Patent number: 5553367Abstract: The disclosure involves a structural combination and a method for attaching a machine component such as a number of arc-shaped gear segments to a supporting segment mounting pad. As new, each gear segment is furnished with a number of openings, all of the same diameter. Initially, the mounting pad is free of openings and each gear segment is placed on the pad and used as a drilling template. After openings are drilled in the mounting pad, a number of such openings (but not all) are "opened up" by reaming and a bearing-fit bolt is inserted into the reamed openings. In repair, a new gear segment is placed at a position which spans two places formerly occupied by gear segments. Certain openings in the new segment are aligned with existing openings in the mounting pad (to receive clearance-fit bolts therethrough) and other segments openings are used to form new openings in the mounting pad.Type: GrantFiled: September 6, 1994Date of Patent: September 10, 1996Assignee: Harnischfeger CorporationInventor: John P.

Patent number: 5548198Abstract: The disclosure involves a drive system having a control section, an adjustable frequency drive unit coupled to the control section, and first and second drive motors. The drive system is used with a material handling machine such as a light-duty crane on which any two of the hoist, bridge and trolley drives are rarely used simultaneously and in any event need not be used simultaneously. The drive unit is a scalar or flux vector (feedback-type) inverter and is the sole drive unit providing electrical power to the drive motors. Preferred control is by a pendant station or radio transmitter. Operating a pushbutton on the pendant station (or a paddle-like stick control on the transmitter) for a particular drive motor "locks out" operation of the other motors. Motors are operated on a first-come, first-served basis.Type: GrantFiled: September 30, 1994Date of Patent: August 20, 1996Assignee: Harnischfeger CorporationInventor: Jon E. Backstrand

Patent number: 5522271Abstract: Disclosed is a soil sampling tool having a barrel and a plug in the barrel for expelling a soil sample from the barrel. In the improvement, the plug is imperforate and includes a frangible section attached to the barrel. When the soil sample is expelled as, e.g., into a lab vial, force is applied to the plug, breaking the frangible section and urging the plug and the soil sample out of the barrel. Since it is imperforate, the plug prevents VOC vapors from migrating out of the mouth portion and the barrel is thereby made suitable for a single use and is disposable. The advantages include avoidance of sample "cross-contamination." A new method for analyzing a soil sample including the steps of providing a sampling tool having a barrel, a mouth portion and a plug retained in the barrel by a frangible section. The mouth portion is filled with a soil sample and the plug is urged toward the mouth portion, thereby breaking the frangible section and expelling the soil sample from the tool.Type: GrantFiled: July 21, 1995Date of Patent: June 4, 1996Assignee: En Chem, Inc.Inventors: David E.

Patent number: 5522536Abstract: A method and apparatus are used to mount a machine component, e.g., an electric motor, in alignment with another component such as a gear shaft of a gear transmission. The apparatus includes a bolt-attached U-shaped clamp device straddling a "foot-like" transmission mounting base. The legs are spaced greater than the horizontal thickness of the base to permit slight base movement during mounting. The clamp device has an interior height somewhat less than the vertical height of the base. The base is shimmed so that the motor shaft is vertically aligned with the gear shaft, horizontal and angular alignment is performed and then the clamp legs are shimmed. Leg shimming is to a height such that when the clamp bolts are tightened, the base shims are under substantial compressive force and the leg shims are under only somewhat less compressive force. One or more chock blocks are welded to the machine deck to help maintain base position.Type: GrantFiled: October 14, 1994Date of Patent: June 4, 1996Assignee: Harnischfeger CorporationInventor: Harvey J.
