' BED-SIPRINQ.

Application filed April 22,

To all whom it may concern: Be. it known that I, CHARLES H. GAIL, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Bed-Springs, of which the following is a specification. V

V The present invention is designed to provide simple and efficient means "for yieldingly securing together the top coils or convolutions of the upright spiral springs of bed-springs and similar structures, whereby the bed-spring or other structure as a whole will'possess marked resilient or cushioning capabilities.

It is not broadly new to fasten the upper coils of such spiral springs together by means of short helical or coiled springs, but one leading purpose of the present invention is the fastening or securing o'fthe ends of such intermediate or connecting helical springs to the upper coils of the vertical spiral springs in such manner that they cannot shift position under ordinary usage, that the. structure will be wholly noiseless, and that the top coils will not need to be crimped or deformed to hold the helical springs. firmly in place.

A further purpose of the invention is the production or provision of an appliance of this kind having a relatively smooth flat top surface so constructed that the superposed mattress will not sag or be depressed un I duly into or between the several springs of which the structure is composed.

In its preferred embodiment, the inven-' tion takes the form of structure illustrated in the accompanying drawing in the two views of which like reference characters have been used to designate the same parts.

In this drawing:

Figure 1 is a fragmentary or partial plan view of a small portion only of the complete cushion spring but suiiicient of the construction has been shown. for the needs of this patent application; and

Fig. 2 is an enlarged cross-section on line 2-2 of Fig. 1, the parts being viewed in the direction indicated by the arrows.

The improved and novel bed-spring, the principles of construction of which may be advantageously employed in many other relations where cushion structures of this general type are desired, comprises, as will be readily seen from the drawing, a plurality Specification of Letters Patent. Patented Aug. 9, 1921.

of suitably-supported, vertical, aced spiral shown.

It 1s, of course, necessary toitie or secure these top coils together to Inaintainf the springs at all times in propejrposition nd this is preferably done by" employing elastic or expansible and contractible helical springs arranged horizontally between such upper-' most coils, thus giving the latter adequate manent displacement.

To this end, the upper coil of each spiral spring, except the marginal or border ones;-

not illustrated, is connected to thecorre-f sponding coils of the four adj acent springs by that number of horizontal, helical springs; 12, 13,- 14 and 15 arranged ninety degrees apart with the springs 12 and'lidiametrifreedom of movement Without undue or percally opposite one another and the

remaining springs

13 and 15 similarly disposed;

The loops 16 ofthe springs 12 and 14,

formed by properly bending the end portions of the wires of which'the springs are made,

project inwardly over and rest on the wire forming the top coil of the spiral spring under consideration, and such loops or eyes] are-securely fastened 1n position by a cross-.

wire 17 eixtendedacross themiddle of the top coll, each end'being bent to pass; down through the loop at 1 8 inside of the top coil, I

then outwardly at 19 beneath the wire constituting such top coil, then upwardly at 20 through the loop outside of. the top coil, then over one side of the loop at 21,. and then down over the side of such portion of the loop. at 22.

By this simple means, these ends of the two oppositely-disposed springs are so Se:

curely and firmly fastened to the spiralsp-ring that unintentional dislodgment or displacement is impossible even though the wire forming the top coil is not crimped at these points of attachment.

It will be observed that the end of eachv helical spring is held securely against the.

upwardly-extended part 20 of the fastening wire and that the latter is firmly held against v t the outer side of the top coil by reason of the section 18 of the wire which bears againstv the end of the loop, whereby the loop 1s very same spiral-spring by means of similarly bent ends of another Wire 23 crossing such top coil at right angles to and either above or below the wire 3.

The other ends oi each of these four helical springs are in like fashion secured to the coils of the four adjoining or neighboring spiral-springs, it being understood that each ofthe latter is connected to four other springs in the manner indicated.

The crossing wires 1? and 23 of each up right spring not only afford means for securing or tying the helical springs in position but they also act as mattress supporting means preventing the mattress from unduly sagging into the spring.

'The improved and novel structure illustrated and described affords a desirable cushion or bed-spring with suitable resilient and elastic capabilities and functions,

' which is comparatively simple in structure,

the elements of which may be quickly and readily placed in position and assembled, and which is free from noise when 1n use,

the helical springs being so immovably clamped. to the spiral-springs that slipping or sliding out of place is out of the question.

Many minor mechanical changes may be incorporated in the, construction detailed above and still the latter would embody the invention as presented in the appended claims, because the invention is susceptible of embodiment in a variety of forms all containing the'i undamental principles of structure and function on which the invention rests.

'1. In a bed-spring, the combination of an upright spiral-spring, a horizontal helicalspring having an end loop overlying the top coil of said spiral-spring, and a wire having a portion bent down through said loop inside of said top coil, then passing beneath the wire forming said top coil, then extending upwardly through said loop, then over the top of one side of said loop, and then down over the side of the loop.

2. In a bed-spring, the combination of an upright spiral-spring, a horizontal helicalspring having an end loop overlying the top coil of said spiral-spring, and a Wire extended across said top coil and having a portion bent down through said loop inside of said top coil, then passing beneath the wire forming said top coil, then extending upwardly through said loop outside of SELlCl top coil, then over the top of one side of said loop, and then down over the side of said side of theloop.

3. In a bed-spring, the combination of an upright spiral-spring, a pair of horizontal helical-springs arrange-a outside of and at diametrically opposite points or" the top coil of saio spiral-spring, each of saidhelicalsprings having. an end loop overlying the wire rormin said to coil and a wire extended across said top coil between said upright spiralspring, a horizontal helical-- spring having an end loop extended across the wire forming the top coil of said spiralspring, and a fastening wire projecting through said loop inside of said top coil, then across the wire forming said top coil on the side opposite said loop, then through said loop outside of said top coil, and then aroune the wire forming one side of said loop.
