OIL-BURNER FOR LAMPS OR STOVES.

SPECIFICATION forming part of Letters Patent No. 326,706, dated September Application filed September 30, 1884. (No model.)

To all whom it may concern.-

Be it known that I, ELIAS BEACH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improve ments in Oil-Burners for Lamps or Stoves, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to oil burners for lamps or stoves; and it consists in certain details of construction, which will be more fully hereinafter described, and pointed out in the claims.

The object of my invention is to produce a burner in which the amount of air is graduated according to the requirements of the burner, and to separate the different currents supplying the difl'erent parts of the burner, so as to produce the most perfect combustion and to secure the certain and even adjustment of the wick, all of which is accomplished by simple and effective mechanism. These ob jects are attained by the mechanism illustrated in the accompanying drawings, wherein similar letters of reference indicate like parts in the several views, and in which- Figure 1 is an elevation of my improved oil-burner. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a transverse vertical section. Figs. 4, 5, 6, and 7 represent detail views of parts of the burner detached.

B represents a central vertical tube, around which the wick or wicks are placed, and is connected at its lower portion with a horizontal tube, B. Around these tubes a vertical tube, 0, having a removable top portion,C, is mounted, the open sides of which engage with the open ends of the tube B, as shown in Fig. 2, and attached to the bottom plate D, which plate D is arranged to screw into the lamp-collar. This plate D is turned up and is adapted to support an outside tube, E, which is perforated at its top portion, as at e, to admit air to the upper portion of the burner. A partition or rim, F, separates or divides the perforated part of the tube or casing E from its lower portion and causes the air entering the perforated bottom plate D to pass through the horizontal tube B up through the inside of the wick-tube B. Immediately above the tube E a hollow gallery or support, 117, is constructed, which serves as a support for the cone H, which incloscs the upper portion of the burner, this gallery E acting also as a support for the globe or chimney. This cone H is open at the top, as shown, and allows the air entering the perforations e in the top portion of tube or casing E to pass up through the cone and around the flame. The under side of the flange or support E of the gallery has a semicircular extension, G, which forms a chamber around and immediately under said gallery, and is perforated so as to allow the air to pass up through perforations g in said gallery extension and through the perforated flange h of the cone H into the globe and outside of said cone, this column of air being separated from theinternalair-ducts by the cone-body H itself. On the tube 13 is arranged a wick-raising ring or support in the form of a short tube, I, having projections or teeth on the same and surrounding the vertical tube B, which is slotted on two of its sides, as b, to allow a cross-bar, L, connected to the wick-raiser to slide or have free movement therein. This cross-bar L is secured to and operated by a shaft, J, which is situated in the internal part of the tube 13, the lower part of said shaft being screwthreaded, and the cross-bar L being tapped to receive the shaft, as shown in Fig. 2. This shaft J is attached to the bottom of tube B in such a manner as to admit the revolving of the same, and has attached to it a horizontal pinion, M, which meshes with a vertical pinion, M, attached to a horizontal shaft, N, which in turn is operated by a thumb-wheel, S. The upper or smooth portion of shaft J passes through a spider, P, which centers and keeps the shaft in an upright position, and at the same time acts as a support for the button or spreader NV.

The operation of my improved burner is as follows: The wick isinserted through the open flanged portion of the plate D, and passes up around the horizontal tube B and the vertical tube B, and is engaged by the serrated wiek-raising ring I. The revolving of the horizontal shaft N turns the vertical shaft J through the medium of the pinions M and M. The cross-bar L on or attached to the wickraiser I, and traveling in slots Z) in the vertical tube B, and through which the vertical tube passes, causes said crossbar L to move up or down, as desired.

The above operation having been fully carried out, it will be seen that the wick will be fed upward by the serrated ring I, and keep the frame well shaped and in trim; but when the wick-raiser has traveled up as far as possible in the slots b b theremovable portion 0 of tube 0, which presses the wick which it surrounds against the teeth in ring I, is removed, the wick turned back, and the wickraiser lowered, the wicks being again placed in position, and the top 0 replaced to hold the wicks in place, as before.

The air-currents, the direction of which is shown by the arrows, enter and act as follows: The air passing through the perforated bottom plate D enters the open ends of horizontal tube B and ascends through the tube B, strikes the button or spreader NV, and is deflected at right angles. The air coming in through the perforated top of tube E passes up through the inside of the cone H, and is held in contact with the flame. Another current enters through the perforated gallery and flange h of the cone H, and passes up into the chimney or globe between the globe and the flame itself. It will be seen that the current, deflecting at right angles from the button or spreader, deflects the flame in the same manner toward the globe or chimney; but by the counter-currentsentering the cone and gallery the flame is resolved into an oval shape and prevented from coming into direct contact with the globe, and at the same time centering at the most perfect point of combustion, making a flame having an internal and an external current of air, and thus producing a brilliant, clear, and effective light.

In this burner two wicks are used of sufficient size to till the space between the vertical tube B and the'removable tube 0, thus making a continuous wick at and above the wick-raiser, and at the same time allowing the division of the wicks below the wickraiser to pass each side of the horizontal tube B, that admits air to the center of the burner. No part of this burner is below the connection with the lamp-body, the wicks only being brought in contact with the oil in the reservoir, thus, by this construction, preventing the heating of the oil in the said reservoir, which is a serious defect in all burners having a metal tube passing through the oil-reservoirs to admit air from the bottom, or such as have a wick-raiser or a connection to the same that extends down into the oil; and by my construction air is taken into the burner at the bottom through plate D, so that the currents may be less affected by moving the lamp or other causes.

It is obvious that many mechanical changes could be substituted for those shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an oil-burner, the combination, with a vertical slotted'tube having a horizontal tube in connection therewith, of a serrated wick-raising ring encircling said vertical tube and operating by a cross-bar sliding in its slots and a vertical shaft passing through the center of the tubes and wick-raising actuating cross-bar, substantially as described.

2. In an oil-burner, the combination, with the central vertical slotted tube having a horizontal open-ended tube in connection therewith, of a serrated wick-raising ring or tubehaving a cross-bar sliding in slots in said vertical tube, a vertical shaft stepped in the lower or horizontal tube and extending up through the central tube and engaging the cross-bar of the wick-raiser, vertical and horizontal pinions operating said shaft, and the perforated bottom plate holding the inner and outer casing tubes, substantially as described.

3. In an oil-burner, the combination of a vertical and horizontal tube integral with each other, a two-part tube or casing encircling the said vertical and horizontal tubes divided by a partition, the lowermost of said outer casing-tubes being perforated at its bottom portion and the uppermost just above the partition, and a gallery having a perforated semicylindrical extension over which the perforated flange of the cone rests, substantially as described.

4. In an oil-burner, the combination of vertical tube B, horizontal tube B, tube 0, engaging with tube B and having a removable top, 0, perforated bottom plate D, casing E, partition F, gallery and extension G, cone H, with its perforated flange h, all combined and arranged to permit the free flow of air outside and inside of the flame, substantially as described. 1

5. In combination with the slotted tube B, the horizontal tube B, connected thereto, the spider P, the shaft J, mounted in the tube B and said spider and having the reduced portion extending beyond the spider, the spreader W, the shaft N, pinions M M, theserrated wick-raiser, and cross-bar L, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ELIAS BEACH.
