Application liled July lG, 1888. (No model.)

To all whom it may concern:

Be it known that I, W'ILSON ERNsT, a citizen of the Unitedl States, and a resident of the city and county of Camden, and State of New Jersey, have invented a new and useful Improvement in Heaters for Heating;` Buildings, &e., of which the following is a specification.

The object of my invention is to provide a heater to be used for heating buildings, cc., inexpensive and simple in construction, easily understood .and managed, and free fromy the objcctions that apply to many other heatcrsviz., dust, smoke, and an enormous waste of heat, which entails a great expense for fuel'n The accompanying drawing represents a vertical section of my invention, and clearly represents its construction and Operation.

A is the furnace, which is preferably made of cast-iron, and may, if desired, be made in the form of a truncated cone. y

B is the smoke-pipe, whicheommunicatcs with the furnaee at its top, and which passes through the chimney C. W

D D are pipes or openin fresh air to the furnace.

E E are openings or pipes for supplying air to the space surrounding the smoke-pipe.

F is a case surrounding the furnace, and around which'the fresh air passes, as indicatcd by the arrows.

G is the grate.

His the base-plate upon which the furnacc stands.

I is the ash-pit.

O O are dampers, and K, L, and `lVI are registers Opening, respeetively, upon the first, second, and third floors of the building`-to*be heated.

My furnace A is constructed of cast-iron, 40 and, as will be seen from the drawing, is exceedingly simple, containing no more parts than an ordinary stove. v

The smoke-pipe B is connected with the: furnace at its top, and passes up through the chimncy O to a point, N, which is just above the register on the highest floor to beH-heated. At this point the chimney is shut off by a partition, N. The air to be hezted is introduced through pipes or openings D D, at the top of the furgs for supplying 25 nace, and passes down alougside of the case F and up alongsidc of the furnaee, where it becomes greatly heated. From here it passes to the chimney or warm -air flue O, and through the registers into the rooms to be hcatcd. This is the natural way for air to travelflthe cold air down and the hot air up.

A. great amount of heat is wasted in all heaters that I am aware of by escaping from the tep of the chimney and by striking downward from the fire. To prevent the loss of heat through the smoke-line, I have it inclosed, as shown, in the ehimney, and as the heat will strike out through the smoke-pipe it will heat the air in the air-chiinney or warm-air flue, and pass from there into the rooms to be heated. To utilize the heat which strikes down from the fire, I have the basc drawn in, as shown. This base will become very hot, and will give off its heat to the air which is admitted through 1), and which pass/es around F, as shown.

To prevent dust :from entering the hot-air flues and passing from thence to the rooms of the building, I have the base l-I, on which the furnace rests, extending completely across the ash-pit. This shuts off all communication between the ash-pit and the air-chambers and hot-air flues. By this same arrangement all smoke is prevented from entering the hot-air iiues.

Along the chimney or hot-air ilue O, I have openings E, which communicate with the open air, and through which a supply of fresh air may be introduced into the hot-air flue to take the place of that which has passcd into the rooms of the building. This air is very rapidly hcated from the smoke-pipe B, and my plan of admitting cold air to both the furnace and hot-air flues is in kceping with the natural action of cold and hot air and secures quick action, carrying the'heat generated at oncewhere wanted, and preveuts the waste of heat which occurs when the action is not so rapid, while my plan of incasing the smoke or draft pipe utilizes a very large amount of heat that otherwise goes to waste. These economies of heat naturally decrease the amount of fuel necessary for heating purposes. The hotair flue O is furnished with dampers O, by Ioo means' of w'l'leh the hot air may be all turned into one room, or maybe allowed to mss up the flue. These dzmqjmrs are similar in construction and Operation to those usuaUy sed for like purposes, and will need no h'lrther description.

l am awal'e that the ntl'odueton o" fresh alr into the hot-an1 fine of a heater, and the lncaslng of the smoke-pipe in the hotar flue are not new; and I am also aware that a defleetng-platehas been used in connection with a stove to assist in utilizng the heat which eseapes from its front, and therefore do not elaim these broadly; but XVhat I do elam is-- 1. rJPhe combination, 111 a heater, of the stovo 2 v esama A, smoke-ppe B, hot-air fiue O, dampers'O7 oo1d-airn1ets E and D, and ammlar t F, snrroundng the stove and dviomg the' strikes down from the grate G of a stove or heater, the base H, contraeted on all sdes at a point below the gl'ate, substantially as shownv and described.
