ALEAF spring which is allowed to become rusty loses its value as a shock-absorbing medium and, in time, may actually 'become a shock-transmitter. One of the reasons for neglect of spring lubrication is the difficulty experienced' in separating the leaves so as to be able to insert grease or oil. To overcome this obstacle Herbert Terry and Sons, Ltd., of Redditeh, markets a leaf-spring greaser of the type shown in the accompanying illustration. The fixed wedgeshaped blade is passedinside the spring whilst the movable blade is outside it. Rotation of the screwed bar forces the spring leaves apart and the grease-gun is then applied to
the nipple fitted to the end of the bar ; lubricant exude, through an aperture in the movable blade.
In operation, the clip around the spring leaves has to be removed before applying the greaser. The price a the device is 8s. 6d., and it is supplied with a niPple suitable for use with either an Enots or Tecalemit gun.
