BED-SPRING. l l

Patented Feb. 2o, 1906.

Application filed January 19, 1905. Serial No. 241,774.

`To @ZZ whom it may concern.-

Be it known that I, BENJAMIN F. LINDS- LEY, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Bed-Spring, of which the following is a specification. i

My invention relates to a bed-spring composed of a series of conical coiled springs suspended in vertical series, in combination with a series of coiled expansion or compression springs attached to each end of the frame on one end with the opposite ends secured alternately to a bar and a chain which is used `to form part of the surface of the bed-spring.

In the construction of the ordinary bedspring now in use no provision is made with reference to the fact that one or more persons or persons of different weight Will occupythe bed, the result being'that the tension of the springs is either too weak or too strong to give the necessary elasticity, which affords the comfort and rest the spring isdesigned to obtain;

The obj ect of my invention is to provide a meansof constructing a bed-spring that will retain its elasticity uniformly when subjected to increased or decreased weight and to afford facilities for maintaining the elasticity when the wei ht is unevenly distributed on either side of t e spring.

A further object is to construct a spring in such a manner as to connect the spring and chain to the frame, so as to give free movements to all of the parts formingthe surface and at the same time retaining them in their proper positions.

' I attain these and other objects by the construction shown and illustrated in the accompanying drawings, in which- Figure 1 is a topplan view of my device, showing the conical and coiled springs attached, in combination with the chain to the frame which forms the-surface of the bedsprng. Fig. 2 i's a side-view of Fig. 1, with dotted lines B B representing the center of the frame, showing the bar upon which the conical springs are mounted and broken sections of the side rail. Fig. 3 is a top and side view of the linked brace-bar, showing method of tying and retaining the spring -bars in place. Fig. 4 is a bottom plan view of one conical spring, showing loop in spring with the free end hooked therein, forming a complete circle. Fig. 45 is a, side plan view of one to the coil-springs 6.

of the coiled sprin s. Fig; 6 is a view of a broken section of t e chain used to form the surface of the bed-spring. Fig. 7 is a side plan view of one of the conical springs, showing means of fastening the spring to the bar, whereby free movement is given to the spring. Fig. 8 is a side view of one of the side rails.

Similar figures of reference refer to similar parts throughout the several views.

In constructing my device I provide 4a frame consisting of end pieces 1 and side rails 2. The end pieces are notched, permitting them to rest on the end and side rails of the bed when used in conjunction with an ordinary iron bed. Bars 3 are securely fastened to the end pieces 1 ,leaving part of the bars projecting inwardly. Apertures 4 are provided to receive the looped ends 5 of the coiled expansion or compression spring 6. Depending bars 7, having apertures in each end, are attached to the opposite end or loop of the coiled spring 6. ed to support the conical springs 8. T e bars are formed so as to leave the bottom of .the springs projecting more or less above the plane of frame. One end 9 of the conical spring is formed L-shaped and inserted in a suitable aperture 10, provided in the bar 7. It will be noted that this method of fastening the springs to the bar retains the springs securely and at \the same time permits free movement of the connecting parts, obv'iatin undue friction, which aHects theelasticity o the bed-spring. A suitable linked chain 11, preferably of kind shown in Fig. 6, is attached A'alternately to the coil-springs 6a through the medium of the rings 12. are connected to the ends of the'chains 11 and the rings 12, which in turnare connected Chains 11El in broken sections are connected to the conical 'springs and the auxiliary chains 13, forming part of the surface of the bed-spring. Chains 13a are provided to complete the surface of the bed-spring. The ends of llware connected to the top of each conical spring' at points diametrically opposed to each other and serve to keepthe spring in proper position and counteract the tendency of spring to move endwise.

-Side bars 14 are connected to the end pieces 11 of the frame through the medium of the coil-springs 15, which connect them under tension for the purpose of preventing any The bars 7 are adatj Auxiliary chains 13 the broken chain -mounte of novel brace 18, Which is composed of a vint tendency of the spring to move sidevvise when the springs are under pressure. Short sections 16 of alinked chain are connected to the top ofthe conical springs at right angles to the chains 11 and 11a \to prevent side or lateral motion. The end sections 17 of the chain 16 are connected to the side bars 14.

'In 'order to hold the bars 7 in proper alinement u on Which the conical' springs are I connectthem together by means ment of eaeh othe:` and of the coiled springs attached to the end pieces. The end springs support a predetermined amount of the Weight, and when theWeight is increased two y conical springs supportthe additional Weight without affecting the elasticity of the bedsprings. The entire bed-s ring is suspended from the end pieces bytlie bars and chain, and all parts havev free and' independent movement in relation to each other.

Slight changes and modifications can be made Without deviating from the principal involved lin my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

' y1. In a bed-spring the combination of a frame having a series of bars suspended from end pieces, a series of conical springs mounted on said bars, coil-s rings securely attached to the end pieces, c ains connected to said s rings substantially as and for the'purp'ose escrlbed. Y

2. In 'a bed-s ring composed of a frame having suitable Bars suspended therefrom, a. series of-coile'd springs attached't'o'said frame, chains attached to said coiled springs through thel medium 4of suitable rings a series of short; sections of chain connecting the top of the conical springs at points diametrically opposed to each other with the ends of said sections secured to suitable side bars.

3. The combination of a frame having deending tubular side rails, With end pieces i aving their corners notched-and 'adapted to iitthe end and side railsof the bed, side bars connected tothe end pieces under tension through the medium of coiled springs.

4. Ina bed-spring composed of a frame having suitable bars attached thereto and projecting inwardly with apertures provided therein and adapted to receive the loo ed end of the coiled springs, rings attache to the opposite looped ends of the coiled springs, c ains connected thereto and adapted to form part of the surface of the bed-springs, said chainst and springs being adapted -to maintain a'predetermined Weight, a series of bars suspended from the end pieces and supported by coiled springs attached thereto, a series of conical springs adapted to be supported vertically from said bars whereby additional Weight is sustained Without affecting the elasticity of the bed-spring.

5. In a bed-spring the combination of a framehaving a series of coiled springs attached horizontally to the end pieces thereof,

said springs supporting a series of bars, a se, ries of conical springs mounted thereon, a linked brace connecting said bars together whereby said springs are kept in proper alinement permitting independent movement substantially as and for the purpose described.

6. In a bed-spring the combination of a frame havin springsattac ed thereto, a series of bars suspended from said frame, chains supported by said coiled springs, a series of conical s rings supported by said bars, side bars attac ed to the end piece of the frame under tension and adapted to prevent lateral motion, chains attached to alternate coiled s rings forming Ya part of the surface of the be -spring 7. In a bed-spring the combination of a `frame having a series of coiled springs attached thereto, a series ,of bars sus ended therefrom, conical s rings supported ysaid bars, chains secure ,to said coiled springs, side bars secured to sections of said chains in such a manner as to give free and inde endent movementto all parts substantially as -and for the urpose described.
