MATTRESS-FRAME.

SPECIFICATION forming part of Letters Patent No. 763,443, dated June 28, 1904.

- Application filed October 15,1903. Serial No. 177,161. (No model.)

T 0 all. whom it may concern:

Be it known that we, FREDERICK J. VAN Cisn and VILLIAM (J. VAN CISE, citizens of the United States, and residents of Mayville, in the county of Chautauqua and State of New York, have invented a new and useful Mattress Frame, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The invention relates to frames for wovenwire mattresses; and the object of our improvement is to chcapen-and strengthen a former metallic mattress-frame as shown in an application for Letters Patent filed February 14:, 1903, and given Serial No. 143,326. Our purpose is accomplished by making the side and end rails of sheet metal with flanges thereon, as formerly, and then to so cut and'turn a tongue from the lower flange on the end rail that said end rail may have a broad direct bearing on the top of the side rail, and 'when the corners are thus fastened together, as hereinafter described, extreme rigidity is imparted to it.

In the drawings, Figure 1 is a side elevation of a corner of our mattress-frame, showing our method of attaching the end rail to the side rail. Fig. 2 is an end elevation of one corner of a mattress-frame, showing a cleft in the lower flange of the end rail. Fig. 3 is a plan view of the under side of a portion of theend rail, showing the broad bearing for the top of the side rail.

Similar numerals refer to corresponding parts in the several views.

The numeral 1 is thefabric, which is usually made of woven wire.

The frame is composed of side rails and end rails 9, which are made of two pieces of sheet metal. The lower piece 3 is made in a V shape with a cylindrical lower side 4. The upper edges are turned outward in flanges 5 5. A cap-piece 6 extends straight across the top of the V-shaped piece 3 and rests on its flanges 5 5. The edges of the cap 6 are turned down around flanges 5, thereby forming two strong flanges 7 7 at the upper corners of the rail. The parts of flanges 7 are held in place by the sides of the V-shaped piece 3, being sprung into cap 6, and also by rivets 8 8, which are placed at suitable distances along the flanges.

The end rails 9 and side rails 2 are usually made the same size and shape with the exception of the upper flange 10 of the end rail 9, which is usually made of greater width for a purpose hereinafter described. A wooden core 11 is inserted throughout the entire length of the end rail, and a wooden plug 12 is inserted, as shown in Fig. l, in the ends of the side rail.

In forming the corners of the mattressframe end rail 9is placed upon its side upon the side rail 2, the lower flange of the end rail being cut as'at 13 in Fig. 2. The cleft portion of the flange extends out at the angle of the rails side, forming a broad flat bearing, as shown in Fig. 3, also forming a tongue 14, which can be fastened to the end rail by means of a screw, bolt, or nail 16 in hole 15, which screw, bolt, or nail 16, in combination with a corner-bolt 17, which extends down through the two rails and clasp-piece 18, rigidly holds the corner as against all strains from tension or torsion. The cleft edges of the lower flange at out 13 bind on each side of the flanges 7 7 of the side rail and assist the corner-bolt 17 and screw 16 in giving rigidity to the whole corner construction.

' The woven-wire fabric 1 is cut the correct length desired for the mattress and is fastened by being placed against the outer side of the upper flange 10, as in our former construction, and a clamping-bar 19 is placed upon it and firmly secured in place by bolts 20 at suitable distances. The fabric then extends up over the edge of the upper flange 10, which is made of greater width, as above stated, in order to raise the wire fabric a sufficient distance from the rails. It is then fastened in the same manner to the other end rail of the frame and is stretched in any suitable manner until it can be secured by corner-bolts 17 and screw or nail 16. This arrangement protects all the projecting points which would be likely to catch and tear the bed-linen and also gives a neat strong finish to the mattress end.

It is apparent that in placing the end rail directly on the side rail and doing away with
