Abstract: A device for the testing of anchorages in, protrusions from, or attachments to surfaces (collectively, "anchorage hardware") is connected to the anchorage hardware under test and rests against the surface. A slidable coupler is positioned within an enclosure under a mounting plate and to which the hardware to be tested is attached. A spring within part of the device is used to apply a calibrated loading force between the anchorage and the surface. A cam determines the spacing between the enclosure and a spring assembly housing, causing motion of the coupler and transfer of the force of the spring to the hardware under test. The device may include an indicator to measure the force applied.

Abstract: A device for splicing together aerial drop wires and comprising: (a) a housing shell having a throughpassage (b) a partition dividing such passage into two channels with outer ramp walls causing the channels to have respective wide openings at opposite ends of the passage and narrow openings at the other ends of the channels, (c) insulating piercing terminals projecting from the partition into these channels and adapted to electrically splice together conductor inserted through the narrow openings into the channels, and (d) wedges drivable through the wide openings to press the drop wires against the terminals and then squeeze the drop wires between the partition and the wedges, is characterized by the following improvements. The wedges are smooth surfaced on their sides which contact the drop wires. Different size wedges are provided to accommodate different size drop wires in the channels. Affixed to the partition are ribs projecting into the channels at their wide ends.

Abstract: A splicing device is disclosed wherein the conductor and steel support cable portions of an aerial drop wire are each spliced utilizing a single device which is electrically insulated and weather-resistant and has a central member and end caps separable therefrom. The ends of the steel support cable are joined together by a wire linking device integrally molded in the central body and the conductors are spliced together by button-blade terminals driven into conductor-receiving cavities within the same body becoming locked in place. The risk of environmental damage is eliminated by the end caps which protect the stripped portions of the conductors, as well as by the unitary body construction of the central member which provides a sealed environment for the splices themselves.

Abstract: A guy hook used to attach a guy cable to a transmission line pole includes an upper body portion (25), a central body portion (26), and a lower heel portion (27). The upper portion has a neck (29) and ears (28) for engaging the guy cable. The central body portion has a rearward pole-engaging surface (37), an opposite frontward side and a passageway (40) therebetween through which a through-bolt is horizontally disposed to install the hook on the pole. The frontward side includes a recess (38) surrounding the aperture (39) to the passageway for countersinking the head of a through-bolt below the frontward side to a depth substantially in line with the vertical line of action (41-42) of the hook. The moment caused by the downward and outward force exerted on the hook by the guy cable is thus minimized and therefore also the tendency of the hook to overturn and bend the through-bolt.

Abstract: Apparatus for effecting a drop wire splice comprises an enclosure having a pair of channels with each channel extending from an entrance end to an exit end. A partition is located between the channels and a ramped surface is located on a wall of each channel opposite the partition with the ramped surface widening each channel as it extends from its entrance to exit end. Embedded in the partition are a pair of electrically conductive terminals each of which comprises tangs extending into each channel at an angle inclined toward the exit end. The apparatus further comprises a pair of wedges for insertion into the exit end of each channel.
