To (all whom it may concern.-
Be it known that I, ORLANDO M. THowLEss, a subject of the Queen of Great Britain, residingatNewark,in the countyofEsseX andState of New Jersey, have invented new and useful Improvements in Methods of Reinforcing Incandescent Gas-Mantles, of which the following is a specification.
My invention relates to incandescent mantles and to methods of improving the same.
The object of my invention is to produce a mantle giving more efficiency than those at present in use, which is stronger, and which can be transported without liability to breakage before use.
To carry out myinvention, I take the ordinary mantle,of which the WVelsbach may serve as a type, directly it is shaped and immerse it in a solution of collodion or melted paraflin or light-bodied lacquer or similar substances which have mixed with and suspended in them particles of the material of which the light-giving surface of the mantle is composed. The mantle is then removed from the oxid-carrying substance and dried while suspended with the broad portion downward. The carrying substance is best made of a good siccative material. The immersion of the mantle in the carrying substance leaves it impregnated with the collodion, parafiin, &c. containing the light-producing oxid which reinforces the mantle. There is a tendency for the particles to deposit on the high points of the mesh, as well as in the interstices, the particles thus deposited catching the heat, and consequently giving more light. This reinforcement also renders the mantle yielding and pliable, and consequently suitable for transportation without breakage. When the mantle is placed on the burner and lighted, the collodion or other carrying substance will burn away, leaving behind the reinforcing material and becoming closely associated therewith. This will make a more stable and better illuminating-mantle. Clippings from mantles, imperfect mantles, and old broken mantles may be used as a source of the reinforcing oxid material. Another advantage of mymechanically-suspended mixture of the combustible liquid and the oxids in the methods of forming a reinforced mantle consists in the fact that in drying the suspended mantle the combined material has a tendency to thicken somewhat at the lower portion of the mantle. The mantle receives the greatest heat near its lower extremity up to the point of the apex of the flame, owing to the fact that it is only between these points that the flame comes in actual contact with the mantle. From the apex of the flame to the top there is no contact with the flame, and the upper part of the mantle is heated only by radiation. Therefore the flame only being in direct contact with the lower part of the mantle a larger quantity of the light-giving material is most desirable in that portion of the mantle, and as the heat radiation is greater near the apex of the flame and gradually decreases therefrom toward the upper part of themantle it is of great value to have a gradually-decreasing amount of the light-giving reinforcing material the farther it is removed from the apex of the flame, which is brought about by my improved method of reinforcing mantles. The resulting mantle will have a light-giving portion gradually increasing in amount from the top downward and being greatest at the bottom.
I do not in this application claim the reinforced mantle manufactured according to my improved methods, having already filed a separate application for the same, Serial N 0. 721,792, June 24, 1899, of which this is a division.
Having thus described my invention, what I claim is- 1. The method of reinforcing incandescent mantles, which consists in impregnating a readily-combustible liquid capable of quickly becoming solid, with particles of light-giving material of the same nature as that forming the mantle, and immersing the mantle in said liquid.
2. The method of reinforcing incandescent mantles which consists in the following steps: first, impregnating a liquid, which when dry is combustible, with the oxids of thorium and similar metals; second, immersing the mantle in said liquid; third, drying the mantle; fourth, burning off the oxid-carrying substance, substantially as described.
3. The method of reinforcing incandescent mantles, which consists in immersing the ing, and thereby depositing on the mantle aii mantle in "a combustible liquid, holding in auxiliary covering increasing in thickness '16 mechanical combination oxids of the same from the top downward, substantially as denature as those forming the light-giving surscribed.
