SANCTUARY-LAMP.

Application filed September 23, 1918.

ro all whom it may concern:

Be it known that I, BERNARD l\'lULLnu llli-iYM, a citizen of the United States, residing at Kansas City, in the county of Jack 5 son and State of lhlissouri, have invented certain new and useful Improvements in ("i J: imnctuary-Lamps, t whlch the iollowlng 1s a speclfication.

This invention relates to sanctuary lamps,

l0 and my object is to produce an oil lamp hav- 15 this clmracter wherein provision is made tor feeding the wick upward autouuitically at a rate which will compensate for the relatively rapid consumption of the wick and slow consumption of the oil. More specili cally my object is to produce a lamp of the class mentioned. in which a consumable wick as distinguished from a non-consumable one,

moved uninterruptedly upward at a rate sul'licient to insure the presence of a fresh part of the wick in condition for instant ignition, just above the level o'l. the oil. and thereby compensate with the gradual lo wering of the level of the oil. for tl" s shortening of the wick by the combustion maintained at its upper extremity.

With these objects in view the invention consists in certain novel and useful features Off construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing in which:

Figure 1, is a central vertical section of a sanctuary lamp embodying the invention.

Fig. 2, is a horizontal section on the line lI1I of Fig. 1.

lln carrying out the invention an ordinary oil containing vessel 1 is supported as shown or in any other suitable manner in a hollow metal base 2, said vessel. (littering from the usual type in that it is provided with an opening in its bottom as at 3. A vertical tube 4- detachably engages the lower end of the vessel and communicates therewith to through the opening thereof, a gasket 5 be- Specification of Letters Patent.

Serial No. 255,358.

supportwhioh is hollow and open at the bottom, is provided with a central opening 9 receiving the lower end of tube i, and a set screw 10 is employed to secure the tube against downward movement. The support (5 is provided with a bracket or shell? 11 for the support of a motor or clockwork 12 con ventionally illustrated, and a shaft '18 of said clock work is provided with a flanged pinion 14: to project into tube 4: through an opening 15 therein and engage a rack bar 16 within said tube, the flanges ot the pinion serving to prevent lateral movement of the rack bar. The rack bar is equipped at its upper end with a piston 17 for movement up and down within the tube and for prevent ing leakage of: the oil below the piston one or more packing rings 1'7 are provided.

The piston is provided in its upper end with a socket 18 for receiving the lower end of a still consumable wick 19, which extends up through the opening in the bottom of the vessel 1 to a point slightly above the level of the oil therein. To prevent disengagement of the rack bar from the pinion, the former is provided with an antitt'riction roller engaging the wall of tube 4 at the opposite side thereof from said pinion.

With the parts in the positions shown in Fig. 1, that is with the vessel containing a full charge of oil as indicated by the dotted line near the top of the vessel and the wick protruding slightly upward from the oil, the lamp is ready for operation by applying a match or taper to the upper end of the wick and starting the motor or clock work in operation. As the consumption oi the wick will be rapid as compared to the consumption of the oil, the former will be fed upward by the clock work at an im perceptible speed, in fact the speed will be so slow that the piston may not complete its upward movement to a point adj aeent the bottom oi the vessel for a period of several d ays, the clock work being so geared that the piston shall complete its upward movement about the time the consumption of the oil in the vessel is effected, and in this connection it may be stated that experience has shown that the conventional type oi vessel will hold sufficient vegetable oil to support combustion of: a wick for a period of about eight days. Of course, by changing the pro portion of the parts and the quantity oi? oil and th ength of the wick, the lamp may be adapted for continuous operation for a longer or a shorter period as desired. By the arrangement describedit will be obvious that a fresh portion of the wick may be maintained above but in close proximity to the surface of the oil and hence insure continuous combustion in'the shape of a small fiame as'indieated at the top of the wick in the drawing, a very small flame bein desirablefor economic reasons. it will, of course, be apparent that the invention is susceptible of modification in various particulars without departing from the principle of construction and mode of operation described, and that I reserve the right to make all changes falling within the spirit .and scope of the appended claims.

I claim:

1. An oil holding vessel having an opening in the bottom, a vertical tube below the vessel and communicating with the said openlng thereof, a stlff wick extending ver- 1 tically in said tube and vessel and protruding above the level of the oil, and means within said tube for imparting upward movement to and sealing the tube at the lower end of the wick.

2. A sanctuary lamp comprising a vessel containing oil and an opening at the bottom, a tube depending from and communicating at its upper end with the opening in the vessel, a piston within said tube, means for imparting slow upward movement to the above the level of the oil in the vessel, driving means, and means for transmitting power from the driving means to the piston to impart slow upward movement to the wick.

4. A sanctuary lamp comprising a vessel containing oil and provided with an opening at the bottom, a guide tube depending from the vessel and communicating with the same through the said opening thereof,

a piston within said tube, a wick resting on said piston and extending up through the opening of the vessel to a point above the level of the oil therein, a rack bar depending from the piston within the tube, a pinion engaging the rack bar, and automatic means for operating the pinion to effect slow upward movement of said wick.

5. A santuary lamp comprising an' oilcontaining vessel having a bottom opening, a tube depending from the vessel and communicating with said opening, means slidable in said tube and forming a liquidtight partition therefor, and a stiff combustible wick extending within said vessel. and'down through the opening in the bottom thereof and resting on said partition within said tube.

6. A sanctuary lamp comprising an oilcontaining vessel having a bottom opening, a tube depending from the vessel and communicating with said opening, a piston in said tube provided with a socket in its upper end and forming a liquid-tight partition for the tube, a stiff consumable wick extending within said vessel and through the opening thereof and fitting at its lower end in the socket of said piston, and automatic means for imparting slow upward movement to the piston to raise said wick at a speed to insure maintenance of a fresh portion of the wick above the level of the oil in the vessel regardless of the quantity of such oil.

In testimony whereof I affix my si nature.
