IMPROVEMENT IN SPRING BvED-BOTTOMS. v
Specification forming part of Letters Patent No. 159,086, dated January 26, 1875; application filed September 26, 1874.
To all whom it may concern:
Be it known that we, J osEPH FOWLER, of the city, county, and State of New York, and JOHN R. DEWAR, of Bergen, Hudson county, New Jersey, have invented a new and Improved Spring Bed-Bottom, of which the followlng is a specification:
Our invention is an improvement in the class of bed-bottoms which are suspended from the bedstcad or frame by means of elastic cords or bands.
The improvement relates to connecting the slats of the bed-bottom in pairs or sections, and also preventing endwise movement of the same, by means of notched blocks, which engage or lock with the springs that support the bed, as hereinafter described. A
In the drawing, Figure l is a vertical longitudinal section 5 and Fig. 2, a similar crosssection, the respective lines thereof' being indicated by a :v and y y. Fig. 3 is a detail perspective view of a fragment of -one of the sections of the bed-bottom.
The bed-bottom is suspended from t-he end walls of a ships berth, or from the head and foot board of the rectangular bedstead or trame A, by the spiral springs O and the crossbars D. The means of attachment or connection of the springs to said wall or frame conslst of pins or nails B inserted through top 'A bar, Gr, which latter serves in some measure as a support therefor (by friction or binding action) with the vertical wall, and also prevents the springs abrading it as they move up and down under varyin g weight or pressure. lhe springs O are attached to the dat bars D 1n such a manner that the latter are prevented from turning on their axis. The ends of the slats composing the bed-bottom proper are attached 1n pairs, or series of two or more, to
transverse blocks or short bars F, which are cut out at their ends a, to adapt them to partly embrace or t around the springs, as clearly shown in Fig. 2.
This construction and arrangement serves to prevent both lateral and endwise movement of the Slat-sections. There is, therefore, no friction between the ends of the independent Slat-sections E F and the adjacent end wall of the bedstead or berth, so that there is complete freedom of movement up and down without creaking or other disagreeable sound that would result from contact of the parts. The connection of the slats in pairs adapts them for being handled more rapidly and conveniently, and each of them is practically stili'- ened or strengthened by its neighbor, so that it will individually sustain greater pressure than when used alone or not paired. Yet the elasticity of the slat-sections individually, or of the bed-bottomas a whole, is not in the least impaired.
Our invention, therefore, includes the advantages resulting from prevention of endwise motion of the slats, and combining them in sections by the same means to wit, the notched bars F.
The bars F F, having notched ends a., and the slats E E, in combination with the springs U and suspended bars D, as shown and described, to operate as specified.
