. M. EvLE'n-a- AGETYLENE GENERATOR 2 Sheets-Sheet l Filed Jan. l0. 1927 3513A@ @lt/tommy- Patented June 24,- 1930 UNITED STATES PATENT OFFICE EARL M. EVLETH, 0F GRAND HAVEN, MICHIGAN, ASSIGNOR TO BASTIAN-BLESSING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS ACETYLENE GENERATOR Application led January 10, 1927. Serial No. 160,040.
This invention is an improvement in acetylene generators, and relates more particularly to the mechanism employed for regulating and controlling the delivery of carbide t the gas generating or water chamber.
Certain features of my invention are designed as improvements on the construction disclosed in my prior application Serial No. 39,177, filed June 24, 1925.
In my present construction I employ a gas bell beneath which the gas is delivered, and which moves to actuate thecarbide feed mechanism.
As one important feature of my invention I subject the carbide feed mechanismto the action not only of the outflowing gas, but also the pressure of the gas in the generating chamber. ,f Y In the preferred construction, the carbide feed mechanism is agitated by the movement of the gas bell, but a brake is applied to prevent or retard such movement when the pressure exceeds a predetermined limit.
As a further important feature of my invention, I provide a carbide feed mechanism in the form of a valve plate which when in maximum open position will prevent the,
feed of carbide unless the valve plate be agitated. The valve plate is preferably mounted so that it may be 'raised and lowered in respect to the valve seat, but when in any position may have an independent movement, such as an oscillating movement, imparted thereto..
Other features of my invention will be apparent from a consideration of the drawings, or will be pointed out hereinafter.
In the accompanying drawings:
Fig. 1 is a sideelevation of a portion of a gas generator, certain of the parts being shown in vertical section, and
Fig. 2 is a sideelevation, certain of the parts being shown in section, on the line 2-2 of Fig. 1.
In the 'form illustrated, there are provided two main chambers 10 and l1, the lower chamber 10 serving as a water storing and gas generating chamber, lWhile the other chamber 11, which is at a higher elevation, serves as a carbide chamber or hopper. The
bottom of the hopper serves as the partition between the two chambers, and is of conical form with an outlet opening l2 at the lower apex end.
For controlling this opening I provide a valve 13 which is carried by a valve stem 14, and which in turn is carried by a pivoted arm 15. The lower side of the hopper has a, pair of lugs 16 in which is mounted the pivot pin 17 of they arm 15. Upon the outer end of the pivot pin 17 there is provided an operating lever 18. The upper end of this lever is engaged by an -eccentric 19 on a shaft 2() through the side of the carbide hopper. This shaft may be connected to the gas outlet valve lever in such a way that upon closing the gas outlet valve the lever 18 will be operated to lift the carbide feed valve 13 against its seat. The valve 13 is shown in the drawing in its maximum open position. It will be noted that it is considerably larger than the outlet or valve seat l2. The design is such that the angle of repose of the carbide will prevent any delivery from the hopper to 'the Water chamber when the valve isopen but at rest. The upper surface of the valve is a spherical section, and means are prothe generator exceeds a predetermined limit.
In the construction shown, a water chamber 2l is mounted on the side of the generator, and within this water chamber is a bell 22. Gas'is delivered to the chamber by an elbow or bracket 23 which opens into the upper part of the gas generatin chamber 10, and communicates with a pipe 24 eX- tending up into the water chamber beneath the bell 22. The chamber 2l has a main gas outlet conduit connected to the top 25.
The bell 22 is carried by a rod 26 which extends down through the pipe 24 and the lower end of this rod is connected to a bell crank lever 27. This lever is pivoted in the upper part of the gas generating chamber 10, and has one arm extending through the housing 23, and the other end extending down into the gas generating chamber and connected by a rod 28 to` a short arm 29 on the valve 13.
The chamber 21 is filled with water to a level determined by the filling plug 30 which is somewhatabove the lower edge of the bell. In operation, when the valve 13 is open, the gas will fiow through the passage 23 and pipe 24 to the under side of the bell, and will escape from the bell by bubbling beneath the lower edge thereof, and through the water. This bubbling causes constant agitation of the bell 22, and this movement is transmitted to the valve 13 to impart a constant oscillating oragitating movement to the latter.
Adjacent to the water chamber 21 I provide a casing 31 having a pressure diaphragm 32 therein. One surface -of this diaphragm is subjected to the pressure of the gas in the enerating chamber l0 through a connection 33 which is secured to the side of the hollow lbracket 23,'and which also serves as a bracket for supportin the diaphragm chamber. The other si e of the diaphragm is subjected to the action of a spring 34, the tension of which may be regu ated at .will by an adjustin screw 35. The diaphragm 32 is provide with means for preventing or retarding Ithe movement of the bell crank lever 27 when the pressure exceeds a predetermined limit. As shown, a pin 36 is mounted so that it may press against the side of the bell crank lever 27, and is connected by a lever 37 to the diaphragm. The lever ispivoted intermediate of its ends so that as the diaphragm 32 is pressed toward the left from the position shown in Fig. 2 by the action of high gas pressure, the pin 36 will move toward the right, and will press against the side of the lever 27. The greater the gas pressure in the generator, the greater will be the pressure of the pin 36 on the lever.
'As the pressure in the generator decreases,
the spring 34 will press the diaphragm in the opposite direction to release the lever 27.y To prevent the displacement of the lever by the lateral thrust, thereJ` may be provided an adjustable pin 38 upon the opposite side of the lever from the braking be altered without departing from the scope of my invention.
`Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An acetylene generator including a. carbide chamber, a gas generating chamber, a carbide feed valve of the poppet type movable vertically to open or closed position',said valve being of such size and such positioning when in full open position as to prevent the flow of a continuous stream of carbide from said carbide chamber to 'said gas generating chamber, and means for oscillating the valve-about its axis to effect a feeding action of the carbide.
2. An acetylene generator including a carbide chamber, a gas generating chamber, a carbide feed valve of the poppet type having a vertically disposed valve stem, and means for oscillatin said valve about the axis of its stem to e ect a feeding action.
3. An acetylene generator includin a carbide chamber, a gas enerating cham .1', a carbide feed valveof t e poppet type having a vertically dis osedy valve stem, means for oscillating sai valve about the axis of its stem to effect a feeding action, and independent means for moving said valve and its stem toward and from the carbide chamber.
4. An acetylene generator includin a carbide chamber, a gas enerating cham r, a carbide feed valve of te poppet type movable vertically to open or closed position, a water chamber separate from said gas generating chamber, a bell disposed therein, a conduit for delivering gas from the upper portion `of said gas eneratin chamber to a point beneath said ll, a be l crank lever having an arm projecting laterally into said conduit, and a depending arm projecting into said gas enerating chamber, operating connections etween the end of said first mentioned arm and said bell, and operating connections between the end of said second mentioned arm and said valve, whereby vertical movement of said bell imparts oscillatory movement to said valve.
