SPECIFICATION forming part of Letters Patent No. 380,858, dated April 10, 1888.

Application filed May 4, 1887. Serial No. 237,091. (No mo e1.l

To aZZ whom it may concern:

Be it known that I, Enson L. BRYANT, of Ansonia, in the county of New Haven and State of Connecticut, have invented a new Improvement in LampExtinguishers; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same,

and which said drawingsconstitute part of this specification, and represent, in

Figure 1, a vertical section ofa burner, showing one side of the extinguisher; Fig. 2,a ver' tical section of the burner, showing the oppoi5 site side of the extinguisher; Fig. 3, a section of the burner, showing edge view of the extiir guisher; Fig. 4, a top view of the burner, showing the extinguisher in the open position; Fig. 5, a vertical section through the wicktube and extinguisher, showing the extinguisher in the up-elosed position; Fig. 6, the extinguisher as applied to two-wick burners; and Figs. 7 and 8, modifications in the engaging device between the extinguisher and the wick-tube.

Thisinvention relates to an improvement in that class of extinguishers for lamp-burners which surround the wick-tube, and are adapted to be closed over the upper end of the burner by an upward movement of the extinguisher. in the more general construction of this class of extinguishers they are of tubular character, corresponding to the wiclctube, one side being hinged so as to fall over the upper end of the wiclotube upon or against the opposite side 5 of the extinguisher, and so that the hinged part is held in the open position by the wicktube itself, and so thatas the extinguisher passes above the wick-tube the hinged part rides over the edge of the wick-tube and closes o at a point very near or close down upon the upper end of the wick-tube, and so as to substantially rest or bear upon the wick.

The object of my invention is the construction of an extinguisher of this character, so

that it may pass at a considerable distance above the end of the wick-tube before the closing commences, and whereby the closing is produced at a point so high above the wicktube as not to interfere with or be affected by the wick itself.

A represents the wick-tube of a common lamp-burner.

The extinguisher is composed of a plate, B, on one side of the wick'tube. Its ends are turned around so as to embrace the sides of the wicktube, as seen in Fig. 3, and so that the plate may slide freely up and down upon the wick-tube, the wick-tube serving as a guide for the up-and-down movement of the plate B upon the opposite side of the wicktube. The closing part C of the extinguisher is hinged to the plate or part B by trunnions a, formed on the ends of the part C,extending into corresponding ears,b,projecting from the plate B, as seen in Figs. 2 and 3. From the part C one or more downward projections, 02, are formed, adapted to bear against the wicktube, as seen in Figs. 2 and 3.

In the normal condition of the extinguisher it stands, as seen in Figs. 1 and 3, at a point when the upper edge of the two parts B and C stands flush with or below the upper end of the wick-tube A. At a point substantially in line with the axis of the hinge or below, the part C is constructed with an inward projection, 6, and near the upper end of the wicktube. The side of the tube next the part 0 is constructed with an outward projection, f, which stands in the path of the projection e on the part C when the extinguisher is raised, and So so that while the twoparts of the extinguisher will stand in their open position in rising, as seen in broken lines, Fig. 3, so soon as the projection c of the part C comes in contact with the projection f on the tube the further upward movement of the extinguisher will cause the part C to be turned toward and so as to close upon the part B, as seen in Fig. 5; but until the extinguisher reaches this closing position the projection f on the wick-tube o bears against the inner surface of the part C above the tube and serves to p revent its closing until it reaches the said extreme up position. Under this construction and arrangement it will be observed that the closing does not 5 commence until the extinguisher has passed to a considerable distance above the end of the wick-tube,and so that there is no possible contact between the upper end of the wick and the extinguisher. IOO

In case of the gradual and early closing of the extinguisher, which I have described as existing in previous constructions, there is liability of the projecting wick interfering with the closing movement of the extinguisher, so as to only produce a partial movement, the result of which is that while the flame maybe extlnguished the fire upon the wick will continue for some time, causing a disagreeable smoke; but because of the'construction which I have described, whereby the closing cannot commence until the extinguisher is so far above the wick as not to be interfered with, the closure is made perfect and independent of the wick, and consequently not only is the flame extinguished, but the fire upon the end of the wick, and the smoke incident to the earlier closing of the extinguisher is avoided. After the flame has been extinguished the extingulsher may be returned, and instantly upon the commencement of the return the hinged part is disengaged from the projection on the wick-tube, which closed it. That projection serves to open it immediately, and the extin guisher descends without rubbing upon the end of the wick, which must occur in the earl1erclosing extinguisher which I have described.

To impart to the extinguisher its up-anddown movement, I arrange a lever, D, upon a fulcrum, E, in the burner, and so as to swing 1n a vertical plane parallel with the plane of the wick-tube, one arm of the lever extending outward to form a handle, by which the levermay be operated, the other arm extending inward and engaged with the plate B through a slot, F, formed therein, as seen in Fig. 1, and so that by turning the handle part downward the extinguisher will be raised, or in a reverse movement the extinguisher will be drawn downward.

I have described and illustrated the invent1on as applied to a single-wick burner; but it may be applied to a duplex burner, as seen in Fig. 6, in which A A represent the two wicktubes, one extinguisher such as I have described being applied to each wick-tube. In this case the lever should work between the two extinguishers upon a connection, G, so that the movement of the lever simultaneously operates both extinguishers.

I have represented the engaging devices between the hinged part 0 of the extinguisher and the wick-tube,whereby the said part0 is closed or opened, as an outward projection on the wick-tube and inward projection from the part 0. the engagement between the wick-tube and the hinged part may be otherwise producedsay as by making a vertical groove in the wick-tube, as seen in Fig. 7, into which a projection on the hinged partwill work. This construction, however, simply forms a shoulder which corresponds to and is substantially the same as the projection f,which I have described, on the wick-tube; or, as seen in Fig. 8, the hinged part 0 may be constructed with a vertical groove and the projection f on the wick-tube work therein. I therefore do not wish to be understood as limiting myself to any specific means for engaging the wick-tube and the hinged part of the extinguisher as the extinguisher approaches its extreme up position; but

lVhat I do claim is- 1. In combination with the wick-tube of a lamp-burner, an extinguisher composed of the plate B upon one side of the wick-tube and the part 0 upon the opposite side of the wicktube, hinged to the plate B, the said parts adapted to be moved together up and down upon the wick-tube as a guide, the part 0 and the wick-tube, upon their adjacent faces, constructed the one with a projection toward the other, and the said other constructed to engage said projection as the extinguisher approaches its extreme up position,substantially as described.

2. The combination of the wick-tube, the plate B, arranged upon one side of said tube and the part 0 upon the other side of the tube, hinged to the said part B, the said parts B and 0 adapted to be moved up anddown upon the wick-tube, the part 0 constructed with one or more projections, d, downward below the line of the hinge, and so as to bear upon the surface of the wick-tube, and an engaging device between the wick-tube and the said part 0, adapted to engage the said part 0 at a predetermined point in its rise, and thereby impart the closing movement to the said part 0, substantially as described.

3. The combination of the wick-tube, plate B upon one side of the wick-tube and the part 0 upon the opposite side of the wick-tube, hinged to the said plate B, the said plate and hinged part 0 adapted to be moved up and down upon said wick-tube, the wick'tube constructed with an outward projection,f, toward the said hinged part 0, and the said hinged part 0 constructed with a corresponding inward projection, e, the said projections e f being adapted to engage each other as the extinguisher approaches its extreme up position, substantially as described.

4. The combination of the wick-tube, the plate B on one side of the said wick-tube, and the part 0 upon the opposite side of the wicktube, hinged to said plate B, the said plate and hinged part 0 being adapted to be moved up and down upon the wick tube as a guide, a lever hung in the burner, one arm extending into engagement with the said plate B, the other extending outward as a handle, the wicktube and the said part 0 constructed with corresponding projections on their adjacent faces adapted to engage each other as the extinguisher approaches its extreme up position, substantially as described.
