    摘要： This invention pertains to an improvement in box joint tools and particularly for reducing play resulting from wear of the members forming the box joint. The box joint is formed in the usual manner. This improved joint is used when or where wear develops or may be utilized with new tools at the time of assembly. A first portion outer member of the box joint is machined to provide a counterbore and an enlarged bore in this member portion. A counterbore is also formed in the second outer member portion and extends to about one thirty second of an inch from a central jaw tongue portion. This counterbore provides a flexure portion with a smaller bore axially coincidental with the axis of the central portion. A pivot pin bushing has a threaded bore and is sized to be a press fit in the formed counterbore and enlarged bore of the first outer member. This bushing is mounted in the first outer member and the shank portion extends into the tongue portion of the central jaw. This extending portion of the bushing provides the pivot for this jaw portion. A securing screw is mounted in the second outer member and is tightened in the threaded portion of the bushing to bring the member portions of the box joint into a sliding relationship absent unwanted play. The box joint is shown in certain embodiments with a thin washer under the head of the cap screw. This washer is of metal or of plastic such as Teflon.

    摘要： This invention pertains to a box joint for use with plier-type tools and the like. These tools are pivotally retained with two members having handles and jaws. The box joint provided has a first member with a midportion of conventional construction and with an aperture through which the shank of a shoulder screw is passed. A second member has its outer wall portions formed with one wall integral with and extending from the handle to the jaw portion and the other outer wall having a transverse opening therethrough with each end of this opening made as a shouldered or stepped end. The opening and the stepped end configuration has the narrower opening at the inner portion and through this narrower opening the midportion of the first member passes when and while normal to its closed or in-use condition. The inturned shoulders adjacent the stepped opening of the second member are adapted to engage and retain the midportion of the first member when the first and second members are moved to the closed and operating condition. A retaining plate is sized to be snugly seated in the stepped opening and has a through aperture in which the shank of the retaining cap screw is passed. A threaded end of the cap screw is mounted in a threaded aperture in the integral outer wall of the second member. The jaws of the first and second members can and are hardened or provided with inserts and all surfaces of the box joint plate and jaws are precisely finished without distortion as would occur from the conventional use of heat or applied pressure.

    摘要翻译： 本发明涉及一种用于钳型工具等的盒式接头。 这些工具枢转地保持有两个具有手柄和夹爪的构件。 提供的箱体接头具有第一构件，其具有常规结构的中部部分，并且具有孔，肩螺钉的柄穿过该孔。 第二构件具有其外壁部分，其形成有与手柄一体地并延伸到颚部的一个壁，另一个外壁具有穿过的横向开口，该开口的每个端部形成为肩部或阶梯端。 开口和阶梯端构造在内部具有较窄的开口，并且通过该较窄的开口，第一构件的中间部分在其闭合或使用状态正常时通过。 当第一和第二构件移动到关闭和操作状态时，邻近第二构件的阶梯式开口的内翻肩部适于接合和保持第一构件的中间部分。 保持板的尺寸设置成紧密地安置在阶梯式开口中，并且具有通孔，保持帽螺钉的柄通过该通孔。 帽螺钉的螺纹端安装在第二构件的整体外壁中的螺纹孔中。 第一和第二构件的夹爪可以并且被硬化或设置有插入件，并且盒接头板和夹爪的所有表面都精确地完成，而不会像常规使用的加热或施加的压力那样发生变形。

    摘要： A PAIR OF PLIERS WHICH IS FORMED WITH A PAIR OF COMPLEMENTARY MEMBERS. EACH OF THE MEMBERS HAS A JAW PORTION, A HANDLE PORTION AND AN INTERMEDIATE ARCUATE PORTION WHICH IS INTEGRAL THEREWITH. AN ARCUATE SPRING IS PROVIDED BETWEEN THE ARCUATE PORTIONS OF THE MEMBER AND IS EMBRACED THEREBY. THE SPRING AND COMPLEMENTARY MEMBERS ARE CONFINED SO THAT MOVEMENT OF THE SPRING AND THE COMPLEMENTARY MEMBERS IS IN THE SAME PLANE WITH RESPECT TO EACH OTHER. THE SPRING URGES THE JAWS TOGETHER SO THAT THE JAWS ARE SPACED ONLY BY URGING THE HANDLES TOGETHER.
