Pole kiln and method for drying logs

Claim 2

A drying kiln comprising: a. a shed covering one or more carriers of articles to be dried; b. end closures on said shed; c. means for introducing heat into said shed at a location above said articles; d. baffles that coact with said one or more carriers and prevent said heat from flowing beneath said carriers; and e. means for circulating said heat within said shed.

Claim 3

The invention of claim 1 including: a. baffles above said one or more carriers that prevent heat from passing upwardly from said articles therein.

Claim 4

The invention of claim 1 including: a. baffles disposed alternately on opposite sides of said carriers whereby said heat cannot pass through the space between adjacent carriers.

Claim 5

A drying kiln comprising: a. a shed covering one or more railroad cars fitted with braking equipment; b. end closures on said shed; c. means for introducing and circulating heat within said shed; d. baffles that coact with said one or more cars and that prevent said heat from flowing beneath said cars; e. baffles above said one or more cars that prevent said heat from passing upwardly from said cars; f. baffles disposed alternately on opposite sides of said cars so that heat cannot pass through the space between adjacent cars; g. means applicable to said braking equipment for cooling such equipment and preventing said heat from contacting the same; and h. means for detecting overheating of said braking equipment.

Claim 6

A drying kiln comprising: a. a shed covering one or more railroad cars fitted with braking equipment; b. end closures on said shed; c. means for introducing and circulating heat within said shed; d. baffles that coact with said one or more cars and that prevent said heat from flowing beneath said cars; e. baffles above said one or more cars that prevent said heat from passing upwardly from said cars; f. baffles disposed alternately on opposite sides of said cars so that heat cannot pass through the space between adjacent cars; g. means applicable to said braking equipment for cooling such equipment and preventing said heat from contacting the same; and h. means for detecting overheating of said braking equipment.

Claim 7

The invention of claim 1 including: a. means for pivoting said baffles.

Claim 8

The invention of claim 2 including: a. means for pivoting said baffles.

Claim 9

The invention of claim 3 including: a. means for adjusting said baffles; and b. means for pivoting said baffles.

Claim 10

The invention of claim 1 wherein: a. said means for introducing heat includes a burner and a fan.

Claim 11

A drying kiln comprising: a. a shed having pivotable enclosures covering one or more carriers of articles to be dried; b. a burner and a fan in conduit means carrying heated air to a heating duct in said shed above said one or more carriers, said duct having openings through which heat flows into said shed; c. pivotable baffles above said one or more carriers that prevent heat from passing upwardly therefrom; d. pivotable baffles that coact with the sides of said one or more carriers and prevent heat from passing therebeneath; e. pivotable and adjustable baffles disposed alternately on opposite sides of one or more carriers whereby heat cannot pass through the space at the ends of one carrier or between adjacent carriers and is directed lengthwise thereof; and f. one or more fans within said shed that circulate said heat therewithin.

Claim 12

A drying kiln comprising: a. a shed having pivotable enclosures covering one or more carriers of articles to be dried; b. a burner and a fan in conduit means carrying heated air to a heating duct in said shed above said one or more carriers, said duct having openings through which heat flows into said shed; c. pivotable baffles above said one or more carriers that prevent heat from passing upwardly therefrom; d. pivotable baffles that coact with the sides of said one or more carriers and prevent heat from passing therebeneath; e. pivotable and adjustable baffles disposed alternately on opposite sides of one or more carriers whereby heat cannot pass through the space at the ends of one carrier or between adjacent carriers and is directed lengthwise thereof; and f. one or more fans within said shed that circulate said heat therewithin.

Claim 13

The invention of claim 9 wherein: a. said one or more carriers is or are railroad cars having braking mechanism; and including b. means applicable to said braking equipment for cooling and preventing heat from contacting the same; and c. means for detecting over heating of said braking equipment.

Claim 14

The invention of claim 9 wherein: a. said baffles are sectionalized.

Claim 17

The invention of claim 12 including the step of: a. maintaining the flow of heated air lengthwise of said poles in each one of said railroad cars.

Claim 18

The invention of claim 12 including the step of: a. cooling a braking mechanism of said one or more railroad cars.

Claim 19

The method of claim 12 including the steps of: a. arranging baffles that prevent said heated air from flowing under said one or more cars; b. arranging baffles that prevent said heated air from flowing upwardly from said poles; and c. arranging baffles that guide said heated air lengthwise of one such railroad car and that prevent said heated air from passing through the space between adjacent railroad cars without having first passed longitudinally of said adjacent cars.

Claim 20

The invention of claim 4 including: a. means for adjusting and b. means for pivoting said baffles that are disposed alternately.
