Abstract: This is a system of providing lateral support to the block of a Scotch Yoke mechanism. The Scotch Yoke mechanism is useful in operators or devices which translate linear motion to rotary motion. The Scotch Yoke has a hub with an upper U-shaped member having two arms and a lower U-shaped member also having two arms. The hub is connected to a rod so that rotation of the hub rotates the rod. A drive screw or rod is between the upper and lower U-shaped arms and is provided with a block which has upper and lower rollers for engaging the Scotch Yoke assembly which is mounted in a housing. This whole mechanism may be called an operator. A new and improved way is provided for transmitting applied force which is imposed on the block to the housing proper.

Abstract: A locking means for securing pipe segments in end-to-end relationship wherein at least one pipe segment is slidably disposed within a sleeve member, and having cooperative grooves provided in the pipe segment and the sleeve member to provide an annular chamber when the pipe segments are coupled. A plurality of circular disc members having a diameter substantially equal to the sum of the depth of the grooves are inserted in the annular chamber for locking said coupling in place and providing high load capabilities with ease of coupling and uncoupling.
