IMPROVEMENT IN BEiD'BOTi'OWlS.
Specification forming part of Letters Patent No. 131,187, dated September 10, 1872.
SPECIFICATION.
To all whom it may concern:
Be it known that we, NORMAN SMITH and EDWIN S. FrELD,both of Hartford, in the counthereon.
Like letters in the figures indicate the same parts.
Our invention consists in a new construction and arrangement of wire links and springs to form a spring bed-bottom. It also consists in certain arrangements of the frame which permits the bed-bottom to be relaxed and taken olf, so that it can be rolled into a small compass for transportation.
In the accompanying drawing, Figure l is a top view of our improved bed-bottom'and frame. Fig. 2 is a side view of the same.
a a a, &c., are links of steel wire, with hooks at the ends, which are attached to the corners of the four-sided pieces b Z b, Src. The pieces b are likewise made of steel wire, and are bent into the form shown in the drawing, having a ring, c, at one end, then a twist of the wire, and then the four sides forming the angles for attaching the links a. The extreme ends of the wire, forming two sides of the parallelogram b, are bent into hooks al cl, which hook into the end ring c of the adjacent piece, as shown in Fig. l. At the head and foot of the bed are steel spiral springs s, arranged in pairs to draw diagonallyr from the angles of the parallelograms b, and attached to the head and foot bars e and f by the hooks g. This arrangement of springs makes a lateral resistance, and prevents the whole bed-bottom from being drawn toward any point where a weight rests. At the sides of the bed are the straight links h h, attached to the rings c, and a corresponding loose ring, c', at the hook end of the pieces b. To the rings c c at the sides of the bed, are also attached the spiral springs s s', which are fastened to the sides of the frame by the hooks g', in a similar man ner to the head and foot springs. The frame is connected together at the corners by the metallic connections @I and j, as shown in the drawing. At one end of the frame a set-screw, la, passes through the metallic corner piece, and acts upon the end of the side bar l in such a manner as to separate the head and foot bars, and stretch the fabric forming the bedbottom.
Ourimproved bed-bottom canbe easily taken apart, when desired, by relaxing the fabric by turning the screws 7c and unhooking the springs s s from the hooks g g. The bed can then be folded up into small compass, and the frame taken apart for transportation. To re place the bed, the springs are reattached to their respective hooks, and the fabric again extended by means ofthe screws lc.
The metallic connecting pieces ij at the corners of the frame are made so as to embrace the top and bottom and inside of the ends of the bars ef l l, so that the stretching of the fabric upon the frame firmly draws all the parts together, without being connected or held together by the screws, bolts, or other fastening, than merely laying the ends of the side and end pieces into the castings lj. The insides of these pieces rest against the sides, and the ends abut firmly against the metallic corners so that no movement can take place when the bed is drawn to its proper tension.
Claims.
What we claim as our invention is 1. The combination of the pieces b with the links a and springs s to form a bedbottom, when arranged substantially as described.
2. The combination ofthe screws k, the bar e and its hook g, with a spring fabric of the construction described, for the. purpose set forth.
3. The metallic corner pieces ij, when c0nstructed so as to embrace the top, bottom, inside, and ends of the frame pieces ef l l, and dispense with the use of screws or bolts, subA stantially as described.
