LAMP-EXTING UISH ER.

SPECIFICATION forming part Of Letters Patent N0. 496,646, dated May 2, 1893.

Application filed June 17, 1892. Serial No. 437,070- (No model.)

To all whom it may concern.-

Be it known that I, EDWARD P. GOODRIOH, a citizen of the United States, residing at Ypsilanti, in the county of Washtenaw and State of Michigan, have invented a new and useful Lamp-Extinguisher, of which the following is a specification.

This invention relates to certain new and useful improvements in lamp extinguishers adapted also to be used for trimming the wick, and consists in the construction and novel combination and arrangement of the parts thereof as will be more fully hereinafter described and claimed.

The object of this invention is to provide a device of the character set forth of simple form, which is adapted to be applied in connection with any form of burner and be used both as an extinguisher or as means for trimming the end of the wick.

In the drawings: Figure 1 is a perspective view of a burner with the dome or cap raised and showing the improved device applied in connection therewith. Fig. 2 is a longitudinal vertical section of the device. 7

Similar numerals of reference indicate corresponding parts in both theviews.

Referring to the drawings, the numeral 1 designates the rim supporting the perforated draft-plate 2, and a depending collar 3, adapted to be fitted to the lamp-body and having a dome or cap 4:. A wick-tube 5 extends upward centrally through said parts and has openings 6 in one side thereof for the entrance of toothed wheels 7 adapted to engage the wick and feed the same upward and downward through said wick-tube 5. Said wheels 7 are carried by a horizontally-disposed shaft 8, extending through the lower portion of the burner-frame and journaled therein in the usual manner, and is provided at its outer end with a turning-disk 9.

On each side of the wick-tube 5, where it projects above the perforated draft-plate 2, openings or slots of slightly elongated form are constructed in the said draft plate 2, and through these slots movably extends the improved attachment, and the remaining portion of thelatter is entirely concealed beneath the draft-plate 2, thereby forming a neat construction and obviating a marred or broken appearance of the burner. The dome 4 is adapted to close down over the said attachment and the wick-tube and thereby entirely conceal the attachment from exterior View.

The improved attachment consists of a wire frame 10, of substantially-rectangular form having an arm 11, with an eye 12 therein surrounding the said shaft 8, near one end there of, and high enough to freelypass over the top-portion of the wick-tube 5. The opposite arm 13 of the attachment extends downward at a slight angle of inclination and then outward through the lower portion of the burnerframe at a greater angle as at 14:, and is coiled loosely around the shaft 8, as at 15. The free outer end of the said frame is bent upward adjacent to the disk 9 into the form of an operating handle or arm 16, whereby the device may be operated independently of the motion of the said shaft 8.

The attachment is formed of wire of a suitable nature, and may be operated to extinguish the light, together with the operation of the shaft 8, or independently of the movement of said shaft, and may also be employed to trim the end of the wick by being forced suddenly across the upper end of the wicktube.

The coiled part of the attachment, as at 15, aroundthe-shaft 8 produces a slight binding action on the said shaft and causes the attachment to move with the shaft when the latter is turned in one direction, and when the wick is raised the attachment is sustained in immovable position by having one side or leg thereof bear against one of the end walls ofthe slot through which it passes down to the lower part of the burner. When the wick is lowered the upper end of the attachment is forced thereagainst by a slight spring-pressure, owing to the coiled construction, that imparts a slight resiliency to the device or attachment; and this pressure continues until the wick is entirely lowered below the upper end of the wick-tube or the level of the upper end of the attachment, when the latter moves across the wick over the top of the wick-tube and thereby acts as an extinguisher. By

means of the handle 16, which is a continuation of the device, disposed in avertical plane, the attachment may be independently moved across the upper end of the wick-tube and over the end of the wick without operating the shaft in order to trim the wick. This operation is very simple, and the attachment entire may be readily applied to any form of burner employing a shaft as set forth.

The duplex operation of the device is attained by the attachment thereof with the shaft, the said attachment being made secure enough to cause a movement of the attachment simultaneously with the movement of the shaft. This operation will be especially useful in trimming the wick, as it can be accomplished immediately the wick is lowered by turning the shaft 8, and when the upper end thereof comes into line with the upper end of the wick-tube.

In some cases it may be found desirable to omit the handle 16, but I find that the use of this additional feature enables the attachment to more efficiently perform its functions.

Having described the invention, what is claimed as new is In combination with the wick-tube, the wick-raising shaft, and the draft-plate of a lamp-burner, of a combined extinguishing and wick-trimming attachment consisting of a substantially rectangular frame having the upper end thereof projecting above the draftplate and the height of the wick-tube and the lower part thereof concealed beneath thedraftplate and connected at opposite sides to provide a positive action at all points across the wick, one leg of the said rectangular frame being loosely mounted on the wick-raising shaft and the opposite leg deflected at a downward and outward oblique angle and coiled around the wick-shaft in such manner as to produce a frictional binding when the latter is turned in one direction, the coiled portion of the attachment terminating in a handle that is disposed vertically and continuous thereof, whereby the attachment may be 0perated independently of the movement of the shaft, substantially as described.

In testimony that I claim the foregoing as my own 1 have hereto affixed my signature in the presence of two witnesses.

EDWARD P. GOODRIOI-I.
