LAIVIP BURNEFL SPECIFICATION forming part of Letters Patent No. #533,065, dated February 23, 1904.

Application filed July 25, 1903. Serial No. 166,977. (No model.)

To all whom it may concern]! Be it known that we, WILLIA GUN-NELL the county of Allegheny and State of Penn.- sylvania, have invented certain new and useful Improvements in Lamp-Burners, of which the following'is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in lamp-burners, and relates more specificallyto that type of burners employed in connection with lamps of the type employing kerosene as a fuel.

The present invention has for its object to provide means for automatically extinguishing the light upon the lamp being turned over or upset whereby to prevent the explosion of the fuel, and the invention contemplates the provision of means for this purpose which may be employed as an extinguisher and snuffer for the light if used when the lamp is in its upright position.

Briefly described, the invention comprises a perforated plate provided with pockets in each of which a spherical body is placed. A pair of snuffing-wings are pivoted one at each side of the wick-casing, and these wings carry flaps or doors, which lie normally over the pockets in the perforated base. Upon the lamp being overturned these spherical bodies engaging against the flaps or doors move the snufling-wings overthe light, whereby to extinguish the same. Upon the lamp being returned to its normal position the snufiingwings also assume their normal position. A

pivoted lever is provided by means of which the snufiing-wings can be actuated to force the same toward each other, whereby to extinguish the light when the lamp is in the upright position.

All of the above construction will be hereinafter more. fully described, and specifically pointed out in the claims, and in describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a detail side elevation of a burner constructed in accordance with our invention, showing the burner-cap open to better illustrate the extinguishing mechanism. Fig. 2is a top plan view of the same. Fig. 3, is avertical sectional view of a part of the burner. Fig. 41 is a detached detail perspective view of one of the snufling-wings. Fig. 5 is a detached detail perspective view of the perforated base-plate. Fig. 6 is a transverse vertical sectional view of said plate, and Fig. 7 is a detached detail perspective view of the actuating-lever for operating the snufiingwings by hand.

.Our invention is adapted to be employed either in connection with the ordinary type of burner to be attached thereto or to construct a burner in accordance with the invention. The burner-body 1 and the burner-cap 2 are therefore of the usual form of construction.

To apply the device to the burner now in use, we remove the perforated top plate of the burner and place on the burner in lieu thereof a perforated plate 3, which we secure in any suitable manner. This plate is provided with a wick-receiving opening at, and at each side of this opening the material is forced downwardly to form segment-shaped. pockets 5, which are adapted to receive spherical bodies 6, that are of less diameter than the depth of the pocket, as clearly seen in Fig. 6 of the drawings. In the strip 7 of the plate 3, which lies between the pockets 5, we provide parallel slits 8, which receive the lugs 9 of the perforated flaps or doors 10, which flaps or doors are preferably constructed integral with the snuffing-wings 11. These snuffingwings are made with side and top flanges, whereby when they are closed together, as shown in dotted lines in Fig. 1 of the drawings, they will snuff the light in order to extinguish the same. As the wick-receiving tube 12 of the burner usually has a lap-joint at one side thereof, we cutout one of the-wings 11, as seen at 14 in Fig. 4, whereby to allow the said wing to close against the wick-receiving tube. need to be provided with this cut-out portion, as the seam of the wick-receiving. tube is only at one side thereof.

In operation automatically it will be observed that when the lamp is turned or upset the spherical body 6, striking against the flap or door 10, will raise the same, as seen in dotted lines in Fig. 1, whereby to move the snufling-wing against the flame to extinguish the same, as also seen in dotted lines in Fig. 1. It will of course be evident that when the lamp is turned to one side only one of the wingsnamely, the uppermost onemoves over in engagement with the light to extinguish the same. In order, however, to provide extinguishing means for the light when the lamp is in the upright position, and thus obviate the danger of exploding the oil by blowing down the chimney of the lamp, we provide a lever 15, pivotally hinged on a hook 16, carried by the body 1. This lever at its inner end is provided with a pair of parallel slits forming prongs 17, which straddle the wicktube 12 and act as a guide for the lever to prevent a lateral or swinging movement thereof at its pivot. The material between the slits is struck up to form an arm 18, carrying side lugs 18, cut out from the prongs 17, which are adapted to engage between the lugs 9 of the respective flaps or doors, and when the outer end of the lever 15 is depressed to actuate the flaps or doors it elevates the same to the position shown in dotted lines in Fig. 1, closing the snuffing-wings over the wick-tube. Upon pressure on the outer end of the lever being relieved the same returns tov its normal position and the weight of the wings and flaps or doors returns the same to their normal position, as shown in full lines in Fig. 1 of the drawings. The overturning of the lamp immediately and automatically moves oneor the other of the snuffing-wings into engagement with the burning end of the wick and smothers and extinguishes the light, and when desired to extinguish the light with the lamp in the upright or normal position the mere depression of the lever 15 closes the snuffingwings around the light to extinguish the same.

While we have herein shown and described our invention in detail, yet it will be evident that in the practice thereof various changes may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

' 1. In a device of the type set forth, the combination with the burner-body, a perforated top plate having a central portion provided with a wick-receiving slot and parallel slits at each end of the said central portion, said plate having pockets formed at each side of the central portion, a pair of snuffing-wings comprising horizontal portions normally closing the said pockets, an upwardly-extending angularly-disposed portion adapted to engage the wick, said wings having lugs extending in the parallel slits of the perforated plate,

means in the pockets adapted upon upsetting of the lamp to engage the horizontal portion of the wings to actuate the same, and a lever having forked ends with an upwardly-extending portion formed centrally of said ends, said portion being adapted to engage the lugs of the wing when the lever is depressed.

2. In a deviceof the type set forth the combination of the burner-body and the perforated top plate having a central portion provided with a wick-slot and parallel slits at each end of the said central portion with pockets formed at each side of the latter, of a pair of snufling-wings comprising horizontal portions for closing the pockets, and upwardlyextending angularly-disposed portions adapted to engage the wick, said wings having lugs engaging in the parallel slits of said plate, spherical bodies in the pockets adapted upon upsetting of the lamp to engage the horizontal portion of the wings to actuate the same, a lever pivotally hinged to the burner-body, said lever having forked ends straddling the wick-tube, and a central upwardly-extending arm located between said forked ends and carrying at its forward end side lugs adapted for engagement with said lugs of the wings upon depression of the outer end of said lever to actuate said wings.

In testimony whereof we afiix our signatures in the presence of two witnesses.
