摘要： A jack is mounted on a trailer tongue by a swivel connection to pivot between a vertically disposed active position and a horizontally disposed stowed position. The swivel connection includes a spacer sandwiched between a bracket on the tongue of the trailer and a bracket on the housing of the jack and rotatably received in a hole in the tongue bracket. The spacer serves to hold the two brackets out of contact with one another. A bolt extends through the housing bracket and the spacer with a non-rotatable fit and causes the housing bracket and the spacer to turn in unison relative to the tongue bracket. A nut and washer on the inner end of the bolt clamp the brackets together while allowing the housing bracket to pivot relative to the tongue bracket. The tongue bracket may either be clamped to the tongue by bolts or may be bolted to still another bracket which is welded to the tongue.
摘要翻译：千斤顶通过旋转连接件安装在拖车舌上，以在垂直设置的主动位置和水平放置的收起位置之间枢转。旋转连接件包括夹在拖车舌部之间的支架和插座壳体上的支架之间的间隔件，并可旋转地容纳在舌支架中的孔中。间隔件用于保持两个支架彼此不接触。螺栓通过不可旋转的配合件延伸穿过壳体支架和间隔件，并使壳体支架和间隔件相对于舌支架一致地转动。螺栓内端的螺母和垫圈将支架夹在一起，同时允许外壳支架相对于舌支架枢转。舌支架可以通过螺栓夹紧到舌头，或者可以被螺栓连接到另一个被焊接到舌头的托架上。

摘要： The ball clamp of a trailer coupler is supported by the coupler body to move back and forth between a clamped position holding a ballhead in the socket of the coupler and a released position permitting the socket to be pulled upwardly off of the ballhead. To hold the ball clamp in a correct angular orientation relative to the ballhead, a cylindrical tube is wedged between the upper side of the ball clamp and an inclined upper wall of the coupler body and is secured rigidly in place by staking metal of the side walls of the body into the end portions of the tube. The ball clamp is held in its clamped position by a pivoted yoke having transversely spaced arms which straddle the coupler body and having transversely spaced ears which straddle a latch. Each arm and each ear are integral with one another along a substantial length of the arm so as to improve the structural strength of the yoke.
摘要翻译：拖车联轴器的球形夹具由联接器主体支撑，以在夹持在联接器的插座中的球头的夹紧位置和允许插座从球头向上拉之间的释放位置之间来回移动。为了将球夹夹持在相对于球头的正确角度定位中，圆柱形管楔入球夹的上侧和联接器主体的倾斜上壁之间，并且通过将侧壁的金属的身体进入管的端部。球形夹具通过具有横向隔开的臂的枢转轭保持在其夹紧位置，所述臂跨过联接器主体并具有跨过闩锁的横向隔开的耳朵。每个臂和每个耳朵沿着臂的相当长度彼此成一体，以提高轭的结构强度。
