Abstract: This invention provides a quick and accurate gauging means for locating and clamping a guide onto the top surface and leading edge of a workpiece, with respect to the line of cut desired. During execution of the cut, the gauging member of the guide is automatically returned to its storage position and cocked for the next cut. This guide is completely operable with only one hand, leaving the other hand simultaneously free for holding and operating the portable hand power saw. This invention yields cuts that are accurate and more quickly executed than freehand cuts or cuts where other types of saw guides are employed.

Abstract: A straddle block is used with a table saw having a rip fence, and consists of a body having a substantially vertically extending fixed leg, a bridge extending from the fixed leg, an adjustable leg attached to and vertically displaceable relative to the bridge. The vertically adjustable leg may be reversed for right or left-handed use, and has opposing, substantially horizontal, rectilinear edges for engaging an upper surface of a piece of stock to be cut on the table saw, and opposing outwardly extending step portions adjacent an end of each rectilinear edge for engaging the trailing end of the stock as it is pushed across the saw table. The bridge spaces the fixed leg from the adjustable leg sufficiently to receive a rip fence therebetween such that the straddle block may slidably engage the rip fence without skewing relative thereto.

The trim portion fits over the two plates to provide a pleasing appearance and to lend mechanical rigidity to the mounting track system.

Abstract: An earth boring machine is shown with an improved kelly seal. The machine includes a hydraulic cylinder and a kelly rotatably carried within the cylinder and axially movable with respect to the longitudinal axis of the cylinder. A rotary quill surrounds the kelly for supplying rotational force to the kelly. A packing assembly carried about the kelly within the hydraulic cylinder proximate and end thereof seals hydraulic fluid within the hydraulic cylinder. An improved retaining assembly connects the packing assembly to the rotary quill but allows limited relative rotational movement of the packing assembly with respect to the rotary quill about the longitudinal axis of the kelly. The limited movement provided by the retainer assembly isolates the packing assembly from drive torque which is transferred from the rotary quill to the kelly, thereby reducing the tendency of the packing assembly to drive the kelly.

Abstract: Web slitting apparatus is provided with a web guide below the web path. The web guide is moveable between operative and inoperative positions. In the inoperative position, the web guide has a portion for supporting a central portion of the web when it is desired to process a web as mill run board.

Abstract: A bucking station for small logs is disclosed, in which a log is scanned to determine its size and shape, the resulting data are analyzed by a computer which determines the optimum locations for cuts, and the proposed cut locations are displayed on the log optically for the operator's inspection. If the operator overrides any of the proposed cuts, the computer recalculates any cuts not specified by the operator. When all cuts have been approved, the log is kicked to a cutting bed, where the cuts are made by means of two independently controllable traveling saws. The cutting bed is preferably defined by three sets of parallel plates. The first set comprises stationary plates having V-shaped upper edges which define a V-shaped trough in which the log is initially received. The second and third sets of plates are vertically movable and, when raised, together define a second V-shaped trough located above the first trough.
