Letters Patent No. 114,329, dated May 2, 1871 IMPROVEMENT-IN PROTECTORS FOR GAS OR VAPOR-BURNERS.

The Schedule referred to in these Letters Patent and niaking part of the same.

I, Burns Nur'rme, of Randolph,county of Orange and State of Vermont, have invented certain Improvements in Protectors for Lamp, Gas, or Vapor-Burners, of which the following is a specification.

The nature of my invention consists in the construction of a plate called a protector, for combination with lamp, gas, or vapor-burners, to prevent their flames from going out so easily when a current of air strikes them, as they are being carried about the house, in such a manner that it may be instantly so adjusted as to deflect the flames from a nearly horizontal to a nearly perpendicular or vertical direction, and flatten or spread them so as to absorb more oxygen from the air by the flames or jets striking the raised or elevated por tions of it, which thereby absorb more heat and conduct it to the burner-tip, which, by increased heat, converts the vapor within it into gas more rapidly, and produces a larger and more adhesivefiame, and also, by its uneven surface, inclining the jets to hug and impart their heat to some part of the protector when blown out of their position by the wind, as well as be shielded from the greatest force of the current; and also so that it can be instantly so adjusted that the flames will be emitted in their naturally horizontal direction if desired.

The drawing Number 1 is a transverse sectional view of a protector, in combination with one of my patent lamp gas-burners, as if cut in two from to in No. 3, and showing two flames deflected.

Number 2 is an elevation view, with the upper section of the wick-tube.

Number 3 is a vertical view showing the flame or central part A, deflectors O, and hole G, through which the burner-tip projects.

The central part of the protector A is plain, and about half an inch in diameter, and when in use rests upon the upper end of the socket in the wick-tube, which holds to the gasificator or burner-tip, as seen' at B, No. 1. (The protector is usually made of No. 28 sheet brass.)

The part 0 is inclined upward at an angle of about forty-five degrees with orfrom the plane A, in its central or highest part, and its sides curve downward, so as to form nearly a semicircle at its outward extremity, as seen at D, No. 2.

When it is desired to make the flames adhesive, or able to resist currents of air, the protector is turned so that the jets or flames issuing from the holes in the burner-tip shall strike the raised portions 0 aboui midway between the plane A and its outer extremity, and by so striking they are turned upward nearly perpendicularly, as represented at E, No. 1, and heat therefrom is absorbed by the raised parts C and conducted by the plane A to the chamber E, which converts the vapor therein more rapidly into gas, and con sequently produces a larger, more powerful, and tenacious flame, which, in conjunction with the other objects and effects of the protector, (which are to ward off or prevent currents of air from directly striking the jets at the point of emission from the chamber F, to deflect the flames upward, and also afford a condensing or heatin g plate of such form that thejets or flames will still bug or adhere to some part of it, although there may be quite stro'ngand even counter-currents of air striking against it,) removes the greatest objection now existing to the general use of these burners for domestic purposes, to wit, that they go out so easily.

When .it is desired that the jets shall assume their natural or nearly horizontal direction, 'the protector is turned laterally one-eighth of a circle, if the burner emits four jets only equidistant from each other, so that the jets pass between the raised portions of the protector and not against any part of it.

In case the burner emits more than four jets, the protector should have a corresponding number of the raised parts G.

The hole G is of such size as to go easily over the burner-tip and allow the protector to be readily turned to any desired position by the point of the finger-mail, pin, or knife.

While I have found by many and protracted exper iments that the form of the protector herein described is satisfactorily efiieacious to the end desired, I have the whole plate, (which neutralizes somewhat coun-.

ter-currents of air,) and the concentrating or heat-aecumulating power of the whole plate, and its ready adjustability for a domestic-carrying or a parlor-stand light, or pendent light for entries, door-ways, 850., where the frequent opening of doors creates a current of air.

When a perpendicular or vertical flame is required from the center of the burner-tip, as is the case for lantern use, instead of having the jet-holes in the sides of the tips, the hole or holes are made in the upper end of the tip, and the protector is made of such size, thickness, and form that the vertical jet or jets strike against some part of the protector, which part is elongated, raised, and bent over thejetfor the purpose, and for rceiving the heataud transmitting it to the vapor-chamber l and of flattening and widening the flame, while its natural tendency to a vertical position prevents it from being great-ly'deflected therefrom. v

I claim as my invention- The corrugated or uneven surface deflecting pro teetor, in combination with lamp, gas, or vapor-burners, substantially as described, and for the purposes herein set forth.
