SPECIFICATION forming part of Letters Patent No. 436,093, dated September 9, 1890.
Application filed April4, 1889. Serial No. 305,941. (No model.) C
To all whom it may concern.'
Be it known that I, LEWIS J. Arwoon, of Waterbury,in the county of New Haven and State of Connecticut, have invented an Improvement in Argand Lamps, of which the following is a specification.
Argand lamps have heretofore been made use of in which the reservoir is supported by a cylinder of metal with an ornamental porcelain exterior and a base or foot, the parts being` held together by screws, and the air for the interior of the flame passing in through the ornamental base, and in other instances an ornamental supporting-base has been made use of and the atmosphere has been admitted into an annular space around the Wick-tube, extending down to the bottom of the central air-tube and within the fountain or reservoir.
The object of my present invention is to make an Argand lamp and its reservoir' in such a manner as to be adapted to set Within and be supported by an ornamental vitrified vase, such vase being closed at the bottom, so that any oil that may drip from the reservoir of the lamp or from the central air-tube may be received into such vitreous vase and effectuallykept from the table or other support for the lamp, and hence this vase can be made use of for other purposes when not required for the lamp; and in order to regulate more effectually the air which passes into the central air-tube the supply is preferably taken through the opening between the top edge of the vase and the metal of the reservoir, and I also construct the central air-tubein such a manner that any oil passing off from the wick will be returned in the reservoir, and I provide a double foraminous skirt. to the deflector above the air-tube for the purpose of more effectually preventing the lamp being influenced by external drafts of air.
In the drawings, Figure l is a vertical section of my improved lamp. Fig. 2 is a detached view of the locking device for uniting the Wick-tube housing to the top of the reservoir. Fig. 3 is a detached plan View 0f the Fig. 4 is a horizontal section of the The reservoir or fount A is of metal, having a projecting and preferably downwardlycurved flange B, adapted to set over the top of the vase C. This vase is of suitable size and more or less ornamental in its character, and in order to raise the fountain, so that the atmosphere may pass above the top of the vase and between the same and the projecting and downwardly-curved flange B, I make use of the hangers D, in the form of sheetmetal springs or lugs riveted or soldered to the exterior of the reservoir and bent outwardly within the projecting flange B, so as to rest upon the top edge of the vase C and support the fountand. leave a proper Width of opening for the admission of air, as indicated by the arrows, Fig. l. If desired, openings may be made in the vase C of any suitable charactersuch as indicated by the holes at 3-or the top of the vase may be corrugated or scalloped, as indicated by dotted lines in Fig. l.
When the hangers D are made as springs, as
shown in Fig l, they can yield to inequalities inthe internal diameter of the top of the vase.
There is a central opening through the bottom of the reservoir A, and the central airtube E is fastened to the bottom of this reservoir, and in order to strengthen the fastening and more effectually hold lthe central air-tube in its correctposition I place around the lower part of this central air-tube a conical brace 4, having its upper end soldered or brazed firmly to the outside of the air-tube and its lower edge resting upon the upper surface of the "reservoir-bottom, and this central airtube is passed through the opening in the bottom of the reservoir and is soldered firmly into its place. This conical base stiffens the air-tube, and it also serves to defiect outwardly the lower end of the cylindrical Wick, such Wick being split at its lower end and of sufficient length to reach to the bottom of the reservoir when the cylindrical portion ofthe Wick has been considerably burned or consumed. The bottom of the reservoir is corrugated radially, so that air may pass to the central air-tube when the reservoir may have. been lifted out of the vase and set upon a table 0r other support.
The top end of the air-tube E is contracted to IOC vof the tube 7.
form a cylinder havinga support 6 for the defiector or flame-spreader, and there is a short tube 7 slipped upon the outside of the air-tube Eand firmly fastened thereto at the osetS between the smaller and larger parts of the airtube, so that this short tube 7 forms the upper end of the tube around which the wick F is placed, and there is an oil-receptacle 9 between the upper end of the air-tube and the short tube 7, so that any oil flowing over the top of the tube 7from the Wick may pass into the receptacle 9 and return into the reservoir through a hole at10, and through the lower part By this construction a very strong and reliable connection is made between the air-tube E and a short tube 7 withinthe wick F, and the upper end of the airtube being cylindrical and at the sameheight as the top of the wick-tube K, or nearly so, the oil-receptacle 9 is deep and cylindrical, and there is no risk of overflow from capillary action, and such receptacle 9 is also adapted to receive within it the lower end of the cylindrical skirt 11. This ai r-tube E forms at its upper end a support to the foraminous skirt 11 of the flame spreader or deflector G. This foraminous skirt and flame-spreader have heretofore been made use of by me in Argand lamp-burners; but in lamps having a large cylindrical wick I have found difficulty in regulating the amount of air passing inside the iame so perfectly as to prevent the flame being influenced by external currents of air. To avoid this difficulty, I make use of an internal foraminous skirt l2, hanging from the dame-spreader Gand passing down inside of the central air-tube E. I find that this internal foraminous skirt does not materially obstruct the air passing up the central airtube E to the flame; but it serves to check any sudden action of the air induced by external drafts, and hence the dame is much more steady, and smoking is avoided. rIhere may be a second internal foraminous han ging skirt, as indicated by dotted lines, if so de- Sired.
There is an ornamental top I-I to the reservoir A, the central opening in which is considerably larger than the air-tube E, in order that there may be sufficient room for the insertion or removal of the wick F, the wickraising cylinder I, and the Wick-tube K out.- side of such cylinder I, and there is around the wick-tube K a collar or housing L, the lower edge of which is a flanged cylinder having at one or two places inwardly-projecting teats 13, adapted to pass down into the vertical grooves ll in the central cylindrical portion of the ornamental top H of the reservoir, and in this central portion there are horizontal depressions or slots 15, so that the collar or housing L and the parts connected therewith are firmly held upon the top of the reservoir by giving to the collar and Wick-tube a partial rotary movement to bring the teats 13` into such slots 15, and the parts can be disconnected by the reverse motion.
The Wick-raising pinion is represented at M, and a movable foraminous air-distributer N surrounds the wick-tube K, and at O are the chimney-holding springs, and a second air-distributor S, which is conical, surrounds the wick-tube near the upperend and within the base of the chimney.
I claim as my invention- 1. The combination, with a supportingvase, of an Argand lamp-reservoir having a central air-tube opening through the bottom of the reservoir and an outwardly-projecting ange at the top end of the vase, and hangers resting upon the top edge of the vase and between the same and the flange of the reservoir, substantially as set forth.
2. The combination, with the Argand lampreservoir having a central air-tube opening through the bottom and outwardly-proj ecting supports around such reservoir, of a vase having a closed bottom and on which the vase stands, the base being higher and larger in internal diameter than the reservoir to leave a space between the vase and reservoir for the passage of air to the central air-tube of the burner, substantially as specified.
3. The combination, with the Argand lampreservoir A, of the central air-tube E, securely fastened to the bottom of the reservoir at the central opening therein and the conical brace surrounding the air-tube and fastened thereto and resting upon the upper surface of the reservoir-bottom, substantially as set forth.
4. In an Argand lamp, the central air-tube, the upper end of which is on a level, or nearly so, with the top of the exterior wick-tube and cylindrical and of a smaller diameter than the lower part of such air-tube, there being an offset between the larger and smaller parts of the air-tube, in combination with the short tube 7, corresponding in diameter with the lower portion of the air-tube and fastened at its lower end atthe oset, there being an opening to allow oil to pass back to the wick from the annular oil-receptacle, substantially as specified.
5. Thecombinatiomwiththecentralair-tube E in an Argandlamp, of the flame-spreader G and two hanging foraminous skirts, onewithin the other and connected With such flamespreader,substantially as set forth.
6. The combination, with the vase and the Argand lamp-reservoir, of springs fastened to the reservoir and forming hangers for the reservoir, substantially as set forth.
