- NEW MEANS AND SYSTEM OF HEATING.

Application filed February 14, 1918.

To all whom it may concern:

Be it known that I, AARON TERRY, a citizen of the United States of America residing in Springfield, in the county of Humpden and State of Massachusetts. have invented New Means and Systems of Heating,

of which the following is a specification, reference being had to the accompanying drawings and letters of reference marked thereon.

It is a well known fact that the heating systems now in use are not economical and that many experts claim that from 75 to 90 per cent. of the heat units are wasted and that as a general rule not exceeding 5 per cent. of the heat units are actually utilized for heating purposes.

In the systems now in use a large perccnb age of the heat units are lost because of the fact that the heat is largely taken up in heating the. conduits and heavy radiators and because of the fact that the heated gases escape through the chimney without first .giving up the heat carried by them.

The objects of my invention are to provide a means whereby a very much larger percentage of the heat units may be utilized for heating 'purposes than has heretofore been attained, and a means or system wherein the'waste heretofore had is largely avoided;

I accomplish the objects of my invention by the construction herein shown.

In the accompanying drawings illustrating one embodiment of my invention and in which like characters 0 reference indicate like parts,

Specification of Letters Patent.

lntcntcd June 3. 19 19.

Serial No. 217,160.

Fig. 8 is a detached view of a section of the heating drum.

()ne of the great problems in heating a dwelling or other huilding is the (lifliculty of utilizing thc hcat :urtually generated by the heating means and of conducting the heat units to the dcsircd point.

For illustration in a steam heating plant it becomes necessary to hcat the water in the boiler, which must result in heating the boiler itself and all appliances connected therewith, thus wasting a large amount of the heat units at the outset. Thc whole circulating system must then he hcutcd in order to conduct the steam at a sufiicientlv high tcmpcraturo to the room to he heated. It then becomes necessary to supply sulli cient heat to heat a radiator, thus again taking up the heat units before they reach a point. where the room begins to receive th benefit of the heating-system. It is a wel known fact that a large volume of the heal units are carried away in smoke and other products of combustion so that but a cour paratively small pcrcentage of the heat generated by the heating means is in fact utilized for heating purposes:

Inorder to overcome this condition and provide a means whereby the heat actually generated at the source may be readily absorbed, given oii' and conducmd to the de sired point I avoid the use of heavy, thick material and'provide a construction wherein the heat units may be rapid] athsrad carried to the point desired e orev the ten. perature is materially reduced.

The first step to accomplish the result to be attained comprises the employment of one or more heating drums each constructed by preference, as at present advised. as shown in Figs. 4, 5, -(i and 7. This drum comprises an outer shell 1, formed of thin material, preferably sheet copper or brass and by prcfcrcuce having its surface con rugated. \Vithiu the outer shell I arrange an inner shell 2 of like construction and ar range the some substantially as shown in Figs. 4, (i and 7. The bottom of the shell 1 is open, while the bottom of the shell 2 is closed. Both shells are open at the top. Between the outer and inner shells of th heating drum I prefer to arrange a basket like structure similar to that shownin Fig. 2.

Referri now to Fig. 4, heat is applied to the lower open ended portion 4 and it will be readily seen that the heated air will pass upwardly between the shells l and 2 and become rapidly absorbed by these shells, and as the shells have large corrugated radiating surfaces, with their corrugations arranged to ballie the heated air so that in its passage upward between said shells it will be deflected back and forth from one to the other, they will generate intense heat and give it off in great volume. If, now, an arrangement be made so that the air currents will flow up between these two shells, the air will become heated and if the air so heated be quickly conducted through proper conduits to the rooms or places to be heated, a very much larger percentage of the heat units will be utilized for heating purposes than has heretofore been found possible.

The employment of a heat radiating member, such as the basket-like structure 3 shown in Fig. 2, arranged between the outer and inner shells of the drum serves to break up and further heat the air currents and bring all particles in contact with a heated surface, thus insuring the thorough heating of all the air passing between the shells of the drum.

In Fig. l I show a construction wherein the heat absorbed by the inner shell will be permitted to flow upwardly and because of the employment of a dish shaped deflecting plate 5 will be deflected dowmvardly and be again thrown in contact with the heating drum, and will then pass upwardly in its outward travel in substantially close contact with the upper portion of the inner shell and thus be further heated and conducted to the desired point, so that in the construction shown in Fig. 4 the heat units absorbed by the air in contact with both the inner and outer shell may be utilized.

In Fig. (l I illustrate two drums opening at the top into a conduit 22, and an arrangement whereby air is allowed to enter the inncr'and bottom portions of the inner shells 2 through an approximately vertical conduit 6 having horizontal branches 23 which turn downwardly and open above the closed bottoms of said inner shells. The air thus introduced into the inner shells 2 is projected or descends onto the bottoms of said shells, and then rises in contact with the sides of said shells, and to this end the outlet terminals of the' branches 23 are surrounded with annular deflectors 33. T he intake of the conduit 6 must be below the level of the open bottoms of the shells 1, in an inclosure to which particular reference will subsequently be made, with the discharge ends of said conduit or of its branches 23 just above the closed bottoms of the shells 2, as previously observed. Thus the passage of air into the shells 2 is insured, and the air is discharged at the points where it is subjected to the most intense heat.

Suitable dampers 7 and 8 are provided for the heating drums in the conduit 22 for regulating the flow of air from the heatin drums, and for cutting off either of sum drums. r V

The drums in this view, Fig. 6, are heated by means of gas-burners 51 on a T 52 at the inner end of a pipe 53 which receives its supply from an outside pipe 54.

In order to facilitate the flow of the heated air I prefer to arrange a fan 9 in the conduit 22 preferablfy driven by an electrio motor 10, which n will operate to force the air u wardly to the desired point.

In Fig. 6 I s row an arrangement of water tanks 11 designed to moisten the heated air on its passage.

In Fig. 7 I illustrate a construction wherein coal coke or other like fuel may be conveniently employed and with this arrangement I prefer to employ a reservoir 12 arranged at an elevation above the fire box 13 with a conduit 14 extending between the two and I provide a fan 15, driven by a motor 16, the fan being arranged in a conduit 17 extending to the ash box 18, by the employment of which fan a forced draft may be had and a more complete combustion attained. In this figure I also illustrate the employment of a hot air fan 9, driven by a motor 10. The conduits 19 and 20 lead to a chimney and thus dispose of the products of combustion, but as the smoke and other heated products of combustion pass upwardly between the corrugated outer and inner shells of the drums the heat units will be absorbed so. that the smoke and gases 'will passiout through the chimney, after having given off substantially all of the heat units carried by them. The heat unitsgiven oil' by the outer surface of the outer shell 1 of the drum will pass upwardly and through the conduits 21 connected with the on la of the furnace and are mixed with the cat units which pass upwardly from the interior of the drum thelatter being forced upwardly by the an as before described.

Air, as before described, is admitted to III mamas means ma be employed to heat the drum, it simply eing necessary to rovide means which will furnish heat to t e lower open end portion of the outer shell 1 of the drum, or in other words to provide means for furnishing heated air to pass upwardly between the outer and inner shells and, as before stated, it is also desirable to provide means in many instances for the flow of air to the interior portion of the inner shell of the drum so that the heat units to be given off by the shells may be utilized for heating purposes. It will therefore readily be seen that the employment of gas, kerosene, electricity or other means for heating may be employedwith my device. I

Electricity might be employed as a heat-' ing means, and one way in which it could be applied would be through the medium of .a resistance coil or similar element located'at the base of the drum or drums.

I do not limit myself to any particular means for furnishing heat and applying the same to the drum or drums.

It will also be seen that the arrangement of conduits, dampers, fans and deflecting devices may also be arranged and com structed differing in detail and location from that shown by me without departing from the spirit of my invention, and I therefore do not limit myself to the construction shown, but refer to the same'as one embodiment of my invention.

The cupola in which the conduits 21 are located is mounted at the top of an inclosing structure 25 having at the top deflector members 24 which direct the'heat waves from the drum or drums below to said cupola. This structure or inclosure is made with the end in view of conducting the heat generated by the inclosed drum or drums to the conduits 2'1 with as little loss as possible. The aforesaid drum ordrums are supported within the inclosure 25, in the presentainstance, by being suspended from a light cross bar 30 having its ends seated in brackets 31 on opposite sides of said inclosure." i

The urpose of the inclosure 25 is to conserve. t e heat radiated from the outer'sh'ell or shells 1 and thus to insure'the utilization of practically all of. the heat generated by the drum or drums for heating the rooms to which it is conveyed by way of the conduits 21. The construction of the apparatus as a whole is such that little or no heat is given oil from the inclosure 25'into'the space surf roumling the same, but; is conveyed away,

l t rough the top of said inclosure:

The ofllfie of the fan 9 is threefold era-st,

the action of the fan draws the air into the. shell or shells 2-through theconduitfi or 6"; second, said action sucks the air out-of the top of said shell orshells, and out of the top ofthe shells 1 in the Fig. 6 construction;

1 taken from -be'lowthe heating and comparative y fresh and lively closed at the bottom,

and third, said action forces the air Mpwardly toward the conduits 21. This is an important and .valuable feature of the invention. y

Air from the outside is an plied to the inclosing structure 25 throng a conduit 50, Figs. 1,6, and 7, which opens into the back side of said structure. i

The air supplied to the interior of the shell or shells 2, in either example herein shown, being of the temperature of the air in the inclosure 25, from which it is taken, is in consequence more uniform or evenin tfimperature and much better adapted for t e urp'oselforwhich it is used than would? 4 outside. And the uniformity or evenness is enhanced by reason of thefact that the air is oint or points, thus bein cool without being cold,

as is needed for the supply to the shell or shells 2. Having therefore described my invention whatI claim .as new and desireto secure by Letters Patent is:-'
