Abstract: A terminal crimping apparatus for performing a crimping operation to crimp a wire barrel end of an electrical terminal on a stripped bare wire end of an electrical conductor, includes a reciprocal ram having a crimping tool cooperable with a crimping anvil and movable between a die open or ready position and a crimping position. The crimping apparatus also includes a device for monitoring the crimped height of the terminal on the conductor during each crimping operation. The monitoring device can be adjusted to accommodate different terminal and conductor configurations. Once calibrated, the monitoring device can be operated in an automatic mode and can be set to automatically stop the terminal crimping apparatus in the event that the crimped height of a terminal and conductor is greater than a selectable and setable high limit or is less than a selectable and setable low limit. The monitoring device operates on the principle that there is a relationship between crimping pressure and desired crimped height.

Abstract: A boat hoist comprising a column, a tubular hoist slidable vertically, on said column, a boat cradle on said hoist, shore reinforcement means to anchor an upper part of said column to the shore, and a power unit connecting said column and hoist.

Abstract: The invention comprises an assembled electrical lamp socket construction having novel integral sealing means for the tower end derived from axial installation of a split plug wedging compressively within an outer socket shell and against insulation of wiring passing therethrough to retain electrical circuit contact assemblies in the tower. The plug is inserted with interengaging tapered surfaces in the tower end of the socket shell producing snap-in fit for the circumferential compressive engagement of the plug with the shell and a second interference compressive fit for the mating surfaces of the split plug halves. Apertures for insulated electric wires are formed in the mating surfaces with circumferential protrusions that encapsulate and compressively penetrate the wire insulation to form a seal thereabout.

Abstract: Structure equivalent to conventional printed circuits is made by forming round wires, usually copper, into the shapes the conductor strips are to occupy, fixing the wires to a surface of a thin plastic sheet, and then pressing the assembly between flat opposed die surfaces to form the wires into thin flat flexible strips.

Abstract: Feed mechanism for a continuous strip having a series of uniformly spaced holes in which an endless conveyor having a multiplicity of laterally projecting pins is adapted to engage one side of the strip with a plurality of pins extending simultaneously into a corresponding plurality of holes, together with means for driving the conveyor so as to advance the continuous strip.

Abstract: Stop feed mechanism for feeding continuous stock having uniformly spaced abutments thereon in which a resiliently biased dog is moved rearwardly over an abutment and then is moved forwardly in a feeding stroke in which it engages the abutment. Means are provided for sensing when the supply of continuous stock is nearly exhausted and for interrupting further feed by blocking engagement of the dog with an abutment during the feeding stroke.
