SPECIFICATION forming part of Letters Patent No. 497,605, dated May 16, 1893. Application filed April 28, 1892. Serial No. 430.993. (No model.) Patented in Belgium May 16, 1892, No. 99,7482.

To @ZZ whom it may concern.-

Be it known that I, FRANK RHIND, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and usefulImprovementsinLamp-Burners, (for which I have received Belgian' Letters Patent No. 99,482, dated May 16, 1892); and I do hereby declare the following to be a full, clear, and

lIo

exact description of the invention, such as will enable others skilled in the art to'which it appertains to make and use the same.

This invention relates to certain novel and useful improvements inlamp burners and has.. for its objects, first, to provide a burner of novel construction; second, to provide an improved form of extinguisher whichl shall be readily removable from and replaceable upon the wick tubes; and third,\to improve upon the construction of the detlectorfso that its .strength and stiffness will be enhanced, and

perfectly smooth edges formed upon the llame slots; and with these ends in view my inven-- :tion consists and resides in the several lconings which form a part of' this specification,

and' in whicht Figure 1, is a vertical section through a lamp burner constructed in accordance with my invention, the 'extinguisher beingshown in its normal position.

Fig. 2, is a similar View with the extinguisher raised. Fig. 3, is a similar section, but showing a triplex burn'- er, the parts being in the same position as those shown at Fig. 1. Fig. 4', is a detail section at right angles tothe previous figures, showing the lift and its operating lever. Fig.

5, is a detail plan view of the duplex ext-in-y guisher removed from the lamp. Fig. 6, shows in plan view a section of metal adapted to form the deiiector, the lflame slots being cut vbut not bent. Fig. 7, shows in section a slight modification of the triplex extinguisher. Figs. 8 and 9, show in plan view and detached the' forms of triplex extinguisher shown respectively in Figs. 7 and 3. Fig. 10, is a detail end elevation of Fig. 9. Fig. 11, is a detail plan view of the lifting lever for the triplex extinguisher. Fig. '12, is a'deta'il plan view showing the means of attachment betweenl the'top portion of the burner and the'air distributer. Fig. 13, shows in detail elevation one of the slots adapted to operate as shown 6o` at Fig. 12.

The same numerals denote the same parts v in each of the lfigures. n

- 1 denotes the burner vbase through which extend the wick tubes 2 and which at its lower 65 end is provided with screw threads 3for its attachment to thelamp collar. In this basel are journaled shafts or spindles 4 upon which are mounted the serrated wick-lifting wheels 5 whose'peripheries engage and operate the 7owicks through slots inthe wick tubes.

6 is a perforated distributer in the form of a plate or cap whichvmay be supported above the burner base upon legs or pillars, but which may equally aswell, as is shown,'be securedr 75 l upon the wick tubes themselves. This distributer is provided with an annular bead 7 above which, as appears at Fig. 12, are locking studs 8 of any required number. Below 4the bead 7 and onLthe extreme 'edge of the 8o part is a second bead 9, the spacev between these beads formingla seat for a shade-holder 10, a small portion/of which is shown at Fig. 2.

11 is the deflector or flame dome and vupon this is supportedl the annular chimney gallery 12. The iiame s lots in thisdome I prefer to make by cutting openings in the metal of the general shape shown at '13, Fig. 6, and then bending the edges of these openings down'-v ward at right angles, as for instance by a 9o force-punch, so that they form depending lips 14, as isv particularly shown at Figs. l and The presence of these lips insures'a flame slot with a perfectly smooth edge and they greatly stiftenthe deliector; and it may therefore be made of very lthin metal without unnecessarilyreducingits rigidity. Below the chimney7 gallery are formed air inlet perforations 15 and inside the deiiector is acircular vertical distributer'l for the equalization of the draft roo entering through the holes 15.

17 is a square sleeve or housing shown in plan view at Fig. 5 and in section at Figs. 1 and 2. This sleeve surrounds the wick tubes and isfree to slide vertically thereon and may be removed therefrom entirely by simply lifting it off, thereby permitting the wick tubes and the extinguisher itself to be readily cleaned, or if the extinguisher becomes broken a new one may be substituted in a moment. In this sleeve is journaled a pair of extinguishing wings or blades 18. Each of these blades is provided with longitudinal stiening ribs 19 and at each end is a bearing 2O whose shape is that of a segment of a circle. These bearings project through and are held in slots 21 formed in the ends of the sleeve, said slots being curved and of the same radius as the bearings, but slightly longer,where by the blades may have a free swinging movement,but nolateral movement or free sidewise play. Each of the wings is also provided with a curved and downwardly extended tail 22. These tails are quite close together, as shown at Figs. l and 2, and immediately beneath them is a lift 23 whose upper face engages both tails and whose shank in its turn is engaged by means of a lever 24 journaled in the burner base, in which last named part the lift 23 has a bearing and is adapted to slide vertically.

The extinguisher for the triplex burner is similar to that for the duplex in all essential particulars, but I make it in two ways. As shown at Figs. 3 and 9, the sleeve has journaled therein wings 18 which operate upon the outside wicks, and another pair of co-operating wings 25 similar in all respects to the wings 18 andv adapted to operate upon the central wick tube. As a variation upon this I sometimes use only one central wing 25, arranging it to operate against the edge of a cross brace or bar 26 in the same manner as the wings 18 operate against the edges of the sleeve. This is shown at Figs. 7 and 8. In the triplex burner I use two lifters 23 whose operation is in no wise changed, and I actuate these by means of a bifurcated lever 27 shown in detail at Fig. 11. In fastening the removable part of the burner, namely the deiiector and its attached parts, upon the distributor 6, I use in connection with the studs 8 shown at Fig. 12, a novel form of locking slot 28. The lower end of this slot is oblique and when it comes in contact with the stud and the movable part is rotated slightly it rides downward upon the stud until the latter enters the horizontal portion of the slot which constitutes its upper end.

In the operation of my invention when the lift 23is raised by means of the lever it carries upward with it the sleeve 17 and the parts thereunto attached until the top of the sleeve comes in contact with the under side of the deflector,`thereby limiting its upward movement. The continued pressure of the lifter upon the wings then rocks them upon their bearings, throwing them outward against the sides of the sleeve, as appears at Fig. 2, thereby extinguishing the lights from both wicks. Upon the release of the lever 24 the lifter and the frame fall back by gravity from the position shown at Fig. 2 to that shown at Fig. 1, the wings being swung backward to their normal position by their sliding contact with the surfaces of the wick tubes. The operation of the triplex extinguisher is precisely the same, and it is capable of immediate removal for purposes of cleaning, repair and the like. By mounting the distributer cap above and clear of the burner base I iind that the air circulation about the tubes is very perfect and keeps said tubes cool, which is decidedly advantageous.

It will be observed that I do not make use of any spring or similar device for the move ment of the wings, this being accomplished by the upward movement of the lifter, and

this is one of the important features of my invention inasmuch as the parts will all return by gravity to their original positions when the lever 24 is released. Furthermore itwill be observed that there is no connection between any of the parts forming the extinguisher and the lifter so "that the sleeve and all the pieces connected therewith may be at any time removed. When the flame dome with its attached parts is lifted and the extinguisher removed the top of the distributer cap is exposed and may be cleaned with great facility, as may also the wick tubes,
