a COILED-SPRING STRUCTURE.
Application filed February 10, 1922. Serial No; 535,562.
a citizen or" the United States, residing at St. Louis, Missouri, have invented a certain as will enable others skilled in the art to which it appertains to make and use the same. I r I i t This invention relates to coiled spring structures such as are used in bed springs, vehicle seats and the like,
One object of my invention is to provide a coiled spring structure in which thejend coils of the springs of each row are connected together ina novel manner that permits the adjacentsprings of a row to rock or turn freely relatively to each other without binding and without twisting or bend ing the connections between said springs.
Another object is to provide a coiled spring structure in which the means for connecting the springs of a row together and the means for holding the rows of springs in spaced relation are of suchconstruction that they do not form sharp projections on one side of the structure.
And still another object is to provide a coiled spring structure having the desirable characteristics above described that is easy to assemble and inexpensive to manuitac-' ture.
To this end I have devised a coiled spring structure that is made up of a number of parallel rows of coiled springs, an integral portion on the end coil of each spring that is bent around or arranged in interlocking engagement with the end coil of an adjacent spring in the same row, thus causing the springs of a row to be pivotally connected together, and tie wires or rods arranged transversely of said rows and connected to the springs in such a way that they hold the ranged transversely of the rows. abl uthe base coil ,or' end coil of each spring bodied in a coiled spring structure made up of number of'rows of vertically-disposed,
spiral springs A arrangedin parallel rela- 1310111170 eachother, but I wish it to be under-- stood that it is immaterial whether the structureis madeup of cylindrical or conical springs. At one side of the structure the end coils of the springs A are joined together in such a manner that the springs of each row are pivotally connected together and i the respectivejrows are held in spaced relation; by tie wires or rods B that are ar- Prefer-- is provided with a laterally-projecting loop 1 whose terminal portion 1 isbent around the end coil of an adjacent spring of the same row as shown in Figure 1, the terminal P01411011}? of each loop beingdoubled back upon itself and bent downwardly into or below the plane of the coil which said terminal portion embraces, so as to form practically a closed eye on the laterally-projectingportion 1 of one spring that surrounds the end coil of an adjacent spring of the same row Accordingly, the springs of each row will be held spaced apart. but they are free to rock or turn relatively to each other without binding and without bending ortwisting the connections between said springs when a load is imposed on the structure. 7
The tie wires or rods B each consist of a straight piece of heavy wire provided at intervals with upwardly-projecting portions 2, preferably or substantially inverted V" shape in outline, that pass upwardly through the eyes formed by the bent over terminal portions 1 of the laterally-projecting loops 1 on the end coils of the springs.
In assembling the parts of the structure the tie wires 13 are arranged transverselyof or at right angles to the laterally-projecting loops 1 on the end coils of the springs and tangential to the portions of the end coils around which the terminal portions 1 of said loops are adapted to be bent. The terminal portion of each of said loops 1 is then bent around the end coil of an adjacent spring and doubled back over the projec tions 2 on the tie wire, thus causing the tie wire to be locked to two adjacent springs of the same row by means of one of the projections 2 on said tie wire that projects through the bent over terminal portion of the loop. It Will thus be seen that in a structure of the character above described the bent over terminal portions of the laterally-projectingloops l ontheen'd coils of the spring not onlyserve to pivotally connect 7 together the adjacent (springs of each row,
but they also serve to-connect the tie Wires B I to the rows of springs, the tie Wires being I claim as new and desire. to secureby Letters Patentis: a I
