HORACE J. MORTON, OF CHICAGO, ILLINOIS.

LUMBER-DRIER.

SPECIFICATION forming part of Letters Patent No. 597,543, dated January 18, 1898. Application filed October 2l, 1896. Serial No. 609,633. (No model.)

To all whom it may concern:

Be it known that I, HORACE J. MORTON, a

resident of Chicago, in thecounty of Cook and is particularly an improvement upon those set out, described, illustrated, and claimed in Letters Patent of the United States granted to me on the 226. day of October, 1895, numbered 548,445.

The object of this invention is to obtain an improved construction of the inlet and outlet air passage ways, respectively, in a lumber-drier of the kind or class describedthat is to say, to obtain a construction which will he more durable than the constructions heretofore used, more cheaply made, and which will afiord better facilities for controlling the ingress and egress of air to and from the lumber-drier.

In the drawings accompanying and form'- in g a part of this specification, Figure 1 is a vertical sectional View of a lumber-drier havin g my inventionembodied therein; and Fig. 2, a perspective view of the central part of a portion of the top androof of such lumberdrier, showing the several constructions particularly embodying the invention.

A reference-letter applied to a given part is used to designate such part throughout both figures of the drawings wherever the same appears.

A is the floor of the lumber-drier, and a the false floor thereof.

A A are the outer side walls of the lumberdrier, and a a are the inner side walls thereof. The studding B B of the lumber-drier being placed between such side walls A a vertical passage-ways are thereby formed. The false floor a preferably extends from the inner side walls a a, respectively,toward the center of the lumber-drier and to underneath the steam heating coils or pipes F F.

B B are the studding of the side walls of the lumber drier, and b b are pieces of studding laid on the floor A, on which pieces of studding the false floor a is laid.

G O are openings through the inner walls o a, through which the heated and moistureladen air can pass from the lumber-drier into the passage-ways d d when covers D are removed from thereover.

C O are the discharge-openings from the lateral passage-ways (1 61 such lateral passage-ways communicating with the vertical passage-ways (2 respectively.

E E are standards supporting the longitudinally-extending stringers e e and also supporting the cross-pieces E E, on which the steam heating pipes or coils F F are placed.

A is the roof of the drier ,and a is a sheathing thereunder, such roof and sheathing be ing secured to the rafters B B C C are openings in planks A A, respectively, through which openings moisture laden air contained in longitudinally-extending passage-way O is discharged therefrom. More than one plank A is necessary to ohtain the length required for the passage-Way C", and such planks are not connected together. Each of such planks can therefore be moved separately to register the openings G C, and the number of such openings which areregistered by the moving of any given plank A depends upon the length of the plank, which is usually an ordinary sixteenfoot plank having eight (8) openings C therein.

a a are the plankings forming the sides of the longit-udinally-extending passage-way C, such plankings being secured to the vertical studdings a a and such longitudinally-extending passage-way G being divided by the studdings a a into compartments which are open at the bottom to admit moisture-laden 'air from the lumber-drier and at the top (when the plank A, forming a cover, is in proper relation to plank A forming the top or ceiling of such )assa e-wa Y C so that the a ertures Passage-ways D D communicate, respectively, with vertical passage-ways d d Pas- I sage-ways D D are formed by the planks a a hereinbefore referred to as forming the walls of the longitudinally-extending chamrber C, the posts D D rafters E 13 and plank D The posts D D extend above the movable plank A and D is a plank resting I on the top of such posts, such plank D extending longitudinally the entire length of the lumber-drier. V r

D D' are the covers to apertures O O in the inner side walls a a.

Y Y is a pile of lumber in position for dry:

, Y, and so much ofisuch moisture-laden air as enters compartments of longitudinz-tlly-extending chamber C which have openings 0 0 open will pass from the lumber-drier through such openings. Other portions of such moisture-laden air will pass through the openings 0 C,which have the covers D D thereof open, and willbecome mixedwith the fresh air passing downward in passage-ways d d (into which passage-ways the apertures O 6 open,)

and passing along with such air are discharged from the lateral passage-ways d (i through openings or discharge ends O 0 into the drier underneath the pipes or coils F F, to be thereby heated and forced upward through the ln m? her-drier and the contents thereof. The admission of air into the passage-Ways D D and passing thence through passage-ways D D (Z 61 and d d and discharged therefrom into the drier is controlled by those of the openings 0 O which are opened by the proper relative position of planks A A as when a certain pressure of air and vapor obtains in the drier no more air will pass into the drier until some of the discharge-openings O C in planks A A are made to register and so opened. When some of the planks A A are brought into proper relative position to reg ister the openings 0 0 fresh air will enter several of the adjacent passage-ways D D, so that fresh air is supplied to the drier along the length thereof through those of the passage-ways D D corresponding in position longitudinally with those of the openings C C which are registered by longitudinal adj ustment of plank A on plank A respectively.

In the use of the lumber-drier it will at times be found necessary to have the openings C C at one end of such lumber-drier entirely open, those at the other end entirely closed, and the intervening ones partly open and partly closed, such openings being from time to time changed to suit the varying kinds and conditions of the lumber being dried.

I do not deem it necessary to have the apertures O 0 opened ordinarily, and at no time is the opening thereof to equal in volume of delivery the capacity of the several passageways I), D 01 and d Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a lumber-drier receiving and discharging air through the roof thereof, and having laterally-extending air passage-ways under the roof, studding extending along the 'middle line of the roof and resting on the rafters of the drier, parallel, longitudinallyextending perpendicular walls forming in combination with the studding and rafters a series of airdiseharge compartments, a top having openings therethrough, to such airdischarge compartments,longitudinally-movable Planks, resting on such top, openings through such planks which may be registered with the openings through the top of the compartments by sliding the plank, additional studding resting on the rafters and against the longitudinallyextending walls of the airdischarge compartments, and additional perpendicular walls secured to the last-named studding, whereby a series of air-outlets are obtained extending longitudinally along the middle line of the roof of the drier and a series of air-inlets discharging into the later-' ally-extending air passage-ways are obtained adjacent to and on each side of the air-outlets; substantially as described.

2. In a lumber-drier, the combination of rafters extending laterally across the lumberdrier, studding on the rafters midway thereof, planking secured to such studding and extending down between the rafters, forming a series of air-discharge chambers, a top with openings therethrough to such series of airdischarge chambers, a movable board having openings therein corresponding with the open ings through the top of such air-discharge chambers, lateral passage-ways between the roof and the sheathing under therafters, on each side of the air-discharge chambers, additional studding on the rafters and against the planking of the first-named studding and extending above such planking, planking secured to the additional studding, forming series of air-inlets communicating with the lateral air passage-ways, means for conducting the air from such lateral air passageways into the lumber drier underneath the heatingpipes thereof, and a roof resting on the outside series of studding above the openings from the discharge-chambers, forming a longitudinally-extending chamber discharging its contents between the outer series of stud cling; substantially as described.
