SELF-CARBURETING LAMP.

SPECIFICATION forming part of Letters Patent N 0. 788,427, dated April 25, 1905. Application filed April 30, 1904. Serial No. 205,788.

To all whomit may concern.-

Be it known that I, HENRY M. REIGHEN- BACH, a citizen of the United States, residing at Riverdale, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Self-Oarbureting Lamps; and I do hereby declare the following to 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.

My invention relates to improvements in self-carbureting lamps; and the object of my invention is to produce a simple and easilyoperated lamp of this description and one primarily intended for purposes of illumination in connection with an incandescent mantle, although the lamp may also be used for heating purposes.

\Vith these objects in view my invention consists in the construction and combinations of parts, as hereinafter described and claimed' in the accompanying drawings, Figure 1 represents a vertical section of my improved lamp, and Figs. 2, 3, 4, and 5 represent details thereof.

(0 represents the body of the lamp, which is preferably round and made of any desired material, such as metal or porcelain. The body a of the lamp rests within a support 6, which in turn rests upon a support 0, preferably of metal and provided with an open bottom. Through the supports 6 and c, at the pointwhere they meet, extends a tube (Z, the upper part of which is closed by a gauze partition e and which is provided at about its middle portion with a perforated disk f, the perforations in which are adapted to be opened and closed by the rotatable valve g, which is provided with perforations adapted to register with the perforations in the disk f.

it represents a cap adapted to fit over the lower end of the tube (Z, the parts alto it forming a drainage apparatus, asin my invention no oil or burning fluid is contained in the lamp except that held by the absorbent disks hereinafter referred to. Any ordinary lampsupport, however, may be used, and my lamp may be fitted into the kerosene-lamp bases now in use.

Within the body a of the lamp is a series of annular absorbent disks i, made of felt or other suitable absorbent material. Each of these disks 2' is provided with a central opening for the reception of the tube 7' and with a series of openings in preferably arranged concentrically around the central opening for the downward passage of air. The openings in the various disks are of course located above each other. I find it desirable in most 6 cases to separate the absorbent disks Z? by disks of metal or pasteboard Z, perforated like the absorbent disks 4,. These disks pre vent the fluid from settling in the bottom of thelam p. Iprefer to useinthislamp gasolene 5 of about 76 but I do not confine myself to the use of such a burning fluid. Furthermore, it is necessary or desirable in all carbureting devices to supply external heat thereto to prevent the refrigeration of the fluid caused by evaporation held by the absorbent. WVhen fluids of higher boiling-points than gasolene are used, the metal disks conduct the heat from the tube j into the absorbent material, which tube is heated by convection from the tube 8 and also by conduction from the disk 11.

The body of the lamp is closed, except, as hereinafter described, by the plate m,- but the top is open, and this top is closed by a curved cover oa preferably made of metal and pro- 0 vided with a flanged ring which fits down over the top of the body a of the lamp. Through one side of the cover a projects a tube 0, provided With a series of perforations p, the inner part of this tube being closed by a gauze partition (1. Within the tube 0 is a valve 9, provided with perforations s and a milled head t, by turning which the perforations 8 may be caused to register with the perforations 9, thus permitting airto pass inside of 9 the cover a.

Resting on top of the cover it is a ring 2, provided with perforations a, and on this ring rests another ring 8, provided with perforations 2;, one of which is much larger than the others, as shown in dotted lines in Fig. 2.

Located centrally of the lamp-body ais the tube j, open at the bottom and top and .provided with rows of perforations w and o,adapt ed to register with the perforations in the 5 rings 2 and 3. This tube supports the gallery .2, which is of the usual construction and which in turn supports the chimney 1. This chimney is of glass when the lamp is used for illuminating purposes; but it may be replaced by a metal chimney about eight inches long when the lamp is to be used for heating purposes.

The gallery 2 is provided with abead 4and a reduced portion 5, fitting within the tube j. This tube has a slot 6, shaped as shown in Fig. 2, in which a pin 7, which isattached to the gallery, is adapted to engage, this being for the purpose of preventing the gallery from being disengaged from the tube j. Opposite the slot 6 is a similar slot 45, in which the bracket 18 works. Within the tube] and separated from it by an annular space is the tube 8. The lower end of this tube 8 is movably mounted on a stepped base 9. Pins 10, attached to this base, work in slots in the lower part of the tube 8, similar to the slot 6, (shown in Fig. 2,) and permit the tube 8 to be partially rotated on the base 9, the tube 1', soldered to the base 9, surrounding the lowest step thereof. The stepped base 9 is soldered to the plate m. A partition 11 practically closes the annular space between the two tubes and. 8, this partition being located opposite the junction of the rings 2 and 3. This is to cause the air which enters through the perforations u and w to pass downwardly, as will be hereinafter more fully described.

Attached to the gallery 2 is the cap 12, pro vided with perforations w, through one of which the supporting-wire 16 of the mantle passes. Within the cap 12 is a ring 13, having a large central perforation, and the ring and cap together support a dome-shaped screen 14. which is preferably fastened to the cap 12 by screws. The upper end of the mantle 15 is supported by meansof a loop on a hook formed on the horizontal portion of the bent wire 16, which wire is movably secured by a set-screw 17 in a bracket 18, (see Fig. 3,) which is attached to the gallery .2. One end of the bracket 18 works in the slot 45, and the other end engages a slot in the ring 19, which is secured by screws to the tube 8. (See Fig. 3.) The set-screw 17 clamps the mantle-hold ing wire 16 in the bracket 18, which is fastened to the ring 19 and also to the gallery 2. It follows that a partial rotation of the gallery in a horizontal plane will move the tube 8. This is for the purpose of opening the gas-valve in the lower part of the lamp, which is effected as follows:

20 represents an arm passing through slots in the tube 8. central portion 21, provided with a square 65 opening 22, (see Fig. 4,) in which opening is This arm 20 has an enlarged mounted the squared top 25 of the gas-valve 26. The upper part of the gas-valve 26 is solid and the lower part is tubular, as shown at 27, passing over the top of a tube 28. The top 28 is provided with perforations 29, which are adapted to register or not, according as the valve 26 is opened or closed, with perforations 30 in the valve 26; Surrounding the perforations '30 are the troughs 31, (see Fig. 5,) which are inclined downwardly, as shown in Fig. 1, and slotted, as shown at 32, so that the ascending air breaks up the supply of gas and becomes thoroughly mingled with it. Below the lower edges of the troughs 31 the tube 8 is provided with a series of perforations 32 to admit'air beneath the supply of gas. The tube 28 passes downwardly through the stepped base 9 and is provided with openings 33 to admit the gas or vapor from the body of the lamp. The gas passes upward through holes 34 in the plate on, which holes are covered by wire-gauze 35, then passes through the holes 33 into the tube 28, and out through the perforations 29 and 30, where it is mixed with the air, and the mixed air and gas pass up to the mantle, where they are burned. If the perforations 29 and 30 do not register, this of course cuts off the supply of gas or vapor to the lamp, putting it out. Through the tube 28 passes a shaft 36. provided with a small fan 37 on its top. Aplate 46, mounted on the top of the tube 28, furnishes a bearing for the shaft 36, which also passes through the plate on, which furnishes a second bearing therefor and is revolved by means of a gear-wheel 38, which meshes with a gear-wheel 39, which is mounted on a stubshaft 40, which stub-shaft carries a gearwheel 41, meshing with a gear-wheel 42, carried on the lower end of a shaft 43. The upper part of the shaft 43 is squared and inserted into a squared opening in the bottom of the shaft 47, which is provided with a milled head 44. The shaft 47 is supported in a sleeve 48 in the cover a.

When it is desired to start the lamp, the valve 26 is opened and the milled head 44 turned by hand, thus turning the fan 37 and forcing a current of mixed air and gas upwardly, the air entering through the apertures p and s and u and The gas mixed with air rises through the tube 8, being driven by the fan 37, and passes out through the apertures o in the ring 3, and the mixture is ignited by means of the large apertures shown in the ring 3 in Fig. 2. After the gas has been ignited, the ring 3 is turned so that the small apertures o register with the apertures y. Air will then flow in through the apertures o and g outside of the mantle and will flow in through, the apertures an and u down around the tube 8 through the apertures 32, where it will mix with the gas coming out of the tube 28, although this gas has already been partially mixed with air which comes in IIO through the apertures 19 and s, and passes downward through the openings it and upward through the openings 34 and 33. By means of the rings 2 and 3 the supply of air may be accurately regulated, and by means of the gas-valve the supply of gas or vapor may also be exactly regulated. The gallery, mantlesupport, mantle-cap 12, and tube 8 all move together, the extent of movement being determined by the length of the slot 45. The valve 26 can thus be opened or closed to start or stop the flow of gas and air by simply turning the gallery. The higher the boilingpoint of the fluid the more air must be admitted through the apertures g0 and s, and by means of the various apertures the supply of air and gas or vapor to every part of the lamp may be regulated to a nicety, so that the gas when ignited at the mantle 15 will burn with a non-luminous flame.

A very important feature of my invention is that the current of air which passes downward between the tubes jand 8 is warmed by contact with the tube 8, supplying heat to prevent refrigeration of the absorbent material containing the liquid fuel and the consequent reduction of the rate of volatilization thereof. It should be noted particularly that if for any reason the fuel becomes less volatile a comparatively larger portion of air travels through the absorbent material and a smaller portion between the tubes 8 and but in this case the air between the tubes 8 and j becomes more highly heated. Consequently the fuel is more readily volatiliZed than before,as already explained. Thus within certain limits the lamp automatically regulates itself.

. In assembling the lamp the parts are first placed on the plate m, which is then'placed on the support and the circular casing slipped in place. Then the cover it is put on and the various upper portions of the lamp placed in position.

, To till the lamp, the gallery, chimney, &c., are removed. The tube a and the cap 7b are also removed, and fluid is poured through the lamp-soaking into the aborbent packings z', the excess flowing ofl'.

While I have thus described my invention, I wish it to be understood that I do not limit myself to .the exact details shown and described, as these might be varied greatly without departing from the spirit of my invention.
