Its condition depends upon care, wear and ease of


adjustment to offset the effects of wear.


During the past few years, our experts- co- workers


and successors of those who led the Spindle improvements


of the 70' s and 80' s- have produced devices that have


added years to the life efficiency of our spindles by


reducing the wear and by increasing the ease and range


of adjustment to offset the effects of wear.


These improvements have come into increased use


without very much publicity during the past half dozen


years they have been on the market. They have long


passed the experimental stage. They have been tried and


proved.


WIRE- PACKED BOLSTER


Our Wire- Packed Bolster, the wire spring of which is


specially wound with cushion projections, is proving a


great improvement on the old type of bolster with wool


packing. Time and use caused the wool packing to harden


or flatten out, allowing the spindle to vibrate.. This cannot


happen with the wire- packed bolster. Spindle vibration


comes only with the actual wearing of the bolster, and this


is delayed and retarded by the better oil distribution


effected by the wire packing.


The cost of repacking is eliminated. The wire packing


lasts until the bolster wears out.


Our Adjustable Step, designed to take up the wear


upon the Spindle and Bolster by dropping the Spindle and


so restoring the proper relation between the taper of these


two parts and preventing vibration. was a feature of our


original 49D spindle, where both Bolster and. Step were


locked in the Base.


With our D2 spindle, a spring lock for the Step was


introduced so that Bolster and Step might be taken out,


adjusted and put back without danger of changing the


adjustment. Only the Step was locked in the Base.


With the Wire- Packed Bolster, used in our Spindles


of the D6 series, the locking key has been changed from


the bottom of the Base to the top, where it locks the


Bolster instead of the Step. This facilitates both removal


and replacement and prevents change in adjustment except


when purposely made.


Together the Wire- P, acked Bolster and Adjustable Step


have lengthened the productive life of the Spindle so that


it is found doing satisfactory work after years of use.


Under many conditions the extreme length of this life is


yet to be determined.


The D6 Spindle, Rabbeth type, is similar in length and


weight to the D2 spindle with the wool packing.


Where new Spindles complete with Bases are being


purchased we generally recommend the D7 instead of the


49D or D2, or of the D6 which replaces either. It has a


longer Base and longer bearing with a better taper. It


requires a little more power, but is steadier. The D7 is


similar in length and weight to the old DS..


For heavy package. in place of the old D4, the new


spindle is the D8.


IMPROVED CENTRIFUGAL CLUTCH


Because of the increased use of the Feeler to meet the


more exacting demands of the cloth market. the centrifugal


clutch with its assurance of uniformity in the placing of


the yarn on the bobbin is of growing importance to both


the Spinner and Weaver.


The Nutting clutch is a very important improvement


on this Spindle. The segments are now made with a lug


at the bottom and are held in place by a collar forced into


the whorl so that the tension of the spring behind the


segments is taken by the lugs and collar rather than by the


collar on the blade. This has greatly lengthened the life of


the centrifugal clutch spindle and done away with the need


of clutch repairs.
