- Specification of Letters Patent. Patefited Aug. 15, 1911.

Application filed May 4, 1311'. Serial No. 624,925.

Be it known that I, FREDERICK MOENCH, a citizen of the United States, residing at Lesueur Center, in the county of Lesueur and State of Minnesota, have invented a new anduseful Peat-Burner, of which the following is a specification. v

It'is the object of the present invention to provide a furnace of novel and improved construction, in which peat, or' any other combustible 'material, may beburned, to

raise the temperature of a coil withilrthe furnace, through which coil, the heated fluid is pumped, a forced feed thus being provided, whereby-the furnace may be located at considerable distance from the building to be heated. J

A further object of the invention is to provide a novelform of heat-interchanging element, adapted to be interposed into a cir the interchanging element" culatory system, being so constructed that it may be used .either as a heating structure or as'a refrig erating structure.

A further ob ect of the invention is to provide a novel form of furnace.

'With the foregoing .and other objects in view which will appear as .the description proceeds, the invention resides in the combination and arrangement. of parts'and in the details of construction hereinafter describedandclaimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the'scope of what is claimed without departing from the spirit of the invention.-

This frame constitutes a support for the grate, denoted generally byithe numeral 6.

-The grate 6 is in the form of a sinuous pipe,

extending backwardly and forwardly, across the furnace. As denoted by' the numeral 7 ,ftheends of the several convollr tions of the pipe grate 6, rest upon the frame 5, the outermost convolutiqns of the grate 6 resting upon the frame 5, throughout their entire extent, and aldng: the sides of the furnace, as denotedby the numeral 8 The sinuous pipe which forms. the grate 6' is carried upwardly, in; superposed convolutions, along the sides 'ofsthe furnace, as shown at 9, the convolutions 9 beingcarried acrossthe top of the furnace, in the interior thereof,.- as shown at 10. Theconstruction,

therefore, is such that there is a continuous, sinuous pipe line within the furnace, ex-

tended entirely around the furnace. in the interior of the same,

to define-a fuel chamber l1.

- Access is had to the-fuel chamber 1lthrough a hinged mounted stoke door 12, the ashes being removed from beneath the grate portion 6.0f the heating pipe, through an ash door 14 hinged't-o'the outer casing 8 of the furnace. supplied with suitable da1npers'15, of any Communicating with the fuel chamber 11,-is the stack 16'.

face of the furnace, transversely, communicates with an inlet pipe 17 and with an outlet pipe 18. These pipes '18 and 17 as will be understood, communicate with each other, o

so that there is acontinuous circulation through'the pipes 17 and 18, and through the ,coil wherewiththe furnace 1 is 'linedin its interior. In the drawings, for the purpose of economiz ing space, the pipes 17 and 18 have 'beenbroken away, but the continuous circulation above referred to, and af- The doors 12 and 1 1 may be forded by the pipes 17 and 18 and by the coil which'is within the furnace 1, will be readily understood. 1 I

' Interposed into the circulatory system, at any suitable point therein, is a tank 19' or the. like, whereby the circulatory system may be filled with the liquid which is to be heated. Interposed in the outlet pipe 18, is

.a'pump 20, the pump '20 being preferably,

of the rotary type, the pump being operatively connected with a prime mover, in the present instance, shown in the formof an electric motor 21.

The practical operation of the device is as follows. Through the opening closed by the door 12, peat or other, fuel may be introduced into the fuel chamber 11, the fuel resting upon thegrate portion 6 of the pipe coil, the fuel being stacked up, to any desired extent,'aga inst the side portions 9 of the pipe coil. lVhen the fuel which is with-- in the chamber 11 is ignited, it will be seen that the pipe coil will be heated to a high degree, raising the temperature of the liquid which is within the pipe coil. When the pump 20 is put into operation, the heated' the construction of the device is such that the furnace 1 maybe placed at a considerable distance from the building to be heated, the pump 20 serving to force the heating medium through the circulatory system. At this point it may be stated that the specific location of the pump 20 in the cir- 'culatory system, may be'varied to suit the V exigencies of the particular case. It is to be noted, moreover, that in Warm Weather,

the chamber 11 may be filled With ice, the a device operating, in the manner hereinbefore described, the pump 20, however, servingto cause a circulation of a cooling medium, in-

stead of a heating medium. Under such circumstances, the device acts as a refrigerating plant. W Vhen the structure is employed for refrigerating purposes, a suitable drain23 may be placed in the bottom of the furnace 1, to lead away the drip from the ice which is Within the furnace structure.

I-Iavin'gt-hus described the invention,what

is claimed is In a device of the class described, a furnace comprising inner and outer casings, separated, to define a dead air space between them; a centrally open frame securedto the inner casing;

trally open portion of theframe, to constitute the grate ofthe furnace, the pipe a sinuous pipe coil supported upon the frame and extended across the cen-' coil being continued in'sinuous form, along the sid-esof the furnace and-across the top of the furnace; a circulatory system of which the pipe coil constitutes a part; a pump in the circulatory system a motor for operating the pump; and an element in' the circulatory system, whereby the fluid to be heated,-may be introduced into said system.

In testimony that I claim theforegoing as my own, I have hereto affixed my signature in the presence of two? witnesses.
