KEROSENE OiL BURNER FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 726,431, dated April 28, 1903. Application filed June 17,1902. Serial No. 112,078, (No modelJ To all whom it may concern:

Be it known that I, EUGENE HUMPHREY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Kerosene-Oil Burners for Lamps, of which the following is a specification.

My invention relates to kerosene-oil burners for lamps of the common and well-known type which employs flat Wicks, and particularly to an improvement upon the kind described in Letters Patent of the United States numbered 539,813, issued to me May 28, 1895, in which afiame-support and insulator are employed above the wick-tube.

The object of my invention is to gain several advantages which will be derived from a divided cone or cap, as will be explained, and which object is attained by the construction illustrated in the accompanying drawings, in which- Figure 1 is a perspective showing the lower division of the divided cone or cap hinged to the burnerbase in the usual manner and clearly showing its ioraminous top, which supports the flame when in practical use.

above the level of the top of the wick-tube. Fig. 2 is a perspective of the detached dome or deflector which forms the upper division of the cone and is detachable from and the complement of the lower division when in place thereon for prhctical use; and Fig. 3 is a vertical section of the burner complete and embodying'my improvement, with the two divisions of the hinged cone detachably united, as when practically used.

My presentinvention is confined to that part of the burner variously termed the cap or cone or deflector and usually comprised in one piece. In this case it is made in two separable parts, (marked A and B.) Part A is hinged to the base C at D and provided with a lip E, by which it is disengaged from the raised edge formed on the base, into which it is locked by a spring-catch under the lip in the well-known manner. The base C and all its attachments below cap A, including the wick-tube F and Wick-raising device G, are old and well known and in and of themselves form no part of my invention. In my said former patent the flame-platform or insulator, which serves as the seat of the flame above the level of the top of the wick-tube, is inserted in the cone and detachalbly secured therein by a spring, as and for the purposes stated in the patent. In that patent the perforated platform has to be removed fromthe cone in order to clean it and is made detachable for that purpose and is otherwise practically inaccessible for cleaning its upper side, 'and the Wick cannot be trimmed upon the surface of the flame-platform in that construction, which would be desirable and advantageous if it could be.

In my present invention 1 make the hinged cone in two separable parts A and E, each complementary to the other. Part A, with its foraminous top, is formed in one piece and hinged in the usual manner to the base 0 or otherwise suitably attached thereto, and when closed down upon the base, as shown inFig. 1, its perforated top A is elevated, so that its wick-slot A stands above the top of the wick-tube F, as clearly shown in Fig. 3. The flame-supporting top A, being thus constructed as a permanent part of the division A of the cone, is readily accessible for purposes of cleaning on its upper side and fortrimming the wick thereon in the position where it is to burn, while the under side is easily reached for cleaning by turning the lower division of the cone back on its hinge D. The dome Bis suitably formed in one piece with the usual flame-slit through the top and adapted to serve the purpose of a deflector and as the complement of division A. It shuts down upon and around the top of partA, as shown in Fig. 3, and is held thereon by the friction between the two parts arising from the closeness of the fit, or they may be detachably and properly secured together by two slight coincident indentations H and II, which will interlock when the dome is pressed into place on the part A by the spring of the metal, or by any other appropriate fastening, if one should be considered desirable. The parts A and B when thus united serve the same purpose as the usual integral cone, and the more permanent top A, made readily accessible by the removable dome B, more conveniently serves therein as an insulating-platform in place of the former detachable one. In my former patent the detachable insulating-platform is removed from the cone to clean its upper side and to get free access to the interior of the top of the cone to clean that, while in my present invention those purposes are attained more conveniently in a converse manner-that is, by making the insulating-platform a permanent part of the lower section of the cone-while the dome, being removable, may be separated from the platform instead of the platform being detached from the cone as formerly and with asaving in manual laborin construction and adjustment of the burner. The insulating-top A may be perforated, as shown, or be otherwise provided with suitable airspaces around the Wick-slot A to meet the requirements in that respect. When parts A and B are thus constructed and united, two chambers are formed in the cone so constituted, one inclosing the wick-tube under the platform or top A and the other constituting a combustion-chamber beneath the dome and above the flame-platform A, the latter permittingthe passage of the wick and of air through the same around the wick-slot. The flame-platform in my former patent being, as stated, detachable to get at its upper side requires the cone to be turned partly over to accomplish that purpose, and when attached to a lamp in such position the removal of the part is effected with some incon venience both in detaching and in replacing. In my present construction the upper side of the platform is readily accessible without disturbing the position of the cone beyond removing the dome and is then presented in the most advantageous situation for convenient and expeditious cleaning, and the under side is more readily reached by turning simply the hinged section over, which is unobstrucied by any fastenings or attachments for securing the platform. On the platform,

'which' may be flat or slightly crowning, the

wick may be trimmed more advantageously and with better effect on the form of the illuminating-flame. The removal and replacement of the dome, as will be readily understood, is an act of the simplest kind and of much less difficulty than the removal and readjustment of an interior detachable flameplatform held in place by locking attachments, as the dome is wholly external and directly at hand, requiring only to be picked 01f the top of part A and replaced thereon without disturbance of any other part.

I claim 1. In an oil-burner of the character specifled, a sectional cone comprised in two parts, the lower part being attached to the base of the burner, and constructed so as to inclose the wick-tube, with its top forming an insulating-platform above the tube, and having suitable wick. and air passages in the same; and the upper part adapted to be seated on the lower section, and to form a complemental dome over the platform, with a flame-passage in its top; all substantially as specified.

2. In an oil-burner, a sectional cone comprised in two parts, each part beingintegral, and the lower one adapted to be hinged and latched to the base of the burner, and formed to inclose the wick-tube, and to constitute an insulating-platform, with suitable wick and air passages through the same, above the top of the tube; and the upper part adapted to be detachably secured tothe lower part, and to form a complemental deflecting-dome over the platform, with a flame-passage in its top; all substantially as specified.

3. An oil-burner embodying the combination of a suitable base; a wick-tube extending upward from the base; means for raising and lowering the wick in the tube; a sectional cone comprised in two parts, the lower part being detachably secured to the base, and constructed so as to inclose the wicktube, with its top forming an insulating-platform above the tube, and having suitable wick and air passages in the same; and the upper section adapted to be removably attached to the lower part, and to form a complemental dome over the platform, with a flame-passage in its top; all substantially as and for the purposes specified.
