Patent number: 5002705Abstract: A mechanism for idling position adjustment of a diaphragm carburetor will be described. The carburetor includes an idling nozzle which receives a fuel/air emulsion from an emulsifying chamber under idling conditions. The emulsifying chamber receives fuel from a fuel chamber and air from an acceleration port opening into the mixing passage. Furthermore, the emulsifying chamber communicates via a flow control valve to a venting port opening into the mixing passage. The flow control valve is coupled to the shaft of the throttle valve via mechanical connection means so that the idle position of the throttle valve is varied in accordance with manual adjustments of the flow control valve. This allows to adjust the fuel/air ratios under idling conditions by means of a single adjustment member.Type: GrantFiled: January 18, 1990Date of Patent: March 26, 1991Assignee: Walbro GmbHInventor: Gisbert Kohler

Patent number: 4483279Abstract: A single-cylinder motor having a crankshaft mounted or journalled in the crankcase by means of roller-bearing sets. A crank web or lobe with a crankshaft pin is arranged at one end of the crankshaft. The crankshaft pin is drivingly connected via a connecting rod with the piston of the piston-cylinder unit. The other end of the crankshaft, in the region of the end segment thereof, carries the rotor of a magneto ignition device, whereby an end journal of the crankshaft can be coupled with a power take-off or output member. To journal or mount the crankshaft, the roller-body sets are arranged axially nondetachable in a sleeve which coaxially surrounds the crankshaft, whereby the sleeve is pressed or forced into a recess of the crankcase. The sleeve, the roller body sets, and the crankshaft form a structural unit capable of being preassembled.Type: GrantFiled: October 28, 1982Date of Patent: November 20, 1984Assignee: Andreas StihlInventors: Gisbert Kohler, Michael Leuchte

Patent number: 4432139Abstract: A safety device on a power saw which is provided with two handles, especially for a power chain saw. The saw has a brake which engages a drive member of the cutting tool of the saw under the effect of a force retainer; the brake is held in the ineffective or inoperative position by a stop which is actuated by operating elements associated with the two handles. The stop is locked in its locking position and is releasable by means of an adjustment device which is driven by an energy source supplied by the engine of the saw, and is controlled by a control device which is connected to the operating elements which are embodied as key or contact switches.Type: GrantFiled: October 27, 1981Date of Patent: February 21, 1984Assignee: Andreas StihlInventors: Gisbert Kohler, Hermann Weiss, Gotz Landwehr

Patent number: 4406065Abstract: A cutting head, especially grass cutting head for a free-cutting device having a main body which essentially comprises two discs spaced axially from each other and rigidly connected with each other; between and approximately parallel to the discs are arranged at least two pivotally mounted, blade-like cutting tools which, during rotation of the cutting head, project beyond the peripheral edge of the discs and, because of the arising centrifugal force, align themselves radially outwardly. A pivot pin is rigidly connected with the cutting tool; the pivot pin extends upwardly and downwardly beyond the cutting plane, and is held approximately parallel to the axis of rotation and is partially surrounded by bearing seats of the discs; these bearing seats are located axially across from each other and are open approximately toward the axis of rotation of the cutting head.Type: GrantFiled: February 9, 1982Date of Patent: September 27, 1983Assignee: Andreas StihlInventor: Gisbert Kohler

Patent number: 4370810Abstract: A portable motor chain saw with a braking device, for stopping the saw chain during recoil, and with a release, for the braking device, which in the release position is operatively connected with a locking mechanism of the braking device. The release is an inertial mass which is freely movable along an acceleration path, with the kinetic energy of the inertial mass in the release position being greater than the resistance force of the locking mechanism. The release is held in the ready position by at least one holder, preferably a spring which extends between the saw housing and the release.Type: GrantFiled: May 29, 1980Date of Patent: February 1, 1983Assignee: Andreas StihlInventors: Volker Schurr, Hans Nickel, Klaus Hoppner, Gisbert Kohler, Hermann Weiss, Dieter Wieland

Patent number: 4084860Abstract: Apparatus for mounting an open end spinning turbine positioned adjacent the front end of a drive shaft includes a bearing block which has a pair of spaced walls traversed by the drive shaft. Rollers are provided between the spaced walls forming a V-groove support for the drive shaft. The rear end of the shaft extends outwardly of the rear wall of the bearing block and has an annular T-slot formed therein. A bushing is mounted in the wall for journalling of the shaft, and a guide member extends within the T-slot for establishing the axial location of the shaft within the supporting rollers.Type: GrantFiled: May 26, 1976Date of Patent: April 18, 1978Assignee: SKF Kugellagerfabriken GmbHInventors: Gisbert Kohler, Hanns-Wilfried Munkel, Hubert Pohl, Walter Sommer, Gunther Wendel

Patent number: 3999362Abstract: A thread breakage repair apparatus for use in open-end spinning machines includes a fixture which holds the thread and trims its broken end and it also includes a movable assembly, on which a drawoff tube is mounted which is connected to a source of suction. This drawoff tube is brought close to the end of the thread held by the clamping and severing fixture, whereupon a controller releases the clamped thread which is then aspirated into the interior of the drawoff tube. The mechanical transport mechanism for the thread may be reversed in motion by the controller, permitting already spun thread to be backspaced so that the end of the thread may be reattached to the fibers located in the spinning rotor. The drawoff tube may also be of the telescoping type whose extension is determined by the controller.Type: GrantFiled: April 18, 1975Date of Patent: December 28, 1976Assignee: Zinser Textilmaschinen GmbHInventors: Gunter Schulz, Gisbert Kohler
