July 8,1930. c. w. COLEMAN I WOOD DOOR CONSTRUCTION Filed Feb. 15, 1929 Patented July 8, 193% urra srrss PATENT OFFICE CHARLES W. COLEIdAN, OF DUB'UQUE, IOWA, ASSIGNOR TO CARR, RYDER & ADAMS COMPANY, OF DUBUQUE, IOWA, A CORPORATION OF IOWA.
v WOOD DOOE CONSTRUCTION Application filed February 15, 1929. Serial No. 340,051.
This invention relates to doors, and particularly to the wood panel type of doors formed of veneered material, and its principal object Y is to provide a strong and substantial door construction wherein a soft wood core or filler, surfaced with a thin hard wood layer, is used in the insert door frame or connection between the panel and outer door frame whereby the use of thick hard wood lumber is eliminated in any part of the door.
Another object is to provide a veneered wood insert door frame of which the soft wood core is surfaced with veneered material having a relatively thin part adjacent the panel and a thicker stepped up part in the corner formed between the insert door frame and the outer door frame, thereby forming a fillet for such corner, which construction not only greatly adds to the attractive appearance and symmetry of design, but materially increases the rigidity and solidity of the door construction. Another object is to provide a veneered door construction wherein the use of thick hard wood material is eliminate-l. Another object is to provide a door construction having an unnailed insert frame, interconnecting the outer door frame and panel.
\Vith these and other objects and advan tages in view, this invention consists in a wood door construction of the panel type wherein the insert door frame between the panel and outer door frame is composed of unnailed material or solid material, or composed of a soft wood core and a hard wood surfacing material shaped to provide a fillet on each side of the door at the inner edge portion of the outer door frame.
This invention-further consists in the several novel features of construction, arrangement and combination of parts hereinafter fully set forth and claimed.
The invention is clearly illustrated in the drawing accompanying this specification in which Figure 1 is a side elevation of a wood door construction embodying a simple form of the present invention;
Fig. 2 is a perspective view of a fragment of the insert door frame; and
Fig. 3 is a detail fragmental horizontal cross section taken on the line 33 of Fig. 1.
' Referring to said drawing, the door comprises an outer or door frame 5, a panel 6 and an insert door frame 7 joining the panel with the outer or door frame. The door frame 5 is composed of stiles 8 and rails 9 joined together by the usual dowel construction, and the inner edge of the outer door frame is rabbeted as at 10 to receive the insert door frame. If desired, the stiles and rails of the outer door frame may be composed of veneered material comprising soft wood cores 11 covered on their sides by hard wood surfacing material 12, the edge portions also being composed of hard wood material 13. The soft wood core may be composed of strips or-pieces of soft wood, all glued together, and the surfacing material is glued to the core in the usual manner of forming veneered wood material.
The insert door frame 7 is composed of veneered woodmaterial, and comprises vertical and horizontal pieces 7 mitered together at the corners and received and secured in the rabbeted edges of the outer door frame 5. The pieces which comprise the insert door frame are composed of soft wood cores 14 formed of strips or sticks glued together, upon the sides of which aresuperimposed thin hard wood surfacing material 15 glued thereto. If desired, the edge strips 16 of the insert door frame may be composed of hard wood, and said strips project beyond the inner edge of the surfacing material 15 and are rabbeted along their inner edges, as at 17, to receive the panel 6 which, if desired, may be composed of veneered wood material.
The hard wood surfacing material 15 of the insert door frame comprises a relatively thin portion 18 adjacent the inner part of the frame, and a thicker portion 19 which is stepped up to increase the thickness of the frame at the place where it enters the rabbet of the outer door frame, thus to all intents and purposes forming a fillet in the corner between the outer door frame and the insert door frame. If desired, the soft wood core 14 may protrude beyond the outer edges of the hard wood surfacing material 15 to form a tongue 20 that enters the depressed portion 21 of the rabbet 10.
til
The insert door frame is secured around the panel, after which the outer door frame is secured around the insert door frame. It will be observed that the connection between the panel and outer door frame is thicker than the panel and is stepped up from the material from the sidesvof the panel to the sides of the outer door frame, a rigid connection is provided between the panel and door frame in which a minimum amount of hard wood lumber is employed.
The surface material of-the whole insert frame may be formed to the desired shape in one operation, making a substantial and jecting beyond said thickened portion in the form of a tongue which enters a groove at the bottom of the rabbet in the outer door frame.
In testimony whereof, I have hereunto set my hand this 7th day of February, 1929.

I claim: 1. A wood door comprising in combination an outer door frame rabbeted on its inner edge, arpanel, and a veneered insert door containing a soft wood core and frame connecting said panel with said outer door frame and secured n the rabbet of the outer door .frame,the outer layers of the veneered insert doorframe being relatively thin and thickened towards the outer margin of the insert outer frame.
2. A wood door comprising in combination an outer door frame rabbeted on its inner edge, a panel, and a veneered insert door frameconta ning a softwood core and rab- 'beted on its inner edge to receive the panel and secured in the rabb'et of the outer door frame, eachouter layer of the veneered insert door frame having a relatively thinpart located adjacent its inner edge, and a stepped up part forming a thicker portion located at its outer edge and forming a fillet in the corner between the'insert door frame and outer door frame.
3. A wood door comprising in combination an outer door frame rabbeted on its inner edge, a panel, and a veneered nsert door frame rabbeted on its inner edge to receive the panel and secured in therabbet of the outer door frame, said insert door frame having a soft wood core and a hard wood inner edge portion, the soft wood core having hard wood veneer material on its two'sides thickened adjacent the outer edge to form a. fillet on each side of the door between the insert door frame and the outer door frame and connecting the panel with said outer door frame, the core of the insert door frame pro-
