OIL LAMP.

Application filed May 13, 1921.

Serial No. 469,316.

(GRANTED UNDER THE PROVISIONS OF THE ACT MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that I, 'HENRY Counrnnma subject of the King of Great Britain and Ireland, residing at 5 River Terrace, Sun- 5 .bm'y-on-Thames, Middlesex, England, have invented certain new and useful Improvemerits in Oil Lamps (for which I have filed an application in England Feb. 6, 1920, Patent No. 1641,4523), of which the following is a specification.

This invention relates to lamps used in imitation of candles, that is to say of lamps comprising a cylindrical casing of a size corresponding to that of a candle in which a liquid illuminant is burnt.

According -to the invention an oil lamp is provided comprising a casing or reservoir filled with absorbent material which is open at its lower end and is adapted at its lower end to be fitted into a socket in the manner The invention comprises the constructional features hereinafter described.

The socket of the holder may in j the main part be formed as a truncated cone in which the larger-end of the cone is uppermost and the smaller end is secured to, the base of the holder and the upper end of the conical part of the so-cketis flared or extends outwardly for the reception of any being passed into the socket.

The casing or reservoir is advantageously provided of cylindrical form and may at its lower end he formed of a conical shape to engage within the socket at its lower end. The outwardly flaring part of the socket may be formed with an inwardly protruding flange for assistance in the support of the casing or reservoir when introduced into the socket.

It will be understood that the construction immediately before described may be modified in many details without departing from the essential features of the invention which liquid that may rise upwardly on the casing position or otherwise applied and it may be centrally provided with a tube through which a wick may pass, and the tube may be provided with holes or slots by means of which the wick may be adjusted or any other means may be provided upon the cap for adjusting the wick. It will furthermore be understood that the casing of the lamp may be filled with wick alone but it is preferred to provide cotton wool, wadding, asbestos fibre or the like for the absorption of the charge of liquid illuminant, andto avoid the possibility of spilling of the liquid in the case of the holder being upsets The invention is illustrated by way of example in the accompanying drawing in which T Figure 1 represents an Ielevationpartly in section of a candle, lamp providedaccording to the invention. j

Figure 2 is a sectional plan on the line 22 of Figure 1,

Figure 3 is a plan view of the shade-or reflector.

Figure 4: is a detail view of the lower part of the lamp casing orreservoir. M

vits illustrated in the accompanying ing the casing or reservoir a is provided of a tubular form to take the place of a candle, and is open atits lower end and its vantageously provided of such a form as indicated in Figure 2, that is to say by formmg it with alternate projections c and re cesses 0 of similar shape, sothat while the draw-.

plate 0 serves for the support of the casing or reservoir a the dish shaped part c is adapted for pouring the liquid illuminant into the annular space or cavity 6 between the socket Z) and the casing or reservoir a. The socket o is thus open. The plate 0 may be rendered integral with the socket b or example by soldering the edges or surfaces in contact.

As before described the casing or reservoir a serves to contain an absorbent material such as cotton wool and its lower end is advantageously provided of an irregular form topermit of the liquid illuminant passing into the casing or reservoir so as to be absorbed by the absorbent material. This inay be done by torn'iing V-shaped notches a at the edge of the casing a as illustrated in Figures 1 and 4:. At the upper end he casing or reservoir a is provided with a wick tube d, and this wick tube is advantageously provided with a spiral ledge or thread 6 to engage with the spirallower edge f of the centrally disposed boss f which serves to carry the conical reflector g. The boss is integrally provided with diametrically disposed arms 7", whose opposite ends are integrally secured by brazing, soldering or otherwise to the wall oi the shade orreflector g.

The shade or reflectorg is advantageously provided of the form off a hollow truncated cone as illustrated in Figure 1 which may be cut in a plane parallel with the axis of the cone to form a lateral aperture through which the light may be outwardly reflected.

It will be understood that the shade or reflector may be capable of rotation upon the wick tube (Z and in its rotation is raised or lowered so that its upper edge thus serves to reduce or to increase the amount of flame.

An absorbent material such as cotton wool or the like may be inserted in the annular space. Zi in the socket, and in such a case a cylindrical perforated tube may be provi ded to lorm an internal wall 71 (Figure 1) for the annular space 5 through which the casing orre'servoir (it passes. Furthermore a cover plated (Figure 1) may be loosely mounted in position over the dish-shaped plate 0. k I

The shade or reflector may be dispensed with.
