摘要：Secure and rapid assembly of magnets or other articles in tubular or other-shaped housings is achieved with bow type compression retainers which are made from reformable spring metal, and are initially formed shorter and higher than their ultimate working dimensions to permit loose or easy manual or automatic assembly in their final working location, after which the retainers can be reformed in place to a reduced height and extended length so as to take up any clearance and to place an initial load on abutting faces of the article to be secured. Then the bow shaped retainer is finally reworked in a comparatively small portion of its length, and in a direction which tends to change the natural curvature and extend the intrinsic unloaded length of the restrained bow, thus off-setting "spring back" type load losses characteristic of normal spring forming, and assuring maximum spring retention forces irrespective of large assembly tolerances and high spring rates. Provisions for metal curling or bending near the ends of the retainer can further extend tolerance take-up capabilities; and several preferred means are shown for accomplishing the final curvature-reversal loading of the retainers.
