HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 559,807, dated April 28, 1896. Application filed July 17, 1895. `Serial No. 556,279. (No model.)

To @ZZ 10700772, z'f muy 0077.067172.`

ie it known that I, WILLIAM I-I. PAGE, ot Basic City, county of Augusta, State of Virginia, have invented certain new and useful Improvements in Heating Apparatus, of which the following' is a specification, reference being had to the accompanying drawings.

The object of my invention is to provide a heat-radiating drum for use in connection with stoves, furnaces, or other initial heaters so constructed that the maximum heatradiating surface will be obtained in the smallest possible compass and that a free circulation of air over the heated surface will be provided for.

In the accompanying drawings, Figure I is a perspective view of my drum, showing the envelop partially broken away. Fig. II is a central vertical section. Fig. III is a transverse section on the line 3 3 of Fig. I. Fig. IV is a view of the envelop detached. Fig. V is a view of a modiied form of my drum.

Referring to the figures on the drawings, l :indicates the body part of my drum pierced by diametrical air-lines d and al, extending substantially to the top and bottom of the body part and defining a plurality of sector shape longitudinal s1noke-iiues 5, which latter open at their opposite ends into terminal domes (i and 7, formed by the collars 8 and caps 9. It is obvious that this general design may be obtained by any suitable construction, the several parts being cast in the most convenient forms and united in the usual manner. In the drawings, however, is illustrated a construction which I have found to be simple, eflicient, and inexpensive. In this preferred construction the smoke-fines are formed, respectively, of a plate 10 bent at right angles and constituting a partition-wall between the smoke and air iiues and having their lap edges ll bent to conform to the cylindrical body part.l The exterior plates l2 constitute the exteriorwalls of the smoketlues and are clamped to the lap edges of the plates 10 by bolts passing through longitudinal brace-rods 13 within theinterior and similar rods Il upon the exterior of the smoketlues.

The plates 12 extend beyond the edges of the collars 8 andare clamped thereto by the curved end brace-rods 13 and le, secured to the collars 8 by terminal bolts 15, which pass through the rods 13a, collars S, and the eX- tremities of the rods 13 and are provided with nuts IG upon their extremities, as usual..

The exterior plates l2 are provided with notched corners 17 for the reception of the bolts l5. By this means it is unnecessary to entirely remove the end brace-rods when it is desired to remove the exterior plates l2 for cleaning, as will hereinafter more clearly appear.

The air-lines are closed at their top and bottorn by frames IS, which iit closely between the plates l0, and are securely clamped between them by bolts i9, passing through the adjacent walls of the smoke-fines to secure the parts against displacement and seal the joints without the intervention of solder or similar seals.

The plates l0 preferably extend somewhat beyond the frames 1S to form a soot-receptacle 20, which serves to collect the soot and'prevent its accumulating upon the sides of the air-dues.

The caps are formed, as shown, with a conical part and a cylindrical continuation thereof adapted to iitin or around the adjacent scctions of a stovepipe through which the prod ucts of combustion pass from a stove or initial heater. i

The periineters of the caps project a considerable distance beyond the body part and are preferably turned down upon the annular flanges 2l of the collars S. The purpose of these projecting perimeters is to securely retain between them a spirally or otherwise tinted envelop, the tlutings of which extend beyond the edges of the caps and open into the atmosphere.

Supposing my drum to constitute a section of the escape flue or pipe through which the products of combustion pass, it will be observed that the heated products will pass through the smoke-dues of the drum and out at its upper end. The heatingot the drum will cause the atmosphere of the room to pass into the flutes of the envelop at their lower ends and will cause it to circulate over a part of the exterior surface of the body part and IOO through the diametrical passages, escaping iinally at the top of the iiutings upon the opposite side of the drum. Not only will a free circulation to the full capacity of the diametrical air-fines be maintained, but a constant circulation lwill be kept up through the iiutes adjacent to the exterior walls of the smoke-dues.

In the event of the accumulation oi' soot and the like within the smoke-fines it is only necessary to remove the longitudinal bracerods and loosen the bolts of the end bracerods, when, as will be apparent, the top and bottom edges of the plate l2 may be slipped from under the last-named rods, the replacing of the plate being accomplished with equal facility after removal of the debris.

As I have hereinbefore mentioned, the details otl construction are susceptible of wide variation. For instance, as shown in Fig. V, instead of constructing the smoke-fines from a number of plates and bracing them with lon-` gitudinal brace-rods they may be constructed of a single plate bent to produce the required design, the adjacent edges of each flue being seamed together and the various f'lues being retained in their proper relative positions by the collars of the caps which in this construction encircle the outside plates of the flues. I do not therefore desire to limit myself to the details of construction herein shown and described, but reserve the right to modify and vary them at will within the scope of m5 invention.

Vhat I claim isl. A heating-drum, the body part of which is formed of separate longitudinal smoke- 'tlues open at their opposite ends and defining` between their walls a diametric air-flue extending entirely through the body part and continuously from the top to the bottom of the body part, the top and bottom of the airtlue being closed, substantially as specified.

2. The combination with a body part, of a drum composed of a plurality of separate smoke-fines defining between their walls a plurality of diametric air-flues, the smoke- 'fiues and air-fines extending continuously from the top to the bottom of the body part, and the air-fines extending entirely and unobstructedly through the same, caps upon the opposite end of the body part communieating with the smoke-fines and having no communication with the air-flues, substantially as specified.

3. The combination with a drum having its body part composed of separatelongitudinal smoke-nues defining a diametric air-flue, the smoke-fines and air-fine extending the entire length of the body part, the air-flue extending entirely through the body part transversely and having its top and bottom closed, of an envelop surrounding said drum and communicating with the exterior atmosphere and with the air-fines, whereby the air is caused to enter the bottom of the envelop, to circulate through the air-flue of the drum and to finally escape from the top of the envelop at the opposite side of the drum, substantially as specified.

4. The combination with a drum, the body part of which is composed of a plurality of separate smoke-fines defining a diametric airfiue coextensive with the smoke-fines and extending entirely through the body part, of an envelop surrounding said drum and provided with spiral flutings communicating with the exterior atmosphere and with the air-ilue and traversing the exterior wall of one or more of the smoke-flues, substantially as specified.

5. The combination with a drum having a plurality of longitudinal smoke-fines defining a plurality of air-iiues extending entirely thro ugh the drum, oi' projecting caps from the opposite ends of the drum, and an envelop confined between the perimeters of said caps and having flutings projecting beyond the edges of the caps opening into the atmosphere and communicating with the air-fines, through the drum, substantially as specified.

G. In a heating-drum, the combination with terminal collars and brace-rods secured at their opposite ends to their collars, and smokefines composed of a plurality of plates secured to said brace-rods, substantially as specified.

7. In aheating-drum, the combiifiation with terminal caps, of a plurality of smoke-'fines secured at their opposite ends, respectively to the caps and separated to define diametric air-fines extending entirely through the drum and longitudinally coextensivc with the smoke-fines, substantially as specified.

S. In a heating-drum, the combination with the collars, top and bottom frames I8 and separate longitudinal smoke-flues, of means for securing the frames 18 to the collars, and mea'ns for clamping the smoke-fines against the sides of the frames I8, substantially as specified.

9. A heating-drum having a plurality of airlues provided, respectively with separate, independent, exterior plates, substantially as specified.

l0. In a drum, the combination with separate longitudinal smoke-fines, of a frame 1S secured between the smoke-lines slightly below their ends, the extremities of the smokeilues and the frames 1S constituting a sootreceptacle, substantially as specified.

In testimony of all which I have hereunto subscribed my name.
