CASS'IUS MONTEZUMA RIOHMONEOF EV YORK, N. Y.

OIL LAMP AND BURNER.

SPECIFICATION forming part of Letters Patent No. 454,686, dated dune 23,1891. Application filed October 9,1890. Serial No. 367,593. (No m n T0 aZZ whom it may concern:

Be it known that I, CAssIUs MONTEZUMA RICHMOND, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Oil Lamps and Burners, of which the following is a specification.

My invention relates to certain new and useful improvements in oil-lamps.

It has for its object to so construct and ar range the several parts that it may be easily rewicked and the internal parts so simple in their mechanical construction that any one can at once understand and manage the same.

In order that those skilled in the art may know howto construct and use my improved lamp, I will proceed to describe its construction and operation, referring by letters to the accompanying drawings, Wherein Figure 1 represents a central vertical section of a lamp embodying my improvements; Fig. 2, a section of the air-tube on the line 2 2, and Fig. 3 a detail of the wick-raiser.

A represents the oil-reservoir, B the cen tral air-tube, and O the Wick surrounding the air-tube B. The wick C may for a part of its extent be surrounded with a perforated covering D.

Within the reservoir A, and on one side of the space occupied by the wick C, I form a vertical channel E, open at the side next to the wick. F is a short block of metal or other suitable material so proportioned that it will exactly fit within the channel E and be capable of vertical movement therein. This block E is provided on its exposed side with one or more short teeth or spursF, adapted to penetrate the wick or the perforations in the wickcover D. The blockF is connected bya screwthread or otherwise to a flexible opera-tingrod G, composed of coiled wire or fiat spring metal provided with an operating knob 01' handle at its upper or free end. From the construction described. it will be seen that when the teeth F of the block F are located in the perforations of the wick-cover D or caused to penetrate the wick fabric, and the block is then caused to enter the channel E from the top, that owing to the proportions and relations of the block and channel it is impossible to disconnect the teeth or spurs F from the wick or its perforate covering without raising the wick sufficiently to permit the block to entirely leave the channel, and consequently any movement of the block through the medium of the rod G necessarily produces a corresponding adjustment of the wick. The operating-rod G, whether made of coiled wire or of flat spring metal, is made with a slight curve, as shown, so that it is always in frictional contact with one side of the channel E, and any accidental falling or lowering of the Wick is avoided.

W ithinthe central air-tube B and centrally 6 5 therein is constructed a small tube L, terminat-ing at its upper end a short distance below thetop of the air-tube B and extending downward to the base of the reservoir and curved outwardly and through the side of the lamp to a point near the base of the bowl. Within this tube L is arranged a coiled wire or other flexible operating-rod K, provided at its outer end with an operating-knob K, and the opposite end of the rod extends upwardly to a sufficient height to form a proper contact or connection with a central leg or pedestal secured to the air-distributer H, and from the construction and arrangement shown it will be seen that the air-distributer H may be readily and expeditiously raised or lowered to control the proper distribution of air to the flame by simply raising or lowering the rod K, and the frictional contact between the spring-rod and the curved bottom portion of the tube L prevents any accidental movement of the rod after the proper adjustment has been made. The air-distributer H, which forms one part of my invention, consists of a double-walled tube made of gauze or properly-perforated o sheet metal, and these walls are parallel or concentric except at the immediate top portion, where the exterior wall is turned inward at an angle of about forty-five degrees, as clearly illustrated at H in the drawings, and 5 connected with the closing non-perforate cap H which is made in the form of an inverted cone. The upper or exposed surface of this cone is nickel-plated or otherwise highly polished to form a reflect-or, and the under side of said cone acts as a deflector to control and direct the air toward the perforations in the oblique (or mansard) portion of the air-distributor in such manner that it will be delivered to the, top otthe flame at an angle of about forty-five degrees.

M is a cap adj ustably connected to the lower end of the tube B, and said tube and cap are provided with openings through the sides thereof in order that a greater or less supply of air may be admitted to the tube B accordingly as the openings referred to register to a greater or less degree, and the cap M 1. The wick-raising device consisting of the open-sided channel E, the block F, having spurs F, and the bent flexible operating-rod G, in combination with the wick-supporting tube 13 and the interposed wick C, substan tially as hereinbefore set forth.

2. The air-distributer I-I, composed of double perforated walls, the outer wall obliqued or inclined inwardly and closed at the top by an inverted-cone-shaped cap polished on its exposed surface and arranged to act asa deflector of the air and a reflector of light, substantially as hereinbefore set forth.

3. As a means for adjusting the air-distribbase of the bowl in a curve, in combination with an interiorly-arranged flexible rod K, substantially as shown and described.

Signed at New York, in the county of New York and State of New York, this 23d day of September, A. D. 1890.
