| 101 | Method and apparatus for pre-stretching continuous chain-link drilling mud separation belt | US352763 | 1999-07-14 | US6116295A | 2000-09-12 | J. Terrell Williams |
| A wide endless-loop chain-link drilling mud separation belt formed of a plurality of laterally adjacent jointed links hinged together by transverse rods is pre-stretched prior to its installation and use on a drilling mud separation unit to prevent subsequent elongation, distortion, misalignment, chain tooth jumping, and side loading. The chain-link belt is installed on and driven in a continuous loop around a pair of parallel spaced cylindrical rollers adjustably mounted transversely in a rectangular frame of a hydraulic tensioning machine. The drive roller has a plurality of axially spaced circumferential rows of radially extending teeth that engage the openings in the links and the other roller has a smooth circumference. The drive roller and rear roller are mounted in inner front and rear tensioning frame assemblies, respectively, that are connected by hydraulic cylinders which extend and retract to move the rollers relative to one another and adjustably apply and maintain tension force in the moving chain-link belt as it is driven in a continuous loop over a period of time sufficient to achieve the desired linear expansion. In a preferred embodiment, the cylindrical rollers are formed of a metallic drum having a thick outer elastomeric layer and the teeth of the drive roller are machined into the surface of the elastomeric material to prevent metal-to-metal contact and reduce heat, wear, and friction. | ||||||
| 102 | Apparatus and method for installing wire fencing | US339089 | 1994-11-14 | US5582216A | 1996-12-10 | Michael T. Smith; Barry K. Cole |
| An apparatus and method for installing wire fencing including a support frame drawn by a conveyance and supporting an upstanding wire unit support spindle. A plurality of wire fencing units which may include one or and a combination of one or more wire fencing balls or spools of stranded wire fencing or a roll of field fencing are placed coaxially about the upstanding support spindle. Separator plates are placed between the wire fencing units and then the free wire ends are attached to a fence posts. The conveyance moves along a line of fence posts and the wire fencing of each of the wire fencing units is simultaneously dispensed. A drag assembly applies a drag force against a portion of the support spindle to prevent uncontrolled pay-out of the wire fencing as the wire is dispensed. A clamp assembly, selectively engagable with portions of the payed-out is provided for isolating pulling tension form wire remaining supported on wire units as the fencing is stretched prior to attachment to the fence posts. A dispensed wire installation post assembly is provided to organize payed-out wire fencing to prevent tangling prior to attaching the payed-out wire fencing to the fence posts. | ||||||
| 103 | Concrete reinforcement mesh lifting tool | US44493 | 1979-06-01 | US4191360A | 1980-03-04 | Donald R. Morrison |
| A tool for lifting concrete reinforcement wire mesh comprises a lever and support structure enabling the pivot point to be adjusted vertically as well as along the length of the lever. | ||||||
| 104 | Wire mesh working apparatus | US22319072 | 1972-02-03 | US3814144A | 1974-06-04 | SPENCER O |
| A reinforcing wire mesh working apparatus includes a frame having pairs of support wheels and a spindle for rotatably supporting a roll of wire mesh web on the frame so that the web may be unrolled and passed beneath a pair of the support wheels for decontouring the web; the frame, which may be adjustable in height or length, also carries additional decontour means and a removable bender for bending the web to desired angular configurations, the additional decontour means and the spindle may be mounted in different positions on the frame. Two manually operable embodiments of the wire mesh working apparatus are disclosed. Also disclosed is a powered wire mesh working apparatus which includes an electrically powered web feed device, and a hydraulically powered bending mechanism, web cutter and frame height-adjusting means.

| 105 | Apparatus for determining the gauge of wire screen or mesh | US3732899D | 1971-09-03 | US3732899A | 1973-05-15 | SCHINDLER W |
| An apparatus for use in the manufacture of wire screening or mesh which determines the pitch thereof. The apparatus incorporates a means for drawing the completed wire screen or mesh through a welding apparatus. A plurality of flexible chain drives incorporates upwardly extending dogs which selectively engage the wire mesh and the transverse members thereof. The dogs are movable so as to adjust to a different pitch. The chain drives are advanced by means of a ratchet mechanism, the stroke thereof being variable. The stroke can be varied, for example, from two inches to about six inches.

| 106 | System for forming and handling annular rod bundles | US3710711D | 1971-08-24 | US3710711A | 1973-01-16 | BOEHM W; TORRANCE G |
| Rod delivered in a series of rings to an elevated gathering tub, in a conventional manner, is formed into an annular bundle around a mandrel of a rod bundle carrier having a base platform secured at right angles to the mandrel, the carrier being elevated so that the mandrel projects into the gathering tub as the bundle is formed and loaded onto the base platform of the carrier. The loaded carrier is lowered from the gathering tub, and is then detachably suspended from a load unit of an overhead power and free conveyor which transports the loaded carrier to other stations where operations are performed on the rod bundle. At each of these other stations the bundle is not separated from the carrier but the carrier is detached from the conveyor, employed as part of the apparatus for carrying out the operation, and resuspended from the conveyor, the loaded carrier eventually arriving at at an unloading station where the processed bundle is removed from the carrier.

| 107 | Wire mesh working apparatus | US3688810D | 1970-04-06 | US3688810A | 1972-09-05 | SPENCER OWEN C |
| A reenforcing wire mesh placement apparatus is provided having a rotating spindle for placing a roll of tightly wound wire mesh for reenforcing concrete, or the like, and haVing a decontouring drum rotatably connected for unravelling the wire in a manner to decontour and flatten the rolled wire. A frame is provided which has lifting means for lifting the apparatus for the placement of wire mesh at various levels of a multi-levelled building during construction. A guard is also provided for flattening uneven spots in the wire mesh during the decontouring operation and the frame has several operable positions for working in different positions or for movement between locations. The frame can also be provided with wheels and can be power-actuated and may be connected to the work table for cutting and bending the wire mesh as desired. A power operated enlarged drum may also be added for holding the decontoured wire until ready for use or for rewinding the decontoured wire into an enlarged roll for ease in working therewith.
