FRANCIS S. 11160, OF LOS ANGELES, CALIFORNIA.

TWIN BED.

Application filed October 22, 1914.

To all whom it may concern:

Be it known that I, FRANCIS S. INoo, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Twin Bed, of which the following is a specification.

The invention relates to spring beds, and particularly to those beds which are adapted to be used by two persons simultaneously, these beds being commonly called double beds in the trade.

Many beds have been devised for this purpose but they are ordinarily objectionable in that when two persons occupy them there is a tendency for the bed to sag in the middle and thus throw the two persons together.

The principal object of the invention is to provide a double bed which will be free from this central sagging tendency, so that it may be occupied with perfect comfort by two persons, each person occupying his own side and thereby enjoying all the comfort of a single bed.

A further objection to many double beds is that where they are occupied for long periods by a single person alone, the spring becomes distorted, sagging downwardly in the center, thereby unfitting the bed for a double occupancy if it is later desired to use it for this purpose.

A further object of the invention is to provide a bed spring which will be free from this tendency to sag in the middle so that it may be occupied by a single person for long periods without undue distortion.

Further objects and advantages will be evident hereinafter.

In the drawings, which are for illustrative purposes only: Figure 1 is a plan view of a bed spring, a portion thereof being omitted. Fig. 2 is a partial section on the plane w w of Fig. 1. Fig. 3 is a partial section on the plane m w of Fig. 1. Fig. 4 is a partial section on the plane m aa of Fig. 1.

In the embodiment of my invention illustrated in these drawings, a frame 10 is provided consisting of longitudinal pipe members 11 which are connected through castings 12 to cross bars 13 which extend entirely across the bed, the members 11, 12 and 13 forming a rigid and permanent framework of any desired dimension. Located on either side of the center of the bed are right and left hand net works 14 and 15, these net works being of inelastic construction and Specification of Letters Patent.

consisting of wire members formed into short links 16 and long links 17 the short links being used in the body of the net work and the long links being used to produce straight edges thereof. Centrally located in the bed is a center strip 18 which is partially elastic and which is preferably formed of spring members woven together to form an interlocked web. Located on either edge of the bed are edging strips 19 and 20 similarly formed from wire springs and preferably having a round shape as shown in Fig. 4. The strips 18, 19 and 20 are rigidly secured to the cross bars 13 by means of clips 21 and rivets 22. Secured in holes 23 in the cross bars 13 are a series of helical tension springs 24, one end of these springs being fastened to the cross bars 13 through the holes 23, and the other end of the spring being formed in an eye over which the ends of the links 16 and 17 are looped. The inelastic net wires 14 and 15 are secured to the elastic strips 18, 19 and 20 by means of tie wires 25, these tie wires being secured at either end to the springs 24 as shown at 26 and passing longitudinally of the bed, being looped througa the strips as shown at 27 and through every fourth joint of the net work as shown at 28 so that the net works 14 and 15 are secured to the strips 18, 19 and 20 by these tie wires 25. It will be noted that the tie wires are run very nearly straight so that there can be a slight longitudinal motion of the net works 14 and 15 with relation to the strips 18, 19 and 20. The springs 24 are made of such a strength that the net works 14 and 15 yield under the weight of the body, forming a comfortable bed and this yielding is considerably in excess of that of the members-18, 19 and 20, although these members yield somewhat when weight is applied thereto. The result is that while it is possible for a person to sleep across the strip 18 there will be relatively little yielding of this strip as compared to the yielding that would take place were the net works 14 and 15 formed in a continuous series without the strip 18. It will be seen therefore that the invention consists broadly of two inelastic net works elastically supported to the end cross bars, these net works being separated by an elastic strip which is rigidly secured to the cross bars in such a manner that the natural tendency of the center of any spring to sag is corrected by the insertion of the relatively unyielding central strip.

The invention further consists in two net works of any kind separated by a central strip, the central strip being less elastic than the two net works, so that each net work is free to yield separately without affecting the other.

I claim as my invention A twin bed spring comprising a frame having cross bars extending across each end of the bed, a partially elastic center strip secured at each end to the center of one of said cross bars, an edging strip of partially elastic construction secured between said cross bars at each edgeof the spring right Copies of this patent may be octained for and left inelastic net works each located be tween said center strip and one of'said edging strips, means for elastically securing the end of each net work to said cross bars, and

'means for slidably securing said net work to said center and edging strips.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 16th day of October, 1914:.
