LAMP OR LANTERN EXTINGVUISHERQ.

SPECIFICATION forming part of Letters Patent No. 591,608, dated October 12, 1897.

Application file February 8, 1897. Serial ITO-622,526. (No model.) Patented in Oanada April 10, 1897, No. 55,587-

To all whom it may concern;

Be it known that I, DANIEL THOMAS KEN- NEDY MOEWEN, a subject of the Queen of Great Britain, residing in the township of Roxborough, in the county of Stormount, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Lamp or Lantern Extinguishers, (patented in Canada April 10, 1897, No. 55,587,) of which the following is a specification.

My invention relates to improvements in lamp and lantern extinguishers; and the object of my invention is to provide a simple device by which a person is enabled to extinguish the light without the necessity of removing the chimney; and it consists in the construction and arrangement hereinafter described, and pointed out in the claims.

Thedrawing represents a perspective view of a lantern having a portion broken away to exhibit the construction of my device.

On reference to the drawing, A A are the tubular supports of the lantern; B, the chim- .ney, which is suitably held at H and rests on the ordinary perforated bottom C.

E is the oil-reservoir,which is provided with a raised portion E.

F is the burner.

G is a hollow sphere or ball, preferably made in two halves, suitably fastened to the raised portion E, and is provided with a hole 0.

g is a tube which is riveted to the side of the ball G at 0 over the hole 0 and extends up through the perforated bottom 0 to within any desired distance of the top of the wick O. The upper end j of the tube g is bent at right anglesto the main portion and is gradually made smaller toward its end by a tapered portion D.

V is a small hole at the end of the tapered portion D.

I isa rubber bulb which fits the interior of the ball G and is provided with a neck h, which extends any suitable distance within the tube g.

Lis a fiat spring, semicircular in shape, suitably fastened to the interior of the ball G by the rivet Z and directly opposite a hole i. In its normal position the spring L rests between the bulb I and the wall of the ball G.

J is a pin passing through the hole 1' and provided with a button-shaped head K. The other end of the'pin J is provided with a rivethead M and abuts against the spring L.

Having now described the, principal parts involved in my invention I shall describe its operation.

When it is desired to extinguish the light, the pin J is depressed by pushing on the head K. This depresses the spring L, which in turn depresses the bulb I, thereby expelling part of the air into the tube g, from which it is expelled against the flame in a strong current or draft, thereby extinguishing the flame. When the head K is released, it will be easily understood that the spring L will force the pin back into its normal position and the bulb will be reinflated by atmospheric pressure, the air flowing back into the tube through the opening V.

It will be noticed in the drawing that I have placed the top of the tube J directly op- I posite the end of the top of the wick O and consequently the flame. I find by this position that I get a much more positive action of my device-that is, the whole flame is acted uponwherea's if it were placed at right angles to the flame only a portion of the flame at a time would be acted upon and the result would not be satisfactory.

From the foregoing specification it will be seen that my device is cheaply made and is of positive action. It is always convenient to get at and does away with the great disadvantage of having to remove a hot chimney when the light is to be extinguished.

What I claim as my invention is- 1. In a device of the class described, in combination, a hollow metal ball, an internal rubber bulb having communication with a metal tube leading from the ball up to within suitable distance of the flame, a flat semicircular spring suitably secured to the inside of the sphere and designed to normally rest close to the bulb, a pin connected to the spring, ex-

tending out through a hole in the hollow ball bination of the ball, bulb situated Within such ball, spring suitably held and normally restin g close to such bulb, pin for depressing such spring so as to expel air from the bulb the I tube 9 provided at its upper end With a gradually-tapered portion D which terminates in a small hole V from which the air is expelled from the tube against the flame, as andfor the purpose specified.
