IMPROVEMENT IN LOC'OMOTIVE HEAD-LIGHTS.

Speciiication forming part of Letters Patent No. 46.380. dated February 14, 1865.

To all whom it may concern:

Be it known that I, THOMAS J. NEWLAND, of Utica, Oneida county, New York,have invented a new and usetul Improvement in Locomotive Head-Lights or RailroadLamps; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, which drawing represents a sectional view of the burner containing said improvement.

The nature of my invention consists, first, in the use and arrangement of four tubes in the construction of the burner, by means of which the lamp is prevented from leaking and the wick is readily raised and lowered Without its being caused to rotate, as in other cases where a screw is used and, second, in making the inner tube bell shape at the top and bottom for the regulation ot' the air to the ilame.

A A is the outer barrel of the wick-tube; B B, the inner one. G C is the screw, and D D the inner tube with the bell-shaped ends E E and F F. G G is the wick-thimble, and I a pin therein playing in the screw C U, and N is a notch in the flange of G, which plays on the way H, attached to the inner side of A.

O O is a milled ring attached to D for turning the screw C G. K is the feedtube; I I, a circle of Ventilating perforations. M is the button, and L a perforated cup to regulate the ingress of air to the center of the wick. The outer and inner barrels of the wick-tube, A A and B B, are of the ordinary form and are united together near the bottom by soldering them to an interposed ring, as seen at B B. Below this is the circle of holes J J, through A A, to keep cool the bottom ot the burner. The inside cylinder or barrel, D D, is

beveled outward at both ends,as seen at E E and FF, and just at the bottom ofA A is attached O 0. C C is tted close to B B, and has a screw on its outer surface, and is rivet( d firmly to D D at the top, as seen atE E. The wick-thimble G is of the usual form, and has a pin, I, on its inner side, which plays into the screw G, while the flange on G hasa notch, N, which slides over the way H, attached longitudinally to the inside ot' A.

To raise or lower the wick, O 0 is turned, which causes G C to turn in the same direction, and as G cannot turn, by reason ofthe notch A and way H, it is forced to move up or down as O O may be turned by the screw C acting on the pin l.

The ben-shaped @Das 0f D D permit the air A to ascend more freely and to strike the iiame `nearer to the point of combustion than if the upper end was straight.

The advantages of this form of construction, in addition to that just stated, are, its simplicity and economy; the impossibility of oil escaping, except that which drips over the top of the burner, and the doing away with the necessity of rotating the wick, as is usual in other cases where the screw is used.

I claim- 1. The combination and arrangement ot' the barrels or cylinders A, B, C, and D, used and operating substantially in the manner and for the purpose mentioned.

2. The beveled ends of the inner cylinder, D, separately and in combination, used and operating substantially :in the manner and for the purposes mentioned.

THOS. J. NEWLAND.
