In this instance the top of Ioo the needle-valve 13 is provided with a seat 14, With which the housing l5 of the regulator is d'etachably connected.

The construction of the modification shown in Fig. 3 is the same as shown in Fig. 4, With the exception that the regulator 16 is placed beneath the manual needle-valve 17. The object of providing the manually-operated needle-valve below the automatic regulator in Fig. 3 or above it in Fig. 4 is that in case the automatic regulator should get out of order it is possible to detach it and apply the Bunsen tube to the manual needle-valve and in that Way insure a good light, the presence of which in many instances is essential, particularly in street-lighting.

It will be obvious to those skilled in the art to which the inventionrelates that modiiications may be made in details Without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

lHaving thus described the nature and objects of the invention, what I claim as new, and-desire to secure by Letters Patent, is-

1. Means for automatically regulating incandescent gas-lights to suit varying gaspressures which comprise the combination of a pressure-regulator having provisions for automatically adjusting the size of an opening in response to changing gas-pressure, a diaphragm having a jet-orifice of unchanging size, a single unobstructed chamber interposed between the opening and orifice, and a Bunsen tube having air-inlets at its base and unobstructed at its top and receiving a substantially uniform jet from the jet-orifice.

2. Means for automatically regulating incandescent gas-lights to suit varying gaspressures which comprise the combination of a pressure-regulator having provisions for automatically adjusting the size of an opening in response to changinggas-pressure, a single unobstructed chamber receiving regulated floW from said opening, a diaphragm having a jet-orifice of unchanging size communicating with said chamber, a Bunsen tube having air-inlets at its base and unobstructed at its top and receiving a substantially uniform jet from th'e jet-orifice, and a by-pass around the regulator, substantially as described.
