摘要： A taper tool for applying tape to a wall surface is provided. The taper tool may simultaneously advance tape and apply mastic to the advancing tape. The taper tool may include a jam clearing assembly for clearing tape jams occurring along the tape path. The taper tool may include a body for holding mastic and a taper head coupled to an end of the body. The taper head includes a housing defining an opening and a mastic ejection nozzle, both of which are in fluid communication with the body. The opening facilitates introduction of mastic into the body and the nozzle facilitates ejection of the mastic from the body onto the tape. The taper head also includes a valve positioned within the opening to control introduction of mastic into the body, and a cover plate removeably connected to the housing to cover both the opening and the nozzle.
摘要翻译：提供了用于将胶带施加到壁表面的锥形工具。锥形工具可以同时推进胶带并将胶泥涂抹到前进的胶带上。锥形工具可以包括用于清除沿着磁带路径发生的磁带卡纸的卡纸清除组件。锥形工具可以包括用于保持乳胶的主体和联接到主体的端部的锥形头。锥形头部包括限定开口的壳体和胶体喷射喷嘴，两者都与主体流体连通。该开口有助于将胶乳引入体内，并且喷嘴便于将胶乳从身体排出到胶带上。锥形头还包括位于开口内的阀门，用于控制乳胶进入体内，以及可拆卸地连接到壳体以覆盖开口和喷嘴两者的盖板。

摘要： An extendable handle for a drywall tool having a pair of telescoping tubes that are reversibly locked in place relative to each other by a locking assembly comprising a lever, a pin and a yoke that are mounted on a base positioned on a first tube. The pin is actuated by the lever and engages an opening on the second tube to lock the tubes in place. The pin and lever are spaced apart circumferentially on the handle and are connected by the yoke. The yoke is received in a slot in the base and does not extend beyond the surface of base during operation of the lever.
摘要翻译：一种用于干墙工具的可延伸手柄，其具有一对伸缩管，所述一对伸缩管通过包括杆，销和轭的锁定组件相对于彼此可逆地锁定就位，所述锁定组件安装在位于第一管上的基座上。销由杠杆驱动并与第二管上的开口接合，以将管锁定在适当的位置。销和杠杆在手柄上周向间隔开并且通过轭连接。磁轭被容纳在基座中的槽中，并且在杠杆的操作期间不延伸超过基座的表面。

摘要： The invention provides a powered pumping system for filling various batch application tools with a viscous material. The system includes a motor mounted on a wheeled frame. The motor drives a slider-crank mechanism attached to a displacement pump. Affixed to the pump outlet is a relief valve having a plurality of predetermined relief pressure settings. The relief valve serves as a conduit between the pump and any one of various batch application tools while the tool is being filled with the viscous material. To initiate pumping, operators connect a filler valve of the tool to a relief valve outlet and actuate a switch. The relief valve of the present invention automatically selects a relief pressure appropriate for the particular tool based on certain physical characteristics of the particular tool. The selection of the appropriate relief pressure requires no operator intervention. Releasing the switch stops the pumping action.
