v SPRING-BED.

SPECIFICATION forming part .of Letters Patent No. 280,762, dated July 3, 1883.

Application filed December 14, 1882. (No model.) A

To all whom it may concern:

Be it known that I, WILLIAM PRICE, of the city of Erie, county of Erie, and State of Penn sylvania, have invented certain new and useful Improvements in Bed-Springs; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and the letters of reference marked thereon, which form a part of this specification.

My invention relates to the construction of spring-beds and spiral springs therefor, the manner of attaching the springs to the'framework upon which they are supported, and, further, appliances for attaching the spiral springs to the supporting-frame.

My invention is illustatrated in the accompanying drawings as follows:.

Figure 1 is a vertical View of a section of a bed-bottom, showing the springs attached. Fig.

2 is a side view of the same, showing a portion broken away and parts of it in section. Fig. 3 shows one form of my spring on an enlarged scale, illustrating one way of attaching it to the supporting-frame, and also the construction of the side springs in my improved bed-springs. Fig. 4 shows a portion of one form of a supporting-slat, and also manner of attaching the spring thereto. Fig. 5 shows another way of attaching the spring to the supporting-frame. Fig. 6 shows the under side of a portion of two of the slats composing the supporting-frame, one of them being a lengthwise slat and the other a cross-slat.

In all the figures similar letters refer to the same parts.

The slats E E, &c., G G, 860., forming the frame upon which the springs rest, and to which they are attached, are constructed of strips either of wood or metal, substantially like, in their construction and arrangement, those ordinarily used in spring bed-bottoms, the main point of difierence being the manner of fastening them together and attaching the springs thereto.

Ordinarily in constructing spring-beds the spiral springs are firmly and permanently attached to the supporting-frame, so that they cannot be removed therefrom or changed from one point to another, if desired, (excepting that form of spring which is arranged to be attached directly'to the ordinary bedsteadslat without the intervention of a supporting-frame.) It is obvious that the spiral springs in that portion of a bed where they are subjected to the greatest and most constant use and pressure'in time lose some of .their strength and elasticity. To avoid this I attach my spiral springs vto the supp orting-frame, so that they are easily taken V out and can readily be changed from one point to another when they show signs of weakness and interchanged with stronger ones. This I do in two ways, by the different methods hereinafter shown in screwing the springs to the supporting-frame. In Figs. 2 and 3 I show one of these ways in detail. In constructing the spiral spring I bend the wire of which it is made at the lower end of the spring in a downward direction at right angles with the body of the spring, and cut a screw-thread upon it, as shown at a in Fig. 4, and in the slat upon which it is supported I tap a screwthread, so that I can screw the spring into it, and when it is necessary to put in the crossslats in the frame I make a plain hole in the cross-slat and pass the end of the spring through this hole, thus holding the spring firmly in place, and at the same time holding the parts of the supporting-frame together, yet permitting the easy removal of the spring in case it is deemed desirable so to do. In case I use wooden slats for the frame, I can screw the end of the spring directly into ahole made in the wood itself or into a metal button, 1), (shown in Fig. 6,) which is fixed by rivets or otherwise preferably to the under side of the slat, though it may be on either the lower or upper side of the slat.

In case I use iron slats for the supportingframe, I have them made thick enough at the.

points where the springs are attached to them, or re-enforced, as shown in Figs. 2, 5, and 6, by a metal button riveted thereto or by increasing the thickness of the metal at the point where the screw enters, as shown in Fig. 4. I

also attach my spiral springs to the supporting-frame in another manner by bending the lower end of the spring into a circle small enough to catch the head of a screw, 1), as shown at b b in Fig. 1, the screw being also shown in of the bed I construct in the same shape as spiral springs are ordinarily constructed for spring-beds, as shown in the two lower rows of springs in Fig. 1; but the outside row of springs on either side of the bed I make with an additional loop, or, rather, by extending the wire, after the'completion of the top spiral, directly across the top of the spring, as shown at (6 Figs. 1, 2, and 3, and bending the end thereof downward and under the top spiral, as shown in Fig. 3 at a and along each side of the bed, on the top of the springs and under the loops (6 (6 &c., I place a strip of wood or metal, G, to stiffen the outer row of springs on each side of the bed. (In the section shown in Fig. 1 only one side of the bed-bottom is shown.) To keep the strip G in place in case a metal strip is used, Ibend each end of it downward, as shown in Fig. 2 at g 9, so as to catch the top spiral of the springs at each end of the bed; or the ends of the strip G may, if preferred, be fastened to the ends of the supporting-frame. The springs may also be connected together with loops of wire or chain, if desired. In packing and shipping, also, I can unscrew the springs from the supporting-frame,

' which is held together by them, and pack the springs in one package and the slats composing the frame in another package,,thus greatly 5 economizing the space occupied and facilitating the handling and shipping of them.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The spiral bed-springs A A, &c., in combination with the supporting-frame thereof, said springs being secured in place by means of screw-threads cut on the lower ends thereof and screwed into their supporting-frame, substantially as and for the purpose set forth.

2. The spiral springs A A, &c., constructed with cross-bars a a &c., across the topsthereof, 'in combination with the side bar, G, passing under the cross-bars a (B, &c., and resting upon the tops of said springs, substantially as and for the purpose set forth.

3. The spiral bed-spring A, constructed with a screw-thread on the lower end thereof for attaching it to the supportingframe, as and for the purpose set forth.

4. In combination with the bed-slat C, the

clip or button D, fastened thereto for receiving the screw holding the spiral springs of said bed in place, substantially as and for the pur- 6o pose set forth.

In testimony whereof I have afiixed my sig nature in presence of two witnesses.

WILLIAM PRICE.
