摘要： A hole cutting apparatus for use with a conventional drill and chuck. The apparatus features a self feed pilot bit and quick change drill bits which store on the apparatus. Hollow drill bits are provided which fit over a pilot bit and are fastened to the apparatus with a quick release pin. The pilot bit centers on the hole to be cut and the drill bit is used to cut a circular perimeter slot until through the workpiece. The apparatus fits in the chuck of a standard drill. The apparatus requires a relatively low torque from the drill motor to drill a large size hole when compared to conventional drilling systems.
摘要翻译：一种用于常规钻头和卡盘的孔切割装置。该设备具有自动馈送导频位和快速更换钻头，存储在设备上。提供空心钻头，其安装在导向钻头上并且用快速释放销紧固到设备。导向钻头位于待切割的孔上，钻头用于切割圆形周边槽，直到穿过工件。该装置适用于标准钻头的卡盘。与常规钻井系统相比，该装置需要来自钻机电机的相对较低的扭矩来钻出大尺寸的孔。

摘要： A faucet having a clamping mechanism having a guide and clamping arms retained by a detent in contracted position when in disengaged position for placing the faucet on a support wall with the clamping mechanism extending through an opening in the support wall. On connecting the water supply to the faucet valves, the water under pressure operates a hydraulic motor to automatically move the clamping arms toward engaged position to release the detent so a spring will expand the clamping arms to expanded position to engage the clamping side of the support wall in engaged position.
摘要翻译：一种具有夹紧机构的水龙头，该夹紧机构具有引导件和夹持臂，当处于脱离位置时，由棘爪保持在收缩位置，用于将所述龙头放置在支撑壁上，夹紧机构延伸穿过支撑壁中的开口。在将供水连接到水龙头阀上时，受压的水操作液压马达以自动地将夹持臂移动到接合位置以释放制动器，使得弹簧将使夹紧臂膨胀到扩张位置以与支撑件的夹紧侧接合墙在啮合的位置。

摘要： Apparatus for cutting a smooth concentric hole in a metal workpiece. The apparatus fits in a standard industrial drill chuck and has a pilot drill and tap at one end which drills and taps a pilot hole seating a mandrel on the metal workpiece. When the mandrel is seated, a cam plate and spring arrangement automatically advances the cutting teeth and provides the proper pressure on the cuttering teeth to cut the hole. The cutting teeth have a special anti-breakthrough portion which provides controlled drilling of a smooth hole. A clutch is provided which controls the torque delivered to the apparatus and allows the cam plate to function properly. The device may be adapted easily to accommodate various hole sizes by changing its faceplate.

摘要： A snap-on, easily removable, fluid shut off valve (with pipe and interlocking member) that is useful as a low cost, primary turn off valve for domestic and commercial fluid fixtures and is quickly installed by manual snap-on between the inlet fluid supply and the supply pipe to conventional fixtures such as faucets or the like. The valve comprises a rigid housing having an inlet chamber and an outlet chamber, and a cross-over passage separating the first and second chambers that houses a moveable ball or poppet valve member that is held in the cross-over chamber by a spring retainer. A mechanical plunger or cam device (operable from the exterior of the housing) is disposed within the outlet chamber for contacting and pushing the ball or poppet valve member against the spring retainer, away from the valve seat, to open the valve. The first and second chamber openings receive spiral-shaped spring pipe end retaining members, each having an inside diameter smaller than the outside diameter of the inserted pipe mounted between level bushings. Each spiral-shaped retaining member has radial segments that deform in the direction of the pipe inserted that interlocks the pipe end in each chamber. Cooperating fluid seals prevent leakage.
摘要翻译：可用作家用和商业流体固定装置的低成本主要关闭阀的快速可拆卸的流体截止阀（带有管道和互锁构件），并且通过手动卡扣在入口流体之间快速安装供应和供应到常规固定装置如龙头等。阀包括具有入口室和出口室的刚性壳体，以及分隔第一和第二腔室的横穿通道，其容纳通过弹簧保持器保持在交叉室中的可移动球体或提升阀构件。机械柱塞或凸轮装置（可从壳体的外部操作）设置在出口室内，用于接触并推动球或提升阀构件抵靠弹簧保持器远离阀座以打开阀。第一和第二腔室开口接收螺旋形的弹簧管端部保持构件，每个具有小于安装在层间衬套之间的插入管的外径的内径。每个螺旋形保持构件具有沿插入的管的方向变形的径向段，其互锁每个室中的管端。合作流体密封件防止泄漏。
