JOHN KIRSCHBAUM, OF WATERBURY, CONNECTICUT, ASSIGNOB, TO WATERBURY MFG.

CO.', OF WATERBURY, CONNECTICUT, A CORPORATION;

INVERTED inoAivnnsonnr GAS-BURNER.

Specification of Letters Patent.

Application filed December 28, 1917. Serial No. 209,205.

To all whom it may concern:

Be it known that I, JOHN KIRso BAUM, a citizen of the United States, residing at WVaterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Inverted Incandescent Gas-Burners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in I Figure 1 a view in side elevation of an inverted incandescent gas-burner constructed in accordance with my invention.

Fig. 2 an enlarged view in transverse section on the line 2-2 of Fig. 1.

Fig. 3 a detached broken view partly in elevation, and partly in vertical section, showing the inner end of the goose-neck, and the bearing-sleeve.

Fig. 4 a detached view in elevation of the bearing-s1eeve.

Fig. 5 a detached view of the inner end of the goose-neck.

Fig. 6 a detached edge view of the disklike gas-check prior to its insertion into the bearing-sleeve.

My invention relates to an improved inverted incandescent gas-burner, the object being to provide a simple, convenient and effective fixture of the character described.

IVith these ends in view, my invention consists in an inverted incandescent gasburner having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, the goose neck 3 is formed at its inner end with a straight trunnion 4 provided with three equi-distant, oblong, axially arranged, rectangular air-ports 5 which co-act with three complementary air-ports 6 in an upstanding bearing-sleeve 7 formed upon its lower end with an integral concentric annular bead 8 from which an integral concentric, internally threaded mounting or conpling-nipple 9 depends. The difference in diameter between the bearing-sleeve 7 and the coupling-nipple 9 results in the production of a horizontal bearing-shoulder 10 for the support of a disk-like gas-check 11 having a central perforation 12 and initially produced in concavo convex form, as shown in Fig. 6, to adapt it to be passed downward through the sleeve 7 so as to rest upon the shoulder 10 after which it is flattened so as to increase its diameter, and cause it to fit snugly within the bead 8. The trunnion 4 aforesaid, fits into the sleeve 7 with an airtight friction fit. By swinging the gooseneck to the right or to the left, the ports 5 and 6 co-act to regulate the amount of air admitted into it. As shown, the goose-neck is provided at its threaded outer end 13, which is parallel with its trunnion 4, with a shade-holder comprising three arms 14: supporting a shade 15 inclosing a mantle 16. My improved goose-neck burner is mounted upon an ordinary gas-fixture 17 upon which the coupling-sleeve 10 is screwed.

I claim 1. In an inverted incandescent gas burner, the combination with a swinging goose-neck provided at its inner end with a trunnion having one or more air ports, of a normally stationary upstanding bearing-sleeve receiving the said trunnion with a friction fit and having one or more complementary air-ports which are opened and closed by the rotation within the said sleeve of the said trunnion due to swinging the said goose-neck, and the said sleeve being provided with a depending couplingnipple, and a gas-check interposed between the said sleeve and nipple.

2. In an inverted incandescent gas burner, the combination with a swinging goose-neck provided at its inner end with a trunnion having one or more air-ports; of an upstanding bearing-sleeve receiving the said trunnion with a friction fit and provided with air-ports complementing the air-ports Patented Nov. 5, 1918.

thereof, the said sleeve being formed at its In testimony whereof, I have signed this lower end with a concentric annular bead specificatlon 1n the presence of two subser1b- 10 for the reception of a gas-cheek, and the said 111g wltnesses.

bead bein formed with a depending internally th readed coupling-nipple smaller in JOHN KIRSOHBAUM' diameter than the said sleeve for the produc- Witnesses:

tion of a bearing-shoulder upon Which the A. C. BECKER,

gas-check rests. J. S. NEAGLE.
