' Application med November so, 1925. semi No. 72,186.; i

This; invention relates to heaters "for rooms, compartments, tents, and the like, the object'being to construct a heater to burn sawdust, shavings, and other waste r; combustible matter, which requires no at-'. tentionafter a' fire is started, and which vey them to a suitable outlet to beI1c'on-' nected to a fine or chimney.

in the provision of core bodieswhich'are arranged before the sawdust is introduced into the inner or combustion cylinder to form draft channels or passages for the free .to enhancethe operation of the heaterand incite combustion.

I have illustrated a preferred embodiment of myjinvention in the accompanying drawings in which v y Fig. 1 is a central sectional elevation of my improved heater showing thecore bodies in position to form; air channels after the sawdust has been tamped and said cores reinoved; a a H I V Fig. 2 is a partial section of the heater with the cores removed and the sawdust charge ready for igniting.

3.3 of Fig. 2.

'Fig. 1 is a fragmentary vertical cross section on the line t-et of Fig. 2. V V Fig. 5 is a detail perspective showing a channeled molded sawdust block which may be used as fuel for my heater.

Referring to the drawings, 10 and 11 are the outer and inner spaced cylinders or drums forming the body of my improved heater, the latter being removable, and providing a circumferentialrspace or smoke chamber 12 toreceive and direct the products of combustion to, the flue or 'chi'mney13.

The outer cylinder or drum 10 is formed 5 with a bottom 14, shaped to provide a cross sectional semi-circular trough 15,.an'd the in ner cylinder or drum 11 is formed with an Dutwardly directed short cross sectional A further feature of the invention resides circulation of the air through the sawdust liquor) Fig. 3 is a horizontal 860131011 on the line semicircular extension 16 to register with the outer end portion of trough 15, and tog ether form1a short air tube 17 across the I smokecliamber 12.; This tube is normally:

open but maybe partially closedwhen the heateris operating to regulatethe inflow of airv by afdamper 01' valve plate 18,-slidable.

in guides, 19,. which frictionally hold the va-lve'plate on any elevation.

The heater may be closed at the top when I in operation by a cover 20 resting on the outer cylinder or drum 10, somewhat above the upper end of the inner cylinder or shell 11 to provide free passage for the said prodor chimney.

The heater may be provided with feet or rests'21 to space it from the floor.

To properly place the removable innerv cylinder 11 so that the sections of the air nets of combustion on their way to the flue with radial lugs122, one ormore engaging r sockets 23. on the bottom 14 of the outer one, to preventa relative turning movement of the cylinders.

, In Fig. 5 of the drawing, I have shown a cast or molded sawdust disk or block25 having air channels for passages 26 and disks of this character may be used as fuel in my heater in lieu of loose sawdust. The disks may be prepared by using the Waste liquorof paper pulp manufacture (sulphite dust.

WVhen recharging the heater prior to starting a newfire, I pass a core 27 through starcheto, as a binder for the saw- I the air tube 17 and, into and alongthe q trough 15 tojabout the center of the cylinder ll', after which I place anothervertically and centrally arranged core 28 in the said cylinder. Thesawdust isthen introduced and packed or tamped around the core 28 until the combustion chamber 29 is filled, after which the cores are removed,

leaving air channels 30 and 31,-and a match or tor-ch is then applied to the charge through air tube 17 after the cover 20 is said cylinder vmaybe lifted out of'the outside cylinder 10 and the. possible ashesv removed. In this case air shaft 17 is placed entirely above the bottom of cylinder 11.

What I claim as new, is 1. A heater comprising spaced cylinders,

one having a bottom formed with a crosssectional, semi-circular trough, the other being open ended and provided with a crossscctional semi-circular extension adapted to register with the trough and together form an air inlet tube spanning the space between said cylinders, thereby forming an air passage to the firing charge.

2. In a heater, an outer cylinder provided with a bottom having a cross-sectional, semi-circular trough, an inner cylinder having spacing lugs and a crosssectional, semi-circular extension to register with said trough to form an air tube spanning the space between said cylinders thereby forming an air passage to the firing charge, said outer cylinder having sockets to receive said spacing lugs to lock the parts against relative movement.

3. In a heater, an outer drum having a removable cover, an outlet flue and a bottom formed with a cross-sectional semi-circular trough, an inner drum having semicircular extension registering with said trough to collectively form an air inlet tube spanning the space between the drums thereby forming an air passage to the firing charge, and a valve to control the passage of air into said tube, as described.

Signed at New York city in the county and State of New York this 18th day of November A. D. 1925.
