IVILLIAM HENRY MURRAY, OF IVANDSIVORTII, ENGLAND.

VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 453,818, dated June 9, 1891. Application filed November 4, 1890. Serial No. 370.357. (N0 model.) Patented in England November 30,1889, No. 19,262.

To all whom it may concern:

Be it known that I, \VILLIAM HENRY MUR- RAY,chemists assistant, of 15 Mayfield Villas, Merton Road, \Vandsworth, in the county of Surrey, England, a subject of the Queen of Great Britain, have invented an Improved Apparatus for vaporizing Medicines, Disinfectants, Perfumes, and other Substances, (for which I have made application for Letters Patent in Great Britain, No. 19,262, dated No vember 30, 1880,) of which the following is a specification.

This invention consists of an apparatus or contrivance for vaporizing by heat-such as from the flame of a gas or other suitable burner or lamp, for instance, aspirit-lamp any suitable medicines, chemicals, or chemical compounds for medicinal purposes or 0th- Wise, such as disinfectants and perfumes, &c., or for vaporizing or burning any other substances or materials, as desired-for instance, insect-destroyers, microbe-killers, &c.-and for which it may be suitable.

The chemicals oringredicnts are contained in a kind of flask or holder of any suitable material, (but advantageously made of glass,) and this holder or vessel is placed in the center part of the apparatus or contrivance which forms the subject-matter of the present invention, and which I will now proceed toifully describe with reference to the accompanying sheets of drawings, so that the said invention may be fully understood and readily carried into practice.

Figure I represents a side view in elevation of the said apparatus or contrivance and heated by a gas-jet on the well-known Bunsen burner principle. Fig. II is a vertical central section of Fig. I. Fig. III is a plan of Fig. I with the double shield or cover removed. Fig. IV is a similar apparatus only heated by a spirit-lamp instead of by a gasjet, as in Figs. I to III.

a is the bottom or supporting framemountcd on legs a and carrying the gas-pipe b, the turned-up end Z) of which forms the burner. Upon this frame a is placed the flask c or other convenient vessel which contains the chemicals oringredients to be vaporized, and over this flash 0 is placed the double casing (Z and c, the inner part (Z of which completely covers the flask or vessel 0 and forming an annular space no between said inner case ('1 and the outer wall .0 and top 6. The burner or heat-producer is mounted in this annular space a", between the inner casing (Z and the outer casing c, and air to support combustion is admitted through suitable openings below, while the products of combustion can escape through suitable openings f andf in the easing or outer wall 6, these holes f and f being of such a size that a warm body of air is retained in the space ,r. The flame from the burner thus produces a constant heat (subj ect to regulation) around the flask or chemical-holder c, and so vaporizes the contents which pass out up the passage or chimney (1 into the room or compartment in which the apparatus is in use.

Fig. IV shows an equivalent apparatus, only the heat-producer in this case is a spiritlamp, the reservoir or vessel 9 for holding the spirits forming the base or stand upon which legs a of the apparatus are mounted.

All the other parts are identical or equivalent to those previously described.

It will be obvious that the apparatus may be made of any size and proportions or di mensions, according to requirements, and

any suitable material or materials may be used in the construction thereof, though it may be mentioned that brass or copper will be found very advantageous for forming the parts (Z d and c e, which. latter maybe formed all in one part, as shown, or in separate parts, if desired.

The form or shape of the apparatus maybe varied, if desired,

The arrangement of the shield or wall (1 between the burner or heat-producer and the vessel 0, containing the chemicals, dsc, is of great importance and forms an essential feature of my present invention.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- I. In a vaporizer, the combination, with an exterior casing closed at the top, of an interior casing in said. exterior casing, a burner at the side of the interior casing and in the space porized in said interior casing, and a burner between said interior and exterior casings, between said interior and exterior casings, and a vessel in said interior casing for receivsubstantially as set forth.
