Patent number: 7240869Abstract: A lubricating system for a heavy-duty metal demolition shears provides lubricating lubricant to one of more wear parts. The system includes a hydraulic lubricant pump that is actuated by the main hydraulic control system that opens and closes the jaws of the shears. The lubricant pump may include a sequential valve to distribute lubricant to various wear parts in sequential fashion. As disclosed herein, wear parts that may be lubricated by a lubricating system as per the invention include (but are not limited to) lateral blade stabilizers, a guide blade, and cutting blade insert members.Type: GrantFiled: July 8, 2004Date of Patent: July 10, 2007Assignee: The Stanley WorksInventors: Clayton P. Sederberg, Michael W. Swanson

Patent number: 7237738Abstract: A demolition cutter which can smoothly cut an object while eliminating the possibility of any gap being formed between mating surfaces having cutting edges. The cutter includes an arm pin 8 extending between a pair of side plates 6 of a movable bracket 3. Two arms 9a and 9b are mounted on the arm pin 8 so as to be pivotable about the pin 8 between open and closed positions. Cylinders 14a and 14b are connected to the arms 9a and 9b, respectively. The arms 9a and 9b have mating surfaces 11 formed with cutting edges adapted to cut an object when they cross each other. The cylinders 14a and 14b have their axes offset outwardly from the mating surfaces 11 so that when the cylinders are extended, the arms 9a and 9b are closed with their mating surfaces 11 in close contact with each other. This prevents the formation of a gap between the mating surfaces during cutting.Type: GrantFiled: August 4, 2003Date of Patent: July 3, 2007Assignee: Nippon Pneumatic Manufacturing Co., Ltd.Inventors: Sehiro Kimura, Tomoki Uchida

Patent number: 7234659Abstract: An automatically swiveling crushing apparatus has a swiveling motor in a bracket, and branches diverged from charging and discharging paths that constitute the hydraulic piping leading to a cylinder for closing or opening distal crushing arms. One of the branches extends from one of the paths then operating to open the end arms, so that a portion of the hydraulic fluid is fed to the hydraulic motor if and when internal pressure in this branch has exceeded an upper limit. The other branch extends from the other path leading to the cylinder so as to close the end arms, and this branch prevents any amount of hydraulic fluid from flowing back to the motor. The branches render dispensable a discrete or independent hydraulic piping in a self-propelled platform having a proximal working arm to be connected to the apparatus, saving cost and labor in connecting this arm to the apparatus.Type: GrantFiled: February 7, 2001Date of Patent: June 26, 2007Assignee: Okada AiyonInventors: Tetsurou Torihara, Naoto Iwamoto

Patent number: 7222807Abstract: A bucket for crushing and screening stone and similar materials. The bucket has a scoop-shaped body defining an inlet opening for the stone to be crushed and an outlet opening for the crushed stone, between which a direction of flow of the stone is defined. The bucket further has a stone-crushing mechanism including a first jaw and a second jaw housed in the scoop-shaped body and movable relative to one another. The bucket still further has an element for moving the first jaw relative to the second jaw. The element imparts to the first jaw a combined rotational and translational movement relative to the second jaw in which a first component of the movement is away from and towards the second jaw and a second component of the movement is substantially parallel to the direction of flow.Type: GrantFiled: August 29, 2002Date of Patent: May 29, 2007Assignee: Meccanica Breganzese S.r.l.Inventor: Guido Azzolin

Patent number: 6926217Abstract: A heavy-duty demolition shear for attachment to the boom structure and hydraulic system of an excavator, has a rigid lower jaw and an upper jaw and pivot interconnecting the jaws together. The shear is attachable to the boom structure of the excavator. The upper jaw has upper shear blades, while the lower jaw has at least one lower shear blade. The lower jaw also has a rigid guide blade lying along the lower shear blade and in spaced relation therewith. The outer ends of the shear blade and guide blade are co-extensively opposed to each other so that a tie plate secures the outer ends of the lower shear blade and the guide blade together. There is an open slot between the lower shear blade and the adjacent guide blade to receive the upper shear blade and upper jaw therein. The upper jaw has a cylinder attached to the hydraulic system of the excavator for closing and opening the upper jaw relative to the lower jaw.Type: GrantFiled: March 14, 2000Date of Patent: August 9, 2005Assignee: Genesis Attachments, LLCInventors: Kenneth R.
