    Abstract: A quick acting cam lock vise for use with drill presses and the like comprises fixed and movable jaws mounted on an elongate mounting bar. A spring urged over center toggle linkage is connected with a movable jaw and is operable to cam the jaw into gripping relation with the work piece, and is also operable to releasably lock the movable jaw with respect to the mounting bar. The toggle linkage includes a lock actuating member operatively connected with a pair of concavo-convex locking elements which grip the mounting bar when the toggle linkage is in the locking position.

    Abstract: A self-propelled water vehicle has a structural assembly which includes an elongate, water-tight hull adapted to provide seating for one or more persons along the top thereof and means, such as propellor or jet unit, for propelling the vehicle along the surface of a body of water. A control housing disposed at the forward end of the hull contains drive means operationally connected to the propelling means, and also encloses a steering control mechanism connected to a pair of pontoons disposed at opposite lateral sides, respectively, of the forward end of the hull. The pontoons are pivotally connected to the vehicle by support means. The vehicle is preferably constructed for conversion to a snowmobile by replacement of the pontoons and the water-tight hull, respectively, with pairs of skiis and an elongate snowmobile hull having endless track propelling means attached to the bottom thereof for propelling the vehicle over snow. In fact, existing snowmobiles may also be readily converted to the vehicle of the invention by use of the disclosed structural assembly.

    Abstract translation: 自行式水车辆具有结构组件，其包括细长的防水船体，其适于沿着其顶部为一个或多个人提供座椅，以及诸如推进器或喷射单元的装置，用于沿车辆的表面 一身水。 设置在船体的前端的控制壳体包含可操作地连接到推进装置的驱动装置，并且还包围连接到分别设置在船体前端的相对侧边处的一对浮筒的转向控制机构。 浮筒通过支撑装置枢转地连接到车辆。 优选地，车辆通过更换浮筒和水密船体来构建用于转换成雪地车辆，成对的滑雪板和具有附接到其底部的环形轨道推进装置的细长的雪地车体，以将车辆推向雪地。 事实上，现有的雪地车也可以通过使用所公开的结构组件容易地转换成本发明的车辆。
