KEROSENE INCANDESCENT LAMP.

Specification of Letters Patent.

Serial No. 459,599.

To all whom it Imay concern:

Be it known that I, BERNARD F. Roni-nuo,

useful Improvements in Kerosene Incandescent lliamps; and l do hereby declare the following tc be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rIhis invention relates to kerosene incandescent lamps. It is desirable in devices of this character to have the mantle centrally supported. It has been found that where the mantles are supported from the side, the rods or wires supporting them lie so close to the chimney that they tend to crack the chimney when they become highly heated. It .is also desirable to have the chimney and mantle removable together from the burner. These mantles are very fragile, and in the devices of this character where it is necessary to separately remove the mantle, said mantles are frequently broken.

,It is the object of the present invention to provide improved and economical means `for accomplishing the foregoing objects.

It is a further object of the invention to provide means for spacing the outer wick tube hereinafter described fron the interior of the sleeve from which the mantle is supported. The spacing of the wick tube from this sleeve provides a passage through said sleeve for the air which supports combustion .and-'it has been found the if means are not provided for preventing it, the chimney is sometimes placed on the lamp in such manner that the outer wick tube is not exactly concentric with the sleeve that surrounds it. This of course gives an unequal flow of air and produces a ragged flame.

In carrying out my invention I do not wish to be understood'that it should be confined to the details shown by the accompanying drawings. The inventive idea is roader than the particular embodiment herein presented and described, and embraces in construction and mechanism that which comes within the scope of the claims.

With these and other objects in view the invention comprises the novel features of construction and completion of parts hereinafter described. f

D2, holes E and In the accompanying drawings, Figure 1 is a top view of the lamp with the chimney and mantle attached; 1Eig. 2 is* a vertical section of the'lamp cut in two, lon lines l-2 Fig-3 is'a front view ofthe lamp; Fig.` 4 is a perspective of the burner detached and Fig. 5 is a detailed perspective view of the flame spreader and mantle support.

Similar letters refer to similar parts throughout the several views, in which- A is the lamp-bowl; B is the inner wick tube; C is the wick; D is the outer Wicktube, provided with flange D1, carrying lugs late F; on plate F is a detachable sleeve, (l, containing openings, Irl, and the same is operated by band I with knob J; K is the receiver for the chimney, M; L are the pins attached to tube, K; li is the flame-spreader and mantlerod support ear rying rod N1, said flame-spreader and man tle-rod support carrying arms O, provided rim G1; R is the wick adjustment, which is provided with a collar having a projection I said collar is also provided with set screw A U; V is an angular iron made fast tothe top of` ear frame which acts as a stop for the 'A wie W is thedetachable plug set in bowl A pf the lamp for the purpose oi iilling the Siiid lamp has a bowl of ordinary shape, and is rovided with a central vertical tube which v1s attached. to the bowl at the lower end, the upper end extending above the outer wick-tube and acting as the inner guide for an annular wick which lits around said tube, and is adapted to'fbe raised and lowered thereon. On the outside of wick is a double detachable tube D, and on its upper inward portion is constructed a flange D1, for the purpose of changing the-current of air or oxygen that comes in contact with the iiame, and on said flange are constructed lugs D2, for the purpose of holding the sleeve C that voperates the conical shaped flamespreader and mantle-rod support in a perlect central position, so as to produce a per- E for the purpose of allowing an air passage around its inward portion to keep same cool. At the top is attached 12.` A kerosene incandescent lamp comprising a bowl, an inner wick tube, an outer an annular plate F i wick tube having an out-turned flange at its that acts as a support for a detachable sleeve upper end, a sleeve surrounding said wick Gr, and prevents an unregulated amount of tube, lugs formed at intervals upon the peair from coming up between the outer wicktube and sleeve Gr. In the outward ortion of sleeve G is arow of openings H an inside of said sleeve is a perforated movableband I, made to correspond with said openings. .I is

a knob attached to the perforated movable f band I, for the purpose of adjusting said openings in such a way as to allow t ie required amount of air to pass into the burner.

rl'he upper part of sleeve G extends above the wick-tube and is so constructed as to form an inward projecting flange G2, for the purpose of supporting the conical shaped flames reader and mantle rod support. On' s eeve G, just above the openings in same', is attached a perforated tube K to receive the chimney M; pins L are attached to said tu be K to prevent the chimney from going beyond said pins, and they also form a restfor said chimney. Immediately above the inner wick-tube B is constructed a conical shaped flame-spreader and mantle-rod support N,

and having an opening in its lower and central part, which is intended to receive the mantle rod N1', which supports the mantle in a perfect'centralposition, and which allows the same to hang in a perfect position overA the flame for the purpose of producing a perfectly adjusted flame from all sides; on the upwardedge of said conical shaped flamespreader and mantle-rod 'sup ort is constructed ariiis O, which project tlierefrom and are rovided with notches P, adapted to fit to t ie rim G1, allowing the central mantlesupport and conical shaped flame-spreader, together with the mantle, to be detached from sleeve Cr when lighting said lamp. In the operating appliance of the wick adjustnient, the wick has an adjustable ear R, and

pinion attached, to be operated y a wheelmade fast to said pinion in connection with an angular iron attachment V, vwhich is made fast to the top part of the gear frame, and which is broughtiin contact with a projection 'l on 'collar S, which has a set screw U, and which allows said collarto be 'set at a given point on the vertical shaft, to revent the wick from being turned too hig thus.

LA kerosene incandescent lamp com-k prising abowl, aninner wick tube, an outer wick tube having an out-turned flange at its upper end, a sleeve surrounding said wick tube and lugs formed at intervals upon the periphery of said lflange and adapted to concentrical y' space the sleeve from the outer 6 5 wick tube.

riphery of said Aflange and adapted to concentrically space the sleeve from the outer spreader located poncentrically above the inner wick tube, a centrally disposed mantle support extending upward-ly from said flame spreader, and spaced supporting memu` -i bers extending from the llame spreaderto the upper` edge of said sleeve.
