IMPROVEMENT IN SPRING-SEATS AND BEDS.

Specification forming part of Letters Patent No. 129,098, dated July 16, 1872.

To all whom it may concern:

Be it known that I, JAMES P. CHAMBERLIN, of North Abington, Plymouth county, State of Massachusetts, have invented a new and useful Improvement in Spring-Seats and Beds; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying plate of drawing.

' This invention relates particularly to a spring-seat or bed, for which Letters Patent, dated December 19, 1871, and numbered 121,- 990, were issued to me. The invention consists in a novel construction ot' the spring and of the application to it of a strip of webbing, as hereinafter particularly described.

In the accompanying plate of drawing my improvements in spring-seats and beds are illustrated- Figure 1 being a plan view; Fig. 2, a longitudinal section in line'x Fig. l, Fig. 3, a cross section in line e y, Fig. 1.

A in the drawing Aipresents a spring such as described in the tters Patent referred to. This spring A is m de of two bands, a, of metal, one within the other, and contiguous to and in contact with each other 5 C, a band or strip of woven material connecting together the several coils of the spring A. The Strip C extends from one end of the spring to the other, and where it intersects a coil of the Spring it is placed and laid in and betweenY vand by their prongs they pass through the webbing C, securing the same, when the prongs are doubled under the inner band a,

to the bands a; B, a rail to which the spring A is secured. This rail B is in two parts, c and d, and between the two parts the spring A by its separate coils is placed, lying in grooves f of the upper part of the rail. The two parts c and d are now secured together by screws, fastening thereby the spring A in place, and the web-strip C is at each end nailed or otherwise secured under tension to the rail B, the nails or pins being lettered h.

Having thus described my invention I will state my claim as follows:

The spring A made of two or more bands, a, webbing-strip C, clasps b, and divided rail B, all in combination as described, for the purposes specified.
