SPECIFICATION Tformngpart oflL'etters Patent No. 239,117, dated- March 272, 1881.

Application tiled September 9, 1880.

make and use the same, reference being had to the `accompanyingdrawings, and to letters or figures of reference marked thereon, which I form a part of this specification.

Our invention relates to improvements in I corner-irons for woven-mattress frames.

Heretofore the end and side rails forming the frames have been secured to the cornerzo irons by bolts, two or more heavy bolts being required i at each of the four corners of the frame.

rEhe object of our invention is to dispense with the use ofthe bolts, which end we accomz 5 plish by the peculiar construction of the corner-irons, by which they are adapted to be secured to the respectiverails in slots or grooves, and the use of bolts becomes unnecessary. Two of the corner-irons at one of the ends of the 3c mattress are adjustable, so that the tension of the mattress may be increased or diminished. The other corner-irons are non-adjustable, and are rigidly xed to the frame.

Our invention is further explained by referencetothe accompanying drawings,in which- Figure 1 represents an end view. Fig. 2 is a side view of an adjustable corner-iron. Fig. 3 is a front view of the adjustable corner-iron. Fig. 4. is a rear view of the adjustable corneriron. Fig. 5 is a perspective view of the. nonadjustable corner-iron constructed in a single piece.

Two nonadjustable corner-irons are used at one end of the mattress, and two adjustable 4 5 corner-irons are used at the other end.

1n the drawings like parts are represented by the same reference-letters throughout the several views.

A represents one of the side rails, both of @so which are provided at their respective ends` (No model.)

with slots B B, for the reception ofthe vertical'lugs C C ofthe respective corner-irons. The lower endsof lugs C are respectively pro- \'ided with langes l) l), by which'they `are prevented from being drawn upward through the'slotsBQ- F F are the endrails. The corner-irons are secured to the sidei'rails, A, by inserting the lug C in the slotfor recess B, when they are respectively drawn firmly toward the centers of the rails, and thus securely 6o retained by the tension of the mattress. When the corner-irons are thus attached to the respective ends of the side rails the end rails are placed at right angles thereto in the rel' cesses G G beneath the V-sha'ped lug E. Both 65 ofthe end rails are provided with angularl V- shaped grooves, conforming in shape vto the lugs E, in which said lugs rest.. Thus, as the tendency of the wire mattress is to draw the end rails toward each other, they are drawn 7o thereby back more firmly into the recesses G.

It is obvious that by this arrangement a rigid intleXible corner-joint is formed wit-hout the aid of bolts, and that the end rails are securely retained above, and in their proper relative position to, the side rails.

In the adjustable corner-irons the lugs C C are made detachable, and are respectively provided with flanges H H.

J is the central part or body of the corner- 8o iron, the lower surface of which is made con cave to conform to the convex surface of the upper edge of theside rails. The body J is provided with a dovetailed-shaped slot or recess, I, for the reception of the upper end of 8 5 the lug G, conforming in shape to the flanges H H, which are loosely fitted therein, and are adapted to be moved and adjusted therein by means of bolt M, nut K, and lug L. Lug L is cast in the same piece with and upon the 9o upper edge of lug C, and is retained thereby in the same xed relative position to the end of the side rail. The rear'end of bolt M engages in a slot in body J. Body J is adapted to be moved forward or backward on anges H H. Thus, when the mattress is tooslack, y the nut K is turned forward against the lug L, whereby the bolt M is drawn toward the lug L, carrying with it the end rail, thus increasing the tension of the mattress. 1f deroc sirous to lessen the tension of the mattress, the nut K is turned in the inverse direction.

N represents the ordinary spiral-wire mattress, the respective ends of which are secured to the end rails in the ordinary manner.

Having thus described our invention, we do not claim an adjustable corner-iron or an adjusting-screw for mattress-frames broadly, as we are aware that adjustable corner-irons provided with adjusting-screws are shown in Patents No. 171,042 and No. 224,028.

What we do claim as new, and desire to secure by Letters Patent, is-

1. The im provementin corner-irons for wovenwire-mattress frames herein described, oonsisting in body` J, provided with V-shaped lugs E, adapted to engage upon the edge and npper surface of the end rails, and .lug C, having lianges D D, said lugs being adapted to engage in slots in the respective ends of the side rails, whereby the end and side rails are rigidly retained in their proper relative position to each other, substantially as and for the purpose set forth.

2. Theimproved corner-iron herein described, z 5 consisting iu body J, provided with lug E and recess I, in combination with bolt M, and lug U, provided with flange D, lug L, and flanges H H, lug J being adapted to be moved and adjusted all substantially as and for the pur- 3o pose set forth.

3. The combination of side rails, A, provided With slots B, the corner-iron consisting in body J, provided with lugs E and C and end rails,

F, and the corner-iron J, provided with lug E 3 5 and recess 1,1ug (j, provided with lange D, lug L, and langes H H, lug J being adapted to be adjusted substantially as set forth.

In testimony whereof we affix our signature in presence of two witnesses.
