  • Patent number: 4359965
    Abstract: A sealant applicator assembly (10) for mounting to an automatic drilling and fastener installation machine to apply sealant to the tip or shank surface of a fastener (14) before "wet" installation of the fastener into a hole. The assembly (10) includes a valve member (21) that is opened or actuated by physical movement of the fastener (14) therewith whereby sealant flows into contact with the fastener shank. Upon removal of the fastener (14) from contact with the valve members (21), valve closure takes place due to sealant pressure and sealant flow is stopped. By sequencing the sealant application onto the fastener concurrently with drilling or other hole preparation by the automatic machine, cycle time for "wet" fastener installation is minimized.

  • Patent number: 4219936
    Abstract: A gage for measuring the angularity of the centerline of straight and/or tapered holes with respect to a flat surface. A tapered pin is inserted into the tapered hole and the gage is placed over the pin and pushed against the surface of the material with the hole in it. A dial indicator provides a direct reading of the angle that the centerline of the hole varies from being perpendicular to the surface. For straight holes, an expanding collet is first inserted into the hole and then the tapered pin is inserted into the collet causing the collet to expand against the sides of the hole and provide an accurate reading on the indicator.
