COUCH.

SPECIFICATION forming part of Letters Patent No. 709,939, dated September 30, 1902.

Application filed January 9, 1902. Serial No. 89,081. (No model.)

To all? whom it may concern:

Be it known that I, CLARK F. THAYER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Couches, of which the following is a specification.

The object of this invention is to construct a couch embodying the improvements hereinafter more particularly described.

In the accompanying drawings, Figure l is a transverse vertical sectional view through a couch, illustrating the mode of construction which embodies my invention. Fig. 2 is a fragmental longitudinal section showing the box-loops in the longitudinal supportingbands and the means of attaching the coilsprings thereto, also showing the clips for securing the zigzagcross-wires to thetops of said springs. Fig. 3 is a fragmental top plan View of a couch of my improved construction. Fig. 4 is a fragmental view in perspective, illustrating the intersection of a longitudinal supporting-band with a transverse supporting-band. This figure shows the depressed box-loops in the longitudinal band, also the means for securing the coil-springs to the bands at their intersections. Fig. 5 is ,an under side View of a clip for securing the zigzag cross-wires to the tops of the coil-springs. Fig. 6 is a transverse vertical section through the clip illustrated in the last preceding figure and the wires which it secures together. Fig. 7 is a view illustrating the loop at each end of the zigzag wires for connecting said zigzag wires to the longitudinal side wires of the couch.

In the construction of this couch I provide the usual framework A, within which are supported in any suitable manner the longitudinal bands A and the transverse bands A both preferably constructed from band iron or steel. The transverse bands A. are straight; but those A, extending lengthwise of the couch, are formed with the box-loops A at intervals suitable to receive the transverse bands A which extend across the couch from one side of the frame A to the other, lying in said depressed loops A The spiral springs 13 are mounted on the bands A and A one spring at each point of intersection between the bands. The lower end of the spring is twisted underneath the longitudinal band A and over the transverse band A holding the lower and smaller end of the spring firmly to the bands, and, by reason of the numerous bearing-points of the spring against the bands, supporting the spring securely in an upright position.

Along each side of the couch I provide the longitudinal side wires 0 for holding the upholstered top of the couch outward in a straight line at the sides thereof. Between these side wires C are placed the transverse Wires D, formed zigzag to extend diagonally from one spring to another. At their ends the cross wires D are provided with the downwardly-extending loops D, adapted to loosely surround the longitudinal side wires 0. Two of these wires D are placed between each transverse row of springs and are secured to the tops of thesprings by means of a clip E, formed, preferably, of sheet metal and bent to surround the cross-wire D and the wire of the spring. These clips are provided with three tangstwo on one side and one on the other. The side which has two tangs is caused to engage the cross-wires D, they being straightened for a little distance to receive the clips. The single tang on the other side of the clip engages the spring, which on account of its circular form will not permit it to be held in close contact with the straight portion of the zigzag cross-wires D. When a portion of the couch is depressed, as by a person sitting upon it, the side wires 0 and the springs B at the immediate point where the weight of the person rests are depressed. The loops D of the cross-wires D permit the side wires G to be depressed without straining the connection between the cross-wires and the side wires, as would be the case were they secured rigidly together. The loops D also are made long enough, so that the side wires may have some little movement in said loops and may be twisted at an angle with the plane of the tops of the springs without straining the connection between the crosswires and said longitudinal side wires. The

loops may be made longer that is to say, to extend downward a greater. distance than is indicated in the drawings.

I claim as my invention side Wires for providing a sliding and yield- In a couch, in combination, aframe; spiral ing connection between the cross-wires and 10 springs supported by the frame; longitudithe side Wires. nal side Wires and zigzag cross-wires extend- V 5 ing between alternate opposite springs and CLARK THAYER secured to said springs near the upper ends Witnesses: of the latter, said cross-Wires having loops at J.
