' UNITED STATES PATENT. Orrron LIVERUS HULL, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN BED-BOTTOMS.

S pccffication forming part of Letters Patent No. 165,] 66, dated July 6, 1875; application filed January 20, 1875. I

To all whom it may concern:

Be it known that I, LIVERUS HULL, of Boston, of the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Bed-Bottoms; and do hereby declare the same to be fully described supporting-springs.

In such drawings, A denotes a 'frame composed of two side bars, a a, and three connection-bars,b b 1), arranged as shown, each of the said bars I) being tenoned into the bars a a. A seriesof conicc-spiral or helical springs,

B, have their base-coils arranged on, and fixed to, each of the bars I). Eachof such springs, at its upper coil, supports one of a series of slats, 0, arranged as represented, and said coil is held up against, and confined to, the slat by means of a duplex latch-lever, D, formed as shown in the drawings, and pivoted at its middle to that side of the slat against which the end coil of the spring is to bear.

By hooking the coil about the middle part g of the latch-lever and revolving the lever in the coil, the latter will be drawn hard up to the slat by the two arms h h, the detachment of the coil and slat being effected by turning the latch-lever in the opposite way the necessary extent. These latch-leversI usually apis a pair of the said brace-rods to each of the said outer cross-bars b b, a top view of one of said rods being represented in Fig. 7, wherein.

it is shown as bent at a right angle near each end, as represented at e e. The two rods of each pair cross each other, as shownin Fig. 3, and are at theirinner ends driven into the bar b. At their other ends such rods hook into staples f extending from the two outer slats.

A bed-bottom constructed in the above-described manner can easily be taken apart and packed in a small compass for transportation, and it can as easily be set up or put together.

I claim- 1. In the bed-bottom, the rotary duplex. latch D, pivoted at its middle to the side of the slat 0, against which the end coilof the helical springB is to rest or bear, and applied to such coil, all substantially as shown and described.

2. In the bed-bottom, the two pairs of brace-rods G G, arranged and combined with the base-frame A, the sets of spiral springs B, the series of slats G, and their connectionbands E E, all substantially as specified.

LIVERUS HULL.
