  • Patent number: 8037648
    Abstract: A polymeric interlocking tile for an adhesive-free assemblage with adjacent tiles having substantially similar, but inverted, edge interlocks thereon. The interlocks on each edge of a tile include a row of first and second sets of male-female types of alternating interlocks. The first interlock set includes a male lug projection having sidewalls forming one sidewall of a channel of U-shaped cross-section. The channel forms a female interlock cavity for the first set. The second interlock set is contiguous to the first set and includes a male projecting rib having two parallel sidewalls, one sidewall faces the edge and forms an opposite sidewall of the channel and an opposite, inwardly facing sidewall forms an enclosure for a second female cavity of the next set. At the opposite ends of each interlock row, the U-shaped channel sidewalls are wider to facilitate an initial interlock meshing between contiguous tiles of the assemblage.

  • Patent number: 6229094
    Abstract: An insulator having a torque-resistant or torque-prevailing crimped insulator end fitting; including a method of crimping the insulator end fitting so as to be resistant to torque tending to loosen mounting bolt connections of the insulator. A fiberglass core is located in the insulator and protrudes from the opposite ends of the insulator, and has end fittings seated thereon in close interference engagement, by mounting the insulator through intermediary of the end fittings being attached to power devices by threaded bolts extending from the devices being engaged in the tapped bolt holes. Radially inwardly directed crimping forces are applied to the cylindrical wall structure of the end fittings intermediate the locations of the bosses having the bolts tightened within the threaded bolt holes, and thereby produce a bolt-locking deformation of the bolt holes.
