LUMBER DRIER.

Application filed February 24, i923, Serial No. 620,961.

To all whom t may concern.'

Be it known that l, Koscon D. Srrins, aV

citizen of the United States, residing at Norfolk, in the corporation of the city of Norfolk and State of Virginia, have invented certain new and useful lmprovements in Lumber Driers, of which the following is a specification.

This invention relates to new and novel improvements in lumber drying apparatus, and is especially designed for the use of operators of porta-ble saw-mills, who at present have no means of properly curing their products except by the use of cuinbersome and expensive steam boilers and pipglhe prime object ofzthe invention is to provide a simple, durable, economical and efficient apparatus adapted for the purpose of properly drying and curing the products of portable saw mills.

Another object of this invention is to so construct the improved apparatus that the parts may be readily and easily disconnect ed, moved to a new location as desired and quickly reassembled.

A. further object of the invention 1s to provide means in connection with the apparatus, constituting` a sheet metal hood or protector, which efliciently serves the double purpose, namely, iirst, to deflect any chips, lint, dust, bark or other substances which would be likely to fall on the hot radiator pipes and cause contlagration, second, to more evenly diffuse the heat rising from the radiator and thus prevent the lumber' nearest above the pipes becoming cracked or checked from the intense heat radiated fromA the pipes.

The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, an rangement, location and combination of the several parts hereinafter more fully described, illustrated by the accompanying drawings, andparticularly set forth in the claims appended hereto, l it being' understood that slight changes in the proportions and minor details of the construction maybe.

resorted to without departing` from the spirit or sacricing any of the advantages of the invention.

iIn the accompanying drawings forming a part of this specication it will be seen that z- Figure l is a side elevation vof the apparatus embodying my invention, with the metal hood or protector removed.

Figure 2 represents a plan partly in section, taken in the plane of the dotted lines 2-2, Fig. l, looking in the direction of the arrows, with the hood or protector removed.

Figure 3 is a plan taken in the plane of the vdotted lines 3 3, Fig. l, showing the metal hood or protector in full lines and the heat radiating pipes in dotted lines, looking in' the direction of the arrows, and

Figure a is a cross-section taken in the plane of the dotted lines 1 -e, Fig. 3, locking in the direction of the arrows.

In the embodiment of my invention as illustrated, it will be seen that the numeral 5 designates the furnace, the brick wall of which is preferably about nine inches in thickness, 6 indicates the cast iron front of the furnace having rearwardly extended iianges 7 formed therewith at each side thereof, 8 the channel irons or plates, and 9 a plurality of threaded bolts which are passed through the brick work of the furnace from side to side, through said anges 7 and the channel irons or plates, the threaded end of each bolt being provided with a securing nut l0, whereby the said parts are iixedly secured, and thereby'fastening the furnace securely together. The numeral 1l indicates the cast iron furnace fuel feed door, l2 the ash cleanout and bottom draft door, and 13 the furnace damper formed of heavy sheet iron, with a rod lil extending entirely through the walls of the furnace and provided with a handle l5 at each end of said rod.

lt will be perceived that the inner or rear end 16 of the furnace which projects into the drying or curing house, is formed with an arch to it, which is designed to take care of the tar and other waste matter which formerly had a tendency to clog up the old form of furnace, hence by this particular formation the flame appears to completely burn and consume these lary-products, and for the same reason the furnace is dropped below the level of the drying or heat radiat ing pipes, the front of said furnace being approximately two feet Vbelow the grade, the numeral 17 designatingV the pit at the front of the furnace for the attendant or operator.

The drying or curing house 18 consists of any suitable light frame portable structure Whichumay be readily removed and reassembled, and its interior is provided with a plurality of upright iron columns 19, properly spaced apart, and adapted to fiXedly prises a Y-shaped member 22 at its front end', formed of heavy sheet iron with itsV outer end fittedinto the rear end ofthe furnace, each inner end of said member 22 being connected to one end of an outwardly and rearwardly inclined primary radiating pipe 23, the o'ther end of each of the pipes 23 being connected to one end of an elbow member 24, and the other end .of each elbow member is connected to one end of an inwardly and rearwardly inclined primary radiating pipe 25, the rear end of each pipe 25 being fitted to the inner ends of another Y-shaped member 26, the rear end of said member`26 being connected to the exhaust stack 27, formed of heavy sheet iron, suitably secured to the rear of the house, and provided with a damper 23, while the secondary radiator pipes 15 are fitted into cast iron collars 29,'securely1 riveted to theA pipes 23 and 25, with the squared ends of each `pipe 15 projecting into the pipes 23 and 25 in order to receive its proper proportion of heat, and the central radiator pipe 30 extends from and connects the Y-

shaped members

22 and 26, each end of said pipe 30 being passed through a castV iron collar 31, riveted to each Y-member, and projects into each

member

22 and 26, in order that this pipe 30 may receive only its proportion of heat, approximately onefourth. In each primary radiator pipe 23 and 25 near its forward end is fitted a suitable damper 32 by which the heat is controlled in the radiating system and shifted to either side of the system by the proper manipulation of these dampers. This entire heat radiating system is suitably supported upon a plurality of channel irons 33 which are fixedly secured in any desirable manner to the vertical iron columns 19.

vIt will be seen that each section of my improved heat radiating system comprising the

pipes

23, 25, 15 and the elbows 24'are so constructed and connected together as to be readily interchangeable.

As clearly shown in Fig. 3, it will be seen that my entire heat radiating system is provided with a sheet metal hood or protector v 34, which is liXedly secured to the beams 20,

and extends above and along the entire length of each radiator pipe, in sucha manner that the hood will be suspended. directly over, but not in contact with the radiator pipes. The said hood is formed by bending the metal sheets lengthwise, in the center, to an angle of ninety degrees and is rein- -forced or braced by having metal angle brackets 35 riveted to its lower sides. After being placed. in position the several pieces are bolted or riveted together, thus forming a continuous hood or tent like structurel over the entire set of radiator pipes. Each hood is six inches wider than the pipe it covers and the form, when placed in position, is like a gable roof house, with the eaves extending beyond thepipes on each side thereof.

It will be readily obvious that the metal hood or protector is adapted to perform a double function, that is, it not only serves to deflect any chips, lint, dust, bark or other substances which would be likely to fall in contact with the hot radiator pipes and thus cause a conflagration, but it also serves to more evenly diffuse the. heat risingT from the radiator and prevent the lumber nearest above the pipes from becomingA cracked or checked from the intense heat emanating from the heat radiating system of pipes.

It will also be evident that my construction of drier will readily permit the apparatus to be quickly disconnected, moved to a new location, and quickly reassembled, and that said apparatus is so constructed as to distribute the heat substantially over the entire area of the housethus constituting an efiicient means for the purpose intended.
