SPECIFICATION forming part of Letters Patent No. 749,709, dated January 12, 1904.

, Application s February 16, 1903. Serial No. 143,713- (No model.)

To all], 1072,0121, it ntrty concern:

Be it known that I, MILLARD E. STOCKWELL, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Furniture, of which the following is a specification.

This invention relates to improvements in metal furniture, as chairs, tables, stools, &c.; and its objects are, first, to utilizeelliptical or flat'tubing in the construction of the framework of this class of furniture; second, to dispense with the use of screws, bolts, &c., in assembling the framework of this class of furniture, and, third, to assemble the legs and leg-braces for metal furniture, having the metal folded and the back edges turned or curved in to avoid sharp or rough edges, without the use of screws or bolts for securing the braces. These objects are attained bythe mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation of a chair. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional plan of the frame on line a: Fig. 1. Fig. i is an elevationof a legcut away at K to show the manner of securing the brace. Fig. 5 is a sectionalplan of a leg on the line a: w of Fig. 1., Fig. 6 shows a tube made of 'sheet metal with the back edges turned in and meeting to form a practically square edge. Fig. 7 is an elevation'of a portion of a leg with the braces cut off at y y of Fig. 8 and showing the manner of assembling these parts with legs formed of sheet metal and having the back edges turned in, but not meeting, and Fig. 8 is a sectional plan of the same on the line y y of Fig. 7 Fig. 9 is a sectional side view, on the line Z Z of Fig. 10, of a leg formed of sheet metal and having the back edges rolled or curved, but not meeting, showing the manner of attaching the braces; and Fig. 10 is a sectional plan of the same on the line Z Z of Fig. 9. Fig. 11 is a back elevation of an oval or round leg made of sheet metal with the back edges meeting, with the rails cut off on the line o o of Fig. 12 and showing the manner of securing the rails; and Fig. 12 is a sectional plan of the same on the line c o of Fig.

11, showing the ends of the braces interlocked. I

Fig. 13 is a sectional end viewof a chair-back on the line it of Fig. 2, showing the manner of inserting the slat or spindle. Fig. 1 1 is a sectional perspective, and Fig. 15 is a sec-- tional elevation, of the top of a legon the-line W W of Fig. 3, showing the manner of introducing the flanges by means of which the legs are secured to the top. Fig. 16 is a sectional side view of the back on the line t t of r Fig. 13, showing a provision for preventing the back from sliding upon the slat or spindle; and Fig. 17 is a bottom pl'anof the same. Similar letters refer to similar parts throughout the several views.

A represents the top or seat, as the case may be.

10, so that the braces C may pass between the edges, as in Figs. 9 and 10.

In constructing the leg-frame of a piece of furniture the legs B when made of full oval or elliptical tubing are mortised, as at Z), for the reception of the ends of the braces C, two of said braces entering each leg, as in Fig. 5, the lower edge being notched, as at 0, so that the edge of the tubing will enter it, as in Fig. 4, and the upper edge is beveled down toward the end, as at C, so that-the ends of the rails may be entered into the mortise until the notch c engages the wall of the tube without binding, and when the top of the legs B are carried toward each other, as indicated by the When an oval tube is formed of sheet metal, as in Fig. 11, the mortise and braces should be dovetailed, as shown at 0? cl, and the ends of the braces interlocked, preferably as shown in Fig. 12, so that there will be no possibility of the tube spreading by reason of the strain upon the braces.

When the legs are formed of sheet metal with the back edges turned in and some distance apart, as in Figs. 8 and 10, it is advisable to pass a rivet or rivets G through to prevent them from spreading. When the edges are turned, practically, square in, as in Figs. 7' to 9, the ends of the braces may be curved, as in Fig. 8, to hold the braces apart to position and dovetailed into the edges, as indicated in Fig. 7; but when the curved edges, as in Fig. 10, are usedthe ends of the braces will enter the same, as in Fig. 4, and two rivets Gr and Gr are inserted. These rivets serve a double purpose: first, to prevent the legs from spreading at the back or open portion, and, second, to receive and support the strain of the legs upon the braces, substantially as explained in connection with the description of Fig. 4:.

The legs are secured to the top A by means of flanges F, preferably constructed with downwardly-projecting plugs f, that enter the upper ends of the legs'and are securely attached thereto in shape, so that they may be screwed solidly to the lower surface of the top.

In furniture requiring upwardly-projecting backs, as chairs, &c., the main posts D are secured to the lower side of the chair-seat well forward, as indicated at a in Fig. 1, and are formed of a single piece of tubing, as shown in Fig. 2, and the spindles E are secured thereto by mortising through the main post, as at Z in Fig. 13, and passing the slats through until the upper ends, which are curved, as at e, bear against the upper inner surface of the tube, as shown in Figs. 13 and 16, and the danger of the tube slipping upon the slat when carrying the chair thereby may be averted by springcatches 03, formed from-the tube at the ends of the mortises arranged to engage corresponding notches in the edges of the slats, as indicated in Figs. 16 and 17 or in any other available way. The lower ends of the slats may be secured to the seat by means of screws, as at e in Fig. 1, and the two outside slats may be made of a single piece of metal, if desired.

Having thus fully described my invention,

lower edge, and interlocked in pairs closely fitting'said mortises, substantially as and for the purpose set forth.

3. In furniture construction, a top, tubular legs, open at the back and the edges turned in, secured thereto, rivets passing through the tubes braces having the ends notched and fitted to enter said tubes in pairs and engage the pins substantially as and for the purpose set forth.

4:. In furniture construction, a top, tubular metal legs secured thereto and each of said legs provided with an opening for braces, braces having notches in the lower edge near the ends and fitted to enter said openings and rigidly support the legs; with a back made of a single piece of metal tube bent and having narrow mortises through the lower wall, and slats fitted snugly into said mortises and having the upper ends formed to fit the upper inner surface of the tube, the opposite ends thereof secured to the under side of thetop, forming a chair-back, substantially as and for the purpose set forth.

5. In'furniture construction a chair having a top tubular legs secured thereto and braces supporting said legs, in combination with a tubular back post in one piece and having mortises through the walls, catches formed at the end of said mortises, slats entering said mortises and having notches corresponding with the catches, the lower end of said slats secured to the chair-seat, substantially as and for the purpose set forth.

Signed at Grand Rapids, Michigan, February 6, 1903.
