SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 511,691, dated December 26, 1893.

Application filed April 13, 1891. Serial No. 888,935. (No model.)

tains to make and use the same, reference being had tothe accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to spring beds the object being to construct such an article of hour glass springs in such a manner, as far as practical, as to obtain a perfect integrality of the entire structure, the details of all of which will be hereinafter fully described and the elements and combinations for which special novelty is claimed will be hereinafter specified.

In the accompanying drawings, Figure 1 is a plan of the device in which figure, for convenience of illustration, the springs are proportionally too large and a fewer number used than the usual custom in manufacture. Figi2 is a plan view of a portion of one of the springs more clearly showing the manner of bending the free end of the coil around the top coil and extending it. Fig. 3 is a side elevation partly in section showing the arrangement and connection of the springs. Fig. 4: is a portion of a spring and a transverse rod showing the upwardly bent portion of the spring and the transverse rod shown near 3 in Fig. 3.

In the drawings like reference marks are employed in the designation of corresponding elements of construct-ion in all the views.

1 is the frame of wire or other suitable material. A joint 2 is employed to connect the free ends of the wire when said frame is of such. Cross bars 3 extend transversely or longitudinally of the frame and for a purpose presently to be mentioned have kinks or bends 4 therein at intervals. These bars 3 are secured to the frame 1 at the desired points and extend in the construction of the device shown, in a direction parallel to the bars of the frame 1, other than the ones to which they are secured.

The springs 5 are in the usual form, and have their ends looped around or otherwise securely fastened to the uppermost coil, he loop 6 being preferable and the said end is extended for a sufficient distance beyond said loop in a horizontal plane, (otherwise the plane of the top of the spring,) and a hooked or turned back portion 7 formed on the end thereof, the free end of said hook being turned downwardly to prevent a disruption of the hereinafter specified engagement of said hook 7 with the bar 3 and the spring 5. At its point of contact with one of the bars 3 the top coil of the spring 5 is bent downwardly at approximately an angle of fortyfive degrees. Said bend is numbered 8 in the drawings.

In connecting the springs the hook 7, bar 3 and loop 8 are engaged in the manner shown in Figs. 3 and 4, the bar3 being placed at the bending point of the spring resting under the uppermost coil of said spring as shown, the kinks 4 contacting with the spring at the bending points and preventing the said spring from slipping on the bar, and the loop 7 is engaged by hooking it over the wire 3 centrally between the two kinks and passing the end through between the

wires

3 and 8 and giving it a movement downwardly so as to bring the downwardly bent end 9 into the position shown in Fig. 3.

As shown in Fig. 1 the outside hooks 7 are hooked over the frame 1 and down the center of the bed the springs are consequently so set that two loops 8 are contiguous. To connect the two middle rows together, wires 10 are used which have loops? and downward extensions 9 thereon at each end functionally the same as the loops and extensions hereinbefore described as belonging to the extensions 11 of the springs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In a spring bed, the combination of a frame, the springs each having its end coils provided with the bends 8, extending toward the longitudinal center of the bed and away from the axis of the spring, the tie rods extending of said bend 8, and is bent down at the outer [0 along the inner sides of the end coils of the side. of said bend, substantially as described. springs and having the kinks fitting the coils In testimony whereof I hereunto affix my at the ends of the bends, and the lateral arms signatu re in presence of two witnesses. 5 connecting the end coils of the springs, each a T arm passing over the bend of the adjacent (A BUS FLINT end coil and over the tie rod, and having the \Vitnessesz, hook engaging the tie rod, the free end of A.
