THEODORE H. MILLER, 01* POUGHKEEPSIE,
NEW YORK, ASSIGNOR TO THE DE LAYAL SEPARATOR COMPANY, A CORPORATION OF NEVKLJEBSEY.
SPRING FOR SPRING-BEARINGS.
To all whom it may concern Be it known that I, THEODORE H. MILLER,
Poughkeepsie, county of Dutchess, and State of New York, have invented a new and useful Improvement in Springs .for Spring. Bearings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
My'invention relates to a novel spring for use in a spring bearing and especially adapted for centrifugal separators.
In my invention a metal sheet or shell is bent or curved into the form of a cylinder outer support. 'From this metal sheet are cut and bent a series of fingers, which fingers are bent outwardly or inwardly and circumferentially. Certain of the fingers are arranged out of circumferential alinement with certain other fingers and also out of vertical alinement with the adjacent circumferential alinement. Preferably the I fingers are arranged in a plurality of cirl cuinferential rows, the fingers of one circumferential row being arranged alternately with respect to the fingers of an :adjacent j circumferential row, whereby there are provided a plurality of circumferential lines of L tact equal to substantially a multiple of the I will now describe the embodiment of my invention shown in 'the accompanying draw l ings in which' Figure 1 is a plan view of my improvement. Fig. 2 is a side elevation of the same.
a is the metal piece, 6, c and d the fingers which are cut and bent outwardly from the metal piece at difierent points, to lie circumferentially. As will be seen, the spring con- 1 tacts of fingers b are in circumferential alincment with each other and so with the contacts of fingers c and with the contacts i -of fingers (Z, but each set of fingers a, b and is out of circumferential alinement-with the othem sets of fingers. Each finger Z) is arranged in a' different planefroni the ad- 5 jac-ent fingers c, and each finger c is arranged in a different vertical plane from the adjacent' fingers d. In the embodiment shown, the fingers of each set are arranged alternately with respect to the fingers of an adl Specification of Letters Patent. Application filed October 1,

jacent set. More specifically, two fingers b. and d are arranged in the same vertical plane, the next adjacent finger c of the in termedlate set is arranged in a different vertical plane, and soon around the circumference of the spring. Thus, while there are only five fingers in each set, the spring fingers contact along'ten Vertical lines. Thereby the spring contact points are widely distrlbuted over the bearing surface, the fifteen fingers contacting at fifteen points measuring circumferentially and at ten points measuring vertically. As shown,
these fingers are bent outwardly, in which case they contact with the outer support.
They may be bent inwardly with the same result'ant construction, the only difference being that the fingers will then contact with the inner support (bearing or bushing). To secure the maximum elastic effect from the springs the same are not, in the preferred construction, bentout in the form of an arc of alcircle but each finger is bent approximately tangentially from its connected end to a point relatively near its outer extremity whence it is curved inwardly toward the shell, whereby the bearing point of the finger is near but not at its actual extremity.
I do not intend to limit myself'to forming the fingers by cutting and bending the sheet itself, although this method of forming the fingers is preferable, my invention residing in the arrangement and form of the fingers and not in the way in which each finger is formed from the sheet.
Having now fully-described my invention, what I claim and desire to protect ,by Letters Patent isz 1. ,A spring for sprin bearings comprisinga metal sheet of cy indrical form having bent out circumfer'ntially extending fingerseach of which is connected withthe metal 'sheet at one end only, said fingers being arranged in a plurality of circumferentially extending rows, each finger of one row being arranged out of vertical alinement with the nearest fingers of an adjacent circumferential row. T
2. A spring for spring bearings comprising a metal sheet of cylindrical form hav ing circumferentially extending fingers cut from the metal of the sheet and all projecting outwardly from the plane of the sheet in the same circumferential direction toward their free ends,'said fingers being arranged in a plurality of circumferential rows, each said fingers being arranged in a plurality of finger being arranged substantially midway between the two adjacent fingers'of an ad jacent circumferential row.
3. Aspring for spring bearings comprising a metal sheet of cylindrical form having circumferentially extending spring fingei's each of which 1s connected at one end tn the metal sheet and projects toward its free end in a substantially tangential directien and isbent at a point relatively near its free extremity toward the body of the shell,
circumferential rows, the fingers of' each row being arranged out ofvertical alinement 15 With, and alternately to, the fingers of an adjacent circumferential row. In testimony of which invention, I have hereunto set my hand, at Poughkeepsie, on. this 26th day of Sept, 1910.
