Letters Patent No. 91,195, dated June 8, 1869.

IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and making pelt of the same To all whom it may concern Be it known that 1, Cinemas ZAISER, of Newark, in the county of Essex, and State of New Jersey, have invented a new and useful Improvement in Lamps; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawing, forming part of this specification, in which drawing- Figure 1 represents a vertical central section of this invention.

Figure 2 is a horizontal section thereof.

Similar letters indicate corresponding parts.

This invention consists in an arrangement of an envelope or jacket, struck up or otherwise produced, ofsheet-metal, and-made in two halves, connected to each other, or to a lamp, bya suitable joint, and surrounding the oil-cistern of the lamp, the space between or oil-lamp, said cistern being made of glass or other transparent material, in any desired form or shape, and being supported by the standard or column B, in the usual manner. f I

, With ordinary lamps of this kind it happens frequently that the .oil contained in the cistern explodes, and in most cases such explosions are the cause of fatal results.

In many cases such fatal results are also produced if the lamp, while lighted, is accidentally upset, because'in such a casethe oil flows out, catches fire, and spreads rapidly over a large area. I

All these dangers are avoided by protecting the oilcistern A by means of an envelope or jacket, 0, which 1 construct, by preference, of sheet-metal, in two halves, one half 'bein g firmly secured to the standard B below, and to the neck of the oil-cistern above, whilethe other half is connected to the first by a hinge-joint, a, so that it can be readily opened or closed; or, if desired, one or both halves may be connected to the column or standard B, by hinge-joints, so that the same can be opened and closed at pleasure.

When closed, the two halves are fastened by a pin or any suitable catch.

The space between the envelope 0 and the oil-cistern is filled with loose cotton, or some other absorbent and fibrous material, which may be put in loosely, or whichmay be protected by wire gauze.

The object of the cotton or other absorbent material is twofold: first, it serves to absorb all the oil which runs down on the outside of the oil-cistern, ,so that the external surface of the envelope remains always clean and uusoiled; second, it the lamp explodes or is upset, the oil thrown out oi'the oil-cistern is absorbed by the cotton or other material, and fatal accidents are avoided.

The envelope also protects the oil-cistern from getting broken, and if the lamp is who filled, the envelope can be opened without difficulty, so that the level of the chin the cistern can be observed.

If desired, my envelope can be ornamented, so that it will improve the appearance of the lamp.

I do not claim broadly either an outer shell, enclosing the oil-reservoir, or a filling of cotton or similar materiahas 1 am aware that such have been used. Neither 'do I claim broadly an outer shell surrounding the oil-chamber, the space between the two being filled with absorbent material; but having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-- The outer shell-when so constructed as to enclose the entire oil chamber, the space between the two being filled with absorbent material, and so made as to be partially opened when desired, substantially as herein described.

This specification signed by me, this 8th day of J anuary, 1869.

CHARLES ZAISER.
