SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Fatent No. 654,707, dated July 31, 1 900.

Application filed July 8, 1899. Serial No. 723,234. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES D. BROU- YETTE, a citizen of'the United States, resid ing at Chicago, in the county of. Cook and State of Illinois, have invented certain new and useful Improvements in Knots for Se-' Figure 1 is a plan of twoupper coils of a spiral-spring bed-bottom, showing my manner of tying the rods. Fig. 2 is an elevation of the same. Fig. 3 is the end of one coil, showing the manner of securing the same to the lateral tie-rods. in the other coil that coacts with a corresponding ofiset or circle in the first coil. Fig. 5 shows a plan of the ring-offset that coacts with the ofiset shown'in Fig. 4: in forming the knot. Fig. 6 is a section of the longitudinal tie-rod, showing its ofiset designed to coact with the several offsets in the coils in forming the knot. Fig. 7 is a plan of sections of the upper coils of the springs, showing an outwardly-projecting offset in one coil and an inwardly-projecting offset in the other coil in lieu of the ofiset and ring shown in Figs. 1 and 5; and Fig. 8 shows the knot formed without the offsets. 7 Similar letters refer to similar parts th ronghout the several views.

In Fig. 1 A represents the top coil of one spring, and A the top coil of the adjacent.

inwardly-projecting offset a in the coil A" and a corresponding outwardly-projecting ring a, in the coil A, in position to lieiinmei Fig. 4 shows the offset diately in or adjacent to the offset in the coil A, so that the offset 12 in the longitudinal tierod B will, with the tie-rod passing over the coil, pass underand beyond both offsets asufficient distance, so that I can form a loop A in the end of the coil and pass this loop under the offset 1) in the tie-rod B and thence up through the space between this offset and the offsets in the coils, as shown in Figs. 1, 2, and 7. To complete the knot or tie, I pass the lateral tie-rod C through the loop A and over the coils and offsets in such a manner that the tie-rod will be held firmlyto place and will hold the loop so that it cannot be drawn back through the ring a, thus forming a firm secure tie or knot between the coils and the tie-rods.

By making the offsets b in the tie-rods B a little more prominent, as indicated at a in Fig. 8, I can dispense with the ring a, as in Fig. 7, and can, in fact, dispense with all offsets'in the coils, as in Fig. 8; but I prefer the useof the ring and offset shown in Fig. 1, as with them I can secure the knot so perfectly as to wholly avert the danger of the coils or tie-rods slipping in either direction.

In Fig. 7 I have shown an offset a upon the coil A in lieu of the ring a, which lies immediately against the outer surface of the coil A, the construction of the knot being otherwise the same as hereinbefore described.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A spiral-spring bed-bottom comprising coiled springs, longitudinal tie-rods having offsets that extend through the respective coils and beyond the adjoining wire of the adjacent coils, a loop formed on each coil to pass between the ofisets on the longitudinal tie-rods and the adjacent spring Y 2 t I I 654,7o'r
