OlL-LAMP.

SPECIFICATION forming part of Letters Patent No. 392,418, dated November 6, 1888. Application filed August 11, 1885. SerialNo. 174,151. (No model.)

T0 at whom it may concern:

Be it known that I, THOMAS 'MARA FELL, of Tenafly, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Oil-Lamps, of which the following is a specification.

My invention relates to an improvement in lamps.

The object of my inventionis to provide an improved means for feeding oil to burners by a system of siphon-tubes, and to use in c011- nection therewith an angular or horizontal burner, whereby a better and more effective light is obtained; and a further object is to provide'a globe or chimney of a peculiar form andconstructi'on to be used in connection with my angular or' horizontal burners.

With these ends in view my invention consists in certain novel features of construction and combinations of parts, more fully .described hereinafter, and pointed out in the claims. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical section of a pendent lamp embodying my improvement, and Fig. 2 is a modification of part of my invention. I

A is the fount or oil-reservoir provided with the opening E; B, the supporting rod or tube which slides in an outer tube, Y, which is securely attached to the plate Z, this arrange ment being fitted with the usual suspensionchains, pulleys, and weights. The lower part of the supporting rod or tube B passes through the top plate of the fount, and is brazed or otherwise fastened thereto, and if a tube the inner end is stopped by a plug, as shown.

F is a T, if for two lights, or a cross, if for four lights, but is made with three or more horizontal openings if more than two lights are to be fed. This T is secured to the lower end of the rod or pipe B, and into it are screwed the horizontal feedpipes F, which pass through the vertical sides of the fount and are fastened thereto.

D is a small tube screwed into F on its under side, and extends down into the chamber A which communicates with the fount A.

H is the outer oil-feed tube of the burner, The tube J is turned in at the bottom,s0 as to fit the tube H, but has one or two small holes, J, for the passage of oil into the small chamber 1, which is formed by the lower portion of the tube H. The upper end of this tube J is also flattened out and made tight by brazing to the tube H, as shown.

A is a right-angled goose-neck connection; but such angle may be varied to any degree found desirable. (See Fig. 2.) One end of this goose-neck screws on or is fitted into the upper end of the vertical tube H, the other end carrying the plate 0.

P are air-holes around the circumference of the upper end of the goose-neck.

F is the wick-holder,having' attached thereto the usual ratchet wheel for feeding the wick; and F is an extension of the lower half of the wick-holder F, the said extension being bent to conform to the shape of the gooseneck.

L is the burner-cap, having the opening L G is a glass globe having two openings, one located at the top and the other at the side thereof, the bottom of the globe being closed. The opening in the side is adapted to fit over the burner, the globe being secured to the plate 0 by means of the lip D and screw E in the ordinary manner. The other opening or outlet 1 is vertical to the lamp. On the upper part of the globe and over the opening is a metal chimney, T, which carries a reflector-plate, K.

I do not wish to limit myself to the use of my improved globe or chimney in connection with the peculiar form of lamp herein described, as it is evident that this improved form of globe 0r chimney can be manufactured and sold separately from the lamp and used in connection with any angular or horizontal burner.

The operation of this lamp is as follows: Oil being poured through the opening E into the fount, it enters the chamber A and passes through the pipes D F H to the wick-tube J. The pipe D extends down to or below the bottom of the oil-reservoir, and the opening J being also below said bottom, permits the oil to flow from the reservoir to the wick-tube v and be maintained at the same height in both until the fouut is exhausted. This system of siphon-feed permits the pipes I to be placed centrally in the fouut, thus giving a strong support to the burner and chimney. \Vhen the wick is ignited, a draft will be created by the air entering through the openings in the plate 0, passing through the burner-cap and escaping through the opening I. This draft will have the effect of drawing the flame in a curved form from a horizontal to a vertical plane. The superiority of this curved flame is that it gives most of its strongest rays of light downward from the under side of the flame, and if a reflector be used the corresponding rays of the other side of the llame will be reflected in adownward direction. A further benefit of my said improvements is in obtaining a shadowless light immediately under the burner, which is effected by the removal of the metal burner and fouut from their usual positions.

As a modification of my said invention, the globe G may be extended in the form of a chimney upward, instead of using the metal top T, and the goose-neck A, which secures the angle of the burner, maybe made so as to enter the lower part of the globe or chimney at an angle other than a rightanglc, as shown in Fig. 2.

Having thus fully described my invention, what I claim, and. desire to secure by Letters Patent of the United States, is

1. In a lamp, the combination, with a wicktube, an upwardly and outwardly bent gooseneck, a perforated plate secured to said gooseneck, and a burner, of a globe or chimney having an openingin its side and another opening in its top, substantially as described.

2. In a lamp, a supply-fouut, a wick-tube located outside of the supply-fouut, and a siphonconduit connecting said fouut and wick-tube, combined with a gooseneck in communication with and located above said wick-tube, a perforated plate upon the outer end of said goose-neck, a globe clamped to said perforated plate, and a burner carried by the perforated plate, substantially as de scribed.

3. In a lamp, the combination, with an oil supply fouut and a wick-tube in communication therewith, of a goose-neck, a perforated plat-e attached to said goose-neck, a globe clamped to said perforated plate and closed at its bottom and provided with two openings, one in its side and one in its top, said globe being provided with an upwardly-extending chimney at its top opening, and a burner extending into said side opening of the globe, substantially as described.

1-. In a lamp, a supply-fouut, a wiclvtube located outside of the supply-fouut, and a siphonconduit connecting said wick-tube and supply-fen nt, i n combination with an upwardly and outwardly bent gooseneck secured above the wick-tube, a downwardly-curved wickcarrier in the goose-neck, a perforated plate secured to the outer end of the goose-neck, and a burner extending from the goose-neck through the plate, substantially as described.

5. In combination with a burner, a globe having a closed bottom and an opening at its side to receive the burner, and another opening at its top, whereby a draft is created which draws the flamein a curved form upward from a substantially horizontal plane, for the purpose specified.

6. The combination, with a burner and a perforated plate, of a globe or chimney carried by the plate, having a closed bottom and an opening in its side to receive the burner and another opening in its top, and an upwardlyextending chimney carried by the globe and surrounding the top opening in the same, substantially as described.

7. The herein-described lamp, consisting, essentially, of an oil-supply fouut, an upright tube located therein, a horizontal tube connected with said upright tube and extending to the exterior of the fouut, an oil-feed tube upon the outer end of said horizontal tube, a wick-tube, an upwardly and outwardly bent goose-neck above said wick-tube, a wick-carrier, a perforated plate, a globe clamped to Said plate, and a burner, as specified.
