Abstract: An apparatus and method for cutting rolled window shades, and the rollers on which they are mounted, includes a shade holder having a generally cylindrical tubular handle with a longitudinal central opening and a disc-like, annular cutting guide extending transversely outward from the end of the handle. In one form of the apparatus, the handle and guide are longitudinally split into two pieces and hinged at one side of the guide so the shade holder can swing open to receive a shade. In another form, the handle and guide are slotted longitudinally so as to be diametrically variable. A generally annular blade holder has a circumferential guide groove opening inwardly towards the center of the blade holder for engaging the outwardly-extending cutting guide on the shade holder. The blade holder supports a blade having a cutting edge positioned normal to the longitudinal axis of the shade holder and adjacent the end of the shade holder.
Abstract: A tool-clamping device especially for a pipe cutoff machine, and a method of setting up a pipe cutoff machine. The clamping device includes a base and an overlying cap between which the tool is clamped. Spring means within the base and cap urge the cap to a tool-releasing position. Hydraulic means within the base pull the cap to a tool-clamping position against the action of the spring means. In setting up the machine, a tool is lightly clamped in the device, moved into contact with a pipe chucked in the machine to adjust the overhang, and firmly clamped for cutting.
Abstract: A unique method and apparatus for making a score cut on a metal object with a previously used abrasive cutting wheel, worn down from a new, larger diameter wheel to allow use of worn cutting wheels and to improve the ratio of cross-sectional area of metal material cut to cross-sectional area of wheel used. Another feature is the use of a hydraulic bearing for reducing friction between the object rotating chuck stands and the track on which the stands are moved by simultaneously flushing the abrasive particles from the track. In one embodiment, the flushing material is recycled to replenish the coolant reservoir fluid loss through evaporation.
Abstract: Apparatus is disclosed for cutting open a blow-molded container such as a refuse can. A pair of knife blades are pivotally mounted to a knife which is pivotal about an axis orthogonal to the axis of pivot of the blades. The knife has a pair of cam followers for guiding it around the container by following a cam track conforming to the shape of the article.
Abstract: Method and apparatus for trimming cylindrical articles, particularly can bodies, to a predetermined longitudinal length by sequentially feeding such cylindrical articles into carriage pockets rotating around a main shaft synchronously with an axially aligned plunger at one end of each carriage pocket and a similarily aligned mandrel at the other end of the carriage pocket. At predetermined positions, the plunger moves into the aligned carriage pocket and pushes a cylindrical article therein onto an aligned mandrel which is rotated around its own axis as well as around the main shaft. As the mandrel rotates, a fixed arcuate blade which cooperates with a cutting edge defined in the mandrel is engaged to shear an annulus portion from the end of the cylindrical article thereby trimming the cylindrical article to a predetermined and repeatable length. Upon severing of the annulus, a fixed cutter blade engages the annulus to transversely cut the annulus into an open ring.
Abstract: Inspection of can double seams is performed by cutter which approaches can in a relative direction and location to both sever the cover hook and move it along the can without damage to the body hook. The cutter is caused to move at a small angle away from the can during the cutting action to avoid damage to the body hook.
Abstract: In a method and apparatus for trimming flash from blow molded articles with a rotating blade as they traverse a path of travel between a fixed guide and a rotary drive wheel, improvements are provided which include a mounting for the blade eccentrically offset from the axis of the drive wheel which allows the articles to be firmly supported by the guide and drive wheel before cutting commences, thereby improving the quality of the cut from the standpoint of reducing variability in planarity and in vertical position with respect to adjacent portions of the usable part of the article.
Abstract: In trimming moils from plastic articles with a blade interposed in a path along which the articles are moving while engaged with fixed and moving guides, the improvement downstream of the blade is provided of a rotatably driven moil discharge wheel and an opposite cooperating anvil forming a moil discharge path between them. The process improvements involve engaging the moil after cutting by the blade with the surfaces of the wheel and anvil and conveying the engaged moil along a path away from that taken during cutting by means of the revolving wheel.
Abstract: In trimming moils from plastic articles with a blade interposed in a path along which the articles are moving while engaged with fixed and moving guides, the improvement is provided of a retractable blade assembly movable between operative and inoperative positions by fluid motor power to permit passing articles through the path either while being trimmed or not, depending on up or downstream conditions. Means may also be included for shifting one of the guides, preferably the stationary one, into and retracted from its operative position on one side of such path.
Abstract: The present invention relates to the removal of an under-the-sink waste disposer; and more particularly relates to a tool for facilitating the removal of such a waste disposer that must be removed for replacement or for repair. The disclosed tool obviates the need for a plumber to crawl into a small cabinet, and to struggle with corroded and rusted fasteners. Instead, the disclosed tool permits the plumber to work from above the sink, where there is plenty of room.A portion of the disclosed tool is dropped into the sink drain; and cuts away the element that supports the waste disposer. In this way, the plumber may work with ease; and may remove the waste disposer from the under-the-sink cabinet when the disposer has been completely freed from the sink.
Abstract: A method and apparatus for handling a large fabric roll and an interengaging spindle therefor before and after a slitting operation in which the roll and spindle are supported in initial handling positions in longitudinal spaced and aligned relation, the spindle being supported initially at two positions at its end portions and moved longitudinally by the support at its remote end portion into interengaged relation, during which movement, the support at the other end portion is progressively changed in a direction toward the remote end and then removed after the end portion has initially engaged within the roll. The slitting operation is performed after support of the roll has been transferred to the outwardly extending spindle end portions and the roll has been transversely moved into an operative slitting position. The handling procedures are substantially reversed after the slitting operation.
