20100264608 | CHUCK ASSEMBLY FOR A DOWN-HOLE DRILL - A chuck assembly, an assembly for an earth-boring drill assembly, and a method of retaining a drill bit for an earth-boring drill assembly, the drill assembly including a casing. The assembly includes a drill bit having a generally cylindrical head, a chuck connectable to the casing and operable to support the bit, the chuck having an outer surface with a radially-outwardly extending chuck ridge, an axially-extending first slot being defined in the ridge, a sleeve having an inner surface with a radially-inwardly extending sleeve ridge engageable with the chuck ridge to limit axial movement of the sleeve relative to the chuck, the sleeve having a first lug supported on the inner surface, the first lug being positionable in the first slot to limit relative rotational movement between the sleeve and the chuck. The assembly may also include a retainer assembly provided between the sleeve and the bit. | 10-21-2010 |
20120187639 | HOLDING DEVICE FOR HAND MACHINE TOOLS, IN PARTICULAR HOLDING DEVICE FOR A DRILL AND/OR CHIPPING HAMMER - A holding device for hand machine tools, in particular a drill and/or a chipping hammer holding device, includes a hammer tube and at least one blocking body, which, when installed, connects the hammer tube to at least one additional holding component. The blocking body is provided with at least one blocking surface that is curved around at least one load tipping axis. | 07-26-2012 |
20130056940 | TOOL RECEPTACLE - A tool receptacle is disclosed. The tool receptacle has a receiving sleeve which has a prismatic or cylindrical cavity for receiving a tool and an elongated hole for receiving a locking body. The elongated hole has a closed edge formed of two opposing longitudinal sides at a constant distance and two end sides completing the elongated hole. An extension along the working axis of at least one of the end sides is less than half of the constant distance of the opposing longitudinal sides. A groove running parallel to the working axis is provided on an inner surface of the receptacle sleeve. The groove is disposed in an extending manner at the elongated hole on the inner surface along the working axis. | 03-07-2013 |
