A pipe coupling includes a coupling body 50 and swage ring 52 for urging over the coupling body 50 in order to secure pipes 108 together. The coupling body 50 includes a first main sealing tooth 50 and a second outboard sealing tooth 56. The swage ring 52 includes a kickdown device 101 which restores a loading force between the first main sealing tooth 50 and the pipe 108, which loading force may have been reduced due to sequential tooth engagement and pipe radial deformation.

A bodyguide and holddown system for use with dump bodies mounted on vehicles, such as dump trucks and dump trailers. The system has complementary first and second guide and holddown mechanisms or components. One of the components is connected or affixed to the chassis of the dump truck or trailer, with the other component connected to an I-beam support of the dump body. During movement of the dump body from an elevated to a lowered position, the components interact with each other to center the dump body on the chassis. After the dump body has been centered on the chassis, the components interact with each other to releaseably hold the dump body on the chassis and to oppose lateral movement of the dump body with respect to the chassis.

An apparatus that holds playing cards is herein disclosed, employing a mirror system therein a housing to allow only the holder of the cards to view them, while reducing the holding and movement of the cards. To use, a user would slide the cards face-down from below onto a level surface of the apparatus. Once in place, a set of mirrors would be used to allow only the player to see the value on face of the cards. This feature restricts other players to view the cards and also reduces the possibility of “body language” providing clues as to the value of the cards. Additionally, the apparatus allows players without the use of their hands or arms to play a game of cards as well. Also, cards would not be subject to damage from frequent bending and lifting.

A pipe fitting 20 adapted for joining pipe 28, 30 comprises a swage ring 22, 24, 52 with a locking mechanism area 42, 63 which can lockingly engage with either a coupling body 26 and/or a pipe 28, 30, 56 which has a locking mechanism 44, 64 in order to prevent relative motion between the swage ring 22, 24 and the coupling body 26 and/or the swage ring 52 and the pipe 56. Such an arrangement prevents the swage ring 22, 24 from backing off of the fitting 20 should the fitting 20 be subject to flexing due to bending forces.

A pipe coupling including a coupling body and swage rings for urging over the coupling body in order to secure the pipes together. The coupling body includes a main sealing tooth with an outboard isolation tooth and an inboard tooth located on opposite sides of the main sealing tooth. First and second grooves are defined between the main sealing tooth and the outboard isolation tooth and the inboard tooth, which grooves are of sufficient length and depth so that pipe secured by the coupling is not substantially deformed adjacent the first and second grooves in order to enhance the ability of the main sealing tooth to bite into the pipe in order to provide a hermetic seal and also to increase the resistance of the coupling to tensile loads. The outboard isolation tooth and inboard tooth protect the seal created by the main sealing tooth from external forces caused by bending. The main sealing tooth can include a twin tooth having a parent tooth and one or more sealing teeth extending therefrom.
