IMIEIROVElIDv SPRING- BED-BOTTOM.

The Schedule referred to in these Lettera Patent and making partei the Same.

To all persons to whom these presents shall come:

4Beit known that 'I, GmEoN B. RICHMOND, vof Charlestown, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Spring-Beds, and that the followingl is a full and exact description ot' the same, reference being had to the accompanying plate of drawings.

'.lhe present invention relates to that class of spring bedsin which the slats, at each end, are secured to a trarne' by and through a spring connection, the spring portion of which is ot' a spiral form7 and arranged ditachment to the slat.

In the accompanying plate of drawings my improvements in spring-beds are illustrated,

Figure 1 being a'central longitudinal section of a slat connected to a frame, in accordance with my invention.

Figure 2, a plan View of one end of the arrange` ment of slat springs, shown in iig. 1.'

Figure'7 a transverse vertical section in plane of linea x, fig. 1.

A, in the drawings, represents a frame, constructed yof parallel side, B, and end, C, rails.

l), slats arranged in parallel lines between side rails B, with their ends E connected to the end rails 0 by 'and through an arrangement and construction of parts, as follows:

Y a a, circular apertures, through thickness ot' slats D, one at each end, which apertures are rimmed or turned out on both sides of the slat.

11, spiral orcoiled springs of \vire,.connected and joined'together bya loop,- b, vwhich is a continuation of the wire from the coils of lthe two springs; opposite to'each other the wire, at'the two outer ends of the coils, being extended, terminating 1n a hook,.d,

by which they are hung and connected to flexible or leather pieces, f, connected, in. turn, through hooks,

g, fastened to and in the end rails CV ofthe frame.

The loops b to the springs are. made with a curve l'in the direction of their lengtll,'a`nd by them, connectionis made with the slats, the loops being inserted in their holes a, extending toward their center, resting upon the upper surface, h, and bearing against the' bevel or incline lof theraperture, both of the upper and lower sides ofthe slat, butat points diametricallyy opposite, (see iig.- 1` more. particularly,) the coiled ,springsbeingdirectly under the slat, with the slat resting thereon.

With slats hung to springs in the manner described, the greaterfthe pressure on the slats the more the springs will be coiled, and the firmer the fastening together of the slat and springs will be made, the loops being held to the slats by the bearing of the loop on its upper' side, and its bearing within the aperture against its incline, bothl upper and lower.

Having thus described my invention, lVbat I claim, and desire to secure by Letters Iatent, is-

The spring, consisting ofa continuous wire, doubly coiled at F, and extended beyond the coils into loop b, forming the upper termination of the spring, and entering an opening in the slat, in connection with/ the ends oi' the wire below the coils, being connected to a piece j, as herein set forth.

The above specification of my invention signed by me this 2] st day of April, A. D, 1870. GIDEON B. RICHMOND.
