UNITED STATES PATENT OFFICE.
JOHN W. NUNN AND THOMAS D. GRIFFIN, OF GRANGER, TEXAS.
Specification of Letters Patent.
Patented Aug. 21, 1906.
Application filed May 18,1905- Serial No. 260,998.
To all whom it ntcty concern:
Be it known that we, JOHN W. NUNN and THOMAS D. GRIFFIN, both citizens of the United States, residing at Granger, in the county of Williamson and State of Texas, have invented a new and useful Acetylene- Gas Machine, of which the following is a specification.
Our invention relates to acetylene-gas 'enerators, and has for its object to provi e a device of this kind in which the carbid is automatically fed to the generator by pressure of the gas under the movable bell and in which the gas generated is washed within the bell, thus avoiding the necessity of interposing the washer between the generator and the receiver.
The invention also consists of the novel features of construction hereinafter fully described, pointed out in the claim, and shown in the accompanying drawing. I
In the drawing we have shown a vertical section through the generator, carbid-holder, receiver, and bell, the movable parts and pipes being shown in elevation with the portions broken away to more clearly disclose the construction.
In the drawing, A represents the generator; B, the receiver O, the movable bell, and D the carbid-holder. The carbid-holder D is mounted upon the top of the generator A and communicates therewith through a contracted neck D. A pipe E is secured in the top of the carbid-holder D and extends downwardly through the neck D into the generator A, the pipe being open at each end. A rod E extends through and works in the said pipe and at its lower end is provided with lateral fingers E. A lever F is pivoted between its ends upon a standard G, and to one end of the lever F is pivoted the upper end of the rod E. A tube H slides upon the pipe E and carries a conical-shaped flange H, which forms a valve and is normally seated in the contracted neck portion B, securely closing the same and preventing the carbid from passing from the holder D into the generator A. A safety-gage pipe J is arranged parallel to the generator A and has an elbow fixed upon its lower end, from which a short pipesection J extends into the generator A. The
pipe J is opened at each end and serves both as a water-gage, from which the height of the water in the generator A may be determined, and-also serves as a vent should the generator becoine overcharged with gas. The pipe-section J also serves as an outlet through which the water into the generator and the carbid mud'can be drawn off, it being only neces sary to uncouple the pipe J. A pipe J 2 also extends through the top of the generator A to the point adjacent the bottom of the gen erator and is provided at its upper end with a funnel J This pipe also serves as a safetyvent, being opened at each end, and the funnel J 3 provides a convenient means for supplying the generator A with water. The pipe K leads from the upper portion of the generator A downwardly and passes through the sides of the generator A and of the receiver B, Where its lower end is secured in a suitable block L. WVithin the receiver B the pipe K is connected by a T-coupling to a gooseneck pipe K, the neck or bow portion of which is above the normal water-level and within the bell O, the discharge end of the pipe K being below the normal level of the water. The pipe K is steadied at its upper end by means of a T-coupling K which coupling is also threaded upon the lower end of the standard G, which lower end projects into the generator A. Between the generator and the receiver a suitable valve K is placed in the pipe K. A guide-rod L is placed vertically within the receiver and bell, the lower end of the guide-rod being fitted into the block L. A suitable tube L passes through the top of the bell and slides upon the guide-rod L, and a chain F connects the tube L with the end of the lever F opposite the end to which the rod E is pivoted. The gas generated within the bell is conveyed to the place of use through a vertical pipe M, the upper end of the pipe opening within the bell above the water-level and the lower end being connected, by means of a suitable coupling, to a service-pipe M, whoseinner end is threaded into the block L. The plug D closes an opening in the top of the carbidholdfr D, through which the carbid is supplie The operation of the device will be readily understood, and it will be obvious that as the gas generated within the bell lifts the same vertically the rod E and fingers IE will be permitted to descend within the generator and will be out of engagement with the lower end of the tube H; but when the gas within the bell has been drawn oil through the pipes M and M the bell will fall, carrying with it the tube L and drawing down the end of the lever F, to which the chain F is attached.
This will lift the rod E and the fingers E and the latter coming into engagement with the lower end of the tube H Will lift the said tube, and thus raise the valve H out of engagement with the contracted neck portion D and permit the carbid to fall by gravity into the generator until a suflicient amount of gas has passed into the receiver and bell to again lift the latter.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
In a device of the kind described a generator, a carbid-holder carried thereby and hav ing a contracted neck portion, a tube having a flange adapted to fit in said neck portion, a rod passing loosely through the tube and having fingers at its lower end adapted to engage the lower end of the tube, and means for lifting said rod vertically upon exhaustion of 20 a gas-supply.
