IMPROVEMENT IN SPRING BED-BOTTQMS.

Specification forming part of Letters Patent No. 138,446, dated April 29, 1873; application iiled September 30, 1872.

To all whom it may concern:

Be it known that I, WILLIAM STARKE, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Spring Bed-Bottoms, of Which the following is a specication:

The nature of the present invention consists in combining transverse slats with longitudinal slats by means of eyes in the top ends of the springs, and rods which pass through the eyes and across the longitudinal slats and bendA down at right angles at the edges ot' the side slats and pass through the bottoni frame and prevent the upper section from having a lateral movement relative to the lower section, While, at the same time, the upper section may have an easy vertical reciprocating movement on thesprings, as hereinafter fully described and shown.

In the drawing, Figure-l is a plan or top view of my improved bed-bottom, Fig.2, an end elevation ofthe same; Fig. 3, a broken-plan view of one of the spring-slats, showing the mortise through Which the eye of the spring passes 5 Fig. 4, a broken elevation'of one of the springs, showing the construction of the eye.

A A represent the longitudinal slats of the bottom, and B B B the transverse slats which support the slats A and are held to th em, as hereinafter described. The upper ends ofthe springs I haveformed on them eyesd d, Sto., by bending the Wire around some suitable form, said eyes being long enough to pass through the transverse slats B and longitudinal slats A. The slats A and B, when in position, bring the longitudinal slots or mortises of parallel to each other, so that the eyes d will readily pass I thro ugh. Wh en the eyes are in position through the slats the wire rods C C C areput through the eyes d on top of the slats A and bent down at the sides ot' the bottom, as shown at D D, and put through the bottom frame G, and are then bent inward at right angles, as shown at E, Fig. 2.

This arrangement is such that When the slats A have weight placed on them the bent rods D D pass through the frame Gr, as shown at Fig. 2, F, the ends E preventing the slats A from rising too high.

The rods are to be made ot' such-sized Wire as will prevent the upper section of the bottom from having a lateral movement, and they should have a suitable springing quality, to

prevent them from sta-ying bent by ordina-ry use. This device differs from the bottom patented to B. R. Boyington, September 3,1867, first, inasmuch as in his bottom there are no transverse slats to support the longitudinal slats; second, because he holds the springs to the slats by straps which Will not prevent the upper section from having a lateral mot-ion when said section has the Weight of an ordinary person thereon, the straps then being loose.

By means of the eyes d, rods C,'and mortised slots the bottom is firmly held together and is very simple, cheap, and durable, While, at the same time, the slats A are always held the proper distance apart.

I disclaim the eyes on the springs, as described in said Boyingtons patent; but

I claim- The combination of the longitudinal and transverse slats A B, spring I d, and rods D, which pass through the eyes, hold the slatsA B together, bend down at the side, and pass through the lower section, and prevent the upper section from having a lateral motion, as and for the purpose set forth.

WILLIAM STARKE.
