UNITED STATES PATENT OFFICE.
I WILLIAM T. WOOD, OF MOUNT JULIET, TENNESSEE.
IMPROVEMENT IN AUTOMATIC LAMP-EXTINGUISHERS.
Specification forming part of Letters Patent No. 189,826, dated April 17, 1877 application filed December 16, 1876.
To all whom it may concern:
Be it known that I, WILLIAM T. WOOD, of Mount Juliet, in thecounty of Wilson and State of Tennessee, have invented a new and valuable Improvement in Automatic Lamp- Extinguishers; and I dohereby declare that the following; is a full, clear and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked.
Figure l of the drawings is a representation of a vertical central section of this invention. Fig. 2 is a top view. Fig. 3 is a side View, and Fig. 4 is a detail.
This invention has relation to lamp-extinguishers;'and it consists in the construction and novel arrangement of the pivoted caps, having their lower ends extended nearthe floor ot' the burner, and spread to keep, between said lower ends or guards and the wick-tuhe, loose balls, by the action of which, when the lamp is tipped in any direction, the caps are operated to extinguish the flame, as hereinafter shown and described.
In the accompanying drawings, the letter A designates the body of the burner, having a perforated or ventilated floor, B, and wicktube 0, constructed in any ordinary-manner, and provided with the usual flame cap or cone D. E E represent the extinguishingcaps, which may be formed from sheet-metal blanks, of the shape indicated in Fig. 4 of the drawings, or otherwise made to provide lateral pivot-arms a. and extensions I) near the burner-floor. These extensions are spread latorally, and curved around toward the wicktube, to form, in connection therewith, in closures for the reception of the actuatingballs F, which rest upon the burner-floor, and, when the lamp is in the upright position, are steadied against the wick-tube, or otherwise, by means of depressions c in the burner-floor, which is made concave orshelving toward the same.
The pivot-arms a are advanced in position, so that the weight of the caps is in rear, and they will fall open, consequently, when the lamp is upright, sufficiently far to be entirely out of the way of the flame. At the same time the balls will rest in their seats near the wick-tube, the guards in the construction illustrated resting against them in a somewhat closer manner, the movable caps thus forming a draft-chamber near the wick-tube, which serves to keep up a central current, and prevent undue heating of the chamber within theflame-cone.
Draft-openings may be made in the extensions or guards b, to facilitate the admission of air to the wick.
G indicates a double-branched lever, which is inserted through perforations rain the flange of the burner, and is designed to engage, by its branches, with the under edges of the lateral arms a of the caps, said branches passing on each side of the wick-tube.
By pressing upon the projectingloop or extension of this lever outside of the burner flange, the caps will be brought together, and the flame instantly extinguished.
The same result will follow if the lamp be overset or tipped in any direction. In this case the balls, bein g displaced from their seats in the burner-floor, will pusli the guards I) outward, and thereby bring the caps over the burning wick.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, ls-
I. In a lamp-burner, the extinguishing-caps E, having the extension-guards 1) near the burner-floor, curved or bent laterally, to form,
WILLIAM THOMAS WOOD.
