LIGHTING DEVICE.

Specification of Letters Patent.

Patented Aug. A22, 1905.

Application filed March 8, 1905. Serial No. 249,081;

T0 all whom it may con/cern:

Be it known that I, THOMAS S. SAYRE, a citizen of the United States, and a resident of Cape May, New Jersey, have invented certain Improvements in Lighting Devices, of which the following is a specification.

` My invention relates to that class of lighting devices in which are employed a lamp having' a wick which is ignited by an electric spark, the object of my invention being to so construct such a lighting device as to insure the ignition of the wick on each operation of the device. rThis object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a vertical sectional view of a lighting apparatus constructed in accordance with my invention and showing the parts in the inoperative position-that is to say, with the wick unlighted; and Fig. 2 is a view, partly in section and partly in side elevation, showing the parts in the operative positionthat is to say, with the wick lighted.

1 represents a casing containing in its lower portion an electric-battery cell 2 and induction-coil 2L and in the upper portion a reservoir 3 for alcohol, gasolene, or other inflammable liquid, said upper portion of the casing being also provided with a central tube 4, perforated asto its lower portion, so that the infiammable fluid can gain access to the interior of the same, the tube also serving as a filling-tube for the lamp. Centrally within the tube-4 is a smaller tube 5, containing a mass of insulating material through which extends a rod 6, which is connected at its lower end to one of the poles of the electric generator, whose other pole is connected to the casing 1. The upper end of the rod 6 projects above the tube 5 and is surrounded by a wick 7, which also surrounds the tube 5 andV extends down into the iniiammable liquid in the reservoir 3, the top of the rod 6 projecting slightly above the top of the wick, as shown in Eig. 1.

Fitted so as to slide freely within the tube 4 is a tubular plunger 9, mounted upon a coiled spring 10, which is disposed in the lower portion of the tube 4, said plunger 9 having a projecting handle 11,whereby it can be readily depressed. The top of the plunger 9 is normally closed by a cap or cover 12, which is pivoted to one side of the plunger at 13 and is acted upon by a rod 14 and aspring 15. The rod 14 is guided in an opening in the upper portion of the plunger and extends down on the inside of said plunger to the bottom of the tube 4, the length of said rod 14 being such that as the plunger is depressed the upper end of the rod 14 will contact with the under side of the cap or cover 12 at a point somewhat in advance of the pivot of the same just after the upper end of the rod 6 has come into contact with the terminal which is carried by the cap. This terminal consists of a pivoted trigger 16, normally retained in the position shown in Fig. 1 by the action of a spring 17, which is secured to the top of the cap and acts upon a projecting heel 18 on the trigger. The said trigger has a beveled lower end for being acted upon by the projecting upper end of the rod 6.

When the parts are in their normal position, (shown in Fig. 1,) the plunger 9 is raised, so that its upper end is some distance above the top of the wick and also above the projecting tip of the rod 6, the terminal 16 being free from contact with the latter. By pressing down upon the handle 11 of the plunger, however, the beveled end of the trigger 16 is first caused to contact with the projecting tip of the rod 6, which laterally deflects the trigger, the sliding of one upon the other insuring good electrical contact. As

the downward movement of the plunger continues the upper end of the rod 14 strikes the under side of the cap 12 and causes a quick lifting of said cap, so as to free the trigger 16 from contact with the rod 6, thus producing a spark. The upward movement of the cap 12 continues until said cap finally strikes and deiiects the upper end of the spring 15, as shown in Fig. 2. When the plunger 9 is raised and its cap 12 is closed, as shown in Fig. l, more or less gas or vapor collects in the upper portion ofthe plunger, and when saiolplunger is forced downwardly this gas or vapor is discharged and is instantly ignited when the electric spark has been formed by the separation of the rod 6 and trigger 16, thus insuring the lighting of the wick by the time the plunger 9 is fully depressed, as shown in Fig. 2. When the plunger is again permitted to rise, the spring 15 presses inwardly upon the cap or cover 12 until the latter has passed beyond the vertical line, after which it falls by its own weight and the iiame of the wick is extinguished. The same results will be obtained if the plunger 9 is stationary and the lamp structure is moved.

Hence it is immaterial to the main purpose of my invention which of the parts actually has power applied to it to move it so long as there is movement of the one relatively to the other. The rod 14 passes through a yoke 2O on the inner side of the plunger 9 and has above said yoke a projecting lug 21, so that when the plunger 9 is removed from the lamp it will carry the rod 14 with it, the yoke and lug being so located, however, that they will not interfere with the depression of the plunger independently of the rod. The construction shown, however, is preferred.

Having thus described my invention, l claim and desire to secure by Letters Patent-- l. A lighting device in which are employed an electric sparking device, and a lamp and plunger movable relatively to one another, said plunger extending beyond the wick of the lamp, whereby a volume of gas or vapor will be expelled and ignited when the spark is formed, substantially as specified. j

2. A lighting device in which are employed an electric sparking' device, and a lamp and plunger movable relatively to one another, said plunger carrying one of the terminals of the sparking device and extending beyond the wick of the lamp, whereby a volume of gas or vapor will be expelled and ignited when the spark is formed, substantially as speci lied.

3. The combination, in a lighting device, of an electric sparking device, a lamp having a wick and plunger having' a portion surrounding the wick and extending beyond the same, said lamp and plunger being movable relatively to one another, whereby a volume of gas or Vapor is expelled when such movement is effected, substantially as specified.

4. The combination, in a lighting device, of an electric sparking device, a lamp having a wick and a plunger surrounding said wick and carrying one of the terminals of said sparking device, said plunger extending' beyond the wick and said lamp and plunger being' movable relatively to one another, whereby a volume of gas or vapor is expelled -when such movement is permitted, substantially as specified.
