y IMPROVEMENT IN REGULATING- DEVICE FOR GAS-BURNERS.

The Schedule referred to in thele Letters Patent and makingpart of the same .of reference` marked thereon.

AThe principle and nature of my invention consist in supplying gas-fixtures with a device whereby, when properly adjusted, it is rendered impossible to shut off the gas and extinguish the flame. and light entirely without a readjustment o f the device; but which ajdjustment and readjustment are at the will and under the command of the operator.

Of the drawings- Figure l is a perspective view of the main body or center piece -of `a gasdixture, showing the extemal parts of my inventionin place.

Figure 2 is a vertical section of thesame thing showing a longitudinal section of the parts of my invention as employed in operating the same.

Of fig. 2, a c a a is the main body of the fixture, shown with a cavity or hollow, g g.

b is the threaded opening for the supply or induction-pipe. Y

c c are the threaded openings for the. eduction or burning-pipes. y e e is a hollow cylinder screwed into the main of the fixture. at d d.

The hollow o r bore of this cylinder should be coarsely screw-threaded at point d d for the distance of half to three-fourthsfof an inch to correspond with threads on tubes f.l l

Tube f is a tube which passes longitudinally throughv hollow cylinders d d, and across cavity g g of the mainA body of the xtnre to the top of that cavity, so as to close the opening-.to induction-pipe b when desired. This tube terminates interiorly, in an archedor hemisphencatV nipple screwed upon the end.

A short distance ybelow this nipple a flange or shoulbody ,der is formed on the tube f, on which is to rest and be secured in place by the nipple Aan elastic packingn'ng, as shown at i z'.

Letters jj indicate-a mere stuiiing-box to be screwed i on to hollow cylinder d d for packing-tube f gas-.tight The letters k k mark mere projections or handles on and near the outward end oi' tube f for convenience in working it. A

For the fourth or third of an inch outward from these projections tube f has a screw-threaded extension, as shown at l l.

The hollow or bore of tube f is not uniform in caliber throughout. From h, at the apex of the nipple,

to the apex of the conical enlargement of the bore at fm, the caliber need not exceed one-sixteenth of an inch for four burners.

From m the caliber is conically enlarged, as shown at that point, to the size of about one-fifth of an inch, and is thence continued of that size throughout the remainder of the tube.

A short distance below the base of the conical enlargement of tube f the wall of the tube is' pierced with Vsmall holes or gas-ports, corresponding in 'number with the number of eduction or burning-tubes, as shown aten n 7L. y

This tube is screwed into the main body ofthe x` ture at d d. y

Its outward extremity is provided with a stuingbox, o o, for packing regulator p, as shown between l and o. I

Regulator p is a mere cylindrical rod of sucient length and size to occupy and fill the enlarged portion of the bore of tube j, and extend suicient1youtward to be operated by the thumb and linger, and having its outward extremity provided with a thumbpiece, as shown at q.

It is secured andworked within' tube- `f'by means of a screw-thread working in a corresponding thread in stuiing-box o, as shown at o o, and is to have a longitudinal movement in operation, from its position as shown in fig. 2, to point m in the same gure.

Its upper or inward extremity1 is obtusely conical to correspond with.' and closely tit, when screwed home to m, the conical enlargement inthe bore of tube f.

My invention is more particularly applicable and useful in the lighting of billiard tables', where thegas is to be alternately let on at full head and partially cut oi. l

. To operate my invention and produce its intended effect, the gas is let on by so turning tube f as to withdraw the arch of its nipple or inner end from the inner opening of induction pipe b, and the packed shoulder t' from the corresponding seat 7' `on lthe inner surface of cavity g. v

- The gas will then flow into cavity g and through pipes c to the burners, Where it is to be lighted in the usual manner. The gas will-now burn with a full or maximum flame, and give full light.

This it will continue to do, to a great extent, though tube f be again screwed home to h so long as regulator p occupies the position it does in fig. 2, for the gas will still flow into cavity g through the smaller bore of fand the holes or gas-ports n.

But if,`by means of thumb-'piece q, regulator .p is now screwed inward until the base of its conical point partially closes ports n'the supply of gas to the burners (and consequently the flames).l will be diminished. By this means any degree of .diminution of the gas and dames may be attained, or the gas may be entirely shut o, and the flame. extinguished. But when, by means of regulator p, the flames are reduced to the size at which they are to burn when not used for light,l then the device may be termed set for the time being. When in this condition if tube f be again withdrawn from h a full dame and light will be instantly restored. But by screwing it home to h again the flame and light will not and cannot be extinguished, but the flame will be instantly restored to lits regulated minimum size, and this without danger of extinguishment, how quickly soever the'operation may be performed. To extinguish the ame regulator p must be screwed home to m, or at least so far as to wholly close gasports n.

What Iclaim as my invention, and desire to secure by Letters Patent, is-

1. A regulating device 'or cock to be applied to gas- HENRY scHLfrz.
