SPRlNG-BED.

SPECIFICATION forming part of Letters Patent No. 264,212, dated September 12, 1882. Application iled July 29, 1.882. (No model.)

To all whom it may concern:

Be it known that we, JAMES AINSLIE and RoBEn'rAINsLIE, citizens of the United States, residingatBi-ooklyn, Kings county, New York, haveinvented new and useful ImprovementsA in Spring-Beds,of which the following is a specitication.

This invention relates to thatclass of springbeds which are composed of a series ot' longitudinal and transverse metal strips or slats united together and supporting volute or spiral springs which are connected at their larger ends by a system of chains or links. Such class of beds are capable of being rolled into cylindrical form when not in use; but in some beds of this character theeXtent to which they can be rolled or folded is limited by the inherent elasticity or iexibility of the transverse metal strips or slats. In one. instance these transverse metal strips or stays have been composed of a series of links provided at their ends with eyes loosely encircling and engaging pintlcs secured to the opposite ends of clips, each of such clips being rigidly attached to one of the longitudinal metal strips composing the bed, and provided with projecting ears at its ends, between which the aforesaid pintles are rigidly secured to engage the eyes on the links composing the cross-stays, as above stated. This construction of bedbottom permits the same to be rolled or folded, and in this respect is very desirable; but, owing to the peculiar construction of the aforesaid clips, the necessity of providing both ends ot' each link with an eye to loosely engage pintles on the clips, and the rigid attachment of the longitudinal metal strips or slats centrally 'to such clips, the cost of manufacturing the beds involves such expense as to preclude extensive sale ofv the beds. Besides this, the peculiar arrangement of the parts necessitates the clips being made of considerable length for the purposes ot' receiving and supporting the longitudinal metal strips or slats, and obviously this prevents, to a considerable extent, the rolling of the bed into the least compass and into the smallest cylindrical form 5 and, further, the excessive strain brought on the eyes ot' the links and the pintles ofthe clips, which must necessarily be made small, materially weakens the structure ot' the bed and renders it'eXceedin gl y liable to become broken and disarran ged.

The objects of our invention are to overcome such objection, to provide a bed which possesses substantial and strong qualities, to permit the bed to be rolled into the least possible compass, and to enable it to be cheaply manu factured andhence save considerable expense to the public. These objects we accomplish bythe construction of spring-bed illustrated in the accompanying drawings, in which- Figure lis a top or plan view ot' our improved spring-bed spread open. Fig. 2 is an end view ot' the same rolled up, and Fig. 3V is a detached enlarged view clearly showing the form of hinge-joint used to couple or connect the adjacent ends ot' the sections composing the transverse metal strips or slats.

TheletterA refers to thelongitudinal springmetal slats or strips, which are arranged parallel with each other at suitable distances apart, and riveted or otherwise secured at their ends to the transverse strips B, a third transverse strip being also attached to the middle ot the longitudinal strips.

C indicates the volute wire sprin gs, which are attached, as usual, to the longitudinal strips, and connected together by means of cha-ins D, which, when the bed is open, lie in the outlines of diamond-shaped tigures, as illustrated in Fig. l. The outer longitudinal strips ot' the series are further connected with the end strips at the corners ot' the frame by brace-links E, and upon each line ot' springs at the two sides of the bed are secured the upper side strips, F, which prevent the bed from sagging at its sides.

In carrying out our invention we form each one ot the transverse metal strips ot' any desired number of sections, and these sections wc connect together at their ends by butthinges G, so as to t'orm acompletejointed metal strip. Each of these hinges is composed of two leaves, l, united by a connectingpintle, 2, which serves as a means for articulating the leaves together, and each leaf is rigidly attached to the upper side of one end of each section composing the transverse metal strips or stays. 1t will be observed that this mode of joining the sections serves to bring their ad jacent ends in close juxtaposition, and theretore the bed can be rolled into the very least possible compass;V and, further, the en tire structure is materiallystrengthened by such IOO mode of hinging the sections. A further function resulting from this mode of constructin g the bed is that when the same is opened the adjacent ends of the sections abut against each other, thereby acting as stops and in a measure limiting the movement of the parts in opening the bed. These hinges allow the bed to be spread out, as shown in Fig. l, or admit of it being folded or rolled up, as in Fig. 2. They will also admit of one portion of the bed being readily raised-or rolled while the other lies in a spread condition upon the bedstead-slats or other support for the spring-bed.

It will be observed that each transverse strip has a hinge between each pair of longitudinal strips, and hence the bed can be folded into quite a small compass.

Any suitable fastening devices can be provided atthe terminals of the transverse stripsas, for example, a strap could have an eye at one end and a hook or button at the other, whereby after the bed has been rolled up, as in Fig. 2, the meeting ends of the transverse straps can be connected together, and thus render the bed convenient for shipment or storage.

The transverse strips need not necessarily be made of very thin spring metal, as heretofore, since even if made quite stout the bed can be rolled up into the form shown in Fig. l, or otherwise folded, as already specified.

It will be seen that the vol nte springs in no Wise interfere with the folding up of the bed into compact form, and that While the hinges admit of the bed being rolled up much more readily than heretofore they also permit the bed to be made considerably stronger.

What we claim is As an improved article of manufacture, a spring-bed consisting of longitudinal and transverse metal strips or stays supporting connected volute or spiral springs, each of said transverse strips or stays being composed of sections having their adjacent ends rigidly fixed to the leaves of' butt-hinges, and thus brought into closejuxtaposition, in the manner and for the objects herein set forth.

In testimony whereof we have hereunto set our hands in the presence ot' two subscribing witnesses.
