My invention relates to incinerating means as hereinafter set forth.

Among the objects of my invention are to provide means for superheating air so that foreign bodies are incinerated and destroyed; to supply air free from bacterial and injurious foreign bodies; to provide sterile air or gas for commercial or hospital use; to create means for superheating air which can be attached to other apparatus where 'pure air free from impurities and foreign bcdies is needed and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

Figs. l, 2 and 3 are front `elevations of embodiments of my invention; Fig. 4 is a detail of the adjusting means.

One embodiment selected to illustrate my invention comprises an inner tube I and an outer tube il. Said inner tube Ii) is constructed of heat conducting material and is connected by suitable means, such as wires, to an electric or other heat producing supply. The inner tube IB has an open air receiving end I2 and an opposite closed end I3. Adjacent the closed end I3 is a circumferential outlet It leading to an annular space I5 between the inner and outer tubes Il) and i i. Both ends i@ and Il of the outer tube I I are closed to the atmosphere. Adjacent one end of the cuter tube II, preferably farthest from the circumferential outlet lll is an exit tube I8 leading from the annular space I5. The exit tube i8 may be connected with other apparatus to receive the superheated air.

As a variation the inner tube Il! may not in itself be a heating element but may be surrounded by a heating coil I9 the ends of which heating coil it are connected to a proper electric or other heat producing supply.

In operation air, or gas, enters the open end I2 of the inner tube IE! and passes through the inner tube toward the opposite end where it passes out through circumferential outlet M and reverses itself to flow in the annular space I5 between the inner and outer tubes I0 and II where it comes in direct contact with the outside of the heating element. The air then passes through the exit tube lil for use or storage.

Another embodiment shown in Fig, 3 discloses a central solid heating element 20 surrounded by a spaced outer tube 2l and connected by suitable means to an electric or other heat producing supply. Both ends 22 and E3 of said outer tube il are open and receive air from the atmosphere which passes directly along side the heating ele- (Cl. 21B-39) ment 2B where it is heated. Adjacent the central portion of outertube 2l and connecting therewith is an exit tube 24 out of which the superheated air passes for use or storage. I may provide that either of said

open ends

22 or 23 may be closed. 5

My structure is held in position by supports to a base 26. Adjacent either side of outer tube 2! are engaging members 2l through the bottom of which passes a bolt 2i! connected by screw threaded shank 229 to a thumb nut 39. By operation of the thumb nut 39 the position of the outer tube 2l may be raised so as to narrow the space on one side I5 between the outer tube 2l and the heating element Ztl. This narrower annular space l5 will cause the air to pass closer to the heating element fit `and insure the incineration of foreign bodies.

By thus narrowing the annular passage I5 on one side through making the heating element eccentric to the outer tube 2l, the heat is kept more intense in said narrow passage. This will cause foreign bodies to come into direct contact with the heating element and be incinerated. Any remains from the incineration of said foreign bodies will be deposited on said heating element and will not pass out of my heating structure.

While I have shown my structure with fairly straight lines I wish it understood that my heating member on the outer tube or both may be designed to have curves or corners for the reception of foreign bodies without `departing from the spirit of my invention.

An efficient result is obtained when the heating element has reached a cherry red or incandescent heat. After the air has passed the heating element in such a condition it has been heated and reheated to such a temperature that all bacteria have been exterminated. Likewise all foreign bodies have been cremated. The air, or its equivaient such as gas, will then pass out the exit tube sterile and free of foreign bodies.

My heating element is removable from the outer tube so that it may be cleaned and the remains of foreign bodies deposited thereon in operation, removed.

While I have shown herein preferred embodiments of my invention yet I wish it understood that the same are susceptible of modification and change without departing from the spirit of my 50 invention.

Having thus described my invention, I claim:

l. Incinerating means comprising a heating member, a spaced tube surrounding said heating member, means for moving said tube closer 55 to said heating member so as to narrow a space between them, and an exit tube.

2.1ncinerating means comprising a heating member, a spaced tube surrounding said heating member, said tube having an air receiving inlet leading to the space between the tube and the heating member, means for moving said tube closer to said heating member so as to form a more narrow passage between them and give more heat to the air passing through said passage and incinerate foreign bodies in said air, and an exit tube.

3. An hygienic incinerator for supplying air free from foreign bodies comprising a pair of spaced hollow tubes, one within the other, the inner of said tubes being heated to an incandescent heat, said inner tube having an air receiving end and a closed end with an opening adjacent thereto, so that air passing through is first superheated by direct contact with the incandescent inner walls of said inner tube, and as said air passes through the opening and reverses itself in the space between the tubes it is again superheated by direct contact with the incandescent outer walls of said inner tube, so as to doubly provide for incineration of foreign bodies in said air, and an exit member.

4. An hygienic incinerator for supplying air free from foreign bodies comprising a hollow inner tube having an open end leading from the atmosphere, a hollow outer tube surrounding a substantial portion of said hollow inner tube and spaced to leave a passage between said tubes, said inner tube being highly heated so that its inner and outer walls are incandescent, said inner tube having a closed end and an opening adjacent said closed end, so that air which has come into the open end passes forwardly and directly against the incandescent inside walls of said inner tube, thence out through said opening and backwardly into the passage between said tubes and against the incandescent outer walls of the inner tube and into an exit member.

5. An hygienic incinerator for supplying air free from foreign bodies comprising a central solid member, a hollow outer tube having inlets leading from the atmosphere, said tube surrounding said solid member and spaced to leave a passage between said solid member and said tube, said solid member being heated to incandescence so that air which has come into the inlets passes directly against the incandescent solid member, and an exit tube leading Afrom substantially the center oi the tube.

6. Incinerating means comprising a hollow heating member, a spaced tube surrounding said heating member, means for moving said tube closer to said heating member so as to narrow a space between them, and an exit tube.

Incinerating means comprising a hollow heating member. a spaced tube surrounding said heating member, said tube having an air receiving inlet leading to the space between the tube and the heating member, means for moving said tube closer to said heating member so as to form a more narrow passage between them and give more heat to the air passing through said passage and incinerate foreign bodies in said air, and an exit tube.

8. Incinerating means comprising a solid heating member, a spaced tube surrounding said heating member7 means for moving said tube closer to said heating member so as to narrow a space between them, and an exit tube.

9. Incinerating means comprising a solid heating member, a spaced tube surrounding said heating member, said tube having an air receiving inlet leading to the space between the tube and the heating member, means for moving said tube closer to said heating member so as to form a .more narrow passage between them and give more heat to the air passing through said passage and incinerate foreign bodies in said air, and an exit tube.
