LOCK WASHERS
There arc probably a thousand ,or more bolts and nuts on the automobile. If these bolts or these nuts become loose they will not do that for which they have been furnished. For this reason a nut or bolt must never be put in without some thought being given to prevent its becoming loose. It must be locked in some way. Each week, for tho last 30 or 40 years, many patents have been issued on nut locking devices, showing that this is one problem, which has not yet been solved to entire satisfaction. Lock-washers are very successful on the whole, but are not absolutely reliable. If tho bolt is long and subjected to much vibration, or if the load on it is intermittent, as a blow, the bolt may stretch, and so the pressure on tho washer will be decreased and the nut may turn. It is necessary, therefore, to periodically test the nuts. This type of washer should not be used in places where it cannot be got at and tested.
