RUFUS S. MERRILL, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN LAMP-BURNERS.
Specification forming part of Letters Patent No. 118,824, dated July 1S, 1865.
To all whom it may concern:
Be itknown that LRUFUs SPAULDING MER- RILL, of Boston, in the county of Suffolk and State ot' Massachusetts, have invented certain new and useful Improvements in Lamp-Burners; and I hereby declare that the followingis a full, clear, and exact description ofthe same, reference being had to the accom pan yin g drawings, in which- Figure 1 is an elevation, Fig. 2 a plan view, and Fig. 3 a section through the center line, of my improved burner. Fig. 4 are detail views, partlyin section and partly in plan, ot' its component parts.
Heretofore the flame ot` burners provided with annular collectingchambers could not be regulated without adjusting the wick in its tube or holder, so as to allow it more or less to project from above the tip, and this could be effected with safety only by first extinguishing the flame and by then trimming down or drawing out the wick. To obviate this Ihave rendered the eolleeting-ehambers adj nstable upon the wick-tube as to height, thus contracting or expandingthe tlame, as the case may he. Iliasmuch as these burners are made of thin metalhigh conductors of heat-it would beimpossible to effect the adjustment without allowing the burnerirst to cool down, or without some means which would protect the ngers from burns. To remedy this I mount the annular collecting-chamber upon a concentric jacket open at its lower end, but secured at its upper end to a friction-sleeve sliding on the wick-tube. The jacket, being open below, will allow the air to rise and circulate in the space surrounding the wick-tube. For further protection otl the iingers, and to facilitate the operation of adjusting, I provide thejacket with a disk, the outer rim of which is kept cool by means of a close circular series of holes.
To enable others to make and use my invention, I shall now proceed to describe the construction and arrangement of the parts and operation of my improved burner.
Referring to the said drawings, a is the cap of the vessel which contains the uid to be burned. It is composed-ot' a metal disk havin g an annular liange, b, provided with a screwthread, whereby the cap is secured or screwed on to the collar of the vessel. The disk is milled at its circumference, or covered with another disk of thin metal of a diameter somewhat larger than that of the disk, so as to allow of its outer edge being bent over and around the rim of the inner disk.
From the center of the disk a springs the wick-tube c, upon which is fitted so as to have frictional hold upon it another tube, d, somewhat shorter than the wick-tube, so as to allow of its traveling up and down around the wicktube for the purpose of reducing, or contracting, or spreading, or lengthening the portion ot' the wick protruding at the tip of the burner. To this adjustable sliding tube, and at the upper part thereof, is attached a jacket or conical sleeve, c, the upper diameter ot' which snugly fits the sliding tube, with which it is secured by one or more indentations or depressions, while its lower diameter is larger, so as to present a wide opening, through which the surrounding air is induced to enter and to circulate within the conical space of the sleeve for the purpose before mentioned.
Onto the jacket are fitted the annular collectingchambers f, which are made of three distinct pieces unitedthat is to say, of an annular disk, g, provided with an interior and exterior uprightiiange; cfa cone, h, at the base of which is a horizontal ange iitting against the exterior upright -flange of the disk g; and ot a second cone, i, larger in diameter than the former, and provided with a horizontal flange or ilare smaller than the horizontal flange of the other cone. These three parts are tted. together by first placing the cone h into the trough-like disk g, by then placing upon it the second cone, i, and by finally swaging down the exterior upright iiange of the disk onto the horizontal'tlare ofthe outer cone, t'. By means of the flanges the relative position ofthe innerl and outer cone is tirmly secured in relation to the disk. Thus the three parts are united Without the employment of any solder, and consequently without liability ot' their giving way by their exposure to heat.
In addition to the jacket, I use a circular plate, m, secured to and around the sleeve or jacket, for the more convenient handling ofthe adjustable parts of the burner. The plate I prefer to perforatc with numerous holes within its circumference, so as to break, as it were,
the conduct ot' the heat from thejacket to the circumference by means ot' air-channels, which Will necessarily establish themselves through the said holes.
From the preamble ot this specification, as well as from the description ot' the parts and thcirindividual functions, the operation ofthis invention will be readily understood. It may be Well, however, to state that the application ot the adjustable wick-tube, operating in unison with the collecting-chambers, dispenses with the necessity of any nice adjustment ofthe wick in themain tube, as is the ease in ordinary duid-burners, for it' there be .too much wick at the tip of the burner it can be reduced Without trimming it down, by simply elevating the sliding tube and collecting-chambers, and vice Versa. It' there be an insufficient amount of Wick, it may be increased by depressing the collecting-chambers.
Having now fully describfd my said invention, I claiml. The employment ot' annular concentric collecting-chambers at or near the tip of the burner, when the same are made adjustable in relation to the burner, substantially as hereinbefore set forth. A
2. The attachment of the annular collecting chamber or chambers concentrically with the wick-tube to an adjustable sliding tube or friction-sleeve, whereby theiiame ofthe burner may be regulated without interference with the Wick itselt'.
3. In combination with the above, the concentric outer jacket, open at the under side, so as to allow air entering the same in the manner and for the purpose substantially as set forth.
4t. In combination with the above, the perforated disk orange,for the purpose specified.
5. The method described ot' attaching the outer jacket to the adjustable slide by indentation, substantially as set forth.
In testimony whereof I have signed my name to this speci lieal'ion bet'ore two subscribing Witncsses.
