Nov. 9, 1943- c. B. MALARKEY 1 DOOR CONSTRUCTION Filed Feb. 1 1942 mQ v j I19. 3 Tlg' cHARLEgveMAAaKEY ATTORNEY Patented Nov. 9, 1943 2 Claims.
This invention relates to doors, and has particular reference to a door so constructed as to resist the stresses which tend to warp the door out of a fiat plane.
Doors are commonly constructed of stiles, rails and panels. The stiles and rails comprise the framework of the door, the stiles being the mem- I bers which define the longitudinal edges of the door, and the rails being the cross members which unite the stiles at the top and bottom edges of the door and at intermediate points,.de-
pending upon the type of construction. "The panels occupy the spaces between the stiles and rails. In the lmanufacturing process, the stiles an railsare sawed and planed, to the proper dimen; sions and delivered to the assemblyroomto await the operations of the workmen who fabricate the 'doors. After lumber is sawed it becomes subject to new stresses which tend to warp each piece out of the flat plane created bythe saws...v It
will be appreciated that woodis not a solid homo geneous substance like: steel or glass. It is ,made up of innumerable little hollow tubes called fibers,
arranged lengthwise or along the grain in the wood. Wood fibers are 'addedeach year as the tree grows, and the size and number of the fibers added 'in each year's growth ring depend upon the amount of moisture, sunlight, andother plant food available to the tree during the par- 7 ticular year of growth. Consequently, no two pieces of lumber are exactly alike, nor is'the fiber structure on one surface of a board exactly like the fiber structure on the other surface. For
this reasonyas moisture is absorbed by the wood fibers, the piece of lumber tends to bend into the shape which will best accommodate the'moisture 7 Charles Malarkey, Portland, Oreg. Application February 16, 1942, SerialNo. 431,094 1 absorption by 'thefiber structure adjacent its respective surfaces. For this reason, in the manufacture of doors, for example, wherein the fiatness'of the dooriswholly dependent upon the ability to retain the structural members in a fiat plane, a great deal of difiiculty isexperienced due to the tendency of these members to assume a warped shape. l
In the assembly roomof the door manufactuv ing plant, only those longitudinal structural members which have remained absolutely'straight are used in the'fabrication of-lthe doors.- The great number of these members which have become warped arenecessarily' discarded. These are of clear stock, that is, free from knots, pitch seams, and the like, and represent a serious loss to the manufacturer; It has been discovered that these warped structuralmembers can be utilized invention.
for the purpose for which they were intended by cutting them intoshorter lengths than the length of the door, and thereafter uniting in end 10 end.
relation the requisite numberof pieces of door stock cut from unrelated timbers to make a stile of the requiredlength. Itis preferable that adjacentsections of the composite stile comprise a fiber structure which varies greatly in each section. In such a structure the tendencyof each individual section to bend into :a shape is counteracted by the tendencyof adjacent sections to assume a difierent shape dfue to the stiilening influence of panel sections which engage the inner edges o fadjacentsections. "Thisjco'nstruction is particularly productive "of the efiect intended if the several pieces are united withthe longitudinal curvature of the grain in adjacent pieces disposed toward opposite faces of the stile. 1 In other words, adjacent sections whichrnay be cut from a single stile are facedinthe opposite direction from their original ;p osition, whereby. the longitudinal center of the composite stileiabricated therefrom, instead of being' warped in a long continuous curve from end. to end of thestile, is caused to follow a' number. of ,pieces ineach of whichthe curvature is disposedtoward opposite faces or the stile Thereupon, the composite stile is run through the planer to, produce the desired fiat surface and a structure is had wherein the tendency to warp out of a flat plane is materially lessened.
t is the primary object time invention to i provide a door construction wherein the forces .which tend to cause the door tobendin onedi- 1rectionare resistedby forces. which tend to cause thedoor to bend in theopposite direction, thereby tending to hold thedo'or in a flat plane.
' A further object of the invention is to provide means for utilizingdoor stock which has become 'warpe'dout. of a fiat planefor the construction o'fdoors which are notably warp resistant.
With these andother objects and advantages in view, the inventionlresides in the novel construction hereinafter described [and illustrated inth'e accompanying drawing, it being under stood that various modifications of size, proportion and detail of structural featuresmay be .em-,
ployed without departing, from the scope of the Referring to the drawing, Figure l a perspective View of a portion of a. door embodying the present invention; Figure: is an edge view -of'the door illustrated in Figurel; Figure 3.is;a

The drawing illustrates a door construction wherein the longitudinal structural members or stiles have been cut into a plurality of pieces of a length considerably shorter than the requisite length of the stile. Referringto Figures 1 and 2, the door stile illustrated comprises sections l, 2 and 3 which have been joined in end to end.
relation by tongue and groove joints 4 to produce a composite stile of substantially uniform dimensions throughout its length. Infabricating the longitudinal structural member 'or stile; the pieces I Z and 3 are selected ;to present in adjacent sections of the stile a fiber structure of greatly variant characteristics.
These are so arrangedthat the longitudinal curvature of the grainin adjacent pieces isdisposed toward opposite {aces :o fthestile; In the construction -illustrated, the longitudinalcurvatures of pieces .-l;.and 3 are disposed in the direction of arrows 5 and. 6,- while thelOngitudinaljcurvatHre of piece 2 isdisposed in the direction of the arrowl. In this structure the forces, tending. to .warp the door in either one of the directions indicated by the arrows .aretransmittedby the adjacent panel section to=the adjacent stile section. and thereby oppose .the forces tending to warp the door in theopposite. direction, with the result thatthestileisheld in a substantially ,flat {plane irrespective of I conditions vaiifecting. the ..moisture content of the wood. The, door illustrated in v the drawingJcomprises rails 8, Sand l0,.the' first and lastmentioned frails constituting. the. top. and. bottom .edges of" the do'orgfres'pectively, while. rail 9 divides .the. space. bounded. by; the stiles and. rails 8. and .l9.-.into.panel sections H and; 1 2.

Thus, it will be seen that in the instant-structure each panel engages the inner edges of .adfjacent stile sections and tends to hold them ,in a
straight line.
The construction is productive of a door em;
