Be it known that I, EDWARD J. KNAPP, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Sanctuaryll amps, of which the following is a specificatlon.
This invention relates to improvements in sanctuary lamps, and has for its object to provide a novel, simple, convenient and economical fixture, designed particularly for use in churches and other religious places where lamps of the class are used. A further object is to provide. a sanctuary lamp, where a candle of relatively large size and composed of a'suitable slow burning wax is employ d instead of the variousoils heretoforeused as the fuel for suchlamps. A further object is to provide novel and simple means comprising a lowconductor of heat for protecting and steadying the to of the candle and for conserving the fue of the lamp, for prolonging the lighting intervals,
as well as for preventing the waste usually attending the burning of wax-candles. A further object isto provide novel and simple means for preventing the loss or escape of the melted wax after the last of the solid candle has been reduced to oil. And a further object is to reduce the number of parts and to lessen the cost of producing lamps of the class.
The invention relates particularly to an improvement in the sanctuary lamps shown and described in my United States Patent No. 1,200,121, dated October 3, 1916.
I attain these objects by the means set forth in the detailed description which follows, and as illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section, through the complete lamp. Fig. 2 is a central vertical section; showing the transparent cap in engagement with the candle support, during the final consumption of the candle. Fig. 3 is a horizontal section, taken on line 3-3 of Fig. 2; showing the plain bearin surfaces of the cap in engagement with t e outer surface of the candle. Fig. 4 is a top plan view of the removable candle support; showing the rubber or other packing engaged by the bottom of the cap.
. In my former patent referred to, the removable support for the candle is disposed in a pan, which in turn is suspended in the hollow main base. This support is fitted with guide-rods, which extend upwardly at the opposite sides of the candle, and the top of the candle is surmounted by a heavy metal ring or cap, which is movable vertically on said guide-rods, as the candle wastes or burns away. V Theheavy metal cap referred to, follows the wasting candle until it comes to rest upon the upturned mouth of the movable support, where it remains until the last of the candle is consumed. In practice it has been found that the heavy metal cap-ring of the former patent frequently becomes canted on the guide-rods, and also the said rods sometimes become coated with the wax to such extent thatthe cap fails to descend truly and freely, as intended, and thus when the said cap makes contact with the top surface of the candle support, it fails to tightly seal the joint therebetween, and more or less of the wax-oil escapes. This occasions the frequent cleaning of the support and adjacent parts. Furthermore, the amount of melted wax which escapes, as explained. greatly shortens the lighting period and therefore increases the operating cost of the lam It is a particular object of the present invention to eliminate the heavy metal ring or weight, the guide-rods and the pan of the former device, and to substitute therefor a'transparent vitreous cap having certain peculiarities of construction, which enables the said cap to gravitate with the burning candle, without any guiding means, and when it comes to rest upon the candle support, it telescopes a rubber or similar pac ing ring carried by the support, and effectually seals the joint between the'said parts, with the result that practically every drop of the wax-oil .is consumed, thereby prolonging the lighting period many hours. The detailed description of my invention follows:
In the drawing, 2 represents the main base of the lamp, preferably hollow and made of suitable sheet metal, which is usually spun so as to present an ornamental appearance and yet be adequately strong. The bottom of thebase comprises a relatively broad circular flange 3, while the top 4 is formed cylindrical. Between the top 4.- and the bottom 3 of the base is an annular shoulder or ledge 5, and a little higher up is a larger ledge 6, which is preferably perforated at 7, for the admission of an. The
Patented Feb. 5, 19118.
. ing cavity or socket 10, in which the bottom of the candle 11 is disposed, the said cavit having an annular bevel surface 12, whic causes the melted wax, during the finalconsumption of the candle, to gravitatev into the comparatively narrow bottom space 12'. The part 9 of the support also has a circumferential flange 13. he supike base 15, which rests upon the ledge 5. A rubber or other suitable packing ring 16 is disposed around the part 9 and .has a flange 16, which corresponds to and rests upon the flange 13, as best seen in Figs. 1 and, 2. The top end of the ring 16 referably extends some distance above t e top of the part 9, and thus increases the dept and capacit of the cavit 10.
The cand e 11 is provi ed with the usual wick 11', to the lower end of which is secured a thin metal disk or part 17, which protects the lower reduced end of the candle while being handled, but mainly serves to support the wick in erect position, after the wax has all become melted, until the light finally dies out .(see Fig. 2).
In assembling the lamp ready for use, the sup ort 9 is first placed in the base 2; the
can 1e 11 is next mounted on the said sup-- port, and partially rests upon the ring 16. A cap 18, preferably made of glass or other non-metallic substance, having a lower-conductivity of heat than ordinary metal, is next mounted on top of the candle, after which a relatively large transparent cylindrical globe or part 19 (preferabl red glass), is disposed outside of the cand e, the cap, and the su port 9. The bottom end of the globe 19 te escopes into the cylindrical portion 4 of the base, and. its weight is su ported by the ledge 6, just outside of t e circle of air-holes 7. The cap 18' has a relatively large cylindrical portion 20, having a thickened lower endfor increasing its weight. The portion 20 is hollow, and at intervals around its interior, it is provided with longitudinal smooth bearing surfaces 21, whic engage and slide on the outer surface of the candle. The lower end of the part 20 preferably fits'the candle loosely, and its hollow inside tapers or diminishes 1n diameter throughout its length, as best seen in Figs. 1 and 2. The top portion of the candle is also tapered, as at 20' in Fig. 1, and preferably snugly fits into the tapering to of the part 20, when the cap is first applied. The tapering of the candle and also of the part 20, to ether with the bearings 21, all tend to ho d the cap truly concentric to the candle during t e operation of the lamp. The bearings 21 are relatively narrow, so as to offer the least resistance to the gravitation of the cap, as the candle ort 9 is joined by a narrow neck to a diskmelts away. Between the several bearings 21, the interior of the cap is fluted, as at 22, and the fluted portions referably do not contact with the sides of t e candle, except at'the portion of the candle which is tapered 20). The flutes are provided particularly or reducin the frictlon, whic otherwise would retar the gravitation of the cap. At the top of the cylindrical portion 20, the cap is contracted to provide a rather abrupt and prominent shoulder 23, which rests firmly upon the to of the candle 11, and above the annular s oulder 23 the cap flares outwardly and upwardly as at 24, for roviding a ho perike well or cup in w ich the unmelte tip 11' of the candle and the wick 11' project. The whole cap 18 is ref- .erably made of transparent materia so that the flame of the wick 11' may show through the flaring part 24. After the candle has burned for a time, the tip 11" melts or is reduced to wax-oil, and thereafter until the final consumption of the candle, the flaring cup 24 is more or less filled with melted wax, as indicated by the dotted line 25 in Fig. 1. The presence of the warm melted wax in the vicinity of the shoulder 23, tends to soften the body of the candle below that point sufficiently to allow the taperin interior of the cap to continually remo d and maintain the aforesaid taper of the candle and thereby efiectually prevents the escape of any of the melted wax from the cup 24 during the wearing away of the candle.
As the candle 11 melts and wastes away by the heat of the burnin wick, the cap 18 gravitate's with the can Is, as explained, until nearly all of the solid wax is melted. But before the final reduction of the solid candle, the lower end of the cap 18-20 reaches and telescopes the rubber ring 16, and finally comes to rest firmly seated upon the flange 16'. When these parts come together, as shown in Fig. 2, the ring 16 being tapered to corres 0nd to the sha e and size of the ca an oi -tight seal is e ected, and none of t e melted wax can escape. Owing to the peculiar shape of the cavity 10-12 and the position of the wick 11, ractically all of the wax-oil m, which is retamed in the support 9, is capillarily attracted and consumed simultaneously with the final destruction of the wick.
The usual ornamental wire-cage screen 26 is disposed in the slightly flaring top-end of the globe 19, for excluding insects and for otherwise protecting the top of'the lamp.
The candles 11 are made of slow burning wax and are usually rovided in sizes whic will burn continuous y for eight to ten days without renewal.
Having thus described my invention, what I c aim as new and desire to secure by Letters Patent, is-
1. In a sanctuary lamp, the combination 1,255,614 tell.
with the candle and the base, of a sup ort for the candle located in the base, a ru ber packing ring surrounding the support, a transparent cap mounted on the candle adapted when the candle melts away to .telescope said packing ring for preventing es-,
