HARPER F. SMITH, OF PHILADELPHIA, PENNSYLVANIA.
SPECIFICATION forming part of Letters Patent No. 693,170, dated February 1 1, 1902.
I Application filed October 31, 1901. Serial No. 80,623. (No model.)
To @ZZ whom t may concern:
Be itknown that I, HARPER F. SMITH, acitizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Fluid-Pressure Regulators, of whichthe following is a specification.
My invention relates to 'an improved construction of a duid-pressure regulator or governor'which is capable of a general application, but is especially adaptedl to be used in conjunction with hydrocarbon-'burners for automatically governing the Iiow of the liquid hydrocarbon to the burner, employed.
The invention consists inthe novel construction of the regulator, comprising a suitable casing having an inlet andan outlet for the hydrocarbon or liquid and means for forming al complete seal therein and for produc-l ing an air-cushion above said'seal under the control ofthe hydrocarbon, the air in said chamber 'being compressed by the unduly raised pressure in the reservoir to actuate the controlling-valve. Provision is made for the extinguishment of the burner in case the diaphragm breaks, and means also are provided for adjusting the tension on said diaphragm as may be desired.
Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically dened by the appended claims.
Figure 1 represents a vertical sectional low. which is` located thel seal -chamber 4,
which'latter isprovidedy with a drip 5 of any suitable construction. Y The chamber 4 is preferably formed between the base portion 6 and thetop 7, the latter havinga projection or projections 8, upon which are mounted the lever 9 bymeans of the pin 10, said le.. n
.Ver having one end of the link 1l connected thereto, while the upper end of said link is connected to the valve-stem 12, which' carries the valve 13, said valve being adapted to seat downwardly against the seat 14, above which is the chamber 15, with which contacts the flange 16, whereby the yalve 13 is guided according to requirements. g
17 designates aclosure for the chamber' 15, and 18 an outlet-pipe leading from said chamber 15.
19 designates a rod having its lower extrem-v ity pivotally connected to the lever 9, while its upper extremity is engaged with the stern 20, which depends from the head 21, which is capable of free movement ,with respect to' the base portion22 of Vthe diaphragm-.chamber 23, said base portion being connected tor `the tube 24, the lower extremity of which is in engagement with the top 7,` whereby it will be seen that an air-chamber 25 is formed betweenthe chamber f1 and the lower portion 26 of the stem 20.
27 designates a flange projecting from theV head and adapted to contact with an adjacent baseportion of the diaphragm-chamber, whereby the downward movement of said head 21 is limited according to requirements. 28 designates'a stem projecting upwardly from the head 21 and having at or near its eXf tremity the guide 29, which reciprocates in the threaded sleeve 30, which latter. is adapted to engage the' cap 3l of the diaphragmchamber 23. seen in Fig. l, screwed on the sleeve 30 to lock the same in its adjusted position. 32 designates a spring whoseupper extremity isadapted to abut against the lower wall of the sleeve 30, while the lower extremity 33 o f said spring contacts with the nut 34:, below which are located the diaphragms 35 and 36, the latter having the spacing-block 37 interposed bet-ween them-and itbeing apparent that the lower of saiddiaphragms issuperimposed upon theiiange 37, while the outer edges of said diaphragme are suitably held in position in any desired oreonvenient manner.
38 desgnatesa vent-pipe leading from the chamber 39 above the upper diaphragm 35 whereby any undue or excessive pressure can.
A lock-nut 30 is provided, as j be conducted from the diaphragm-chamber tothe atmosphere. This pipe, as seen clearly in Fig. 1, is so disposed as to extend outward, so that any escaping hydrocarbon or other liquid escaping above the diaphragm incase of' its breakage will be thrown away from the lamp, so as to avoid all possibility of confiagration or injury to the lamp.
In Fig. 2 I have shown a rod 19 as connected with the stem 40, which latter passes through the lower diaphragm 4l, upon which rests the nut 42, against the upper portion of which latter abuts the lower end of the spring 43, the upper extremity of said spring contacting with the nut 44, which is in engagement with the partition 45 of the intermediate portion of the easing 46, it being apparent that the stem 40 passes through the 11pper diaphragm 47, which latter is held in position with respect thereto by the jam-nuts 48, it being apparent that the diaphragm 47 is of greater area than the lower diaphragm 41, so that in case the latter is ruptured from any reason the pressure acting upon the upper diaphragm 47 of larger area will bodily lift the stem 19 against the tension of the spring` 43, and thus cause the regulator-valve, as 13, to immediately resume its seat. The partition or intermediate portion of the diaphragm-casing is provided with perforations 45', as seen in Fig. 2. In case the lower diaphragm breaks the pressure exerted on the upper diaphragm will force it upward, and this acting upon the lever will cause the closing of the valve 13, and the consequent extinguishment of the lamp.
It will be understood that the hydrocarbon or other liquid passing into the governor through the pipe 2 flows into the seal-chamber 4 and is retained therein by the air-cushion contained in the space2, so that when the pressure becomes unduly raised the hydrocarbon from the chamber 4 is forced into the air-cushion chamber, which in turn forces the air against the under or pressure surface of thelower diaphragm 36 or 41, whereby said diaphragm is raised against the tension of the regulating-spring 32 or 43, said spring being readily regulated, as is evident, whereby the exact tension and resistance desired can be attained. It will be understood that the air passes from the space 25 around the sides of the stem 20 and head 21 to the space beneath the diaphragm, the said stem being fitted sufcesare of the diaphragm, since the same will not be liable to rot or disintegrate, as it would if subjected directly to the action of the oil or hydrocarbon.
In Fig. 3 I have shown my improved governor or regulating device as applied to a hydrocarbon-burner, the preferred construction of which forms the subject-matter of a oontemporaneously-pending application filed by me July 1, 1901, Serial No. 66,650; but to the specific features of construction of this burner I have of course herein made no claim. In the construction seen in Fig. 3 I have shown the regulating device as applied tothe hydrocarbon-burner or vapor-lam p, wherein 61 designates the filling device, having the cap 62 for obtaining access thereto, said filling device communicating with the reservoir 63, from the lower portion of which hydrocarbon is conducted to the drip-chamber 64, from which leads the pipe 2 to the inlet-port of the regulating device. As has already been explained, the pipe 18 conveys the hydrocarbon from the regulating device to the vaporizing devices 65, which I do not deem it necessary to here describe in detail, since the same are constructed substantially in accordance with my contemporaneously-pending application above referred to, it being understood that a portion of the vapor is conveyed from said vaporizing devices to the pipe (56 to the fitting G7, mounted upon the reservoir 63, whereby pressure is exerted upon the top of the hydrocarbon in said reservoir, aportion of said vapor being reconveyed through the pipe 68 to the supergenerator 69 and thence through the pipe 70 tothe desired portion of the burner 7l. The operation of the burner will be familiar to those skilled in thisart, since it will be apparent that in starting the lamp suiiicient oil descends by gravity to the generator, so that when the starting device 72 is operated such oil is vaporized and is carried to the burner and lighted, after which the vapor is generated in the vaporizing devices 65 by heat from said burner, the supply of oil being kept up by the pressure of part of the vapor generated, such pressure acting through t-he oil or hydrocarbon in the governor to control the supply of oil to the generator. In the last throes of the lamp the vapor entering the inlet-pipe with the hydrocarbon passes out through the pipe 1S, because the liquid seal in the lower portion of the regulator will prevent its progress in the direction of the air-chamber, the liquid in the lower portion of the casing forming a perfect seal against any vapor that may pass in at the inlet by reason of its being the heavier body, and thus the air-cushion is completely shut off from communicationwith the inlet and outlet passages by said seal. The drip-chamber is con` nected with the starter by suitable pipe, as seen in Fig. 3, so that the oil therefrom may descend by gravity to feed the starter for the initial vaporization, after which the vapor is generated in the vaporizer 65, part of the va- ICO IIO
cearv por being consumed by the lamp andthe other portion passing to the top of the reservoir through the' pipe 66 'to exert its pressure on.
cially applicable lto vapor-lamps'l do not' limit myself thereto, since said governor is capable of being used in other positions and in connection with' othermeclianisms, as may be desired. 4
It will be apparent that various changes may be made by those skilled in the art which may come within the scope of my invention, and I donot'theret'ore desire to be limited in every instance to the exact construction I have herein shown and described.
