Sealant applicator

A sealant applicator assembly for mounting on an automatic fastener installation machine including a movable fastener gripping and installation mechanism, said assembly comprising:

• a body member having a bottom surface and at least one upper surface portion;
• a first passage means in said body member that extends substantially vertically between said bottom surface and said upper surface portion;
• a second passage means in said body member extending from said bottom surface to the exterior of said body member, said second passage means adapted to have a sealant supply connected thereto to deliver sealant to said second passage means;
• the openings of said first and second passage means in the bottom surface of said body member being spaced whereby a portion of the bottom surface is located between the openings therein;
• a base plate means mounted to the bottom surface of the body member, the area of the body member bottom surface confronted by said base plate means encompassing no less than the openings of the first and second passage means and the bottom surface portion therebetween;
• a valve means located within said first passage means which is actuable by the tip of the shank end of a fastener held by said fastener gripping and installation mechanism being forcibly inserted into said first passage means from the upper surface portion of the body member;
• and a third passage means in said assembly interconnecting said first and second passage means whereby sealant may flow from the sealant supply to the fastener shank located in the first passage means when the valve means has been opened thereby.
