INVERTED BURNER.

Specification of Letters Patent.

To all whom it may concern Be it known that I, AnoLP -I C. BECKER, a

citizen of the United States, residing at Oakville, .in the county of Litchfield and State of Connecticut, have invented a new and useful Improvement in Inverted Burners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact'deseription of thesame, and which said drawings constitute part of this specification, and represent, in-

Figure 1 a broken view in of the upper portion constructed in accordance with my invenenlarged scale in vertical central section. Fig. 3 a. detached plan view of the domical burner cap. Fig. 1 a corresponding view of the domical shut'er. Fig. 5 view of the washer. My invention relates to an improvement in inverted burners for lamps of the mantle type, the object being to provide them at a low cost, with convenient and effective means for controlling the ingress of air into the chamber surrounding the Bunsen pipe.

With these ends in view my invention consists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim. -In carrying out my invention I employ a domical shutter 2 having a largecentral opening 3, and a concentric series of circular air-ingress slots 4 and rovided with an integral radially exten ing finger-piece 5. This shutter fits snugly within the upper portion of the domical cap 6 of the burnershell 7, the said cap being formed with a 8, and a circular series of oblong air-ingress'slots 9 corresponding in number to the slots 4 aforesaid. A horizontal slot 10 in the cap (5 provides for the outside elevation ward passage through it of the finger-piece 5 and limits the oscillating movement of the 4 shutter 2. The shutter is held in place near the upper end of the cap by means of a of an inverted bur'ner a corresponding washer 11 having a central opening 12, and held in place by the'upper end of the Bunsen tube 13 upon which it rests, the said tube being internally threaded for the receplatented Aug. 13, 1912.

tion of the threaded lower end of the center 1 tube 14 which is in effect a gas tube, and a furnished with a valve not shown, and a button 15 for regulating the same in the usual manner.

It will be understood that the threaded lower end of the tube 14 passes through the circular central opening 3 of the shutter 2, through the circular opening 8 of the domical cap (3, and through the central opening 12 of the washer 11, as clearly shown in Fig.

3. The lower end of the cap 6 sets over the upper end of the burner shell 7 as clearly 2. The upper edges of shown',in Figs. 1 and )inched' and the cap (5 and washer 11 are ;held between the upper edge 0 the pipe 13 andrthe shoulder 16 upon the tube 4 as shown in Fig. 2. The outer edge of the wasluar 11 is struck downward with respect to its horizontal upper edge. so as to conform to the pitch of the upper portion of the ca 6 and so-as to produce an annular space 1? between the washer and the upper portion of the cap 6 for the-reception of the upper edge of the shutter as clearly shown in Fig. 2, whereby the shutter is held in place and yet permitted to turn upon its. upper edge as uppn a center.
