SPECIFICATION forming part of Letters Patent No. 256,345, dated April 11, 1882.

Application filed January 26, 1882. (No model.)

T o all ywhom it imag/'concern' Be it known that I, JAMES H. MAOKINTOSH,

of Paterson,in the county of Passaic and State the same, partly in section through the broken line au m, Fig. 1. Fig. 3 is a sectional side elevation of a portion of the lower part of the same, taken through the .line yy, Fig. 2.y Fig. 4 is a side elevation ot' a portion of the upper part of the same. Fig. 5 is a sectional elevation of a part of the coldair inlet-pipe. Fig. 6 is a side elevation, partly in section, of one of the airheating tlues. Figs'. 7, 8, andv l0 are sectional plan views of different forms of airheating dues. Fig. 9is a sectional elevation ota part ot' one of the aiuheating lines, taken through line .e e, Fig. 8.

'The object of this invention is to promote etliciency in heaters, provide pure air, and facilitate the controlling ofthe heated air.

. Theinvention consistsin theair-heatingtlues provided with projectionson the inner surfaces projecting alternately from opposite sides and extending beyond each other; also, in the airheating tlues havinglongitudinal lslots or open-V ings and provided with projections on theirinner and extended surfaces; also, in the combination, with the heating-tlues provided with the projections on the outersurtaces,of theinclosing-case provided with projections on its inner surface; also, inthe combination, with the case, the top and bottom plates, and the airheating tlues, of a pipe having a stopcock, whereby the air that collects iu the upper part of the water or steam space can be readily drawn oft', and also in the combination,with the top plate and the perforated cover having dampers, of radial partitions and one or more pipes, whereby a part or all of the heated-air can be used for heating other rooms, as will be hereinafter fully described. A represents the outer case or shell ot' the heater, which may be made cylindrical or of any other desired oreonvenientshape. Around the upper and lower ends of the case A are formed outward'ly-projectin g flanges, which are perforated to receive the bolts that secure the said-case to the top and bottom plates, B.

In the top and bottom plates, B, are formed numerous round holes to receive the upper and lower ends ot' the air-heating tubes or tlues C. The ends of the iiues C are made round and are fitted a-ir and water tight in the holes in the plates B. The bodies ot" the Vtlues C may be made, round, oval, triangular, or of any other shape, as may be desired,or as the form to be given to the heater mayrendermost convenient.

The iiues C may have longitudinal slots or openings D formed through them, as shown in Figs. 6, 7, and 10, to increase theflieating and heat-absorbing surfaces. For the saine purpose the inner surfaces of the fines C can be roughened, or can have projections,E formed upon them, as shown in Figs.7, 8, 9, and 10.

Upon the outer surface ot' the heating-lines C are formed outward projcctions,'E, and upon the inner surface of the case A are formed inward projections, E2, which projections E E2- greatly increase the heatabsorbing surface presented to the heating medium introduced into the space surrounding the tlues U and inolosed by the'ca'sc A, and thus increase the efficiency of theheater.

In theoppositesides ot' theeaseAareformed bulgesF,to form spaces to receive the ends of leading from outside the building, and whichv is provided with a hinged damper or valve, J, opening inwardly. The damper or valve J is made of such a weight that as the air'within the iues is heated and rises the pressure ot' the outside air will raise the said valve J more or less, `and thus enter the heater, so that the supply of cold airywill be regulated automaticallyby the amount ofheat applied to the heater.

When hot water or steam is used as the heating medium the air that may collect in the upper part of the space around the ues C can be drawn off through a small pipe,K, connected at its upper end with the upper part of said space, and connected at its lower end with the air-inlet iiue I, or with a water-pan placed in the base of the heater.

The water-pan is not shown inthe drawings, as there is nothing new in its construction or use.

The pipe K is provided with a stop-cock,L, so that it can be opened and closed as required. When the cock is open the air in the upper part of the heater, being under pressure, will countexbalancethe atmospheric pressurein the inlet-pipe or water-pan,and consequently would be forced out of the said upper part through the said pipe.

The case A is placed upon a base, M, which is provided with a molding, N, to cover the bottom ange of the said case and the fastening-bolts, as shown in Fig. 1. The base M has a number of openings, O, formed through it,aud is provided with sliding dampers P, having corresponding openings, so that the air from the room can be admitted to thc heater,

heated, and discharged into the room without introducing outside air, when desired.

The top plate B of the heater is provided with a cover, Q,which may be arched,as shown in Fig. 1, or made fiat, and which has numerous openings, It, formed through ity to allow the heated air to escape into the room.

The perforated cover Q is provided with slidedampers S, which are made in sections,so that more or fewer of the openings 1t can be covered, as desired. The middle part of the cover Q is supported by a solid or tubular standard, T, to which are hinged or pivoted a numberot' radial partitions, U, which are so formed as to fit the space between the top plate B and the cover Q, as shown in Fig. l.

The partitions U can be adjusted to divide the space between the top plate B and the cover Q into two or more sections or compartments, with which are connected the inner ends of one or more air-pipes,V, so that by adjusting the sliding dampers accordingly a portion or all ofthe heated air can be sent through the pipes V into other rooms, whereby several rooms can be warmed from the same heater, if desired.

In Fig. 2 the dampers and partitions are adjusted to send the heat into three rooms--two besides the one in which the heateris arranged; but it is evident that the number can be increased or decreased without departing from the nature of my invention. The cover Q is provided with a molding,W,forornamentation and to cover the top flange ot thc case A and its fastening-bolts.

Havn g thus described my invention, I claim as new and desire to secure byIJetters Paten t- 1. In a heater, the air-heating fines G, pro vided with the projections E on their inner surfaces projecting alternately from the opposite sides and extending beyond each other, substantially as and for the purpose set forth.

2. In a heater, the air-heating iiues G,longi tudinal slots D formed through them, and provided with the projections E on their inner surfaces and the projections E on their external surfaces, substantially as and for the purpose set forth.

3. In a heater, the combination, with the heating-dues C, provided with the projections E on their external surfaces, of the inclosingcase provided with the projections E2 on its inner surface, substantially as and for the purpose set forth.

4. In a heater, the combination,with thecase A, top and bottom plates, B, and air-heating ilues G, of the pipe K, having stop-cock L, substantiall y asherein shown and described,where bythe air that collects in the upper partofthe water-space can be readily drawn oit', as set forth.

5. In a heater, the combination, with the top plate B and the perforated cover Q, having dampers S, of the hinged radial partitions U, and one or more pipes,V, substantially ashorein shown and described, whereby a part or all of the heated air can be used for heating other rooms, as set l'orth.
