LAMP.

SPECIFICATION forming part of Letters Patent N0. 781,036, dated January 31, 1905. Application filed February 2 7, 1903. Serial No. 145,419.

To all whom, it may concern: Be it known that I, CLAYTON VoN CULIN, a

citizen of the United States of America, and a resident of the town of Wayland, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Lamps, of which the following is a specifi- ;stant height and uniform temperature and for safety against explosion or fire or injury to the glass chimney from internal or external causes. A

Heretofore it has been diflicult and in most cases impossible with-any lamp or burner now in use to keep the flame at'a uniform height and temperature .without occasional ad justment of the height of the wick, for the reason that when the lamp is first lighted all its parts and the oil or other fuel it contains are cold. If the wick is then adjusted so that the flame will be at the height required to give off the light and temperature desired, in a short time as the chimney, burner, andparts of the lamp and the oil become heated the draft up the chimney will increase, producing more rapid combustion of the oil or other. fuel used, thereby increasing the height of the flame and heat units or temperature given off in a given period of time, as well as causing the flame to smoke from defective combustion of the fuel. This excessive height of wick, high flame, and excessive temperature are also dangerous conditions, causing liabihty of breaking the glass chimney, of overheating the Oil, causing it to expand and overflow, or to give off explosive vapors, which may ignite, explode, and scatter the burning oil and set fire to surrounding objects. On the other hand, the usual lamp without my improvement, if the wick is turned low when first lighted to avoid the danger of the flame being too high when the parts of the lamp and the oil have been warmed up will give off disagreeable and offensive or objectionable odors from imperfect combustion of the fuel, be-

Fig. 4 shows a reducing-collar'to be used if theburner and fireproof hollow tubular collar are of different sizes for the purpose of connecting themproperly. Fig. 5 shows a lamp fitted with fireproof and safety improvements. Fig. 6 shows a transverse vertical sectional view M N of fireproof hollow tubular collar G, connecting-tubes D E, and water-tank F on M N The arrows show tr lirections in which the currents of cold flow into and warm water flow out of the low tubularcollar G. The dotted lines, wh shown, indicate the interior outline of a parts.

. Similar letters refer to similar parts in a the views.

Many of the oil-lamps in use are made with interchangeable burners of various standard sizes, deslgnated as No. 1, No. 2, &c.,

to which I refer in the following specification.

The glass or metal lamp oil-reservoir O (shown in Fig. 1) has an opening and cap R where the lamp is filled, a handle S, the collar H, to which the hollow tubular collar Cr (shown in Fig. 2) is screwed or otherwise connected, and a reducing-collar Q, (shown in Fig. 3,) which supports the burner I and hood K.

My fireproof improvement (shown in Fig. 2) comprises a hollow tubular collar G, with one or more tubes D and E connecting the hollow tubular collar G with the water tank or reservoir F, forming an attachment capable of being placed on any lamp between the collar H of the lamp and its burner I, the tank or reservoir F, connecting-tubes D E, and hollow tubular collar G being capable of containing water.

K is a safety-hood, (shown in Fig. 3,) partially or entirely open at top and bottom and having one or more apertures L, covered with mica or other non inflammable material, through which to view the flame, P P being the arms connected to the burner to support a safety-hood K. The openings at top and bottom may be partially closed by wire-gauze or perforated metal, as desired.

In Fig. 4, Q, is ared ucing-collar fitted to be placed on my fireproof improvement if a No. 1 burner is used to fit the burner and fireproof improvement properly together. My fireproof improvement may be put on a lamp with a No. 2 collar, and a No. 2 burner will fill my fireproof improvement. A No. 1

burner may be used with my fireproof improvement by using a reducer Q to connect them.

To use my improvements, my hollow tubular collar Gris screwed on the collar of the lamp at H. The burner I is placed on or in a hollow tubular collarG, a safety-hood K being placed on the supports P P, as shown. The wick W passes through the burner I, wick-tube B, hollow tubular'collar G, and collar H into the lamp oil-reservoir O. The hollow tubular collar G (shown in Figs. 2, 5, and 6) may-have a tubular projection onits lower edge,'as shown in Fig. 6. between the letters G and N. This tubular projection may have a smooth surface. and fit into the cavity of the collar H, or it may have a screw-thread on its exterior surface which may be screwed into a corresponding screw-thread on the inner surface of the collar H. In a similar manner if a No. 2 burner I is used its lower portion may be, placed, screwed, or secured on or into the top of my hollow tubular collar G; but if a No. 1 burner is used, as it is too small to. fit properly into the upper portion of the hollow tubular collar G, a reducing-collar Q must be placed between the top of the hollow tubular collar G and the burner I. This reducing-collar Q, as shown in Fig. 4:, has a tubular projection on its lower portion adapted to be placed or screwed into the upper part of the hollow tubular collar G, the lower part of the No. 1 burner being fitted or screwed into the upper portion of the reducing-collar Q.

The operation of my automatic fireproof and safety improvements after connecting the parts-as above described is as follows: The lamp-reservoir 0 having been filled with oil or other suitable fuel, the wick is lighted and adjusted to the desired height. The watertank F having previously been filled with cold water, when two tubes D and E are used the cold water passes through the lower tube E into and through the hollow collar G, in which it becomes heated bythe heat from the flame, and thereby becoming lighter ascends and passes out of the collar Gr through the upper tube E, (or if only one connectingtube is used through its upper portion,) back into the tank F, rising to the top of the ,of any special shape or material.

tank F and coming in contact with the air, is cooled, the cooler water at the bottom of the tank F continuing to pass through the lower tube D (or if onlyone connecting-tube is used through its lower portion) into the hollowtubular collar G, keeping the hollow tubular collar G cool and preventing the radiation and transmission of the heat from the flame L through the burner I to the oil in thelamp 0, thus automatically keeping the lamp and oil cool and the flame and temperature at a constant height.

Sometimes from defective manufacture or annealing of the glass lamp-chimneys or from sudden changes in the external air or sudden drafts of air the glass lamp-chimneys may break, allowing the flame of the lamp to smoke or to be blown in contact with some combus- .tible material or allowing combustible material to be blown against it, thereby becoming ignited, causing disastrous conflagrations. The safety-hood K is designed to protect the chimney from liability ofbeing broken by external causes or sudden changes of external temperature or if it should be broken from any cause to shield the flame and prevent any disagreeable or dangerous consequences.

I do not confine myself to the use of lamps of any special form, style, or material. Neither do I confine myself to the use of a lamp-wick The wicks may be flat, single or duplex, round, circular, or hollow, and the burners may be of any kind or shapefiat,single or duplex, round,argand, oval, circular, or hollow.

My fireproof and safety improvements may be of any suitable size and shape required in each case and may be made plain or ornamented, asdesired, as I do not confine myself to the design and shape shown in the drawings, which may be varied as required by circumstances provided the principles of my invention are adhered to.

My water tank or reservoir may be open at the top, preferably with a circular collar or rim inside, as shown, although the rim is not essential and may be dispensed with. I have shown a cylindrical tank in the drawings; but it may be rectangular or of any other suitable shape desired.

Among the advantages of these improvements are that they may be attached to any lamp. They may be attached to any burner. When a burner becomes defective, it can be replaced at small cost. A lamp fitted with these improvements is fireproof, is'absolutely safe, and cannotoverheat, smoke, or raise the flame above its normal height. Even with the chimney broken or removed the lamp or oil cannot overheat. When used as a house-lamp, poultry-house, store, incubator-room, cellar, street lamp, stable, sick-room, or night lamp. with a glass chimney, it is perfectly safe, even if the chimney breaks when no person is present. It is free from all odor common to most IIO BEST AVAlLABLE CO tank F, as shown and for the purposes der0 scribed.
