ALEXANDER MCARTHUR, OF ALEDO, ILLINOIS.

VENTlLATlNG-HEATER.

SPECIFICATION forming part of Letters Patent No. 366,855, dated July 19, 1887.

Application ledJnly22,1SS6.

To @ZZ when it may Concern.:

Be it known that I, ALEXANDER MCAR- THUR, a citizen of the United States, residing at Aledo, Mercer county, Illinois, have invented a new and useful Improvement in Ventilating-Heaters, of which the following is a specification.

My invention relates to improvements in ventilatingheaters in which a Ventilating apparatus consisting of an outside drum, a series of ringed partitions, and an interior smoke-passage containing two or more deilectors operates in conjunction with an ordinary heater; and the object of my invention is to furnish aventilating-heater which shall be thorough in its work and economic in its use. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l representsa full view of my invention, showing a vertical crosssection of the ventilatiiig-heater. Fig. 2 shows a top View of my ventilatingheater. Fig. 3 represents one of the series of ringed partitions.

Similar letters refer to similar parts throughout the several views.

In my drawings, A represents a common heater, which is provided with the top plate, B, having flange b, and the flanged opening b', through which the smoke escapes.

C is a drum, which tits over flange b upon top plate, B. Inside of drum C is the smokepassage D, which fits upon the flanged opening b', and vpasses to the top of the drum C, where it terminates in a narrowed opening or mouth, d, of such size as to t an ordinary stove-pipe joint. Inside of the smoke-passage D are the deliectors E and E, prefera bly conical in shape, and with their vertex pointing downward, as illustrated in the drawings. These deflectors are fastened to the walls of the smoke-passage, and of such size as to leave sufticient space 'for' the smoke to pass. By means of drum C and the smokepassage D, passing through the same, there is formed a chamber, F.

G is a fresh-air-supply pipe, entering the room where my heater is to be used from outof-doors, and passing into chamber F near its base.

This fresh-air pipe G is preferably of Serial No. 208,773. (No model.)

the shape as illustrated in the drawings, and has the cap g', which is removable, and the damper h. The chamber F is partitioned off by a series of ringed partitions, f', f2, f3, and f", as illustrated in the drawings, of which the lowest partition,f, is placed just above where the supply-pipe G enters the chamber. Each of these ringed partitions is partly eut away, so as to leave an opening, y, from one division formed by these partitions to the neXt above. These openings in these ringed partitions are so arranged in respect to each otherj that should a line be drawn passing through each opening g in the partitions it would be in the form of a spiral around the smoke-passage D. Fig. 3 shows one of these ringed partitions. K is an opening in the top of my Ventilating-heater, and it corresponds with the openings in the ringed partitions.

The operation of my invention is as follows: From the tire-box of my heater the smoke and heat passes directly up into the smoke-passage D. Here it is deflected by the deflectors E, so as to retard its passage and to bring the heat into more direct contact with the walls of the smoke-passage. From here the smoke passes up into the stove-pipe. The fresh-air current entering from outside through pipe G passes from pipe G into chamber F below the lowest ringed partition, f. From here it passes through the opening in this partition up into the next highest division, and up through the next opening to the one above. By virtue of the spiral arrangement of the opening g around the smoke-passage a fresh current of air is led around and brought in constant contact with the heated surface of the sn1okepassage, and is thus heated, until it finally arrives at the top of the drum, when it passes out into the room through opening K. rIhus a constant current of fresh heated air is supplied to the room. If it is found desirable not to warm this supply of fresh air introduced into the room inthe manner described, the damper h may be closed and the cap g removed. In that case a current of fresh air is introduced directly from the supply-pipe into the room.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The combination, in a heater provided with IOO an outer and an inner wall forming a smokepassage, D, and an air-passage, F, of the ring parttionsf, ffa, andf, secured one above the other in the passage F, each of said parti- 5 tions being cut away to form openings g, and

said openings being arranged spirally around the smoke-passage, deectors E, suspended in the smoke-passage, and an air-pipe entering the air-passage and an opening ab the top, substantially as described.
