Abstract: Disclosed is a hoist trolley having a pair of jacking plates with apertures for attaching the plates to a compressor. Fixed to the opposing ends of the jack-plates are telescopic legs with extendable retractable wheels and a screw jack that is used to elevate the load, once the plates are attached, enabling the wheels to be extended. Once extended, the jack base plate is raised with the wheels supporting the load. Transporting the load is accomplished by providing a pair of rails cantilevered from a stand. Also provides are additional elements to enhance the range of applications for the compressor trolley including a pry bar incorporating a motive member whereby the bar can be used in the similar function of supporting some part of the load while moving to a workspace and a depending pivot arm having one element of a fastener, with the other incorporated into an opposing jacking plate. Furthermore, the spaced apart trolley rails can include integral rollers.

Abstract: An adjustable length jacking column for supporting a cutting or drilling tool between spaced apart surfaces is disclosed. A speed drive serves to quickly adjust the column sections to an intermediate position closely corresponding to the distance between the spaced apart surfaces. A selectively engageable screw drive is configured to shift the column sections from the intermediate position to a secured position, in which the column length corresponds to fixed securement between the surfaces. The screw drive is drivingly connected between the column sections to shift the column sections relative to one another when engaged, and is drivingly disconnected from at least one of the column sections when disengaged so as to avoid interfering with relative shifting of the column sections by the speed drive.

Abstract: A girder block lifting method, which can solve a problem that steel beams are inclined or fallen inward by lifting a heavy material, and a jack-up stage used therefor are provided. The method includes a main beam which can be provided between steel beams being targets of connection with the girder to construct a rigid frame structure, a height adjustment means (gate-shaped base) mounted on a cross beam member being parallel to the main beam and connecting other steel frames for adjusting height to the main beam, a connection beam for alternately connecting the main beam and the height adjustment means (gate-shaped base), and an auxiliary beam for connecting the connection beams. On a frame stage formed by connecting these beams, a plurality of lifting jacks are provided and a lifting sling is hung from upper part of the steel beam to enable jack-up of the girder block.

Abstract: An adjustable support bracket to be used in combination with a support pier or post to support a structure subject to weights or loads. A support pier is placed in proximity to a surface requiring support. At the end of the support pier, in proximity to the surface requiring support, a generally rigid flat surface is placed. On that flat surface are a plurality of support bolts generally perpendicular to the flat surface. The bolts are threaded and are provided with locking nuts. A matching second flat surface is placed above the first flat surface and between the first flat surface and the structure requiring support. A plurality of sleeves are on the second flat surface. The sleeves are sized and shaped for receipt of the support bolts on the first flat surface. The sleeves are slipped over the bolts on the first flat surface, leaving a space between the first and second flat surfaces.

Abstract: The motorcycle support stand is a compact and folding device used as an additional support to a motorcycle when parking the motorcycle in a location where firm ground is not available, specifically a muddy field or a location having unstable or uneven ground conditions not conducive to the motorcycle being supported by its own kick stand. The device, comprising a base support frame and an adjustable height pedestal with a frame engaging trough, is compact and storable, being presented in several component parts without requiring any tools, and may be adjusted to the height of any motorcycle, being adapted to any motorcycle.

Abstract: An adjustable base assembly for selectively adjusting the horizontal and vertical position of a fabricating tool such as a punch or metal forming tool. The apparatus includes a generally planar base and a carriage assembly positioned on the base. The carriage assembly includes a lower wedge plate assembly having an upper surface defining a pair of upwardly converging wedge faces, an upper wedge plate assembly having a lower surface defining a pair of downwardly converging wedge faces, a pair of wedge blocks each having converging upper and lower wedge faces for respective sliding engagement with one of the upwardly converging wedge faces and one of the downwardly covering wedge faces, and a vertical adjustment screw mounted on the lower wedge plate, passing through the wedge blocks, and including left and right threaded portions for respective threaded coaction with a left threaded bore in one of the wedge blocks and a right threaded bore in the other wedge block.

Abstract: A lateral trailer tongue jack has a base plate for resting on a ground surface beneath a trailer tongue. The base includes a lateral channel iron track having a framework disposed over the track. A vertically oriented tubular socket has a wheel mounted at a lower end thereof which rides in the track. A lead screw disposed laterally across the framework is engaged with a threaded floating carriage within the socket. The socket accepts the lower end of a vertical tongue jack of the trailer. A crank attached to the lead screw is used to move the socket laterally along the track to align the trailer tongue hitch socket with the hitch ball of a towing vehicle.

Abstract: An apparatus for removing support and guidance rollers from an endless track vehicle so that the rollers may be repaired or replaced. The apparatus includes a tool having a base on which a generally vertical threaded shaft is mounted and such shaft may be selectively rotated to raise and lower a travelling block and such block carries a generally horizontal threaded shaft having a cradle or other support means at one end which receives and supports an endless track support and guidance roller when such roller is to be removed and replaced.

Abstract: A movable base jack includes a jack pad, a guideway integrally connected to the pad and a jack column connected to a wheel assembly which rolls in the guideway. The wheel assembly can move in a longitudinal, rotational and arcuate direction in the guideway and is captivated to the pad.

Abstract: A method and apparatus to assemble two structures wherein a first structure is substantially permanently placed and a second structure is to be moved to be contiguous with the first structure. Traversing assemblies include a movable platform supported on bearings, and traversing means to move the platforms. The structure is supported on three jacks, the jacks resting on the platforms of the traversing units, and the traversing means are operated to move the second structure until it is contiguous with the first structure.

Abstract: An automobile jack having a pivotal center post mounted in a swivel base and a pair of opposed legs which enables the user to move the car after it has been raised by the jack. The legs are caused to translate together in opposing directions by means of a crank and gear mechanism to cause the post leg while the car is raised to pivot and thereby shift the car in the desired direction for balancing purposes in order to secure the car in its raised position.
