ADAM CANT, OF GALT, CANADA,.ASSIGNOR TO I-IIMSELF AND HUGH CANT,'OF THE SAME PLACE.

Letters Patent No. 86,362, dated February 2, 1869.

To all whom it ma/y concern Be it known that I, ADAM CANT, of Galt,Dominion of Canada, have invented a new and improved Air- Heater; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilledin the art to make and use the same, reference being ba' to the accompanying drawings, forming part of this specication.

This invention relates to an improved arrangement for heating air, for warming buildings, or other purposes; and

It consists in the arrangement of the dues and plates Within the casing, as will be hereinafter more fully described.

Figure l represents a vertical section of the heater, through the line :t x of fig. 2.

Figure 2 represents vertical sections of iig. l, through the lines y y and z z, showing the arrangement of the airues, and the spaces between them, for the passage of the dame and products of combustion.

Similar letters of reference indicate corresponding parts.

This heater is placed over a suitable furnace or fireboX, and the flame and products of combustion enter through the aperture marked A, and circulate through the heater between tbeainllues, or through the spaces and passages marked B.

C is a horizontal plate, which forms the bottom ofl the air-dues, against which the tlame irnpinges as it enters the heater.

The course ofthe llame and products of combustion through the heater to the chimney is indicated by ar rows in red color.

D represents the chimney.

The cold air enters the heater through the aperture E, and passes through the air-dues, which are mal ked F, in an opposite direction from the llame or products of combustion, as indicated by the black arrows.

`and which allow of the removal of the Hue-section, or

theplates of which Aitis composed.

To regulate the flow of air through the heater, there is a damper er sliding plate, L, which is operated by the knob "m, which plays in a slot, a, in the outside casing.

By this arrangement it will be seen that a very great heat-radiating surface is exposed, and that the products of combustion must be compelled to part with their caloric before being discharged into the chimney.

Whenever fuel .is auobject, the advantages of this heater must be obvious to all.

I am aware of the patent granted Ato W. Duryea and W. Ennis, April 30, 1867, for an air-heater; but this contains no part of my invention, and I therefore claim nothing therein shown.

I claim as new, and desirev `to secure by Letters Patent- Ihe described arrangement, within the case H, of the horizontal air-dues F, the horizontal and end passages B, the horizontal partitions I J J', the plate L, and the plate G, all directing the air and the heated productsof combustion in the herein-described courses,

ADAM oAN'r.

' for the purpose specified.
