EXTIINGUESHER MECHANlSM FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 391,712, dated October 23, 1 888.

Application tiled Juno 7, 1888. Serial No. 276,313. (No model.) Patented in England January 18, 1888, No. 808.

.To all whom it may concern:

Be it known that I, JOSEPH HINKS, of the firm of James Hinks & Son, (Limited,) of Birmingham, in the county of Warwick, Eng land, a subject of the Queen of Great Britain, have invented Improvements in or Connected with Extinguisher Mechanism for Lamps, (for which I have obtained Letters Patent in Great Britain, No. 808, dated January 18, 1888,) of which the following is a specification.

This invention has for its object to provide novel mechanism for automatically extinguishing lamps in case of accidents; and to such end the invention consists in the combination of devices hereinafter described and claimed.

Figurel of the accompanying drawings represents in side elevation, partly in section, Fig. 2 in plan, and Fig. 3 in end elevation, partly in section, the duplex burner of an oil-lamp to which extinguishing mechanism constructed according to my invention is ap plied. Fig. 4. represents the same view as Fig. 1, with the extinguishers raised for extinguishing the flames by the action of the finger upon the pendent weight. Fig. 5 exhibits the positions of the parts of the extinguishing mechanism when the lamp is upset and the said extinguishing mechanism automatically brought into action for extinguishing the flames, and Fig. 6 represents an end elevation of the burner with the extinguishing-flaps in their raised positions.

I will first describe the extinguishing mechanism for the duplex burner.

a a are the two wick-cases of the duplex burner, and b b are the extinguishers sliding upon the wick-cases.

b b are the jointed flaps at the tops of the extinguishers.

c is the conical pendent weight of the extinguishing mechanism, suspended, when in its normal position, by the head of the stem 0 engaging with an eye or hole in the fixed bracket d, carried by the lamp-burner.

cf is the ring-lever turning on the joint g, the ring e of the lever having the figure ofpart ofa hollow cone or hood to bear upon or embrace the conical weight 0.

h i is the second lever turning on thejoint 7c, the inner long arm, 11, of which second lever is connected with and lifts the extinguishers b b. The inner short arm, f, of the ring-lever cf bears upon the short outer arm, h, of the second lever, h t, and the long arm, 11, of the said second lever passes through a slot in the cross piece of the sliding guide Z, situated between and connected to the two extinguishers b b. The two extinguishers b b and their flaps b b are without springs, the lifting of the said extinguishers,when the ring-lever ef is lifted by hand, as in Fig. 4, or by the upsetting of the lamp, asin Figs. 5 and 6, being effected by the action of the second lever, h i, upon the extinguishers. When the pendent weight 0 takes its normal position on the removal of the pressure from it, or by the restoring oi thelamp to its upright position, the sliding extinguishers b b descend by their own weight. The movable flaps I) b may either close upon the tops of the wick-cases a a, to extinguish the flames by the action'of springs when the extinguishers are lifted, or the said flaps b I) may be operated upon by inclines in the manner represented in the drawings-that is to say, the end of each jointed flap b" is provided. with an incline or inclined arm, m, the lower ends of which arms cross one another. Between the two inclined arms m m is a fixed upright, n, the top of which is bent atlright angles and constitutes a stop, 1). \Vhen the sliding extinguishers b b have been nearly lifted to their full extent by the action of the second lever, h i, the crossing ends of the two inclined arms m m on the extinguishing-flaps strike against the stop 0. The continued motion of the sliding extinguishers causes the said inclined arms to separate by the action of the stop 19 upon them. The flaps b b are thereby turned upon their joints and made to collapse upon the wicks and extinguish the flames, as seen in Fig. 6.

The construction and combination of parts described, and represented in Figs. 1, 2, 3, 4, 5, and 6, may be used with lamps having single wicks. When applied to singlewick lamps, the inner arm of the second lever acts upon a projection at the back of the single extinguisher, and the stop p acts upon the single incline or inclined arm of the extinguisher-flap.

I wish it to be understood that I lay no claim to the use of a pendent weight and ringlever, excepting as modified and used in the manner and in coiijunction with the appliances hereinbefore described and represented.

Having now particularly described and ascertained the nature of my invention and the manner of performing the same, I declare that I claim as my invention The combination, with a lamp-burner and the extinguishers having jointed flaps b and arms m, crossing each other, of the arm it, having the stop 19, thesecondary lever pivoted between its ends and connected at its inner extremity with the extinguishers, the pivoted mainlever having its inner end engaging the secondary lever and its outer end provided with a ring", a stationary bracket fixed to a part of the burner and projecting outward therefrormand a weight having a vertical rigid stem loosely 15 passing upward through the ring and the bracket and pendulous from the latter, substantially as described.
