Description

UNITED, STATES PATENT OFFIcE.
LUKE H. WHITNEY, OF CAMBRIDGE, MASSACHUSETTS.
SPRING BED-BOTTOM.
SPECIFICATION forming part of Letters Patent No. 229,023, dated June 22, 1880.
' Application filed March 19, 1880. (No model.)
To all whom it may conccmf Be it known that I, LUKE H. WHITNEY, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Spring Bed-Bottoms; and 1 do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 an end view, and Fig. 3 a side elevation, of abed bottom or section thereof provided with my invention, which consists in the combination of a series of spring-sustaining bars with a set of cross supportin g-bars by clasps or devices constructed and applied so as to enable each springsustaining bar of the series to be moved either longitudinally or laterally, or both longitudinally and laterally, on the cross supportingbars, and in the meantime be held in connection'therewith.
The object of the invention is to enable the section or bed-bottom to be adjusted in length or width, or in both length and width, to a bedstead, as occasion may require.
To this end I employ for supporting the conico-helical springs A a series of longitudinal bars, I), each of which has fixed to it aset of springs, as shown. These bars I impose on two or more cross-bars, O, bent up at their ends, as shown, and I connect each of the longitudinal bars to the cross-bar at their crossing by means of a c1asp,D,arranged obliquely on them, in manner as shown.
A side view of one of such clasps is shown in Fig. 4, wherein the clasp is represented as composed of two wires, a b, hinged together. The lower of them, near its free end, is bent up at a right angle, and is provided with a screw, 0, to go through an eye, 01, formed in the upper wire, a nut, 0, being applied to each screw.
On loosening the nuts of the clasps of each longitudinal bar it may be moved sidewise or and the clasps arranged obliq uely, as described,
so as to enable each of the spring-carrying bars to be adjusted longitudinally or laterally on the cross-bars, as occasion may require, and in the meantime be in connection with the said cross-bars, all being substantially as set forth.
LUKE H. WHITNEY.
