'C is la cylinder andA piston rod. The valve B is intended to control Vpressure to the cylinder IC to operate the valve A. i
a'and a represent a valve-chest. CL2-and a2 represent avalve-seat interposed in said valvechest.l l
a8 is a valve-stem.
a4 is avalve-head secured` to the valvestem and seated in the valve-seat a2; 'Thel valve-head r4-and its seat a2 form a partition in thevalve-chest, forming two chambers a5 anda, one above and the other below the valve. Two arrows indicate the direction `in Vwhich pressure is suppliedv to and exhausted from these chambers 'through the ports a7 and a8. The valve-stem Vas extends through the 'p rheads ofthe valve-chest a' and a. A spiral v spring a9 around the `stem is preferably in-- `terposed between the valve-head aaud the- {rected to hold the valve-head seated. rA lelver am is pivoted at a and arranged to 'pass head of the'valve-chest with its tension di;
* through a slot al? inJ the lv'alve-stema3 and is preferably securedto a pull at cl2."
capacity than the valve A, which issuitably 'connected therewith.` f "l l 'bf is the valve-chest, b2 the valve-stem, and
a6 to the valve B below the valve-head b3.
. As stated, B is `an auxiliaryvalve oflessV b4 is a channel leading'fxom the chamber 4 i `bis a channel leading from the valveB Be it known that I, JOSEPH F. BATCHELOR,
joint isjformed in the partition or diaphragm X, separating the cylinder Cfrom the chamber a5, and preferably the i piston-rod and valve-stem are made in one piece. VThe pist0n-head c2 is provided with a port or exhaustpassage c3,"e xtending through thesame, and
'the cylinder is provided with a port or exhaust-outlet '04, open to kthe atmosphere or other space subject to minimum of pressure and is preferably of larger capacity than the ort ci when the pistonhead is against the same. performs an additional aud advantageous yfunction in that it limits the distance the port c3. Preferably there will be-'provided v `a seat to close the The s eat'c5 also main valve 'may be moved `fromits seat, act-` ing, therefore, as astop for the `main valve. It is apparent that the distance to whichlthe 'main'valve moves' is controlledI vvby the diss into the piston- ,tance that this seat extend chamber. f L v 4 The operationioftfhe valve and-.itscon'trolling devices is as -follows'z The pressure, beit steam orany other'prefssurewhich it is desired tocontrol bythe valve, enters -thecha'mber-a vthrough the portc, and thence .throughthe port or 1 channelb4 f into. the valve-chest b.
Thus the pressure lies belowthe valve-heads a4 and b3. `WhenE I `desire to open the valve A," I closev thev electriccircuit tothe magnet "be, thus energizing' thesaine and-causing the armature o7 to be attracted thereto,and as this armature-is connected -toloperate the valve B'the same 4isopened and 'pressure is admitted 4 through thesame Vand .the "port vor channel b5 into "thef'cylinder Cbefore the pis.`
` ton-head c2. The pressure thus admitted into the cylinder C operates 'to' move the pistonhead c2 in the cylinder C, and hence causes the piston-rod c' and valve-stem as to move the valve-head a4 away from its seat against the tension of the spring a9 and the pressure behind the valve-head a4. rlhis operation will take pla'ce for the reason that the pressuresurface. of the piston-head e2 is greater than the pressure-surface of the valve-head a4, and thus the valve A will be opened and the pressure will be allowed to pass through the valve A and chamber a5 out of port as. The valve A will thus remain open as long as the valve B is maintained open, for the reason that the ports b4, valve B, and port b5 are of sufficient capacity to admit pressure to the cylinder C to operate as described, while the piston-head c2 is exposed to minimum of back pressure, since the cylinder-space below the head is shut off from the chamber a5, in which there exists a pressure during the operation of the valve, and is freely open to the atmosphere or other space of zero pressure through the outlet c4. To reduce effectually any tendency to produce a pressure below the head c2, the area of outlet c4 should be made large relatively to the area ofthe passage c3. If, as described, when the head e2 is moved to the opposite extreme of its movement to that shown in the ligure the passage c`0 is closed against the seat c5, there will be no movement of the fluid through the passage into the space below the head, and consequently there will be still less of any tendency to create a back pressure while the piston-head c2 is moving toward the seat c5. When it engages the seat c5, the port c3 is thereby closed and the pressure lies before the piston-head c2 and holds the valve open.. It will be understood that the pressure-surfaces of the valve-head a4 and the piston-head c2 and the sizes of the ports are intended to be adj ustedby suitable means to create this balance of pressure necessary for the operation of the valve. y
I may of `course vary the form of exhaust above described by employing in the auxiliary valve B a hollow piston-rod in the usual form, so arranged that when the valve B is open the pressure will be admitted to the cylinder C and when the valve B is closed admit .of an exhaust from the cylinder C through 50 said hollow stem or slide-valve; but I prefer the arrangement shown, as it is a cheap form of construction. Vhen the valve B is closed, the tension of the spring a and the pressure bearing on the valve-head a4 operate to close the valve A and at the same time to compel the exhaust of the pressure before the pistonhead c2 through the port c3, and Athence the same will be exhausted through the port c4.
I provide the lever am for the purpose of operating the main valve A manually, ifdesired.
I haveshown electrical means for operating the auxiliary valve B. I may employ inechanical means to operate this Vvalve also.
It will be manifest that by the apparatus described I am able to control a valve of large capacity, as A, which requires the expenditure of aeomparatively large amount of power to operate the same directly, as with the lever am, by controlling a small auxiliary valve, as B, which requires a much less expenditure of power to operate the same, and I am able also by the arrangements of parts shown to combine with the means employed to control the valve electrically a convenient means of controlling the main valve A mechanically by the lever am or equivalent mechanical devices.
