MITER OR BEVEL JOINT.
Patented Nov. 8, 1887.

MITER OR BEVEL JOlNT.
SPECIFICATION forming part of Letters Patent No. 372.695, dated November 8, 1.887.
Application filedMay 7, 1886. Serial No. 201,429. (ModeL) T aZZ whom, it may concern:
Be it known that I, CASSIUS M. MERRI'DT, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certainnew and useful Improvements in Miter or Bevel Joints, of which the following is a specification.
The object of my invention is to improve the construction of miter or bevel joints,so as to render them stronger than those in common use, and to facilitate the manufacture of frames and the like; and the invention consists in providing the parts of the frame with groove and tongue, respectively, as will be hereinafter fully set forth and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 represents one corner of a frame in perspective, showing the application of the invention, Fig. 2, a sectional plan view of the same, showing the detail of its construction, and Fig. 3 a modification in perspectite.
Similar letters of reference indicate corresponding parts. I
From the drawings it will be seen that the invention is very simple, consisting. essentially, in the application of a groove and tongue to a miter or bevel joint. On one of the parts composing the frame A is formed a tongue, a and in the other part, 13, a corre sponding groove, Z). The groove and tongue may be of the usual form, with parallel sides, so as to be slipped or driven together laterally, as shown in Figs. 1 and 2; or they may be dovetailed, as shown in Fig. 3, and in the latter case are of course slipped together on the diagonal line. The former is intended to be used in connection with glue or nails, though when driven tightly together it makes 0 a comparatively strong joint with neither,
especially if the lumber is hard and dry.
The improvement is particularly useful in connection with nails, as it admits of their being driven altogether from the back side of the frame through the tongue, and thus being entirely out of sight. So, also, when glue is used, the tongue and groove not only serve to give great rigidness and permanence to the joint when finished, but materially facilitate the making of thejoint, since by forming the parts so as to go together tightly they may be simply driven together after the glue is ap plied, and the usual clamp for holding the frame until the glue sets may be dispensed with.
In practice I make the tongue parallel with the bevel-line, as shown in Fig. 2. This leaves the end of the tongue exposed to view, as in Fig. 1. It also leaves a vacant space in the groove at the inner angle of the frame. The latter effect is usually concealed by the glass or panel inserted in the frame, and the former is a minor consideration Where the face of the frame is chiefly exposed to view.
I am aware that the use ofthe groove and tongue in connection with miter or bevel joints is not broadly new, and I do not claim it as such; but in all the miter-joints employing the groove-and-tongue principle known to me the edge of the tongue forms a different angle or different angles from that of thejoint itself. Evidently this necessitates more than one operation in the formation of the connective parts, since the outline of the tongue and groove could not be formed in the making of the miter-line. This objection is removed by making the tongue and groove parallel with the miter-line, since the same cutter-head that forms said miterline makes the tongue or groove, respectively, requiring but one handling of the stock, and effecting a corresponding saving of time in the manufacture of the frames. Furthermore, by making the groove on the same diagonal line as the joint-line that portion of the frame is stronger than if the groove crossed the piece at right angles, and there is less tendency in the piece to split.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is 0 The described miter or bevel joint, which consists in the combination of the part A, having the tongue (1, and the part B, having the groove b, the edge of said tongue and the bottom of said groove being parallel with the bi- 5 seating-line of the joint, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
CASSIUS M. MERRITT.
