PATENT EDWARD EVERETT SQUIRES, OF SEATTLE, WASHINGTON, ASSIGNOR OF ONE-HALF TO CHARLES E. HAYDON, OF SAME PLACE.

FRAMING-JOINT.

SPECIFICATION forming part of Letters Patent No. 643,552, dated February 13, 1900.

Application filed April 2 7, 18 9 9.

To all whom t may concern,.-

Be it known that I, EDWARD EvERETr SQUIRES, of Seattle, in the county of King and State of Washington, have invented a new and Improved Framing-Joint, of which the following is a full, clear, and exact description.

The invention relates to the manufacture of doors and like articles; and its object is to provide a new and improved framing-joint more particularly designed for use in the manufacture of doors and the like, and which joint is simple and durable in construction and arranged to securely fasten the rails and stiles together to give'additional strength to the door and prevent the members of the joint from becoming loose from side pressure incident to the opening and closing of the door.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views:

Figure 1 is a cross-section of the rail. Fig. 2 is a like view of the stile. Fig. 3 is a reduced side elevation of a corner of a door provided with the improvement. Fig. 4. is a like view of a modied form of the improvement. Fig. 5 is a similar view of another modifiedv form of the improvement, and Fig. 6 is alike view of still another modified form of the improvement.

The stile A, as shown in Figs. 2 and 3, is provided with a longitudinallyextending groove B, having its side walls B curved and terminating in a bottom B2 somewhat less in width than the opening B3 at the top of the groove B. The stile A is formed with moldings or stickings C, having their inner faces forming part of the. side walls B of the groove, said moldings or stickings forming clampingjaws, as hereinafter more fully described, the outer sides terminating on shoulders D.

The rail E is provided with a tenon F, having its sides corresponding to the sid'e walls B of the groove B, the bottom F' corresponding to the bottom B2 of the groove, so that when the tenon is driven into the groove B Serial No. 714.764. (No model.)

it completely fills the groove. The rail E is further provided with copings G on opposite sides of the tenon, the copings terminating in shoulders H, adapted to engage and be seated on the shoulders D of the stile A. Vhen the tenon F is driven into the groove B, the stickings or moldings O are somewhat spread apart to be iinally pressed inward by the copings G at the time the rail is driven home, so that the copings press the stickings or moldings in firm contact with the sides of the tenon F- that is, the stickings or moldings act as jaws to firmly clamp the tenon. The groove B eX- tends throughout the length of the stile A, and the portion between the two rails is filled by the edge of the panel I, as will be readily understood by reference to Fig. it.

The side Walls B of the groove B may terminate in an edge, as illustrated in Figs. 4. and 5, or the said side-walls maybe beveled,

as indicated in Fig. 6, to form a regular dove-` tail in the stile A' for the correspondinglyshaped tenon F2 of the rail E.

It will be seen that by the arrangement described the joint between the stile and the rail gives considerable strength to the door, especially as the latter is subjected to a side pressure incident to the opening and closing of the door.

In manufacturing the door the tenon F, copings G, and shoulders H are provided with glue or other binding material previously to driving the tenon into the groove.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A framing -joint having one member formed with a tenon and with copings, the said tenon being reduced at theY base, the other member being formed with a longitudinal groove shaped to correspond to said tenon, and provided with clamping-jaws at the outer sides of the groove, the said jaws being adapted to lock over the said 'tenon and the copings being arranged to engage the said clamping jaws, substantially as shown and described.

2. A framing-joint having its stile formed with a longitudinal groove, stickings or moldings having clamping-jaws at the outer sides of the groove, the opening between the jaws IOO ders at the bases 0f the eiampng-jmvs, substantially as shown and described.
