XVILIJIAM F. FOLMER, OF NEIV YORK, Y., ASSIGNOR OF ONE-HALF TO VALTER E. SCHVIN G, OF SAME PLACE.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent N o. 419,651, dated January 21, 1890.

Application filed March 23, 1889.

T0 all whom t may concern:

Be it known that I, IVILLIAM F. FOLMER, of New York, in the county and State York, have invented a certain new and useful Improvement in Gas-l3urners, of which is a specification.

I will describe a gas-burner embodying` my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure lis a side view of a gas-burner embodying my Fig. 2 is another side view at right angles to the side view, Fig. l. Fig. 3 is a central vertical section of the gas-burner. Fig. 4 is a plan or top view of a holder for a globe comprised in the gas-burner. Fig. 5 is a vertical section of the globe and globe-holder. Fig. G is a detail, partly in section, showing a eireumferential groove in the plug.

Similar letters of reference designate corresponding parts in all the iigures.

A designates the body of the burner. It may beV of cast :metal and of the usual or any other suitable shape. At the lower end it is provided, as usual, with an internally-screwthreaded socket a, suitable for engaging with At the upper end there is an internally-screw-threaded socket a', in which a pillar or tip piece B may be secured.

C designates a tapering plug fitting in a tapering cavity a2, that extends transversely through the body A. At the smaller'end of this plug there is a cylindric portion c. This extends within a cylindric cavity a3, which is formed in the body A. A spring D (here shown as-of helical form) tits within the cavity a3. At the extremity of the smaller end of- -the plug' C a lever E is secured. The spring D bears at one end against the back of the cavity a3 and at the other end against the opposite side of the lever. It therefore tends to force the lever away from the body A to draw the tapering plug C into the tapering cavity c2 of the body A. Thus it will tend to secure a tight tit of the plug in the body and obviate leakage. The lever E may be sein any suitable manner.` For instance, it may be :fitted upon a polygo` nalV base provided on the smallY end ofthe of New` Serial No. 304,436. (No model.)

plug, so as to interlock vwith the plug, and it maybe secured in engagement with said base by means ot' a screw d, passing through a hole in the lever and entering a tapped hole in the plug. It lwill be observed that the lever is not straight from end to end, but that on each side of its middle portion it is bent rearwardly at an angle, and then again bent parallel to the main portion.l This is advantageous for the proper coaction of the lever with other parts. The end portions ot' the lever are shown as provided with pendent chains 'D'. These facilitate the oscillation of the lever to effect the turning of the plug.

It will be seen that the body A has beneath the cavity a2 two independent vertical duets or gasways a4 a5. These may be of the same size. They extend from the socket a to the cavityc The Lipper part of the body A, it will be noticed, is provided with two vertical chiots or gasways a c7. One of these c is ot small diameter, and may be of the same diameter as the duet a4. It is in line with the duct a4. The other duct a7, which is in the upper part of the body A, is of considerably larger diameter. It is shown as arranged 0pposit'e the duct a5. i

The plug C is provided with a longitudinal cavity c of suitable size. It also has two transverse ducts c4 e5, which are shown as of the same size as the ducts a4 a5 in the body A, and are arranged opposite to the same, so that when the plug is suitably turned they may be in line with said ducts a4 a5, and then will receive gas therefrom. The plug is also provided with two other transverse ducts c6 c7. The duct ci is in line with the duct c4, and communicates therewith through the cavity c. The duct c6 will communicate with the duct a of the body when the plug is properly turned, and when this happens the duct a4 will be in communication with the duct a6. The duct c7 of the plug is opposite the duct a7 of the body, and is shown as of the same size as this duct c7. It is opposite the duct c5 of the plug. Gas may pass from the duct c5 into the cavity c and into the duct c7. From the duct c7 it may liow into the duct a7. Gas will iiow from the ducts as al into the pillar and thence to the tip.

IOO

That portion of the cavity c which is in the larger end of the plug C is internally screw-threaded and has itted in it a regulating-screw c2. The end of this screw may eX- tend beyond the duct c5, if the screw be properly adjusted, and then it will stop the flow of gas through the ducts a5 e5 into the ca\ity c', while yet leaving the duct c7 free to take gas from the cavity c. The screw may be moved far enough into the cavity c to obstruct the duct ci more or less. By obstructing this duct c7 more or less it will regulate the amount of gas flowing to the pillar and tip. It may be adjusted to close the duct c7.

The plug C has a circumferential groove c3 in the saine plane as the ducts c4 c6. Owing to this, gas will be supplied to the pillar vand tip even when the plug is so turned as to adjust the ducts c4 c out of line with the ducts a4 c and the ducts c5 c7 out of line with the ducts a5 a7, for gas may, even after this ad justrnent of the ducts c4 cG c5 c7, flow from the l duct a4 around the circumferential groove c3, When the gas flows in the manner last described,the quantity will be small and suitable only for a night-light or a liamel which can be burned and thence into the duet a6.

constantly.

a8 is a regulating-screw for the duct a6, ity ting in a transverse cavity in the ybody A and extending` into the duct at'. By adjusti ing it to'more or less obstruct this duct the amount of gas passing through the latter can be regulated.

The pillar' and tip are made in one piece of sheet metal.

ception of the tip ordinarily used. Here the closed end is properly shaped to form a tip, l

the metal adjacent toy it is drawn inwardly to form an inwardly-projecting bead b, and a slit b is made.

It will be seen that the main duct or gasway 61,7 will be supplied with gas by the two ducts or gasways a4 0,5 and the cavity c.

G designates a globe-holder. It is shown as consisting of a circular disk of metal having the edge g upturned to form a iange and an upwardly-extending bead formed in it near the edge. At the center it has an upturned corrugated cylinder g5 `for fitting upon the pillar B. This will slide easily upon the pillar and at the same time allow of nelydivided currents of air passing up around the pillar. I have shown the disk as having a number of V-shaped` slits g2 made in it.

VThe metal within these slits is upturned` This effects an economy. Or- 2 dinarily sheet metal is drawn up to forni the pillar and the closed end is cut out and then thrown away to afford an opening for the rei is connected to the lever is longitudinally slotted for a distance, so that the lever may inove a short distance withoutl raising or lowerin g the globe-holder.

The globe I is made out of a dome-shaped piece of sheet metal having a central opening t' at the apex and a number of strips or uprights t" extending downwardly from. the saine and serving to support it. The extremities of these strips i iit in slots g3 arranged in the edge of the globe-holder. One of the strips` t" is bent to form arearwardly-extenf'led hook i?. This will first be inserted in the slot g3 of the globe-holder. The opposite strip t" is provided with a projection t3. Vhen the globe is rocked downwardly after the engagement of the hook i2 with the globe-holder, the opposite strip will pass into its slot in the globe-holder until the projection i3 has passed beyond it, whereupon it will fasten it to the globe. The sides of the globe are tted with a cylinder of glass or mica. This may be secured at the upper edgeby forming V-'shaped slits 114 in the globe, pressing inwardly the metal within these slits to form prongs or clips and then bending these prongs or clips tightly against the glass or mica. I have shown in the upper part of the globe a number of V-shaped slips The metal within these slits will be bent slightly outward to permit of the passage of air.
