LAM P-EXTIXNGUISHER.

SPECIFICATION forming part of Letters Patent No. 749,061, dated January 5, 1904. Application filed July 6,1903. Serial No. 164,462. (No model.)

To all whom it may concern:

Be it known that I, HARRY DAIN HINKS, a subject of the King of Great Britain, residing at Great Hampton street, Birmingham, England, have invented certain new and useful Improvements in Lamp Extinguishers, of which the following is a specification.

My invention consists of the improvements hereinafter described in lamps burning light or volatile oils, the said improvements having for their principal object to facilitate the extinguishing of the lamp.

In carrying my invention into eifect I construct and arrange the parts of the lamp in the manner hereinafter described, and represented in the accompanying drawings, of which Figure 1 represents in vertical section the lamp reservoir and burner, the parts being in their normal positions. Fig. 2 is a similar View to Fig. 1, but showing the lamp tilted to the angle which effects the automatic extinguishing of the lamp. Fig. 3 represents a portion only of the burner of the lamp with part in section or brpken away, the said section being taken in a plane at right angles to the section, Figs. 1 and 2.

The same letters of reference indicate the same parts in the several figures of the drawlngs.

The wick-tube a of the burner is arranged at an angle of about sixty degrees to the horizontal, as will be best seen by reference to Fig. 1. The upper end of the inclined wicktube a terminates under or approximately under the middle slot 17 in the cone b of the burner, through which slot 6 the flame of the lamp rises,as is usual. The inclined wicktube a at its lower end communicates with the oil-reservoir c at one side, as is seen in Figs. 1 and 2. a

On the inclined wick-tube a, a sliding extinguisher-tube d is arranged, the upper end of which is so shaped that when it is raised on the wick-tube a in either of the ways hereinafter described its upper end comes in contact with the under side of the unslotted part of the cone b, as is represented in Figs. 2 and 3-and indicated in dotted lines in Fig. 1, and practically completely cuts off the supply of air to the burning wick, and thereby'extinguishes the flame of the lamp.-

It will be noted that the longitudinal axis of the wick-tube is disposed at an angle relative to a vertical plane passing through the slot in the burner-cone, and the extinguisher is slidably arranged on the wick-tube, the arrangement being such that when the extinguisher-tube is raised it will abut the imperforate portion of the burner-cone, and thereby out off the supply of air to the wick, and thus extinguish it.

To permit of the extinguishing of the lamp when desired by hand, a hand-lever e is arranged at that side of the burner toward which the wick-tube a inclines, the inner end of the said lever 6 being hinged or jointed to the lower end of the extinguisher-tube d.

The middle part of the lever 6 Works in a slot in the side of the burner. By pressure of the finger on the outer end of the lever 6 it is made to take the dotted position indicated indotted lines in Fig. 1, and thereby raise theextinguisher-tube d into its extinguishing position on the wick-tube a.

In order to efiect the automatic extinguishing of the lamp when the same is tilted or I upset, the bottom of the oil-reservoir o is made, preferably, in the form of an inverted hollow truncated cone, and arranged therein is a metallic ball or sphere f, having a rod f projecting from its top, the upper end of which passes through a hole in the parts of the burner constituting the top of the reservoir c and bears on the under side of the inner end of the lever e. In the normal positions of the parts the ball f rests on the flat bottom of the inverted conical cup-like lower part of the reservoir 0, and consequently it remains inactive until the lamp is upset or tilted. When the lamp is tilted until any portion of the conical side inclines downward, as is represented in Fig. 2, the ballf slips down the downwardly-inclined side, the said ballf and its rod f rising with respect to the burner. The upper end of the rod f acting on the under side of the inner end of the lever e, thereby raises the said lever and extinguisher-tube d intoits extinguishing position, as is represented in Fig. 2, and consequently extinguishes the lamp, as is hereinbefore described.

In order to prevent the wick in the oil-reservoir from interfering with the action of the ball f when the lamp is tilted or upset, the wick may be preserved at one side of the said reservoir by means of a depending plate or diaphragm c By the method of extinguishing described the objectionable odor which usually arises from the wick immediately after it is extinguished in the ordinary way is prevented. Further, although I have described and represented my invention as applied to a lamp having a single fiat wick only, I wish it to be understood that it is equally applicable to lamps having duplex or various other forms of burners.

Having now described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. In alamp, the combination with a wicktube the longitudinal axis of which is dis-- posed at an angle relatively to a vertical plane passing through the slot in the burner-cone, and an extinguisher-tube slidably arranged on the wick-tube, said wick-tube being arranged at such an angle that when the extinguisher-tube is raised it will abut the imperforate portion of the burner-cone and there by out oi the supply of air to the wick, for the purpose specified.

2. In a lamp, the combination with a wicktube the longitudinal axis of which is arranged at an angle relatively to a vertical plane passing through the slot in the burnercone, an extinguisher-tube slidably arranged on the wick-tube, and means for raising the extinguishertube, the arrangement being such that when the extinguisher tube is raised its end will abut the imperforate portion of the burner-cone and thereby cut ofi the supply of air to the Wick, for the purpose specified.

3. In a lamp, the combination with a wicktube the longitudinal axis of which is arranged at an angle relatively to a vertical plane passing through the slot in the burnercone, of an extinguisher-tube slidably arranged on the wick-tube, and means for automatically raising said extinguisher-tube when the lamp is tilted to one side, the arrangement being such that the end of the extinguishertube when raised will abut against the imperforate portion of the burner-cone and cut ofi the supply of air to the wick, for the purpose specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- HARRY DAIN HINKS. Witnesses:

RICHARD SKERRETT, ARTHUR JOHN POWELL.
