derstood from adetail description of the improved door.

With the foregoing object outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accomthe door.

Referring to the drawings, 4 designates the central panel, 4a the top rail, 4b one of the side stiles, 5 the mitred insert frame, and 6 the insert molding of the improved door. lt will of course be understood that the panel l is of rectangular form, surrounded by the rectangular frame 5, and that the latter is bordered by the rectangular frameformed by the side stiles and cross rails.

The panel 4 may be solid or veneered, and the rails and Stiles may be solid or veneered. The drawings illustrate the panel and one of the rails as veneered. The frame v5 also may be either solid or made fromveneered material, but it is illustrated as solid.

Doors of this type in the past have been made in various lways. The molding 6 in the most common method has been nailed at the points marked A, to the insert frame 5, and as the molding is thin, it is necessaryr to place the nails rather close together, and the molding at the edges B is apt to move away from the insert frame, and leave a slight space between the molding and said frame.' Such a construction is not only objectionable for l this reason, but the numerous nail holes at the points A, require puttying before the door is either painted or varnished. In the varnished door, the nail holes always show as aH disgurement. l

In accordance with the present invention, it will be noticed that the insert frame is under-cut along the lines C, at opposite sides of the frame to provide substantially V-l 50 shaped projecting tongues C. The molding 6 is under-cut on one edge to fit the undercut` on the frame 5, in such a way as to form lips 7 which overlap the tongues C. The lip is a rather important feature, in that it cov-@ ers any unevenness in the sharp corners of the tongues. The molding, in practice, is nailed from the outer edge, as shown at 8, and these nails of course extend into the insert frame. Owing to the improved con* struction, the nails are spaced' widely apart, as they are only used to hold the molding irmly in position before the panel l is assembled in the stiles and rails. It is not necessary to have as many nails as used heretofore;V z and the nails are all concealed, as their heads are covered b v the stile and rail members.l

It will be observed that the opposite faces of the frame 5 are so cut as to leave spaces 9 between the frame and the molding. Suchf/go spaces allow slight variations in the shape of the molding, and permit perfect joints of the molding with the insert frame, which of course, is very desirable.

The Stiles and rails are under-cut along the lines 10 to receive the step-shaped outer edges of the molding, so that the molding enters the stiles and rails for a short distance.

Tongues 11 project from the edges of the insert frame, and they enter correspondingv grooves lla in the stiles and crossV rails, whereby whenfthe latter are assembled, the moldingfand frame 5 are tightly interlocked with the rails and stiles, and solid portions p of the rails and stiles act to hold the molding in interlocked relation with the frame 5. In other words, this construction securely anchors the panel in the door frame.

The process of manufacturing the door is to make the insert frame 5 with mitred corvv1GO 11ers, as show n at 5a, and to lit the edges of the panel into grooves 5b of the frame, as the frame members are assembled. After the frame 5 has been Vmade in this manner and connected to the panel, the panel is run through a double panel raiser which makes the underlcuts C, both under-cuts being made in one operation on the two parallel sides l2. Subsequent to the time that the insert frame is lmachined in this manner, the moldings 6 which have been run in the usual manner on a molder, are mitred and attached to the insert frame by nailing them from their outer edges with the nails 8 spaced about a foot apart. After' the moldings have been attached in this way, the insert frame is comp-lete and is assembled in the stiles and rails as a complete panel; the stiles and rails having previously7 been prepared with the grooves l0 and lla to receive the tongues ll, and the whole is placed in an ordinary door clamp in the usual manner.

While a door of this character may be made in various ways, it has been found that the above construction'is the most practical way to make the same and avoid the disfigurement of nail holes showing in the surface of the moldings; besides, the molding is held much more securely when nailed separate from the face. This also makes a considerable saving in labor, as in the ordinary method of nailing the molding on to the insert frame, it requires from 50 to 60 small brads to hold the molding in position. With the described construction, this number may be reduced about one-half. Furthermore, as the nails are very small and heretofore had to be set in the molding, the time required is consideral ble, whereas if the molding is nailed from the back, as described herein, it is not necessary to set the nails, and it is much easier to apply them.

From the foregoing it is believed that the construction and advantages of a door in accordance with the invention may be readily understood by those skilled in the art, and it apparent that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.
