BED-SPRING.

Specification of Letters Patent.

Patented Oct. 24, 1905.

To all whrmt it Wtay concern.-

Be it known that I, THOMAS C. CAREY, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Bed-Springs, of which the following is a specification.

This invention embodies improvements in spring-cushions, and in the preferred adapta tion thereof involves a peculiar construction of bed-spring.

The invention aims to provide a springcushion of this type which is made wholly of metal and which is constructed with reference primarily to secure a maximum degree of simplicity in order that the device may be manufactured as cheaply as possible.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings. in which- Figure 1 is a top plan view of a bed-spring embodying the essential features of the invention. Fig. 2 is a bottom plan View of the invention, a few only of the helical springs of the device being illustrated, as in Fig. 1. Fig. 3 is a sectional view, partially broken away, taken about on the line X X of Fig. 1, looking in the direction of the arrow. Fig. 4C is a broken perspective view of a corner portion of the device embodying the invention, showing more clearly the manner of interlockingthespring-supporting wires. Fig. 5 is a longitudinal sectional view.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The general structure of the spring-cushion which comprises this invention is substantially the same as many of those now in use, which embody a suitable supporting-frame, ordinarily of metal, and a sufficient number of helical springs supported in said frame and adapted to sustain any weight disposed upon by the side rails of the bed between the ends thereof. It is therefore an object of this invention to provide a construction which will cause all weight to be sustained at the corner portions of the bed, thereby obviating likelihood of sagging of the side rails or causing inward and outward movement of the head and foot pieces of the bedstead.

Specifically describing the cushion,the same consists, essentially, of a suitable supportingframe, which for the purpose of this description embodies side rails 1 and end rails 2. The side rails 1 are preferably made of substantial tubing, angle-iron, or the like, the ends of which are received in socket members 3, secured adjacent the end portions of the rails 2. The end rails 2 are preferably made of angle-bars to give the necessary rigidity, and the socket members 3 are secured to one of the wings of said angle-bars by bolts or suitable fastenings, preferably. The side rails 1 of the frame are braced and connected at intervals in the length thereof by means of transverse bars 4:, which bars are preferably of flat metal formation, with the end portions thereof bent at an angle, as shown at 5, and curved, as shown at 6. The curved portions of the bars 4: extend over or receive the side rails, being firmly secured thereto by means of rivets 7 or the like. The provision of the members 5 of the bars 4: disposes said bars some distance below the side rails, as shown most clearly in Fig, 5 of the drawings. The several supporting-bars at are connected by a plurality of braces 8, which are made of flat metal pieces having the end portions thereof turned at an angle and attached to the bars4c at points between said bars. The braces S are arranged longitudinally of the frame or parallel with the side rails .l.

Supporting-bars 4C are utilized to support the usual helical springs 9, customarily used in spring-cushion construction, the. lower extremities of said springs being passed through openings in the bars 4:, and thereby engaged therewith. The edge portions of the bars at are turned upwardly, because of the manner of construction of the end portions thereof, the springs 9 thus bearing against said edge portions in a manner readily noted. The

lower endsbfthespringsQ are thus supported by the bars 4:, the upper ends of said springs, however, being held in proper posi-' 'tion by means of a plurality of longitudinaltransverse supporting strips or wires. The longitudinal supporting-wires 10 are connected to the end rails 2 of the frame by flexible connections in the form of coil-springs 11. The longitudinal \vlres 10, as well as the transverse wires 12, are crimped throughout their length, and the wires 10 are of peculiar for' mation, being doubled at a pointbetweenthe ends thereof to'forin spaceddengthswhich interlock with the'uppermost volute of each of the springs 9 aforesaid. The point at which the wires 10 :are bent upon themselves is engaged by one-end of an adjacent spring 11, as shown at-11,'the extremities-of the wireslO being-bentto form hooks with each of the springs at the=opposite end of 'the frame engaged. The longitudinal wires 10 are thus held taut by the connection 11 aforesaid. However, it will be noted that said wires are 'not rigid, but have a flexible orspring movement under the'usual conditions of serv-' ice. Oneof the spaced elements of eachof the'longitudinal wires 10 passes beneath the uppermost volute of the line of springs .with Wl11Cl1 sa1d Wire cooperates, whereas thead jacent elements pass above said volute,thereby affording a'more positiveinterlocking connection between the springs and. spaced members of the wires 10. The'ends of the springs ll'opp'osite those connected with the wires 10 pass through suitable openings lengthwiseof the end rails 2, affording the necessary connection with these parts. Connecting each end of the end rails 2 1s a longitudinal trusswire '13, connecting the springs 11, which lat ter are also connectedwvith the end railsin the same manner as are the springs with which the wires lO cooperate. The longitu. dinal truss-wires 13 form flexible connections and have the end portions of thetransverse supporting-wires 12 connected therewith,

said wires 12 being hooked around the wires 13 in any suitable manner; The transverse brace-wires cooperate wlththesprings 9, passing beneath and above opposite portions'ofthe uppermost volute of each of the springs;

in transverse alinement therewith. At thesame time the transverse wires 12 pass above the element of the wire 10, which passes over the uppermost volute adjacent the springs 9 and from thence beneaththe adjacent spaced element of such wire, this construction being such that the longitudinal and transverse supporting-wires l0 and 12, respectively, are peculiarly interlocked with each other and at the same time are firmly attached to the uppermost volute of each of the springs 9 with The longitudinal which said wires engage. wires 10 are always under tension because of the provision of the flexible connections 11, a

and the peculiar interlocking connection of said wires 10 and of the wires 12 is such that the springs 9 are held firmly in proper position. 1

It will be noted that certain of the helical springs 9 are disposed above the side rails 1 of the frame of the cushion, and these portions are attached to the said side rails by the same fastenings which secure the curved portions6 of the supporting-bars 4: to said rails 1. The lower extremities of the side springs 9, in other words, are firmly riveted to said side rails, the above producing a substantial reinforced edge-portion for the cushion and causing the whole Weight of the springs to be sustained bythe side rails above mentioned.

The end rails 2 project some distance beyond the side rails lat theextremities thereof, the above constructionbeing such that the ends ofthe rails 2 will rest upon the bedstead at the corners thereof, disposing all strain at this .point instead of along the side rails of said bedstead. The foregoing gives rise to advantages which-have been more clearly pointed out hereinbefore. Transverse wires at the'ends of the cushion-frame are used to reinforce the connections 11, being connected at terminals with end springs and passing a frame comprising sides and ends having the terminals of the latter extending beyond the said sides, flexible connections between the extended terminals of the ends of the frame, helical springs mounted in the frame, and

Y strips engaging said helical springs and connected with the flexible connections.
