SPECIFICATION forming part of Letters Patent No. 507,838, dated October 31, 1893.

Application tiled March 31, 1892. Serial No. 427,240. (No inodel.) Patented in England February 13, 1892, No. 2,842, and n f Canada September 3, 1892, No. 40,2]5.

To @ZZ whom it may concern:

Be it known that we, JOHN THOMSON PAUL and JAMES PAUL, lamp and lantern manufacturers, both of Grove Works, Brandtield Street, Fountainbridge, Edinburgh, in the county of Mid-Lothian, Scotland, have invented Improvements in Lanterns, (for which we have obtained Letters Patent in Great Britain, No. 2,842, dated February 13, 1892, and in Canada, No. 40,215, dated September 3, 1892,) of which the following is a specification.

This invention relates to improvements in 1s tltiirm or other lanterns, lamps, stoves and the The invention is more particularly applicable to storm lanterns, and has for its object to obtain a very steady flame under all conditions of wind and to obtain other` advantages.

In the accompanying drawings, Figure 1 is an elevation of a storm lantern constructed in accordance with our invention. Fig. 2 is a part sectional elevation of the same, and Fig. .1s a plan of the lower part of the lantern. Flgs. 4 to 6 inclusive are details of our said lnvention.

The lantern consists of a carrying handle A, cowl B, cone O, oil fount D, and burner E, glass chimney X and glass globe Y protected by a Wire guard, as shown.

. The necessary air for combustion finds its way to the burner through the perforations e in the casing e. Inside'the said casing is a wind guard c2, shown more particularly in Fig. 2. This iigureshows the top of the burner lifted up by levers in accordance with a part of our invention hereinafter referred to.

The air ascends from under the lower edge of the said guard, as shown by the arrow in Fig. 2, fills the space below and around the -burner and passes through` the perforated ventilator plate or globe holder es, as in'dicated by the arrow, Fig. 2, the said plate e3 being shut down upon the top of the casing e when the lamp is in use as shown in Fig. 1. The air ascends through a portion only of the said ventilator plate e3, that is to say, it passes throughthe holes at the outer edge of the plate, fills the space between the chimney and the globe, gets heated there and then descends through the same plate by means of the inner holes of the plate into the chamber e4 formed below the Ventilator plate, the air finally escaping through the perforations e5 of the burner, as indicated by the arrow, up to and around the flame which burns through the ordinary dome e6 of the burner. By this arrangement of supplying air steadiness of the flame is insured as any gusts of air, when the lamp is used for outside purposes for example, are completely broken by the aforesaid system of leading the air and a steady flow of air heated by the chimney being supplied below the burner.

The arrangement for raising the ventilator plateor globe holder e3, as shown more particularly in Figs. 2 and 3, consists of levers F operated by the handle f as hereinafter more particularly described. The top of the lamp when thus raised and lowered from and to the lower part of the lantern is guided by the rods or uprights G, the said rods being the means by which the cone C with its cowl and handle is supported from the lower part of the lantern. By raising the ventilator plate or globe holder, as shown more particularly in Fig. 2, the wick can be quickly and easily lighted and extinguished and trimmed or the burner cleaned and there is entire safety from explosions when extinguishing the flame. There is also no liability of the lantern to upset when being lighted or extinguished.

The top of the globe may be provided with a tippet H so as to retain the heat between the chimney and the globe.

The globe is protected from breakage by the wire guard which forms another part of our said invention. The said guard is constructed of an arrangement of bent wire as shown in Fig. 1 and is such that it can be sprung or expanded over the globe and taken off in a similar manner, the said guard being thus self adjusting and can be readily put on or taken off. The guard may be constructed as shown in the drawings, of a hoop or wire K, which is jointed at 7o, surrounding the circumference of the globe and the legs lo which clasp the side of the globe may also be formed of one length of twisted wire, k2 being the joint of the wire. We do not limit ourselves to the said precise mode of constructing `the globe protector as there are variousiotherobvious ways of twisting or bending the wires to produce the same result, that is to say, a

IOO

wire protector that is self adjusting upon the globe and does not require support or attachment to any part of the lantern.

It will be seen that in accordance with our said invention when the lantern has to be lighted all that has to be done is to operate the levers when the ventilator plate carrying with it the burner cap, the chimney and the globe is raised up clear from the Wick, and thus allows the Wick to be got at without the slightest trouble.

As shown in Figs. 2 and 3, the appliance for elevating the ventilator plate e3 consists of the levers F operated by the handlef. The ventilator plate is provided with two opposite pins f against which the levers bear. Owing to the formation of the arms of the levers and the position of the pins, the ventilator plate is always elevated vertically as the arms are always bearing at the same vertical line so that there is no liability of the ventilator plate to be tilted from its vertical travel. The ends of the levers are provided with catches f2 which act as checks against the pins f and satisfactorily hold the ventilator plate in its elevated position it being readily perceived that when the pins f are in the catch portions f2 of the levers, the ventilator plate is fully open. In the plan Fig. 3 the ventilator plate is not shown and consequently the pins f are not shown. Also in thisigure the levers F are shown down.

A further part of our said invention relates to an improved feeder cap for the oil fount. As shown open in Fig. 4:, closed in Fig. 5, and in section Fig. 6, the cap is made to fit over the neck of the tank aperture without the necessity of any screw, and we employ a peculiar kind of bayonet joint consisting of a pin or projection j, which takes into the curved recess Z, formed in the side ofthe cap. The same formation being at opposite sides of the cap as shown in Fig. 6, all that is necessary to do is to press on the feeder cap and at the same time give it a turn when the mouth of the recess will take on to the projection j, and by continuing to turn the cap it will be forced down tight over the mouth of the feeder, owing to the sloping or curved formation of the `recess Z, until the projection j is locked at the end of the recess owing to the particular formation of the end of the recess, the piece of cork or other material with which the under side of the top of the cap is lined, assisting in keeping the cap tight and locked.

The hereinbefore described various arrangements of our said invention may be altered in many ways without departing from theessential featuresof our said invention.

Our said improvements are applicable to all kinds of lanterns, lamps, or stoves, and they are also in part applicable to either oil or gas; the wire protector for example is equally applicable for any globe whether surrounding an oil or gas flame or other light.
