ANDREW J. LYTLE, OF HILLSBOROUGH, OHIO.

PILLOW.

SPECIFICATION forming part of Letters Patent No. 484,441, dated October 18, 1892.

Application filed February 2, 1892. Serial No. 420,099- (No model.)

To all whom it may concern:

Be it known that 1, ANDREW J AOKSON LY- TLE, a citizen of the United States of America, residing at Hillsborough, in the county of Highland and State of Ohio,have invented a new and useful Pillow, of which the following is a specification.

My invention relates to improvements in spring-pillows; and the object-is to provide an article of the kind named which will be comfortable, delightfully resilient and yielding, shapely, and durable.

I have hereinafter fully described the construction, and have also particularly pointed out and distinctly made claim to the invention, as required by the statute.

In the accompanying drawings, Figurel is a perspective view of the skeleton frame of the pillow, the covering over the inner set of springs being shown broken away. Fig. 2 is a longitudinal section. Fig. 3 is a transverse section on the line a; to of Fig. 2. Fig. 4 is a view of a modified form of spring wherein, instead of the coil-spring, a fiat spring is shown having the portions near the ends crimped to give the required resiliency.

A designates a frame, preferably of a rectangular form and oblong. This frame consists of a metal bar or wire of such size as to provide the proper rigidity and at the same time give a slight resilient function when pressure is applied on the pillow. To retain the frame in due relation at the sides and to return it to normal position after the pressure has been removed or released, a crossspring 1 is arranged between the side bars of the frame and has its ends secured thereto, as shown in the drawings. This cross-spring prevents the frame from being unduly expanded when pressure is put on the pillow and at the same time tends to force the other springs to normal position by its action on the frame. Its use also dispenses with vertically-arranged spiral springs to assist in expanding the pillow.

B B designate, respectively, top and bot tom springs arched or curved, as shown, and having their ends rigidly secured to the side bars of the metal frame at 2. These springs in their relative arrangement form ellipses, the middle ones being highest at the center and the others gradually decreasing in height, so as to make the pillow tapering from the center to the ends. The springs are secured to the side bars of the frame with their ends in a1- ternation, as shown, and this is my preferred manner of construction; but, as hereinafter specified, if a flat spring, with crimped end portions, is used the springs may be a fullelliptical spring.

0 O designate longitudinally arranged springs at top and bottom of the pillow, having their ends fastened to the end bars of the frame and intersecting the other springs. The arrangement of these respective springs, it will be perceived, form a pillow-frame which is ellipticalin both directions. To prevent any noise at the intersections or crossings of the springs, I put a covering 3 over the inner set of springsand secure it over the frame, and over the whole frame and springs an outer covering 4 is secured, substantially as shown. These respective coverings may be of any suitable material usually employed for such purposes. The outer covering may be padded to make the surface yielding and pleasant to the touch of the person and to prevent the springs from being felt when pressed together. By rigidly fastening the ends of the springs to the frame with the ends of the springs directed in the direction of the curve they are held so that they always return to the upper limit when the pressure is removed, and the expansion of the pillow thus insured.

Having thus described my invention, what I claim, and desire to secure byLetters Patent, is

1. In a spring-pillow, the combination of a rectangular frame, reversely arranged top and bottom semielliptical springs, a covering over said springs, longitudinally arranged top and bottom semielliptical springs, and an outer covering.

2. In a spring-pillow, the combination of a rectangular frame, a crossspring having its ends secured to the side-bars of the frame, top and bottom semielliptical springs having their ends secured to the side bars of the frame, a covering over said springs, longitudinally-arranged top and bottom semielliptical springs over the said covering, and a covering over the Whole frame and springs.

In witness whereof I have hereto set my hand in the presence of two attesting witnesses.
