gan-BOTTOM.

' Speciiication forming part of Letters Patent No. 49,434, dated August 15, 1865.

' together with a like section of the bedsteadframe. Fig. 2 is atransverse vertical section thereof. Fig. 3 is a detailed view ot' one of the corners ot' the bed-bottom to show the joint. Figli is a representation ofthe socket by which thejoint is secured.

This invention consists in an improvement in the supports ofthe slats of spring bed-bottoms, and in their connections with such slats, and also in the mode of ]'ointing or securing the ends ot' their rails to each other.

A represen ts a bedstead-frame, composed of parts a., side boards, b, and end boards, h, made in the usual manner. It is here shown supporting my bed-bottom, whose frame, made up of two side rails, B, and two end rails, D, rests upon cleats fixed within the bedstead-frame. The ends of the end rails, D, are square, and are placed against the inner sides,next the ends of the side rails, B, in such way as that the ends of the rail B shall be flush with the the outer faces of the end rails, D. In this position they are secured to each other by means of a double-socket joint-piece, F, of peculiar shape, which is shown separately in Fig. 4 in top view. This joint-piece is most cou'- veniently and cheaply made by casting. The

end of the rail B is received in a socket formed` by the angular sides c e, that portion of the rail which rests therein being formed to a dovetail. The opposite side ofthe joint-piece F has also a socket, open only. on its upper side, its side g' being plain, the opposite side, g, having a lip, which takes into a vertical groove, f,cut on the outer face of the rail D, and the bottom edges of the sides g g/beng united byabottom piece, i, which supports the end of the rail D,

`as shown in Fig. 3. A joint-piece of like con-A .struction is placed on each joint of the bedbottom.

The springs which support the slatsC are y designated by the letter E. They are each formed of one piece of wire, so that their two sides are connected to make adoublesided spring whose ends are properly seeuredin the rails D. Their sides rise on an inclination, which takes a direction inward from the rails D, and the said sides are connected at their highest point by the crosspiece d,which in this example is an integral part of the wire,but i which maybe a separate piece rigidly fixed to the two sides ot' the spring. The length of this cross-piece is equal to the width of the slats, so that the latter", when resting thereon,may, asdthe springs are depressed,lie between their si es.

The slats C are of a length equal to that of the bed-bottom, and each of them hasapin,c, inserted through it near each end, which, pins are slotted transversely on their inner sides, as seen in Fig. 1, to receive the cross-pieces d of the spring when the slats are placed thereon. The slats are thereby locked to the springs, the tension of the springs causing the crosspieces d to draw constantly against the pins, and thus keeping them in the slots of the pins when the slats 'and springs are in their normal position. Moreover, the ends of the springs are bent slightly downward, so that their sides, when the cross-pieces are in place on the pins, rise abruptly along the sides of the slats and serve to keep them from lateral displacement. When the springs are depressed the slats are carried down still 'farther between the sides of the springs.

The slats maybe of any suitable number and material, and if any of them should become sprung or bent from longcontinued use, they can be turned over and the pins d be driven through, so as to bring their slots on the op-y posite sides of the slats, the slots being cutin the middle of the length ot' the pin for this purpose. r

My bed-bottom has several advantages over other spring bed-bottoms, and is also constructed differently from those now in use in several particulars. For instance, my slats run theentire length of the bed, and are easily detached from the springs, while the slats are entirely independent of each other. y

In some spring bed-bottoms now in use the slats are severally fastened to the springs by leather straps, andvin order to prevent lateral displacement, the slats are also connected to each otherby aleather strap. Where the springs are made with only one side or armtheir coils are usually kept in position by runningawooden roller through them, Whereas my springs need no such device, the springs being double and each coil assisting to keep the other true. When the slats terminate at the end of the spring the bedding droops and takes an ungracefnl appearance. My slats extend to the ends ofthe bed-bottom, and of course prevent this ungraceful appearance.

My slats are removed by depressing the springs at one end, separately from thc slat,
