AUTOMATIC LAMP BXTINGUISHERL No. 365,734. I Patented June 28, 1887 UNITED STATES AT OFFIC JOHN C. DAGGETT, OF BOSTON, ASSIGNOR OF ONE-HALF TO CHARLES H. COLBURN, OF MILFORD, MASSACHUSETTS.

AUTOMATIC LAMP-EXTDNGUISHER.

spreerrrea'rron forming part of Letters Patent No. 365,734, dated June as, 1887.

Application filed February 19, 1887. Serial No. 228,184. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN C. DAGGETT, of Boston, county of Suffolk and State of Massachusetts, have invented an Improvement in Automatic Lamp-Extinguishers, of which the following description, in connection with the accompanying drawings is a specification, like letters on the drawings representinglike parts.

This invention has for its object to provide a lamp-extinguisher with means for operating it automatically, whereby the flame of a lamp may be extinguished whenever the lamp is tipped materially relative to its support, or is overturned, as in-case of accident.

The invention consists in anautomaticlampextinguishing device constructed and arranged substantially as hereinafter particularly set forth and claimed.

Figure 1 shows in side elevation a lamp, its extinguisher, and means for operating the extinguisher automatically whenever the lamp is moved with relation to its support; Fig. 2, an enlarged top viewof'a lamp-burner and its extinguisher; and Fig. 3, a sectional detail to be referred to. I

The lamp-body a, contained in any usual lamp support or bracket b, the burner c and its chimney d, are and maybe of any usual construction.

The lamp-extinguisher herein employed consists of a sleeve, 2, (see Figs. 2 and 3,) surrounding or inclosing the wicktube 3, and having at its upper end a lip or cap, 4, pivoted to the sleeve and pressed against one side of the wicktube 3 by a spring, 5, when the sleeve is at its lowermost position, though any other form of lamp-extinguisher of itself, and separately considered, may be used in connection with my invention of operating mechanism following.

The sleeve is provided at each side with a pin, 6, against the under side of which bears a spring, 7, said spring being held depressed by the hooked end 8, of a pivoted operatinglever, 9, so that when the said lever is turned on its pivot in the direction of the arrow, Fig. 1, the hooked end 8 releases the spring 7 which latter, by striking against the pin 6, raises the sleeve 2 above the termination of 50 the wick-tube 3, allowing the spring-controlled lip or cap 4 to close the upper end of the sleeve, concealing the wick and extinguishing the flame. One end of the cord f is connected with the outer end of the projecting lever 9, and after passing outwardly through the eye 12 its opposite end is attached to a weight or ball, 9. V

The weight or ball 9 is supported in :a shallow stationary bracket or support, h, secured to one side of the lamp-support, or to any usual convenient place, the location of the support being such as to keep the cord f slack.

be seen, therefore, that the operation of the extinguisher for the extinguishment of the flame is not wholly dependent upon the weight merely, but that the spring is an act ive and essential factor in the automaticity of the operation, thereby insuring quick and effective. action on the part of the extinguish ing device.

I do not desire to limit my invention to any particular form of weight or weightsupport.

I claim- A lampextinguisher of substantially the construction hereinbefore set forth, combined with pin 6, extending laterally from the'extinguisher, spring 7,arrauged below said pin, and in engagement therewith, catch-lever 8 9, normally engaging the spring and restraining it from acting upon the pin, a cord and weight connected to said catch-lever to disengage it from the spring when the lamp is displaced, and a support for the weight, rendering it under ordinary conditions normally in active, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN G. DAGGETT.
