OIL BURNING HEATING APPARATUS.

THEODORE LEMBKE, OF BUFFALO, NEW YORK.

OIL-BURNING HEATING APPARATUS.

Specification of Letters Patent.

Application filed. March 30, 1909. -Sria1 No. 486,681.

To all whom it may concern:

Be it known that I, THEODORE LEMBKE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Oil-Burning Heating Apparatus, of which the following is a specification.

This invention relates to an improved oil burning heating apparatus and the object of the invention is to produce an apparatus for heating buildings In which oil serves as the heating agent.

Another object of the invention is to construct the burner in such manner that the combustion chamber can be entirely inolosed as to exclude all air except that which enters through the burner and thus obtain a more even combustion and a greater degree of heat.

Another object is to so construct and arrange the heating chamber that the heat is utilized to the fullest possible degree in heatin the air as it passes therethrough and thus e ect a decided saving in cost of operation.

The invention also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which,-

Figure 1 represents a central vertical longitudinal section through the furnace of the improved apparatus showin a side elevation of the remainder thereo Fig. 2 is a horizontal section through the furnace on line a a, Fig. 1. Fig. 3 is an enlarged detached sectional view of one of the burners.

In referring to the accompanying drawings for the details of construction, ike nu merals designate like parts.

The furnace of the improved apparatus consists of a combustion chamber 1, a heating chamber 2, .-an outlet chamber 3 communicating with the stack 24, and a supplementary heating chamber 4 extending around the ends and outer side of the outlet chamber and forming an auxiliary passage for air.

The combustion chamber 1 is inclosed by side and end walls 5, 6, 7 and 8, and top and bottom brick walls 9 and 10, so that it is wholly inclosed and walled in with fire.- proof material.

The rear wall 8 of the combustion chamher 1 forms the separating partition be panded in openings in the plates to securely fasten them therein. Transverse openings 14 armtormed 1n the vertical wall 8 and reg ister with the fiues 13 so as to provide uninterrupted passage from the combustion chamber'l to the outlet chamber 3.

A pipe 15 leads from the outside ofgthe building through the side wall of the -fiirnace and communicates with the heating chamber 2 forming aninlet passage for unheated air. Another pipe 16 is connected at its end to the opposite wall of the furnace and provides a passa e for conducting the heated air from the urnace to the various fines or pipes leading to the different portions of the building.

A fan 17 is located in this outlet pipe 16 and serves to draw a current of pure fresh air into the heating chamber 2 through the inlet pipe 15 and then after it is thoroughly heated into and through the outlet pipe 16 to the pipes or fiues for conducting heated air.

The rear supplementary heating chamber 4 is separated from the outlet chamber 3 by a vertical metal plate 18 and a similar plate 19 forms the rear wall of said chamber.

The heating chamber 2 and the outlet and supplementary chambers 3 and 4 are closed at the sides, top and bottom by metal plates 20, 21, 22 and 23, the top plate having an opening out therein directlyabove the'outlet chamber for the escape of gases into the stack 24.

The supplementary heating chamber 4 is of a narrow elongated form extending longitudinally of the furnace and has its ends extending at substantially right angles to extend in heating proximity to the ends of the outlet chamber and also to provide passages,

25 and26/ which communicate respectively with the inlet and outlet pipes 15 and 16, see Fig. 2.

The burner consists of a pipe 27 leading through the side wall 6 into the combustion chamber 1 and a pipe 28 of smaller diameter which enters the pipe 27 outside the combus-.

. tion chamber and extends but a short disoil through the pipes 31 and 28 into the pipe 27 which constitutes in reality a blast pipe t-ance within said pipe.

The pipe 27 is connected by a pipe 29 to a tank 30 adapted to contain compressed air, and the pipe 28 is connected by a pipe 31 to a tank 32 which serves as a reservoir for the,

oil.

An air compressor 33 is .connected to the compressed air tank 30 by a pipe 34 and also to the oil reservoir 32 by a pipe 36 to supply air thereto. By forcing air 1nto the reservoir the oil is fed into the pipe 27 within the combustion chamber. i

The pipes 29, 31, 34 and 36 are-provided with valves 37, 38, 39 and 40 by means of which they may be closed against the passage of air or oil.

The air compressor is driven by a belt 41 .which runs on a pulley 42 on the comfrom whence it is ejected. The compressed air an the oil are united as they leave the nozzle and burn with an intense heat in the combustion chamber.. From the combustion chamber the heat passes through the flues 13 which become heated to a high temperature, and into the outlet chamber from whence the remaining gases pass out through the stack. As the a r 1s drawn into the heating chamber by the fan 17 ifithe passage 16 it comes into contact with the heated flues and imme- .diately becomes heatedand then passes on\ through the passage 16 into the flues leading to the diflerent portions of the building. The air in the supplementary heating chamber 4 which is heated by contact with the metal plate formin the rear wall of the outlet chamber, is rawn into the heating chamber throu h the connecting passage by the suction of t e fan.

By referring to Figs. 1' and 2 it will be noted'that the flues are staggered so that no air currents can pass directly throu h the heating chamber but must pass aroun them in a' sinuous course. In this way the air is quickly and'thoroughly heated to such a tem erature that all-germs'and foreign matter is destroyed.

The currents of air in passing through the heating chamber move in a direction approximately transverse to or across the flues so that the heat units thrown off by the gases of combustion passing through the flues are fully and efliciently' utilized. 1

When starting the furnace a number of bricks are removed from the wall of the mace, a bottom wall, a top wall havin combustion chamber except through the blast pipe.

One or more burners can be used, the number varying with the size and capacity of the apparatus.

In this construction the four chambers of which the furnace consists are arranged side by side in a horizontal row as shown in Figs. 2. I I

One of the principal advantages of this improvement is that the products of combustion are entirely isolated from the air so that they cannot contaminate or become mixed with the air as it is passing through the furnace.

Another advantage resides in the thorough and eflicient manner in which the heat is utilized, air being drawn through the heating chamber bet-ween the flues and also around the outer side of the outlet chamber which practically forms a continuation of the heating chamber as one end of the flues extends through the wall between the heating chamber and the outlet chamber and conducts the heated products of combustion to'said outlet chamber.

I claim- 1. A furnace having side walls, end walls provided respectively with an inlet and outlet for the passage of air through the furnace, a bottom wall, a top wall havin an outlet opening for-thev roducts of com ustion, vertical longitudinal and transverse -partitions extendin between the-bottom wall and the top wa and dividing the interior of the furnace into a plurality of chambers, there being a comparatively large chamber centrally located and forming a heating chamber, a chamber on one side of the heating chamber forming a combustion chamber and a chamber on'the opposite side of the heatin chamber forming an outlet chamber and ein in communication with the outlet opening in the top .wall and a lurality, of flues havin their ends exten ing to and through the ion 'tudinal partitions formin the side walls 0 the heatin chamber an afiording communication etween the combustion chamber and the outlet chamber and a chamber'extending on the exterior of the outlet chamber forming a supplemental heatin chamber, the said outlet chamber exten ing substantially across one side/and from top to bottom of said furnace and the outer wall of said outlet chamber forming the inner wall of said supplementary heating chamber.
