citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new. and useful Improvement in Helical Springs, of which the followin is a specification, this ,a plication beinga ivision of my applicati im, Serial'No. 261,673, filedMay 22, 1905.
My invention relates to helical springs 1 and it has for its object-to provide a device of this characterwhich shall serve to resilientl 5- cordance with my invention, and Fig. 2 1s a longitudinal sectional View of thespring shown oppose pressure exerted'against any and a1 portions of its periphery, as well as against its ends or against pressure exerted in either of said directions alone. My invention is primarily designed for. utilization .asa cushion'device between an internal boss .or core and the inner cylindrical wall of a'surrounding chamber; but it is my intention to have-"it utilized in an relation where its' special structure and ctional characteristics may render i a In the accompanying drawings,- an end-view o a spring constructe in acin Big. 1 and two cooperating members.
As will be seen by reference to the draw-' ings, each turn of the helical s ring 1 is offset from the. adjacent 'turns,'so that the centers of curvature of the several turns are out of alinement with each other, and if a cylin drical core 2 of'the maximum diameter to fit within the spring is introduced: no one of the turns will engage such core for ,any considercent turns will engage the core s ment of turns were employed, and therefore the distribution of the cushion efl'ect is the t correspond ing points or port ons. While .he relation of the several-turns each to the )ther may be varied from that hereshown, the general arranement here indicated will give the best resu ts, sincethe locus of the centers of ourvature of the several turns or convolutions constitutes a helix,- and therefore the points of contact of the interior of the spring with the core and of the exterior of the spring with a .cylindrical chamber 3, in which it may be located, will be distributed more uniformly than would be the case if a different arrange:
' able portion of its length and iinc 't-wo adj a maximum for this character of device.
,1 urea 18 it c mutually eccentric convolutions,
' convolutlons that a're'uniformlg the s ring makes contact with each of these L members along1 three lines, which are sixb stantiall one undred and twenty degrees apart. 'le this exact relation of parts 1snot essential, it affords a satisfactory distribution of pressures and is probably more dc:- sirable than any other arrangement.
The spring here shown and described win generally be made 'of tempered resilient metal,
such as steel, in order to provide the maximum efiiciency but my invention is not lim-- ited to any specific materialor toany speof convolutions of which no two adjacent .eon'volutions are concentric.
A-helical sprin comprisinga plurality urvature' of which constitutes a helix.
3'. A helical spring comprising a plurality of convolutions all adjacent convolutions of which are displacedlaterallyrwith respect to each other. i l
4. A helical spring having a 5. As ring-cylinder comprising aseries of' spacedapart and at least a portidll 'of'whic eccentric.
6. A helical spring theadjacent turns of which are relatively displaced, in combination with an inclosing and an inclosed cylinder with which the spring makes contact along three lines substantially one hundred and twenty degrees a art,
7. Ahelical sprin aving'its adjacent convolutions laterally isplaced and having interior and exterior bearing-points alon incs that are substantially one hundre and twenty degrees apart. i 1
