    • An adjustable stop assembly for use with a drill press including a ratchet bar adapted to be vertically positioned between spaced ears on the housing of the press and adapted to pass through an annular quill stop carried by the quill of the press so that the quill stop moves up and down the ratchet bar in response to vertical movement of the quill. A slide assembly is positioned on the ratchet bar and includes a slide, a ratchet dog, a stop nut, and a lock nut. The slide includes a lower annular base portion, an upper externally threaded barrel portion, and a central bore slidably passing the ratchet bar. The ratchet dog comprises a spring biased plunger mounted in the slide base portion and having an inner tip for ratcheting engagement with the ratchet bar. The stop nut and the lock nut are threaded onto the externally threaded barrel portion of the slide. To adjust the stop setting of the press, and thereby the extent to which the associated bit or other tool will be moved into the workpiece, the plunger of the ratchet dog is pulled out to release the slide, the slide is moved in a gross manner along the ratchet bar to achieve an approximation of the desired final setting, the stop nut is moved threadably on the threaded barrel portion of the slide to achieve the final precise setting, and the lock nut is rotated to lock the stop nut.
    • 一种用于钻床的可调式止动组件,其包括棘轮杆,所述棘轮杆适于竖直地定位在压力机壳体上的隔开的耳朵之间,并且适于穿过由压力机的羽毛管承载的环形羽绒被,使得羽绒停止移动 响应于羽毛笔的垂直运动,上下棘轮杆。 滑动组件定位在棘轮杆上,并包括滑块,棘轮,止动螺母和锁紧螺母。 滑动件包括下环形底座部分,上部外螺纹筒部分和可滑动地通过棘轮杆的中心孔。 棘轮包括安装在滑动基座部分中并具有用于与棘轮杆棘轮接合的内部尖端的弹簧偏置柱塞。 止动螺母和锁紧螺母拧入滑块的外螺纹筒部分。 为了调整压机的停止设定,从而使相关钻头或其他工具移动到工件中的程度,棘轮的柱塞被拉出以释放滑块,滑块以粗略方式移动 沿着棘轮杆实现所需最终设定的近似,止动螺母螺纹移动到滑动件的螺纹筒部上以实现最终精确设定,并且锁定螺母旋转以锁定止动螺母。

    • Abstract disclosed herein is a combination depth gauge and level for a drill characterized in that a plunger mechanism is attached to the drill by means of a band type clamp. Overlying the plunger, there is provided a ruler capable of sliding within the trackway to extend out beyond the drill and bit so that the depth of a hole to be drilled can be accurately gauged. The plunger mechanism includes a casing having a spring disposed therein and the plunger is biased against the spring and has a terminal portion preferably in the shape of a cross. In use and operation, the plunger is depressed against the surface upon which the drilling is to be done, and therefor the correct angle of the drilled hole can be assured. Once the plunger has been depressed up to the length of the ruler as it has been extended beyond the drill, the depth of the hole thus drilled can be accurately determined and controlled.
    • 本文公开的摘要是用于钻头的组合深度计和液位,其特征在于,柱塞机构通过带式夹具附接到钻头。 在柱塞上方,设置有能够在轨道内滑动以便超出钻头和钻头的尺子,使得能够精确地测量待钻孔的深度。 柱塞机构包括具有设置在其中的弹簧的壳体,并且柱塞偏压弹簧并且具有优选地为十字形的端子部分。 在使用和操作中,柱塞被压在要进行钻孔的表面上,从而可以确保钻孔的正确角度。 一旦柱塞已经被延伸到尺子的长度,直到其延伸超过钻头,则可精确地确定和控制钻孔的深度。

    • A dust-intercepting member is so mounted on a hand-held power tool as to contact a structure being acted upon around the tool element of the power tool, by a mounting arrangement which includes two hollow elongated mounting members one of which is received within the other for telescoping relative thereto while being retained against rotation with respect to the other mounting member about the common axis of the mounting members, and a helical compression spring the ends of which are respectively received in the interiors of the mounting members and urge the latter in opposite directions. The other mounting member is attached to an auxiliary hand grip which, in turn, is mounted on a cylindrical extension of the housing by a quick-release clamping arrangement. A setting ring on the inner one of the mounting members determines the depth of penetration of the tool element into the structure. A depth-determining profiled rod is displaceably and arrestably mounted on the auxiliary hand grip. The outer one of the mounting members is connected to the profiled rod when the intercepting arrangement is mounted on the auxiliary hand grip.
