SPRING BED BOTTOM.

THOMAS B. CASSELBERRY, OF WILLIAMSPORT, PENNSYLVANIA.
SPRING BED-BOTTOM.
SPECIFICATION forming part of Letters Patent No. 566,496,`dated August 25, 1896.
Application led March l1, 1896. Serial Nox 582,779. (No model.)
To all whom it may concern:
Be it known that I, THOMAS B. CAssEn BERRY, a citizen of the United States, resid ing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Spring Bed-Bottoms and Springs; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.
The present invention has for its object to provide a spring bed-bottom that will possess strength and durability, with the necessary elasticity to form a bedbottom of superior construction, and having advantages that materially enhance its value.
The invention consists in a spring bed-bot tom constructed substantially as shown in the drawings and hereinafter described and claimed.
Figure 1 of the drawings is a top plan view showing a portion of a spring bed-bottom constructed in accordance with my invention; Fig. 2, a detail view showing more clearly the manner of connecting the springs together and to the frame of the bed-bottom; Fig. 3, a detail plan view showing a modification of coupling the springs together at their sides.
In the accompanying drawings, A represents one of the side rails, and B the end rails, of the frame of a bed-bottom. This frame may be a part of the bedstead or separate, in form of a spring-mattress, and I therefore use the term bed-bottom to cover both constructions, as this is immaterial to the essential features of the invention.
The frame, consisting of the side and end rails, may be of any suitable construction found best adapted to the purpose, and has connected thereto a plurality of springs C, formed of spring-wire,which springs loop each other at their sides, as shown at a, or coupled or connected together by a suitable clamp l), as shown in Fig. 3 of the drawings. Each spring is of ,elliptical shape when connected in position, as shown, and the wire is bent at one end of the spring to form a looped tongue c, and at the opposite end t-he wires terminate in hooks d c, The neck c forms a double hook, each one of which has its end turned downward at an acute angle. These hooks are separated from each other a suitable distance, and are united at their outer ends so as to practically form but one, which interlocks positively with the two downwardly-turned free ends d c ofthe next adjoining spring. The hooks of one spring engage with the looped tongue of' the spring adjacent thereto on the same longitudinal line, or lengthwise of the bed-bottom. The looped tongues and the hooks at the opposite ends of each spring provide a very simple and. effective means of connecting them together and gives to the spring a free yielding motion and adds materially to its elasticity when the springs are all connected together to form a spring-bottom.' When the hooks ol e are engaged with the looped tongue c of the adjacent spring, the sides of the spring will be contracted to afford the necessary tension,and the curve of the spring at its sides being long instead of short, as in the springs of ordinary construction, there is less liability of its being impaired by the strain brought thereon by affecting its elastic qualities.
The end springs may be connected to the end rails B` of the frame in any suitable and well-known manner, but preferably by a continuous wire D, secured to the end rails by suitable staples f,'the wire bent throughout its length to form loops g, with which the ends of the springs may engage.
The wire or rod D may have a slight pivotal action to adapt itself to the action of the springs, the staples f forming the bearings therefor, also the pivoting of the wire or rod will enable the loops thereon to be raised up for conveniently engaging the ends of the springs therewith.
The sides of the springs along the side rails of the bed-*bottom may be strengthened by coiled wires E, or any other well-known means may be employed if found desirable. Should any one of the springs become bent from any cause, broken, or otherwise rendered useless, it may be readily and conveniently replaced by a new one without the necessity of any special machinery for the purpose to stretch the springs in fastening them. By the construction of the springs and manner of conroo nesting them with each other a compound spring aotion in the bed-bottom is obtained, each spring acting independently of the other, and consequently the elasticity and IieXibility of the bottom increased.
Having now fully described my invention, what I Claim as new, and desire to secure by Letters Patent, is-
A bed-spring formed from a single piece that is bent into a loop or circle, and which is provided at one end with a double hook c, having,` a space between the two prongs, and
having its outer end turned downward at an acute angle, and at its other end with the two downwardly-turned free ends d, e, which are adapted to oatoh in the double hook of the next adjoining spring, substantially as shown. In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
