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.

摘要： A cutter device for use with mining machines and consisting of a cutter member having a shank and a head portion extending generally transversely of the shank and a holder member with a recess in which the shank is received. The shank has a depression which locates a locking pin used to secure the cutter member to the holder member. The head portion of the cutter member has a cutting edge at one end and a projection at the opposite end. The holder member has a tapered neck extending upwardly from a wall surface penetrated by the recess to engage the projection and provide a support for the cutter member. The cutter member has a transition portion between the shank and the head portion and this portion has a surface co-extensive with a surface of the shank which surfaces engage similarly co-extensive surfaces of the neck and the interior of the recess. A shoulder can be formed beneath the cutting edge and spaced from an abutment surface on the holder member.
摘要翻译：一种用于采矿机的切割装置，包括具有柄和头部大体上横向延伸的刀片的刀具构件和具有凹部的保持构件，柄部被容纳在该凹部中。柄具有凹部，该凹陷部定位用于将切割器构件固定到保持器构件的锁定销。刀具部件的头部在一端具有切削刃，在相对端具有突出部。保持器构件具有从由凹部贯穿的壁表面向上延伸的锥形颈部，以接合突起并为切割器构件提供支撑。切割器部件在柄和头部之间具有过渡部分，并且该部分具有与柄的表面共同延伸的表面，这些表面与颈部的类似的共同扩展的表面和凹部的内部接合。可以在切割边缘下方形成肩部并与保持器构件上的邻接表面间隔开。

摘要： A mining bit with a cylindrical shank has a support block with a longitudinal bore therethrough for receiving a bushing of hard material. The shank is rotatably received in the bushing. The bit is held from axial movement and the bushing from axial and rotational movement by means of a single keeper. The keeper has a body portion which is received in a transverse bore in the block and a matching opening in the bushing. The keeper also has a protuberance which extends into a circumferential groove in the bit shank. The protuberance is depressible to move it out of the groove.
