`J ESSE B. JOHNSON AND THOMAS E. JOHNSON, OF INDIANAPOLIS, INDIANA.
Letters Patent No. 97,777, dated December 14,`l869.
Lumen-Damn The Schedule referred to in these Letture Patent and making part of the same nace used in `the.drier; patented by J esse B. Johnson,
March 1i), 1868, numbered 7 5,27 7, and-a drying-chainber, tiunished with defiectors, and trucks for holding the lumber, and Ventiducts, arranged in such a manner as to more uniformly distribute the heated air throughout the dryingfchamber, especially near the hmr, andmthus to avoid the imessity of handling the lumber, or changing its position, in order to dry it l uniformly at bottom and top.
Description. of the Accompany-ing Drawings.
`ligure'1 1s a vertical longitudinal section of a drying-kiln embodying our invention.
Figure 2 is a transverse section of the same.
General. Description.
A are the walls ot' the drying-chamber, which may' be built of any suitable material, and in any suitable manner.
rlhe furnace B, the top -ofwhich is covered with cobble-stones or other analogous material, substantially in the 'manner described in the Letters Patent, No. 75,277, issued to Jesse B. Johnson, March 10, 1868, is situated at one end, and across the dryingchamber, as shown.
This furnace may be connected with a chimney or ue, as mentioned in the Letters Pat-ent already referred to, for the purpose therein described.
A curved detlecting-plate, C, is arranged over the furnace B, hung on a rod extending through the side of the drying-chamber, and furnished with a lever on the outside, by which the detlecting-plate may be raised and'lowered at pleasure, and thus be made to subserve a double purpose, viz;
First, tocover the top-0f the furnace in starting the fire, causing all the products of combustion to pass oti'tbrough the flue; and A Second, to be turned up at such an angle, as shown in iig. 1, as to give a horizontal direction to the heated air and products of combustion as they rise through the. boulders into the lower part of the lumber.
D are vertical deiecting-piates, made of metal or other suitable material, hung to the sides of the building, and held by springs, or otherwise, in such manner as to rest against the lumber on the sides, for the purpose of directing the currents of heated air into and among it; and
' E are horizontal a similar purpose, hung to the ceiling of the dryingchamber.
The trucks or cars upon which 'the lumber is piled,
,for convenience of running it into and out ofthe drying-chamber, are made with` longitudinal stripsH,
resti'tig on lthe top ofthe truck-frames upon which the.
lumber is piled.
The spaces between the pieces H form tiu'es for the passage of the heated air and products of 'combustion beneath the lumber, and then, together with the side and top deflectingl-plates D and E, and the openings into the iue G, situatedv near the tioor of the dryingchamber, will, to a great extent,overcome lthe` Vteudeney ot' the heated air to rse,and thus cause a more equal distribution of it low down in the drying-chamber, and hence will' dry. the lumber more uniformly throughout the kiln.
Gr are-ventiducts, builtin any approved manner, and situated at the end of the drying-chamber, opposite the furnace, for thel'eseape of thc air after it has ciroulatediamong the lumber. The openings into these lues are situated near the iioor of the drying-chamber.
