. a specification, reference being had therein to the accompanying drawings.

The invention relates to a construction of corner, being more particularly designed for use in carriage construction.

In the drawings, Figure 1 is a perspective view of the inverted corner with the metallic angle detached. Fig. 2 is a bottom plan view of a corner, and Fig. 3 is a section on line :10 0c of Fig. 2.

In the present state of the art carriagebodies are usually formed of light construction, and on account of the thinness of the boards used it is difficult to join them so as to provide the necessary strength. Various constructions have been made in which the corner of the box is strengthened by metallic angle-irons; but these are usually arranged to overlap the sides of the box, so as to avoid danger of splitting the thin side boards. In the present construction the corner is strengthened by a metallic angle, which is applied merely to the bottom of the box and is not exposed to view at the sides, said angle being of peculiar construction, so as to prevent danger of splitting the wood by the securing devices.

As shown, A and B are the two adjoining sides of the body, and O is the sill, the end of which fits the corner between the sides. This sill is usually made of hard wood, whereas the side panels are of soft wood and are very thin. D is a suitable corner-post which is fitted in the angle between the sides A and B above the sill 0. Thus the post D forms a brace between the two sides.

To tie the sides A and B together and to the sill O, a metallic angle F is used. This is adapted to bridge the joint between the sides and the sill O and is provided with a series of apertures a and b, respectively, upon opposite sides of the joint between the side boards and the sill. These apertures provide for the passage of securing pins, nails, or screws G. The angle F is so arranged that the apertures a are spaced from the joint sufficient distance to provide a firm hold for the nail or screw without danger of splitting the block. Inasmuch, however, as the sides A and B are formed of very thin material, the aperture 1), even if registering with the center line of the sides, would be so close to the opposite edges as to endanger splitting. I have therefore overcome this difliculty by arranging the a erture I) very close to the inner face of t e side, so as to leave considerable material between the fastening-nail and the outer face of the side. The outer edge of the angle F is then provided with a flange 0, preferably notched to form a series of points, and these are driven into the wood of the sides A and B. These points being very thin will not split the sides, but will nevertheless obtain a firm grip upon the latter, so as to clamp them to the sill O and prevent splitting by the screws or nails G engaging the apertures b.

With the construction as above described it will be observed that there is nothing to mar the appearance of the body in the way of an exposed joint or angle at the corner, and at the same time the strength of the metallic angle F is imparted to the corner-joint.

I/Vh at I claim as my invention is 1. In a carriage-body, the combination with adjacent sides, of a block fitting the inner faces of said sides at the corner, and a metallic angle bridging the joint between said block and sides around the corner, being provided with apertures for securing devices on opposite sides of said joint, and with its outer edges turned notched and embedded in the edges of the sides, and securing devices passing through said apertures into the sides and block.

2. In a carriage body, the combination with adjacent sides, of a filling-block engaging the angle between the inner faces of said sides, of a metallic angle F having the turned outer flanges c, and the double series of apertures a and b, said angle being arranged to bridge the joint between the sides and block, and securingpins passing through said double series of apertures and respectively engaging the block and the sides, and the flanges a being embedded in the edges of the sides, the pins in said sides being arranged near the inner faces thereof between said inner faces and said embedded flanges.

3. A metallic angle for box-corners, comprising an L-shaped plate having its outer edges turned to form flanges and notched to form a series of points and a double series of apertures for the securing nails or screws, substantially as and for the purpose set forth.

4. A carriage-body, comprising a sill, side IIO and end panels adjoining each other, and secured'respectively to the side and end of said sill, and a metallic angle bridging the joint between said sides and sill' at the bottom thereof, being provided with notched flanges for embedding in the sides and end a seriesof apertures between said flanges and the line of joint with the sill, a second series ofapertures in the portion underlapping thesill, and securing-pins engaging said apertures and embedde in the sides and sill. I

I 5. In a carriage-body, a sill formed of hard wood, thin side and end panels of soft wood adjoining each other, and secured respectively tovthe sides and end of said sill, an L- shaped metallic angle underlapping the joint between the panels and sill, being provided embedding in with projecting points at its outer edge for tures between said points and the line of joint with the sill, a second series of apertures in the portion underlapping the sill, securingpins engaging the latter series for fastening the angle to said sill, and securing-pins engaging the first series and embedded in said panels, the latter being held from splitting by the embedded points of said angle and the securing of thesarne to the sill.

In testimony whereof I affix my signature in presence of two witnesses.
