Letters Patent No. 103,048, dated May 17, 1870.

IMPROVEMENT m LAMP-fixTmGUIsHn-Rs.

The Schedule referred to in these. Letters Patent and making part0! the same.

. Be it known that I, J OHN HUGHEs, of New Berne, in the county of Graven and State of North Carolina, have invented a new and valuable Impr0ve-' ment in Lamps; and 'Ido hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making-a part of this specification, and tothe letters and figures of reference marked thereon.

' Figure 1 of the drawings is a representation of a central vertical section of my improved safety-attachment. V

- Figure 2 is an external view thereof.

, My invention relates to safety attachments for bydrocarbon-lamps, and consists, mainly, in the construction of automatic extinguishers, pivoted at the side of the wick-tube, and operated by weights, in such a manner as to cause the flame to be immediately extinguishedwhen the lamp is thrown down or upset.

The letter Act the drawings designates the bowl .13, the wick-tube, to which is attached a collar, 0. D D represent the extinguishing-caps, attached to the bent leversa, to the lower ends of which are secured the weights 0 c.

-The levers 'a bend outward and upward from the pivot, in such a manner that, when the lamp is in an upright position, the pendent weights will cause the caps to fall away from the wick-tube. In small lamps,

these-caps will serve the purpose of a burner. Should the lanip, however, receive a fall, or be overset, one or both of the caps will be :thrown over the top of the wick,--extingnishingthe flame.

E represents thegange-chamber, enveloping the wick, withint-he bowl of the lamp, and designed to prevent theaoccss of flame thereto.

WVhen this chamber is combined with the automatic extinguishing-caps'abOve described, it is thought that the lamp will be rendered perfectly safe,=even though the bowl should be brokento pieces.

Sometimes I design to dispense with the sliding collar on the wick-tube, attaching the bent levers innuediately to the latter.

Where the' sliding collar is used, a small set-screw is inserted through it, designed to secure the collar to the wick-tube whenlit is adjusted to the proper height.

By placing the weights belowthe fulcrum-pin, there is no danger of either cap falling inward over thewick and putting out the flame, unless the lamp be intentionally very much inclined, or subject to a considerable shock. The ordinary shaking of a railroad car, ornnsteadiness in the hand of the person carrying the lamp, will not throw the cap over the lamp. Furthei by placing the weight below, a greater leverage may be obtained without diminishiugthe distance from the center of gravity.

I amaware that the extinguishing-caps have been weighted above the fulcrum, and, therefore, I do not broadly claim such. caps but What I claim as my invention, and desire to secure by Letters Patent, is-- In a lamp-burner, the arrangement of the extinguishing-capsv D -D, bent levers a a, and pendent' weights 0 c, as and for the purposes herein shown and described. 7

In testimony that I claim the above, I have hereunto snbscribed my name in the presence of two witnesses.

JNO. HUGHES.
