Patent number: 10376965Abstract: A drilling chuck for operation on an impact drilling spindle, which can be subjected to tangential loading, with a chuck body, which is connected or connectable to the impact drilling spindle in which jaw guides are formed, which run inclined to the chuck axis in which jaw guides and clamping jaws are guided, which can be adjusted by a threaded ring, with a clamping sleeve, which can be coupled in a torque-transmitting manner to the threaded ring, and with a locking device, which is adjustable between a release configuration, which enables a relative rotation of the threaded ring with respect to the chuck body and a locking configuration, which obstructs or prevents this relative rotation. The locking device is formed from a locking sleeve, which is mounted essentially rotationally fixed but axially displaceable with respect to the chuck body, which comprises at least one locking member.Type: GrantFiled: May 31, 2017Date of Patent: August 13, 2019Assignee: Roehm GmbHInventors: Patrick Hengsberger, Hans Baumann, Peter Schenk

Patent number: 9403217Abstract: A drill-chuck body is rotatable about an axis and formed with a plurality of passages opening axially rearward at a rear face of the body and radially outwardly at windows in a side of the body. Jaws displaceable between front and rear positions in the passages each have a row of teeth exposed radially outwardly at the respective windows. A tightening ring rotatable about the axis is formed with an internal screwthread engaged at the windows with the teeth such that rotation of the ring moves the jaws between the front and rear positions. A tightening sleeve fitted around and coupled rotationally to the tightening ring extends axially rearward past the windows. This brace ring is radially inwardly engaged with the body and engages radially outwardly between the windows and the rear face with the tightening sleeve so as to coaxially center it on the body.Type: GrantFiled: November 8, 2013Date of Patent: August 2, 2016Assignee: ROEHM GMBHInventors: Peter Schenk, Markus Nusser, Hans Baumann

Patent number: 9010767Abstract: A chuck has a chuck body at least generally centered on a body axis and a collet in the hole and having an external screwthread. A ring axially nondisplaceable in the body has an internal screwthread engaging the screwthread of the collet and external gear teeth. The body is formed with a radially outwardly open cavity seat in which some of the teeth of the ring are exposed. A gear fitted in the seat meshes with the ring teeth and can rotate about a drive axis not parallel to the body axis to rotate the ring about the body axis. According to the invention a sleeve on the chuck extends axially across and covers the seat to retain the gear therein and is formed with a through going aperture through which a tool can fit to engage and rotate the gear.Type: GrantFiled: August 30, 2011Date of Patent: April 21, 2015Assignee: Roehm GmbHInventor: Hans Baumann

Publication number: 20060018770Abstract: A valve includes a housing having an inlet, an outlet and a ram receiving chamber. A ram has a first end and a second end and is slidably supported in the ram receiving chamber. The ram has a central pin on the second end of the ram. An actuating element is connected to the ram. A plate is fixedly connected to the housing. The plate has a central bore. The plate and the ram selectively abut to form a valve seat. The inlet is in fluid communication with the ram receiving chamber. The ram has an outer wall. Fluid communicates between a portion of the ram receiving chamber adjacent to the first end of the ram and a portion of the ram receiving chamber adjacent to the second end of the ram. In the closed position, the ram abuts with the plate. The pin protrudes through the central bore in the plate. In the open position, the actuating element displaces the ram such that the ram is spaced from the plate.Type: ApplicationFiled: April 1, 2005Publication date: January 26, 2006Inventors: Hans Baumann, Dipl.
