OIL-LAMP.

Specification of Letters Patent.

Patented Aug. a; rare.

Application filed April 14, 1914. Serial N 0. 831,799.

To all whom it may concern:

Be it known that I, SYDNEY HARRY SHER- wool), subject of the King of Great Britain, residing at :H to 50 Granville street, in the cityof Birmingham, England, have invented certain new and useful Improvements in Oil-Lamps, of which the following is a specification.

The invention relates to an oil lamp internally fed by ascending gentle air currents induced by a small fan applied internally to the base of the lamp, and driven by a wound-up spring. In such a lamp the Oll container is surrounded by an outer shell between which and said container a free annular space is left for the flow of air from the inclosed base of the shell to within the burner cone. The burner of such a lamp is built up of three principle parts, burner body, burner cone, and globe or shade holder.

To this kind of oil lamp the invention solely relates, and provides the hereinafter built up of three principal parts, burner parts formed, and fitting each other, and the oil container, and inclosing shell, in a special manner, with the primary object of efliciently supporting the globe or shade holder, and at the same time enabling the trimming of the wick to be easily performed.

The invention comprising said combination of parts is represented by the accompanying drawings.

Figure l is a vertical section of the complete lamp. Fig. 2 is a horizontal section of Fig. 1 .on the dotted lines A B. Fig. 3 is a similar section as Fig. 1, butwith the burner parts of the lamp separated from the oil container and shell body. Fig. 4 is a plan of the lower burner piece Fig. 3.

The shell of the lamp, comprising base a, waist c, and body d, incloses and supports a fan mechanism, 6, and the oil container, f, in the ordinary way, so that gentle air currents, induced by the fan 6, flow upwardly and around the annular space 9, between the body and oil container, in the manner indi-' cated by the arrows, to feed the burner. The mouth of the oil container is internally screw-threaded as at F, and between this month and the body of the shell is the annular outlet 9 from thespace g.

The foregoing construction of parts is well known in a lamp of the kind to which the invention refers The invention combines with the screwthreaded mouth 7' and the annular outlet 9 aforesaid, and with a boundary rim 9 of sald outlet, a burner h, a globe or shade holder i made integral with said burner, and a burner cone a made detachable in respect of said burner and globe or shade holder.

The burner it carries the wick tube 7L and the wick winder if, and is formed at it with an externally screw-threaded shank to engage the screw-threaded mouth f of the oil container The globe or shade holder 2', within which the globe or shade may seat itself at 3 or upon which said globe or shade may be otherwise supported, is formed at 2' with a depending annular skirting, and

tually attached to the oil container f, forms a most QIIlClGIlt support for the globe or shade no matter what its size or weight may be; the cont nuity of the air passages to the wick tube being at the same time maintained by the perforated plate 2' and the annular skirting 2' The burner cone a; is formed at m with a depending annular rim and at m with opposite gaps. The latter engage the stem of the wick winder k to aline the slot 00 of the burner cone with the wick tube, while the rim m fits tightly within a shallow socket g of the globe or shade holder 2' in the manner represented by Fig. 1, this tight fitting sufficiently holding the cone a? in position upon the globe or shade holder so as to surround the wick tube 5 By the removal of the cone w from the integral burner h and globe or shade holder i the wick of the lamp can be trimmed: by screwing off the combined burner h and globe holder 2' the oil container 7 can be filled.

As hereinbefore stated the object of the invention is the rigid support of the globe or shade holder 2' by the combination of parts in a lamp of the kind to which the invention 1 solely relates.

Having now described my invention What I claim and desire to secure by Letters Patent is I The combination with an oil lamp having an oil Well and an outer shell surrounding the well and in coaction therewith defining an annular air passage concentric to the Well and having an annular outlet at the adjoining upper ends of the well and the shell, of a burner comprising a burner body having a Wick tube and formed for engagement in the upper end of the Well, an annular globe holding rim concentrically circumscribing the body, a plate integrally connecting the rim and the-body arranged below the plane of the rim to provide in conjunction With the said rim and body a socket concentric to the body, the plate alin- SYDNEY HARRY SHERWOOD.
