UNITED S'A'rEs PATENT OFFICE.
DAVID MCGARTY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF A PART OF HIS RIGHT TO ELWOOD A. COLLIN S AND JOHN H. LEWARS, OF SAME PLACE.
IMPROVEMENTIN L AMPS FOR BURNING HYDROCARBQN OILS, &c.
Specification forming part of Letters Patent No. 189,246, dated April 3, 1877; application iiled January '30, 1877.
To all whom it may concer/n Be it known that I, DAVID MGGARTY, of Philadelphia, Pennsylvania, have in-vented certain Improvements in Safety-Valves for Lamps, of which the following is a specification:
This invention relates to that class of lamps in which the collar to which the burner is attached is provided with an opening covered by a pivoted valve, for the purpose of admitting the escape of explosive gases, when the same become charged in the lamp-fount, thereby preventing the breakage of the lamp, and the danger attendant upon the explosion of the gases.
My invention consists in providing the periphery of the lamp-collar with an opening, and combining therewith a thumb-valve, pivoted longitudinally on, and parallel with, the lamp-collar, and providing said thumb-valve with a spring, arranged between the rear end ofthe valve and the lamp-collar,- in such manner that the rapid escape of the gases, in case of explosion, is permitted by the same opening the valve, the latter being automatically closed by the spring; and, moreover, the valve is provided with a rearwardlyprojecting thumb-piece, by which the valve can be operated by hand, all of which will be fully hereinatter described.
In the accompanying drawings, Figure 1 represents a perspective view of a lamp-collar having my improved valve, and applied to a lamp. Fig. 2 is a central sectional view 5 andA Fig. 3, a top view, partly in section, showing the application of the valve.
The letter A represents the body of the lamp, which may be constructed of glass, or any other material ordinarily used for such purposes. B represents the ordinary annular collar, which is cemented to the lamp-fount,
and is provided with a screw-thread for the application of the burner, as ordinarily. The periphery of this collar is provided with an aperture, C, and also with two lugs, a a, near the same, between which is pivoted the safetyvalve, said valve, when in position, lying longitudinally along, and parallel with, the lampcollar. The forward end, b, of the valve is provided with the packing D, forming the valve proper, and it sits immediately over the opening, while the rearwardly-projecting end c forms a thumb-piece, by which the valve can be operated by hand; but in order to keep the Valve shut, and automatically close the same when open, I arrange between the collar G and the thumb-piece c a spring, E, of any preferred construction.
It will be seen from the foregoing description that the ready escape of gases, in case of an explosion, is permitted; that the'valve can 'be lconveniently operated by the thumb; and,
moreover, the spring is a positive means of automatically closing the valve when opened, and retains the valve in position on its seat in a yielding manner, which is not the case where a simple gravitating-valve is pivoted at its top edge to the lamp-collar, although such construction will, of course, permit the escape of gases in case of an explosion.
What I claim, and desire to secure by Letters Patent, is
The combinatiorn'with a lamp-collar having an opening in its periphery, of a valve, D, pivoted between the lugs a a, longitudinally of, and parallel with, the vertical wall of the said collar, and provided with a rearwardlyprojecting thumb-piece, c, and a spring, E, secured between said thumb-piece and the lamp-collar, substantially as and for the'purpose described.
In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.
DAVID MGOARTY.
