SAFETY-LAMP.

Specification of Letters Patent No. 11,730, dated September 26, 1854.

'T 0 all tf1/Lomi?? may concern Be it known that I, CHARLES ROBERT LANmIANN, of the city, county, and State of New York, have invented certain new and useful Improvements in Lamps for` Burning Camphine or other Explosive Fluids; and l do hereby declare the following to be a full description of the same.

The nature of my invention consist-s in arranging in the globe of the lamp ar pendulum or swinging shaft, which, when in a vertical position, supports an extinguisher rod, extending up through the wick tube, and having an extinguisher button on the head of it. Also on the extinguisher rod is attached a reacting spiral spring which is intended for holding the point of the rod firmly in its seat on the head of the pendu` lum or swinging shaft, and also for the pur pose of reacting the extinguisher rod, to extinguish the lamp instantly on the lamp fall ing, and the weight on the lower end of the pendulum or swing shaft vib-rating so as to allow the point of the extinguisher rod to slip past the upper end of the pendulum, and consequently allow the button to come down upon the head of the wick to extinguish it. But to describe my invention more particularly I will refer to the accompanying drawings forming a part of this schedule, the same letters of' reference wherever they occur referring to the same parts.

Letter B, is a vertical cut section of a camphine lamp having the safety apparatus in combination therewith.

Letter A, is a vertical cut section of a fluid or spirit gas lamp.

Letter B, is the lamp which is made in the ordinary way, and is represented as supported by a standard by means of an adjust-ing `screw. In the neck or wick tube of the lamp is a balance pole or extinguisher rod Figure 2. This rod, when the lamp is in burning order rests on the top of a pendulum or swinging shaft Fig. 1c arranged in the globe of the lamp on an axle Fig. l" and having a weight Fig. l*l attached to its lower or pendent end. When the lamp is in a vertical position, this pendulum or swinging shaft is also vertical, but on the lampbeing tilted or overset the` weight Fig. 1EL falls to the lower side of the lamp, releasing thereby the head of it, Fig. la from the lower end of the balance pole or extinguisher rod Fig. 2 so Aas to allow the extinguisher cap Fig. 3 to drop down upon the head of the wick Fig. 5 in consequence of the reaction of the spring Fig. 4 upon the extinguisher rod.

It will be obvious from this self adjustment of the extinguisher that no accident can happen in the event of oversetting the lamp-and that the application of the same arrangement of mechanism may be applied to fluid lamps or other lamps using explosive compounds with equal facility and utility.

Having now described my invention I will proceed to state what I claim and desire to secure by Letters Patent of the United States.

The use of the pendulum or swinging shaft, in combination with the balance rod (having reacting spring in connection therewith), and camphine or other explosive fluid lamp, substantially as hereinbefore set forth.
