To all whom it'may concern:

Be it known that I, JAMES OALZKINS",.Of the city of Hudson, in the county of Columbia and State of New York, have invented a new and improved mode of elevating and sustaining the temperature of gases and vapors evolved from volatile fluids or chemical compounds of any kind when employed for the production of light or heat; and I do hereby declare that the following is a full and exact description thereof, reference being had to t the accompanying drawings and to the letters of reference marked thereon.

Figure 1, is a perspective view ofan apparatus for heating the air, having one side removed. Fig. 2, is also a perspective view of a similar apparatus for the same purpose, one side removed. Fig. 3, is still another apparatus for the same purpose.

Letters A A A A, in Figs. 1 and 2, are chambers for heating the air. Letters B B I represent the metallic fire-box through which the heat is imparted to the air in the surrounding chambers. Letters a a a &c. are apertures for the air to pass from one chamber to another. Letters 6 b is a vertical partition in apparatus Fig. 1. Letters 0 0 indicate the space beneath this partition. Letters cl d d, &c., are horizontal partitions Figs. 1 and 2. Letters e e the eduction pipe leading the heated air into the generator or vessel containing the fluid or compound. Letters p p the induction pipe leading the air from the bellows or airchamber of the blower into the heating apparatus herein described. I

The nature of my invention consists in providing the induction pipe or conduit through which the air is forced into the generator or vessel containing the volatile fluid or compound (wide hydrocarbonblowers) with chambers, pipes or flues at anypoint between the bellows or air chamber and the fluid or compound contained in the generator, so that by applying heat to such chambers, pipes or flues, the air within becomes heated in itspassage to and before it enters the generator, or before it combines with the gas within, and thereby on coming in contact with it and with the fluid or compound from which it is evolved, elevates its temperature, increases its volatility and prevents condensation.

To enable others skilled in the art to make and use my invention I will proceed to these important. objects. i

describe some of the modes intwhichtII I pose to heat theair landtherebyto efiectl may be described as follows: I construct a metallic chamber of any convenient form,

into which, at the top, the. air is forced from the bellows orair-chan1ber.

across it and half or three fourths of an inch below the top is a horizontal partition l g (Z, (Z. Through this, directlyover the. fire- 1 box B, is an aperture of: the same size as the l 1 air pipe 0,, through which aperture the air i passes into the chamberA, .where itis.

Extending i I heated by coming in contactwith the firebox B. From this. chamberit passes be neath the vertical artition b, b, througha 1 space of about hal an inch in width, indi-: I cated by letters 0, c, and thence. into. the.

pipe, e, and the generator or vessel containmg the volatile fluid .or compound. [The fire boxB is a cylindrical pipe or chamber, closed at top and open at the bottom to K H:

admit the flame of a spirit lamp or any other heating process, whereby the air com ing in contact with this pipe or chamberB, 1 I

is heated before it passesoveror combines with the fluid or compound aforesaid.

Fig. 2 represents another mode and may.

be described as follows: A square, circular,

or other convenient shapedfimetallic chamher, having three or more horlzontalpars titions, forming between them distinct chambers or apartments A A A A, each opening into or communicating with the.

other at: alternate and opposite sides or corners through the apertures a, a, a, the 1 firebox B extending throughthe center of: I i

all from the bottom to the upper partition. The air is introduced through the pipe p, at the top, of ordinary temperature, and disc charged through cat the bottom, heated,

and thence into the generator elevating the temperature of the: gas within toany degree required.

Fig. 3 represents still another devicefor efleoting the same objectgwhichmay .bedee scribed thus: I coil the air pipe 9, into aconical form and then inclose it .ina conical metallic case a little larger than the cone of l pipe, having an aperture at the bottom to admit the heatingflameg The air in passing through the coil becomes. heated the same as in the chambers before described and represented in Figs. 1 and 2. The air may be admitted eitherat the .bottom,qtop

or sides of these chambers, so that the current shall pass upward downward or horizontally through them; but in all cases the point of discharge should be as near to the generator as possible, so that none of its heat shall be lost before reaching the fluid or compound within.

It is not any particular form of apparatus or mode of heating the air that I would claim, for it can be done in a great variety of Ways in addition to those I have described, and all equally effectual; but

What I claim as my invention, and desire JAMES CALKINS.
