Speciiicaton of Letters Patent.
Patented Aug. 15, 1905.
Application filed November '7, 1904. Serial No. 231,606.
To all 'wh/0111, it may concern.-
Be it known that I, JOHN T. Lrsrrnn, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Bunsen Burners, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to improvements in Bunsen burners for incandescent illuminating` purposes; and the specific objects are to provide means for engagement for the gas-supply valve and its seat in which a plural number of cylindrical surfaces of varying diameter on the adjacent parts serve to increase the check upon the back action of the gas under pressure and further serve to increase the stability of the valve.
A further object is to provide a more rigid and therefore more elicient form of burner throughout.
I accomplish these objects by means of a cylindrical valve-seat having a plurality of diameters secured to the burner-shell below the air-admission openings and a crown or cap valve fitting closely thereon and having` a plurality of internal diameters corresponding with the diameters of the valve-seat.
My invention consists, further, in the adjustment of the valve-crownupon the inner surface of a coupling-sleeve secured to the burner-shell or commingling-ehamber and in the specific details of construction, as hereinafter described, shown in the accompanying drawings, and particularized in the claims.
, In the accompanying drawings, Figure 1 is a side elevation of the device. Fig. 2 is a vertical central section of the device.
In these views, l is the commingling-tube, provided with the lateral openings 2. The lower end of this tube is inserted in the cou pling-sleeve 3, centrally upon which is extended the cylindrical valve-seat 4, having two diameters 5 and 6. This valve-seat is centrally perforated at 7 nearly to the top. This is pointed at 8, and, lateral openings 9 extend through the seat below the pointed extremity to the inner perforation. The central perforation is enlarged atl() and internally threaded for attachment to the gas-pipe 11.
The crownv or cap l2 is fitted closely over the valve-seat and is provided with a conical termination 13 toits inner opening 111-, which fits over the pointed end of the seat. The
central perforation permits the gas to flow into the commingling-chamber. As shown, the cap is provided with cylindrical inner surfaces of two diameters, corresponding to the surfaces of the seat, thus affording double protection from leakage of gas. The cap is adjusted by means of the eXteriorly-threaded lower edge l5, which engages the screwthreaded inner surface of the shell at I6. The exterior edge of the cap is knurled at 17 to afford a purchase for a pointed tool introduced through the openings 1S in the shell of the sleeve 3. lhe point of a knife or leadpencil could be used for this purpose. It will be seen that with two surfaces for the engagement of the cap with the valve-seat and with the screw-threaded connection with the shell the cap is rigidly supported in place, and the entire lower portion of the burner is strengthened and bound together. The commingling-tube will be seen to be threaded at 19 at its lower end, so as to be directly screwed into the top of the sleeve 3.
I believe this invention to be a great improvement in practicability and efliciency over the past art, since I avoid the objectionable features of a screw-threaded connection on the inside of the valve, which is more or less insecure and liable to leak through the grooves of the screw-thread and is never a gas-tight lit. This form of construction often entails the use of white lead or other luting material to close the apertures. Y
In my construction the screw -threaded means for attaching the valve are on its eX- terior and provide exterior means for adjustment, and the valve is provided with double interior closely-iitting surfaces which are gastight under pressure and give large bearingsurfaces for support of the valve, so that it will always be iirm and durable in use.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. In a Bunsen burner, in combination, a burner tube or shell, provided with air-admission openings, a sleeve-coupling in which the lower end of the burner-tube is inserted, a cylindrical valve-seat centrally placed thereon having a plurality of diameters and provided with a pointed top and a central gas-passage leading nearly to the top, and with lateral gaspassages in the top communicating with the central passage, a cylindrical cap having a corresponding plurality of internal diameters closely litting over the seat, and provided with a central conical passage, and a screw-threaded connection between said cap and sleeve, substantially as described.
2. In a Bumsen burner, the combination with a burner-shell Or cOmmingling-chamber, of a couplingsleeve therefor, provided with a lower threaded aperture for the gas-pipe, and an annular upper portion provided with lateral openings, a cylindrical valve-seat having a plurality of diameters and situated in said coupling-sleeve, and provided with a central aperture closed at the upper end, and communicating at the lower end with the lower aperture for the gas-pipe, and also provided with a conical top and with lateral apertures, a cap-valve eXteriOrly screw-threaded for vertical adjustment upon the interior surface of the said sleeve, and provided with an inner Opening havinga pluralityT of diameters adapted to correspond with the cylindrical surfaces of the valve-seat, and with a central orilice at the top, substantially as described.
3. TheV combination in a Bunsen burner, of a valve-seat and valve-cap therefor, and eX- terior means for support and adjustment for said valve-cap, said cap and valve-seat being provided with gas-tight engaging surfaces comprising smooth cylindrical surfaces of a plurality of diameters, for the valve-seat, and a corresponding plurality of smooth cylindrical inner surfaces for the valve-cap, said surfaces in the seat and cap adapted tO fit closely upon each other, substantially as described.
4. l na Bunsen burner,the combination with a cylindrical valve-seat, having a plurality of smooth cylindrical surfaces of different diameters, of a cap-valvethereon having a corresponding number of smooth cylindrical inner surfaces adapted to engage closely the cylindrical surfaces of the valve-seat, substantially as described.
In testimony whereof I hereunto set my hand this 20th day Of October, 1904.
