Letters 'Patent No. 94,025, dated Augusti24, 1869.
IMPRovLD SPRING-BED BOTTOM.
The Schedule referred' to in these Letters Patent making part of the same To all persons to whom these presents may come Bc it known that I, EDWARD PERRY, of Hopkinton, of the county of Worcester, and State of Massachusetts, have invented a new and useful Improvement in Spring-Bedsteads; and do hereby declare the same to be fully described in the following specication,
kand represented in the accompanying drawings, of
which- Figure 1 is a top view,
Figure 2, a transverse section, and
Figure 3, a longitudinal section of a spring-bedstead or bed-foundation made in accordance 4with Ymy invention.
The nature of my improvemcntonsists in. an arrangement and combination of two series of V- shaped sp1ings,with a series qf slats, a frame, and` two series of serpentine springs, arranged together substantially in manner as hereinafter explained.
In such drawings- Y A is a rectangular frame, provided with two bars, B B, each of which goes across it transversely, and at its ends each bar B rests in socketed brackets a. a, fixed to the side-bars of the frame.
In each of such bars B there are inserted the lower projecting parts l), of a series of plate-springs C (D,V
85e., each of such springs consisting oi' a strip of sheet-metal, (as steel, for instance,) bent in the se1peu tine form, and in other respects in manner as repre sented.
These springs support a series of thin elastic slats D D, 87o., which are arranged parallel to each other, and at or about at equal distances asunder.
Each slat is sustained by two of the springs, each' of which embraces the slats' inlnauner'as shown at c in figs. 1 and 2.
'lheparts c, which encompass the slats, are connectf ed together, and to the side-bars of the frame A, by
means of a series of wire V-shaped springs, E each of which has a form as shown in top view in g. 1.
These V-shaped springs, arranged between the slats and the bars of the frame A, in manner as exhibited in the drawings, are hinged to or hooked through the parts c of the serpentine springs.
The two external V-spiings of each series of such springs are also so connected with the extreme slats and the side-bars of the frame.
The, V-shaped springs 2 serre not only to' supportthe other springs, as well as .the slats, attheir proper distances asunder, but at the same time allow of the free vertical and lateral motions of the serpentine springs and the slats. The V-shaped springs also operate to support the serpentine springs under the longitudinal movements 'of the slats and serpentinesprings. l
lhe V-shaped springs also allow the slats to move apart from one another, and more or less independently of each other, whereby the bedfoundation is rendered easier and more elastic than is the case when the sla-ts are connected by inelastic strips orbandsA of webbing whichhold the slats so as to prevent them from spreading apart, and also so connect the slats as to cause several of them to operate in supporting a weight when imposed on either of theln.
It is found that my spring-bed, by-the yfreedom c which each slat has to move vertically, or to rock latterally independently of the slat or slats adjacent to it, affords more ease and elasticity to a person when repnsing on it than results from spring-beds whose slats` are connected by strips of webbing.
Consequently I make no claim to connecting the slats by webbing or bands and' to their frame when such slats are supported on springs. Y What I claim as inypinvention, is :is-follows; that 1s- The arrangement and combination of the two series'
