Specitlcation of Lettersllatent,
l Patented Sept. 17, 1912; 1, 1911. serial No. 658,023.v
To all whom .it may concern:
Be it known thatv I', Ronn'n ABnRNE'rrir,
- citizen of the *Dominionfofi Canada, resid?v ing at Port Moody, -in the Provincev of British; Columbia Canada,v have invented a new and useful owing-Kiln, of which the. following is va specification.A i '1 f1 This invention relates to a kiln for drying lumber or shingles and belongs to that class wherein heated air is circulated through a, chamber in which the material to be dried is stacked.
In kilns of this description, after the air within the kiln has become laden with mois? ture, its drying'eiiiciency is considerably impaired; yet if this .moisture laden air is withdrawn or permitted Ato escape and fresh air is substituted., a considerable amount of heat is wasted,
The object of this invention is to conduct the moisture laden air in the course of its circulation to where it will come in'contact with va condensing surface on which the moisture will deposit', and the air, after the moisture has been abstracted from it, is'reheated and again passed through the drying chamber. The particular construction by whichthis object may be attained in a simple and convenient manner is fully set forth in the following specification and-illus trated in the drawings by which itis accompanied, in which: y l
Figure 1 is a cross` section through the kiln. Fig. 2` is a horizontal section. to van enlarged scale of the double wall of the kiln, and-Fig. 3, a vertical section of the same.
In these drawings, which. illustrate the eX- perimental installation, 2 represents the drying chamber, which is heated by steam pipes 3 extending lengthwise along the middle of the chamber. The tracks 4 on which the trucks carrying the lumber to be dried are'mi ru'n into the chamber are supported on crossy tis 5 at a suiiicient distance -abovethe heating pipes to afford the heatedair ample room to distribute itself through the lum-l 'befa The side Walls of the chamber have an inner lining 6 of double shiplap with tar paper between secured on the studding an this inner lining 6 is carried up to the roof joists 9 from a similar double boarded-Hoor ,8, Vyvhich extends'lengthwse of the chamber f'roin the lining 6 to the steam pipes 3. AQ
lging. 10.of-douh1e1boards with tar paper, lwhich 1s carrledi from the bottom. for a .edge of which casing a downwardly angled sheddingl .late 1l is secured. 'lhisplate. 1L ,prefiera ly of thin sheet metal and pro? .jectsasuiiicient distance beyond the wall l0 to deliver water -clear .of it. Above' this walls is of corrugated sheet metal, as at 12, which 1s carried upto the cornice of the roof. The roof is preferably of low pitch secured directly uponthe roof joists 9 and may be coveredfwith any suitable weathering that is airtight. A passage 7 is thus left connecting the upper side of the chamber passing down the walls and under the flooring 8, with the middle space of the chamber wherein are the heating pipes 3. E .The moisture laden' hot air rising through the lumber stacked in the chamber 2 will by convection be carried down the'passage 7 within the walls and in the upper part of that passage will be brought in-contact with the outer casing 12 of corrugated metal, which cooler than the air within the drying chamber `and on. which therefore the surplus moisture in that Iair will condense. The water of condensation will run down the cor-4 rugated plate 12 and will be delivered out side the building by the shedding plate 1l, 'While the air fromtwhich this moisture has been abstracted will'bev delivered under the ioor 8 to the mid space wherein are the fore passing upward again through the drying chamber 2.
cfa/kiln to. meet the requirements of this stood that the invention is not comprised in the specific structure Vof the building. but vin the 'provision of a condensing surface past which the hot vapors rising .from the material beingdried are conveyed and in the prdvision for conveying the water of condensation to without the building.-
In its improved form the building may be made of concrete or of avcombination of concrete and wood or concrete and metal invention. y
Having now particularly described my invention and the manner of its use, hereishort distanceup the studding on` the upperv shedding plate 11 the outer casing of the Y being exposed to the external air will be 4heating pipes 3 to be reheated by them be- This constitutes the general construction.
invention but it must be distinctlyunderwithout departingfrom the spirit of this mounted in the space between the upper and lower outer Wall sections to receive the water 15 of condensation from said corrugated lslliathing and deliver it to the outside of the In testimonywhereof I have signed my name to this specification in the presence 20 of two subscribing witnesses. p 'ROBERT ABERNETHY.
