摘要： A tool for actuating hammer unions. The tool provides for an arcuate tool head having an aperture which receives the lug or tab of the union. Extending outwardly from the arcuate tool head is a lever member which is designed to receive a handle [selected by the user for appropriate length and torque] for the user to hold and apply the necessary amount of torque to tighten or loosen the hammer union. By receiving the tab in the arcuate head, the user is precluded from damaging the tabs or lugs since no impact is received by the latter and a maximum amount of work can be done safely by the user. Structural features are also provided to prevent improper use of the tool.
摘要翻译：用于致动锤子工会的工具。该工具提供了一种弓形工具头，该工具头具有接收该联接件的凸耳或凸片的孔。从弓形工具头向外延伸的是杠杆构件，其被设计成接收由用户选择的适当长度和扭矩的手柄，用于使用者保持并施加必要量的扭矩以收紧或松开锤头联接件。通过接收弓形头部中的卡舌，用户不会损坏卡舌或凸耳，因为后者没有接收到冲击，并且使用者可以安全地完成最大量的工作。还提供了结构特征以防止工具的不当使用。

摘要： A tool for actuating hammer unions. The tool provides for an arcuate tool head having a disposed variant and an aperture which receives the lug or tab of the union. Extending outwardly the arcuate tool head is a lever member which may be used to strike a surface to loosen or tighten the union or alternatively, receive a handle for increasing the amount of torque that can be applied to the union by a user. By receiving the tab in the arcuate head, the user is precluded from damaging the tabs or lugs since no impact is received by the latter and a maximum amount of work can be done safely by the user.
摘要翻译：用于致动锤子工会的工具。该工具提供了具有设置变体的弧形工具头和容纳接合件的凸耳或凸片的孔。向外延伸的弧形工具头是杠杆构件，其可用于撞击表面以松开或拧紧联接件，或者替代地，接收手柄以增加可由用户施加到联接件的扭矩的量。通过接收弓形头部中的卡舌，用户不会损坏卡舌或凸耳，因为后者没有接收到冲击，并且使用者可以安全地完成最大量的工作。
