. TORCH AND.LAMP OPENER.

SPECIFICATION forming part of Letters Patent No. 288,439, dated November 13, 1883. Application filed August 18, 1883. (No model.)

To all whom. it may concern:

Be it known that I, ALEXANDER O. HUM- PHREYS, a resident of Bayonne city, inthe county of Hudson and State of New Jersey,

have invented an Improved Torch and Lamp Opener, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which Figure 1 represents a side view of my improved combined torch and lamp opener, showing it applied to a lamp. Fig. 2 is a face view of the same; Fig. 3, a top view of the same; Fig. 4, a vertical central section of the same;

2. Fig. 6 is an enlarged face view of the upper portion of the instrument;

The object of this invention is to provide for the lanterns that are known as Pintsch Lanterns, and for others of analogous construction, a tool by which such lanterns can be easily lighted. to are, for example, such as are shown in Letters Patent No. 268,373, of November 28,1882. In order to open such a lamp, it is necessary first to let down the glass bowl, then to open the gas-cock, and then to apply the flame to the burner. For the purpose of most conveniently performing these operations my improved instrument has been devised.

lamp, and held there when the lamp is oper-.

ative by a spring-catch, D. This spring-catch is in Fig. 1 shown pushed off the rim B, the latter being already partly moved away from the body 0.

E in Fig. 1 is the gas-pipe leading to the burner in the lamp. F is the cock by which said pipe is opened and closed.

The instrument which I have invented is,

Fig. 5, a vertical section on the line 0 c, Fig.

The lanterns of the kind referred The invention consists, principally, in con-.

a receptacle for the wick, or it may contain alcohol or other fluid, as may be desired.

From the upper part of the chamber H, preferably in straight line with the handle G, extends upward a stem, a, which at its upper end carries the forked instrument L. This forked instrument is composed of three prongs,

b, d, and e. The prongs b c by themselves form a U-shaped claw, as clearly shown in Figs. 2 and 6, and are the outer prongs of the forked instrument L. The central prong, (Z, is shorter than the others, and is turned or bent aside, as clearly shown in Figs. 4 and 5, having a rounded upper face. The prong e is provided with a cylindrical cavity, f, at its upper end, as shown in Figs. 3 and 5, and has an inwardly-projecting vertical spur, 9, that enters into said cavity, so that it will be a wrench for opening the cylindrical cock, F, the spur 9 being adapted to fit the groove or channel h in said cook, or if the cock should have a projecting spur the cavity of the prong 6 would be provided with a corresponding groove. The upper end of this cavity is flaredthat is to say, the continuous edge is beveled in 8 5 the manner shown inlFig. 5-so that the keye can be applied to the cylindrical cock F to an extent to grasp said cock before the spur g finds its position in the groove h. In other words,

I have found that hollow keys, otherwise 0 adapted to fit such cocks, are inconvenient to use, because they cannot be applied to the cock and turned on it before the spur finds the groove, but must be aligned with precision before application, in order to permit of 5 the proper engagement of the parts, and I find that by flaring the opening in the key 6, but keeping the spur 9 below this flaring portion, I am enabled to connect the key to the cock sufficiently to allow the key to be turned on the cook until the engagement referred to takes place.

From the foregoing description it will be readily understood how the instrument is used to open and close the cock F. It remains to state how it is used to open the lamp. Fig. 1 shows best how this done, namely: the instrument is placed with the bent prong d turned toward the glass bowl A, against the side of the lamp-body C, so as to straddle the springcatch Dthat is to say, so that the springeateh will be between the two prongs I) and 0. At the same time the end of the bent prong (I will be under the rim B and between the catch D and the-bowl A. The attendant, holding the instrument in that position, now swings it in the direction of the arrow,which is shown in Fig. 1, with the point of contact 1' between the prongs b c and the body 0 as fulcrum, thereby crowding the toe d against the springcatch D, and pushing the latter 01f the rim B.

Nevertheless the toe d is not withdrawn from under the rim B, and the attendant, as soon as he finds that the catch D has been disengaged, lowers his instrument, which now sustains the hinged bowl A by its rim, and lets said bowl gently down, whereas,without having the means described for sustaining the bowl, the latter would be liable to drop violently on its hinge and break or injure the same. The torch I J can now be applied to the burner, and then the bowl pushed back to its proper place.

I claim- 1. The lamp-opening tool L, composed of parallel prongs b e and intermediate prong, d, the prong (I being bent aside and shorter than the other prongs, substantially as described.

2. The cock-opening key e, made with the internal vertical spur, g, cylindrical cavity f, and beveled continuous upper edge above the spur 9, all arranged to fita cylindrical cock, substantially as described.

3. The combination, in the tool L, of the parallel prongs b e and the central bent prong, cl, with each other, the prong 6 being hollow and provided with the spur g, to also constitute a cock-opener, substantially as specified.

4. The combination of the handle G, chamber H, wicktube J, and stem at with the three-pronged tool L, which has its central prong bent out and arranged for operation substantially as herein shown and described.
