摘要： A rough cutter rotary mining tool formed of a support lug having an elongated, open ended, cylindrical bore and a cutter bit having a cylindrical shank portion extending through and loosely fitted within the bore, with the cutter head portion extending a distance beyond the forward end of the bore. An integral shoulder portion is arranged between the head and shank portions for engaging the lug at the forward end of the bore and a removable retaining clip is mounted upon the free end of the shank portion for engaging the rear end of the lug at the bore. The shank portion is loosely movable endwise a short distance relative to the bore. Also, the diameter of the shank portion is considerably smaller than the bore portion to form a space therebetween and so that the shank may easily rotate within and move transversely of the bore. Thus, small sand-like particles may pass through the bore around the shank during use of the tool.
摘要翻译：一种由具有细长的，开口的圆柱形孔的支撑凸耳形成的粗铣刀旋转采矿工具和具有延伸穿过并松散地配合在孔内的圆柱形柄部分的刀头，刀头部分延伸超过前端的孔。在头部和柄部之间布置有整体的肩部，用于在孔的前端处接合凸耳，并且可拆卸的保持夹安装在柄部的自由端上，用于接合在孔处的凸耳的后端。柄部分可相对于孔径向可移动地短距离移动。此外，柄部分的直径明显小于孔部分，以在它们之间形成空间，并且使得柄部可容易地在孔内旋转并横向移动。因此，在使用工具时，小的沙状颗粒可以穿过柄周围的孔。

摘要： This invention resides in providing a resilient, ring-like member between a work tool and a work tool holder so as, in many cases, to permit relative motion, axial and/or rotative, between them. The work tool and work tool holder are intended for use primarily in connection with mining, excavating and earth working machines and the like. The work tool may comprise elongated elements having a shank portion with a working tip at one end and a gauge-determining abutment surface at at least the other end. The work tool holders may comprise bodies having a shank receiving perforation and means in association with the bottom of the perforation having an abutment adapted to cooperate with the abutment on the work tool. The ring-like member may be positioned in a groove on the work tool with a portion thereof adapted to abut some part of the work tool holder or it may be located in a groove in the work tool holder with a portion thereof adapted to engage a shallow depression or the like in the work tool. The resiliency and shape of the ring-like member permits the work tool to be forced into the work tool holder whereafter it will often be movable with respect thereto but captively held. The ring-like member may be formed of metal or plastic and may have a variety of shapes, for the most part, however, having a generally cylindrical, at least in part, configuration. The working portion of this resilient, generally cylindrical, ring-like retainer is capable of axial elongation whereby to present a knock-in, pryout relationship between the work tool and work tool holder.
摘要翻译：本发明在于在工作工具和作业工具夹具之间提供弹性的环状构件，以便在许多情况下允许它们之间的相对运动，轴向和/或旋转。工作工具和工作工具架主要用于采矿，挖掘和土方工程机械等。工作工具可以包括细长元件，其具有在一端具有工作末端的柄部分和至少另一端处的计量确定邻接表面。工作工具保持器可以包括具有接收穿孔的柄的主体，并且与穿孔的底部相关联的装置具有适于与工件上的邻接部配合的邻接部。环状构件可以定位在工作工具上的凹槽中，其一部分适于邻接作业工具保持器的一些部分，或者可以位于工作工具保持器的凹槽中，其一部分适于接合工作工具中的浅凹陷等。环形构件的弹性和形状允许工作工具被迫进入工作工具保持器，然后通常可以相对于其移动，但被紧紧地保持。环形构件可以由金属或塑料形成，并且可以具有各种形状，但是大部分具有大致圆柱形的至少部分构型。这种弹性的，大致圆柱形的环形保持器的工作部分能够轴向伸长，从而在作业工具和作业工具架之间呈现出敲击的撬动关系。

摘要： Resilient retaining means for securing work tools either rotatable or non-rotatable, in appropriate work tools holders or mounting means. The work tools and holders are intended primarily for use on mining, excavating and earth working machines and the like. The work tools comprise elongated elements having a shank portion with a working tip at one end and a gauge-determining abutment surface at at least the other end. The holders or mounting means comprise bodies having a shank receiving perforation and means in association with the bottom of the perforation having an abutment surface adapted to cooperate with the abutment surface on the work tool. Either the work tool or the holder, and in a few cases, both, is provided with a recess to receive a resilient retaining means, usually, in the present invention, a special form of spring clip, to frictionally retain the work tool in the holder against longitudinal movement. In some cases the spring clip will be captive in the holder and will frictionally engage the work tool shank portion in such manner that the work tool will be non-rotatable in the shank receiving portion of the holder. In other cases the spring clip will also be captive in the holder and will also frictionally engage the shank but both the shank and retainer will rotate together with respect to the perforation. And in still other cases the spring clip will be captive on the shank, in a particular manner, and will frictionally engage the lug, the work tool usually being rotatable within the clip and perforation. Some of the clips may be arranged to either permit or prevent rotation of the work tool in the perforation. Various configurations and characteristics will be given these clips, such as special shapes, surfaces and twists.

摘要： A retainer clip for tool bits comprises an annular strip having circumferentially spaced ends defining a gap therebetween. A pair of proximate projections and at least one remote projection project outwardly from the strip. The proximate projections are located on opposite sides of the gap. The proximate projections include positively oriented front surfaces, and the remote projection includes a non-positively oriented front surface disposed longitudinally rearwardly relative to forwardmost portions of the front surfaces of the proximate projections. Upon forward displacement of the clip within the hole of a holder, contact occurs between the proximate projections and a wall of a retaining groove of the holder to produce radial shifting of the gap of the clip toward the axis of the bit. Removal of the bit from the hole is possible only by shearing the remote projection.
摘要翻译：用于工具头的保持夹包括环形带，其周向间隔开的端部限定了它们之间的间隙。一对邻近的突起和至少一个远离的突出部从条带向外突出。邻近的突起位于间隙的相对侧上。邻近的突出物包括正向定向的前表面，并且远程突出部包括相对于邻近突起的前表面的最前部分纵向向后设置的非正向定向的前表面。当夹子在保持器的孔内向前移位时，邻近的凸起与保持器的保持槽的壁之间发生接触，以产生夹子的间隙朝向钻头的轴线的径向移动。仅通过剪切远程投影才能从孔中移除钻头。

摘要： A rotary mining tool in the form of a bit symmetrical about the longitudinal axis and having a cylindrical shank rotatably supported in a support block. Cooperating elements of abutment means on the bit and the block support axial loads imposed on the bit. The bit is releasably retained in the block while permitted to rotate therein by a keeper arrangement on the rear end of the shank of the bit and which is in the form of a resilient ring on the shank of the bit at the back end of the block and a metal back up ring immediately behind the resilient ring.

摘要： Mounting means for cutting tools of the type having an elongated shank of circular cross section, a hard cutting tip at one end and an abutment surface at the other end. The mounting means comprises a body having a forward surface, a rearward surface and a shank receiving perforation extending through the body from the forward surface to the rearward surface. The shank receiving perforation is of such diameter as to permit free rotation of the cutting tool shank therein and is of such length that the abutment end of the cutting tool shank extends beyond the rear surface of the body. The body is mounted on a driven element of a mining machine. An abutment means is provided in association with the driven element, the abutment means presenting an abutment surface cooperating with the abutment surface on the cutting tool shank and spaced from the rear surface of the mounting means body.
