LAMP-EXTINGUISHER AND WlCK-TRIMMER COMBINED.

SPEGIFIUATION forming part of Letters Patent No. 281,232, dated July 17, 1883. Application filed April 30, 1883. (No model.)

To all whom it may concern:

Be it known that we, ALBERT BEcHrEL,

. guishing a lamp and for trimming the wick thereof, the following is a full detailed description of the construction and operation of the same, reference being had to the accompanying drawings for illustration, and making a part of this specification, in which Figure 1 of the drawings represents a side view of a lamp-burner, a portion of which is broken away that the inside mechanism may be seen. Fig. 2 is a detached section of the burner, showing the internal mechanism in a different position than the same is shown in Fig. 1. Fig. 3 is a top view of the burner with the cap or dome removed.

Like letters of reference refer to like parts in the several views.

It is customary to extinguish a lamp by blowing down into the chimney. This practice, unless the wick is first turned low down, is attended with danger of explosion in consequence of the heated gas being suddenly arrested from being consumed or from escaping through the top of the chimney, its arrest and accumulation in the chimney, together with the air blown therein, which becomes immediately heated and expanded, cause the aforesaid explosiomwhich is wholly avoided by the invention herein described.

The invention also is adapted to remove from the wick the incrustation, which is usually done by first removing the chimney to obtain access to the wick, the incrusted carbon then being scraped off from the wick or re moved by means of a pair of shears. Removing the chimney for the abovespeoified purpose is avoided by the application to the lamp of the extinguishing and trimming device above mentioned.

As shown in the drawings, A represents the base of the burner, and by which it is screwed into the bowl of the lamp. Bis the shell above I the base, on which the chimney stand s, and held thereon by the springs O, in the ordinary way.

D is the perforated top or diaphragm of the shell. E is the wick -tube, andFthe shaft of the wick-rollers, all of which are or may be like those in ordinary lamp-burners.

{G and H are a pair of hangers depending from the perforated top D, the two ends of which are joined to each other bya cross-bar, I. In the end of the hanger H is pivoted a lever, J, the outer end of which is held in a guide, K. The inner end of the lever is turned upward, forming an arm, L, above the diaphragm.

To the extreme end of the arm is secured a jaw, M, Fig. 1, 2. top view of which is shown in Fig. 3. Said jaw consists of a steel plate having its two ends turned at right angles, as seen at a a. The upper edge of the plate is a sharp cutting-edge, for a purpose presently shown. The length of the jaw between the ends a a is a little longer than the width of the wick-tube, as seen in Fig. 3.

To the end of the hanger G is pivoted one 7 end of an arm, N. The end of said arm is bent at an angle corresponding to the arm L of the lever J, as seen in Figs. 1 and 2.

To the end of armh is secured a jaw,O. Said jaw is a duplicate of the jaw M, and forming therewith a pair of j aws,which,when brought together, as seen in Fig. 1, their lower edges inclose the-end of the wick-tube, whereas the upper edges of the jaw come together as two cutting-edges above the end of the wick-tube, so that the end of said tube is wholly inclosed by the two jaws whentogether, as shown in Fig. 1.

In. the lever J is a pin, 0, by which the arm N is operated by the arm J, and conjointly therewith, for actuating the jaws simultaneous- 1y, as and for a purpose presently shown.

P is a spring, one end of which is in (actual relation with the arm N, and whereby said arm is retained in contact with the pin 0 for being operated thereby. The opposite end of said 5 spring is adapted to engage the notch 61 in the elbow of the lever J, as will hereinafter be seen.

Practically the operation of the above-described device is as follows: Let it be supposed that a lamp having applied thereto the above 100 described device is lighted. During the burning period of thelamp the jaws M and O are distended from each other, as seen in Figs. 2 and 3, so that the wick-tube is free between them. This relation of the jaws to the wick-tube is maintained by the end 6 of the spring P being lodged in the notch d of the lever J, and by a slight pressure downward thereon the spring becomes disengaged from the notch. The opposite end of the spring, by its resiliency, forces upward the arm N,which in turn, by means of the pin 0, pushes also the lever J upward at the same instant, causing the two jaws to come together and inclose between them the end of the wick-tube, as seen in Fig. 1,which,as a consequence, smothers outthe flame. The jaws are removed from over the tube by pressing upward upon the lower end of the lever J, thereby, depressing the opposite end, causing the pin 0 to force down the arm N until the notch d engages the end of the spring, which, as before mentioned, retains the jaws open, as seen in Figs. 2 and 3. If the end of the wick is incrusted, it is removed by screwing up the wick far enough to be caught between the cutting-edges of the jaws when they shall come together. When this is done, the end of the lever J is pressed down upon, thereby causing the jaws to spring together and by their cutting-edges slip off the crust from the wick. It is preferred, however, to open the jaws and then screw the wick above them. The jaws are then closed again, gripping the wick just below the crust. Now, on screwing down the wick the edges of the jaws scrape off the crust, leaving the wick clean and trim for being lighted.

If while the lamp is burning it should be 1 tipped over, it would be at once extinguished by the jaws, which, by the concussion consequent upon the fall,would disengage the spring from the arm, so that the jaws would spring together and smother out the lamp, as above mentioned.

-What we claim as our invention, and desire to secure by Letters Patent, is-

1. In oil-lamps, the lever J ,having secured to the end thereof a jaw, N, and provided with a notch and pin, 0, arranged in relation to and in combination with the arm N, spring P, and jaw, and co-operating therewith in-the manner substantially as described, and for the purpose specified.

2. In combination with the arm N,with jaw O, and lever J, provided with a notch, 01, and j aw M, the spring P, for operating the arm N, provided with the end 6 for engaging the lever J in the manner substantially as described, and for the purpose set forth.

3. In oil-lamps, the lever J, provided with a notch, d, pin and jaw M, arm N, jaw O, and spring P, combined and arranged to operate and co-operate in relation to the wick-tube of the lamp substantially as described, and for the purposes specified.

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