BED=SPRING.

SPECIFICATION forming part of Letters Patent No. 405,821, dated. June 25, 1889.

Application filed January 10 1889. Serial lilo. 295,978. (No model.)

To aZZ whom it may concern:

Be it known that we, ELLIOTT M. BONNELL and JOHN S. LAMBING, citizens of the United States, residing at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Bed- Springs; andwe do declare the following to be a full, clear, and exact d cscription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bed-bottoms composed of spiral or helical springs, and the novelty will be fully understood from the following description and claims, when tak n in connection with the accompanying drawings, in which- Figure l is a plan view of a bed-bottom constructed according to our invention; and Fig. 2 is a sidetview of the same, showing th bottom partly folded.

Referring by letter to the said drawings, A indicates helical sprin s, there being any suitable number employed, according to the size of the bed-bottom desired.

13 indicates a coiled or spiral wire adapted to extend cntirel around the margin of the bed-bottom. This marginal wire, which also serves as a connection. for the outer springs, is coiled around the outer portion of the upper and lower whirls of the springs A, and at the corner springs this wire connection I; is coiled around the whirls of said spring in a somewhat angular position.

In practice it is desirable to have the bottom so that it may fold, and in such cases, instead of carrying the marginal wire along the entire length and width of the bottom, such wire or spiral connection is severed, as shown at a, so that no interruption will be offered in folding the bottom, which will be virtually composed of two sections or more, as found nccossar C indicates spiral wires whichare arranged in parallel rows and wrapped around the innor portions or adjacent portions of the whirls at opposite ends of the springs A in a manner similar to the marginal wires. These spiral wires 0, which yicldingly connect the springs A, also serve to partly fill the interspaces formed by the arrangement of four springs, as shown at b.

D indicates aspiral wire, which is of a construction substantially the same as the wires 0, and is loosely carried around the adjacent portions of the top or bottom whirls of the springs A. In this construction it should be stated that when it is desirable to attain a hinge for the sections the spiral wire I) should not beuscd atthe opposite ends of the springs A at the same time, as better shown in Fig. 2 of the drawings, and it will also be observed that this spiral wire- D, as well as serving the purposes of loosely and yieldingly connecting the springs A and presenting a spiral filling for the inter-spaces 1), also serves as a hinge for the said springs.

lVhile we have illustrated the bed-bottom with helical springs, yet in some cases itmay be found desirable to employ conical or other forms of coil-springs.

lVe are aware that it is not new to connect the tops and bottoms of bed-springs with spiral wires, and therefore do not claim such, broadly.

We are also aware that springs have been provided with hinged connections.

llaving described our invention, what we claim is 1. A bed-bottom consisting of helical or other springs, a spiral marginal wire wrapped loosely around the outer portion of the top and bottom whirls of each spring, intermediate spiral parallel wires 0, uniting the adjacentportions of the top and bottom whirls, and a similar spiral wire on but one side of the bed-bottom, serving the twofoldjunctiou of connecting the sections of the springs and forming a hinge for said sect-ions of the bedbottom, substantially as specified.

2. A spring bed-bottom formed in sections and having the top whirls of springs at the adjacent ends of the sections united by a spiral wire wound loosely around them, so as to allow the sections to fold and yet all'ord a yielding connect-ion, substantially as spcci tied.

In testimony whereof we altix our siguat u rcs in presence of two witnesses.
