  • Pipe saddle
    Patent number: 6767033
    Abstract: A pipe saddle having an elongated band with a radially outward extending hub on one end and a set of teeth extending along a latching member. The hub includes a finger engagement region and an internal tooth for engagement with one of the teeth in a set of teeth on the latching member. A finger engagement region on the latching member allows a user to use one hand to extend the latching member into the hub and to push the latching member into locking engagement in the hub by compressively squeezing on the two finger regions. In order to prevent withdrawal of the latching member from the hub a stop in the hub maintains the teeth in engagement with each other thereby maintaining the band in pressure engagement with a circumferential region of a pipe. Use of multiple teeth permits the pipe saddle to be used on different diameter pipes.

  • Tap and saddle for forming a hinged coupon
    Patent number: 6510865
    Abstract: A hollow tap having an axially outward extending cutting tooth so that when the cutting tooth is brought into rotational pressure engagement with a resilient tubing the cutting tooth cuts a hole partially through the resilient tubing leaving a coupon hingedly but securely attached to the resilient tubing to maintain the coupon in an out-of-the-way condition within the resilient tubing. Continued rotation of the tap within a saddle brings a sealing surface on the cutting tube into fluid tight seal with the resilient tubing to provide a branch outlet to the resilient tubing though the tap.
