2 crains. (or. 1.24535) An object of my invention is to provide adoor structure invwhich there i's a plank type door having a smooth face (or one 'with VV grooves in it if desired) Without any sunken panels or the r. like so that the door has the appearance of being.

made entirely of similar boards or planks.V

A' furtherobject isv 15o-provide a suitable rein-l forcing frame for the 'door 'and' a practical method Vfor securing thev frame together and for l! also securing the'fa'cin'g boards to the frame in such av wayrthat theappearance of the door, asfalreadyireferredto, willnot be altered by theassernbl-y ofthe `frame and facing boards. f A' further object is to provide a door structure '115; that offers Vmaximum resi'stanceagainst the en trance of rain and is devoid` of grooves or pockets intowhich water may enter `and start decay.

A further 'object of my present invention is to provide a means for holding or locking the facing boards and framework securely together without the useof screws, nails or the like. j A further object ijs to provide ina door having dowelor tenori 'andmortise joints, la means to prever-'1t entrance of Waterto these joints, thus- Y avoiding decay in them.`

lllnother'oln'ect` isl toprovide a door structure that is pleasing in design and that is rigid and lasting.i Y

Another lol'zject is to provide-a' form of construction inwhich lonlyvorne facing board is used between the stilesv of the door` frame whereby to provide a door having the appearance of Vertical stiles and a panel.

A :further object is to provide a door construction in which the single facing board may be glued or otherwise secured to the rails of the door instead of providing dovetailed rib and dado joints.

Another object is to provide still another modir ed form of door construction in which a single facing board or panel is applied to each side of the Ydoor whereby the sides appear similar and the rails of the door frame are concealed between the facing boards.

With these and other objects in View my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims andV illustrated in the accompanying drawings. tion is susceptible of a variety of embodiments, it is unnecessary to fully describe and illustrate more than one in order to give a full understanding of the invention both from its structural and Although the inven- - boards 18, 20 and 22 Which I Will functional standpoints. Accordingly, I have vi1- lustrateda preferred and desirable embodiment of the invention in the accompanying drawings nwhichzgi. i

The door'A commises a plsuraliisg of members 16, 18, and 22 which have similar appearing faces as will be obvious from inspection of Figure 1. The members 18 and 20 are actually similar with the exception of their lengths as is obl vious from Figure 4.

The members 20 and 22 are shortened to form an opening 24 in which a window B may be set. 9i The window B consists of a sill 26, side jambs 28, head jamb 30 and pane of glass 32. The construction of the window B is fully disclosed in my co-pending application, Serial No. 444,190, lled April 14, 1930.

Although the faces appear similar, the members 16 and 18 are of different relative thicknesses as best disclosed in Figure 2 of the drawings. The members 16, which I have termed as stiles, are somewhat thicker in order to act as part of a framework for the door structure and project backwardly with respect to the inner faces of the term facing boards, but are ush on their outer faces.

'I'he facing boards 18, 20 and 22 are connected 1%10 together at their edges by grooves 21 and tongues 23. The right hand stile 16 also has a groove 21 for a tongue 23 of one of the facing boards 18. A spline 25 may be used for connecting the left hand stile 16 with the adjacent facing board 18 as shown in Figure 2.

In conjunction with the stiles 16, rails 34, 36 and 38 are utilized for completing a rigid framework for the door A. As best shown in Figure 3, the rails 34, 36 and 38 are provided with dovetailed tongues 40 which fit in transverse dovetailed dadoes 42 formed in the rear or inner faces of the facing boards 18, 20 and 22. The lrelative positions of the rails 34, 36 and 38 are shownby dotted lines in Figure 1 of thedrawin'gs. ,i

The ends of the rails 34, 36 and 3 8 may be connected with the inner edges of the stiles 16 rwhich project back of the inner faces of the facing boards 16, 18 and 22 by means of dowels48, forl instance, which fit in dowel openings 44 and 46.in the stiles '1G-.and the rails 34, 36 and 38 respectively; This construction is best shown in Figures 2 'and 4 of the drawings and other suitable fastening arrangements can be SubStitutedsuCh, for instance, as mortise and tenon joints,A not shown. In order to t the dovetailed tongues 40 tightly in the dovetailed dadoes 42, the rails 34, 36 and 38v after being machined are preferably dried to'causerthem'to shrink whereupon the facing boards 18, 20 and 22 are threaded on the dovetailed tongues so that ywhen the rails'again absorb a normal amount of moisture,. they will swell and tightly flt within the dadoes 42;

After the ends of the rails are secured to the stiles 16 by means of dowels, tenons or the like, the-door `is completely assembled and gives the appearance of the entire face being made of similar boards andyet arigid framework is provided forthe door construction withoutvisible fastening'means on the face of the door for securing the facing boards to the frame consisting of the members 16,34, 36 and 38.

In Figures 5, v6 and 'l I have shown a modified form vof constructionin which a single-,facing board'50 is used instead of a plurality of -facing boards as shown in Figure 1. The facing'board 50 maybe made of 'laminated Wood/ usually provided for panels and may be merely glued ory otherwise secured to the rails 34, 36 and 38 instead of having a dovetailed rib and dado connection therewith.

Instead of havingy a tongueand groove connection with the stiles 16,'the edges of the facing types of doors and without board or panel 50 may be beveled to coact with beveled or dovetailed grooves 52 formed along the inner edges of the stiles 16. The thickness of the rails and panel together is equal to the thickness of the stiles 16 so that the outer faces of the stiles and panel are flush and the inner faces of the rails and stiles are also flush.

As shown in Figure 8, asecond panel 5'4 may be provided on the inner side of the door A so that both sides of the door appear identical and in such a construction either the rails are made thinner or the stiles aremade thicker than in -Figure 6 so that the aggregate thickness of the two panels 50 andI 54 and the rails is equal to the thicknessrof the stiles. f

' The stiles and one or more facing boards all present arush face appearance for making an attractive door. without sunken panels as in many the consequent evil of horizontal groove connections into which water mayrun and cause decay.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my'invention, and itis my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably includedv within their scope.

fclaim as my invention:

1.V A door structure comprising rails, stiles and facing boards, said rails being thinner than said stiles and having longitudinal dovetailed ribs, lsaid facing boards having dovetailed transverse dadoes to fit said ribs, said stiles and facing boards being assembled in substantial flush face relationship and the combined thickness of said rails and said facing vboards being substantially equal to the thickness of said stiles when they -are all in assembled position.

2. A door structure comprising rail members, stile members and facing boards, one of said members being thinner than the other of said members and having longitudinal dovetailed ribs, said facing boards having dovetailed transverse dadoes to t said ribs, said other members and said facing boards being assembled in substantially flush relationship and the combined thickness of said first mentioned members and said facing boards being substantially equal to the thickness of said other members when they are all in assembled position.
