IMPROVEMENT IN PICTUREFRAMES,.&C. l

Specicaton forming part of Letters Patent No. 122,153, dated December 26, `1871; antedated December 21, 1871.

To all whom it may concern:

Be it known that we, GEORGE E. (loLLINs and WILLAED C. O oLLINs, of Bucksport, in the county of Hancock and State of Maine, have invented a new and useful Improvement in Picture and Mirror Frames; and we do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of our invention sufficient to enable those skilled in the art to which it appertains to construct the same;

This invention relates to a new and improved mode of securing the miter-joiuts at the corners of the frame; and consists in 'cutting at a right angle to the ruiter, across the back of the frame,

Aone or more saw-cuts to a suitable depth', in

which are inserted metal strips or ties, which are formed to embrace a part or all of the outer edges of the frame to the depth of the cut, and extending from one end of the cut around the angle of the frame to the other, thereby obviating the usual method of nailing the joints, and not only facilitating the process of uniting the parts with glue but renderingthe frame more durable and neater in appearance.

Figs. l, 2, and 3 are diiierent modifications of my invention, shown in perspective; and Fig. 4 is a vertical section taken on line X Y, Fig. 3.

Similar letters of reference indicate like parts in the several gures.

In the drawings, A the frame which intersect on A represent two sides of the nliter-line X Y,

Fig. 3, in the usual manner. At suitable points upon the miter saw-cuts are made at a right angle thereto, of a sufficient depth across to the outside edge of shown at e a, Fig. 4.

the frame; these cuts are plainly In Fig. l but one cut is made across the corner of the frame, and in it is inserted the metallic tie a, theends of which are folded upon the edges of the'frame, as shown at b b. In Fig. 2 the metal band after passing through line a, extends around and embraces the corner as shown at cc,wl1ile in Fig. 3 the through cut a extends along part of the distance to d d, whence it extends of the frame, band after passing the edge of the frame a the corner, as shown at across the corner of the frame in line or cut e,

as shown.

When using these bands the joint is glued in the usual manner when the band is driven into the saw-cut, and the joint less cost than by the usual method ot' nailing.

What we claim as new, and Vdesire to secure by Letters Patent, is-f l. Securing or re-enforcing the miter-joints of picture and mirror frames, by means oi' a metal band inserted in a groove or cut, a, made at a right angle with such joint, or nearly so, the tie extending along the edge of the frame so as to prevent the separation of the parts, substantially as shown in Fig. 1. j

2. Securing the joints of picture and mirror is iirmly secured with frames by a metal tie inserted in a cut or groove, i

a', and embracing the corner of the frame, as at c c, substantially as shown in Fig. 2.

3. l Securing the ruiter-joints of picture and mirror frames by a metal tie passing twice across the corner of 4the! frame'at c c, and embracing a portion of the edge stantially as shown in Fig. 3.
