摘要： A constrained layer damper and noise suppressor which is made an integral part of a rock drill steel shaft. Rearward of the drill bit a viscoelastic layer constituting a damping medium is bonded around the drill steel for a major portion of its length. Coextensive with the outer diameter of this medium a smooth thin walled rigid abrasive resistant tube is bonded. Usually the diameter of the constraint tube is less than the major diameter of the drill bit so the entire invention can penetrate a drilled hole.

摘要： A cutter chain, especially for the excavation of formations, in which the chain is made up of links pivotally interconnected in end to end relation with blocks mounted on the links and inclined at relative angles in opposite directions relative thereto and carries a pick type bit having a point end inclined forwardly in the direction of movement of the chain. Advantageously, each bit is rotatably mounted in a sleeve which, in turn, is rotatably mounted in a respective block.

摘要： Mounting arrangements for roller-type earth cutters, used in continuous boring or tunneling machine, which prevent an excessive loading of a cutter. In one embodiment, spring-type means urge the cutters outwardly from a support and thrust surface, such as a cutterhead, and yields under a predetermined load to allow inward movement of the cutter to prevent overloading thereof. In another embodiment, hydraulic-fluidpressure-powered plungers, manifolded together from a common source of fluid pressure, urge cutters against the work face, and excessive loading of any one cutter displaces some of its plunger fluid to other cutter plungers whereby the loading is substantially averaged for all cutters.

摘要： A replaceable wear-resistant element assembly is described having a wear-resistant element and a mounting device for releasably securing the element in the recess of a supporting body. The mounting device is constructed of a one-piece goblet shaped unit having a sleeve portion for receiving the element therein and a stem portion for supporting the element. The stem and sleeve portions are interconnected by a shearable web portion which will fracture when an axial force of sufficient magnitude is applied to the sleeve to cause the sleeve to move downward about the stem to release the element.

摘要： A cutter tool for an earth-boring machine comprises a disc or ring of a metal or alloy having a Rockwell C hardness of at least 60 and having a circumferential cutting edge on its outside surface. The inner surface of the ring, or of a steel liner on which the hard metal ring is mounted, has a tapered crosssectional configuration. A first annular support engages one of the inner tapered surfaces and a second annular support the other tapered surface. These annular supports may be drawn toward each other to exert a hoop stress on the hard metal ring thereby placing it in a prestressed condition. The hard metal ring, its optional steel liner and the supports constitute an assembly which is rotatably mounted on a shaft. The shaft includes means for attachment to an earth-boring machine with the shaft in axial alignment with a radius of the bore.

摘要： This invention relates to a lock for the key which holds a digging tooth point on an adapter. The lock comprises a roller that is engageable with a recess in the key and is mounted in an open-ended cage so that it cannot move laterally or longitudinally with respect to the key but is free to rotate on a transverse axis and to move toward and away from the key. A rubber backup plug biases the roller toward the key, but does not prevent its rotation.
