mrnovnn seme-BED BOTTOM.

The Schedule referred to in these Letten Patent and making part of the lame.

I, JEREMIAH N. BULL, of Springfield, Hampden4 county, Commonwealth of 4lidassachusetts, have invented a new and improved Spring-Bed Bottom, of which the following is a specification.

My invention relates to that class of bed-bottoms constructed with a frame fitting upon the bedstead, and slats running lengthwise of the bed, supported at each end by springs attached to the cross-bals of' the frame; and

My improvements consist--V First, in arranging and coi as to fill up the spacebetween the, end of the slats and the cross-bar, and

Second, in 'so arranging the leather connections between the springs and the slats that thelatter maybe reversed, and also so that, when in use, they may be kept in a horizontal position, and be prevented from twisting, so as to present the edges of the slats to the bed when a weight is brought to bear on them at one side of the slat.

In the drawingstom'.

Figure 2 is a side elevation of one end ofthe slat, showing the manner of attaching the leather to the slat, and the form of the spring and its attachment to the cross-bar.

I will now describe the construction of my spring:

It is formed with two coils, A B, passing around toward the cross-bar D, in the form of a loop, c, and

nstructing the springsA so Figure 1 is a plan view of my improved bed'bot' fills up-the space between the sides a c of the spring,

so that, when the slat is brought down by a weight upon it, this loop c and the sides a a of the spring form a continuation of the slat G, and support the bed, thus filling up the space between the end of the slat and the cross-bar D.

The slat vis so-formed that either sidemay be used uppermost, andthe leathers E E are fastened in a out made in` the end of the Slat, thus requiring less leather, and making asmoother and better appeal'- ance, besides being a stronger mode of attaching than the common fmethod of nailing upon the .outside of the slat;

Also, by this means, the slat is made reversible,

presenting the same surface whichever side is placed uppermost. y

By this construction I obtain a neat, durable, and cheap form of bed-bottomand remove several objections now made against the common bed-bottoms in use, my spring being so formed that the space.,

between the end of the sla-t and the cross-bar is iilled up, thus doing away with the necessity of using a bolster to iill up this space, and, further, the manner of attaching prevents the slat from twisting, and the slats are so formed as to 'be reversed quickly, and present the same surface whichever Yside may be uppermost.

I claim the spring for bed-bottoms formed with the two coils A B, the two hooks b b', and the loop c projecting backward from the said hooks b b', when used in combination with the leather connection E, formed with `two holes for receiving the hooks b b', and attached to the slatvG, substantially as shown anddescribed.
