JAMES C. WVEAVER, OF LURAY, VIRGINIA, (ADMINISTRATOR OF .I. M. AMISS, DEOEASED,) ASSIGNOR TO JAMES J SI-IEEHY, OF WASHINGTON, DISTRICT OF COLUMBIA.

LAM P-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 431,423, dated July 1, 1890. Application filed August 28, 1889. Serial No. 322,239. (No model.)

State of Virginia, did invent certain new and useful Improvements in Lamp-Extinguishers and I, JAMES C. WEAVER, administrator of the estate of the said JOSEPH M. AMIss, do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to lamp-extinguishers; and it has for its main object to produce at a minimum expense an extinguishing device which may be applied to burners such as are at present .in use and operated without any additional expense or mechanism and without any care or experience on the part of the attendant, the wick-movingwheel being all that is necessary to manipulate the device.

The invention will be fully understood from the following description and claims when taken in connection with the annexed drawings, in which- Figure 1 is a perspective view of a lampburner with the improvements applied, showing the hinged or pivoted plate closed upon the wick-tube. Fig. 2 is a diametrical sectional View of the same. Fig. 3 is a perspective view of the improved extinguisher removed from the burner. Fig. 4 is a perspective view of the device in a modified form; and Figs. 5 and 6 are details of the extinguisher-plate. Fig. 7ris a side view of a modiiication of the bar F, and Fig. 8 is a perspective view of a modification of the hinged plate G.

The lamp-burner illustrated in the accompanying drawings forms no part of the invention, but is used simply for the purpose of better illustrating the improvements and the application of the same thereto.

In the said drawings,A indicates a burner, which may be of any ordinary or approved construction. This burner has the usual wicktube a, the gallery I), and the lower threaded portion 0. Suitably journaled within the burner is a shaft B, having at one end the usual milled head D, and fixed to this shaft is the usual wick-moving wheel E, which latter is designed to partly enter the wick-tube and engage the wick;

The extinguishing device comprises a bar or strip F and a plate G. This bar or strip is provided with a series of perforations d, which are designed to be engaged by the spurs or teeth of the wheel E, and the said strip is also provided with an elongated slot 6. The plate G, which is designed to cover the upper end of the wick-tube, is hinged or pivoted to the upper end of the bar or strip F. This plate G is hinged or pivoted to the bar or strip in such a manner that when the said bar-has been raised through the medium of the wick-moving wheel the plate will turn over upon the wick and extinguish the flame, while by simply turning the wick-moving wheel so as to raise the wick the plate will be drawn down so as uncover the tube and consequently the wick.

, As there are various means by which the plate maybe connected with the strip or bar, and also many forms of bars or strips that may be used, it is not intended to be confined to the particular forms illustrated in the accompanying drawings, as it is simply necessary that the bar or strip should be provided with means to engage with the spurs or teeth of wick-moving wheel, and that the hinged or pivoted plate may cover the upper end of the tube when the wick has been drawn down and uncover the same as the wick is carried up, both acting simultaneously or conjunctively, the slot in the bar or strip being designed to receive the spurs of the wheel when it is desired that the extinguisher should remain idle.

Fig. 3 of the drawings shows the strip F as having a number of perforations and an elongated slot 6 above the same and in line therewith, while in Fig. 4 is shown the elongated slot in the bar or strip below the perforations, as both forms are practical. The form shown in Fig. 3 is, however, preferable, as the bar or strip must be depressed and out of the Way when it is not desirable to use the extinguisher and at such times as trimming the wick or removing and replacing it.

In the construction shown in Fig. 4, when it is desirable to move the wick, remove it, or

insert a new one without at the same time moving the extinguishing device, the strip or bar must be raised, so as to bring the slot therein to receive the spurs of the wick-moving-wheel. It will'also be observed that while there is shown and described the elongated slot in line with the perforations, yet such is not necessary, as the purpose of the slot is simply to receive the spurs of a wick-moving wheel at a certain point, so as to allow the bar to remain idle. The lower end of this bar or strip is provided with a stop, which may be a pin, an integral lug, or other suitable means.

Fig. 3 of the drawings shows the preferred construction of the hinged orpivoted plate and the manner of connecting the same with the bar or strip, although it is not intended to be confined to the exact construction which will presently be described, as in some cases a common hinge or pivotal joint may be employed and the plate provided with-an arm or shoulder, whereby it may engage the wick-tube when raised to cover the same and engage the crown or diaphragm of the burner when withdrawn from the top of the tube. In the said figure is shown the plate G as provided with a connecting branch or arm f, having an oblique slot g, through which the pivotal pin or pintle h passes, and the said branch or arm extends in rear of the said hinge or pivotal point, as seen at 71. By the employment of this slot g and the extension 1' on the arm of the plate G, when the bar has been drawn down by the action of the wick-moving wheel, the said wheelwill be allowed to enter the elongated slot in the bar, the latter being accomplished by simply throwing the hinged plate back upon its pivot, thereby allowing the bar or strip to become slightly depressed, the extension t serving, when the plate is turned up,to hold the bar in position with respect to the teeth of the wheel so that when the latter has been moved to lower the wick the said bar will be raised and its plate made to cover the wick-tube.

In Fig. 4 of the drawings is shown the plate simply hinged to the upper end of the perforated bar and the bar slightly extended,

so as to prevent the said plate from turning back upon the pivot. In some cases, where the hinge-plate is provided with suitable stops, the stops on the perforated bar may be omitted, and it is also obvious that instead of having a perforated bar a rack-bar might be employed, in which latter case a sufficient portion of the bar should be left plain, so as to free its engagement with the wick-moving wheel or a slot formed therein for the movement of said wheel.

In applying the improvements to a burner suitable means should be provided for guiding the strip in its up and down movements, and these guides are preferably formed by slotting the diaphragm Z, as at l, and the threaded body portion, as at m, in which slots the said bar is placed. I

As before described, the strip or bar is designed to engage with the wick-movin g wheel. Consequently such wheel need not necessarily enter the wick-tube, as it may be fixed at any convenient point to the shaft B.

By reference to Fig. 8 of the drawings it will be seen that a flange is turned in opposite directions on one of the longitudinal edges of the plate G. The flange a is designed, when the plate has been turned over the wicktube, to engage one side thereof and serve as.

a stop and means of seating the said plate upon the tube,while the flange b is designed to strike the diaphragm when the platehas been drawn down, and serves to hold the same in proper position for working.

Having described the invention, what is claimed is 1. The combination, with a burner having guides, of the toothed wheel and a light-extinguisher constructed to engage with thewheel, and consisting of a perforated strip mounted in-said guides, having aslot in addition to the perforations and a pivoted plate at its upper end, substantially as specified.

2. The combination, with a lamp-burner having guides, of its wick-moving wheel and a light-extinguisher constructed to engage with the wheel, and consisting of a strip having perforations and also a slot, and carrying at its upper end a pivot-ed plate, substantially as specified.

3. The combination, with a lamp-burner having guides, of its wick-moving wheel and a light-extinguisher constructed to engage with the wheel, and consisting of a perforated strip moving in said guides and carrying at its upper end a pivoted plate, the plate having its connecting-arm extended beyond the pivotal point, and also provided with a slot, substantially as specified.

at. The combination, with a lamp-burner, of a light-extinguishing device comprising a bar and plate hinged to one end thereof, said bar being arranged in guides and on the outer side of and in engagement with the wick-moving wheel, so that when the wheel is turned to move the wick in one direction said wheel will move the extinguisher in an opposite direction.

5. The combination, with a lamp-burner, of a light-extinguisher composed of a 'bar or strip and a plate hinged to the upper end thereof, the bar having a plurality of perforations and also a longitudinal slot, and the attaching part of the hinged plate also having a slot, whereby the slot of the bar may be made to receive the wheel and the perforations also receive the teeth of the wheel, substantially as specified.

6. The combination, with the-bar or strip having perforations and also having a longitudinal slot, of a plate hinged to the upper end of the strip and having its connecting portion provided with a slot such as described, and also projected beyond the slotted portion to bear upon the dome or top plate of a burner, whereby the perforations and also the slot of the strip may be made to receive and also free themselves from a toothed wheel, sub: stantially as specified.
